    The purpose of presenting this work, besides the interest that shows the mucormycosis pathology not so frequent, it is to carry out a clinical correlation photographic with the imagenology, particularly with the bone scintillography. In the Nuclear Medicine Service it is carried out bone scintillography of three phases previous endovenous administration of 30 mCi (1110 MBq) of {sup 99m} Tc-MDP. The images are obtained with a gamma camera model Elscint APEX SPX, first each 2 seconds during the first minute, then early image to the 5 minutes and finally the late ones to the 3 hs. The bone scintillography in the phases 2 and 3 detects bigger radioactive density in left hemi side, with increment of the osteoblast activity mainly in the medial border and the floor of the orbit, in the malar bone and a little more tenuous in the superior maxillary.

  7. Predicate Argument Structure Analysis for Use Case Description Modeling

    Science.gov (United States)

    Takeuchi, Hironori; Nakamura, Taiga; Yamaguchi, Takahira

    In a large software system development project, many documents are prepared and updated frequently. In such a situation, support is needed for looking through these documents easily to identify inconsistencies and to maintain traceability. In this research, we focus on the requirements documents such as use cases and consider how to create models from the use case descriptions in unformatted text. In the model construction, we propose a few semantic constraints based on the features of the use cases and use them for a predicate argument structure analysis to assign semantic labels to actors and actions. With this approach, we show that we can assign semantic labels without enhancing any existing general lexical resources such as case frame dictionaries and design a less language-dependent model construction architecture. By using the constructed model, we consider a system for quality analysis of the use cases and automated test case generation to keep the traceability between document sets. We evaluated the reuse of the existing use cases and generated test case steps automatically with the proposed prototype system from real-world use cases in the development of a system using a packaged application. Based on the evaluation, we show how to construct models with high precision from English and Japanese use case data. Also, we could generate good test cases for about 90% of the real use cases through the manual improvement of the descriptions based on the feedback from the quality analysis system.

    The purpose of this study was to examine case managers' (CM) job position descriptions through content analysis. There were 29 case manager job position descriptions examined. The job descriptions could be grouped into four categories: (1) what the individuals should bring to the position, (2) what they did as CM, (3) to whom they were accountable, and (4) what was valued. Themes included focus on client as individual, focus on the external/system, or outer-directed work, and the articulation point between the individual and broader system. The CM works directly and indirectly in the system and community through education, organizing, planning, and networking, as well as through provision of direct care to the individual client. The expectations of the positions are extensive.

    Full Text Available By combining the advantages of argument map and Bayesian network, a case description model based on evidence (CDMBE, which is suitable to continental law system, is proposed to describe the criminal cases. The logic of the model adopts the credibility logical reason and gets evidence-based reasoning quantitatively based on evidences. In order to consist with practical inference rules, five types of relationship and a set of rules are defined to calculate the credibility of assumptions based on the credibility and supportability of the related evidences. Experiments show that the model can get users’ ideas into a figure and the results calculated from CDMBE are in line with those from Bayesian model.

    Full Text Available Gitelman syndrome is a rare inherited tubulopathy, characterized by hypomagnesemia, hypokalemia, metabolic alkalosis, hypocalciuria and hyperreninemic hyperaldosteronism. The clinical spectrum is wide and includes: cramps, myalgies, muscle weakness, until episodes of carpo-podalic spasm, tetania, rabdomyolisis and paralysis. Some cases have been described in literature underlining the association of this condition with chondrocalcinosis, as a typical example of hypomagnesemia-induced crystal deposition disease. The therapy of Gitelman syndrome consists on the administration of defective electrolytes, althought not always effective. We describe two cases of Gitelman syndrome associated with chondrocalcinosis showing the wide range of presentation of this clinical condition.

    Full Text Available Erythema nodosum (EN is a dermatosis of unclear etiology, which is characterized by vascular lesion of the skin; it shows itself as hard painful nodes occurring in the derma or subcutaneous fat on the shins and thighs. EN has been described in many chronic infectious processes with some features of its clinical course. In most cases, the disease is regarded as a nonspecific immunoinflammatory response to a wide spectrum of etiological factors, including that in gestation, which presents certain problems in curing the patient. The example given below supports the need for timely testing for infectious markers in pregnancy and, in case of evolving EN, for using not only nonsteroidal anti-inflammatory drugs, but also pathogenetic treatment.

  19. Mode shape description of an aero-engine casing structure using Zernike moment descriptors

    Institute of Scientific and Technical Information of China (English)

    LIU Ying-chao; ZANG Chao-ping

    2011-01-01

    Vibration mode shape description of an aero-engine casing structure using Zernike moment descriptor (ZMD) was introduced in this paper. The mode shapes of the aero-engine casing structure can be decomposed as a linear combination of a series of Zernike polynomials, with the feature of each Zernike polynomial reflecting a part of characteristic of mode shapes, based on Zernike moment transformation. Meanwhile, the reconstruction of mode shapes with ZMD was explored and its ability to filtering the noise contaminated in the mode shapes was studied. Simulation of the aero-engine casing structure indicated the advantage of this method to depict the mode shapes of a symmetric structure. Results demonstrate that the Zernike moment description of the mode shapes can effectively describe the double modes in the symmetric structure and also has the ability to remove or significantly reduce the influence of noise in the mode shapes. Such feature shows great practical value for further research on the correlation, model updating and model validation of the symmetric structure's finite element model.

    Gupta, Hari S; Komondoor, Raghavan; Rama, Girish M

    2010-01-01

    A number of companies are trying to migrate large monolithic software systems to Service Oriented Architectures. A common approach to do this is to first identify and describe desired services (i.e., create a model), and then to locate portions of code within the existing system that implement the described services. In this paper we describe a detailed case study we undertook to match a model to an open-source business application. We describe the systematic methodology we used, the results of the exercise, as well as several observations that throw light on the nature of this problem. We also suggest and validate heuristics that are likely to be useful in partially automating the process of matching service descriptions to implementations.

  2. Bridging molecular and continuous descriptions: the case of dynamics in clays

    Directory of Open Access Journals (Sweden)

    Jean-François Dufrêche

    2010-03-01

    Full Text Available The theory of transport in porous media such as clays depends on the level of description. On the macroscopic scale,hydrodynamics equations are used. These continuous descriptions are convenient to model the fluid motion in a confined system. Nevertheless, they are valid only if the pores of the material are much larger than the molecular size of the components of the system. Another approach consists in using molecular descriptions. These two methods which correspond to different levels of description are complementary. The link between them can be clarified by using a coarse-graining procedure where the microscopic laws are averaged over fast variables to get the long time macroscopic laws. We present such an approach in the case of clays. Firstly, we detail the various levels of description and the relations among them, by emphasizing the validity domain of the hydrodynamic equations. Secondly, we focus on the case of dehydrated clays where hydrodynamics is not relevant. We show that it is possible to derive a simple model for the motion of the cesium ion based on the difference on time scale between the solvent and the solute particles.A teoria de transporte em meios porosos tais como argilasdepende do nível de descrição. Na escala macroscópica, equações da hidrodinâmica são utilizadas. Tais descrições a níveldo contínuo são convenientes para tratar o movimento do fluido em sistemas confinados. No entanto, tais equações são válidas se os poros do material são muito maiores do que as moléculas das componentes do sistema. Uma outra abordagem consiste em usar descrições moleculares. Esses dois métodos que correspondem a diferentes níveis de descriçãosão complementares. A ligação entre eles pode ser elucidada usando um procedimento de mudança de escala onde são tomadas médias das leis microscópicas sobre as variáveis rápidas para se obter as leis macroscópicas para tempos longos.

  5. Case report. First description of adiaspiromycosis in an Eurasian otter (Lutra lutra in Italy

    Directory of Open Access Journals (Sweden)

    Daniela Malatesta

    2014-09-01

    Full Text Available Adiaspiromycosis is a pulmonary disease caused by the inhalation of the ubiquitous fungus Emmonsia spp., a common soil inhabitant. Information about the replication and dissemination of the fungus from the primary site is lacking. Members of the Family Mustelidae seem to be highly susceptible to this infection, which has been previously reported in otters (Lutra lutra in Czech Republic/Slovakia, Finland and in the UK. In many cases, Emmonsia-associated lesions have also been reported as incidental findings during necropsies of otherwise healthy animals. A road-killed male Eurasian otter was submitted for the post-mortem examination on 21st December 2009 at the Veterinary Pathology Unit of the Faculty of Veterinary Medicine of Teramo, as part of the RECAL [RECovery and post‑mortem Analysis of Eurasian otters (Lutra lutra in the National Park of Cilento, Vallo di Diano and Alburni (Salerno, Italy, and surrounding areas] project. Histologically, multifocal round structures with a PAS-positive thick tri-laminar wall and a central basophilic granular mass were observed within the alveoli. The adiaspores were surrounded by a severe granulomatous reaction with high number of macrophages, multinucleated giant cells, eosinophils, neutrophils and fibroblasts. Numerous multifocal cholesterol granulomas were observed close to those fungal-induced. To the best of our knowledge, this is the first description of adiaspiromycosis in an Eurasian otter in Italy.

  6. Clinicopathological description of two cases with SQSTM1 gene mutation associated with frontotemporal dementia.

    There is a strong genetic influence on the clinicopathological phenotypes associated with frontotemporal lobar degeneration (FTLD) and frontotemporal dementia (FTD). Intracellular deposition of TDP-43 is the phenotypical hallmark of a frequent subgroup of cases. Mutations in the sequestosome 1 (SQSTM1) gene have rarely been found in individuals with FTD. Here we provide a comprehensive clinicopathological description of two cases with a SQSTM1 mutation. The clinical phenotype of patient 1 (mutation p.Glu396*) was compatible with the behavioural variant (bv) of FTD. TDP-43 pathology was consistent with the features of type B of FTLD-TDP pathology. However, prominent neuronal granular cytoplasmic TDP-43 immunoreactivity and abundant oligodendroglial inclusions, proven by colocalization with the oligodendroglial-marker TPPP/p25, were also seen. The clinical phenotype of patient 2 was compatible with bvFTD associated with parkinsonism and bulbar symptoms in the later stage. Genetic testing of patient 2 identified a C9orf72 repeat expansion mutation together with a missense mutation (p.Arg212Cys) in SQSTM1. TDP-43 pathology was characterized by neuritic profiles compatible mostly with type A. In contrast to patient 1, p62 pathology was seen to a greater extent as TDP-43 immunoreactivity in neurons. Using an antibody that detects poly(GP) peptides produced via repeat associated non-ATG translation associated with expanded hexanucleotide repeat in the C9orf72 gene, we confirmed the presence of pathognomonic inclusions. The present study supports previous observations on amyotrophic lateral sclerosis (ALS) that SQSTM1 mutations consistently associate with TDP-43 pathology. The co-presence of C9orf72 mutation may influence the phenotype, thus finding one FTLD (or ALS) related mutation does not exclude the presence of further influential genetic alterations. Oligodendroglial TDP-43 pathology is considerable in some forms of FTLD-TDP, thus their evaluation might be considered

    2008-12-01

    Full Text Available Abstract Background Previous efforts to produce case descriptions have typically not focused on the organizations that produce research evidence and support its use. External evaluations of such organizations have typically not been analyzed as a group to identify the lessons that have emerged across multiple evaluations. Case descriptions offer the potential for capturing the views and experiences of many individuals who are familiar with an organization, including staff, advocates, and critics. Methods We purposively sampled a subgroup of organizations from among those that participated in the second (interview phase of the study and (once from among other organizations with which we were familiar. We developed and pilot-tested a case description data collection protocol, and conducted site visits that included both interviews and documentary analyses. Themes were identified from among responses to semi-structured questions using a constant comparative method of analysis. We produced both a brief (one to two pages written description and a video documentary for each case. Results We conducted 51 interviews as part of the eight site visits. Two organizational strengths were repeatedly cited by individuals participating in the site visits: use of an evidence-based approach (which was identified as being very time-consuming and existence of a strong relationship between researchers and policymakers (which can be challenged by conflicts of interest. Two organizational weaknesses – a lack of resources and the presence of conflicts of interest – were repeatedly cited by individuals participating in the site visits. Participants offered two main suggestions for the World Health Organization (and other international organizations and networks: 1 mobilize one or more of government support, financial resources, and the participation of both policymakers and researchers; and 2 create knowledge-related global public goods.

    The Solomon Islands has one of the highest rates of domestic violence in the world. This paper is a descriptive case series of all cases of domestic violence presenting to the Solomon Islands National Referral Hospital (NRH) over 18 years. Data were routinely collected from a database of all patients who were treated by NRH general surgery and orthopedic clinicians between 1994 and 2011, inclusive. The total number of cases in the injury database as a result of domestic violence was 387. The average number of cases in the database per year from 1994 to 2011 was 20. There were 6% more female patients (205 of 387; 53%) than male (182 of 387; 47%). Of the cases in which the perpetrator of the violence against a female patient was specified (111 of 205 female cases), 74% (82 of 111) were the patient's husband. Only 5% (5 of 111) of cases in females were inflicted by another female. This analysis provides the best available information on domestic violence cases requiring a visit to a tertiary hospital in a Pacific Island in the specified time period and is undoubtedly an under-estimate of the total cases of domestic violence. Preventing and treating domestic violence in the Solomon Islands and in the Pacific is an important challenge and there is a significant role for secondary and tertiary health services in screening for and preventing domestic violence.

  14. Review Article: "The Lagrangian description of aperiodic flows: a case study of the Kuroshio Current"

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available This article reviews several recently developed Lagrangian tools and shows how their combined use succeeds in obtaining a detailed description of purely advective transport events in general aperiodic flows. In particular, because of the climate impact of ocean transport processes, we illustrate a 2-D application on altimeter data sets over the area of the Kuroshio Current, although the proposed techniques are general and applicable to arbitrary time dependent aperiodic flows. The first challenge for describing transport in aperiodical time dependent flows is obtaining a representation of the phase portrait where the most relevant dynamical features may be identified. areas that are related to confinement regions. This representation is accomplished by using global Lagrangian descriptors that when applied for instance to the altimeter data sets retrieve over the ocean surface a phase portrait where the geometry of interconnected dynamical systems is visible. The phase portrait picture is essential because it evinces which transport routes are acting on the whole flow. Once these routes are roughly recognised, it is possible to complete a detailed description by the direct computation of the finite time stable and unstable manifolds of special hyperbolic trajectories that act as organising centres of the flow.

    Russell body esophago-gastro-duodenitis is an unusual form of chronic inflammation, with only 22 cases being reported in PubMed. However, the prevalence and clinical significance remain unknown. This report describes the clinico-pathological characteristics of nine cases of Russell body gastritis (RBG) and one case of Russell body duodentitis (RBD), with nonspecific endoscopic appearance. The Mott cells (plasma cells with Russell bodies) showed κ light chain restriction in eight gastritis cases and λ light chain restriction in the duodentitis case, and there were no histological features that suggested lymphoma. Thus, a diagnosis of monoclonal RBG/RBD was made. Helicobacter pylori infection was found in 55.6% of RBG cases and in the RBD case. And, the clinical follow-up evaluations were uneventful. This report is the first study to describe this benign disease entity with monoclonality on a large-scale basis. In addition, the monoclonality of Mott cells cannot be used as evidence of an existing neoplastic lesion, and taken together, these findings may indicate a reactive process. PMID:25001185

    Full Text Available Gestational trophoblastic disease (GTD is a term used for a group of pregnancy-related tumors. Gestational trophoblastic neoplasia (GTN, is recognized as the most curable gynecologic malignancy. However, many cases are resistant to first line chemotherapy. We present cases of invasive mole. They were diagnosed as a vesicular mole on ultrasonography and underwent suction and evacuation but vaginal bleeding recurred with plateau and rising B-hcg with intramyometrial vascular lesion. Hysterectomy was done that indicated invasive mole. Patients were cured of their symptoms. Surgical therapy (hysterectomy with chemotherapy has shown to achieve remission in these cases especially with resistance to chemotherapy and in perimenopause.

    Hemangiosarcoma (HSA) is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be comm...

    Cornet, R; Abu-Hanna, A

    2002-01-01

    Research in (medical) terminological knowledge representation is showing an increased interest in the family of Description Logics (DLs), as they allow for automatic reasoning. This interest is driven by an increase in demands on the quality of and reasoning ability with medical terminological knowledge. Recent advances in Computer Science have demonstrated the computational decidability and empirical tractability of quite expressive DLs. The question arises whether this expressivity is usable and useful. This paper motivates and describes an exploratory study to address this question by examining the surplus value of individual DL constructors based on an investigation of UMLS terms. Our study indicates that the disjunction and negation operators comprise very valuable extensions to current DLs. The impact of formalization depends on the involved semantic type; "Injury and Poisoning" is one of the semantic types in which a large portion of concepts will benefit from the extension.

    The KDD community has described a multitude of methods for knowledge discovery on large datasets. We consider some of these methods and integrate them into an analyst s workflow that proceeds from the data-centric descriptive level to the model-centric causal level. Examples of the workflow are shown for the Health Indicators Warehouse, which is a public database for community health information that is a potent resource for conducting data science on a medium scale. We demonstrate the potential of HIW as a source of serious visual analytics efforts by showing correlation matrix visualizations, multivariate outlier analysis, multiple linear regression of Medicare costs, and scatterplot matrices for a broad set of health indicators. We conclude by sketching the first steps toward a causal dependence hypothesis.

  2. Frequency of Certain Established Risk Factors in Soft Tissue Sarcomas in Adults: A Prospective Descriptive Study of 658 Cases

    2008-01-01

    Full Text Available Soft tissue sarcomas are rare tumours with infrequent identified aetiological factors. Several genetic syndromes as well as previous radiation therapy and/or chronic lymphoedema have been suspected to predispose to some soft tissue sarcomas. Between January 1997 and September 2005, we carried out a prospective descriptive study to estimate the frequency of some particular etiological factors among 658 patients with soft tissue sarcomas. Sarcomas associated with a clinically identified genetic disease represent 2.8% out of all cases (95%CI: 1.5–3.8%. Most of these cases (14/19 are related to Recklinghausen neurofibromatosis. Radiation-induced sarcomas represent 3.3% out of all cases (95%CI: 1.7–5.1%. Most of these cases (9/22 are related to prior breast cancer treatment. We had observed only 1 case of Stewart-Treves syndrome. Liposarcoma, the most frequent histological subtype observed, is not associated with any particular aetiological entity. Finally, most of the adult soft tissue sarcomas are not related to any classical clinically identified genetic disease or previous radiation therapy and/or chronic lymphoedema risk factors. Frequency of underlying genetic syndrome which may predispose to soft tissue sarcomas could be higher than previously reported.

    The efficacy of oral bactericidal antibiotics in the treatment of osteomyelitis is analyzed retrospectively by a review of 9 cases histories. The first patient was treated in 1982. Clinical and laboratory controls were reviewed up to 1.1.1995. In 6 patients S. aureus was isolated, while in 3 patients the organism could not be cultured but gram + cocci were almost likely. 5 cases of osteomyelitis were acute, 4 were chronic and in one case there was an infection of an artificial knee prothesis. The isolated S. aureus were sensitive to the antibiotics prescribed. 8 patients received a combination of flucloxacillin (2-4 g/day) and rifampicin (600 mg/day); one patient was treated with the combination amoxicillin/clavulanic acid (1500/425 mg/day) followed by ofloxacin (400 mg/day) and finally co-trimoxazole (320/1600 mg/day). 3 patients received all antibiotics orally; in 6 patients oral administration followed a short intravenous course of the antibiotic combination. The duration of treatment varied between 6 and 23 weeks. Follow-up extended over 9 months (n = 1), 14 months (n = 3), 4-7 years (n = 3), and 10-12 years (n = 2). In 8 cases the osteomyelitis was cured (89%). In our view, a combination of bactericidal oral antibiotics with good penetration into bone tissue can be prescribed in selected cases of osteomyelitis to shorten or even avoid the standard intravenous therapy of acute or chronic diseases.

    We have reviewed all documented cases of mandibular canine transmigration from 1951 (when to our knowledge the first case was published) to 2015, and retrospectively evaluated nine further sequential cases of transmigrating mandibular canines in one hospital by analysing relevant data, including patients' age and sex, presence of retained deciduous canines, radiographic changes, coexisting systemic diseases, and treatment. Transmigration of a mandibular canine is a rare anomaly of eruption, and extraction is the usual treatment. The nine new patients were aged from 16 -48 years, eight of the transmigrated canines were unilateral, and one patient had them bilaterally. They were all completely impacted. Four were retained primary teeth, and five exfoliated primary canines. Eight had no associated radiographic or clinical abnormalities, while one patient had an associated odontoma. Six mandibular canines were removed and three kept under observation. Early detection of transmigrated canines gives the opportunity to monitor their development, which may improve prognosis and treatment.

    Full Text Available Xanthogranulomatous pyelonephritis is a rare and peculiar form of chronic pyelonephritis and is generally associated with renal lithiasis. Its incidence is higher in females. The peculiarity of this disease is that it requires a differential diagnosis, because it can often simulate dramatic pathologic conditions. In fact, in the literature are also described cases in association with squamous cell carcinoma of the kidney The radiologic clinical findings simulate renal masses, sometimes in association with caval thrombus. We describe a case of xanthogranulomatous pyelonephritis with radiologic aspects of a complex cyst of Bosniak class III in a man 40-year old.

    Directory of Open Access Journals (Sweden)

    B.F. Von Teichman

    1998-07-01

    Full Text Available Five cases of Mokola virus, a lyssavirus related to rabies, are described. The cases occurred in cats from the East London, Pinetown and Pietermaritzburg areas of South Africa from February 1996 to February 1998. Each of the cats was suspected of being rabid and their brains were submitted for laboratory confirmation. Four of the cases were positive, but with atypical fluorescence, and 1 was negative. Mokola virus infection was identified by anti-lyssavirus nucleocapsid monoclonal antibody typing. As in rabies cases, the predominant clinical signs were of unusual behaviour. Aggression was present, but only during handling. Four of the 5 cats had been vaccinated for rabies, which is consistent with other studies that show that rabies vaccination does not appear to protect against Mokola virus. Since Mokola may be confused with rabies, the incidence of Mokola virus may be more common in Africa than is currently reported. As human infections may be fatal, the emergence of this virus is a potential threat to public health.

    Educational achievement, which for individuals with the metabolic disorder classic galactosemia (GAL) is significantly lower than in the wider population, correlates with self-reported quality of life. Phonological awareness skills underpin the development of literacy, and although literacy is a key contributor to successful academic outcomes, no study to date has investigated phonological awareness skills in children with GAL. This study investigated phonological awareness (PA) in four school-aged children with the disorder, two of whom were siblings. Age range for the children was 7 years 7 months to 9 years 2 months. Each child was assessed with the Phonological Awareness criterion-referenced subtest from the Clinical Evaluation of Language Fundamentals-Fourth Edition. Included in the data for analysis was each child's performance measures obtained from their most recent assessment of cognitive and lexical development. A number of descriptive analyses were undertaken on the data. One child, who met her age criterion for PA, had cognitive and lexical development skills in the average range. The remaining three children failed to meet their age criteria. Although these three children presented with clinically similar cognitive and lexical development skills, disparate PA skills were identified. The PA skills of one of the sibling pair were notably more advanced than his older sibling. The limitations of relying on behavioural test results in children with GAL to predict those most at risk of reduced skill development are discussed in terms future research directions.

    Objective:To identify the clinical manifestations of hump nosed viper envenomation and to recognize the available treatment methods to prevent complications.Methods: Descriptive observational study involving a series of1 543 patients admitted with hump nosed viper bite to 5 major hospitals in Sri Lanka was conducted. Data collection was done consecutively during February1990 and February2008. ExceptHypnale, identification of the biting snake was made by the corresponding author after visual examination of the dead or live snakes, which were brought to hospital.Results: Sixty seven(4.34%) patients developed systemic effects and two (0.1%) patients died due to effects of envenomation or complications of treatment. Systemic effects varied from coagulopathy, nephropathy to some neurological manifestations. Fifty nine (3.8%) patients had only coagulopathy and they received either, intravenous isotonic saline to ensure adequate urine out put i.e.0.5 mL/kg /hour or15 mL/kg of fresh frozen plasma(FFP). None of the patients that had coagulopathy developed renal failure. Contamination of the sample by mildly venomous species ofHypnale may have contributed to the low incidence of systemic complications.Conclusions: It is likely that early hydration with normal saline orFFP can prevent acute renal failure. FFP showed a tendency for early correction of coagulopathy. Role of FFP in hump nosed viper envenomation is worth studying in randomized double blind controlled clinical trials.

    A few cases of death worldwide during GH treatment in pediatric patients with Prader-Willi syndrome (PWS) have been recently described. The evaluation of further cases is needed to better identify possible causal mechanism(s), as well as to suggest some additional guidelines for prevention. We report the death of 2 additional children with genetically confirmed PWS in the first months of GH therapy. Case 1: This 3.9-yr-old girl was born at 39 weeks gestation. Low GH response to two stimulation tests was observed. GH administration was started at the age of 3.5 yr (0.33 mg/kg per week), when the patient was at 130% of her ideal body weight (ibw). Hypertrophy of adenoids was previously demonstrated. Snoring and sleep apnea were present before GH treatment, and did not increase during therapy. Four months later she died at home suddenly in the morning. Case 2: This patient was a 6.3-yr-old boy. He was born at term after an uneventful pregnancy. At the age of 6 yr, his weight was at 144% of his ibw. He showed reduced GH secretion during provocation tests, and GH therapy was started (0.20 mg/kg per week). The previously reported nocturnal respiratory impairment had worsened after beginning GH administration. Tonsils and adenoids hypertrophy were noted. At the age of 6.3 yr he died at home in the morning following an acute crisis of apnea. These additional cases seem to confirm that some children with PWS may be at risk of sudden death at the beginning of GH therapy. PMID:16117198

  13. Intervertebral disc calcification in children: Case description and review of relevant literature

    International Nuclear Information System (INIS)

    Intervertebral disc calcification is a rare condition in children; in most cases, it is asymptomatic and therefore not diagnosed. In our study, we present a case of idiopathic intervertebral disc calcification within the cervical segment, at the level of C2/C3 and C4/C5 vertebrae in a 5-year-old girl with torticollis. Basic neurological examination supplemented by X-ray examination was performed, showing calcification within the cervical segment at the level of C2/C3 and C4/C5 vertebrae. In order to complement the diagnostics, a CT scan of the cervical spine was performed; the scan confirmed the diagnosis and revealed additional calcification of the anterior longitudinal ligament at the level of C4/C5 vertebrae

    Full Text Available In prepuberal girls vulvo-vaginitis are caused by germs of intestinal origin,mycetes, Gardnerella vaginalis, protozoa. Shigella is an uncommon agent able to induce valvovaginitis in children. We report the case of a 7-year-old girl with chronic vulvo-vaginitis caused by S. flexneri. Antibiotic Susceptibility Testing revealed that S. flexnery was sensible to cefotaxime, amoxicillin, imipenem, ciprofloxacin, but resistant to amikacin, cefazolin, gentamycin, ampicillin and tetracycline. A treatment with ciprofloxacin brought to a rapid resolution of all symptoms. At the follows up at 3 and 6 months the patient did not report symptoms of infection or articular cartilage abnormality; microbiological evaluations were also negative. Even if it is a single case report and other clinical trial may be performed in order to validate this hypothesis,we speculate that in patient with vulvo-vaginal infection living in environment with low hygiene care, a carefully microbiological evaluation of uncommon agents may be performed.

