    A hybrid-optoelectronic correlator device and an algorithm are proposed for recognizing cuneiform inscription signs. The device is based on the extended correlator architecture with three liquid-crystal display(s) (LCD)s and three light detectors: one CCD camera for capturing the input image, one LCD for displaying the input image, two LCDs for the complex correlation filter (amplitude and phase parts), and two detectors for measuring the total and peak intensities of the output correlation information. The recognition algorithm is designed to allow automatic as well as real-time processing. The recognition results are given for the cuneiform signs impressed on an original clay tablet. The investigated tablet (VAT 12890 of the Pergamon Museum, Berlin, Germany) was found in Bogazk öy (Hattusha) and dates from the 14th century B.C. It is a fragment of the Epic of Gilgamesh in the Akkadian language with a large number of the sign samples.

    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.

    This monograph presents in great detail a large number of both unpublished and previously published Babylonian mathematical texts in the cuneiform script. It is a continuation of the work A Remarkable Collection of Babylonian Mathematical Texts (Springer 2007) written by Jöran Friberg, the leading expert on Babylonian mathematics. Focussing on the big picture, Friberg explores in this book several Late Babylonian arithmetical and metro-mathematical table texts from the sites of Babylon, Uruk and Sippar, collections of mathematical exercises from four Old Babylonian sites, as well as a new text from Early Dynastic/Early Sargonic Umma, which is the oldest known collection of mathematical exercises. A table of reciprocals from the end of the third millennium BC, differing radically from well-documented but younger tables of reciprocals from the Neo-Sumerian and Old-Babylonian periods, as well as a fragment of a Neo-Sumerian clay tablet showing a new type of a labyrinth are also discussed. The material is presen...

  5. Chemical inscriptions in Korean textbooks: Semiotics of macro- and microworld

    2006-03-01

    Thinking about macroscopic phenomena in terms of models based on the idea of microscopic particles (i.e., the particulate theory of matter) is one of the important goals for student learning in chemistry around the world. However, previous research suggests that students do not easily understand phenomena from a particle perspective, although such a perspective has many concrete aspects that ought to assist learners of chemistry. More than the textbooks of other countries, Korean chemistry texts tend to include colorful inscriptions. How, we might ask, do such inscriptions help learners of chemistry? The purpose of this study is to investigate the function and structure of chemical inscriptions in middle school science textbooks by drawing on a semiotic framework. We develop the concept of chemi (stry)-semiotics'' to unveil the work of reading required to understand chemical inscriptions in the way their authors intended them to be understood. The study began with the assumption that different kinds and functions (structure) of inscriptions constitute different signs that are available as sense-making resources in the learning process. We show that the difficulty in understanding the particulate nature of matter may result from the different processes of semiosis (interpretation and meaning making) between inscriptions depicting macroscopic and models based on microscopic particles.

  6. Network analysis of a corpus of undeciphered Indus civilization inscriptions indicates syntactic organization

    2010-01-01

    Archaeological excavations in the sites of the Indus Valley civilization (2500-1900 BCE) in Pakistan and northwestern India have unearthed a large number of artifacts with inscriptions made up of hundreds of distinct signs. To date there is no generally accepted decipherment of these sign sequences and there have been suggestions that the signs could be non-linguistic. Here we apply complex network analysis techniques to a database of available Indus inscriptions, with the aim of detecting patterns indicative of syntactic organization. Our results show the presence of patterns, e.g., recursive structures in the segmentation trees of the sequences, that suggest the existence of a grammar underlying these inscriptions.

    This paper introduces a novel methodology for the classification of ancient Greek inscriptions according to the writer who carved them. Inscription writer identification is crucial for dating the written content, which in turn is of fundamental importance in the sciences of history and archaeology. To achieve this, we first compute an ideal or "platonic" prototype for the letters of each inscription separately. Next, statistical criteria are introduced to reject the hypothesis that two inscriptions are carved by the same writer. In this way, we can determine the number of distinct writers who carved a given ensemble of inscriptions. Next, maximum likelihood considerations are employed to attribute all inscriptions in the collection to the respective writers. The method has been applied to 24 Ancient Athenian inscriptions and attributed these inscriptions to six different identified hands in full accordance with expert epigraphists' opinions.

    Cuneiform tablets tell the life and culture of Sumerian people in a sort of black and white tale because of the binary engraving technique. A leading question arises: did Mesopotamian people apply some kind of colour to decorate their tablets or to put emphasis on selected words? Some administrative and literary Sumerian cuneiform tablets of mid-third Millennium B.C. from the site of Kish (central Mesopotamia, modern Iraq) were dug up in twentieth-century and stored at the Ashmolean Museum of the Oxford University. Non-destructive micro-Raman spectroscopy is a powerful technique to detect the presence of residual pigments eventually applied to the engraving signs. Yellow, orange, red and white pigments have been detected and a possible identification has been proposed in this work. In particular yellow pigments are identified as Crocoite (PbCrO4), Lead stannate (Pb2SnO4); red pigments - hematite (Fe2O3) and cuprite (Cu2O); White pigments - Lead carbonate (PbCO3), calcium phosphate (Ca3(PO4)2), titanium dioxide (TiO2), gypsum (CaSO4.2H2O); orange pigment a composition of red and yellow compounds. These results suggest that Sumerian people invented a new editorial style, to overcome the binary logic of engraving process and catch the reader's eye by decorating cuneiform tablets. Finally, the coloured rendering of the tablet in their original view is proposed.

    Full Text Available Isolated tuberculosis of foot is a rare entity. Plenty of literature is available on osteoarticular tuberculosis but literature on tuberculosis of foot is limited. Additionally the condition mimics variety of other foot pathologies which can delay diagnosis and add to morbidity. We present a twelve year old boy who presented clinically with swelling, pain and discharging sinus of foot with a cystic lesion in medial cuneiform on radiography. Though histopathology and Ziehl Nielsen staining later on established the diagnosis, but initially it was mistaken as a case of mycotic osteomyelitis. Tuberculosis of foot, though rare, should always be one of the differential diagnoses in a patient presenting with bony lesion on radiography irrespective of absence of constitutional symptoms and negative tests for tuberculosis. If battery of tests fails to establish diagnosis, open biopsy with curettage and histopathology should be considered to work out the final diagnosis. [Int J Res Med Sci 2013; 1(4.000: 592-595

    2014-01-01

    We report the case of an 11-year-old boy who had sustained a soccer injury to his mid-foot. Plain radiography did not reveal any fracture to account for the severity of his symptoms or his inability to bear weight. Magnetic resonance imaging was undertaken and demonstrated the medial cuneiform to be a bipartite bone consisting of 2 ossicles connected by a synchondrosis. No acute fracture or diastasis of the bipartite bone was demonstrated; however, significant bone marrow edema was noted, corresponding to the site of the injury and his clinical point bony tenderness. This anatomic variant should be considered as a rare differential diagnosis in the skeletally immature foot. The injury was treated nonoperatively with a non-weightbearing cast and pneumatic walker immobilization, with successful resolution of his symptoms and a return to sports activity by 4 months after injury.

  16. The scribe of the founder's inscription of Saint Sava in Studenica

    2006-01-01

    Full Text Available The founder's inscription situated at the foot of the tambour in the Church of the Virgin in Studenica originating from 1208/9, is one of the oldest dated specimens of Serbian literacy. It was uncovered in 1951, during the conservation works in the monastery. Former research (conducted by Dj. Trifunović, has ascertained that inscriptions on the scrolls, books and frescoes in the monastery were written by the Greek artists who decorated the church. Scribal errors indicate beyond any doubt that Slavic was not the mother tongue of the scribes, and that they were not, or at least not sufficiently, familiar with the orthography of this language. In this paper the main focus has been directed at the founder's inscription, which has been put under detailed orthographic and palaeographic scrutiny. The morphology of some letters — the Greek "K", non-distinguishing between ižica (ippsilon and the Cyrillic "Č" — clearly indicates that in all probability the author of the inscription was a Greek, perhaps the very painter who signed his name in the Greek language on the Mandelion beneath the large founder's inscription.

  19. An assessment of the contributions of the pedunculopontine tegmental and cuneiform nuclei to anxiety and neophobia.

    Walker, S C; Winn, P

    2007-12-05

    The pedunculopontine tegmental and cuneiform nuclei are adjacent structures in the mesopontine tegmentum. The pedunculopontine has attracted interest because of its extensive reciprocal connections with corticostriatal systems and possible role in complex behavioral and cognitive processes; the cuneiform is thought to be part of a neural system important for organizing defensive behaviors. Excitotoxic lesions of the pedunculopontine have been shown to affect a variety of complex functions, including learning and attention, but it has been suggested that a consequence of lesions here is the production of an anxiety-like state. We present experiments to clarify the relative role of the pedunculopontine and cuneiform nuclei in anxiety-like states in rats, measured using the elevated plus maze, food neophobia and palatability tests, and by open field behavior. In addition, we measured (through Fos expression) the effect that being on the elevated plus maze had on the pedunculopontine and cuneiform nuclei. Bilateral ibotenate lesions of cuneiform increased anxiety-like responses on the elevated plus maze, food neophobia and open field tests. Bilateral ibotenate lesions of pedunculopontine that spared cuneiform did not produce anxiety-like behavior, but did disinhibit performance in all the tests. Lesions directed at the pedunculopontine produced anxiety-like effects only when there was also significant damage in the cuneiform. The data are discussed in terms of the relationships these nuclei have with different neural systems: pedunculopontine can be understood in terms of its hierarchical relationships with forebrain systems, while cuneiform is understood best in terms of its role in regulating responses to threatening stimuli.

    A 30-year-old non-German speaking patient suffered an ankle sprain while playing beach volleyball. Conventional radiography did not reveal any fractures. The patient was treated with a Geisha cast for immobilization and relief and was also informed about pain-dependent weight bearing using an illustrated information sheet. In the course of the healing process the patient consulted the orthopedic department a second time. During a third visit he left before consultation as he felt that the waiting time was too long. Because he disagreed with the treatment he visited an orthopedist who ordered a magnetic resonance imaging (MRI) scan of the patient’s foot. The MRI scan revealed an undislocated fracture of the cuneiform I bone. A control scan was conducted 2 months later and complex regional pain syndrome (CRPS) was diagnosed. The orthopedist ordered treatment based on a therapy with a VacoPed® orthesis. When there was no improvement in the healing process the patient sued the orthopedic surgeon for medical malpractice due to incorrect load and subsequent pain for € 40,000. All courts up to the Federal Court of Germany dismissed the case as no expert witnesses could find any errors in treatment. The court held that the medical information of the non-German speaking patient was sufficient against the defendant’s arguments. It is, however, noteworthy that the burden of proof for sufficient medical information of a patient is always placed on the treating physician.

  1. The Sea Peoples, from cuneiform tablets to carbon dating.

    Directory of Open Access Journals (Sweden)

    David Kaniewski

    Full Text Available The 13(th century BC witnessed the zenith of the Aegean and Eastern Mediterranean civilizations which declined at the end of the Bronze Age, ∼3200 years ago. Weakening of this ancient flourishing Mediterranean world shifted the political and economic centres of gravity away from the Levant towards Classical Greece and Rome, and led, in the long term, to the emergence of the modern western civilizations. Textual evidence from cuneiform tablets and Egyptian reliefs from the New Kingdom relate that seafaring tribes, the Sea Peoples, were the final catalyst that put the fall of cities and states in motion. However, the lack of a stratified radiocarbon-based archaeology for the Sea People event has led to a floating historical chronology derived from a variety of sources spanning dispersed areas. Here, we report a stratified radiocarbon-based archaeology with anchor points in ancient epigraphic-literary sources, Hittite-Levantine-Egyptian kings and astronomical observations to precisely date the Sea People event. By confronting historical and science-based archaeology, we establish an absolute age range of 1192-1190 BC for terminal destructions and cultural collapse in the northern Levant. This radiocarbon-based archaeology has far-reaching implications for the wider Mediterranean, where an elaborate network of international relations and commercial activities are intertwined with the history of civilizations.

