    Despite all of the medical advances, Babinski sign has proved reliable in precise localization of central nervous system dysfunction. It is well accepted that Babinski sign is indicative of dysfunction of fibers within the pyramidal tract. Joseph François Félix Babinski first described the clinical significance of the reflex in 1896. He showed that the extensor plantar response was indicative of pyramidal dysfunction and that it was absent in hysteria. He also illustrated that it was present in infancy and transiently appeared in epilepsy and strychnine poisoning. Babinski also pointed to the existence of "formes frustes" of his reflex and recognized its occasional absence in patients with other clinical signs of pyramidal lesions. The sign emerges when the dysfunction of the pyramidal tract involves the fibers that project on motoneurons of foot muscles and is mediated by extensor hallucis longus. Babinski sign may not be present acutely after transverse lesions of the spinal cord or acute brain lesions because of temporary inexcitability of spinal motoneurons.

    2002-03-01

    Besides Babinski's, Lhermitte's sign is likely the eponym mostly used in the neurological literature. We review here the history of this eponym as well as recent advances on its pathophysiology and treatment. Lhermitte's phenomenon is, on one hand, a symptom as it is spontaneously explained by patients, and, on the other hand, a sign as it may be triggered by flexion of the nape. Initially described after head and cervical spine trauma, firstly by Marie and then by Babinski, it was Jean Lhermitte who recognized on it an etiological specificity, namely, a demyelinating sign of cervical spinal posterior cords. He also made a pathophysiological interpretation of the phenomenon, namely, a stretching of posterior cords during flexion of the neck. All authors agree that this phenomenon is more common in multiple sclerosis, although it has been descibed in many other conditions. The history of how this sign was hatched, whose pathophysiology remains a mystery, is fascinating. And it is fascinating the fact that patients compare the phenomenon with a current, especially if we bear in mind that few people may have suffered an electrocution, mainly in that time when just a few ones could actually enjoy domestic electricity.

    sharp that they cause paper cuts. Stains. If you accidentally spill some food or drink on your clothes, make sure you attempt to remove it as soon as possible and preferably within the same lunar cycle. Some teachers seem to think they should be worn with pride like the stains on a chemistry teacher's white coat. This is a myth. Materials. For scientists continually teaching about the wonder of smart materials, physics teachers are remarkably conservative in their choice of materials for their clothes. Try to break out from the traditional corduroy and tweed and practise what you teach. It is not acceptable to wear the actual tie you wore at school, as this will be at least 20 years old, be rather frayed and will have your name sewn in the back by your mum.

    In this project, we have developed a sign language tutor that lets users learn isolated signs by watching recorded videos and by trying the same signs. The system records the user's video and analyses it. If the sign is recognized, both verbal and animated feedback is given to the user. The system is able to recognize complex signs that involve both hand gestures and head movements and expressions. Our performance tests yield a 99% recognition rate on signs involving only manual gestures and 85% recognition rate on signs that involve both manual and non manual components, such as head movement and facial expressions.

    While the field of semiotics has been active since it was started by Peirce, it appears like the last decade has been especially productive with a number of important new concepts being developed within the biosemiotics community. The novel concept of the Semiotic scaffold by Hoffmeyer......, and that misalignment between the two processes result in faulty sign interpretation and over-signification. Such faulty signs were forbidden in the sign classification system of Peirce, so I defined them as forbidden signs. Here I present an analysis of the forbidden sign categories with examples from Occult semiotics...... is an important addition that offers insight into the hardware requirements for bio-semiosis. As any type of semiosis must be dependent upon Semiotic scaffolds, I recently argued that the process of semiosis has to be divided into two separate processes of sign establishment and sign interpretation...

    2007-01-01

    The goal of this article is to present to the radiologist the different theories of the sign and their consequences for sign representation in computer systems. All the theories of the sign are presented, but the most relevant are highlighted in order to explain the great modeling systems currently in use (such as DICOM-SR or the UMLS). The constructivist approach of the notion of disease, the semiosis process, which starting from signs produces new signs, and the structuralist analysis of sign through language are emphasized. The purpose of this analysis is to end up with a consensual representation of the sign that can be understood by human beings and processed by machines. Such a representation, also known as an ontology, is based on a semantic organization of language, thus allowing medicine to become a truly scientific discipline. It aims at disambiguating the symbols given to machines, which will help us in our reasoning.

    After the successful 2015 data taking with Micromegas detectors, targeting solar axion search, and with an InGrid detector, targeting solar chameleon search, CAST has started on its new 2016-2018 program which has been presented to SPSC at the 119th meeting in October 2015. This program extends the physics goals of CAST towards the search for solar chameleons using a force sensor (KWISP) and towards the search for relic axions using a microwave cavity inserted into the CAST magnet (CAST-CAPP). The search for solar chameleons and other axion-like particles was continued with a significantly upgraded InGrid detector. The new experiments make use different elements of the unique CAST infrastructure (KWISP: Abrixas XRT and sun pointing capability of CAST, CAST-CAPP: high magnetic dipole field), while the InGrid detector exploits all of CAST´s features (Abrixas XRT, high magnetic dipole field, sun pointing). All three experiments within CAST have made significant progress in exploring these new approaches in 2016...

    Morrow, Jasper M; Reilly, Mary M

    2011-10-01

    Joseph Babinski (1857-1932), a French neurologist of Polish descent, was the first person to describe extension of the big toe following stimulation of the sole of the foot on 22 February 1896 (Babinski, 1896). He referred to the sign as 'phénomène des orteils' (toes phenomenon) but it is now usually referred to eponymously as the 'Babinski sign' or descriptively as the extensor plantar response.

    Zadrozny, W. [T.J. Watson Research Center, Yorktown Heights, NY (United States)

    1996-12-31

    We present a finite model of Peirce`s ten classes of signs. We briefly describe Peirce`s taxonomy of signs; we prove that any finite collection of signs can be extended to a finite algebra of signs in which all interpretants are themselves being interpreted; and we argue that Peirce`s ten classes of signs can be defined using constraints on algebras of signs. The paper opens the possibility of defining multimodal cognitive agents using Peirce`s classes of signs, and is a first step towards building a computational logic of signs based on Peirce`s taxonomies.

  8. Babinski and Babinski sign.

    Science.gov (United States)

    Bassetti, C

    1995-12-01

    Babinski's sign probably is the best known neurologic eponym, referring to dorsiflexion of the great toe with or without fanning of the other toes and withdrawal of the leg. This follows plantar stimulation in patients with pyramidal tract dysfunction. Although the plantar reflex already had been described, Babinski--a French neurologist of Polish descent and a pupil of Charcot--was the first to differentiate between a normal and pathologic response of the toes and recognize its clinical implication. Despite the continuing controversy over its pathophysiologic interpretation, the clinical utility of Babinski's sign remains unchanged almost 100 years after its description.

    Full Text Available The paper discusses ongoing research on the effects of a signing avatar's modeling/rendering features on the perception of sign language animation. It reports a recent study that aimed to determine whether a character's visual style has an effect on how signing animated characters are perceived by viewers. The stimuli of the study were two polygonal characters presenting two different visual styles: stylized and realistic. Each character signed four sentences. Forty-seven participants with experience in American Sign Language (ASL viewed the animated signing clips in random order via web survey. They (1 identified the signed sentences (if recognizable, (2 rated their legibility, and (3 rated the appeal of the signing avatar. Findings show that while character's visual style does not have an effect on subjects' perceived legibility of the signs and sign recognition, it has an effect on subjects' interest in the character. The stylized signing avatar was perceived as more appealing than the realistic one.

A wrong sign is defined as a sign on the regression coefficient opposite to the researcher's intuition and experience. Some possible causes for the wrong sign discussed in this paper are a small range of x's, leverage points, missing variables, multicollinearity, and computational error. Additionally, techniques for determining the cause of the wrong sign are given.

  20. Visual Signs of Ageing

    Directory of Open Access Journals (Sweden)

    Helle Rexbye

    2007-07-01

    Full Text Available Consumer culture has placed the ageing body in a dilemma of representation. Physical appearance has become increasingly important as a symbol of identity, and at the same time society idealizes youth. This study explores visual ageing empirically. By using photographs of older persons (70+ as starting point, it is explored how visual age is assessed and interpreted. It is shown that informants read age in a spread of stages and categories. Main age indicators are biological markers: skin, eyes, and hair colour, but supplemented by vigour, style, and grooming. Furthermore, in-depth interviews indicate that visual age is mainly interpreted into categories and moral regulations rooted in early modernity. Subsequently the question of a postmodern perspective of visual ageing is discussed in this article. The empirical findings in the study question a postmodern fluidity of visual signs – at least when the concern is signs of ageing.

    The climate is beginning to behave in unusual ways. The global temperature reached unprecedented highs in 2015 and 2016, which led climatologists to predict an enormous El Nino that would cure California's record drought. It did not happen the way they expected. That tells us just how unreliable temperature has become as an indicator of important aspects of climate change. The world needs to go beyond global temperature to a set of planetary vital signs. Politicians should not over focus policy on one indicator. They need to look at the balance of evidence. A coalition of scientists and policy makers should start to develop vital signs at once, since they should be ready at the entry into force of the Paris Agreement in 2020. But vital signs are only the beginning. The world needs to learn how to use the vast knowledge we will be acquiring about climate change and its impacts. Is it not time to use all the tools at hand- observations from space and ground networks; demographic, economic and societal measures; big data statistical techniques; and numerical models-to inform politicians, managers, and the public of the evolving risks of climate change at global, regional, and local scales? Should we not think in advance of an always-on social and information network that provides decision-ready knowledge to those who hold the responsibility to act, wherever they are, at times of their choosing?

  5. Sign language perception research for improving automatic sign language recognition

    ten Holt, Gineke A.; Arendsen, Jeroen; de Ridder, Huib; Koenderink-van Doorn, Andrea J.; Reinders, Marcel J. T.; Hendriks, Emile A.

    2009-02-01

    Current automatic sign language recognition (ASLR) seldom uses perceptual knowledge about the recognition of sign language. Using such knowledge can improve ASLR because it can give an indication which elements or phases of a sign are important for its meaning. Also, the current generation of data-driven ASLR methods has shortcomings which may not be solvable without the use of knowledge on human sign language processing. Handling variation in the precise execution of signs is an example of such shortcomings: data-driven methods (which include almost all current methods) have difficulty recognizing signs that deviate too much from the examples that were used to train the method. Insight into human sign processing is needed to solve these problems. Perceptual research on sign language can provide such insights. This paper discusses knowledge derived from a set of sign perception experiments, and the application of such knowledge in ASLR. Among the findings are the facts that not all phases and elements of a sign are equally informative, that defining the 'correct' form for a sign is not trivial, and that statistical ASLR methods do not necessarily arrive at sign representations that resemble those of human beings. Apparently, current ASLR methods are quite different from human observers: their method of learning gives them different sign definitions, they regard each moment and element of a sign as equally important and they employ a single definition of 'correct' for all circumstances. If the object is for an ASLR method to handle natural sign language, then the insights from sign perception research must be integrated into ASLR.

    The pyramidal signs in the lower extremity can be divided into three groups: (1) Babinski's group characterised by dorsoflexion of the great toe, (2) pyramidal signs marked by plantar flexion of the toes (e.g. Rossolimo's sign), and (3) synkinetic movements such as Strümpell's phenomenon. Puusepp's sign described by the Estonian neurologist and neurosurgeon Ludvig Puusepp belongs to none of these three groups. Its eliciting does not differ from that of Babinski's sign. The response, however, is different and consists of a tonic slow abduction of the little toe. We showed its relevance on the basis of clinical examination of six patients: four females aged 29, 50, 43 and 57 years and two males aged 42 and 49 years. The diagnoses were as follows: a new relapse of multiple sclerosis, a secondary progressive multiple sclerosis, a left middle cerebral artery stroke, a lumbago resulting in L3-L4 fusion surgery, an amyotrophic lateral sclerosis and a left intracerebral haemorrhage respectively. Puusepp's sign was the only elicitable pyramidal sign in all the patients but two. The 50-year-old female patient revealed on neurological examination Babinski's sign on the left side and Puusepp's sign on the right side. The testing of pyramidal signs in the 57-year-old woman displayed a bilateral Strümpell's sign and a left Puusepp's sign. These six cases showed that although rarely recognized in the clinical practice Puusepp's sign contributed to establishing the diagnosis of a central motor neuron involvement in the case of an absent Babinski's sign. Thus, its testing does not differ from that of Babinski's sign which requires only a little attention from the examiner, but provides an important piece of clinical information.

  15. How do signs organize in directed signed social networks?

    Guo, Long

    2016-01-01

    We introduce a reshuffled approach to empirical analyze signs' organization in real directed signed social networks of Epinions and Slashdots from the global viewpoint. In the reshuffled approach, each negative link has probability $p_{rs}$ to exchange its sign with another positive link chosen randomly. Through calculating the entropies of social status ($S_{in}$ and $S_{out}$) of and mimicking opinion formation of the majority-rule model on each reshuffled signed network, we find that $S_{in}$ and $S_{out}$ reach their own minimum values as well as the magnetization $|m^{*}|$ reaches its maximum value at $p_{rs}=0$. Namely, individuals share the homogeneous properties of social status and dynamic status in real directed signed social networks. Our present work provides some interesting tools and perspective to understand the signs' organization in signed social networks.

  16. [Reverse Chaddock sign].

    Tashiro, Kunio

    2011-08-01

    It is widely accepted that the Babinski reflex is the most well-known and important pathological reflex in clinical neurology. Among many other pathological reflexes that elicit an upgoing great toe, such as Chaddock, Oppenheim, Gordon, Schaefer, and Stransky, only the Chaddock reflex is said to be as sensitive as the Babinski reflex. The optimal receptive fields of the Babinski and Chaddock reflexes are the lateral plantar surface and the external inframalleolar area of the dorsum, respectively. It has been said that the Babinski reflex, obtained by stroking the sole, is by far the best and most reliable method of eliciting an upgoing great toe. However, the Chaddock reflex, the external malleolar sign, is also considered sensitive and reliable according to the literature and everyday neurological practice. The major problems in eliciting the Babinski reflex by stroking the lateral part of the sole are false positive or negative responses due to foot withdrawal, tonic foot response, or some equivocal movements. On the other hand, according to my clinical experience, the external inframalleolar area, which is the receptive field of the Chaddock reflex, is definitely suitable for eliciting the upgoing great toe. In fact, the newly proposed method to stimulate the dorsum of the foot from the medial to the lateral side, which I term the "reversed Chaddock method," is equally sensitive to demonstrate pyramidal tract involvement. With the "reversed Chaddock method", the receptive field of the Chaddock reflex may be postulated to be in the territory of the sural nerve, which could be supported by the better response obtained on stimulation of the postero-lateral calf than the anterior shin. With regard to the receptive fields of the Babinski and Chaddock reflexes, the first sacral dermatome (S1) is also considered a reflexogenous zone, but since the dermatome shows marked overlapping, the zones vary among individuals. As upgoing toe responses are consistently observed in

    2014-04-01

    Full Text Available A signed graph (or, $sigraph$ in short is a graph G in which each edge x carries a value $\\sigma(x \\in \\{-, +\\}$ called its sign. Given a sigraph S, the negation $\\eta(S$ of the sigraph S is a sigraph obtained from S by reversing the sign of every edge of S. Two sigraphs $S_{1}$ and $S_{2}$ on the same underlying graph are switching equivalent if it is possible to assign signs `+' (`plus' or `-' (`minus' to vertices of $S_{1}$ such that by reversing the sign of each of its edges that has received opposite signs at its ends, one obtains $S_{2}$. In this paper, we characterize sigraphs which are negation switching invariant and also see for what sigraphs, S and $\\eta (S$ are signed isomorphic.

  18. Translating Signs, Producing Subjects

    Directory of Open Access Journals (Sweden)

    Brett Neilson

    2009-08-01

    Full Text Available This paper moves between two streets: Liverpool Road in the Sydney suburb of Ashfield and Via Sarpi in the Italian city of Milan. What connects these streets is that both have become important sites for businesses in the Chinese diaspora. Moreover, both are streets on which locals have expressed desires for Chinese signs to be translated into the national lingua franca. The paper argues that the cultural politics inherent in this demand for translation cannot be fully understood in the context of national debates about diversity and integration. It is also necessary to consider the emergence of the official Chinese Putonghua as global language, which competes with English but also colonizes dialects and minority languages. In the case of these dual language signs, the space between languages can neither be reduced to a contact zone of minority and majority cultures nor celebrated as a ‘third space’ where the power relations implied by such differences are subverted. At stake is rather a space characterised by what Naoki Sakai calls the schema of co-figuration, which allows the representation of translation as the passage between two equivalents that resemble each other and thus makes possible their determination as conceptually different and comparable. Drawing on arguments about translation and citizenship, the paper critically interrogates the ethos of interchangeability implied by this regime of translation. A closing argument is made for a vision of the common that implies neither civilisational harmony nor the translation of all values into a general equivalent. Primary sources include government reports, internet texts and media stories. These are analyzed using techniques of discourse analysis and interpreted with the help of secondary literature concerning globalisation, language and migration. The disciplinary matrix cuts and mixes between cultural studies, translation studies, citizenship studies, globalization studies and

  19. Rigler’s sign and the football sign

    Directory of Open Access Journals (Sweden)

    Sheetal Daya

    2012-12-01

    Full Text Available Rigler’s sign was first described in 1941 by L G Rigler as a new radiological sign for recognising free air in the peritoneal cavity on supine radiograph. The presence of pneumoperitoneum allows free intraperitoneal air to be contrasted with intraluminal gas, accentuating the wall of gas-containing viscera. It is observed in infants and very ill patients where only limited radiographs of the abdomen are possible. The football sign was first described by R E Miller in the 1960s. Seen on supine abdominal radiographs, this describes an oval radiolucency resembling an American football. It is important for the radiologist to recognise the supporting signs of pneumoperitoneum, such as Rigler’s sign and the football sign, on supine abdominal radiographs, especially in neonates and infants, where erect chest/abdominal radiographs are not always possible.

    Following groundbreaking work by linguists and cognitive scientists over the past thirty years, it is now generally accepted that sign languages of the deaf, such as ASL (American Sign Language) or BSL (British Sign Language), are structured and processed in a similar manner to spoken languages. The one striking difference is that they operate in a wholly non-auditory, visuospatial medium. How does the medium impact on language processing itself?

The approach is based on the latest computer vision methods for object detection, and on powerful methods for multiclass classification. The challenge was to robustly detect a set of different sign classes in real time, and to classify each detected sign into a large, extensible set of classes. To address this challenge, several state-of-the-art methods were developed that can be used for different recognition problems. Following an introduction to the problems of traffic sign detection and categoriza

    2010-01-01

    As we began working on the Danish Sign Language (DTS) Dictionary, we soon realised the truth in the statement that a lexicographer has to deal with problems within almost any linguistic discipline. Most of these problems come down to establishing simple rules, rules that can easily be applied every...... time you encounter a specific problem while describing a sign, and that enables the lexicographer to consistently answer questions like "what is the base form of this sign?", "how many meanings does this sign have?", "are these two forms two different meanings of the same polysemous sign...... – or are they homonyms?" and so on. Very often such questions demand further research and can't be answered sufficiently through a simple standard formula. Therefore lexicographic work often seems like an endless series of compromises. Another source of compromise arises when you set out to decide which information...