  17. The usefulness of CBF brain SPECT in forensic medicine. A description of four cases

    International Nuclear Information System (INIS)

    The aim of this study was to show the applications of cerebral blood flow SPECT scanning in forensic medicine using four cases: two suspects and two victims of crime. Cerebral blood flow studies were performed with the use of 99mTc-ECD and a triple head gammacamera. Qualitative and quantitative analysis was performed, utilising an asymmetry index for unilateral perfusion deficits and a comparison to cerebellar perfusion for assessing the regional cerebral perfusion. For assessing the normal values, a control group of 30 patients was studied. In these cases CBF SPECT scanning proved its usefulness in medico-legal argument and played an important role in formulating the final forensic expertTMs opinion. Radionuclide cerebral blood flow studies may play a role in forensic medicine, where this method it is mostly under-utilised at present. (author)

    Full Text Available ABSTRACT OBJECTIVE: Describe the clinical and laboratory profile, follow-up, and outcome of a series of cases of acute viral myositis. METHOD: A retrospective analysis of suspected cases under observation in the emergency department was performed, including outpatient follow-up with the recording of respiratory infection and musculoskeletal symptoms, measurement of muscle enzymes, creatine phosphokinase (CPK, lactate dehydrogenase (LDH, transaminases (AST and ALT, blood count, C-reactive protein, and erythrocyte sedimentation rate in the acute phase and during follow-up until normalization. RESULTS: Between 2000 and 2009, 42 suspected cases were identified and 35 (27 boys were included. The median age was 7 years and the diagnosis was reported in 89% in the first emergency visit. The observed respiratory symptoms were cough (31%, rhinorrhea (23%, and fever (63%, with a mean duration of 4.3 days. Musculoskeletal symptoms were localized pain in the calves (80%, limited ambulation (57%, gait abnormality (40%, and muscle weakness in the lower limbs (71%, with a mean duration of 3.6 days. There was significant increase in CPK enzymes (5507 ± 9180 U/L, LDH (827 ± 598 U/L, and AST (199 ± 245 U/L, with a tendency to leukopenia (4590 ± 1420 leukocytes/mm3. The complete recovery of laboratory parameters was observed in 30 days (median, and laboratory and clinical recurrence was documented in one case after 10 months. CONCLUSION: Typical symptoms with increased muscle enzymes after diagnosis of influenza and self-limited course of the disease were the clues to the diagnosis. The increase in muscle enzymes indicate transient myotropic activity related to seasonal influenza, which should be considered, regardless of the viral identification, possibly associated with influenza virus or other respiratory viruses.

    Full Text Available A clinical case of Relapsing Polychondritis (RP with Microscopic Polyangiitis (MPA is described in a 66 years old woman. This case rappresents a rare association of the two pathologies. Polychondritis is a rare infiammatory disease of unknown origin, but immunological mechanisms are essential in the pathogenesis. Histological features are infiammation and destruction of cartilage. The disease is systemic, may have a remitting course. The osteoarticular lesions are sometimes unusual, involving the temporomandibular or cervical articolations, and the renal lesions may be severe. This can be primary or associated with several other diseases. Microscopic Polyangiitis is a systemic disorder characterized by necrotizing vasculitis, affecting the small vessels. Most patient with MPA have Antineutrophil Cytoplasmic Antibodies for Myeloperoxidase (MPO-ANCA. ANCA have become an astablished tool for the diagnosis of systemic vasculitis. The primary target antigens for ANCA are myeloperoxidase (enzyme present in the secretory granules of neutrophils and monocytes and antibodies to these antigens are tested by ELISA and IIF (indirect immunofluorescence. We describe a case of histologically confirmed MPA with Relapsing Polychondritis. Clinically she presented livedo reticulris in the lower limbs and pain in the joints. During the follow-up the patient developed asymetric oligoarticular arthritis. Immunosuppressive drugs like glucocorticoids and cyclofosfamide are the drugs of choice, depending on the stage and severity of the disease.

    Full Text Available Hemangiosarcoma (HSA is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be communicated to those responsible for the pets, so that, with all available information, they can make a free and informed choice about the treatment they want for their pet, considering the financial commitment, survival time and quality of life associated with chemotherapy. This article describes the clinical case of a female greyhound dog of eight years of age that was brought to consultation for a skin tumor on the right hind limb in the distal tibia. She was diagnosed with noninvasive cutaneous HSA through histopathology, reason why the owners chose not to do the chemotherapy; however, 10 months later she presented recurrent skin lesions and a popliteal lymph node corresponding to hemangiosarcoma and hemangioma respectively, and three weeks later the patient developed cardiac tamponade due to a cardiac mass with associated spill, which resulted in her euthanasia.

  8. Mass transfer through clay by diffusion and advection: description of INTRAVAL Test Case 1a

    International Nuclear Information System (INIS)

    UK Nirex Ltd is planning the development of a deep geological repository for the disposal of solid low-level and intermediate-level radioactive waste. The rock surrounding such a waste repository is an important barrier restricting the return of radionuclides in the waste to Man's environment. It is important to validate the models used in Safety assessments of such a repository. The international INTRAVAL project is specifically concerned with the validation of models used to describe the transport of radionuclides through the geosphere. INTRAVAL was initiated by the Swedilsh Nuclear Power Inspectorate (SKI) in 1987. The format of the INTRAVAL project is that there are a number of test cases based on well characterized experiments. There is a mixture of laboratory and field experiments and natural analogues. In the first phase of the project there are 14 test cases. This report describes Test Case 1a, which is concerned with laboratory experiments on clay. The experimental techniques and the results of the experiments on which the INTRAVAL analysis is carried out are described. (author)

    Full Text Available Hyperbaric oxygen therapy (HBOT is a safe treatment, provided fulfilling certain rules of patient qualifications to treatment, as well as supervision over the course of therapy by qualified medical staff. Side effects reported in the literature are rare, and are usually mild and transient. Professional medical staff allows minimising the adverse events occurrence. The scale of complications is unknown, especially in Polish hyperbaric center. Careful analysis could be used to develop prevention procedures for patients of hyperbaric oxygen therapy. Hyperbaric Oxygen Centre and Wound Treatment in Bydgoszcz during 28 months performed hyperbaric oxygen therapy (HBOT in case of 423 patients. During this period, adverse events occurred occasionally. 17 cases have been reported. Authors described study case 77 year-old patient who was admitted due to non-healing wound-left lower abdomen (state after radiotherapy. During the fourth session, on decompression phase patient have had a generalized seizure (tonic-clonic. The decompression was stopped, the oxygen supply was disconnected but only after the drug administration seizures terminated. The most likely causative agent of the adverse reactions of the patient treated with HBOT was the oxygen toxic effect on the brain tissue. However, analyzing the circumstances of the seizure termination: phase of decompression at the pressure 2ATA and lack of oxygen disconnection response, it cannot be excluded other causes of this complication.

    2016-01-01

    Systemic sclerosis (Ssc) is an autoimmune connective tissue disease of unknown origin, characterized by progressive fibrosis of the skin and internal organs. Immune reactions taking part in Ssc pathogenesis may contribute to cancer development; therefore patients with risk factors for this disease require observation for a neoplastic process. On the other hand, symptoms of Ssc may be a mask of various cancers. Differentiating between the idiopathic form of Ssc and scleroderma-like paraneoplastic syndrome often causes a lot of difficulties. The article presents two cases of Ssc at the beginning of the disease after 60 years of age. The first case was diagnosed as Ssc, whereas in the second case the defined diagnosis was scleroderma-like syndrome in the course of colorectal cancer. This paper presents an analysis of differential diagnostic procedures which were performed and led to the final diagnosis, mentions types of cancers co-occurring with Ssc and suggests a screening scheme for cancer development in patients with a diagnosis of Ssc.

    Bed bugs are hematophagous insects which due to their morphological and biological characteristics are able to easily adapt themselves to human households. The authors describe two cases of dermatitis caused by bed bug bites in the city of Rio de Janeiro, Brazil. Patients presented linear lesions in the usual "breakfast, lunch and dinner" arrangement, suggesting this diagnosis. A visit to their dwellings showed infestation of insects identified as Cimex hemipterus. The knowledge of these insects by the dermatological community will contribute to an accurate diagnosis as well as subsidize the dissemination of information aiming for prevention. PMID:25830996

  16. The diffusion of the distance Entomology Master's Degree Program at the University of Nebraska Lincoln: A descriptive case study

    Science.gov (United States)

    Hubbell, Jody M.

    This study explored three selected phases of Rogers' (1995) Diffusion of Innovations Theory to examine the diffusion process of the distance Entomology Master's Degree program at the University of Nebraska, Lincoln. A qualitative descriptive case study approach incorporated semi-structured interviews with individuals involved in one or more of the three stages: Development, Implementation, and Institutionalization. Documents and archival evidence were used to triangulate findings. This research analyzed descriptions of the program as it moved from the Development, to the Implementation, and finally, the Institutionalization stages of diffusion. Each respective stage was examined through open and axial coding. Process coding identified themes common to two or more diffusion stages, and explored the evolution of themes from one diffusion stage to the next. At a time of significant budget constraints, many departments were faced with the possibility of merger or dissolution. The Entomology Master's Degree Program evolved from being an entrepreneurial means to prevent departmental dissolution to eventually being viewed as a model for the development of similar programs across this university and other institutions of higher education. During this evolution, the program was reinvented to meet the broader needs of industry and a global student market. One finding not consistent with Rogers' model was that smaller, rather than larger, departmental size contributed to the success of the program. Within this small department, faculty members were able to share their experiences and knowledge with each other on a regular basis, which promoted greater acceptance of the distance program. How quality and rigor may be defined and measured was a key issue in each respective stage. In this specific case, quality and rigor was initially a comparison of on-campus and distance course content and then moved to program-based assessment and measures of student outcomes such as job

    Full Text Available Brachydactyly is an inheritable autosomal genetic malformation, either dominant or recessive. This article describes a gypsy family presenting with congenital brachydactyly. The study was conducted at the Sanitary District of Guadix, in Granada, Spain. The study subjects were four siblings (two women and two men, members of the same family and belonging to the Roma community. Demographic and genetic data were collected. With some variability, they had the phenotypic manifestation of brachydactyly. Radiographic data revealed that it was type A4 brachydactyly, but one of them featured a blend of A4 with E, or perhaps it is a new unclassified variety. All cases showed similar abnormalities in the feet. Besides, they are obese, and have dyslipidemia and different degrees of consanguinity.

    Directory of Open Access Journals (Sweden)

    Annalisa Di Cesare

    2012-01-01

    Full Text Available We report on a rare case of Morquio syndrome, an autosomal recessive mucopolysaccharidosis including type IVA, a deficiency of N-acetylgalctosamine-6-sulfatase and type IVB a deficiency of β-galactosidase. A 43-year-old female patient affected by IVB Morquio syndrome underwent instrumental investigation. Conventional plain films of the entire spine, pelvis, chest and knees together with magnetic resonance imaging of the entire column, hip, knees, and ankles demonstrated the characteristics of skeletal changes of this disease. The main abnormalities were platyspondily and hypoplasia of the odontoid process, genua valga deformity and severe multiple degenerative changes of the hips, knees, and ankle joints. Radiographs and above all magnetic resonance imaging are crucial to provide substantial information about the gravity, evolution of the skeletal and joints changes, and the rehabilitation strategies to be followed.

    1990-01-01

    A case is described of embryonal rhabdomyosarcoma (E.R.) of the middle ear in a 4-year-old child; survival has been over 9 years. R.E. is the most common malignant tumor of the auricular region in children and is most often fatal due to locoregional extensions or secondary metastases carried through the bloodstream and lymphatic systems. The basis for treatment is a multidisciplinary approach to the disease: surgery with as broad an exeresis as possible; radiotherapy with tumor-killing doses of 5,500/6,000 rads; and polychemotherapy (Vincristina, Endoxan, Methotrexate). Such "aggressive" treatment often results in a high rate of morbidity with complications involving the blood, bones, eyes and meninx often requiring temporary suspension of treatment and prolonged hospitalization.

    Full Text Available The occurrence of external root reabsorption can be associated to a persistent and chronic inflammatory process at the periapical area that determines the presence of bone rarefaction lesion promoted by some endogenous or exogenous irritant agent as predisponent factor. In these cases the only form to try to stop evolution is the agent remotion through endodontic treatment or reintervention. A female patient, 40 years old, presented sensibility at the element 11. The radiographic image showed discreet external root reabsorption in apical third of the root probably intensifying the overfillingby the radicular loss. The election treatment plan consists in removing filling materials of the root, determination of a new root length and instrumentation.Periodical monthly changes of calcium hydroxide and polyethyleneglycol associated were carried out. After this period a root reabsorption stagnation process was verified radiographically, presenting a significant improvementof tissue repair allowing root filling. The radiographic control shows success even after four years of treatment conclusion.

Based on this assumption, we suspected that hair dye dermatitis was occurring more frequently than reported in the literature. Consumer complaint-based data...... in the health care system. The frequency of allergic contact dermatitis resulting from hair dye is likely to be underestimated. New methods to survey the frequency of adverse reactions should be considered.......Severe facial and scalp dermatitis following the use of permanent hair dyes has been reported in several cases. Para-phenylenediamine (PPD) is known as a potent contact allergen, and PPD is allowed in hair dye at a concentration of 6%. Hair dye reactions are usually diagnosed by the patients...

    Aggressive periodontitis is a rare form of periodontal disease and it can involve both the deciduous dentition and the permanent one. It causes a rapid loss of periodontal attachment. The paper aims to describe two cases of severe generalized prepubertal periodontitis: the first child doesn't suffer from neither systemic diseases nor alteration of functionality of polymorphonuclear and periodontal disease involved both his deciduous dentition and the first permanent molars. The second child had a deficiency of functionality of polymorphonuclear but periodontal disease involved only primary dentition thanks to his immediate improvement of home dental hygiene. This comparison shows the importance of early diagnosis and especially of optimal dental oral hygiene. Infant healthcare professionals, as pediatric dentists and pediatricians, should have the necessary knowledge for early and correct diagnosis and clinical management of disease. PMID:25573711

    Lesbians and gay men are turning to the courts to recognize their family relationships. In this article every reported court decision where a lesbian or gay couple has successfully completed a second-parent adoption is reviewed to analyze the presentation and judicial analysis of the petitioning parties in conjunction with the current debates within family theory. Traditional family theorists argue that the contemporary family is in transition but will always be recognizable as the traditional family; postmodern theorists argue that the traditional "family" is a fiction. Results from this study indicate that judges in second-parent adoption cases rely on a traditional definition and vision of the family in evaluating the gay and lesbian petitioners before them.

    Directory of Open Access Journals (Sweden)

    C. Varetti

    2012-01-01

    Full Text Available Introduction. "Genetic errors" with malformations and hormonal alterations result in a broad spectrum of disorders of sexual identity difficult to classify for etiopathogenesis and anatomy. Male pseudohermaphroditism (PEM is the result of defects in masculinisation, persistence of mullerian ducts or genital malformations. In these patients, there is always a 46 XY karyotype, male gonads with the external genitalia and phenotype completely or partially female. The authors describe 2 cases of PEM. Patients and Methods. RS and HNA, 9 and 15 years old. Both had 46 XY karyotype and female phenotype with the presence of penile clitoris and small vagina. The urethral meatus was positioned at the base of the penile clitoris and upper vagina and testicles, were located at the proximal portion of the inguinal canal.Patients were subjected to MRI showing absence of uterus and ovaries. The endoscopy described a small vagina dead-end about 4-5 cm long. Complete resection of the vagina, bilateral orchiopexy, correction of perineal hypospadias with urethral tubulization, reconstruction of the scrotum, with the results of penoscrotal hypospadias were performed. Discussion. Sexual differentiation is the process between VII and XII weeks of gestational age leading to formation of male or female fetus from embryo potentially bisexual. Brain Code gender is bipolar: male or female. In the sexual disorders there is a discrepancy between anatomical sex and the brain code. Genital malformation with a direct mechanism (external genitalia and indirect (prenatal pathological imprinting on all the receptors of target organs may exacerbate the brain deterioration of the code resulting in disease patterns difficult to manage according psychological and surgical aspects. Conclusions. Pediatric Surgeon plays a key role in the treatment of genital anomalies. Valutation of pelvic-perineal anatomy is important for the choice of sexual phenotype and related surgical strategy

    2009-01-01

    In 1886 Pierre Marie used the term "acromegaly" for the first time and gave a full description of the characteristic clinical picture. However several others had already given clear clinical descriptions before him and sometimes had given the disease other names. After 1886, it gradually became clear that pituitary enlargement (caused by a pituitary adenoma) was the cause and not the consequence of acromegaly, as initially thought. Pituitary adenomas could be found in the great majority of cases. It also became clear that acromegaly and gigantism were the same disease but occurring at different stages of life and not different diseases as initially thought. At the end of the 19th and beginning of the 20th century most information was derived from case descriptions and post-mortem examinations of patients with acromegaly or (famous) patients with gigantism. The stage was set for further research into the pathogenesis, diagnosis and therapy of acromegaly and gigantism. PMID:18683056

    Full Text Available Background: Stroke is a leading cause of disability in adults. Following stroke, 60% of people report needing help with everyday activities, and 80% report having very few meaningful activities. These restrictions often continue for years. This study explored the efficacy of Occupational Performance Coaching for stroke survivors (OPC-Stroke on the participation level of adults in the later stage of stroke rehabilitation. Method: A descriptive case study design was used. One participant in the later stages of rehabilitation was recruited. Outcome measures for participation, goal performance and satisfaction, and emotional well-being were administered pre and postintervention to observe for direction of change. A semi-structured interview was carried out postintervention to explore the participant’s experiences of the intervention. Results: The participant who took part in the study reported improvement with his goal performance and satisfaction. However, the level of participation did not improve and emotional well-being decreased. Qualitative data revealed an appreciation of the intervention and a recommendation of the intervention for others. Conclusion: OPC-Stroke was valued by the participant and shows promise for improving goal performance and satisfaction. Further research is necessary to determine the potential efficacy of OPC-Stroke in later stages of rehabilitation.

    Full Text Available Numerical description of the groundwater levels change due to the re- and discharge of the adjacent surface water bodies – problems and case studies. The water exchange between the surface water bodies (rivers, lakes, seas, dams, etc. and adjacent water-bearing beds is possible if a hydraulic connection between them exists. The change of the levels of the first ones causes corresponding changes of the levels of the aquifers in the surrounding territories and vice versa.

  15. Corpus–Based Lexicographical Descriptions with a Special Focus on Pragmatics: The Case of the Slovene Lexical Database

    Directory of Open Access Journals (Sweden)

    Mojca Šorli

    2013-05-01

    Full Text Available The present paper focuses on ways in which the pragmatic (functional meaning that arises from various contextual features, known in corpus linguistics as semantic prosody, can become an integral part of lexicographical descriptions as they are represented in the Slovene Lexical Database (SLD. This is particularly important for the treatment of phraseology and idiomatics. First, the theoretical background is provided, with the focus on the prototype theory and its practical implications for monolingual lexicography. A parallel is drawn with the model of meaning analysis in the SLD. The second part begins with a brief introduction to semantic prosody and continues with an analysis of monolingual meaning descriptions in the SLD against a number of authentic corpus examples, investigating how their pragmatic components have been identified. The analysis of corpus data shows that pragmatics is an important contributor to the process of sense discrimination in works of lexical and lexicographic relevance.

    Vibrio cholerae non-O1 serogroup (VCNO) bacteraemia is a severe condition with a high case-fatality rate. We report three cases diagnosed in the Netherlands, identified during a national microbiological congress, and provide a literature review on VCNO bacteraemia. A search strategy including synonyms for 'VCNO' and 'bacteraemia' was applied to PubMed, Medline, Web of Science and Embase databases. The three cases were reported in elderly male patients after fish consumption and/or surface water contact. The literature search yielded 82 case reports on 90 cases and six case series. Thirty case reports were from Asia (30/90; 33%), concerned males (67/90; 74%), and around one third (38/90; 42%) involved a history of alcohol abuse and/or liver cirrhosis The presenting symptom often was gastroenteritis (47/90; 52%) which occurred after seafood consumption in 32% of the cases (15/47).Aside from the most frequent symptom being fever, results of case series concurred with these findings. Published cases also included rare presentations e.g. endophthalmitis and neonatal meningitis. Based on the limited data available, cephalosporins seemed the most effective treatment. Although mainly reported in Asia, VCNO bacteraemia occurs worldwide. While some risk factors for VCNO were identified in this study, the source of infection remains often unclear. Clinical presentation may vary greatly and therefore a quick microbiological diagnosis is indispensable. PMID:27104237

    Epidemiologic data on phocomelia are scarce. This study presents an epidemiologic analysis of the largest series of phocomelia cases known to date. Data were provided by 19 birth defect surveillance programs, all members of the International Clearinghouse for Birth Defects Surveillance and Research. Depending on the program, data corresponded to a period from 1968 through 2006. A total of 22,740,933 live births, stillbirths and, for some programs, elective terminations of pregnancy for fetal anomaly (ETOPFA) were monitored. After a detailed review of clinical data, only true phocomelia cases were included. Descriptive data are presented and additional analyses compared isolated cases with those with multiple congenital anomalies (MCA), excluding syndromes. We also briefly compared congenital anomalies associated with nonsyndromic phocomelia with those presented with amelia, another rare severe congenital limb defect. A total of 141 phocomelia cases registered gave an overall total prevalence of 0.62 per 100,000 births (95% confidence interval: 0.52–0.73). Three programs (Australia Victoria, South America ECLAMC, Italy North East) had significantly different prevalence estimates. Most cases (53.2%) had isolated phocomelia, while 9.9% had syndromes. Most nonsyndromic cases were monomelic (55.9%), with an excess of left (64.9%) and upper limb (64.9%) involvement. Most nonsyndromic cases (66.9%) were live births; most isolated cases (57.9%) weighed more than 2,499 g; most MCA (60.7%) weighed less than 2,500 g, and were more likely stillbirths (30.8%) or ETOPFA (15.4%) than isolated cases. The most common associated defects were musculoskeletal, cardiac, and intestinal. Epidemiological differences between phocomelia and amelia highlighted possible differences in their causes.

    2013-02-01

    Ornithodoros brasiliensis, also known as the "mouro" tick, is an argasid tick found exclusively in the southern Brazilian highlands. O. brasiliensis parasitism is frequently associated with severe symptoms directly induced by the tick bite, a condition compatible with the definition of tick toxicosis. The objectives of this work include (i) the determination of the distribution of O. brasiliensis in farms located in the tick-endemic region, (ii) the description of the characteristics of O. brasiliensis habitats, (iii) the analysis of risk factors associated with O. brasiliensis, and (iv) the retrospective description of cases of human and animal parasitism by O. brasiliensis. Of the 30 farms included in this study, O. brasiliensis was identified on 5 farms (frequency 16.7%), in which several ticks found in high density buried in soil were collected. Information regarding the tick habitats and the local population was recorded. The data indicated that O. brasiliensis feeds on humans, dogs, armadillos (Dasypus hybridus), and possibly skunks (Conepatus chinga). The analysis of risk factors indicated that the presence of house basements with an unpaved (natural soil) floor on farms and insufficient sanitary conditions significantly enhanced the probability of identifying O. brasiliensis. Additionally, we describe retrospectively cases of tick parasitism in 28 humans and 11 dogs including the most common symptoms associated with tick toxicosis. This is the first study concerning O. brasiliensis epidemiology, distribution, and habitat, and the report represents the most comprehensive characterization of Ornithodoros bite-associated toxicosis syndrome.

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    We consider a binary erasure version of the n-channel multiple descriptions problem with symmetric descriptions, i.e., the rates of the n descriptions are the same and the distortion constraint depends only on the number of messages received. We consider the case where there is no excess rate for every k out of n descriptions. Our goal is to characterize the achievable distortions D_1, D_2,...,D_n. We measure the fidelity of reconstruction using two distortion criteria: an average-case distortion criterion, under which distortion is measured by taking the average of the per-letter distortion over all source sequences, and a worst-case distortion criterion, under which distortion is measured by taking the maximum of the per-letter distortion over all source sequences. We present achievability schemes, based on random binning for average-case distortion and systematic MDS (maximum distance separable) codes for worst-case distortion, and prove optimality results for the corresponding achievable distortion region...

  6. Pine mouth (pine nut) syndrome: description of the toxidrome, preliminary case definition, and best evidence regarding an apparent etiology.

    Munk, Marc-David

    2012-11-01

    Pine mouth syndrome (PMS), otherwise known as pine nut syndrome, is a relatively new condition. At least several thousand cases have now been described in the literature. The author describes the PMS toxidrome, offers a preliminary case definition, and discusses current best evidence regarding the etiology and risk factors related to the development of PMS.A clinically compatible case of PMS must include taste disturbance, usually characterized as bitter or metallic, following the ingestion of affected pine nuts by 1 to 3 days. Affected nuts would appear to include all, or some portion, of nuts harvested from species Pinus armandii (Chinese white pine), but could include nuts from other species. The specific toxin that is apparently present in affected nuts has not yet been isolated, and the mechanism of toxicity and factors determining PMS susceptibility need to be further detailed. There are no proven therapies for PMS. The only treatment is to cease ingesting implicated nuts and to wait for symptoms to abate.

