    2017-02-01

    Full Text Available A body of literature has noted that local food systems (LFSs may not involve active participation by individuals with lower incomes. This is, in part, a function of racial and class hegemony, as well as physical and financial accessibility of LFSs. LFS institutions, such as farmers’ markets, have been working to facilitate receipt of food assistance programs, such as the Supplemental Nutrition Assistance Program (SNAP. Charitable assistance programs, such as food banks, have also been actively working to engage in LFSs, for example, by making local foods available. However, little research has explored the role that receiving public or charitable assistance can play in influencing LFS participation. In this article, I utilize quantitative and qualitative data collected from across the state of Ohio to examine the relationship between receiving assistance and LFS participation for women, who remain predominately responsible for food provisioning in the U.S., including among those who participate in LFSs. Quantitative results suggest that receiving assistance can increase participation in LFSs. Qualitative data provides more nuanced information about the importance of food assistance for women who want to participate in LFSs, and suggest that it is essential that food cooperatives and farmers’ markets are equipped to receive food assistance programs, such as SNAP, in order for women with lower incomes to participate in LFSs.

    2004-01-01

    We report findings from a community-based two-city survey of homeless adults comparing the level of substance abuse treatment assigned to them using the ASAM Patient Placement Criteria with care actually received during the previous 12 months. Overall 531 adults were surveyed with 382 meeting DSM-IIIR criteria of being in need of treatment or having a demand for treatment. Of those with a treatment need, 1.5% met criteria for outpatient care, 40.3% intensive outpatient/partial hospitalization care, 29.8% medically monitored care and 28.8% managed care levels. In contrast, of those receiving treatment (50.5%, 162 persons), almost all care received by this cohort was either inpatient or residential based (83.6%). Unsheltered homeless persons and those without insurance were significantly more likely to report not receiving needed treatment. Lack of treatment availability or capacity, expense, and changing one's mind while on a wait list were the most commonly cited reasons for no treatment.

    When suffering becomes unbearable for patients they might request for euthanasia. To study which patients request for euthanasia and which requests actually resulted in euthanasia in relation with diagnosis, care setting at the end of life, and patient demographics. A cross-sectional study covering all Dutch health care settings. In 2005, of death certificates of deceased persons, a stratified sample was derived from the Netherlands central death registry. The attending physician received a written questionnaire (n = 6860; response 78%). If deaths were reported to have been nonsudden, the attending physician filled in a 4-page questionnaire on end-of-life decision-making. Data regarding the deceased person's age, sex, marital status, and cause of death were derived from the death certificate. Of patients whose death was nonsudden, 7% explicitly requested for euthanasia. In about two thirds, the request did not lead to euthanasia or physician-assisted suicide being performed, in 39% because the patient died before the request could be granted and in 38% because the physician thought the criteria for due care were not met. Factors positively associated with a patient requesting for euthanasia are (young) age, diagnosis (cancer, nervous system), place of death (home), and involvement of palliative teams and psychiatrist in care. Diagnosis and place of death are also associated with requests resulting in euthanasia. Only a minority of patients request euthanasia at the end of life and of these requests a majority is not granted. Careful decision-making is necessary in all requests for euthanasia.

    2014-12-01

    Full Text Available Introduction To investigate and highlight the effect of formaldehyde induced weight reduction in transurethral resection of prostate (TURP and radical robotically-assisted prostatectomy (RALP specimen as a result of standard chemical fixation. Materials and Methods 51 patients were recruited from January 2013 to June 2013 who either underwent a TURP (n=26 or RALP (n=25. Data was collected prospectively by the operating surgeon who measured the native, unfixed histology specimen directly after operation. The specimens were fixed in 10% Formaldehyde Solution BP and sent to the pathology laboratory where after sufficient fixation period was re-weighed. Results Overall mean age 64.78 years, TURP mean age 68.31 years RALP mean age 61.12years. We found that the overall prostatic specimen (n=51 weight loss after fixation was a mean of 11.20% (3.78 grams (p≤0.0001. Subgroup analysis of the native TURP chips mean weight was 16.15 grams and formalin treated mean weight was 14.00 grams (p≤0.0001. Therefore, TURP chips had a mean of 13.32 % (2.15 grams weight loss during chemical fixation. RALP subgroup unfixed specimen mean weight was 52.08 grams and formalin treated mean weight was 42.60 grams (p≤0.0001, a 19.32 % (9.48grams mean weight reduction. Conclusion It has not been known that prostatic chips and whole human radical prostatectomy specimen undergo a significant weight reduction. The practical significance of the accurate prostate weight in patient management may be limited, however, it is agreed that this should be recorded correctly, as data is potential interest for research purposes and vital for precise documentation.

    Cytotoxic chemotherapy dosages are traditionally calculated according to body surface area (BSA). No guidelines exist for chemotherapy dosing of acute myeloid leukemia (AML) patients at extremes of weight. We investigated the efficacy and safety of chemotherapy dosed according to BSA based on actual body weight (ABW) among under/normal weight, overweight, and obese AML patients. AML patients (excluding acute promyelocytic leukemia) treated with anthracycline and cytarabine-based remission induction chemotherapy from 2002 to 2009 at Cleveland Clinic were divided into three body mass index (BMI) groups: under/normal weight (BMI ≤ 24.9), overweight (BMI 25.0-29.9), and obese (BMI ≥ 30.0). Among 247 AML patients, 81 (33%) were under/normal weight, 81 (33%) were overweight, and 85 (34%) were obese. Complete remission (CR) rates were similar among these groups (69.1, 79.0, and 76.5%, respectively; P = 0.321), as was median survival (10.7, 16.7, and 14.2 months, respectively, P = 0.352) and 30-day mortality (3.7, 2.5, 7.1%, respectively, P = 0.331). There was no difference among groups in days to neutrophil or platelet recovery, hospitalization days for induction chemotherapy, and bacteremia. After adjustment for confounders (age, sex, BMI, white blood cells, cytogenetic risk, etiology, and bacteremia), overall survival was significantly shorter for normal weight compared to overweight (P = 0.006) and obese (0.038) patients. Response rates and adverse events were not significantly different among AML patients of all weight classes when induction chemotherapy was dosed according to ABW. Induction chemotherapy in these patients can be safely dosed using ABW. Copyright © 2013 Wiley Periodicals, Inc.

  14. Nearly One-Third Of Enrollees In California's Individual Market Missed Opportunities To Receive Financial Assistance.

    2017-01-01

    The Affordable Care Act includes financial assistance that reduces both premiums and cost-sharing amounts for lower-income Americans, to increase the affordability of health insurance coverage and care. To receive both types of assistance, enrollees must purchase a qualified health plan through a public insurance exchange, and those eligible for the cost-sharing reduction must purchase a silver-tier plan. We estimate that 31 percent of individual-market enrollees in California who were likely eligible for financial assistance purchased plans that were not silver tier or that were not sold on the state's exchange and thus missed opportunities to receive premium or cost-sharing assistance or both. Lower-income enrollees who chose plans not eligible for subsidies had two to three times higher odds of reporting difficulty paying premiums and out-of-pocket expenses during the year, compared to those who chose eligible plans. Regardless of how the structure of the individual market evolves in the coming years, efforts are likely needed to steer lower-income enrollees away from financially suboptimal plan choices.

    2016-01-01

    Full Text Available GNSS’s orbit determinations always rely on ground station or intersatellite links (ISL. In the emergency of satellite-to-ground links and ISL break-off, BeiDou navigation satellite system (BDS satellites cannot determine their orbits. In this paper, we propose to add a spaceborne annular beam antenna for receiving the global positioning system (GPS and global navigation satellite system (GLONASS signals; therefore, the BDS satellites may be capable of determining their orbits by GPS/GLONASS signals. Firstly, the spectrum selection, the power isolation, the range of Doppler frequency shift, and changing rate are taken into account for the feasibility. Specifically, the L2 band signals are chosen for receiving and processing in order to prevent the overlapping of the receiving and transmitting signals. Secondly, the minimum number of visible satellites (MNVS, carrier-to-noise ratio (C/N0, dilution of precision (GDOP, and geometric distance root-mean-square (gdrms are evaluated for acquiring the effective receiving antennas’ coverage ranges. Finally, the scheme of deploying 3 receiving antennas is proved to be optimal by analysis and simulations over the middle earth orbit (MEO, geostationary earth orbit (GEO, and the inclined geosynchronous satellite orbit (IGSO. The antennas’ structures and patterns are designed to draw a conclusion that installing GPS and GLONASS receivers on BDS satellites for emergent orbits determination is cost-effective.

    2015-11-01

    Physical illness and disability are common in individuals with substance use disorders, but little is known about the impact of physical disability status on substance use treatment outcomes. This study examined the main and interactive effects of physical disability payment status on substance use treatment. Participants (N = 1,013) were enrolled in one of six prior randomized clinical trials comparing contingency management (CM) to standard care; 79 (7.8%) participants reported receiving disability payments, CM improved all three primary substance use outcomes: treatment retention, percent negative samples and longest duration of abstinence. There was no significant main effect of physical disability payment status on treatment outcomes; however, a significant treatment condition by physical disability status interaction effect emerged in terms of retention in treatment and duration of abstinence achieved. Patients who were receiving physical disability payments responded particularly well to CM, and their time in treatment and durations of drug and alcohol abstinence increased even more markedly with CM than did that of their counterparts who were not receiving physical disability assistance. These findings suggest an objectively defined cohort of patients receiving substance use treatment who respond particularly well to CM.

    Transitioning into clinical practice can be stressful for the newly credentialed athletic trainer (AT). The support provided by mentors, peers, and athletic training faculty can increase confidence and enhance the transition. To create specific initiatives for a smoother transition, the perspectives of those in the secondary school setting are needed. To examine the transition to practice and mentorship of newly credentialed ATs providing medical care in the secondary school setting. Qualitative study. Secondary school setting. A total of 14 ATs (2 men, 12 women; age = 23.0 ± 2.0 years) participated in our study. They were employed in the secondary school setting through graduate assistantships, had been credentialed for less than 1 year, and had completed professional bachelor's degree programs. We completed 14 semistructured phone interviews. Interviews were recorded and transcribed verbatim. Two researchers independently following the stepwise progression of a general inductive approach completed the data analysis. Trustworthiness was established through multiple-analyst triangulation, peer review, and member checks. Two major themes emerged regarding the support received by our participants: past mentors and current networks of professionals. Past mentors provided autonomous learning opportunities during clinical education and then served as resources for guidance and advice. Current networks of professionals were defined by 2 subthemes: professional medical care providers and non-medical care providers within the secondary school setting (ie, athletic directors, coaches, parents). Former preceptors and faculty provided resources and support to help develop the newly credentialed AT's confidence and facilitate the transition. Preceptors should allow increased independence to help their students develop as clinicians. The creation of networks within the community, that is, the secondary school itself, is also critical in the transition as it provides the AT

    Yao Xiaocheng; Gong Zheng; Shi Yin

    2012-01-01

    This paper presents a programmable gain amplifier (PGA) circuit with a digitally assisted DC offset cancellation (DCOC) scheme for a direct conversion WLAN receiver.Implemented in a standard 0.13-μm CMOS process,the PGA occupies 0.39 mm2 die area and dissipates 6.5 mW power from a 1.2 V power supply.By using a single loop single digital-to-analog converter (DAC) mixed signal DC offset cancellation topology,the minimum DCOC settling time achieved is as short as 1.6 μs with the PGA gain ranging from-8 to 54 dB in a 2 dB step.The DCOC loop utilizes a segmented DAC structure to lower the design complexity without sacrificing accuracy and a digital control algorithm to dynamically set the DCOC loop to fast or normal response mode,making the PGA circuit in compliance with the targeted WLAN specifications.

    2008-01-01

    We examined health and social outcomes among children related to parental disposable income and receipt of social assistance. Swedish national registry data were used in a longitudinal design. We estimated relative risks and odds ratios for health and social outcomes in Poisson and logistic regressions among 1.2 million children between 1993 and 2002, and adjusted for factors that might affect the associations. Children in families receiving long-term social assistance showed considerably less satisfactory future prospects regarding health-related outcomes--all-cause mortality, suicide attempt, alcohol and drug misuse. Also, and to an even greater extent, the children experienced low educational attainment and social assistance in young adulthood compared with the rest of the population, and also in comparison with other low-income families. Low income was also associated with risk increases, but to a lesser extent. After taking into account the greater proportion of social-assistance recipients in low-income groups, attenuated risk increases remained only regarding future prospects of low education and social assistance. Regarding both low income and months receiving social assistance there was a gradient, at least in the age-adjusted analyses; there were greater risk increases among long-term recipients and among those with low incomes, and lower risk increases among short-term recipients and among those with high incomes. The results indicate that growing up in a family on long-term social assistance is a robust risk marker for compromised long-term development. A policy whereby children and parents receiving long-term assistance are offered access to evidence-based prevention programs in the areas of health, education and skills training appears to be important.

    2000-05-01

    This paper draws on interviews with users of direct payments and focus group discussions with the personal assistants (PAs) who assist them with personal and daily living activities. It discusses the benefits and the drawbacks of directly employing such assistance, from the perspectives of both the purchasers and the providers of these services. The paper shows that direct payments can enable disabled people to purchase a much wider range of flexible help, better continuity, greater control and an enhanced quality of life, compared with conventional services. PAs also valued the trust and close relationships they developed with their employers. However, these benefits were much less marked when direct payment users recruited and employed personal assistants through care agencies. On the other hand, both direct payment users and PAs also sometimes experienced difficulties in managing the relationships between them. Some of these problems could be alleviated by changes in the support provided by direct payment schemes themselves; other difficulties were more intractable and arose from the nature of the work and the close relationships which it entailed. The paper recommends a number of measures which could reduce the risks and vulnerability of both disabled direct payment users and personal assistants, without reducing the enhanced quality of life which direct payments can confer.

    In this work, a novel signal processing method is proposed to assist the Receiver Autonomous Integrity Monitoring (RAIM) module used in a receiver of Global Navigation Satellite Systems (GNSS) to improve the integrity of the estimated position. The proposed technique represents an evolution of the Multipath Distance Detector (MPDD), thanks to the introduction of a Signal Quality Index (SQI), which is both a metric able to evaluate the goodness of the signal, and a parameter used to improve the performance of the RAIM modules. Simulation results show the effectiveness of the proposed method.

    2016-12-02

    Advanced heart failure (HF) is sometimes complicated with brain impairment because of a microthrombosis caused by decreased left ventricular contraction or reduced brain circulation. Some patients may recover after left ventricular assist device (LVAD) implantation. However, little is known about the perioperative therapeutic strategy in patients suffering from such complications, particularly from a cardiac rehabilitation viewpoint. We report on a 58-year-old male patient with a previous history of poliomyelitis and a light paralysis in the left upper extremity, who suffered left hemiplegia with no evidence of stroke after hemodynamic deterioration. The combination therapy of perioperative cardiac rehabilitation and LVAD therapy improved his left hemiplegia as well as activities of daily living, and the patient was discharged on foot on postoperative day 72 after briefing the family on LVAD home management. Early initiation of cardiac rehabilitation before LVAD implantation may be a key for the smooth discharge and resocialization of patients suffering from brain impairment complicated with advanced HF.

    2015-01-01

    Women enrolled in Florida's Temporary Assistance for Needy Families (TANF) program experience high rates of chronic health problems and often lack a usual source of care. Thus, in this study, we aimed to identify variables related to being in a usual source of care at time of study enrollment and determine whether a public health nursing case management intervention affected the obtainment of a usual source of care. To achieve these aims, we conducted a secondary analysis of a randomized controlled trial of a public health nursing case management intervention, which included women with chronic health conditions enrolled in TANF (n = 432). Results indicated 35% of the women did not identify a usual source of care at time of study enrollment, and the public health nursing intervention was effective in helping women obtain a usual source of care (OR = 2.5, 95% CI 1.004-6.491). Thus, a public health nursing case management intervention is an effective way to connect TANF participants to a usual source of care, which may lead to improved health outcomes in this vulnerable population of women.

    Full Text Available The implementation of efficient baseband receivers characterized by affordable computational load is a crucial point in the development of transmission systems exploiting diversity in different domains. This would be a crucial point in the future development of 4G systems, where space, time, and frequency diversity will be combined together in order to increase system throughput. In this framework, a linear multiuser detector for MC-CDMA systems with Alamouti's Space-Time Block Coding (STBC, which is inspired by the concept of Minimum Conditional Bit Error Rate (MCBER, is proposed. The MCBER combiner has been implemented in adaptive way by using Least-Mean-Square (LMS optimization. The estimation of Channel State Information (CSI, necessary to make practically feasible the MCBER detection, is aided by a Genetic Algorithm (GA. The obtained receiver scheme is near-optimal, as both LMS-based MCBER and GA-assisted channel estimation perform closely to optimum in fulfilling their respective tasks. Simulation results evidenced that the proposed receiver always outperforms state-of-the-art receiver schemes based on EGC and MMSE criterion exploiting the same degree of channel knowledge.

    Background Video-assisted thoracic surgery (VATS) and thoracotomy are standard treatment methods for early lung cancer. We compared their effects on the long-term recovery of pulmonary function in patients with stage I non-small cell lung cancer (NSCLC). Methods We retrospectively reviewed 203 patients with early NSCLC who underwent VATS or thoracotomy at Seoul University Hospital from January 2005 to December 2010. Two matched groups (VATS and thoracotomy) each consisting of 60 patients were created via propensity score matching according to TNM stage, age, sex, smoking history, lung disease history, and preoperative pulmonary function. Results There were no significant differences in the recovery of forced expiratory volume in 1 second, the forced vital capacity (FVC), or the peak flow rate (PFR), presented as the postoperative value/predicted value, between the VATS and thoracotomy groups during the 12-month follow-up period. The standardized functional loss ratio [(measured postoperative value – predicted postoperative value)/(predicted postoperative value × 100)] did not differ between the two groups at 6 and 12 months. In an intragroup analysis, the postoperative FVC in the thoracotomy group remained below predicted postoperative value during the follow-up period and did not reach the predicted postoperative FVC (6 months/12 months: –6.58%/–2.43%). The analgesic requirements and pain procedures were similar in the VATS and thoracotomy groups during the 12-month follow-up period. Conclusions There were no significant differences in pulmonary function recovery during the late postoperative period in NSCLC patients receiving VATS versus thoracotomy. We suggest that the volume of the resected lung and preoperative lung function are the main determinants of late recovery, rather than postoperative pain. PMID:26904225

    Many end-stage heart failure patients are not eligible to undergo heart transplantation due to organ shortage, and even those under consideration for transplantation might suffer long waiting periods. A better understanding of the hemodynamic impact of left ventricular assist devices (LVAD) on the cardiovascular system is therefore of great interest. Computational fluid dynamics (CFD) simulations give the opportunity to study the hemodynamics in this patient population using clinical imaging data such as computed tomographic angiography. This article reviews a recent study series involving patients with pulsatile and constant-flow LVAD devices in which CFD simulations were used to qualitatively and quantitatively assess blood flow dynamics in the thoracic aorta, demonstrating its potential to enhance the information available from medical imaging.

  5. MEDECOR--a medical decorporation tool to assist first responders, receivers, and medical reach-back personnel in triage, treatment, and risk assessment after internalization of radionuclides.

    Waller, Ed; Wilkinson, Diana

    2010-10-01

    After a radiological dispersal device (RDD) event, it is possible for radionuclides to enter the human body through inhalation, ingestion, and skin and wound absorption. From a health physics perspective, it is important to know the magnitude of the intake to perform dosimetric assessments. From a medical perspective, removal of radionuclides leading to dose aversion (hence risk reduction) is of high importance. The efficacy of medical decorporation strategies is extremely dependent upon the time of treatment delivery after intake. The "golden hour," or more realistically 3-4 h, is optimal when attempting to increase removal of radionuclides from extracellular fluids prior to cellular incorporation. To assist medical first response personnel in making timely decisions regarding appropriate treatment delivery modes, it is desirable to have a software tool that compiles existing radionuclide decorporation therapy data and allows a user to perform simple diagnosis leading to optimized decorporation treatment strategies. In its most simple application, the software is a large database of radionuclide decorporation strategies and treatments. The software can also be used in clinical interactive mode, in which the user inputs the radionuclide, estimated activity, route of intake and time since exposure. The software makes suggestions as to the urgency of treatment (i.e., triage) and the suggested therapy. Current developments include risk assessment which impacts the potential risk of delivered therapy and resource allocation of therapeutic agents. The software, developed for the Canadian Department of National Defence (DND), is titled MEDECOR (MEdical DECORporation). The MEDECOR tool was designed for use on both personal digital assistant and laptop computer environments. The tool was designed using HTML/Jscript, to allow for ease of portability amongst different computing platforms. This paper presents the features of MEDECOR, results of testing at a major NATO

  6. Prioritizing stream types according to their potential risk to receive crop plant material--A GIS-based procedure to assist in the risk assessment of genetically modified crops and systemic insecticide residues.

    Crop plant residues may enter aquatic ecosystems via wind deposition or surface runoff. In the case of genetically modified crops or crops treated with systemic pesticides, these materials may contain insecticidal Bt toxins or pesticides that potentially affect aquatic life. However, the particular exposure pattern of aquatic ecosystems (i.e., via plant material) is not properly reflected in current risk assessment schemes, which primarily focus on waterborne toxicity and not on plant material as the route of uptake. To assist in risk assessment, the present study proposes a prioritization procedure of stream types based on the freshwater network and crop-specific cultivation data using maize in Germany as a model system. To identify stream types with a high probability of receiving crop materials, we developed a formalized, criteria-based and thus transparent procedure that considers the exposure-related parameters, ecological status--an estimate of the diversity and potential vulnerability of local communities towards anthropogenic stress--and availability of uncontaminated reference sections. By applying the procedure to maize, ten stream types out of 38 are expected to be the most relevant if the ecological effects from plant-incorporated pesticides need to be evaluated. This information is an important first step to identifying habitats within these stream types with a high probability of receiving crop plant material at a more local scale, including accumulation areas. Moreover, the prioritization procedure developed in the present study may support the selection of aquatic species for ecotoxicological testing based on their probability of occurrence in stream types having a higher chance of exposure. Finally, this procedure can be adapted to any geographical region or crop of interest and is, therefore, a valuable tool for a site-specific risk assessment of crop plants carrying systemic pesticides or novel proteins, such as insecticidal Bt toxins, expressed

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

    2014-05-01

    The most actual goals of geoethics have been formulated as results of the International Conference on Geoethics (October 2013) held at the geoethics birth-place Pribram (Czech Republic): In the sphere of education and public enlightenment an appropriate needed minimum know how of Earth sciences should be intensively promoted together with cultivating ethical way of thinking and acting for the sustainable well-being of the society. The actual activities of the Intergovernmental Panel of Climate Changes are not sustainable with the existing knowledge of the Earth sciences (as presented in the results of the 33rd and 34th International Geological Congresses). This knowledge should be incorporated into any further work of the IPCC. In the sphere of legislation in a large international co-operation following steps are needed: - to re-formulate the term of a "false alarm" and its legal consequences, - to demand very consequently the needed evaluation of existing risks, - to solve problems of rights of individuals and minorities in cases of the optimum use of mineral resources and of the optimum protection of the local population against emergency dangers and disasters; common good (well-being) must be considered as the priority when solving ethical dilemmas. The precaution principle should be applied in any decision making process. Earth scientists presenting their expert opinions are not exempted from civil, administrative or even criminal liabilities. Details must be established by national law and jurisprudence. The well known case of the L'Aquila earthquake (2009) should serve as a serious warning because of the proven misuse of geoethics for protecting top Italian seismologists responsible and sentenced for their inadequate superficial behaviour causing lot of human victims. Another recent scandal with the Himalayan fossil fraud will be also documented. A support is needed for any effort to analyze and to disclose the problems of the deformation of the contemporary

    Indicators of central bank independence (CBI) based on the interpretation central bank laws in place may not capture the actual independence of the central bank. This paper develops an indicator of actual independence of the Bank Indonesia (BI), the central bank of Indonesia, for the period 1953-2008 and compares it with a new legal CBI indicator based on Cukierman (1992). The indicator of actual independence captures institutional and economic factors that affect CBI. We find that before 199...