  8. Sign Inference for Dynamic Signed Networks via Dictionary Learning

    Directory of Open Access Journals (Sweden)

    Yi Cen

    2013-01-01

    Full Text Available Mobile online social network (mOSN is a burgeoning research area. However, most existing works referring to mOSNs deal with static network structures and simply encode whether relationships among entities exist or not. In contrast, relationships in signed mOSNs can be positive or negative and may be changed with time and locations. Applying certain global characteristics of social balance, in this paper, we aim to infer the unknown relationships in dynamic signed mOSNs and formulate this sign inference problem as a low-rank matrix estimation problem. Specifically, motivated by the Singular Value Thresholding (SVT algorithm, a compact dictionary is selected from the observed dataset. Based on this compact dictionary, the relationships in the dynamic signed mOSNs are estimated via solving the formulated problem. Furthermore, the estimation accuracy is improved by employing a dictionary self-updating mechanism.

  9. Sign order in Slovenian Sign Language locative constructions

    Directory of Open Access Journals (Sweden)

    Matic Pavlič

    2016-12-01

    Full Text Available In both sign and spoken languages, locative relations tend to be encoded within constructions that display the non-basic word/sign order. In addition, in such an environment, sign languages habitually use a distinct predicate type – a classifier predicate – which may independently affect the order of constituents in the sentence. In this paper, I present Slovenian Sign Language (SZJ locative constructions, in which (i the argument that enables spatial anchoring (“ground” precedes both the argument that requires spatial anchoring (“figure” and the predicate. At the same time, (ii the relative order of the figure with respect to the predicate depends on the type of predicate employed: a non-classifier predicate precedes the figure, while a classifier predicate only comes after the figure.

    2015-07-01

    Full Text Available The work of Ferdinand de Saussure was massively revisited, in 2013, the year of the centenary of the death of the Genevian Master. In fact, his linguistic production has always been the object of several studies since the publication of Course in General Linguistics, in 1916. This article brings to light the considerations of renowned linguists on the Saussurean work and its links with Discourse Analysis (DA, considering the notions of language sign and discourse sign. Among the various branches of DA, it is made an option herein for the Semiolinguistic conception of discourse, based on the work of Patrick Charaudeau, with emphasis on the concept of contract of communication. With the support of such theoretical support, media texts, verbal and non-verbal, will be analyzed in order to highlight the importance of linguistic signs – language and discourse signs – in the construction of meaning in such text genre.

    2007-01-01

    Neurological signs and symptoms are very important to establish a correct neurological diagnosis. We present here a Colombian female patient, 60 years-old, who had ischaemic stroke in the left cerebral media artery. It produced right hemiplegia, motor aphasia, "central" facial palsy and atrophy of right platysma muscle. This latter finding, described originally by Joseph Babinski as "The Babinski Sign" was observed only two years and seven months after the ictus even when she had, previously, been evaluated by several neurologists. The underdiagnosis of clinical signs like the one described here may lead to erroneous diagnosis that will, ultimately, affect neurorehabilitation measures.

    Neurologists have been analyzing the clinical behaviors that occur during seizures for many years. Several ictal behaviors have been defined in temporal lobe epilepsy (TLE). Ictal behaviors are especially important in the evaluation of epilepsy surgery candidates. We propose a new lateralizing sign in TLE originating from the nondominant hemisphere-the "hush" sign. Our patients were 30- and 21-year old women (Cases 1 and 2, respectively). Their epileptogenic foci were localized to the right mesial temporal region after noninvasive presurgical investigations. Case 1 had no cranial MRI abnormality, whereas cranial MRI revealed right hippocampal atrophy in Case 2. These women repeatedly moved their right index fingers to their mouth while puckering their lips during complex partial seizures. We have named this ictal behavior the "hush" sign. Anterior temporal lobectomy with amygdalohippocampectomy was performed in both patients, and pathological examinations revealed hippocampal sclerosis. The "hush" sign no longer occurred after seizures were controlled. They were seizure free as of 30 and 31 months of follow-up, respectively. We believe that the "hush" sign may be supportive of a diagnosis of TLE originating from the nondominant hemisphere. This sign may occur as a result of ictal activation of a specific brain region in this hemisphere.

    Leskovec, Jure; Kleinberg, Jon

    2010-01-01

    Relations between users on social media sites often reflect a mixture of positive (friendly) and negative (antagonistic) interactions. In contrast to the bulk of research on social networks that has focused almost exclusively on positive interpretations of links between people, we study how the interplay between positive and negative relationships affects the structure of on-line social networks. We connect our analyses to theories of signed networks from social psychology. We find that the classical theory of structural balance tends to capture certain common patterns of interaction, but that it is also at odds with some of the fundamental phenomena we observe --- particularly related to the evolving, directed nature of these on-line networks. We then develop an alternate theory of status that better explains the observed edge signs and provides insights into the underlying social mechanisms. Our work provides one of the first large-scale evaluations of theories of signed networks using on-line datasets, as ...

    Full Text Available Nowadays exponential advancement in reversible comp utation has lead to better fabrication and integration process. It has become very popular ove r the last few years since reversible logic circuit s dramatically reduce energy loss. It consumes less p ower by recovering bit loss from its unique input-o utput mapping. This paper presents two new gates called RC-I and RC-II to design an n-bit signed binary comparator where simulation results show that the p roposed circuit works correctly and gives significa ntly better performance than the existing counterparts. An algorithm has been presented in this paper for constructing an optimized reversible n-bit signed c omparator circuit. Moreover some lower bounds have been proposed on the quantum cost, the numbers of g ates used and the number of garbage outputs generated for designing a low cost reversible sign ed comparator. The comparative study shows that the proposed design exhibits superior performance consi dering all the efficiency parameters of reversible logic design which includes number of gates used, quantum cost, garbage output and constant inputs. This proposed design has certainly outperformed all the other existing approaches.

  19. Cooperative Sign Language Tutoring: A Multiagent Approach

    Science.gov (United States)

    Yıldırım, Ilker; Aran, Oya; Yolum, Pınar; Akarun, Lale

    Sign languages can be learned effectively only with frequent feedback from an expert in the field. The expert needs to watch a performed sign, and decide whether the sign has been performed well based on his/her previous knowledge about the sign. The expert's role can be imitated by an automatic system, which uses a training set as its knowledge base to train a classifier that can decide whether the performed sign is correct. However, when the system does not have enough previous knowledge about a given sign, the decision will not be accurate. Accordingly, we propose a multiagent architecture in which agents cooperate with each other to decide on the correct classification of performed signs. We apply different cooperation strategies and test their performances in varying environments. Further, through analysis of the multiagent system, we can discover inherent properties of sign languages, such as the existence of dialects.

  2. Sign (di)Lemma for Dimension Shifting

    Indian Academy of Sciences (India)

    2009-04-01

    There is a surprising occurrence of some minus signs in the isomorphisms produced in the well-known technique of dimension shifting in calculating derived functors in homological algebra. We explicitly determine these signs. Getting these signs right is important in order to avoid basic contradictions. We illustrate the result – which we call as the sign lemma for dimension shifting – by some de Rham cohomology and Chern class considerations for compact Riemann surfaces.

  3. Signed Young Modules and Simple Specht Modules

    2015-01-01

    By a result of Hemmer, every simple Specht module of a finite symmetric group over a field of odd characteristic is a signed Young module. While Specht modules are parametrized by partitions, indecomposable signed Young modules are parametrized by certain pairs of partitions. The main result of this article establishes the signed Young module labels of simple Specht modules. Along the way we prove a number of results concerning indecomposable signed Young modules that are of independent inter...

    OpenAIRE

    2005-01-01

    Recently Donkin defined signed Young modules as a simultaneous generalization of Young and twisted Young modules for the symmetric group. We show that in odd characteristic, if a Specht module $S^\\lambda$ is irreducible, then $S^\\lambda$ is a signed Young module. Thus the set of irreducible Specht modules coincides with the set of irreducible signed Young modules. This provides evidence for our conjecture that the signed Young modules are precisely the class of indecomposable self-dual module...

    2014-10-01

    Idiopathic immune myopathies (IIM) are an heterogeneous group of autoimmune muscle disorders characterized by progressive muscle involvement. Dermatomyositis (DM) is the most common form of IIM. It is a multisystem disorder characterized by symmetric proximal, extensor, inflammatory myopathy, vascular involvement and a characteristic cutaneous eruption. Six types of DM have been identified: idiopathic, juvenile (JDM), cancer-related other autoimmune diseases-related, iatrogenic DM and amyopathic DM. Cutaneous manifestations of DM are the most important aspect of this disease and can precede from several months to years muscle or systemic involvement. Three groups of signs have been described: pathognomonic, highly characteristic and compatible. Although differences exist among the different clinical presentation of skin lesions, they share common histological findings including the presence of interface dermatitis with epidermal atrophy, basement membrane degeneration, vacuolar alteration of basal keratinocytes, and dermal changes consisting of interstitial mucin deposition and a sparse lymphocytic infiltrate. DM is a serious disease; the correct evaluation of any skin lesion suggesting an early diagnosis is of utmost importance. Skin signs may, also, represent a marker of treatment efficacy even though systemic symptoms worsening may not always be followed by more severe skin lesions.

    2003-12-01

    The comprehension of safety signs for construction workers was compared among existing and improved designs. Safety signs considered were existing signs, existing signs improved by adding text, existing signs improved by adding/changing pictorials, and existing signs improved by adding/changing pictorials and text. Three hundred and eighty-four construction workers were randomized for assignments into four groups. They were working on nine constructions work sites randomly selected from work sites located in Bangkok, Thailand. The number of workers in each work site was calculated for the proportion of the sample size and then they were randomized so that equal numbers of workers were included in the four groups. The four types of safety signs and an interview form were used to test their comprehension of safety signs. For data analysis, percentages, means, standard deviations, the chi-square test, the one-way ANOVA and LSD tests were applied. The results showed that the mean comprehension scores of the existing signs improved by adding text, the existing signs improved by adding/changing pictorials, and the existing signs improved by adding/changing pictorials and text were significantly higher than those of the existing signs. In addition, the mean comprehension scores of the existing signs improved by adding text and the existing signs improved by adding/changing pictorials and text were significantly higher than those of the existing signs improved by adding/changing pictorials. The highest mean comprehension score of safety signs for the construction workers was found in the existing signs improved by adding/changing pictorials and text. These results indicated that for construction workers, the comprehension of safety signs with pictorials and explanatory text was better than that of the existing signs.

  7. A tour in sign language

    In early May, CERN welcomed a group of deaf children for a tour of Microcosm and a Fun with Physics demonstration.   On 4 May, around ten children from the Centre pour enfants sourds de Montbrillant (Montbrillant Centre for Deaf Children), a public school funded by the Office médico-pédagogique du canton de Genève, took a guided tour of the Microcosm exhibition and were treated to a Fun with Physics demonstration. The tour guides’ explanations were interpreted into sign language in real time by a professional interpreter who accompanied the children, and the pace and content were adapted to maximise the interaction with the children. This visit demonstrates CERN’s commitment to remaining as widely accessible as possible. To this end, most of CERN’s visit sites offer reduced-mobility access. In the past few months, CERN has also welcomed children suffering from xeroderma pigmentosum (a genetic disorder causing extreme sensiti...

  8. Epidemic spreading on evolving signed networks

    CERN Document Server

    Saeedian, M; Jafari, G R; Kertesz, J

    2016-01-01

    Most studies of disease spreading consider the underlying social network as obtained without the contagion, though epidemic influences peoples willingness to contact others: A friendly contact may be turned to unfriendly to avoid infection. We study the susceptible-infected (SI) disease spreading model on signed networks, in which each edge is associated with a positive or negative sign representing the friendly or unfriendly relation between its end nodes. In a signed network, according to Heiders theory, edge signs evolve such that finally a state of structural balance is achieved, corresponding to no frustration in physics terms. However, the danger of infection affects the evolution of its edge signs. To describe the coupled problem of the sign evolution and disease spreading, we generalize the notion of structural balance by taking into account the state of the nodes. We introduce an energy function and carry out Monte-Carlo simulations on complete networks to test the energy landscape, where we find loc...

  9. INERTIA SETS OF SYMMETRIC SIGN PATTERN MATRICES

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A sign pattern matrix is a matrixwhose entries are from the set {+ ,- ,0}. The symmetric sign pattern matrices that require unique inertia have recently been characterized. The purpose of this paper is to more generally investigate the inertia sets of symmetric sign pattern matrices. In particular, nonnegative fri-diagonal sign patterns and the square sign pattern with all + entries are examined. An algorithm is given for generating nonnegative real symmetric Toeplitz matrices with zero diagonal of orders n≥3 which have exactly two negative eigenvalues. The inertia set of the square pattern with all + off-diagonal entries and zero diagonal entries is then analyzed. The types of inertias which can be in the inertia set of any sign pattern are also obtained in the paper. Specifically, certain compatibility and consecutiveness properties are established.

  10. Aphasia in a user of British Sign Language: Dissociation between sign and gesture.

    Science.gov (United States)

    Marshall, Jane; Atkinson, Jo; Smulovitch, Elaine; Thacker, Alice; Woll, Bencie

    2004-07-01

    This paper reports a single case investigation of "Charles", a Deaf man with sign language aphasia following a left CVA. Anomia, or a deficit in sign retrieval, was a prominent feature of his aphasia, and this showed many of the well-documented characteristics of speech anomia. For example, sign retrieval was sensitive to familiarity, it could be cued, and there were both semantic and phonological errors. Like a previous case in the literature (Corina, Poizner, Bellugi, Feinberg, Dowd, & O'Grady-Batch, 1992), Charles demonstrated a striking dissociation between sign and gesture, since his gesture production was relatively intact. This dissociation was impervious to the iconicity of signs. So, Charles' sign production showed no effect of iconicity, and gesture production was superior to sign production even when the forms of the signs and gestures were similar. The implications of these findings for models of sign and gesture production are discussed.

    The CT halo sign has been described as the CT finding of a low-attenuation zone surrounding a pulmonary nodule. It is an early clue to the diagnosis of invasive pulmonary aspergillosis. We describe a case of CT halo sign associated with a pulmonary tuberculoma. Therefore, we think that a diagnosis other than invasive pulmonary aspergillosis should be considered in the presence of the CT halo sign in immunocompetent patients.

This endeavour is yet another approach to accomplish interpretation of human hand gestures. The first step of this work is background subtraction which achieved by the Euclidean distance threshold method. Thinning algorithm is then applied to obtain a thinned image of the human hand for further analysis. The different feature points which include terminating points and curved edges are extracted for the recognition of the different signs. The input for the project is taken from video data of a human hand gesturing all the signs of the American Sign Language.

  16. Objects in Films: analyzing signs

    Directory of Open Access Journals (Sweden)

    GAMBARATO, Renira Rampazzo

    2009-12-01

    Full Text Available The focus of this essay is the analysis of daily objects as signs in films. Objects from everyday life acquire several functions in films: they can be solely used as scene objects or to support a particular film style. Other objects are specially chosen to translate a character’s interior state of mind or the filmmaker’s aesthetical or ethical commitment to narrative concepts. In order to understand such functions and commitments, we developed a methodology for film analysis which focuses on the objects. Object interpretation, as the starting point of film analysis, is not a new approach. For instance, French film critic André Bazin proposed that use of object interpretation in the 1950s. Similarly, German film theorist Siegfried Kracauer stated it in the 1960s. However, there is currently no existing analytical model to use when engaging in object interpretation in film. This methodology searches for the most representative objects in films which involves both quantitative and qualitative analysis; we consider the number of times each object appears in a film (quantitative analysis as well as the context of their appearance, i.e. the type of shot used and how that creates either a larger or smaller relevance and/or expressiveness (qualitative analysis. In addition to the criteria of relevance and expressiveness, we also analyze the functionality of an object by exploring details and specifying the role various objects play in films. This research was developed at Concordia University, Montreal, Canada and was supported by the Foreign Affairs and International Trade, Canada (DFAIT.

  10. Signs, dispositions, and semiotic scaffolding.

    Science.gov (United States)

    Fernández, Eliseo

    2015-12-01

    In theoretical work we distinguish living beings from inanimate objects on the basis of some paramount attributes, such as agency and autonomy. These abstract features are not directly accessible to our scrutiny, but we surmise their nature through observation of the purpose-oriented behavior of organisms. I intend to show that organismal purposefulness springs from the intrinsic, constitutive kind of finality that is the hallmark of all semiotic transactions. To this aim I develop a dispositionalist account of organismal causation based on a distinction between two kinds of causal dispositions: fixed (efficient) dispositions and traveling dispositions. Fixed dispositions are rigidly attached to physical structures and processes; these are the dispositions regularly invoked in current discussions of causal explanation. Traveling dispositions are able to move freely from one location to another by becoming embodied into suitable supporting media. I introduce these notions to articulate a view of semiosis I deem best suited to the life sciences, and contend that sign tokens are vehicles of traveling dispositions. This account places the origin of purposive behavior at the interaction of physical and semiotic causation. To properly motivate the discussion I briefly review some recent developments in the philosophy of science concerning various forms of causation invoked by scientists across disciplines to frame explanations and make predictions. The ensuing discussion gives particular prominence to mechanistic (as distinct from mechanicist) explanatory accounts of biological phenomena. This review is followed by a brief characterization of a "nomological machine," a comprehensive schema introduced and developed by Nancy Cartwright with the goal of explaining causal mechanisms in a general setting. By capitalizing on this model's heuristic virtues I seek to formulate a compelling view of the interactions between physical and semiotic causation at play in semiotic

  11. Eigen-Gradients for Traffic Sign Recognition

    2013-01-01

    Full Text Available Traffic sign detection and recognition systems include a variety of applications like autonomous driving, road sign inventory, and driver support systems. Machine learning algorithms provide useful tools for traffic sign identification tasks. However, classification algorithms depend on the preprocessing stage to obtain high accuracy rates. This paper proposes a road sign characterization method based on oriented gradient maps and the Karhunen-Loeve transform in order to improve classification performance. Dimensionality reduction may be important for portable applications on resource constrained devices like FPGAs; therefore, our approach focuses on achieving a good classification accuracy by using a reduced amount of attributes compared to some state-of-the-art methods. The proposed method was tested using German Traffic Sign Recognition Benchmark, reaching a dimensionality reduction of 99.3% and a classification accuracy of 95.9% with a Multi-Layer Perceptron.

    Full Text Available This paper introduces an Arabic Alphabet and Numbers Sign Language Recognition (ArANSLR. It facilitates the communication between the deaf and normal people by recognizing the alphabet and numbers signs of Arabic sign language to text or speech. To achieve this target, the system able to visually recognize gestures from hand image input. The proposed algorithm uses hand geometry and the different shape of a hand in each sign for classifying letters shape by using Hidden Markov Model (HMM. Experiments on real-world datasets showed that the proposed algorithm for Arabic alphabet and numbers sign language recognition is suitability and reliability compared with other competitive algorithms. The experiment results show that the increasing of the gesture recognition rate depends on the increasing of the number of zones by dividing the rectangle surrounding the hand.