Analisamos esses problemas a partir de três pontos de vista. Inicialmente, consideramos as mediações intelectuais pelas quais passa um texto cuneiforme até sua tradução. Em segundo lugar, tratamos das particularidades da conceituação matemática cuneiforme, isto é, das diferenças em relação à matemática de nosso tempo. Por fim, abordamos aspectos das línguas originais dos textos cuneiformes que ainda estão em discussão pelo campo. Como conclusão, sugerimos que os resultados dessa análise são relevantes não somente para o processo de tradução, mas também para a leitura de traduções de textos matemáticos cuneiformes.

Remarks about The Translation of Mathematical Cuneiform Texts Abstract In this work, I deal with certain problems of translation that belong to cuneiform texts in general and more specifically to mathematical cuneiform texts. I analyse these problems from three points of view. Initially, I consider the intellectual mediations a cuneiform text undergoes until its translation. Next, I deal with the particularities of the concepts of the cuneiform mathematics, that is to say, its differences in relation to the mathematics of our time. Lastly, I treat aspects of the original languages of cuneiform texts that are still under discussion by the field. As a conclusion, I suggest that the results of this analysis are relevant not only to the translation process, but also to the reading of translations of mathematical cuneiform texts.

    We reconstruct the published year of each cuneiform tablet of the Nuzi society in ancient Mesopotamia. The tablets are on land transaction, marriage, loan, slavery contracts, etc. The number of tablets seems to increase by logistic growth. It may show the dynamics of concentration of lands or other properties into few powerful families in a period of about sixty years and most of them are in about thirty years. We reconstruct family trees and social networks of Nuzi and estimate the published years of cuneiform tablets consistently with the trees and networks, formulating least squares problems with linear inequality constraints.

    Inscriptions carved in a rock on the Greek island of Thera and dating from the 6th or 7th century BC have homosexual contents. Originally considered a testimony to ritual sacred acts, they were described by Marrou (1956) and Dover (1978) as vulgar pornographic graffiti. Arguments against this view and in favor of the formal ritual interpretation are proposed. A final explanation is suggested, conforming to local customs and the general conceptions of ancient Greek boy-love.

  5. Radiographic Relevance of the Distal Medial Cuneiform Angle in Hallux Valgus Assessment.

    Science.gov (United States)

    Hatch, Daniel J; Smith, Abigail; Fowler, Troy

    2016-01-01

    The angle formed by the distal articular facet of the medial cuneiform has been evaluated and discussed by various investigators. However, no consistent method has been available to radiograph and measure this entity. The wide variability of the angle is not conducive to comparative analysis. Additionally, investigators have noted that the angles observed (obliquity) vary greatly because of changes in radiographic angle, foot position, rotation of the first ray, and declination of the first metatarsal. Recognizing that these variables exist, we propose a reproducible assessment using digital radiography and application of deformity of correction principles. Our results have indicated a mean distal medial cuneiform angle of 20.69° in normal feet, 23.51° with moderate hallux valgus, and 20.41° with severe hallux valgus deformity. The radiograph beam was kept at 15° from the coronal plane. An inverse relationship was found between the distal medial cuneiform angle and bunion severity. This was in contrast to our expected hypothesis. The overall angle of the first metatarsal-medial cuneiform did, however, correlate with the severity of the bunion deformity (p positioning, and soft tissue imbalances. Perhaps, 3-dimensional computed tomography imaging will provide better insight into this entity.

    Directory of Open Access Journals (Sweden)

    Valentina Consoli

    2013-07-01

    Full Text Available A wide literary tradition narrated by D.S., 4.22.5, tied to musical legends concerning the cicadas on the Alex river, refers to the passage of Heracles across the boundary territory between Rhegion and Locri. The careful reading of the texts, however, induces us to set the known episode about Heracles, disturbed by cicadas while resting, on the northern boundary between the two chorai along the Tyrrhenian side, within the area marked by a strong conflict between the two rival apoikiai. The bronze leaf with the inscription to Heracles Rheginus just comes from this border area of Rhegion chora, inside the district of Metauros river, signed by both indigenous settlements and Locresian claims. The inscription should not be taken as a certain clue for the existence of a sanctuary of the hero, but can represent a clear sign of his strong presence as a cultic reference for the Rheginian scattered through the colonial eschatia. Both analyzing the inscription historical-cultural context of provenance and considering the liminal worshiping places of the heros-theos, linked to the youth rites of passage, we could explain the rise of the dedication referring to the activity of the ephebes garrisoning the colonial chora.

    2016-07-01

    Isolated cuneiform fractures are rare and are often missed on plain radiographs, leading to delayed diagnosis and delayed return to sport. The authors of this study present a 32-year-old male ice hockey player who sustained trauma to his dorsal midfoot from a slap shot. Radiographs were negative for fracture. After inability to wean out of the controlled ankle movement boot, magnetic resonance imaging was ordered, demonstrating a middle cuneiform fracture. The patient was seen in physical therapy, where aquatic therapy, strength training, and cardiovascular conditioning were progressed. He was able to wean out of the controlled ankle movement boot at 7 weeks after injury and return to playing ice hockey. Here, we outline rehabilitation and a diagnostic and rehabilitative algorithm for those who sustain trauma to the dorsal midfoot with suspected fracture.

  10. Preprocessing Algorithm for Deciphering Historical Inscriptions Using String Metric

    2016-07-01

    Full Text Available The article presents the improvements in the preprocessing part of the deciphering method (shortly preprocessing algorithm for historical inscriptions of unknown origin. Glyphs used in historical inscriptions changed through time; therefore, various versions of the same script may contain different glyphs for each grapheme. The purpose of the preprocessing algorithm is reducing the running time of the deciphering process by filtering out the less probable interpretations of the examined inscription. However, the first version of the preprocessing algorithm leads incorrect outcome or no result in the output in certain cases. Therefore, its improved version was developed to find the most similar words in the dictionary by relaying the search conditions more accurately, but still computationally effectively. Moreover, a sophisticated similarity metric used to determine the possible meaning of the unknown inscription is introduced. The results of the evaluations are also detailed.

    In the inscriptions of Western Zhou bronzes there are quantities of calendrical data recording years, months and days. Of them are those completely indicating the year of king's reign, the moon, the lunar phase, and the day designated by the Heavenly Stems and Earthly Branches system. These records are of great significance to studying the Western Zhou calendar, establishing the bronze inscription calendar, and identifying the reigning years of the Western Zhou kings.

    Full Text Available The meaning of Proverbs 30:18-19 has long been disputed. Most scholars interpret the Biblical couplets textually on stylistic features only; an explanation of the contextual association between the four motifs mentioned (eagle, serpent, boat, man and woman has not yet been undertaken. The present paper aims at shedding light on the motivation for this association, taking into consideration ancient Near Eastern cuneiform compositions for the first time. It is further suggested that Proverbs 30:18-19 derived originally from a riddle that had its setting in a wedding ceremony.El significado de Proverbios 30:18-19 sigue desafiando la exégesis de los biblistas. La mayoría de los comentaristas interpretan los versos bíblicos textualmente, ciñéndose al análisis de las figuras de estilo.

    Cuneiform is an ancient form of writing in which wooden reeds were used to impress shapes upon moist clay tablets. Upon drying, the tablets preserved the written script with remarkable accuracy and durability. There are currently hundreds of thousands of cuneiform tablets spread throughout the world in both museums and private collections. The global scale of these artifacts presents several problems for scholars who wish to study them. It may be difficult or impossible to obtain access to a given collection. In addition, photographic records of the tablets many times prove to be inadequate for proper examination. Photographs lack the ability to alter the lighting conditions and view direction. As a solution to these problems, we describe a 3D scanner capable of acquiring the shape, color, and reflectance of a tablet as a complete 3D object. This data set could then be stored in an online library and manipulated by suitable rendering software that would allow a user to specify any view direction and lighting condition. The scanner utilizes a camera and telecentric lens to acquire images of the tablet under varying controlled illumination conditions. Image data are processed using photometric stereo and structured light techniques to determine the tablet shape; color information is reconstructed from primary color monochrome image data. The scanned surface is sampled at 26.8 μm lateral spacing and the height information is calculated on a much smaller scale. Scans of adjacent tablet sides are registered together to form a 3D surface model.

  15. On Two Old Russian Inscriptions from Belarus and Poland

    Directory of Open Access Journals (Sweden)

    Savva M. Mikheev

    2015-08-01

    Full Text Available Two Old Russian graffiti inscriptions are examined in the present paper. The first one, dating back to the late 13th–early 14th centuries, is located on one of the walls of the Savior Transfiguration Church in the St. Euphrosyne convent in Polotsk, Belarus. It reads Marъkova žana dobra ‘Mark’s wife is good.’ The second graffito was inscribed on a knife handle excavated in Drohiczyn, Eastern Poland (Old Russian Dorogyčinъ, and dates to the end of the 11th through the 12th centuries. The inscription reads Ežьkovъ nožь a iže i ukradetь proklętъ  . . . ‘Ezhko’s knife. Whoever steals it, be cursed . . .’ Although both inscriptions have been published, the present study adds more in-depth paleographic and linguistic commentary and suggests corrected readings. The laudatory inscription from Polotsk is particularly interesting because it contains an early example of a spelling reflecting yakanye, a trait of Belarusian phonetics, whereas the interest of the Drohiczyn inscription lies in its unusual paleographic features.

  1. Children's Use of Inscriptions in Argumentation about Socioscientific Issues

    Science.gov (United States)

    Xiao, Sihan

    Engaging science in everyday life often means not advancing knowledge or making new claims, but evaluating given claims with available evidence. In everyday situations, evidence is usually presented in some type of inscription (e.g. tables, diagrams, and other images). This study explores elementary students' use of inscriptions as evidence in written arguments about socioscientific issues and how a school year of science instruction may play a role in that use. Three science teachers and their 102 students in 5th and 6th grades at a progressive urban K-6 school participated in this study. I administered a written argument task at the beginning and the end of the 2013--2014 school year, in which students were asked to justify their personal decisions about either alternative energy use or genetically modified organisms. Throughout the year, I worked closely with the teachers to organize classroom instruction towards promoting argumentation and coordination between claims and evidence, and videotaped their science lessons. Content analysis on students' written arguments reveals that photos were cited the most in students' written arguments, while tables were cited the least. Students tended to merely point to an inscription without articulate its relation to a particular claim, or to assert that an inscription "shows" a claim without saying how. They were also likely to credit inscriptions that aligned with their own position rather than discount those that supported counterclaims. From pre to post, these patterns did not change significantly. Analysis on science instruction further shows that the contestability of the claims students encountered in the classroom was low, meaning that they were not framed in arguable ways. The resources available to students for resolving these claims were also limited. The classroom discourse was not open enough for productive argumentation. These patterns may potentially account for the lack of change in students' use of

  3. Choreographic Inscriptions: A Framework for Exploring Sociomaterial Influences on Qualities of Movement for HCI

    Directory of Open Access Journals (Sweden)

    Lian Loke

    2016-01-01

    Full Text Available With the rise of ubiquitous computing technologies in everyday life, the daily actions of people are becoming ever more choreographed by the interactions available through technology. By combining the notion of inscriptions from actor–network theory and the qualitative descriptors of movement from Laban movement analysis, an analytic framework is proposed for exploring how the interplay of material and social inscriptions gives rise to movement patterns and behaviors, translated into choreographic inscriptions described with Laban effort and shape. It is demonstrated through a case study of an affective gesture mobile device. The framework provides an understanding of (a how movement qualities are shaped by social and material inscriptions, (b how the relative strength of inscriptions on movements may change according to different settings and user appropriation over time, and (c how transforming inscriptions by design across different mediums can generate action spaces with varying degrees of openness.