    Chemically Induced Dynamic Nuclear Polarization (CIDNP) is an efficient method of creating non-equilibrium polarization of nuclear spins by using chemical reactions, which have radical pairs as intermediates. The CIDNP effect originates from (i) electron spin-selective recombination of radical pairs and (ii) the dependence of the inter-system crossing rate in radical pairs on the state of magnetic nuclei. The CIDNP effect can be investigated by using Nuclear Magnetic Resonance (NMR) methods. The gain from CIDNP is then two-fold: it allows one to obtain considerable amplification of NMR signals; in addition, it provides a very useful tool for investigating elusive radicals and radical pairs. While the mechanisms of the CIDNP effect in liquids are well established and understood, detailed analysis of solid-state CIDNP mechanisms still remains challenging; likewise a common theoretical frame for the description of CIDNP in both solids and liquids is missing. Difficulties in understanding the spin dynamics that lead to the CIDNP effect in the solid-state case are caused by the anisotropy of spin interactions, which increase the complexity of spin evolution. In this work, we propose to analyze CIDNP in terms of level crossing phenomena, namely, to attribute features in the CIDNP magnetic field dependence to Level Crossings (LCs) and Level Anti-Crossings (LACs) in a radical pair. This approach allows one to describe liquid-state CIDNP; the same holds for the solid-state case where anisotropic interactions play a significant role in CIDNP formation. In solids, features arise predominantly from LACs, since in most cases anisotropic couplings result in perturbations, which turn LCs into LACs. We have interpreted the CIDNP mechanisms in terms of the LC/LAC concept. This consideration allows one to find analytical expressions for a wide magnetic field range, where several different mechanisms are operative; furthermore, the LAC description gives a way to determine CIDNP sign

    Candida nivariensis is a new emergent agent related to human infections in the vaginal tract and other localizations, but the phenotypic characteristics are very similar to Candida glabrata and can be misidentified and underdiagnosed. We described four cases of vulvovaginitis identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and confirmed the results with PCR amplification and sequencing of the entire ITS genomic region (ITS1, ITS2 and 5.8 rRNA). We reinforce the need for new diagnostic tools for the correct identification of yeast infections. PMID:26708316

    Persistent primitive hepatic venous plexus is an anomaly of the systemic venous return characterised by postnatal persistence of the foetal intrahepatic venous drainage. Scimitar syndrome is a condition that consists of partial anomalous pulmonary venous return of the right pulmonary venous drainage into the systemic veins, associated with pulmonary artery hypoplasia with the underdeveloped right lung, pulmonary sequestration, and cardiac malposition. Both conditions are rare and together have been rarely described in the literature. We report the first case of this combination of lesions imaged by cardiac magnetic resonance imaging with a three-dimensional reconstruction and reviewed the literature to characterise this uncommon combination.

    1981-02-01

    Peroral application of iron salts in various types of anemia was previously considered atoxic. The increased use of iron has, however, led to an increasing number of poisoning in children, taking iron tablets for candy. There have only been reported a few number of spontaneous intoxications in animals, but experimentally it has been possible to produce fatal intoxications in various kinds of animal species. The clinical findings are quite similar in the various animals, starting with vomiting, bloody diarrhoea and metabolic acidosis. If the intoxication is severe, shock and coma may develop, and death occurs quite soon. The histological findings are also similar in the various animals, varying from erosions of the tops of the villi to necrosis of the mucosal membrane of the jejunum. Degenerative changes in the liver as well as in the kidney are seen in several cases. The mentioned case was a horse given about 475 g ferro fumarate over a period of 5 days. The horse developed the classic clinical picture and death occurred on day 7. The diagnosis was confirmed by very high levels of iron in the liver, kidney and serum. The blood values of the enzymes ASAT and gamma GT were extremely high as a sign of a severe damage of the liver.

    Although most insulinomas are located in the pancreas, very rare ectopic cases have been described in the spleen, perisplenic tissue, duodenohepatic ligament, and adjacent to the ligament of Treitz. Moreover, three cases located in the duodenum have also been reported in the English literature. Ectopic insulinomas represent challenging neoplasms with clinical implications mainly due to the difficulties in their pre-operatory diagnosis and localization. In the present paper, we describe the fourth ectopic duodenal insulinoma so far reported. A 75-year-old woman presented at clinical observation due to neuroglycopenic symptoms that disappeared after glucose intake. Tumor was localized in the second portion of the duodenum in front of the papilla of Vater and was surgically enucleated. Microscopically, it was composed of monomorphic cells with eosinophilic cytoplasm arranged in trabecular and lobular patterns and diffusely positive for insulin, proinsulin, amylin, and PDX1. About 30 % of tumor cells also showed immunoreactivity for somatostatin, while no positivity for glucagon, pancreatic polypeptide, gastrin, serotonin, and somatostatin receptor subtype 2A was found. The Ki67 proliferative index was 1 %. We have also reviewed the literature on this topic to give the reader a comprehensive overview of this very rare tumor type. PMID:24006218

  15. Description of survival data extended to the case of competing risks: a teaching approach based on frequency tables

    Directory of Open Access Journals (Sweden)

    Davide Paolo Bernasconi

    2013-10-01

    Full Text Available Survival analysis is a powerful statistical tool to study failure-time data. In introductory courses students learn how to describe right-censored survival time data using the product-limit estimator of the survival function on a given end-point relying on a product of conditional survival probabilities. In the case of a composite end-point, the next step is to account for the presence of competing risks. The complement to one of the survival function is decomposed into the sum of cause-specific incidences, which are obtained as sum of unconditional probabilities due to the single competing risk. However, this algebraic decomposition is not straightforward, given the difference between the structure of the involved estimators. In addition, one is tempted to use the Kaplan-Meier estimator, leading to an erroneous decomposition of the overall incidence. Here we discuss a simple reinterpretation of the Kaplan-Meier formula in terms of sum of non-conditional probabilities of developing the end-point in time, adjusted for the presence of censoring. This approach could be used for describing survival data through simple frequency tables which are directly generalized to the case of competing risks. In addition, it makes clear how the estimation of the single cause-specific incidence through the Kaplan-Meier estimator, simply considering the occurrence of competing events as censored data, leads to an overestimation of the cause-specific incidence. Two examples are provided to support the explanation: the first one, could help to clarify the procedure described by the formulas; the second one, simulates real data in order to present graphically the results.

    The objective of this study was to describe the clinical and immunological characteristics of maternal autoimmune-mediated fetal congenital heart block (CHB) in a cohort of pregnant women from an autoimmune disease pregnancy clinic. This is a retrospective observational study of all women presenting with CHB in our autoimmune disease pregnancy clinic from January 1997 to December 2014. In addition, perinatal outcome is also described. Fourteen patients accounting for 18 fetuses with CHB were identified. The median age was 32.5 years (range, 22-40). Seven (50 %) patients had Sjögren's syndrome, and the remaining seven were asymptomatic carriers of autoantibodies. All patients had anti-Ro/SSA antibodies, and 11/13 (85 %) had anti-La/SSB antibodies. The median gestational age at the time of CHB was 22 weeks (range 18-28). Complete third degree CHB was detected in 12 (67 %). Seven cases of CHB were treated with dexamethasone, two with ritodrine, and one with the association of dexamethasone, ritodrine, and terbutaline. In 9 (50 %) cases that presented with, or developed, very poor prognosis factors, such as a ventricular rate below 50-55 bpm and/or the presence of fetal hydrops, parents opted for the termination of pregnancy, after dedicated counseling. Finally, there were nine newborns (seven males [78 %]) with median age at delivery of 37 weeks (range, 32-39). A definitive epicardial pacemaker was placed in six newborns, four of them within 2 weeks of life. CHB is a severe complication related to maternal anti-Ro/SSA and anti-La/SSB antibodies. Our results confirm previous data showing that therapy is ineffective, and most of the surviving patients will require neonatal pacemaker.

    Full Text Available En los últimos años se ha incrementado la utilización de sustancias de relleno facial con fines estéticos. Estos productos, originalmente considerados inertes, se asocian con diversos efectos adversos localizados alrededor del sitio de la aplicación. Describimos a 5 mujeres con antecedentes de inyecciones de sustancia de relleno facial que presentaron como síntoma inicial angioedema facial duro y persistente seguido por la aparición de nódulos subcutáneos. Todas las pacientes fueron derivadas al servicio de alergia por sospecha de angioedema de causa alérgica sin respuesta al tratamiento con antihistamínicos. El angioedema inició 27.6 meses (1 a 48 luego de la inyección del producto, y las pacientes evolucionaron con brotes y remisiones que fueron tratados con corticoides orales y en 2 oportunidades con inyecciones locales. El tiempo medio desde el inicio de los síntomas hasta la remisión del angioedema fue 8.75 meses (1 a 24. A octubre de 2009 cuatro pacientes se mantuvieron en remisión persistente, luego de un seguimiento clínico de 24.5 meses (7 a 36. Una paciente continúa con exacerbaciones luego de 11 meses de iniciados los síntomas. Las sustancias de relleno facial pueden producir angioedema como evento adverso y deben ser consideradas en el diagnóstico diferencial del angioedema persistente. Sólo responden al tratamiento con esteroides y en algunos casos esteroides dependientes, con ciclosporina. La frecuencia de angioedema por rellenos faciales entre pacientes con angioedema asistidos en la Unidad de Asma, Alergia e Inmunología Clínica fue del 0.5%.The use of fillers for cosmetic purposes is becoming increasingly frequent.

    Full Text Available Abstract Aim To describe the development of a dementia research registry, outlining the conceptual, practical and ethical challenges, and to report initial experiences of recruiting people with dementia to it from primary and secondary care. Background Women, the oldest old and ethnic minorities have been under-represented in clinical trials in dementia. Such under-representation biases estimates of absolute effect, absolute harm and cost-effectiveness. Research on dementia should include patient populations that more exactly reflect the population at risk. One of the impediments to this is the lack of a suitable tool for identification of patients suitable for studies. Construction & contents A technology development methodology was used to develop a registry of people with dementia and their carers. This involved phases of modelling and prototype creation, 'bench testing' the prototype with experts and then 'field testing' the refined prototype in exemplar sites. The evaluation of the field testing described here is based on a case study methodology. Utility This case study suggests that construction and population of a dementia research registry is feasible, but initial development is complex because of the ethical and organisational difficulties. Recruitment from primary care is particularly costly in terms of staff time and only identifies a very small number of people with dementia who were not already known to specialist services. Recruiting people with dementia through secondary care is a resource intensive process that takes up to six months to complete. Identifying the components of a minimum dataset was easy but its usefulness for pre-screening potential research populations has yet to be established. Acceptance rates are very high in the first clinic to recruit to the registry, but this may reflect the efforts of registry 'champions'. Discussion and Conclusions Easier recruitment may perpetuate potential selection biases and we are

    Full Text Available Abstract Background More than a hundred terms, often with unclear definitions and varying emphases, are used by health research and practice communities across the world who are interested in getting the best possible evidence applied (e.g., knowledge translation, implementation science, diffusion of innovations, and technology transfer. This makes finding published evidence difficult and can result in reduced, misinterpreted, or challenging interactions among professionals. Open dialogue and interaction among various professionals is needed to achieve consolidation of vocabulary. We use case report methods to describe how we sought to build an online tool to present the range of terms and facilitate the dialogue process across groups and disciplines interested in harnessing research evidence for healthcare. Methods We used a wiki platform from Wikispaces to present the problem of terminology and make a case and opportunity for collaboration on usage. Wikis are web sites where communities of users can collaborate online to build content and discuss progress. We gathered terms related to getting research into practice, sought published definitions, and posted these on the wiki (WhatisKT http://whatiskt.wikispaces.com/. We built the wiki in mid-2008 and promoted it through various groups and publications. This report describes the content of the site, our promotion efforts, use of the site, and how the site was used for collaboration up to the end of 2011. Results The WhatisKT wiki site now includes more than 120 pages. Traffic to the site has increased substantially from an average of 200 monthly visits in 2008 to 1700 in 2011. Visitors from 143 countries viewed the wiki in 2011, compared with 12 countries in 2008. However, most use has been limited to short term accesses of about 40 seconds per visit, and discussion of consolidation and solidifying terminology is conspicuously absent. Conclusions Although considerable interest exists in the

    Full Text Available This report presents a case of two smooth muscle hamartomas of the stomach in a 10-year-old male Boxer. The clinical history of the animal was of chronic vomiting, weight loss, and intermittent gastric distension, and it died because of chronic and congestive heart failure. Gross, histology, and immunohistochemistry (IHC exams were performed. On necropsy, in the pyloric region of the stomach, two closely related polypoid growths between 10 and 15 mm in diameter were identified. On the cut sections, both polyps presented white to gray color, with homogenous architecture and well-defined limits. The thickness of the submucosal layer was seen to be increased to 1 cm. No other gastric alterations were identified by the necropsy exam. Histologically, both masses growth consisted of hyperplastic glands lined by foveolar epithelium, arranged in a papillary or branching pattern, and supported by a core of well-vascularised and marked smooth muscle tissue interspersed between glands. No dysplastic cells and mitotic figures were observed in these lesions. Immunohistochemistry revealed a strong cytoplasm labelling for smooth muscle actin of the bundles around the mucosal glands. To our knowledge, this is the first report of smooth muscle hamartomas mimicking multiple gastric polyps in dogs.

    Full Text Available Bowel stent insertion has a variety of complications one major of which is colonic perforation. The purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. The first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction. Although the procedure resulted in complete relief of patient symptoms, but he returned with signs of peritonitis 10 days after the stent placement. A perforation was found at rectosigmoid junction on laparotomy. The second patient was a 60 year-old man who underwent a successful stent placement and returned 3 months later with a complaint of abdominal pain that showed up to be due to a rectal perforation on investigations. In conclusion, bowel perforation following stent placement can be a major complication, so close follow-up is necessary to detect it as soon as possible and prevent it from becoming an irreparable complication.

    Full Text Available Two young dogs were presented for the evaluation of an abnormally haired appearance of both eyes since adoption. In one dog, the lesions were symmetrical and appeared as disorganized skin tissue located on the cutaneous aspect of the lateral portion of both lower eyelids, and continuing to the palpebral and the bulbar conjunctiva, thus forming continuous lesions. In the other dog, a similar lesion was present in the right eye (OD, but the lesion of the left eye (OS was of discontinuous, disorganized skin tissue located midway on the lower eyelid and on the lateral bulbar conjunctiva. The lesions were surgically removed and routinely processed for histopathological analysis. Definitive diagnosis was conjunctivo-palpebral dermoids for each dog. Dermoids are usually considered to be choristoma (normal tissue in an abnormal location when they are located on the ocular surface (cornea and/or conjunctiva and as hamartoma when located on the palpebral skin. The lesion presentation in these two dogs reveals that names of “choristoma” alone or “hamartoma” alone are not accurate to depict the continuous, composite, conjunctivo-palpebral dermoids. These cases suggest that choristoma and hamartoma might develop subsequently from the same abnormal event during the embryonic development, which means that the lesion location might be the only difference between the two terms.

    Mitral regurgitation may result from left ventricular dilatation and cause progression of heart failure. Percutaneous techniques for mitral valve repair are under development. Techniques utilizing a trans-coronary venous approach exploit the anatomical relationship between the mitral annulus and the venous system of the heart. The coronary sinus, great cardiac vein and the origin of the anterior interventricular vein surround the posterior mitral annulus. This enables percutaneous approaches to annuloplasty for mitral regurgitation. Devices can be implanted into the coronary veins that modify the shape and size of the mitral annulus. We present a case of ischaemic mitral regurgitation successfully treated by use of a percutaneous approach, the Carillon Mitral Contour System. Significant reduction of the mitral regurgitation jet was observed. The patient was discharged 4 days after the procedure. During the follow-up visits, the patient showed an improved general condition and increased exercise capacity. Procedural steps are shown in detail and the current status of the coronary sinus based technique is discussed. Percutaneous techniques for mitral valve repair may be an attractive alternative to cardiac surgery in heart failure patients with secondary mitral regurgitation. The Carillon Mitral Contour System is under ongoing clinical evaluation in the AMADEUS trial. PMID:17436155

  5. First description of an acinic cell carcinoma of the breast in a BRCA1 mutation carrier: a case report

    International Nuclear Information System (INIS)

    Acinic cell carcinoma (ACC) is a rare malignant epithelial neoplasm characterized by the presence of malignant tubular acinar exocrine gland structures. Diagnosis is generally made in salivary glands and in the pancreas. ACC of the breast has been reported in few cases only. Carriers of inherited mutations in the BRCA1 gene are prone to the development of breast cancer, mainly invasive ductal or medullary type carcinomas. We describe for the first time a BRCA1 mutation carrier with a diagnosis of ACC of the breast. The patient developed an invasive ductal carcinoma (IDC) at the age of 40 years and an ACC in the contralateral breast at 44 years. Immunohistochemical examination of the ACC revealed a triple negative status (i.e., negativity for estrogen receptor, progesterone receptor and HER2 protein) and positivity for p53. Using a combination of loss of heterozygosity (LOH) and sequencing analyses, the loss of the wild-type BRCA1 allele was detected in both the ACC and the IDC. In addition, two different somatic TP53 mutations, one in the ACC only and another one in the IDC only, were observed. Both the immunohistochemical and molecular features observed in the ACC are typical of BRCA1-associated breast cancers and suggest an involvement of the patient’s germline mutation in the disease. The occurrence of rare histological types of breast cancers, including malignant phyllodes tumor, atypical medullary carcinoma and metaplastic carcinoma, in BRCA1 mutation carriers has been already reported. Our findings further broaden the spectrum of BRCA1-associated breast malignancies

    Description Logics (DLs) are a well-investigated family of logic-based knowledge representation formalisms, which can be used to represent the conceptual knowledge of an application domain in a structured and formally well-understood way. They are employed in various application domains, such as natural language processing, configuration, and databases, but their most notable success so far is the adoption of the DL-based language OWL as standard ontology language for the semantic web.

    [Objective] To descriptively analyze the epidemical and clinical characteristics of lower lumbar (L3 to L5) fractures. [Method] We analyzed the sex,age,causes,associated injuries,and other information of all the lower lumbar fracture cases treated from Sep. 1st ,2006 to Jun. 30th ,2010 in Songjiang Division of our hospital, retrospectively. All the single-level fractures were classified by the AO-classification system, whereas the Tang Sanyuans classification for all the multiple-level spinal fractures, and each level was classified according to the AO-classification system. [Result] Totally we obtained 182 cases of lower lumbar vertebral factures. There were 98 males and 84 females. The ratio of sex ( male: female) was 1.2. The average age was 50. 6 ± 19. 7 years old. There was a linear correlation between age and the ratio of sex and the cause of fracture. One hundred and sixteen fractures of L3 vertebrae,74 of L4 and 22 of L5 were involved. There were 102 cases (56. 0% ) of single-level fractures and 80 cases (44.0% ) of multiple-level fractures, and the latter was more common in non-traumatic ones. One hundred and thirty-two cases of traumatic lower lumbar fractures had a significant lower average age compared with non-traumatic cases. The risk in the males was 3. 95 times greater than the females. Axial compressive violence was the main cause of the fractures, among which there were 136 levels (93. 2% ) of type-A and 6 levels (4. 1% ) of type-Cl. No obvious difference was found between each level. There were 50 cases (37. 9% ) of traumatic multiple-level spinal fractures,21 (42. 0% ) of type-I and 29 (58.0%) of type-II. Forty-one cases (31. 1%) were complicated with thoracolumbar (Tn - L, ) fractures,8 (6. 1%) with level above Tlo. Fifty-six cases (42. 4% ) were associated with injuries in other sites,of which the most commonly seen were limbs fractures (41 cases,31. 1% ) .followed by thoracic injuries (25 cases,18.9% ).

    Following of the emergence of Zika virus in Brazil in 2015, an epidemiological surveillance system was quickly implemented in the French overseas Territories of America (FTA) according to previous experience with dengue and chikungunya and has detected first cases of Zika. General practitioners and medical microbiologists were invited to report all clinically suspected cases of Zika, laboratory investigations were systematically conducted (RT-PCR). On 18 December, the first autochthonous case of Zika virus infection was confirmed by RT-PCR on French Guiana and Martinique, indicating introduction of Zika virus in FTA. The viral circulation of Zika virus was then also confirmed on Guadeloupe and Saint-Martin. We report here early findings on 203 confirmed cases of Zika virus infection identified by RT-PCR or seroneutralisation on Martinique Island between 24 November 2015 and 20 January 2016. All cases were investigated. Common clinical signs were observed (maculopapular rash, arthralgia, fever, myalgia and conjunctival hyperaemia) among these patients, but the rash, the foundation of our case definition, may be absent in a significant proportion of patients (16%). These results are important for the implementation of a suspected case definition, the main tool for epidemiological surveillance, in territories that may be affected by ZIKV emergence, including Europe.

    B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma, is a diagnostic provisional category in the World Health Organization (WHO) 2008 classification of lymphomas. This category was designed as a measure to accommodate borderline cases that cannot be reliably classified into a single distinct disease entity after all available morphological, immunophenotypical and molecular studies have been performed. Typically, these cases share features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma, or include characteristics of both lymphomas. The rarity of such cases poses a tremendous challenge to both pathologists and oncologists because its differential diagnosis has direct implications for management strategies. In this study, we present 10 cases of B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma and have organized the criteria described by the WHO into four patterns along with detailed clinical, morphological and immunophenotypic characterization and outcome data. Our findings show a male preponderance, median age of 37 years and a mediastinal presentation in 80% of cases. All cases expressed at least two markers associated with B-cell lineage and good response to combination chemotherapy currently employed for non-Hodgkin lymphomas.

    Teleology descriptions capture the purpose of an entity, mechanism, or activity with which they are associated. These descriptions can be used in explanation, diagnosis, and design reuse. We describe a technique for acquiring teleological descriptions expressed in the teleology language TeD. Acquisition occurs during design by observing design modifications and design verification. We demonstrate the acquisition technique in an electronic circuit design.

    Full Text Available Pregnancy implanted outside the endometrial cavity constitutes ectopic gestation. The reproductive performance can be poor following an ectopic pregnancy. The purpose of the study is to emphasize the importance of public awareness about the need for early reporting to hospital in doubtful cases, to analyze the risk factors for ectopic, to study the role of βHCG estimation and transvaginal sonography in early detection in order to preserve the fallopian tube by medical therapy and/or to do early elective surgery preventing emergency laparotomy and death from ectopic pregnancy. METHODOLOGY: All cases of ectopic gestations managed in a tertiary care hospital for a period of one year is reviewed, roughly around 70 cases. The objectives were to analyze demographic characteristics, risk factors, methods of diagnosis and to evaluate the protocol for ectopic management in the hospital. RESULTS: The study showed that the maximum number of ectopic was seen in the 26 - 30 age group and more commonly among multies. Maximum number of ectopic cases is seen between 5.1 to 6 weeks and 80% of the cases are seen in ≤8 weeks. 42/70 patients showed one or more risk factors like previous history of ectopic, LSCS, infertility treatment, sterilization and use of IUCD.82.9% patients presented either with pain alone or pain along with spotting/bleeding p/v. Earlier, majority of the cases were reported after tubal rupture resulting in shock, which sometimes even lead to death. In the present scenario, however, only 2 patients developed hypotension, 11 out of 70 alone required blood transfusion and none required laparotomy. Majority of cases of unruptured ectopic (83% showed <66% rise in βHCG in 48 hours. Pelvic ultrasound and serum βHCG estimation has revolutionized the diagnostic proce ss of ectopic pregnancy enabling detection in the unruptured stage itself in 50% of the cases and the rest in early stages of rupture. In most cases, medical line of management with

    Full Text Available Introduction. The seizure propagation phenomenon by inducing remote symptoms brings several difficulties in finding the seizure onset and delineating the epileptic network which should be taken into consideration in epilepsy surgery. By demonstrating a difficult (MRI negative epilepsy surgery case explored with invasive presurgical evaluation we highlight the importance to recognise the secondary sensory area and to explore the the parieto-opercular-insular-medial frontal network in certain cases. A further conclusion is the consideration of the redistributory role of the insula as a special structure in the cerebral connectome, having a role in epileptic network organisation.

    Full Text Available Phlegmonous gastritis is a rare bacterial infection of the gastric wall, which progress rapidly. It is characterized by a purulent inflammation that can affect the entire gastrointestinal tract and presents a high mortality rate. We are reporting a case of phlegmonous gastritis in an HIV-seropositive man successfully treated with antibiotics. Moreover, a review of the English and Spanish literature is carried out, from 1980 to the present time. The most frequently involved microorganism is Streptococcus spp. (57 %, but the polimicrobial infection is also frequent (17 %. The most important symptom is the intensive epigastric pain associated with vomits and most cases were diagnosed by CT and/or fibrogastroscopy. There are many existing risk factors described. The main one is the immunesuppression, although in 40 % of the cases no risk factors were identified. The global mortality is 27 % without identifying significant differences between antibiotics and surgical treatment, for that reason it is recommended to initiate antibiotic treatment right from the beginning and postponing surgery for the refractory cases and complications.

    2010-09-01

    African tick-bite fever (ATBF) is a newly described spotted fever rickettsiosis that frequently presents with multiple eschars in travelers returning from sub-Saharan Africa and, to a lesser extent, from the West Indies. It is caused by the bite of an infected Amblyomma tick, whose hunting habits explain the typical presence of multiple inoculation skin lesions and the occurrence of clustered cases. The etiological agent of ATBF is Rickettsia africae, an emerging tick-borne pathogenic bacterium. We describe herein a cluster of five cases of ATBF occurring in Swiss travelers returning from South Africa. The co-incidental infections in these five patients and the presence of multiple inoculation eschars, two features pathognomonic of this rickettsial disease, suggested the diagnosis of ATBF. Indeed, the presence of at least one inoculation eschar is observed in 53-100% of cases and multiple eschars in 21-54%. Two patients presented regional lymphadenitis and one a mild local lymphangitis. Though a cutaneous rash is described in 15-46% of cases, no rash was observed in our series. ATBF was confirmed by serology. Thus, ATBF has recently emerged as one of the most important causes of flu-like illness in travelers returning from Southern Africa. The presence of one or multiple eschars of inoculation is an important clinical clue to the diagnosis. It can be confirmed by serology or by PCR of a biopsy of the eschar. Culture can also be done in reference laboratories. Dermatologists and primary care physicians should know this clinical entity, since an inexpensive and efficient treatment is available.