  13. Road Signs for UV-Completion

    Dvali, Gia; Gomez, Cesar

    2012-01-01

    We confront the concepts of Wilsonian UV-completion versus self-completion by Classicalization in theories with derivatively-coupled scalars. We observe that the information about the UV-completion road is encoded in the sign of the derivative terms. We note that the sign of the derivative couplings for which there is no consistent Wilsonian UV-completion is the one that allows for consistent classicalons. This is an indication that for such a sign the vertex must be treated as fundamental and the theory self-protects against potential inconsistencies, such as superluminality, via self-completion by classicalization. Applying this reasoning to the UV-completion of the Standard Model, we see that the information about the Higgs versus classicalization is encoded in the sign of the scattering amplitude of longitudinal W-bosons. Negative sign excludes Higgs or any other weakly-coupled Wilsonian physics.

    We propose a communication library, ShareVitalSigns, for the standardized exchange of vital sign information between health applications running on mobile platforms. The library allows an application to request one or multiple vital signs from independent measurement applications on the Android OS. Compatible measurement applications are automatically detected and can be launched from within the requesting application, simplifying the work flow for the user and reducing typing errors. Data is shared between applications using intents, a passive data structure available on Android OS. The library is accompanied by a test application which serves as a demonstrator. The secure exchange of vital sign information using a standardized library like ShareVitalSigns will facilitate the integration of measurement applications into diagnostic and other high level health monitoring applications and reduce errors due to manual entry of information.

  1. Sign variation, the Grassmannian, and total positivity

    CERN Document Server

    Karp, Steven N

    2016-01-01

    The totally nonnegative Grassmannian is the set of k-dimensional subspaces V of R^n whose nonzero Pluecker coordinates all have the same sign. Gantmakher and Krein (1950) and Schoenberg and Whitney (1951) independently showed that V is totally nonnegative iff every vector in V, when viewed as a sequence of n numbers and ignoring any zeros, changes sign at most k-1 times. We generalize this result from the totally nonnegative Grassmannian to the entire Grassmannian, showing that if V is generic (i.e. has no zero Pluecker coordinates), then the vectors in V change sign at most m times iff certain sequences of Pluecker coordinates of V change sign at most m-k+1 times. We also give an algorithm which, given a non-generic V whose vectors change sign at most m times, perturbs V into a generic subspace whose vectors also change sign at most m times. We deduce that among all V whose vectors change sign at most m times, the generic subspaces are dense. These results generalize to oriented matroids. As an application o...

  2. The Babinski sign--a reappraisal.

    Kumar, S P; Ramasubramanian, D

    2000-12-01

    In 1896, Joseph Babinski, a French neurologist, first described the best known neurologic eponym 'the Babinski sign'. This sign is characterised by dorsiflexion of the big toe and recruitment of the extensor hallucis longus muscle, on stimulating the sole of the foot. He has emphasised from the outset, the intimate relationship between this sign and the shortening movement in other leg muscles, which form the flexion synergy of the lower limb. The Babinski sign is not a new reflex, rather it is released as a result of breakdown of the harmonious integration of the flexion and extension components of the normal defence reflex mechanism, due to pyramidal tract dysfunction. A pathological Babinski sign should be clearly distinguished from upgoing toes that may not always be a part of the flexion synergy. This article reviews the Babinski sign in detail, focusing on the historical perspectives, role of pyramidal tract dysfunction and art of elicitation and interpretation. The significance of assessing this phenomenon in the entire leg, and the clinical clues that will help to dispel the myths regarding the Babinski sign, have been emphasised.

  4. VARIATIONS IN TACTILE SIGNING – THE CASE OF ONE-HANDED SIGNING

    Directory of Open Access Journals (Sweden)

    Johanna Mesch

    2011-01-01

    Full Text Available Tactile sign language is a variety of a national sign language. Tactile signing among persons with deafblindness also includes some minor variations. Early analyses of tactile Swedish Sign Language (e.g. Mesch 1998, 2001 show how interactants use both their hands in tactile communication in two different positions: dialogue position and monologue position. This paper examines the signing variations that partially or functionally blind signers encounter when using one hand to communicate with each other in a conversation dyad in what is one of the most advanced types of sign language communication. In tactile one-handed signing, the signer uses her right hand both for producing and receiving signs, while the addressee uses her left hand not only for receiving but also for producing signs after turn-taking, even though it is the non-dominant hand and, therefore, is not normally used to produce one-handed signs. In this study, conversation analysis was conducted on the discourse of four groups. The results show that some variations depend on the linguistic background of individuals and their everyday communication. A comparative study of a two-handed and a one-handed system is then presented, focusing on issues of simplicity, flexibility, turn-taking, and feedback. Some results showing changes in the sign structures of both communication types are also presented.

  5. How to estimate the signs' configuration in the directed signed social networks?

    Science.gov (United States)

    Guo, Long; Gao, Fujuan; Jiang, Jian

    2017-02-01

    Inspired by the ensemble theory in statistical mechanics, we introduce a reshuffling approach to empirical analyze signs' configuration in the directed signed social networks of Epinions and Slashdots. In our reshuffling approach, each negative link has the reshuffling probability prs to exchange its sign with another positive link chosen randomly. Many reshuffled networks with different signs' configuration are built under different prss. For each reshuffled network, the entropies of the self social status are calculated and the opinion formation of the majority-rule model is analyzed. We find that Souts reach their own minimum values and the order parameter |m* | reaches its maximum value in the networks of Epinions and Slashdots without the reshuffling operation. Namely, individuals share the homogeneous properties of self social status and dynamic status in the real directed signed social networks. Our present work provides some interesting tools and perspective to understand the signs' configuration in signed social networks, especially in the online affiliation networks.

    The diagnosis of cervical dystonia (CD) is clinical. We describe a physical examination observation that has been noted in CD patients. There is a tendency for their shirt collars to be shifted to one side. We validated this apparently consistent finding by having blinded evaluators rating the symmetry of the shirt collars in CD and non-cervical dystonia control subjects. A high correlation was found between the physical finding which we call "shirt collar sign" and the diagnosis. "Shirt collar sign" may be a helpful sign in diagnosing CD.

    Martin, M; Jones, G V

    1998-03-01

    Memory for frequently encountered road signs was investigated. In Experiment 1, the average level of recall of road sign features was found to be only 47%. In Experiment 2, more left-handed than right-handed people recalled that a walking figure faces right on one sign, whereas more right-handed than left-handed people recalled that a digging figure faces left on another sign. Performance thus reflected not a difference in level of mnemonic ability between left-handed and right-handed groups but instead the compatibility between group and task. In Experiment 3, participants were asked to draw any figure walking and any figure digging, with a pattern of results similar to that of Experiment 2. It is suggested that handedness effects in recall are mediated by motor imagery.

  17. The Babinski sign and the pyramidal syndrome.

    Science.gov (United States)

    Van Gijn, J

    1978-10-01

    The presence or absence of a Babinski sign can be puzzling, but in the light of existing pathological studies it is more fruitful to consider which pyramidal tract fibres release it than whether they release it. This was investigated clinically, by looking for correlations with other reflex changes and with motor deficits in the leg. A survey of 50 patients with a unilateral Babinski sign and six patients who lacked it in spite of other pyramidal tract signs was supplemented with follow-up of the patients who had acute lesions. Appearance of the Bibinski sign proved to depend on the interaction of two factors: (1) activity (not necessarily hyperactivity) in the segmental pathways of the flexion synergy; (2) a motor deficit of the foot, in some cases consisting only in an impairment of rapid foot movements, and probably representing a disturbance of direct pyramidal tract projections to distal motoneurones.

  18. Holographic strange metals, entanglement and fermion signs

    CERN Document Server

    Kaplis, N; Zaanen, J

    2016-01-01

    The fermion sign problem is often viewed as a sheer inconvenience that plagues numerical studies of strongly interacting electron systems. Only recently, it has been suggested that fermion signs are fundamental for the universal behavior of critical metallic systems and crucially enhance their degree of quantum entanglement. In this work we explore potential connections between emergent scale invariance of fermion sign structures and scaling properties of bipartite entanglement entropies. Our analysis is based on a wavefunction ansatz that incorporates collective, long-range backflow correlations into fermionic Slater determinants. Such wavefunctions mimic the collapse of a Fermi liquid at a quantum critical point. Their nodal surfaces -- a representation of the fermion sign structure in many-particle configurations space -- show fractal behavior up to a length scale $\\xi$ that diverges at a critical backflow strength. We show that the Hausdorff dimension of the fractal nodal surface depends on $\\xi$, the num...

    2009-10-01

    Working memory (WM) for sign language has an architecture similar to that for speech-based languages at both functional and neural levels. However, there are some processing differences between language modalities that are not yet fully explained, although a number of hypotheses have been mooted. This article reviews some of the literature on differences in sensory, perceptual and cognitive processing systems induced by auditory deprivation and sign language use and discusses how these differences may contribute to differences in WM architecture for signed and speech-based languages. In conclusion, it is suggested that left-hemisphere reorganization of the motion-processing system as a result of native sign-language use may interfere with the development of the order processing system in WM.

Evidence is presented to show that the line is a radiological shadow cast by the lateral edge of a severely deformed femoral head rather than a condensation of the spongiosa within the neck. An explanation is offered to explain the common association of the presence of this radiological sign with premature epiphysial fusion.

  5. On the temporal dynamics of sign production: An ERP study in Catalan Sign Language (LSC).

    Science.gov (United States)

    Baus, Cristina; Costa, Albert

    2015-06-03

    This study investigates the temporal dynamics of sign production and how particular aspects of the signed modality influence the early stages of lexical access. To that end, we explored the electrophysiological correlates associated to sign frequency and iconicity in a picture signing task in a group of bimodal bilinguals. Moreover, a subset of the same participants was tested in the same task but naming the pictures instead. Our results revealed that both frequency and iconicity influenced lexical access in sign production. At the ERP level, iconicity effects originated very early in the course of signing (while absent in the spoken modality), suggesting a stronger activation of the semantic properties for iconic signs. Moreover, frequency effects were modulated by iconicity, suggesting that lexical access in signed language is determined by the iconic properties of the signs. These results support the idea that lexical access is sensitive to the same phenomena in word and sign production, but its time-course is modulated by particular aspects of the modality in which a lexical item will be finally articulated.

    2017-02-01

    Most studies of disease spreading consider the underlying social network as obtained without the contagion, though epidemic influences people's willingness to contact others: A "friendly" contact may be turned to "unfriendly" to avoid infection. We study the susceptible-infected disease-spreading model on signed networks, in which each edge is associated with a positive or negative sign representing the friendly or unfriendly relation between its end nodes. In a signed network, according to Heider's theory, edge signs evolve such that finally a state of structural balance is achieved, corresponding to no frustration in physics terms. However, the danger of infection affects the evolution of its edge signs. To describe the coupled problem of the sign evolution and disease spreading, we generalize the notion of structural balance by taking into account the state of the nodes. We introduce an energy function and carry out Monte Carlo simulations on complete networks to test the energy landscape, where we find local minima corresponding to the so-called jammed states. We study the effect of the ratio of initial friendly to unfriendly connections on the propagation of disease. The steady state can be balanced or a jammed state such that a coexistence occurs between susceptible and infected nodes in the system.

  8. [C-sign and talocalcaneal coalition].

    Science.gov (United States)

    Tomčovčík, L

    2011-01-01

    Talocalcaneal coalition is an abnormal bridge between talus and calcaneus, causing pain and restriction of subtalar movement; its incidence is less than 1 %. The signs and symptoms usually become manifest in the second decade of life with ossification of the lesion. They involve flat foot, peroneal muscle spasm, tarsal tunnel syndrome, or valgus tilt of the heel. The sings need not be noticeable and may appear only as tiredness and vague pain in the hind foot after exercise or an easily twisted ankle. The authors describe the case of talocalcaneal coalition in a 20-year-old man, incidentally diagnosed at ankle fracture. The presence of C-sign led to CT examination and the exact diagnosis. Radiological demonstration of this abnormality may be difficult because plain X-ray images in both projections may show normal findings. Literature data report, in addition to C-sign, further secondary signs of talocalcaneal coalition present on lateral radiographs of the ankle joint. Although these signs do not directly point to talocalcaneal coalition, they reveal abnormal anatomy or movement of the joint and may initiate more thorough examination by CT or MRI and the establishment of an exact diagnosis. Therefore, to know the secondary signs and pay attention to them is very useful.

  9. Gesture, sign and language: The coming of age of sign language and gesture studies.

    Science.gov (United States)

    Goldin-Meadow, Susan; Brentari, Diane

    2015-10-05

    How does sign language compare to gesture, on the one hand, and to spoken language on the other? At one time, sign was viewed as nothing more than a system of pictorial gestures with no linguistic structure. More recently, researchers have argued that sign is no different from spoken language with all of the same linguistic structures. The pendulum is currently swinging back toward the view that sign is gestural, or at least has gestural components. The goal of this review is to elucidate the relationships among sign language, gesture, and spoken language. We do so by taking a close look not only at how sign has been studied over the last 50 years, but also at how the spontaneous gestures that accompany speech have been studied. We come to the conclusion that signers gesture just as speakers do. Both produce imagistic gestures along with more categorical signs or words. Because, at the moment, it is difficult to tell where sign stops and where gesture begins, we suggest that sign should not be compared to speech alone, but should be compared to speech-plus-gesture. Although it might be easier (and, in some cases, preferable) to blur the distinction between sign and gesture, we argue that making a distinction between sign (or speech) and gesture is essential to predict certain types of learning, and allows us to understand the conditions under which gesture takes on properties of sign, and speech takes on properties of gesture. We end by calling for new technology that may help us better calibrate the borders between sign and gesture.

    Dendritic cell-specific ICAM-3-grabbing non-integrin (DC-SIGN/CD209) and liver/lymph node-specific ICAM-grabbing non-integrin (L-SIGN/CD299) which are homologues of DC-SIGN are important members in C-type lectin receptors family as key molecules to recognize and eliminate pathogens in the innate immune system. DC-SIGN and L-SIGN have become hot topics in recent studies which both served as cell adhesion and phagocytic pathogen recognition receptors in mammals. However, there have been almost no studies of DC-SIGN and L-SIGN structure and characters in fish, only DC-SIGN in the zebrafish had been studied. In our study, we identified and characterized the full-length miiuy croaker (Miichthys miiuy) DC-SIGN (mmDC-SIGN) and L-SIGN (mmL-SIGN) genes. The sequence analysis results showed that mmDC-SIGN and mmL-SIGN have the same domains with other vertebrates except primates, and share some conserved motifs in CRD among all the vertebrates which play a crucial role in interacting with Ca(2+) and for recognizing mannose-containing motifs. Gene synteny of DC-SIGN and L-SIGN were analyzed for the first time and gene synteny of L-SIGN was conserved among the five fishes. Interestingly, one gene next to L-SIGN from gene synteny had high similarity with L-SIGN gene that was described as L-SIGN-like in fish species. While only one L-SIGN gene existed in other vertebrates, two L-SIGN in fish may be in consequence of the fish-specific genome duplication to adapt the specific environment. The evolutionary analysis showed that the ancestral lineages of L-SIGN gene in fishes experienced purifying selection and the current lineages of L-SIGN gene in fishes underwent positive selection, indicating that the ancestral lineages and current lineages of L-SIGN gene in fishes underwent different evolutionary patterns. Both mmDC-SIGN and mmL-SIGN were expressed in all tested tissues and ubiquitously up-regulated in infected liver, spleen and kidney at different sampling time points

    Signed languages continue to be a key element of deaf education programs that incorporate a bilingual approach to teaching and learning. In order to monitor the success of bilingual deaf education programs, and in particular to monitor the progress of children acquiring signed language, it is essential to develop an assessment tool of signed language skills. Although researchers have developed some checklists and experimental tests related to American Sign Language (ASL) assessment, at this time a standardized measure of ASL does not exist. There have been tests developed in other signed languages, for example, British Sign Language, that can serve as models in this area. The purpose of this study was to adapt the Assessing British Sign Language Development: Receptive Skills Test for use in ASL in order to begin the process of developing a standardized measure of ASL skills. The results suggest that collaboration between researchers in different signed languages can provide a valuable contribution toward filling the gap in the area of signed language assessment.

  15. On the System of Place Name Signs in Estonian Sign Language

    Directory of Open Access Journals (Sweden)

    Liina Paales

    2010-12-01

    Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

  20. Sign ambiguity in the K Sigma channel

    Anisovich, A V; Nikonov, V A; Sarantsev, A V; Thoma, U

    2013-01-01

    Ambiguities of the signs of $N\\to \\Sigma K$ coupling constants are studied in a multichannel partial wave analysis of a large body of pion and photo-induced reactions. It is shown that the signs are not free from some ambiguities, and further experimental data are needed. Data on the reactions $\\pi^+p\\to \\Sigma^+K^+$ and $\\gamma p\\to K^+\\Sigma^0$ define rather well the isospin 3/2 contributions to these channels. However the lack of information on polarization observables for the reactions $\\pi^-p\\to \\Sigma^0K^0$, $\\pi^-p\\to \\Sigma^-K^+$ and $\\gamma p\\to K^0\\Sigma^+$ does not allow us to fix uniquely the signs of $N\\to \\Sigma K$ coupling constants. As a consequence, also the contributions of nucleon resonances to these channels remain uncertain.

    Although the "face of the giant panda" sign on magnetic resonance imaging (MRI) is traditionally considered to be characteristic of Wilson disease, it has also been reported in other metabolic disorders. This study describes the characteristic "giant panda" sign on MRI in a child with Leigh disease. The diagnosis was based on the history of neurological regression; examination findings of oculomotor abnormalities, hypotonia, and dystonia; raised serum lactate levels; and characteristic brain stem and basal ganglia signal changes on MRI. The midbrain and pontine tegmental signal changes were consistent with the "face of the giant panda and her cub" sign. In addition to Wilson disease, metabolic disorders such as Leigh disease should also be considered in the differential diagnosis of this rare imaging finding.

  2. Sign Stability via Root Locus Analysis

    CERN Document Server

    Gibson, Travis E

    2015-01-01

    With the rise of network science old topics in ecology and economics are resurfacing. One such topic is structural stability (often referred to as qualitative stability or sign stability). A system is deemed structurally stable if the system remains stable for all possible parameter variations so long as the parameters do not change sign. This type of stability analysis is appealing when studying real systems as the underlying stability result only requires the scientist or engineer to know the sign of the parameters in the model and not the specific values. The necessary and sufficient conditions for qualitative stability however are opaque. In order to shed light on those conditions root locus analysis is employed. This technique allows us to illustrate the necessary conditions for qualitative stability.

  3. A Sign Language Screen Reader for Deaf

    El Ghoul, Oussama; Jemni, Mohamed

    Screen reader technology has appeared first to allow blind and people with reading difficulties to use computer and to access to the digital information. Until now, this technology is exploited mainly to help blind community. During our work with deaf people, we noticed that a screen reader can facilitate the manipulation of computers and the reading of textual information. In this paper, we propose a novel screen reader dedicated to deaf. The output of the reader is a visual translation of the text to sign language. The screen reader is composed by two essential modules: the first one is designed to capture the activities of users (mouse and keyboard events). For this purpose, we adopted Microsoft MSAA application programming interfaces. The second module, which is in classical screen readers a text to speech engine (TTS), is replaced by a novel text to sign (TTSign) engine. This module converts text into sign language animation based on avatar technology.

