    The goal of the African Programme for Onchocerciasis Control (APOC) is to eliminate Onchocerciasis as a disease of public Health significance and an important constraint to socio-economic development in the 19 none OCP (Onchocerciasis Control Project) countries covered through Community-Directed Treatment with Ivermectin, CDTI. In 1998, impact assessment studies were carried out in Morogoro, Tanzania during which baseline ophthalmological parameters were established. The hypothesis being tested is that CDTI will prevent or delay progression of onchocercal eye lesions and blindness. A total of 425 subjects aged 10 years or more from 14 villages within Bwakira district ofMorogoro region in Tanzania were examined for Snellen visual acuity, ocular microfilaria, lens opacities, uveitis and posterior segment disease especially chorioretinitis and optic nerve disease. Motion Sensitivity Screening Test (MSST) was carried out as well. Microfilaria was present in the anterior chamber of nearly half (49.2%) of all subjects examined. Prevalence of blindness was extremely high at 15.2%. Onchocercal lesions were responsible for blindness in 41.5% of these, followed by cataracts (27.7%), glaucoma (10.8%) and trachoma (6.2%). The main pathway to onchocercal blindness in this population was anterior uveitis with or without secondary cataracts. There is an urgent need to get CDTI underway and institute other horizontal primary eye care measures, especially cataract backlog reduction, in order to reduce the excessive burden of avoidable blindness in this community.

    To examine the physiological deficit to adrenergic stimulation with aging, five younger adult (3 +/- 1 yr old) and nine older adult (17 +/- 1 yr old) healthy monkeys were studied after instrumentation with a left ventricular (LV) pressure gauge, aortic and left atrial catheters, and aortic flow probes to measure cardiac output directly. There were no significant changes in baseline hemodynamics in conscious older monkeys. For example, an index of contractility, the first derivative of LV pressure (LV dP/dt) was similar (3,191 +/- 240, young vs. 3,225 +/- 71 mmHg/s, old) as well as in isovolumic relaxation, tau (24.3 +/- 1.7 ms, young vs. 23.0 +/- 1.0 ms, old) was similar. However, inotropic, lusitropic, and chronotropic responses to isoproterenol (Iso; 0.1 micrograms/kg), norepinephrine (NE; 0.4 micrograms/kg), and forskolin (For; 75 nmol/kg) were significantly (P monkeys. For example. Iso increased LV dP/dt by by 146 +/- 14% in younger monkeys and by only 70 +/- 5% in older monkeys. Iso also reduced tau more in younger monkeys (-28 +/- 7%) compared with older monkeys (-13 +/- 3%). Furthermore, peripheral vascular responsiveness to Iso, NE, For, and phenylephrine (PE; 5 micrograms/kg) was significantly (P monkeys. For example, phenylephrine (5 micrograms/kg) increased total peripheral resistence by 69 +/- 4% in younger monkeys and by only 45 +/- 3% in older monkeys. Thus in older monkeys without associated cardiovascular disease, baseline hemodynamics are preserved, but adrenergic receptor responsiveness is reduced systemically, not just in the heart.

    This research aims to further current understanding of gender differences in old age mortality. In particular, it assesses the relative importance of health behavior and baseline health conditions in predicting the risk of dying, and how their effects differ between elderly men and women. Data for this research came from a prospective study of a national sample of 2,200 older adults in Japan from 1987 to 1999. Hazard rate models were employed to ascertain the interaction effects involving gender and health behavior (i.e., smoking and drinking) and baseline health status. Gender differences in old age mortality in the Japanese are quite pronounced throughout all of our models. In addition, interaction effects of gender and smoking, functional limitation, and cognitive impairment, indicate that females in Japan suffer more from these risk factors than do their male counterparts. Failure to adjust for population heterogeneity may lead to a significant underestimation of female advantage in survival. The inclusion of health behavior and health status measures only offsets a limited proportion of this gender differential. The increased mortality risk due to smoking, functional limitation, and cognitive impairment among elderly Japanese women suggests that narrowing of gender gap in mortality may be due to not only changes in the levels of these risk factors but also their differential effects on men and women.

    To outline the design, baseline data, and 5-year follow-up data of patients with mucopolysaccharidosis (MPS) VI enrolled in the Clinical Surveillance Program (CSP), a voluntary, multinational, observational program. The MPS VI CSP was opened in 2005 to collect, for at least 15 years, observational data from standard clinical and laboratory assessments of patients with MPS VI. Baseline and follow-up data are documented by participating physicians in electronic case report forms. Between September 2005 and March 2010 the CSP enrolled 132 patients, including 123 who received enzyme replacement therapy (ERT) with galsulfase. Median age at enrolment was 13 years (range 1-59). Mean baseline data showed impaired growth, hepatosplenomegaly, and reduced endurance and pulmonary function. The most common findings were heart valve disease (90%), reduced visual acuity (79%), impaired hearing (59%), and hepatosplenomegaly (54%). Follow-up data up to 5 years in patients with pre- and post-ERT measurements showed a decrease in urinary glycosaminoglycans and increases in height and weight in patients MPS VI to date. This first report provides information on the design and implementation of the program and population statistics for several clinical variables in patients with MPS VI. Data collected over 5 years suggest that ERT provides clinical benefit and is well-tolerated with no new safety concerns.

    Some parts of a school building do not age gracefully. At many elementary and middle schools--particularly those built in the 1960s or 1970s--old gyms are as useful (and attractive) as a worn-out pair of sneakers. To save money 20 years ago, school districts often used one space as a combination gym/lunch room/auditorium. Old gymnasiums offer…

  8. Interpreting sulci on hominin endocasts: Old hypotheses and new findings

    Full Text Available Paleoneurologists analyze internal casts (endocasts of fossilized braincases, which provide information about the size, shape and, to a limited degree, sulcal patterns reproduced from impressions left by the surface of the brain. When interpreted in light of comparative data from the brains of living apes and humans, sulcal patterns reproduced on hominin endocasts provide important information for studying the evolution of the cerebral cortex and cognition in human ancestors. Here, new evidence is discussed for the evolution of sulcal patterns associated with cortical reorganization in three parts of the hominin brain: (1 the parietotemporo-occipital association cortex, (2 Broca’s speech area, and (3 dorsolateral prefrontal association cortex. Of the three regions, the evidence regarding the last is the clearest. Compared to great apes, Australopithecus endocasts reproduce a clear middle frontal sulcus in the dorsolateral prefrontal cortex that is derived toward the human condition. This finding is consistent with data from comparative cytoarchitectural studies of ape and human brains as well as shape analyses of australopithecine endocasts. The comparative and direct evidence for all three regions suggests that hominin brain reorganization was underway by at least the time of Australopithecus africanus (~ 2.5 to 3.0 mya, despite the ape-sized brains of these hominins, and that it entailed expansion of both rostral and caudal association cortices.

    Health has improved markedly in Mesoamerica, the region consisting of southern Mexico and Central America, over the past decade. Despite this progress, there remain substantial inequalities in health outcomes, access, and quality of medical care between and within countries. Poor, indigenous, and rural populations have considerably worse health indicators than national or regional averages. In an effort to address these health inequalities, the Salud Mesoamérica 2015 Initiative (SM2015), a results-based financing initiative, was established. For each of the eight participating countries, health targets were set to measure the progress of improvements in maternal and child health produced by the Initiative. To establish a baseline, we conducted censuses of 90,000 households, completed 20,225 household interviews, and surveyed 479 health facilities in the poorest areas of Mesoamerica. Pairing health facility and household surveys allows us to link barriers to care and health outcomes with health system infrastructure components and quality of health services. Indicators varied significantly within and between countries. Anemia was most prevalent in Panama and least prevalent in Honduras. Anemia varied by age, with the highest levels observed among children aged 0 to 11 months in all settings. Belize had the highest proportion of institutional deliveries (99%), while Guatemala had the lowest (24%). The proportion of women with four antenatal care visits with a skilled attendant was highest in El Salvador (90%) and the lowest in Guatemala (20%). Availability of contraceptives also varied. The availability of condoms ranged from 83% in Nicaragua to 97% in Honduras. Oral contraceptive pills and injectable contraceptives were available in just 75% of facilities in Panama. IUDs were observed in only 21.5% of facilities surveyed in El Salvador. These data provide a baseline of much-needed information for evidence-based action on health throughout Mesoamerica.

    Full Text Available An association between depression and coronary heart disease is now accepted but there has been little primary care research on this topic. The UPBEAT-UK studies are centred on a cohort of primary patients with coronary heart disease assessed every six months for up to four years. The aim of this research was to determine the prevalence and associations of depression in this cohort at baseline.Participants with coronary heart disease were recruited from general practice registers and assessed for cardiac symptoms, depression, quality of life and social problems.803 people participated. 42% had a documented history of myocardial infarction, 54% a diagnosis of ischaemic heart disease or angina. 44% still experienced chest pain. 7% had an ICD-10 defined depressive disorder. Factors independently associated with this diagnosis were problems living alone (OR 5.49, 95% CI 2.11-13.30, problems carrying out usual activities (OR 3.71, 95% CI 1.93-7.14, experiencing chest pain (OR 3.27, 95% CI 1.58-6.76, other pains or discomfort (OR 3.39, 95% CI 1.42-8.10, younger age (OR 0.95 per year 95% CI 0.92-0.98.Problems living alone, chest pain and disability are important predictors of depression in this population.

    Recent studies have proposed additional multidetector-row CT (MDCT) for prosthetic heart valve (PHV) dysfunction. References to discriminate physiological from pathological conditions early after implantation are lacking. We present baseline MDCT findings of PHVs 6 weeks post implantation. Patients were prospectively enrolled and TTE was performed according to clinical guidelines. 256-MDCT images were systematically assessed for leaflet excursions, image quality, valve-related artefacts, and pathological and additional findings. Forty-six patients were included comprising 33 mechanical and 16 biological PHVs. Overall, MDCT image quality was good and relevant regions remained reliably assessable despite mild-moderate PHV-artefacts. MDCT detected three unexpected valve-related pathology cases: (1) prominent subprosthetic tissue, (2) pseudoaneurysm and (3) extensive pseudoaneurysms and valve dehiscence. The latter patient required valve surgery to be redone. TTE only showed trace periprosthetic regurgitation, and no abnormalities in the other cases. Additional findings were: tilted aortic PHV position (n = 3), pericardial haematoma (n = 3) and pericardial effusion (n = 3). Periaortic induration was present in 33/40 (83 %) aortic valve patients. MDCT allowed evaluation of relevant PHV regions in all valves, revealed baseline postsurgical findings and, despite normal TTE findings, detected three cases of unexpected, clinically relevant pathology.

    To determine the effects of various presale radiographic findings for Thoroughbreds sold at a yearling sale on 2-year-old racing performance of those horses. 397 Thoroughbreds. Cohort study. Thoroughbreds offered for sale at a Thoroughbred sales facility in Kentucky were selected via a randomization procedure. Effects of various presale radiographic findings on the following measures of 2-year-old racing performance were determined: having started a race and having placed (ie, finished in first, second, or third place) in a race at least once, total amount of money earned, and amount of money earned per start. Of the 397 horses, 192 (48%) started in at least 1 race during the 2-year-old racing year. The odds of failure to start a race as a 2-year-old were 1.78 times as great for horses with forelimb proximal sesamoid bone osteophytes or enthesophytes as for horses without this finding (95% confidence interval, 1.01 to 3.16). The odds of failure to start a race as a 2-year-old were 2.02 times as great for horses with hind limb proximal phalanx osteochondral fragments as for horses without this finding (95% confidence interval, 0.95 to 4.31), although this result was not significant. Radiographic findings did not have an effect on total amount of money earned, amount of money earned per start, or whether horses placed in a race. Presale radiographic detection of forelimb proximal sesamoid bone osteophytes or enthesophytes or hind limb proximal phalanx osteochondral fragments in yearlings were associated with failure to start a race during the 2-year-old racing year in study horses.

    Abstract Introduction Recognition that an older person has sarcopenia is important because this condition is linked to a range of adverse outcomes. Sarcopenia becomes increasingly common with age, and yet there are few data concerning its descriptive epidemiology in the very old (aged 85 years and above). Our aims were to describe risk factors for sarcopenia and estimate its prevalence and incidence in a British sample of the very old. Methods We used data from two waves (2006/07 and 2009/10) of the Newcastle 85+ Study, a cohort born in 1921 and registered with a Newcastle/North Tyneside general practice. We assessed sarcopenia status using the European Working Group on Sarcopenia in Older People (EWGSOP) definition. Grip strength was measured using a Takei digital dynamometer (Takei Scientific Instruments Ltd., Niigata, Japan), gait speed was calculated from the Timed Up and Go test, and lean mass was estimated using a Tanita‐305 body fat analyzer. We used logistic regression to examine associations between risk factors for prevalent sarcopenia at baseline and incident sarcopenia at follow‐up. Results European Working Group on Sarcopenia in Older People sarcopenia was present in 21% of participants at baseline [149/719 participants, mean age 85.5 (0.4) years]. Many participants had either slow gait speed or weak grip strength (74.3%), and hence measurement of muscle mass was frequently indicated by the EWGSOP definition. Incidence data were available for 302 participants, and the incident rate was 3.7 cases per 100 person years at risk. Low Standardized Mini‐Mental State Examination, lower occupational social class, and shorter duration of education were associated with sarcopenia at baseline, while low muscle mass was associated with incident sarcopenia. Low body mass index (BMI) was a risk factor for both in a graded fashion, with each unit decrease associated with increased odds of prevalent [odds ratio (OR) 1.29, 95% confidence interval (CI): 1.21, 1

    Focal dermal hypoplasia is a rare X-linked dominant disorder with in utero lethality in males. Affected patients have been reported to have several different mutations in the PORCN gene on chromosome Xp11.23. Dysplastic mesodermal and ectodermal tissue causes clinical findings in the skin, skeleton, teeth, central nervous system, and eyes of affected patients. We describe the ophthalmologic findings in an 18-month-old boy with mosaicism of a novel mutation in PORCN.

    Full Text Available Myofibroblastoma of the breast (MFB is a very rare benign stromal tumor. In recent years, increase in mammographic screenings has resulted in increased diagnosis of MFB. Most cases are old males and postmenopausal women. MFB may be confused as malignant, clinically, morphologically, or by imaging. Immunohistochemistry is essential for final diagnosis in these cases. We report a case of a pathologically diagnosed MFB in an 80-year-old male patient who had coexisting prostate cancer and describe its imaging characteristics, especially magnetic resonance imaging (MRI. In this paper, histopathological and MRI findings of the MFB were discussed.

    Whole exome/genome sequencing (WES/WGS) is increasingly offered to ostensibly healthy individuals. Understanding the motivations and concerns of research participants seeking out personal WGS and their preferences regarding return-of-results and data sharing will help optimize protocols for WES/WGS. Baseline interviews including both qualitative and quantitative components were conducted with research participants (n=35) in the HealthSeq project, a longitudinal cohort study of individuals receiving personal WGS results. Data sharing preferences were recorded during informed consent. In the qualitative interview component, the dominant motivations that emerged were obtaining personal disease risk information, satisfying curiosity, contributing to research, self-exploration and interest in ancestry, and the dominant concern was the potential psychological impact of the results. In the quantitative component, 57% endorsed concerns about privacy. Most wanted to receive all personal WGS results (94%) and their raw data (89%); a third (37%) consented to having their data shared to the Database of Genotypes and Phenotypes (dbGaP). Early adopters of personal WGS in the HealthSeq project express a variety of health- and non-health-related motivations. Almost all want all available findings, while also expressing concerns about the psychological impact and privacy of their results.

    To assess the prevalence of common mental disorders (CMD) and the association of CMD with sociodemographic characteristics in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort. We analyzed data from the cross-sectional baseline assessment of the ELSA-Brasil, a cohort study of 15,105 civil servants from six Brazilian cities. The Clinical Interview Schedule-Revised (CIS-R) was used to investigate the presence of CMD, with a score ≥ 12 indicating a current CMD (last week). Specific diagnostic algorithms for each disorder were based on the ICD-10 diagnostic criteria. Prevalence ratios (PR) of the association between CMD and sociodemographic characteristics were estimated by Poisson regression. CMD (CIS-R score ≥ 12) was found in 26.8% (95% confidence intervals [95%CI] 26.1-27.5). The highest burden occurred among women (PR 1.9; 95%CI 1.8-2.0), the youngest (PR 1.7; 95%CI 1.5-1.9), non-white individuals, and those without a university degree. The most frequent diagnostic category was anxiety disorders (16.2%), followed by depressive episodes (4.2%). The burden of CMD was high, particularly among the more socially vulnerable groups. These findings highlight the need to strengthen public policies aimed to address health inequities related to mental disorders.

    To examine the cross-sectional associations between self-reported postlunch napping and structured cognitive assessments in Chinese older adults. Cross-sectional cohort study. China. Individuals aged 65 and older from the baseline national wave of the China Health and Retirement Longitudinal Study (CHARLS) (N = 2,974). Interview-based cognitive assessments of orientation and attention, episodic memory, visuospatial abilities, and a combined global cognition score incorporating these assessments. Other self-reported or interview-based assessments included postlunch napping duration, nighttime sleep duration, demographic characteristics, health habits, comorbidities, functional status and social activities. According to reported napping duration, older adults were categorized as non-nappers (0 minutes), short nappers (90 minutes). Postlunch napping was reporting in 57.7% of participants for a mean of 63 minutes. Cognitive function was significantly associated with napping (P cognition than nonnappers (P cognition than short nappers (P = .03). In multiple regression analysis, moderate napping was significantly associated with better cognition than non- (P = .004), short (P = .04), and extended napping (P = .002), after controlling for demographic characteristics, body mass index, depression, instrumental activities of daily living, social activities, and nighttime sleep duration. A cross-sectional association was found between moderate postlunch napping and better cognition in Chinese older adults. The cross-sectional design and self-reported measures of sleep limited the findings. Longitudinal studies with objective napping measures are needed to further test this hypothesis. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Background Historically, community pharmacies have not integrated tobacco cessation activities into routine practice, instead unbundling them as unique services. This approach might have limited success and viability. Objective The objective of this report is to describe the methods and baseline findings for a two-state, randomized trial evaluating two intervention approaches for increasing pharmacy-based referrals to their state’s tobacco quitline. Methods Participating community pharmacies in Connecticut (n=32) and Washington (n=32) were randomized to receive either (a) on-site education with an academic detailer, describing methods for implementing brief interventions with patients and providing referrals to the tobacco quitline, or (b) quitline materials delivered by mail. Both interventions advocated for pharmacy personnel to ask about tobacco use, advise patients who smoke to quit, and refer patients to the tobacco quitline for additional assistance with quitting. Study outcome measures include the number of quitline registrants who are referred by pharmacies (before and during the intervention period), the number of quitline materials distributed to patients, and self-reported behavior of cessation counseling and quitline referrals, assessed using written surveys completed by pharmacy personnel (pharmacists, technicians). Results Pharmacists (n=124) and pharmacy technicians (n=127), representing 64 participating pharmacies with equal numbers of retail chain and independently-owned pharmacies, participated in the study. Most pharmacists (67%) and half of pharmacy technicians (50%) indicated that they were “not at all” familiar with the tobacco quitline. During the baseline (pre-intervention) monitoring period, the quitline registered 120 patients (18 in CT and 102 in WA) who reported that they heard about the quitline from a pharmacy. Conclusion Novel tobacco intervention approaches are needed to capitalize on the community pharmacy’s frequent

    We present the MR imaging findings in an atypical pulmonary hamartoma in a 12-year-old boy. CT showed no evidence of fat or calcifications in the tumour. It demonstrated peripheral rim enhancement on arterial-phase MR images due to a compressed respiratory epithelium, and progression to nearly homogeneous contrast enhancement on delayed-phase images. Small cystic spaces were identified on MR hydrographic and contrast-enhanced images formed by invaginating respiratory epithelium, a unique imaging finding in this condition. (orig.)

    In the present survey the radiographic findings in the jaws of 124 clinically edentulous old people living at home in Helsinki, Finland, were studied, using panoramic radiography supplemented by intraoral radiographs. Only 9% of the subjects had root remains. Impacted teeth were found in 4%, radiolucent lesions in 3%, and radiopaque findings in 13%. Deviations from normal condylar structure were found in 17% and mucosal thickenings in the maxillary sinuses in 7%. The mental foramen was situated at the top of the residual ridge in 42% of the subjects. Topically situated mental foramen and condylar changes were commoner in women. The radiographic oral health status of the population studied was good.

    WHAT IS KNOWN ON THE SUBJECT?: Physical health problems, especially cardiovascular disease and metabolic disorders are far more common in people with severe mental illness (SMI) than the general population. While there are a considerable number of studies that have examined the physical health and health behaviours of people with SMI in Western countries, there have been few studies that have done this in Asia. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Unhealthy body mass index (BMI) values were observed in 44% of Thai service users diagnosed with schizophrenia despite desirable levels of exercise and relatively good diets being reported by the majority of participants. Being prescribed two or more antipsychotics was significantly associated with greater body weight and a higher BMI than in people prescribed only one antipsychotic. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health professionals in Asia should be particularly aware of the additional risks of obesity that seem to be associated with antipsychotic polypharmacy when they are promoting the physical health of people with schizophrenia. Introduction People with schizophrenia have worse physical health than the general population, and studies in developed countries demonstrate that their health behaviours are often undesirable. However, as no similar studies have been conducted in Asian countries with emerging healthcare systems, the physical health promotion challenges in these settings is unknown. Aim To identify and explore relationships between cardiometabolic health risks, lifestyle and treatment characteristics in people with schizophrenia in Thailand. Method This cross-sectional study reports the baseline findings from a physical health check programme using the Thai version of the Health Improvement Profile. Results Despite desirable levels of exercise and relatively good diets being reported by most of the 105 service users, unhealthy body mass index values were observed in 44% of

    Plasminogen Activator Inhibitor 1 (PAI-1) is elevated in obese individuals with type 2 diabetes (T2DM) and may contribute, independently of traditional factors, to increased cardiovascular disease (CVD) risk. Fiber intake may decrease PAI-1 levels. We examined the associations of fiber intake and its changes with PAI-1, before and during an intensive lifestyle intervention for weight loss (ILI) in 1,701 Look AHEAD participants with dietary, fitness and PAI-1 data at baseline and 1-year. Look AHEAD was a randomized CVD trial in 5,145 overweight/obese subjects with T2DM, comparing ILI (goal of ≥7% reduction in baseline weight) with a control arm of diabetes support and education (DSE). ILI participants were encouraged to consume vegetables, fruits and grain products low in sugar and fat. At baseline, median fiber intake was 17.9 g/d. Each 8.3 g/day higher fiber intake was associated with a 9.2% lower PAI-1 level (p=0.008); this association persisted after weight and fitness adjustments (p=0.03). Higher baseline intake of fruit (p=0.019) and high-fiber grain and cereal (p=0.029) were related to lower PAI-1 levels. Although successful in improving weight and physical fitness at 1-year, ILI in Look AHEAD resulted in small increases in fiber intake (4.1g/day, compared with -2.35 g/day with DSE), which were not related to PAI-1 change (p=0.34). Only 31.3% of ILI participants (39.8% of women; 19.1% of men) met daily fiber intake recommendations. Increasing fiber intake in overweight/obese individuals with diabetes interested in weight loss is challenging. Future studies evaluating changes in fiber consumption during weight loss interventions are warranted. PMID:25131348

    In this study we assess radiographic findings characteristic of mandibular 3rd molars that had required either routine or surgical extraction. X-ray findings relating to acute pericoronitis were also examined. The material was collected by investigating patient records and rotational panoramic radiographs of 20-year-old Finnish male conscripts (n = 738) treated during military service because of 3rd-molar-related problems. The follicle around the crown of mandibular 3rd molars with acute pericoronitis was enlarged in 19% of cases and in 13% of chronic symptom-free pericoronitis cases (not statistically significant difference). Mandibular 3rd molars extracted surgically were more often mesially inclined than those extracted routinely (61% vs. 23%; P pericoronitis [around 27% vs. 39% of the teeth routinely extracted (OR 0.5, 95% CI 0.3-0.8)]. In 86% of cases the space between 2nd molar and ramus of the mandible was narrower than the 3rd molar extracted surgically, whereas this was 62% in routine extraction cases (P < 0.001). We conclude that there are some typical 3rd-molar findings in rotational panoramic radiographs that show a need for surgical extraction.

    The term 'hemiconvulsion-hemiplegia-epilepsy syndrome' (HHE) was first used by Gastaut et al. to describe the se-quential combination of unilateral or predominantly unilateral clonic seizures (hemiconvulsion), occurring during the first 2 years of life, immediately followed by an ipsilateral flaccid hemiplegia lasting 7 or more days. In the following phase partial epileptic seizures occur. We report a case of HHE syndrome in a 3-year-old boy with partial seizures (hemiconvulsion lasting 15-30 minutes) followed by left hemiplegia and hyporeflexia. Magnetic resonance imaging showed diffuse and high signal hyperintensity of the whole right cerebral hemisphere. Diffusion-weighted images showed a reduction of the apparent diffusion coefficient in the subcortical region. Magnetic resonance arterio-graphy showed a narrow flow signal in the distal territory of the right middle cerebral artery. The authors emphasize the importance of neuroradiological findings in early diagnosis and in the follow-up of HHE syndrome.

    Full Text Available Background/Objective: Brest cancer is the second reason of mortality due to cancer in women and according to its high prevalence and psychosociophysical complications, immediate diagnosis is always under consideration. In most cases diagnosis of breast cancer in young women in reproductive ages is difficult. The objective of this study was report mammographic findings of breast cancer in women under 35 years old."nPatients and Methods: In this study the present files in storage room of radiology ward of Imam Reza, Qaem, and Omid Hospitals (1995-2004. In Mashad university of Medical sciences related to women under 35 years with breast cancer were assessed. Specific goals in this study were specification the clinical signs, mammographic findings, the pathology of breast cancer and also family history."nResults: A total of 2570 patients with breast cancer during 10 years period refered to these centers that 231 patients (9% were ≤35 years. Sixty two patients (51.3% had positive family history. The most common cancer according to the history was breast cancer in 30 cases (48.4%. The most common chief complain in these patients was a mass in 74 cases (80.4%.The most common mammographic pattern was mass with microcalcification in 37 cases (33.9%. Identifying a mass alone in mammography was seen in 17 cases (15.6%. The tumors were in the left breast in 114 cases (49%, and the most common site was supralateral quadrant (50.8%. The most common pathology was ductal carcinoma invasive in 200 cases (86.6%."nConclusion: Breast cancer in young women have poor prognosis. It may be difficult to detect breast cancer in mammography and the other modalities are usually helpful. Masses which discovered by patients themselves must be considered strictly and diagnostic procedures must be performed due to that, immediate treatment would be effective.

    Recent research has documented crack cocaine's increasing spread in Mexico, which is likely to contribute to the rapid transmission of HIV and other sexually transmitted infections (STIs). In Mexico, crack use is increasing most rapidly in vulnerable, hard-to-reach populations, where little is known about risk behaviors. This report aims to present baseline data regarding HIV and STI knowledge and testing prevalence from an innovative projection mapping HIV intervention, in which 3-D illusions, animation, and visual text graphics and sound are projected onto buildings with health messages that were designed to disrupt everyday life and connect with the target population. Fifty-eight men and women who used crack in the past month without receiving drug treatment were recruited and interviewed before the projection mapping intervention took place. Testing instruments included a sociodemographic assessment, drug use and treatment profile, HIV and STI knowledge questionnaires, and a sex and drug risk assessment. The mean scores for respondents on the HIV Knowledge Questionnaire (10.5 out of 18, 58.3%) and STD Knowledge Questionnaire (9.5 out of 27, 35.2%) were both low. Respondents also reported high rates of sexual risk behaviors, with 73% reporting never using a condom and 64% never being tested for HIV. This report provides a portrait of STI and HIV risk among a vulnerable population in Mexico City and the need for urgent interventions to prevent the spread of STIs and HIV. The associated projection mapping intervention will seek to increase HIV and STI knowledge and reduce risk in this hard-to-reach population.

    Background Weak grip strength (GS) is a key component of sarcopenia and frailty and a powerful predictor of mortality, morbidity and disability. Despite increasing interest in understanding GS across the lifespan, little is known about GS decline in the very old (aged ≥85). We examined trajectories of GS in very old adults and identified the determinants. Methods GS (kg) was measured four times over 5 years in 319 men and 526 women participating in the Newcastle 85+ Study. A weak GS sub-cohort was identified as having strength of ≤27 kg (men), and ≤16 kg (women) at baseline and follow-up. Mixed models were used to establish trajectories of GS and associated factors in all participants, men and women, and in those with weak GS. Results Men’s mean grip strength was 24.42 (SD = 6.77) kg, and women’s 13.23 (4.42) kg (p<0.001) at baseline, with mean absolute change of -5.27 (4.90) kg and -3.14 (3.41), respectively (p<0.001) by 5-year follow-up. In the time-only mixed model, men experienced linear annual decline in GS of -1.13 (0.8) kg (β (SE), p<0.001), whilst women’s decline although slower, accelerated by -0.06 (0.02) kg (p = 0.01) over time. In the saturated model, higher baseline physical activity, height, fat-free mass, better self-rated health, and not having arthritis in hand(s) were associated with stronger GS initially in both sexes. Annual GS decline in men and participants with weak GS who were highly physically active was slower by 0.95 and 0.52 kg, respectively compared with inactive counterparts. Conclusion Grip strength decline in the very old followed linear (men) and curvilinear (women) trends. High levels of physical activity were protective of GS loss in men (but not in women) and in those with weak GS. Thus maintaining muscle strength in later life is important to reduce the morbidity and mortality in the very old. PMID:27637107

    Dulaglutide (dula, LY2189265) is a once-weekly glucagon-like peptide-1 analog in development for the treatment of type 2 diabetes mellitus. An adaptive, dose-finding, inferentially seamless phase 2/3 study was designed to support the development of this novel diabetes therapeutic. The study is divided into two stages based on two randomization schemes: a Bayesian adaptive scheme (stage 1) and a fixed scheme (stage 2). Stage 1 of the trial employs an adaptive, dose-finding design to lead to a dula dose-selection decision or early study termination due to futility. If dose selection occurs, the study proceeds to stage 2 to allow continued evaluation of the selected dula doses. At completion, the entire study will serve as a confirmatory phase 3 trial. The final study design is discussed, along with specifics pertaining to the actual execution of this study and selected baseline characteristics of the participants.

    An epidemic of Mesoamerican Nephropathy (MeN) is killing thousands of agricultural workers along the Pacific coast of Central America, but the natural history and aetiology of the disease remain poorly understood. We have recently commenced a community-based longitudinal study to investigate Chronic Kidney Disease (CKD) in Nicaragua. Although logistically challenging, study designs of this type have the potential to provide important insights that other study designs cannot. In this paper we discuss the rationale for conducting this study and summarize the findings of the baseline visit. The baseline visit of the community-based cohort study was conducted in 9 communities in the North Western Nicaragua in October and November 2014. All of the young men, and a random sample of young women (aged 18-30) without a pre-existing diagnosis of CKD were invited to participate. Glomerular filtration rate (eGFR) was estimated with CKD-EPI equation, along with clinical measurements, questionnaires, biological and environmental samples to evaluate participants' exposures to proposed risk factors for MeN. We identified 520 young adults (286 males and 234 females) in the 9 different communities. Of these, 16 males with self-reported CKD and 5 females with diagnoses of either diabetes or hypertension were excluded from the study population. All remaining 270 men and 90 women, selected at random, were then invited to participate in the study; 350 (97%) agreed to participate. At baseline, 29 (11%) men and 1 (1%) woman had an eGFR <90 mL/min/1.73 m(2). Conducting a community based study of this type requires active the involvement of communities and commitment from local leaders. Furthermore, a research team with strong links to the area and broad understanding of the context of the problem being studied is essential. The key findings will arise from follow-up, but it is striking that 5% of males under aged 30 had to be excluded because of pre-existing kidney disease, and that

    Microfinance is the provision of financial services for the poor. Health program through microfinance has the potential to address several access barriers to health. We report the design and baseline findings of a multi-site non-randomized evaluation of the effect of a health program on the members of two microfinance organizations from Karnataka and Gujarat states of India. Villages identified for roll-out of health services with microfinance were pair-matched with microfinance only villages. A quantitative survey at inception and twelve months post health intervention compare the primary outcome (incidence of childhood diarrhea), and secondary outcome (place of last delivery, toilet at home, and out-of-pocket expenditure on treatment). At baseline, the intervention and comparison communities were similar except for out-of-pocket expenditure on health. Low reported use of toilet at home indicates the areas are heading towards a sanitation crisis. This should be an area of program priority for the microfinance organizations. While respondents primarily rely on their savings for meeting treatment expenditure, borrowing from friends, relatives, and money-lenders remains other important source of meeting treatment expenditure in the community. Programs need to prioritize steps to ensure awareness about national health insurance schemes, entitlement to increase service utilization, and developing additional health financing safety nets for financing outpatient care, that are responsible for majority of health-debt. Finally we discuss implications of such programs for national policy makers.

Methods A cluster randomized design with 12 housing sites as the primary sampling units was used: 6 sites were assigned to a "Peer-led plus Screening Access" (PL condition, and 6 were assigned to "Screening Access only" (SCR condition. Study-related outcomes were CRC screening, physical activity (measured as mean steps/day, and multivitamin use. Results At baseline (unweighted sample size = 1554, two-thirds self-reported that they were current with screening recommendations for CRC (corrected for medical records validation, prevalence was 52%, with half having received a colonoscopy (54%; 96% had health insurance. Mean steps per day was 5648 (se mean = 224, and on average 28% of the sample reported regular multivitamin use. Residents reported high levels of social support [mean = 4.40 (se = .03] and moderately extensive social networks [mean = 2.66 (se = .02]. Conclusion Few studies have conducted community-based studies in public housing communities; these data suggest areas for improvement and future opportunities for intervention development and dissemination. Findings from the randomized trial will determine the effectiveness of the intervention on our health-related outcomes as well as inform future avenues of research.

    This study examines the relationship between economic resources, psychosocial well-being, and educational preferences of AIDS-orphaned children in southern Uganda. We use baseline data from a sample of 1410 AIDS-orphaned children (defined as children who have lost one or both biological parents to AIDS) enrolled in the Bridges to the Future study, a National Institute of Child Health and Human Development (NICHD) funded study. Analyses from both bivariate and multiple regression analyses indicate the following: 1) despite the well-documented economic and psychosocial challenges AIDS-orphaned children face, many of these children have high educational plans and aspirations; 2) educational aspirations differ by orphanhood status (double orphan vs. single orphan); 3) regardless of orphanhood status, children report similar levels of psychosocial well-being; 4) high levels of family cohesion, positive perceptions of the future, school satisfaction, and lower levels of hopelessness (hopefulness) are associated with high educational aspirations; and 5) reported family economic resources at baseline, all seem to play a role in predicting children's educational preferences and psychosocial well-being. These findings suggest that the focus for care and support of orphaned children should not be limited to addressing their psychosocial needs. Addressing the economic needs of the households in which orphaned children live is equally important. Indeed, in the context of extreme poverty-in which most of the children represented in this study live-addressing structural factors, including poverty, may be a key driver in addressing their psychosocial functioning.

    We examined associations between the apolipoprotein E (APOE) ε4 allele and levels of performance and rates of change in cognition in late life taking incident dementia into account. The sample consisted of 482 nondemented individuals, aged 80 years and older at baseline, drawn from the OCTO twin study. A battery of 10 cognitive tests was administered at 5 occasions with measurements intervals of 2 years. We fitted hierarchical linear models with time specified as time to death and controlled for baseline age, sex, education, stroke, cardiovascular disease, hypertension, diabetes, and incident dementia. The ε4 allele was significantly associated with lower levels of performance or steeper rate of decline in all 7 memory tests. Largest effect sizes were found in tests of delayed recall and recognition memory. The effects of the APOE ε4 allele were, however, reduced to a nonsignificant level in all tests except 1 after accounting for incident dementia. The findings support the notion that the APOE ε4 allele is associated with substantial memory decline in very old age, but as expected, the effect is largely related to incident dementia.

    Full Text Available Neuroblastoma (NB is a common malignancy in children, but rarely occurs in adults. Accepted unfavorable prognostic factors include age over one year, low histological grade and advanced stage, MYCN amplification, chromosomal aberrations, elevations of neuron specific enolase and lactate dehydrogenase, and increased catecholamine metabolites in urine or serum. In adults, abdomen/retroperitoneum are the primary sites and in children the adrenal gland. We report a 38-year old civil servant who presented at our urology clinic on the 21st of December 2007 with a six month history of right flank dull pain which was worse on walking and relieved by rest, hypertension and a large right retroperitoneal mass. Tumor resection revealed a grade III NB. Chemotherapy using a combination of vincristine, adriamycin and cyclophosphamide was started. Follow-up showed regression of the mass initially with a relapse after patient absconded for three months. He resurfaced with new masses and he had a repeat chemotherapy with disappearance of the masses and is currently undergoing further treatment. To our knowledge this is the only report of NB in an adult registered so far in Nigeria and perhaps the whole of Africa. Currently, there are no standard treatment guidelines for patients with NB in adulthood. This study emphasizes the need for a standard treatment regime for adult onset neuroblastoma and its recognition as a possible differential in intra-abdominal mass in adults.

    Hypnotizability is associated with attentional characteristics whose neurophysiological bases are still under debate. Aim of the study was the assessment of possible hypnotizability-related differences in blink reflex (BR) which has a nociceptive component, is sensitive to attentional-emotional traits and states and is modulated by the brain dopamine content. In 10 high (highs) and 10 low hypnotizable participants (lows) BR was induced by electrical nociceptive stimulation of the right supraorbital nerve in the absence (noW) and in the presence of a visual cue preceding the electrical stimulation by 0.1ms (W01) and by 1ms (W1). The studied variables were: the amplitude of BR components (R1, R2, R3), the amplitude of the quick change (TO) of heart rate ("turbulence") induced by stimulation and its recovery slope (TS), the role of the Behavioral Inhibition/Activation System (BIS/BAS) in the variability BR and cardiac turbulence. Repeated measures ANOVA did not show any significant difference between highs and lows in blink reflex. TO indicated stimulation related HR increase in highs and decrease in lows, TS was larger in highs. BIS and BAS accounted for the warning effects on the BR amplitude and modulated the hypnotizability and warning effects on TO and TS. Findings do not support dopamine based hypnotizability-related attentional abilities. In contrast, they indicate that hypnotizability modulates the short-lasting cardiac response to electrical nociceptive stimulation.