  4. [Actual questions about the prevention of venous thromboembolism in cancer patients receiving chemotherapy].

    Science.gov (United States)

    Losonczy, Hajna; Nagy, Ágnes; Tar, Attila

    2016-02-07

    Cancer patients have a 2-7 fold increased risk of venous thromboembolism compared with the general population and, since 1990, this is associated with significant morbidity and mortality. This review summarizes the current knowledge on venous thromboembolism and cancer. Notably, the risk of venous thromboembolism varies depending on the type and stage of cancer. For instance, pancreatic and brain cancer patients have a higher risk of venous thromboembolism than breast and prostate cancer patients. Moreover, patients with metastatic disease have a higher risk than those with localized tumors. Tumor-derived procoagulant factors, cytokines and growth factors may directly and indirectly enhance venous thromboembolism. Chemotherapy produces ~6,5 fold increase in venous thromboembolism incidence in cancer patients compared to the general population. Prevention of this complication is challenging. The authors review the development of guidelines concerning venous thromboembolism prevention in hospitalized and also in ambulatory cancer patients treated with chemotherapy. Current guidelines recommend the use of low-molecular-weight heparin. Understanding the underlying mechanisms may allow the development of new therapies to safely prevent venous thromboembolism in cancer patients.

    2014-01-01

    Proper modelling of astronomical receivers is vital: it describes the systematic errors in the raw data, guides the receiver design process, and assists data calibration. In this paper we describe a method of analytically modelling the full signal and noise behaviour of arbitrarily complex radio receivers. We use electrical scattering matrices to describe the signal behaviour of individual components in the receiver, and noise correlation matrices to describe their noise behaviour. These are combined to produce the full receiver model. We apply this approach to a specified receiver architecture: a hybrid of a continous comparison radiometer and correlation polarimeter designed for the C-Band All-Sky Survey. We produce analytic descriptions of the receiver Mueller matrix and noise temperature, and discuss how imperfections in crucial components affect the raw data. Many of the conclusions drawn are generally applicable to correlation polarimeters and continuous comparison radiometers.

    Foxman, P

    1976-02-01

    This study was designed to test the hypothesis, implicit in several areas of previous research, that high tolerance for ambiguity is a cognitive style which reflects high levels of underlying psychological health. Using Self-Actualization scores on the Tennessee Self Concept Scale, 36 adult subjects were defined as relatively high or low in self-actualization with equal numbers of males and females in each group. All subjects then performed individually on the Rorschach test and the Rorschach protocols were rated reliably for degree of tolerance for ambiguity. It was found that regardless of sex the high self-actualization group exhibited a significantly higher level of tolerance for ambiguity than the low self-actualization group. The finding was interpreted as confirmation of the study's hypothesis.

  14. Low complexity MIMO receivers

    CERN Document Server

    Bai, Lin; Yu, Quan

    2014-01-01

    Multiple-input multiple-output (MIMO) systems can increase the spectral efficiency in wireless communications. However, the interference becomes the major drawback that leads to high computational complexity at both transmitter and receiver. In particular, the complexity of MIMO receivers can be prohibitively high. As an efficient mathematical tool to devise low complexity approaches that mitigate the interference in MIMO systems, lattice reduction (LR) has been widely studied and employed over the last decade. The co-authors of this book are world's leading experts on MIMO receivers, and here they share the key findings of their research over years. They detail a range of key techniques for receiver design as multiple transmitted and received signals are available. The authors first introduce the principle of signal detection and the LR in mathematical aspects. They then move on to discuss the use of LR in low complexity MIMO receiver design with respect to different aspects, including uncoded MIMO detection...

  20. Improving child support enforcement for children receiving SSI.

    Science.gov (United States)

    Wilschke, S

    Less than half of all children who receive Supplemental Security Income (SSI) benefits and live in a single-parent home receive child support services. Although filing for child support is a condition of eligibility for income assistance programs such as Temporary Assistance for Needy Families (TANF), it is not a condition of eligibility for SSI benefits. Requiring single custodial parents applying for SSI on behalf of their children to pursue child support payments might result in more children on SSI receiving child support, and since the Social Security Administration (SSA) excludes one-third of child support when determining benefit amounts, increased receipt of child support would enhance the financial well-being of SSI children. Improving access to data on child support would enhance the integrity of the SSI program by reducing overpayments to children receiving child support. This article looks at the child support provisions in SSI and other means-tested programs and discusses policy options for improving receipt of child support and access to related data. Requiring cooperation with child support enforcement agencies would be consistent with the philosophy that the SSI program should serve as a program of last resort. Whenever possible, both parents should take primary responsibility for their children. While such a requirement has the potential to improve the financial status of children receiving SSI, factors such as their low-income status and their involvement with the TANF program raise questions about how much those children will actually benefit from such a requirement. Even if many additional children do not receive child support, the requirement demonstrates SSA's dedication to the stewardship of the SSI program. However, if custodial parents fail to comply with the requirement, children may be worse off as a result of the requirement. SSA should carefully pursue a requirement to induce cooperation while protecting children to the greatest extent

Definir el valor actual de la Universidad lleva a una discusión que se resuelve en la búsqueda de lo que ella ha de significar para la sociedad actual. El valor que tradicionalmente se le atribuye —transmisión de conocimientos e investigación— es ya inoperante dado que sus funciones centrales se realizan con éxito fuera de Ella. Por eso se postula el valor de la Universidad en la incorporación de la imaginación creativa para formar a los estudiantes en la conciencia y la responsabilidad de crear su futuro personal y el de la sociedad. Dicho valor no se limita al pasado ni al presente; asume a éstos como lo que da forma al futuro.

    This book demonstrates how to design a wideband receiver operating in current mode, in which the noise and non-linearity are reduced, implemented in a low cost single chip, using standard CMOS technology.  The authors present a solution to remove the transimpedance amplifier (TIA) block and connect directly the mixer’s output to a passive second-order continuous-time Σ∆ analog to digital converter (ADC), which operates in current-mode. These techniques enable the reduction of area, power consumption, and cost in modern CMOS receivers.

  10. Housing Assistance

    Full Text Available In Australia, an increasing number of households face problems of access to suitable housing in the private market. In response, the Federal and State Governments share responsibility for providing housing assistance to these, mainly low-income, households. A broad range of policy instruments are used to provide and maintain housing assistance across all housing tenures, for example, assisting entry into homeownership, providing affordability assistance in the private rental market, and the provision of socially owned and managed housing options. Underlying each of these interventions is the premise that secure, affordable, and appropriate housing provides not only shelter but also a number of nonshelter benefits to individuals and their households. Although the nonshelter outcomes of housing are well acknowledged in Australia, the understanding of the nonshelter outcomes of housing assistance is less clear. This paper explores nonshelter outcomes of three of the major forms of housing assistance provided by Australian governments—low-income mortgage assistance, social housing, and private rent assistance. It is based upon analysis of a survey of 1,353 low-income recipients of housing assistance, and specifically measures the formulation of health and well-being, financial stress, and housing satisfaction outcomes across these three assistance types. We find clear evidence that health, finance, and housing satisfaction outcomes are associated with quite different factors for individuals in these three major housing assistance types.

    Marcin, Martin; Abramovici, Alexander

    2008-01-01

    The software of a commercially available digital radio receiver has been modified to make the receiver function as a two-channel low-noise phase meter. This phase meter is a prototype in the continuing development of a phase meter for a system in which radiofrequency (RF) signals in the two channels would be outputs of a spaceborne heterodyne laser interferometer for detecting gravitational waves. The frequencies of the signals could include a common Doppler-shift component of as much as 15 MHz. The phase meter is required to measure the relative phases of the signals in the two channels at a sampling rate of 10 Hz at a root power spectral density digital receiver. The input RF signal is first fed to the input terminal of an analog-to-digital converter (ADC). To prevent aliasing errors in the ADC, the sampling rate must be at least twice the input signal frequency. The sampling rate of the ADC is governed by a sampling clock, which also drives a digital local oscillator (DLO), which is a direct digital frequency synthesizer. The DLO produces samples of sine and cosine signals at a programmed tuning frequency. The sine and cosine samples are mixed with (that is, multiplied by) the samples from the ADC, then low-pass filtered to obtain in-phase (I) and quadrature (Q) signal components. A digital signal processor (DSP) computes the ratio between the Q and I components, computes the phase of the RF signal (relative to that of the DLO signal) as the arctangent of this ratio, and then averages successive such phase values over a time interval specified by the user.

  10. La estructura resistente en la arquitectura actual

    Directory of Open Access Journals (Sweden)

    Manterola Armisén, J.

    1998-10-01

    Full Text Available A significant portion in nowadays architecture uses the resistant structures as a fundamental element conveying expression to a building. Resistant structures usually designed, calculated and built by engineers are in some occasions -those that draw our attention now- designed by architects who stress the plastic dimension. Sometimes architects have just tried to soften the elementality of the resistance per se. To abandon the quantitative element to get centered in the qualitative and expressive is a leitmotiv in the architectural proceedings that has been brilliantly fruitful in many an occasion -notice Frei Otto's work among others- but that, in other cases, damages the understanding of the resistant aspect by excessively priorizing the structure appearance upon the structure itself. This article makes a critical account of a series of structures in recent buildings, classified by resistance typologies, flat or spatial trusses, frames, domes, hanging and distensible roofs, tensigrity structures, etc., preceded by a retrospect on how resistance has been traditionally understood.

    Una parte de la arquitectura actual se caracteriza por utilizar la estructura resistente como el elemento expresivo fundamental del edificio. Las estructuras resistentes, diseñadas, calculadas y construidas hasta ahora por ingenieros, han pasado, en algunas ocasiones -las que aquí nos interesan-, a ser diseñadas por arquitectos que acentúan su dimensión plástica. En otras ocasiones los arquitectos se han reducido a dulcificar la elementalidad de lo resistente en cuanto tal. El abandono de lo cuantitativo, para centrarse en lo cualitativo y expresivo, es el "leit motiv" de ese proceder arquitectónico que ha dado frutos muy brillantes en bastantes ocasiones, no hay sino que ver el trabajo de Frei Otto y otros, pero que, en otros casos, perjudican el entendimiento de lo resistente al primar, excesivamente, la apariencia de estructura sobre lo que es la

  13. Nanomaterials environmental risks and recycling: Actual issues

    Directory of Open Access Journals (Sweden)

    Živković Dragana

    2014-01-01

    Full Text Available Nanotechnologies are being spoken of as the driving force behind a new industrial revolution. Nanoscience has matured significantly during the last decade as it has transitioned from bench top science to applied technology. Presently, nanomaterials are used in a wide variety of commercial products such as electronic components, sports equipment, sun creams and biomedical applications. The size of nanoparticles allows them to interact strongly with biological structures, so they present potential human and environmental health risk. Nanometer size presents also a problem for separation, recovery, and reuse of the particulate matter. Therefore, industrial-scale manufacturing and use of nanomaterials could have strong impact on human health and the environment or the problematic of nanomaterials recycling. The catch-all term ''nanotechnology' is not sufficiently precise for risk governance and risk management purposes. The estimation of possible risks depends on a consideration of the life cycle of the material being produced, which involves understanding the processes and materials used in manufacture, the likely interactions between the product and individuals or the environment during its manufacture and useful life, and the methods used in its eventual disposal. From a risk-control point of view it will be necessary to systematically identify those critical issues, which should be looked at in more detail. Brief review of actual trends in nanomaterials environmental risks and recycling is given in this paper.

  19. Consequences of Predicted or Actual Asteroid Impacts

    Science.gov (United States)

    Chapman, C. R.

    2003-12-01

    Earth impact by an asteroid could have enormous physical and environmental consequences. Impactors larger than 2 km diameter could be so destructive as to threaten civilization. Since such events greatly exceed any other natural or man-made catastrophe, much extrapolation is necessary just to understand environmental implications (e.g. sudden global cooling, tsunami magnitude, toxic effects). Responses of vital elements of the ecosystem (e.g. agriculture) and of human society to such an impact are conjectural. For instance, response to the Blackout of 2003 was restrained, but response to 9/11 terrorism was arguably exaggerated and dysfunctional; would society be fragile or robust in the face of global catastrophe? Even small impacts, or predictions of impacts (accurate or faulty), could generate disproportionate responses, especially if news media reports are hyped or inaccurate or if responsible entities (e.g. military organizations in regions of conflict) are inadequately aware of the phenomenology of small impacts. Asteroid impact is the one geophysical hazard of high potential consequence with which we, fortunately, have essentially no historical experience. It is thus important that decision makers familiarize themselves with the hazard and that society (perhaps using a formal procedure, like a National Academy of Sciences study) evaluate the priority of addressing the hazard by (a) further telescopic searches for dangerous but still-undiscovered asteroids and (b) development of mitigation strategies (including deflection of an oncoming asteroid and on- Earth civil defense). I exemplify these issues by discussing several representative cases that span the range of parameters. Many of the specific physical consequences of impact involve effects like those of other geophysical disasters (flood, fire, earthquake, etc.), but the psychological and sociological aspects of predicted and actual impacts are distinctive. Standard economic cost/benefit analyses may not

  20. Assisted distillation of quantum coherence

    CERN Document Server

    Chitambar, E; Rana, S; Bera, M N; Adesso, G; Lewenstein, M

    2015-01-01

    We introduce and study the task of assisted coherence distillation. This task arises naturally in bipartite systems where both parties work together to generate the maximal possible coherence on one of the subsystems. Only incoherent operations are allowed on the target system while general local quantum operations are permitted on the other, an operational paradigm that we call local quantum-incoherent operations and classical communication (LQICC). We show that the asymptotic rate of assisted coherence distillation for pure states is equal to the coherence of assistance, a direct analog of the entanglement of assistance, whose properties we characterize. Our findings imply a novel interpretation of the von Neumann entropy: it quantifies the maximum amount of extra quantum coherence a system can gain when receiving assistance from a collaborative party. Our results are generalized to coherence localization in a multipartite setting and possible applications are discussed.

    2016-06-20

    For outdoor and global navigation satellite system (GNSS) challenged scenarios, collaborative positioning algorithms are proposed to fuse information from GNSS satellites and terrestrial wireless systems. This paper derives the Cramer-Rao lower bound (CRLB) and algorithms for the angle-of-arrival (AOA)-assisted GNSS collaborative positioning. Based on the CRLB model and collaborative positioning algorithms, theoretical analysis are performed to specify the effects of various factors on the accuracy of collaborative positioning, including the number of users, their distribution and AOA measurements accuracy. Besides, the influences of the relative location of the collaborative users are also discussed in order to choose appropriate neighboring users, which is in favor of reducing computational complexity. Simulations and actual experiment are carried out with several GNSS receivers in different scenarios, and the results are consistent with theoretical analysis.

    The following is a synopsis of the major achievements attributed to the operation of the Weatherization Assistance Program Technical Assistance Center (WAPTAC) by the National Association for State Community Services Programs (NASCSP). During the past five years, the WAPTAC has developed into the premier source for information related to operating the Weatherization Assistance Program (WAP) at the state and local levels. The services provide through WAPTAC include both virtual technical support as well as hands-on training and instruction in classroom and in the field. The WAPTAC achieved several important milestones during its operation including the establishment of a national Weatherization Day now celebrated in most states, the implementation of a comprehensive Public Information Campaign (PIC) to raise the awareness of the Program among policy makers and the public, the training of more than 150 new state managers and staff as they assume their duties in state offices around the country, and the creation and support of a major virtual information source on the Internet being accessed by thousands of staff each month. The Weatherization Assistance Program Technical Assistance Center serves the Department of Energy's (DOE) Office of Weatherization and Intergovernmental Program as a valuable training and technical assistance resource for the network of 54 direct state grantees (50 states, District of Columbia and three Native American tribes) and the network of 900 local subgrantees (comprised of community action agencies, units of local government, and other non-profit organizations). The services provided through WAPTAC focus on standardizing and improving the daily management of the WAP. Staff continually identify policies changes and best practices to help the network improve its effectiveness and enhance the benefits of the Program for the customers who receive service and the federal and private investors. The operations of WAPTAC are separated into

    2017-02-01

    This article identifies concepts, trends, and policy gaps in the availability and service delivery of assistive technology utilized by older adults in disasters, as well as implications for emergency management planning and shelter administration. Definitions of types of assistive technology, as well as views of older adults using technology as at-risk individuals for emergency management service provision, are provided. An overview of peer-reviewed articles and gray literature is conducted, focusing on publications from 2001 to the present in the United States. Analytical frameworks used by emergency management organizations as well as regulations such as the Americans with Disabilities Act and recent court decisions on emergency shelter accessibility in disasters are reviewed. Research on the use of assistive technology by older adults during disasters is a neglected issue. The current and potential benefits of defining standards for provision and use of assistive technology for older adults during disasters has received limited recognition in emergency management planning. Older adults with disabilities utilize assistive technology to maintain their independence and dignity, and communities as well as emergency services managers need to become more aware of the needs and preferences of these older adults in their planning processes and drills as well as in service delivery during actual events.

    Full Text Available The main characteristics of the land and the supporting rock are given, and the pattern of present performance of Chicago's deep foundations is briefly described. This city probably has some of the highest skyscrapers in the world with deep foundations resting on rock, and possibly as well, the highest building with foundations resting on soil. The construction of piles of large diameter, resting on rock and concreted dry, as prescribed by the City Code, is the weak point which sometimes makes it necessary to insert a permanent lining tube deep into the rock in order to obtain the required leaktightness, or to pump out significant quantities of water from the bottom of the excavations. The latter can cause the dragging away of earth from adjacent foundations resting on soil at a higher level, as with the drift of the phreatic level, with the consequent risk of producing appreciable subsidence, and even undermining. To overcome this problem we carried out for the first time in Chicago, a pre-sealing, by means of chemical injections, of the supporting rock of the periphery piles of some deep foundations, by drilling into the centre of each pile, which has also been useful as a means of examining the subsoil before proceeding to the perforation of each pile. This operation was carried out on the large diameter piles of the foundations of the Northern Trust Bank skyscraper, at present under construction, with very satisfactory results. The method of pre-sealing the rock used and the results obtained are described.Se presentan las características principales del terreno y de la roca de apoyo y se describe someramente la forma de ejecución actual de las cimentaciones profundas de Chicago.

    Full Text Available Previous research showed that instructions about CS-US pairings can lead to fear of the CS even when the pairings are never presented. In the present study, we examined whether the experience of CS-US pairings adds to the effect of instructions by comparing instructed conditioning with and without actual CS-US pairings in a within-subject design. Thirty-two participants saw three fractals as CSs (CS(+1, CS(+2, CS(- and received electric shocks as USs. Before the start of a so-called training phase, participants were instructed that both CS(+1 and CS(+2 would be followed by the US, but only CS(+1 was actually paired with the US. The absence of the US after CS(+2 was explained in such a way that participants would not doubt the instructions about the CS(+2-US relation. After the training phase, a test phase was carried out. In this phase, participants expected the US after both CS(+s but none of the CS(+s was actually paired with the US. During test, self-reported fear was initially higher for CS(+1 than for CS(+2, which indicates that the experience of actual CS-US pairings adds to instructions about these pairings. On the other hand, the CS(+s elicited similar skin conductance responses and US expectancies. Theoretical and clinical implications are discussed.

The purpose of this paper is to define the actual situation of family business on the market, particularly focused on qualities of family business and its strengths or weaknesses. The object of research is the family business as an economical phenomenon. The study includes two subjects: firstly, to find out a specification of the family business, to analyze family ties within the business in accordance with the laws of the Czech Republic or to find out the current economic situation in family business and, secondly, to identify the features of family business as well as the difficulties faced thereby, lying in a base of two main components, namely the family system and the same of entrepreneurship. Methodology/methods: The article was prepared on the basis of general theoretical scientific methods, particularly on those of analysis, synthesis, analogy, comparison, generalization and deduction, or the method of expert estimates. For the analysis of the actual situation in big Czech family business enterprises, it was decided to use the secondary data of a top research-journal for this area, namely the Forbes.cz. In accordance with one of the paper goals, a SWOT analysis was applied to find out the basic strengths and weaknesses of family business. It was decided to verify the received information by interviewing several representatives of the family business in the Czech Republic. Scientific aim: The aim of scientific research is to improve the understanding of family business from the perspective of difficulties faced by family business and its economic perspectives. Findings: The results of this study have allowed the finding of a definition for the family business based on family ties and the laws of the Czech Republic. Another finding is that family business as a motor of the Czech economy has a real potencial for its development and it is able to enhance the Czech economy competitiveness on the world market. In

    Some of the reflected beam radiation from a heliostat field bypasses the receiver surface. The spillage factor which is a measure of how much of reflected beam radiation actually intercepted by the receiver surface, is calculated and plotted for easy access. The variation of the spillage with tower height, external cylindrical receiver size, dimensionless radial distance from the tower is computed and plotted. The value of the rated MW energy absorbed by an external cylindrical receiver, is investigated, and its relations to the tower height, the site location and the field radius are given. The effect of changing the radial spacing on the rated MW and the total number of heliostats in the field is also computed and depicted. The developed set of charts for the spillage factor are believed to be very useful for solar central receiver system design. (author) 7 figs., 21 refs.