    The present study tries to investigate the people’s attitude to the use of English words in TV commercials, brand-naming and shop signs in Iran and specifically in Tehran where due to the fact that it is the capital, more English might be used for the sake of foreigners. The widespread use of English shop signs and English brand names for recently produced goodsdrove the researchers to investigate peoples’ attitude as consumers from two aspects of age and education. To reach the research goal, a questionnaire was devised and distributed to 100 people at random selection probing their attitudes while considering two factors of age and education. The result of the research will mostly benefit sociolinguists and business marketers.

Our first contribution is an extension of $c_\\Gamma(k,l)$ to signed graphs, for which we obtain an inclusion--exclusion formula and several special evaluations giving rise, e.g., to polynomials that encode balanced subgraphs. Our second goal is to derive combinatorial reciprocity theorems for $c_\\Gamma(k,l)$ and its signed-graph analogues, reminiscent of Stanley's reciprocity theorem linking chromatic polynomials to acyclic orientations.

    Safety belts are the most important safety system in motor vehicles and when worn intend to prevent serious injuries. However, in unusual circumstances (high velocity motor vehicle collisions) these safety measures (seat belts) can be the source and cause of serious injuries. The seat belt syndrome was first described as early by Garrett and Braunste in but the term "seat belt sign" was discussed by Doersch and Dozier. Medical personnel's involved in emergency care of trauma patients should be aware of seat belt sign and there should a higher index of suspicion to rule out underlying organ injuries.

  13. Cycles and Dynamics on Evolving Signed Digraphs

    CERN Document Server

    MacArthur, Ben D; Ma'ayan, Avi

    2009-01-01

    We consider a simple model which couples structural evolution of signed directed graphs to dynamic stability. The resulting systems self-organize to a complex dynamical state characterized by periods of stability punctuated by intermittent bursts of instability. By deriving analytical relationships between cyclic structure, cycle balance, and global stability in signed digraphs we show that the observed bursting dynamics result from the continual formation and breaking of transient directed cycles during the evolutionary process. At equilibrium bursts of instability develop heavy-tailed statistics suggesting a possible self-organized critical state.

    Due to the presence of light pions in the theory, lattice QCD at finite densities suffers from issues with noise in both grand canonical and canonical formulations. We study two different formulations of the Nambu-Jona-Lasinio model reduced to 2+1 dimensions at large N, where N is the number of flavors. At finite chemical potential one formulation has a severe sign problem and a fermion correlator which displays a broad probability distribution with small mean. In the other we find no sign problem and a distribution amenable to the cumulant expansion techniques developed in earlier work.

    Lexical comprehension and production is directly evaluated for the first time in deaf signing children below the age of 3 years. A Picture Naming Task was administered to 8 deaf signing toddlers (aged 2-3 years) who were exposed to Sign Language since birth. Results were compared with data of hearing speaking controls. In both deaf and hearing children, comprehension was significantly higher than production. The deaf group provided a significantly lower number of correct responses in production than did the hearing controls, whereas in comprehension, the 2 groups did not differ. Difficulty and ease of items in comprehension and production was similar for signing deaf children and hearing speaking children, showing that, despite size differences, semantic development followed similar paths. For signing children, predicates production appears easier than nominals production compared with hearing children acquiring spoken language. Findings take into account differences in input modalities and language structures.

    DC-SIGN, a dendritic Cell-specific adhesion receptor and a type Ⅱ transmembrane mannose-binding C-type lectin, is very important in the function of DC, both in mediating naive T cell interactions through ICAM-3 and as a rolling receptor that mediates the DC-specific ICAM-2-dependent migration processes. It can be used by viral and bacterial pathogens including Human Immunodeficiency Virus (HIV), HCV, Ebola Virus, CMV and Mycobacterium tuberculosis to facilitate infection. Both DC-SIGN and DC-SIGNR can act either in cis,by concentrating virus on target cells, or in trans, by transmission of bound virus to a target cell expressing appropropriate entry receptors. Recent work showed that DC-SIGN are highaffinity binding receptors for HCV. Besides playing a role in entry into DC, HCV E2 interaction with DC-SIGN might also be detrimental for the interaction of DC with T cells during antigen presentation. The clinical strategies that target DCSIGN may be successful in restricting HCV dissemination and pathogenesis as well as directing the migration of DCs to manipulate appropriate immune responses in autoimmunity and tumorigenic situations.

    2015-01-01

    Psycholinguistic studies of sign language processing provide valuable opportunities to assess whether language phenomena, which are primarily studied in spoken language, are fundamentally shaped by peripheral biology. For example, we know that when given a choice between two syntactically permissible ways to express the same proposition, speakers tend to choose structures that were recently used, a phenomenon known as syntactic priming. Here, we report two experiments testing syntactic priming of a noun phrase construction in American Sign Language (ASL). Experiment 1 shows that second language (L2) signers with normal hearing exhibit syntactic priming in ASL and that priming is stronger when the head noun is repeated between prime and target (the lexical boost effect). Experiment 2 shows that syntactic priming is equally strong among deaf native L1 signers, deaf late L1 learners, and hearing L2 signers. Experiment 2 also tested for, but did not find evidence of, phonological or semantic boosts to syntactic priming in ASL. These results show that despite the profound differences between spoken and signed languages in terms of how they are produced and perceived, the psychological representation of sentence structure (as assessed by syntactic priming) operates similarly in sign and speech.

    Getting to wounded soldiers on the battlefield is a precarious task, and medics have a very high casualty rate. It is therefore a vital importance to prioritize which soldiers to attend to first. The first step is to detect life signs - if a soldier is dead or alive, and prioritize recovery of live soldiers. The second step is to obtain vital signs from live soldiers, and use this to prioritize which are in most urgent need of attention. Our team at Kai Sensors, University of Hawaii and University of Florida is developing Doppler radar heart sensing technology that provides the means to detect life signs, respiration and/or heart beat, at a distance, even for subjects lying motionless, e.g., unconscious subjects, wearing body armor, and hidden from direct view. Since this technology can deliver heart rate information with high accuracy, it may also enable the assessment of a subject's physiological and psychological state based on heart rate variability (HRV) analysis. Thus, the degree of a subject's injury may also be determined. The software and hardware developments and challenges for life signs detection and monitoring for battlefield triage will be discussed, including heart signal detection from all four sides of the human body, detection in the presence of body armor, and the feasibility of HRV parameter extraction.

    Teaching science to school children with hearing deficiency and impairment can be a rewarding and valuable experience for both teacher and student, and necessary to society as a whole in order to reduce the discriminative policies in the formal educational system. The one most important obstacle to the teaching of science to students with hearing deficiency and impairments is the lack of vocabulary in sign language to express the precise concepts encountered in scientific endeavor. In a collaborative project between Centro de Investigaciones de Astronomía ``Francisco J. Duarte'' (CIDA), Universidad Pedagógica Experimental Libertador-Instituto Pedagógico de Maturín (UPEL-IPM) and Unidad Educativa Especial Bolivariana de Maturín (UEEBM) initiated in 2006, we have attempted to fill this gap by developing signs for astronomy and space sciences terminology. During two three-day workshops carried out at CIDA in Mérida in July 2006 and UPEL-IPM in Maturín in March 2007 a total of 112 concepts of astronomy and space sciences were coined in sign language using an interactive method which we describe in the text. The immediate goal of the project is to incorporate these terms into Venezuelan Sign Language (LSV).

    1995-04-01

    One of the natural methods of tactual communication in common use among individuals who are both deaf and blind is the tactual reception of sign language. In this method, the receiver (who is deaf-blind) places a hand (or hands) on the dominant (or both) hand(s) of the signer in order to receive, through the tactual sense, the various formational properties associated with signs. In the study reported here, 10 experienced deaf-blind users of either American Sign Language (ASL) or Pidgin Sign English (PSE) participated in experiments to determine their ability to receive signed materials including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87% correct. The most frequent type of error made in identifying isolated signs was related to misperception of individual phonological components of signs. For presentation of signed sentences (translations of the English CID sentences into ASL or PSE), the performance of individual subjects ranged from 60-85% correct reception of key signs. Performance on sentences was relatively independent of rate of presentation in signs/sec, which covered a range of roughly 1 to 3 signs/sec. Sentence errors were accounted for primarily by deletions and phonological and semantic/syntactic substitutions. Experimental results are discussed in terms of differences in performance for isolated signs and sentences, differences in error patterns for the ASL and PSE groups, and communication rates relative to visual reception of sign language and other natural methods of tactual communication.

We find that, while subnetworks in which links have a positive connotation, such as endorsement and trust, are characterized by assortative mixing by degree, networks in which links have a negative connotation, such as disapproval and distrust, are characterized by disassortative patterns. We introduce a class of simple theoretical models to analyze the interplay between network topology and the superimposed structure based on the sign of links. Results uncover the conditions that underpin the emergence of the patterns observed in the data, namely the assortativity of positive subnetworks and the disassortativity of negative ones. We discuss the implications of our study for the analysis of signed complex networks.

    The canonical approach, which was developed for solving the sign problem, may suffer from a new type of sign problem. In the canonical approach, the grand partition function is written as a fugacity expansion: $Z_G(\\mu,T) = \\sum_n Z_C(n,T) \\xi^n$, where $\\xi=\\exp(\\mu/T)$ is the fugacity, and $Z_C(n,T)$ are given as averages over a Monte Carlo update, $\\langle z_n\\rangle$. We show that the complex phase of $z_n$ is proportional to $n$ at each Monte Carlo step. Although $\\langle z_n\\rangle$ take real positive values, the values of $z_n$ fluctuate rapidly when $n$ is large, especially in the confinement phase, which gives a limit on $n$. We discuss possible remedies for this problem.

The theory offers a tool for robust parsing of lexical transfer errors and diagnosis of such errors.

    Estañol Vidal, B; Huerta Díaz, E; García Ramos, G

    1997-01-01

    In 1896 Joseph Francois Felix Babinski described for the first time the phenomenon of the toes. In his first paper he simply described extension of all toes with noxious stimulation of the sole of the foot. It was not until 1898 that he specifically described the extension of the hallux with stimulation of the lateral border of the sole. Babinski was probably not aware at the time that E. Remak, a German physician, had previously described the sign. In his third paper of 1903 Babinski concludes that if other authors had described the abnormal reflex before him, they found it fortuitously and did not realize its semiologic value. Babinski probably discovered it by a combination of chance, careful observation and intuition. He also had in mind practical applications of the sign particularly in the differential diagnosis with hysteria and in medico-legal areas. Several of his observations and the physiopathological mechanism proposed by him are still valid today. He realized since 1896 that the Babinski reflex was part of the flexor reflex synergy. He observed that several patients during the first hours of an acute cerebral or spinal insult had absent extensor reflexes. He realized that most patients with the abnormal reflex had weakness of the toes and ankles. He found a lack of correlation between hyperactive myotatic reflexes and the presence of an upgoing hallux. He discovered that not all patients with hemiplegia or paraplegia had the sign. He thought erroneously that some normal subjects could have an upgoing toe. His dream of a practical application of the sign has been fully achieved. The motto of Babinski was Observatio summa lex. Perhaps there is no better dictum in clinical neurology.

To address this question, here we gauge the generalization afforded by American Sign Language (ASL. As a case study, we examine reduplication (X→XX—a rule that, inter alia, generates ASL nouns from verbs. If signers encode this rule, then they should freely extend it to novel syllables, including ones with features that are unattested in ASL. And since reduplicated disyllables are preferred in ASL, such rule should favor novel reduplicated signs. Novel reduplicated signs should thus be preferred to nonreduplicative controls (in rating, and consequently, such stimuli should also be harder to classify as nonsigns (in the lexical decision task. The results of four experiments support this prediction. These findings suggest that the phonological knowledge of signers includes powerful algebraic rules. The convergence between these conclusions and previous evidence for phonological rules in spoken language suggests that the architecture of the phonological mind is partly amodal.

    While Alois Alzheimer recognized the effects of the disease he described on speech and language in his original description of the disease in 1907, the effects of Alzheimer's disease (AD) on language in deaf signers has not previously been reported. We evaluated a 55-year-old right-handed congenitally deaf woman with a 2-year history of progressive memory loss and a deterioration of her ability to communicate in American Sign Language, which she learned at the age of eight. Examination revealed that she had impaired episodic memory as well as marked impairments in the production and comprehension of fingerspelling and grammatically complex sentences. She also had signs of anomia as well as an ideomotor apraxia and visual-spatial dysfunction. This report illustrates the challenges in evaluation of a patient for the presence of degenerative dementia when the person is deaf from birth, uses sign language, and has a late age of primary language acquisition. Although our patient could neither speak nor hear, in many respects her cognitive disorders mirror those of patients with AD who had normally learned to speak.

  1. The halo sign and peripancreatic fluid: useful CT signs of hypovolaemic shock complex in adults

    2005-05-01

    AIM: To report two new, useful computed tomography (CT) signs of the hypovolaemic shock complex (HSC) in adults admitted after blunt abdominal trauma: the halo sign (ring of fluid around a collapsed intra-hepatic inferior vena cava (IVC)), and peripancreatic retroperitoneal fluid. MATERIALS AND METHODS: CT images of 498 consecutive patients admitted after blunt abdominal trauma were reviewed, of which 27 had CT signs of the HSC. The CT images of these 27 patients were analysed. A control group of 101 patients examined using CT for suspected blunt abdominal trauma who did not have the HSC were chosen for comparison. RESULTS: The most common features involved the vascular compartment: diminished IVC diameter (n=27), a positive halo sign (n=21); diminished anteroposterior diameter of the aorta (n=13); and abnormal vascular enhancement (n=10). Peripancreatic retroperitoneal fluid in the absence of pancreatic injury, pancreatitis or pancreatic disease was observed in eight patients. Hollow visceral abnormalities included: diffuse increased mucosal enhancement of both the small and large bowel (n=19); diffuse thickening of the small bowel wall (n=11); and small bowel dilatation (n=7). Solid visceral abnormalities included both decreased and or increased enhancement. Several concomitant intra- and extra-abdominal injuries were also identified. CONCLUSION: In the setting of blunt abdominal trauma, early abdominal CT can show diffuse abnormalities due to the HSC, which occasionally may alert clinicians of unsuspected shock. Recognition of these signs as distinguished from injured viscera is important in order to avoid unnecessary laparotomy. Two new signs are described: the halo sign and peripancreatic retroperitoneal fluid.

    Full Text Available In the communication of deaf people between them­selves and hearing people there are three ba­sic as­pects of interaction: gesture, finger signs and writing. The gesture is a conditionally agreed manner of communication with the help of the hands followed by face and body mimic. The ges­ture and the move­ments pre-exist the speech and they had the purpose to mark something, and later to emphasize the speech expression.Stokoe was the first linguist that realised that the signs are not a whole that can not be analysed. He analysed signs in insignificant parts that he called “chemeres”, and many linguists today call them pho­nemes. He created three main phoneme catego­ries: hand position, location and movement.Sign languages as spoken languages have back­ground from the distant past. They developed par­allel with the development of spoken language and undertook many historical changes. Therefore, to­day they do not represent a replacement of the spoken language, but are languages themselves in the real sense of the word.Although the structures of the English language used in USA and in Great Britain is the same, still their sign languages-ASL and BSL are different.

    2013-06-01

    Hepatic encephalopathy (HE) is a manifestation of clinical signs that may result from a variety of liver diseases. In small animals, HE is most commonly a result of portosystemic shunting. The pathogenesis is not completely understood, although it is likely multifactorial. Theories of pathogenesis include altered ammonia metabolism and glutamine and glutamate transmission, an increase in gamma-aminobutyric acid agonists and benzodiazepine-like substances, alterations of the serotonergic system and amino acid metabolism, elevated taurine levels, contributions from inflammatory mediators, and toxic effects of manganese. An understanding of the underlying mechanisms that result in HE may lead to new treatments in the future.

    Signed 3D distance fields are used a in a variety of domains. From shape modelling to surface registration. They are typically computed based on sampled point sets. If the input point set contains holes, the behaviour of the zero-level surface of the distance field is not well defined...... Cholesky factorisation. It is demonstrated that the zero-level surface will act as a membrane after the proposed regularisation. This effectively closes holes in a predictable way. Finally, the performance of the method is tested with a set of synthetic point clouds of increasing complexity....

    Referring to examples from the poetry of Fernando Pessoa and Mário de Sá Carneiro, we draw attention to the narcissistic relationship between mother and baby, to the role of the mirror-image of the mother's face, and to the organization of a false self caused by a deficiency both of that function, and of the narcissistic investment of the child. The false self is a defence mechanism which protects the true self. This may appear as a depressive state with a feeling of loss and emptiness. The depression is, in such cases, a sign and a clue which may lead to the revelation of the true self.

    Every year, 10,000 infants are born in the United States with sensorineural deafness. Deaf children of hearing (and nonsigning) parents are unique among all children in the world in that they cannot easily or naturally learn the language that their parents speak. These parents face tough choices. Should they seek a cochlear implant for their child? If so, should they also learn to sign? As pediatricians, we need to help parents understand the risks and benefits of different approaches to parent-child communication when the child is deaf [corrected].

    Singnurkar, Amit; Rush, Chris

    2006-11-01

    Fibrous dysplasia commonly involves the skull in both its monostotic and polyostotic variants. We present two cases of fibrous dysplasia involving the sphenoid wing, which were strikingly similar in their bone scan appearance. Both patients demonstrated intense increased uptake of Tc-99m MDP in a pattern reminding us of a "pirate wearing an eyepatch." We propose that this characteristic appearance of fibrous dysplasia of the sphenoid wing be called the "pirate sign." A review of the literature revealed several other pathologic conditions that have been reported to involve the sphenoid bone and should be considered in the differential diagnosis of abnormal bone tracer uptake in this region.

    2011-12-15

    We present a fair and optimistic quantum-contract-signing protocol between two clients that requires no communication with the third trusted party during the exchange phase. We discuss its fairness and show that it is possible to design such a protocol for which the probability of a dishonest client to cheat becomes negligible and scales as N{sup -1/2}, where N is the number of messages exchanged between the clients. Our protocol is not based on the exchange of signed messages: Its fairness is based on the laws of quantum mechanics. Thus, it is abuse free, and the clients do not have to generate new keys for each message during the exchange phase. We discuss a real-life scenario when measurement errors and qubit-state corruption due to noisy channels and imperfect quantum memories occur and argue that for a real, good-enough measurement apparatus, transmission channels, and quantum memories, our protocol would still be fair. Apart from stable quantum memories, the other segments of our protocol could be implemented by today's technology, as they require in essence the same type of apparatus as the one needed for the Bennett-Brassard 1984 (BB84) cryptographic protocol. Finally, we briefly discuss two alternative versions of the protocol, one that uses only two states [based on the Bennett 1992 (B92) protocol] and the other that uses entangled pairs, and show that it is possible to generalize our protocol to an arbitrary number of clients.

    Full Text Available Abstract Objective Determination of the prevalence of tobacco use and impact of tobacco prevention/treatment efforts in an electronic medical record enabled practice utilizing a defined tobacco vital sign variable. Design and Measurements Retrospective cohort study utilizing patient data recorded in an electronic medical record database between July 15, 2001, and May 31, 2003. Patient-reported tobacco use status was obtained for each of 6,771 patients during the pre-provider period of their 24,824 visits during the study period with the recorder blinded to past tobacco use status entries. Results An overall current tobacco use prevalence of 27.1% was found during the study period. Tobacco use status was recorded in 96% of visits. Comparison of initial to final visit tobacco use status demonstrates a consistency rate of 75.0% declaring no change in tobacco status in the 4,522 patients with two or more visits. An 8.6% net tobacco use decline was seen for the practice (p value Conclusion Self reported tobacco use status as a vital sign embedded within the workflow of an electronic medical record enabled practice was a quantitative tool for determination of tobacco use prevalence and a measuring stick of risk prevention/intervention impact.