    Introduction: Cartilaginous nasal septal agenesis is a rare finding. In fact, just one case has been reported to have congenital agenesis of all nasal cartilages in a 6-year-old child by Bakhshaee et al. The literature review shows another case that was reported by Ozek et al in Turkey, where they reported a case of total nasal agenesis that was associated with Tessier no. 30. We could not find a similar case in the literature where only agenesis of the nasal cartilaginous septum was present. Methods/Case Report: This is a case report of a 5-year-old child presenting to our clinic with agenesis of his nasal septum and attenuation of the upper and lower lateral cartilages. His parents were seeking a corrective procedure to improve the shape of his nose. He was a male child with a right unilateral cleft lip and palate that were corrected surgically in 2009 (lip repair) and 2010 (palate repair), respectively. Results: On postoperative week 3, the patient's mother brought him to the emergency department with a history of falling on his face while playing at home. Examination revealed swelling of the nose but no breathing difficulties. He still had an acceptable augmented nose but with sings of deviation and collapse. Discussion: We report this case to find an answer to how such cases can be approached in the future in terms of the surgical intervention required and to study the options of redoing such cases.

    Full Text Available There is a paucity of data related to sports injuries, concussions, and computerized neurocognitive testing (CNT among very young athletes playing sports in recreational settings. The purpose of this study was to report baseline CNT results among male and female children, ages 5–11, playing sports in Hillsborough County, Florida using ImPACT Pediatric, which is specifically designed for this population. Data were collected from 2016 to 2017. The results show that 657 baseline tests were conducted and t-tests and linear regression were used to assess mean significant differences in composite scores with sex and age. Results showed that females scored better on visual memory and in general as age increased, baseline scores improved. The results can be used to build further studies on the use of CNT in recreational settings and their role in concussion treatment, management, and interventions.

Hemorrhagic transformation, dense middle cerebral artery sign, mass effect, and cerebral edema at day 10 were not independently...... associated with baseline BP. Conclusion-Although high baseline BP is independently associated with a poor outcome after stroke, this was not shown to be through an association with increased hemorrhagic transformation, cerebral edema, or mass effect; trial design may be suboptimal to detect this. Higher SBP...

    Full Text Available BACKGROUND: The demographic transition in South Asia coupled with unplanned urbanization and lifestyle changes are increasing the burden of non-communicable disease (NCD where infectious diseases are still highly prevalent. The true magnitude and impact of this double burden of disease, although predicted to be immense, is largely unknown due to the absence of recent, population-based longitudinal data. The present study was designed as a unique 'Framingham-like' Pakistan cohort with the objective of measuring the prevalence and risk factors for hypertension, obesity, diabetes, coronary artery disease and hepatitis B and C infection in a multi-ethnic, middle to low income population of Karachi, Pakistan. METHODS: We selected two administrative areas from a private charitable hospital's catchment population for enrolment of a random selection of cohort households in Karachi, Pakistan. A baseline survey measured the prevalence and risk factors for hypertension, obesity, diabetes, coronary artery disease and hepatitis B and C infection. RESULTS: Six hundred and sixty-seven households were enrolled between March 2010 and August 2011. A majority of households lived in permanent structures (85% with access to basic utilities (77% and sanitation facilities (98% but limited access to clean drinking water (68%. Households had high ownership of communication technologies in the form of cable television (69% and mobile phones (83%. Risk factors for NCD, such as tobacco use (45%, overweight (20%, abdominal obesity (53%, hypertension (18%, diabetes (8% and pre-diabetes (40% were high. At the same time, infectious diseases such as hepatitis B (24% and hepatitis C (8% were prevalent in this population. CONCLUSION: Our findings highlight the need to monitor risk factors and disease trends through longitudinal research in high-burden transition communities in the context of rapid urbanization and changing lifestyles. They also demonstrate the urgency of public

    Full Text Available Female sex workers (FSW are often the focus of primary HIV prevention efforts. However, little attention has been paid to the prevention, treatment, and care needs of FSW living with HIV. Based on formative research, we developed an integrated model to promote prevention and care for FSW living with HIV in Santo Domingo, Dominican Republic, including (1 individual counseling and education; (2 peer navigation; (3 clinical provider training; and (4 community mobilization. We enrolled 268 FSW living with HIV into the intervention and conducted socio-behavioral surveys, sexually transmitted infection (STI testing, and viral load (VL assessments. We used multivariate logistic regression to identify behavioral and socio-demographic factors associated with detectable VL (>50 copies/mL and STI prevalence. Over half of all participants (51.9% had a detectable VL, even though most received HIV-related care in the last 6 months (85.1% and were currently on anti-retroviral treatment (ART (72.4%. Factors positively associated with a detectable VL included being 18-35 years of age (Adjusted Odds Ratio [AOR] 2.46, 95% CI 1.31-4.60, having ever used drugs (AOR 2.34, 95% CI 1.14-4.79, and having ever interrupted ART (AOR 3.09, 95% CI 1.44-6.59. Factors protective against having a detectable VL included being single (AOR 0.45, 95% 0.20-0.98 and being currently on ART (AOR 0.17, 95% CI 0.07-0.41. Nearly one-quarter (23.1% had an STI, which was associated with being single (AOR 3.21, 95% CI 1.27-8.11 and using drugs in the last 6 months (AOR 3.54, 95% CI 1.32-9.45. Being on ART was protective against STI (AOR 0.51, 95% CI 0.26-1.00. Baseline findings indicate significant barriers to VL suppression and STI prevention among FSW living with HIV and highlight gaps in the continuum of HIV care and treatment. These findings have important implications for both the individual health of FSW and population-level HIV transmission dynamics.

  13. Baseline rationing

    Hougaard, Jens Leth; Moreno-Ternero, Juan D.; Østerdal, Lars Peter Raahave

    The standard problem of adjudicating conflicting claims describes a situation in which a given amount of a divisible good has to be allocated among agents who hold claims against it exceeding the available amount. This paper considers more general rationing problems in which, in addition to claims......, there exist baselines (to be interpreted as objective entitlements, ideal targets, or past consumption) that might play an important role in the allocation process. The model we present is able to accommodate real-life rationing situations, ranging from resource allocation in the public health care sector...... to international protocols for the reduction of greenhouse emissions, or water distribution in drought periods. We define a family of allocation methods for such general rationing problems - called baseline rationing rules - and provide an axiomatic characterization for it. Any baseline rationing rule within...

    This paper reports on a population-based sample survey of 2,289 children aged less than five years (under-five children) conducted in 2000 as a baseline for the Bangladesh component of the Multi-country Evaluation (MCE) of the Integrated Management of Childhood Illness strategy. Of interest were rates and differentials by sex and socioeconomic status for three aspects of child health in rural Bangladesh: morbidity and hospitalizations, including severity of illness; care-seeking for childhood illness; and home-care for illness. The survey was carried out among a population of about 380,000 in Matlab upazila (subdistrict). Generic MCE Household Survey tools were adapted, translated, and pretested. Trained interviewers conducted the survey in the study areas. In total, 2,289 under-five children were included in the survey. Results showed a very high prevalence of illness among Bangladeshi children, with over two-thirds reported to have had at least one illness during the two weeks preceding the survey. Most sick children in this population had multiple symptoms, suggesting that the use of the IMCI clinical guidelines will lead to improved quality of care. Contrary to expectations, there were no significant differences in the prevalence of illness either by sex or by socioeconomic status. About one-third of the children with a reported illness did not receive any care outside the home. Of those for whom outside care was sought, 42% were taken to a village doctor. Only 8% were taken to an appropriate provider, i.e. a health facility, a hospital, a doctor, a paramedic, or a community-based health worker. Poorer children than less-poor children were less likely to be taken to an appropriate healthcare provider. The findings indicated that children with severe illness in the least poor households were three times more likely to seek care from a trained provider than children in the poorest households. Any evidence of gender inequities in child healthcare, either in terms

    Little research has examined the effect of water consumption on cognition in children. We examined whether drinking water improves performance from baseline to test in twenty-three 6-7-year-old children. There were significant interactions between time of test and water group (water/no water), with improvements in the water group on thirst and happiness ratings, visual attention and visual search, but not visual memory or visuomotor performance. These results indicate that even under conditions of mild dehydration, not as a result of exercise, intentional water deprivation or heat exposure, children's cognitive performance can be improved by having a drink of water.

  17. Clinical, Bacteriological, and Histopathological Findings of a Testicular Fibrosis in a 6-Year-Old Lusitano Stallion

    2012-01-01

    Full Text Available A 6-year-old Lusitano stallion was referred to our centre due to an enlarged left testicle. Anamnesis indicated that the stallion had a chronic hypertrophy of the left testicle, with no apparent ill effect on work (dressage training or semen production. Prolonged use of anti-inflammatory drugs (NSAIDs and antibiotics were probable. Upon examination of the animal, it was found that clinical signs were compatible with chronic testicular degeneration or fibrosis. Ultrasound scanning did not evidence the exuberant macroscopic lesions seen upon hemicastration of the left testicle, but it showed in the left spermatic cord a conspicuous absence of the typical hypoechogenic areas representing the pampiniform plexus. Swabbing of the penis, prepuce, and distal urethra resulted in the isolation of Rhodococcus equi and Corynebacterium spp. However, histopathological examination did not support infectious orchitis as cause of the lesions and no bacterial growth was obtained from swabbing of the parenchyma in the excised testicle. Histopathological findings were compatible with chronic orchitis with fibrosis and necrosis, probably secondary to ischemia of the testicular parenchyma. After hemi-castration, the stallion resumed semen production at acceptable levels.

    This descriptive, cross-sectional analysis evaluated the impact of baseline characteristics on health-related quality of life (HR-QoL) at different stages of multiple myeloma (MM). The bortezomib clinical-trial programme evaluated HR-QoL early and consistently, producing a large multi-study dataset. Baseline data, captured using the European Organization for Research and Treatment of Cancer (EORTC) quality-of-life questionnaire (QLQ-C30), were pooled from six bortezomib randomized trials conducted in different disease-stage categories: 'New' (previously untreated; n = 753), 'Early' (1-3 prior therapies; n = 1569) and 'Late' (≥4 prior therapies; n = 239) disease. Mean EORTC global health scores were similar across the three stages. Unexpectedly, emotional, physical and role functioning were higher in the later stages, indicating better perceived health. Symptom scores, including pain, were largely similar or lower in the later versus earlier stages, signifying a lower symptom burden/better symptom control with more advanced disease. Notable variation in HR-QoL was observed by age and clinical parameters within and across stages. Multivariate modelling indicated that opioid use and performance status were key factors driving overall HR-QoL across stages. Using an age-restricted analysis, transplant eligibility had little impact on HR-QoL in New disease patients. Thus, changes in HR-QoL over the treatment course of MM are complex and impacted by baseline factors. A prospective observational international inception cohort study that captures key clinical, HR-QoL and demographic characteristics, along with safety and supportive care information, is needed. © 2016 The Authors.

    There is a paucity of randomized controlled trials (RCTs) to evaluate models of palliative care. Although interventions vary, all have faced a variety of methodological challenges including adequate recruitment, missing data, and contamination of the control group. We describe the ENABLE II intervention, methods, and sample baseline characteristics to increase intervention and methodological transparency, and to describe our solutions to selected methodological issues. Half of the participants recruited from our rural U.S. comprehensive cancer center and affiliated clinics were randomly assigned to a phone-based, nurse-led educational, care coordination palliative care intervention model. Intervention services were provided to half of the participants weekly for the first month and then monthly until death, including bereavement follow-up call to the caregiver. The other half of the participants were assigned to care as usual. Symptoms, quality of life, mood, and functional status were assessed every 3 months until death. Baseline data of 279 participants were similar to normative samples. Solutions to methodological challenges of recruitment, missing data, and "usual care" control group contamination are described. It is feasible to overcome many of the methodological challenges to conducting a rigorous palliative care RCT.

    Little is known about the epidemiology of human papillomavirus (HPV) in Italy before the age of 25. At the European Institute of Oncology, a prospective observational study on cervical HPV infection in 18-year-old women undergoing quadrivalent HPV vaccination is ongoing. At the first visit before vaccination, all the young women answered an epidemiological questionnaire, and then, the presence of high-risk HPV (hrHPV) was tested. Samples positive for hrHPV were genotyped. Liquid-based cytology was done only to women declaring not to be virgins. Any positivity at cytology or HPV testing was completed with colposcopy and eventually biopsies. Seven hundred and thirty women were enrolled. Two hundred sixty-six women were virgins; 7 (2.6%) of these resulted positive to hrHPV: 1 had HPV16 and CP6108, whereas the other 6 resulted negative at genotyping. Of the 464 nonvirgins, 61 (13.1%) were HPV positive: 19 had HPV16, 4 were positive to HPV18 with other hrHPVs, 25 to other hrHPVs, 7 to low-risk HPV, whereas 13 resulted negative at genotyping. HPV positivity was significantly associated to both smoking and having more than 3 partners. Cervical cytology was negative in 433 cases (93.3%), ASC-US in 10 cases (2.2%), low-grade squamous intraepithelial lesion in 20 cases (4.3%), and ASC-H in 1 case (0.2%). No CIN2+ was identified. Overall, we found a low positivity to HPV in this population; however, the rate of HPV positivity was significantly related to smoking and sexual life. The cytology result low-grade squamous intraepithelial lesion was more frequent than in the screening population, whereas no CIN2+ was identified, confirming the indication to avoid screening at this age.

    The supply of information and communication is becoming continuously more focused on the Internet. While the age groups up to 64 years have shown a vast increase in the use of the Internet since 1997, intensive use of the Internet by age groups above 64 years lags behind and this is not only the case in Switzerland. Against this background and an interest in finding out more about Internet (non)use of older people, two representative surveys were conducted in Switzerland, one in 2009 and another one in 2014. The data used were acquired throughout Switzerland via a standardized telephone survey. The random sample (2014) consisted of 1037 people aged between 65 and 100 years old. Although the digital divide between the age groups has lessened over the past years, only 55.7 % of the elderly people interviewed were using the Internet in the autumn of 2014. Internet usage differs greatly between age groups. Resources such as education, income and health positively impact actual use of the Internet. Additionally, recommendations from a person's social environment, as well as an affinity for technology and a personal benefit assessment have a positive impact on Internet usage. In particular, security concerns and difficulties of use were mentioned as predominant reasons for the non-use of the Internet. Some of the people questioned felt excluded from society because they did not use the Internet. Internet usage among elderly people depends on individual and social resources, as well as on general attitude towards technology and personal benefit expectations. The exclusion of today's elderly "offliners" should be avoided, even if the digital divide will decrease in the future.

  3. Randomised controlled trial of an automated, interactive telephone intervention (TLC Diabetes) to improve type 2 diabetes management: baseline findings and six-month outcomes

    2012-01-01

    Background Effective self-management of diabetes is essential for the reduction of diabetes-related complications, as global rates of diabetes escalate. Methods Randomised controlled trial. Adults with type 2 diabetes (n = 120), with HbA1c greater than or equal to 7.5 %, were randomly allocated (4 × 4 block randomised block design) to receive an automated, interactive telephone-delivered management intervention or usual routine care. Baseline sociodemographic, behavioural and medical history data were collected by self-administered questionnaires and biological data were obtained during hospital appointments. Health-related quality of life (HRQL) was measured using the SF-36. Results The mean age of participants was 57.4 (SD 8.3), 63% of whom were male. There were no differences in demographic, socioeconomic and behavioural variables between the study arms at baseline. Over the six-month period from baseline, participants receiving the Australian TLC (Telephone-Linked Care) Diabetes program showed a 0.8% decrease in geometric mean HbA1c from 8.7% to 7.9%, compared with a 0.2% HbA1c reduction (8.9% to 8.7%) in the usual care arm (p = 0.002). There was also a significant improvement in mental HRQL, with a mean increase of 1.9 in the intervention arm, while the usual care arm decreased by 0.8 (p = 0.007). No significant improvements in physical HRQL were observed. Conclusions These analyses indicate the efficacy of the Australian TLC Diabetes program with clinically significant post-intervention improvements in both glycaemic control and mental HRQL. These observed improvements, if supported and maintained by an ongoing program such as this, could significantly reduce diabetes-related complications in the longer term. Given the accessibility and feasibility of this kind of program, it has strong potential for providing effective, ongoing support to many individuals with diabetes in the future. PMID:22857017

    Violence against women is driven by gender norms that normalize and justify gender inequality and violence. Gender norms are substantially shaped during adolescence. Programs offered through schools offer an opportunity to influence gender attitudes toward gender equity if we understand these to be partly shaped by peers and the school environment. We present an analysis of the baseline research conducted for a randomized controlled trial with 1752 grade 6 boys and girls and their attitudes toward gender roles, VAWG, and associated factors. We used baseline data from a  cluster randomised control study. Interviews were conducted in 40 public schools in Hyderabad, with 25-65 children per school. Questions were asked about attitudes toward gender roles, peer-to-peer perpetration, and victimization experiences, and family life, including father- or in-law-to- mother violence and food security. Multiple regression models were built of factors associated with gender attitudes for boys and girls. Our result have shown youth attitudes endorsing patriarchal gender beliefs were higher for boys, compared to girls. The multiple regression model showed that for boys, patriarchal gender attitudes were positively associated with hunger, depression, being promised already in marriage, and being a victim and/or perpetrator of peer violence. For girls gender attitudes were associated with hunger, experiencing corporal punishment at home, and being a perpetrator (for some, and victim) of peer violence. Youth patriarchal attitudes are closely related to their experience of violence at school and for girl's physical punishment, at home and for boys being promised in early marriage. We suggest that these variables are indicators of gender norms among peers and in the family. The significance of peer norms is that it provides the possibility that school-based interventions which work with school peers have the potential to positively impact youth patriarchal gender attitudes and foster

    Zimbabwe faces an acute generalized HIV/AIDS epidemic combined with rapidly deteriorating economic and political conditions, under which levels of domestic violence are on the rise. We aimed to determine possible demographic and behavioral factors associated with physical domestic violence in a rural setting in order to better inform both national and local domestic violence and HIV prevention policies. Using the Project Accept baseline data set, we selected demographic, socio-economic, and behavioral variables that might be associated with physical domestic violence based on a review of the literature. Univariate and multivariate analyses were carried out, and odds ratios (OR) were computed using logistic regression. Women reporting physical domestic violence were significantly more likely to report (i) a history of childhood domestic violence (OR=2.96, Peconomic status as measured by type of homestead (OR=1.4, P=0.04) than women who reported no experience of physical domestic violence. Married women were less likely to experience physical domestic violence than unmarried women (OR=0.65, P=0.011). Women at greatest risk of domestic violence include those with a personal history of violence or sexual abuse, multiple lifetime partners, and low or medium socio-economic status. Risk assessments and joint interventions for both domestic violence reduction and HIV prevention should target these population groups, which are effective both on the public health and global heath diplomacy levels.

    Full Text Available Zimbabwe faces an acute generalized HIV/AIDS epidemic combined with rapidly deteriorating economic and political conditions, under which levels of domestic violence are on the rise. We aimed to determine possible demographic and behavioral factors associated with physical domestic violence in a rural setting in order to better inform both national and local domestic violence and HIV prevention policies. Using the Project Accept baseline data set, we selected demographic, socio-economic, and behavioral variables that might be associated with physical domestic violence based on a review of the literature. Univariate and multivariate analyses were carried out, and odds ratios (OR were computed using logistic regression. Women reporting physical domestic violence were significantly more likely to report (i a history of childhood domestic violence (OR=2.96, P<0.001, (ii two or more lifetime partners (OR=1.94, P<0.001, (iii some form of sexual abuse as a child (OR=1.82, not significant, and (iv low or medium socio-economic status as measured by type of homestead (OR=1.4, P=0.04 than women who reported no experience of physical domestic violence. Married women were less likely to experience physical domestic violence than unmarried women (OR=0.65, P=0.011. Women at greatest risk of domestic violence include those with a personal history of violence or sexual abuse, multiple lifetime partners, and low or medium socio-economic status.

Although it is the most common congenital abnormality of the gastrointestinal tract, diagnosing and deciding on intervention is often a matter of debate when it presents asymptomatically. A 60-year-old man with an umbilical hernia presented to our institution for elective surgery. A Meckel’s diverticulum was incidentally discovered perioperatively and removed. Although the mortality and risk of complications are low, the surgical team in this case decided to remove the diverticulum to prevent any possible complications from occurring in the future due to its presence.Keywords: Meckel’s diverticulum, umbilical hernia, surgery

    To compare dietary intake in 1-year-old infants and their parents between families with high and low obesity risk, and to explore associations between infant dietary intake and relative weight. Baseline analyses of 1-year-old infants (n = 193) and their parents participating in a longitudinal obesity intervention (Early STOPP) were carried out. Dietary intake and diet quality indicators were compared between high- and low-risk families, where obesity risk was based on parental weight status. The odds for high diet quality in relation to parental diet quality were determined. Associations between measured infant relative weight and dietary intake were examined adjusting for obesity risk, socio-demographics, and infant feeding. Infant dietary intake did not differ between high- and low-risk families. The parents in high-risk families consumed soft drinks, French fries, and low-fat spread more frequently, and fish and fruits less frequently (p intake of vegetables and fish increased the odds for children being consumers of vegetables (OR 1.7; 95 % CI 1.0-2.9) and fish, respectively (OR 2.5; 95 % CI 1.4-4.4). Infant relative weight was weakly associated with a high intake of milk cereal drink (r = 0.15; p intake, obesity risk, or early feeding patterns. At the age of one, dietary intake in infants is not associated with family obesity risk, nor with parental obesogenic food intake. Milk cereal drink consumption but no other infant dietary marker reflects relative weight at this young age.

    African American women report high rates of physical inactivity and related health disparities. In our previous formative research, we conducted a series of qualitative assessments to examine physical activity barriers and intervention preferences among African American women in the Deep South. These data were used to inform a 12-month Home-based, Individually-tailored Physical activity Print (HIPP) intervention, which is currently being evaluated against a wellness contact control condition among 84 post-menopausal African American women residing in the metropolitan area of Birmingham, Alabama. This paper reports the rationale, design and baseline findings of the HIPP trial. The accrued participants had an average age of 57 (SD= 4.7), a BMI of 32.1 kg/m2 (SD=5.16) with more than half (55%) having a college education and an annual household income under $50,000 (53.6%). At baseline, participants reported an average of 41.5 minutes/week (SD=49.7) of moderate intensity physical activity, and 94.1% were in the contemplation or preparation stages of readiness for physical activity. While social support for exercise from friends and family was low, baseline levels of self-efficacy, cognitive and behavioral processes of change, decisional balance, outcome expectations, and enjoyment appeared promising. Baseline data indicated high rates of obesity and low levels of physical activity, providing strong evidence of need for intervention. Moreover, scores on psychosocial measures suggested that such efforts may be well received. This line of research in technology-based approaches for promoting physical activity in African American women in the Deep South has great potential to address health disparities and impact public health.

    2007-06-01

    This is a case of a 29-year-old man with a 6 year history of sleep-related eating disorder (SRED) that occurred with partial consciousness on a nightly basis. His family or wife witnessed up to 5 episodes every night, with each eating episode lasting 8-16 minutes. Polysomnography documented 4 episodes of sleep-related eating arising from stage 2 Non-REM sleep, when he consumed cookies that he had brought to the sleep lab that night. While eating, his EEG remained in stage 2 sleep or else was a wakeful EEG, and the eating episodes lasted for a mean 13.3 minutes. There was no epileptiform EEG activity during the polysomnogrphic study with a seizure montage and fast paper speed. Therapy with clonazepam, 0.5 mg bedtime, did not control the nocturnal eating. The patient tried to limit access to food in his home before bedtime, and this had modest benefit. This case of SRED has both typical and atypical features, which are discussed.

    Epidemiological studies have shown that a number of nutrients are associated with better physical performance. However, little is still known about the role of the whole diet, particularly a healthy Nordic diet, in relation to physical performance. Therefore, we examined whether a healthy Nordic diet was associated with measures of physical performance 10 years later. We studied 1072 participants from the Helsinki Birth Cohort Study. Participants' diet was assessed using a validated 128-item FFQ at the mean age of 61 years, and a priori-defined Nordic diet score (NDS) was calculated. The score included Nordic fruits and berries, vegetables, cereals, PUFA:SFA and trans-fatty acids ratio, low-fat milk, fish, red and processed meat, total fat and alcohol. At the mean age of 71 years, participants' physical performance was measured using the Senior Fitness Test (SFT), and an overall SFT score was calculated. Women in the highest fourth of the NDS had on average 5 points higher SFT score compared with those in the lowest fourth (P for trend 0·005). No such association was observed in men. Women with the highest score had 17% better result in the 6-min walk test, 16% better arm curl and 20% better chair stand results compared with those with the lowest score (all P valuesdiet was associated with better overall physical performance among women and might help decrease the risk of disability in old age.

    Increasing numbers of researchers are finding that loneliness is a significant risk factor for morbidity and mortality, and several variables have been found to be closely related to the experience of loneliness among elders. However, much of the research has focused on the general older population, with no research to date focusing on minority populations. The objective of this study was to determine the prevalence and the correlates of loneliness among a community-dwelling older Mexican American population. This study used a three-item loneliness scale to determine the prevalence of loneliness. Pearson's correlation and linear regression analyses were used to determine the cross-sectional association between sociodemographic, interpersonal relationship and health variables with the scale. Data used came from the most recent wave (2011) of the Hispanic Established Populations for the Epidemiological Study of the Elderly (H-EPESE). A total of 873 Mexican Americans completed the loneliness scale. The age range was from 80 to 102, with a majority (65%) female. The mean score on the scale was 4.05 (range 3-9), indicating relatively low levels of loneliness. Regression results indicate that depressive symptoms, cognitive status, and living alone were significantly associated with higher loneliness scores. Being married and having a confidante were significantly associated with lower loneliness. Age, number of close relatives and frequency of contact were not associated with loneliness. Findings suggest that among community-dwelling Mexican American older adults, loneliness has multiple determinants. Loneliness is a significant public health topic and clinicians should be aware of the various factors that can affect loneliness.

    Health in adulthood is in part a consequence of development and growth taking place during sensitive periods in early life. It has not been explored previously whether early growth is associated with physical performance in old age from a life course perspective taking into account health-related behavior, biological risk factors, and early life experiences. At a mean age of 71 years, physical performance was assessed using the Senior Fitness Test (SFT) in 1078 individuals belonging to the Helsinki Birth Cohort Study. We used multiple linear regression analysis to assess the association between the SFT physical fitness scores and individual life course measurements. Several adult characteristics were associated with physical performance including socioeconomic status, lifestyle factors, and adult anthropometry. Higher birth weight and length were associated with better physical performance, even after adjusting for potential confounders (all p values old age was found for adult body fat percentage. However, prenatal growth was independently associated with physical performance seven decades later. These findings suggest that physical performance in old age is at least partly programmed in early life.

    Introduction Falls are common in older people and increase in prevalence with advancing old age. There is limited knowledge about their impact in those aged 85 years and older, the fastest growing age group of the population. We investigated the prevalence and impact of falls, and the overlap between falls, dizziness and blackouts, in a population-based sample of 85 year olds. Methods Design: Cross-sectional analysis of baseline data from Newcastle 85+ Cohort Study. Setting: Primary care, North-East England. Participants: 816 men and women aged 85 years. Measurements: Structured interview with research nurse. Cost-consequence analysis of fall-related healthcare costs. Results Over 38% (313/816) of participants had fallen at least once in the previous 12 months and of these: 10.6% (33/312) sustained a fracture, 30.1% (94/312) attended an emergency department, and 12.8% (40/312) were admitted to hospital. Only 37.2% (115/309) of fallers had specifically discussed their falls problem with their general practitioner and only 12.7% (39/308) had seen a falls specialist. The average annual healthcare cost per faller was estimated at £202 (inter-quartile range £174–£231) or US$329 ($284–$377). ‘Worry about falling’ was experienced by 42.0% (128/305) of fallers, ‘loss of confidence’ by 40.0% (122/305), and ‘going out less often’ by 25.9% (79/305); each was significantly more common in women, odds ratios (95% confidence interval) for women: men of 2.63 (1.45–4.55), 4.00 (2.27–7.14), and 2.86 (1.54–5.56) respectively. Dizziness and blackouts were reported by 40.0% (318/796) and 6.4% (52/808) of participants respectively. There was marked overlap in the report of falls, dizziness and blackouts. Conclusions Falls in 85 year olds are very common, associated with considerable psychological and physical morbidity, and have high impact on healthcare services. Wider use of fall prevention services is needed. Significant expansion in acute and preventative

    Full Text Available Background: Precursor T-cell acute lymphoblastic leukemia (pre-T-ALL may cause ocular pathologies such as cotton-wool spots, retinal hemorrhage, and less commonly, retinal detachment or leukemic infiltration of the retina itself. However, these findings are typically accompanied by the pathognomonic hematological signs of acute leukemia. CasePresentation: In this case report and review of the literature, we describe a particularly unusual case of a 25-year-old man who presented to our hospital with bilateral exudative retinal detachments associated with posterior pole thickening without any hematological or neurological findings. The patient, who had a history of previously treated pre-T-ALL in complete remission, was found to have leukemia cell infiltration on retinal biopsy. Conclusion: Our case underscores the fact that the ophthalmologist may be the first provider to detect the relapse of previously treated leukemia, and that ophthalmic evaluation is critical for detecting malignant ocular infiltrates.

    Objective: To describe the general findings of lymphoma and their histological patterns in patients less than 20 years old. Materials And Methods: Twenty-two cases (16 male and 6 female, mean age 11.5 years) from the digital archive of computed tomography at the Cancer Control Center of Hospital Universitario Pedro Ernesto - Universidade do Estado do Rio de Janeiro, Rio de Janeiro, RJ, Brazil, were retrospectively analyzed in the period between March 2003 and July 2005. Of these 22 cases, 12 were Hodgkin's and 10 were non-Hodgkin's. Results: Overall, mediastinal lymphadenomegaly was the most frequent finding (59%), with predominance in the Hodgkin's subgroup (75%), followed by hepatosplenomegaly (50%) and cervical and retroperitoneal lymphadenomegaly (27.3%). The Hodgkin's subgroup presented a prevalence of lymphadenopathy, in many lymph node chains, followed by hepatosplenomegaly (50%). One case was found with unilateral tonsillar mass, pulmonary ground-glass opacities, and renal nodules. In the non-Hodgkin's subgroup, the disease was predominantly extranodal, characterized by hepatosplenomegaly (50%), thickening of the intestinal wall (40%), pleural effusion (30%), pulmonary nodule (20%), ascites (10%), pericardial effusion (10%) and mixed bone lesions (10%). Conclusion: Computed tomography is an extremely useful method for detection, staging and follow-up of lymphomas, with alert findings like mediastinal lymphadenopathy, hepatosplenomegaly, unilateral tonsillar mass and thickening of intestinal wall.

    This article aims to report the main clinical aspects, cone beam computed tomography (CBCT) findings, and conservative oral rehabilitation in a child born from a consanguineous marriage who presented with Hallermann-Streiff syndrome (HSS) and generalized odontodysplasia. A 5-year-old girl presented with a diagnosis of HSS for oral evaluation. Radiographically, all teeth showed wide pulp chambers and roots with thin dentinal walls and open apices, resembling ghost teeth and indicating a diagnosis of odontodysplasia. Oral rehabilitation consisted of partial dentures that were regularly adjusted to conform the device with the pattern of growth and development of the child. CBCT scan provided great insight into HSS, allowing a detailed view of the morphologic aspects and associated trabecular bone pattern. Treatment of these 2 rare conditions in young children must consider the stage of growth and development. Although extremely rare in HSS, odontodysplasia should be investigated and conservatively managed in young children.

    The aim of this study was to investigate the prevalence of developmental problems and relationship with sociodemographic variables in a community sample of young children. Participants included 1000 children (558 males, 442 females, age range 1-48 months, mean 18.4 months, SD 7.8 months). Children were referred generally by their parents for developmental evaluation and consultation in response to a public announcement in a district area in Istanbul, Turkey. An interview form and the Denver Developmental Screening Test II (DDST) were used for sociodemographic data and developmental evaluation. The χ(2) test and Pearson's correlation test were used for data analysis. Seven hundred forty-one out of 1000 children (74.1%) had normal, 140 (14%) had risky, and 119 (11.9%) had abnormal findings on the DDST results. The probability of abnormal findings on the DDST results was significantly higher in males (p=0.003), the 2-4-year-old group (p0.05). Sociodemographic factors have a noteworthy impact on development. Determining these factors is important especially during the first years of life.

    Finding a sense of home for international migrants is challenging. It is even more so for older adults who migrate to a foreign country later in life to follow their adult children. This study examines Chinese immigrant elders' report of their sense of home and life-satisfaction. Based on 21 intensive interviews and107 surveys with elderly immigrants of Chinese descent, this research finds that a comfortable living condition in a natural and built environment contribute to Chinese elders' narrative of a sense of home. The lack of English language, however, makes immigrant Chinese elders feel very unsettled. Being together with children and having good social benefits are major pull factors that contribute to immigrant elders' decision to settle down in a foreign country. Those who report a stronger sense of home tend to report a higher level of life satisfaction. In conclusion, the authors argue that immigrant elders are defining their sense of home with a greater sense of independence from their adult children. Favorable social policies toward older adults, such as Medicare, Medicaid, low income housing, and social services, are important factors that make older immigrants feel a sense of home in a foreign land, although the inability to communicate is a barrier to a complete sense of home for transnational migrants in old age.

    A treat to target (T2T) approach to management has become the standard of care for patients with rheumatoid arthritis (RA). While consensus T2T recommendations call for patient involvement in the treatment process, the targets commonly used to drive therapeutic decisions involve limited patient input. A pilot study was developed to explore whether the Patient-Reported Outcomes Measurement Information System (PROMIS) could add value to the T2T approach by providing a way to bring patient goals into the process. We report here the baseline data from this study. RA patients from an academic rheumatology practice were recruited to participate in this 1-year study. Patients were asked to complete PROMIS computer-assisted testing at quarterly visits during the year. At baseline, they were asked to identify the PROMIS domain (Pain Interference, Fatigue, Depression, Physical Function, and Social Function) that felt most important to their quality of life. They were then asked to select five representative items from this domain, to be followed through the year. Complete baseline data was available for 119 patients. Most selected Physical Function (39%) or Pain Interference (37%) as their highest priority PROMIS domain. Sixty percent ranked Depression as their lowest priority domain. Younger patients more frequently prioritized Social Function, while older patients more frequently prioritized Fatigue. The incorporation of PROMIS questionnaires into routine clinic visits is a feasible mechanism for incorporating patient preferences into a T2T approach to managing RA.

    Full Text Available Abstract Background Compared to females, males experience higher rates of chronic disease and mortality, yet few health promotion initiatives are specifically aimed at men. Therefore, the aim of the ManUp Study is to examine the effectiveness of an IT-based intervention to increase the physical activity and nutrition behaviour and literacy in middle-aged males (aged 35–54 years. Method/Design The study design was a two-arm randomised controlled trial, having an IT-based (applying website and mobile phones and a print-based intervention arm, to deliver intervention materials and to promote self-monitoring of physical activity and nutrition behaviours. Participants (n = 317 were randomised on a 2:1 ratio in favour of the IT-based intervention arm. Both intervention arms completed assessments at baseline, 3, and 9 months. All participants completed self-report assessments of physical activity, sitting time, nutrition behaviours, physical activity and nutrition literacy, perceived health status and socio-demographic characteristics. A randomly selected sub-sample in the IT-based (n = 61 and print-based (n = 30 intervention arms completed objective measures of height, weight, waist circumference, and physical activity as measured by accelerometer (Actigraph GT3X. The average age of participants in the IT-based and print-based intervention arm was 44.2 and 43.8 years respectively. The majority of participants were employed in professional occupations (IT-based 57.6%, Print-based 54.2% and were overweight or obese (IT-based 90.8%, Print-based 87.3%. At baseline a lower proportion of participants in the IT-based (70.2% group agreed that 30 minutes of physical activity each day is enough to improve health compared to the print-based (82.3% group (p = .026. The IT-based group consumed a significantly lower number of serves of red meat in the previous week, compared to the print-based group (p = .017. No other significant

    Full Text Available Objective: To assess the national prevalence of clinical disorders in 6-year-old Iranian children before school entry using a national health assessment survey. Materials and Methods: In a cross-sectional nationwide survey, all Iranian children entering public and private elementary schools were asked to participate in a mandatory national screening program in Iran in 2009 in two levels of screening and diagnostic levels. Results: The study population consisted of 955388 children (48.5% girls and 76.1% urban. Of the whole children, 3.1% of the 6-year-old children had impaired vision. In addition, 1.2, 1.8, 1.4, 10, 10.9, 56.7, 0.7, 0.8 and 0.6% had color blindness, hearing impaired, speech disorder, height to age retardation, body mass index extremes, decayed teeth, having disease with special needs, spinal disorders, and hypertension, respectively. The distribution of these disorders was unequally distributed across provinces. Conclusions: Our results confirmed that the prevalence of clinical disorders among 6-year-old children across Iranian provinces was not similar. The observed burden of these distributions among young children needs a comprehensive national policy with evidence-based province programs to identify the reason for different distribution among provinces.

    An 11-week-old male entire French Bulldog was presented with a 3-week history of projectile vomiting after eating that was unresponsive to medical therapy. Ultrasonographic examination revealed a 1 x 2 cm pedunculated polypoid mass in the pyloric antrum. Histopathology showed this to be comprised of a pedunculated hyperplastic proliferation of gastric mucosal epithelium and submucosa, with dilatation of the glandular pits and a moderate degree of submucosal fibrosis and small amount of smooth muscle hyperplasia in the submucosa. The tunica muscularis was not involved in the polyp and appeared to be of normal thickness. Surgical treatment by pylorectomy and end-to-end gastroduodenostomy (Billroth I) was successful.

    To examine how visual impairment affects physical and cognitive function in old age. A longitudinal population-based prospective cohort study. General practitioner offices at six study centers in Germany. They were observed every 1.5 years over four waves. Individuals aged 77-101 at follow-up Wave 2 (N = 2,394). Physical and cognitive function were assessed using an adapted scale that had been previously developed, and visual impairment was rated on a Likert scale (none, mild, severe or profound). Adjusting for sociodemographic factors and comorbidity, linear fixed-effects regression showed that the onset of severe visual impairment was associated with a decline in physical function score in the total sample (β = -0.15, P = .01) and in women (β = -.15, P = .03). Moreover, the onset of severe visual impairment was associated with decline in cognitive function score in the total sample (β = -0.38, P Visual impairment affects physical and cognitive function in old age. Interventional strategies to postpone visual impairment may contribute to maintaining physical and cognitive function. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

  14. Finding meaning in a noisy world: exploring the effects of referential ambiguity and competition on 2·5-year-olds' cross-situational word learning.