    The cuneiform nucleus (CnF) is a sympathoexcitatory area involved in the central cardiovascular regulation. Its role in the maintaining vasomotor tone has, however, not yet been clarified. In the present study the effects of cobalt chloride (CoCl(2)) a nonselective synapse blocker and NMDA and non-NMDA glutamate receptors on resting mean arterial blood pressure and heart rate of CnF have been evaluated. CoCl(2), AP5 (an NMDA receptor antagonist) and CNQX (an AMPA/kinase receptor antagonist) (100nl) were microinjected into the CnF of anesthetized rats. The blood pressure and heart rate were recorded throughout the experiment. The responses of blood pressure and heart rate were compared with the pre-injection (paired t-test) and control (independent t-test) values. Microinjection of CoCl(2), AP5 and CNQX did not change the basal blood pressure and heart rate. In conclusion, our present study indicates that the CnF is not important in the regulation of cardiovascular tone. Copyright © 2011. Published by Elsevier Ireland Ltd.

    Lee, David; Cunningham, Colin R

    2012-01-01

    Ultrafast laser inscription (ULI) is a rapidly maturing technique which uses focused ultrashort laser pulses to locally modify the refractive index of dielectric materials in three-dimensions (3D). Recently, ULI has been applied to the fabrication of astrophotonic devices such as integrated beam combiners, 3D integrated waveguide fan-outs and multimode-to-single mode convertors (photonic lanterns). Here, we outline our work on applying ULI to the fabrication of volume phase gratings (VPGs) in fused silica and gallium lanthanum sulphide (GLS) glasses. The VPGs we fabricated had a spatial frequency of 333 lines/mm. The optimum fused silica grating was found to exhibit a first order diffraction efficiency of 40 % at 633 nm, but exhibited approximately 40 % integrated scattered light. The optimum GLS grating was found to exhibit a first order diffraction efficiency of 71 % at 633 nm and less than 5 % integrated scattered light. Importantly for future astronomy applications, both gratings survived cooling to 20 K....

    We used ultrafast laser inscription to fabricate three-dimensional integrated optical transitions that efficiently couple light from a multimode waveguide to a two-dimensional array of single mode waveguides and back. Although the entire device has an average insertion loss of 5.7 dB at 1539 nm, only ≈0.7 dB is due to mode coupling losses. Based on an analysis which is presented in the paper, we expect that our device should convert a multimode input into an array of single modes with a loss of ≈2.0 dB, assuming the input coupling losses are zero. Such devices have applications in astrophotonics and remote sensing.

  10. An unpublished Roman inscription from Cortinal de San Juan (Salvatierra de Tormes, Salamanca

    Verónica PÉREZ DE DIOS

    2015-11-01

    Full Text Available In this paper is presented a slate with a Roman inscription found in archaeological survey work conducted in September 2014 in Cortinal de San Juan (Salvatierra de Tormes. This site has been, since its discovery and cataloging, a place of reference for the late Roman and Visigothic settlement Southeast Salamanca. Currently, this archaeological site is partially flooded by the Santa Teresa swamp. The main feature of this Roman inscription is that the slate support isn’t usual in the chronology proposed for such inscription. Despite the fact that other archaeological materials of Cortinal de San Juan are associated with late Roman or Visigothic chronocultural context, the type of capital letter, the large size of the letter, and the parallels established with other finds of similar chronology suggest this inscription could be part of a Roman anthroponym as the most successful interpretive hypothesis.

  11. Middle school students' development of inscriptional practices in inquiry-based science classrooms

    Science.gov (United States)

    Wu, Hsin-Kai

    The purpose of this study is to characterize the learning practices demonstrated by seventh graders when they used various scientific inscriptions in an inquiry-based learning environment. Inscriptions are types of transformations, such as graphs, diagrams, data tables, symbols, maps, and models, that materialize or visualize an entity into another format or mode. As suggested by science studies, scientific knowledge and the reality of science are constructed through manipulating a variety of inscriptions. However, little is known about how middle school students make use of inscriptions over time and what resources or features of the learning environment support students in doing so. Drawing on a naturalistic approach, this classroom-based study aims to characterize students' inscriptional practices, trace their learning trajectories, examine potential use of various scientific inscriptions, and analyze the learning supports and resources provided by the teachers and the learning environment. This eight-month study is conducted in two inquiry-based science classes with participation of two teachers and 27 seventh graders. Two student dyads from each class were observed intensively. Multiple sources of data were collected, including fieldnotes, classroom video recordings, process video recordings, computer-based models, webpages, science reports, notebooks, and transcripts from interviews with students and teachers. Several analytical steps were taken to analyze and synthesize these data. Expanding upon early research on students' learning of inscriptions, this study shows that seventh graders could demonstrate competent, purposeful inscriptional practices when they were scaffolded by the teachers and the curriculum in a learning environment where the inscriptional activities were sequenced, iterated, and embedded in scientific inquiry. Additionally, using inscriptions in science classrooms provided students with opportunities to engage in thoughtful discussions

  14. Inscribing Authority: Female Title Bearers in Jewish Inscriptions

    Directory of Open Access Journals (Sweden)

    Carrie Duncan

    2012-02-01

    Full Text Available This paper investigates representations of gender in the material culture of the ancient synagogue. The pertinent data are numerous dedicatory and funerary inscriptions linking individual Jews, men and women, with titles seemingly associated with leadership in Late Antique synagogues (ca. 200–600 CE. Bernadette Brooten’s influential 1982 monograph argued against the prevailing tendency to characterize these titles as indications of power, authority, and responsibility when associated with men but as meaningless flattery when applied to women. She suggests that synagogue titles denote power, authority and responsibility on all title bearers equally, both men and women. I question the continued utility of proffering female title-holders as enumerable examples of powerful women rescued from their forgotten place in history. Using theoretical insights developed by historians Elizabeth Clark and Gabrielle Spiegel, this paper will engage a comparative analysis with the work of Riet van Bremen and Saba Mahmood to develop new methods of conceptualizing women’s authority in early Jewish communities. I propose that viewing women’s synagogue titles as culturally constructed representations allows for a fruitful inquiry into how women’s titles were used by male-dominated synagogue communities in their self-articulation and public presentation of Judaism.

    2013-01-01

    Full Text Available The epigraphic material from the region of Naissus, in spite of its relative scarcity and poor state of preservation, offers valuable examples of Vulgar Latin usage. Interesting phenomena include an instance of the imperial name Pertinax in the form Pertenax, which may be due to a vulgar reinterpretation of the name (‘Very Tough’, cf. Constans, Valens, sim. and may imply rhizotony (Perténax; the adjective superstantes ‘survivors’, apparently the issue of two consequent vulgar developments, superstes > superstens (hypercorrect spelling > superstans (false analogy; an isosyllabic 3rd declension nominative singular, Melioris (from the name Melior, as well as a 3rd decl. dative singular generi from the 2nd decl. noun gener ‘son-in-law’; an early borrowing from Germanic, brutes ‘daughter-in-law’; a ‘weak’ future participle, sequiture, for secuturae; the bastard noun volumptas, cf. voluntas and voluptas; a correlative construction with sic...sic for quemadmodum...sic; and the verb adjuvare followed by a dative, which illustrates a vulgarism known from the Glossaries. Another kind of vulgarity, which is rather a matter of simplicity than purely linguistic incompetence, is found in cases such as an epitaph whose dedicator calls herself bene merita; or a semi-metric inscription-a commaticum-whose actual text may be the outcome of tampering with a regular epigraphic poem

  20. Primary Intraosseous Malignant Peripheral Nerve Sheath Tumor of the Medial Cuneiform: A Case Report and Review of the Literature.

    Muthusamy, Saravanaraja; Conway, Sheila A; Pitcher, J David; Temple, H Thomas

    Peripheral nerve sheath tumors (benign and malignant) usually arise in the soft tissues and are unusual in bone. Intraosseous peripheral nerve sheath tumors are usually benign and constitute approximately 0.2% of all bone tumors. Intraosseous malignant peripheral nerve sheath tumors (MPNSTs) are uncommon and usually result from secondary invasion. Only a few cases of primary intraosseous MPNSTs have been reported in published studies, and these were localized mostly in the mandible (approximately 50%) or maxilla, spine, and, occasionally, in the appendicular skeleton. To the best of our knowledge, we report the first case of primary intraosseous MPNST involving a midtarsal bone (medial cuneiform). The patient was a 62-year-old female who presented with pain and tenderness but without swelling. Imaging revealed nonspecific findings, and the preoperative computed tomography-guided biopsy findings were consistent with MPNST. The patient was treated with neoadjuvant radiotherapy, followed by wide local excision and allograft reconstruction. At the final follow-up examination (24 months), the graft had been incorporated without evidence of local recurrence or distant disease. The patient with primary intraosseous MPNST of the medial cuneiform described in the present report presented with nonspecific clinical and radiologic findings. Thus, a high index of suspicion and histopathologic examination, including immunohistochemistry, are necessary for an accurate diagnosis.

These images and figures that had been written/drawn in first centuries of the Christ in our opinion, are the most important ones among existent ones in whole geography beginning from Siberia reaching to France, Portugal. In surroundings of those inscriptions which we think they had been written/drawn by Turks believed in Tengriism (Shamanism, there are also tumulus/tumuli that are old Turkish settlement and old Turkish graveyards. Another significance of petroglyphs and inscriptions in Esatlı is to be able to see the evolution of this chain: petroglyph, ideogram, pictogram, marker, syllable, semi-syllable and letter. It is possible to perceive many stages of the evolution from petroglyph to letter here.

    2002-09-01

    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.

    2015-02-01

    In this paper two non-invasive non-destructive alternative techniques to the traditional and invasive technique of squeezes are presented alongside with specialized developed processing methods, aiming to help the epigraphists to reveal and analyse weathered letters in ancient Greek inscriptions carved in masonry or marble. The resulting 3D model would serve as a detailed basis for the epigraphists to try to decipher the inscription. The data were collected by using a Structured Light scanner. The creation of the final accurate three dimensional model is a complicated procedure requiring large computation cost and human effort. It includes the collection of geometric data in limited space and time, the creation of the surface, the noise filtering and the merging of individual surfaces. The use of structured light scanners is time consuming and requires costly hardware and software. Therefore an alternative methodology for collecting 3D data of the inscriptions was also implemented for reasons of comparison. Hence, image sequences from varying distances were collected using a calibrated DSLR camera aiming to reconstruct the 3D scene through SfM techniques in order to evaluate the efficiency and the level of precision and detail of the obtained reconstructed inscriptions. Problems in the acquisition processes as well as difficulties in the alignment step and mesh optimization are also encountered. A meta-processing framework is proposed and analysed. Finally, the results of processing and analysis and the different 3D models are critically inspected and then evaluated by a specialist in terms of accuracy, quality and detail of the model and the capability of revealing damaged and "hidden" letters.

Problems in the acquisition processes as well as difficulties in the alignment step and mesh optimization are also encountered. A meta-processing framework is proposed and analysed. Finally, the results of processing and analysis and the different 3D models are critically inspected and then evaluated by a specialist in terms of accuracy, quality and detail of the model and the capability of revealing damaged and ”hidden” letters.

    Optical microfibers functionalized with surface microstructures, have attracted great attentions and been widely used in various optical devices. In this work, we demonstrated a technique to fabricate microstructures on polymer coated optical microfibers via ultraviolet inscription. Optical microfibers were firstly functionalized with ultraviolet photosensitivity by surface PMMA jackets. Microstructures were fabricated on optical microfibers via point-by-point ultraviolet inscription since the photo-etching in PMMA jackets. As an illustration, a 2-mm-long microfiber long period grating (MLPG) with a pitch of 80 μm was inscribed. The diameter of optical microfiber is 5.4 μm and a resonant dip of 15dB was observed at 1377 nm. The MLPG showed a high sensitivity of strain and axial force, i.e., -1.93 pm/μɛ and -867 μN/nm. Sealed by a PMMA housing, the temperature sensitivity of MLPG could be enhanced from -12.75 pm/°C to -385.11 pm/°C. This technique demonstrates ultraviolet inscription of MLPGs and also provides an approach to fabricate microstructures on optical microfiber via ultraviolet exposure.