    Full Text Available Among the medieval, mostly anonymous, works, the runic inscriptions from the Swedish province Uppland are surprisingly frequently signed with the author’s name. The runic masters (Swedish runristare, the first Scandinavian authors known by name, have been the focus of academic interest since Otto von Friesen’s (1913, 1933 and Erik Brate’s (1925 publications, with new findings published more recently (Thompson 1975, Philippa 1977, Quak 1978, Crocker 1982, Åhlén 1997, Källström 1999 i 2007. The present article is a short presentation of the signature types used by the runic masters from Uppland in the 11th and 12th century and of the most important members of the possible runic guild of that time. A typology of signatures concerning the type of work done on the inscriptions is given (different activities conducted by different people suggest that the preparation of an inscription was a collective rather than individual work. At the same, the comparison between the older and the more recent signed inscriptions suggests that the runic alphabet has evolved from a magical to a common tool. Also, three most eminent runic masters, Ulf of Borresta, Öpir and Åsmund Kåresson, and their inscriptions are presented in the text.

  17. Wearable system for vital signs monitoring.

    Science.gov (United States)

    Paradiso, Rita; Loriga, Gianni; Taccini, Nicola

    2004-01-01

    A new concept in healthcare, aimed at providing continuous remote monitoring of user's vital signs, is emerging. An innovative system named WEALTHY is presented, where conducting and piezoresistive materials in the form of fiber and yarn are integrated and used as sensor and electrode elements. The simultaneous recording of vital signs allows parameter extrapolation and inter-signal elaboration that contribute to producing alert messages and synoptic patient tables. Cardiac patients in the rehabilitation phase can be continuously monitored during selected time intervals, such as during physical activity or occurrence of symptoms, to discover potential threats and generate appropriate alerts to the patient and/or to an emergency center. The core of the system sensing is a textile interface, in which the sensing components are elements of the fabric: the sensorized garment is comfortable like a common article of clothing and is made with knitting machines; furthermore, the position of the electrodes and sensors is fixed and the elasticity of the fabric allows a good fitting to the body. The system is provided with a portable electronic unit, where signals are acquired, elaborated and transmitted. A monitoring system allows extrapolation of a new physiological index and data flow coordination as well as alarm management and database creation.

  18. "Ostrich sign" indicates bilateral vertebral artery dissection.

    Science.gov (United States)

    Rose, David Z; Husain, M Rizwan

    2012-11-01

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

  19. Synesthesia for manual alphabet letters and numeral signs in second-language users of signed languages.

    Many synesthetes experience colors when viewing letters or digits. We document, for the first time, an analogous phenomenon among users of signed languages who showed color synesthesia for fingerspelled letters and signed numerals. Four synesthetes experienced colors when they viewed manual letters and numerals (in two cases, colors were subjectively projected on to the hands). There was a correspondence between the colors experienced for written graphemes and their manual counterparts, suggesting that the development of these two types of synesthesia is interdependent despite the fact that these systems are superficially distinct and rely on different perceptual recognition mechanisms in the brain.

  20. Study on road sign recognition in LabVIEW

    Panoiu, M.; Rat, C. L.; Panoiu, C.

    2016-02-01

    Road and traffic sign identification is a field of study that can be used to aid the development of in-car advisory systems. It uses computer vision and artificial intelligence to extract the road signs from outdoor images acquired by a camera in uncontrolled lighting conditions where they may be occluded by other objects, or may suffer from problems such as color fading, disorientation, variations in shape and size, etc. An automatic means of identifying traffic signs, in these conditions, can make a significant contribution to develop an Intelligent Transport Systems (ITS) that continuously monitors the driver, the vehicle, and the road. Road and traffic signs are characterized by a number of features which make them recognizable from the environment. Road signs are located in standard positions and have standard shapes, standard colors, and known pictograms. These characteristics make them suitable for image identification. Traffic sign identification covers two problems: traffic sign detection and traffic sign recognition. Traffic sign detection is meant for the accurate localization of traffic signs in the image space, while traffic sign recognition handles the labeling of such detections into specific traffic sign types or subcategories [1].

  20. Link Label Prediction in Signed Citation Network

    KAUST Repository

    Akujuobi, Uchenna

    2016-04-12

    Link label prediction is the problem of predicting the missing labels or signs of all the unlabeled edges in a network. For signed networks, these labels can either be positive or negative. In recent years, different algorithms have been proposed such as using regression, trust propagation and matrix factorization. These approaches have tried to solve the problem of link label prediction by using ideas from social theories, where most of them predict a single missing label given that labels of other edges are known. However, in most real-world social graphs, the number of labeled edges is usually less than that of unlabeled edges. Therefore, predicting a single edge label at a time would require multiple runs and is more computationally demanding. In this thesis, we look at link label prediction problem on a signed citation network with missing edge labels. Our citation network consists of papers from three major machine learning and data mining conferences together with their references, and edges showing the relationship between them. An edge in our network is labeled either positive (dataset relevant) if the reference is based on the dataset used in the paper or negative otherwise. We present three approaches to predict the missing labels. The first approach converts the label prediction problem into a standard classification problem. We then, generate a set of features for each edge and then adopt Support Vector Machines in solving the classification problem. For the second approach, we formalize the graph such that the edges are represented as nodes with links showing similarities between them. We then adopt a label propagation method to propagate the labels on known nodes to those with unknown labels. In the third approach, we adopt a PageRank approach where we rank the nodes according to the number of incoming positive and negative edges, after which we set a threshold. Based on the ranks, we can infer an edge would be positive if it goes a node above the

    2009-04-01

    Do all components of a sign contribute equally to its recognition? In the present study, misperceptions in the sign-spotting task (based on the word-spotting task; Cutler & Norris, 1988) were analyzed to address this question. Three groups of deaf signers of British Sign Language (BSL) with different ages of acquisition (AoA) saw BSL signs combined with nonsense signs, along with combinations of two nonsense signs. They were asked to spot real signs and report what they had spotted. We will present an analysis of false alarms to the nonsense-sign combinations-that is, misperceptions of nonsense signs as real signs (cf. van Ooijen, 1996). Participants modified the movement and handshape parameters more than the location parameter. Within this pattern, however, there were differences as a function of AoA. These results show that the theoretical distinctions between form-based parameters in sign-language models have consequences for online processing. Vowels and consonants have different roles in speech recognition; similarly, it appears that movement, handshape, and location parameters contribute differentially to sign recognition.

    The aim of this study was to describe a new sonographic sign of bone fracture and to determine if it can be helpful in decreasing the number of missed fractures of the proximal humerus. Ultrasound (US) of the shoulder was performed in 57 consecutive patients with shoulder pain and/or disability following trauma. All cases were prospectively reviewed for the presence of a humeral fracture. Sonographic signs of fractures, with special emphasis on what was termed the 'double line sign' (DLS), were assessed. Plain radiography was considered the standard of reference and in equivocal cases magnetic resonance imaging (MRI). Twenty-eight patients had a tuberosity complex fracture, which were all detected at US examination. Sonographic features of a fracture were periosteal elevation, corticol bone discontinuity, step-off deformity or a combination of these findings. This study showed that in 26 (93%) patients an additional sonographic feature, a DLS, could be demonstrated. The DLS is a helpful and probably reliable sonographic sign to indicate a humeral fracture. High-spatial-resolution US substantially increases the detection of fractures of the proximal humerus and should be considered as an alternative diagnostic tool prior to computed tomography (CT), MRI and arthroscopy in patients with persisting shoulder pain and/or disability following trauma.

And a practical system is im plemented. The input of the system is Chinese text. The output of the system is "graphics person" who can gesticulate Chinese sign language accompanied by facial expression that corresponds to the Chinese text entered so as to realize automatic translation from Chinese text to Chinese sign language.

  12. Fast Drawing of Traffic Sign Using Mobile Mapping System

    Science.gov (United States)

    Yao, Q.; Tan, B.; Huang, Y.

    2016-06-01

    Traffic sign provides road users with the specified instruction and information to enhance traffic safety. Automatic detection of traffic sign is important for navigation, autonomous driving, transportation asset management, etc. With the advance of laser and imaging sensors, Mobile Mapping System (MMS) becomes widely used in transportation agencies to map the transportation infrastructure. Although many algorithms of traffic sign detection are developed in the literature, they are still a tradeoff between the detection speed and accuracy, especially for the large-scale mobile mapping of both the rural and urban roads. This paper is motivated to efficiently survey traffic signs while mapping the road network and the roadside landscape. Inspired by the manual delineation of traffic sign, a drawing strategy is proposed to quickly approximate the boundary of traffic sign. Both the shape and color prior of the traffic sign are simultaneously involved during the drawing process. The most common speed-limit sign circle and the statistic color model of traffic sign are studied in this paper. Anchor points of traffic sign edge are located with the local maxima of color and gradient difference. Starting with the anchor points, contour of traffic sign is drawn smartly along the most significant direction of color and intensity consistency. The drawing process is also constrained by the curvature feature of the traffic sign circle. The drawing of linear growth is discarded immediately if it fails to form an arc over some steps. The Kalman filter principle is adopted to predict the temporal context of traffic sign. Based on the estimated point,we can predict and double check the traffic sign in consecutive frames.The event probability of having a traffic sign over the consecutive observations is compared with the null hypothesis of no perceptible traffic sign. The temporally salient traffic sign is then detected statistically and automatically as the rare event of having a

    2003-12-01

    Chronic mercury poisoning is becoming a health concern because of extensive pollution of water and fish, and the increasing consumption of fish in the human diet. Mercury is extremely toxic to the body, especially the central nervous system, but diagnosis is difficult because of the lack of specific signs. A total of 11 patients were observed to have a nonpruritic or mildly pruritic discreet papular and papulovesicular eruption that correlated with high blood mercury levels. The mercury evidently came from increased seafood consumption. All of the patients improved when they were placed on either a seafood-free diet or chelation therapy. Physicians should suspect mercury poisoning in patients who eat a high-seafood diet who present with an asymptomatic or mildly pruritic papular or papulovesicular eruption.

    Hydrogen peroxide is a useful disinfectant that has achieved widespread utility in varied clinical settings. We report an epidemic of hydrogen peroxide enteritis that developed in seven patients in our gastrointestinal endoscopy unit during a 2-week period in early 1988. During endoscopy, using recently sterilized endoscopes that were flushed with 3% hydrogen peroxide after the glutaraldehyde cycle, instantaneous blanching (the "snow white" sign) and effervescence were noted on the mucosal surfaces when the water button was depressed. No patient subsequently suffered morbidity or mortality associated with this peroxide enteritis, and the biopsy specimens revealed nonspecific inflammation. The toxicity of hydrogen peroxide when used in enema form is reviewed, as well as the pathogenesis of peroxide enteritis.

    2013-01-01

    'Most habitable worlds in the cosmos will have no remotely detectable signs of life' is proposed as a biological hypothesis to be tested in studies of exoplanets. Habitable planets could be discovered elsewhere in the Universe, yet there are many hypothetical scenarios whereby the search for life on them could yield negative results. Scenarios for habitable worlds with no remotely detectable signatures of life include: planets that are habitable, but have no biosphere (Uninhabited Habitable Worlds); planets with life, but lacking any detectable surface signatures of that life (laboratory examples are provided) and planets with life, where the concentration of atmospheric gases produced or removed by biota are impossible to disentangle from abiotic processes because of the lack of detailed knowledge of planetary conditions (the 'problem of exoplanet thermodynamic uncertainty'). A rejection of the hypothesis would require that the origin of life usually occurs on habitable planets, that spectrally detectable pi...

Wearable monitoring systems can provide continuous physiological data, as well as better information regarding the general health of individuals. Thus, such vital-sign monitoring systems will reduce health-care costs by disease prevention and enhance the quality of life with disease management. In this paper, recent progress in non-invasive monitoring technologies for chronic disease management is reviewed. In particular, devices and techniques for monitoring blood pressure, blood glucose levels, cardiac activity and respiratory activity are discussed; in addition, on-body propagation issues for multiple sensors are presented.

    Hypertrophic cardiomyopathy is a relatively common genetic disorder and usually asymptomatic. However, approximately 25% of patients develop left ventricular outflow obstruction and can develop angina, syncope, or congestive heart failure. Initiation and titration of beta-blockade usually results in symptomatic improvement. Patients with medically refractory symptoms can see further symptomatic improvement and relief of obstruction with either surgical myectomy or alcohol septal ablation (ASA). Although surgical myectomy has been the gold standard, ASA has been shown in nonrandomized studies and a meta-analysis to be comparable. In patients undergoing ASA without a rest obstruction, the Brokenbrough-Braunwald-Morrow sign can be used to accurately determine the degree of left ventricular outflow tract (LVOT) obstruction prior to, during, and after ASA.

    Engineers, designers and architects often look to nature for inspiration. The research on 'natural constructions' is aiming at innovation and the improvement of architectural quality. The introduction of life sciences terminology in the context of architecture delivers new perspectives towards innovation in architecture and design. The investigation is focused on the analogies between nature and architecture. Apart from other principles that are found in living nature, an interpretation of the so-called 'signs of life', which characterize living systems, in architecture is presented. Selected architectural projects that have applied specific characteristics of life, whether on purpose or not, will show the state of development in this field and open up future challenges. The survey will include famous built architecture as well as students' design programs, which were carried out under supervision of the author at the Department of Design and Building Construction at the Vienna University of Technology.

    Data collected by the CMS detector of 13 TeV centre of mass proton-proton collisions, provided during run 2 of the LHC, constitutes an integrated luminosity of $12.9\\,\\mathrm{fb}^{-1}$. This provides a tool to probe a previously unmeasured process, double parton scattering (DPS) in same-sign WW. Leptonic decay to a muon and associated neutrino was selected for each W boson. In this manner complicated backgrounds were all but negated. A BDT was trained against the most kinematically similar background, and appropriate statistical measures were used to estimate the contribution of fake leptons from W+jets and, to a lesser extent, ttbar. An expected uncertainty on the signal of 52\\% was extracted, or $2 \\sigma$ significance. An in-progress analysis will determine a limit on the production cross section.

    Tomaszewski, Piotr

    2015-01-01

    The aim of this article is to describe a negative prefix, NEG-, in Polish Sign Language (PJM) which appears to be indigenous to the language. This is of interest given the relative rarity of prefixes in sign languages. Prefixed PJM signs were analyzed on the basis of both a corpus of texts signed by 15 deaf PJM users who are either native or near-native signers, and material including a specified range of prefixed signs as demonstrated by native signers in dictionary form (i.e. signs produced in isolation, not as part of phrases or sentences). In order to define the morphological rules behind prefixation on both the phonological and morphological levels, native PJM users were consulted for their expertise. The research results can enrich models for describing processes of grammaticalization in the context of the visual-gestural modality that forms the basis for sign language structure.

    ASL-LEX is a lexical database that catalogues information about nearly 1,000 signs in American Sign Language (ASL). It includes the following information: subjective frequency ratings from 25-31 deaf signers, iconicity ratings from 21-37 hearing non-signers, videoclip duration, sign length (onset and offset), grammatical class, and whether the sign is initialized, a fingerspelled loan sign, or a compound. Information about English translations is available for a subset of signs (e.g., alternate translations, translation consistency). In addition, phonological properties (sign type, selected fingers, flexion, major and minor location, and movement) were coded and used to generate sub-lexical frequency and neighborhood density estimates. ASL-LEX is intended for use by researchers, educators, and students who are interested in the properties of the ASL lexicon. An interactive website where the database can be browsed and downloaded is available at http://asl-lex.org .

    Full Text Available Let D = (V,A be a finite simple directed graph (shortly digraph in which d_D^{-}(vge 1 for all v in V . A function f : V ightarrow {-1,1} is called a signed total dominating function if sumlimits_{uin N_{-}^{v}{f(u}} ge 1 for each vertex vin V . A set {f_1,f_2, ..., f_g} of signed total dominating functions on D with the property that sumlimits_{i=1}^d{f_i(v}le 1 for each vin V(D, is called a signed total dominating family (of functions on D. The maximum number of functions in a signed total dominating family on D is the signed total domatic number of D, denoted by d_{st}(D. In this paper we present some bounds on the signed total domatic number and we determine the signed total domatic number of some classes of digraphs.

  8. Segmentation of British Sign Language (BSL): mind the gap!

    2015-01-01

    This study asks how users of British Sign Language (BSL) recognize individual signs in connected sign sequences. We examined whether this is achieved through modality-specific or modality-general segmentation procedures. A modality-specific feature of signed languages is that, during continuous signing, there are salient transitions between sign locations. We used the sign-spotting task to ask if and how BSL signers use these transitions in segmentation. A total of 96 real BSL signs were preceded by nonsense signs which were produced in either the target location or another location (with a small or large transition). Half of the transitions were within the same major body area (e.g., head) and half were across body areas (e.g., chest to hand). Deaf adult BSL users (a group of natives and early learners, and a group of late learners) spotted target signs best when there was a minimal transition and worst when there was a large transition. When location changes were present, both groups performed better when transitions were to a different body area than when they were within the same area. These findings suggest that transitions do not provide explicit sign-boundary cues in a modality-specific fashion. Instead, we argue that smaller transitions help recognition in a modality-general way by limiting lexical search to signs within location neighbourhoods, and that transitions across body areas also aid segmentation in a modality-general way, by providing a phonotactic cue to a sign boundary. We propose that sign segmentation is based on modality-general procedures which are core language-processing mechanisms.

  9. Medical diagnosis through semiotics. Giving meaning to the sign.

    Burnum, J F

    1993-11-01

    Physicians are engaged in incorporating quantitative methods for making clinical decisions into their practices. An acquaintance with semiotics, the doctrine of signs, may complement this project. A sign stands for something. We communicate indirectly through signs, and by interpreting what signs mean we make sense of our world and diagnose and understand our patients. Thus, through association and inference, we transform flowers into love, Othello into jealousy, and staring eyes into thyrotoxicosis. Characteristically in diagnosis, beginning with an unstable inference, we test and otherwise ask questions likely to produce signs that support (or discredit) our hypothesis. In a literary sense, we join with the author to clarify and rewrite the text; creative interpretation is the key. Diagnosis is concluded through narration, by the meaning that is revealed by telling the story of the patient. Diagnosis will succeed only to the extent that we respect the principles and caveats of sign interpretation. The sign is both the key to the unknown and the master impersonator. The sign and its meaning are usually not the same; meaning has to be inferred. Because interpretations are made subjectively, they are circumscribed by the experience and bias of the clinician. Moreover, the contexts in which the sign appears shape the meaning of the sign and may change it altogether.