    2016-04-07

    While recent studies suggest children can use cross-situational information to learn words, these studies involved minimal referential ambiguity, and the cross-situational evidence overwhelmingly favored a single referent for each word. Here we asked whether 2·5-year-olds could identify a noun's referent when the scene and cross-situational evidence were more ambiguous. Children saw four trials in which a novel word occurred with four novel objects; only one object consistently co-occurred with the word across trials. The frequency of distracter objects varied across conditions. When all distracter referents occurred only once (no-competition), children successfully identified the noun's referent. When a high-probability competitor referent occurred on three trials, children identified the target referent if the competitor was absent on the third trial (short-competition) but not if it was present until the fourth trial (long-competition). This suggests that although 2·5-year-olds' cross-situational learning scales up to more ambiguous scenes, it is disrupted by high-probability competitor referents.

    To estimate the prevalence of radiographic abnormalities (lesions) in Thoroughbred racehorses at 2-year-old in-training sales and determine whether these lesions and 1-furlong presale workout times were associated with subsequent racing performance. Retrospective cohort study. 953 Thoroughbreds. Repository radiographs of carpal, metacarpophalangeal and metatarsophalangeal (fetlock), stifle, and tarsal (hock) joints were examined. Horses with lesions were classified by lesion type and location. Race performance variables were compared between horses with and without lesions and between horses categorized by 1-furlong presale workout times (horses had ≥ 1 lesion, and 654 had no lesion detected. Odds of starting a race and of earning money racing were lower for horses with any lesion and lower for horses with proximal phalangeal dorsoproximal articular margin chip fracture, proximal sesamoid bone fracture or sesamoiditis, or wedge-shaped central or third tarsal bones, compared with horses that had no lesion. For horses that raced, proximal phalangeal dorsoproximal articular margin chip fractures were associated with lower lifetime earnings, and flattening of the medial femoral condyle was associated with fewer 3-year-old racing starts, compared with values for horses that had no lesion. Horses with workout times horses with slower workout times. No radiographic lesions prevented all affected horses from racing. Among horses that raced, few differences were found in performance for horses with and without lesions.

    To investigate the association between modifiable risk and protective factors and severe cognitive impairment and dementia in the very old. Additionally, the present study tests the predictive validity of the 'LIfestyle for BRAin health' (LIBRA) score, an index developed to assess an individual's dementia prevention potential. Two hundred seventy-eight individuals aged 85 years or older from the Cambridge City over-75s cohort study were followed-up until death. Included risk and protective factors were: diabetes, heart disease, hypertension, depression, smoking, low-to-moderate alcohol use, high cognitive activity, and physical inactivity. Incident severe cognitive impairment was based on the Mini-Mental State Examination (score: 0-17) and incident dementia was based on either post-mortem consensus clinical diagnostic assessments or death certificate data. Logistic regressions were used to test whether individual risk and protective factors and the LIBRA score were associated with severe cognitive impairment or dementia after 18 years follow-up. None of the risk and protective factors or the LIBRA score was significantly associated with increased risk of severe cognitive impairment or dementia. Sensitivity analyses using a larger sample, longer follow-up period, and stricter cut-offs for prevalent cognitive impairment showed similar results. Associations between well-known midlife risk and protective factors and risk for severe cognitive impairment or dementia might not persist into very old age, in line with suggestions that targeting these factors through lifestyle interventions should start earlier in life.

    Von Meyenburg complexes (VMCs), also known as bile duct hamartomas, are a part of a group of ductal plate malformations. They are typically present intrahepatically. In this case, we present to our knowledge the first report of an extra-hepatic VMC in the pediatric population. The patient presented as a 10-month-old infant with a weeklong history of progressive breathing difficulty. A chest radiograph was obtained, showing intestinal loops in the thoracic cavity consistent with a Morgagni's hernia, unrelated to his breathing difficulty. The patient then underwent an elective repair of his congenital diaphragmatic defect. During the operation, the bile duct hamartoma was found adherent to the accessory lobe of the liver, present to the left of the ligamentum teres.

  18. Management of craniosynostosis at an advanced age: Clinical findings and interdisciplinary treatment in a 17 year-old with pan-suture synostosis

    2015-03-01

    Full Text Available Craniosynostosis is the premature fusion of cranial sutures, occurring at a rate of approximately 1 in 2000 live births; it is usually diagnosed and treated within the first year-of-life. Some diagnoses are delayed and only detected later in childhood or adolescence when symptoms of increased intracranial pressure (ICP arise such as headaches and vision changes. We present a case of occult craniosynostosis in which a relatively normocephalic 17-year-old male presented with debilitating headaches, optic nerve edema, and developmental delay consistent with probable ICP elevation. CT scan demonstrated pan-suture craniosynostosis. Invasive monitoring confirmed increased ICP for which he underwent cranial remodeling and expansion. While the functional benefits of cranial remodeling are still vigorously debated, this patient’s headaches resolved postoperatively. Clinicians should be cognizant of cases of occult craniosynostosis, obtain the appropriate preoperative evaluations, and recognize the utility of cranial remodeling in appropriately selected patients.

    We report an unusual case of chronic mesenteric ischemia presenting in a 12-year-old girl with idiopathic infantile arterial calcinosis (IIAC). This is the first reported case in the literature of chronic mesenteric ischemia in the setting of IIAC. The girl presented with a classical history of postprandial abdominal pain. Imaging demonstrated significant stenoses of the celiac axis, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). Angioplasty of the celiac axis and SMA was attempted, with successful dilation of the SMA only. At 3-, 6- and 12-month follow-ups, the child's symptoms had almost resolved. This case report has three important ramifications: chronic mesenteric ischemia is a possible clinical presentation in children with IACC, pre-angioplasty imaging is important in guiding treatment approach, and angioplasty was effective in this case of chronic mesenteric ischemia and offers hope for other similarly affected children.

    We study the physics reach of an experiment where neutrinos produced in a beta-beam facility at CERN are observed in a large magnetized iron calorimeter (ICAL) at the India-based Neutrino Observatory (INO). The CERN-INO distance is close to the so-called "magic" baseline which helps evade some of the parameter degeneracies and allows for a better measurement of the neutrino mass hierarchy and $\\theta_{13}$.

    We introduce a new operator for general rationing problems in which, besides conflicting claims, individual baselines play an important role in the rationing process. The operator builds onto ideas of composition, which are not only frequent in rationing, but also in related problems...... such as bargaining, choice, and queuing. We characterize the operator and show how it preserves some standard axioms in the literature on rationing. We also relate it to recent contributions in such literature....

  2. The TDAQ Baseline Architecture

    CERN Multimedia

    Wickens, F J

    The Trigger-DAQ community is currently busy preparing material for the DAQ, HLT and DCS TDR. Over the last few weeks a very important step has been a series of meetings to complete agreement on the baseline architecture. An overview of the architecture indicating some of the main parameters is shown in figure 1. As reported at the ATLAS Plenary during the February ATLAS week, the main area where the baseline had not yet been agreed was around the Read-Out System (ROS) and details in the DataFlow. The agreed architecture has: Read-Out Links (ROLs) from the RODs using S-Link; Read-Out Buffers (ROB) sited near the RODs, mounted in a chassis - today assumed to be a PC, using PCI bus at least for configuration, control and monitoring. The baseline assumes data aggregation, in the ROB and/or at the output (which could either be over a bus or in the network). Optimization of the data aggregation will be made in the coming months, but the current model has each ROB card receiving input from 4 ROLs, and 3 such c...

    Congenital mixed hearing loss associated with fixed stapes footplate is a rare disorder transmitted through X-linked inheritance. The purpose of this study was to report the radiologic findings of X-linked deafness with middle ear anomalies in affected children and young patients and in carrier women. The computed tomographic and audiometric findings of 7 subjects (4 affected children and young patients, 1 of whom is a girl; 2 carrier mothers; and a man who presented with sudden hearing loss) from different families were analyzed. Computed tomography showed bulbous dilatation of the fundi of the internal auditory canals, incomplete bony separation between the basal turn of the cochleas and the lateral ends of the internal auditory canal, deficiency of the modiolus, enlarged first part of the facial nerve, and dilatation of the superior and the inferior vestibular nerve canal and the singular canal. Besides these characteristic findings, dilatation of the vestibular aqueduct was seen except in the man. Middle ear anomalies including oval and/or round window and/or stapes abnormalities were also detected in three affected patients. The carrier mothers had milder forms of some characteristic findings. Because of the risks of stapes surgery in X-linked deafness, recognition of the characteristic imaging features of these disorders is important. Especially in young patients with mixed hearing loss, temporal bone computed tomography should be performed before stapes surgery to avoid the complication of stapes gusher. Middle ear anomalies might be highly associated with X-linked deafness.

    Purpose Common age-related eye diseases including glaucoma, cataract and age-related macular degeneration (AMD) have been proposed to be associated with dementia. Several studies have examined the link between cognition and AMD but few have examined the relationship between cognition and cataract or glaucoma. We explored the association between cognition and cataract and glaucoma diagnoses in community-dwelling 85 year olds. Methods Cross-sectional analysis of data from the Newcastle 85+ Cohort study. Diagnoses of eye disease were extracted from family practice records. Cognitive performance was assessed by the standardised mini-mental state examination (sMMSE) and the MMSE-blind (MMblind). The relationships between glaucoma diagnosis or cataract diagnosis and lower cognition were examined using ordinal logistic regression. Results Complete data were available for 839 participants. Of these, 36.0% (302/839) had recorded previous cataract surgery, 11.2% (94/839) untreated cataract and 7.9% (66/839) diagnosed glaucoma. Glaucoma diagnosis was associated with lower sMMSE (odds ratio [95% confidence interval]:1.76[1.05-2.95]); but not with lower MMblind:1.17[0.65-2.12]. When compared to no cataract, cataract diagnosis (treated and untreated combined) was associated with higher sMMSE:0.55[0.38-0.79] and MMblind:0.51[0.34-0.76]. Previously treated cataract was associated with higher sMMSE:0.72[0.59-0.88] and MMblind:0.68[0.55-0.85]. Untreated cataract was not significantly associated with sMMSE:0.65[0.36-1.19] or MMblind:0.73[0.39-1.36]. Conclusions This large epidemiological study of 85 year olds found that lower sMMSE but not MMblind was associated with glaucoma diagnosis, suggesting the association may be driven by poor vision. Cataract diagnosis was associated with higher sMMSE and MMblind. Reasons for this observation are unclear but may relate to enhanced help seeking behaviour in people with diagnosed cataract.

    A cohort of 50-year-olds from Canterbury, New Zealand (N = 404), representative of midlife adults, undertook comprehensive health and dietary assessments. Fasting plasma vitamin C concentrations (N = 369) and dietary vitamin C intake (N = 250) were determined. The mean plasma vitamin C concentration was 44.2 µmol/L (95% CI 42.4, 46.0); 62% of the cohort had inadequate plasma vitamin C concentrations (i.e., C (i.e., C concentrations indicating deficiency (i.e., C concentration than women, and a higher percentage of vitamin C inadequacy and deficiency. A higher prevalence of hypovitaminosis C and deficiency was observed in those of lower socio-economic status and in current smokers. Adults with higher vitamin C levels exhibited lower weight, BMI and waist circumference, and better measures of metabolic health, including HbA1c, insulin and triglycerides, all risk factors for type 2 diabetes. Lower levels of mild cognitive impairment were observed in those with the highest plasma vitamin C concentrations. Plasma vitamin C showed a stronger correlation with markers of metabolic health and cognitive impairment than dietary vitamin C. PMID:28771190

    reservoirs along the Nueces River, the primary inflow for the system. The lack of long-term environmental monitoring records makes it difficult to disentangle the complex interrelationships between the natural and anthropogenic factors that have contributed to eutrophication. To address this issue, we are examining proxy evidence from sediment cores to look back in time, and understand the true baseline conditions and natural variability of these systems long before they were affected by anthropogenic impacts. We are using a suite of geological, chemical, and biological indicators including color spectral reflectance (for total chlorophyll content), organic carbon content via loss-on-ignition, Terrigenous/Aquatic Ratio (TARHC), TOC, C/N ratio analysis, pigment analysis via HPLC, and microfossil assemblage analysis. Age control for the stratigraphy will be provided by radiometric age analyses using 137Cs, 210Pb, and 14C. Initial results from spectral reflectance scanning of sediment cores from the Nueces Estuary appear to indicate an increased chlorophyll content up core, which probably reflects a long-term increase of primary productivity in the system.

    Full Text Available Abstract Background Many youth physical activity interventions have minimal effect. To design better interventions we need to understand more about the factors that influence youth activity. Application of self-determination theory to youth physical activity, particularly the relatedness and competence, might suggest that friends and friendship groups influence the initiation and maintenance of youth physical activity. In this study we examined this issue. Methods Seventeen focus groups were conducted with 113, 10–11 year old children, from 11 primary schools in Bristol, UK. Focus groups examined: 1 the nature of children's friendship groups; 2 associations between physical activity and social group status; and 3 how friendship groups affect the initiation and maintenance of physical activity. All focus groups were audio-taped and transcribed verbatim. Data were analyzed using content analysis. Results Participants reported that there were three different types of friendship groups; School friends; Neighborhood friends; and Other Friends who were friends from organized activities or children of their parents' friends. Participants had multiple groups of friends and engaged in different activities with the different groups. Possessing several groups of friends was desirable as it kept the friendships fresh and interesting. Physical activity was perceived as a positive attribute and linked to social status among boys. Among girls the association between physical activity ability and social status was more complex, appearing to differ by the norms of the group to which participants belonged. Some participants reported that low activity ability could be perceived as desirable in some social groups. Participants reported that friends provide support to initiate physical activity via co-participation (i.e. engaging in activity together; modeling of being active; and providing verbal support to engage in activity. Enjoyment was the most important

    Anal cytology has been suggested as a screening test for the anal cancer precursor high-grade squamous intraepithelial lesion (HSIL). We aimed to assess the prevalence and predictors of initial unsatisfactory anal cytology tests ('unsats'). The Study of the Prevention of Anal Cancer is a natural history study of anal human papillomavirus (HPV) and precancerous lesions among gay and bisexual men (GBM) of at least 35 years in Sydney, Australia. At each study visit, an anal swab is collected for cytological testing. Unsats are defined as slides with fewer than 2000 nucleated squamous cells and no abnormal cells. Among 617 GBM enrolled, the median age was 49 (range: 35-79) years and 220 (35.7%) were HIV positive. Initial unsats occurred in 61 (9.9%, 95% confidence interval: 7.6-12.5%), and 29 (4.7%, 95% confidence interval: 3.2-6.7%) remained unsatisfactory on repeat cytology. Initial unsats were associated with fewer lifetime anal-receptive partners with a condom (P=0.007); fewer recent anal-receptive sexual partners without a condom (P=0.005); never having had anal chlamydia (P=0.023) or gonorrhea (P=0.003); HIV-negative status (P=0.002); fewer total (P=0.002), low-risk (P=0.005), and high-risk (P=0.015) HPV types detected; lack of anal HPV18 detection (P=0.001); never having anally douched (Panal canal octants affected by HSIL (P=0.080), but were more common among those who felt more nervous (P=0.020) during the examination. Our findings suggest that unsats are more common among GBM with less receptive anal sexual experience. Avoiding douching with soapy water and strategies to aid patient relaxation during sampling may reduce the unsat rate.

    Full Text Available Abstract Background Systemic blood pressure, influenced by both genetic and environmental factors, is regulated via sympathetic nerve activity. We assessed the role of genetic variation in three subunits of the neuromuscular nicotinic acetylcholine receptor positioned on chromosome 2q, a region showing replicated evidence of linkage to blood pressure. Methods We sequenced CHRNA1, CHRND and CHRNG in 24 Amish subjects from the Amish Family Diabetes Study (AFDS and identified 20 variants. We then performed association analysis of non-redundant variants (n = 12 in the complete AFDS cohort of 1,189 individuals, and followed by genotyping blood pressure-associated variants (n = 5 in a replication sample of 1,759 individuals from the Framingham Heart Study (FHS. Results The minor allele of a synonymous coding SNP, rs2099489 in CHRNG, was associated with higher systolic blood pressure in both the Amish (p = 0.0009 and FHS populations (p = 0.009 (minor allele frequency = 0.20 in both populations. Conclusion CHRNG is currently thought to be expressed only during fetal development. These findings support the Barker hypothesis, that fetal genotype and intra-uterine environment influence susceptibility to chronic diseases later in life. Additional studies of this variant in other populations, as well as the effect of this variant on acetylcholine receptor expression and function, are needed to further elucidate its potential role in the regulation of blood pressure. This study suggests for the first time in humans, a possible role for genetic variation in the neuromuscular nicotinic acetylcholine receptor, particularly the gamma subunit, in systolic blood pressure regulation.

    Following the discovery of neutrino oscillations by the Super-Kamiokande collaboration, recently awarded with the Nobel Prize, two generations of long baseline experiments had been setup to further study neutrino oscillations. The first generation experiments, K2K in Japan, Minos in the States and Opera in Europe, focused in confirming the Super-Kamiokande result, improving the precision with which oscillation parameters had been measured and demonstrating the ντ appearance process. Second generation experiments, T2K in Japan and very recently NOνA in the States, went further, being optimized to look for genuine three neutrino phenomena like non-zero values of θ13 and first glimpses to leptonic CP violation (LCPV) and neutrino mass ordering (NMO). The discovery of leptonic CP violation will require third generation setups, at the moment two strong proposals are ongoing, Dune in the States and Hyper-Kamiokande in Japan. This review will focus a little more in these future initiatives.

    The European Union is promoting the use of biofuels and other renewable energy in transport. In April 2009, the Renewable Energy Directive (2009/28/EC) was adopted that set a 10% target for renewable energy in transport in 2020. The directive sets several requirements to the sustainability of biofuels marketed in the frame of the Directive. The Commission is required to report to the European Parliament on a regular basis on a range of sustainability impacts resulting from the use of biofuels in the EU. This report serves as a baseline of information for regular monitoring on the impacts of the Directive. Chapter 2 discusses the EU biofuels market, the production and consumption of biofuels and international trade. It is derived where the feedstock for EU consumed biofuels originally come from. Chapter 3 discusses the biofuel policy framework in the EU and major third countries of supply. It looks at various policy aspects that are relevant to comply with the EU sustainability requirements. Chapter 4 discusses the environmental and social sustainability aspects associated with EU biofuels and their feedstock. Chapter 5 discusses the macro-economic effects that indirectly result from increased EU biofuels consumption, on commodity prices and land use. Chapter 6 presents country factsheets for main third countries that supplied biofuels to the EU market in 2008.

    The authors describe the surgical approach, findings, and 8-year follow-up in a 29-year-old woman, with severe Freeman-Sheldon syndrome, presenting with congenital blepharophimosis of both upper eyelids resulting in near-complete functional visual obstruction. To avoid possible Freeman-Sheldon syndrome-associated complications of malignant hyperthermia, difficult vascular access, and challenging endotracheal intubation, the surgery was completed under local anesthesia without sedation, and anatomical and functional correction was immediate and remained stable at 8-year follow-up. Unlike many congenital craniofacial syndromes, which frequently involve life-long impairments, important implications exist for plastic surgeons to facilitate opportunities for patients to overcome functional limitations.

    Consistent cost and performance data for various electricity generation technologies can be difficult to find and may change frequently for certain technologies. With the Annual Technology Baseline (ATB), National Renewable Energy Laboratory provides an organized and centralized dataset that was reviewed by internal and external experts. It uses the best information from the Department of Energy laboratory's renewable energy analysts and Energy Information Administration information for conventional technologies. The ATB will be updated annually in order to provide an up-to-date repository of current and future cost and performance data. Going forward, we plan to revise and refine the values using best available information. The ATB includes both a presentation with notes (PDF) and an associated Excel Workbook. The ATB includes the following electricity generation technologies: land-based wind; offshore wind; utility-scale solar PV; concentrating solar power; geothermal power; hydropower plants (upgrades to existing facilities, powering non-powered dams, and new stream-reach development); conventional coal; coal with carbon capture and sequestration; integrated gasification combined cycle coal; natural gas combustion turbines; natural gas combined cycle; conventional biopower.

    A key milestone for the Immobilization Project (AOP Milestone 3.2a) in Fiscal Year 1998 (FY98) is the definition of the baseline composition or formulation for the plutonium ceramic form. The baseline formulation for the plutonium ceramic product must be finalized before the repository- and plant-related process specifications can be determined. The baseline formulation that is currently specified is given in Table 1.1. In addition to the baseline formulation specification, this report provides specifications for two alternative formulations, related compositional specifications (e.g., precursor compositions and mixing recipes), and other preliminary form and process specifications that are linked to the baseline formulation. The preliminary specifications, when finalized, are not expected to vary tremendously from the preliminary values given.

    The relationship between baseline (i.e., pre-injury) blood pressure and trauma outcomes in elderly patients is unknown. We therefore aimed to identify the independent impact of baseline systolic blood pressure (SBP) on inpatient mortality among elderly trauma patients. The 2004 to 2014 trauma registries of two Level I Trauma Centers were linked to electronic health records then reviewed to identify patients ≥65 years old with available baseline vital signs. Baseline SBP was defined as mean outpatient SBP within 2 years before injury. Trauma SBP was defined as first SBP reading after presentation for trauma. Baseline and Trauma SBP were classified as Low (Low, Normal, and High Baseline SBP groups, respectively (p = 0.001). In multivariable analyses, patients with Low Baseline SBP had significantly increased mortality risk [OR 3.19 (95% CI 1.62-6.26), p = 0.001] compared to patients with Normal Baseline SBP, in particular when they presented with Low Trauma SBP (Low Baseline SBP was particularly elevated among patients with a pre-existing diagnosis of hypertension [OR 4.78 (1.97-11.62), p = 0.001]. Low baseline pre-injury SBP is independently associated with more than a threefold increase in inpatient mortality among elderly trauma patients and a fivefold increase in mortality risk among patients with pre-existing hypertension. Given that blood pressure control in the elderly offers a long-term survival advantage, the paradoxical finding of decreased survival after trauma warrants further investigation.

    This baseline report supported an application by Connacher Oil and Gas Ltd. to the Alberta Energy and Utilities Board (EUB) and Alberta Environment (AENV) for the Great Divide Steam Assisted Gravity Drainage (SAGD) Project. The goal of the report was to document the distribution and occurrence of ecosite phases and wetland classes in the project footprint as well as to document the distribution of rare plants; rare plant communities: and intrusive species and old growth communities, including species of management concern. A methodology of the baseline report was presented, including details of mapping and field surveys. Six vegetation types in addition to the disturbed land unit were identified in the project footprint and associated buffer. It was noted that all vegetation types are common for the boreal forest natural regions. Several species of management concern were identified during the spring rare plant survey, including rare bryophytes and non-native or invasive species. Mitigation was identified through a slight shift of the footprint, transplant of appropriate bryophyte species and implementation of a weed management plan. It was noted that results of future surveys for rare plants will be submitted upon completion. It was concluded that the effects of the project on existing vegetation is expected to be low because of the small footprint, prior disturbance history, available mitigation measures and conservation and reclamation planning. 27 refs., 5 tabs., 4 figs.

    We review long-baseline neutrino experiments in which neutrinos are detected after traversing macroscopic distances. Over such distances neutrinos have been found to oscillate among flavor states. Experiments with solar, atmospheric, reactor, and accelerator neutrinos have resulted in a coherent picture of neutrino masses and mixing of the three known flavor states. We will summarize the current best knowledge of neutrino parameters and phenomenology with our focus on the evolution of the experimental technique. We proceed from the first evidence produced by astrophysical neutrino sources to the current open questions and the goals of future research.

    Studies were carried out on the FED Baseline to improve design definition, establish feasibility, and reduce cost. Emphasis was placed on cost reduction, but significant feasibility concerns existed in several areas, and better design definition was required to establish feasibility and provide a better basis for cost estimates. Design definition and feasibility studies included the development of a labyrinth shield ring concept to prevent radiation streaming between the torus spool and the TF coil cryostat. The labyrinth shield concept which was developed reduced radiation streaming sufficiently to permit contact maintenance of the inboard EF coils. Various concepts of preventing arcing between adjacent shield sectors were also explored. It was concluded that installation of copper straps with molybdenum thermal radiation shields would provide the most reliable means of preventing arcing. Other design studies included torus spool electrical/structural concepts, test module shielding, torus seismic response, poloidal conditions in the magnets, disruption characteristics, and eddy current effects. These additional studies had no significant impact on cost but did confirm the feasibility of the basic FED Baseline concept.

    The Pinellas Plant has been part of the Department of Energy`s (DOE) nuclear weapons complex since the plant opened in 1957. In March 1995, the DOE sold the Pinellas Plant to the Pinellas County Industry Council (PCIC). DOE has leased back a large portion of the plant site to facilitate transition to alternate use and safe shutdown. The current mission is to achieve a safe transition of the facility from defense production and prepare the site for alternative uses as a community resource for economic development. Toward that effort, the Pinellas Plant Environmental Baseline Report (EBR) discusses the current and past environmental conditions of the plant site. Information for the EBR is obtained from plant records. Historical process and chemical usage information for each area is reviewed during area characterizations.

    The U.S. Department of Energy (DOE) is planning a two-phased program for the remediation of Hanford tank waste. Phase 1 is a pilot program to demonstrate the procurement of treatment services. The volume of waste treated during the Phase 1 is a small percentage of the tank waste. During Phase 2, DOE intends to procure treatment services for the balance of the waste. The TWRS Privatization Process Technical Baseline (PPTB) provides a summary level flowsheet/mass balance of tank waste treatment operations which is consistent with the tank inventory information, waste feed staging studies, and privatization guidelines currently available. The PPTB will be revised periodically as privatized processing concepts are crystallized.

    Depressive disorders are common among the very old, but insufficiently studied. The present study aims to identify risk factors for depressive disorders in very old age. The present study is based on the GERDA project, a population-based cohort study of people aged ≥85 years (n = 567), with 5 years between baseline and follow-up. Factors associated with the development of depressive disorders according to DSM-IV criteria at follow-up were analysed by means of a multivariate logistic regression. At baseline, depressive disorders were present in 32.3 % of the participants. At follow-up, 69 % of those with baseline depressive disorders had died. Of the 49 survivors, 38 still had depressive disorders. Of the participants without depressive disorders at baseline, 25.5 % had developed depressive disorders at follow-up. Baseline factors independently associated with new cases of depressive disorders after 5 years were hypertension, a history of stroke and 15-item Geriatric Depression Scale score at baseline. The present study supports the earlier findings that depressive disorders among the very old are common, chronic and malignant. Mild depressive symptoms as indicated by GDS-15 score and history of stroke or hypertension seem to be important risk factors for incident depressive disorders in very old age.

    The purpose of this study was to investigate the level of life satisfaction and the significant factors which impact on life satisfaction of young-old (60-69 yr), old (70-79 yr), and oldest-old (80 yr or above) women. The participants for this study were 289 elderly Korean women living in the city of Daegu and Kyongpook province. The data were collected using structured questionnaires. ANOVA, Chi-square, and multiple regression with the SPSS program were used to analyze the data. There were statistically significant differences among young-old, old, and oldest-old women regarding the existence of spouse, income, educational status, and religions. The model including variables related to physical, psychological, financial, and social aspects of life, explained variance of life satisfaction of elderly women differently, such as 55% of young-old, 37% of old, and 66% of oldest-old. Finally, self-esteem was the only predictor in explaining the level of life satisfaction among old women regardless age. Based on the findings of the study, implications for practical services for elderly women and recommendations of further study are provided. Nursing interventions should be developed to improve life satisfaction of elderly women according to age differences.

    Cushing’s syndrome (CS) is uncommon in childhood. CS may be either dependent or independent of adrenocorticotrophic hormone (ACTH). ACTH independent micronodular adrenocortical (MAD) disease may present in the second to third decade of life or between ages 2–3years. It may occur in isolation, or as a part of the Carney complex and it represents an elusive entity to diagnose. We present a 3 year 7 month old boy with isolated MAD (iMAD). Abdominal CT revealed prominent mildly lobulated anteromedial margin of adrenals with nodular appearance. Cardiac echo, thyroid and testicular ultrasounds performed as a work up for Carney complex were normal. Bilateral adrenalectomy confirmed MAD as the cause of CS. We present the history’ and identification of a unique case of iMAD. PMID:20662336

    We outline the LOFAR Long-Baseline Calibrator Survey (LBCS), whose aim is to identify sources suitable for calibrating the highest-resolution observations made with the International LOFAR Telescope, which include baselines >1000 km. Suitable sources must contain significant correlated flux density (≳ 50 - 100 mJy) at frequencies around 110-190 MHz on scales of a few hundred milliarcseconds. At least for the 200-300-km international baselines, we find around 1 suitable calibrator source per square degree over a large part of the northern sky, in agreement with previous work. This should allow a randomly selected target to be successfully phase calibrated on the international baselines in over 50% of cases. Products of the survey include calibrator source lists and fringe-rate and delay maps of wide areas - typically a few degrees - around each source. The density of sources with significant correlated flux declines noticeably with baseline length over the range 200-600 km, with good calibrators on the longest baselines appearing only at the rate of 0.5 per sq. deg. Coherence times decrease from 1-3 min on 200-km baselines to about 1 min on 600-km baselines, suggesting that ionospheric phase variations contain components with scales of a few hundred kilometres. The longest median coherence time, at just over 3 min, is seen on the DE609 baseline, which at 227 km is close to being the shortest. We see median coherence times of between 80 and 110 s on the four longest baselines (580-600 km), and about 2 min for the other baselines. The success of phase transfer from calibrator to target is shown to be influenced by distance, in a manner that suggests a coherence patch at 150-MHz of the order of 1 deg. Although source structures cannot be measured in these observations, we deduce that phase transfer is affected if the calibrator source structure is not known. We give suggestions for calibration strategies and choice of calibrator sources, and describe the access to

    Overexploitation leads to the ecological extinction of many oceanic species. The depletion of historical abundances of large animals, such as whales and sea turtles, is well known. However, the magnitude of the historical overfishing of exploited invertebrates is unclear. The lack of rigorous baseline data limits the implementation of efficient management and conservation plans in the marine realm. The precious Mediterranean red coral Corallium rubrum has been intensively exploited since antiquity for its use in jewellery. It shows dramatic signs of overexploitation, with no untouched populations known in shallow waters. Here, we report the discovery of an exceptional red coral population from a previously unexplored shallow underwater cave in Corsica (France) harbouring the largest biomass (by more than 100-fold) reported to date in the Mediterranean. Our findings challenge current assumptions on the pristine state of this emblematic species. Our results suggest that, before intense exploitation, red coral lived in relatively high-density populations with a large proportion of centuries-old colonies, even at very shallow depths. We call for the re-evaluation of the baseline for red coral and question the sustainability of the exploitation of a species that is still common but ecologically (functionally) extinct and in a trajectory of further decline.

    2010-09-15

    In Finland, a Government Decree on the Assessment of Soil Contamination and Remediation Needs has generated a need for reliable and readily accessible data on geochemical baseline concentrations in Finnish soils. According to the Decree, baseline concentrations, referring both to the natural geological background concentrations and the diffuse anthropogenic input of substances, shall be taken into account in the soil contamination assessment process. This baseline information is provided in a national geochemical baseline database, TAPIR, that is publicly available via the Internet. Geochemical provinces with elevated baseline concentrations were delineated to provide regional geochemical baseline values. The nationwide geochemical datasets were used to divide Finland into geochemical provinces. Several metals (Co, Cr, Cu, Ni, V, and Zn) showed anomalous concentrations in seven regions that were defined as metal provinces. Arsenic did not follow a similar distribution to any other elements, and four arsenic provinces were separately determined. Nationwide geochemical datasets were not available for some other important elements such as Cd and Pb. Although these elements are included in the TAPIR system, their distribution does not necessarily follow the ones pre-defined for metal and arsenic provinces. Regional geochemical baseline values, presented as upper limit of geochemical variation within the region, can be used as trigger values to assess potential soil contamination. Baseline values have also been used to determine upper and lower guideline values that must be taken into account as a tool in basic risk assessment. If regional geochemical baseline values are available, the national guideline values prescribed in the Decree based on ecological risks can be modified accordingly. The national geochemical baseline database provides scientifically sound, easily accessible and generally accepted information on the baseline values, and it can be used in various

  1. Detection of abrupt baseline length changes using cumulative sums

    Science.gov (United States)

    Janssen, Volker

    2009-06-01

    Dynamic processes are usually monitored by collecting a time series of observations, which is then analysed in order to detect any motion or non-standard behaviour. Geodetic examples include the monitoring of dams, bridges, high-rise buildings, landslides, volcanoes and tectonic motion. The cumulative sum (CUSUM) test is recognised as a popular means to detect changes in the mean and/or the standard deviation of a time series and has been applied to various monitoring tasks. This paper briefly describes the CUSUM technique and how it can be utilised for the detection of small baseline length changes by differencing two perpendicular baselines sharing a common site. A simulation is carried out in order to investigate the expected behaviour of the resulting CUSUM charts for a variety of typical deformation monitoring scenarios. This simulation shows that using first differences (between successive epochs) as input, rather than the original baseline lengths, produces clear peaks or jumps in the differenced CUSUM time series when a sudden change in baseline length occurs. These findings are validated by analysing several GPS baseline pairs of a network deployed to monitor the propagation of an active ice shelf rift on the Amery Ice Shelf, East Antarctica.

    This study investigated the baseline predictors of best corrected visual acuity (BCVA) and central retinal thickness (CRT) at 6 months in patients with treatment-naïve branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). This multicenter, interventional case series included 208 BRVO and 123 CRVO patients with follow-up period of 6 months or more. Outcome measures of BCVA (logMAR) included absolute change from baseline and a gain or loss of ≥ 0.3 from baseline. Outcome measures of CRT included absolute change from baseline and a measurement of ≤ 250 µm or ≥ 400 µm at 6 months. Univariate and multiple regression analyses were done to find baseline predictors. For BRVO, younger age, worse baseline BCVA, and shorter duration of symptom were associated with more gain in BCVA. For CRVO, worse baseline BCVA was associated with more gain in BCVA. For CRT outcomes, higher baseline CRT predicted greater decrease at 6 months in both BRVO and CRVO. Younger age and better baseline BCVA were associated with an increased likelihood of measurement of a ≤ 250 µm outcome for BRVO and CRVO, respectively. For CRVO, smoking was associated with greater decrease from baseline and decreased likelihood of measurement of a CRT ≥ 400 µm at 6 months. In conclusion, several baseline factors including age, symptom duration, and baseline BCVA and CRT are associated with BCVA and CRT outcomes at 6 months, which may help to predict disease course for RVO patients.

    The Baseline Values and Assumptions Document (BVAD) provides analysts, modelers, and other life support researchers with a common set of values and assumptions which can be used as a baseline in their studies. This baseline, in turn, provides a common point of origin from which many studies in the community may depart, making research results easier to compare and providing researchers with reasonable values to assume for areas outside their experience. With the ability to accurately compare different technologies' performance for the same function, managers will be able to make better decisions regarding technology development.

    Late life involves a variety of different challenges to well-being. This study extends and qualifies propositions drawn from the paradox of well-being in aging using 15-year longitudinal data on depressive symptoms from old and very old participants in the Australian Longitudinal Study of Ageing (Baseline N = 2,087; Mage = 78.69 years; range: 65-103 years; 49.40% women). We first examined age-related trajectories in depressive symptoms from young-old to oldest-old, taking into account (changes in) relevant correlates, pathology, and mortality; and, second, we investigated gender differences in these trajectories. Results revealed that age-related trajectories of depressive symptoms were predictive of mortality hazards. The unique predictive effects of both level of, and change in, depressive symptoms were independent of one another and held after taking into account education as well as changes in marital status, living arrangements, cognitive function, and illness burden. In addition, results indicated that depressive symptoms were elevated among participants suffering from arthritis, and increased with age more markedly in men than in women. In particular, the significant Age × Gender interaction indicated that the gender gap in depressive symptoms reduced from young-old to old-old and reversed in very old age when men showed more depressive symptoms than women. Qualifying the paradox of well-being in aging, findings demonstrated that depressive symptoms increased from young-old to oldest-old and suggest that age-, pathology-, and mortality-related changes should be examined in concert to advance our understanding of individual differences in depressive symptom trajectories in late life.