    Social isolation has got to be one of the greatest losses in schizophrenia. For many authors, people with schizophrenia can have no friends, no spouse, and sometimes no family. Two thirds of patients with schizophrenia return to their parents' house after discharge from a hospital for the first psychosi episode. Family members generally receive very little education as to what they can expect. They may not know the importance of medication compliance. Family members are the primary victims of violence from psychotic individuals, usually their own son or daughter, and most families cannot believe their own son or daughter would be capable of such a thing. Although families are usually the main care givers at the beginning of schizophrenia they often find their experience very frustrating for a number of reasons, and relationships suffer. Family education and support have been shown to improve outcomes considerably and family education is the second strongest factor in relapse prevention. Without education and good relapse prevention families often burst out. Most of the homeless mentally ill in downtown city cores have lost their family relationships. It is not a reflection on their families so much as the lack of adequate treatment and support. The families tried and tried and lost their ill relative. A patient writes: "My father lives just outside of Monaco. My mother developed Alzheimer's a couple of years ago or so and with a series of mild strokes died recently. I haven't seen either of them very much in the last fifteen years. I have a sister, Nicole, who also lives in Paris. I lost those relationships to some degree over the years. I am rebuilding them now. Enter the professional friend, the case manager, usually in cases where the individual is quite disabled by schizophrenia and/or at considerable risk of relapse, and usually when the individual has lost their family relationships to some degree. I had a case manager for several years and always looked

  2. Social effects of migration in receiving countries.

    1989-06-01

    This paper examines the impact of post-1945 migration into Western, Middle, and Northern Europe from Southern Europe, Turkey, and Northern Africa, and migration to the traditional immigration countries by Asian and Latin American immigrants, on the social structures of receiving countries. Between 1955 and 1974, 1) traditional migration to the US and Australia became less important for European countries while traditional receiving countries accepted many immigrants from developing countries; and 2) rapid economic revival in Western and Northern Europe caused a considerable labor shortage which was filled by migrant workers especially from Southern Europe, Turkey, and Northern Africa, who stayed only until they reached their economic goals. Since 1974, job vacancies have declined and unemployment has soared. This employment crisis caused some migrants 1) to return to their countries of origin, 2) to bring the rest of their families to the receiving country, or 3) to lengthen their stay considerably. The number of refugees has also significantly increased since the mid-970s, as has the number of illegal migrants. After the mid-1970s, Europe began to experience integration problems. The different aspects of the impact of migration on social structures include 1) improvement of the housing situation for foreigners, 2) teaching migrants the language of the receiving country, 3) solving the unemployment problem of unskilled migrants, 4) improvement of educational and vocational qualifications of 2nd generation migrants, 5) development of programs to help unemployed wives of migrants to learn the language and meet indigenous women, 6) encouraging migrants to maintain their cultural identity and assisting them with reintegration if they return to their original country, 7) coping with the problems of refugees, and 8) solving the problems of illegal migration. Almost all receiving countries now severely restrict further immigration. [Those policies should result in

    Amyotrophic lateral sclerosis (ALS) is a disease that causes progressive paralysis leading to respiratory failure. Patients with ALS may consider physician-assisted suicide. However, it is not known how many patients, if given the option, would actually decide to end their lives by physician-assisted suicide or euthanasia nor at what stage of the disease they would choose to do so. We identified physicians of 279 patients in the Netherlands with a diagnosis of ALS who died between 1994 and 1999. Physicians were asked to fill out a validated questionnaire about the end-of-life decisions that were made. Of 241 eligible physicians, 203 returned the questionnaire (84 percent). Of the 203 patients, 35 (17 percent) chose euthanasia and died that way. An additional six patients (3 percent) died as a result of physician-assisted suicide. Patients to whom religion was important were less likely to have died as a result of euthanasia or physician-assisted suicide. The choice of euthanasia or physician-assisted suicide was not associated with any particular characteristics of the disease or of the patient's care, nor was it associated with income or educational level. Disability before death was significantly more severe in patients who died as a result of euthanasia than among those who died in other ways. Physician-assisted suicide appeared to occur somewhat earlier in the course of the disease than did euthanasia. An additional 48 patients (24 percent) received palliative treatment, which probably shortened their lives. In the Netherlands, we found that one in five patients with ALS died as a result of euthanasia or physician-assisted suicide.

  16. Electrodermal responses to implied versus actual violence on television.

    Science.gov (United States)

    Kalamas, A D; Gruber, M L

    1998-01-01

    The electrodermal response (EDR) of children watching a violent show was measured. Particular attention was paid to the type of violence (actual or implied) that prompted an EDR. In addition, the impact of the auditory component (sounds associated with violence) of the show was evaluated. Implied violent stimuli, such as the villain's face, elicited the strongest EDR. The elements that elicited the weakest responses were the actual violent stimuli, such as stabbing. The background noise and voices of the sound track enhanced the total number of EDRs. The results suggest that implied violence may elicit more fear (as measured by EDRs) than actual violence does and that sounds alone contribute significantly to the emotional response to television violence. One should not, therefore, categorically assume that a show with mostly actual violence evokes less fear than one with mostly implied violence.

    Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with limited therapeutic options beyond surgical resection. The characteristics of actual long-term survivors following surgical resection for ACC have not been previously reported. Patients who underwent resection for ACC at one of 13 academic institutions participating in the US Adrenocortical Carcinoma Group from 1993 to 2014 were analyzed. Patients were stratified into four groups: early mortality (died within 2 years), late mortality (died within 2-5 years), actual 5-year survivor (survived at least 5 years), and actual 10-year survivor (survived at least 10 years). Patients with less than 5 years of follow-up were excluded. Among the 180 patients available for analysis, there were 49 actual 5-year survivors (27%) and 12 actual 10-year survivors (7%). Patients who experienced early mortality had higher rates of cortisol-secreting tumors, nodal metastasis, synchronous distant metastasis, and R1 or R2 resections (all P year survivors. Ten of twelve actual 10-year survivors were women, and of the seven 10-year survivors who experienced disease recurrence, five had undergone repeat surgery to resect the recurrence. Surgery for ACC can offer a 1 in 4 chance of actual 5-year survival and a 1 in 15 chance of actual 10-year survival. Long-term survival was often achieved with repeat resection for local or distant recurrence, further underscoring the important role of surgery in managing patients with ACC. J. Surg.

  3. HIGH-EFFICIENCY INFRARED RECEIVER

    Directory of Open Access Journals (Sweden)

    A. K. Esman

    2016-01-01

    Full Text Available Recent research and development show promising use of high-performance solid-state receivers of the electromagnetic radiation. These receivers are based on the low-barrier Schottky diodes. The approach to the design of the receivers on the basis of delta-doped low-barrier Schottky diodes with beam leads without bias is especially actively developing because for uncooled receivers of the microwave radiation these diodes have virtually no competition. The purpose of this work is to improve the main parameters and characteristics that determine the practical relevance of the receivers of mid-infrared electromagnetic radiation at the operating room temperature by modifying the electrodes configuration of the diode and optimizing the distance between them. Proposed original design solution of the integrated receiver of mid-infrared radiation on the basis of the low-barrier Schottky diodes with beam leads allows to effectively adjust its main parameters and characteristics. Simulation of the electromagnetic characteristics of the proposed receiver by using the software package HFSS with the basic algorithm of a finite element method which implemented to calculate the behavior of electromagnetic fields on an arbitrary geometry with a predetermined material properties have shown that when the inner parts of the electrodes of the low-barrier Schottky diode is performed in the concentric elliptical convex-concave shape, it can be reduce the reflection losses to -57.75 dB and the standing wave ratio to 1.003 while increasing the directivity up to 23 at a wavelength of 6.09 μm. At this time, the rounded radii of the inner parts of the anode and cathode electrodes are equal 212 nm and 318 nm respectively and the gap setting between them is 106 nm. These parameters will improve the efficiency of the developed infrared optical-promising and electronic equipment for various purposes intended for work in the mid-infrared wavelength range.

    A novel technique and structure that maximizes the extraction of information from reference pulses for UWB-TR receivers is introduced. The scheme efficiently processes an incoming signal to suppress different types of UWB as well as non-UWB interference prior to signal detection. Such a method and system adds a feedback loop mechanism to enhance the signal-to-noise ratio of reference pulses in a conventional TR receiver. Moreover, sampling the second order statistical function such as, for example, the autocorrelation function (ACF) of the received signal and matching it to the ACF samples of the original pulses for each transmitted bit provides a more robust UWB communications method and system in the presence of channel distortions.

    A description of the general design of both the block 3 and block 4 receiver-exciter controllers for the Deep Space Network (DSN) Mark IV-A System is presented along with the design approach. The controllers are designed to enable the receiver-exciter subsystem (RCV) to be configured, calibrated, initialized and operated from a central location via high level instructions. The RECs are designed to be operated under the control of the DMC subsystem. The instructions are in the form of standard subsystem blocks (SSBs) received via the local area network (LAN). The centralized control provided by RECs and other DSCC controllers in Mark IV-A is intended to reduce DSN operations costs from the Mark III era.

  7. Three-dimensional comparison of alternative screw positions versus actual fixation of scaphoid fractures.

    The recommended technique for the fixation of a scaphoid waist fracture involves a headless compression screw placed in the proximal fragment center. This is usually accomplished by placing a longitudinal axis screw as visualized by fluoroscopy. The screw length has been shown to have a biomechanical advantage. An alternative to these options, which has been debated in the literature, is a screw placed perpendicular to the fracture plane and in its center. The perpendicular screw may have a biomechanical advantage despite the fact that it may be shorter. This study examined the differences in location and length in actual patients between a screw in the center of the proximal fragment with a longitudinal axis screw, and the actual fixating screw. These were then compared to a perpendicular axis screw. Pre- and post-operative CT scans of 10 patients with scaphoid waist fractures were evaluated using a 3D computer model. Comparisons were made between the length, location and angle of actual and virtual screw alternatives; namely, a screw along the central third of the proximal fragment (central screw axis) where the scaphoid longitudinal axis was calculated mathematically (longitudinal screw axis) and a screw placed at 90° to the fracture plane and in its center (perpendicular screw axis). The longitudinal axis screw was found to be significantly longer than the other axes (28.3mm). There was a significant difference between the perpendicular axis screw and the location and angle of the other screw axis, but it was only shorter than the longitudinal screw (23.6mm versus 25.5mm for the actual screw; ns.). A computed longitudinal axis screw is longer than a central or actual screw placed longitudinally by visual inspection by the surgeon. Although it needs to be placed using computer assisted (CAS) techniques, it may have the biomechanical advantages of a longer screw in a similar trajectory. The perpendicular screw was found to be significantly different in position

    2015-01-01

    Full Text Available Objective: Cancer patients have reported that information plays a significant role in their capacity to cope with cancer and manage the consequences of treatment. This study was undertaken to identify the importance older adults receiving cancer treatment assign to selected types of cancer-related information, their satisfaction with the cancer-related information they received, and the barriers to effective information provision for this age group. Methods: This study was conducted in two phases with separate samples. Six hundred and eighty-four older cancer patients receiving treatment completed a standardized survey and 39 completed a semi-structured interview to gather perspectives about cancer-related information. Data were analyzed for 65-79 years and 80+ year groups. Results: Information topics about their medical condition, treatment options, and side effects of treatment were rated as most important by the older cancer patients. Women assigned a higher importance ratings than men to information overall (t = 4.8, P < 0.01. Although participants were generally satisfied with the information, they received many described challenges they experienced in communicating with health care professionals because of the medical language and fast pace of speaking used by the professionals. Conclusions: The older cancer patients in this study endorsed the same topics of cancer-related information as most important as has been reported in studies for other age groups. However, this older group recommended that, during their interactions with older individuals, health care professionals use fewer medical words, speak at a slower pace, and provide written information in addition to the actual conversation.

  13. Social Interactions Receive Priority to Conscious Perception.

    2016-01-01

    Humans are social animals, constantly engaged with other people. The importance of social thought and action is hard to overstate. However, is social information so important that it actually determines which stimuli are promoted to conscious experience and which stimuli are suppressed as invisible? To address this question, we used a binocular rivalry paradigm, in which the two eyes receive different action stimuli. In two experiments we measured the conscious percept of rival actions and found that actions engaged in social interactions are granted preferential access to visual awareness over non-interactive actions. Lastly, an attentional task that presumably engaged the mentalizing system enhanced the priority assigned to social interactions in reaching conscious perception. We also found a positive correlation between human identification of interactive activity and the promotion of socially-relevant information to visual awareness. The present findings suggest that the visual system amplifies socially-relevant sensory information and actively promotes it to consciousness, thereby facilitating inferences about social interactions.

    Stephens, Donald R.

    2015-01-01

    CommLargo, Inc., has developed a scintillation-hardened Global Positioning System (GPS) receiver that improves reliability for low-orbit missions and complies with NASA's Space Telecommunications Radio System (STRS) architecture standards. A software-defined radio (SDR) implementation allows a single hardware element to function as either a conventional radio or as a GPS receiver, providing backup and redundancy for platforms such as the International Space Station (ISS) and high-value remote sensing platforms. The innovation's flexible SDR implementation reduces cost, weight, and power requirements. Scintillation hardening improves mission reliability and variability. In Phase I, CommLargo refactored an open-source GPS software package with Kalman filter-based tracking loops to improve performance during scintillation and also demonstrated improved navigation during a geomagnetic storm. In Phase II, the company generated a new field-programmable gate array (FPGA)-based GPS waveform to demonstrate on NASA's Space Communication and Navigation (SCaN) test bed.

  19. Diversity of MMSE MIMO Receivers

    CERN Document Server

    Mehana, Ahmed Hesham

    2011-01-01

    In most MIMO systems, the family of waterfall error curves, calculated at different spectral efficiencies, are asymptotically parallel at high SNR. In other words, most MIMO systems exhibit a single diversity value for all {\\em fixed} rates. The MIMO MMSE receiver does not follow this pattern and exhibits a varying diversity in its family of error curves. This effect cannot be captured by DMT analysis, due to the fact that all fixed rates correspond to the same multiplexing gain, thus they cannot be differentiated within DMT analysis. This work analyzes this interesting behavior of the MMSE MIMO receiver and produces the MMSE MIMO diversity at each rate. The diversity of the quasi-static flat-fading MIMO channel consisting of any arbitrary number of transmit and receive antennas is fully characterized, showing that full spatial diversity is possible for all antenna configurations if and only if the rate is within a certain bound which is a function of the number of antennas. For other rate brackets, the avail...

    A preceding randomized controlled trial demonstrated that chest compression-only cardiopulmonary resuscitation (CPR) instruction by dispatcher was more effective to increase bystander CPR than conventional CPR instruction. However, the actual condition of implementation of each type of dispatcher instruction (chest compression-only CPR [CCCPR] or conventional CPR with rescue breathing) and provision of bystander CPR in real prehospital settings has not been sufficiently investigated. This registry prospectively enrolled patients aged =>18 years suffering an out-of-hospital cardiac arrest (OHCA) of non-traumatic causes before emergency-medical-service (EMS) arrival, who were considered as target subjects of dispatcher instruction, resuscitated by EMS personnel, and transported to medical institutions in Osaka, Japan from January 2005 through December 2012. The primary outcome measure was provision of CPR by a bystander. Multiple logistic regression analysis was used to assess factors that were potentially associated with provision of bystander CPR. Among 37,283 target subjects of dispatcher instruction, 5743 received CCCPR instruction and 13,926 received conventional CPR instruction. The proportion of CCCPR instruction increased from 5.7% in 2005 to 25.6% in 2012 (p for trend bystander CPR more frequently than conventional CPR instruction group (70.0% versus 62.1%, pbystander CPR compared with conventional CPR instruction (adjusted odds ratio 1.44, 95% CI 1.34-1.55).

    Full Text Available The Five-Factor Model of personality, which includes dimensions energy, agreeableness, conscientiousness, emotional stability, and openness, gained a growing acceptance by personality researchers. In the present study the actual personality characteristics of physical educators and the personality profile of an ideal (according to subjective evaluations of experts physical educator were investigated. The aim of the study was to examine differences between profiles of actual and preferred personality characteristics and to present differences in personality characteristics between male and female physical educators of different ages. The study included 76 (40 male, 36 female 24 to 58 year-old physical educators (mean age 39.7 years. 34 experts from the field of sport, physical education, and kinesiology evaluated the preferred personality structure of an ideal physical educator. The Big Five Observer (BFO was used to assess actual and preferred personality structures. These results show that the actual personality profile of physical educators is described with all five moderately high dimensions, which is relatively congruent with the social type from Holland's typology, characteristic of educators. In comparison with participants, an ideal physical educator should have equally expressed agreeableness, while other four dimensions should be highly expressed. Gender differences in energy and agreeableness (women have higher results in both dimensions were found significant. No significant age differences in the personality structure were obtained by a cross-sectional comparison.

    Full Text Available The research objective is to manage actual problems of peatsoils associated with soil acidity. The research has been conducted on peatsoils in river backswamps located in Subdistricts of East Pedamaran and Pedamaran, District of OKI South Sumatra. Soil sampling was taken in cultivated and uncultivated types of landuse; cultivated peatsoils consist of Site A (intercropping between oil palm and pineapple and Site B (oil palm, uncultivated peatsoils are divided into Site C (peat forest, Site D (swamp bush and Site E (swamp grass. The research resulted that actual problems of soil acidity is associated with base saturation, cations exchange capacity, soil organic matters and C/N ratio, balances of soil nutrients, and toxicity potency. The climatic condition and drought can accelerate the occurrence of actual problems of peatsoils associated with acidity peatsoils. Some ameliorant have been applied in order of importance in the fields, namely lime/dolomite, mineral soils, organic fertilizers, combustion ash, and volcanic ash. Application of ameliorant materials is capable to minimize the actual problems of peatsoils associated with soil acidity.

    Instrument errors made negligible. For each integration interval, both delay and rate of change of delay initialized to small fraction of chip - for example, to order of 10 to the negative 7th power - thereby making feedback control and extraction of delay highly accurate and flexible. With appropriate selection of sampling rate relative to chip rate, commensurability errors reduced to extremely small levels. In Global Positioning System (GPS) receiver, pseudorandom code sequence generated by simple digital logic incorporating effects of time, delay, and rate of change of delay. Flexibility in starting time and sum interval very useful in aligning correlation interval with beginnings and endings of data bits.

    1995-01-01

    An experiment has been devised which will validate, in space, a miniature, high-performance receiver. The receiver blends three complementary technologies; high temperature superconductivity (HTS), pseudomorphic high electron mobility transistor (PHEMT) monolithic microwave integrated circuits (MMIC), and a miniature pulse tube cryogenic cooler. Specifically, an HTS band pass filter, InP MMIC low noise amplifier, HTS-sapphire resonator stabilized local oscillator (LO), and a miniature pulse tube cooler will be integrated into a complete 20 GHz receiver downconverter. This cooled downconverter will be interfaced with customized signal processing electronics and integrated onto the space shuttle's 'HitchHiker' carrier. A pseudorandom data sequence will be transmitted to the receiver, which is in low Earth orbit (LEO), via the Advanced Communication Technology Satellite (ACTS) on a 20 GHz carrier. The modulation format is QPSK and the data rate is 2.048 Mbps. The bit error rate (BER) will be measured in situ. The receiver is also equipped with a radiometer mode so that experiment success is not totally contingent upon the BER measurement. In this mode, the receiver uses the Earth and deep space as a hot and cold calibration source, respectively. The experiment closely simulates an actual cross-link scenario. Since the receiver performance depends on channel conditions, its true characteristics would be masked in a terrestrial measurement by atmospheric absorption and background radiation. Furthermore, the receiver's performance depends on its physical temperature, which is a sensitive function of platform environment, thermal design, and cryocooler performance. This empirical data is important for building confidence in the technology.

    Jamin, Olivier

    2014-01-01

    This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains.  A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis.  Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm...

    The Actual Curriculum Development Practices Instrument (ACDP-I) was developed and the factorial validity of the ACDP-I was tested (n = 107) using exploratory factor analysis procedures in the earlier work of [1]. Despite the ACDP-I appears to be content and construct valid instrument with very high internal reliability qualities for using in Malaysia, the accumulated evidences are still needed to provide a sound scientific basis for the proposed score interpretations. Therefore, the present study addresses this concern by utilising the confirmatory factor analysis to further confirm the theoretical structure of the variable Actual Curriculum Development Practices (ACDP) and enrich the psychometrical properties of ACDP-I. Results of this study have practical implication to both researchers and educators whose concerns focus on teachers' classroom practices and the instrument development and validation process.

    Full Text Available This study reviews the potential of tablet technology for teaching and learning. In autumn 2012, we conducted a focused survey comprising quantitative and qualitative questions with Finnish teachers (N = 171, from 54 schools. We focused on perceived pedagogical opportunities and the actualized pedagogical potential of tablets at schools. The survey results indicate that the actual usefulness of tablets in schools was significantly less than what teachers perceived as the pedagogical potential. However, the results demonstrate the positive impact these devices are having on teaching and learning, as well as prompting changes in pedagogical perspectives. Teachers stated that tablets can diversify and enhance teaching and learning in many ways, particularly in supporting learners’ motivation and independent learning, and promoting engaging teaching methods. Nevertheless, teachers voiced concern that the student-to-device ratio at the moment is too low, thus serving as a barrier to widespread use of tablets.

This paper proposes a model of an intelligent generator for semi-actual test data with the aim of increasing users confidence in software testing. The model uses samples of real data as a resource data and a set of efficient generation techniques based on statistical methods such as permutations, combination, sampling, and statistical distributions. The selection of the suitable structure and generation technique is based on one of the intelligent soft computing techniques such as fuzzy logic, neural network, heuristic, or genetic algorithm. The generated test data is validated according to the data specifications then tested by one of the normality testing techniques to be close to the real world or environment of the testing processes. This model offers the ability of simulating real environments.Key Words: Software Testing, Test Data Generation, Semi-Actual Data, Intelligent Generator, Simulation.

  17. Perceived and Actual Weight Stigma Among Romantic Couples

    Full Text Available According to research on weight bias, relationship stigma may be greater among romantic couples comprised of at least one overweight partner, as compared to two healthy-weight partners. However, comparison theories predict that the stigma of being overweight may be greater among mixed-weight couples (i.e., romantic partners with dissimilar body mass indexes; BMI than matched-weight couples (e.g., similarly overweight partners. To test these rival hypotheses, we assessed perceived and actual stigma experienced by mixed-weight and matched-weight couples. In two studies, people inferred (Study 1 or reported the actual amount (Study 2 of relational stigma and weight-related discomfort experienced by a healthy-weight/overweight person in a mixed/matched-weight relationship. Supporting the weight bias hypothesis, people inferred overweight people and their partners experience greater stigma and weight-related discomfort (Study 1. However, only overweight people in a matched-weight, as compared to mixed-weight, relationships actually reported greater relational stigma and weight-related discomfort (Study 2.

    Cryogenic probes have significantly increased the sensitivity of NMR. Here, we present a compact EPR receiver design capable of cryogenic operation. Compared to room temperature operation, it reduces the noise by a factor of ≈2.5. We discuss in detail the design and analyze the resulting noise performance. At low microwave power, the input noise density closely follows the emission of a cooled 50Ω resistor over the whole measurement range from 20K up to room temperature. To minimize the influence of the microwave source noise, we use high microwave efficiency (≈1.1-1.7mTW(-1/2)) planar microresonators. Their efficient conversion of microwave power to magnetic field permits EPR measurements with very low power levels, typically ranging from a few μW down to fractions of nW.

  2. International population assistance: a spur to national effort.

    Salas, R M

    1974-01-01

    A continuing role for multilateral assitance in population will exist. Only international organizations can adequately transmit information, provide multinational experts and transmit certain technical advances in the population field. Aid-receiving countries must show both the realistic and necessary objectives and the will to execute their plans. A serious concern of aid administrators today is the probability that the volume of development assistance which showed an accelerated rate of increase in its early years is indefinitely at a plateau. Many varied reasons for this exist including the sharp, troublesome changes in world trade patterns, a crescendo of accusations of ineffective aid and a very slow rise, if any, in net per capita production. Aid-receiving countries have been discontent because of tied loans and allegations that aid has had inflationary results. Unlike other development projects, population programs often take a generation or more to take full effect. It is sometimes claimed that rapid population growth is the single most important obstacle to improved living standards. This opinion is not universally agreed on, however. Other possible obstacles are neglect of agriculture, lack of adequate infrastructure to develop markets and rigid social structures. A reduction in the population growth rate may actually be a serious hindrance to the attainment of economic and social goals. International assistance has only been a marginal addition to the total development resources of aid-receiving countries, although it has made a major contribution to the initial implementation of population programs, especially in India and China. Aid should be given in those basic areas which will yield better returns in the long run. It should be a 'spur' rather than a catalyst, which is only effective in a short-term crisis. The main aim is the creation of clear national population goals toward which the nation's human resources should be mobilized according to its

    2009-12-20

    By input of the actual dose of a drug given into a radiology information system, the system converting with an accounting system into a cost of the drug from the actual dose in the electronic medical record was built. In the drug master, the first unit was set as the cost of the drug, and we set the second unit as the actual dose. The second unit in the radiology information system was received by the accounting system through electronic medical record. In the accounting system, the actual dose was changed into the cost of the drug using the dose of conversion to the first unit. The actual dose was recorded on a radiology information system and electronic medical record. The actual dose was indicated on the accounting system, and the cost for the drug was calculated. About the actual dose of drug, cooperation of the information in a radiology information system and electronic medical record were completed. It was possible to decide the volume of drug from the correct dose of drug at the previous inspection. If it is necessary for the patient to have another treatment of medicine, it is important to know the actual dose of drug given. Moreover, authenticity of electronic medical record based on a statute has also improved.