    Full Text Available Abstract Background We present a descriptive and retrospective analysis of revision total hip arthroplasties (THA using the MRP-TITAN stem (Peter Brehm, Weisendorf, GER with distal diaphyseal fixation and metaphyseal defect augmentation. Our hypothesis was that the metaphyseal defect augmentation (Impaction Bone Grafting improves the stem survival. Methods We retrospectively analyzed the aggregated and anonymized data of 243 femoral stem revisions. 68 patients with 70 implants (28.8% received an allograft augmentation for metaphyseal defects; 165 patients with 173 implants (71.2% did not, and served as controls. The mean follow-up was 4.4 ± 1.8 years (range, 2.1–9.6 years. There were no significant differences (p > 0.05 between the study and control group regarding age, body mass index (BMI, femoral defects (types I-III as described by Paprosky, and preoperative Harris Hip Score (HHS. Postoperative clinical function was evaluated using the HHS. Postoperative radiologic examination evaluated implant stability, axial implant migration, signs of implant loosening, periprosthetic radiolucencies, as well as bone regeneration and resorption. Results There were comparable rates of intraoperative and postoperative complications in the study and control groups (p > 0.05. Clinical function, expressed as the increase in the postoperative HHS over the preoperative score, showed significantly greater improvement in the group with Impaction Bone Grafting (35.6 ± 14.3 vs. 30.8 ± 15.8; p ≤ 0.05. The study group showed better outcome especially for larger defects (types II C and III as described by Paprosky and stem diameters ≥ 17 mm. The two groups did not show significant differences in the rate of aseptic loosening (1.4% vs. 2.9% and the rate of revisions (8.6% vs. 11%.

    2012-01-01

    Full Text Available Introduction. White Sponge Nevus (WSN is a rare pathology with a pathogenesis on genetic basis, a benign course and a localization affecting the mucosal keratin.WSN is usually a symptomless pathology: when pain is present, some authors reported reduction of symptoms by taking penicillin or oral tetracycline rinses, suggesting that a bacterial overinfection could be at the base of possible painful symptoms.Case Report. We describe 2 patients affected by WSN, father and son: they presented two different oral diseases associated with an infection by Staphylococcus aureus. So, we have performed a careful oral hygiene to reduce infection in the oral cavity. In the following days we prescribed 2 rinses a day with a mouthwash containing chlorhexidine digluconate at two different percentages.Discussion. Early diagnosis of this lesion is important, because it allows us to exclude other more serious diseases. In the most part of cases, WSN requires no treatment because of its benign and asymptomatic behaviour: up to now, no protocol of treatment for this condition was standardized. Even if WSN is a painless condition, sometime a correlated painful symptomatology was reported.Conclusions. In our experience, we have achieved excellent results even with chlorhexidine digluconate rinses, considering that our treated cases were both infected by Staphylococcus aureus.We hypothesize that the corrugated plaques and the altered texture of the mucosa create the right conditions for the colonization and the development of microbial species such as saprophytic bacteria or fungal species.

  13. Olkiluoto site description 2004

    International Nuclear Information System (INIS)

    This Olkiluoto Site Description 2004 is a description of the Olkiluoto site, in which the various disciplines have been integrated to produce a coherent picture, and is based on the data available prior to the start of the underground excavation of the ONKALO facility. This report is the first version of such a Site Report and supplements the site syntheses that have already been published. Further Site Reports will be produced on a regular basis and it is planned that the Site Report should form the geoscientific basis of the Safety Case in a future licence application. The report updates the Baseline report published in 2003 and is designed to produce an integrated site model, by focusing on interdisciplinary interactions, and also by including new data obtained during 2003 and 2004. The report has been produced by the OMTF (Olkiluoto Modelling Task Force), which covers the areas of geology, rock mechanics, hydrogeology and hydrogeochemistry. In addition to discussing the input from these four disciplines, the Site Report also includes a description of the surface conditions. Formally, the surface conditions are not within the remit of the OMTF, which is concentrating on modelling the bedrock around the ONKALO and the future repository. The influence of the surface conditions to the overall system and to the conditions at depth is recognised, however, and thus a summary of climate, ecosystems and overburden properties is also included in this report. Chapter 1 sets out the methodology to be used in the modelling, describes the various discipline-specific models which are developed and the modelled areas which are used, and also describes two important processes - the prediction/outcome studies and the uncertainty and confidence assessment. The difference between the estimate (the prediction) and the result (the outcome) indicates the level of knowledge and the prevailing uncertainties in the models. Chapter 2 presents the applied investigation data, which are

    Full Text Available Abstract Background In Switzerland there are about 150,000 equestrians. Horse related injuries, including head and spinal injuries, are frequently treated at our level I trauma centre. Objectives To analyse injury patterns, protective factors, and risk factors related to horse riding, and to define groups of safer riders and those at greater risk Methods We present a retrospective and a case-control survey at conducted a tertiary trauma centre in Bern, Switzerland. Injured equestrians from July 2000 - June 2006 were retrospectively classified by injury pattern and neurological symptoms. Injured equestrians from July-December 2008 were prospectively collected using a questionnaire with 17 variables. The same questionnaire was applied in non-injured controls. Multiple logistic regression was performed, and combined risk factors were calculated using inference trees. Results Retrospective survey A total of 528 injuries occured in 365 patients. The injury pattern revealed as follows: extremities (32%: upper 17%, lower 15%, head (24%, spine (14%, thorax (9%, face (9%, pelvis (7% and abdomen (2%. Two injuries were fatal. One case resulted in quadriplegia, one in paraplegia. Case-control survey 61 patients and 102 controls (patients: 72% female, 28% male; controls: 63% female, 37% male were included. Falls were most frequent (65%, followed by horse kicks (19% and horse bites (2%. Variables statistically significant for the controls were: Older age (p = 0.015, male gender (p = 0.04 and holding a diploma in horse riding (p = 0.004. Inference trees revealed typical groups less and more likely to suffer injury. Conclusions Experience with riding and having passed a diploma in horse riding seem to be protective factors. Educational levels and injury risk should be graded within an educational level-injury risk index.

    Afemale patient with recurrent posterior reversible encephalopathy syndrome, severe hypocalcemia due to extirpation of the parathyroid glands is described. The disease was characterized by the acute development of headache, seizures, cognitive and behavioral disorders, mental confusion, transitory blood pressure increasing. The vasogenic edema in the posterior parts of the brain, detected by CT at the first exacerbation,was completely regressed. The residual neurological deficit and MRI changes remained after the recurrent exacerbations. Main clinical features of PRESare explained by hypocalcemia and accompanying electrolyte disturbances.The reported case shows the necessity to study blood electrolytes in patients with PRES to clarify their pathogenic role and the necessity of drug correction.

    Full Text Available Eosinophilic meningoencephalitis (EME has been described in various species of animals and in humans. In dogs it has been associated with protozoal infections, cuterebral myiasis and various other aetiologies. Ten cases of idiopathic eosinophilic meningoencephalitis have been reported in dogs and one in a cat where the origin was uncertain or unknown. The dogs were all males, of various breeds but with a predominance of Golden Retrievers and Rottweilers; they generally had a young age of onset. Two cases with no apparent underlying aetiology were diagnosed on post mortem examination. The 18-month-old, male Boerboel presented with sudden onset of cerebellar ataxia, as well as various asymmetrical cranial nerve deficits of 2 weeks' duration and without progression. Haematology revealed a peripheral eosinophilia. Necropsy showed extreme generalised congestion especially of the meninges and blood smear and histological sections of various tissues showed intravascular erythrocyte fragmentation with the formation of microcytes. Histopathology revealed severe diffuse cerebrocortical subarachnoidal meningitis and submeningeal encephalitis, the exudate containing variable numbers of eosinophils together with neutrophils and mononuclear cells. There was also deeper white matter and hippocampal multifocal perivascular mononuclear encephalitis and multifocal periventricular malacia, gliosis and phagocytosis of white matter. The cerebellum, brain stem and spinal cord showed only mild multifocal oedema or scattered occasional axon and myelin degeneration respectively, with no inflammation. Immunohistochemical staining of central nervous tissue for Toxoplasma gondii failed to show any antigen in the central nervous tissue. Ultrastructure of a single submeningeal suspected parasitic cyst showed it to be chromatin clumping within a neuron nucleus indicating karyorrhexis. Gram stain provided no evidence of an aetiological agent. The 3-year-old Beagle bitch had a

    Full Text Available Low vitamin D levels have been described in obese individuals and in some autoimmune diseases, such as Systemic Lupus Erythematosus (SLE and primary antiphospholipid syndrome (pAPS. In particular, more than 50% of premenopausal women with pAPS have hypovitaminosis D. In this issue we report a case of an obese, premenopausal, and hypertensive woman with pseudo-Cushing syndrome, affected by deep venous thrombosis associated with pulmonary embolism after rib fracture who presented hypovitaminosis D. 7 years before, diagnosis of pAPS had been made after the detection of thrombocytopenia (present at a young age and arterial ischemia of a lower limb. For seven years she was treated with acetylsalicylic acid without complications. We found positive anti-dsDNA antibodies, a triple antiphospholipid antibodies (aPL positivity and levels of vitamin D < 4 µg/l. The case report arises some questions: is vitamin D deficiency due to obesity or APS? Is the positivity of anti-dsDNA indicative of progression to SLE? Is preventive therapy with hydroxychloroquine indicated? Does the high-risk aPL profile justify a high-intensity and life-long anticoagulation regimen?http://dx.doi.org/10.7175/cmi.v8i2.912

    Persistent trigeminal artery (PTA) is the most frequent embryonic communication between the carotid and vertebrobasilar systems. However, hormonal changes or the association of PTA with other sellar lesions, such as pituitary adenomas, are extremely rare. The aim of the present study was to report two patients with intrasellar PTA and simultaneous pituitary adenoma in order to emphasize the importance of differential diagnoses for sellar lesions. Case 1. A female patient, 41 years old, was admitted with a history of chronic headache (> 20 years). Pituitary magnetic resonance imaging (MRI) showed a rounded lesion in the left portion of the pituitary gland suggestive of adenoma (most likely clinically non-functioning adenoma). In addition to this lesion, the MRI demonstrated ecstasy of the right internal carotid artery and imaging suggestive of an intrasellar artery that was subsequently confirmed by an angio-MRI of the cerebral vessels as PTA. Case 2. A female patient, 42 years old, was admitted with a history of amenorrhea and galactorrhea in 1994. Laboratorial investigation revealed hyperprolactinemia. Pituitary MRI showed a small hyposignal area in the anterior portion of pituitary gland suggestive of a microadenoma initiated by a dopaminergic agonist. Upon follow-up, aside from the first lesion, the MRI showed a well delineated rounded lesion inside the pituitary gland, similar to a vessel. Angio-MRI confirmed a left primitive PTA. Failure to recognize these anomalous vessels within the sella might lead to serious complications during transsphenoidal surgery. Therefore, although their occurrence is uncommon, a working knowledge of vascular lesions in the sella turcica or pituitary gland is important for the differential diagnosis of pituitary lesions, especially pituitary adenomas.

    The purpose of this study is to describe a new algorithm based on a neural network approach (Passive microwave Neural network Precipitation Retrieval - PNPR) for precipitation rate estimation from AMSU/MHS observations, and to provide examples of its performance for specific case studies over the European/Mediterranean area. The algorithm optimally exploits the different characteristics of Advanced Microwave Sounding Unit-A (AMSU-A) and the Microwave Humidity Sounder (MHS) channels, and their combinations, including the brightness temperature (TB) differences of the 183.31 channels, with the goal of having a single neural network for different types of background surfaces (vegetated land, snow-covered surface, coast and ocean). The training of the neural network is based on the use of a cloud-radiation database, built from cloud-resolving model simulations coupled to a radiative transfer model, representative of the European and Mediterranean Basin precipitation climatology. The algorithm provides also the phase of the precipitation and a pixel-based confidence index for the evaluation of the reliability of the retrieval. Applied to different weather conditions in Europe, the algorithm shows good performance both in the identification of precipitation areas and in the retrieval of precipitation, which is particularly valuable over the extremely variable environmental and meteorological conditions of the region. The PNPR is particularly efficient in (1) screening and retrieval of precipitation over different background surfaces; (2) identification and retrieval of heavy rain for convective events; and (3) identification of precipitation over a cold/iced background, with increased uncertainties affecting light precipitation. In this paper, examples of good agreement of precipitation pattern and intensity with ground-based data (radar and rain gauges) are provided for four different case studies.

    The widespread use of Array Comparative Genomic Hybridization (aCGH) technology has enabled the identification of several syndromes associated with copy number variants (CNVs) including the 17q21.31 microdeletion. The 17q21.31 microdeletion syndrome, also known as Koolen-de Vries syndrome, was first described in 2006 in individuals with intellectual disabilities and organ abnormalities. We report the clinical, instrumental, cytogenetic and molecular investigations of a boy admitted for epilepsy and intellectual disabilities. We carried out detailed analysis of the clinical phenotype of this patient and investigated the genetic basis by using aCGH. We identified a de novo microdeletion on chromosome 17q21.31, compatible with Koolen-de Vries syndrome. Our case shares some of the typical characteristics of the syndrome already described by other authors: delayed psychomotor development, primarily affecting the expressive language, dysmorphic facial features, and epilepsy. However the clinical outcome was not severe as the intellectual disabilities were moderate with good adaptive and functional behaviour. Epilepsy was easily controlled by a single drug, and he never needed surgery for organ abnormalities.

    Full Text Available The use of the oncological principle – en bloc ablastic tumor resection – can expect a breakthrough in the treatment of baseline unfavorable patient groups. In the described case of atypical meningioma, its en bloc resection presents significant technical difficulties when accomplishing the task associated with the giant sizes of a tumor as an iceberg growing outside and into the cranial cavity, its rich vascularization from both the internal and external carotid artery system, with the involvement of the superior sagittal sinus, the presence of a dense bone crown that combines the three-component construction of a neoplasm, which made difficult safe mobilization and scanning in the cranial cavity.In such topographic variants, the criteria for the Simpson radical meningioma resection are inapplicable and only en bloc tumor resection may reflect the oncological principles of surgery. The technologies of en bloc resection of intracranial meningiomas should be more frequently used because preoperative neurovisualization and even histological diagnosis does not always allow the grade of meningiomas to be specified.

    The widespread use of Array Comparative Genomic Hybridization (aCGH) technology has enabled the identification of several syndromes associated with copy number variants (CNVs) including the 17q21.31 microdeletion. The 17q21.31 microdeletion syndrome, also known as Koolen-de Vries syndrome, was first described in 2006 in individuals with intellectual disabilities and organ abnormalities. We report the clinical, instrumental, cytogenetic and molecular investigations of a boy admitted for epilepsy and intellectual disabilities. We carried out detailed analysis of the clinical phenotype of this patient and investigated the genetic basis by using aCGH. We identified a de novo microdeletion on chromosome 17q21.31, compatible with Koolen-de Vries syndrome. Our case shares some of the typical characteristics of the syndrome already described by other authors: delayed psychomotor development, primarily affecting the expressive language, dysmorphic facial features, and epilepsy. However the clinical outcome was not severe as the intellectual disabilities were moderate with good adaptive and functional behaviour. Epilepsy was easily controlled by a single drug, and he never needed surgery for organ abnormalities. PMID:26897099

    Full Text Available Metabolic syndrome (MS is extremely common (20%–25% of the world’s population, and its diagnostic criteria are defined and well known. It has been shown that patients who have MS are twice as likely to die from a cardiovascular complication and three times as likely to suffer from it compared with patients without MS. However, the underlying cause of MS remains to be clearly elucidated, although inherited factors, such as insulin resistance (IR, and external factors are considered to play a key role in this process. Special attention should be paid to MS in young patients, who may present the first manifestation of inherited lipodystrophy. The study describes the first known family in Russia (three clinical cases with familial partial lipodystrophy (FPLD type 3 caused by heterozygous p.R212Q PPARG mutation (MIM#601487. The study reports rare forms of inherited IR, such as FPLD, and contributes to a better understanding of common disorders such as MS.

  11. Application of the Price-Volume Approach in Cases of Innovative Drugs Where Value-Based Pricing is Inadequate: Description of Real Experiences in Italy.

    Messori, Andrea

    2016-08-01

    Several cases of expensive drugs designed for large patient populations (e.g. sofosbuvir) have raised a complex question in terms of drug pricing. Even assuming value-based pricing, the treatment with these drugs of all eligible patients would have an immense budgetary impact, which is unsustainable also for the richest countries. This raises the need to reduce the prices of these agents in comparison with those suggested by the value-based approach and to devise new pricing methods that can achieve this goal. The present study discusses in detail the following two methods: (i) The approach based on setting nation-wide budget thresholds for individual innovative agents in which a fixed proportion of the historical pharmaceutical expenditure represents the maximum budget attributable to an innovative treatment; (ii) The approach based on nation-wide price-volume agreements in which drug prices are progressively reduced as more patients receive the treatment. The first approach has been developed in the USA by the Institute for Clinical and Economic Review and has been applied to PCSK9 inhibitors (alirocumab and evolocumab). The second approach has been designed for the Italian market and has found a systematic application to manage the price of ranibizumab, sofosbuvir, and PCSK9 inhibitors. While, in the past, price-volume agreements have been applied only on an empirical basis (i.e. in the absence of any quantitative theoretical rule), more recently some explicit mathematical models have been described. The performance of these models is now being evaluated on the basis of the real-world experiences conducted in some European countries, especially Italy. PMID:27216427

    Full Text Available La hernia de Amyand constituye un raro tipo de herniación inguinal en la que su contenido es el apéndice vermiforme, siendo infrecuente encontrarnos con un apéndice inflamado en el interior del saco herniario, y excepcional realizar su diagnóstico preoperatorio, siendo pocos los casos descritos en la literatura. La forma de presentación más frecuente es como una hernia inguinal incarcerada. La sospecha clínica, junto con la realización de pruebas de imagen, fundamentalmente la tomografía computarizada, permitirán una aproximación diagnóstica. El tratamiento depende de los hallazgos intraoperatorios, realizándose apendicectomía transherniotomía o laparotómica, con herniorrafia o hernioplastia inguinales, dependiendo de la presencia de inflamación apendicular o sepsis abdominal. Presentamos el caso de un paciente con una hernia de Amyand diagnosticada preoperatoriamente, con apéndice inflamado y retrocecal, sin evidencias de herniación a la exploración, al que se practicó apendicectomía por vía laparotómica con reparación herniaria en un segundo tiempo.Amyand's hernia is a rare form of inguinal hernia in which the content is the appendix. It is rare to find an inflamed appendix in the inguinal hernia sac and exceptional to perform a presurgical diagnosis, the number of cases described in the literature being small. The most frequent presentation form is as an incarcerated inguinal hernia. The diagnostic approach is based on the clinical suspicion together with imagery techniques, basically computerized tomography. The treatment depends on the intrasurgical findings, either appendix inflammation or abdominal sepsis indicating transherniotomy or laparotomic appendectomy, with inguinal herniorrhaphy or hernioplasty. We present one patient with an Amyand's hernia diagnosed prior to the surgery, with an inflamed retrocecal appendix, without evidence of hernia on clinical examination.

    1994-01-01

    Hardware description languages are special purpose programming languages. They are primarily used to specify the behavior of digital systems and are rapidly replacing traditional digital system design techniques. This is because they allow the designer to concentrate on how the system should operate rather than on implementation details. Hardware description languages allow a digital system to be described with a wide range of abstraction, and they support top down design techniques. A key feature of any hardware description language environment is its ability to simulate the modeled system. The two most important hardware description languages are Verilog and VHDL. Verilog has been the dominant language for the design of application specific integrated circuits (ASIC's). However, VHDL is rapidly gaining in popularity.

    Full Text Available Misophonia is a relatively unexplored chronic condition in which a person experiences autonomic arousal (analogous to an involuntary fight-or-flight response to certain innocuous or repetitive sounds such as chewing, pen clicking and lip smacking. Misophonics report anxiety, panic and rage when exposed to trigger sounds, compromising their ability to complete everyday tasks and engage in healthy and normal social interactions. Across two experiments, we measured behavioral and physiological characteristics of the condition. Interviews (Experiment 1 with misophonics showed that the most problematic sounds are generally related to other people's behavior (pen clicking, chewing sounds. Misophonics are however not bothered when they produce these trigger sounds themselves, and some report mimicry as a coping strategy. Next, (Experiment 2 we tested the hypothesis that misophonics’ subjective experiences evoke an anomalous physiological response to certain auditory stimuli. Misophonic individuals showed heightened ratings and skin conductance responses to auditory, but not visual stimuli, relative to a group of typically developed controls, supporting this general viewpoint and indicating that misophonia is a disorder that produces distinct autonomic effects not seen in typically developed individuals.

  1. Career Path Descriptions

    CERN Document Server

    Charkiewicz, A

    2000-01-01

    Before the Career Path system, jobs were classified according to grades with general statutory definitions, guided by the "Job Catalogue" which defined 6 evaluation criteria with example illustrations in the form of "typical" job descriptions. Career Paths were given concise statutory definitions necessitating a method of description and evaluation adapted to their new wider-band salary concept. Evaluations were derived from the same 6 criteria but the typical descriptions became unusable. In 1999, a sub-group of the Standing Concertation Committee proposed a new guide for describing Career Paths, adapted to their wider career concept by expanding the 6 evaluation criteria into 9. For each criterion several levels were established tracing the expected evolution of job level profiles and personal competencies over their longer salary ranges. While providing more transparency to supervisors and staff, the Guide's official use would be by services responsible for vacancy notices, Career Path evaluations and rela...

    2006-11-01

    Full Text Available The literature is not kind to the use of descriptive generalizations. Authors struggle and struggle to find and rationalize a way to use them and then fail in spite of trying a myriad of work-arounds. And then we have Lincoln and Guba’s famous statement: “The only generalization is: there is no generalization” in referring to qualitative research. (op cit, p. 110 They are referring to routine QDA yielding extensive descriptions, but which tacitly include conceptual generalizations without any real thought of knowledge about them. In this chapter I wish to explore this struggle for the purpose of explaining that the various contra arguments to using descriptive generalizations DO NOT apply to the ease of using conceptual generalizations yielded in SGT and especially FGT. I will not argue for the use of descriptive generalization. I agree with Lincoln and Guba with respect to QDA, “the only generalization is: there is no generalization.” It is up to the QDA methodologists, of whom there are many; to continue the struggle and I wish them well.

    Quantification of categorical, or non-numerical, data is a problem that scientists face across a wide range of disciplines. Exploring data analysis in various areas of research, such as the social sciences and biology, Multidimensional Nonlinear Descriptive Analysis presents methods for analyzing categorical data that are not necessarily sampled randomly from a normal population and often involve nonlinear relations. This reference not only provides an overview of multidimensional nonlinear descriptive analysis (MUNDA) of discrete data, it also offers new results in a variety of fields. The first part of the book covers conceptual and technical preliminaries needed to understand the data analysis in subsequent chapters. The next two parts contain applications of MUNDA to diverse data types, with each chapter devoted to one type of categorical data, a brief historical comment, and basic skills peculiar to the data types. The final part examines several problems and then concludes with suggestions for futu...

    Allamigeon, Xavier; Goubault, Eric

    2010-01-01

    We develop a tropical analogue of the classical double description method allowing one to compute an internal representation (in terms of vertices) of a polyhedron defined externally (by inequalities). The heart of the tropical algorithm is a characterization of the extreme points of a polyhedron in terms of a system of constraints which define it. We show that checking the extremality of a point reduces to checking whether there is only one minimal strongly connected component in an hypergraph. The latter problem can be solved in almost linear time, which allows us to eliminate quickly redundant generators. We report extensive tests (including benchmarks from an application to static analysis) showing that the method outperforms experimentally the previous ones by orders of magnitude. The present tools also lead to worst case bounds which improve the ones provided by previous methods.

    CERN Document Server

    Straccia, U

    2011-01-01

    Description Logics (DLs) are suitable, well-known, logics for managing structured knowledge. They allow reasoning about individuals and well defined concepts, i.e., set of individuals with common properties. The experience in using DLs in applications has shown that in many cases we would like to extend their capabilities. In particular, their use in the context of Multimedia Information Retrieval (MIR) leads to the convincement that such DLs should allow the treatment of the inherent imprecision in multimedia object content representation and retrieval. In this paper we will present a fuzzy extension of ALC, combining Zadeh's fuzzy logic with a classical DL. In particular, concepts becomes fuzzy and, thus, reasoning about imprecise concepts is supported. We will define its syntax, its semantics, describe its properties and present a constraint propagation calculus for reasoning in it.

The W3C standard OWL defines one of the most important ontology languages based on the semantics of description logics. An alternative is to use rule languages in knowledge modelling, as proposed in the W3C's RIF standard. So far, it has often been unclear how to combine both technologies without sacrificing essential computational properties. This book explains this problem and presents new solutions that have recently been proposed. Extensive introductory chapters provide the necessary

    2014-11-01

    The article presents a proposal for the description of human gait as a periodic and symmetric process. Firstly, the data for researches was obtained in the Laboratory of Group SATI in the School of Engineering of University of Valencia. Then, the periodical model - Mean Double Step (MDS) was made. Finally, on the basis of MDS, the symmetrical models - Left Mean Double Step and Right Mean Double Step (LMDS and RMDS) could be created. The method of various functional extensions was used. Symmetrical gait models can be used to calculate the coefficients of asymmetry at any time or phase of the gait. In this way it is possible to create asymmetry, function which better describes human gait dysfunction. The paper also describes an algorithm for calculating symmetric models, and shows exemplary results based on the experimental data.

    2005-01-01

    Task Description Language (TDL) is an extension of the C++ programming language that enables programmers to quickly and easily write complex, concurrent computer programs for controlling real-time autonomous systems, including robots and spacecraft. TDL is based on earlier work (circa 1984 through 1989) on the Task Control Architecture (TCA). TDL provides syntactic support for hierarchical task-level control functions, including task decomposition, synchronization, execution monitoring, and exception handling. A Java-language-based compiler transforms TDL programs into pure C++ code that includes calls to a platform-independent task-control-management (TCM) library. TDL has been used to control and coordinate multiple heterogeneous robots in projects sponsored by NASA and the Defense Advanced Research Projects Agency (DARPA). It has also been used in Brazil to control an autonomous airship and in Canada to control a robotic manipulator.