    Groundwater is a vital source of freshwater in the UK. It provides almost 30% of public water supply on average, but locally, for example in south-east England, it is constitutes nearly 90% of public supply. In addition to public supply, groundwater has a number of other uses including agriculture, industry, and food and drink production. It is also vital for maintaining river flows especially during dry periods and so is essential for maintaining ecosystem health. Recently, there have been concerns expressed about the potential impacts of shale gas development on groundwater. The UK has abundant shales and clays which are currently the focus of considerable interest and there is active research into their characterisation, resource evaluation and exploitation risks. The British Geological Survey (BGS) is undertaking research to provide information to address some of the environmental concerns related to the potential impacts of shale gas development on groundwater resources and quality. The aim of much of this initial work is to establish environmental baselines, such as a baseline survey of methane occurrence in groundwater (National methane baseline study) and the spatial relationships between potential sources and groundwater receptors (iHydrogeology project), prior to any shale gas exploration and development. The poster describes these two baseline studies and presents preliminary findings. BGS are currently undertaking a national survey of baseline methane concentrations in groundwater across the UK. This work will enable any potential future changes in methane in groundwater associated with shale gas development to be assessed. Measurements of methane in potable water from the Cretaceous, Jurassic and Triassic carbonate and sandstone aquifers are variable and reveal methane concentrations of up to 500 micrograms per litre, but the mean value is relatively low at 2km. The geological modelling process will be presented and discussed along with maps combining

    angle θ of its corresponding rays w.r.t. the optical axis as θ = ar 1+br2 . After a successful calibration, we know the correspondence of the image points to the 3D optical rays in the coordinate system of the camera. The following steps aim at finding the transformation between the camera and the world coordinate systems, i.e. the pose of the camera in the 3D world, using 2D image matches. For computing 3D structure, we construct a set of tentative matches detecting different affine covariant feature regions including MSER, Harris Affine, and Hessian Affine in acquired images. These features are alternative to popular SIFT features and work comparably in our situation. Parameters of the detectors are chosen to limit the number of regions to 1-2 thousands per image. The detected regions are assigned local affine frames (LAF) and transformed into standard positions w.r.t. their LAFs. Discrete Cosine Descriptors are computed for each region in the standard position. Finally, mutual distances of all regions in one image and all regions in the other image are computed as the Euclidean distances of their descriptors and tentative matches are constructed by selecting the mutually closest pairs. Opposed to the methods using short baseline images, simpler image features which are not affine covariant cannot be used because the view point can change a lot between consecutive frames. Furthermore, feature matching has to be performed on the whole frame because no assumptions on the proximity of the consecutive projections can be made for wide baseline images. This is making the feature detection, description, and matching much more time-consuming than it is for short baseline images and limits the usage to low frame rate sequences when operating in real-time. Robust 3D structure can be computed by RANSAC which searches for the largest subset of the set of tentative matches which is, within a predefined threshold ", consistent with an epipolar geometry. We use ordered sampling as

    Full Text Available Acquisition of mutans streptococci has been reported to most commonly occur at approximately 26 months of age. In the present study, we detected Streptococcus mutans and S. sobrinus using polymerase chain reaction (PCR assays in children, then re-examined the subjects to determine the time of acquisition of these bacteria over a 1-year period. The subjects were 57 children ranging in age from 3 to 5 years old, each with primary dentition. Plaque samples were collected from all erupted tooth sites using a sterile toothbrush. PCR assays were performed to detect the targeted mutans streptococci at the beginning of the study (baseline and after 1 year. At the baseline examination, the prevalence of S. mutans and S. sobrinus was 61.4% and 54.4%, respectively, in all subjects, of whom 14 (24.6% were positive for S. mutans alone, 10 (17.5% for S. sobrinus alone, and 21 (36.8% for both S. mutans and S. sobrinus, with 12 (21.1% negative for both. After 1 year, 4 of 22 (18.2% subjects newly had acquired S. mutans and 15 of 26 (57.7% had aquired S. sobrinus, while 5 (8.8% remained negative for both bacteria. The age of the first positive S. mutans finding ranged from 49 to 71 months, while that for S. sobrinus ranged from 49 to 81 months old. Our results suggest that S. sobrinus becomes established later than S. mutans in the oral cavities of children over the age of 3 years old.

    @@ To cast this sage historical advice into contemporary terms,the eternal human predisposition to believe in flimsy promises of rejuvenation needs to be well understood,or repeated.As an ingenious species,we have made grand advances in overcoming the physical limits of our biology.Yet while technology has overcome our native ponderous,gravity-and land-bound locomotion with air,land and sea travel,the irreversibility of time and inevitability of death remain stubbornly unyielding.Even such prolongation of lifespan that we have achieved only reveals more starkly the progressive somatic decay and waning of virility which erode dreams of enduring youthful vigour.Lurking just below the conscious horizon,wishful thinking about rejuvenation regularly resurfaces whenever social conditions favour such indulgence.

    Baseline data are provided on three species of fish from the Salton Sea, California. The fishes considered were the orange mouth corvina (Cynoscion xanthulus), gulf croaker (Bairdiella icistius) and sargo (Anisotremus davidsonii). Morphometric and meristic data are presented as a baseline to aid in the evaluation of any physiological stress the fish may experience as a result of geothermal development. Analyses were made on muscle, liver, and bone of the fishes sampled to provide baseline data on elemental tissue burdens. The elements measured were: As, Br, Ca, Cu, Fe, Ga, K, Mn, Mi, Pb, Rb, Se, Sr, Zn, and Zr. These data are important if an environmentally sound progression of geothermal power production is to occur at the Salton Sea.

    Full Text Available OBJECTIVE: Determine the prevalence of medication use in children and adolescents in 20 municipalities of Vale do Jequitinhonha, Minas Gerais-Brazil, showing the main groups and variables that may have influenced use. METHODS: Descriptive population-based survey sample of 555 interviews, selected by simple random cluster sampling of 137 census tracts. Inclusion criteria were age ≤ 14 years, mandatory interview with the legal guardians, and regardless of having received medications. Regarding the usage pattern, participants were divided into two groups: consumption and non-consumption of drugs. A descriptive analysis of the variables and tests of association were performed. RESULTS: The prevalence of drug consumption was 56.57%, and 42.43% showed no consumption. The use of medicinal plants was 72.9% for drug users and 74.3% for non-users. The health conditions for consumption were cough, common cold, flu, nasal congestion or bronchospasm (49.7%, fever (5.4%, headache (5.4%, diarrhea, indigestion, and abdominal colic (6.7%. In cases of self-medication, 30.57% of the drugs were given by the mother, and 69.42% were prescription drugs. Self-medication was prevalent using paracetamol (30.2%, dipyrone (20.8%, and cold medicine (18.8%. There was increased use of analgesics/antipyretics, followed by respiratory medications, systemic antibiotics, histamine H1 antagonists, and vitamins/antianemics. CONCLUSIONS: The prevalence of drugs use in children was high, indicating the need for formulating educational programs aiming at the awareness of caregivers regarding rational use.

    The objective of this study was to examine the associations between baseline electroencephalogram (EEG)-assessed brain oscillations and subsequent response to four neuromodulatory treatments. Based on available research, we hypothesized that baseline theta oscillations would prospectively predict response to hypnotic analgesia. Analyses involving other oscillations and the other treatments (meditation, neurofeedback, and both active and sham transcranial direct current stimulation) were viewed as exploratory, given the lack of previous research examining brain oscillations as predictors of response to these other treatments. Randomized controlled study of single sessions of four neuromodulatory pain treatments and a control procedure. Thirty individuals with spinal cord injury and chronic pain had their EEG recorded before each session of four active treatments (hypnosis, meditation, EEG biofeedback, transcranial direct current stimulation) and a control procedure (sham transcranial direct stimulation). As hypothesized, more presession theta power was associated with greater response to hypnotic analgesia. In exploratory analyses, we found that less baseline alpha power predicted pain reduction with meditation. The findings support the idea that different patients respond to different pain treatments and that between-person treatment response differences are related to brain states as measured by EEG. The results have implications for the possibility of enhancing pain treatment response by either 1) better patient/treatment matching or 2) influencing brain activity before treatment is initiated in order to prepare patients to respond. Research is needed to replicate and confirm the findings in additional samples of individuals with chronic pain. Wiley Periodicals, Inc.

    The Kyoto Protocol and the Clean Development Mechanism (CDM) came into force on 16th February 2005 with its ratification by Russia. The increasing momentum of this process is reflected in more than 100 projects having been submitted to the CDM Executive Board (CDM-EB) for approval of the baselines and monitoring methodologies, which is the first step in developing and implementing CDM projects. A CDM project should result in a net decrease of GHG emissions below any level that would have resulted from other activities implemented in the absence of that CDM project. The 'baseline' defines the GHG emissions of activities that would have been implemented in the absence of a CDM project. The baseline methodology is the process/algorithm for establishing that baseline. The baseline, along with the baseline methodology, are thus the most critical element of any CDM project towards meeting the important criteria of CDM, which are that a CDM should result in 'real, measurable, and long term benefits related to the mitigation of climate change'. This guidebook is produced within the frame work of the United Nations Environment Programme (UNEP) facilitated 'Capacity Development for the Clean Development Mechanism (CD4CDM)' Project. This document is published as part of the projects effort to develop guidebooks that cover important issues such as project finance, sustainability impacts, legal framework and institutional framework. These materials are aimed to help stakeholders better understand the CDM and are believed to eventually contribute to maximize the effect of the CDM in achieving the ultimate goal of UNFCCC and its Kyoto Protocol. This Guidebook should be read in conjunction with the information provided in the two other guidebooks entitled, 'Clean Development Mechanism: Introduction to the CDM' and 'CDM Information and Guidebook' developed under the CD4CDM project.

    2017-04-01

    The soil element concentrations regionally vary a lot in Finland. Mostly this is caused by the different bedrock types, which are reflected in the soil qualities. Geological Survey of Finland (GTK) is carrying out geochemical baseline studies in Finland. In the previous phase, the research is focusing on urban areas and mine environments. The information can, for example, be used to determine the need for soil remediation, to assess environmental impacts or to measure the natural state of soil in industrial areas or mine districts. The field work is done by taking soil samples, typically at depth between 0-10 cm. Sampling sites are chosen to represent the most vulnerable areas when thinking of human impacts by possible toxic soil element contents: playgrounds, day-care centers, schools, parks and residential areas. In the mine districts the samples are taken from the areas locating outside the airborne dust effected areas. Element contents of the soil samples are then analyzed with ICP-AES and ICP-MS, Hg with CV-AAS. The results of the geochemical baseline studies are published in the Finnish national geochemical baseline database (TAPIR). The geochemical baseline map service is free for all users via internet browser. Through this map service it is possible to calculate regional soil baseline values using geochemical data stored in the map service database. Baseline data for 17 elements in total is provided in the map service and it can be viewed on the GTK's web pages (http://gtkdata.gtk.fi/Tapir/indexEN.html).

  5. Neutrino Interactions and Long-Baseline Experiments

    CERN Document Server

    Mosel, Ulrich

    2016-01-01

    The extraction of neutrino mixing parameters and the CP-violating phase requires knowledge of the neutrino energy. This energy must be reconstructed from the final state of a neutrino-nucleus reaction since all long-baseline experiments use nuclear targets. This reconstruction requires detailed knowledge of the neutrino reactions with bound nucleons and of the final state interactions of hadrons with the nuclear environment. Quantum-kinetic transport theory can be used to build an event generator for this reconstruction that takes basic nuclear properties, such as binding, into account. Some examples are discussed that show the effects of nuclear interactions on observables in long-baseline experiments

    2017-01-01

    The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino oscillation experiment with primary physics goals of determining the neutrino mass hierarchy and measuring δc P with sufficient sensitivity to discover CP violation in neutrino oscillation. CP violation sensitivity in DUNE requires careful understanding of systematic uncertainty, with contributions expected from uncertainties in the neutrino flux, neutrino interactions, and detector effects. In this presentation, we will describe the expected sensitivity of DUNE to long-baseline neutrino oscillation parameters, how various aspects of the experimental design contribute to that sensitivity, and the planned strategy for constraining systematic uncertainty in these measurements.

    We perform a comprehensive study of the ability of the Long-Baseline Neutrino Experiment (LBNE) to answer outstanding questions in the neutrino sector. We consider the sensitivities to the mass hierarchy, the octant of $\\theta_{23}$ and to CP violation using data from beam and atmospheric neutrinos. We evaluate the dependencies on the precision with which $\\theta_{13}$ will be measured by reactor experiments, on the detector size, beam power and exposure time, on detector magnetization, and on the systematic uncertainties achievable with and without a near detector. We find that a 35 kt LBNE with a near detector will resolve the eight-fold degeneracy that is intrinsic to long baseline experiments and will meet the primary goals of oscillation physics that it is designed for.

    2014-01-01

    Full Text Available The discovery of neutrino mixing and oscillations over the past decade provides firm evidence for new physics beyond the Standard Model. Recently, θ13 has been determined to be moderately large, quite close to its previous upper bound. This represents a significant milestone in establishing the three-flavor oscillation picture of neutrinos. It has opened up exciting prospects for current and future long-baseline neutrino oscillation experiments towards addressing the remaining fundamental questions, in particular the type of the neutrino mass hierarchy and the possible presence of a CP-violating phase. Another recent and crucial development is the indication of non-maximal 2-3 mixing angle, causing the octant ambiguity of θ23. In this paper, I will review the phenomenology of long-baseline neutrino oscillations with a special emphasis on sub-leading three-flavor effects, which will play a crucial role in resolving these unknowns. First, I will give a brief description of neutrino oscillation phenomenon. Then, I will discuss our present global understanding of the neutrino mass-mixing parameters and will identify the major unknowns in this sector. After that, I will present the physics reach of current generation long-baseline experiments. Finally, I will conclude with a discussion on the physics capabilities of accelerator-driven possible future long-baseline precision oscillation facilities.

    2017-03-01

    We present millimeter- and submillimeter-wave phase characteristics measured between 2012 and 2014 of Atacama Large Millimeter/submillimeter Array long baseline campaigns. This paper presents the first detailed investigation of the characteristics of phase fluctuation and phase correction methods obtained with baseline lengths up to ∼15 km. The basic phase fluctuation characteristics can be expressed with the spatial structure function (SSF). Most of the SSFs show that the phase fluctuation increases as a function of baseline length, with a power-law slope of ∼0.6. In many cases, we find that the slope becomes shallower (average of ∼0.2–0.3) at baseline lengths longer than ∼1 km, namely showing a turn-over in SSF. These power law slopes do not change with the amount of precipitable water vapor (PWV), but the fitted constants have a weak correlation with PWV, so that the phase fluctuation at a baseline length of 10 km also increases as a function of PWV. The phase correction method using water vapor radiometers (WVRs) works well, especially for the cases where PWV > 1 {mm}, which reduces the degree of phase fluctuations by a factor of two in many cases. However, phase fluctuations still remain after the WVR phase correction, suggesting the existence of other turbulent constituent that cause the phase fluctuation. This is supported by occasional SSFs that do not exhibit any turn-over; these are only seen when the PWV is low (i.e., when the WVR phase correction works less effectively) or after WVR phase correction. This means that the phase fluctuation caused by this turbulent constituent is inherently smaller than that caused by water vapor. Since in these rare cases there is no turn-over in the SSF up to the maximum baseline length of ∼15 km, this turbulent constituent must have scale height of 10 km or more, and thus cannot be water vapor, whose scale height is around 1 km. Based on the characteristics, this large scale height turbulent constituent is

    1990-01-01

    CASA Uno data from sites distributed in longitude from Australia to Europe have been used to determine orbits of the GPS satellites. The characteristics of the orbits determined from double difference phase have been evaluated through comparisons of two-week solutions with one-week solutions and by comparisons of predicted and estimated orbits. Evidence of unmodeled effects is demonstrated, particularly associated with the orbit planes that experience solar eclipse. The orbit accuracy has been assessed through the repeatability of unconstrained estimated baseline vectors ranging from 245 km to 5400 km. Both the baseline repeatability and the comparison with independent space geodetic methods give results at the level of 1-2 parts in 100,000,000. In addition, the Mojave/Owens Valley (245 km) and Kokee Park/Ft. Davis (5409 km) estimates agree with VLBI and SLR to better than 1 part in 100,000,000.

    Full Text Available We propose a technique to provide interferometry by combining multiple images of the same area. This technique differs from the multi-baseline approach in literature as (a it exploits all the images simultaneously, (b it performs a spectral shift preprocessing to remove most of the decorrelation, and (c it exploits distributed targets. The technique is mainly intended for DEM generation at centimetric accuracy, as well as for differential interferometry. The problem is framed in the contest of single-input multiple-output (SIMO channel estimation via the cross-relations (CR technique and the resulting algorithm provides significant improvements with respect to conventional approaches based either on independent analysis of single interferograms or multi-baselines phase analysis of single pixels of current literature, for those targets that are correlated in all the images, like for long-term coherent areas, or for acquisitions taken with a short revisit time (as those gathered with future satellite constellations.

    2016-01-01

    The propagation of neutrinos in long baselines experiments may be influenced by dissipation effects. Using Lindblad Master Equation we evolve neutrinos taking into account these dissipative effects. The MSW and the dissipative effects may change the probabilities behavior. In this work, we show and explain how the behavior of the probabilities can change due to the decoherence and relaxation effects acting individually with the MSW effect. A new exotic peak appears in this case and we show the difference between the decoherence and relaxation effects in the appearance of this peak. We also adapt the usual approximate expression for survival and appearance probabilities with all possible decoherence effects. We suppose the baseline of DUNE and show how each decoherence parameters change the probabilities analyzing the possible modification using numeric and analytic approach.

    2006-02-01

    This article gives a brief overview of long baseline neutrino experiments and their goals, and then describes the different kinds of systematic errors that are encountered in these experiments. Particular attention is paid to the uncertainties that come about because of imperfect knowledge of neutrino cross sections and more generally how neutrinos interact in nuclei. Near detectors are planned for most of these experiments, and the extent to which certain uncertainties can be reduced by the presence of near detectors is also discussed.

    In this report, we present computed tomographic findings of colonic trichuriasis. The patient was a 75-year-old man who complained of abdominal pain, and weight loss.Diagnosis was achieved by colonoscopic biopsy. Abdominal computed tomography showed irregular and nodular thickening of the wall of the cecum and ascending colon.Although these findings are nonspecific, they may be one of the findings of trichuriasis. These findings, confirmed by pathologic analysis of the biopsied tissue and KatoKatz parasitological stool flotation technique, revealed adult Trichuris. To our knowledge, this is the first report of colonic trichuriasis indicated by computed tomography.

    1975-04-01

    This report comprises one part of a final report to the Alumax Pacific Aluminum Corporation on the Physical, Chemical and Biological Studies of Youngs Bay''. The data reported herein are the product of the geochemical baseline section of the project. The primary objectives of the geochemical study were: to provide a baseline record of fluoride and selected trace metal levels in Youngs Bay bottom sediment, to identify areas that might function as heavy metal traps, to attempt to determine the recent depositional history of sediment in the bay. In addition to these primary objectives, a number of secondary tasks were undertaken during the study. While time did not allow these additional studies to be carried to completion, preliminary results are included herein because of their potential usefulness in assessing the impact of environmental releases of fluoride to aquatic systems in the vicinity of Youngs Bay or elsewhere. This report is made up of two major sections. In the first, a description of sample collection and analytical procedures is followed by a discussion of the baseline results. Obvious vertical and horizontal patterns of elemental distribution are identified and their origins considered. Problems needed further research are also discussed. In the second section, the data are presented in interpretive, graphical form, as well as in tables. 35 refs., 29 figs., 14 tabs.

  4. Efficient Wide Baseline Structure from Motion

    Science.gov (United States)

    Michelini, Mario; Mayer, Helmut

    2016-06-01

    This paper presents a Structure from Motion approach for complex unorganized image sets. To achieve high accuracy and robustness, image triplets are employed and (an approximate) camera calibration is assumed to be known. The focus lies on a complete linking of images even in case of large image distortions, e.g., caused by wide baselines, as well as weak baselines. A method for embedding image descriptors into Hamming space is proposed for fast image similarity ranking. The later is employed to limit the number of pairs to be matched by a wide baseline method. An iterative graph-based approach is proposed formulating image linking as the search for a terminal Steiner minimum tree in a line graph. Finally, additional links are determined and employed to improve the accuracy of the pose estimation. By this means, loops in long image sequences are implicitly closed. The potential of the proposed approach is demonstrated by results for several complex image sets also in comparison with VisualSFM.

    The knowledge generated from evidence-based interventions in mental health systems research is seldom translated into policy and practice in low and middle-income countries (LMIC). Stakeholder analysis is a potentially useful tool in health policy and systems research to improve understanding of policy stakeholders and increase the likelihood of knowledge translation into policy and practice. The aim of this study was to conduct stakeholder analyses in the five countries participating in the Programme for Improving Mental health carE (PRIME); evaluate a template used for cross-country comparison of stakeholder analyses; and assess the utility of stakeholder analysis for future use in mental health policy and systems research in LMIC. Using an adapted stakeholder analysis instrument, PRIME country teams in Ethiopia, India, Nepal, South Africa and Uganda identified and characterised stakeholders in relation to the proposed action: scaling-up mental health services. Qualitative content analysis was conducted for stakeholder groups across countries, and a force field analysis was applied to the data. Stakeholder analysis of PRIME has identified policy makers (WHO, Ministries of Health, non-health sector Ministries and Parliament), donors (DFID UK, DFID country offices and other donor agencies), mental health specialists, the media (national and district) and universities as the most powerful, and most supportive actors for scaling up mental health care in the respective PRIME countries. Force field analysis provided a means of evaluating cross-country stakeholder power and positions, particularly for prioritising potential stakeholder engagement in the programme. Stakeholder analysis has been helpful as a research uptake management tool to identify targeted and acceptable strategies for stimulating the demand for research amongst knowledge users, including policymakers and practitioners. Implementing these strategies amongst stakeholders at a country level will hopefully reduce the knowledge gap between research and policy, and improve health system outcomes for the programme.

    2002-09-01

    This article presents preliminary findings from the first participant to complete an experiment assessing the efficacy of the personal stereo in treating auditory hallucinations. O.C., a 50-year-old woman, took part in a controlled treatment trial in which 1-week baseline, personal stereo, and control treatment (nonfunctioning hearing aid) stages were alternated for 7 weeks. The Positive and Negative Syndrome Scale, Clinical Global Impression Scales, Beliefs About Voices Questionnaire, Rosenberg Self-Esteem Scale, and Topography of Voices Rating Scale were used. The personal stereo led to a decrease in the severity of O.C.'s auditory hallucinations. For example, she rated her voices as being fairly distressing during baseline and control treatment stages but neutral during personal stereo stages. A slight decrease in other psychopathology also occurred during personal stereo stages. Use of the personal stereo did not lead to a decrease in self-esteem, contradicting suggestions that counterstimulation treatments for auditory hallucinations may be disempowering.

  9. Ultrasonic Techniques for Baseline-Free Damage Detection in Structures

    Science.gov (United States)

    Dutta, Debaditya

    This research presents ultrasonic techniques for baseline-free damage detection in structures in the context of structural health monitoring (SHM). Conventional SHM methods compare signals obtained from the pristine condition of a structure (baseline signals) with those from the current state, and relate certain changes in the signal characteristics to damage. While this approach has been successful in the laboratory, there are certain drawbacks of depending on baseline signals in real field applications. Data from the pristine condition are not available for most existing structures. Even if they are available, operational and environmental variations tend to mask the effect of damage on the signal characteristics. Most important, baseline measurements may become meaningless while assessing the condition of a structure after an extreme event such as an earthquake or a hurricane. Such events may destroy the sensors themselves and require installation of new sensors at different locations on the structure. Baseline-free structural damage detection can broaden the scope of SHM in the scenarios described above. A detailed discussion on the philosophy of baseline-free damage detection is provided in Chapter 1. Following this discussion, the research questions are formulated. The organization of this document and the major contributions of this research are also listed in this chapter. Chapter 2 describes a fully automated baseline-free technique for notch and crack detection in plates using a collocated pair of piezoelectric wafer transducers for measuring ultrasonic signals. Signal component corresponding to the damage induced mode-converted Lamb waves is extracted by processing the originally measured ultrasonic signals. The damage index is computed as a function of this mode-converted Lamb wave signal component. An over-determined system of Lamb wave measurements is used to find a least-square estimate of the measurement errors. This error estimate serves as the

    The initial phase of a pipeline integrity management program (IMP) is conducting a baseline assessment of the pipeline system and segments as part of Quantitative Risk Assessment (QRA). This gives the operator's integrity team the opportunity to identify critical areas and deficiencies in the protection, maintenance, and mitigation strategies. As a part of data gathering and integration of a wide variety of sources, in-line inspection (ILI) data is a key element. In order to move forward in the integrity program development and execution, the baseline geometry of the pipeline must be determined with accuracy and confidence. From this, all subsequent analysis and conclusions will be derived. Tuboscope Pipeline Services (TPS), in conjunction with Pipeway Engenharia of Brazil, operate ILI inertial navigation system (INS) and Caliper geometry tools, to address this integrity requirement. This INS and Caliper ILI tool data provides pipeline trajectory at centimeter level resolution and sub-metre 3D position accuracy along with internal geometry - ovality, dents, misalignment, and wrinkle/buckle characterization. Global strain can be derived from precise INS curvature measurements and departure from the initial pipeline state. Accurate pipeline elevation profile data is essential in the identification of sag/over bend sections for fluid dynamic and hydrostatic calculations. This data, along with pipeline construction, operations, direct assessment and maintenance data is integrated in LinaViewPRO{sup TM}, a pipeline data management system for decision support functions, and subsequent QRA operations. This technology provides the baseline for an informed, accurate and confident integrity management program. This paper/presentation will detail these aspects of an effective IMP, and experience will be presented, showing the benefits for liquid and gas pipeline systems. (author)

    Adding VLBI capability to the SKA arrays will greatly broaden the science of the SKA, and is feasible within the current specifications. SKA-VLBI can be initially implemented by providing phased-array outputs for SKA1-MID and SKA1-SUR and using these extremely sensitive stations with other radio telescopes, and in SKA2 by realising a distributed configuration providing baselines up to thousands of km, merging it with existing VLBI networks. The motivation for and the possible realization of SKA-VLBI is described in this paper.

    Important efforts have recently been dedicated to the improvement of the design of the baseline collimation system of the Compact Linear Collider (CLIC). Different aspects of the design have been optimized: the transverse collimation depths have been recalculated in order to reduce the collimator wakefield effects while maintaining a good efficiency in cleaning the undesired beam halo; the geometric design of the spoilers have also been reviewed to minimize wakefields; in addition, the optics design have been polished to improve the collimation efficiency. This paper describes the current status of the CLIC collimation system after this optimization.

    This study examined adult age differences in reflexive orienting to two types of uninformative spatial cues: central arrows and peripheral onsets. In two experiments using a Posner cuing task, young adults (ages 18 – 28 yrs), young-old adults (ages 60 – 74 yrs), and old-old adults (ages 75 – 92 yrs) responded to targets that were preceded 100–1,000 ms earlier by a central arrow or a peripheral abrupt onset. In Experiment 1, the cue remained present upon target onset. Facilitation effects at early cue-target stimulus onset asynchronies (SOAs) were prolonged in duration for the two older groups relative to the young adults. At later cue-target SOAs, inhibition of return (IOR) that was initiated by peripheral onset cues was observed in the performance of young adults but not in that of the two older groups. In Experiment 2, the cue was presented briefly and removed prior to target onset. The change in cue duration minimized age differences (particularly for young-old adults) in facilitation effects and led to IOR for all three age groups. The findings are consistent with the idea that attentional control settings change with age, with higher settings for older adults leading to delayed disengagement from spatial cues. PMID:21394555

    Agarwalla, Sanjib Kumar

    2014-01-01

    The discovery of neutrino mixing and oscillations over the past decade provides firm evidence for new physics beyond the Standard Model. Recently, theta13 has been determined to be moderately large, quite close to its previous upper bound. This represents a significant milestone in establishing the three-flavor oscillation picture of neutrinos. It has opened up exciting prospects for current and future long-baseline neutrino oscillation experiments towards addressing the remaining fundamental questions, in particular the type of the neutrino mass hierarchy and the possible presence of a CP-violating phase. Another recent and crucial development is the indication of non-maximal 2-3 mixing angle, causing the octant ambiguity of theta23. In this paper, I will review the phenomenology of long-baseline neutrino oscillations with a special emphasis on sub-leading three-flavor effects, which will play a crucial role in resolving these unknowns. First, I will give a brief description of neutrino oscillation phenomeno...

  19. Baseline and benchmark model development for hotels

    Science.gov (United States)

    Hooks, Edward T., Jr.

    The hotel industry currently faces rising energy costs and requires the tools to maximize energy efficiency. In order to achieve this goal a clear definition of the current methods used to measure and monitor energy consumption is made. Uncovering the limitations to the most common practiced analysis strategies and presenting methods that can potentially overcome those limitations is the main purpose. Techniques presented can be used for measurement and verification of energy efficiency plans and retrofits. Also, modern energy modeling tool are introduced to demonstrate how they can be utilized for benchmarking and baseline models. This will provide the ability to obtain energy saving recommendations and parametric analysis to explore energy savings potential. These same energy models can be used in design decisions for new construction. An energy model is created of a resort style hotel that over one million square feet and has over one thousand rooms. A simulation and detailed analysis is performed on a hotel room. The planning process for creating the model and acquiring data from the hotel room to calibrate and verify the simulation will be explained. An explanation as to how this type of modeling can potentially be beneficial for future baseline and benchmarking strategies for the hotel industry. Ultimately the conclusion will address some common obstacles the hotel industry has in reaching their full potential of energy efficiency and how these techniques can best serve them.

    2016-07-01

    [Purpose] This study investigated the effects of gait time and trunk acceleration ratio in old-old adult females during stair climbing. [Subjects and Methods] Twenty-five older adult females who were able to walk independently volunteered for this study and were categorized into two age groups (older adults or old-old adults). Gait time and trunk acceleration ratio were measured using an accelerometer during stair climbing. [Results] Gait time and trunk acceleration ratio when climbing stairs were significantly higher in the old-old age group than in the older adults group. [Conclusions] These findings suggest that old-old females have decreased upper trunk control. In addition, gait time and the trunk acceleration ratio during stair climbing are useful clinical markers for predicting function and balance control ability in old-old elderly populations.

  1. Different MMSE Score Is Associated with Postoperative Delirium in Young-Old and Old-Old Adults

    Background Postoperative delirium is one of the most common postoperative complications in geriatric patients. Mini-mental state examination (MMSE) assesses cognitive function in patients and is associated with postoperative delirium. However, whether there is an age-dependent relationship between preoperative MMSE score and postoperative delirium remains unknown. Methods We therefore set out to investigate the association between preoperative MMSE score and postoperative delirium in young-old (≤80 year-old, 75.46±4.69 years, 27.0% male, n = 63) and old-old (>80 year-old, 84.51±3.46 years, 20.9% male, n = 67) participants, who had repairs of hip fractures under general anesthesia. The Confusion Assessment Method and Memorial Delirium Assessment Scale were administrated before surgery, and on the first, second and fourth days after surgery, to assess the incidence and severity of the delirium, respectively. A receiver operating characteristic curve analysis was used to calculate the optimal cutoff score of MMSE in predicting postoperative delirium. Results Thirty-four (26.2%) of 130 patients (80.12±6.12 years, 23.8% male) developed postoperative delirium. Preoperative MMSE scores were negatively associated with higher incidences and greater severity of postoperative delirium. The optimal cutoff scores of MMSE associated with postoperative delirium for young-old and old-old participants were 18.4 and 21.4, with a sensitivity of 60% and 83.8%, and a specificity of 92.5% and 62.8%, respectively. Conclusion The data demonstrated the optimal cutoff score of MMSE associated with postoperative delirium in young-old adults might be lower than that in old-old adults. Pending further investigation, these findings suggest that the association between preoperative MMSE score and postoperative delirium is age-dependent. PMID:26460750

    Science.gov (United States)

    Roberts, D. H.

    1983-03-01

    With resolution of a thousandth of an arcsecond, the radio technique of Very Long Baseline Interferometry (VLBI) provides astronomers with their highest-resolution view of the universe. Data taken with widely-separated antennas are combined, with the help of atomic clocks, to form a Michelson interferometer whose size may be as great as the earth's diameter. Extraordinary phenomena, from the birth of stars as signaled by the brilliant flashes of powerful interstellar masers to the 'faster-than-light' expansion of the cores of distant quasars, are being explored with this technique. However, earth-bound VLBI suffers from several restrictions due to the location of the component antennas at fixed places on the earth's surface. The use of one or more antennas in space in concert with ground-based equipment will greatly expand the technical and scientific capabilities of VLBI, leading to a more complete and even higher resolution view of cosmic phenomena.

    OPERA is a long baseline neutrino oscillation experiment designed to observe the appearance of vτ in a pure vμ beam in the parameter space indicated by the atmospheric neutrinos oscillation signal. The detector is situated in the underground LNGS laboratory under 3 800 water meter equivalent at a distance of 730 km from CERN where the CNGS neutrino beam to which it is exposed originates. It consists of two identical 0.68 kilotons lead/nuclear emulsion targets, each instrumented with a tracking device and complemented by a muon spectrometer. The concept and the status of the detector are described and the first results obtained with cosmic rays and during two weeks of beam commissioning in 2006 are reported.

    2016-01-01

    The In-Space Manufacturing (ISM) project at NASA Marshall Space Flight Center currently operates a 3D FDM (fused deposition modeling) printer onboard the International Space Station. In order to enable utilization of this capability by designer, the project needs to establish characteristic material properties for materials produced using the process. This is difficult for additive manufacturing since standards and specifications do not yet exist for these technologies. Due to availability of crew time, there are limitations to the sample size which in turn limits the application of the traditional design allowables approaches to develop a materials property database for designers. In this study, various approaches to development of material databases were evaluated for use by designers of space systems who wish to leverage in-space manufacturing capabilities. This study focuses on alternative statistical techniques for baseline property development to support in-space manufacturing.

    The Pentek scabbling technology was tested at Florida International University (FIU) and is being evaluated as a baseline technology. This report evaluates it for safety and health issues. It is a commercially available technology and has been used for various projects at locations throughout the country. The Pentek concrete scabbling system consisted of the MOOSE{reg_sign}, SQUIRREL{reg_sign}-I, and SQUIRREL{reg_sign}-III scabblers. The scabblers are designed to scarify concrete floors and slabs using cross-section, tungsten carbide tipped bits. The bits are designed to remove concrete in 318 inch increments. The bits are either 9-tooth or demolition type. The scabblers are used with a vacuum system designed to collect and filter the concrete dust and contamination that is removed from the surface. The safety and health evaluation during the human factors assessment focused on two main areas: noise and dust.

  8. Steganography Based on Baseline Sequential JPEG Compression

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Information hiding in Joint Photographic Experts Group (JPEG) compressed images are investigated in this paper. Quantization is the source of information loss in JPEG compression process. Therefore, information hidden in images is probably destroyed by JPEG compression. This paper presents an algorithm to reliably embed information into the JPEG bit streams in the process of JPEG encoding. Information extraction is performed in the process of JPEG decoding. The basic idea of our algorithm is to modify the quantized direct current (DC) coefficients and non-zero alternating current (AC) coefficients to represent one bit information (0 or 1). Experimental results on gray images using baseline sequential JPEG encoding show that the cover images (images without secret information) and the stego-images (images with secret information) are perceptually indiscernible.

    Optical imaging with microarcsecond resolution will reveal details across and outside stellar surfaces but requires kilometer-scale interferometers, challenging to realize either on the ground or in space. Intensity interferometry, electronically connecting independent telescopes, has a noise budget that relates to the electronic time resolution, circumventing issues of atmospheric turbulence. Extents up to a few km are becoming realistic with arrays of optical air Cherenkov telescopes (primarily erected for gamma-ray studies), enabling an optical equivalent of radio interferometer arrays. Pioneered by Hanbury Brown and Twiss, digital versions of the technique have now been demonstrated, reconstructing diffraction-limited images from laboratory measurements over hundreds of optical baselines. This review outlines the method from its beginnings, describes current experiments, and sketches prospects for future observations.

    2011-01-01

    During the past decade, long-baseline neutrino experiments played a fundamental role in confirming neutrino flavor change and in measuring the neutrino mixing matrix with high precision. This role will be amplified with the next generation of experiments, which will begin probing the possibility of CP violation in the leptonic sector and possibly pin down the neutrino mass hierarchy. An account of the most recent results from the MINOS experiment is presented, along with the earlier measurement from the K2K experiment. The next generation projects, T2K and NOvA, are described and their current status, schedule and physics reach discussed. Finally, we report on future efforts, currently in the R&D stage, such as the LBNE and T2KK projects.

    2007-07-01

    WITCH - World Induced Technical Change Hybrid - is a regionally disaggregated hard link hybrid global model with a neoclassical optimal growth structure (top down) and an energy input detail (bottom up). The model endogenously accounts for technological change, both through learning curves affecting prices of new vintages of capital and through R and D investments. The model features the main economic and environmental policies in each world region as the outcome of a dynamic game. WITCH belongs to the class of Integrated Assessment Models as it possesses a climate module that feeds climate changes back into the economy. In this paper we provide a thorough discussion of the model structure and baseline projections. We report detailed information on the evolution of energy demand, technology and CO2 emissions. Finally, we explicitly quantifiy the role of free riding in determining the emissions scenarios. (auth)

    2015-01-01

    In a recent work by two of us, we have studied, how CP violation discovery potential can be improved at long baseline neutrino experiments (LBNE/DUNE), by combining with its ND (near detector) and reactor experiments. In this work, we discuss how this study can be further analysed to resolve entanglement of the quadrant of CPV phase and Octant of atmospheric mixing angle {\\theta}23, at LBNEs. The study is done for both NH (Normal hierarchy) and IH (Inverted hierarchy). We further show how leptogenesis can enhance this effect of resolving this entanglement. A detailed analytic and numerical study of baryogenesis through leptogenesis is performed in this framework in a model independent way. We then compare our result of the baryon to photon ratio with the the current observational data of the baryon asymmetry.

    2016-06-01

    This paper proposes a novel integrated navigation filter based on a combined long baseline/ultra short baseline acoustic positioning system with application to underwater vehicles. With a tightly coupled structure, the position, linear velocity, attitude, and rate gyro bias are estimated, considering the full nonlinear system dynamics without resorting to any algebraic inversion or linearisation techniques. The resulting solution ensures convergence of the estimation error to zero for all initial conditions, exponentially fast. Finally, it is shown, under simulation environment, that the filter achieves very good performance in the presence of sensor noise.

    This report presents biological baseline information gathered during the research project, Physical, Chemical and Biological Studies on Youngs Bay.'' Youngs Bay is a shallow embayment located on the south shore of the Columbia River, near Astoria, Oregon. Research on Youngs Bay was motivated by the proposed construction by Alumax Pacific Aluminum Corporation of an aluminum reduction plant at Warrenton, Oregon. The research was designed to provide biological baseline information on Youngs Bay in anticipation of potential harmful effects from plant effluents. The information collected concerns the kinds of animals found in the Youngs Bay area, and their distribution and seasonal patterns of abundance. In addition, information was collected on the feeding habits of selected fish species, and on the life history and behavioral characteristics of the most abundant benthic amphipod, Corophium salmonis. Sampling was conducted at approximately three-week intervals, using commonly accepted methods of animal collection. Relatively few stations were sampled for fish, because of the need to standardize conditions of capture. Data on fish capture are reported in terms of catch-per-unit effort by a particular sampling gear at a specific station. Methods used in sampling invertebrates were generally more quantitative, and allowed sampling at a greater variety of places, as well as a valid basis for the computation of densities. Checklists of invertebrate species and fish species were developed from these samples, and are referred to throughout the report. The invertebrate checklist is more specific taxonomically than are tables reporting invertebrate densities. This is because the methods employed in identification were more precise than those used in counts. 9 refs., 27 figs., 25 tabs.