  6. Vertebrate pressure-gradient receivers.

    Science.gov (United States)

    Christensen-Dalsgaard, Jakob

    2011-03-01

    The eardrums of all terrestrial vertebrates (tetrapods) are connected through Eustachian tubes or interaural canals. In some of the animals, these connections create pressure-gradient directionality, an enhanced directionality by interaction of sound arriving at both sides of the eardrum and strongly dependent on interaural transmission attenuation. Even though the tympanic middle ear has originated independently in the major tetrapod groups, in each group the ancestral condition probably was that the two middle ears were exposed in the mouth cavity with relatively high interaural transmission. Recent vertebrates form a continuum from perfect interaural transmission (0 dB in a certain frequency band) and pronounced eardrum directionality (30-40 dB) in the lizards, over somewhat attenuated transmission and limited directionality in birds and frogs, to the strongly attenuated interaural transmission and functionally isolated pressure receiver ears in the mammals. Since some of the binaural interaction already takes place at the eardrum in animals with strongly coupled ears, producing enhanced interaural time and level differences, the subsequent neural processing may be simpler. In robotic simulations of lizards, simple binaural subtraction (EI cells, found in brainstem nuclei of both frogs and lizards) produces strongly lateralized responses that are sufficient for steering the animal robustly to sound sources.

    A description is given of recent work at Berkeley on superconducting mixers and detectors for infrared and millimeter wavelengths. The first report is a review article which summarizes the status of development of superconducting components for infrared and millimeter wave receivers. The next report describes accurate measurements and also theoretical modeling of an SIS quasiparticle waveguide mixer for W-band which uses very high quality Ta junctions. The best mixer noise is only 1.3 times the quantum limit. Both the mixer gain and the noise are in quantitative agreement with the quantum theory. Next, a report is given on measurements and theoretical modeling of the absorptivity (surface resistance) of high quality epitaxial films of the high Tc superconductor YBCO from 750 GHz to 21 THz. Finally, there are reports on the design and experimental performance of two different types of high Tc bolometric detectors. One is a conventional bolometer with a gold-black absorber. The other is an antenna coupled microbolometer.

    The advent of robot-assisted laparoscopy (RAL) represents an important innovation and has opened new perspectives for treatment of endometriosis, in particular in deep infiltrating endometriosis (DIE). RAL could offer several technical advantages in treating this complex disease, such as 3D vision, tremor filtration and better surgical ergonomy, would be able to improve surgical performances without increasing in surgical time, blood loss, intra- and postoperative complications and it reduces the rates of conversion to laparotomy. Additionally thanks to its reduced learning curve compared to conventional laparoscopy, facilitates the training of less experienced surgeons. For these reason DIE might be one of the best indications for robot assisted laparoscopy in gynecologic surgery. However, very few retrospective studies, small cases series and only a randomized clinical trial were reported. Further randomized control trial comparing CL to RAL for different stage of endometriosis and the different type of procedure performed would be mandatory in order to define potential benefits of RAL for endometriosis surgery.

  12. Actual Versus Predicted Cardiovascular Demands in Submaximal Cycle Ergometer Testing.

    Science.gov (United States)

    Hoehn, Amanda M; Mullenbach, Megan J; Fountaine, Charles J

    The Astrand-Rhyming cycle ergometer test (ARCET) is a commonly administered submaximal test for estimating aerobic capacity. Whereas typically utilized in clinical populations, the validity of the ARCET to predict VO2max in a non-clinical population, especially female, is less clear. Therefore, the purpose of this study was to determine the accuracy of the ARCET in a sample of healthy and physically active college students. Subjects (13 females, 10 males) performed a maximal cycle ergometer test to volitional exhaustion to determine VO2max. At least 48 hours later, subjects performed the ARCET protocol. Predicted VO2max was calculated following the ARCET format using the age corrected factor. There was no significant difference (p=.045) between actual (41.0±7.97 ml/kg/min) and predicted VO2max (40.3±7.58 ml/kg/min). When split for gender there was a significant difference between actual and predicted VO2 for males, (45.1±7.74 vs. 42.7±8.26 ml/kg/min, p=0.029) but no significant difference observed for females, (37.9±6.9 vs. 38.5±6.77 ml/kg/min, p=0.675). The correlation between actual and predicted VO2 was r=0.84, pVO2max in a healthy college population of both male and female subjects. Implications of this study suggest the ARCET can be used to assess aerobic capacity in both fitness and clinical settings where measurement via open-circuit spirometry is either unavailable or impractical.

    2016-01-01

    Wound healing is an intricate process that involves many types of cells, reaction pathways as well as chemical, physical and electrical cues. Since biochemical reactions and physiological events are pH-dependent we study here pH as an important major characteristic of the wound healing process in the presence of endogenous and exogenous electric fields. Our model gives the spatial pH distribution in a wound. In particular we isolate a number of dimensionless quantities which sets the length, energy and time scales governing the wound healing process and which can be experimentally tested. Most interesting finding is that wound pH depends on actual wound size.

  3. Judgments of learning are significantly higher following feedback on relatively good versus relatively poor trials despite no actual learning differences.

    Science.gov (United States)

    Carter, Michael J; Smith, Victoria; Ste-Marie, Diane M

    2016-02-01

    Studies have consistently shown that prospective metacognitive judgments of learning are often inaccurate because humans mistakenly interpret current performance levels as valid indices of learning. These metacognitive discrepancies are strongly related to conditions of practice. Here, we examined how the type of feedback (after good versus poor trials) received during practice and awareness (aware versus unaware) of this manipulation affected judgments of learning and actual learning. After each six-trial block, participants received feedback on their three best trials or three worst trials and half of the participants were made explicitly aware of the type of feedback they received while the other half were unaware. Judgments of learning were made at the end of each six-trial block and before the 24-h retention test. Results indicated no motor performance differences between groups in practice or retention; however, receiving feedback on relatively good compared to relatively poor trials resulted in significantly higher judgments of learning in practice and retention, irrespective of awareness. These results suggest that KR on relatively good versus relatively poor trials can have dissociable effects on judgments of learning in the absence of actual learning differences, even when participants are made aware of their feedback manipulation.

    Full Text Available Ray Kurzweil and others have posited that the confluence of nanotechnology, artificial intelligence, robotics, and genetic engineering will soon produce posthuman beings that will far surpass us in power and intelligence. Just as black holes constitute a ldquo;singularityrdquo; from which no information can escape, posthumans will constitute a ldquo;singularity:rdquo; whose aims and capacities lie beyond our ken. I argue that technological posthumanists, whether wittingly or unwittingly, draw upon the long-standing Christian discourse of ldquo;theosis,rdquo; according to which humans are capable of being God or god-like. From St. Paul and Luther to Hegel and Kurzweil, the idea of human self-deification plays a prominent role. Hegel in particular emphasizes that God becomes wholly actualized only in the process by which humanity achieves absolute consciousness. Kurzweil agrees that God becomes fully actual only through historical processes that illuminate and thus transform the entire universe. The difference is that for Kurzweil and many other posthumanists, our offspringmdash;the posthumansmdash;will carry out this extraordinary process. What will happen to Home sapiens in the meantime is a daunting question.br /br /

    2013-09-01

    Full Text Available Within the hydrological cycle, actual evaporation represents the second most important process in terms of volumes of water transported, second only to the precipitation phenomena. Several methods for the estimation of the Ea were proposed by researchers in scientific literature, but the estimation of the Ea from potential evapotranspiration often requires the knowledge of hard-to-find parameters (e.g.: vegetation morphology, vegetation cover, interception of rainfall by the canopy, evaporation from the canopy surface and uptake of water by plant roots and many existing database are characterized by missing or incomplete information that leads to a rough estimation of the actual evaporation amount. Starting from the above considerations, the aim of this study is to develop and validate a method for the estimation of the Ea based on two steps: i the potential evaporation estimation by using the meteorological data (i.e. Penman-Monteith; ii application of a correction factor based on the infrared soil surface temperature measurements. The dataset used in this study were collected during two measurement campaigns conducted both in a plain testing site (Grugliasco, Italy, and in a mountain South-East facing slope (Cogne, Italy. During those periods, hourly measurement of air temperature, wind speed, infrared surface temperature, soil heat flux, and soil water content were collected. Results from the dataset collected in the two testing sites show a good agreement between the proposed method and reference methods used for the Ea estimation.

We understand education as an important form of social consciousness in the sense of bipolarity, namely as the premise and the effect at a dynamic microeconomic and macroeconomic level. In this dynamic movement, economic education appears more and more visibly as a new factor of production or as a new dimension of human capital. In our approach we consider several theoretical and methodological axes that allow us to reveal the interdependence of education to the economic and social development, from an emulative or frantic perspective. In this way we treat the evolution of complex phenomena of economic education in terms of public policy, highlighting the need to intensify the decision-making efforts of management and execution, consistent pursuing to link the causes with the effects of economic education in the Romanian actuality.

  11. What do tests of formal reasoning actually measure?

    Science.gov (United States)

    Lawson, Anton E.

    Tests of formal operational reasoning derived from Piagetian theory have been found to be effective predictors of academic achievement. Yet Piaget's theory regarding the underlying nature of formal operations and their employment in specific contexts has run into considerable empirical difficulty. The primary purpose of this study was to present the core of an alternative theory of the nature of advanced scientific reasoning. That theory, referred to as the multiple-hypothesis theory, argues that tests of formal operational reasoning actually measure the extent to which persons have acquired the ability to initiate reasoning with more than one specific antecedent condition, or if they are unable to imagine more than one antecedent condition, they are aware that more than one is possible; therefore conclusions that are drawn are tempered by this possibility. As a test of this multiple-hypothesis theory of advanced reasoning and the contrasting Piagetian theory of formal operations, a sample of 922 college students were first classified as concrete operational, transitional, or formal operational, based upon responses to standard Piagetian measures of formal operational reasoning. They were then administered seven logic tasks. Actual response patterns to the tasks were analyzed and found to be similar to predicted response patterns derived from the multiple-hypothesis theory and were different from those predicted by Piagetian theory. Therefore, support was obtained for the multiple-hypothesis theory. The terms intuitive and reflective were suggested to replace the terms concrete operational and formal operational to refer to persons at varying levels of intellectual development.

    Full Text Available La angina de pecho crónica estable es un síndrome clínico caracterizado por dolor o malestar precordial secundario a isquemia miocárdica y sin características clínicas de inestabilidad. El debate actual sobre esta entidad clínica incluye tres aspectos fundamentales: diagnóstico, prevalencia e impacto socioeconómico, y tratamiento médico frente a revascularización miocárdica. En los últimos cuatro años se han dado a conocer los resultados de varios estudios multicéntricos de gran importancia que compararon tratamiento médico con revascularización miocárdica y cirugía de revascularización frente a intervención coronaria percutánea; además, han mejorado las técnicas de revascularización y existe abundante información sobre la eficacia de nuevos fármacos antiisquémicos. El presente trabajo tiene como objetivo hacer una revisión de los aspectos actuales más importantes relacionados con la angina de pecho estable y su tratamiento, publicados en la literatura especializada.

    Full Text Available Disabled people face barriers in performing their various activities, including teaching. By using assistive technologies for different activities, people with disabilities may be able to perform a wider range of tasks independently. Fortunately, it helps to reduce many of these barriers, but, unfortunately, disabled people (learning, autism or ADHD face a variety of barriers when they want to use software tools or hardware devices. In this regard, assistive technologies are available to help persons with different types of disabilities, from cognitive problems to physical impairment. Hardware devices and software tools (known as adaptive or assistive technologies have been developed to provide functional alternatives for all individuals with disabilities, depending on the type of disability. In addition, the use of assistive technologies to support them is an effective approach for many persons with disabilities, regardless of the type of disability. Additionally, individuals with disabilities often experience greater success when they are allowed to use their abilities to work around their disabilities (the challenges they imply. Moreover, mobile devices are useful for their ability to weave Internet access and social networking into the daily life. To the people with disabilities, these devices have the potential to unlock unprecedented new possibilities for communication or navigation. In this context, some actual assistive technology and approaches to use them are described in this paper.

  14. [Physician-assisted suicide in dementia?].

    Science.gov (United States)

    Lauter, H

    2011-01-01

    Physician-assisted suicide in Germany is limited by criminal law and disapproved by professional authorities. A physician who is willing to help a demented patient in terminating his life has to be definitely sure that the disease does not interfere with the patient's capacity for decision-making. In cases of early dementia the reason why assisted suicide will usually be requested is not the actual suffering of the patient but his negative expectations for the future. As long as there are sufficient opportunities for palliative care, the progressive course of the dementia process does not imply a state of unbearable suffering which could justify an assisted suicide. Nevertheless there may be certain circumstances--as for instance the value that an individual attributes to his integrity or to the narrative unity of his life--which might possibly provide an ethical justification for the assistance in life termination. A physician who helps a demented person in performing a suicidal act does not necessarily oppose essential principles of medical ethics. Yet, especially with regard to possible societal consequences of physician-assisted suicide in dementia, the rejecting attitude of medical authorities against that activity must be considered as well founded and legitimate. Deviations from these general guidelines ought to be respected as long as they are limited to exceptional situations and correspond to a thorough consideration of a physician's professional duties. They should remain open to public control, but not be ultimately specified by unequivocal normative regulations.

  16. Thermal resistance model for CSP central receivers

    2016-05-01

    The receiver design and heliostat field aiming strategy play a vital role in the heat transfer efficiency of the receiver. In molten salt external receivers, the common operating temperature of the heat transfer fluid or molten salt ranges between 285°C to 565°C. The optimum output temperature of 565°C is achieved by adjusting the mass flow rate of the molten salt through the receiver. The reflected solar radiation onto the receiver contributes to the temperature rise in the molten salt by means of heat transfer. By investigating published work on molten salt external receiver operating temperatures, corresponding receiver tube surface temperatures and heat losses, a model has been developed to obtain a detailed thermographic representation of the receiver. The steady state model uses a receiver flux map as input to determine: i) heat transfer fluid mass flow rate through the receiver to obtain the desired molten salt output temperature of 565°C, ii) receiver surface temperatures iii) receiver tube temperatures iv) receiver efficiency v) pressure drop across the receiver and vi) corresponding tube strain per panel.

  17. Laser-assisted hatching in assisted reproduction.

    Montag, M; van der Ven, H

    1999-09-01

    The use of a 1.48 um diode laser for assisted hatching was investigated in animal experimentation. Laser assisted hatching was offered to patients with advanced maternal age to evaluate a possible benefit. Using the Fertilase(r) system we investigated the impact of openings with different size in the zona of mouse embryos on the hatching process, as well as that of two openings. Laser-drilling was performed at the blastocyst stage to look for differences in timing and efficacy of hatching. The possible benefit of assisted hatching was studied in 24 couples with advanced maternal age (38.8+2.1 years) and compared to a control group (37.8+2.5 years) treated in the same time period but without assisted hatching. A certain diameter of a laser drilled opening in the zona pellucida is necessary for efficient hatching. When two openings are present in the zona, the embryo will use both openings for hatching and subsequently become trapped. Laser-drilling at th e expanded blastocyst stage causes an immediate collapse of treated blastocysts and the onset of hatching is retarded. Assisted hatching in 24 patients with advanced maternal age resulted in a significant increase (plaser to drill an opening into the zona pellucida provides a good alternate to conventionally applied techniques. The procedure is efficient and safe as long as it is applied properly. In a human in vitro fertilization program, selected patients will have a benefit form assisted hatching.

  8. Thomas-Wigner rotation and Thomas precession: actualized approach

    CERN Document Server

    Kholmetskii, Alexander

    2014-01-01

    We show that the explanation of Thomas-Wigner rotation (TWR) and Thomas precession (TP) in the framework of special theory of relativity (STR) contains a number of points of inconsistency, in particular, with respect to physical interpretation of the Einstein velocity composition law in successive space-time transformations. In addition, we show that the common interpretation of TP falls into conflict with the causality principle. In order to eliminate such a conflict, we suggest considering the velocity parameter, entering into expression for the frequency of TP, as being always related to a rotation-free Lorentz transformation. Such an assumption (which actually resolves any causal paradoxes with respect to TP), comes however to be in contradiction with the spirit of STR. The results obtained are discussed.

    2017-04-01

    It's well known that street trees cool air temperature in summer-time by transpiration and shading and also reduce runoff. However, it's difficult to analyse if trees have water shortage or not. This contribution focus on predicting water supply, actual evapotranspiration, and runoff by using easily available climate data (precipiation, potential evapotranspiration) and site characteristics (water retention, space, sealing degree, groundwater depth). These parameter were used as input data for Hydro-Pedotransfer-Functions (HPTFs) allowing the estimation of the annual water budget. Results give statements on water supply of trees, drought stress, and additional water demand by irrigation. Procedure also analyse, to which extent the surrounding partly sealed surfaces deliver water to the trees. Four representative street canyons of Berlin City were analysed and evaluated within in training program for M.A. students of „Urban Eco-system Science" at the Technische Universität Berlin.

    Science.gov (United States)

    1999-10-29

    The "actual exposure" rule can now be applied in Hawaii to cases involving the recovery of damages for HIV exposure even if the virus is not transmitted. This ruling came as a result of the case of three airport baggage handlers who were exposed to a leaking container of HIV-positive blood. The Hawaii Supreme Court ruled that a plaintiff has to prove that the exposure involves a "scientifically accepted" method of transmission and that the fluid in question contained HIV. Furthermore, the court ruled, any liability for mental distress is limited to the time between discovery of contamination and confirmation that no infection resulted. With current testing standards, the time period between discovery and a negative test result is approximately 3 to 6 months.

    Full Text Available Eco-friendly energies have recently become a popular topic. Given this trend, we predict that a large number of electric vehicles (EVs will be widely used. However, EVs need to be connected to a power system for charging, thereby causing severe risks, such as rapid increase of demand power. Therefore, in this study, we analyze the effects of EV charging on demand power, which depend on different charging schemes, namely, dumb charging, off-peak charging, time-of-use (ToU price-based charging. For practical analysis, we conduct simulations by considering the actual power system and driving patterns in South Korea. Simulation results show that the ToU price-based charging scheme exhibits better performance in terms of demand power over the other charging schemes.

  5. Non-actual motion: phenomenological analysis and linguistic evidence.

    Science.gov (United States)

    Blomberg, Johan; Zlatev, Jordan

    2015-09-01

    Sentences with motion verbs describing static situations have been seen as evidence that language and cognition are geared toward dynamism and change (Talmy in Toward a cognitive semantics, MIT Press, Cambridge, 2000; Langacker in Concept, image, and symbol: the cognitive basis of grammar, Mouton de Gruyter, Berlin and New York, 1990). Different concepts have been used in the literature, e.g., fictive motion, subjective motion and abstract motion to denote this. Based on phenomenological analysis, we reinterpret such concepts as reflecting different motivations for the use of such constructions (Blomberg and Zlatev in Phenom Cogn Sci 13(3):395-418, 2014). To highlight the multifaceted character of the phenomenon, we propose the concept non-actual motion (NAM), which we argue is more compatible with the situated cognition approach than explanations such as "mental simulation" (e.g., Matlock in Studies in linguistic motivation, Mouton de Gruyter, Berlin, 2004). We investigate the expression of NAM by means of a picture-based elicitation task with speakers of Swedish, French and Thai. Pictures represented figures that either afford human motion or not (±afford); crossed with this, the figure extended either across the picture from a third-person perspective (3 pp) or from a first-person perspective (1 pp). All picture types elicited NAM-sentences with the combination [+afford, 1 pp] producing most NAM-sentences in all three languages. NAM-descriptions also conformed to language-specific patterns for the expression of actual motion. We conclude that NAM shows interaction between pre-linguistic motivations and language-specific conventions.

  6. Thermoregulation during prolonged actual and laboratory-simulated bicycling.

    Science.gov (United States)

    Brown, S L; Banister, E W

    1985-01-01

    Thermoregulatory and cardiorespiratory responses to bicycling 55 km (mean speed 9.7 m X s-1) outdoors (15 degrees C DB) were compared to equivalent cycle ergometry (90 min at 65% VO2max) in the laboratory (20-23 degrees C DB, 50% RH) in 7 trained cyclists. Outdoor environmental conditions were simulated with fans and lamps, and were contrasted with standard no-wind, no-sun laboratory conditions. Sweating rate was similar during outdoor and laboratory simulated outdoor cycling (0.90 and 0.87 to 0.94 1 X h-1 respectively). During outdoor bicycling, mean heart rate (161 bt X min-1) was 7-13% higher (p less than .05) than under laboratory conditions, suggesting a greater strain for a similar external work rate. The increase in rectal temperature (0.8 degrees C) was 33-50% less (p less than 0.05) at the cooler outdoor ambient temperature than in the laboratory. Thermoregulatory stress was greater under the no-fan, no-lamp laboratory condition than during simulated outdoor conditions (36-38% greater (p less than 0.05) sweating rate, 15-18% greater (p less than 0.01) mean skin temperature, 6.4 to 7.8 fold greater (p less than 0.01) amount of clothing-retrained sweat). The cooling wind encountered in actual road bicycling apparently reduces thermoregulatory and circulatory demands compared with stationary cycle ergometry indoors. Failure to account for this enhanced cooling may result in overestimation of the physiological stress of actual road cycling.(ABSTRACT TRUNCATED AT 250 WORDS)

  7. Drone based estimation of actual evapotranspiration over different forest types

    Marzahn, Philip; Gampe, David; Castro, Saulo; Vega-Araya, Mauricio; Sanchez-Azofeifa, Arturo; Ludwig, Ralf

    2017-04-01

    Actual evapotranspiration (Eta) plays an important role in surface-atmosphere interactions. Traditionally, Eta is measured by means of lysimeters, eddy-covariance systems or fiber optics, providing estimates which are spatially restricted to a footprint from a few square meters up to several hectares . In the past, several methods have been developed to derive Eta by means of multi-spectral remote sensing data using thermal and VIS/NIR satellite imagery of the land surface. As such approaches do have their justification on coarser scales, they do not provide Eta information on the fine resolution plant level over large areas which is mandatory for the detection of water stress or tree mortality. In this study, we present a comparison of a drone based assessment of Eta with eddy-covariance measurements over two different forest types - a deciduous forest in Alberta, Canada and a tropical dry forest in Costa Rica. Drone based estimates of Eta were calculated applying the Triangle-Method proposed by Jiang and Islam (1999). The Triangle-Method estimates actual evapotranspiration (Eta) by means of the Normalized Difference Vegetation Index (NDVI) and land surface temperature (LST) provided by two camera systems (MicaSense RedEdge, FLIR TAU2 640) flown simultaneously on an octocopter. . Results indicate a high transferability of the original approach from Jiang and Islam (1999) developed for coarse to medium resolution satellite imagery tothe high resolution drone data, leading to a deviation in Eta estimates of 10% compared to the eddy-covariance measurements. In addition, the spatial footprint of the eddy-covariance measurement can be detected with this approach, by showing the spatial heterogeneities of Eta due to the spatial distribution of different trees and understory vegetation.