  10. The role of syllables in sign language production.

    Baus, Cristina; Gutiérrez, Eva; Carreiras, Manuel

    2014-01-01

    The aim of the present study was to investigate the functional role of syllables in sign language and how the different phonological combinations influence sign production. Moreover, the influence of age of acquisition was evaluated. Deaf signers (native and non-native) of Catalan Signed Language (LSC) were asked in a picture-sign interference task to sign picture names while ignoring distractor-signs with which they shared two phonological parameters (out of three of the main sign parameters: Location, Movement, and Handshape). The results revealed a different impact of the three phonological combinations. While no effect was observed for the phonological combination Handshape-Location, the combination Handshape-Movement slowed down signing latencies, but only in the non-native group. A facilitatory effect was observed for both groups when pictures and distractors shared Location-Movement. Importantly, linguistic models have considered this phonological combination to be a privileged unit in the composition of signs, as syllables are in spoken languages. Thus, our results support the functional role of syllable units during phonological articulation in sign language production.

    Sign language recognition is a growing research area in the field of computer vision. A challenge within it is to model various signs, varying with time resolution, visual manual appearance, and so on. In this paper, we propose a discriminative exemplar coding (DEC) approach, as well as utilizing Kinect sensor, to model various signs. The proposed DEC method can be summarized as three steps. First, a quantity of class-specific candidate exemplars are learned from sign language videos in each sign category by considering their discrimination. Then, every video of all signs is described as a set of similarities between frames within it and the candidate exemplars. Instead of simply using a heuristic distance measure, the similarities are decided by a set of exemplar-based classifiers through the multiple instance learning, in which a positive (or negative) video is treated as a positive (or negative) bag and those frames similar to the given exemplar in Euclidean space as instances. Finally, we formulate the selection of the most discriminative exemplars into a framework and simultaneously produce a sign video classifier to recognize sign. To evaluate our method, we collect an American sign language dataset, which includes approximately 2000 phrases, while each phrase is captured by Kinect sensor with color, depth, and skeleton information. Experimental results on our dataset demonstrate the feasibility and effectiveness of the proposed approach for sign language recognition.

  12. Is the vacuum sign in the sacro-iliac joint a useful radiological sign of chondrocalcinosis?

    Shorter, A M; Burrows, D A; Cockshott, W P

    1984-01-01

    To test the contention that intra-articular gas is a radiological finding in chondrocalcinosis (CPPD), the prevalence of the sign was assessed in 44 patients with the disorder and compared to a control group of 272. We conclude that sacro-iliac gas is an inconstant finding occurring no more frequently in those with CPPD than in controls of the same age and sex. Consequently, this radiological finding is of limited clinical value.

    Do you get up in the morning and go online before getting your coffee? Do you sit down to meals with your mobile phone next to your plate? Do you get an awful feeling of complete disorientation and not knowing what to do with yourself when you disconnect from the Internet? As exaggerated as these actions may have seemed a few years ago, today they are familiar occurrences that are indeed the signs of our times.   “I connect, therefore I am” seems to be the new version of Descartes’ famous saying. The technological possibility of 24/7 worldwide connectivity is now an everyday fact of life and we all enjoy having knowledge at our fingertips and the ability to communicate across the globe quasi-instantaneously. In the work environment, this development has brought a flexibility and availability that has completely changed the way we work and interact with each other. This constant connectivity allows us to organise our lives differently, and we find ourselves worki...

  14. Statistical Signs of Social Influence on Suicides

    Melo, Hygor Piaget M.; Moreira, André A.; Batista, Élcio; Makse, Hernán A.; Andrade, José S.

    2014-09-01

    By treating the suicide as a social fact, Durkheim envisaged that suicide rates should be determined by the connections between people and society. Under the same framework, he considered that crime is bound up with the fundamental conditions of all social life. The social effect on the occurrence of homicides has been previously substantiated, and confirmed here, in terms of a superlinear scaling relation: by doubling the population of a Brazilian city results in an average increment of 135% in the number of homicides, rather than the expected isometric increase of 100%, as found, for example, for the mortality due to car crashes. Here we present statistical signs of the social influence on the suicide occurrence in cities. Differently from homicides (superlinear) and fatal events in car crashes (isometric), we find sublinear scaling behavior between the number of suicides and city population, with allometric power-law exponents, β = 0.84 +/- 0.02 and 0.87 +/- 0.01, for all cities in Brazil and US counties, respectively. Also for suicides in US, but using the Metropolitan Statistical Areas (MSAs), we obtain β = 0.88 +/- 0.01.

  15. Information and Signs: The Language of Images

    2010-03-01

    Full Text Available Since time immemorial, philosophers and scientists were searching for a “machine code” of the so-called Mentalese language capable of processing information at the pre-verbal, pre-expressive level. In this paper I suggest that human languages are only secondary to the system of primitive extra-linguistic signs which are hardwired in humans and serve as tools for understanding selves and others; and creating meanings for the multiplicity of experiences. The combinatorial semantics of the Mentalese may find its unorthodox expression in the semiotic system of Tarot images, the latter serving as the ”keys” to the encoded proto-mental information. The paper uses some works in systems theory by Erich Jantsch and Erwin Laszlo and relates Tarot images to the archetypes of the field of collective unconscious posited by Carl Jung. Our subconscious beliefs, hopes, fears and desires, of which we may be unaware at the subjective level, do have an objective compositional structure that may be laid down in front of our eyes in the format of pictorial semiotics representing the universe of affects, thoughts, and actions. Constructing imaginative narratives based on the expressive “language” of Tarot images enables us to anticipate possible consequences and consider a range of future options. The thesis advanced in this paper is also supported by the concept of informational universe of contemporary cosmology.

    1996-10-01

    The year 1996 marks the centenary of Babinski's description of the toe responses (normal and pathological) after stimulation of the sole of the foot. The upgoing toe response is normal in the 1st year of life and forms part of the flexion synergy of the leg, which had been known before 1896. Babinski also recognized the relation between the toe phenomenon (phénomène des orteils) in older children and adults and dysfunction of the pyramidal system. Neurologists became so fascinated by toe responses alone that many competing signs were proposed; most of these consisted of stimuli at other parts of the leg and were actually part of the same-but temporarily forgotten-flexion synergy. From 1910 to 1915 Marie and Foix and also Walshe re-emphasized this relationship and pointed out the analogy with the flexion reflex of the dog that had been extensively studied by Sherrington; the toe "extensors" shorten the leg and therefore they are flexors in a physiological sense. The normal (downward) toe response of the toes does not belong to a more complex movement, although Babinski originally believed this; it is a monosegmental skin reflex, akin to abdominal reflexes. Babinski correctly predicted that dysfunction of the pyramidal tract is not synonymous with a lesion, and that this dysfunction of the pyramidal system is necessary but not sufficient to produce a phénomène des orteils.

    Full Text Available T.S. Eliot’s query in The Waste Land, “Who is the third who walks always beside you?” may be said to sum up the hermeneutic situation of any language act, whether of sign production or interpretation. Whereas traditional topoi of expressionist aesthetics, such as the artist’s subjectivity, empirical psychology, truthfulness, intentionality, etc. have become irrelevant in the heteroglottic discourse of the most famous dirge on the decaying West, Eliot’s awareness of the matrical role of cultural semiosis allows us to place him among the founding fathers of semiotic aesthetics. The anagnorisis episode in The Waste Land is one of appropriate reading of the body of Christ through knowledge of the crucifixion scene and associated symbolism.Rooted in the insights of Charles Peirce Sanders and Charles Morris, and enlarged by post-war contributors, such as Roland Barthes, Umberto Eco, Michael B. Hardt, Richard Rudner, Foucault, Vattimo, Baudrillard and Deleuze, the semiotic, cultural materialist, or genetic approach  to art makes interpretation dependent on a mediating third (Peirce: the Interpretant, which is variously related to context, regime of signification, episteme, schemata, generic convention, structure of feeling, triangulation of desire ...

    Cockell, Charles S

    2014-04-28

    'Most habitable worlds in the cosmos will have no remotely detectable signs of life' is proposed as a biological hypothesis to be tested in the study of exoplanets. Habitable planets could be discovered elsewhere in the Universe, yet there are many hypothetical scenarios whereby the search for life on them could yield negative results. Scenarios for habitable worlds with no remotely detectable signatures of life include: planets that are habitable, but have no biosphere (Uninhabited Habitable Worlds); planets with life, but lacking any detectable surface signatures of that life (laboratory examples are provided); and planets with life, where the concentrations of atmospheric gases produced or removed by biota are impossible to disentangle from abiotic processes because of the lack of detailed knowledge of planetary conditions (the 'problem of exoplanet thermodynamic uncertainty'). A rejection of the hypothesis would require that the origin of life usually occurs on habitable planets, that spectrally detectable pigments and/or metabolisms that produce unequivocal biosignature gases (e.g. oxygenic photosynthesis) usually evolve and that the organisms that harbour them usually achieve a sufficient biomass to produce biosignatures detectable to alien astronomers.

    2013-11-01

    Full Text Available This paper provides a novel hand gesture recognition method to recognize 32 static signs of the Persian Sign Language (PSL alphabets. Accurate hand segmentation is the first and important step in sign language recognition systems. Here, we propose a method for hand segmentation that helps to build a better vision based sign language recognition system. The proposed method is based on YCbCr color space, single Gaussian model and Bayes rule. It detects region of hand in complex background and non-uniform illumination. Hand gesture features are extracted by radial distance and Fourier transform. Finally, the Euclidean distanceis used to compute the similarity between the input signs and all training feature vectors in the database. The system is tested on 480 posture images of the PSL, 15 images for each 32 signs. Experimental results show that our approach is capable to recognize all 32 PSL alphabets with 95.62% recognition rate.

    Full Text Available Traffic signs provide the driver various information for safe and efficient navigation. Automatic recognition of traffic signs is, therefore, important for automated driving or driver assistance systems.In this paper, a new and efficient traffic sign recognition system based on extracting diverse feature set, and applying mixture of experts'architecture on the extracted featuresis proposed.In the result part, the proposed approach is evaluated on the German traffic sign recognition and Grigorescu traffic signsbenchmark and high recognition rate is achieved.Comparison with some of the most related methods indicates that the proposed novel model yields excellent recognition rate in traffic sign recognition that is the recognition rate of 99.94% for the training set and 98.50% for the test set.In addition, experimental results have demonstrated our method robust in successful recognition of traffic signs even with variant lighting.

    2008-01-01

    The study attempted to identify characteristics of individual differences in sign language abilities among deaf children. Connections between sign language skills and rapid serial naming, hand motor skills, and early fluency were investigated. The sample consisted of 85 Finnish deaf children. Their first language was sign language. Simple correlations and multiple linear-regression analysis demonstrated the effect of early language development and serial hand movements on sign language abilities. Other significant factors were serial fingertapping and serial naming. Heterogeneity in poor sign language users was noted. Although identifying learning disorders in deaf children is complicated, developmental difficulties can be discovered by appropriate measurements. The study confirmed the results of earlier research demonstrating that the features of deaf and hearing children's learning resemble each other. Disorders in signed and spoken languages may have similar bases despite their different modalities.

    We describe observer-dependent sign inversions of the topological charges of vector field polarization singularities: C points (points of circular polarization), L points (points of linear polarization), and two virtually unknown singularities we call γ(C) and α(L) points. In all cases, the sign of the charge seen by an observer can change as she changes the direction from which she views the singularity. Analytic formulas are given for all C and all L point sign inversions.

  8. MIXED SIGNS IN THE SEMIOTICS OF ENGLISH EDUCATIONAL DISCOURSE

    Directory of Open Access Journals (Sweden)

    Goncharova Darya Anatolyevna

    2014-11-01

    Full Text Available The article deals with the linguosemiotic explication of nomination process in educational discourse by signs of different types – verbal, non-verbal, mixed. Verbal signs are presented by lexical units, nominating agents, clients, non/material resources, artifacts, processes, incentives and forms of pedagogical influence. The non-verbal signs include paralinguistic signs (gestures, facial expressions, postures of the participants of the educational process; color-semiotic signs (coloremas, in which the information-impacting vector is directed to a color indication of messages that is important for successful educational communication; visual elements representing traditional British values and concepts; sound signs, topographic signs, that add meaning to the overall significance of a mixed sign. In linguosemiotic system of educational discourse, the mixed signs form the most numerous group and are represented mainly by emblems, anthems and school songs of secondary schools. The author checks and verifies the hypothesis that the semiotics of the educational process in British secondary schools includes the extensive and complex system of mixed signs, which consist of two non-homogeneous parts – verbal and non-verbal – belonging to other sign systems rather than natural language and expressed via graphics, colors, music, etc. Linguistic analysis is applied to the study of the semiotic space of educational discourse. The article determines that in the context of educational communication, verbal, non-verbal and mixed signs form the unity of the linguistic and extralinguistic parameters, being in different relationships and presenting a multilayer intersection of lexical groups, graphic description, color schemes and music accompaniment.

    We empirical study the signs' property in the directed signed social networks of Slashdot and Epinions by using an reshuffled approach. Through calculating the entropy $S_{out}$ and the giant component $G$, we find an interesting 90/10 phenomenon: each individual labels his/her neighbors as friends with $90\\%$ or foes with $10\\%$ uniformly random from the macroscopic perspective. We also find that the entropy $S_{out}$ is suppressed by the non-randomness of labeling sign. Our present work can prove how do the randomness and the non-randomness coexist in human behavior of labeling signs, qualitatively.

    Pigment cells in the anterior vitreous (Shafer's sign) are known to be associated with retinal breaks. We sought to identify the reproducibility of Shafer's sign between different grades of ophthalmic staff. In all 47 patients were examined by a consultant vitreo-retinal surgeon, a senior house officer (SHO) and optician for Shafer's sign. Cohen's kappa for consultant vs SHO assessment of Shafer's sign was 0.55 while for consultant vs optician assessment, kappa was 0.28. Retinal tears were present in 63.8% of our series. Consultant assessment of Shafer's sign with fundoscopy findings, we found specificity to be 93.5% while sensitivity was 93.8%. Kappa for consultant assessment of Shafer's sign vs break presence was 0.86.Consultant and SHO assessment of Shafer's sign is of moderate agreement while optician assessment is fair. These results suggest a relationship between training and the assessment of Shafer's sign. We feel this study suggests caution in undue reliance on Shafer's sign particularly for inexperienced members of staff.

    A retrospective study was performed to determine the sensitivities of the pyramidal signs in patients with cervical myelopathy, focusing on those with increased signal intensity (ISI) in T2-weighted magnetic resonance imaging (MRI). The relationship between prevalence of the pyramidal signs and the severity of myelopathy was investigated. We reviewed the records of 275 patients with cervical myelopathy who underwent surgery. Of these, 143 patients were excluded from this study due to comorbidities that might complicate neurological findings. The MR images of the remaining 132 patients were evaluated in a blinded fashion. The neurological findings of 120 patients with ISI (90 men and 30 women; mean age 61 years) were reviewed for hyperreflexia (patellar tendon reflex), ankle clonus, Hoffmann reflex, and Babinski sign. To assess the severity of myelopathy, the motor function scores of the upper and lower extremities for cervical myelopathy set by the Japanese Orthopaedic Association (m-JOA score) were used. The most prevalent signs were hyperreflexia (94%), Hoffmann reflex (81%), Babinski sign (53%), and ankle clonus (35%). Babinski sign (P Babinski sign, and ankle clonus. The prevalence of the pyramidal signs correlated with increasing severity of myelopathy. Considering their low sensitivity in patients with mild disability, the pyramidal signs may have limited utility in early diagnosis of cervical myelopathy.

    2009-04-15

    Studies directly evaluating the reliability of the Risser sign are few in number, possess small sample sizes, and offer conflicting results. This study establishes the reliability of the Risser sign on a large sample size in an effort to provide clarification on the subject. Two years' worth of AP pelvis radiographs from patients age 8-20 were downloaded from our institution's digital imaging system. One hundred of these images were selected for inclusion by an independent reviewer whose goal was to capture a spread of radiographs that included all Risser stages. Risser grading occurred in two rounds. In each round, three examiners randomly reviewed the 100 radiographs on three different occasions. The full AP pelvis radiograph was graded in Round 1 while only the iliac apophysis was visible in Round 2. Kappa coefficients and their confidence bounds are reported to indicate intra- and inter-observer reliability. The contrast between the rates of agreement about Risser stages in Rounds 1 versus 2 was assessed by McNemar's test. The signed-rank test was used to evaluate differences in intra-observer values between rounds. Round 1 inter-observer kappa was 0.76. Round 2 inter-observer kappa was 0.51. In Round 1, 63 radiographs showed perfect agreement within the same Risser stage for all observations compared to 44 radiographs with perfect agreement within the same Risser stage in Round 2 (p=0.004). Round 1 intra-observer kappa values were 0.92, 0.86, and 0.88. Round 2 intra-observer kappa values were 0.91, 0.77, and 0.88. Intra-observer value differences between rounds were not significant for two observers (p=0.074, 0.061) but was significant for the third observer (p=0.002). The reliability of the Risser sign is acceptable and can be further improved when other markers of skeletal maturity on the pelvis radiograph are used to assist in grading. (orig.)

    Full Text Available Introduction: Subcutaneous manifestations of severe acute pancreatitis (Cullen’s sign, Gray- Turner’s sign, Fox’s sign, and Bryant’s sign are often discussed in journals and textbooks, but seldom observed. Although historically associated with acute pancreatitis, these clinical signs have been described in various other conditions associated with retroperitoneal hemorrhage. Case report: We describe the case of a 61-year-old male with no history of alcohol intake, who was admitted for epigastric pain, vomiting, and increasing serum amylase and lipase levels. Five days after admission, ecchymotic skin discoloration was noted over both flanks (Gray-Turner’s sign and the upper third of the thighs (Fox’s sign. Ten days later, he developed multiorgan failure and was transferred to the ICU for 5 days. Computed tomography revealed a large pancreatic fluid collection, which was subjected to EUS-guided drainage. Cholecystectomy was later performed for persistent obstructive jaundice. After more than 4 months of hospitalization, he died as a result of severe gastrointestinal bleeding. Discussion and conclusions: Skin manifestations of retroperitoneal hemorrhage in a patient with acute pancreatitis indicate a stormy disease course and poor prognosis. The severity of acute pancreatitis is currently estimated with validated scoring systems based on clinical, laboratory, and imaging findings. However, skin signs like the ones discussed above can represent a simple and inexpensive parameter for evaluating the severity and prognosis of this disease.

  5. Pavlovian sign-tracking model of alcohol abuse.

    Tomie, Arthur; Sharma, Nikyta

    2013-09-01

    While poorly controlled alcohol drinking is a prominent symptom of alcohol abuse, its environmental determinants remain poorly understood. The Sign-Tracking Model (STM), developed by Tomie and his associates, postulates that poorly controlled alcohol drinking is due to the development of signal-directed behaviors induced by Pavlovian sign-tracking procedures. In laboratory studies of animal learning, presentation of the lever (conditioned stimulus, CS) followed by the presentation of the food (unconditioned stimulus, US) induces sign-tracking conditioned response (CR) performance, wherein rats approach and contact, then express consummatory-like responses (i.e., licking, gnawing, and chewing) directed at the lever CS. The Pavlovian sign-tracking CR is an involuntary acquired reflexive response. It is poorly controlled and elicited by the presentation of the CS. STM proposes that poorly controlled alcohol drinking in humans may be due to repeated pairings of the alcohol sipper (e.g., cocktail glass) CS with alcohol's rewarding effects US, resulting in sign-tracking CR performance. The cocktail glass CS will elicit Pavlovian sign-tracking CR performance of reflexive and involuntary alcohol intake. This paper reviews evidence in the Pavlovian conditioning literature that in animals the positive contingency between the alcohol sipper CS and alcohol US induces sign-tracking of alcohol drinking. Also reviewed is evidence that in human beings alcohol drinking is a direct function of the positive contingency between a particular alcohol glassware CS and alcohol US. Implications of these findings for the Sign-Tracking Model (STM) are discussed.