    Rhabdomyolysis is defined as skeletal muscle necrosis. Ultrasound assessment has recently become a useful tool for the diagnosis and monitoring of muscle diseases, including rhabdomyolysis. A case is presented on the ultrasound findings in a patient with rhabdomyolysis. To highlight the importance of ultrasound as an essential part in the diagnosis in rhabdomyolysis, to describe the ultrasound findings, and review the literature. A 30 year-old with post-traumatic rhabdomyolysis of both thighs. Ultrasound was performed using a Philips Sparq model with a high-frequency linear transducer (5-10MHz), in low-dimensional scanning mode (2D), in longitudinal and transverse sections at the level of both thighs. The images obtained showed disorganisation of the orientation of the muscle fibres, ground glass image, thickening of the muscular fascia, and the presence of anechoic areas. Ultrasound is a useful tool in the evaluation of rhabdomyolysis. Copyright © 2015 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    2013-01-01

    Using a Canadian student achievement assessment database, the Science Achievement Indicators Program (SAIP), and employing the Rasch partial credit measurement model, this study estimated the difficulties of items corresponding to the learning outcomes in the Pan-Canadian science curriculum framework and the latent abilities of students of grades 7, 8, 10, 11, 12 and OAC (Ontario Academic Course). The above estimates serve as baselines for validating the Pan-Canadian science curriculum framework in terms of the learning progression of learning outcomes and expected mastery of learning outcomes by grades. It was found that there was no statistically significant progression in learning outcomes from grades 4-6 to grades 7-9, and from grades 7-9 to grades 10-12; the curriculum framework sets mastery expectation about 2 grades higher than students' potential abilities. In light of the above findings, this paper discusses theoretical issues related to deciding progression of learning outcomes and setting expectation of student mastery of learning outcomes, and highlights the importance of using national assessment data to establish baselines for the above purposes. This paper concludes with recommendations for further validating the Pan-Canadian science curriculum frameworks.

  18. Does Baseline Heart Rate Variability Reflect Stable Positive Emotionality?

    2014-11-01

    Several recent studies have found significant correlations, medium in effect size, between baseline heart rate variability (HRV) and measures of positive functioning, such as extraversion, agreeableness, and trait positive affectivity. Other research, however, has suggested an optimal level of HRV and found nonlinear effects. In the present study, a diverse sample of 239 young adults completed a wide range of measures that reflect positive psychological functioning, including personality traits, an array of positive emotions (measured with the Dispositional Positive Emotions Scale), and depression, anxiety, and stress symptoms (measured with the DASS and CESD). HRV was measured with a 6-minute baseline period and quantified using many common HRV metrics (e.g., respiratory sinus arrhythmia, root mean square of successive differences, and others), and potentially confounding behavioral and lifestyle variables (e.g., BMI, caffeine and nicotine use, sleep quality) were assessed. Neither linear nor non-linear effects were found, and the effect sizes were small and near zero. The findings suggest that the cross-sectional relationship between HRV and positive experience deserves more attention and meta-analytic synthesis.

  19. A baseline for the multivariate comparison of resting state networks

    2011-02-01

    Full Text Available As the size of functional and structural MRI datasets expands, it becomes increasingly important to establish a baseline from which diagnostic relevance may be determined, a processing strategy that efficiently prepares data for analysis, and a statistical approach that identifies important effects in a manner that is both robust and reproducible. In this paper, we introduce a multivariate analytic approach that optimizes sensitivity and reduces unnecessary testing. We demonstrate the utility of this mega-analytic approach by identifying the effects of age and gender on the resting state networks of 603 healthy adolescents and adults (mean age: 23.4 years, range: 12 to 71 years. Data were collected on the same scanner, preprocessed using an automated analysis pipeline based in SPM, and studied using group independent component analysis. Resting state networks were identified and evaluated in terms of three primary outcome measures: time course spectral power, spatial map intensity, and functional network connectivity. Results revealed robust effects of age on all three outcome measures, largely indicating decreases in network coherence and connectivity with increasing age. Gender effects were of smaller magnitude but suggested stronger intra-network connectivity in females and more inter-network connectivity in males, particularly with regard to sensorimotor networks. These findings, along with the analysis approach and statistical framework described here, provide a useful baseline for future investigations of brain networks in health and disease.

    Parents commonly label objects on television and for some programs, verbal labels are also provided directly via voice-over. The present study investigated whether toddlers' imitation performance from television would be facilitated if verbal labels were presented on television via voice-over or if they were presented by parents who were co-viewing with their toddlers. Sixty-one 2-year olds were randomly assigned to one of four experimental groups (voice-over video, parent video, parent video no label, parent live) or to a baseline control condition. Toddlers were tested with novel objects after a 24h delay. Although, all experimental groups imitated significantly more target actions than the baseline control group, imitation was facilitated by novel labels regardless of whether those labels were provided by parents or by voice-over on television. These findings have important implications for toddler learning from television.

    This report describes the test results and evaluation for the Phase 1 (baseline) arc melter vitrification test series conducted for the Buried Waste Integrated Demonstration program (BWID). Phase 1 tests were conducted on surrogate mixtures of as-incinerated wastes and soil. Some buried wastes, soils, and stored wastes at the INEL and other DOE sites, are contaminated with transuranic (TRU) radionuclides and hazardous organics and metals. The high temperature environment in an electric arc furnace may be used to process these wastes to produce materials suitable for final disposal. An electric arc furnace system can treat heterogeneous wastes and contaminated soils by (a) dissolving and retaining TRU elements and selected toxic metals as oxides in the slag phase, (b) destroying organic materials by dissociation, pyrolyzation, and combustion, and (c) capturing separated volatilized metals in the offgas system for further treatment. Structural metals in the waste may be melted and tapped separately for recycle or disposal, or these metals may be oxidized and dissolved into the slag. The molten slag, after cooling, will provide a glass/ceramic final waste form that is homogeneous, highly nonleachable, and extremely durable. These features make this waste form suitable for immobilization of TRU radionuclides and toxic metals for geologic timeframes. Further, the volume of contaminated wastes and soils will be substantially reduced in the process.

    Aims. An efficient means of locating calibrator sources for International LOFAR is developed and used to determine the average density of usable calibrator sources on the sky for subarcsecond observations at 140 MHz. Methods. We used the multi-beaming capability of LOFAR to conduct a fast and computationally inexpensive survey with the full International LOFAR array. Sources were pre-selected on the basis of 325 MHz arcminute-scale flux density using existing catalogues. By observing 30 different sources in each of the 12 sets of pointings per hour, we were able to inspect 630 sources in two hours to determine if they possess a sufficiently bright compact component to be usable as LOFAR delay calibrators. Results. Over 40% of the observed sources are detected on multiple baselines between international stations and 86 are classified as satisfactory calibrators. We show that a flat low-frequency spectrum (from 74 to 325 MHz) is the best predictor of compactness at 140 MHz. We extrapolate from our sample to sho...

    Lorentz symmetry violations can be described by an effective field theory framework that contains both general relativity and the Standard Model of particle physics called the Standard Model extension (SME). Recently, postfit analysis of Gravity Probe B and binary pulsars led to an upper limit at the 10-4 level on the time-time coefficient s¯T T of the pure-gravity sector of the minimal SME. In this work, we derive the observable of very long baseline interferometry (VLBI) in SME and then implement it into a real data analysis code of geodetic VLBI observations. Analyzing all available observations recorded since 1979, we compare estimates of s¯T T and errors obtained with various analysis schemes, including global estimations over several time spans, and with various Sun elongation cutoff angles, and by analysis of radio source coordinate time series. We obtain a constraint on s¯ T T=(-5 ±8 )×10-5 , directly fitted to the observations and improving by a factor of 5 previous postfit analysis estimates.

    1996-01-01

    An ultrafast, high precision gated integrator includes an opamp having differential inputs. A signal to be integrated is applied to one of the differential inputs through a first input network, and a signal indicative of the DC offset component of the signal to be integrated is applied to the other of the differential inputs through a second input network. A pair of electronic switches in the first and second input networks define an integrating period when they are closed. The first and second input networks are substantially symmetrically constructed of matched components so that error components introduced by the electronic switches appear symmetrically in both input circuits and, hence, are nullified by the common mode rejection of the integrating opamp. The signal indicative of the DC offset component is provided by a sample and hold circuit actuated as the integrating period begins. The symmetrical configuration of the integrating circuit improves accuracy and speed by balancing out common mode errors, by permitting the use of high speed switching elements and high speed opamps and by permitting the use of a small integrating time constant. The sample and hold circuit substantially eliminates the error caused by the input signal baseline offset during a single integrating window.

    What did coral reef ecosystems look like before human impacts became pervasive? Early efforts to reconstruct baselines resulted in the controversial suggestion that pristine coral reefs have inverted trophic pyramids, with disproportionally large top predator biomass. The validity of the coral reef inverted trophic pyramid has been questioned, but until now, was not resolved empirically. We use data from an eight-year tag-recapture program with spatially explicit, capture-recapture models to re-examine the population size and density of a key top predator at Palmyra atoll, the same location that inspired the idea of inverted trophic biomass pyramids in coral reef ecosystems. Given that animal movement is suspected to have significantly biased early biomass estimates of highly mobile top predators, we focused our reassessment on the most mobile and most abundant predator at Palmyra, the grey reef shark (Carcharhinus amblyrhynchos). We estimated a density of 21.3 (95% CI 17.8, 24.7) grey reef sharks/km2, which is an order of magnitude lower than the estimates that suggested an inverted trophic pyramid. Our results indicate that the trophic structure of an unexploited reef fish community is not inverted, and that even healthy top predator populations may be considerably smaller, and more precarious, than previously thought.

    Air quality and meteorological data collected at Fermi National Accelerator Laboratory are presented. The data represent baseline values for the pre-construction phase of a proposed coal-gasification test facility. Air quality data were characterized through continuous monitoring of gaseous pollutants, collection of meteorological data, data acquisition and reduction, and collection and analysis of discrete atmospheric samples. Seven air quality parameters were monitored and recorded on a continuous real-time basis: sulfur dioxide, ozone, total hydrocarbons, nonreactive hydrocarbons, nitric oxide, nitrogen oxides, and carbon monoxide. A 20.9-m tower was erected near Argonne's mobile air monitoring laboratory, which was located immediately downwind of the proposed facility. The tower was instrumented at three levels to collect continuous meteorological data. Wind speed was monitored at three levels; wind direction, horizontal and vertical, at the top level; ambient temperature at the top level; and differential temperature between all three levels. All continuously-monitored parameters were digitized and recorded on magnetic tape. Appropriate software was prepared to reduce the data. Statistical summaries, grphical displays, and correlation studies also are presented.

    In the face of increasing antimicrobial resistance and the paucity of new antimicrobial agents it has become clear that new antimicrobial strategies are urgently needed. One of these is to revisit old antibiotics to ensure that they are used correctly and to their full potential, as well as to determine whether one or several of them can help alleviate the pressure on more recent agents. Strategies are urgently needed to 're-develop' these drugs using modern standards, integrating new knowledge into regulatory frameworks and communicating the knowledge from the research bench to the bedside. Without a systematic approach to re-developing these old drugs and rigorously testing them according to today's standards, there is a significant risk of doing harm to patients and further increasing multidrug resistance. This paper describes factors to be considered and outlines steps and actions needed to re-develop old antibiotics so that they can be used effectively for the treatment of infections.

To investigate the changing expectations of old age throughout the life course, this paper draws on longitudinal interviews with immigrant women from Turkey who live in Denmark.

    Charles, D C; Charles, L A

    Charles Dickens, rare among authors of any period, presented a host of elderly and old characters in his novels and stories. More than 120 such characters were identified, distributed among four levels of involvement (protagonist to minor role) and six categories of behavior (warm and sympathetic to villainous and threatening). The two-thirds male, one-third female characters tended to be concentrated at the minor, rather than major, levels of involvement in plots, but they represented a great range of behavior. Dickens' old people were fully engaged in life and society and were not age-stereotyped.

    Short-baseline neutrino oscillations can have a relatively big effect on long-baseline oscillations, due to the cross terms that arise from multiple mass scales. The existing short-baseline anomalies suggest that short-baseline oscillations can affect the ν{sub μ} → ν{sub e} appearance probabilities by up to 20-40%, depending on the values of the CP-violating parameters.

Our WIYN 3.5m data set spans a time baseline of 11 years, a magnitude range of 12<=V<=16.5 (1.18-0.94 MSun), and a 1 deg. diameter region on the sky. With the addition of a Dominion Astrophysical Observatory (DAO) data set we extend our bright limit to V = 10.8 and, for some stars, extend our time baseline to 35 years. Our magnitude limits include solar-mass main-sequence stars, subgiants, giants, and blue stragglers (BSs), and our spatial coverage extends radially to 17 pc (~13 core radii). For the WIYN data we find a measurement precision of 0.4 km/s for narrow-lined stars. We have measured RVs for 1046 stars in the direction of NGC 188, finding 473 to be likely cluster members. We detect 124 velocity-variable cluster members, all of which are likely to be dynamically hard-binary stars. Using our single member stars, we find an average cluster RV of -42.36 +/- 0.04 km/s. We use our pre...

    We develop an accumulatively effective and affordable set of smart pair devices to save the exuberant expenditure for the healthcare of aging population, which will not be sustainable when all the post-war baby boomers retire (78 millions will cost 1/5~1/4 GDP in US alone). To design an accessible test-bed for distributed points of homecare, we choose two exemplars of the set to demonstrate the possibility of translation of modern military and clinical know-how, because two exemplars share identically the noninvasive algorithm adapted to the Smart Sensor-pairs for the real world persistent surveillance. Currently, the standard diagnoses for malignant tumors and diabetes disorders are blood serum tests, X-ray CAT scan, and biopsy used sometime in the physical checkup by physicians as cohort-average wellness baselines. The loss of the quality of life in making second careers productive may be caused by the missing of timeliness for correct diagnoses and easier treatments, which contributes to the one quarter of human errors generating the lawsuits against physicians and hospitals, which further escalates the insurance cost and wasteful healthcare expenditure. Such a vicious cycle should be entirely eliminated by building an "individual diagnostic aids (IDA)," similar to the trend of personalized drug, developed from daily noninvasive intelligent databases of the "wellness baseline profiling (WBP)". Since our physiology state undulates diurnally, the Nyquist anti-aliasing theory dictates a minimum twice-a-day sampling of the WBP for the IDA, which must be made affordable by means of noninvasive, unsupervised and unbiased methodology at the convenience of homes. Thus, a pair of military infrared (IR) spectral cameras has been demonstrated for the noninvasive spectrogram ratio test of the spontaneously emitted thermal radiation from a normal human body at 37°C temperature. This invisible self-emission spreads from 3 microns to 12 microns of the radiation wavelengths

  1. 1993 baseline solid waste management system description

    Armacost, L.L.; Fowler, R.A.; Konynenbelt, H.S.

    1994-02-01

    Pacific Northwest Laboratory has prepared this report under the direction of Westinghouse Hanford Company. The report provides an integrated description of the system planned for managing Hanford`s solid low-level waste, low-level mixed waste, transuranic waste, and transuranic mixed waste. The primary purpose of this document is to illustrate a collective view of the key functions planned at the Hanford Site to handle existing waste inventories, as well as solid wastes that will be generated in the future. By viewing this system as a whole rather than as individual projects, key facility interactions and requirements are identified and a better understanding of the overall system may be gained. The system is described so as to form a basis for modeling the system at various levels of detail. Model results provide insight into issues such as facility capacity requirements, alternative system operating strategies, and impacts of system changes (ie., startup dates). This description of the planned Hanford solid waste processing system: defines a baseline system configuration; identifies the entering waste streams to be managed within the system; identifies basic system functions and waste flows; and highlights system constraints. This system description will evolve and be revised as issues are resolved, planning decisions are made, additional data are collected, and assumptions are tested and changed. Out of necessity, this document will also be revised and updated so that a documented system description, which reflects current system planning, is always available for use by engineers and managers. It does not provide any results generated from the many alternatives that will be modeled in the course of analyzing solid waste disposal options; such results will be provided in separate documents.

    Full Text Available The process of demographic changes in Serbia is followed by discussions on the need to provide safety at old age and solve the problems of poverty and social exclusion of older citizens. In the current state there are no mechanisms that guarantee an adequate life standard at old age, the consequence of which is a high poverty rate, deteriorating health and limited access to social programs. The results of the Survey on life standard from 2002 and 2007 show that poverty among population in general and pensioners has decreased, while the poverty risk among people older than 65 has increased twice. The restrictive methods of the reforms cause a change in the relation between the pensions and the earnings, so that more and more pensioners receive below average, i.e. minimal pensions. Not all old people are covered by pension insurance so that a significant number (around 400.000 does not have a safe monthly income at all. The state program of financial aid is of modest size and does not provide help to all of the poor. Welfare aid decreases the risk of poverty, but it do not guarantee an adequate level of material security at old age. The low level of minimal and average pensions, the decline of participation in the average earnings and the strict criteria of the social security system have brought to awareness the necessity of 'social pensions' and various help and support programs for the elderly. .

    The proposed Long Baseline Neutrino Observatory (LBNO) initially consists of $\\sim 20$ kton liquid double phase TPC complemented by a magnetised iron calorimeter, to be installed at the Pyh\\"asalmi mine, at a distance of 2300 km from CERN. The conventional neutrino beam is produced by 400 GeV protons accelerated at the SPS accelerator delivering 700 kW of power. The long baseline provides a unique opportunity to study neutrino flavour oscillations over their 1st and 2nd oscillation maxima exploring the $L/E$ behaviour, and distinguishing effects arising from $\\delta_{CP}$ and matter. In this paper we show how this comprehensive physics case can be further enhanced and complemented if a neutrino beam produced at the Protvino IHEP accelerator complex, at a distance of 1160 km, and with modest power of 450 kW is aimed towards the same far detectors. We show that the coupling of two independent sub-MW conventional neutrino and antineutrino beams at different baselines from CERN and Protvino will allow to measure ...

  9. Long baseline neutrino physics: From Fermilab to Kamioka

    Energy Technology Data Exchange (ETDEWEB)

    DeJongh, Fritz

    2002-03-01

    We have investigated the physics potential of very long baseline experiments designed to measure nu_mu to nu_e oscillation probabilities. The principles of our design are to tune the beam spectrum to the resonance energy for the matter effect, and to have the spectrum cut off rapidly above this energy. The matter effect amplifies the signal, and the cut-off suppresses backgrounds which feed-down from higher energy. The signal-to-noise ratio is potentially better than for any other conventional nu_mu beam experiment. We find that a beam from Fermilab aimed at the Super-K detector has excellent sensitivity to sin^2(2theta_13) and the sign of Delta M^2. If the mass hierarchy is inverted, the beam can be run in antineutrino mode with a similar signal-to-noise ratio, and event rate 55% as high as for the neutrino mode. Combining the Fermilab beam with the JHF-Kamioka proposal adds very complementary information. We find good sensitivity to maximal CP violation for values of sin^2(2theta_13) ranging from 0.001 to 0.05.

  10. Old Age Stigmatization

    Gražina Rapolienė

    2015-01-01

    Full Text Available Surprisingly, the discourse on ageism hardly profits from stigma research despite their common denominator—discrimination. The goal of this article is to discuss the stigma concept developed on micro-level interactions and apply it to ageism research on the macro level, i.e. using Round 4 data of the representative international European Social Survey (2008. The data analysis is focused on dominant opinions of the Lithuanian population (N=2002 and usual behavior toward older people, while international comparison is used for interpretation of results. The results show that old age in the Lithuanian society is an “open secret” type of stigma: verbal praise of older people, high assessment of their morals and polite declaration of respect conceal intolerance, disregard and discrimination on the behavioral level. The old age stigma is widespread in Lithuania and stronger than in advanced European countries. Its level is close to discrimination particular to other post-communist and Mediterranean countries.

  12. Old-growth Policy

    Directory of Open Access Journals (Sweden)

    David M. Ostergren

    2007-12-01

    Full Text Available Most federal legislation and policies (e.g., the Wilderness Act, Endangered Species Act, National Forest Management Act fail to speak directly to the need for old-growth protection, recruitment, and restoration on federal lands. Various policy and attitudinal barriers must be changed to move beyond the current situation. For example, in order to achieve the goal of healthy old growth in frequent-fire forests, the public must be educated regarding the evolutionary nature of these ecosystems and persuaded that collaborative action rather than preservation and litigation is the best course for the future of these forests. Land managers and policy makers must be encouraged to look beyond the single-species management paradigm toward managing natural processes, such as fire, so that ecosystems fall within the natural range of variability. They must also see that, given their recent evidence of catastrophic fires, management must take place outside the wildland–urban interface in order to protect old-growth forest attributes and human infrastructure. This means that, in some wilderness areas, management may be required. Land managers, researchers, and policy makers will also have to agree on a definition of old growth in frequent-fire landscapes; simply adopting a definition from the mesic Pacific Northwest will not work. Moreover, the culture within the federal agencies needs revamping to allow for more innovation, especially in terms of tree thinning and wildland fire use. Funding for comprehensive restoration treatments needs to be increased, and monitoring of the Healthy Forest Initiative and Healthy Forest Restoration Act must be undertaken.

    Full Text Available Background: Iodine Deficiency Disorder (100 reduction program has been implemented since 1976. According to the National Economic Survey 2002, the average consumption of iodized salt was 6. 26 grams. The results of Iodine Salt Survey (SGY 2003 showed that the consumption of iodine salt at the household level was 73.2%, meanwhile, the baseline health survey (Riskesdas 2007 showed there was reduction of iodine salt consumption towards 60.2%. Methods: Type of study was secondary data analysis with cross-sectional design utilizing the Riskesdas 2007's data. Sample was selected purposively according to the previous SGY's survey based on the endemically criteria namely highly endemic, mediocre and non endemic. Results: The results of the analysis were there was discrepancy of iodine salt consumption among urban and rural areas as well as mother's education level. The iodine salt consumption was higher in the urban area (65.5% compare to the rural area (52.9%. The higher the education of mothers the better the iodine salt consumed. The usage of iodine salt in the households based on salt quick test was 60.2%, meanwhile, according to the salt titration it was only 23.4%. The results of Excretion Iodine Urine showed that the iodine intake among the school children (age of 6-12 years old was 12.8% and was still below the cut-off point prevalence, which is greater than 50%. The conclusion of this analysisis that there was evidence of iodine salt reduction consumed at the household level. Conversely, there was inclination of the percentage of iodine urine level among the school children in Indonesia in the year 2007. It is recommended that policy analysis need to be conducted due to the achievement of the Universal Salt iodization target, especially in the endemic areas to asses the existence of the IDO prevalence. Key words: Iodine salt at the households, Iodine salt consumption, urine iodine excretion

    2008-01-01

    We examine the reach of a Beta-beam experiment with two detectors at carefully chosen baselines for exploring neutrino mass parameters. Locating the source at CERN, the two detectors and baselines are: (a) a 50 kton iron calorimeter (ICAL) at a baseline of around 7150 km which is roughly the magic baseline, e.g., ICAL@INO, and (b) a 50 kton Totally Active Scintillator Detector at a distance of 730 km, e.g., at Gran Sasso. We choose 8B/8Li source ions with a boost factor \\gamma of 650 for the magic baseline while for the closer detector we consider 18Ne/6He ions with a range of Lorentz boosts. We find that the locations of the two detectors complement each other leading to an exceptional high sensitivity. With \\gamma=650 for 8B/8Li and \\gamma=575 for 18Ne/6He and total luminosity corresponding to 5\\times (1.1 \\times 10^{18}) and 5\\times (2.9\\times 10^{18}) useful ion decays in neutrino and antineutrino modes respectively, we find that our two detector set-up can probe maximal CP violation and establish the neu...

    stratospheric intrusion, and intensified continental export. The lowest baseline CO at Appledore Island (AI, PM, TF, PSP, WFM and the lowest baseline O3 at AI, PM, and PSP in summer 2009 were linked to the negative phase of the Arctic oscillation (AO, when more frequent cyclone activities brought more clean Arctic air to midlatitudes. It was also found that forest fires played a major role in determining baseline CO in the northeast US In summer, ~ 38% of baseline CO variability at AI, CS, MWO, TF, PSP, and WFM could be explained by CO emissions from forest fires in Russia and ~ 22 % by emissions from forest fires in Canada. Long-range transport of O3 and its precursors from biomass burning contributed to the highest baseline O3 in summer 2003 at AI, CS, MWO, TF, and WFM. The findings of this study suggested impacts of increasing Asian emissions, NOx emissions from the Northeast Urban corridor, global biomass burning emissions, and meteorological conditions (e.g. cyclone activity, AO, and NAO should all be considered when designing strategies for meeting and maintaining National Ambient Air Quality Standards (NAAQS and evaluating the air quality in the northeast US.

    AIM: To characterize the baseline profiles of patients aged 70 years and above with hepatocellular carcinoma (HCC).METHODS: A series of 127 consecutive patients with HCC were enrolled between 2000 and 2004, and none of them had been diagnosed as having HCC previously. Baseline profiles, including parameters of hepatic function such as serum transaminase and prothrombin time [PT (% activity)] were compared between patients aged ≥70 and <70 years.RESULTS: Patients ≥70 years old showed significantly lower levels of aspartate aminotransferase (P = 0.04)and alanine aminotransferase (P = 0.01), and significantly higher PTs (P= 0.04) and platelet counts (P = 0.02).Concomitantly, among ≥70-year-old patients, HCC was more common in non-cirrhotics, whereas among patients <70 years old, HCC was more common in cirrhotics. There was no significant difference between the groups in the number or size of tumors.CONCLUSION: Older HCC patients showed less inflammation and better preservation of hepatic function, indicating that not only cirrhotic patients but also noncirrhotic patients should be considered as a high-risk group among the elderly.

    Full Text Available Background. The aim of this study was to evaluate whether the decline of physical activity during winter influences physical performances (after 1 year in old-old women. Methods. Fifty-three Japanese women (mean age: 78.4 ± 3.2 years participated in this study. Data of physical activity was collected by using an accelerometer at baseline and 3-month follow-up, and participants who decreased step counts in this period were defined as declining groups. We measured grip strength, knee extensor strength, total length of the center of gravity, hip walking distance, and maximum walking speed to evaluate physical performances at baseline and 1-year follow-up. Repeated-measures analysis of variance determined the difference in physical performance between declining groups and maintenance group with maintained or improved step counts. Results. Daily step counts for 22 older women (41.5% decreased during winter. A statistically significant interaction effect between group and time was found for maximum walking speed (F(1,50=5.23, p=0.03. Post hoc comparisons revealed that walking speed in the maintenance group significantly increased compared with baseline (p=0.01; the declining group showed no significant change (p=0.44. Conclusion. Change of physical activity during winter influences the physical performance level after 1 year in community-dwelling old-old women, particularly its effect on maximum walking speed.

    Growing old as a woman. Since Diderot, a classic writer, and his friend Sophie Volland with whom he corresponded, debated the difference between the "handsome old man" and "beautiful old age", or a hypothetical "beautiful old woman", the representations of growing old have changed, to the benefit of women. Has the considerable contribution of female writers to the debate played a role? In what ways does literature, through its figurations of the ages of life, provide a valuable perspective of the contemporary mutations of the view of old age?

  3. Messianic expectations in the Old Testament

    Directory of Open Access Journals (Sweden)

    W. Rose

    2001-08-01

    Full Text Available The New Testament is connected to the Old Testament in a number of different ways. It is not unusual to find the word “messianic” used to categorise all the different ways in which the writers of the New Testament find Christ (and, similarly, Jewish sources of the Second Temple Period later find the future Messiah in the Old Testament, or to identify the specific passages in the Old Testament which are now seen to point to Christ/the Messiah. In this article I argue that, if one wants to be able to appreciate the diversity, one should abandon this indiscriminate use of the word “messianic”. After a brief discussion of the meaning and use of the Hebrew word xyvm in the Old Testament, I propose a definition of the phrase “messianic expectations” (expectations focusing on a future royal figure sent by God – someone who will bring salvation to God’s people and the world and establish a kingdom characterised by features such as peace and justice. Subsequently, the origin of these expectations is located as in the proclamation of the eighth-century prophets (Amos, Isaiah and Micah. Finally, one special category of messianic expectations, that is, messianic expectations in the Books of the Psalms, is dealt with.

Although no bone metastases were found, there was abnormal uptake noted in the liver corresponding to a metastatic calcified lesion. The only other findings were of degenerative disease in the cervical spine, right shoulder and small joints of the hands. A 69-year-old male with carcinoma of the prostate and right side low back pain was referred for bone scan. No focal abnormalities to suggest metastatic disease were identified; findings within the cervical spine, lumber spine and knees were presumed secondary to degenerative disease. Intermittent pain persisted and the patient was referred for a repeat bone scan six months later. Previous scan findings of degenerative disease and no metastatic disease were confirmed; however, closer inspection revealed an enlarged right kidney with significant retention of tracer in the pelvicalyceal system suggesting possible obstruction. A Retrograde pyelogram was performed, and no obvious obstruction demonstrated. As bone scan findings were very suggestive of obstruction, a DTPA scan with lasix was performed showing a dilated right collecting system with no functional obstruction. Given the degree of dilation, it is possible that the patient experiences intermittent PUJ obstruction causing his symptoms. A 33-year-old male with insulin dependent diabetes mellitus and viral arthritis was referred for a bone scan. A three phase revealed increased uptake in the region of the knee and leR proximal tibia. Delayed whole body images revealed multiple focal areas of osteoblastic activity in the leR tibia. Abnormal uptake was also seen in the upper third of the leR femur. The remainder of the skeletal survey was normal. X-ray correlation of the leR tibia and femoral findings was undertaken. Combinating unilateral changes on bone scan and X-ray although very suggestive of sclerotic polyostotic

    Full Text Available Nowadays everybody is getting puzzled and confused about choosing right oil for daily use. Most of the ads in the market revolving around sunflower oil only with different brand names claiming it is heart friendly. In recent years, younger generation may not be familiar much with our age old traditional oils like sesame oil. Sesame oil is also called as gingelly oil or til oil is rich in vitamin E and B. It is a good source of minerals like calcium, manganese and phosphorous and promotes healing. It contains high amounts of polyunsaturated fatty acids and decreases high blood pressure. Because of its antioxidant property, it decreases cholesterol and good for heart. It acts like a sedative, relieves mental fatigue and promotes sleep when it is used for head massage. It is having laxative nature, relieving constipation. When applied topically on to the skin it is acting as an excellent moisturizer and an emollient. Because of its natural antibacterial, antiviral and anti-inflammatory properties it keeps away the skin and tooth infections. Hence, it can be used by one and all without any hesitation for regular cooking. However, it is not preferred for deep frying. Let us once again say OLD IS GOLD

    Full Text Available BACKGROUND: Late diagnosis of HIV infection is common. We aim to assess the proportion of newly diagnosed HIV cases receiving timely baseline CD4 count testing and the associated factors in China. METHODS: Data were extracted from the Chinese HIV/AIDS Comprehensive Response Information Management System. Adult patients over 15 years old who had been newly diagnosed with HIV infection in China between 2006 and 2012 were identified. The study cohort comprised individuals who had a measured baseline CD4 count. RESULTS: Among 388,496 newly identified HIV cases, the median baseline CD4 count was 294 cells/µl (IQR: 130-454, and over half (N = 130,442, 58.8% were less than 350 cells/µl. The median baseline CD4 count increased from 221 (IQR: 63-410 in 2006 to 314 (IQR: 159-460 in 2012. A slight majority of patients (N = 221,980, 57.1% received baseline CD4 count testing within 6 months of diagnosis. The proportion of individuals who received timely baseline CD4 count testing increased significantly from 20.0% in 2006 to 76.9% in 2012. Factors associated with failing to receiving timely CD4 count testing were: being male (OR: 1.17, 95% CI: 1.15-1.19, age 55 years or older (OR:1.03, 95% CI: 1.00-1.06, educational attainment of primary school education or below (OR: 1.30, 95% CI: 1.28-1.32, infection with HIV through injection drug use (OR: 2.07, 95% CI: 2.02-2.12 or sexual contact and injection drug use (OR: 1.87, 95% CI: 1.76-1.99, diagnosis in a hospital (OR: 1.91, 95% CI: 1.88-1.95 or in a detention center (OR: 1.75, 95% CI: 1.70-1.80, and employment as a migrant worker (OR:1.55, 95% CI:1.53-1.58. CONCLUSION: The proportion of newly identified HIV patients receiving timely baseline CD4 testing has increased significantly in China from 2006-2012. Continued effort is needed for further promotion of early HIV diagnosis and timely baseline CD4 cell count testing.

    GLoBES (General Long Baseline Experiment Simulator) is a flexible software package to simulate neutrino oscillation long baseline and reactor experiments. On the one hand, it contains a comprehensive abstract experiment definition language (AEDL), which allows to describe most classes of long baseline experiments at an abstract level. On the other hand, it provides a C-library to process the experiment information in order to obtain oscillation probabilities, rate vectors, and Δχ-values. Currently, GLoBES is available for GNU/Linux. Since the source code is included, the port to other operating systems is in principle possible. GLoBES is an open source code that has previously been described in Computer Physics Communications 167 (2005) 195 and in Ref. [7]). The source code and a comprehensive User Manual for GLoBES v3.0.8 is now available from the CPC Program Library as described in the Program Summary below.

    Coral reefs are some of the most diverse and valuable ecosystems in the world. Vital for maintaining ecological balance in coastal tropical environments, they also stand as the foundation for enormous cultural and economic resources. However, the continued degradation of coral reefs around the world, particularly within NOAA's Hawaii Marine Sanctuary, is an alarming call for action towards the identification of stressors and subsequent rehabilitation of these national treasures. Aligned with the goals of NOAA's National Marine Sanctuary to protect areas of the marine environment that are of special national significance to cultural, scientific, educational, and ecological values, this research targets addressing and standardizing antioxidant enzyme stress levels in Hawaiian coral over reproductive cycles in order to increase management aptitude and efficiency. By developing a greater understanding for biochemical biomarkers of stress in corals, specifically through the study of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase activity and expression, my research will aid in the adaptation and further development of biochemical tests to understand baseline thresholds of stress on coral reefs within Sanctuary waters. Slight, but significant variations in enzyme expression over reproductive time points alert us to modifications that must be made to consider fluctuating levels of coral susceptibility when sampling corals under stress. These findings will be applied to diagnostic tests describing the effect of different chemical pollutants on coral health in order to identify ecological issues and expand the knowledge of local communities and NOAA, so that steps can be taken to mitigate human Sanctuary impacts.

  9. Constraints on New Physics from Long Baseline Neutrino Oscillation Experiments

    2007-01-01

    New physics beyond the Standard Model can lead to extra matter effects on neutrino oscillation if the new interactions distinguish among the three flavors of neutrino. In a previous paper, we argued that a long-baseline neutrino oscillation experiment in which the Fermilab-NUMI beam in its high-energy mode is aimed at the planned Hyper-Kamiokande detector would be capable of constraining the size of those extra effects, provided the vacuum value of \\sin^2 2\\theta_{23} is not too close to one. In this paper, we discuss how such a constraint would translate into limits on the coupling constants and masses of new particles in various models. The models we consider are: models with generation distinguishing Z's such as topcolor assisted technicolor, models containing various types of leptoquarks, R-parity violating SUSY, and extended Higgs sector models. In several cases, we find that the limits thus obtained could be competitive with those expected from direct searches at the LHC. In the event that any of the pa...

    It is found that the minimum detectable activity (MDA) has a same tendency as the relative standard deviation (RSD) and a particular application is characteristic of the ratio of the peak area to the baseline height. Different applications need different algorithms to reduce the RSD of peak areas or the MDA of potential peaks. A model of Gaussian peaks superposed on linear baselines is established to simulate the multichannel spectrum and summing-up algorithms such as total peak area (TPA), and Covell and Sterlinski are compared to find the most appropriate algorithm for different applications. The results show that optimal Covell and Sterlinski algorithms will yield MDA or RSD half lower than TPA when the areas of small peaks on high baselines are to be determined. The conclusion is proved by experiment.

    It is critically important in any improvement activity to first understand the organization's current status, strengths, and weaknesses and, only after that understanding is achieved, examine and implement promising improvements. This fundamental rule is certainly true for an organization seeking to further its software viability and effectiveness. This paper addresses the role of the organizational process baseline in a software improvement effort and the lessons we learned assembling such an understanding for NASA overall and for the NASA Goddard Space Flight Center in particular. We discuss important, core data that must be captured and contrast that with our experience in actually finding such information. Our baselining efforts have evolved into a set of data gathering, analysis, and crosschecking techniques and information presentation formats that may prove useful to others seeking to establish similar baselines for their organization.

    The present work deals with the development of a new baseline correction method based on the comparative learning capabilities of artificial neural networks. The developed method uses the Bayes probability theorem for prevention of the occurrence of the over-fitting and finding a generalized baseline. The developed method has been applied on simulated and real metabolomic gas-chromatography (GC) and Raman data sets. The results revealed that the proposed method can be used to handle different types of baselines with cave, convex, curvelinear, triangular and sinusoidal patterns. For further evaluation of the performances of this method, it has been compared with benchmarking baseline correction methods such as corner-cutting (CC), morphological weighted penalized least squares (MPLS), adaptive iteratively-reweighted penalized least squares (airPLS) and iterative polynomial fitting (iPF). In order to compare the methods, the projected difference resolution (PDR) criterion has been calculated for the data before and after the baseline correction procedure. The calculated values of PDR after the baseline correction using iBRANN, airPLS, MPLS, iPF and CC algorithms for the GC metabolomic data were 4.18, 3.64, 3.88, 1.88 and 3.08, respectively. The obtained results in this work demonstrated that the developed iterative Bayesian regularized neural network (iBRANN) method in this work thoroughly detects the baselines and is superior over the CC, MPLS, airPLS and iPF techniques. A graphical user interface has been developed for the suggested algorithm and can be used for easy implementation of the iBRANN algorithm for the correction of different chromatography, NMR and Raman data sets.