    In the context of assisted ventilation in ICU, it is of vital importance to keep a high synchronization between the patient's attempt to breath and the assisted ventilation event, so that the patient receives the ventilation support requested. In this work, experimental equipment is employed, which allows for unobtrusive and continuous monitoring of a multiple relevant bioparameters. These are meant to guide the medical professionals in appropriately adapting the treatment and fine-tune the ventilation. However, synchronization phenomena of different origin (neurological, mechanical, ventilation parameters) may occur, which vary among patients, and during the course of monitoring of a single patient, the timely recognition of which is challenging even for experts. The dynamics and complex causal relations among bioparameters and the ventilation synchronization are not well studied. The purpose of this work is to elaborate on a methodology toward modeling the ventilation synchronization failures based on the evolution of monitored bioparameters. Principal component analysis is employed for the transformation into a small number of features and the investigation of repeating patterns and clusters within measurements. Using these features, nonlinear prediction models based on support vector machines regression are explored, in terms of what past knowledge is required and what is the future horizon that can be predicted. The proposed model shows good correlation (over 0.74) with the actual outputs, constituting an encouraging step toward understanding of ICU ventilation dynamic phenomena.

    The first six Atacama Large Millimeter/submillimeter Array (ALMA) Band 10 (787-950 GHz) receivers have been developed and characterized during the receiver preproduction phase. State-of-the-art measurement systems at THz frequencies have been implemented and successfully used to measure the performance of the first six receivers. Extensive tests ranging from receiver sensitivity and stability to optical aperture efficiency on the secondary antenna have been performed. Performance of all six receivers is well within the stringent ALMA requirements. Moreover, our extensive tests have shown that there are no big performance differences between receivers. These results indicate that the ALMA Band 10 receiver is ready for the production phase, during which an additional 67 receivers will be produced and characterized.

    As part of the ongoing remediation process at the Maywood Formerly Utilized Sites Remedial Action Program (FUSRAP) properties, Argonne National Laboratory (Argonne) assisted the U.S. Army Corps of Engineers (USACE) New York District by providing contaminated soil volume estimates for the main site area, much of which is fully or partially remediated. As part of the volume estimation process, an initial conceptual site model (ICSM) was prepared for the entire site that captured existing information (with the exception of soil sampling results) pertinent to the possible location of surface and subsurface contamination above cleanup requirements. This ICSM was based on historical anecdotal information, aerial photographs, and the logs from several hundred soil cores that identified the depth of fill material and the depth to bedrock under the site. Specialized geostatistical software developed by Argonne was used to update the ICSM with historical sampling results and down-hole gamma survey information for hundreds of soil core locations. The updating process yielded both a best guess estimate of contamination volumes and a conservative upper bound on the volume estimate that reflected the estimate's uncertainty. Comparison of model results to actual removed soil volumes was conducted on a parcel-by-parcel basis. Where sampling data density was adequate, the actual volume matched the model's average or best guess results. Where contamination was un-characterized and unknown to the model, the actual volume exceeded the model's conservative estimate. Factors affecting volume estimation were identified to assist in planning further excavations. (authors)

    This report describes both a general methodology and some specific examples of passive radio receivers. A passive radio receiver uses no direct electrical power but makes sole use of the power available in the radio spectrum. These radio receivers are suitable as low data-rate receivers or passive alerting devices for standard, high power radio receivers. Some zero-power radio architectures exhibit significant improvements in range with the addition of very low power amplifiers or signal processing electronics. These ultra-low power radios are also discussed and compared to the purely zero-power approaches.

  19. Tutorial on Actual Space Environmental Hazards For Space Systems (Invited)

    It has become common in the space science community to conduct research on diverse physical phenomena because they are thought to contribute to space weather. However, satellites contend with only three primary environmental hazards: single event effects, vehicle charging, and total dose, and not every physical phenomenon that occurs in space contributes in substantial ways to create these hazards. One consequence of the mismatch between actual threats and all-encompassing research is the often-described gap between research and operations; another is the creation of forecasts that provide no actionable information for design engineers or spacecraft operators. An example of the latter is the physics of magnetic field emergence on the Sun; the phenomenon is relevant to the formation and launch of coronal mass ejections and is also causally related to the solar energetic particles that may get accelerated in the interplanetary shock. Unfortunately for the research community, the engineering community mitigates the space weather threat (single-event effects from heavy ions above ~50 MeV/nucleon) with a worst-case specification of the environment and not with a prediction. Worst-case definition requires data mining of past events, while predictions involve large-scale systems science from the Sun to the Earth that is compelling for scientists and their funding agencies but not actionable for design or for most operations. Differing priorities among different space-faring organizations only compounds the confusion over what science research is relevant. Solar particle impacts to human crew arise mainly from the total ionizing dose from the solar protons, so the priority for prediction in the human spaceflight community is therefore much different than in the unmanned satellite community, while both communities refer to the fundamental phenomenon as space weather. Our goal in this paper is the presentation of a brief tutorial on the primary space environmental phenomena

    Although efforts are underway to examine marketing that targets the youth and families in the retail food store environment, few studies have specifically focused on stores that families identify as their primary sites for food shopping. Between November 2011 and April 2012, we examined the frequency and types of marketing techniques of 114 packaged and nonpackaged items in 24 food stores that mothers of young children in Champaign County, IL, said they commonly frequented. Chi-square tests were used to determine whether significant differences existed between items with regard to marketing by store type, store food-assistance-program acceptance (i.e., WIC), and claims. Overall, stores accepting WIC and convenience stores had higher frequencies of marketing compared to non-WIC and grocery stores. Fruits and vegetables had the lowest frequency of any marketing claim, while salty snacks and soda had the highest frequency of marketing claims. Nutrition claims were the most common across all items, followed by taste, suggested use, fun, and convenience. Television tie-ins and cartoons were observed more often than movie tie-ins and giveaways. Our results suggest an opportunity to promote healthful items more efficiently by focusing efforts on stores where mothers actually shop.

    Full Text Available The study aims to argue that the humanist model of medicine approaches the practice of self-care, the latter being an actualization of the former concerning all those ideas and issues in which they overlap. The humanisitic model covers pacient-centred medicine and offers a holistic approach to the patient which involves treating him/her as a patient, not as a body (as in biomedicine, emphasizes the doctor-patient partnership atmosphere, a relational, communicational and informational environment. The concept of spatialization in philosophy came out as an empirical mecanicist model in sciences and influenced the appearance of the biomedical model. In the humanistic model, the patient can be, to a certain extent, the factor making decisions with regard to the chronic disease. Self-care matches especially the human medicine with regard to the outlook on the patient as a person (holism, the long-term partnership in the communication, information and correct decision-making for the disease, the empathic environment, the responsibility shared between two people, the assistance provided when making decisions for the patient’s “friendship”with the chronic disease.

    Ceci, Stephen J; Williams-Ceci, Sterling; Williams, Wendy M

    2016-08-01

    Bioecological theory posits three interacting principles to explain developmental outcomes such as fluctuating achievement levels and changing heritability coefficients. Here, we apply the theory to the domain of talent development, by reviewing short-term and long-term cognitive interventions. We argue that macro-level analyses of cultural practices (e.g., matrilineal inheritance and property ownership) and national systems of education are consistent with the bioecological theory; when the findings from these analyses are unpacked, the engines that drive them are so-called proximal processes. This finding has implications for the design and delivery of instruction and the development of talent. We argue that talent is fostered by the same three bioecological mechanisms that explain the actualization of genetic potential. We conclude by discussing several self-descriptions and personal narratives by gifted students in which they spontaneously refer to these bioecological mechanisms in their own talent-development processes. Similar testimonials have been documented by historic talent researchers such as Benjamin Bloom, noting the importance of continual adjustments in feedback. © 2016 New York Academy of Sciences.

  6. Actual Pathogen Detection: Sensors and Algorithms - a Review

    Directory of Open Access Journals (Sweden)

    2009-03-01

    Full Text Available Pathogens feed on fruits and vegetables causing great food losses or at least reduction of their shelf life. These pathogens can cause losses of the final product or in the farms were the products are grown, attacking leaves, stems and trees. This review analyses disease detection sensors and algorithms for both the farm and postharvest management of fruit and vegetable quality. Mango, avocado, apple, tomato, potato, citrus and grapes were selected as the fruits and vegetables for study due to their world-wide consumption. Disease warning systems for predicting pathogens and insects on farms during fruit and vegetable production are commonly used for all the crops and are available where meteorological stations are present. It can be seen that these disease risk systems are being slowly replaced by remote sensing monitoring in developed countries. Satellite images have reduced their temporal resolution, but are expensive and must become cheaper for their use world-wide. In the last 30 years, a lot of research has been carried out in non-destructive sensors for food quality. Actually, non-destructive technology has been applied for sorting high quality fruit which is desired by the consumer. The sensors require algorithms to work properly; the most used being discriminant analysis and training neural networks. New algorithms will be required due to the high quantity of data acquired and its processing, and for disease warning strategies for disease detection.

On the other hand, data quality is very important for the Accounting Information Systems’ (AIS success, where AIS is a computer-based system that processes financial data and supports the decision making processes inside the organization. There are empirical evidences showing that data quality level in AIS has been and will always be problematic. Their interrelationship is dependant of several factors, including technical capacities or even the level of teamwork in an organization. This paper tries to analyze the actual performance of the factors influencing in the process of data quality in AIS used from organizations in Albania. The results will be compared with state-of-art literature review regarding the factors perceived as critical factors in ensuring data quality in AIS, giving way to some important concluding remarks.

    ENGLISH ABSTRACT: To develop high quality products, a designer has to consider various influential factors, one of which is ergonomics. And to fashion a specific product for the user, a designer needs expert knowledge of the user’s requirements. However, expert knowledge can also be accessed through an intelligent advisory system for ergonomic design support. The effectiveness of such an expert system depends mainly on the quality of the knowledge base and on the appropriateness of the system's inference engine. Data for the system’s knowledge base can be collected in different ways. One approach is to study relevant projects to collect appropriate ergonomic solutions; another is to recognise bottlenecks in ergonomic design. This paper presents a case study of the design of an actual chainsaw – with emphasis on ergonomic design solutions – that can be transformed into ergonomic design recommendations. At the end of the paper, an application of one of the derived recommendations within the knowledge base of the intelligent advisory system is presented.

    It has been acknowledged that females exhibit more smiling behaviors than males, but there has been little attention to this gender difference in the courtroom. Although both male and female witnesses exhibit smiling behaviors, there has been no research examining the subsequent effect of gender and smiling on witness credibility. This study used naturalistic observation to examine smiling behaviors and credibility in actual witnesses testifying in court. Raters assessed the smiling behaviors and credibility (as measured by the Witness Credibility Scale) of 32 male and female witnesses testifying in trials in a mid-sized Southern city. "Credibility raters" rated the perceived likeability, trustworthiness, confidence, knowledge, and overall credibility of the witnesses using the Witness Credibility Scale. "Smile raters" noted smiling frequency and types, including speaking/expressive and listening/receptive smiles. Gender was found to affect perceived trustworthiness ratings, in which male witnesses were seen as more trustworthy than female witnesses. No significant differences were found in the smiling frequency for male and female witnesses. However, the presence of smiling was found to contribute to perceived likeability of a witness. Smiling female witnesses were found to be more likeable than smiling male and non-smiling female witnesses. Copyright © 2014 John Wiley & Sons, Ltd.

  14. Actual development of the chenier coast of suriname (South America)

    Science.gov (United States)

    Augustinus, Pieter G. E. F.

    1980-04-01

    The Holocene coastal plain of Suriname is a chenier plain. Its actual sedimentological development has been studied during three field-work periods (1966, 1967/1968, 1972). Clay is the predominant sediment in this low- to medium-energy environment. It accumulates in extensive shoreface-attached mudflats (sometimes considered as giant mudwaves), which migrate continuously to the west due to deposition of slingmud at their west side and simultaneous erosion of the east side. In between the mudflats cheniers may develop. Thin-section analysis of the clay deposits revealed that they are built up of an alternation of thick clayey laminae and thin laminae of silt and fine sand. The clayey laminae chiefly show a unistrial plasmic fabric. Disturbaces in the upper zone are caused by bioturbation. Two types of cheniers can be distinguished. One type contains fine sand which has been winnowed out of the pelite deposits. Since this sand is brought from the shelf the chenier formation begins at approximately mean low-water level. Longshore bars are formed and these are driven shoreward by wave action. The other type is built up of medium to coarse sand supplied by a local river. It is transported westward by beachdrift in a narrow zone around the mean high-water line. These cheniers develop therefore at or just above the mean high-tide level. The sedimentary structures of both types of cheniers have many characteristics in common. However, each type also has its own distinct features.

    Full Text Available Los trastornos de personalidad representan hoy día una de las áreas de mayor desafío para la psicología científica. Aunque los principales sistemas de clasificación de la psicopatología (DSM-IV y CIE-10 les dedican un considerable espacio, son, quizás, unos de los grupos de síndromes más desconocidos a todos los niveles: epidemiología, etiología, evaluación, tratamiento, etc. En el breve trabajo que aquí presentamos intentamos describir brevemente diversos aspectos de uno de los trastornos de personalidad más representativos actualmente: el trastorno límite de la personalidad (TLP. A pesar de que este síndrome comparte con el resto de los trastornos de personalidad una escasez de conocimiento, es, probablemente, uno de los más investigados y sobre el que se han desarrollado una variedad de terapias cognitivo-conductuales. A lo largo de este trabajo planteamos también algunas de las controversias actuales más candentes y resaltamos la necesidad de una mayor y más sistematizada investigación sobre el TLP.

    Full Text Available El glaucoma es la principal causa de ceguera no reversible en el mundo, afectando al 2% de la población. Actualmente se considera una neuropatía óptica, donde la presión intraocular juega un rol fundamental en la patogenia y las características del daño óptico producido. Con el tratamiento actual, se busca prevenir el daño en la estructura del nervio óptico, para preservar el campo visual, persiguiendo mantener la calidad de vida del paciente. Existen nuevos métodos imaginológicos que junto al examen clínico y campo visual, predicen daño y avance de enfermedad. Se incluyen en la comprensión de la patología la apoptosis y el concepto de neuroprotección. Nuevos fármacos buscan mantener una adecuada reducción en la presión intraocular sin fluctuaciones, evitando efectos adversos y mejorando la adherencia al tratamiento. Nuevas herramientas terapéuticas como la trabeculoplastía selectiva láser y nuevas cirugías como el implante de tubos de drenaje, aumentan las posibilidades de evitar la ceguera por glaucoma.

    Worldwide polychlorinated biphenyls (PCBs) pollution is due to complex mixtures with high number of congeners, making the determination of total PCBs in the environment an open challenge. Because the bulk of PCBs production was made of Aroclor mixtures, this analysis is usually faced by the empirical mixture identification via visual inspection of the chromatogram. However, the identification reliability is questionable, as patterns in real samples are strongly affected by the frequent occurrence of more than one mixture. Our approach is based on the determination of a limited number of congeners chosen to enable objective criteria for Aroclor identification, summing up the advantages of congener-specific analysis with the ones of total PCBs determination. A quantitative relationship is established between congeners and any single mixture, or mixtures combination, leading to the identification of the actual contamination composition. The approach, due to its generality, allows the use of different sets of congeners and any technical mixture, including the non-Aroclor ones. The results confirm that PCB environmental pollution in northern Italy is based on Aroclor. Our methodology represents an important tool to understand the source and fate of the PCBs contamination.

  18. Assisted suicide and euthanasia.

    2013-01-01

    Several countries have adopted laws that regulate physician assistance in dying. Such assistance may consist of providing a patient with a prescription of lethal medication that is self-administered by the patient, which is usually referred to as (physician) assistance in suicide, or of administering lethal medication to a patient, which is referred to as euthanasia. The main aim of regulating physician assistance in dying is to bring these practices into the open and to provide physicians with legal certainty. A key condition in all jurisdictions that have regulated either assistance in suicide or euthanasia is that physicians are only allowed to engage in these acts upon the explicit and voluntary request of the patient. All systems that allow physician assistance in dying have also in some way included the notion that physician assistance in dying is only accepted when it is the only means to address severe suffering from an incurable medical condition. Arguments against the legal regulation of physician assistance in dying include principled arguments, such as the wrongness of hastening death, and arguments that emphasize the negative consequences of allowing physician assistance in dying, such as a devaluation of the lives of older people, or people with chronic disease or disabilities. Opinion polls show that some form of accepting and regulating euthanasia and physician assistance in suicide is increasingly supported by the general population in most western countries. Studies in countries where physician assistance in dying is regulated suggest that practices have remained rather stable in most jurisdictions and that physicians adhere to the legal criteria in the vast majority of cases.

    This report describes the Licensing Support Network (LSN) Assistant--a set of tools for categorizing e-mail messages and documents, and investigating and correcting existing archives of categorized e-mail messages and documents. The two main tools in the LSN Assistant are the LSN Archive Assistant (LSNAA) tool for recategorizing manually labeled e-mail messages and documents and the LSN Realtime Assistant (LSNRA) tool for categorizing new e-mail messages and documents. This report focuses on the LSNAA tool. There are two main components of the LSNAA tool. The first is the Sandia Categorization Framework, which is responsible for providing categorizations for documents in an archive and storing them in an appropriate Categorization Database. The second is the actual user interface, which primarily interacts with the Categorization Database, providing a way for finding and correcting categorizations errors in the database. A procedure for applying the LSNAA tool and an example use case of the LSNAA tool applied to a set of e-mail messages are provided. Performance results of the categorization model designed for this example use case are presented.

    2015-01-01

    Objective To study patients’ acceptance of corticotomy-assisted orthodontics as a treatment option. Methods Adult patients seeking orthodontic treatment were asked to complete two sets of questionnaires; the first set included questions about age, sex, and level of education and general questions about orthodontic treatment; and the second set was related to the corticotomy-assisted orthodontics. Before answering the corticotomy questions, a brief description of the clinical procedure was explained and photographs of an actual procedure were shown. Results A total of 150 subjects were approached and 129 (86%) agreed to answer the questionnaires (72 male and 57 female patients). Of these, only 3.1% did hear about corticotomy and 7.8% selected corticotomy instead of extraction. Fear from the surgery (53.2%) was the most frequent reason for not selecting corticotomy followed by fear from pain (36.9%). The acceptance of corticotomy between males and females was similar. No relationship was found between the level of education and prior knowledge of the procedure, P=0.857. Prior knowledge about corticotomy was not a factor in selecting it as a treatment option (P=0.556) to reduce the treatment time (P=0.427). Conclusion The acceptance of corticotomy-assisted orthodontics as a treatment option was low. Fear from the surgery was the main reason for not selecting it. The acceptance of corticotomy-assisted orthodontics was not related to patient’s level of education or sex. PMID:26316719

  1. Evaluation of extrapolation methods for actual state expenditures on health care in Russian Federation

    Full Text Available Forecasting methods, extrapolation ones in particular, are used in health care for medical, biological and clinical research. The author, using accessible internet space, has not met a single publication devoted to extrapolation of financial parameters of health care activities. This determined the relevance of the material presented in the article: based on health care financing dynamics in Russia in 2000–2010 the author examined possibility of application of basic perspective extrapolation methods - moving average, exponential smoothing and least squares. It is hypothesized that all three methods can equally forecast actual public expenditures on health care in medium term in Russia’s current financial and economic conditions. The study result was evaluated in two time periods: within the studied interval and a five-year period. It was found that within the study period all methods have an average relative extrapolation error of 3–5%, which means high precision of the forecast. The study shown a specific feature of the least squares method which were gradually accumulating results so their economic interpretation became possible only in the end of the studied period. That is why the extrapolating results obtained by least squares method are not applicable in an entire study period and rather have a theoretical value. Beyond the study period, however, this feature was found to be the most corresponding to the real situation. It was the least squares method that proved to be the most appropriate for economic interpretation of the forecast results of actual public expenditures on health care. The hypothesis was not confirmed, the author received three differently directed results, while each method had independent significance and its application depended on evaluation study objectives and real social, economic and financial situation in Russian health care system.

    The value of collaborative, case-based, and problem-based learning has received increased attention in recent years. Several studies have documented veterinary staff and students' generally positive feedback on group learning activities, but one largely unaddressed question is how students actually learn from each other. This study examined how second-year veterinary students learned from each other during a collaborative, case-based learning project. Data were students' written reflections on their learning in the veterinary course and the specific learning experience, and a matched pre- and post-task questionnaire. Consistent with prior research describing veterinary students as individualistic learners, only a third of students spontaneously mentioned learning from each other as one of their most effective strategies. However, when prompted to describe a time when they felt that group members were really learning from each other, students reported highly valuable collaborative learning processes, which they explicitly linked to learning and understanding benefits. Questionnaire data were consistent, showing that students became more positive toward several aspects of the activity as well as toward group work in general. One unexpected finding was the lack of a relationship between students' self-evaluation of their learning and how well group members knew each other. These findings provide strong support for the educational value of collaborative, case-based learning. In light of other research evidence (using observation data) that the amount of time students actually engage in high-level collaborative processes may be rather limited, this article points to the need for veterinary teachers to better prepare students for group learning activities.

    Ecosystem services mapping and modeling has focused more on supply than demand, until recently. Whereas the potential provision of economic benefits from ecosystems to people is often quantified through ecological production functions, the use of and demand for ecosystem services has received less attention, as have the spatial flows of services from ecosystems to people. However, new modeling approaches that map and quantify service-specific sources (ecosystem capacity to provide a service), sinks (biophysical or anthropogenic features that deplete or alter service flows), users (user locations and level of demand), and spatial flows can provide a more complete understanding of ecosystem services. Through a case study in Puget Sound, Washington State, USA, we quantify and differentiate between the theoretical or in situ provision of services, i.e., ecosystems’ capacity to supply services, and their actual provision when accounting for the location of beneficiaries and the spatial connections that mediate service flows between people and ecosystems. Our analysis includes five ecosystem services: carbon sequestration and storage, riverine flood regulation, sediment regulation for reservoirs, open space proximity, and scenic viewsheds. Each ecosystem service is characterized by different beneficiary groups and means of service flow. Using the ARtificial Intelligence for Ecosystem Services (ARIES) methodology we map service supply, demand, and flow, extending on simpler approaches used by past studies to map service provision and use. With the exception of the carbon sequestration service, regions that actually provided services to people, i.e., connected to beneficiaries via flow paths, amounted to 16-66% of those theoretically capable of supplying services, i.e., all ecosystems across the landscape. These results offer a more complete understanding of the spatial dynamics of ecosystem services and their effects, and may provide a sounder basis for economic

    An investigation of several image reconstruction methods for robot-assisted ultrasound (US) tomography setup is presented. In the robot-assisted setup, an expert moves the US probe to the location of interest, and a robotic arm automatically aligns another US probe with it. The two aligned probes can then transmit and receive US signals which are subsequently used for tomographic reconstruction. This study focuses on reconstruction of the speed of sound. In various simulation evaluations as well as in an experiment with a millimeter-range inaccuracy, we demonstrate that the limited data provided by two probes can be used to reconstruct pixel-wise images differentiating between media with different speeds of sound. Combining the results of this investigation with the developed robot-assisted US tomography setup, we envision feasibility of this setup for tomographic imaging in applications beyond breast imaging, with potentially significant efficacy in cancer diagnosis.