    The combination of fiber Bragg grating inscription with femtosecond laser sources and the usage of the Talbot interferometer setup not only gives access to the fabrication of Bragg gratings in new types of materials but also allows, at the same time, to keep the high flexibility of an interferometric setup in choosing the Bragg grating wavelength. Since the spatial and temporal coherence properties of the femtosecond laser source differ strongly from those of conventional laser sources, specific limits and tolerances in the interferometric setup have to be considered. Such limits are investigated on the basis of an analytical ray tracing model. The results are applied to tolerance measurements of fiber Bragg grating reflections recorded with a DUV sub-picosecond laser source at 262 nm. Additionally we demonstrate the wavelength versatility of the two-beam interferometer setup for femtosecond inscription over a 40 nm wavelength band. Inscription experiments in Al/Yb doped silica glasses are demonstrated as a prove for the access to non-photosensitive fibers.

    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.

    Full Text Available Fracture dislocation of the navicular bone, fracture of the cuboid, cuneiform, and longitudinal split fracture of the lateral malleolus is a rare combination of fractures. This is a high velocity injury fracture and can be caused by forcible plantar flexion and inversion of the foot at the time of impact onto the ground. Here we reported such a case in a 35-year-old male patient who was treated by open reduction and fixation with a partially threaded screw and two K-wires for the navicular bone, and two interfragmentary screws with a one third tubular plate for the lateral malleolus. K-wires were removed 6 weeks after surgery followed by partial weight bearing. After 6 months, the patient can walk normally with minimal pain and swelling of the foot.

    In this work, fibre Bragg gratings (FBGs) were inscribed in two different undoped poly- (methyl methacrylate) (PMMA) polymer optical fibres (POFs) using different types of UV lasers and their inscription times, temperature and strain sensitivities are investigated. The POF Bragg gratings (POFBGs......) were inscribed using two UV lasers: a continuous UV HeCd @325 nm laser and a pulsed UV KrF @248 nm laser. Two PMMA POFs are used in which the primary and secondary preforms (during the two-step drawing process) have a different thermal treatment. The PMMA POFs drawn in which the primary or secondary...... preform is not specifically pre-treated need longer inscription time than the fibres drawn where both preforms have been pre-annealed at 80 °C for 2 weeks. Using both UV lasers, for the latter fibre much less inscription time is needed compared to another homemade POF. The properties of a POF fabricated...

    Inscriptions on the Han period pictorial stones, as this sort of relief itself, are broadly distributed across the country. With extensively involving contents, they present one aspect of the change of the mourning concept in the Han period and reflect the intensify of care for living people. They tell of the existence of folk versions on historical figures' careers beyond history books written in biographical style. Meanwhile, they provide a standard for the chronological study of Han pictorial stones.The official positions mentioned in these inscriptions can be used in comparative study of archaeological and literal evidence to supply omission in historical documents and especially to correct errors in textual records. It is known from pictorial stone inscriptions that there already existed the official position of Mt.Tai governor in the Eastern Han period.

  17. The Effect of Scaffolding Strategies for Inscriptions and Argumentation in a Science Cyberlearning Environment

    2016-08-01

    Scientific inscriptions—graphs, diagrams, and data—and argumentation are integral to learning and communicating science and are common elements in cyberlearning environments—those involving the use of networked learning technologies. However, previous research has indicated that learners struggle to use inscriptions and when they engage in argumentation, the learning of science content becomes secondary to the learning of argumentation skills. The purpose of this study was to evaluate two scaffolding strategies for these elements in a secondary school context: (1) self-explanation prompts paired with a scientific inscription and (2) faded worked examples for the evaluation and development of scientific arguments. Participants consisted of ninth and tenth grade students (age 13-16 years; N = 245) enrolled in state-mandated biology courses taught by four different teachers. A three-factor mixed model analysis of variance with two between factors (self-explanation prompts and faded worked examples) and one within factor (pre-, post-, delayed posttest) was used to evaluate the effects on the acquisition and retention of domain-specific content knowledge. Results indicated that neither strategy influenced the acquisition and retention of science content in a positive (i.e., learning) or negative (i.e., expertise reversal effect) way. Thus, general prompts were as effective as either of the scaffolding conditions. These unanticipated results suggest that additional research is warranted for learning scaffolds with pre-college populations where the gains were established with college-aged participants.

    Polymers containing azo-benzene groups are useful holographic recording materials. In these materials the efficient mixed amplitude and phase gratings, frequently accompanied with photoinduced-surface relief gratings, can be inscribed with polarized laser light. The light-induced trans-cis-trans photoisomerization of azo-benzene groups is responsible for optical anisotropy in such systems. The aim of the present work is to study the dynamics of grating inscription in Disperse Red 1 doped deoxyrbonucleic acid- hexadecyltrimethylammonium material (DR1-DNACTMA) using 16 ps laser pulses (532 nm, 1.3 mJ). Results are compared with that obtained for other polymeric matrices loaded with DR1. The dynamics of the grating growth, due to repeated pulses from picosecond laser with 10 Hz repetition rate, was probed by measuring the intensity of the first order of diffraction of a cw He-Ne. We report results in function of the light polarization of writing beams. In this paper we present the first results of the grating inscription in functionalized DNA (in the picosecond pulse regime).

    2014-12-01

    An orientation-sensitive fiber-optic accelerometer based on grating inscription over fiber cladding has been demonstrated. The sensor probe comprises a compact structure in which a short section of thin-core fiber (TCF) stub containing a "cladding" fiber Bragg grating (FBG) is spliced to another single-mode fiber (SMF) without any lateral offset. A femtosecond laser side-illumination technique was utilized to ensure that the grating inscription remains close to the core-cladding interface of the TCF. The core mode and the cladding mode of the TCF are coupled at the core-mismatch junction, and two well-defined resonances in reflection appear from the downstream FBG, in which the cladding resonance exhibits a strong polarization and bending dependence due to the asymmetrical distribution of the cladding FBG along the fiber cross section. Strong orientation dependence of the vibration (acceleration) measurement has been achieved by power detection of the cladding resonance. Meanwhile, the unwanted power fluctuations and temperature perturbations can be referenced out by monitoring the fundamental core resonance.

    A new method for phase-shifted fiber Bragg grating (PS-FBG) inscription in single mode fiber by fusion splicing technique and femtosecond laser is presented. The PS-FBG is produced by exposing the fusion spliced fiber with femtosecond laser through a uniform phase mask. The transmission spectrum of the PS-FBG shows a nonlinear red shift during the inscription process, and two or three main dips can be observed due to the formation of one or two FBG-based Fabry-Pérot structures by controlling the exposure intensity and time of the laser. For a peak power density of 4.8×1013 W/cm2, the induced refractive index modulation can reach to 6.3×10-4 in the fiber without sensitization. The PS-FBG's temperature, strain and pressure characteristics are also experimentally studied. These PS-FBGs can be potentially used for multiple wavelength fiber lasers, filters and optical fiber sensors.

  5. Archaeology Through Computational Linguistics: Inscription Statistics Predict Excavation Sites of Indus Valley Artifacts.

    2016-11-01

    Computational techniques comparing co-occurrences of city names in texts allow the relative longitudes and latitudes of cities to be estimated algorithmically. However, these techniques have not been applied to estimate the provenance of artifacts with unknown origins. Here, we estimate the geographic origin of artifacts from the Indus Valley Civilization, applying methods commonly used in cognitive science to the Indus script. We show that these methods can accurately predict the relative locations of archeological sites on the basis of artifacts of known provenance, and we further apply these techniques to determine the most probable excavation sites of four sealings of unknown provenance. These findings suggest that inscription statistics reflect historical interactions among locations in the Indus Valley region, and they illustrate how computational methods can help localize inscribed archeological artifacts of unknown origin. The success of this method offers opportunities for the cognitive sciences in general and for computational anthropology specifically.

    We report the ultrafast laser fabrication and mid-IR characterization (3.39 microns) of four-port evanescent field directional couplers. The couplers were fabricated in a commercial gallium lanthanum sulphide glass substrate using sub-picosecond laser pulses of 1030 nm light. Straight waveguides inscribed using optimal fabrication parameters were found to exhibit propagation losses of 0.8 dB/cm. A series of couplers were inscribed with different interaction lengths, and we demonstrate power splitting ratios of between 8% and 99% for mid-IR light with a wavelength of 3.39 microns. These results clearly demonstrate that ultrafast laser inscription can be used to fabricate high quality evanescent field couplers for future applications in astronomical interferometry.

    Using ultrafast laser inscription, we report the fabrication of a prototype three-dimensional 121-waveguide fan-out device capable of reformatting the output of a 120 core multicore fiber (MCF) into a one-dimensional linear array. When used in conjunction with an actual MCF, we demonstrate that the reformatting function using this prototype would result in an overall throughput loss of approximately 7.0 dB. However, if perfect coupling from the MCF into the fan-out could be achieved, the reformatting function would result in an overall loss of only approximately 1.7 dB. With adequate development, similar devices could efficiently reformat the output of so-called "photonic lanterns" fabricated using highly multicore fibers.

    In order to make the whole fiber core modified, an improved point-by-point inscription method (called a transversal-scanning inscription method) is proposed to fabricate long period fiber gratings (LPFGs) by using femtosecond laser. LPFGs with an attenuation depth of 16 dB are achieved within the wavelength range of 1580-1680 nm. We have compared the bending properties of LPFGs fabricated by the line-by-line scanning inscription method and the transversal-scanning inscription method at the orthogonal directions. It is found that increasing scanning area using the transversal-scanning method can enhance the bend sensitivity obviously. The resulting curvature sensitivities are -4.82 nm/m-1 and -1.63 nm/m-1 at the 0° and 90° bend orientations respectively, within the curvature range from 1.75 m-1 to 3 m-1 in the experiment. The LPFG-I fabricated by the line-by-line scanning inscription method experiences red-shift, while the LPFG-II fabricated by the transversal-scanning inscription method experiences blue-shift.

    The cuneiform (CnF) and Kolliker-Fuse (KF) nuclei are implicated in several functions including regulation of cardiovascular system and pain modulation. The KF also is a potential candidate for relaying the CnF cardiovascular responses to the rostral ventrolateral medulla (RVLM). In a previous study we showed that blockade of the KF strongly attenuated the short responses and moderately attenuated the long responses to glutamate microinjection into the CnF, suggesting that the cardiovascular effects of the CnF, especially the short responses, were mediated by the KF. In the present study the cellular basis of the cardiovascular responses of the CnF and possible role of the KF in relaying them to the RVLM were explored. In one group, l-glutamate was microinjected in the CnF and the cardiovascular responses were recorded. In another group the single unit responses of the KF to l-glutamate injection into the CnF were recorded. Our results showed that chemical stimulation of the CnF with glutamate produced mainly excitatory cardiovascular and single unit responses and a minority of mixed (excitatory and inhibitory) responses. In about one fourth of the cases there were no responses to stimulation. Various patterns of each group were presented and compared between cardiovascular and single unit responses. Similarities were found between cardiovascular and single unit response patterns, suggesting a significant role of KF neurons in mediating the CnF cardiovascular responses to the RVLM.

There is no report on the cardiovascular effects of the glutamatergic system in the CnF. In the present study, we investigated the cardiovascular effects of glutamate and its NMDA and AMPA/kainate receptors in the CnF. In addition, the possible mediation of Kolliker-Fuse (KF) nucleus in the cardiovascular effects of the CnF was explored. l-glutamate, AP5 (an NMDA receptor antagonist), and CNQX (an AMPA/kainate receptor antagonist) (50-100 nl) were microinjected into the CnF of anesthetized rats. Also, the KF was blocked by cobalt chloride (CoCl(2)) then l-glutamate was microinjected into the CnF. The maximum changes of blood pressure and heart rate were compared with the pre-injection (paired t-test) and control (independent t-test) values. Microinjection of glutamate (25 nmol/100 nl) into the CnF produced either a short pressor and bradycardic or a long pressor and tachycardic responses. Microinjection of AP5 or CNQX alone did not affect the basal arterial pressure and heart rate. However, co-injection of glutamate with AP5 strongly attenuated the short and moderately attenuated the long cardiovascular responses elicited by glutamate. Co-injection of glutamate with CNQX did not attenuate the short and weakly attenuated the long cardiovascular responses elicited by glutamate. These data suggest that the responses are mediated mainly through NMDA receptors. Blockade of the KF nucleus strongly attenuated the short response and weakly attenuated the long response to glutamate microinjection, suggesting that the cardiovascular effects of glutamate in the CnF, especially the short responses, were mediated by the KF nucleus.