  3. Description of Jet Breakup

    1996-01-01

    In this article we review recent results on the breakup of cylindrical jets of a Newtonian fluid. Capillary forces provide the main driving mechanism and our interest is in the description of the flow as the jet pinches to form drops. The approach is to describe such topological singularities by constructing local (in time and space) similarity solutions from the governing equations. This is described for breakup according to the Euler, Stokes or Navier-Stokes equations. It is found that slender jet theories can be applied when viscosity is present, but for inviscid jets the local shape of the jet at breakup is most likely of a non-slender geometry. Systems of one-dimensional models of the governing equations are solved numerically in order to illustrate these differences.

    Ben-Menahem, Yemima

    This paper deals with the dependence of directionality in the course of events-or our claims concerning such directionality-on the modes of description we use in speaking of the events in question. I argue that criteria of similarity and individuation play a crucial role in assessments of directionality. This is an extension of Davidson's claim regarding the difference between causal and explanatory contexts. The argument is based on a characterisation of notions of necessity and contingency that differ from their modal logic counterparts on the one hand, and from causality and chance on the other. I show that some types of directionality are perfectly compatible with both determinism and indeterminism at the microscopic level, and that there is no likelihood of, or advantage to, reducing such directionality to other laws or causal processes.

  6. YUCCA MOUNTAIN SITE DESCRIPTION

    2004-04-16

    The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel.

    The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel

The adequacy of FDTs, namely SDL, for the manufacturing systems domain is investigated by developing the ...

  10. [Descriptive epidemiology of urolithiasis].

    Science.gov (United States)

    Kodama, H; Ohno, Y

    1989-06-01

    In this paper, urolithiasis is remarked from the standpoint of descriptive epidemiology, which examines the frequency distribution of a given disease in a population in terms of time, place and personal characteristics with an aim of identifying risk factors or some clues to the etiology. Some descriptive epidemiological features of urolithiasis are summarized. Prevalence rate is around 4% (4-15% in males and 4-8% in females), and incidence rate varies from area to area: 53.2 per 100,000 population in 1975 in Japan, 364 in 1976 in Malaysia, and 540 in 1979 in West Germany. Prevalence and/or incidence rates have, in general, increased in the developed countries since World War II and in the developing countries as well, where upward trends are quite analogous to the trends observed in the nineteenth century in Europe. Recurrence rate, which is much higher in males than in females, ranges from 31% to 75%, depending on the follow-up periods. In the industrialized countries, upper urinary (renal and ureteral) stones account for more than 90% of total stones, which are ordinarily calcium complexes in composition. More common in the developing countries are lower urinary (bladder and urethral) stones, frequently composed of magnesium ammonium phosphate, which indicates a close association with urinary tract infections. Variations in frequency are evident by season and by region within a country. Age and sex differentials in urinary stone formers are substantial: more common in males 30-40 years old in the industrialized countries and in children under 10 years old in the developing countries. Racial differentials are also noted; blacks appear to suffer less frequently than whites. Stone formers experience more frequent episodes of stone formation in their family members, particularly father and brothers, than non-stone formers. These findings on racial differentials and family preponderance suggest the possible relevance of genetic factors in stone formation. Stone

  15. Field theory description of neutrino oscillations

    CERN Document Server

    Dvornikov, Maxim

    2010-01-01

    We review various field theory approaches to the description of neutrino oscillations in vacuum and external fields. First we discuss a relativistic quantum mechanics based approach which involves the temporal evolution of massive neutrinos. To describe the dynamics of the neutrinos system we use exact solutions of wave equations in presence of an external field. It allows one to exactly take into account both the characteristics of neutrinos and the properties of an external field. In particular, we examine flavor oscillations an vacuum and in background matter as well as spin flavor oscillations in matter under the influence of an external electromagnetic field. Moreover we consider the situation of hypothetical nonstandard neutrino interactions with background fermions. In the case of ultrarelativistic particles we reproduce an effective Hamiltonian which is used in the standard quantum mechanical approach for the description of neutrino oscillations. The corrections to the quantum mechanical Hamiltonian a...

  16. Fluid description for the resonant Weibel instability

    CERN Document Server

    Sarrat, M; Ghizzo, A

    2016-01-01

    We discuss a fluid model with inclusion of the complete pressure tensor dynamics for the description of Weibel type instabilities in a counterstreaming beams configuration. Differently from the case recently studied in Sarrat et al. 2016, where perturbations perpendicular to the beams were considered, here we focus only on modes propagating along the beams. Such a configuration is responsible for the growth of two kind of instabilities, the Two-Stream Instability and the Weibel instability, which in this geometry becomes "time-resonant", i.e. propagative. This fluid description agrees with the kinetic one and makes it possible e.g. to identify the transition between non-propagative and propagative Weibel modes, already evidenced by Lazar et al. 2009 as a "slope-breaking" of the growth rate, in terms of a merger of two non propagative Weibel modes.

    ZHANG Xin; PAN Feng

    2004-01-01

    U(3)-O(4) transitional description of diatomic molecules in the U(4) vibron model is studied by using the algebraic Bethe ansatz, in which the O(4) limit is a special case of the theory. Vibrational band-heads of some typical diatornic molecules are fitted by both transitional theory and the O(4) limit within the same framework. The results show that there are evident deviations from the O(4) limit in description of vibrational spectra of some diatomic molecules.

  19. The Fundamental Scale of Descriptions

    CERN Document Server

    Febres, Gerardo

    2014-01-01

    The complexity of a system description is a function of the entropy of its symbolic description. Prior to computing the entropy of the system description, an observation scale has to be assumed. In natural language texts, typical scales are binary, characters, and words. However, considering languages as structures built around certain preconceived set of symbols, like words or characters, is only a presumption. This study depicts the notion of the Description Fundamental Scale as a set of symbols which serves to analyze the essence a language structure. The concept of Fundamental Scale is tested using English and MIDI music texts by means of an algorithm developed to search for a set of symbols, which minimizes the system observed entropy, and therefore best expresses the fundamental scale of the language employed. Test results show that it is possible to find the Fundamental Scale of some languages. The concept of Fundamental Scale, and the method for its determination, emerges as an interesting tool to fac...

  2. On the thermodynamic description of real systems

    International Nuclear Information System (INIS)

    A new method of approach to the theory of the thermodynamic properties of real systems is proposed, to include interactions among the constituent particles of the system. The method consists in obtaining the entropy of a real system from the entropy of the corresponding ideal system by a translation in the internal energy and other relevant extensive variables. The usefulness of the method is displayed by application to the cases of: (i) real gases, and (ii) spin paramagnetism with interactions among spins. It is shown that this description corresponds to a generalization of the molecular field approximation. (Author)

    Under the framework of non-equilibrium thermodynamic separation theory (NTST), Local Lagrangian approach (LLA) was proposed to deal with the essential issues of the convection and diffusion (shock waves) phenomena in nonlinear chromatography with recursion equations based on the three basic theorems, Lagrangian description, continuity axiom and local equilibrium assumption (LEA). This approach remarkably distinguished from the system of contemporary chromatographic theories (Eulerian description-partial differential equations), and can felicitously match modern cybernetics.

  6. Reading Words and Images in the Description(s of Sir John Soane’s Museum

    2016-05-01

    Full Text Available In the 18th and early 19th centuries, London was a city filled with cabinets of curiosity, 'lusus naturae', and bourgeoning public museums. Most of these institutions publicized their holdings through newspaper advertisements, leaflets, and self-published, descriptive catalogs that were available for purchase on-site and through booksellers. Using Soane’s Museum as a case study, this paper will move beyond historiographical analysis of individual objects in collections catalogs to probe how the museum-produced guidebooks depicted spatial arrangements. Citing examples from the 19th to twenty-first centuries, this paper will examine how the curator-produced descriptions of Soane’s Museum manipulated text and graphics to guide visitors through a constructed narrative, recreated the ephemeral experiences of the museum, and advertise the site’s unparalleled union of painting, sculpture, and architecture to audiences abroad. Soane’s 'Description of the House and Museum, on the North Side of Lincoln‘s Inn-Fields, the Residence of Sir John Soane' (privately printed 1830, 1832; revised 1835 paired spatial narratives with the architectural language of orthographic projection and perspective engravings. His 'Description' set forth an agenda about the museum’s arrangement and established a compositional strategy for subsequent editions of the guidebook, renamed the 'General Description' in the editions printed between 1840 and 1930 then rebranded as the 'New Description' by Summerson in 1955. Through the study of the changing written and visual language published in the guides by the curators of Soane’s Museum, this article will examine the changing character of the visitor experience at the museum and question the form of future editions.

    2014-01-01

    Readers who are familiar with Haruki Murakami know that the writer admires many American writers, Fitzgerald in particular. What’s worth noting is that the two writers have something in common in their way of describing urban areas. From the early novelPinball, 1973toColorlessTsukuruTazakiandHisYearsofPilgrimage, the description of urban areas appears throughout Murakami’s works. However, in the transitional period of his creation, in addition to the individual themes in urban novels, Murakami began to involve social issues in his writing, like Sarin gas attack on the subway, war and high capitalism. His works in this period accordingly show this change. Focusing onDanceDanceDance, the paper is searching for the change in his urban description.%熟悉村上春树的读者们都知道,村上喜爱很多美国作家,其中菲茨杰拉德可说是他第一推崇。其中尤其值得注意的是“城市表述”上的关连。从初期的《1973年的弹子球》到最近推出的《没有色彩的多崎作和他的巡礼之年》,“都市表述”贯穿了每个时期的小说创作。然而在其过渡期的作品中,村上春树跳脱“都市小说”以个人为主题的形式,融入“地铁沙林事件”、战争、高度资本主义等社会议题,这些小说更是突出了村上其创作开拓的领域。因此本文聚焦《舞舞舞》,寻访在“过渡期”阶段村上文学中“城市表述”的转变。

    Periprosthetic osteolysis is a well known phenomenon caused by wear particle-induced bone resorption, particularly common and extensively reported in total hip arthroplasty. Its typical radiographic feature is a radiolucent area adjacent to an implant, sometimes associated with a soft tissue mass. Osteolytic changes may be caused by numerous other pathologic processes, including infection, metabolic disease, and neoplasia. Four cases of massive periprosthetic bone destruction associated with a large soft tissue mass around a failed total hip replacement are presented. In three cases, a diagnosis of periprosthetic osteolysis was correctly made and managed by revision surgery. However, in one case angiosarcoma of the ipsilateral hemipelvis went long unrecognized despite aggressive clinical course, requiring hind-quarter amputation and ultimately resulting in the patient's death. Periprosthetic malignancy in the form of either primary sarcoma or metastatic cancer is a very rare yet reported event in the setting of previous hip replacement, likely leading to catastrophic consequences when diagnosis is not established in a timely manner. The differential diagnosis of periprosthetic osteolysis should consider the entire spectrum of conditions that can present with radiolucent changes. Thorough review of patient's history and course of symptoms, along with careful evaluation of standard roentgenograms should be always performed and possibly integrated with imaging modalities such as CT, MRI, and bone scintigraphy in order to increase diagnostic accuracy. If uncertainty remains, biopsy should always be considered to rule out malignancy.

    Full Text Available Abstract Background A number of single case reports have suggested that the context within which intervention studies take place may challenge the assumptions that underpin randomised controlled trials (RCTs. However, the diverse ways in which context may challenge the central tenets of the RCT, and the degree to which this information is known to researchers or subsequently reported, has received much less attention. In this paper, we explore these issues by focusing on seven RCTs of interventions varying in type and degree of complexity, and across diverse contexts. Methods This in-depth multiple case study using interviews, focus groups and documentary analysis was conducted in two phases. In phase one, a RCT of a nurse-led intervention provided a single exploratory case and informed the design, sampling and data collection within the main study. Phase two consisted of a multiple explanatory case study covering a spectrum of trials of different types of complex intervention. A total of eighty-four data sources across the seven trials were accessed. Results We present consistent empirical evidence across all trials to indicate that four key elements of context (personal, organisational, trial and problem context are crucial to understanding how a complex intervention works and to enable both assessments of internal validity and likely generalisability to other settings. The ways in which context challenged trial operation was often complex, idiosyncratic, and subtle; often falling outside of current trial reporting formats. However, information on such issues appeared to be available via first hand ‘insider accounts’ of each trial suggesting that improved reporting on the role of context is possible. Conclusions Sufficient detail about context needs to be understood and reported in RCTs of complex interventions, in order for the transferability of complex interventions to be assessed.

    Full Text Available É apresentado um caso clínico de paciente portador de paralisia facial periférica com comprometimento de toda a hemiface direita. Durante a investigação clínica, esperava-se que o comprometimento topográfico do nervo facial se desse a partir de sua emergência na ponte. Após exames de imagem, evidenciou-se lesão expansiva no tronco cerebral. Deste modo, a classificação de paralisia facial como periférica ou central não atende a este caso. O uso de uma classificação utilizando os núcleos do nervo facial como referência pode ser mais adequado na investigação clínica da paralisia facial.It is presented a clinical case of a patient with a peripheral facial paralysis with hemifacial compromise. During the clinical investigation it was expected that the topographic compromise of the facial nerve would arise out of the emergence of the nerve from the pons. After some image examinations, an expansive brain trunk lesion was evidenced. Thus, the classification of facial paralysis - either peripheral or central - is not applicable to this case. The use of a classification having the facial nerve nucleus as reference could be more adequate in the clinical investigation of the paralysis.

    During 2002, SKB is starting detailed investigations at two potential sites for a deep repository in the Precambrian rocks of the Fennoscandian Shield. The present report concerns one of those sites, Simpevarp, which lies in the municipality of Oskarshamn, on the southeast coast of Sweden, about 250 kilometres south of Stockholm. The site description will have two main components: a written synthesis of the site, summarising the current state of knowledge, as documented in the databases containing the primary data from the site investigations, and one or several site descriptive models, in which the collected information is interpreted and presented in a form which can be used in numerical models for rock engineering, environmental impact and long-term safety assessments. SKB maintains two main databases at the present time, a site characterisation database called SICADA and a geographic information system called SKB GIS. The site descriptive model will be developed and presented with the aid of the SKB GIS capabilities, and with SKBs Rock Visualisation System (RVS), which is also linked to SICADA. The version 0 model forms an important framework for subsequent model versions, which are developed successively, as new information from the site investigations becomes available. Version 0 is developed out of the information available at the start of the site investigation. In the case of Simpevarp, this is essentially the information which was compiled for the Oskarshamn feasibility study, which led to the choice of that area as a favourable object for further study, together with information collected since its completion. This information, with the exception of the extensive data base from the nearby Aespoe Hard Rock Laboratory, is mainly 2D in nature (surface data), and is general and regional, rather than site-specific, in content. Against this background, the present report consists of the following components: an overview of the present content of the databases

    2016-11-01

    A general description of circularly symmetric Bessel beams of arbitrary order is derived in this paper. This is achieved by analyzing the relationship between different descriptions of polarized Bessel beams obtained using different approaches. It is shown that a class of circularly symmetric Davis Bessel beams derived using the Hertz vector potentials possesses the same general functional dependence as the aplanatic Bessel beams generated using the angular spectrum representation (ASR). This result bridges the gap between different descriptions of Bessel beams and leads to a general description of circularly symmetric Bessel beams, such that the Davis Bessel beams and the aplanatic Bessel beams are merely the two simplest cases of an infinite number of possible circularly symmetric Bessel beams. Additionally, magnitude profiles of the electric and magnetic fields, the energy density and the Poynting vector are displayed for Bessel beams in both paraxial and nonparaxial cases. The results presented in this paper provide a fresh perspective on the description of Bessel beams and cast some insights into the light scattering and light-matter interactions problems in practice.

    Full Text Available BACKGROUND Laryngeal cancer is the second most common head and neck cancer in India. The onset, rate of progression and duration of symptoms are variable for supraglottic, glottic and subglottic cancer. Smoking and alcohol are also most important risk factors for laryngeal cancer. Data regarding cases of laryngeal cancer in relation to age, sex, symptoms and signs, aetiological factors with special reference to smoking and alcohol, histopathological types, tumour staging, treatment and outcomes are important to assess changing trends in laryngeal cancer treatment. MATERIALS AND METHODS This study is about retrospective descriptive analysis of diagnosed and treated cases of laryngeal cancer in the Department of ENT from 2005 to 2008. Total fifty patients with laryngeal malignancy were seen from May 2005 to May 2008 with average 1 year of follow-up. Data regarding cases of laryngeal cancer in relation to age, sex, symptoms and signs, aetiological factors with special reference to smoking and alcohol, histopathological types, tumour staging, treatment and outcomes were analysed using SPSS software. All patients who were diagnosed to have laryngeal cancer and treated were included in the study. RESULTS In this descriptive analysis, 62% patients are between 51-70 years. Most of the patients had been symptomatic for 3-5 months; 58% patients presented with voice change followed by other complaints like throat pain, foreign body sensation, otalgia, breathing difficulty. Voice change was distinctly the most common symptom regardless of tumour site. It was more prevalent in glottis cases, but it was also the leading symptom in supraglottic tumours. Glottis tumours were more often found at an early stage and patients with a supraglottic tumour presented more often with neck node metastasis. CONCLUSION Laryngeal malignancy is one of the head and neck malignancies, which are more common in males. Tobacco is an important risk factor in causation of the

    Full Text Available Many descriptions and classifications of personality have been made to understand and acknowledge human being through out the history. During the developmental process of psychiatry, almost every school defined and assessed personality regarding to their own perspective. As DSM (Diagnostical and Statistical Manual of Mental Disorders and ICD (International Classification of Diseases being available to common usage, scientists conducted studies to set a common terminology for personality. Categorical and dimensional approaches are the most fundamentally different assessment strategies in the research and clinical aspects about personality. While categorical approach views the personality as dichotomies which consists of different groups, dimensional approach aims to describe the personality on the basis of dimensions, thus suggests that the personality is a structure formed by definite dimensions. Several advantages and disadvantages can be noticed when descriptions of personality and tools for the evaluation of personality are reviewed. When the section making suggestions about personality disorder in DSM-5 is evaluated, it is seen that it aims to restructure the personality disorder diagnostic group according to new findings and critiques. In this article, the description of personality throughout the history, dimensional, categorical and cognitive approaches to personality, the features of the tools that are used to assess and measure the personality are reviewed.

    Full Text Available Subject description of fiction in the Slovenian Cooperative On-line Bibliographic Database (COBIB is still inadequate. Participation in COBIB is granted to librarians who have successfully passed the exam. As a consequence, the number of contributing librarians is limited. However, all Slovenian librarians can collaborate in the Slovenian Wikipedia. Slovenian and foreign library science researchers have proposed the structure of subject description of fiction. An analysis of articles describing nine works of fiction in five wikipedias (English, French, Spanish, Croatian and Slovenian has shown new characteristics. Drawing on these findings, a suggestion of an optimal structure is made. An article describing a work of fiction should begin with a general introductory statement comprising the name of the author, his/her nationality and genre.Translators and original title should be written if a translation is presented. Illustrators and other contributors, the background and other specific information on the work should be added if relevant. The main body of the text should be structured in the following chapters: 1 contents, 2 collection, 3 reviews and awards, 4 editions and translations, 5 adaptations, 6 see also, 7 links and 8 sources. An "infobox: book" with Slovenian adaptation and relevant categories should be inserted. Copying these Wikipedia articles into the library catalogue would enhance subject description and provide better subject access to fiction.

    1994-09-01

    We report vertical transmission of a Goldenhar-like syndrome, including a father and 5 offspring, with male-to-male transmission and variable features that include hearing loss, ear anomalies (microtia, ear tags/pits), branchial cysts, ocular/periocular dermoids, micrognathia and seizures. We also report an individual with an apparently balanced de novo reciprocal translocation with breakpoints at 4p16 and 8q24.11. This individual has unilateral microtia, an epibulbar dermoid cyst, facial asymmetry with a small chin, and seizures. In addition to these features resembling those seen in the family above, she has multiple exostoses, supraventricular tachycardia, hypoglycemia and mild developmental delays. Based on the overlap in physical findings between this family and the individual with the de novo reciprocal translocation, linkage studies on the family were intiated. Preliminary results exclude linkage to HOX 7 at 4p16.1 but not to 8q. The brancho-oto-renal syndrome has previously been localized to 8q11-8q13, but linkage to this region appears unlikely. Although most cases of Goldenhar syndrome appear to be sporadic, there are a few reports of autosomal dominant inheritance (MIM No. 164210). One such family showed vertical transmission of dermoids, ear anomalies, hearing loss, micrognathia and vertebral anomalies, but no branchial cysts. Another family showed sensorineural deafness, preauricular pits, and branchial fistulae, and other families reveal ear anomalies, branchial fistulas, and hearing loss. These latter families appear to lack ocular/periocular dermoids, and appear to be affected by a different disorder (MIM No. 125100). Further clinical delineation of such families, combined with genetic linkage analysis, should help to sort out this heterogeneity.

    A. J. Lucendo Villarín

    2005-04-01

    Full Text Available Background: eosinophilic esophagitis is a rare condition mainly affecting children, although the number of cases reported in adults is on the increase. It is characterized by intense infiltration of eosinophilic leukocytes in the esophageal mucosa, without involvement of other sections of the alimentary canal. Material and methods: over the past year, following the performance of endoscopies and biopsies, our service identified nine patients who were diagnosed with suffering from this disorder. Each patient sought medical help for episodes of long-term, self-limited dysphagia or food impaction in the alimentary canal. Results: endoscopy revealed esophageal stenosis in the form of simultaneous contraction rings or regular stenosis. In six cases, the manometric study showed a nonspecific motor disorder of severe intensity affecting the esophageal body, and another patient had a disorder characterized by the presence of simultaneous waves and secondary peristaltic waves in the three thirds of the organ. These disorders are presumably due to eosinophilic infiltration of the muscular layer or ganglionar cells of the esophagus, and account for symptoms in these patients. Although the etiopathogenesis of this illness is uncertain, it is clearly an immunoallergic manifestation. Conclusions: as the number of diagnosed cases is on the increase, eosinophilic esophagitis is in adults a specific entity within the differential diagnosis of dysphagia in young males with a history of allergies. Eosiniphilic esophagitis responds in a different number of ways to therapies used. We successfully used fluticasone propionate, a synthetic corticoid applied topically, which proved to be efficient in the treatment of this illness by acting on the pathophysiological basis of the process. It does not have any adverse effects, thus offering advantages over other therapies such as systematic corticoids or endoscopic dilations.Introducción: la esofagitis eosinofílica es

    2004-01-01

    We present a simple and efficient scheme that combines multiple descriptions coding with wavelet transform under JPEG2000 image coding architecture. To reduce packet losses, controlled amounts of redundancy are added to the wavelet transform coefficients to produce multiple descriptions of wavelet coefficients during the compression process to produce multiple descriptions bit-stream of a compressed image. Even if areceiver gets only parts of descriptions (other descriptions being lost), it can still reconstruct image with acceptable quality. Specifically, the scheme uses not only high-performance wavelet transform to improve compression efficiency, but also multiple descriptions technique to enhance the robustness of the compressed image that is transmitted through unreliable network channels.

    Full Text Available El abordaje neuroaxial es de elección para el control del dolor en obstetricia, pero no está exento de riesgos. Las neuropatías periféricas posparto pueden producirse por diferentes condiciones médicas, quirúrgicas y anestésicas, por lo que debemos tenerlas presentes para diagnosticarlas y tratarlas precozmente y así evitar que se atribuyan, por defecto, a la técnica anestésica. Presentamos cuatro casos que se diagnosticaron en el periodo periparto, 2 meralgias parestésicas, 1 neuropatía del femoral y 1 lumbociatalgia, de las cuales solo la lumbociatalgia pudo ser atribuida parcialmente a la técnica anestésica. Tras confirmar su diagnóstico se instauró tratamiento conservador que resolvió ad integrum, dentro de los primeros siete días, todas las neuropatías salvo la lumbociatalgia. La baja incidencia de neuropatías periféricas tras técnicas neuroaxiales en obstetricia puede ser superior a la que se diagnostica. Resulta imprescindible una buena anamnesis preanestésica y conocer los diferentes mecanismos fisiopatológicos que pueden desencadenar neuropatías periféricas.A neuroaxial approach is of choice for the management of pain in obstetrics but is not exempt of risks. Postpartum peripheral neuropathy may occur because of various medical, surgical, and anesthetic conditions, hence we should have them in mind in order to recognize them and treat them early enough to prevent their deffault attribution to the anesthetic technique. We report four cases diagnosed during the peripartum - 2 paresthetic meralgias, 1 femoral neuropathy, and 1 lumbosciatalgia, of which only the lumbosciatalgia could be partly attributed to the anesthetic technique. Once the diagnosis was confirmed a conservative therapy was initiated that solved ad integrum all neuropathies, except for the lumbosciatalgia episode, within seven days. The low incidence of peripheral neuropathy following neuroaxial techniques in obstetrics may be higher than

    Full Text Available Acceptance tests are usually created by a client after a part of a system is implemented. However, some methodologies propose the elaboration of test cases before implementing a system. This approach increases the probability of system implementation that fulfills requirements, but may be problematic for customers and testers. To allow acceptance testing in such conditions, we propose to define test cases by recording them on an interactive mockup (a low detailed user-interface prototype. The paper focuses on Test Description Language, a notation used to store test cases.

    2016-01-01

    Full Text Available Web Services Choreography Description Language lacks a formal system to accurately express the semantics of service behaviors and verify the correctness of a service choreography model. The paper presents a new approach of choreography model verification based on Description Logic. A metamodel of service choreography is built to provide a conceptual framework to capture the formal syntax and semantics of service choreography. Based on the framework, a set of rules and constraints are defined in Description Logic for choreography model verification. To automate model verification, the UML-based service choreography model will be transformed, by the given algorithms, into the DL-based ontology, and thus the model properties can be verified by reasoning through the ontology with the help of a popular DL reasoner. A case study is given to demonstrate applicability of the method. Furthermore, the work will be compared with other related researches.