    Carter, Jacqueline C; Kelly, Allison C

    2015-03-01

    This study aimed to identify baseline predictors of autonomous and controlled motivation for treatment (ACMT) in a transdiagnostic eating disorder sample, and to examine whether ACMT at baseline predicted change in eating disorder psychopathology during treatment. Participants were 97 individuals who met DSM-IV-TR criteria for an eating disorder and were admitted to a specialized intensive treatment programme. Self-report measures of eating disorder psychopathology, ACMT, and various psychosocial variables were completed at the start of treatment. A subset of these measures was completed again after 3, 6, 9, and 12 weeks of treatment. Multiple regression analyses showed that baseline autonomous motivation was higher among patients who reported more self-compassion and more received social support, whereas the only baseline predictor of controlled motivation was shame. Multilevel modelling revealed that higher baseline autonomous motivation predicted faster decreases in global eating disorder psychopathology, whereas the level of controlled motivation at baseline did not. The current findings suggest that developing interventions designed to foster autonomous motivation specifically and employing autonomy supportive strategies may be important to improving eating disorders treatment outcome. The findings of this study suggest that developing motivational interventions that focus specifically on enhancing autonomous motivation for change may be important for promoting eating disorder recovery. Our results lend support for the use of autonomy supportive strategies to strengthen personally meaningful reasons to achieve freely chosen change goals in order to enhance treatment for eating disorders. One study limitation is that there were no follow-up assessments beyond the 12-week study and we therefore do not know whether the relationships that we observed persisted after treatment. Another limitation is that this was a correlational study and it is therefore important

    2012-06-01

    Full Text Available Abstract Background The impedance baseline has been shown to reflect esophageal integrity, and to be decreased in patients with esophagitis. However, different methods for the determination of the impedance baseline have not been compared. Methods The median impedance baseline was calculated in 10 consecutive multichannel intraluminal impedance recordings in children with non-erosive reflux disease. All children underwent an endoscopy with a biopsy as part of the clinical work-up to exclude esophagitis. The impedance baseline was obtained both by including and excluding all impedance episodes (IE; reflux, swallows and gas episodes during the full recording, and during the first 1-minute period without an IE every hour (method 1, every 2 hours (method 2 or every 4 hours (method 3. The impedance baseline obtained during the full recording was set at 100%, and the variation (difference in impedance baseline for the different methods and variability (difference in impedance baseline during one analysis period were assessed. Results None of the participants had esophagitis. The mean difference over the six channels between the impedance baseline over the total recording with and without IE was approximately 2.5%, and comparable for each channel (range 0.47% to 5.55%. A mean of 1,028 IEs were excluded in each tracing, and it took between 4 and 24 hours to delete all events in one tracing. The difference in the impedance baseline obtained with and without IEs was mainly caused by the gas episodes in the upper channels and swallows in the lower channels. The median impedance baseline according to the three one-minute analysis methods was comparable to the median impedance baseline according to the 24 hour analysis. Conclusions The automatic determination of the median impedance baseline over the total tracing including IEs is an adequate method. In isolated tracings with numerous IEs, the calculation of the median impedance baseline over one minute

    Full Text Available In his final unfinished book on the writing of history, Siegfried Kracauer wonders about his increasing susceptibility to ‘the speechless plea of the dead’. ‘[T]he older one grows, the more he is bound to realize that his future is the future of the past—history.’ For the children of migrants, the question of how to speak well of the dead is distinguished by complex feelings of attachment and rejection, identification and denial that are expressed in a range of everyday interactions. ‘The Old Greeks’ examines the part played by photographic media in this process of memorialisation. It elaborates a series of propositions about the value of photographic media that are tested through a consideration of the events that surrounded the author’s first years in Australia.

    No studies have been conducted yet into the effectiveness of treatment of personality disorders in later life. This study is a first test of the effectiveness of schema therapy for personality disorders in older adults. Multiple-baseline design with eight cluster C personality disorder patients, with a mean age of   69. After a baseline phase with random length, schema therapy was given during the first year, followed by follow-up sessions during six months. Participants weekly rated the credibility of dysfunctional core beliefs. Symptomatic distress, early maladaptive schemas, quality of life and target complaints were assessed every six months and personality disorder diagnosis was assessed before baseline and after follow-up. Data were analyzed with mixed regression analyses. Results revealed significant linear trends during treatment phases, but not during baseline and follow-up. The scores during follow-up remained stable and were significantly lower compared to baseline, with high effect sizes. Seven participants remitted from their personality disorder diagnosis. Schema therapy appears an effective treatment for cluster C personality disorders in older adults. This finding is highly innovative as this is the first study exploring the effectiveness of psychotherapy, in this case schema therapy, for personality disorders in older adults.

    2016-01-01

    Assuming that there is a sterile neutrino, we ask what then is the ability of long-baseline experiments to i) establish that neutrino oscillation violates CP, ii) determine the three-neutrino mass ordering, and iii) determine which CP-violating phase or phases are the cause of any CP violation that may be observed. We find that the ability to establish CP violation and to determine the mass ordering could be very substantial. However, the effects of the sterile neutrino could be quite large, and it might prove very difficult to determine which phase is responsible for an observed CP violation. We explain why a sterile neutrino changes the long-baseline sensitivities to CP violation and to the mass ordering in the ways that it does. We note that long-baseline experiments can probe the presence of sterile neutrinos in a way that is different from, and complementary to, the probes of short-baseline experiments. We explore the question of how large sterile-active mixing angles need to be before long-baseline expe...

    C.J. Albert, the head of family-owned Armor Coat Insurance, is just settling in on a Sunday evening when the receives an unsettling phone call from his star salesman. Fifty-two-year-old Ed McGlynn has just returned from a business dinner with his younger technology mentor, and he's none too happy with the way he's being treated. If C.J. doesn't take this attack dog off him, Ed warns, he's gone. C.J. had indeed assigned 28-year-old Roger Sterling--the company's monomaniacal, slightly antisocial director of e-commerce--to teach Ed about digital strategy and the Web. Reverse mentoring seemed like a good way to create synergy between the sales and technology groups. The goal was to create a digital insurance product that would allow Armor Coat to keep up with its competitors. But there'd been tension between Ed and Roger right from the start--stemming from their personalities and their two departments. So when the two reluctantly agreed to meet for dinner to talk, the conversation didn't go well. Ed insisted that great sales reps, not the Internet, are crucial to selling insurance. Roger insisted that the Web will revolutionize the way insurance is sold and distributed--that Ed either give in or move on. Ed took off in a huff and subsequently phoned C.J. Roger followed Ed's irate call with his own weary ultimatum: "Either Ed goes or I go." C.J. faces some difficult Monday-morning discussions with both disgruntled parties. What should he do? Six commentators, including a mentor-protégé pair, offer their advice in this fictional case study.

  10. Establishing a store baseline during interim storage of waste packages and a review of potential technologies for base-lining

    Interim storage is an essential component of the waste management lifecycle, providing a safe, secure environment for waste packages awaiting final disposal. In order to be able to monitor and detect change or degradation of the waste packages, storage building or equipment, it is necessary to know the original condition of these components (the 'waste storage system'). This paper presents an approach to establishing the baseline for a waste-storage system, and provides guidance on the selection and implementation of potential base-lining technologies. The approach is made up of two sections; assessment of base-lining needs and definition of base-lining approach. During the assessment of base-lining needs a review of available monitoring data and store/package records should be undertaken (if the store is operational). Evolutionary processes (affecting safety functions), and their corresponding indicators, that can be measured to provide a baseline for the waste-storage system should then be identified in order for the most suitable indicators to be selected for base-lining. In defining the approach, identification of opportunities to collect data and constraints is undertaken before selecting the techniques for base-lining and developing a base-lining plan. Base-lining data may be used to establish that the state of the packages is consistent with the waste acceptance criteria for the storage facility and to support the interpretation of monitoring and inspection data collected during store operations. Opportunities and constraints are identified for different store and package types. Technologies that could potentially be used to measure baseline indicators are also reviewed. (authors)

LARG knockdown resulted in 12-week-old SHRs showing the greatest reduction in aortic ring contraction.Conclusion: There were differences in age-related RhoGEF expression at baseline and in response to Ang II stimulation between SHRs and WKY rats in this study. Nanotechnology can assist in studying the silencing of LARG in tissue culture. The findings of this study indicate that LARG gene expression may be associated with the genesis of hypertension in SHRs.Keywords: Rho guanine nucleotide exchange factor, leukemia-associated Rho guanine nucleotide exchange factor, Wistar-Kyoto rats, nanoparticle delivery, hypertension

    2008-01-01

    We discuss the prospects of exploring the neutrino mass parameters with a CERN based Beta-beam experiment using two different detectors at two different baselines. The proposed set-up consists of a 50 kton iron calorimeter (ICAL) at a baseline of around 7150 km which is roughly the magic baseline, e.g., ICAL@INO, and a 50 kton Totally Active Scintillator Detector at a distance of 730 km, e.g., at Gran Sasso. We take 8B and 8Li source ions with a boost factor $\\gamma$ of 650 for the magic baseline while for the closer detector we consider 18Ne and 6He ions with a range of Lorentz boosts. We find that the locations of the two detectors complement each other leading to an exceptional high sensitivity. With $\\gamma=650$ for 8B/8Li and $\\gamma=575$ for 18Ne/6He and total luminosity corresponding to $5\\times (1.1\\times 10^{19})$ and $5\\times (2.9\\times 10^{19})$ useful ion decays in neutrino and antineutrino modes respectively, we find that the two-detector set-up can probe maximal CP violation and establish the ne...

    1983-08-01

    There is room for a more balanced view of old age among the ancient Greeks than is furnished by De Beauvoir's la Vieillesse and other more or less one-sided publications. The old body was despised by the Greeks of classical times; especially walking with three legs (tripous) was stressed as a mark of old age. The Hippocratic writings show some interest in the infirmities of elderly people. Specific psychic and intellectual qualities were not attributed to senescence: old age brought out good and bad qualities of a person more sharply than before. The share of old people in the population cannot be established with any certainty, but there was always a group of men in their sixties who had specific tasks in society. Old age was not an autonomous theme in art, it was solely accidental. The position of the elderly was challenged occasionally in democratic Athens, but it was never undermined. Old people were never marginated in classical Greece.

    A four step methodology has been developed for study of the regional impacts of climate change and the possible responses thereto. First the region's climate sensitive sectors and total economy are described (Task A, current baseline). Next a scenario of climate change is imposed on the current baseline (Task B, current baseline with climate change). A new baseline describing the climate sensitive sectors and total regional economy is projected for some time in the future (Task C, future baseline, year 2030) in the absence of climate change. Finally, the climate change scenario is reimposed on the future baseline (Task D, future baseline with climate change). Impacts of the climate change scenario on the current and future regional economies are determined by means of simulation models and other appropriate techniques. These techniques are also used to assess the impacts of an elevated CO[sub 2] concentration (450 ppm) and of various forms of adjustments and adaptations. The region chosen for the first test of the methodology is composed of the four U.S. states of Missouri, Iowa, Nebraska and Kansas. The climate change scenario is the actual weather of the 1930s decade in the MINK region. 'Current' climate is the actual weather of the period 1951-1980. 20 refs., 3 figs., 2 tabs.

    Shifting environmental baselines are inter-generational changes in perception of the state of the environment. As one generation replaces another, people's perceptions of what is natural change even to the extent that they no longer believe historical anecdotes of past abundance or size of species. Although widely accepted, this phenomenon has yet to be quantitatively tested. Here we survey three generations of fishers from Mexico's Gulf of California (N=108), where fish populations have declined steeply over the last 60 years, to investigate how far and fast their environmental baselines are shifting. Compared to young fishers, old fishers named five times as many species and four times as many fishing sites as once being abundant/productive but now depleted (Kruskal–Wallis tests, both p<0.001) with no evidence of a slowdown in rates of loss experienced by younger compared to older generations (Kruskal–Wallis test, n.s. in both cases). Old fishers caught up to 25 times as many Gulf grouper Mycteroperca jordani as young fishers on their best ever fishing day (regression r2=0.62, p<0.001). Despite times of plentiful large fish still being within living memory, few young fishers appreciated that large species had ever been common or nearshore sites productive. Such rapid shifts in perception of what is natural help explain why society is tolerant of the creeping loss of biodiversity. They imply a large educational hurdle in efforts to reset expectations and targets for conservation. PMID:16191603

  18. Trinocular Stereo Matching Based on Correlations Between Baselines and Disparities

    2004-01-01

    Gray correlation technique is utilized to take the multi-peak feature points with gray correlation coefficients less than a certain range of maximal correlation coefficient as a potential candidate matching set. There exists the maximal correlation between the correct disparities and their corresponding baselines. A trinocular stereo matching algorithm is proposed based on correlations between the baselines and disparities. After computing the correlations between the baselines and disparities, the unique matches can be determined by maximal correlation coefficient. It is proved that the algorithm proposed is valid and credible by 3-D reconstruction on two pairs of actual natural stereo images.

    CERN Document Server

    Smirnov, A Yu

    2006-01-01

    Physics interpretation of the ``magic'' baseline that can play important role in future oscillation experiments is given. The ``magic'' baseline coincides with the refraction length, $l_0$. The latter, in turn, approximately equals the oscillation length in matter at high energies. Therefore at the baseline $L = l_0$ the oscillation phase is $2\\pi$, and consequently, the ``solar'' amplitude of oscillations driven by the mixing angle $\\theta_{12}$ and mass splitting $\\Delta m^2_{21}$ vanishes. As a result, in the lowest order (i) the interference of amplitudes in the $\

    This paper proposes a dynamic baseline Traffic detection Method which is based on the historical traffic data for the Power data network. The method uses Cisco's NetFlow acquisition tool to collect the original historical traffic data from network element at fixed intervals. This method uses three dimensions information including the communication port, time, traffic (number of bytes or number of packets) t. By filtering, removing the deviation value, calculating the dynamic baseline value, comparing the actual value with the baseline value, the method can detect whether the current network traffic is abnormal.

    In this contribution, the significance of the salutogenic model (Antonovsky) and its core concept-the sense of coherence-for research into "successful aging" is explicated on the background of a gerodynamic perspective (Schroots). Common to both approaches is the idea that the basic principle of life is based on imbalance, disease, and suffering (heterostasis). According to this pessimistic view, aging is considered as the individual time dimension on which these inevitable impairments in biological, behavioral, and social respects take place. The continuous increase in entropy (disorder) will finally result in the death of the organism. In the face of gerontological research showing variability and individual plasticity in aging processes-especially for the third age-, the salutogenic question is why some people generally become (very) old and stay healthy. According to the salutogenic model, the sense of coherence determines the (re-)production of order over the life span and mediates the relationship between resources/stressors and health outcome. Considering activity/disengagement theory and the selective optimization with compensation model as an example, the integrative potential of the salutogenic model is shown. Finally, the value of the salutogenic model for the fourth age is discussed. Healthy aging is one chance of human existence, but in no way a collective duty that should be imposed on the individual.

  2. New Old Inflation

    Energy Technology Data Exchange (ETDEWEB)

    Dvali, Gia

    2003-10-03

    We propose a new class of inflationary solutions to the standard cosmological problems (horizon, flatness, monopole,...), based on a modification of old inflation. These models do not require a potential which satisfies the normal inflationary slow-roll conditions. Our universe arises from a single tunneling event as the inflaton leaves the false vacuum. Subsequent dynamics (arising from either the oscillations of the inflaton field or thermal effects) keep a second field trapped in a false minimum, resulting in an evanescent period of inflation (with roughly 50 e-foldings) inside the bubble. This easily allows the bubble to grow sufficiently large to contain our present horizon volume. Reheating is accomplished when the inflaton driving the last stage of inflation rolls down to the true vacuum, and adiabatic density perturbations arise from moduli-dependent Yukawa couplings of the inflaton to matter fields. Our scenario has several robust predictions, including virtual absence of gravity waves, a possible absence of tilt in scalar perturbations, and a higher degree of non-Gaussianity than other models. It also naturally incorporates a solution to the cosmological moduli problem.

  3. Too old to work?

    Full Text Available The article reviews Norwegian and international research on aging and work; causes of early exit,attitudes towards older workers, aging and work performance, and trends of changes in working life.Workers seem to have become too old to work at increasingly younger ages. Recent and futuredemographic changes call for initiatives to keep older workers in the work force. In many countriesfavourable early retirement arrangements are reversed in order to stop pulling older workers prematurelyout of work. The other main group of factors causing early exit, the push factors in the work environment,have until recently attracted less attention. Even if older workers in general seem to be no less effectivethan younger workers, employers prefer to recruit younger workers, and to dismiss older workers whenreducing the staff. However, employers’ cognitions of older workes’ performance is quite nuanced. Thereseems to be an emotional ambivalence where negative feelings are less openly expressed, still they seemto have a strong influence on decisions. Ways of influencing attitudes towards older workers arediscussed. Companies creating working conditions to stimulate, include and motivate middle-aged andolder workers may get an advantage in the market. This may even benefit workers of all ages.

    Aging may be associated with an increase in generalized text processing, particularly in adults older than 75 years. The current study examined text comprehension in young, young-old, and old-old adults. Experiment 1 included a comprehension measure (product) and Experiment 2 examined inferences generated during reading (process). Comprehension scores were lowest in old-old adults. Generalized and elaborative inference scores were highest in old-old adults. Participants over 65 years with the lowest scores on cognitive integrity variables also had significantly lower comprehension scores, but there was no effect of cognitive integrity on inference scores. This dissociation suggests that inferential processes may be maintained even when cognitive integrity and comprehension declines are present. Relevance to cognitive aging theories addressing text processing and self-regulatory processes is addressed.

    A. B. W. Tavares

    2013-01-01

    Full Text Available Growth hormone (GH use has been speculated to improve physical capacity in subjects without GH deficiency (GHD through stimulation of collagen synthesis in the tendon and skeletal muscle, which leads to better exercise training and increased muscle strength. In this context, the use of GH in healthy elderly should be an option for increasing muscle strength. Our aim was to evaluate the effect of GH therapy on muscle strength in healthy men over 50 years old. Fourteen healthy men aged 50–70 years were evaluated at baseline for body composition and muscle strength (evaluated by leg press and bench press exercises, which focus primarily on quadriceps—lower body part and pectoralis major—upper body part—muscles, resp.. Subjects were randomised into 2 groups: GH therapy (7 subjects and placebo (7 subjects and reevaluated after 6 months of therapy. Thirteen subjects completed the study (6 subjects in the placebo group and 7 subjects in the GH group. Subjects of both groups were not different at baseline. After 6 months of therapy, muscle strength in the bench press responsive muscles did not increase in both groups and showed a statistically significant increase in the leg press responsive muscles in the GH group. Our study demonstrated an increase in muscle strength in the lower body part after GH therapy in healthy men. This finding must be considered and tested in frail older populations, whose physical incapacity is primarily caused by proximal muscle weakness. The trial was registered with NCT01853566.

  13. Preclinical models for neuroblastoma: establishing a baseline for treatment.

    Directory of Open Access Journals (Sweden)

    Tal Teitz

    Full Text Available BACKGROUND: Preclinical models of pediatric cancers are essential for testing new chemotherapeutic combinations for clinical trials. The most widely used genetic model for preclinical testing of neuroblastoma is the TH-MYCN mouse. This neuroblastoma-prone mouse recapitulates many of the features of human neuroblastoma. Limitations of this model include the low frequency of bone marrow metastasis, the lack of information on whether the gene expression patterns in this system parallels human neuroblastomas, the relatively slow rate of tumor formation and variability in tumor penetrance on different genetic backgrounds. As an alternative, preclinical studies are frequently performed using human cell lines xenografted into immunocompromised mice, either as flank implant or orthtotopically. Drawbacks of this system include the use of cell lines that have been in culture for years, the inappropriate microenvironment of the flank or difficult, time consuming surgery for orthotopic transplants and the absence of an intact immune system. PRINCIPAL FINDINGS: Here we characterize and optimize both systems to increase their utility for preclinical studies. We show that TH-MYCN mice develop tumors in the paraspinal ganglia, but not in the adrenal, with cellular and gene expression patterns similar to human NB. In addition, we present a new ultrasound guided, minimally invasive orthotopic xenograft method. This injection technique is rapid, provides accurate targeting of the injected cells and leads to efficient engraftment. We also demonstrate that tumors can be detected, monitored and quantified prior to visualization using ultrasound, MRI and bioluminescence. Finally we develop and test a "standard of care" chemotherapy regimen. This protocol, which is based on current treatments for neuroblastoma, provides a baseline for comparison of new therapeutic agents. SIGNIFICANCE: The studies suggest that use of both the TH-NMYC model of neuroblastoma and the

    Many women in Cape Verde are actively working to upgrade the status of women in the country and are playing a major role in development programs. The small country of Cape Verde, 455 kilometers off the coast of Senegal, obtained its independence from Portugal in 1975. Even before independence many women were politically conscious and women's rights were a part of the program of Cape Verde's liberation movement. In 1978 the National Women's Organization was formed. The organization places a high priority on education for women and is promoting a large scale literacy campaign. During the colonial period most of Cape Verde's land was destroyed and the country's economy was ruined. A large proportion of the Cape Verde's male population emigrates to other countries in order to obtain work, and the women are left behind to raise their large families on their own. There is a great need to intensify efforts to restore the land's fertility and to control erosion. The country also needs schools, clinics, and transportation and communication networks. Many women are involved in a large water and conservation program supported by Oxfam and other international agencies. Women are encouraged to work on construction jobs, drive trucks and build dikes. Old attitudes are hard to change, however, and there is a need to involve a larger segment of the female population in the women's rights movement. In December, 1980 the Women's Organization will hold its 1st National Conference. The organization will map its future strategies for upgrading the position of women in Cape Verde society and for increasing support for the women's movements.

  5. Lags and leads in life satisfaction: a test of the baseline hypothesis

    We look for evidence of habituation in twenty waves of German panel data: do individuals, after life and labour market events, tend to return to some baseline level of wellbeing? Although the strongest life satisfaction effect is often at the time of the event, we find significant lag and lead effects. We conclude that there is complete adaptation to divorce, widowhood, birth of first child, and layoff. However, adaptation to marriage is only incomplete, and there is no adaptation to unemploy...

    The past research of the radiologic manifestations of pulmonary tuberculosis in Japan was based on morphological pathology of the untreated patient autopsy. I would like to show the chest CT scan of tuberculosis diseases with caseous granuloma at its exudative reaction, proliferative reaction, productive reaction, cirrhotic reaction until self cure. This progress reflects the normal cell mediated immunological responses. Also I would like to show the cavitation of granuloma, which results from liquefaction of caseous materials during the course and results in the formation of the source of infection. And finally I would like to show the morphological differences of acinous lesion, acino-nodular lesion and caseous lobular pneumonia. These differences reflect the amount of bacilli disseminated in the peripheral parts under the lobules. In this study, I do not show old age cases and HIV positive cases, who do not form typical granuloma due to the decreased cell mediated immnunity and whose X ray findings are atypical.

    Full Text Available One of the greatest difficulties in stereo vision is the appearance of ambiguities when matching similar points from different images. In this article we analyze the effectiveness of using a fusion of multiple baselines and a range finder from a theoretical point of view, focusing on the results of using both prismatic and rotational articulations for baseline generation, and offer a practical case to prove its efficiency on an autonomous vehicle.

    A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavelengths requires baselines up to ∼15 km. To develop and test this capability, a Long Baseline Campaign (LBC) was carried out from 2014 September to late November, culminating in end-to-end observations, calibrations, and imaging of selected Science Verification (SV) targets. This paper presents an overview of the campaign and its main results, including an investigation of the short-term coherence properties and systematic phase errors over the long baselines at the ALMA site, a summary of the SV targets and observations, and recommendations for science observing strategies at long baselines. Deep ALMA images of the quasar 3C 138 at 97 and 241 GHz are also compared to VLA 43 GHz results, demonstrating an agreement at a level of a few percent. As a result of the extensive program of LBC testing, the highly successful SV imaging at long baselines achieved angular resolutions as fine as 19 mas at ∼350 GHz. Observing with ALMA on baselines of up to 15 km is now possible, and opens up new parameter space for submm astronomy.

  9. MALDI-TOF Baseline Drift Removal Using Stochastic Bernstein Approximation

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Stochastic Bernstein (SB approximation can tackle the problem of baseline drift correction of instrumentation data. This is demonstrated for spectral data: matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF data. Two SB schemes for removing the baseline drift are presented: iterative and direct. Following an explanation of the origin of the MALDI-TOF baseline drift that sheds light on the inherent difficulty of its removal by chemical means, SB baseline drift removal is illustrated for both proteomics and genomics MALDI-TOF data sets. SB is an elegant signal processing method to obtain a numerically straightforward baseline shift removal method as it includes a free parameter that can be optimized for different baseline drift removal applications. Therefore, research that determines putative biomarkers from the spectral data might benefit from a sensitivity analysis to the underlying spectral measurement that is made possible by varying the SB free parameter. This can be manually tuned (for constant or tuned with evolutionary computation (for .

    Full Text Available Abstract Background Findings from several studies suggest associations between tooth loss and health outcomes, including malnutrition, poor quality of life, and mortality, in older individuals. However, limited information is available regarding whether those associations remain true in very elderly subjects after adequately considering confounding factors such as sex and smoking status. Herein, we determined whether the number of teeth in 80-year-old subjects is an independent predictor of mortality. Methods We initially contacted 1282 80-year-old community-dwelling individuals born in 1917, of whom 697 responded and participated in a baseline study, with follow-up examinations conducted 4 and 5.5 years later. Data from interviews and medical and oral examinations were obtained, and oral health was determined according to the number of teeth remaining in the oral cavity. Results A total of 108 and 157 subjects died in 4 years and 5.5 years, respectively, after the baseline study. Tooth loss was significantly associated with mortality at age 85.5, but not at age 84, after adjusting for potential confounders. When the analysis was stratified by sex, we found a stronger association in females in follow-up examinations conducted at both 4- and 5.5 years. On the other hand, the effect of tooth loss on mortality was not significantly different between smokers and non-smokers. Conclusion Tooth loss is a significant predictor of mortality independent of health factors, socio-economic status, and lifestyle in octogenarians, with a stronger association in females.

  12. Precise baseline determination for the TanDEM-X mission

    Koenig, Rolf; Moon, Yongjin; Neumayer, Hans; Wermuth, Martin; Montenbruck, Oliver; Jäggi, Adrian

    The TanDEM-X mission will strive for generating a global precise Digital Elevation Model (DEM) by way of bi-static SAR in a close formation of the TerraSAR-X satellite, already launched on June 15, 2007, and the TanDEM-X satellite to be launched in May 2010. Both satellites carry the Tracking, Occultation and Ranging (TOR) payload supplied by the GFZ German Research Centre for Geosciences. The TOR consists of a high-precision dual-frequency GPS receiver, called Integrated GPS Occultation Receiver (IGOR), and a Laser retro-reflector (LRR) for precise orbit determination (POD) and atmospheric sounding. The IGOR is of vital importance for the TanDEM-X mission objectives as the millimeter level determination of the baseline or distance between the two spacecrafts is needed to derive meter level accurate DEMs. Within the TanDEM-X ground segment GFZ is responsible for the operational provision of precise baselines. For this GFZ uses two software chains, first its Earth Parameter and Orbit System (EPOS) software and second the BERNESE software, for backup purposes and quality control. In a concerted effort also the German Aerospace Center (DLR) generates precise baselines independently with a dedicated Kalman filter approach realized in its FRNS software. By the example of GRACE the generation of baselines with millimeter accuracy from on-board GPS data can be validated directly by way of comparing them to the intersatellite K-band range measurements. The K-band ranges are accurate down to the micrometer-level and therefore may be considered as truth. Both TanDEM-X baseline providers are able to generate GRACE baselines with sub-millimeter accuracy. By merging the independent baselines by GFZ and DLR, the accuracy can even be increased. The K-band validation however covers solely the along-track component as the K-band data measure just the distance between the two GRACE satellites. In addition they inhibit an un-known bias which must be modelled in the comparison, so the

    Two cases of osteogenesis imperfecta found in one family (father and daughter) are reported, and the CT findings are described. Case 1 is a 58-year-old man who fell and struck his head at home on November 10, 1984. He was transferred to Omuta City Hospital when he became semicomatose and decerebrate posturing was noted. His family history revealed 8 persons with osteogenesis imperfecta. A skull X-ray film showed a large skull vault, many wormian bones at the lambdoid suture, platybasia, and a basilar impression. A CT scan demonstrated a right acute subdural hematoma, while the bone image showed well-developed mastoid air cells and a skull deformity characteristic of osteogenesis imperfecta. He had an emergency operation, and a 170-gr clot was successfully evacuated. A postoperative CT scan demonstrated brain atrophy, possibly present before head trauma. Case 2 is the daughter of Case 1 (a 27-year-old woman). She also showed characteristic neuroradiological manifestations on a plain skull film and on a CT scan. A basilar impression and platybasia were also demonstrated. In this report, the possible mechanism of the production of a traumatic acute subdural hematoma is also discussed.

    Animal studies have shown that glutamine supplementation may decrease colon carcinogenesis, but any relation with glutamine or its precursors has not been studied in humans. The primary aim of this study was to assess whether dietary glutamic acid intake was associated with colorectal cancer (CRC) risk in community-dwelling adults. A secondary aim was to evaluate whether the association could be modified by the body mass index (BMI). This study was embedded in the Rotterdam study, which included a prospective cohort from 1990 onward that consisted of 5362 subjects who were 55 years old or older and were free of CRC at the baseline. Glutamic acid was calculated as a percentage of the total protein intake with a validated food frequency questionnaire at the baseline. Incident cases of CRC were pathology-based. During follow-up, 242 subjects developed CRC. Baseline dietary glutamic acid intake was significantly associated with a lower risk of developing CRC (hazard ratio [HR] per percent increase in glutamic acid of protein, 0.78; 95% confidence interval [CI], 0.62-0.99). After stratification for BMI, the risk reduction for CRC by dietary glutamic acid was 42% for participants with a BMI ≤ 25 kg/m(2) (HR per percent increase in glutamic acid of protein, 0.58; 95% CI, 0.40-0.85), whereas no association was found in participants with a BMI > 25 kg/m(2) (HR per percent increase in glutamic acid of protein, 0.97; 95% CI, 0.73-1.31). Our data suggest that baseline dietary glutamic acid intake is associated with a lower risk of developing CRC, but this association may be mainly present in nonoverweight subjects. © 2015 American Cancer Society.

    2003-06-01

    Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

    Full Text Available Wernicke encephalopathy (WE is an acute neuropsychiatric syndrome resulting from thiamine (vitamin B1 deficiency, classically characterized by the triad of ophthalmoplegia, confusion, and ataxia. While commonly associated with chronic alcoholism, WE may also occur in the setting of poor nutrition or absorption. We present a 37-year-old woman who underwent laparoscopic sleeve gastrectomy and presented with visual disturbance with bilateral horizontal nystagmus, confusion, and postural imbalance. Fundus examination revealed bilateral optic disc edema with a retinal hemorrhage in the left eye. Metabolic workup demonstrated thiamine deficiency. Her symptoms resolved after thiamine treatment. This case raises the awareness of the possibility of posterior segment findings in WE, which are underreported in WE.

  17. Baseline CSF p-tau levels independently predict progression of hippocampal atrophy in Alzheimer disease

    Objective: To investigate whether baseline CSF biomarkers are associated with hippocampal atrophy rate as a measure of disease progression in patients with Alzheimer disease (AD), patients with mild cognitive impairment (MCI), and controls, controlling for baseline neuropsychological and MRI findings. Methods: We assessed data from 31 patients with AD, 25 patients with MCI, and 19 controls (mean age 68 ± 8 years; 39 [52%] female) who visited our memory clinic and had received serial MRI scanning (scan interval 1.7 ± 0.7 years). At baseline, CSF biomarkers (amyloid β 1-42, tau, and tau phosphorylated at threonine 181 [p-tau]) were obtained, as well as neuropsychological data. Baseline MRI scans were assessed using visual rating scales for medial temporal lobe atrophy (MTA), global cortical atrophy, and white matter hyperintensities. Hippocampal atrophy rates were estimated using regional nonlinear “fluid” registration of follow-up scan to baseline scan. Results: Stepwise multiple linear regression, adjusted for age and sex, showed that increased CSF p-tau levels (β [standard error]: −0.79 [0.35]) at baseline was independently associated with higher subsequent hippocampal atrophy rates (p < 0.05), together with poorer memory performance (0.09 [0.04]) and more severe MTA (−0.60 [0.21]). The association of memory function with hippocampal atrophy rate was explained by the link with diagnosis, because it disappeared from the model after we additionally corrected for diagnosis. Conclusions: Baseline CSF levels of tau phosphorylated at threonine 181 are independently associated with subsequent disease progression, as reflected by hippocampal atrophy rate. This effect is independent of baseline neuropsychological and MRI predictors. Our results imply that predicting disease progression can best be achieved by combining information from different modalities.

  18. Optimal core baseline design and observing strategy for probing the astrophysics of reionization with the SKA

    Greig, Bradley; Koopmans, Léon V E

    2015-01-01

    With the first phase of the Square Kilometre Array (SKA1) entering into its final pre-construction phase, we investigate how best to maximise its scientific return. Specifically, we focus on the statistical measurement of the 21 cm power spectrum (PS) from the epoch of reionization (EoR) using the low frequency array, SKA1-low. To facilitate this investigation we use the recently developed MCMC based EoR analysis tool 21CMMC (Greig & Mesinger). In light of the recent 50 per cent cost reduction, we consider several different SKA core baseline designs, changing: (i) the number of antenna stations; (ii) the number of dipoles per station; and also (iii) the distribution of baseline lengths. We find that a design with a reduced number of dipoles per core station (increased field of view and total number of core stations), together with shortened baselines, maximises the recovered EoR signal. With this optimal baseline design, we investigate three observing strategies, analysing the trade-off between lowering t...

  19. Effects of baseline reinforcement rate on operant ABA and ABC renewal.

    Science.gov (United States)

    Berry, Meredith S; Sweeney, Mary M; Odum, Amy L

    2014-10-01

    Renewal is a relapse phenomenon that occurs when the contextual stimuli present during extinction change, and consequently, an extinguished response increases in rate. Two experiments assessed extinction and renewal of key-pecking in pigeons in a two-component multiple schedule wherein baseline reinforcer rates were delivered at relatively rich or lean rates. In Experiment 1, an ABA design was used in which baseline stimuli were steady key lights (Context A). Food was then removed during extinction, and simultaneously, the context was changed by flashing the key lights (Context B). Following extinction, steady key lights were reintroduced, but food remained unavailable. Key-pecking was more resistant to extinction and recovered to a greater degree in the rich relative to the lean component. In Experiment 2, we introduced novel stimuli following extinction (ABC renewal) rather than reintroducing baseline stimuli. Similar to Experiment 1, in Experiment 2 resistance to change and renewal remained greater in the component associated with higher reinforcer rates during baseline. These findings provide additional support for the context-specificity of operant extinction, and support the prediction of behavioral momentum theory that stimuli associated with higher rates of reinforcement engender greater persistence and relapse than those associated with lower rates of reinforcement.

  20. National greenhouse gas emissions baseline scenarios. Learning from experiences in developing countries

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2013-04-15

    This report reviews national approaches to preparing baseline scenarios of greenhouse-gas (GHG) emissions. It does so by describing and comparing in non-technical language existing practices and choices made by ten developing countries - Brazil, China, Ethiopia, India, Indonesia, Kenya, Mexico, South Africa, Thailand and Vietnam. The review focuses on a number of key elements, including model choices, transparency considerations, choices about underlying assumptions and challenges associated with data management. The aim is to improve overall understanding of baseline scenarios and facilitate their use for policy-making in developing countries more broadly. The findings are based on the results of a collaborative project involving a number of activities undertaken by the Danish Energy Agency, the Organisation for Economic Co-operation and Development (OECD) and the UNEP Risoe Centre (URC), including a series of workshops on the subject. The ten contributing countries account for approximately 40% of current global GHG emissions - a share that is expected to increase in the future. The breakdown of emissions by sector varies widely among these countries. In some countries, the energy sector is the leading source of emissions; for others, the land-use sector and/or agricultural sector dominate emissions. The report underscores some common technical and financial capacity gaps faced by developing countries when preparing baseline scenarios. It does not endeavour to propose guidelines for preparing baseline scenarios. Rather, it is hoped that the report will inform any future attempts at preparing such kind of guidelines. (Author)

  1. Age and Abundance Discrimination in Old Stellar Populations Using Mid-Ultraviolet Colors

    Dorman, B; Rood, R T; Dorman, Ben; Connell, Robert W. O'; Rood, Robert T.

    2003-01-01

    The restframe mid-ultraviolet spectral region (2000-3200 A) is important in analyzing the stellar populations of the "red envelope" systems observed at high redshifts. Here, we explore the usefulness of the mid-UV for determining ages and abundances of old populations. A mid-UV to optical/IR wavelength baseline provides good separation of population components because the main sequence turnoff dominates the integrated light between 2500 and 4000 A. We find a six magnitude difference in the mid-UV continuum level over the metallicity range -1.5 < log Z/Z_o < +0.5 and a comparable difference (per unit log t) for ages in the range 4-16 Gyr. Logarithmic derivatives of mid-UV colors with respect to age or metal abundance are 3-10 times larger than for the UBV region. Most of the spectral information on old populations therefore resides below 4000 A. We investigate the capability of UBV and mid-UV broad-band colors to separately determine age and abundance, taking into account precision in the color measureme...

    2012-12-15

    The purpose of this study was to report the MRI findings that can be encountered in successfully treated bacterial septic arthritis. The study included 12 patients (8 male and 4 female; mean age 38 years, range 9-85) with 13 proven cases of bacterial septic arthritis. The joints involved were hip (n = 3), knee (n = 3), shoulder (n = 2), sacroiliac (n = 2), ankle (n = 1), wrist (n = 1), and elbow (n = 1). MRI examinations following surgical debridement and at initiation of antibiotic therapy and after successful treatment were compared for changes in effusion, synovium, bone, and periarticular soft tissues. Imaging findings were correlated with microbiological and clinical findings. Joint effusions were present in all joints at baseline and regressed significantly at follow-up MRI (p = 0.001). Abscesses were present in 5 cases (38 %), and their sizes decreased significantly at follow-up (p = 0.001). Synovial enhancement and thickening were observed in all joints at both baseline and follow-up MRI. Myositis/cellulitis was present in 10 cases (77 %) at baseline and in 8 cases (62 %) at follow-up MRI. Bone marrow edema was present in 10 joints (77 %) at baseline and persisted in 8 joints (62 %). Bone erosions were found in 8 joints (62 %) and persisted at follow-up MRI in all cases. The sizes of joint effusions and abscesses appear to be the factors with the most potential for monitoring therapy for septic arthritis, since both decreased significantly following successful treatment. Synovial thickening and enhancement, periarticular myositis/cellulitis, and bone marrow edema can persist even after resolution of the infection. (orig.)