    Full Text Available Yenisei inscriptions are inscriptions along the Yenisei River having a total number of 250 and thought to have been erected by the Kyrgyz. Among these inscriptions, although the first discovered one was Uybat III (E 32 Inscription, not much had been known about the characteristics of the alphabet and who they belonged to until the inscriptions remained from the Second East Turkic Khanate was found in 1889 by N. Yadrintsev. After the decipherment of the letters in this alphabet by Thomsen, researches mostly focused on the Mongolian area, and attempts were also made to read these inscriptions. In this sense, we should mention the names Radloff, S. Ye. Malov and H. N. Orkun. None of the Yenisei inscriptions bear a date. Maybe they did not have advanced calendar systems to be used in the inscriptions. The common characteristic of almost every inscription is that they mention, rather than historical events, what the hero of the inscription did, why he died, and longing for family members, homeland, sky and sun as told from his mouth; as a result, they did not caught the attention of researches apart from scientists on Turkish language. In this article, 170 inscriptions, whose texts are available, have been analyzed in detail, and our attention has been devoted to the narrations in the texts which might be dated. It has been attempted to determine at least when a few of the inscriptions were erected Yenisey yazıtları, Yenisey Irmağı boyunca, Kırgızlar tarafından dikildiği sanılan ve bugün toplam sayısı 250’ye yaklaşan yazıtlardır. Bu yazıtlardan Uybat III (E 32 Yazıtı ilk bulunan yazıt olduğu hâlde N. Yadrintsev tarafından 1889 yılında II. Doğu Türk Kağanlığı’ndan kalan yazıtlar bulununcaya kadar bu yazıtların kimlere ait olduğu ve alfabenin niteliği hakkında pek bir şey bilinmiyordu.

    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.

    The use of Spatial Division Multiplexing for Microwave Photonics signal processing is proposed and experimentally demonstrated, for the first time to our knowledge, based on the selective inscription of Bragg gratings in homogeneous multicore fibers. The fabricated devices behave as sampled true time delay elements for radiofrequency signals offering a wide range of operation possibilities within the same optical fiber. The key to processing flexibility comes from the implementation of novel multi-cavity configurations by inscribing a variety of different fiber Bragg gratings along the different cores of a 7-core fiber. This entails the development of the first fabrication method to inscribe high-quality gratings characterized by arbitrary frequency spectra and located in arbitrary longitudinal positions along the individual cores of a multicore fiber. Our work opens the way towards the development of unique compact fiber-based solutions that enable the implementation of a wide variety of 2D (spatial and wavelength diversity) signal processing functionalities that will be key in future fiber-wireless communications scenarios. We envisage that Microwave Photonics systems and networks will benefit from this technology in terms of compactness, operation versatility and performance stability.

    Magnetic Nanocylinders (MNs) result axially parallel and forming triangular arrays immersed in the membrane used to produce them. As the individual magnetization points along each cylinder axis either inward or outward of the membrane plane, the net magnetization of the set is nil. However, a localized and strong enough magnetic field applied over such MNs array can revert the magnetization of individual MNs. This fact opens the possibility to inscribe ferromagnetic patterns (FPs) over the membrane surface as an alternative way to store fixed information. Patterns with different geometrical shapes and also letters under the arial font were tested. In this frame we have studied the total energy per cylinder for FPs within a circular membrane containing a huge amount of MNs. To prevent spontaneous magnetization reversion, with the consequently information lost, we propose a simple stabilization mechanism. - Highlights: ► Theoretical study about patterns inscription on arrays of magnetic nanotubes. ► Proposal as an alternative way to store fixed information. ► Proposal of stabilization mechanism to prevent spontaneous magnetization reversion and information lost.

  4. SRG Inscription in Supramolecular Liquid Crystalline Polymer Film: Replacement of Mesogens

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available The photoinduced surface relief formation via mass transfer upon irradiation with patterned light has long been a subject of extensive investigation. In azobenzene-containing liquid crystalline materials, UV light irradiation that generates the cis isomer leads to the liquid crystal to isotropic photochemical transition. Due to this phase change, efficiency of the mass transfer to generate a surface relief grating (SRG becomes markedly greater. We have previously indicated that azobenzene-colored SRG-inscribed film can be bleached by removing a hydrogen-bonded azobenzene mesogen. However, this process largely reduces the height feature of the SRG corrugation. Herein, we propose an extended procedure where a colorless mesogen is filled successively after the removal of the azobenzene side chain. The process involves four stages: (i SRG inscription in a hydrogen-bonded supramolecular azobenzene material; (ii crosslinking (insolubilization of the SRG film; (iii removal of azobenzene mesogen by rinsing with a solvent, and (iv stuffing the hollow film with a different mesogen. Although the final stuffing stage was insufficient at the present stage, this work demonstrates the possibility and validity of the strategy of mesogen replacement.

    A highly sensitive fiber-optic accelerometer based on detecting the power output of resonances from the core dip is demonstrated. The sensing probe comprises a compact structure, hereby a short section of specific core (with a significant core dip) fiber stub containing a straight fiber Bragg grating is spliced to another single-mode fiber via a core self-alignment process. The femtosecond laser side-illumination technique was utilized to ensure that the grating inscription region is precisely positioned and compact in size. Two well-defined core resonances were achieved in reflection: one originates from the core dip and the other originates from fiber core. The key point is that only one of these two reflective resonances exhibits a high sensitivity to fiber bend (and vibration), whereas the other is immune to it. For low frequency (core mode reflection. Moreover, the sensor simultaneously provides an inherent power reference to eliminate unwanted power fluctuations from the light source and transmission lines, thus providing a means of evaluating weak seismic wave at low frequency.

    A fluoropolymer optical fiber coating based on the thermoplastic copolymer of chlorotrifluoroethylene and vinylidene fluoride is presented. Such coatings can be used as a UV-transparent material for writing single Bragg gratings or arrays of chirped fiber Bragg gratings directly through the fiber coating with the use of excimer laser radiation at 248 nm. As an optimum radiation density that does not lead to significant degradation of the fluoropolymer coating, an exposure time not exceeding 200 s with a 10 Hz laser pulses repetition rate at 70 mJ/cm2 was identified. With such inscription parameters it was possible to inscribe arrays of fiber Bragg gratings in hydrogen-loaded birefringent optical fiber with an elliptical stress cladding through a 12 μm thick coating, so that stripping of the coating is avoided and good mechanical strength is preserved. The reflection spectrum width of the chirped Bragg gratings was about 3.5 nm with a reflectance coefficient of the most effective grating of up to 38%. Such Bragg grating arrays are especially interesting as reflective elements in fiber interferometers.

  14. Seeing Inscriptions on the Shroud of Turin: The Role of Psychological Influences in the Perception of Writing.

    2015-01-01

    The Shroud of Turin (hereafter the Shroud) is one of the most widely known and widely studied artifacts in existence, with enormous historical and religious significance. For years, the Shroud has inspired worldwide interest in images on its fabric which appear to be of the body and face of a man executed in a manner consistent with crucifixion, and many believe that these images were formed in the Shroud's fibers during the Resurrection of Jesus of Nazareth. But, more recently, other reports have suggested that the Shroud also contains evidence of inscriptions, and these reports have been used to add crucial support to the view that the Shroud is the burial cloth of Jesus. Unfortunately, these reports of inscriptions are based on marks that are barely visible on the Shroud, even when images are enhanced, and the actual existence of writing on the Shroud is still a matter of considerable debate. Here we discuss previous evidence concerning the psychological processes involved generally in the perception of writing, and especially when letters and words are indistinct. We then report two experiments in which the influence of religious context on perception of inscriptions was addressed specifically, using an image of woven fabric (modern linen) containing no writing and with no religious provenance. This image was viewed in two different contexts: in the Religious Context, participants were informed that the image was of a linen artifact that was important to the Christian faith whereas, in the non-religious Neutral Context, participants were informed that the image was of a simple piece of linen. Both groups were told that the image may contain faint words and were asked to report any words they could see. All participants detected words on the image, and indicated that these words were visible and were able to trace on the image the words they detected. In each experiment, more religious words were detected in the Religious Context condition than in the Neutral

    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.

  18. Using articulation and inscription as catalysts for reflection: Design principles for reflective inquiry

    Science.gov (United States)

    Loh, Ben Tun-Bin

    2003-07-01

    The demand for students to engage in complex student-driven and information-rich inquiry investigations poses challenges to existing learning environments. Students are not familiar with this style of work, and lack the skills, tools, and expectations it demands, often forging blindly forward in the investigation. If students are to be successful, they need to learn to be reflective inquirers, periodically stepping back from an investigation to evaluate their work. The fundamental goal of my dissertation is to understand how to design learning environments to promote and support reflective inquiry. I have three basic research questions: how to define this mode of work, how to help students learn it, and understanding how it facilitates reflection when enacted in a classroom. I take an exploratory approach in which, through iterative cycles of design, development, and reflection, I develop principles of design for reflective inquiry, instantiate those principles in the design of a software environment, and test that software in the context of classroom work. My work contributes to the understanding of reflective inquiry in three ways: First, I define a task model that describes the kinds of operations (cognitive tasks) that students should engage in as reflective inquirers. These operations are defined in terms of two basic tasks: articulation and inscription, which serve as catalysts for externalizing student thinking as objects of and triggers for reflection. Second, I instantiate the task model in the design of software tools (the Progress Portfolio). And, through proof of concept pilot studies, I examine how the task model and tools helped students with their investigative classroom work. Finally, I take a step back from these implementations and articulate general design principles for reflective inquiry with the goal of informing the design of other reflective inquiry learning environments. There are three design principles: (1) Provide a designated work space

    AbstrActThe importance of the survival of the manuscript folios of the sūtras and tantras in the collection of the Tabo monastery in Himachal Pradesh is well known to the Buddhist scholarly world. Eleven manuscripts of theAvataṃsakasūtra have been identified among the Tabo corpus.1In total, about 90 folios of the four different manuscripts correspond to theGaṇḍavyūhasūtra that belongs to the last section of theAvataṃsakasūtra-corpus. What is interesting to note is that some portions of theGaṇḍavyūhasūtra wall inscriptions are available in the text of the manuscripts that are labelled as T 143 and T 268. The present paper makes an attempt to compare and translate the portions of the text available in manuscript number T 143 and T 268 and wall inscriptions and offers its textual comparison with the Sanskrit texts of theGaṇḍavyūhasūtra.2

    Full text: The stripe sign consist of `the presence on the perfusion image of a VQ lung scan of a stripe of perfused lung tissue between a perfusion defect and the adjacent pleural surface`. In the revised PIOPED criteria, it is predictive of the absence of pulmonary embolism in the area of the sign. This case study involved a 71-year-old woman who presented with left-sided pleuritic chest pain. The perfusion lung scan demonstrated a perfusion defect involving the left posterior and superior basal segments with an associated stripe sign. A repeat LPO view at a more posterior angle and tomography of the lungs failed to demonstrate the stripe. In this case, the stripe sign was an artefact, perhaps `shine through` from the underlying lung. This evidence suggests that before the stripe sign is used to diagnose a patient, it should be apparent on at least two views of differing angles or on tomography.