  9. Subject categories and scope descriptions

    International Nuclear Information System (INIS)

    This document is one in a series of publications known as the ETDE/INIS Joint Reference Series. It defines the subject categories and provides the scope descriptions to be used for categorization of the nuclear literature for the preparation of INIS and ETDE input by national and regional centres. Together with the other volumes of the INIS Reference Series it defines the rules, standards and practices and provides the authorities to be used in the International Nuclear Information System and ETDE. A complete list of the volumes published in the INIS Reference Series may be found on the inside front cover of this publication. This INIS/ETDE Reference Series document is intended to serve two purposes: to define the subject scope of the International Nuclear Information System (INIS) and the Energy Technology Data Exchange (ETDE) and to define the subject classification scheme of INIS and ETDE. It is thus the guide to the inputting centres in determining which items of literature should be reported, and in determining where the full bibliographic entry and abstract of each item should be included in INIS or ETDE database. Each category is identified by a category code consisting of three alphanumeric characters. A scope description is given for each subject category. The scope of INIS is the sum of the scopes of all the categories. With most categories cross references are provided to other categories where appropriate. Cross references should be of assistance in finding the appropriate category; in fact, by indicating topics that are excluded from the category in question, the cross references help to clarify and define the scope of the category to which they are appended. A Subject Index is included as an aid to subject classifiers, but it is only an aid and not a means for subject classification. It facilitates the use of this document, but is no substitute for the description of the scope of the subject categories

    The purpose of this revision of the System Design Description (SDD) is to establish requirements that drive the design of the electrical support system and their bases to allow the design effort to proceed to License Application. This SDD is a living document that will be revised at strategic points as the design matures over time. This SDD identifies the requirements and describes the system design as they exist at this time, with emphasis on those attributes of the design provided to meet the requirements. This SDD has been developed to be an engineering tool for design control. Accordingly, the primary audience/users are design engineers. This type of SDD both ''leads'' and ''trails'' the design process. It leads the design process with regard to the flow down of upper tier requirements onto the system. Knowledge of these requirements is essential in performing the design process. The SDD trails the design with regard to the description of the system. The description provided in the SDD is a reflection of the results of the design process to date. Functional and operational requirements applicable to electrical support systems are obtained from the ''Project Functional and Operational Requirements'' (F&OR) (Siddoway 2003). Other requirements to support the design process have been taken from higher-level requirements documents such as the ''Project Design Criteria Document'' (PDC) (Doraswamy 2004), and fire hazards analyses. The above-mentioned low-level documents address ''Project Requirements Document'' (PRD) (Canon and Leitner 2003) requirements. This SDD contains several appendices that include supporting information. Appendix B lists key system charts, diagrams, drawings, and lists, and Appendix C includes a list of system procedures.

  12. Standardizing the microsystems technology description

    Science.gov (United States)

    2002-04-01

    The microsystems industry is promising a rapid and widespread growth for the coming years. The automotive, network, telecom and electronics industries take advantage of this technology by including it in their products; thus, getting better integration and high energetic performances. Microsystems related software and data exchange have inherited from the IC technology experience or standards, which appear not to fit the advanced level of conception currently needed by microsystems designers. A typical design flow to validate a microsystem device involves several software from disconnected areas like layout editors, FEM simulators, HDL modeling and simulation tools. However, and fabricated microsystem is obtained through execution of a layered process. Process characteristics will be used at each level of the design and analysis. Basically, the designer will have to customize each of his tools after the process. The project introduced here intends to unify the process description language and speed up the critical and tedious CAD customization task. We gather all the information related to the technology of a microsystem process in a single file. It is based on the XML standard format to receive worldwide attention. This format is called XML-MTD, standing for XML Microsystems Technology Description. Built around XML, it is an ASCII format which gives the ability to handle a comprehensive database for technology data. This format is open, given under general public license, but the aim is to manage the format withing a XML-MTD consortium of leader and well-established EDA companies and Foundries. In this way, it will take profit of their experience. For automated configuration of design and analysis tools regarding process-dependant information, we ship the Technology Manger software. Technology Manager links foundries with a large panel of standard EDA and FEA packages used by design teams relying on the Microsystems Technology Description in XML-MTD format.

  14. Inflationary universe in fluid description

    CERN Document Server

    Bamba, Kazuharu

    2016-01-01

    We investigate a fluid description of inflationary cosmology. It is shown that the three observables of the inflationary universe: the spectral index of the curvature perturbations, the tensor-to-scalar ratio of the density perturbations, and the running of the spectral index, can be compatible with the Planck analysis. In addition, we reconstruct the equation of state (EoS) for a fluid from the spectral index of the curvature perturbations consistent with the Planck results. We explicitly demonstrate that the universe can gracefully exit from inflation in the reconstructed fluid models. Furthermore, we explore the singular inflation for a fluid model.

    Specification of architectures is an important prerequisite for evaluation of architectures. With the increase m the growth of health usage and monitoring systems (HUMS) in commercial and military domains, the need far the design and evaluation of HUMS architectures has also been on the increase. In this paper, we describe HADL, HUMS Architectural Description Language, that we have designed for this purpose. In particular, we describe the features of the language, illustrate them with examples, and show how we use it in designing domain-specific HUMS architectures. A companion paper contains details on our design methodology of HUMS architectures.

    vocabulary encoded in the Web Ontology Language to represent the observational features. A prototype of the system is currently under development in collaboration with the Mushroom Observer website. It allows users to propose new names and descriptions for fungi, provide feedback on those proposals, and ultimately have them formally approved. It relies on SPARQL queries and semantic reasoning for data management. This effort will offer the mycology community a knowledge base of fungal observational features and a tool for identifying fungal observations. It will also serve as an operational specification of how the Semantic Vernacular System can be used in practice in one scientific community (in this case mycology).

    We consider a given specification of functional requirements for a new electronic patient record system for Fyn County, Denmark. The requirements are expressed as task descriptions, which are informal descriptions of work processes to be supported. We describe how these task descriptions are used...... as a basis to construct two executable models in the formal modeling language Colored Petri Nets (CPNs). The first CPN model is used as an execution engine for a graphical animation, which constitutes an Executable Use Case (EUC). The EUC is a prototype-like representation of the task descriptions that can...

  9. Asymmetric Multilevel Diversity Coding and Asymmetric Gaussian Multiple Descriptions

    CERN Document Server

    Mohajer, Soheil; Diggavi, Suhas N

    2009-01-01

    We consider the asymmetric multilevel diversity (A-MLD) coding problem, where a set of $2^K-1$ information sources, ordered in a decreasing level of importance, is encoded into $K$ messages (or descriptions). There are $2^K-1$ decoders, each of which has access to a non-empty subset of the encoded messages. Each decoder is required to reproduce the information sources up to a certain importance level depending on the combination of descriptions available to it. We obtain a single letter characterization of the achievable rate region for the 3-description problem. In contrast to symmetric multilevel diversity coding, source-separation coding is not sufficient in the asymmetric case, and ideas akin to network coding need to be used strategically. Based on the intuitions gained in treating the A-MLD problem, we derive inner and outer bounds for the rate region of the asymmetric Gaussian multiple description (MD) problem with three descriptions. Both the inner and outer bounds have a similar geometric structure t...

  10. Integrated Project Management System description

    International Nuclear Information System (INIS)

    The Integrated Program Management System (IPMS) Description is a ''working'' document that describes the work processes of the Uranium Mill Tailings Remedial Action Project Office (UMTRA) and IPMS Group. This document has undergone many revisions since the UMTRA Project began; this revision not only updates the work processes but more clearly explains the relationships between the Project Office, contractors, and other participants. The work process flow style has been revised to better describe Project work and the relationships of participants. For each work process, more background and guidance on ''why'' and ''what is expected'' is given. For example, a description of activity data sheets has been added in the work organization and the Project performance and reporting processes, as well as additional detail about the federal budget process and funding management and improved flow charts and explanations of cost and schedule management. A chapter has been added describing the Cost Reduction/Productivity Improvement Program. The Change Control Board (CCB) procedures (Appendix A) have been updated. Project critical issues meeting (PCIM) procedures have been added as Appendix B. Budget risk assessment meeting procedures have been added as Appendix C. These appendices are written to act as stand-alone documentation for each process. As the procedures are improved and updated, the documentation can be updated separately

  11. Simpevarp - site descriptive model version 0

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2002-11-01

    During 2002, SKB is starting detailed investigations at two potential sites for a deep repository in the Precambrian rocks of the Fennoscandian Shield. The present report concerns one of those sites, Simpevarp, which lies in the municipality of Oskarshamn, on the southeast coast of Sweden, about 250 kilometres south of Stockholm. The site description will have two main components: a written synthesis of the site, summarising the current state of knowledge, as documented in the databases containing the primary data from the site investigations, and one or several site descriptive models, in which the collected information is interpreted and presented in a form which can be used in numerical models for rock engineering, environmental impact and long-term safety assessments. SKB maintains two main databases at the present time, a site characterisation database called SICADA and a geographic information system called SKB GIS. The site descriptive model will be developed and presented with the aid of the SKB GIS capabilities, and with SKBs Rock Visualisation System (RVS), which is also linked to SICADA. The version 0 model forms an important framework for subsequent model versions, which are developed successively, as new information from the site investigations becomes available. Version 0 is developed out of the information available at the start of the site investigation. In the case of Simpevarp, this is essentially the information which was compiled for the Oskarshamn feasibility study, which led to the choice of that area as a favourable object for further study, together with information collected since its completion. This information, with the exception of the extensive data base from the nearby Aespoe Hard Rock Laboratory, is mainly 2D in nature (surface data), and is general and regional, rather than site-specific, in content. Against this background, the present report consists of the following components: an overview of the present content of the databases

    2005-04-06

    The purpose of this system description document (SDD) is to establish requirements that drive the design of the spent nuclear fuel (SNF) aging system and associated bases, which will allow the design effort to proceed. This SDD will be revised at strategic points as the design matures. This SDD identifies the requirements and describes the system design, as it currently exists, with emphasis on attributes of the design provided to meet the requirements. This SDD is an engineering tool for design control; accordingly, the primary audience and users are design engineers. This SDD is part of an iterative design process. It leads the design process with regard to the flow down of upper tier requirements onto the system. Knowledge of these requirements is essential in performing the design process. The SDD follows the design with regard to the description of the system. The description provided in the SDD reflects the current results of the design process. Throughout this SDD, the term aging cask applies to vertical site-specific casks and to horizontal aging modules. The term overpack is a vertical site-specific cask that contains a dual-purpose canister (DPC) or a disposable canister. Functional and operational requirements applicable to this system were obtained from ''Project Functional and Operational Requirements'' (F&OR) (Curry 2004 [DIRS 170557]). Other requirements that support the design process were taken from documents such as ''Project Design Criteria Document'' (PDC) (BSC 2004 [DES 171599]), ''Site Fire Hazards Analyses'' (BSC 2005 [DIRS 172174]), and ''Nuclear Safety Design Bases for License Application'' (BSC 2005 [DIRS 171512]). The documents address requirements in the ''Project Requirements Document'' (PRD) (Canori and Leitner 2003 [DIRS 166275]). This SDD includes several appendices. Appendix A is a Glossary; Appendix B is a list of key system charts

  14. Surface parametrization and shape description

    Science.gov (United States)

    Brechbuehler, Christian; Gerig, Guido; Kuebler, Olaf

    1992-09-01

    Procedures for the parameterization and description of the surface of simply connected 3-D objects are presented. Critical issues for shape-based categorization and comparison of 3-D objects are addressed, which are generality with respect to object complexity, invariance to standard transformations, and descriptive power in terms of object geometry. Starting from segmented volume data, a relational data structure describing the adjacency of local surface elements is generated. The representation is used to parametrize the surface by defining a continuous, one-to-one mapping from the surface of the original object to the surface of a unit sphere. The mapping is constrained by two requirements, minimization of distortions and preservation of area. The former is formulated as the goal function of a nonlinear optimization problem and the latter as its constraints. Practicable starting values are obtained by an initial mapping based on a heat conduction model. In contract to earlier approaches, the novel parameterization method provides a mapping of arbitrarily shaped simply connected objects, i.e., it performs an unfolding of convoluted surface structures. This global parameterization allows the systematical scanning of the object surface by the variation of two parameters. As one possible approach to shape analysis, it enables us to expand the object surface into a series of spherical harmonic functions, extending the concept of elliptical Fourier descriptors for 2-D closed curves. The novel parameterization overcomes the traditional limitations of expressing an object surface in polar coordinates, which restricts such descriptions to star-shaped objects. The numerical coefficients in the Fourier series form an object-centered, surface-oriented descriptor of the object''s form. Rotating the coefficients in parameter space and object space puts the object into a standard position and yields a spherical harmonic descriptor which is invariant to translations, rotations

  15. A Random Variable Substitution Lemma With Applications to Multiple Description Coding

    CERN Document Server

    Wang, Jia; Zhao, Lei; Cuff, Paul; Permuter, Haim

    2009-01-01

    We establish a random variable substitution lemma and use it to investigate the role of refinement layer in multiple description coding, which clarifies the relationship among several existing achievable multiple description rate-distortion regions. Specifically, it is shown that the El Gamal-Cover (EGC) region is equivalent to the EGC* region (an antecedent version of the EGC region) while the Venkataramani-Kramer-Goyal (VKG) region (when specialized to the 2-description case) is equivalent to the Zhang-Berger (ZB) region. Moreover, we prove that for multiple description coding with individual and hierarchical distortion constraints, the number of layers in the VKG scheme can be significantly reduced when only certain weighted sum rates are concerned. The role of refinement layer in scalable coding (a special case of multiple description coding) is also studied.

  16. Integrated Project Management System description

    International Nuclear Information System (INIS)

    The Uranium Mill Tailings Remedial Action (UMTRA) Project is a Department of Energy (DOE) designated Major System Acquisition (MSA). To execute and manage the Project mission successfully and to comply with the MSA requirements, the UMTRA Project Office (''Project Office'') has implemented and operates an Integrated Project Management System (IPMS). The Project Office is assisted by the Technical Assistance Contractor's (TAC) Project Integration and Control (PIC) Group in system operation. Each participant, in turn, provides critical input to system operation and reporting requirements. The IPMS provides a uniform structured approach for integrating the work of Project participants. It serves as a tool for planning and control, workload management, performance measurement, and specialized reporting within a standardized format. This system description presents the guidance for its operation. Appendices 1 and 2 contain definitions of commonly used terms and abbreviations and acronyms, respectively. 17 figs., 5 tabs

  18. Relativistic description of deformed nuclei

    International Nuclear Information System (INIS)

    The author has shown that relativistic Hartree calculations using parameters that have been fit to the properties of nuclear matter can provide a good description of both spherical and axially deformed nuclei. The quantitative agreement with experiment is equivalent to that which was obtained in non-relativistic calculations using Skyrme interactions. The equilibrium deformation is strongly correlated with the size of the spin-orbit splitting, and that parameter sets which give roughly the correct value for this splitting provide the best agreement with the quadrupole moments in the s-d shell. Finally, for closed shell +/- 1 nuclei, it was shown that the self-consistent calculations are able to reproduce the experimental magnetic moments. This was not possible in relativistic calculations which include only the effects of the valence orbital

  19. Theory buried under heavy description

    Directory of Open Access Journals (Sweden)

    Vivian B. Martin Ph.D.

    2010-12-01

    Full Text Available In journalism when a reporter puts the main news or point of the story deep down in the text, we say she’s buried the lead, the lead being the main point of the story and usually the first paragraph. In Children in Genocide: extreme traumatization and affect regulation, psychoanalyst Suzanne Kaplan buries her theory. Her study of the after effects of trauma among Holocaust survivors who were children during their persecution and survivors of atrocities during the Rwandan atrocities of the 1990s, is filled with highly descriptive material from the many interviews that serve as data. An interesting grounded theory is peeking out from under all the disciplinary discourse and historical background one must read through to get to what grounded theory readers will consider the juicy parts: concepts on affect regulation in trauma survivors.

  2. Mucormycosis and bone scintillography of three phases. Case description

    International Nuclear Information System (INIS)

    The purpose of presenting this work, besides the interest that shows the mucormycosis pathology not so frequent, it is to carry out a clinical correlation photographic with the imagenology, particularly with the bone scintillography. In the Nuclear Medicine Service it is carried out bone scintillography of three phases previous endovenous administration of 30 mCi (1110 MBq) of 99m Tc-MDP. The images are obtained with a gamma camera model Elscint APEX SPX, first each 2 seconds during the first minute, then early image to the 5 minutes and finally the late ones to the 3 hs. The bone scintillography in the phases 2 and 3 detects bigger radioactive density in left hemi side, with increment of the osteoblast activity mainly in the medial border and the floor of the orbit, in the malar bone and a little more tenuous in the superior maxillary.

  3. Depressive symptoms associated with hereditary Alzheimer's disease: a case description.

    Science.gov (United States)

    Contreras, Mónica Yicette Sánchez; Vargas, Paula Alejandra Osorio; Ramos, Lucero Rengifo; Velandia, Rafael Alarcón

    The authors describe a family group studied by the Centro de Biología Molecular y Biotecnología, and the Clínica de la Memoria, las Demencias y el Envejecimiento (Universidad Tecnológica de Pereira, Colombia), and evaluate the association of depressive symptoms with Alzheimer's disease (AD). This family presented a hereditary pattern for AD characterized by an early onset of dementia symptoms, a long preclinical depressive course, and, once the first symptoms of dementia appeared, a rapid progression to severe cognitive function impairment. The authors found a high prevalence of depressive symptoms in this family and propose that the symptoms could be an important risk factor for developing AD in the presence of other risk factors such as the APOE E4 allele.

Commercial breeding began about 150 years ago, with the domestication of native animals from South Africa, country which holds the first position in meat supply. Several musculoskeletal diseases were observed in fast-growing birds, such as ostrich. High body weight, associated to a developing bone structure, is indicated as the main cause of disorders of the locomotor system. In this study, an adult male specimen was used, from an ostrich production farm located at the town of Paranatama, Pernambuco, Brazil. After removing soft tissues, bone measurements were performed with caliper and tape measure, and each bone was photographed for documentation and described. This study aims to contribute to increase knowledge on the ostrich skeletal system, as well as provide a basis for muscle development, one of the main targets of commercial exploitation with regard to this species.

  5. Development of the method for the similarity detection of descriptions in radiology reports using structuring technology

    International Nuclear Information System (INIS)

    Radiologists often spend much time for re-reading some of the past free-text radiology reports and determining interval changes in the physical findings when creating a report for long term cases. The aim of this study was to propose the method to detect semantic similar descriptions in the free-text reports using the structuring method based on text-mining technology. In a previous study, we had developed the structuring method that can semantically analyze the free-text reports and convert them into the description unit consisting of five items: finding/diagnosis, modifier, region, regional modifier, and confidence. Our developed prototype system extracted similar descriptions from the free-text reports by calculating the similarity index between description units. We confirmed similar descriptions extracted by the system applied to free-text reports of cases which had more than one chest CT examination written in actual clinical situation. As a result, it became available to identify candidates of similar descriptions from free-text reports. In some cases regarding practical use, the similar descriptions could not be identified in the sentences which used paraphrasing or where the findings had status changes. A solution of identifying similarity in these cases was necessary to improve the method. With the presented method here, it is expected that interval changes in the findings can be visualized and applied it to support diagnosis. (author)

    In the 11(th) and 12(th) century the Western caliphate flourished, making Cordoba the capital of physicians and philosophers. During that period lived and practised the famous physician Ibn Zuhr or Avenzoar. In his monumental treatise Al Taysir, Avenzoar provided the first clinical description of a polypoid colorectal tumour as well as the case of a uterine cancer and a basal cell carcinoma. His medical work remained popular through middle ages, influencing the development of western medicine. PMID:26416074

  8. Multiple descriptions based wavelet image coding

    Institute of Scientific and Technical Information of China (English)

    CHEN Hai-lin(陈海林); YANG Yu-hang(杨宇航)

    2004-01-01

    We present a simple and efficient scheme that combines multiple descriptions coding with wavelet transform under JPEG2000 image coding architecture. To reduce packet losses, controlled amounts of redundancy are added to the wavelet transform coefficients to produce multiple descriptions of wavelet coefficients during the compression process to produce multiple descriptions bit-stream of a compressed image. Even if a receiver gets only parts of descriptions (other descriptions being lost), it can still reconstruct image with acceptable quality. Specifically, the scheme uses not only high-performance wavelet transform to improve compression efficiency, but also multiple descriptions technique to enhance the robustness of the compressed image that is transmitted through unreliable network channels.

    It has been estimated that women involved in street prostitution are 60 to 100 times more likely to be murdered than are nonprostitute females. In addition, homicides of prostitutes are notoriously difficult to investigate and, as such, many cases remain unsolved. Despite this large risk factor, little literature exists on homicides of…

  10. Compressed Transmission of Route Descriptions

    CERN Document Server

    Batz, Gernot Veit; Luxen, Dennis; Sanders, Peter

    2010-01-01

    We present two methods to compress the description of a route in a road network, i.e., of a path in a directed graph. The first method represents a path by a sequence of via edges. The subpaths between the via edges have to be unique shortest paths. Instead of via edges also via nodes can be used, though this requires some simple preprocessing. The second method uses contraction hierarchies to replace subpaths of the original path by shortcuts. The two methods can be combined with each other. Also, we propose the application to mobile server based routing: We compute the route on a server which has access to the latest information about congestions for example. Then we transmit the computed route to the car using some mobile radio communication. There, we apply the compression to save costs and transmission time. If the compression works well, we can transmit routes even when the bandwidth is low. Although we have not evaluated our ideas with realistic data yet, they are quite promising.

  11. Beyond statistical descriptions of variability

    Science.gov (United States)

    Graham, Matthew; Catalina Real-time Transient Survey Team

    2016-01-01

    The first generation of large synoptic survey archives, such as CRTS, PTF and Pan-STARRs, are now (or soon will be) available to the community, enabling unprecedented systematic searches and studies of variable astrophysical phenomena. These range from moving objects in the Solar System to extreme quasars in the distant universe. However, much of the analyses of these data sets conducted so far have aimed at providing statistical descriptions of the variability. Whilst such parameterizations are useful for feeding classification algorithms, they are not effective at describing the underlying type of variability in the sources or the physical mechanism(s) for it. In this talk, we will discuss new approaches, such as wavelet variance, random matrix theory and echo state networks, that can provide insight into the science of variability rather than just statistically characterizing it. We will pay particular attention to sources exhibiting stochastic variation and how much information about the host system can be determined from their time series. For example, characteristic restframe timescales have been identified in quasars, potentially related to the size of coherent noise fields in the accretion disk. Finally, we will also consider the potential limitations of the next generation surveys, such as LSST and SKA.

  12. XML Translator for Interface Descriptions

    Science.gov (United States)

    Boroson, Elizabeth R.

    2009-01-01

    A computer program defines an XML schema for specifying the interface to a generic FPGA from the perspective of software that will interact with the device. This XML interface description is then translated into header files for C, Verilog, and VHDL. User interface definition input is checked via both the provided XML schema and the translator module to ensure consistency and accuracy. Currently, programming used on both sides of an interface is inconsistent. This makes it hard to find and fix errors. By using a common schema, both sides are forced to use the same structure by using the same framework and toolset. This makes for easy identification of problems, which leads to the ability to formulate a solution. The toolset contains constants that allow a programmer to use each register, and to access each field in the register. Once programming is complete, the translator is run as part of the make process, which ensures that whenever an interface is changed, all of the code that uses the header files describing it is recompiled.

  13. Continuous description of fluctuating eccentricities

    Directory of Open Access Journals (Sweden)

    Jean-Paul Blaizot

    2014-11-01

    Full Text Available We consider the initial energy density in the transverse plane of a high energy nucleus–nucleus collision as a random field ρ(x, whose probability distribution P[ρ], the only ingredient of the present description, encodes all possible sources of fluctuations. We argue that it is a local Gaussian, with a short-range 2-point function, and that the fluctuations relevant for the calculation of the eccentricities that drive the anisotropic flow have small relative amplitudes. In fact, this 2-point function, together with the average density, contains all the information needed to calculate the eccentricities and their variances, and we derive general model independent expressions for these quantities. The short wavelength fluctuations are shown to play no role in these calculations, except for a renormalization of the short range part of the 2-point function. As an illustration, we compare to a commonly used model of independent sources, and recover the known results of this model.

    Descriptions are often provided along with recommendations to help users' discovery. Recommending automatically generated music playlists (e.g. personalised playlists) introduces the problem of generating descriptions. In this paper, we propose a method for generating music playlist descriptions, which is called as music captioning. In the proposed method, audio content analysis and natural language processing are adopted to utilise the information of each track.

  15. Optical Hall effect-model description: tutorial.

    Science.gov (United States)

    Schubert, Mathias; Kühne, Philipp; Darakchieva, Vanya; Hofmann, Tino

    2016-08-01

    The optical Hall effect is a physical phenomenon that describes the occurrence of magnetic-field-induced dielectric displacement at optical wavelengths, transverse and longitudinal to the incident electric field, and analogous to the static electrical Hall effect. The electrical Hall effect and certain cases of the optical Hall effect observations can be explained by extensions of the classic Drude model for the transport of electrons in metals. The optical Hall effect is most useful for characterization of electrical properties in semiconductors. Among many advantages, while the optical Hall effect dispenses with the need of electrical contacts, electrical material properties such as effective mass and mobility parameters, including their anisotropy as well as carrier type and density, can be determined from the optical Hall effect. Measurement of the optical Hall effect can be performed within the concept of generalized ellipsometry at an oblique angle of incidence. In this paper, we review and discuss physical model equations, which can be used to calculate the optical Hall effect in single- and multiple-layered structures of semiconductor materials. We define the optical Hall effect dielectric function tensor, demonstrate diagonalization approaches, and show requirements for the optical Hall effect tensor from energy conservation. We discuss both continuum and quantum approaches, and we provide a brief description of the generalized ellipsometry concept, the Mueller matrix calculus, and a 4×4 matrix algebra to calculate data accessible by experiment. In a follow-up paper, we will discuss strategies and approaches for experimental data acquisition and analysis. PMID:27505654

  16. On the tomographic description of classical fields

    International Nuclear Information System (INIS)

    After a general description of the tomographic picture for classical systems, a tomographic description of free classical scalar fields is proposed both in a finite cavity and the continuum. The tomographic description is constructed in analogy with the classical tomographic picture of an ensemble of harmonic oscillators. The tomograms of a number of relevant states such as the canonical distribution, the classical counterpart of quantum coherent states and a new family of so-called Gauss–Laguerre states, are discussed. Finally the Liouville equation for field states is described in the tomographic picture offering an alternative description of the dynamics of the system that can be extended naturally to other fields.