  4. Way to increase the user access at the LCLS baseline

    Geloni, Gianluca; Saldin, Evgeni

    2010-01-01

    The LCLS beam is meant for a single user, but the baseline undulator is long enough to serve two users simultaneously. To this end, we propose a setup composed of two elements: an X-ray mirrors pair for X-ray beam deflection, and a 4 m-long magnetic chicane, which creates an offset for mirrors pair installation in the middle of the baseline undulator. The insertable mirrors pair can separate spatially the X-ray beams generated in the first and in the second half of the baseline undulator. Rapid switching of the FEL amplification process allows deactivating one half and activating another half of the undulator. As proposed elsewhere, using a kicker installed upstream of the LCLS baseline undulator and an already existing corrector in the first half of the undulator, it is possible to rapidly switch the X-ray beam from one user to another. We present simulation results for the LCLS baseline, and show that it is possible to generate two saturated SASE X-ray beams in the whole 0.8-8 keV photon energy range in the...

  5. Deformation Monitoring of the Submillimetric UPV Calibration Baseline

    García-Asenjo, Luis; Baselga, Sergio; Garrigues, Pascual

    2017-06-01

    A 330 m calibration baseline was established at the Universitat Politècnica de València (UPV) in 2007. Absolute scale was subsequently transferred in 2012 from the Nummela Standard Baseline in Finland and distances between pillars were determined with uncertainties ranging from 0.1 mm to 0.3 mm. In order to assess the long-term stability of the baseline three field campaigns were carried out from 2013 to 2015 in a co-operative effort with the Universidad Complutense de Madrid (UCM), which provided the only Mekometer ME5000 distance meter available in Spain. Since the application of the ISO17123-4 full procedure did not suffice to come to a definite conclusion about possible displacements of the pillars, we opted for the traditional geodetic network approach. This approach had to be adapted to the case at hand in order to deal with problems such as the geometric weakness inherent to calibration baselines and scale uncertainty derived from both the use of different instruments and the high correlation between the meteorological correction and scale determination. Additionally, the so-called the maximum number of stable points method was also tested. In this contribution it is described the process followed to assess the stability of the UPV submillimetric calibration baseline during the period of time from 2012 to 2015.

  6. Combined GPS + BDS for short to long baseline RTK positioning

    2015-04-01

    The BeiDou Navigation Satellite System (BDS) has become fully operational in the Asia-Pacific region and it is of importance to evaluate what BDS brings when combined with the Global Positioning System (GPS). In this contribution we will look at the short, medium and long single-baseline real-time kinematic (RTK) positioning performance. Short baseline refers to when the distance between the two receivers is at most a few kilometers so that the relative slant ionospheric and tropospheric delays can be assumed absent, whereas with medium baseline we refer to when the uncertainty of these ionospheric delays can reliably be modeled as a function of the baseline length. With long baseline we refer to the necessity to parameterize the ionospheric delays and (wet) Zenith Tropospheric Delay (ZTD) as completely unknown. The GNSS real data are collected in Perth, Australia. It will be shown that combining the two systems allows for the use of higher than customary elevation cut-off angles. This can be of particular benefit in environments with restricted satellite visibility such as in open pit mines or urban canyons.

    Calculating greenhouse gas emissions reductions from climate change mitigation projects requires construction of a baseline that sets emissions levels that would have occurred without the project. This paper describes a standardized multiproject methodology for setting baselines, represented by the emissions rate (kg C/kWh), for electric power projects. A standardized methodology would reduce the transaction costs of projects. The most challenging aspect of setting multiproject emissions rates is determining the vintage and types of plants to include in the baseline and the stringency of the emissions rates to be considered, in order to balance the desire to encourage no- or low-carbon projects while maintaining environmental integrity. The criteria for selecting power plants to include in the baseline depend on characteristics of both the project and the electricity grid it serves. Two case studies illustrate the application of these concepts to the electric power grids in eastern India and South Africa. We use hypothetical, but realistic, climate change projects in each country to illustrate the use of the multiproject methodology, and note the further research required to fully understand the implications of the various choices in constructing and using these baselines.

    Atmospheric mass loading produces a primarily vertical displacement of the Earth's crust. This displacement is correlated with surface pressure and is large enough to be detected by very long baseline interferometry (VLBI) measurements. Using the measured surface pressure at VLBI stations, we have estimated the atmospheric loading term for each station location directly from VLBI data acquired from 1979 to 1992. Our estimates of the vertical sensitivity to change in pressure range from 0 to -0.6 mm/mbar depending on the station. These estimates agree with inverted barometer model calculations (Manabe et al., 1991; vanDam and Herring, 1994) of the vertical displacement sensitivity computed by convolving actual pressure distributions with loading Green's functions. The pressure sensitivity tends to be smaller for stations near the coast, which is consistent with the inverted barometer hypothesis. Applying this estimated pressure loading correction in standard VLBI geodetic analysis improves the repeatability of estimated lengths of 25 out of 37 baselines that were measured at least 50 times. In a root-sum-square (rss) sense, the improvement generally increases with baseline length at a rate of about 0.3 to 0.6 ppb depending on whether the baseline stations are close to the coast. For the 5998-km baseline from Westford, Massachusetts, to Wettzell, Germany, the rss improvement is about 3.6 mm out of 11.0 mm. The average rss reduction of the vertical scatter for inland stations ranges from 2.7 to 5.4 mm.

    This document describes procedures for testing and validating proprietary baseline energy modeling software accuracy in predicting energy use over the period of interest, such as a month or a year. The procedures are designed according to the methodology used for public domain baselining software in another LBNL report that was (like the present report) prepared for Pacific Gas and Electric Company: ?Commercial Building Energy Baseline Modeling Software: Performance Metrics and Method Testing with Open Source Models and Implications for Proprietary Software Testing Protocols? (referred to here as the ?Model Analysis Report?). The test procedure focuses on the quality of the software?s predictions rather than on the specific algorithms used to predict energy use. In this way the software vendor is not required to divulge or share proprietary information about how their software works, while enabling stakeholders to assess its performance.

    Optical long baseline interferometry is a technique that has generated almost 850 refereed papers to date. The targets span a large variety of objects from planetary systems to extragalactic studies and all branches of stellar physics. We have created a database hosted by the JMMC and connected to the Optical Long Baseline Interferometry Newsletter (OLBIN) web site using MySQL and a collection of XML or PHP scripts in order to store and classify these publications. Each entry is defined by its ADS bibcode, includes basic ADS informations and metadata. The metadata are specified by tags sorted in categories: interferometric facilities, instrumentation, wavelength of operation, spectral resolution, type of measurement, target type, and paper category, for example. The whole OLBIN publication list has been processed and we present how the database is organized and can be accessed. We use this tool to generate statistical plots of interest for the community in optical long baseline interferometry.

    Sawfishes (Pristidae) were formerly abundant in the western Indian Ocean, but current data on sawfish presence and distribution are lacking for most of the region. This paper summarises historical records of sawfishes in Mozambican waters and presents the findings of the first assessment of the presence and status of sawfishes in Mozambique. A countrywide baseline assessment was undertaken between May and July 2014, using interviews with artisanal, semi-industrial and industrial fishers, fish traders and fisheries monitoring staff as the primary source of information on sawfish distribution, recent catches, socio-economic value and cultural importance. Additional interviews were conducted via email or telephone with individuals running sport fishing operations or who otherwise had considerable experience interacting with the fishing sectors or the marine environment in Mozambique. Where encountered, sawfish rostra were photographed and a series of measurements and associated data were collected. In total, 200 questionnaire surveys and seven interviews with recreational fishing and dive operators were conducted, and 19 rostra were documented from museum archives and private collections, belonging to two sawfish species, the Largetooth Sawfish (Pristis pristis) and Green Sawfish (P. zijsron). The most recent captures of sawfishes were reported to have occurred in 2014. Two key sites were identified where both recent encounters were reported and numerous Largetooth Sawfish rostra were documented. Gill nets were the fishing gear most commonly attributed to sawfish catches. Sawfishes did not hold any cultural importance in Mozambique, but they have at least some socio-economic importance to artisanal fishers, primarily through the sale of their fins. The meat did not appear to be held in high regard and was usually consumed locally. Sampling and further research is now required to confirm the presence of sawfishes and to assess the primary threats to sawfishes in those

    Growing interest in collaborative goal-setting has raised questions. First, are patients making the 'right choices' from a biomedical perspective? Second, are patients and providers setting goals of appropriate difficulty? Finally, what types of support will patients need to accomplish their goals? We analyzed goals and action plans from a trial of collaborative goal-setting among 302 residents of a high-poverty urban region who had multiple chronic conditions. Patients used a low-literacy aid to prioritize one of their chronic conditions and then set a goal for that condition with their primary care provider. Patients created patient-driven action plans for reaching these goals. Patients chose to focus on conditions that were in poor control and set ambitious chronic disease management goals. The mean goal weight loss -16.8lbs (SD 19.5), goal HbA1C reduction was -1.3% (SD 1.7%) and goal blood pressure reduction was -9.8mmHg (SD 19.2mmHg). Patient-driven action plans spanned domains including health behavior (58.9%) and psychosocial (23.5%). High-risk, low-SES patients identified high priority conditions, set ambitious goals and generate individualized action plans for chronic disease management. Practices may require flexible personnel who can support patients using a blend of coaching, social support and navigation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Background Atherosclerotic cardiovascular disease is highly prevalent in Eastern and Central Europe, where the incidence is the highest in the world. The Kardiovize Brno 2030 study was designed as a prospective cohort study to investigate the complex relationships of cardiovascular disease and outcomes with a range of biological, psychosocial, environmental, behavioral, and economic factors in an urban population of the Czech Republic. Methods We randomly selected a 1% sample of the city of Brno residents aged 25-64 years stratified by sex and age. The study assessed traditional and novel cardiovascular disease risk factors, including sociodemographic and smoking status, physical activity, diet, depression, stress, body fat, cardio-ankle vascular index, and intima media thickness, complemented by blood tests; biological samples were stored for future analyses. Results The study enrolled 2160 participants (54.8% women), with a mean age of 47 ± 11.3 years. They were mostly full-time employed (75.6%) and married (62.1%). Hyperlipidemia was highly prevalent (70.7% in men, and 67.1% in women, NS). Hypertension and diabetes mellitus were more prevalent in men than in women (54.3% vs. 38.7% and 7.1% vs. 3.5%, respectively, P 2030 study will provide unique multidimensional and longitudinal cardiovascular health data from a region where epidemiological studies are scarce.

    This pilot study aims to assess Escherichia coli (E. coli) contamination and its perceived health risks among beachgoers in ten tropical beach sands along Port Dickson coastline (Malaysia). This study also aims to determine the relationship between perceived health symptoms and tropical beach sand exposure behavior. The concentration of E. coli in tropical beach sand ranged from 60cfu/100g to 4113cfu/100g. E. coli contamination was the highest at Tanjung Gemuk (4113±30cfu/100g) and the lowest at Tanjung Tuan (60±15cfu/100g); the high level of contamination could be due to the location of the former at the sewage outlet of nearby hotels. Skin symptoms were the most predominant among the health symptoms indicated by beachgoers. Exposure duration was significantly correlated with the perceived health symptoms among beachgoers in the beaches studied.

    Objective The objective of this study was to describe the incidence of baseline change within normal range during labor and its prediction of neonatal outcomes. Materials and Methods This was a prospective cohort of singleton, nonanomalous, term neonates with continuous electronic fetal monitoring and normal baseline fetal heart rate throughout the last 2 hours of labor. We determined baseline in 10-minute segments using Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria. We evaluated baseline changes of ≥ 20 and ≥ 30 bpm for association with acidemia (umbilical cord arterial pH ≤ 7.10) and neonatal intensive care unit (NICU) admission. Finally, we performed a sensitivity analysis of normal neonates, excluding those with acidemia, NICU admission, or 5-minute Apgar bpm; 272 (9.0%) had ≥ 30 bpm. Among normal neonates (n = 2,939), 1,221 (41.5%) had change ≥20 bpm. Acidemia was not associated with baseline change of any direction or magnitude. NICU admission was associated with decrease ≥ 20 bpm (adjusted odds ratio [aOR]: 2.93; 95% confidence interval [CI]: 1.19 - 7.21) or any direction ≥ 20 bpm (aOR: 4.06; 95% CI: 1.46-11.29). For decrease ≥ 20 bpm, sensitivity and specificity were 40.0 and 81.7%; for any direction ≥ 20 bpm, 75.0 and 58.3%. Conclusion Changes of normal baseline are common in term labor and poorly predict morbidity, regardless of direction or magnitude.

    Full Text Available Urachal carcinoma is a rare neoplasm, which accounts for only 0.5–2% of bladder malignancies, and arises from a remnant of the fetal genitourinary tract. A 46-year-old woman presented with a history of pelvic pain and frequent daytime urination. Ultrasound (US, computed tomography (CT, and magnetic resonance (MR demonstrated a supravesical heterogeneous mass with calcifications. The patient underwent a partial cystectomy with en-bloc resection of the mass and histopathological examination revealed the diagnosis of urachal adenocarcinoma. Urachal carcinomas are usually associated with poor prognosis and early diagnosis is fundamental. CT and MR are useful to correctly diagnose and preoperatively staging.

    Full Text Available Abstract Background To compare two approaches to the statistical analysis of the relationship between the baseline incidence of adverse events and the effect of medical emergency teams (METs. Methods Using data from a cluster randomized controlled trial (the MERIT study, we analysed the relationship between the baseline incidence of adverse events and its change from baseline to the MET activation phase using quadratic modelling techniques. We compared the findings with those obtained with conventional subgroup analysis. Results Using linear and quadratic modelling techniques, we found that each unit increase in the baseline incidence of adverse events in MET hospitals was associated with a 0.59 unit subsequent reduction in adverse events (95%CI: 0.33 to 0.86 after MET implementation and activation. This applied to cardiac arrests (0.74; 95%CI: 0.52 to 0.95, unplanned ICU admissions (0.56; 95%CI: 0.26 to 0.85 and unexpected deaths (0.68; 95%CI: 0.45 to 0.90. Control hospitals showed a similar reduction only for cardiac arrests (0.95; 95%CI: 0.56 to 1.32. Comparison using conventional subgroup analysis, on the other hand, detected no significant difference between MET and control hospitals. Conclusions Our study showed that, in the MERIT study, when there was dependence of treatment effect on baseline performance, an approach based on regression modelling helped illustrate the nature and magnitude of such dependence while sub-group analysis did not. The ability to assess the nature and magnitude of such dependence may have policy implications. Regression technique may thus prove useful in analysing data when there is a conditional treatment effect.

    In this paper, we discuss a possibility of studying properties of dark energy in long baseline neutrino oscillation experiments. We consider two types of models of neutrino dark energy. For one type of models the scalar field is taken to be quintessence-like and for the other phantom-like. In these models the scalar fields couple to the neutrinos to give rise to spatially varying neutrino masses. We will show that the two types of models predict different behaviors of the spatial variation of the neutrino masses inside the Earth and consequently result in different signals in long baseline neutrino oscillation experiments.

    2015-07-15

    Accelerator based long-baseline neutrino oscillation experiments have been playing important roles in revealing the nature of neutrinos. However, it turned out that the current experiments are not sufficient to study two major remaining problems, the CP violation in the lepton sector and the mass hierarchy of neutrinos. Therefore, several new experiments have been proposed. Among of them, two accelerator based long-baseline neutrino oscillation experiments, the J-PARC neutrino beam and Hyper-Kamiokande, and MOMENT, have been proposed in Asia. These two projects are reviewed in this article.

    The paper presents the conceptual technical baseline design of a solar electric power plant using the central receiver concept, and derives credible cost estimates from the baseline design. The major components of the plant - heliostats, tower, receiver, tower piping, and thermal storage - are discussed in terms of technical and cost information. The assumed peak plant output is 215 MW(e), over 4000 daylight hours. The contribution of total capital investment to energy cost is estimated to be about 55 mills per kwh in mid-1974 dollars.

    Three-neutrino mixing schemes suggested by Cardall \\& Fuller and Acker \\& Pakvasa are compared and contrasted. Both of these schemes seek to solve the solar and atmospheric neutrino problems {\\em and} to account for the possible neutrino oscillation signal in the LSND experiment. These neutrino oscillation schemes have different atmospheric and solar neutrino signatures that will be discriminated by Super-Kamiokande and SNO. They will also have different signatures in proposed long-baseline accelerator and reactor experiments. In particular, both of these schemes would give dramatic (and dramatically different) signals in an ``intermediate baseline'' experiment, such as the proposed ICARUS detector in the Jura mountains 17 km from CERN.

    The drifting baselines of capillary electrophoresis affect the veracity of analysis greatly. This paper presents Threshold Fitting Technique(TFT) so as to subtract the baselines from the original signals and emendate the signals. In TFT, wav elet and curve fitting technique are applied synthetically, thresholds are decided by the computer automatically. Many experiments of signal processing indicate that TFT is simple for being used, there are few man-induced factors, and the results are satisfactory. TFT can be applied for noisy signals without any pre-processing.

    The change of the equivalent baseline and interferometric phase of cluster SAR satellites is analyzed when the constellation circles around the Earth and the satellites rotate around the center at the same time. The letter provides assessment of baseline error and phase error which influence the precision of height measurement in the across-track interferometric mode. The mathematical model of cluster satellite movement is built, simulation analyses and the curve of height error are presented. The simulation results show that height measurement error can be compensated by the formulae derived in this letter, therefore, the Digital Elevation Models (DEM's) are recovered accurately.

    We examine the reach of a Beta-beam experiment with two detectors at carefully chosen baselines for exploring neutrino mass parameters. Locating the source at CERN, the two detectors and baselines are: (a) a 50 kton iron calorimeter (ICAL) at a baseline of around 7150 km which is roughly the magic baseline, e.g., ICAL-INO, and (b) a 50 kton Totally Active Scintillator Detector at a distance of 730 km, e.g., at Gran Sasso. We choose {sup 8}B and {sup 8}Li source ions with a boost factor {gamma} of 650 for the magic baseline while for the closer detector we consider {sup 18}Ne and {sup 6}He ions with a range of Lorentz boosts. We find that the locations of the two detectors complement each other leading to an exceptional high sensitivity. With {gamma}=650 for {sup 8}B/{sup 8}Li and {gamma}=575 for {sup 18}Ne/{sup 6}He and total luminosity corresponding to 5x(1.1x10{sup 18}) and 5x(2.9x10{sup 18}) useful ion decays in neutrino and antineutrino modes respectively, we find that the two-detector set-up can probe maximal CP violation and establish the neutrino mass ordering if sin{sup 2}2{theta}{sub 13} is 1.4x10{sup -4} and 2.7x10{sup -4}, respectively, or more. The sensitivity reach for sin{sup 2}2{theta}{sub 13} itself is 5.5x10{sup -4}. With a factor of 10 higher luminosity, the corresponding sin{sup 2}2{theta}{sub 13} reach of this set-up would be 1.8x10{sup -5}, 4.6x10{sup -5} and 5.3x10{sup -5} respectively for the above three performance indicators. CP violation can be discovered for 64% of the possible {delta}{sub CP} values for sin{sup 2}2{theta}{sub 13}{>=}10{sup -3} ({>=}8x10{sup -5}), for the standard luminosity (10 times enhanced luminosity). Comparable physics performance can be achieved in a set-up where data from CERN to INO-ICAL is combined with that from CERN to the Boulby mine in United Kingdom, a baseline of 1050 km.

  20. Does learning performance in horses relate to fearfulness, baseline stress hormone, and social rank?

    DEFF Research Database (Denmark)

    Christensen, Janne Winther; Ahrendt, Line Peerstrup; Lintrup, Randi

    2012-01-01

    The ability of horses to learn and remember new tasks is fundamentally important for their use by humans. Fearfulness may, however, interfere with learning, because stimuli in the environment can overshadow signals from the rider or handler. In addition, prolonged high levels of stress hormones can...... affect neurons within the hippocampus; a brain region central to learning and memory. In a series of experiments, we aimed to investigate the link between performance in two learning tests, the baseline level of stress hormones, measured as faecal cortisol metabolites (FCM), fearfulness, and social rank....... Twenty-five geldings (2 or 3 years old) pastured in one group were included in the study. The learning tests were performed by professional trainers and included a number of predefined stages during which the horses were gradually trained to perform exercises, using either negative (NR) or positive...

    Emotive imagery is a variant of systematic desensitization that has been used in the treatment of children's excessive fears. The purpose of this study was to evaluate the efficacy of emotive imagery as a fear reduction procedure using a multiple baseline design across subjects. Three children (6, 8 and 11 years old) with night-time fears participated in the study. The children showed marked behavioral improvements on a test for darkness toleration that was administered on alternate days in their homes. However, they reported experiencing very little fear in these tests. Over the intervention period fewer night-time behavioral disturbances were observed for two subjects. Parents expressed some concern about the darkness test but were satisfied with emotive imagery as a fear reduction procedure. As children's phobias are characterized by multiple processes, we recommend a combination of treatment procedures in clinical practice.

    This document has been produced to provide the definition and rationale for the Baseline Offshore Wind Farm established within IEA Wind Task 26--Cost of Wind Energy. The Baseline has been developed to provide a common starting point for country comparisons and sensitivity analysis on key offshore wind cost and value drivers. The baseline project reflects an approximate average of the characteristics of projects installed between 2012 and 2014, with the project life assumed to be 20 years. The baseline wind farm is located 40 kilometres (km) from construction and operations and maintenance (O&M) ports and from export cable landfall. The wind farm consists of 100 4-megawatt (MW) wind turbines mounted on monopile foundations in an average water depth of 25 metres (m), connected by 33-kilovolt (kV) inter-array cables. The arrays are connected to a single offshore substation (33kV/220kV) mounted on a jacket foundation, with the substation connected via a single 220kV export cable to an onshore substation, 10km from landfall. The wind farm employs a port-based O&M strategy using crew-transfer vessels.

    The SRC Process Area Design Baseline consists of six volumes. The first four were submitted to DOE on 9 September 1981. The fifth volume, summarizing the Category A Engineering Change Proposals (ECPs), was not submitted. The sixth volume, containing proprietary information on Kerr-McGee's Critical Solvent Deashing System, was forwarded to BRHG Synthetic Fuels, Inc. for custody, according to past instructions from DOE, and is available for perusal by authorized DOE representatives. DOE formally accepted the Design Baseline under ICRC Release ECP 4-1001, at the Project Configuration Control Board meeting in Oak Ridge, Tennessee on 5 November 1981. The documentation was then revised by Catalytic, Inc. to incorporate the Category B and C and Post-Baseline Engineering Change Proposals. Volumes I through V of the Revised Design Baseline, dated 22 October 1982, are nonproprietary and they were issued to the DOE via Engineering Change Notice (ECN) 4-1 on 23 February 1983. Volume VI again contains proprieary information on Kerr-McGee Critical Solvent Deashing System; it was issued to Burns and Roe Synthetic Fuels, Inc. Subsequently, updated process descriptions, utility summaries, and errata sheets were issued to the DOE and Burns and Roe Synthetic Fuels, Inc. on nonproprietary Engineering Change Notices 4-2 and 4-3 on 24 May 1983.

    The amount and complexity of patient-level data being collected in randomized-controlled trials offer both opportunities and challenges for developing personalized rules for assigning treatment for a given disease or ailment. For example, trials examining treatments for major depressive disorder are not only collecting typical baseline data such as age, gender, or scores on various tests, but also data that measure the structure and function of the brain such as images from magnetic resonance imaging (MRI), functional MRI (fMRI), or electroencephalography (EEG). These latter types of data have an inherent structure and may be considered as functional data. We propose an approach that uses baseline covariates, both scalars and functions, to aid in the selection of an optimal treatment. In addition to providing information on which treatment should be selected for a new patient, the estimated regime has the potential to provide insight into the relationship between treatment response and the set of baseline covariates. Our approach can be viewed as an extension of "advantage learning" to include both scalar and functional covariates. We describe our method and how to implement it using existing software. Empirical performance of our method is evaluated with simulated data in a variety of settings and also applied to data arising from a study of patients with major depressive disorder from whom baseline scalar covariates as well as functional data from EEG are available.

    A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavelengths requires baselines up to ~15 km. To develop and test this capability, a Long Baseline Campaign (LBC) was carried out from September to late November 2014, culminating in end-to-end observations, calibrations, and imaging of selected Science Verification (SV) targets. This paper presents an overview of the campaign and its main results, including an investigation of the short-term coherence properties and systematic phase errors over the long baselines at the ALMA site, a summary of the SV targets and observations, and recommendations for science observing strategies at long baselines. Deep ALMA images of the quasar 3C138 at 97 and 241 GHz are also compared to VLA 43 GHz results, demonstrating an agreement at a level of a few percent. As a result of the extensive program of LBC testing, the highly successful SV imaging at long...

    The first Search for Extra-Terrestrial Intelligence (SETI) conducted with very long baseline interferometry (VLBI) is presented. By consideration of the basic principles of interferometry, we show that VLBI is efficient at discriminating between SETI signals and human generated radio frequency interference (RFI). The target for this study was the star Gliese 581, thought to have two planets within its habitable zone. On 2007 June 19, Gliese 581 was observed for 8 hr at 1230-1544 MHz with the Australian Long Baseline Array. The data set was searched for signals appearing on all interferometer baselines above five times the noise limit. A total of 222 potential SETI signals were detected and by using automated data analysis techniques were ruled out as originating from the Gliese 581 system. From our results we place an upper limit of 7 MW Hz{sup -1} on the power output of any isotropic emitter located in the Gliese 581 system within this frequency range. This study shows that VLBI is ideal for targeted SETI including follow-up observations. The techniques presented are equally applicable to next-generation interferometers, such as the long baselines of the Square Kilometre Array.

    Earth observation platform is a host, the characteristics of the platform in some extent determines the ability for earth observation. Currently most developing platforms are satellite, in contrast carry out systematic observations with moon based Earth observation platform is still a new concept. The Moon is Earth's only natural satellite and is the only one which human has reached, it will give people different perspectives when observe the earth with sensors from the moon. Moon-based InSAR (SAR Interferometry), one of the important earth observation technology, has all-day, all-weather observation ability, but its uniqueness is still a need for analysis. This article will discuss key issues of geometric positioning and baseline parameters of moon-based InSAR. Based on the ephemeris data, the position, liberation and attitude of earth and moon will be obtained, and the position of the moon-base SAR sensor can be obtained by coordinate transformation from fixed seleno-centric coordinate systems to terrestrial coordinate systems, together with the Distance-Doppler equation, the positioning model will be analyzed; after establish of moon-based InSAR baseline equation, the different baseline error will be analyzed, the influence of the moon-based InSAR baseline to earth observation application will be obtained.

    The Automated Baseline Change Detection (ABCD) project is supported by the DOE Morgantown Energy Technology Center (METC) as part of its ER&WM cross-cutting technology program in robotics. Phase 1 of the Automated Baseline Change Detection project is summarized in this topical report. The primary objective of this project is to apply robotic and optical sensor technology to the operational inspection of mixed toxic and radioactive waste stored in barrels, using Automated Baseline Change Detection (ABCD), based on image subtraction. Absolute change detection is based on detecting any visible physical changes, regardless of cause, between a current inspection image of a barrel and an archived baseline image of the same barrel. Thus, in addition to rust, the ABCD system can also detect corrosion, leaks, dents, and bulges. The ABCD approach and method rely on precise camera positioning and repositioning relative to the barrel and on feature recognition in images. In support of this primary objective, there are secondary objectives to determine DOE operational inspection requirements and DOE system fielding requirements.

    The determination if the neutrino mixing matrix and mass-squared differences is one of the aims of neutrino physics today. This is a complicated affair, owing to the various parameter degeneracies. While the proposed 7500 km long 'magic baseline' experiment simplifies the task considerably, the intense beam required for such an experiment seems futuristic by current standards. As an alternative, we highlight the 'magical' properties of the 2540 km baseline. We propose a Superbeam experiment at this much shorter baseline with a narrow band NuMI-like beam, and demonstrate the ability of this single setup to distinguish between the two mass hierarchies. This, we show, is possible with a moderate exposure and by running the experiment in the neutrino mode only. Our results hold up to fairly small values of the mixing angle {theta}{sub 13} and irrespective of the value of the CP violating parameter. Unlike the magic baseline, it may also be possible to use this setup to measure CP violation in neutrino oscillation experiments. (authors)

    In intraoperative analysis of electromygraphic signals (EMG) for monitoring purposes, baseline artefacts frequently pose considerable problems. Since artefact sources in the operating room can only be reduced to a limited degree, signal-processing methods are needed to correct the registered data online without major changes to the relevant data itself. We describe a method for baseline correction based on "discrete wavelet transform" (DWT) and evaluate its performance compared to commonly used digital filters. EMG data from 10 patients who underwent removal of acoustic neuromas were processed. Effectiveness, preservation of relevant EMG patterns and processing speed of a DWT based correction method was assessed and compared to a range of commonly used Butterworth, Resistor-Capacitor and Gaussian filters. Butterworth and DWT filters showed better performance regarding artefact correction and pattern preservation compared to Resistor-Capacitor and Gaussian filters. Assuming equal weighting of both characteristics, DWT outperformed the other methods: While Butterworth, Resistor-Capacitor and Gaussian provided good pattern preservation, the effectiveness was low and vice versa, while DWT baseline correction at level 6 performed well in both characteristics. The DWT method allows reliable and efficient intraoperative baseline correction in real-time. It is superior to commonly used methods and may be crucial for intraoperative analysis of EMG data, for example for intraoperative assessment of facial nerve function.

NASA completed initial heat balance testing of a baseline engine. An additional 450 hours were run on ceramic regenerators and seals. Seal wear rates are very good, and the elastomeric mounting system was satisfactory. An engine/control oil supply system based on the power steering pump is successfully operating in baseline vehicles. The design of the upgraded engine power turbine nozzle actuator was finalized, and layouts of the inlet guide vane actuator are in process. A lock-up torque converter was installed in the free rotor vehicle. Baseline engine and vehicle testing of water injection and variable inlet guide vanes was completed. A thermal analysis of the gas generator is in process. A steady-state, full power analysis was made. A three-dimensional stress analysis of the compressor cover was made. The power turbine nozzle actuating system layout was completed. The analytical studies of the power turbine rotor bearings were completed. MTI completed the design of the gas generator rotor simulation fixture and is starting to build it. Optimized reduction gears were successfully tested in a baseline engine.

  3. [Growing old differently: Transdisciplinary perspective].

    Zimmermann, H-P

    2015-04-01

    Growing old differently: the phrase is intended to call something other to mind than merely the fact that images and forms of old age and aging have multiplied and diversified to an enormous extent. The suggestion put forward here is that otherness (as opposed to mere differences) should be positively reinforced. In other words, it is not just a matter of noting different forms of old age and aging but more than this, of seeking out opportunities for aging differently. In order to explore this, the article follows an older strand of theory, which has recently come to be frequently quoted in gerontology: the phenomenology of difference as reasoned analytically by Lévinas and Sartre and applied to gerontology by Améry and de Beauvoir. Here, opportunities for aging crucially depend on the way we look at it, how we observe and describe it and not least, how gerontology frames it. A distinction is made between two perspectives and their associated consequences for old age: alienation and alterity. Alienation means looking at old age above all as a disconcerting "other", as a perplexing, problematic deviation from the norm of vitality. Alterity, by contrast, refers to different options for living life in old age: options to be explored and opened up in contradistinction to cultural or academic alienation. Not least, the article appeals for diversity in scholarly approaches and for cross-disciplinary perspectives.

    International Coal Refining Company (ICRC), in cooperation with the Commonwealth of Kentucky has contracted with the United States Department of Energy (DOE) to design, build and operate a first-of-its-kind plant demonstrating the economic, environmental, socioeconomic and technical feasibility of the direct coal liquefaction process known as SRC-I. ICRC has made a massive commitment of time and expertise to design processes, plan and formulate policy, schedules, costs and technical drawings for all plant systems. These fully integrated plans comprise the Project Baseline and are the basis for all future detailed engineering, plant construction, operation, and other work set forth in the contract between ICRC and the DOE. Volumes I and II of the accompanying documents constitute the updated Project Baseline for the SRC-I two-stage liquefaction plant. International Coal Refining Company believes this versatile plant design incorporates the most advanced coal liquefaction system available in the synthetic fuels field. SRC-I two-stage liquefaction, as developed by ICRC, is the way of the future in coal liquefaction because of its product slate flexibility, high process thermal efficiency, and low consumption of hydrogen. The SRC-I Project Baseline design also has made important state-of-the-art advances in areas such as environmental control systems. Because of a lack of funding, the DOE has curtailed the total project effort without specifying a definite renewal date. This precludes the development of revised accurate and meaningful schedules and, hence, escalated project costs. ICRC has revised and updated the original Design Baseline to include in the technical documentation all of the approved but previously non-incorporated Category B and C and new Post-Baseline Engineering Change Proposals.

    Few studies have examined the correlates of real-world cardiac rehabilitation (CR) effectiveness. The objective of this study was to determine the relationship between baseline risk, behavioral attrition, and the number needed to treat (NNT) associated with CR. A retrospective study was conducted among 16,061 CR patients between 1995 and 2011 in Canada. Multiple logistic regression models were derived from patient characteristics and measured baseline risk (individual's risk of death within 3 years) and behavioral attrition (individual's risk of premature dropout). We examined the treatment efficacy of CR among nondropouts using a 20% relative risk reduction. Further sensitivity analyses were performed to assess the robustness of our assumptions. We assumed no efficacy among dropouts. Both baseline risk and behavioral attrition were independently associated with NNT, although baseline risk had a stronger association with NNT than behavioral attrition. Increasing age, lower baseline fitness, history of diabetes, hypertension, and greater comorbidities were associated with lower NNT. Being female, living alone, living in the lowest neighborhood income quintile, and greater adiposity were associated with higher NNT. The clinical effectiveness of CR is largely driven by the baseline risk rather than the behavioral attrition of the populations they serve. These findings have implications for risk stratification among those with greatest survival yields and programmatic needs. Copyright © 2016 Elsevier Inc. All rights reserved.

  7. Does neighborhood environment influence girls' pubertal onset? findings from a cohort study

    Full Text Available Abstract Background Pubertal onset occurs earlier than in the past among U.S. girls. Early onset is associated with numerous deleterious outcomes across the life course, including overweight, breast cancer and cardiovascular health. Increases in childhood overweight have been implicated as a key reason for this secular trend. Scarce research, however, has examined how neighborhood environment may influence overweight and, in turn, pubertal timing. The current study prospectively examined associations between neighborhood environment and timing of pubertal onset in a multi-ethnic cohort of girls. Body mass index (BMI was examined as a mediator of these associations. Methods Participants were 213 girls, 6-8 years old at baseline, in an on-going longitudinal study. The current report is based on 5 time points (baseline and 4 annual follow-up visits. Neighborhood environment, assessed at baseline, used direct observation. Tanner stage and anthropometry were assessed annually in clinic. Survival analysis was utilized to investigate the influence of neighborhood factors on breast and pubic hair onset, with BMI as a mediator. We also examined the modifying role of girls' ethnicity. Results When adjusting for income, one neighborhood factor (Recreation predicted delayed onset of breast and pubic hair development, but only for African American girls. BMI did not mediate the association between Recreation and pubertal onset; however, these associations persisted when BMI was included in the models. Conclusions For African American girls, but not girls from other ethnic groups, neighborhood availability of recreational outlets was associated with onset of breast and pubic hair. Given the documented risk for early puberty among African American girls, these findings have important potential implications for public health interventions related to timing of puberty and related health outcomes in adolescence and adulthood.

    This is a review of a prospective, community-based study with a follow-up period of 5years. It is a study of 328 participants aged 85 at baseline, of which 62% were female, 53% widows, and a third of them living alone. High blood pressure was observed in 75.9%, dyslipidaemia in 51.2%, and diabetes in 17.7%. At baseline the median Barthel Index was 95, the Spanish version of the Mini-Mental State Examination was 28, the Charlson index 1, the Mini Nutritional Assessment 25, the Gijón test 10, the visual analogue scale of the Quality of Life Test was 60, and with a mean of 6.1 prescription drugs. A lower quality of life was also associated with female gender, a phenotype of frailty, heart failure, and a high level of social risk. At 5years of follow-up, the mortality rate was high, with 138 (42.1%) of the population sample dying at the end of the period. It represents an annual mortality rate of 8.4%. Thus, a common denominator of this review has been the high importance of functionality and overall comorbidity factors associated with mortality in this very old age group, compared to other more traditional factors in younger populations. Several studies of frailty have also been assessed in this group, as well as falls, nutritional risk, diabetes and successful aging, including important aspects to better understand this population group.

    A 15-year-old girl was referred to a dentist complaining of parageusia, bad taste in the mouth, which started 9 months ago. Panoramic X-ray and non-enhanced computed tomography scan revealed multiple bilateral unilocular cysts in the mandible and maxilla, along with calcification of anterior part of the falx cerebri. She was eventually diagnosed with Gorlin-Goltz syndrome based on imaging and histopathologic finding of keratocystic odontogenic tumor.

    The aim of this study was to clarify whether decreases in baseline regional cerebral blood flow (rCBF) and in residual cerebral vasoreactivity (CVR), assessed by the acetazolamide (ACZ) challenge, can detect misery perfusion in patients with chronic cerebrovascular disease (CVD). Oxygen extraction fraction (OEF) and other haemodynamic parameters were measured in 115 patients (64{+-}9 years old) with unilateral cerebrovascular steno-occlusive disease (>70% stenosis) using {sup 15}O-gas and water PET. A significant elevation of OEF, by greater than the mean+2SD compared with healthy controls, was defined as misery perfusion. CBF, CVR determined by percent change in CBF after ACZ administration, OEF and other haemodynamic parameters in the territories of the bilateral middle cerebral arteries were analysed. Diagnostic accuracy for the detection of misery perfusion using the criteria determined by baseline CBF and CVR was evaluated in all patients and in only those patients with occlusive lesions. Ten of 24 patients with misery perfusion showed a significant reduction in CVR. Using criteria determined by significant decreases in CVR and baseline CBF, misery perfusion was detected with a sensitivity of 42% and a specificity of 95% in all patients. In patients with occlusive lesions (n=50), sensitivity was higher but specificity was slightly lower. The diagnostic accuracy of the threshold determined by baseline CBF alone was similar in all patients and in only those patients with occlusive lesions, and was higher than that achieved using the asymmetry index of OEF. Reductions in CVR and baseline CBF in the ACZ challenge for CVD would detect misery perfusion with high specificity. Reduction in baseline rCBF is more accurate than reduction in CVR alone for the detection of misery perfusion. (orig.)