    2006-06-15

    The purpose of our study is to demonstrate the uncovertebral mal-alignment as a reliable indirect sign of cervical facet joint dislocation. We examined the uncovertebral axial plane alignment of 12 patients with unilateral and bilateral cervical facet joint dislocation (UCFJD and BCFJD, respectively), comparing its frequency to the reverse hamburger bun sign on CT and MR axial images. Of the seven cases with BCFJD, five clearly demonstrated the diagnostic reverse facet joint hamburger bun sign on CT and MR images, but in two cases this sign was not detectable. In the five cases with UCFJD, four demonstrated the reverse hamburger bun sign on both CT and MRI. In one case the reverse hamburger bun sign was not seen adequately with either image modality, but the facet dislocation was identified on sagittal imaging. The uncovertebral mal-alignment was detected in all 12 cases. Normally, the two components of the uncovertebral joint enjoy a concentric relationship that in the axial plane is reminiscent of the relationship of headphones with the wearer's head. We name this appearance the 'headphones' sign. Radiologists should be aware of the headphones sign as a reliable indicator of facet joint dislocation on axial imaging used in the assessment of cervical spine injuries. (orig.)

    The "sagging rope" sign is a radiopaque line seen on radiographs of hips with Perthes disease. The main purpose of this study was to determine the incidence, cause, and importance of this sign in achondroplasia and to reveal how it differs from in Perthes disease. Serial radiograms, along with two- and three-dimensional CT images were studied in 42 patients with achondroplasia. The sign was observed bilaterally in all patients. Evaluation of CT images revealed spherical heads with the presence of circumferential overhang in all hips. This circumferential overhang seen on three-dimensional CT images corresponded to the sagging rope sign on plain radiographs. The presence of the sagging rope sign in bilateral hips is a characteristic feature of achondroplasia. It usually appears before epiphyseal closure. Its cause, incidence, and nature differ from in Perthes disease, and its presence does not carry a negative prognosis in achondroplasia.

    1999-01-01

    This article considers the impact of Vygotsky on the education of deaf children in Russia and is a translation/adaptation of an article currently being published in Defektologiia. While Vygotsky perceived sign language as limited in some aspects nevertheless, he always considered that it had a role in education of deaf pupils. He believed that sign language should not be 'treated like an the enemy' and said that 'bilingualism of def people is an objective reality'. However, sign language was banned from Russian schools following a conference decision in 1938. The changing political climate in Russia has lead to the reevaluation of many aspects of life, including approaches to education, and to a reassessment of Vygotsky's ideas and an appreciation of their continuing relevance. Among other things, this has resulted in a reevaluation of the role of sign language for deaf pupils and an emerging interest in sign bilingualism.

  13. On Nonnegative Signed Domination in Graphs and its Algorithmic Complexity

    Directory of Open Access Journals (Sweden)

    2013-02-01

    Full Text Available Let G = (V, E be a simple graph with vertex set V and edge set E. A function f from V to a set {-1, 1} is said to be a nonnegative signed dominating function (NNSDF if the sum of its function values over any closed neighborhood is at least zero. The weight of f is the sum of function values of vertices in V. The nonnegative signed domination number for a graph G equals the minimum weight of a nonnegative signed dominating function of G. In this paper, exact values are found for cycles, stars, wheels, spiders and complete equally bipartite graphs and we present some lower bounds for nonnegative signed domination number in terms of the order and the maximum and minimum degree. Fothermore, we show that the decision problem corresponding to the problem of computing the nonnegative signed domination number is NP-complete.

    2013-05-01

    Sign Language Recognition has emerged as one of the important area of research in Computer Vision. The difficulty faced by the researchers is that the instances of signs vary with both motion and appearance. Thus, in this paper a novel approach for recognizing various alphabets of Indian Sign Language is proposed where continuous video sequences of the signs have been considered. The proposed system comprises of three stages: Preprocessing stage, Feature Extraction and Classification. Preprocessing stage includes skin filtering, histogram matching. Eigen values and Eigen Vectors were considered for feature extraction stage and finally Eigen value weighted Euclidean distance is used to recognize the sign. It deals with bare hands, thus allowing the user to interact with the system in natural way. We have considered 24 different alphabets in the video sequences and attained a success rate of 96.25%.

    Hashimoto Kimio

    2010-11-01

    Full Text Available Abstract Background The reversed halo sign may sometimes be seen in patients with cryptogenic organizing pneumonia, but is rarely associated with other diseases. Case presentation We present a case study of a 32-year-old male patient with acquired immunodeficiency syndrome, who had previously been treated with chemotherapy for non-Hodgkin's lymphoma. A chest X-ray showed bilateral patchy infiltrates. High-resolution computed tomography revealed the reversed halo sign in both upper lobes. The patient was diagnosed with pneumocystis pneumonia, which was successfully treated with sulfamethoxazole trimethoprim; the reversed halo sign disappeared, leaving cystic lesions. Cases such as this one are rare, but show that the reversed halo sign may occur in patients who do not have cryptogenic organizing pneumonia. Conclusion Physicians can avoid making an incorrect diagnosis and prescribing the wrong treatment by carefully evaluating all clinical criteria rather than assuming that the reversed halo sign only occurs with cryptogenic organizing pneumonia.

    Full Text Available Abstract Background Awareness of the danger signs of obstetric complications is the essential first step in accepting appropriate and timely referral to obstetric and newborn care. The objectives of this study were to assess women's awareness of danger signs of obstetric complications and to identify associated factors in a rural district in Tanzania. Methods A total of 1118 women who had been pregnant in the past two years were interviewed. A list of medically recognized potentially life threatening obstetric signs was obtained from the responses given. Chi- square test was used to determine associations between categorical variables and multivariate logistic regression analysis was used to identify factors associated with awareness of obstetric danger signs. Results More than 98% of the women attended antenatal care at least once. Half of the women knew at least one obstetric danger sign. The percentage of women who knew at least one danger sign during pregnancy was 26%, during delivery 23% and after delivery 40%. Few women knew three or more danger signs. According to multivariate logistic regression analysis having secondary education or more increased the likelihood of awareness of obstetric danger signs six-fold (OR = 5.8; 95% CI: 1.8–19 in comparison with no education at all. The likelihood to have more awareness increased significantly by increasing age of the mother, number of deliveries, number of antenatal visits, whether the delivery took place at a health institution and whether the mother was informed of having a risks/complications during antenatal care. Conclusion Women had low awareness of danger signs of obstetric complications. We recommend the following in order to increase awareness of danger signs of obstetrical complications: to improve quality of counseling and involving other family members in antenatal and postnatal care, to use radio messages and educational sessions targeting the whole community and to intensify

Although state officials have trumpeted this initiative as a national model that other states are copying, they announced in November 2002 that they were radically changing it. The changes included halting the state's national recruitment efforts and replacing the seven-week, fast-track training program designed by the New Teacher Project with year-long programs to be designed by three of the state's education schools. Even though the state spent more than $50,000 recruiting individuals from states outside the Northeast over the first four program years, it garnered just seven bonus recipients from the non-Northeast states its recruiters visited, only four of whom were still teaching in Fall 2002. The state did, however, generate a substantial number of applicants in each program year (ranging from 783 to nearly 950, most of whom came from Massachusetts or nearby states. Contrary to state officials' claims, though, it appears that many of these individuals had substantial prior educational experience. Although officials stated that all bonus teachers would go to 13 designated high-need urban districts, the state has never met this commitment, sending fewer bonus teachers to these districts in each of the first three years of the program. The state has lost a high percentage of its bonus teachers to attrition particularly in state-designated, high-need districts. These attrition rates are substantially higher than comparable national rates. Although the state has portrayed the Bonus and MINT programs, combined, as highly successful, officials exaggerated many of the purported positive outcomes. On the positive side, independent survey data (Churchill et al., 2002 indicated that principals

  20. Signing Earth Science: Accommodations for Students Who Are Deaf or Hard of Hearing and Whose First Language Is Sign

    2014-12-01

    TERC and Vcom3D used the SigningAvatar® accessibility software to research and develop a Signing Earth Science Dictionary (SESD) of approximately 750 standards-based Earth science terms for high school students who are deaf and hard of hearing and whose first language is sign. The partners also evaluated the extent to which use of the SESD furthers understanding of Earth science content, command of the language of Earth science, and the ability to study Earth science independently. Disseminated as a Web-based version and App, the SESD is intended to serve the ~36,000 grade 9-12 students who are deaf or hard of hearing and whose first language is sign, the majority of whom leave high school reading at the fifth grade or below. It is also intended for teachers and interpreters who interact with members of this population and professionals working with Earth science education programs during field trips, internships etc. The signed SESD terms have been incorporated into a Mobile Communication App (MCA). This App for Androids is intended to facilitate communication between English speakers and persons who communicate in American Sign Language (ASL) or Signed English. It can translate words, phrases, or whole sentences from written or spoken English to animated signing. It can also fingerspell proper names and other words for which there are no signs. For our presentation, we will demonstrate the interactive features of the SigningAvatar® accessibility software that support the three principles of Universal Design for Learning (UDL) and have been incorporated into the SESD and MCA. Results from national field-tests will provide insight into the SESD's and MCA's potential applicability beyond grade 12 as accommodations that can be used for accessing the vocabulary deaf and hard of hearing students need for study of the geosciences and for facilitating communication about content. This work was funded in part by grants from NSF and the U.S. Department of Education.

    This study investigates the conventionalization of mouth actions in Australian Sign Language. Signed languages were once thought of as simply manual languages because the hands produce the signs which individually and in groups are the symbolic units most easily equated with the words, phrases and clauses of spoken languages. However, it has long been acknowledged that non-manual activity, such as movements of the body, head and the face play a very important role. In this context, mouth actions that occur while communicating in signed languages have posed a number of questions for linguists: are the silent mouthings of spoken language words simply borrowings from the respective majority community spoken language(s)? Are those mouth actions that are not silent mouthings of spoken words conventionalized linguistic units proper to each signed language, culturally linked semi-conventional gestural units shared by signers with members of the majority speaking community, or even gestures and expressions common to all humans? We use a corpus-based approach to gather evidence of the extent of the use of mouth actions in naturalistic Australian Sign Language-making comparisons with other signed languages where data is available--and the form/meaning pairings that these mouth actions instantiate.

    Mycetoma is a slowly progressive localised, granulomatous, subcutaneous tissue infection common among adult males aged 20 - 50 years. The causing agents include both bacteria (actinomycetoma) and fungi (eumycetoma). This chronic infection was described in literature as Madura foot and eventually mycetoma, due to its etiology. Early clinical diagnosis before the appearance of sinuses and grains (aggregates of organism surrounded by granulation tissue, which are discharged from the draining sinuses) is difficult. Early diagnosis is important due to the therapeutic implications. Although biopsy and microbiological cultures provide definitive diagnosis. Delay in diagnosis may lead to amputation of the affected part. The recently described "dot-in-circle" sign on magnetic resonance imaging (MRI) is easy to recognise and highly specific. We present a case of histologically proven mycetoma with characteristic MRI features.

    Traffic sign detection and recognition (TSDR) has drawn considerable attention on developing intelligent transportation systems (ITS) and autonomous vehicle driving systems (AVDS) since 1980's. Unlikely to the general TSDR systems that deal with real-time images captured by the in-vehicle cameras, this research aims on developing techniques for detecting, extracting, and positioning of traffic signs from Google Street View (GSV) images along user-selected routes for low-cost, volumetric and quick establishment of the traffic sign infrastructural database that may be associated with Google Maps. The framework and techniques employed in the proposed system are described.

    2003-02-01

    Green Light for World's Most Powerful Radio Observatory On February 25, 2003, the European Southern Observatory (ESO) and the US National Science Foundation (NSF) are signing a historic agreement to construct and operate the world's largest and most powerful radio telescope, operating at millimeter and sub-millimeter wavelength. The Director General of ESO, Dr. Catherine Cesarsky, and the Director of the NSF, Dr. Rita Colwell, act for their respective organizations. Known as the Atacama Large Millimeter Array (ALMA), the future facility will encompass sixty-four interconnected 12-meter antennae at a unique, high-altitude site at Chajnantor in the Atacama region of northern Chile. ALMA is a joint project between Europe and North America. In Europe, ESO is leading on behalf of its ten member countries and Spain. In North America, the NSF also acts for the National Research Council of Canada and executes the project through the National Radio Astronomy Observatory (NRAO) operated by Associated Universities, Inc. (AUI). The conclusion of the ESO-NSF Agreement now gives the final green light for the ALMA project. The total cost of approximately 650 million Euro (or US Dollars) is shared equally between the two partners. Dr. Cesarsky is excited: "This agreement signifies the start of a great project of contemporary astronomy and astrophysics. Representing Europe, and in collaboration with many laboratories and institutes on this continent, we together look forward towards wonderful research projects. With ALMA we may learn how the earliest galaxies in the Universe really looked like, to mention but one of the many eagerly awaited opportunities with this marvellous facility". "With this agreement, we usher in a new age of research in astronomy" says Dr. Colwell. "By working together in this truly global partnership, the international astronomy community will be able to ensure the research capabilities needed to meet the long-term demands of our scientific enterprise, and

    Alexandru, Andrei; Bedaque, Paulo F; Ridgway, Gregory W; Warrington, Neill C

    2015-01-01

    We point out that Monte Carlo simulations of theories with severe sign problems can be profitably performed over manifolds in complex space different from the one with fixed imaginary part of the action. We describe a family of such manifolds that interpolate between the tangent space at one critical point, where the sign problem is milder compared to the real plane but in some cases still severe, and the union of relevant thimbles, where the sign problem is mild but a multimodal distribution function complicates the Monte Carlo sampling. We exemplify this approach using a simple 0 + 1 dimensional fermion model previously used on sign problem studies and show that it can solve the model for some parameter values where a solution using Lefshetz thimbles was elusive.

    2011-10-01

    Full Text Available In redundant representations, addition can be carried out in a constant time independent of the word length of the operands. Adder forms a fundamental building block in almost majority of VLSI designs. A hybrid adder can add an unsigned number to a signed-digit number and hence their efficient performance greatly determinesthe quality of the final output of the concerned circuit. In this paper we designed and compared the speed of adders by reducing the carry propagation time with the help of combined effect of improved architectures of adders and signed digit representation of number systems. The key idea is to draw out a compromise between execution time of fast adding process and area available which is often very limited. In this paper we also tried to verify the various algorithms of signed digit and hybrid signed digit adders.

    2014-07-01

    Lung ultrasound has emerged as a rapid and accurate screening tool for pneumothorax. The lung point sign, a sonographic representation of the point on the chest wall where the pleural layers re-adhere, is 100% specific to confirm the diagnosis. Double lung point sign for a single pneumothorax is extremely unusual and has only been reported twice in the literature. A 49-year-old woman was transported to the emergency department (ED) intubated and sedated with severe head injury. She remained hemodynamically stable without respiratory compromise throughout her ED course. Chest computed tomography was notable for an anterior left pneumothorax with underlying pulmonary contusion. Bedside ultrasound of this region revealed a double lung point sign. Our case report is the first to confirm association of the double lung point sign with a single pneumothorax on corresponding computed tomographic imaging.

    Projection Monte Carlo calculations of lattice Chiral Effective Field Theory suffer from sign oscillations to a varying degree dependent on the number of protons and neutrons. Hence, such studies have hitherto been concentrated on nuclei with equal numbers of protons and neutrons, and especially on the alpha nuclei where the sign oscillations are smallest. We now introduce the technique of "symmetry-sign extrapolation" which allows us to use the approximate Wigner SU(4) symmetry of the nuclear interaction to control the sign oscillations without introducing unknown systematic errors. We benchmark this method by calculating the ground-state energies of the $^{12}$C, $^6$He and $^6$Be nuclei, and discuss its potential for studies of neutron-rich halo nuclei and asymmetric nuclear matter.

    The BSL Glossary Project, run by the Scottish Sensory Centre at the University of Edinburgh focuses on developing scientific terminology in British Sign Language for use in the primary, secondary and tertiary education of deaf and hard of hearing students within the UK. Thus far, the project has developed 850 new signs and definitions covering Chemistry, Physics, Biology, Astronomy and Mathematics. The project has also translated examinations into BSL for students across Scotland. The current phase of the project has focused on developing terminology for Geography and Geology subjects. More than 189 new signs have been developed in these subjects including weather, rivers, maps, natural hazards and Geographical Information Systems. The signs were developed by a focus group with expertise in Geography and Geology, Chemistry, Ecology, BSL Linguistics and Deaf Education all of whom are deaf fluent BSL users.

    1989-09-01

    Reliability and stability of neurological "subtle" ("soft") signs were assessed in 54 psychiatric patients and 25 normal children, aged 5-17 years, using the revised Neurological Examination for Subtle Signs (NESS). Acceptable interrater reliability (kappa greater than or equal to 0.50, or intraclass correlation coefficient greater than or equal to 0.70) was found for 40 of the 64 items tested. Test-retest reliability at 2 weeks was unsatisfactory for most of the categorically scored items, including some "classic" subtle signs such as overflows or dysrhythmias. Continuous items, such as time needed to perform 20 consecutive movements, remained mostly stable at retest. A practicing effect was evident only in the graphesthesia test. Overall internal consistency was good (Cronbach's alpha = 0.74). Given the poor stability of overflows and dysrhythmias, researchers and clinicians should rely more on subtle signs that can be assessed on continuous scales.

  5. Emotional Strategies as Catalysts of Cooperation in Signed Networks

    CERN Document Server

    Righi, Simone

    2014-01-01

    The evolution of unconditional cooperation is one of the key problems of science. We suggest a new solution to this puzzle. We introduce an evolutionary model where agents play the Prisoner's Dilemma on signed networks and the topology is allowed to co-evolve with relational signs as well as with agent strategies. The introduction of conditional strategies, exploiting the emotional content embedded in network signs, can act as catalysts and create favorable conditions for the spread of unconditional cooperation. In line with the literature, evidence is found that evolution of unconditional cooperation is most likely to occur in networks with relatively high chances of rewiring and low likelihood of strategy adoption. However, while some rewiring enhances cooperation too much is shown to limit its diffusion. Furthermore, unlike the non signed network case, cooperation becomes more prevalent in denser topologies.

    We present a case of 50 year old male patient with coexistence of Pneumothorax and Chilaiditi sign. Chilaiditi sign is an incidental radiographic finding of a usually asymptomatic condition in which a part of intestine is located between the liver and diaphragm; however, the term“Chilaiditi syndrome”is used for symptomatic hepatodiaphragmatic interposition. The patient had no symptoms of abdominal pain, constipation, diarrhea, or emesis. Incidentally, Chilaiditi sign was diagnosed on chest radiography. Pneumothorax is defined as air in the pleural space. Pneumothoraces are classified as spontaneous or traumatic. Spontaneous pneumothorax is labelled as primary when no underlying lung disease is present, or secondary, when it is associated with pre-existing lung disease. Our case is the rare in the literature indicating the coexistence of Chilaiditi sign and pneumothorax.