  10. Çivi Yazılı Hukukta Kölelere Verilen Cezalar Punishments Given To Slaves In Cuneiform Law

    Full Text Available Agricultural activities that came out as a result of permanent settlement also brought about the need for human work force. Thus, slavery as a class arose and this class was composed of people who were under the control of their lords, used as a work force having no freedom. The Ancient Near East societies found the existence of slavery system beneficial for their small scale and closed economy. Thus, they created a class of slaves from war captives, from those who had to transfer their goods and lands as a result of growing poorer due to poor harvest, debtors who did not pay for their debts and from the ones who stood up to their families; thus punished. In order to provide the permanence of this cheap and constant labor force, they proposed certain penal sanctions within the current legal norms attributing some of the behaviors of slaves as guilt. The aim of this study is to present the penal sanctions against the acts of slaves regarded as guilt within the laws. For this aim, the study focused on Ancient Mesopotamian societies and Hittites in Anatolia both having cuneiform legal system. The behaviors requiring punishment according to the legal systems of these ancient societies were: running away from the lord’s house, a woman’s wearing scarf without the permission of her lord, slave’s stealing something and disobeying the lord. Slaves who performed such behaviors were mutilated. Additionally, the people who hide a slave running away from the lord’s house were given capital punishment. İnsanoğlunun yerleşik hayat düzenine geçişiyle birlikte başlayan tarımsal faaliyetler insan iş gücü ihtiyacını da beraberinde getirmiştir. Böylece efendisine bağlı olup, iş gücü olarak yararlanılan ve çeşitli sebeplerden dolayı hürriyetinden yoksun bırakılmış olan insanların oluşturdukları köle sınıfı ortaya çıkmıştır.

    In this paper, we report photo-inscription of uniform Bragg gratings in trans-4-stilbenemethanol-doped photosensitive step-index polymer optical fiber. Gratings were produced at ~1575 nm by the phase mask technique with a femtosecond laser emitting at 400 nm with different average optical powers (8 mW, 13 mW and 20 mW). The grating growth dynamics in transmission were monitored during the manufacturing process, showing that the grating grows faster with higher power. Using 20 mW laser beam power, the reflectivity reaches 94 % (8 dB transmission loss) in 70 seconds. Finally, the gratings were characterized in temperature in the range 20 - 45 °C. The thermal sensitivity has been computed equal to - 86.6 pm/°C.

    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.

  19. The LongPen--the world's first original remote signing device.

    Science.gov (United States)

    Kruger, Diane M

    2010-05-01

    The LongPen is a remote-controlled pen and videoconferencing device conceived by Canadian author Margaret Atwood in 2004 and initially intended to bring "live" author signings to far away locations. The LongPen allows for individually inscribed long distance signatures and writing while maintaining an original record, written with pen and ink. LongPen specimens were compared with control specimens using different speeds, pen pressures, and types of pens. Preliminary indications are that LongPen inscriptions can be identified or associated with their author. Size and form are maintained and artifacts are subtle. Some limitations with respect to the capture of long tapered strokes, delicate connecting strokes, and differences in line width were noted. Factors which may impact forensic handwriting examinations include limited amounts of writing, light pen pressure, date of the writing, type of writing instrument, dimensions of the writing, and failure to consider that the device has been used.

  20. Computational triadic algebras of signs

    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.

    Full Text Available Orkhon Inscriptions are the oldest known written sources ofTurkic writing and they are bengi-stones which give information onTurkish culture, history and way of life. They were written in oratoricalstyle. They consist of information given by Bilge Khagan, Kul Tigin andVizier Tonyukuk on wars fought by the Turks against other tribes andclans; their advices and warnings relating to the survival of Turkishpeoples. They enable us to reach information about Turkish militarytradition, Turks’ perception of sovereignty, state organization, Turkishhistory, culture and customs. These inscriptions, which dated backthirteen centuries, are basis of modern Turkish in terms of sentencestructure, usage of verbs and words. There have been various studieson language characteristics of Orkhon Inscriptions, but no studies weremade directly on language education and training. In this study, theseinscriptions are analyzed in terms of four basic language skills;comprehension and narrative skills. Concepts of reading and listeningskills (comprehension skills and concepts of talking and writing skills(narrative skills are identified and examined. This study is a descriptivestudy and survey model is used. During the survey, term/word-wordgroups, which belong to comprehension and narrative skills, areidentified from the inscriptions. These term/word-word groups areclassified according to sub-categories as reading, listening, talking,writing and are subjected to content analysis. In light of these data,application of comprehension and narrative skills in OrkhonInscriptions are established.

  4. 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.

    Full Text Available Two fragments of white marble are embedded in the apsis’ wall outside the parish church of St. Agatha in Santhià (near Vercelli, in Piedmont: the first one is engraved with the final part of a dedicatory inscription to a martyr by a clergyman named Vvalpertus (or Alpertus; the second one is a part of a small pillar or a lintel coming from a presbytery enclosure, and is decorated with a motif of intertwined gallons. The inscription stayed in the middle of a pluteus bordered by a carved frame, of which only a part of the lower band survives: the letters and the style of the decorations allow a chronology within the 8th century, while the fragment of pillar is to be traced back to a period between the 8th and the first half of the 9th. Of special interest are the Lombard onomastic of the dedicator and, in the final surviving text, the “signature” of a sculptor, which is present in a second inscription of Lombard age found in Piedmont, adorned with carved decorations as well. The analysis of these artefacts - hitherto unpublished - offered the opportunity to restudy two other inscriptions once existing in the church of St. Agatha, long lost and of uncertain authenticity: all these data allow various deductions about the history of Santhià over the centuries of the early Middle ages, the presence of a clergy in the countryside of the diocese of Vercelli, and the work of sculptors and engravers active between the 8th and 9th century in an area between Lombardy, Piedmont, Liguria and Provence, labelled in the past under the unifying name of “bottega delle Alpi Marittime”.

  1. Dialetic Between Islamic Law and Adat Law in the Nusantara: A Reinterpretation of the Terengganu Inscription in the 14th Century

    Directory of Open Access Journals (Sweden)

    Ayang Utriza Yakin

    2015-02-01

    Full Text Available This article discusses the inscription found in Terengganu, which originated in the early XIV Century. The inscription documents the laws implemented by the rulers of the time. These texts reveal that the laws of this time came from two sources: Islamic law and customary (adat law. In other words, the inscription indicates that legal pluralism was already in existence by the 14th Century. Adat law was the principle legal system in place, playing an important role in the archipelagic society at the time. However, there was an alternative system of Islamic law (e.g. stoning as a punishment for adultery in place for lower social classes. This finding suggests that Islamic law was already in existence in the early 14th century—much earlier than the prevailing understanding of the history of Islamic law suggests. The article contributes by providing the new transliteration from Jawi into Latin characters and the new translation from old-Malay into modern English, which are arguably more accurate than the previous work.

    When using parametric cost estimation, it is important to note the possibility of the regression coefficients having the wrong sign. 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.

    Full Text Available The professor of Novorossiysky (Odessa University I. Yu. Timchenko (1863-1939 managed to collect a remarkable library on the history of Mathematics which contained primarily antiquarian books including incunabula and 16th century editions. Various aspects of this valuabe book collection have been studied lately. Books from this dispersed collection have been revealed and examined de visu. Their cataloguing incudes the description of individual book copies in view of their provenance. The purpose of the article is to provide the information on a complex of owners’ recordings and dedicatory inscriptions as well as bookplates left on the books making an attempt to trace the fate of the copies incorporated in the library of the Odessa mathematician. The information collected is considered in the context of the history of Mathematics. Many may characterise both direct and indirect expressions of the readers’ interests in books and reading. The study of provenance records demonstrate that the copies acquired by professor Timchenko used to be in the libraries of a number of men of science – mathematicians, physicists, philologists, etc. The findings of this article enable to enlarge the database of provenance making the practical value and results of the research.

  5. Visual Signs of Ageing

    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?

    Sign data are the signs of signal added to noise. It is well known that a constant signal can be recovered from sign data. In this paper, we show that an integral over variant signal can be recovered from an integral over sign data based on the variant signal. We refer to this as a generalized sign data average. We use this result to derive a Green's theorem for sign data. Green's theorem is important to various seismic processing methods, including seismic migration. Results in this paper ge...

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

    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.

    Arthroscopic examination of the tendon has been described as the "gold standard" for diagnosis of tendinitis of the long head of the biceps (LHB). An arthroscopic finding of an inflamed and hyperemic LHB within the bicipital groove has been described as the "lipstick sign." Studies evaluating direct visualization in diagnosis of LHB tendinitis are lacking. During a 1-year period, 363 arthroscopic shoulder procedures were performed, with 16 and 39 patients prospectively selected as positive cases and negative controls, respectively. All positive controls had groove tenderness, positive Speed maneuver, and diagnostic ultrasound-guided bicipital injection. Negative controls had none of these findings. Six surgeons reviewed randomized deidentified arthroscopic pictures of enrolled patients The surgeons were asked whether the images demonstrated LHB tendinitis and if the lipstick sign was present. Overall sensitivity and specificity were 49% and 66%, respectively, for detecting LHB tendinitis and 64% and 31%, respectively, for erythema. The nonweighted κ score for interobserver reliability ranged from 0.042 to 0.419 (mean, 0.215 ± 0.116) for tendinitis and from 0.486 to 0.835 (mean, 0.680 ± 0.102) for erythema. The nonweighted κ score for intraobserver reliability ranged from 0.264 to 0.854 (mean, 0.615) for tendinitis and from 0.641 to 0.951 (mean, 0.783) for erythema. The presence of the lipstick sign performed only moderately well in a rigorously designed level III study to evaluate its sensitivity and specificity. There is only fair agreement among participating surgeons in diagnosing LHB tendinitis arthroscopically. Consequently, LHB tendinitis requiring tenodesis remains a clinical diagnosis that should be made before arthroscopic examination. Published by Elsevier Inc.

  16. Puusepp's sign--clinical significance of a forgotten pyramidal sign.

    Science.gov (United States)

    Tacik, Pawel; Krasnianski, M; Zierz, S

    2009-12-01

    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.

    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.

  2. Investigating the tool marks on oracle bones inscriptions from the Yinxu site (ca., 1319-1046 BC), Henan province, China.

    Oracle Bone Inscriptions in the Shang dynasty (1600-1046 BC) are the earliest well-developed writing forms of the Chinese character system, and their carving techniques have not been studied by tool marks analysis with microscopy. In this study, a digital microscope with three-dimensional surface reconstruction based on extended depth of focus technology was used to investigate tool marks on the surface of four pieces of oracle bones excavated at the eastern area of Huayuanzhuang, Yinxu site(ca., 1319-1046 BC), the last capital of the Shang dynasty, Henan province, China. The results show that there were two procedures to carve the characters on the analyzed tortoise shells. The first procedure was direct carving. The second was "outlining design," which means to engrave a formal character after engraving a draft with a pointed tool. Most of the strokes developed by an engraver do not overlap the smaller draft, which implies that the outlining design would be a sound way to avoid errors such as wrong and missing characters. The strokes of these characters have different shape at two ends and variations on width and depth of the grooves. Moreover, the bottom of the grooves is always rugged. Thus, the use of rotary wheel-cutting tools could be ruled out. In most cases, the starting points of the strokes are round or flat while the finishing points are always pointed. Moreover, the strokes should be engraved from top to bottom. When vertical or horizontal strokes had been engraved, the shell would be turned about 90 degrees to engrave the crossed strokes from top to bottom. There was no preferred order to engrave vertical or horizontal strokes. Since both sides of the grooves of the characters are neat and there exists no unorganized tool marks, then it is suggested that some sharp tools had been used for engraving characters on the shells.

    Full Text Available "Itis incumbent on Romance scholars to analyze and interpret their exceptionally full stock of linguistic material, using all methods of study at their disposal, working both backward and forward in time. Only thus will Romance linguistics be enabled to do what others expect of it: to serve not only as an end in itself but as a model and training-ground for workers in all fields of historical linguistics." Thus wrote the American scholar, Robert A. Hall, jr. some forty years ago in an essay on the recon­ struction of Proto-Romance. 1 Indeed, the researcher into the history of the Romance languages is faced with, on the one hand, the schemes of reconstruction (essentially based on the principles of the historical comparative method and the often puzzling testimonies of reality found in the sources. Put in other terms, he has the choice of working with an abstract system represented by starred Latin forms that do not belong to any real language or the reality of the mass of postclassical written records that have come down to us to be analyzed and sifted through with a view to discovering evidences of trends toward Romance in phonology, morpho-syntax, and vocabulary. And while there are, no doubt, materials whose meaning in terms of future evolution of the Romance languages is difficult, if not impossible to discover, there is an abun­ dance of those that prelude the future. It is the attention to the future that, I believe, can give reality and life to the large number of forms collected from inscriptions, late writers, and other sources of so-called "Vulgar", i. e. non-literary Latin.