    A high sensitive and high stable remote photoelectric receiver has been developed to reduce noise and phase delay drift caused by thermal pollution and environmental interference. The phase delay drift model is analyzed and built based on a traditional photoelectric receiver. According to the model, a new mechanical isolation structure and a temperature control system are designed to keep the photoelectric receiver in a low constant temperature. Comparison experiments with traditional bias voltage compensation method and temperature control method are carried out between photoelectric receivers. The results verify that the output voltage fluctuation of photoelectric receiver used is reduced by 65% while the phase drift between measurement and reference photoelectric receivers decreases from 1.05° to 0.02°.

    A thermal analysis of the Omnium-G receiver is presented and the technique is shown to be generally applicable to solar thermal receivers utilizing a directly heated thermal mass. The thermal loss coefficient, including reradiation losses, is calculated and shown to agree quite well with the experimentally measured thermal loss coefficient. The rate of heat transfer to the working fluid is also analyzed and the analysis is used to show that the Omnium-G receiver is well matched to the water/steam working fluid because the steam outlet temperature is almost the same as the receiver temperature. A general procedure for calculating receiver performance is presented. With this procedure, the energy delivery to any working fluid, the delivered temperature of the working fluid, and the pressure drop through the receiver can be determined. An example of the calculation is also presented.

Desde su consolidación institucional en la segunda post-guerra mundial, su legitimidad,eficiencia y justicia se han cuestionado constantemente. En estos últimos meses, su incapacidad para prever y evitar crisis como la actual se ha criticado especialmente. La crisis de la deuda de los años ochenta, el “tequilazo” mexicano de 1994 o la crisisasiática de finales de los años noventa ponen de manifiesto la existencia de elementos que dichas instituciones no han sido capaces de controlar. La cadena de infortunios financieros de los últimos meses lo corrobora y hace necesaria una profunda reflexión en términos económicos, jurídicos y también institucionales.El Fondo Monetario Internacional constituye, junto con el Banco Internacional de Reconstrucción y Fomento, el núcleo del sistema monetario y financiero internacional. Creado por los acuerdos de Bretton Woods en diciembre de 1945, el Fondo debía encargarse en su origen de favorecer la estabilidad financiera y el crecimiento económico de los Estados, poniendo a disposición de éstos sus recursos. Con el paso de los años, su cometido se ha ampliado abarcando cada vez más aspectos como la supervisión de las políticas económicas de los países miembros o la influencia en las políticas macroeconómicas nacionales. Esa extensión de sus facultades va unida, sin lugar a duda, a una creciente responsabilidad por el cumplimiento satisfactorio de su misión.Teniendo esto en cuenta, el actual debate sobre la necesidad de una nueva arquitectura financiera internacional debe ahondar en las fortalezas y debilidades del Fondo, por su papel fundamental en la misma.

    In the following work, we propose an assessment of wind potential in Algeria. The purpose of this study is twofold. First, to draw the attention to the important wind potential in the region of Hassi-R'mel anti v{approx}6m/s. In the previous maps, the wind potential in this region has been underestimated due the fact that it is located between two less windy regions. Second, the actualization of the wind map of Algeria using very recent data stretching from February 2004 to December 2009. This paper is structured in three main parts. First, a stochastic and the cyclic study of the wind behaviors in the site of Hassi-R'mel are proposed. The stochastic study is carried out by fitting the wind speed data to Weibull distribution while the cyclic study is carried out via the use of time-frequency analysis. We have used the time-frequency analyses instead of the traditional Fourier analysis due its ability to follow the spectrum variation with respect to time. As results, it has been found that spectrum wind process enfold many limited interval oscillations. In the second part, we propose to contribute to the actualisation of the wind map in Algeria. In this part, we have considered also the topographical aspect of Algeria. Such consideration is very helpful for understanding the wind potential reparation over the country. Finally, a techno-economical study of a stand along hybrid system (wind/diesel) in the site of Hassi-R'mel is considered. Via this study, it has been found that been found that the site of Hassi-R'mel is very adequate for wind energy conversion systems. (author)

Por ser la explicación de la sensibilidad de la dentina uno de los más complejos problemas de la fisiología y la histología del diente, se exponen los hechos morfológicos y funcionales que apoyan la validez de los mecanismos mencionados. Se concluye que aunque la teoría hidrodinámica tiene una sólida base experimental y es la de mayor aceptación en la actualidad, pudieran estar involucrados en la génesis del dolor dentinal más de una de estas explicaciones probables.A review of the present hypotheses of dentinal sensitivity was carried out. The analysis was centered on the theories of the existance of nerves in dentin, the transfer of nervous impulse through odontoblast and the fluid flow in the dentin. Since the explanation of dentin sensitivity is one of the most complex problems of dental physiology and histology; the morphological and functional aspects that support the validity of the mentioned mechanisms are stated. It is concluded that although the hydrodynamic theory has a sound experimental basis and is widely accepted at present, more than one of these likely theories could be involved in the genesis of dentinal pain.

  17. Ethics in actual surgery. Ethics and organ transplantation.

    Science.gov (United States)

    Eyskens, E

    1994-01-01

    Actual organ transplantation evokes more and more ethical questions. There is scarcity of donor organs. The waiting lists of potential recipients for organ transplantation are steadily growing as is the number of dead among the waiting patients. In Belgium the mortality rate of traffic victims during the first thirty days of hospital admission has been reduced by half. Among this group the number of potential cadaveric donor candidates is further reduced following complications of sustained intensive care. Shortage of cadaveric organs prompts some to select candidates for transplantation with exclusion of those considered responsible for their illness. Some centres incline to reconsider the definition of cerebral death by extending this notion to the irreversibly unconscious and therefore socially dead. Organ donation by living donors opens the way to commercialism specially in case of unrelated living donation. Living donors are often insufficiently informed about their risks and the final outcome of these transplantations. The use of implantable artificial organs should be the solution to many ethical problems. But some experience with the Jarvik heart as a temporary implant increases so far the shortage of donor heart supply and the number of patients on the waiting lists as well. It also excludes patients who became unsuitable for transplantation after complication of the Jarvik implantation. Xenotransplantation is largely under investigation. However, it is out of question that primates, which are threatened already with extinction should act as organ suppliers for mankind. Xenograft organs should be found in animals for food consumption, sufficient in number and more easily accepted as organ donors on ethical ground.

    Beaked whales have mass stranded during some naval sonar exercises, but the cause is unknown. They are difficult to sight but can reliably be detected by listening for echolocation clicks produced during deep foraging dives. Listening for these clicks, we documented Blainville's beaked whales, Mesoplodon densirostris, in a naval underwater range where sonars are in regular use near Andros Island, Bahamas. An array of bottom-mounted hydrophones can detect beaked whales when they click anywhere within the range. We used two complementary methods to investigate behavioral responses of beaked whales to sonar: an opportunistic approach that monitored whale responses to multi-day naval exercises involving tactical mid-frequency sonars, and an experimental approach using playbacks of simulated sonar and control sounds to whales tagged with a device that records sound, movement, and orientation. Here we show that in both exposure conditions beaked whales stopped echolocating during deep foraging dives and moved away. During actual sonar exercises, beaked whales were primarily detected near the periphery of the range, on average 16 km away from the sonar transmissions. Once the exercise stopped, beaked whales gradually filled in the center of the range over 2-3 days. A satellite tagged whale moved outside the range during an exercise, returning over 2-3 days post-exercise. The experimental approach used tags to measure acoustic exposure and behavioral reactions of beaked whales to one controlled exposure each of simulated military sonar, killer whale calls, and band-limited noise. The beaked whales reacted to these three sound playbacks at sound pressure levels below 142 dB re 1 µPa by stopping echolocation followed by unusually long and slow ascents from their foraging dives. The combined results indicate similar disruption of foraging behavior and avoidance by beaked whales in the two different contexts, at exposures well below those used by regulators to define

    Full Text Available La obesidad es una enfermedad crónica multifactorial que constituye un importante problema de salud a nivel mundial, con riesgo cardiovascular asociado y una morbilidad y mortalidad aumentada, además de alterar la calidad de vida de quienes la padecen. En la actualidad, el sobrepeso y la obesidad se consideran tan importantes como otros factores de riesgo clásicos relacionados con la enfermedad coronaria como dislipidemia, hipertensión arterial, diabetes mellitus, marcadores inflamatorios y estado protrombótico. El tejido adiposo no sólo actúa como almacén de moléculas grasas, sino que sintetiza y libera a la sangre numerosas hormonas relacionadas con el metabolismo de principios inmediatos y la regulación de la ingesta. La pérdida de peso puede evitar la progresión de la placa de aterosclerosis y los eventos coronarios agudos en los sujetos obesos. Los objetivos de esta revisión se enmarcan en abordar brevemente la obesidad y su incidencia actual en las enfermedades cardiovasculares, asi como acotar su diagnóstico, clasificación y adecuado manejo. Se concluye que el diagnóstico de obesidad debe incluir mediciones de contenido total y de distribución de la grasa corporal y que los cambios en el estilo de vida que promuevan una dieta equilibrada y ejercicio físico regular deben ser una de las medidas principales en el tratamiento de la obesidad y sus comorbilidades asociadas.

    Full Text Available Comentando la frase de Hegel de que “lo que hasta hoy se ha alcanzado en América es la expresión de una vida extranjera”, se dice que todo imperio intenta repetir en sus colonias el mundo y la vida de la metrópoli. Esta copia se traslada también a la educación. La universidad latinoamericana traída por los españoles pretendía ser una copia de las universidades de Salamanca o Alcalá. Los objetivos, los contenidos, los métodos pedagógicos –memorísticos y repetitivos- eran trasladados al pie de la letra al nuevo mundo que tenía poco que ver con el viejo mundo español. El esfuerzo por repetir lo extranjero produce una mentalidad colonial que se mantiene en la Universidad con el método actual, repetitivo y memorístico de la docencia. También el chauvinismo provinciano que niega todo valor a las ideas que llegan de fuera, es producto de esa mentalidad colonialista. La Universidad ideal será la que, sin dejar de discutir y analizar las ideas y verdades que nos llegan de afuera, crea y produce sus propias ideas y teorías. La que entra en diálogo con las ideas del mundo. Esto se alcanza sólo con la investigación.

    Full Text Available The article presents the overview of linguistic research on gastronomic / gluttony communicative environment as ethnocultural phenomenon from the standpoint of conceptology, discourse study and linguosemiotics. The authors study the linguosemiotic encoding / decoding in the English gastronomic (gluttony discourse. The peculiarities of gastronomic gluttonyms "immersion" into everyday communication are studied. The anglophone ethnicities are revealed and different ways of gluttony texts (including the precedent ones formation are investigated. The linguosemiotic parameters of ethnocultural (anglophone gastronomic coded communication are established, their discursive characteristics are identified. It is determined that in English gastronomic communication, the discursive actualization of ethno-linguocultural code has a dynamic nature; the constitutive features of gastronomic discourse have symbolic (semiotic basics and are connected with such semiotic categories as code, encoding, decoding. It was found that food is semiotic in its origin and represents the cultural code. It was revealed that the semiosis of English gastronomic text is regularly filled with the codes of traditional "English-likeness" (ethnic term by Roland Barthes expressed by gluttonyms. "Nationality" code is detected through the names of products specific to certain areas; national identity of ethnic code also allows highlighting ways of dish garnishing and serving, typical characteristics of particular local preparation methods. The authors analyze the "lingualization" of food images having an ambivalent character, determined, firstly, by food signs (gluttonyms which structure the common space of gastronomic discourse and provide it with ethnic linguocultural food source; secondly, by immerging formed images into a specific ethnic code that is decoded in gastronomic discourse unfolding. The precedent texts accumulate ethnic information supplying adequate gastronomic worldview

    Differences in actual transpiration (ETa) of banana plants were quantified in a lysimeter experiment. ETA was computed using instantaneous data from two weighing lysimeters and compared to PM (Penman-Monteith) model for ETa. Two critical problems were faced in this test. A) Estimating canopy and aerodynamic resistances ("rc" and "ra" respectively ) and B) converting the lysimeter changes in water volume ( LYv cm3 ) to ETa length units ( cm ). The two unknowns " rc" and "ra" were obtained from continuous measurements of the differences between canopy and air temperature (Tc - Ta). This difference was established by means of the infrared thermometry which was followed by numerical and analytical calculation of ETa using the modification suggested by R. Jackson to the PM model. The conversion of lysimeter volumetric units (LYv) to ETa length units was derived from the slope of cumulative LYv/ETa. This relationship was significantly linear (r2=0.97and 0.98.). Its slope was interpreted as "evaporating leaf area" which accounted for 1.8E4 cm2 in lysimeter 1 and 2.3E4 cm2.in lysimeter 2 . The comparison between LYv and PM model was acceptable even under very low ETa. The average of two lysimeters was 1.1mm/day (1.4 mm/day , LYv 1 and 0.8 LYv 2) while ETa calculated on the basis of PM model was 1.2 mm/day. It was concluded that although lysimeters are most accurate systems to measure ETa one of its disadvantages ( beside the high cost) is the volumetric output that in many cases should be supported by a one dimensional energy balance system. The PM model was found to be a reliable complementary tool to convert lysimeters volumetric output into conventional length units of ETa.

  5. Are presolar dust grains from novae actually from supernovae?

    Science.gov (United States)

    2005-05-01

    Meteorites contain presolar stardust grains that formed in prior generations of stars and exhibit large isotopic anomalies reflecting the nuclear processes that occurred in their individual parent stars. RGB and AGB stars and supernovae are well established as sources of many of these grains. Novae have been proposed as sources for a few SiC and graphite grains with low 12}C/{13C and 14}N/{15N ratios and unusual Si isotopic ratios (Amari et al., ApJ, 551, 1065). We have found three SiC grains from the Murchison meteorite with C and N isotopic ratios similar to the previously-reported putative nova grains. However, the isotopic signatures of Si, Ca, Al and Ti in one of the grains (334-2) clearly indicate a supernova origin, especially excess 28Si correlated with excess 44Ca. The latter signature is attributable to in situ decay of (half-life=50yr) 44Ti. Another 13C- and 15N-rich grain (151-4) has a large 47Ti enrichment. This signature is not expected for nova nucleosynthesis. Thus, the new isotopic data raise the possibility that the grains previously reported to have formed in novae actually formed in supernovae, and that novae have not left a record in the presolar grain populations that have been so far studied. Moreover, the results in grain 334-2 indicate that supernovae contain regions highly enriched in both 13C and 15N. This is not predicted by current models but may bear on the cosmic origin of 15N. This work was funded in part by NASA.

  6. Beaked whales respond to simulated and actual navy sonar.

    Directory of Open Access Journals (Sweden)

    Peter L Tyack

    Full Text Available Beaked whales have mass stranded during some naval sonar exercises, but the cause is unknown. They are difficult to sight but can reliably be detected by listening for echolocation clicks produced during deep foraging dives. Listening for these clicks, we documented Blainville's beaked whales, Mesoplodon densirostris, in a naval underwater range where sonars are in regular use near Andros Island, Bahamas. An array of bottom-mounted hydrophones can detect beaked whales when they click anywhere within the range. We used two complementary methods to investigate behavioral responses of beaked whales to sonar: an opportunistic approach that monitored whale responses to multi-day naval exercises involving tactical mid-frequency sonars, and an experimental approach using playbacks of simulated sonar and control sounds to whales tagged with a device that records sound, movement, and orientation. Here we show that in both exposure conditions beaked whales stopped echolocating during deep foraging dives and moved away. During actual sonar exercises, beaked whales were primarily detected near the periphery of the range, on average 16 km away from the sonar transmissions. Once the exercise stopped, beaked whales gradually filled in the center of the range over 2-3 days. A satellite tagged whale moved outside the range during an exercise, returning over 2-3 days post-exercise. The experimental approach used tags to measure acoustic exposure and behavioral reactions of beaked whales to one controlled exposure each of simulated military sonar, killer whale calls, and band-limited noise.

    2006-01-01

    Digital receivers have become more and more popular in radar, communication, and electric warfare for the advantages compared with their analog counterparts. But conventional digital receivers have been generally considered impractical for bandwidth greater than several hundreds MHz. To extend receiver bandwidth, decrease data rate and save hardware resources, three novel structures are proposed. They decimate the data stream prior to mixing and filtering, then process the multiple decimated streams in parallel at a lower rate. Consequently it is feasible to realize wideband receivers on the current ASIC devices. A design example and corresponding simulation results are demonstrated to evaluate the proposed structures.

    2003-01-01

    Maximum entropy deconvolution is presented to estimate receiver function, with the maximum entropy as the rule to determine auto-correlation and cross-correlation functions. The Toeplitz equation and Levinson algorithm are used to calculate the iterative formula of error-predicting filter, and receiver function is then estimated. During extrapolation, reflective coefficient is always less than 1, which keeps maximum entropy deconvolution stable. The maximum entropy of the data outside window increases the resolution of receiver function. Both synthetic and real seismograms show that maximum entropy deconvolution is an effective method to measure receiver function in time-domain.

  12. Nursing process approach improves receivables management.

    Science.gov (United States)

    Dias, K; Stockamp, D

    1992-09-01

    The "nursing process" is a systematic decision-making approach to problem solving based on open-system theory. This theory assumes that there is an on-going interchange between all system components. Components cannot be viewed in isolation, because decisions regarding one component will affect other components. Receivables management is similar to the nursing process, in that it involves constant diagnosis, assessment, and intervention in the work in process during all phases of the receivables cycle. In experiments that applied the nursing process concept to the management of accounts receivable in several hospitals, gross days in accounts receivable were reduced and cash flow was increased.

    One of the major problems in solar external receivers is tube overheating, which accelerates the risk of receiver failure. It can be solved implementing receivers with high number of panels. However, it exponentially increases the pressure drop in the receiver and the parasitic power consumption of the Solar Power Tower (SPT), reducing the global efficiency of the SPT. A new concept of solar external receiver, named variable velocity receiver, is able to adapt their configuration to the different flux density distributions. A set of valves allows splitting in several independent panels those panels in which the wall temperature is over the limit. It increases the velocity of the heat transfer fluid (HTF) and its cooling capacity. This receiver does not only reduce the wall temperature of the tubes, but also simplifies the control of the heliostat field and allows to employ more efficient aiming strategies. In this study, it has been shown that variable velocity receiver presents high advantages with respect to traditional receiver. Nevertheless, more than two divisions per panels are not recommendable, due to the increment of the pressure drop over 70 bars. In the design point (12 h of the Spring Equinox), the use of a variable number of panels between 18 and 36 (two divisions per panel), in a SPT similar to Gemasolar, improves the power capacity of the SPT in 5.7%, with a pressure drop increment of 10 bars. Off-design, when the flux distribution is high and not symmetric (e.g. 10-11 h), the power generated by the variable velocity receiver is 18% higher than the generated by the traditional receiver, at these hours the pressure drop increases almost 20 bars.

    Robotic surgery has evolved over the last decade to compensate for limitations in human dexterity. It avoids the need for a trained assistant while decreasing error rates such as perforations. The nature of the robotic assistance varies from voice activated camera control to more elaborate telerobotic systems such as the Zeus and the Da Vinci where the surgeon controls the robotic arms using a console. Herein, we report the first series of robotic assisted colectomies in Ireland using a voice activated camera control system.

    2013-01-01

    With the advent of ubiquitous computing there are two design parameters of wireless communication devices that become very important: power efficiency and production cost. Compressive sensing enables the receiver in such devices to sample below the Shannon-Nyquist sampling rate, which may lead...... to a decrease in the two design parameters. This paper investigates the use of Compressive Sensing (CS) in a general Code Division Multiple Access (CDMA) receiver. We show that when using spread spectrum codes in the signal domain, the CS measurement matrix may be simplified. This measurement scheme, named...... Compressive Spread Spectrum (CSS), allows for a simple, effective receiver design. Furthermore, we numerically evaluate the proposed receiver in terms of bit error rate under different signal to noise ratio conditions and compare it with other receiver structures. These numerical experiments show that though...

    A new GPS receiver concept and design are presented to meet the high dynamic and low volume requirements for range applications in missiles and drones. The receiver has the potential to satisfy all range requirements with one basic receiver, which has significant potential economic benefit over the alternate approach of using a family of receivers, each tailored for specific applications. The main new concept is to use approximate maximum likelihood estimates of pseudo range and range-rate, rather than tracking with carrier phase locked loops and code delay locked loops. Preliminary analysis indicates that receivers accelerating at 50 g or more can track with position errors due to acceleration of approximately 0.2 m/g, or 10 m at 50 g. Implementation is almost entirely digital to meet the low volume requirements.

    This article describes the development and randomized evaluation of a tailored nutrition education CD-ROM program for participants in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) in North Carolina. After randomization to intervention or control groups, participants completed a baseline survey and were resurveyed immediately after program use and 1 to 2 months postintervention. Two WIC clinics in central North Carolina. A total of 307 respondents to the follow-up survey (response rate 74.8%) comprised the study sample. Participants were female (96%), 20% were pregnant, and 50% were minorities (African American and other). The interactive CD-ROM consisted of a targeted video soap opera, dietary assessment, and individually tailored dietary feedback and strategies for change. Measures included total fat and fruit and vegetable intake, knowledge of low-fat and infant feeding choices, self-efficacy, and stages of change. Descriptive statistics assessed baseline comparability of study groups; analysis of covariance and F tests were used to assess program effects at follow-up. INTERVENTION group members increased self-efficacy (P <.01) and scored significantly higher (P <.05) on both low-fat and infant feeding knowledge compared with controls. No differential effect was observed for dietary intake variables. The findings suggest that one dose of an interactive CD-ROM program can impact mediators of dietary change but may be insufficient to change behavior.

    Recent advances in effective antimicrobial prophylactic strategies have led to a decline in the incidence of opportunistic infections in liver transplant recipients.However, morbidity and mortality due to infectious diseases remain as major problems. Bacterial infections occurring early after transplant are mainly related to the technical aspects of the procedure. By contrast,after the first postoperative days and beyond, the nature and variety of infectious complications change.Opportunistic bacterial infections are uncommon after 6 mo in patients receiving stable and reduced maintenance doses of immunosuppression with good graft function and little is documented about these cases in the literature. Transplant recipients may be more susceptible to some pathogens, such as the Nocardia species, Legionella species, Listeria monocytogenes , Mycoplasma species, Salmonella species or Rhodococcus equi. Respiratory infections due to capsulated bacteria, such as Streptococcus pneumoniae and Haemophilus influenza, can be lifethreatening if not promptly treated in this population.These late bacterial infections may be very difficult to recognize and treat in this population. In this article,we review what has been described in the literature with regards to late bacterial infections following liver transplantation.