    The asterisk sign is a stellate density, which is seen normally in the femoral head on computed tomography. It is due to the demonstration of the trabeculae in the femoral head. In adult ischaemic necrosis of the femoral head, there are characteristic changes in the asterisk sign at an early stage, even before there is collapse of the head. The changes are described and the indications for performing CT of the hip for diagnosing adult ischaemic necrosis are discussed.

    The colographic appearance of intussusception is variously described as a claw sign, pincer defect, shouldering effect, and coiled-spring pattern. This report adds a new radiographic sign to the list. An end-on view of an intussusception on barium enema shows a ring of contrast resembling a solar eclipse. Familiarity with this bizarre appearance is desirable, lest it may be mistaken for spillage of barium due to a colonic perforation.

    Highlights: • The main CT signs associated with basilar artery occlusion were analyzed. • CT sign of acute ischemic lesion is significantly associated with a bad outcome. • The site of the basilar artery occlusion is not associated to the patients’ outcome. - Abstract: Purpose: To determine the computed tomography (CT) signs that are predictive of the clinical outcome of basilar artery occlusion (BAO). Materials and methods: The study population consisted in 37 patients (14 women, 23 men, mean age: 63 years), admitted with onset of neurological deficit, starting 1–72 h prior to admission, who were diagnosed with BAO on the basis of a CT examination with intravenous contrast agent. The following signs were collected on CT scans performed on admission: clot density on noncontrast images, clot length, and clot location, as well as the presence of acute ischemic lesions. The results were compared against the modified Rankin Scale (mRS) score of patients at 3 months, favorable clinical outcome being defined as a mRS score ≤3. Results: The clinical outcome was favorable in 13 (35%) of the 37 patients and unfavorable in 24 (65%). Signs of acute ischemia were visible in 13 of the 24 patients with unfavorable outcome but in none of the 13 patients with favorable outcome (p < 0.001). None of the other CT signs analyzed were significantly correlated with clinical prognosis. Conclusion: Of all the CT signs analyzed, only the presence of signs of acute ischemia on the admission CT of patients with BAO was associated with poor prognosis.

    The sagging rope sign is the term used to describe the radiographic appearances which sometimes occur after Perthes' disease. It is severe examples of that disease and indicates damage to the growth plate with a marked metaphysial reaction. The same appearance follows severe epiphysitis after forcible reduction of a congenitally dislocated hip, and certain rare epiphysial dysplasias. The origin and significance of the sign are discussed.

    2010-01-01

    Evidence from sign language strongly supports three positions: (1) language is a coherent system with universal properties; (2) sign languages diverge from spoken languages in some aspects of their structure; and (3) domain-external factors can be identified that account for some crucial aspects of language structure -- uniform and diverse -- in both modalities. Assuming that any of these positions excludes the others defeats the purpose of the enterprise. PMID:21076645

    Studies of spoken and written language suggest that the perception of sentences engages the left anterior and posterior temporal cortex and the left inferior frontal gyrus to a greater extent than non-sententially structured material, such as word lists. This study sought to determine whether the same is true when the language is gestural and perceived visually. Regional neural activity was measured using functional MRI while Deaf and hearing native signers of British Sign Language (BSL) detected semantic anomalies in well-formed BSL sentences and when they detected nonsense signs in lists of unconnected BSL signs. Processing BSL sentences, when contrasted with signed lists, was reliably associated with greater activation in the posterior portions of the left middle and superior temporal gyri and in the left inferior frontal cortex, but not in the anterior temporal cortex, which was activated to a similar extent whether lists or sentences were processed. Further support for the specificity of these areas for processing the linguistic-rather than visuospatial-features of signed sentences came from a contrast of hearing native signers and hearing sign-naïve participants. Hearing signers recruited the left posterior temporal and inferior frontal regions during BSL sentence processing to a greater extent than hearing non-signers. These data suggest that these left perisylvian regions are differentially associated with sentence processing, whatever the modality of the linguistic input.

    Mathematical concepts and tools have an important role in physics. Faculties want students to think critically about mathematics and the underlying fundamental concepts, rather than simply memorizing a series of equations and answers. The equals sign - ubiquitous in problem solving - carries different conceptual meaning depending on how it is used; this meaning is deeply tied to cultural practices in problem solving in physics. We use symbolic forms to investigate the conceptual and cultural meanings of the equals sign across physics contexts. We built and validated a rubric to classify the ways that physics students use the equals sign in their written work. Our categories are causality, assignments, definitional, balancing, and just math. We analyze students' use of the equals sign in their written homework and exam solutions in an upper-division electrostatics course. We correlate the kinds of equal signs within problem solutions with the difficulty of the problem. We compare they ways students use the equals sign to their course lectures and textbook.

    Astrology is no longer regarded as a science by many, because its claims are almost impossible to test empirically in controlled laboratory conditions and it can not meet the scientific need to be reproducible. However, the majority of those who read their 'star signs' can identify aspects of their personality in what they read and it is possible that this may influence their attitudes and actions. The literature has neglected astrological signs as a possible predictor of suicide ideation. To see whether astrological birth signs are associated with suicide and the method used, data was collected from the Public Health Department in North Cheshire representing all the Cheshire Coroner's verdicts of suicide, and open verdicts, in all deceased aged 60 and above between 1989 and 2000. The observed occurrence of deaths due to natural causes, and suicide, in relation to birth signs did not differ significantly from what would be expected from chance. However, the distribution of suicide by hanging appeared significantly higher in those with a birth sign of Virgo and lowest in Sagittarius and Scorpio. The distribution of violent and non-violent suicides in relation to star signs showed higher occurences of violent death in persons born in the summer months.

    PSYCHOLINGUISTIC THEORIES HAVE PREDOMINANTLY BEEN BUILT UPON DATA FROM SPOKEN LANGUAGE, WHICH LEAVES OPEN THE QUESTION: How many of the conclusions truly reflect language-general principles as opposed to modality-specific ones? We take a step toward answering this question in the domain of lexical access in recognition by asking whether a single cognitive architecture might explain diverse behavioral patterns in signed and spoken language. Chen and Mirman (2012) presented a computational model of word processing that unified opposite effects of neighborhood density in speech production, perception, and written word recognition. Neighborhood density effects in sign language also vary depending on whether the neighbors share the same handshape or location. We present a spreading activation architecture that borrows the principles proposed by Chen and Mirman (2012), and show that if this architecture is elaborated to incorporate relatively minor facts about either (1) the time course of sign perception or (2) the frequency of sub-lexical units in sign languages, it produces data that match the experimental findings from sign languages. This work serves as a proof of concept that a single cognitive architecture could underlie both sign and word recognition.

    Full Text Available Traffic guide signs are effective only when they are clearly recognized by drivers. Three experiments were conducted in this study. In the first, the influence factors of guide sign recognition were studied. This study investigated 11 main factors with a convenience sample of drivers from Nanjing city in China. Weights of different influence factors were obtained through analytic hierarchy process (AHP. The results showed that the setting position, occlusion degree, and character size of guide sign had the most significant influence on the guide sign recognition, while other factors were less important. In the second stage, an evaluation model of guide sign recognition was developed based on weights of different factors. Four equations were presented to calculate the comprehensive score of guide sign, and the level of recognition was divided into five grades according to the comprehensive score. At last, a typical case in Nanjing was studied to verify the rationality and reliability of the evaluation model. Results from the real application indicate that the method had good applicability and can be used by traffic engineers.

    In real traffic scenes, the quality of captured images are generally low due to some factors such as lighting conditions, and occlusion on. All of these factors are challengeable for automated recognition algorithms of traffic signs. Deep learning has provided a new way to solve this kind of problems recently. The deep network can automatically learn features from a large number of data samples and obtain an excellent recognition performance. We therefore approach this task of recognition of traffic signs as a general vision problem, with few assumptions related to road signs. We propose a model of Convolutional Neural Network (CNN) and apply the model to the task of traffic signs recognition. The proposed model adopts deep CNN as the supervised learning model, directly takes the collected traffic signs image as the input, alternates the convolutional layer and subsampling layer, and automatically extracts the features for the recognition of the traffic signs images. The proposed model includes an input layer, three convolutional layers, three subsampling layers, a fully-connected layer, and an output layer. To validate the proposed model, the experiments are implemented using the public dataset of China competition of fuzzy image processing. Experimental results show that the proposed model produces a recognition accuracy of 99.01 % on the training dataset, and yield a record of 92% on the preliminary contest within the fourth best.

    Iconicity is a property that pervades the lexicon of many sign languages, including American Sign Language (ASL). Iconic signs exhibit a motivated, nonarbitrary mapping between the form of the sign and its meaning. We investigated whether iconicity enhances semantic priming effects for ASL and whether iconic signs are recognized more quickly than…

    The American Sign Language Comprehension Test (ASL-CT) is a 30-item multiple-choice test that measures ASL receptive skills and is administered through a website. This article describes the development and psychometric properties of the test based on a sample of 80 college students including deaf native signers, hearing native signers, deaf non-native signers, and hearing ASL students. The results revealed that the ASL-CT has good internal reliability (α = 0.834). Discriminant validity was established by demonstrating that deaf native signers performed significantly better than deaf non-native signers and hearing native signers. Concurrent validity was established by demonstrating that test results positively correlated with another measure of ASL ability (r = .715) and that hearing ASL students' performance positively correlated with the level of ASL courses they were taking (r = .726). Researchers can use the ASL-CT to characterize an individual's ASL comprehension skills, to establish a minimal skill level as an inclusion criterion for a study, to group study participants by ASL skill (e.g., proficient vs. nonproficient), or to provide a measure of ASL skill as a dependent variable.

    Identification of constituent components of each sign gesture can be beneficial to the improved performance of sign language recognition (SLR), especially for large-vocabulary SLR systems. Aiming at developing such a system using portable accelerometer (ACC) and surface electromyographic (sEMG) sensors, we propose a framework for automatic Chinese SLR at the component level. In the proposed framework, data segmentation, as an important preprocessing operation, is performed to divide a continuous sign language sentence into subword segments. Based on the features extracted from ACC and sEMG data, three basic components of sign subwords, namely the hand shape, orientation, and movement, are further modeled and the corresponding component classifiers are learned. At the decision level, a sequence of subwords can be recognized by fusing the likelihoods at the component level. The overall classification accuracy of 96.5% for a vocabulary of 120 signs and 86.7% for 200 sentences demonstrate the feasibility of interpreting sign components from ACC and sEMG data and clearly show the superior recognition performance of the proposed method when compared with the previous SLR method at the subword level. The proposed method seems promising for implementing large-vocabulary portable SLR systems.

    Objective To review the recent developments in and research into binding receptors of hepatitis C virus (HCV) and especially the role of dendritic cell-specitic adhesion receptor (DC-SIGN) in HCV.Data sources Both Chinese- and English-languge literature was searched using MEDLINE (2000-2003) and the databank of Chinese-language literature (2000-2003).Study selection Relevant articles on DC-SIGN and HCV binding receptors in recent domestic and foreign literature were selected.Data extraction Data were mainly extracted from 40 articles which are listed in the references section of this review. Results DC-SIGN, a dendritic cell-specific adhesion receptor and a type Ⅱ transmembrane mannose-binding C-type lectin, is very important in the function of dendritic cells (DC), both in mediating na(I)ve T cell interactions through ICAM-3 and as a rolling receptor that mediates the DC-specific ICAM-2-dependent migration processes-It can be used by HCV and other viral and bacterial pathogens including human immunodeficiency virus (HIV), Ebola virus, CMV and Mycobacterium tuberculosis- to facilitate infection. Both DC-SIGN and DC-SIGNR can act either in cis, by concentrating virus on target cells, or in trans, by transmission of bound virus to a target cell expressing appropriate entry receptors. Recent report showed that DC-S IGN not only plays a role in entry into DC, HCV E2 interaction with DC-SIGN might also be detrimental to the interaction of DC with T cells during antigen presentation.Conclusions DC-SIGNs are high-affinity binding receptors for HCV.The clinical strategies that target DC-SIGN may be successful in restricting HCV dissemination and pathogenesis as well as directing the migration of DCs to manipulate appropriate immune responses in autoimmunity and tumorigenic situations.

    Full Text Available Abstract Background As there is limited information about the clinical signs of BSE and scrapie in goats, studies were conducted to describe the clinical progression of scrapie and BSE in goats and to evaluate a short clinical protocol for its use in detecting scrapie-affected goats in two herds with previously confirmed scrapie cases. Clinical assessments were carried out in five goats intracerebrally infected with the BSE agent as well as five reported scrapie suspects and 346 goats subject to cull from the two herds, 24 of which were retained for further monitoring. The brain and selected lymphoid tissue were examined by postmortem tests for disease confirmation. Results The sensitivity and specificity of the short clinical protocol in detecting a scrapie case in the scrapie-affected herds was 3.9% and 99.6%, respectively, based on the presence of tremor, positive scratch test, extensive hair loss, ataxia and absent menace response. All BSE- and scrapie-affected goats displayed abnormalities in sensation (over-reactivity to external stimuli, startle responses, pruritus, absent menace response and movement (ataxia, tremor, postural deficits at an advanced clinical stage but the first detectable sign associated with scrapie or BSE could vary between animals. Signs of pruritus were not always present despite similar prion protein genotypes. Clinical signs of scrapie were also displayed by two scrapie cases that presented with detectable disease-associated prion protein only in lymphoid tissues. Conclusions BSE and scrapie may present as pruritic and non-pruritic forms in goats. Signs assessed for the clinical diagnosis of scrapie or BSE in goats should include postural and gait abnormalities, pruritus and visual impairment. However, many scrapie cases will be missed if detection is solely based on the display of clinical signs. PrPd accumulation in the brain appeared to be related to the severity of clinical disease but not to the display of

    This study assessed driver reactions to 16 road hazard warning signs of various formats by projecting life-sized video of road scenes to drivers in a driving simulator. A range of measures, including attentional and search conspicuity, implicit and explicit recognition, dynamic and static comprehension, and sign priming were collected. Of the signs tested, road works and school warning signs were most often detected, remembered, and understood. Slippery surface warnings were associated with some of the lowest detection and comprehension rates. The effectiveness of the different formats depended on the type of hazard sign. In the case of road works warnings, a flashing variable message format was only slightly more conspicuous than the large dimension format, equal in comprehensibility, and perhaps somewhat worse in terms of memorability. For the school warnings, however, the flashing variable message format appeared to convey a greater sense of potential hazard, produced superior search conspicuity and priming, and was equal in terms of memorability and comprehensibility. The range of measures worked well as a whole with the two measures of conspicuity and the measure of static comprehension showing the greatest consistency.

  16. A Heuristic Clustering Algorithm for Mining Communities in Signed Networks

    Signed network is an important kind of complex network, which includes both positive relations and negative relations. Communities of a signed network are defined as the groups of vertices, within which positive relations are dense and between which negative relations are also dense. Being able to identify communities of signed networks is helpful for analysis of such networks. Hitherto many algorithms for detecting network communities have been developed. However, most of them are designed exclusively for the networks including only positive relations and are not suitable for signed networks.So the problem of mining communities of signed networks quickly and correctly has not been solved satisfactorily. In this paper, we propose a heuristic algorithm to address this issue. Compared with major existing methods, our approach has three distinct features. First, it is very fast with a roughly linear time with respect to network size. Second, it exhibits a good clustering capability and especially can work well with complex networks without well-defined community structures.Finally, it is insensitive to its built-in parameters and requires no prior knowledge.

    Mathematical syntax allows for the description of meaningful concepts in the physical sciences, and having nuanced proficiency in mathematical formalism is closely tied to communication and understanding of physical principles. The concept of equality is especially important, as it constrains and dictates the relationships between two equated expressions, and a student with detailed understanding of these relationships can derive physical meaning from syntactical expressions mediated by equals signs by knowing the ``meaning'' of equals signs. We delineate types of equals signs as used in undergraduate textbooks and develop a categorization scheme in order to investigate how equals signs are used paradigmatically and culturally in textbooks to convey physical meaning. We classify equals signs into general clusters (causal, definitional, assignment, balancing, and ``just math''), each cluster containing more detailed types. We investigate differences across various topics and between introductory and upper-division textbooks. We found that upper division textbooks are more likely to use balancing, definitional, and more complex kinds of assignment forms, while introductory texts have much higher frequencies of simple assignment and ``just math'' types.

  18. Polarity related influence maximization in signed social networks.

    Directory of Open Access Journals (Sweden)

    Dong Li

    Full Text Available Influence maximization in social networks has been widely studied motivated by applications like spread of ideas or innovations in a network and viral marketing of products. Current studies focus almost exclusively on unsigned social networks containing only positive relationships (e.g. friend or trust between users. Influence maximization in signed social networks containing both positive relationships and negative relationships (e.g. foe or distrust between users is still a challenging problem that has not been studied. Thus, in this paper, we propose the polarity-related influence maximization (PRIM problem which aims to find the seed node set with maximum positive influence or maximum negative influence in signed social networks. To address the PRIM problem, we first extend the standard Independent Cascade (IC model to the signed social networks and propose a Polarity-related Independent Cascade (named IC-P diffusion model. We prove that the influence function of the PRIM problem under the IC-P model is monotonic and submodular Thus, a greedy algorithm can be used to achieve an approximation ratio of 1-1/e for solving the PRIM problem in signed social networks. Experimental results on two signed social network datasets, Epinions and Slashdot, validate that our approximation algorithm for solving the PRIM problem outperforms state-of-the-art methods.

  19. Clinical signs and anatomical correlation of patellar tendinitis

    Rath Ehud

    2010-01-01

    Full Text Available Background: Patellar tendinitis is one of the several differential diagnosis of anterior knee pain. The clinical diagnosis of patellar tendinitis is based on tenderness to palpation at the inferior pole of the patella. The tenderness has been noted to be maximal when the knee is extended and the quadriceps relaxed, but a definite clinical sign for diagnosis is lacking. The accuracy of two clinical signs was assesed by a two-stage study which included physical examination, MRI and a cadaveric study. Materials and Methods: Two clinical signs, the "passive flexion-extension sign" and the "standing active quadriceps sign" were assessed in 10 consecutive patients with presumed patellar tendinitis. Five patients had an MRI, showed focal abnormality in the tendon. The location of the MRI finding corresponded, to the region of maximal tenderness. A cadaveric dissection was undertaken to describe the anatomy of the patella and the patellar tendon during these tests. Results: Both tests showed a significant decrease in tenderness at the area of inflammation when the patellar tendon was under tension. The cadaveric dissection showed that when the knee is flexed to 90΀ or when the quadriceps is tensioned the deep fibers of the tendon do not deform to anteriorly applied pressure. Conclusion: We suggest using these studies routinely in the evaluation of patients with anterior knee pain.

    Full Text Available This paper intends that the determining of how and to what extend the use of equal sign and relational thinking are supported in the mathematics course books for the primary education and students work books taught from 1st grade to 5th grade in for the primary education. In this study, the document analysis approach, which is one of the method, qualitative research was used for the data collection. This contexts/samples including equal sign in course book were examined and in this procedure, the operations-equal-answer and non-standard context used by McNeil et al (2006 were adapted. After completing of coding for equal sign, the samples supporting the relational thinking were determined and these samples were coded under the principal titles. As a result, it is determined that the equal sign is excessively used in the four series of the primary education 1.-5. grades mathematics course books and student work books as operations-equality-answer and, in these context, the samples emphasizing the relational meaning of equal sign required level.