  4. [Reverse Chaddock sign].

    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

  5. Translating Signs, Producing Subjects

    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

    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.

    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.

    This work proposes a design methodology using ergonomics and anthropometry concepts applied to traffic sign and street name sign projects. Initially, a literature revision on cognitive ergonomics and anthropometry is performed. Several authors and their design methodologies are analyzed and the aspects to be considered in projects of traffic and street name signs are selected and other specific aspects are proposed for the design methodology. A case study of the signs of "Street of Antiques" in Porto Alegre city is presented. To do that, interviews with the population are made to evaluate the current situation of signs. After that, a new sign proposal with virtual prototyping is done using the developed methodology. The results obtained with new interviews about the proposal show the user satisfaction and the importance of cognitive ergonomics to development of this type of urban furniture.

    Chvostek's Sign was first described in 1876, as a clinical clue associated with patients who suffered from latent tetany, and is induced by percussion of the angle of the jaw. However, over the years many clinicians have called into question the strength of the association with latent tetany, particularly in paediatric practice. This review examines the variation in techniques used to elicit the sign in studies conducted on this phenomenon in children as well as how differences in the classification of a positive Chvostek's sign have lead to varied reports on the strength of the association. Furthermore, an appraisal of the literature regarding the proposed mechanism of Chvostek's sign is reported alongside analysing other diseases which have been associated with Chvostek's sign to uncover any unifying mechanism for the presence of this clinical sign in children.

    2016-11-01

    Full Text Available Subject of Research.We present comparative results of the chirped Bragg gratings inscription efficiency in optical fiber of domestic production with and without low-temperature hydrogen loading. Method. Chirped fiber Bragg gratings inscription was made by the Talbot interferometer with chirped phase mask having a chirp rate of 2.3 nm/cm used for the laser beam amplitude separation. The excimer laser system Coherent COMPexPro 150T, working with the gas mixture KrF (248 nm, was used as the radiation source. In order to increase the UV photosensitivity, the optical fiber was placed in a chamber with hydrogen under a pressure of 10 MPa and kept there for 14 days at 40 °C. Main Results. The usage of the chirped phase mask in a Talbot interferometer scheme has made it possible to get a full width at half-maximum of the fiber Bragg grating reflection spectrum of 3.5 nm with induced diffraction structure length of 5 mm. By preliminary hydrogen loading of optical fiber the broad reflection spectrum fiber Bragg gratings with a reflectivity close to 100% has been inscribed. Practical Relevance. The resulting chirped fiber Bragg gratings can be used as dispersion compensators in optical fiber communications, as well as the reflective elements of distributed fiber-optic phase interferometric sensors.

    Campbell, Ruth; Woll, Bencie

    2003-01-01

    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?

    This work presents a full generic approach to the detection and recognition of traffic signs. 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

  2. FROM SAUSSURE TO CHARAUDEAU: LANGAUGE SIGN AND DISCOURSE SIGN

    Directory of Open Access Journals (Sweden)

    André Crim Valente

    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.

  3. 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.

  4. 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.

    Leon-Sarmiento, Fidias E; Montoya, María C; Camacho, John E; Bayona-Prieto, Jaime; Bayona, Edgardo

    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.

    2005-05-01

    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.

  18. Signed Networks in Social Media

    CERN Document Server

    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 ...

  19. Classification and function of forest inscriptions: Based on the study of the inscriptions in Suining%护林碑刻的分类及其功能透析——基于绥宁县护林碑刻的考察

    Institute of Scientific and Technical Information of China (English)

    王坤

    2011-01-01

    Based on fieldwork of Suining county forest inscriptions, this paper introduced four types of forest inscriptions forming geomantic omen; demarcation; closing hillsides to facilitate afforestation; old trees protection. Viewing from the aims of these inscriptions, they can be classified into four types: steles built by authorities with rules of mountain forests; inscriptions built by villages for afforestation; inscriptions for delimitation of families' hills; inscriptions built by different societies for trees protection. The forest inscriptions contain not only a wealth of ecological information and ideas of ancient forest protection, but also reflect the local ethnic minorities' system options in the plantation management. The function of forest inscriptions primarily lies in protecting ecological environment and the boundary for forest, declaring punishment regulation of deforestation.%基于实地调查所获取的历代护林碑刻资料,绥宁县护林碑刻从内容上大致可分为风水培植、定界息讼、封山育林、保护歇凉古树四类,从立碑的主体上看主要有官府的山林封禁碑、村寨的育林规约碑、家族的山林分界碑、会社组织的护树告示碑等类型。护林碑刻不仅蕴含丰富的生态信息与历代护林思想,还体现出当地少数民族在人工林经营上的制度性选择。其功能主要体现为传承生态维护理念,稳定宜林地边界,宣示毁林的惩罚规制。

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available The paper refutes the assumption of Petar Miljković-Pepek that the oldest icons in the treasury of Monastery of King Marko were painted between 1395 and 1405, as a gift the Byzantine empress Helena Dragaš made to the monastery so as to ensure a yearly memorial service for her tragically killed father Constantine. The part of the inscription on the icon of St Demetrios, on which the assumption was based, has been differently interpreted here: it is not actually related to empress Helena but to the military title of Thessalonian megalomartyr, like the rest of the inscription.

La secuencia de la construcción del relieve y estuco modelado observada en la crestería, junto con los datos epigráficos, muestra que el Templo VI fue construido en dos fases. La primera incluyó la edificación de la pirámide basal, el santuario y el relieve en la fachada este de la crestería, dedicados por el rey Yihk’in Chan K’awil en 735. En la segunda fase, fechada hacia 766, el templo fue ampliado y adornado con los relieves de las fachadas norte y sur.

The construction sequence of the relief and sculpted stucco observed on the roof comb, combined with epigraphic data, demonstrates that Temple VI was constructed in two phases. The first included the raising of the basal pyramid, the upper sanctuary, and the relief on the eastern façade of the roof comb, dedicated by the king Yihk’in Chan K’awil in 735 A.D. During the second phase, dated to around 766 A.D., the temple was enlarged and adorned with the reliefs on the north and south facades.

    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.

The opinions are widely divided, and no unanimous conclusion has been drawn. Actually this character should be deciphered as "(氵,冃)" equal to "mao" ("冒" or "(氵,冒)") with the meaning "covering," and the "(氵,冃)工," therefore, is identical with "(氵,冒)工" referring to lacquer painters who covered the body of products with a transparent coating of lacquer refined through a special process (the so-called "罩明") . The word "(氵,冃)工" referring to these lacquer painters can also be extended to mean "covering painters 罩工 ." The technology of covering artifacts with transparent lacquer that was "as clear as water" had been widely applied in China by the Han period, as early as more than 2,000 years ago.

    殷墟甲骨卜辞是殷人卜祭诸神的实录,祭祀对象涉及殷代所有神灵。殷人所构筑的天神系统、地祇系统和人鬼系统,生动呈现了上古社会精神世界的一个侧面,奠定了中国传统宗教鬼神世界的基本模式,其造神特征和对自然神祇的尊卑态度也对后世产生了深远影响。%The inscriptions on shells and bones found at the Yin Dynasty ruins are authentic records of practicing divination and offering sacrifices to the gods or ancestors in the Shang Dynasty. With all gods involved, people then developed their own system of Heavens, system of gods of mountains and rivers, and system of an- cestors and ghosts respectively, which vividly presents one picture of spiritual world in the ancient society and makes a basic model of traditional world of gods and ghosts in the religion. That all gods are endowed with and that people's attitudes to the gods have a far-reaching effect on their descendants.

    作为中国造园史上唯一技术专著,计成所著《园冶》在明清众多园林文论中独树一帜。其独特之处就在于,它不仅系统介绍了中国古典园林的诸多技术手法,而且将许多文人造园的思想和理念蕴涵其中。以举例解析为主线,分析了《园冶·题词》等篇的重点论句,并借此探讨《园冶》有关异宜与成法、工匠与主人等问题的基本立场。%As the only summary of classical gardening techniques,Yuan Ye, orCraft of Gardens, by Ji Cheng is very unusual and may be unique in many gardening literary theory of the Ming and Qing Dynasties. Its uniqueness lies in that it not only systematically introduced many of the techniques of Chinese classical gardens, but also contained a lot of literati gardening thoughts and ideas. By example analysis, the paper illustrates the speciifc writing background, and deciphers some of the key discussion in the inscription, and further inquires the fundamental ideology towards the relation of special methods and rules, craftsman and master, etc.

  11. 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.

    Danz, Susanne; Lim, Kay Jin

    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...

    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...

  14. Sign (di)Lemma for Dimension Shifting

    Indian Academy of Sciences (India)

    Nitin Nitsure

    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.

    Science.gov (United States)

    Auriemma, M; Capo, A; Meogrossi, G; Amerio, P

    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.

    Pictographs could be regarded as an easiest analyzable class of the characters with the most rigorous limit in the old“Six Books”. However, the classification issue still looks confusing based on the previous studies. To get a better understanding and study, we drew on previous various ideas and the classification criteria of the pictographs, divided the pictographic characters in the oracle bone inscriptions into single, compound and half-compound characters from the perspective of the traditional configuration, and concerned about the three issues on their classification configuration. This will provide better insights into the trace of the beginnings, as well as lay a strong foundation for the future study on the Oracle pictograph characteristics and primitive thinking embodied by Chinese characters.%象形在旧六书说里本应该是界限最严谨最易分析的一类,但放眼前人的研究,在分类问题上,依然让人感到眩惑。为了对象形字有更好的理解和研究,本文借鉴前人各家分类观点和象形字确定的标准,从传统构形角度,把甲骨文中的象形字分为独体、合体、半合体三种,并关注到了其中从构形角度进行分类需要注意的三个问题。从而更好的溯本追源,为以后甲骨文象形字构形特点的研究和汉字所体现的原始思维研究打下基础。

    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.

  2. A tour in sign language

    CERN Multimedia

    2016-01-01

    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...

  3. 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.

  4. 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...

  5. 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.

    1992-01-01

    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.

    Full Text Available In the recent years many approaches have been made that uses computer vision algorithms to interpret sign language. 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.

    The study of iconicity, defined as the direct relationship between a linguistic form and its referent, has gained momentum in recent years across a wide range of disciplines. In the spoken modality, there is abundant evidence showing that iconicity is a key factor that facilitates language acquisition. However, when we look at sign languages, which excel in the prevalence of iconic structures, there is a more mixed picture, with some studies showing a positive effect and others showing a null or negative effect. In an attempt to reconcile the existing evidence the present review presents a critical overview of the literature on the acquisition of a sign language as first (L1) and second (L2) language and points at some factor that may be the source of disagreement. Regarding sign L1 acquisition, the contradicting findings may relate to iconicity being defined in a very broad sense when a more fine-grained operationalisation might reveal an effect in sign learning. Regarding sign L2 acquisition, evidence shows that there is a clear dissociation in the effect of iconicity in that it facilitates conceptual-semantic aspects of sign learning but hinders the acquisition of the exact phonological form of signs. It will be argued that when we consider the gradient nature of iconicity and that signs consist of a phonological form attached to a meaning we can discern how iconicity impacts sign learning in positive and negative ways.

  12. 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.