    To establish the proportion of cytology samples sent to a commercial veterinary laboratory that yields diagnostically useful information in the context of current use and perceptions of cytology. Nine hundred and forty-five cytology submissions were retrospectively collected and categorised according to diagnostic utility. A survey into the use and perceptions of cytology was distributed at the British Small Animal Veterinary Association Congress 2008. A specific diagnosis was reached in 23.1 per cent of samples and a cytological diagnosis in 35.3 per cent. 22.4 per cent of samples yielded some useful information, but 19.2 per cent were unacceptable. Seventy-four participants in the survey took an average of 3.9 cytological samples per week, of which they examined 27.0 per cent in-house only, 21.6 per cent in-house before sending to an external laboratory and 51.4 per cent were sent externally without prior examination. "To obtain a definitive diagnosis" was the principal reason cited for performing cytology. Results suggest that cytology is underused and may be applied in an inappropriate context in the UK. It is hoped that illustrating the diagnostic outcome of samples received by a commercial laboratory will encourage increased, appropriate use of cytology.

    Animal-assisted therapy is an emerging complementary strategy with an increasing presence in the literature. Limited studies have been conducted with children, particularly those with life-threatening and life-limiting conditions. Although outcomes show promise in decreasing suffering of children receiving palliative care services, more work is needed to validate evidence to support implementation of animal-assisted therapy with this vulnerable population.

    2006-06-01

    To document the fact that differences in the treatment received by health services users in Mexico are mainly dependent on the type of provider, regardless of the users' socioeconomic status. The data were obtained by means of a survey of 18 018 users who visited 73 health services in 13 states within Mexico. They were asked to grade the way the institution had performed in seven of the eight domains that define appropriate user treatment (autonomy, confidentiality, communication, respectful manner, condition of basic facilities, access to social assistance networks, and free user choice). The questionnaire included some vignettes to help determine user expectations. A composite ordinal probit model was applied; the perception of quality in connection with each of the appropriate treatment domains was the independent variable, whereas gender, educational level, age, type of provider, and user expectations were used as control variables. The type of provider was the main factor that determined users' perceptions regarding the treatment they received when visiting health services in Mexico. Institutions belonging to the social security system performed the worst, while the services provided under the program targeting the rural population (IMSS Oportunidades) received the highest scores. Overall, the domain that was most highly ranked was respectful manner, whereas the lowest score was given to the ability to choose the provider. Men felt they had been able to communicate better than women, while respectful manner, communication, and social support showed a significant negative association with educational level (P < 0.05). Differences were noted in the way different public health service providers in Mexico treat their users, regardless of the latter's socioeconomic status. Social security system providers showed the greatest deficiencies in this respect. Respectful manner was the domain that received the highest scores in the case of all providers. Organizational

    The objective of this preliminary study was to evaluate the perceptions of internationally deployed Disaster Medical Assistance Team (DMAT) personnel regarding the psychosocial support needs of these teams. The DMAT questionnaire was sent to 34 members of Australian medical teams involved in deployments to the 2004 Southeast Asian tsunami and the 2006 Java earthquake. Twenty personnel (59%) completed this survey, which reviewed key deployment stressors, specific support strategies, and the support needs of team members, their families, and team leaders. A key aspect of the survey was to determine whether the perceived psychosocial needs would be supported best within with existing provisions and structures, or if they would be enhanced by further provisions, including the deployment of mental health specialists. There was strong support for brief reviews of stress management strategies as part of the pre-deployment briefing, and access to written stress management information for both team members and their families. However, more comprehensive provisions, including pre-deployment, stress-management training programs for personnel and intra-deployment family support programs, received lower levels of support. The availability of mental health-related training for the team leader role and access to consultation with mental health specialists was supported, but this did not extend to the actual deployment of mental health specialists. In this preliminary study, clear trends toward the maintenance of current mental health support provisions and the role of the DMAT leader were evident. A follow-up study will examine the relationship between team-leader, psychosocial support strategies and team functioning.

    The objective of the study was to compare compliance with and the hypocholesterolaemic effect of lovastatin given once daily as a morning or an evening dose. Twenty-four out-patients with familial hypercholesterolaemia were randomly assigned to receive placebo first, then lovastatin 20 mg, to be taken once daily for 4 weeks, either with the breakfast or evening meal, in a single-blind fashion. Drug compliance was assessed by pill counts and continuous electronic monitoring. Two compliance parameters were evaluated, consumption, defined as percentage of prescribed doses taken, and time compliance, the percentage of total dosing events recorded within defined intervals (6.00-10.00 h, and 17.00-21.00 h), for the morning and evening regimes. Both regimes satisfactorily reduced the total and LDL-cholesterol concentrations, and there was no significant difference in the extent of the reductions. Pill counts overestimated compliance, as revealed by the monitoring method. The times of actual consumption of doses by the patients often differed from that prescribed, predominantly in patients who were told to take the evening dose. Partial time compliance may have confounded the efficacy of the drugs. Electronic compliance monitoring appears to be particularly useful in chronopharmacological studies.

    Data from solid tumor malignancies suggest that actual body weight (ABW) dosing improves overall outcomes. There is the potential to compromise efficacy when chemotherapy dosages are reduced, but the impact of dose adjustment on clinical response and toxicity in hematologic malignancies is unknown. The purpose of this study was to evaluate the outcomes of utilizing a percent of ABW for acute myeloid leukemia (AML) induction chemotherapy dosing. This retrospective, single-center study included 146 patients who received 7 + 3 induction (cytarabine and anthracycline) for treatment of AML. Study design evaluated the relationship between percentage of ABW dosing and complete response (CR) rates in patients newly diagnosed with AML. Percentage of ABW dosing did not influence CR rates in patients undergoing induction chemotherapy for AML (p = 0.83); nor did it influence rate of death at 30 days or relapse at 6 months (p = 0.94). When comparing patients dosed at 90-100 % of ABW compared to ABW, CR rates were not significantly different in patients classified as poor risk (p = 0.907). All favorable risk category patients obtained CR. Preemptive dose reductions for obesity did not influence CR rates for patients with AML undergoing induction chemotherapy and did not influence the composite endpoint of death at 30 days or disease relapse at 6 months.

    Objective The purpose of this study was to explore an objective measure to assess actual body shape of children and adolescents in China. Methods Based on the Chinese National Survey on Student’s Constitution and Health (CNSSCH) in 2005, 210 927 children and adolescents' (7-18 years) body height, body weight, chest circumference, sitting height, chest circumference-height ratio, chest circumference-sitting height ratio, chest circumference-low limb ratio, and sitting height-low limb ratio measurements were used to develop an objective measure by using transformation variables and explored factor analysis (EFA). Discrimination power of the objective measure was evaluated based on BMI reference and Receiver Operating Characteristic curves (ROC). Results The objective measure included four dimensions scores:transverse dimension (TD) indicating weight and chest circumference; length dimension (LD) indicating height and sitting height;transverse-length ratio dimension (TLD) indicating chest circumference-height ratio, chest circumference-sitting height and chest circumference-low limb ratio; proportion dimension (PD) indicating sitting height-low limb ratio. The whole dimension (WD) indicating the whole body shape was showed by the average of four dimensions scores. Four dimensions and WD scores were approximately 80 in children and adolescents with normal weight, and higher than those of overweight, obesity, and underweight (all P-values Conclusion The objective measure which included four dimensions was explored, and TD, TLD, and WD had significant discrimination power.

    Introduction Accessibility and assistive products and technologies are needed to ensure the rights of persons with disabilities and older persons. Many developments have been implemented in laws, standards, markets and from the consumers perspective, at international, European and national levels. The real issue is that not all the potential users benefit from the use of assistive products or accessible measures. Discussion Innovative methods are needed to allow all potential users to have real advantage of assistive technologies and accessible and design for all facilities. Best practices will be presented and existing gaps and recommendations will be discussed. Cost-benefits aspects will also be presented. Conclusion In order to get advantages from opportunities of globalization, hard work and responsibilities of all stakeholders are needed, so that assistive products and accessibility reach a whole range of situations and environments and contribute to ensure quality of life in a society for all.

    2014-04-01

    According to the National Registry of Renal Replacement Therapy (RRT), the incidence of chronic kidney disease (end-stage renal disease) and the need of RRT have declined in the last decade renal. One of the reasons for this tendency certainly is transplantation as the best choice. However, transplant procedure has limitations in elderly patients due to the number of comorbidities. This study was designed as retrospective analysis of outcomes in patients treated with peritoneal dialysis for a period of eleven years. Patients were divided into those who had been assisted or unassisted. Out of 100 patients treated with peritoneal dialysis (PD), 77 completed the treatment, including 26 assisted and 51 unassisted patients. Peritonitis was recorded in 20 assisted and 26 unassisted patients. Peritonitis was more common in unassisted patients, who were more frequently lost from PD. Assisted PD could be a good and safe choice of RRT in this special group of patients.

    Clazzer, Federico; Lázaro, Francisco; Plass, Simon

    2016-12-01

    The possibility to detect Automatic Identification System (AIS) messages from low earth orbit (LEO) satellites paves the road for a plurality of new and unexplored services. Besides worldwide tracking of vessels, maritime traffic monitoring, analysis of vessel routes employing big data, and oceans monitoring are just few of the fields, where satellite-aided AIS is beneficial. Designed for ship-to-ship communication and collision avoidance, AIS satellite reception performs poorly in regions with a high density of vessels. This calls for the development of advanced satellite AIS receivers able to improve the decoding capabilities. In this context, our contribution focuses on the introduction of a new enhanced AIS receiver design and its performance evaluation. The enhanced receiver makes use of a coherent receiver for the low signal-to-noise ratio (SNR) region, while for medium to high SNRs, a differential Viterbi receiver is used. Additional novelty of our work is in the exploitation of previously decoded packets from one vessel that is still under the LEO reception range, to improve the vessel detection probability. The assessment of the performance against a common receiver is done making the use of a simple and tight model of the medium access (MAC) layer and the multi-packet reception (MPR) matrix for physical layer (PHY) representation. Performance results show the benefits of such enhanced receiver, especially when it is bundled with successive interference cancellation (SIC).

    Highly sensitive terahertz heterodyne receivers have been mostly single-pixel. However, now there is a real need of multi-pixel array receivers at these frequencies driven by the science and instrument requirements. In this paper we explore various receiver font-end and antenna architectures for use in multi-pixel integrated arrays at terahertz frequencies. Development of wafer-level integrated terahertz receiver front-end by using advanced semiconductor fabrication technologies has progressed very well over the past few years. Novel stacking of micro-machined silicon wafers which allows for the 3-dimensional integration of various terahertz receiver components in extremely small packages has made it possible to design multi-pixel heterodyne arrays. One of the critical technologies to achieve fully integrated system is the antenna arrays compatible with the receiver array architecture. In this paper we explore different receiver and antenna architectures for multi-pixel heterodyne and direct detector arrays for various applications such as multi-pixel high resolution spectrometer and imaging radar at terahertz frequencies.

    2012-01-01

    While much of the current literature on GPS receivers is aimed at those intimately familiar with their workings, this volume summarizes the basic principles using as little mathematics as possible, and details the necessary specifications and circuits for constructing a GPS receiver that is accurate to within 300 meters. Dedicated sections deal with the features of the GPS signal and its data stream, the details of the receiver (using a hybrid design as exemplar), and more advanced receivers and topics including time and frequency measurements. Later segments discuss the Zarlink GPS receiver chip set, as well as providing a thorough examination of the TurboRogue receiver, one of the most accurate yet made. Guiding the reader through the concepts and circuitry, from the antenna to the solution of user position, the book’s deployment of a hybrid receiver as a basis for discussion allows for extrapolation of the core ideas to more complex, and more accurate designs. Digital methods are used, but any analogue c...

    In Precise Point Positioning (PPP), hardware delays at the receiver site (receiver, cables, antenna, …) are always difficult to be separated from the estimated receiver clock parameters. As a result, they are partially or fully contained in the estimated "apparent" clocks and will influence the deterministic and stochastic modelling of the receiver clock behaviour. In this contribution, using three years of data, the receiver clock corrections of a set of high-precision Hydrogen Masers (H-Masers) connected to stations of the ESA/ESOC network and the International GNSS Service (IGS) are firstly characterized concerning clock offsets, drifts, modified Allan deviations and stochastic parameters. In a second step, the apparent behaviour of the clocks is modelled with the help of a low-order polynomial and a known temperature coefficient (Weinbach, 2013). The correlations between the temperature and the hardware delays generated by different types of antennae are then analysed looking at daily, 3-day and weekly time intervals. The outcome of these analyses is crucial, if we intend to model the receiver clocks in the ground station network to improve the estimation of station-related parameters like coordinates, troposphere zenith delays and ambiguities.

  1. Perceived and actual social discrimination: The case of overweight and social inclusion

    Directory of Open Access Journals (Sweden)

    Freda-Marie eHartung

    2013-04-01

    Full Text Available The present study examined the correspondence between perceived and actual social discrimination of overweight people. In total, 77 first-year students provided self-ratings about their height, weight, and perceived social inclusion. To capture actual social inclusion, each participant nominated those fellow students a she/he likes and dislikes and b about whom she/he is likely to hear social news. Students with lower BMI felt socially included, irrespective of their actual social inclusion. In contrast, students with higher BMI felt socially included depending on the degree of their actual social inclusion. Specifically, their felt social inclusion accurately reflected whether they were actually liked/disliked, but only when they were part of social news. When not part of social news, they also showed insensitivity to their actual social inclusion status. Thus, students with a lower BMI tended to be insensitive, while students with a higher BMI showed a differential sensitivity to actual social discrimination.

    Full Text Available This paper has three goals: (1 to identify intended and actual uses of ICT in five different didactic sequences; (2 to compare the intended and actual uses of ICT in the sequences; (3 to investigate how the actual uses of ICT in the sequences transform and improve teaching and learning in those classrooms. The didactic sequences were studied using an observational, case study approach. Four main actual uses of ICT were identified. These actual uses differ from the intended uses. The identified actual uses did not involve so much transformation of classroom practice as it was intended. These results are discussed from a socio-cultural view. The need of analysing actual uses of ICT within the framework of teacher-students joint activity is stressed.

    The present study examined the correspondence between perceived and actual social discrimination of overweight people. In total, 77 first-year students provided self-ratings about their height, weight, and perceived social inclusion. To capture actual social inclusion, each participant nominated those fellow students (a) she/he likes and dislikes and (b) about whom she/he is likely to hear social news. Students with lower Body Mass Index (BMI) felt socially included, irrespective of their actual social inclusion. In contrast, students with higher BMI felt socially included depending on the degree of their actual social inclusion. Specifically, their felt social inclusion accurately reflected whether they were actually liked/disliked, but only when they were part of social news. When not part of social news, they also showed insensitivity to their actual social inclusion status. Thus, students with a lower BMI tended to be insensitive, while students with a higher BMI showed a differential sensitivity to actual social discrimination.

  4. ACTUAL-WASTE TESTING OF ULTRAVIOLET LIGHT TO AUGMENT THE ENHANCED CHEMICAL CLEANING OF SRS SLUDGE

    Energy Technology Data Exchange (ETDEWEB)

    Martino, C.; King, W.; Ketusky, E.

    2012-07-10

    In support of Savannah River Site (SRS) tank closure efforts, the Savannah River National Laboratory (SRNL) conducted Real Waste Testing (RWT) to evaluate Enhanced Chemical Cleaning (ECC), an alternative to the baseline 8 wt% oxalic acid (OA) chemical cleaning technology for tank sludge heel removal. ECC utilizes a more dilute OA solution (2 wt%) and an oxalate destruction technology using ozonolysis with or without the application of ultraviolet (UV) light. SRNL conducted tests of the ECC process using actual SRS waste material from Tanks 5F and 12H. The previous phase of testing involved testing of all phases of the ECC process (sludge dissolution, OA decomposition, product evaporation, and deposition tank storage) but did not involve the use of UV light in OA decomposition. The new phase of testing documented in this report focused on the use of UV light to assist OA decomposition, but involved only the OA decomposition and deposition tank portions of the process. Compared with the previous testing at analogous conditions without UV light, OA decomposition with the use of UV light generally reduced time required to reach the target of <100 mg/L oxalate. This effect was the most pronounced during the initial part of the decomposition batches, when pH was <4. For the later stages of each OA decomposition batch, the increase in OA decomposition rate with use of the UV light appeared to be minimal. Testing of the deposition tank storage of the ECC product resulted in analogous soluble concentrations regardless of the use or non-use of UV light in the ECC reactor.

  5. Measuring the Optical Performance of Evacuated Receivers via an Outdoor Thermal Transient Test: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Modern parabolic trough solar collectors operated at high temperatures to provide the heat input to Rankine steam power cycles employ evacuated receiver tubes along the collector focal line. High performance is achieved via the use of a selective surface with a high absorptance for incoming short-wave solar radiation and a low emittance for outgoing long-wave infrared radiation, as well as the use of a hard vacuum to essentially eliminate convective and conductive heat losses. This paper describes a new method that determines receiver overall optical efficiency by exposing a fluid-filled, pre-cooled receiver to one sun outdoors and measuring the slope of the temperature curve at the point where the receiver temperature passes the glass envelope temperature (that is, the point at which there is no heat gain or loss from the absorber). This transient test method offers the potential advantages of simplicity, high accuracy, and the use of the actual solar spectrum.

    Burhans, R. W.

    1977-01-01

    The limitations of different E-field antenna coupler or preamplifier circuits are presented. All circuits were evaluated using actual Loran or Omega signals. Electric field whip or wire antennas are the simplest types which can be used for reception of VLF signals in the 10 to 100 kHz range. JFET or MOSFET transistors provide impedance transformation and some voltage gain in simple circuits where the power for operating the preamplifier uses the same coaxial cable that feeds the signal back to the receiver. The circuit techniques provide useful alternative methods for Loran-Omega receiver system designers.

    Laparoscopy-assisted surgery for either rectal or gastric cancer has been increasingly performed. However, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is rarely reported in the literature. In our study, 3 cases of patients who received simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer were recorded. The results showed that all 3 patients recovered well, with only 253 minutes of mean operation time, 57 mL of intraoperative blood loss, 5 cm of assisted operation incision, 4 days to resume oral intake, 12 days' postoperative hospital stay, and no complication or mortality. No recurrence or metastasis was found within the follow-up period of 22 months. When performed by surgeons with plentiful experience in laparoscopic technology, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is safe and feasible, with the benefits of minimal trauma, fast recovery, and better cosmetic results, compared with open surgery.

    In this paper, we show how to construct non-binary entanglement-assisted stabilizer quantum codes by using pre-shared entanglement between the sender and receiver. We also give an algorithm to determine the circuit for non-binary entanglement-assisted stabilizer quantum codes and some illustrated examples. The codes we constructed do not require the dual-containing constraint, and many non-binary classical codes, like non-binary LDPC codes, which do not satisfy the condition, can be used to construct non-binary entanglement-assisted stabilizer quantum codes.

    The Validation Demonstration establishes that the high dynamic Global Positioning System (GPS) receiver concept developed at JPL meets the dynamic tracking requirements for range instrumentation of missiles and drones. It was demonstrated that the receiver can track the pseudorange and pseudorange rate of vehicles with acceleration in excess of 100 g and jerk in excess of 100 g/s, dynamics ten times more severe than specified for conventional High Dynamic GPS receivers. These results and analytic extensions to a complete system configuration establish that all range instrumentation requirements can be met. The receiver can be implemented in the 100 cu in volume required by all missiles and drones, and is ideally suited for transdigitizer or translator applications.

  5. Two kinds of physician-assisted death.

    Science.gov (United States)

    den Hartogh, Govert

    2017-08-23

    I argue that the concept 'physician-assisted suicide' covers two procedures that should be distinguished: giving someone access to humane means to end his own life, and taking co-responsibility for the safe and effective execution of that plan. In the first section I explain the distinction, in the following sections I show why it is important. To begin with I argue that we should expect the laws that permit these two kinds of 'assistance' to be different in their justificatory structure. Laws that permit giving access only presuppose that the right to self-determination implies a right to suicide, but laws that permit doctors to take co-responsibility may have to appeal to a principle of mercy or beneficence. Actually this difference in justificatory structure can to some extent be found in existing regulatory systems, though far from consistently. Finally I argue that if one recognizes a right to suicide, as Oregon and other American states implicitly do, and as the European Court of Human Rights has recently done explicitly, one is committed to permit the first kind of 'assistance' under some conditions. © 2017 John Wiley & Sons Ltd.

  9. Inversion of receiver function by wavelet transformation

    吴庆举; 田小波; 张乃铃; 李桂银; 曾融生

    2003-01-01

    A new method for receiver function inversion by wavelet transformation is presented in this paper. Receiver func-tion is expanded to different scales with different resolution by wavelet transformation. After an initial model be-ing taken, a generalized least-squares inversion procedure is gradually carried out for receiver function from low tohigh scale, with the inversion result for low order receiver function as the initial model for high order. Aneighborhood containing the global minimum is firstly searched from low scale receiver function, and will gradu-ally focus at the global minimum by introducing high scale information of receiver function. With the gradual ad-dition of high wave-number to smooth background velocity structure, wavelet transformation can keep the inver-sion result converge to the global minimum, reduce to certain extent the dependence of inversion result on theinitial model, overcome the nonuniqueness of generalized least-squares inversion, and obtain reliable crustal andupper mantle velocity with high resolution.

  10. GPS Receiver Performance Inspection by Wavelet Transform

    Xia Lin-yuan; Liu Jing-nan; Lu Liang-xi

    2003-01-01

    As a powerful analysis tool and the result of contemporary mathematics development, wavelet transform has shown its promising application potentials through the research in the paper. Three aspects regarding GPS receiver performance is tackled: cycle slip detection, receiver noise analysis and receiver channel bias inspection. Wavelet decomposition for double differential observation has demonstrated that this multi-level transform can reveal cycle slips as small as 0.5 cycles without any pre-adjustment processes or satellite orbit information, it can therefore be regarded as a 'geometry free' method. Based on property assumption of receiver noise, signal of noise serial is obtained at the high frequency scale in wavelet decomposition layers. This kind of noise influence on GPSb aseline result can be effectively eliminated by reconstruction process during wavelet reconstruction. Through observed data analysis, the transform has detected a kind of receiver channel bias that has not been completely removed by processing unit of GPS receiver during clock offset resetting operation. Thus the wavelet approach can be employed as a kind of system diagnosis in a generalized point of view.

  11. Efficient receiver tuning using differential evolution strategies

    Science.gov (United States)

    Wheeler, Caleb H.; Toland, Trevor G.

    2016-08-01

    Differential evolution (DE) is a powerful and computationally inexpensive optimization strategy that can be used to search an entire parameter space or to converge quickly on a solution. The Kilopixel Array Pathfinder Project (KAPPa) is a heterodyne receiver system delivering 5 GHz of instantaneous bandwidth in the tuning range of 645-695 GHz. The fully automated KAPPa receiver test system finds optimal receiver tuning using performance feedback and DE. We present an adaptation of DE for use in rapid receiver characterization. The KAPPa DE algorithm is written in Python 2.7 and is fully integrated with the KAPPa instrument control, data processing, and visualization code. KAPPa develops the technologies needed to realize heterodyne focal plane arrays containing 1000 pixels. Finding optimal receiver tuning by investigating large parameter spaces is one of many challenges facing the characterization phase of KAPPa. This is a difficult task via by-hand techniques. Characterizing or tuning in an automated fashion without need for human intervention is desirable for future large scale arrays. While many optimization strategies exist, DE is ideal for time and performance constraints because it can be set to converge to a solution rapidly with minimal computational overhead. We discuss how DE is utilized in the KAPPa system and discuss its performance and look toward the future of 1000 pixel array receivers and consider how the KAPPa DE system might be applied.