    2008-01-01

    Many natural phenomena can be described by power-laws. A closer look at various experimental data reveals more or less significant deviations from a 1/f spectrum. We exemplify such cases with phenomena offered by molecular biology, cell biophysics, and cognitive psychology. Some of these cases can be described by first order autoregressive (AR) models or by higher order AR models which are short range correlation models. The calculations are checked against astrophysical data which were fitted to a an AR model by a different method. We found that our fitting method of the data give similar results for the astrhophysical data and therefore applied the method for examples mentioned above. Our results show that such phenomena can be described by first or higher order of AR models. Therefore such examples are described by short range correlation properties while they can be easily confounded with long range correlation phenomena.

  2. Emplacement Drift System Description Document

    International Nuclear Information System (INIS)

    The Emplacement Drift System is part of the Engineered Barrier System and provides the interface between the various waste package (WP) systems and the Ground Control System. In conjunction with the various WPs, the Emplacement Drift System limits the release and transport of radionuclides from the WP to the Natural Barrier following waste emplacement. Collectively, the Emplacement Drift System consists of the structural support hardware (emplacement drift invert and WP emplacement pallet) and any performance-enhancing barriers (drip shields and invert ballast) installed or placed in the emplacement drifts. The Emplacement Drift System is entirely located within the emplacement drifts in the subsurface portion of the Monitored Geologic Repository (MGR); specifically, it is physically bounded by the Subsurface Facility System, the Ground Support System, and the Natural Barrier. The Emplacement Drift System supports the key MGR functions of limiting radionuclide release to the Natural Barrier, minimizing the likelihood of a criticality external to the WPs, limiting natural and induced environmental effects, and providing WP support. The Emplacement Drift System limits radionuclide release to the Natural Barrier by controlling the movement of radionuclides within the emplacement drift and to the Natural Barrier, and by limiting water contact with the WPs. The Emplacement Drift System provides physical support and barriers for emplaced WPs that reduce water contact. The Emplacement Drift WP spacing supports the thermal loading performance by complimenting drift layout and orientation as described in the system description document for the Subsurface Facility System. The Emplacement Drift System supports the WP and also provides an environment that aids in enhancing WP confinement performance. As part of the Engineered Barrier System, the Emplacement Drift System interfaces with the WP systems. The Emplacement Drift System also interfaces with the Natural Barrier

  4. Statistical description of turbulent dispersion

    Science.gov (United States)

    Brouwers, J. J. H.

    2012-12-01

    We derive a comprehensive statistical model for dispersion of passive or almost passive admixture particles such as fine particulate matter, aerosols, smoke, and fumes in turbulent flow. The model rests on the Markov limit for particle velocity. It is in accordance with the asymptotic structure of turbulence at large Reynolds number as described by Kolmogorov. The model consists of Langevin and diffusion equations in which the damping and diffusivity are expressed by expansions in powers of the reciprocal Kolmogorov constant C0. We derive solutions of O(C00) and O(C0-1). We truncate at O(C0-2) which is shown to result in an error of a few percentages in predicted dispersion statistics for representative cases of turbulent flow. We reveal analogies and remarkable differences between the solutions of classical statistical mechanics and those of statistical turbulence.

  6. Converting Taxonomic Descriptions to New Digital Formats

    Directory of Open Access Journals (Sweden)

    Hong Cui

    2008-01-01

    Full Text Available Abstract.--The majority of taxonomic descriptions is currently in print format. The majority of digital descriptions are in formats such as DOC, HTML, or PDF and for human readers. These formats do not convey rich semantics in taxonomic descriptions for computer-aided process. Newer digital formats such as XML and RDF accommodate semantic annotations that allow computers to process the rich semantics on human's behalf, thus open up opportunities for a wide range of innovative usages of taxonomic descriptions, such as searching in more precise and flexible ways, integrating with gnomic and geographic information, generating taxonomic keys automatically, and text data mining and information visualization etc. This paper discusses the challenges in automated conversion of multiple collections of descriptions to XML format and reports an automated system, MARTT. MARTT is a machine-learning system that makes use of training examples to tag new descriptions into XML format. A number of utilities are implemented as solutions to the challenges. The utilities are used to reduce the effort for training example preparation, to facilitate the creation of a comprehensive schema, and to predict system performance on a new collection of descriptions. The system has been tested with several plant and alga taxonomic publications including Flora of China and Flora of North America.

    Willis, Danny G; Sullivan-Bolyai, Susan; Knafl, Kathleen; Cohen, Marlene Z

    2016-09-01

    Scholars who research phenomena of concern to the discipline of nursing are challenged with making wise choices about different qualitative research approaches. Ultimately, they want to choose an approach that is best suited to answer their research questions. Such choices are predicated on having made distinctions between qualitative methodology, methods, and analytic frames. In this article, we distinguish two qualitative research approaches widely used for descriptive studies: descriptive phenomenological and qualitative description. Providing a clear basis that highlights the distinguishing features and similarities between descriptive phenomenological and qualitative description research will help students and researchers make more informed choices in deciding upon the most appropriate methodology in qualitative research. We orient the reader to distinguishing features and similarities associated with each approach and the kinds of research questions descriptive phenomenological and qualitative description research address.

  9. A Formal Description of Problem Frames

    Directory of Open Access Journals (Sweden)

    Souleymane KOUSSOUBE

    2014-03-01

    Full Text Available Michael Jackson defines a Problem Frame as a mean to describe and classify software development problems. The initial description of problem Frames is essentially graphical. A weakness of this proposal is the lack of formal specification allowing efficient reasoning tools. This paper deals with Problem Frames’ formal specification with Description Logics. We first propose a formal terminology of Problem Frames leading to the specification of a Problem Frames’ TBOX and a specific problem’s ABOX. The Description Logics inference tools can then be used to decompose multi frame problems or to fix a particular problem into a Problem Frame.

  13. VIRTUAL INSTRUMENT SYSTEM SOFTWARE ARCHITECTURE DESCRIPTION LANGUAGE

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    In software engineering, an architecture description language (ADL) is intended to aid designers in defining software architectures in terms of abstractions that they find useful, and in making a smooth transi- tion to code. Based on ADL, the concept and models of the Virtual instrunent system Software architecture Description Language (VSDL) is provided in this paper. The VSDL put forward provides a new method for vir- tual instrunent system's application design and development by describing the virtual instrument system soft- ware architecture effectively. In this paper, the model description、component description and line description are analyzed in detail, and the structure language based on the model is also provided. VSDL provides a smooth interface to graphic software platform, and has been applied to many virtual instrument systems' inte- gration and already yielded good results both in technology and economy.

  14. Mining skeletal phenotype descriptions from scientific literature.

    Directory of Open Access Journals (Sweden)

    Tudor Groza

    Full Text Available Phenotype descriptions are important for our understanding of genetics, as they enable the computation and analysis of a varied range of issues related to the genetic and developmental bases of correlated characters. The literature contains a wealth of such phenotype descriptions, usually reported as free-text entries, similar to typical clinical summaries. In this paper, we focus on creating and making available an annotated corpus of skeletal phenotype descriptions. In addition, we present and evaluate a hybrid Machine Learning approach for mining phenotype descriptions from free text. Our hybrid approach uses an ensemble of four classifiers and experiments with several aggregation techniques. The best scoring technique achieves an F-1 score of 71.52%, which is close to the state-of-the-art in other domains, where training data exists in abundance. Finally, we discuss the influence of the features chosen for the model on the overall performance of the method.

  16. Description of Sizewell B nuclear power plant

    International Nuclear Information System (INIS)

    The intention of this report is to present a condensed technical description of Sizewell B in a language understandable to non-technical personnel. It is unavoidable that some parts will be less precise than the technically initiated would like to see, but hopefully the content still give a realistic picture of Sizewell B. The technical description is based on publicly available material, of which the Sizewell B safety report has been particularly useful. Nearly all figures and drawings found in this description are reproductions of corresponding material in the safety report. To keep the description from becoming too voluminous it has been necessary to condense some background material down to a small volume. Hopefully this has not introduced any errors or inaccuracies, possible oversimplification at certain points must be weighed against the wish to cover most of the topics in the agreed table of contents for these NKS reports.

    We derive self-consistent formalism for the description of multi-component partially ionized solar plasma, by means of the coupled equations for the charged and neutral components for an arbitrary number of chemical species, and the radiation field. All approximations and assumptions are carefully considered. Generalized Ohm's law is derived for the single-fluid and two-fluid formalism. Our approach is analytical with some order-of-magnitude support calculations. After general equations are developed, we particularize to some frequently considered cases as for the interaction of matter and radiation.

  2. Site descriptive modelling - strategy for integrated evaluation

    International Nuclear Information System (INIS)

    The current document establishes the strategy to be used for achieving sufficient integration between disciplines in producing Site Descriptive Models during the Site Investigation stage. The Site Descriptive Model should be a multidisciplinary interpretation of geology, rock mechanics, thermal properties, hydrogeology, hydrogeochemistry, transport properties and ecosystems using site investigation data from deep bore holes and from the surface as input. The modelling comprise the following iterative steps, evaluation of primary data, descriptive and quantitative modelling (in 3D), overall confidence evaluation. Data are first evaluated within each discipline and then the evaluations are checked between the disciplines. Three-dimensional modelling (i.e. estimating the distribution of parameter values in space and its uncertainty) is made in a sequence, where the geometrical framework is taken from the geological model and in turn used by the rock mechanics, thermal and hydrogeological modelling etc. The three-dimensional description should present the parameters with their spatial variability over a relevant and specified scale, with the uncertainty included in this description. Different alternative descriptions may be required. After the individual discipline modelling and uncertainty assessment a phase of overall confidence evaluation follows. Relevant parts of the different modelling teams assess the suggested uncertainties and evaluate the feedback. These discussions should assess overall confidence by, checking that all relevant data are used, checking that information in past model versions is considered, checking that the different kinds of uncertainty are addressed, checking if suggested alternatives make sense and if there is potential for additional alternatives, and by discussing, if appropriate, how additional measurements (i.e. more data) would affect confidence. The findings as well as the modelling results are to be documented in a Site Description

  7. Description scheme for video editing work

    Ruiloba, Rosa I.; Joly, Philippe

    2001-03-01

    This article presents a Description Scheme (DS) to describe the audio-visual documents from the video editing work point of view. This DS is based on edition techniques used in the video edition domain. The main objective of this DS is to provide a complete, modular and extensible description of the structure of the video documents based on editing process. This VideoEditing DS is generic in the sense that it may be used in a large number of applications such as video document indexing and analysis, description of Edit Decision List and elaboration of editing patterns. It is based on accurate and complete definitions of shots and transition effects required for video document analysis applications. The VideoEditing DS allows three levels of description : analytic, synthetic and semantic. In the DS, the higher (resp. the lower) is the element of description, the more analytic (resp. synthetic) is the information. %Phil This DS allows describing the editing work made by editing boards, using more detailed descriptors of Shots and Transition DSs. These elements are provided to define editing patterns that allow several possible reconstructions of movies depending on, for example, the target audience. A part of the video description made with this DS may be automatically produced by the video to shots segmentation algorithms (analytic DSs ) or by editing software, at the same time the edition work is made. This DS gives an answer to the needs related to the exchange of editing work descriptions between editing softwares. At the same time, the same DS provide an analytic description of editing work which is complementary to existing standards for Edit Decision Lists like SMPTE or AAF.

  9. Hydrodynamic description of spin Calogero-Sutherland model

    Science.gov (United States)

    Abanov, Alexander; Kulkarni, Manas; Franchini, Fabio

    2009-03-01

    We study a non-linear collective field theory for an integrable spin-Calogero-Sutherland model. The hydrodynamic description of this SU(2) model in terms of charge density, charge velocity and spin currents is used to study non-perturbative solutions (solitons) and examine their correspondence with known quantum numbers of elementary excitations [1]. A conventional linear bosonization or harmonic approximation is not sufficient to describe, for example, the physics of spin-charge (non)separation. Therefore, we need this new collective bosonic field description that captures the effects of the band curvature. In the strong coupling limit [2] this model reduces to integrable SU(2) Haldane-Shastry model. We study a non-linear coupling of left and right spin currents which form a Kac-Moody algebra. Our quantum hydrodynamic description for the spin case is an extension for the one found in the spinless version in [3].[3pt] [1] Y. Kato,T. Yamamoto, and M. Arikawa, J. Phys. Soc. Jpn. 66, 1954-1961 (1997).[0pt] [2] A. Polychronakos, Phys Rev Lett. 70,2329-2331(1993).[0pt] [3] A.G.Abanov and P.B. Wiegmann, Phys Rev Lett 95, 076402(2005)

  11. Kinetic description of collision avoidance in pedestrian crowds by sidestepping

    CERN Document Server

    Festa, Adriano; Wolfram, Marie-Therese

    2016-01-01

    In this paper we study a kinetic model for pedestrians, who are assumed to adapt their motion towards a desired direction while avoiding collisions with others by stepping aside. These minimal microscopic interaction rules lead to complex emergent macroscopic phenomena, such as velocity alignment in unidirectional flows and lane or stripe formation in bidirectional flows. We start by discussing collision avoidance mechanisms at the microscopic scale, then we study the corresponding Boltzmann-type kinetic description and its hydrodynamic mean-field approximation in the grazing collision limit. In the spatially homogeneous case we prove directional alignment under specific conditions on the sidestepping rules for both the collisional and the mean-field model. In the spatially inhomogeneous case we illustrate, by means of various numerical experiments, the rich dynamics that the proposed model is able to reproduce.

    Full Text Available Multiple description coding offers an elegant and competitive solution for data transmission over lossy packet-based networks, with a graceful degradation in quality as losses increase. In the same time, coding techniques based on redundant transforms give a very promising alternative for the generation of multiple descriptions, mainly due to redundancy inherently given by a transform, which offers intrinsic resiliency in case of loss. In this paper, we show how partitioning of a generic redundant dictionary can be used to obtain an arbitrary number of multiple complementary, yet correlated, descriptions. The most significant terms in the signal representation are drawn from the partitions that better approximate the signal, and split to different descriptions, while the less important ones are alternatively distributed between the descriptions. As compared to state-of-the-art solutions, such a strategy allows for a better central distortion since atoms in different descriptions are not identical; in the same time, it does not penalize the side distortions significantly since atoms from the same partition are likely to be highly correlated. The proposed scheme is applied to the multiple description coding of digital images, and simulation results show increased performances compared to state-of-the-art schemes, both in terms of distortions and robustness to loss rate variations.

  13. Math Description Engine Software Development Kit

    2010-01-01

    The Math Description Engine Software Development Kit (MDE SDK) can be used by software developers to make computer-rendered graphs more accessible to blind and visually-impaired users. The MDE SDK generates alternative graph descriptions in two forms: textual descriptions and non-verbal sound renderings, or sonification. It also enables display of an animated trace of a graph sonification on a visual graph component, with color and line-thickness options for users having low vision or color-related impairments. A set of accessible graphical user interface widgets is provided for operation by end users and for control of accessible graph displays. Version 1.0 of the MDE SDK generates text descriptions for 2D graphs commonly seen in math and science curriculum (and practice). The mathematically rich text descriptions can also serve as a virtual math and science assistant for blind and sighted users, making graphs more accessible for everyone. The MDE SDK has a simple application programming interface (API) that makes it easy for programmers and Web-site developers to make graphs accessible with just a few lines of code. The source code is written in Java for cross-platform compatibility and to take advantage of Java s built-in support for building accessible software application interfaces. Compiled-library and NASA Open Source versions are available with API documentation and Programmer s Guide at http:/ / prim e.jsc.n asa. gov.

  14. The written description rejection as a barrier to biotech patent prosecution.

    Wang, Shyh-Jen

    2011-05-01

    Biotech firms always pursue broad claims to secure new discoveries, new technologies and even as yet undiscovered results of future research. However, expansive claims without sufficient description violate the principal of granting the patentee the right to exclude others from using the technical development for a certain amount of time in return for disclosing the innovation. Based on this investigation, a written description can be a barrier to biotech patents with broad claims. To avoid a written description rejection during patent prosecution or invalidation in litigation, the patent applicant or assignee should demonstrate possession of the claimed invention by describing the claimed invention with all of its limitations using descriptive means such as words, structures, figures, diagrams, and formulas that fully set forth the claimed invention. Although the court cases analyzed in this study were not directly related to vaccines, the guideline indeed is applicable to patents of vaccine. Furthermore, a vaccine patent application is also demonstrated. PMID:21552000

  16. A Domain Description Language for Data Processing

    Science.gov (United States)

    Golden, Keith

    2003-01-01

    We discuss an application of planning to data processing, a planning problem which poses unique challenges for domain description languages. We discuss these challenges and why the current PDDL standard does not meet them. We discuss DPADL (Data Processing Action Description Language), a language for describing planning domains that involve data processing. DPADL is a declarative, object-oriented language that supports constraints and embedded Java code, object creation and copying, explicit inputs and outputs for actions, and metadata descriptions of existing and desired data. DPADL is supported by the IMAGEbot system, which we are using to provide automation for an ecological forecasting application. We compare DPADL to PDDL and discuss changes that could be made to PDDL to make it more suitable for representing planning domains that involve data processing actions.

      Compared with the study of Grammar, syntax, the description on vocabulary is comparatively slower than them. The related theories of vocabulary description have fast developed since the 1980s and 1990s have experienced a growing interest in vocabulary learning and teaching----The vocabulary size, text coverage, word list, meaning of vocabulary in context, and collocation have been discovered and described, which helped new insights in arrange of different research fields have all added to our understanding of vocabulary development. Vocabulary acquisition research, based on vocabulary description, has established itself as a central research focus for language acquisition researchers and contributed to the focus of practical teaching and learning in College English.

  18. Formalizing the Problem of Music Description

    DEFF Research Database (Denmark)

    Sturm, Bob L.; Bardeli, Rolf; Langlois, Thibault;

    2015-01-01

    The lack of a formalism for “the problem of music descrip- tion” results in, among other things: ambiguity in what problem a music description system must address, how it should be evaluated, what criteria define its success, and the paradox that a music description system can reproduce the “ground...... truth” of a music dataset without attending to the music it contains. To address these issues, we formal- ize the problem of music description such that all elements of an instance of it are made explicit. This can thus inform the building of a system, and how it should be evaluated in a meaningful way....... We provide illustrations of this formal- ism applied to three examples drawn from the literature....

  19. Towards reproducible descriptions of neuronal network models.

    Directory of Open Access Journals (Sweden)

    Eilen Nordlie

    2009-08-01

    Full Text Available Progress in science depends on the effective exchange of ideas among scientists. New ideas can be assessed and criticized in a meaningful manner only if they are formulated precisely. This applies to simulation studies as well as to experiments and theories. But after more than 50 years of neuronal network simulations, we still lack a clear and common understanding of the role of computational models in neuroscience as well as established practices for describing network models in publications. This hinders the critical evaluation of network models as well as their re-use. We analyze here 14 research papers proposing neuronal network models of different complexity and find widely varying approaches to model descriptions, with regard to both the means of description and the ordering and placement of material. We further observe great variation in the graphical representation of networks and the notation used in equations. Based on our observations, we propose a good model description practice, composed of guidelines for the organization of publications, a checklist for model descriptions, templates for tables presenting model structure, and guidelines for diagrams of networks. The main purpose of this good practice is to trigger a debate about the communication of neuronal network models in a manner comprehensible to humans, as opposed to machine-readable model description languages. We believe that the good model description practice proposed here, together with a number of other recent initiatives on data-, model-, and software-sharing, may lead to a deeper and more fruitful exchange of ideas among computational neuroscientists in years to come. We further hope that work on standardized ways of describing--and thinking about--complex neuronal networks will lead the scientific community to a clearer understanding of high-level concepts in network dynamics, and will thus lead to deeper insights into the function of the brain.

    2005-03-01

    Swedish Nuclear Fuel and Waste Management Co is currently conducting site characterisation in the Simpevarp area. The area is divided into two subareas, the Simpevarp and the Laxemar subarea. The two subareas are surrounded by a common regional model area, the Simpevarp area. This report describes both the regional area and the subareas. This report is an interim version (model version 1.2) of the description of the surface systems at the Simpevarp area, and should be seen as a background report to the site description of the Simpevarp area, version 1.2, SKB-R--05-08. The basis for this description is quality-assured field data available in the SKB SICADA and GIS databases, together with generic data from the literature. The Surface system, here defined as everything above the bedrock, comprises a number of separate disciplines (e.g. hydrology, geology, topography, oceanography and ecology). Each discipline has developed descriptions and models for a number of properties that together represent the site description. The current methodology for developing the surface system description and the integration to ecosystem models is documented in a methodology strategy report SKB-R--03-06. The procedures and guidelines given in that report were followed in this report. Compared with version 1.1 of the surface system description SKB-R--04-25, this report presents considerable additional features, especially in the ecosystem description (Chapter 4) and in the description of the surface hydrology (Section 3.4). A first attempt has also been made to connect the flow of matter (carbon) between the different ecosystems into an overall ecosystem model at a landscape level. A summarised version of this report is also presented in SKB-R--05-08 together with geological-, hydrogeological-, transport properties-, thermal properties-, rock mechanics- and hydrogeochemical descriptions.

  8. Description of surface systems. Preliminary site description. Forsmark area Version 1.2

    International Nuclear Information System (INIS)

    Swedish Nuclear Fuel and Waste Management Co (SKB) started site investigations for a deep repository for spent nuclear fuel in 2002 at two different sites in Sweden, Forsmark and Oskarshamn. The investigations should provide necessary information for a license application aimed at starting underground exploration. For this reason, ecosystem data need to be interpreted and assessed into site descriptive models, which in turn are used for safety assessment studies and for environmental impact assessment. Descriptions of the surface system are also needed for further planning of the site investigations. This report describes the surface ecosystems of the Forsmark site (e.g. hydrology, Quaternary deposits, chemistry, vegetation, animals and the human land use). The ecosystem description is an integration of the site and its regional setting, covering the current state of the biosphere as well as the ongoing natural processes affecting the longterm development. Improving the descriptions is important during both the initial and the complete site investigation phase. Before starting of the initial phase in Forsmark, version 0 of the site descriptive model was developed. The results of the initial site investigation phase is compiled into a preliminary site description of Forsmark (version 1.2) in June 2005. This report provides the major input and background to the biosphere description, in the 1.2 version of the Forsmark site description. The basis for this interim version is quality-assured field data from the Forsmark sub area and regional area, available in the SKB SICADA, and GIS data bases as of July 31th 2004 as well as version 1.1 of the Site Descriptive Model. To achieve an ecosystem site description there is a need to develop discipline-specific models by interpreting and analysing primary data.

    2013-01-01

    Full Text Available Context: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. Aims: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. Settings and Design: Prospective descriptive study. Materials and Methods: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. Statistical Analysis Used: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. Results: Of the 570 patients undergoing laparoscopic surgery, 17 (3% had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI was the most frequent (n = 10, 1.8%, followed by port site bleeding (n = 4, 0.7%, omentum-related complications (n = 2; 0.35%, and port site metastasis (n = 1, 0.175%. Conclusions: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit.

    A totally semantic measure is presented which is able to calculate a similarity value between concept descriptions and also between concept description and individual or between individuals expressed in an expressive description logic. It is applicable on symbolic descriptions although it uses a numeric approach for the calculus. Considering that Description Logics stand as the theoretic framework for the ontological knowledge representation and reasoning, the proposed measure can be effectively used for agglomerative and divisional clustering task applied to the semantic web domain.

    2011-01-01

    Computer-aided Design (CAD), video games and other computer graphic related technology evolves substantial processing to geometric elements. A novel geometric computing method is proposed with the integration of descriptive geometry, math and computer algorithm. Firstly, geometric elements in general position are transformed to a special position in new coordinate system. Then a 3D problem is projected to new coordinate planes. Finally, according to 2D/3D correspondence principle in descriptive geometry, the solution is constructed computerized drawing process with ruler and compasses. In order to make this method a regular operation, a two-level pattern is established. Basic Layer is a set algebraic packaged function including about ten Primary Geometric Functions (PGF) and one projection transformation. In Application Layer, a proper coordinate is established and a sequence of PGFs is sought for to get the final results. Examples illustrate the advantages of our method on dimension reduction, regulatory and visual computing and robustness.

    The kinetic description of the hydrogen electrode reaction (HER) in the whole range of overpotentials (-0.2 < {eta} (V) < 0.40) is presented. The Volmer-Heyrovsky-Tafel mechanism was solved considering simultaneously the following items: (i) the diffusional contribution of the molecular hydrogen from and towards the electrode surface, (ii) the forward and backward reaction rates of each elementary step and (iii) a Frumkin type adsorption for the reaction intermediate. In order to verify the descriptive capability of the kinetic expressions derived, an experimental study of the HER was carried out on a rotating platinum disc electrode in acid solution. From the correlation of these results the elementary kinetic parameters were evaluated and several aspects related to the kinetic mechanism were discussed. Finally, the use of these kinetic expressions to interpret results obtained on microelectrodes is also analysed.

    1999-07-01

    Full Text Available A systematic methodology for microstructural description can help the task of obtaining the processing x microstructure x properties x performance relationships. There are, however, some difficulties in performing this task, which are related mainly to the following three factors: the complexity of the interactions between microstructural features; difficulties in evaluating geometric parameters of microstructural features; and difficulties in relating these geometric parameters to process variables. To solve some of these problems, it is proposed a methodology that embodies the following features: takes into account the different possible types of approaches for the microstructural description problem; includes concepts and tools of Total Quality Management; is supported on techniques of system analysis; and makes use of computer modeling and simulation and statistical design of experiments tools. The methodology was applied on evaluating some topological parameters during sintering process and its results were compared with available experimental data.