    André Hajek

    Full Text Available To investigate time-dependent predictors of institutionalization in old age using a longitudinal approach.In a representative survey of the German general population aged 75 years and older predictors of institutionalization were observed every 1.5 years over six waves. Conditional fixed-effects logistic regressions (with 201 individuals and 960 observations were performed to estimate the effects of marital status, depression, dementia, and physical impairments (mobility, hearing and visual impairments on the risk of admission to old-age home or nursing home. By exploiting the longitudinal data structure using panel econometric models, we were able to control for unobserved heterogeneity such as genetic predisposition and personality traits.The probability of institutionalization increased significantly with occurrence of widowhood, depression, dementia, as well as walking and hearing impairments. In particular, the occurrence of widowhood (OR = 78.3, dementia (OR = 154.1 and substantial mobility impairment (OR = 36.7 were strongly associated with institutionalization.Findings underline the strong influence of loss of spouse as well as dementia on institutionalization. This is relevant as the number of old people (a living alone and (b suffering from dementia is expected to increase rapidly in the next decades. Consequently, it is supposed that the demand for institutionalization among the elderly will increase considerably. Practitioners as well as policy makers should be aware of these upcoming challenges.

    Full Text Available This study is aimed to understand transgender aging context in Brazil. Normal and abnormal were especially created by biological sciences. For being considered deviants, transgender people are not seen as human beings. They end up living in violent environments. Their life expectancy is low. Many of them do not believe to reach old age. They face a lot of prejudice and death threat. Those who get to what we call old age are considered survivals. This investigation was able to show satisfactorily their demands and needs. To be considered visible, they have to count on public policies to give them existence since their childhood. That way, we believe they will reach what we call old age with respect and dignity, already assured by the Universal Human Rights.

    The link between the blood count and a systemic inflammatory response (SIR) is indisputable and well described. Pretreatment hematological parameters may predict the overall clinical outcomes in many types of cancer. Thus, this study aims to systematically evaluate the relationship between baseline blood count levels and treatment response in rectal cancer patients treated with neoadjuvant chemoradiotherapy. From 2009-2015, 173 patients with locally advanced rectal cancer were retrospectively enrolled in the study and analyzed. The baseline blood count was recorded in all patients 1 week before chemoradiation. Tumor response was evaluated through pathologic findings. Blood count levels which included RBC (red blood cells), Hb (hemoglobin), PLT (platelet count), neutrophil count, WBC (white blood cells), NLR (neutrophil-to-lymphocyte ratio), and PLR (platelet-to-lymphocyte ratio) were analyzed in relation to tumor downstaging, pCR (pathologic complete response), OS (overall survival), and DFS (disease-free survival). Hb levels were associated with a response in logistic regression analysis: pCR (p = 0.05; OR 1.04, 95 % CI 1.00-1.07); T downstaging (p = 0.006; OR 1.03, 95 % CI 1.01-1.05); N downstaging (p = 0.09; OR 1.02, 95 % CI 1.00-1.04); T or N downstaging (p = 0.007; OR 1.04, 95 % CI 1.01-1.07); T and N downstaging (p = 0.02; OR 1.02, 95 % CI 1.00-1.04); Hb and RBC were the most significant parameters influencing OS; PLT was a negative prognostic factor for OS and DFS (p = 0.008 for OS); an NLR value of 2.8 was associated with the greatest significance for OS (p = 0.03) and primary tumor downstaging (p = 0.02). Knowledge of pretreatment hematological parameters appears to be an important prognostic factor in patients with rectal carcinoma. (orig.)

    The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

    Full Text Available BACKGROUND: Recent findings suggest that Alzheimer's disease (AD neuropathological features (neuritic plaques and NFTs are not strongly associated with dementia in extreme old (over 90 years of age and compel a search for neurobiological indices of dementia in this rapidly growing segment of the elderly population. We sought to characterize transcriptional and protein profiles of dementia in the oldest-old. METHODS AND FINDINGS: Gene and protein expression changes relative to non-demented age-matched controls were assessed by two microarray platforms, qPCR and Western blot in different regions of the brains of oldest-old and younger old persons who died at mild or severe stages of dementia. Our results indicate that: i consistent with recent neuropathological findings, gene expression changes associated with cognitive impairment in oldest-old persons are distinct from those in cognitively impaired youngest-old persons; ii transcripts affected in young-old subjects with dementia participate in biological pathways related to synaptic function and neurotransmission while transcripts affected in oldest-old subjects with dementia are associated with immune/inflammatory function; iii upregulation of immune response genes in cognitively intact oldest-old subjects and their subsequent downregulation in dementia suggests a potential protective role of the brain immune-associated system against dementia in the oldest-old; iv consistent with gene expression profiles, protein expression of several selected genes associated with the inflammatory/immune system in inferior temporal cortex is significantly increased in cognitively intact oldest-old persons relative to cognitively intact young-old persons, but impaired in cognitively compromised oldest-old persons relative to cognitively intact oldest-old controls. CONCLUSIONS: These results suggest that disruption of the robust immune homeostasis that is characteristic of oldest-old individuals who avoided

  17. Comparison of baseline removal methods for laser-induced breakdown spectroscopy of geological samples

    2016-12-01

    This project examines the causes, effects, and optimization of continuum removal in laser-induced breakdown spectroscopy (LIBS) to produce the best possible prediction accuracy of elemental composition in geological samples. We compare prediction accuracy resulting from several different techniques for baseline removal, including asymmetric least squares (ALS), adaptive iteratively reweighted penalized least squares (Air-PLS), fully automatic baseline correction (FABC), continuous wavelet transformation, median filtering, polynomial fitting, the iterative thresholding Dietrich method, convex hull/rubber band techniques, and a newly-developed technique for Custom baseline removal (BLR). We assess the predictive performance of these methods using partial least-squares analysis for 13 elements of geological interest, expressed as the weight percentages of SiO2, Al2O3, TiO2, FeO, MgO, CaO, Na2O, K2O, and the parts per million concentrations of Ni, Cr, Zn, Mn, and Co. We find that previously published methods for baseline subtraction generally produce equivalent prediction accuracies for major elements. When those pre-existing methods are used, automated optimization of their adjustable parameters is always necessary to wring the best predictive accuracy out of a data set; ideally, it should be done for each individual variable. The new technique of Custom BLR produces significant improvements in prediction accuracy over existing methods across varying geological data sets, instruments, and varying analytical conditions. These results also demonstrate the dual objectives of the continuum removal problem: removing a smooth underlying signal to fit individual peaks (univariate analysis) versus using feature selection to select only those channels that contribute to best prediction accuracy for multivariate analyses. Overall, the current practice of using generalized, one-method-fits-all-spectra baseline removal results in poorer predictive performance for all methods. The

    To evaluate the characteristic CT findings of neuroblastoma, we studied neuroblastomas. We analysed CT findings of available 25 cases among pathologically proved 51 neuroblastomas from Jan. 1983 to Sept. 1990. The most frequent site of origin is adrenal gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows: Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently seperated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymph nodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neuroblastomas and 25% of mediastinal neuroblastomas. The most common organ or contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

    2015-01-01

    Infrared-faint radio sources (IFRS) form a new class of galaxies characterised by radio flux densities between tenths and tens of mJy and faint or absent infrared counterparts. It has been suggested that these objects are radio-loud active galactic nuclei (AGNs) at significant redshifts (z >~ 2). Whereas the high redshifts of IFRS have been recently confirmed based on spectroscopic data, the evidence for the presence of AGNs in IFRS is mainly indirect. So far, only two AGNs have been unquestionably confirmed in IFRS based on very long baseline interferometry (VLBI) observations. In this work, we test the hypothesis that IFRS contain AGNs in a large sample of sources using VLBI. We observed 57 IFRS with the Very Long Baseline Array (VLBA) down to a detection sensitivity in the sub-mJy regime and detected compact cores in 35 sources. Our VLBA detections increase the number of VLBI-detected IFRS from 2 to 37 and provide strong evidence that most - if not all - IFRS contain AGNs. We find that IFRS have a marginal...

    1995-04-01

    The Salmon Site (SS), formerly the Tatum Dome Test Site, located in Mississippi was the site of two nuclear and two gas explosion tests conducted between 1964 and 1970. A consequence of these testing activities is that radionuclides were released into the salt dome, where they are presently contained. During reentry drilling and other site activities, incidental liquid and solid wastes that contained radioactivity were generated, resulting in some soil, ground water and equipment contamination. As part of the remedial investigation effort, a Baseline Ecological Risk Assessment was conducted at the SS. The purpose is to gauge ecological and other environmental impacts attributable to past activities at the former test facility. The results of this facility-specific baseline risk assessment are presented in this document.

    Long-baseline neutrino oscillation physics in the U.S. is centered at the Fermi National Accelerator Laboratory (FNAL), in particular at the Neutrinos at the Main Injector (NuMI) beamline commissioned in 2004-2005. Already, the MINOS experiment has published its first results confirming the disappearance of {nu}{sub {mu}}'s across a 735 km baseline. The forthcoming NO{nu}A experiment will search for the transition {nu}{sub {mu}}{yields}{nu}{sub e} and use this transition to understand the mass heirarchy of neutrinos. These, as well as other conceptual ideas for future experiments using the NuMI beam, will be discussed. The turn-on of the NuMI facility has been positive, with over 310 kW beam power achieved. Plans for increasing the beam intensity once the Main Injector accelerator is fully-dedicated to the neutrino program will be presented.

  7. Coral reef baselines: how much macroalgae is natural?

    2014-03-15

    Identifying the baseline or natural state of an ecosystem is a critical step in effective conservation and restoration. Like most marine ecosystems, coral reefs are being degraded by human activities: corals and fish have declined in abundance and seaweeds, or macroalgae, have become more prevalent. The challenge for resource managers is to reverse these trends, but by how much? Based on surveys of Caribbean reefs in the 1970s, some reef scientists believe that the average cover of seaweed was very low in the natural state: perhaps less than 3%. On the other hand, evidence from remote Pacific reefs, ecological theory, and impacts of over-harvesting in other systems all suggest that, historically, macroalgal biomass may have been higher than assumed. Uncertainties about the natural state of coral reefs illustrate the difficulty of determining the baseline condition of even well studied systems.

    Node-perturbation learning is a type of statistical gradient descent algorithm that can be applied to problems where the objective function is not explicitly formulated, including reinforcement learning. It estimates the gradient of an objective function by using the change in the object function in response to the perturbation. The value of the objective function for an unperturbed output is called a baseline. Cho et al. proposed node-perturbation learning with a noisy baseline. In this paper, we report on building the statistical mechanics of Cho's model and on deriving coupled differential equations of order parameters that depict learning dynamics. We also show how to derive the generalization error by solving the differential equations of order parameters. On the basis of the results, we show that Cho's results are also apply in general cases and show some general performances of Cho's model.

    Distributed platforms play an important role in aerospace remote sensing, radar navigation, and wireless communication applications. However, besides the requirement of high accurate time and frequency synchronization for coherent signal processing, the baseline between the transmitting platform and receiving platform and the orientation of platform towards each other during data recording must be measured in real time. In this paper, we propose an improved pulsed duplex microwave ranging approach, which allows determining the spatial baseline and orientation between distributed aerospace platforms by the proposed high-precision time-interval estimation method. This approach is novel in the sense that it cancels the effect of oscillator frequency synchronization errors due to separate oscillators that are used in the platforms. Several performance specifications are also discussed. The effectiveness of the approach is verified by simulation results.

    Summary. The optimal duration of treatment for hepatitis C virus (HCV) infections is highly variable but critical for achieving cure (sustained virological response, SVR). We prospectively investigated the impact of age, fibrosis, baseline viraemia and genotype on the early viral kinetics...... above 400 000 IU/mL were strongly associated with slower second phase declines of HCV RNA. Genotype 2/3 infections responded more rapidly than genotype 1, reaching week 4 negativity (RVR) in 59%vs 22%. We conclude that baseline response predictors such as age, fibrosis and viral load were well reflected...... by the early viral kinetics as assessed by repeated HCV RNA quantifications. The kinetic patterns and the high relapse rate in genotype 2/3 patients without RVR suggest that this group might benefit from treatment durations longer than 24 weeks....

    Hälser, Alexis

    2015-01-01

    Accelerator based long baseline neutrino experiments require precise neutrino fl ux predictions to reach their physics goals. These experiments are commonly based on a set of two detectors. At the near detector, cross section measurements are performed and the neutrino fl ux can be observed before oscillation, while at the far detector the signal for neutrino oscillations is studied. An accurate knowledge on hadron production is mandatory in order to predict the neutrino fluxes. The NA61/SHINE facility at the CERN SPS has proven its ability to deliver high quality measurements of hadron production for the long baseline neutrino experiments.

    2016-01-01

    One of the greatest challenges for sensorimotor adaptation to the spaceflight environment is the large variability in symptoms, and corresponding functional impairments, from one crewmember to the next. This renders preflight training and countermeasure development difficult, as a "one-size-fits-all" approach is inappropriate. Therefore, it would be highly advantageous to know ahead of time which crewmembers might have more difficulty adjusting to the novel g-levels inherent to spaceflight. This information could guide individually customized countermeasures, which would enable more efficient use of crew time and provide better outcomes. The principal aim of this work is to look for baseline performance metrics that relate to locomotor adaptability. We propose a novel hypothesis that considers baseline inter-trial correlations, the trial-to-trial fluctuations ("noise") in motor performance, as a predictor of individual adaptive capabilities.

We now propose an analogous predictive mechanisms in the locomotor system.

    In the last three years, the European Geodetic Very Long Baseline Interferometry (VLBI) Network has grown to a total of six fixed antennas placed in Germany, Italy, Spain and Sweden, all equipped with the standard geodetic VLBI instrumentation and data recording systems. During this period of time, several experiments have been carried out using this interferometer providing data of very high quality due to the excellent sensitivity and performance of the European stations. The purpose of this paper is to study the consistency of the VLBI geodetic results on the European baselines with respect to the different degrees of freedom in the analysis procedure. Used to complete this study were both real and simulated data sets, two different software packages (OCCAM 3.0 and CALC 7.4/SOLVE), and a variety of data analysis strategies.

    Since 1994 Lawrence Livermore National Laboratory (LLNL), with the help of several other laboratories and university groups, has been the lead laboratory for the Plutonium Immobilization Project (PIP). This involves, among other tasks, the development of a formulation and a fabrication process for a ceramic to be used in the immobilization of excess weapons-usable plutonium. This report reviews the history of the project as it relates to the development of the ceramic form. It describes the sample test plan for the pyrochlore-rich ceramic formulation that was selected, and it specifies the baseline formulation that has been adopted. It also presents compositional specifications (e.g. precursor compositions and mixing recipes) and other form and process specifications that are linked or potentially linked to the baseline formulation.

    Wide baseline matching is the state of the art for object recognition and image registration problems in computer vision. Though effective, the computational expense of these algorithms limits their application to many real-world problems. The performance of wide baseline matching algorithms may be improved by using a graphical processing unit as a fast multithreaded co-processor. In this paper, we present an implementation of the difference of Gaussian feature extractor, based on the CUDA system of GPU programming developed by NVIDIA, and implemented on their hardware. For a 2000x2000 pixel image, the GPU-based method executes nearly thirteen times faster than a comparable CPU-based method, with no significant loss of accuracy.

    The MicroBooNE experiment is the first of three detectors of the Fermilab short-baseline neutrino program that started operation in the Booster Neutrino Beamline in October 2015 [1]. When completed, the three-detector lineup will explore short-baseline neutrino oscillations and will be sensitive to sterile neutrino scenarios. MicroBooNE in itself is now starting its own physics program, with the measurement of neutrino-argon cross sections in the ~1GeV range being one of its main physics goals. These proceedings describe the status of the detector, the start of operation, and the automated reconstruction of the first neutrino events observed with MicroBooNE. Prospects for upcoming cross section measurements are also given.

    Environmental baseline documents and NEPA compliance guides should be carried in every NEPA implementation ``tool kit``. These two indispensable tools can play a major role in avoiding repeated violations of NEPA requirements that have occurred over the past 26 years. This paper describes these tools, discusses their contents, and explains how they are used to prepare better NEPA documents more cost-effectively. Focus is on experience at Sandia Laboratories (NM).

    Summary Abstract Sharks and other large predators are scarce on most coral reefs, but studies of their historical ecology provide qualitative evidence that predators were once numerous in these ecosystems. Quantifying density of sharks in the absence of humans (baseline) is, however, hindered by a paucity of pertinent time-series data. Recently researchers have used underwater visual surveys, primarily of limited spatial extent or nonstandard design, to infer negative associations between ree...

    2009-01-01

    When the cycle slips take place in the attitude determination of a moving platform, the precision of the attitude will be impaired badly. A method of cycle slip detection and correction is proposed, which is suitable to the dynamic measurement using GPS carrier phase: the cycle slips detection is first achieved by triple difference observables, then the cycle slips correction is performed with baseline length constraint. The simulation results show that the proposed method is effective to the dynamic cycle slips problem.

    2015-05-01

    Recent Better Buying Power (BBP) initiative for improving DoD's effectiveness in developing complex systems includes "Owning the Technical Baseline" (OTB). This paper presents an innovative approach for the development of a "Resilient Program" Technical Baseline Framework (PTBF). The framework provides a recipe for generating the "Resilient Program2" Technical Baseline (PTB) components using the Integrated Program Management (IPM) approach to integrate Key Program Elements (KPEs)3 with System Engineering (SE) process/tools, acquisition policy/process/tools, Cost and Schedule estimating tools, DOD Architecture Framework (DODAF) process/tools, Open System Architecture (OSA) process/tools, Risk Management process/tools, Critical Chain Program Management (CCPM) process, and Earned Value Management System (EVMS) process/tools. The proposed resilient framework includes a matrix that maps the required tools/processes to technical features of a comprehensive reference U.S. DOD "owned" technical baseline. Resilient PTBF employs a new Open System Approach (OSAP) combining existing OSA4 and NOA (Naval Open Architecture) frameworks, supplemented by additional proposed OA (Open Architecture) principles. The new OSAP being recommended to SMC (Space and Missiles Systems Center) presented in this paper is referred to as SMC-OSAP5. Resilient PTBF and SMC-OSAP conform to U.S. DOD Acquisition System (DAS), Joint Capabilities Integration and Development System (JCIDS), and DODAF processes. The paper also extends Ref. 21 on "Program Resiliency" concept by describing how the new OSAP can be used to align SMC acquisition management with DOD BBP 3.0 and SMC's vison for resilient acquisition and sustainment efforts.

    We study parameter degeneracies that can occur in long-baseline neutrino appearance experiments due to nonstandard interactions (NSI). For a single off-diagonal NSI parameter, and neutrino and antineutrino measurements at a single L/E, there exists a continuous four-fold degeneracy (related to the mass hierarchy and $\\theta_{23}$ octant) that renders the mass hierarchy, octant, and CP phase unknowable.

    We show that, in the framework of three light neutrino species with hierarchical masses and assuming no fine tuning between the entries of the neutrino mass matrix, one can use the solar neutrino data to obtain information on the element U(e3) of the lepton mixing matrix. Conversely, a measurement of U(e3) in atmospheric or long baseline accelerator or reactor neutrino experiments would help discriminate between possible oscillation solutions of the solar neutrino problem.

    Full Text Available This study is aimed to understand transgender aging context in Brazil. Normal and abnormal were especially created by biological sciences. For being considered deviants, transgender people are not seen as human beings. They end up living in violent environments. Their life expectancy is low. Many of them do not believe to reach old age. They face a lot of prejudice and death threat. Those who get to what we call old age are considered survivals. This investigation was able to show satisfactorily their demands and needs. To be considered visible, they have to count on public policies to give them existence since their childhood. That way, we believe they will reach what we call old age with respect and dignity, already assured by theUniversal Human Rights.

    2009-07-01

    Stereo matching is one of the most important branches in computer vision. In this paper, an algorithm is proposed for wide-baseline stereo vision matching. Here, a novel scheme is presented called double topological relationship consistency (DCTR). The combination of double topological configuration includes the consistency of first topological relationship (CFTR) and the consistency of second topological relationship (CSTR). It not only sets up a more advanced model on matching, but discards mismatches by iteratively computing the fitness of the feature matches and overcomes many problems of traditional methods depending on the powerful invariance to changes in the scale, rotation or illumination across large view changes and even occlusions. Experimental examples are shown where the two cameras have been located in very different orientations. Also, epipolar geometry can be recovered using RANSAC by far the most widely method adopted possibly. By the method, we can obtain correspondences with high precision on wide baseline matching problems. Finally, the effectiveness and reliability of this method are demonstrated in wide-baseline experiments on the image pairs.

    Very Long Baseline Atom Interferometry (VLBAI) has applications in high-accuracy absolute gravimetry, gravity-gradiometry, and for tests of fundamental physics. Extending the baseline of atomic gravimeters from tens of centimeters to meters opens the route towards competition with superconducting gravimeters. The VLBAI-test stand will consist of a 10m-baseline atom interferometer allowing for free fall times of seconds. In order to suppress environmental noise, the facility utilizes a state-of-the-art vibration isolation platform and a three-layer magnetic shield. We envisage a resolution of local gravitational acceleration of 5 .10-10 m/ s2 with sub-ppb inaccuracy. Operation as a gradiometer will allow to resolve the gravity gradient at a resolution of 5 .10-10 1/ s2. The operation of VLBAI as a differential dual-species gravimeter using ultracold mixtures of Yb and Rb atoms enables quantum tests of the universality of free fall (UFF) at an unprecedented level, with the potential to surpass the accuracy of the best experiments to date. We report on a quantum test of the UFF using two different chemical elements, 39 K and 87 Rb, reaching a 100 ppb inaccuracy and show the potential of UFF tests in VLBAI at an inaccuracy of 10-13 and beyond.

    2009-01-01

    We propose a realistic Beta-Beam experiment with four source ions and two baselines for the best possible sensitivity to theta_{13}, CP violation and mass hierarchy. Neutrinos from 18Ne and 6He with Lorentz boost gamma=350 are detected in a 500 kton water Cerenkov detector at a distance L=650 km (first oscillation peak) from the source. Neutrinos from 8B and 8Li are detected in a 50 kton magnetized iron detector at a distance L=7000 km (magic baseline) from the source. Since the decay ring requires a tilt angle of 34.5 degrees to send the beam to the magic baseline, the far end of the ring has a maximum depth of d=2132 m for magnetic field strength of 8.3 T, if one demands that the fraction of ions that decay along the straight sections of the racetrack geometry decay ring (called livetime) is 0.3. We alleviate this problem by proposing to trade reduction of the livetime of the decay ring with the increase in the boost factor of the ions, such that the number of events at the detector remains almost the same....

  14. Forecasting Sensorimotor Adaptability from Baseline Inter-Trial Correlations

    2014-01-01

    One of the greatest challenges surrounding adaptation to the spaceflight environment is the large variability in symptoms, and corresponding functional impairments, from one crewmember to the next. This renders preflight training and countermeasure development difficult, as a "one-size-fits-all" approach is inappropriate. Therefore, it would be highly advantageous to know ahead of time which crewmembers might have more difficulty adjusting to the novel g-levels inherent to spaceflight. Such knowledge could guide individually customized countermeasures, which would enable more efficient use of crew time, both preflight and inflight, and provide better outcomes. The primary goal of this project is to look for a baseline performance metric that can forecast sensorimotor adaptability without exposure to an adaptive stimulus. We propose a novel hypothesis that considers baseline inter-trial correlations, the trial-to-trial fluctuations in motor performance, as a predictor of individual sensorimotor adaptive capabilities. To-date, a strong relationship has been found between baseline inter-trial correlations and adaptability in two oculomotor systems. For this project, we will explore an analogous predictive mechanism in the locomotion system. METHODS: Baseline Inter-trial Correlations: Inter-trial correlations specify the relationships among repeated trials of a given task that transpire as a consequence of correcting for previous performance errors over multiple timescales. We can quantify the strength of inter-trial correlations by measuring the decay of the autocorrelation function (ACF), which describes how rapidly information from past trials is "forgotten." Processes whose ACFs decay more slowly exhibit longer-term inter-trial correlations (longer memory processes), while processes whose ACFs decay more rapidly exhibit shorterterm inter-trial correlations (shorter memory processes). Longer-term correlations reflect low-frequency activity, which is more easily

    This paper presents an innovative approach to develop a Commercial Satellite Communications (COMSATCOM) service Technical Baseline (TB) and associated Program Baseline (PB) strategy using Portable Pool Bandwidth (PPBW) concept. The concept involves trading of the purchased commercial transponders' Bandwidths (BWs) with existing commercial satellites' bandwidths participated in a "designated pool bandwidth"3 according to agreed terms and conditions. Space Missile Systems Center (SMC) has been implementing the Better Buying Power (BBP 3.0) directive4 and recommending the System Program Offices (SPO) to own the Program and Technical Baseline (PTB) [1, 2] for the development of flexible acquisition strategy and achieving affordability and increased in competition. This paper defines and describes the critical PTB parameters and associated requirements that are important to the government SPO for "owning" an affordable COMSATCOM services contract using PPBW trading concept. The paper describes a step-by-step approach to optimally perform the PPBW trading to meet DoD and its stakeholders (i) affordability requirement, and (ii) fixed and variable bandwidth requirements by optimizing communications performance, cost and PPBW accessibility in terms of Quality of Services (QoS), Bandwidth Sharing Ratio (BSR), Committed Information Rate (CIR), Burstable Information Rate (BIR), Transponder equivalent bandwidth (TPE) and transponder Net Presence Value (NPV). The affordable optimal solution that meets variable bandwidth requirements will consider the operating and trading terms and conditions described in the Fair Access Policy (FAP).

    After establishing the diagnosis of an insulinoma, most surgeons prefer preoperative localization. Selective arteriography is usually considered the gold standard for this purpose. Recently, computed tomography (CT) and preoperative US have contended the role to angiography. MRI has been used in few cases of endocrine pancreatic tumors, and its role in this particular field has to be defined. Between November 1988-September 1990 7 adult patients who had undergone surgery were evaluated. Eight tumors were resected in 6 patients who were cured; in an 18-year-old woman surgical treatment was unsuccessful. Arterio-graphy, CT, preoperative US, MRI and intraoperative US detected 2, 6, 6, 5 and 6 tumors respectively. Two insulinomas (0.2 and 0.7 cm) were found at histologic examination in resected specimen. The ability of intra-operative US and careful surgical exploration to resolve more than 90 percent of cases makes the preoperative use of arteriography and CT questionable value. If further experience confirms these findings, US and MRI may suffice. (author). 13 refs.; 3 figs.; 1 tab.

  18. Do older adults with chronic low back pain differ from younger adults in regards to baseline characteristics and prognosis?

    2017-05-01

    Low back pain (LBP) in older adults is poorly understood because the vast majority of the LBP research has focused on the working aged population. The aim of this study was to compare older adults consulting with chronic LBP to middle aged and young adults consulting with chronic LBP, in terms of their baseline characteristics, and pain and disability outcomes over 1 year. Data were systematically collected as part of routine care in a secondary care spine clinic. At initial presentation patients answered a self-report questionnaire and underwent a physical examination. Patients older than 65 were classified as older adults and compared to middle aged (45-65 years old) and younger adults (17-44 years old) for 10 baseline characteristics. Pain intensity and disability were collected at 6 and 12 month follow-ups and compared between age groups. A total of 14,479 participants were included in the study. Of these 3087 (21%) patients were older adults, 6071 (42%) were middle aged and 5321 (37%) were young adults. At presentation older adults were statistically different to the middle aged and younger adults for most characteristics measured (e.g. less intense back pain, more leg pain and more depression); however, the differences were small. The change in pain and disability over 12 months did not differ between age groups. This study found small baseline differences in older people with chronic LBP compared to middle aged and younger adults. There were no associations between age groups and the clinical course. Small baseline differences exist in older people with chronic low back pain compared to middle aged and younger adults referred to secondary care for chronic low back pain. Older adults present with slightly less intense low back pain but slightly more intense leg pain. Changes in pain intensity and disability over a 12 month period were similar across all age groups. © 2017 European Pain Federation - EFIC®.

    Expectation of locations and low-level features increases activity in extrastriate visual areas even in the absence of a stimulus, but it is unclear whether or how expectation of higher-level stimulus properties affects visual responses. Here, we used event-related functional magnetic resonance imaging (fMRI) to test whether category expectation affects baseline and stimulus-evoked activity in higher-level, category-selective inferotemporal (IT) visual areas. Word cues indicating an image category (FACE or HOUSE) were followed by a delay, then a briefly presented image of a face or a house. On most trials, the cue correctly predicted the upcoming stimulus. Baseline activity in regions within the fusiform face area (FFA) and parahippocampal place area (PPA) was modulated such that activity was higher during expectation of the preferred (e.g., FACE for FFA) vs. non-preferred category. Stimulus-evoked responses reflected an initial bias (higher overall activity) followed by increased selectivity (greater difference between activity to a preferred vs. non-preferred stimulus) after expectation of the preferred vs. non-preferred category. Consistent with the putative role of a frontoparietal network in top-down modulation of activity in sensory cortex, expectation-related activity in several frontal and parietal areas correlated with the magnitude of baseline shifts in the FFA and PPA across subjects. Furthermore, expectation-related activity in lateral prefrontal cortex also correlated with the magnitude of expectation-based increases in stimulus selectivity in IT areas. These findings demonstrate that category expectation influences both baseline and stimulus-evoked activity in category-selective inferotemporal visual areas, and that these modulations may be driven by a frontoparietal attentional control network.

  20. The effects of nicotine on cognition are dependent on baseline performance.

    Since cholinergic neurotransmission plays a major role in cognition, stimulation of the nicotinic acetylcholine receptor may be a target for cognitive enhancement. While nicotine improves performance on several cognitive domains, results of individual studies vary. A possible explanation for these findings is that the effect of nicotine administration may be dependent on baseline cognitive function, where subjects with a suboptimal cognitive performance may benefit from nicotine, while subjects who already perform optimally may show a decline in performance after nicotinic stimulation. We conducted a double-blind randomised placebo-controlled crossover trial, examining the effects of placebo, 1, and 2mg of nicotine on cognition in young (n=16, age 18-30 years) and healthy elderly (n=16, age 60-75 years) subjects. We hypothesised that the elderly would benefit more from nicotine compared to young subjects, as normal ageing is associated with decreases in cognitive function. Attention, working memory, visual memory, information-processing speed, psychomotor function, stereotypy, and emotion recognition were assessed. Compared to the young volunteers, the elderly performed significantly worse on psychomotor function and emotion recognition in the placebo condition. Nicotine had no effect in the young volunteers and decreased performance on working memory and visual memory in the elderly. Contrary to our hypothesis, the effect of nicotine was dependent on baseline performance in both the groups, with subjects with lower baseline performance benefiting from nicotine administration, while those with higher baseline performance performed worse after nicotine administration. This suggests that subjects with lower cognitive performance, irrespective of age, may benefit from nicotine.

    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

    Gallstone ileus is a rare complication of recurrent gallstone cholecystitis. The classic radiographic triad of small bowel obstruction, pneumobilia and ectopic gallstone on abdominal plain radiograph is described with CT imaging. Because of the better resolution of CT compared with abdominal radiography and its recent accession to emergency use, radiologists should be aware of CT findings of gallstone ileus. We report a case in which gallstone ileus was initially diagnosed by CT. (orig.)

    Context. Infrared-faint radio sources (IFRS) form a new class of galaxies characterised by radio flux densities between tenths and tens of mJy and faint or absent infrared counterparts. It has been suggested that these objects are radio-loud active galactic nuclei (AGNs) at significant redshifts (z ≳ 2). Aims: Whereas the high redshifts of IFRS have been recently confirmed based on spectroscopic data, the evidence for the presence of AGNs in IFRS is mainly indirect. So far, only two AGNs have been unquestionably confirmed in IFRS based on very long baseline interferometry (VLBI) observations. In this work, we test the hypothesis that IFRS contain AGNs in a large sample of sources using VLBI. Methods: We observed 57 IFRS with the Very Long Baseline Array (VLBA) down to a detection sensitivity in the sub-mJy regime and detected compact cores in 35 sources. Results: Our VLBA detections increase the number of VLBI-detected IFRS from 2 to 37 and provide strong evidence that most - if not all - IFRS contain AGNs. We find that IFRS have a marginally higher VLBI detection fraction than randomly selected sources with mJy flux densities at arcsec-scales. Moreover, our data provide a positive correlation between compactness - defined as the ratio of milliarcsec- to arcsec-scale flux density - and redshift for IFRS, but suggest a decreasing mean compactness with increasing arcsec-scale radio flux density. Based on these findings, we suggest that IFRS tend to contain young AGNs whose jets have not formed yet or have not expanded, equivalent to very compact objects. We found two IFRS that are resolved into two components. The two components are spatially separated by a few hundred milliarcseconds in both cases. They might be components of one AGN, a binary black hole, or the result of gravitational lensing.

    Rapamycin is known to extend lifespan. We conducted a randomized placebo-controlled study of enteric rapamycin-treatment to evaluate its effect on physical function in old low capacity runner (LCR) rats, a rat model selected from diverse genetic background for low intrinsic aerobic exercise capacity without genomic manipulation and characterized by increased complex disease risks and aging phenotypes. The study was performed in 12 male and 16 female LCR rats aged 16-22 months at baseline. The treatment group was fed with rapamycin-containing diet pellets at approximately 2.24mg/kg body weight per day and the placebo group with the same diet without rapamycin for six months. Observation was extended for additional 2 months. Physical function measurements include grip strength measured as maximum tensile force using a rat grip strength meter and maximum running distance (MRD) using rat physical treadmill test. The results showed that rapamycin improved grip strength by 13% (p=.036) and 60% (p=.001) from its baseline in female and male rats, respectively. Rapamycin attenuated MRD decline by 66% (p=.001) and 46% (p=.319) in females and males, respectively. These findings provide initial evidence for beneficial effect of rapamycin on physical functioning in an aging rat model of high disease risks with significant implication in humans.

    Traffic injuries have become a major health-related issue to school-aged children. To study this type of injury with numerical simulations, a finite element model was developed to represent the full body of a 10-year-old (YO) child. The model has been validated against test data at both body-part and full-body levels in previous studies. Representing only the average 10-YO child, this model did not include subject-specific attributes, such as the variations in size and shape among different children. In this paper, a new modeling approach was used to morph this baseline model to a subject-specific model, based on anthropometric data collected from pediatric subjects. This mesh-morphing method was then used to rapidly morph the baseline mesh into the subject-specific geometry while maintaining a good mesh quality. The morphed model was subsequently applied to simulate a real-world motor vehicle crash accident. A lung injury observed in the accident was well captured by the subject-specific model. The findings of this study demonstrate the feasibility of the proposed morphing approach to develop subject-specific human models, and confirm their capability in prediction of traffic injuries.

  17. Constraining proposed combinations of ice history and Earth rheology using VLBI determined baseline length rates in North America

    We predict the present-day rates of change of the lengths of 19 North American baselines due to the glacial isostatic adjustment process. Contrary to previously published research, we find that the three dimensional motion of each of the sites defining a baseline, rather than only the radial motions of these sites, needs to be considered to obtain an accurate estimate of the rate of change of the baseline length. Predictions are generated using a suite of Earth models and late Pleistocene ice histories, these include specific combinations of the two which have been proposed in the literature as satisfying a variety of rebound related geophysical observations from the North American region. A number of these published models are shown to predict rates which differ significantly from the VLBI observations.

    To analyze the MR findings of cyclosporine-induced neurotoxicity in patients receiving high dose of cyclosporine and to suggest the possible pathogenetic mechanism. The cases of seven patients (2 males, 5 females;18-36 years old) who suffered seizures after receiving high-dose cyclosporine for bone marrow transplantation due to diseases such as aplastic anemia or leukemia were retrospectively reviewed. We evaluated the location and pattern of abnormal signal intensity seen on T2 weighted images, the presence of contrast enhancement, and the changes seen on follow-up MR performed at intervals of 12-30 days after initial MR in five of seven patients. We analyzed levels of blood cyclosporine and magnesium, and investigated the presence of hypertension at the sity of the seizure. Locations of the lesions were bilateral(n=3D5), unilateral(n=3D2), parietal(n=3D6), occipital(n=3D6), temporal(n=3D4), and in the frontal lobe(n=3D3). Frontal lesions showed high signal intensities in the borderline ischemic zone of the frontal lobe between the territory of the anterior and middle cerebral arteries. In six of the seven patients, cortical and subcortical areas including subcortical U-fibers were seen on T2-weighted images to be involved in the parietooccipital lobes. Only one of the seven showed high signal intensity in the left basal ganglia. All lesions showed high signal intensity on T2-weighted images, and iso to low signal intensity on T1-weighted. In five of seven patients there was no definite enhancement, but in the other two, enhancement was slight. In four of seven patients seizures occurred within high therapeutic ranges(250-450ng/ml), while others suffered such attacks at levels below the therapeutic range. After cyclospirine was administered at a reduced dosage or stopped, follow-up MR images showed the complete or near-total disappearance of the abnormal findings previously described. Only two patients had hypertension, and the others normotension. Five of the

    To determine whether baseline urgency urinary incontinence (UUI) episodes predict the need for increased doses of fesoterodine in patients with overactive bladder (OAB), as clinicians would benefit from data that help to predict which patients require higher doses of antimuscarinics to manage UUI episodes. In this pooled analysis of data from two double-blind, placebo-controlled trials, patients were randomized to placebo or fesoterodine 4 or 8 mg for 12 weeks and stratified into tertiles (>0- or =4) according to the number of UUI episodes/24 h as recorded in 3-day bladder diaries at baseline. The change in mean UUI episodes/24 h from baseline to end of study was assessed using analysis of covariance. In a post hoc analysis of data from two clinical trials, there were significant reductions from baseline in UUI episodes for fesoterodine 4 and 8 mg vs placebo in patients (n) with >0- or =4 (481) UUI episodes at baseline (all P or =4 UUI episodes at baseline, fesoterodine 8 mg gave significantly greater mean reductions (-1.92 and -4.17, respectively) vs fesoterodine 4 mg (-1.43 and -3.31) (P fesoterodine 4 mg, 19%; and 8 mg, 35%) and constipation (placebo, 2%; fesoterodine 4 mg, 5%; and 8 mg, 6%). Fesoterodine 4 and 8 mg significantly reduced UUI episodes vs placebo; this effect appeared to be greater with fesoterodine 8 mg in patients with > or =2 UUI episodes/24 h at baseline. Fesoterodine was well tolerated, although higher doses increased the incidence of adverse events. These findings might aid the clinical identification of patients with OAB who would most benefit from increasing the dose of fesoterodine from 4 to 8 mg.