    2002-01-01

    We describe herein the cases of 2 patients who had ventricular arrhythmias. In one, a short-term biventricular assist device, the ABIOMED BVS 5000, was placed because the patient had sustained ventricular tachycardia and could not be weaned from cardiopulmonary bypass. Excellent hemodynamic support was maintained for several days while the antiarrhythmic therapy was maximized. Sinus rhythm was restored, and the patient was successfully weaned from the ventricular assist device. However, the substrate for the arrhythmia persisted, and a recurrence, 1 week later, resulted in the patient's death. In the 2nd patient, the use of an implantable left ventricular assist device was successful in temporarily alleviating the ventricular tachycardia associated with ischemic cardiomyopathy. However, after 2 days of device assistance, the patient experienced a recurrence of the tachycardia, which degenerated into ventricular fibrillation with a marked deterioration in the patient's hemodynamics. The arrhythmia persisted despite multiple attempts at external cardioversion, and internal cardioversion and placement of an automatic implantable cardioverter-defibrillator were necessary. This treatment, along with repeated boluses of amiodarone, led to successful suppression of the arrhythmias, and the patient eventually underwent transplantation. The mechanical hemodynamic support of the circulation by ventricular assist devices was effective in supporting these 2 patients who had sustained ventricular arrhythmias.

  18. Millimeter-wave receivers for wireless communications

    Science.gov (United States)

    Overmiller, Brock Morgan

    The modern communications environment is becoming an increasingly crowded place, resulting in rapidly increasing demands on current technology. Military and civilian operations require the ability to locate and decode all communication signals in the environment. However, developments in RADAR (RAdio Detection And Ranging) and communications technology are making it harder to effectively identify and maintain bandwidth usage for everyone. Millimeter waves--waves measured between one millimeter to one centimeter in wavelength--have only recently been explored as a new technology to replace the augment receiver architectures. These small wavelengths introduce many engineering challenges, such as: large atmospheric losses, poor sensitivity, and expensive electronic equipment. With growing developments in Microwave Photonics, low-noise RF amplifiers and high-speed modulators have demonstrated the ability to design RF communication links in the millimeter wave regime to counter such problems. However, despite these developments, toward a cost-effective, spatial division multiplexing (SDM) receiver concept has not proved capable of being implemented as part of the next generation 5G wireless network infrastructure. To this end, we present a novel receiver architecture utilizing an optically addressed phased-array millimeter wave receiver based on optical-upconversion and signal recovery. This receiver is capable of geolocation and spatial multiplexing of multiple Tunable Optically Paired Source (TOPS) communication signals in its scene. Operating at 35 GHz, the receiver up-converts the received RF onto an optical sideband, which, to our advantage, contains all of the frequency, amplitude, and phase information of the received signals. Subsequent optical processing allows routing of the sideband to a free space detector port. Photomixing a coherent optical local oscillator (LO) with the optical sideband performs heterodyne down-conversion to an Intermediate Frequency (IF

    A mobile autonomous humanoid robot is assisting human co-workers at the Johnson Space Center with tool handling tasks. This robot combines the upper body of the National Aeronautics and Space Administration (NASA)/Defense Advanced Research Projects Agency (DARPA) Robonaut system with a Segway(TradeMark) Robotic Mobility Platform yielding a dexterous, maneuverable humanoid perfect for aiding human co-workers in a range of environments. This system uses stereo vision to locate human team mates and tools and a navigation system that uses laser range and vision data to follow humans while avoiding obstacles. Tactile sensors provide information to grasping algorithms for efficient tool exchanges. The autonomous architecture utilizes these pre-programmed skills to form human assistant behaviors. The initial behavior demonstrates a robust capability to assist a human by acquiring a tool from a remotely located individual and then following the human in a cluttered environment with the tool for future use.

    While substantial attention has been paid to the issue of sexual dysfunction in men on chronic dialysis, less is known about this problem in women with end-stage renal disease. We sought to assess sexual dysfunction in women on chronic dialysis and determine whether patients discuss this problem with their providers and receive treatment. We prospectively enrolled women receiving chronic hemodialysis or peritoneal dialysis in Pittsburgh, PA. We asked patients to complete the 19-item Female Sexual Function Index (FSFI) to assess sexual function and a 5-item survey that assessed whether patients had discussed sexual dysfunction with their providers and/or received treatment for this problem in the past. We enrolled 66 patients; 59 (89%) on hemodialysis and 7 (11%) on peritoneal dialysis. All patients completed the FSFI, of whom 53 (80%) had FSFI scores <26.55, consistent with the presence of sexual dysfunction. Of 37 patients who were married or residing with a significant other, 27 (73%) had sexual dysfunction. Among 24 participants who reported having been sexually active over the previous 4 weeks, 11 (46%) had sexual dysfunction. Only 21% of patients with sexual dysfunction had discussed this problem with their gynecologist, renal or primary provider, and 3 (6%) reported having received treatment. Sexual dysfunction is common in women on dialysis, even among patients who are married or residing with a significant other and those who are sexually active. However, few women discuss this issue with their providers or receive treatment.

  3. Receiver-Controlled Multi-Node Cooperation

    Since wireless links in Ad hoc networks are more fragile than those in traditional wireless networks due to route flapping, multi-node cooperation plays an important role in ensuring the quality of service ( QoS) . Based on the authors’ previous work, this paper proposes a receiver-controlled multi-node cooperation routing protocol, known as AODV-RCC. In this protocol, nodes form a cooperation group based on signal power. In a cooperation group, signal power between a partner and a transmitter, as well as signal power between the partner and the receiver, must be larger than the signal power between the transmitter and the receiver. Otherwise, the transmission will not benefit from cooperation. To avoid collision or congestion, each cooperation group only contains one partner. This partner offers both data and ACK cooperative retransmission. Its retransmission time should be shorter than the internal retry time of the transmitter’ s MAC layer, because it is better for the partner to retransmit firstly, as it offers a more reliable cooperative link. In AODV-RCC, it is the receiver that chooses the partner, because the link between the partner and the receiver is the most important. According to our simulation results, AODV-RCC shortens the end-to-end delay and increases the packet delivery ratio.

    Hesler, Jeffrey; Crowe, Thomas

    2011-01-01

    Compact THz receivers with broad bandwidth and low noise have been developed for the frequency range from 100 GHz to 1 THz. These receivers meet the requirements for high-resolution spectroscopic studies of planetary atmospheres (including the Earth s) from spacecraft, as well as airborne and balloon platforms. The ongoing research is significant not only for the development of Schottky mixers, but also for the creation of a receiver system, including the LO chain. The new receivers meet the goals of high sensitivity, compact size, low total power requirement, and operation across complete waveguide bands. The exceptional performance makes these receivers ideal for the broader range of scientific and commercial applications. These include the extension of sophisticated test and measurement equipment to 1 THz and the development of low-cost imaging systems for security applications and industrial process monitoring. As a particular example, a WR-1.9SHM (400-600 GHz) has been developed (see Figure 1), with state-of-the-art noise temperature ranging from 1,000-1,800 K (DSB) over the full waveguide band. Also, a Vector Network Analyzer extender has been developed (see Figure 2) for the WR1.5 waveguide band (500 750 GHz) with 100-dB dynamic range.

    The status of the ongoing Direct Broadcast Satellite-Radio (DBS-R) Receiver Development Task being performed at the Jet Propulsion Laboratory, California Institute of Technology (JPL) is reported. This work is sponsored by the Voice of America/U.S. Information Agency through an agreement with NASA. The objective of this task is to develop, build, test, and demonstrate a prototype receiver that is compatible with reception of digital audio programs broadcast via satellites. The receiver is being designed to operate under a range of reception conditions, including fixed, portable, and mobile, as well as over a sufficiently wide range of bit rates to accommodate broadcasting systems with different cost/audio quality objectives. While the requirements on the receiver are complex, the eventual goal of the design effort is to make the design compatible with low cost production as a consumer product. One solution may be a basic low cost core design suitable for a majority of reception conditions, with optional enhancements for reception in especially difficult environments. Some of the receiver design parameters were established through analysis, laboratory tests, and a prototype satellite experiment accomplished in late 1991. Many of the necessary design trades will be made during the current simulation effort, while a few of the key design options will be incorporated into the prototype for evaluation during the planned satellite field trials.

    Maslow's need hierarchy and model of the self-actualizing personality are reviewed and criticized. The definition of self-actualization is found to be confusing, and the gratification of all needs is concluded to be insufficient to explain self-actualization. Therefore the theory is reconstructed on the basis of a second-order, cognitive-systemic framework. A hierarchy of basic needs is derived from the urgency of perturbations which an autonomous system must compensate in order to maintain i...

    2015-01-01

    We compared imagined versus actual affective and behavioral responses to witnessing a homophobic slur. Participants (N = 72) witnessed a confederate using a homophobic slur, imagined the same scenario, or were not exposed to the slur. Those who imagined hearing the slur reported significantly higher levels of negative affect than those who actually witnessed the slur, and nearly one half of them reported that they would confront the slur, whereas no participants who actually heard the slur confronted it. These findings reveal a discrepancy between imagined and real responses to homophobic remarks, and they have implications for the likelihood that heterosexuals will actually confront homophobic remarks.

  15. Randomized transmit and receive ultrasound tomography

    CERN Document Server

    Clement, Gregory T

    2015-01-01

    A tomographic method is considered that forms images from sets of spatially randomized source signals and receiver sensitivities. The method is designed to allow image reconstruction for an extended number of transmitters and receivers in the presence noise and without plane wave approximation or otherwise approximation on the size or regularity of source and receiver functions. An overdetermined set of functions are formed from the Hadamard product between a Gaussian function and a uniformly distributed random number set. It is shown that this particular type of randomization tends to produce well-conditioned matrices whose pseudoinverses may be determined without implementing relaxation methods. When the inverted sets are applied to simulated first-order scattering from a Shepp-Logan phantom, successful image reconstructions are achieved for signal-to-noise ratios (SNR) as low as 1. Evaluation of the randomization approach is conducted by comparing condition numbers with other forms of signal randomization....

    Wollack, Edward J.

    2011-01-01

    Cryogenically cooled HEMT (High Electron Mobility Transistor) amplifiers find widespread use in radioastronomy receivers. In recent years, these devices have also been commonly employed in broadband receivers for precision measurements of the Cosmic Microwave Background (CMB) radiation. In this setting, the combination of ultra-low-noise and low-spectral-resolution observations reinforce the importance achieving suitable control over the device environment to achieve fundamentally limited receiver performance. The influence of the intrinsic amplifier stability at low frequencies on data quality (e.g., achievable noise and residual temporal correlations), observational and calibration strategies, as well as architectural mitigation approaches in this setting will be discussed. The implications of device level 1/f fluctuations reported in the literature on system performance will be reviewed.

    Full Text Available This work describes the optical and electrical characterization of an integrated optoelectronic receiver. The receiver is composed of a photodiode and a transimpedance amplifier, both fabricated in silicon technology using a 0.8 μm BiCMOS process. The total area occupied by the photodiode is of 10,000 μm2. In a first step, the generated photocurrent of the photodiode is measured for the wavelengths of 780 nm and 830 nm at different levels of optical power. In a second step, the responsivity and quantum efficiency parameters of the photodiode are computed. Finally, an electrical measurement including the transimpedance amplifier is achieved. A potential application for this optoelectronic receiver is on the first optical communications window.

    Full Text Available Universal Asynchronous Receiver Transmitter (UART is the serial communication protocol that is used for data exchange between computer & peripherals. UART is a low velocity, short-distance, low-cost protocol. UART includes three modules which are received, the baud rate generator and transmitter. The UART design with Very High Description Language can be integrated into the Field Programmable Gate Array to achieve stable data transmission and to make system reliable and compact. In the result and simulation part, this project will focus on check the receive data with error free & baud rate generation at different frequencies. Before synthesizing of UART a baud rate generator is incorporated into the system. We use the frequency divider which sets itself to required frequency for the functionality at lower frequency. All modules are designed using VERILOG and implemented on Xilinx Suite development board.

    2008-01-01

    A Bayesian inference learning process for cognitive receivers is provided in this paper. We focus on the particular case of signal detectionas an explanatory example to the learning framework. Under any prior state of knowledge on the communication channel, an information theoretic criterion is presented to decide on the presence of informative data in a noisy wireless MIMO communication. We detail the particular cases of knowledge, or absence of knowledge at the receiver, of the number of transmit antennas and noise power. The provided method is instrumental to provide intelligence to the receiver and gives birth to a novel Bayesian signal detector. The detector is compared to the classical power detector and provides detection performance upper bounds. Simulations corroborate the theoretical results and quantify the gain achieved using the proposed Bayesian framework.

    2016-01-01

    The primary antenna elements and receivers are two of the most important components in a synthesis telescope. Together they are responsible for locking onto an astronomical source in both direction and frequency, capturing its radiation, and converting it into signals suitable for digitization and correlation. The properties and performance of antennas and receivers can affect the quality of the synthesized images in a number of fundamental ways. In this lecture, their most relevant design and performance parameters are reviewed, with emphasis on the current ALMA and VLA systems. We discuss in detail the shape of the primary beam and the components of aperture efficiency, and we present the basics of holography, pointing, and servo control. On receivers, we outline the use of amplifiers and mixers both in the cryogenic front-end and in the room temperature back-end signal path. The essential properties of precision local oscillators (LOs), phase lock loops (PLLs), and LO modulation techniques are also describ...

    A set of measurements performed by the Michigan Tech Sensing and Signal Processing Group on the analog receiver built by the Virginia Polytechnic Institute (VPI) and the Jet Propulsion Laboratory (JPL) for propagation measurements using the Olympus Satellite is described. Measurements of local oscillator (LO) phase noise were performed for all of the LOs supplied by JPL. In order to obtain the most useful set of measurements, LO phase noise measurements were made using the complete VPI receiver front end. This set of measurements demonstrates the performance of the receiver from the Radio Frequency (RF) input through the high Intermediate Frequency (IF) output. Three different measurements were made: LO phase noise with DC on the voltage controlled crystal oscillator (VCXO) port; LO phase noise with the 11.381 GHz LO locked to the reference signal generator; and a reference measurement with the JPL LOs out of the system.

  2. Reflux heat-pipe solar receivers for dish-electric systems

    1988-04-01

    The feasibility of competitive, modular bulk electric power from the sun may be greatly enhanced by the use of a reflux heat pipe receiver to combine a heat engine with a paraboloidal dish concentrator. This combination represents a potential improvement over previous successful demonstrations of dish-electric technology in terms of enhanced performance, lower cost, longer life, and greater flexibility in engine design. In the reflux (i.e., gravity assisted) heat pipe receiver, concentrated solar radiation causes liquid metal (sodium, potassium, or NaK) to evaporate. The vapor flows to the engine interface heat exchanger, where it condenses and releases the latent heat. The condensate is returned to the receiver absorber by gravity (refluxing), and distributed over the surface by gravity and/or capillary forces in a wick lining the receiver. It is essentially an adaptation of heat pipe technology to the peculiar requirements of concentrated solar flux, and provides many advantages over conventional heated tub receiver technology. This overview paper describes the current status and future plans for the U.S. Solar Thermal Program reflux receiver development program at Sandia National Laboratories. Current work includes conventional mesh wick receivers, sintered metal wicks, and pool boiler receivers. The relative design merits and concerns of the different approaches and technology development test plans are discussed.

    2016-05-01

    External receiver configurations are directly exposed to ambient wind. Therefore, a precise determination of the convective losses is a key factor in the prediction and evaluation of the efficiency of the solar absorbers. Based on several studies, the forced convective losses of external receivers are modeled using correlations for a roughened cylinder in a cross-flow of air. However at high wind velocities, the thermal efficiency measured during the Solar Two experiment was considerably lower than the efficiency predicted by these correlations. A detailed review of the available literature on the convective losses of external receivers has been made. Three CFD models of different level of detail have been developed to analyze the influence of the actual shape of the receiver and tower configuration, of the receiver shape and of the absorber panels on the forced convective heat transfer coefficients. The heat transfer coefficients deduced from the correlations have been compared to the results of the CFD simulations. In a final step the influence of both modeling approaches on the thermal efficiency of an external tubular receiver has been studied in a thermal FE model of the Solar Two receiver.

As healthcare organizations move toward managed care through a mix of reimbursement systems--many with conflicting incentives--the director of patient accounting must approach each system separately and ensure that the hospital receives all of the reimbursement to which it is entitled. The director of patient accounting must understand the industry and recognize that healthcare reimbursement will almost certainly continue to become more complex rather than simpler.

    McLaughlin, Robert; Krause, L.

    2014-01-01

    Unwanted emissions or signal noise is a major problem for VLF radio receivers. These can occur from man made sources such as power line hum, which can be prevalent for many harmonics after the fundamental 50 or 60 Hz AC source or from VLF radio transmissions such as LORAN, used for navigation and communications. Natural emissions can also be detrimental to the quality of recordings as some of the more interesting natural emissions such as whistlers or auroral chorus may be drowned out by the more common sferic emissions. VLF receivers must selectively filter out unwanted emissions and amplify the filtered signal to a record-able level without degrading the quality.

    An avalanche photodiode (APD) array for ground-based optical communications receivers is investigated for the reception of optical signals through the turbulent atmosphere. Kolmogorov phase screen simulations are used to generate realistic spatial distributions of the received optical field. It is shown that use of an APD array for pulse-position modulation detection can improve performance by up to 4 dB over single APD detection in the presence of turbulence, but that photon-counting detector arrays yield even greater gains.

    Strategy for male infertility looks like a compromise between diagnosis methods with their efficacy and complexity and treatment with their own risks, cost, efficacy. Infertility duration as well as woman's fertility play a key role for such a strategy. Definitive infertility without any correction (secretory azoospermia) will be proposed for alternate projects. Some situations may benefit from specific therapy (hypogonadotropic hypogonadism, anejaculations or retrograde ejaculation). More frequently male hypofertility is suspected with non specific sperm alterations, then assisted reproductive technologies will be discussed. Intra-cervical way artificial insemination with husband semen may be proposed in case of hypospadias, anejaculation, retrograde ejaculation, small volume ejaculate or self-cryostored semen, however negative post-coital test, positive crossed penetration test and positive post-insemination test need to be confirmed. Intrauterine way enhance fertilizing probability by discarding cervical step. It will be justified in case of negative post-coital test as well as crossed penetration test except that sperm preparation allowed to inseminate 500,000 to 1 million motile spermatozoa. Both rigorous monitoring and synchronism between insemination and ovulation enhance the efficacy of IU AIH which allowed a two to four fold increase in the pregnancy rate on a total of six cycles. In vitro fertilization for male factor represent around 15% of all IVF attempts. Both decrease in the fertilization rate and the increase in the pregnancy rate by transfer as compared with tubal factor are well accepted. The fertilization failure remain difficult to explain and need to be cautiously confirmed. Thus IVF represent an actual fertilization test but remain limited by the heterogeneity of parameters under "male factor".(ABSTRACT TRUNCATED AT 250 WORDS)

    Dual-system families, those involved with the child welfare system and receiving public cash assistance, may be more vulnerable than families only connected to either of the two systems. This study advances our understanding of the heterogeneous and dynamic cash assistance histories of dual-system families in the post-welfare reform era. With merged administrative data from [state name removed] over the period 1998 to 2009, we use cluster analysis to group month-to-month sequences of cash assistance use among households over the 37-month period surrounding child removal. Close to two thirds of families who received any assistance either had a short spell of Temporary Assistance for Needy Families (TANF) or lost TANF. Smaller percentages had steady support. Families who lose assistance are less likely than average to reunify while those who connect to benefits are more likely, suggesting coordination between systems may serve dual-system families well.

    The introduction of the operative microscope for andrological surgery in the 1970s provided enhanced magnification and accuracy,unparalleled to any previous visual loop or magnification techniques.This technology revolutionized techniques for microsurgery in andrology.Today,we may be on the verge of a second such revolution by the incorporation of robotic assisted platforms for microsurgery in andrology.Robotic assisted microsurgery is being utilized to a greater degree in andrology and a number of other microsurgical fields,such as ophthalmology,hand surgery,plastics and reconstructive surgery.The potential advantages of robotic assisted platforms include elimination of tremor,improved stability,surgeon ergonomics,scalability of motion,multi-input visual interphases with up to three simultaneous visual views,enhanced magnification,and the ability to manipulate three surgical instruments and cameras simultaneously.This review paper begins with the historical development of robotic microsurgery.It then provides an in-depth presentation of the technique and outcomes of common robotic microsurgical andrological procedures,such as vasectomy reversal,subinguinal varicocelectomy,targeted spermatic cord denervation (for chronic orchialgia) and robotic assisted microsurgical testicular sperm extraction (microTESE).

    Teleseismic receiver functions contain information regarding Earth structure beneath a seismic station. P-to-SV converted phases are often used to characterize crustal and upper-mantle discontinuities and isotropic velocity structures. More recently, P-to-SH converted energy has been used to interrogate the orientation of anisotropy at depth, as well as the geometry of dipping interfaces. Many studies use a trial-and-error forward modeling approach for the interpretation of receiver functions, generating synthetic receiver functions from a user-defined input model of Earth structure and amending this model until it matches major features in the actual data. While often successful, such an approach makes it impossible to explore model space in a systematic and robust manner, which is especially important given that solutions are likely non-unique. Here, we present a Markov chain Monte Carlo algorithm with Gibbs sampling for the interpretation of anisotropic receiver functions. Synthetic examples are used to test the viability of the algorithm, suggesting that it works well for models with a reasonable number of free parameters (<˜20). Additionally, the synthetic tests illustrate that certain parameters are well constrained by receiver function data, while others are subject to severe trade-offs-an important implication for studies that attempt to interpret Earth structure based on receiver function data. Finally, we apply our algorithm to receiver function data from station WCI in the central United States. We find evidence for a change in anisotropic structure at mid-lithospheric depths, consistent with previous work that used a grid search approach to model receiver function data at this station. Forward modeling of receiver functions using model space search algorithms, such as the one presented here, provide a meaningful framework for interrogating Earth structure from receiver function data.

  4. Wake-Up-Receiver Concepts - Capabilities and Limitations

    Full Text Available A promising idea for optimising the power consumption of mobile communication devices represents the usage of an additional ultra-low-power receiver unit, which is able to control the main transceiver in order to reduce the standby power consumption of the overall system. Such a Wake-Up-Receiver (WuRx unit senses the medium and switches on the communication interfaces in case of an external request. Otherwise, all system components for the network communication are completely switched off. Especially in the domain of resource-limited and embedded devices, WuRx technologies enable novel communication paradigms.But on the application layer, not all scenarios allow the efficient usage of such WuRx technologies. Dependent on environmental parameters, technological limitations and conceptual requirements, different strategies are necessary to ensure energy-efficient system operation. In this article, we present a critical analysis of the capabilities and the conceptual limitations of WuRx approaches. Therefore, we identify critical parameters for WuRx concepts, which limit the efficiency in real world scenarios. Our goal is to classify sufficient fields of application. Furthermore we evaluate the influences of these parameters on the system behaviour. In addition, we introduce heterogeneous energy harvesting approaches as an efficient way for the system optimisation. The proposed technologies are capable to be integrated into small-sized wireless sensor platforms and prolong the system uptime significantly. The presented simulation results are focusing on actual smart metering scenarios and wireless sensor networks. Based on these measurements, we were able to apply further optimisation steps within the system configuration on the application layer. In this context, we focus on application-specific key issues, like the trade-off between measurement quality and quantity, the usage of data buffering approaches and QoS capabilities.