    2015-01-01

    The effective description of loop quantum cosmology (LQC) has proved to be a convenient platform to study phenomenological implications of the quantum bounce that resolves the classical big-bang singularity. Originally, this description was derived using Gaussian quantum states with small dispersions. In this paper we present a generalization to incorporate states with large dispersions. Specifically, we derive the \\emph{generalized} effective Friedmann and Raychaudhuri equations and propose a generalized effective Hamiltonian which are being used in an ongoing study of the phenomenological consequences of a broad class of quantum geometries. We also discuss an interesting interplay between the physics of states with larger dispersions in standard LQC, and of sharply peaked states in (hypothetical) LQC theories with larger area gap.

    This paper presents a functional language for the unambiguous description of digital circuits,a method and algorithms to obtain a standard-cell layout,and a comparative evaluation of the developed functional standard-cell placement technique.The presented placement scheme is different from traditional methods because the complete layout grometry is specified and constructed automatically from a functional description.The construction relies on a translation that combines the simplicity of standard-cells with the elegance of functional programming.An evaluation of the method introduced shows that the quality of the resulting placement is close to the results achieved with simulated annealing while the computation time is significantly less.Furthermore,the evaluation suggests to employ the functional placement method in conjunction with low-temperature simulated annealing for running-time reduction and improvedresults.

    CERN Document Server

    Valipour, Mehrdad

    2011-01-01

    In this paper, channel optimized distributed multiple description vector quantization (CDMD) schemes are presented for distributed source coding in symmetric and asymmetric settings. The CDMD encoder is designed using a deterministic annealing approach over noisy channels with packet loss. A minimum mean squared error asymmetric CDMD decoder is proposed for effective reconstruction of a source, utilizing the side information (SI) and its corresponding received descriptions. The proposed iterative symmetric CDMD decoder jointly reconstructs the symbols of multiple correlated sources. Two types of symmetric CDMD decoders, namely the estimated-SI and the soft-SI decoders, are presented which respectively exploit the reconstructed symbols and a posteriori probabilities of other sources as SI in iterations. In a multiple source CDMD setting, for reconstruction of a source, three methods are proposed to select another source as its SI during the decoding. The methods operate based on minimum physical distance (in a...

  10. Indeterminate direction relation model based on fuzzy description framework

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The indetermination of direction relation is a hot topic for fuzzy GIS researchers. The existing models only study the effects of indetermination of spatial objects,but ignore the uncertainty of direction reference framework. In this paper,first a for-malized representation model of indeterminate spatial objects is designed based on quadruple (x,y,A,μ),then a fuzzy direction reference framework is constructed by revising the cone method,in which the partitions of direction tiles are smooth and continuous,and two neighboring sections are overlapped in the transitional zones with fuzzy method. Grounded on these,a fuzzy description model for indeterminate direction relation is proposed in which the uncertainty of all three parts (source object,reference object and reference frame) is taken into account simultaneously. In the end,case studies are implemented to test the rationality and validity of the model.

  12. Generalized description of intermittency in turbulence via stochastic methods

    CERN Document Server

    Friedrich, J

    2016-01-01

    We present a generalized picture of intermittency in turbulence that is based on the theory of stochastic processes. To this end, we rely on the experimentally and numerically verified finding by R.~Friedrich and J.~Peinke [Phys. Rev. Lett. 78, 863 (1997)] that allows for an interpretation of the turbulent energy cascade as a Markov process of the velocity increments in scale. It is explicitly shown that all known phenomenological models of turbulence can be reproduced by the Kramers-Moyal expansion of the velocity increment probability density function that is associated to a Markov process. We compare the different sets of Kramers-Moyal coefficients of each phenomenology and deduce that an accurate description of intermittency should take into account an infinite number of coefficients. This is demonstrated in more detail for the case of Burgers turbulence that exhibits the strongest intermittency effects. Moreover, the influence of nonlocality on the Kramers-Moyal coefficients is investigated by direct num...

  13. Lockhart Clarke's contribution to the description of amyotrophic lateral sclerosis.

    Science.gov (United States)

    Turner, Martin R; Swash, Michael; Ebers, George C

    2010-11-01

    The definition of the clinicopathological entity of amyotrophic lateral sclerosis evolved over half a century. Although the definitive term amyotrophic lateral sclerosis that acknowledged both upper and lower motor neuron involvement was attributed to Jean-Martin Charcot in 1874, his initial case was published nearly a decade earlier; and it is accepted that, from at least the 1830s, several others (including Charles Bell, François-Amilcar Aran and Jean Cruveilhier) had already recognized a progressive lower motor neuron-only syndrome within a broader, clinically-defined group of disorders, termed progressive muscular atrophy. Although William Gowers first grouped the three phenotypes of amyotrophic lateral sclerosis, progressive muscular atrophy and progressive bulbar palsy together as part of the same syndrome, the term motor neuron disease, as an over-arching label, was not suggested until nearly a century later by W. Russell Brain. Augustus Jacob Lockhart Clarke (1817-80) is best known for his descriptions of spinal cord anatomy. However, in two detailed case reports from the 1860s, he carried out rigorous post-mortem neuropathological studies of what appear to be classical cases of amyotrophic lateral sclerosis. Furthermore, he recognized the additional involvement of the corticospinal tracts that distinguished this from progressive muscular atrophy. Several aspects of the exquisite clinical histories documented as part of both studies, one by Charles Bland Radcliffe, resonate with contemporary debates concerning the evolution of disease in amyotrophic lateral sclerosis. These 'past masters' still have much to teach us.

  14. Macroscopic Description for Networks of Spiking Neurons

    Montbrió, Ernest; Pazó, Diego; Roxin, Alex

    2015-04-01

    A major goal of neuroscience, statistical physics, and nonlinear dynamics is to understand how brain function arises from the collective dynamics of networks of spiking neurons. This challenge has been chiefly addressed through large-scale numerical simulations. Alternatively, researchers have formulated mean-field theories to gain insight into macroscopic states of large neuronal networks in terms of the collective firing activity of the neurons, or the firing rate. However, these theories have not succeeded in establishing an exact correspondence between the firing rate of the network and the underlying microscopic state of the spiking neurons. This has largely constrained the range of applicability of such macroscopic descriptions, particularly when trying to describe neuronal synchronization. Here, we provide the derivation of a set of exact macroscopic equations for a network of spiking neurons. Our results reveal that the spike generation mechanism of individual neurons introduces an effective coupling between two biophysically relevant macroscopic quantities, the firing rate and the mean membrane potential, which together govern the evolution of the neuronal network. The resulting equations exactly describe all possible macroscopic dynamical states of the network, including states of synchronous spiking activity. Finally, we show that the firing-rate description is related, via a conformal map, to a low-dimensional description in terms of the Kuramoto order parameter, called Ott-Antonsen theory. We anticipate that our results will be an important tool in investigating how large networks of spiking neurons self-organize in time to process and encode information in the brain.

  19. Horizons of description: Black holes and complementarity

    Science.gov (United States)

    Bokulich, Peter Joshua Martin

    Niels Bohr famously argued that a consistent understanding of quantum mechanics requires a new epistemic framework, which he named complementarity . This position asserts that even in the context of quantum theory, classical concepts must be used to understand and communicate measurement results. The apparent conflict between certain classical descriptions is avoided by recognizing that their application now crucially depends on the measurement context. Recently it has been argued that a new form of complementarity can provide a solution to the so-called information loss paradox. Stephen Hawking argues that the evolution of black holes cannot be described by standard unitary quantum evolution, because such evolution always preserves information, while the evaporation of a black hole will imply that any information that fell into it is irrevocably lost---hence a "paradox." Some researchers in quantum gravity have argued that this paradox can be resolved if one interprets certain seemingly incompatible descriptions of events around black holes as instead being complementary. In this dissertation I assess the extent to which this black hole complementarity can be undergirded by Bohr's account of the limitations of classical concepts. I begin by offering an interpretation of Bohr's complementarity and the role that it plays in his philosophy of quantum theory. After clarifying the nature of classical concepts, I offer an account of the limitations these concepts face, and argue that Bohr's appeal to disturbance is best understood as referring to these conceptual limits. Following preparatory chapters on issues in quantum field theory and black hole mechanics, I offer an analysis of the information loss paradox and various responses to it. I consider the three most prominent accounts of black hole complementarity and argue that they fail to offer sufficient justification for the proposed incompatibility between descriptions. The lesson that emerges from this

    2008-01-01

    Data integration is the issue of retrieving and combining data residing at distributed and heterogeneous sources,and of providing users with transparent access without being aware of the details of the sources.Data integration is a very important issue because it deals with data infrastructure issues of coordinated computing systems.Despite its importance,the following key challenges make data integration one of the longest standing problems around:1) how to solve the system heterogeneity;2) how to build a global model;3) how to process queries automatically and correctly;and 4) how to solve semantic heterogeneity. This paper presents an extended dynamic description logic language to describe systems with dynamic actions.By this language,a-universal and unified model for relational database systems and a model for data integration are presented.This paper presents a universal and unified description logic model for relational databases.The model is universal because any relational database system can be automatically transformed to the model;it is unified because it integrates three essential components of relational databases together:description logic knowledge bases modeling the relational data,atomic modalities modeling the atomic relational operations,and combined modalities modeling the combined relational operations-queries. Furthermore,a description logic model for data integration is proposed which contains four layers of ontologies.Based on the model,a solution for each key challenge is proposed:a universal model eliminates system heterogeneity;a novel global model including three ontologies is proposed with some important benefits;a query process mechanism is provided by which user queries can be decomposed to queries over the sources;and for solving the semantic heterogeneity,this paper provides a framework under which semantic relations can be expressed and inferred. In summary,this paper presents a dynamic knowledge base framework by an extended

    Full Text Available A quantum-mechanical description of the phase shifters, retarders, mirrors and beam splitters is given in the paper. The description is then applied on two types of states. On a coherent state, a classical-like state, and on a number state, hence the strict quantum state. The quantum description of a beam splitter can be found in the literature. However the description does not treat with the polarization concept. The paper is aimed to introduce quantum description of an arbitrary oriented retarder and give a description of a beam splitter which treats with the polarization.

  4. Dynamic behavior of micro-diaphragms and its characterized description

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Diaphragm structures with micron scale play a significant role in microtransducers and micro-nano devices, and the performance of these devices depends mainly on the dynamic behaviour of diaphragms. Micro-diaphragms are treated commonly as membranes and in some cases as plates or plates in tension (called TD plates for short), but they also show in many cases the behaviour of plates in tension and supported by air spring (called TDK plates for short). Therefore, it is necessary to perform systematic research on the dynamic behaviour of micro-diaphragms, and establish a characterized mathematical description. This paper focuses on the TDK plates since they possess universality, gives the corresponding basic equations, and then derives analytical solutions of TDK circular plates under clamped and simply supported boundary conditions. This paper also gives a 3D plot representation of characteristic curved surfaces, revealing the transition from the TDK and TD plate to the pure plate or pure membrane behaviour; and further uses the value φ to determine the property of diaphragms. Its two extreme cases, i.e. φ = 0 and φ = ∞ , correspond to pure plate or pure membrane, respectively. Thus, membrane, plate and TD plate can be treated as special cases of TDK plate. In addition, this paper reveals that the presence of air-spring not only enhances the restoring force of diaphragm such that increases its natural frequencies, but also results in the resonance of a dynamic system consisting of diaphragm and air-spring. These analytical and computational results are significant for the understanding of the operation mechanism of capacitive microtransducers and their optimized design.

    input. This forward channel also introduces random delays and dropouts. The feedback channel from the plant output to the controller is assumed noiseless. We show how to design MDs for packetized predicted control (PPC) in order to enhance the robustness. In the proposed scheme, a quantized control...... vector with future tentative control signals is transmitted to the plant at each discrete time instant. This control vector is then transformed into M redundant descriptions (packets) such that when receiving any 1≤J≤M packets, the current control signal as well as J−1 future control signals can...

    In this paper we construct a detailed map from pure and mixed half-BPS states of the D1-D5 system to half-BPS solutions of type IIB supergravity. Using this map, we can see how gravity arises through coarse graining microstates, and we can explicitly confirm the microscopic description of conical defect metrics, the M = 0 BTZ black hole and of small black rings. We find that the entropy associated to the natural geometric stretched horizon typically exceeds that of the mixed state from which the geometry was obtained.

  9. Cylinder light concentrator and absorber: theoretical description.

    Kildishev, Alexander V; Prokopeva, Ludmila J; Narimanov, Evgenii E

    2010-08-01

    We present a detailed theoretical description of a broadband omnidirectional light concentrator and absorber with cylinder geometry. The proposed optical "trap" captures nearly all the incident light within its geometric cross-section, leading to a broad range of possible applications--from solar energy harvesting to thermal light emitters and optoelectronic components. We have demonstrated that an approximate lamellar black-hole with a moderate number of homogeneous layers, while giving the desired ray-optical performance, can provide absorption efficiencies comparable to those of ideal devices with a smooth gradient in index.

    In the modern medical era, facial paralysis is linked with the name of Charles Bell. This disease, which is usually unilateral and is a peripheral facial palsy, causes facial muscle weakness in the affected side. Bell gave a complete description of the disease; but historically other physicians had described it several hundred years prior although it had been ignored for different reasons, such as the difficulty of the original text language. The first and the most famous of these physicians who described this disease was Mohammad Ibn Zakaryya Razi (Rhazes). In this article, we discuss his opinion.

  12. Forsmark - site descriptive model version 0

    International Nuclear Information System (INIS)

    During 2002, the Swedish Nuclear Fuel and Waste Management Company (SKB) is starting investigations at two potential sites for a deep repository in the Precambrian basement of the Fennoscandian Shield. The present report concerns one of those sites, Forsmark, which lies in the municipality of Oesthammar, on the east coast of Sweden, about 150 kilometres north of Stockholm. The site description should present all collected data and interpreted parameters of importance for the overall scientific understanding of the site, for the technical design and environmental impact assessment of the deep repository, and for the assessment of long-term safety. The site description will have two main components: a written synthesis of the site, summarising the current state of knowledge, as documented in the databases containing the primary data from the site investigations, and one or several site descriptive models, in which the collected information is interpreted and presented in a form which can be used in numerical models for rock engineering, environmental impact and long-term safety assessments. The site descriptive models are devised and stepwise updated as the site investigations proceed. The point of departure for this process is the regional site descriptive model, version 0, which is the subject of the present report. Version 0 is developed out of the information available at the start of the site investigation. This information, with the exception of data from tunnels and drill holes at the sites of the Forsmark nuclear reactors and the underground low-middle active radioactive waste storage facility, SFR, is mainly 2D in nature (surface data), and is general and regional, rather than site-specific, in content. For this reason, the Forsmark site descriptive model, version 0, as detailed in the present report, has been developed at a regional scale. It covers a rectangular area, 15 km in a southwest-northeast and 11 km in a northwest-southeast direction, around the

  13. Arrangement and Description of the CERN Archive

    2005-01-01

    This paper describes recent work on the arrangement and description of the CERN Archive. In order to improve access a shelf list was created and then adapted to become a Guide for public use. A functional arrangement was chosen for the Guide, in the hope that this would accommodate ongoing reorganisations and would grow with CERN. A re-evaluation of this approach was carried out 18 months later, and produced several improvements. It also raised a number of questions concerning the theoretical basis for some of the decisions taken about archival arrangement, and suggested ideas for future directions.

  14. Theoretical Description of the Fission Process

    Energy Technology Data Exchange (ETDEWEB)

    Witold Nazarewicz

    2003-07-01

    The main goals of the project can be summarized as follows: Development of effective energy functionals that are appropriate for the description of heavy nuclei. Our goal is to improve the existing energy density (Skyrme) functionals to develop a force that will be used in calculations of fission dynamics. Systematic self-consistent calculations of binding energies and fission barriers of actinide and trans-actinide nuclei using modern density functionals. This will be followed by calculations of spontaneous fission lifetimes and mass and charge divisions using dynamic adiabatic approaches based on the WKB approximation. Investigate novel microscopic (non-adiabatic) methods to study the fission process.

  15. Hamiltonian description of the ideal fluid

    Morrison, P.J.

    1994-01-01

    Fluid mechanics is examined from a Hamiltonian perspective. The Hamiltonian point of view provides a unifying framework; by understanding the Hamiltonian perspective, one knows in advance (within bounds) what answers to expect and what kinds of procedures can be performed. The material is organized into five lectures, on the following topics: rudiments of few-degree-of-freedom Hamiltonian systems illustrated by passive advection in two-dimensional fluids; functional differentiation, two action principles of mechanics, and the action principle and canonical Hamiltonian description of the ideal fluid; noncanonical Hamiltonian dynamics with examples; tutorial on Lie groups and algebras, reduction-realization, and Clebsch variables; and stability and Hamiltonian systems.

  3. Embedded multiple description coding of video.

    2006-10-01

    Real-time delivery of video over best-effort error-prone packet networks requires scalable erasure-resilient compression systems in order to 1) meet the users' requirements in terms of quality, resolution, and frame-rate; 2) dynamically adapt the rate to the available channel capacity; and 3) provide robustness to data losses, as retransmission is often impractical. Furthermore, the employed erasure-resilience mechanisms should be scalable in order to adapt the degree of resiliency against transmission errors to the varying channel conditions. Driven by these constraints, we propose in this paper a novel design for scalable erasure-resilient video coding that couples the compression efficiency of the open-loop architecture with the robustness provided by multiple description coding. In our approach, scalability and packet-erasure resilience are jointly provided via embedded multiple description scalar quantization. Furthermore, a novel channel-aware rate-allocation technique is proposed that allows for shaping on-the-fly the output bit rate and the degree of resiliency without resorting to channel coding. As a result, robustness to data losses is traded for better visual quality when transmission occurs over reliable channels, while erasure resilience is introduced when noisy links are involved. Numerical results clearly demonstrate the advantages of the proposed approach over equivalent codec instantiations employing 1) no erasure-resilience mechanisms, 2) erasure-resilience with nonscalable redundancy, or 3) data-partitioning principles.

  4. Initial rheological description of high performance concretes

    Directory of Open Access Journals (Sweden)

    Alessandra Lorenzetti de Castro

    2006-12-01

    Full Text Available Concrete is defined as a composite material and, in rheological terms, it can be understood as a concentrated suspension of solid particles (aggregates in a viscous liquid (cement paste. On a macroscopic scale, concrete flows as a liquid. It is known that the rheological behavior of the concrete is close to that of a Bingham fluid and two rheological parameters regarding its description are needed: yield stress and plastic viscosity. The aim of this paper is to present the initial rheological description of high performance concretes using the modified slump test. According to the results, an increase of yield stress was observed over time, while a slight variation in plastic viscosity was noticed. The incorporation of silica fume showed changes in the rheological properties of fresh concrete. The behavior of these materials also varied with the mixing procedure employed in their production. The addition of superplasticizer meant that there was a large reduction in the mixture's yield stress, while plastic viscosity remained practically constant.

In two directions of philology – Literature Studies and Linguistics – psychological insight is understood differently. That is why the authors take into account both definitions in order to create a complete picture.Based on consideration of the notion of psychological insight from the point of view of Literature Studies and Linguistics, the authors highlight its common philological criteria (soul and feelings of the character, description of the inner world of the character through the details, fragments of the text showing events, thoughts and motivates of the character; cognitive and pragma-linguistic features (supposition, influence upon the reader; methods and ways of its representation in the works of art (the author’s direct indication of the feelings in the character’s soul, inner details: inner monologue and author’s psychological narration, inner speech, memory images and imagination, description of dreams.

  7. Mathematical description of bacterial traveling pulses.

    Directory of Open Access Journals (Sweden)

    Jonathan Saragosti

    Full Text Available The Keller-Segel system has been widely proposed as a model for bacterial waves driven by chemotactic processes. Current experiments on Escherichia coli have shown the precise structure of traveling pulses. We present here an alternative mathematical description of traveling pulses at the macroscopic scale. This modeling task is complemented with numerical simulations in accordance with the experimental observations. Our model is derived from an accurate kinetic description of the mesoscopic run-and-tumble process performed by bacteria. This can account for recent experimental observations with E. coli. Qualitative agreements include the asymmetry of the pulse and transition in the collective behaviour (clustered motion versus dispersion. In addition, we can capture quantitatively the traveling speed of the pulse as well as its characteristic length. This work opens several experimental and theoretical perspectives since coefficients at the macroscopic level are derived from considerations at the cellular scale. For instance, the particular response of a single cell to chemical cues turns out to have a strong effect on collective motion. Furthermore, the bottom-up scaling allows us to perform preliminary mathematical analysis and write efficient numerical schemes. This model is intended as a predictive tool for the investigation of bacterial collective motion.

    A standard for the self-description of fusion plasma diagnostics will be required in the near future. The motivation is to maintain and organize the information on all the components of a laboratory experiment, from the hardware to the access security, to save time and money. Since there is no existing standard to organize this kind of information, every EU Association stores and organizes each experiment in different ways. This can lead to severe problems when the particular organization schema is poorly documented. Standardization is the key to solve these problems. From the commercial information on the diagnostic (component supplier; component price) to the hardware description (component specifications; drawings) to the operation of the equipment (finite state machines) through change control (who changed what and when) and internationalization (information at least in English and a local language). This problem will be met on the ITER project, for which a solution is essential. A strong candidate solution is the Extensible Markup Language (XML). In this paper, a review of the current status of XML related technologies will be presented.

  9. Preliminary description of the transportation operations systems

    International Nuclear Information System (INIS)

    This document presents a preliminary description of the transportation operations systems designed to ship spent fuel and high-level waste (HLW) from waste generator sites to authorized waste receiving facilities. It is an initial effort to define the operations system and identifies the activities and system components necessary to provide complete transportation capability. It is intended that this be a project level working document to facilitate dialog for further identification of system elements and functional requirements. This process will lead to issuance of a System Requirements and Description (SRD) document for the transportation operations systems and will identify detailed system functional requirements, performance criteria, and functional interfaces. The transportation system is quite complex and is influenced by a large number of external factors and interfaces. Some of these interfaces (such as the repository) are just now being developed. Others (such as utility-handling capabilities) are currently in existence and must be accommodated or modified. Additionally, the allocation of requirements is likewise both developing (with the repository) and somewhat fixed. 16 refs., 15 figs., 12 tabs

    2015-01-01

    The renormalized adiabatic PBE (rAPBE) method has recently been shown to comprise a significant improvement over the random phase approximation (RPA) for total energy calculations of simple solids and molecules. Here we consider the formation energies of 19 group I and II metal oxides and a few...... transition-metal oxides. The mean absolute error relative to experiments is 0.21 eV and 0.38 eV per oxygen atom for rAPBE and RPA, respectively, and thus the rAPBE method greatly improves the description of metal-oxygen bonds across a wide range of oxides. The failure of the RPA can be partly attributed...... to the lack of error cancellation between the correlation energy of the oxide on the one hand and the bulk metal and oxygen molecule on the other hand, which are all separately predicted much too negative by the RPA. We ascribe the improved performance of the rAPBE to its significantly better description...

    2010-01-01

    This volume discusses the basic geometric contents of an image and presents a tree data structure to handle those contents efficiently. The nodes of the tree are derived from connected components of level sets of the intensity, while the edges represent inclusion information. Grain filters, morphological operators simplifying these geometric contents, are analyzed and several applications to image comparison and registration, and to edge and corner detection, are presented. The mathematically inclined reader may be most interested in Chapters 2 to 6, which generalize the topological Morse description to continuous or semicontinuous functions, while mathematical morphologists may more closely consider grain filters in Chapter 3. Computer scientists will find algorithmic considerations in Chapters 6 and 7, the full justification of which may be found in Chapters 2 and 4 respectively. Lastly, all readers can learn more about the motivation for this work in the image processing applications presented in Chapter 8...

    This report provides a template for future safety reports on long-term safety in support of important decisions and permit applications in connection with the construction of a deep repository system. The template aims at providing a uniform structure for describing long-term safety, after the repository has been closed and sealed. The availability of such a structure will simplify both preparation and review of the safety reports, and make it possible to follow how safety assessments are influenced by the progressively more detailed body of data that emerges. A separate section containing `descriptive examples` has been appended to the template. This section illustrates what the different chapters of the template should contain. 279 refs.

  18. Aligning Sequences by Minimum Description Length

    Directory of Open Access Journals (Sweden)

    John S. Conery

    2008-01-01

    Full Text Available This paper presents a new information theoretic framework for aligning sequences in bioinformatics. A transmitter compresses a set of sequences by constructing a regular expression that describes the regions of similarity in the sequences. To retrieve the original set of sequences, a receiver generates all strings that match the expression. An alignment algorithm uses minimum description length to encode and explore alternative expressions; the expression with the shortest encoding provides the best overall alignment. When two substrings contain letters that are similar according to a substitution matrix, a code length function based on conditional probabilities defined by the matrix will encode the substrings with fewer bits. In one experiment, alignments produced with this new method were found to be comparable to alignments from CLUSTALW. A second experiment measured the accuracy of the new method on pairwise alignments of sequences from the BAliBASE alignment benchmark.

  19. Description of Concrete Durability Damage Process

    CHEN Yueshun; WEI Jun; ZHAO Xiaolong

    2006-01-01

    Based on the damage mechanics, the concrete damage grade of relative stable environment in measurable spatial is constructed in this paper, and the concrete damage evolving model and corresponding failure rule is constructed based on the damage grade fore-defined. Therefore, the concrete health status and the residual life-span can be assessed according to the measured damage grade. It is propitious to drive the development of concrete durability assessment and life-span forecast. Its feasibility of concrcte damage process description and health assessment is validated with the example in this paper, in which the damage state is described with the ultrasound velocity attenuation, and the freeze-thaw process is regarded as the concrete durability degradation influencing factor to reflect the concrete durability degradation process.

  20. Chiral Cosmological Models: Dark Sector Fields Description

    2014-01-01

    The present review is devoted to a Chiral Cosmological Model as the self-gravitating nonlinear sigma model with the potential of (self)interactions employed in cosmology. The chiral cosmological model has successive applications in descriptions of the inflationary epoch of the Universe evolution; the present accelerated expansion of the Universe also can be described by the chiral fields multiplet as the dark energy in wide sense. To be more illustrative we are often addressed to the two-component chiral cosmological model. Namely, the two-component chiral cosmological model describing the phantom field with interaction to a canonical scalar field is analyzed in details. New generalized model of quintom character is proposed and exact solutions are founded out. In the review we represented the perturbation theory for chiral cosmological model with the aim to describe the structure formation using the progress achieved in the inflation theory. It was shown that cosmological perturbations from chiral fields can...