    2011-12-01

    Full Text Available At the request of the municipality of Figuig, a team of scientists, working under the supervision of Professor Jean-Pierre Vallat of the University Paris Diderot and the School of architecture Paris-Val-de-Seine, was entrusted with the task of drawing up and inventory and making an analysis of the cultural properties of the oasis. This program has been led in order to assist the local authorities in the preparation of the nomination file for the inscription of the oasis on the World Heritage List. The oasis is regarded as a matter of fact as a cultural landscape, composed by an important cultural heritage, both material and immaterial. Figuig is indeed characterized by a rich architecture, particularly the ksour (fortified villages with mud brick houses. Figuig also comprises a palm grove irrigated by a complex network of canals and “foggaras” (pits. Moreover, all the individual and collectives practices connected to the palm grove and to the ksour constitute an important immaterial cultural heritage. The bulk of scientific data (from archaeological, geographical, historical, anthropological investigations calls for a coherent archiving in order to insure the heritage, environmental and tourism management of the oasis. For this purpose, a GIS would be useful. As a scientific and management tool, the GIS is a precious device which makes it possible to produce thematic (archaeological, historical, touristic, etc. mappings and inventories. In parallel with these scientific initiatives, the training of the various stakeholders in the practice of the GIS is being developed. Individuals from the municipality, the cooperation offices and the tourism sector are thus developing new competencies. In this respect, the GIS should be a shared tool with multiple applications: scientific researches, heritage management, urban development, tourism management, etc. In this context, this paper sets to analyse the stakes, perspectives and applications of the

    The biggest issue for the information scientists is that they highly depend on OBI ( oracle bone inscriptions) experts when they dealing with OBI digitization. OBI experts mainly depend on their experience and knowledge to identify and understand OBI,but these experience are only stored in the minds of the experts,and it is not easy to share these experience and knowledge. Ontology technology was proposed to support sharing and reusing the OBI knowledge. An ontology construction model named " two - way active hinge method" was proposed and a small OBI ontology was built by using this model. Based on " seven steps method" and Hownet, detail steps of OBI ontology construction were described. Applications of OBI ontology such as optimized information retrieval and knowledge reasoning were instructed. The results show that the proposed OBI ontology construction method is feasible and effective.%为减少信息科学工作者在甲骨文数字化工作中对甲骨文专家的依赖,并有效解决甲骨文专家辨识和理解甲骨文的经验知识在知识共享及重用方面的问题,提出了构建甲骨文本体的方案.针对甲骨文的特点及其与现代汉语的内在联系,提出双向活动铰接法的甲骨文本体构建模型,参考7步法和知网的基本描述单位,系统分析了甲骨文本体的构建步骤.在甲骨文本体基础上,实现了优化信息检索及本体推理的应用.研究结果表明,甲骨文本体构建方法是可行的.

  13. 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

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.

    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.

  16. Road Signs for UV-Completion

    CERN Document Server

    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.

    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.

  6. 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...

Ocakların müteahhitler yanında ve onlarla birlikte, doğrudan imparatorluk yönetimince işletilmeye başlanmasıyla, yazıtların biçim ve içeriğinde büyük değişiklikler meydana gelmiştir. Ocakların üretim teknolojisinde, jeolojik şartlardan kaynaklanan bir takım küçük farklılıklar bulunsa da, genelde tüm imparatorluk ocaklarında organizasyonun aynı biçimde şekillendiği imparatorluk yönetimince üretim, denetim ve sevkiyatın bütün mermer ocakları için benzer bir çerçeve içinde düzenlenmiş olduğu anlaşılmaktadır. Abstract The most significant source that sheds light on the history of the quarry activities is, without a doubt, the inscriptions. The information regarding the production date of the stone, the quarry which the stone was produced in, the people who carried out the control operations and the organization and management of the quarries can be obtained through the inscriptions. However such extensive information can be valid if only a well-organized establishment is subjected. Furthermore, while inscriptions are rarely discovered in the quarries, the limited number inscriptions that were attained do not usually include such detailed information, and the content and form can vary due to many different reasons such as weakened government authority, change of ownership and change of management to increase or decrease of production capacity. The tradition of managing imperial quarries trough contractors was abandoned towards the end of the 1st Century and the government control and initiative over production were increased. The information regarding the stone such as the production date, the quarry which stone was produced in, the people who carried out the control operations, the way of organization and management of the quarries can be obtained through the inscriptions. Inscriptions on the tablets can be divided into two groups; inside quarry and outside quarry. A small portion of inside quarry

  8. The Phonetics of Head and Body Movement in the Realization of American Sign Language Signs.

    Science.gov (United States)

    Tyrone, Martha E; Mauk, Claude E

    2016-01-01

    Because the primary articulators for sign languages are the hands, sign phonology and phonetics have focused mainly on them and treated other articulators as passive targets. However, there is abundant research on the role of nonmanual articulators in sign language grammar and prosody. The current study examines how hand and head/body movements are coordinated to realize phonetic targets. Kinematic data were collected from 5 deaf American Sign Language (ASL) signers to allow the analysis of movements of the hands, head and body during signing. In particular, we examine how the chin, forehead and torso move during the production of ASL signs at those three phonological locations. Our findings suggest that for signs with a lexical movement toward the head, the forehead and chin move to facilitate convergence with the hand. By comparison, the torso does not move to facilitate convergence with the hand for signs located at the torso. These results imply that the nonmanual articulators serve a phonetic as well as a grammatical or prosodic role in sign languages. Future models of sign phonetics and phonology should take into consideration the movements of the nonmanual articulators in the realization of signs. © 2016 S. Karger AG, Basel.

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.

    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.

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

    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.

    An inscription,which is believed to be relevant to the commercial waterway of Jiangnan Canal,was un-earthed during the archaeological excavations of Jingkou Lock Site,Zhonghua road,Zhenjiang City;and it is also believed to be set up by the traders of rice and beans in the Fiftieth Year of Kangxi’s Reign(1 71 1).These traders u-nited to appeal to the local government for banning stealing and robbing goods by the bad boatmen of Dantu county ganging up with the local ruffians of Fengzhen,Suzhou Prefecture.Another inscription was also found in Jingkou Stage Site,which was set up by the traders of paper and cotton in the Eleventh Year of Shunzhi’s Reign (1 654). These traders united to appeal to the local government for avoiding being robbed when their boats passed by Suzhou and Jingkou.These two inscriptions indicated that Zhenjiang was an important port and its business was booming in early Qing dynasty.%镇江市中华路京口闸遗址在考古发掘过程中出土一方与江南运河商运有关的示禁碑刻,系康熙五十年(1711年)时米豆商人为禁止镇江府丹徒县不良船户勾结苏州府枫镇的地棍在航运途中盗窃商人货物而集体请求官府竖立。京口驿遗址出土的一方示禁碑刻则是顺治十一年(1654年)时纸布商人为避免船过苏州、京口时货物被抢而请求竖立。这两方碑刻反映了清初镇江的商业繁荣和作为交通枢纽的重要地位。

  13. Generalizing everyday memory: signs and handedness.

    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.

  2. 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.

  7. Working memory, deafness and sign language.

    Rudner, Mary; Andin, Josefine; Rönnberg, Jerker

    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.

  8. 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...

    Certain features of the sagging rope sign recently analysed by Apley and Weintroub (1981) are examined in detail. 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.

  13. 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.

    The first clinically observable sign of an unconsciousness episode (UNCE) serves as the temporal sequence (kinetics) onset point for neurological events occurring during the loss of consciousness, unconsciousness and recovery of consciousness phases of the UNCE. The initial neurologic signs of 212 individuals exposed to gradual (N=114) and rapid (N=98) onset +Gz acceleration stress, inducing the ischemic LOC phase in 83.3±18.6s and 8.89±1.52s; p0.1 for gradual and rapid onset +Gz-stress, respectively. Cerebral autoregulation may play a role in determination of ischemic UNCE induction and recovery. Five signs: loss of muscle control, eyelid closure, eye fixation, upward eye deviation, and muscular twitching occurred at LOC phase onset. The most frequent initial sign of LOC phase onset was loss of muscle control (84% of the episodes), followed by eye fixation (8.5%), and upward eye deviation (6.1%). Signs play a key role in differential diagnosis of syncopal, epileptic, psychogenic and other causes of UNCEs. Sign kinetics may provide insight into localization of the essential components and networks within the cephalic nervous system associated with UNCEs. Copyright © 2017 Elsevier Inc.

  15. [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.

    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.

  17. The Babinski sign--a reappraisal.

    Directory of Open Access Journals (Sweden)

    Kumar S

    2000-10-01

    Full Text Available 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.

  18. 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.

    This article verified that the Tu state mentioned in the oracle inscriptions was the Xia people after the Xia Dynasty had been conquered by Tang, the first king of the Shang Dynasty m c.a. 16th century B.C. The state of Xia, which originated from Yu, was entitled "Xia Hou"; its king was hence called "Xia Hou Di" (Emperor of Xia Hou), e.g."Xia Hou Di Qi". The Xia people, together with the Yin (Shang) people, and the Zhou people, were the so-called "people of San Dai" (Three Dynasties). As mentioned in "Lunyu, Bayi", they founded the states, with the Xia people being associated with the pine, the Yin people with the cypress, and the Zhou people with the chestnut.

    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

    2011-01-01

    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.

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.

    The vital signs of pulse rate, blood pressure, temperature and respiratory rate are the 'nub' of individual patient management. At the programmatic level, vital signs could also be used to monitor the burden and treatment outcome of chronic disease. Case detection and treatment outcome constitute the vital signs of tuberculosis control within the WHO's 'DOTS' framework, and similar vital signs could be adapted and used for management of chronic diseases. The numbers of new patients started on therapy in each month or quarter (new incident cases) are sensitive indicators for programme performance and access to services. Using similar reporting cycles, treatment outcomes for all patients can be assessed, the vital signs being: alive and retained on therapy at the respective facility; died; stopped therapy; lost to follow-up; and transferred out to another facility. Retention on treatment constitutes the prevalent number of cases, the burden of disease, and this provides important strategic information for rational drug forecasting and logistic planning. If case numbers and outcomes of chronic diseases were measured reliably and consistently as part of an integrated programmatic approach, this would strengthen the ability of resource-poor countries to monitor and assess their response to these growing epidemics.

    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.

  14. 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.

  15. Sign ambiguity in the K Sigma channel

    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.

    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.

  17. A Sign Language Screen Reader for Deaf

    Science.gov (United States)

    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.

    To develop a technological tool that improves the initial learning of sign language in hearing impaired children. The development of this research was conducted in three phases: the lifting of requirements, design and development of the proposed device, and validation and evaluation device. Through the use of information technology and with the advice of special education professionals, we were able to develop an electronic device that facilitates the learning of sign language in deaf children. This is formed mainly by a graphic touch screen, a voice synthesizer, and a voice recognition system. Validation was performed with the deaf children in the Filadelfia School of the city of Bogotá. A learning methodology was established that improves learning times through a small, portable, lightweight, and educational technological prototype. Tests showed the effectiveness of this prototype, achieving a 32 % reduction in the initial learning time for sign language in deaf children.

    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.

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.

  7. Cycles and Dynamics on Evolving Signed Digraphs

    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.

    Science.gov (United States)

    Williams, Joshua T; Newman, Sharlene D

    A large body of literature has characterized unimodal monolingual and bilingual lexicons and how neighborhood density affects lexical access; however there have been relatively fewer studies that generalize these findings to bimodal (M2) second language (L2) learners of sign languages. The goal of the current study was to investigate parallel language activation in M2L2 learners of sign language and to characterize the influence of spoken language and sign language neighborhood density on the activation of ASL signs. A priming paradigm was used in which the neighbors of the sign target were activated with a spoken English word and compared the activation of the targets in sparse and dense neighborhoods. Neighborhood density effects in auditory primed lexical decision task were then compared to previous reports of native deaf signers who were only processing sign language. Results indicated reversed neighborhood density effects in M2L2 learners relative to those in deaf signers such that there were inhibitory effects of handshape density and facilitatory effects of location density. Additionally, increased inhibition for signs in dense handshape neighborhoods was greater for high proficiency L2 learners. These findings support recent models of the hearing bimodal bilingual lexicon, which posit lateral links between spoken language and sign language lexical representations.

    We propose a parametrized walk-based measure for the lack of balance in signed networks inspired by the Katz measure of similarity of two vertices in a network. We show that the performance of the proposed measure is marginally better than a recently proposed walk-based measure of the lack of balance for an undirected version of the real-world signed networks: Epinions, Slashdot and WikiElection. The proposed measure can be used to distinguish signed social networks on the basis of their degree of lack of balance. We also establish that cycles of shorter lengths can predict the sign of an edge in these signed networks better than the longer cycles by using the Katz prediction rule.

In the present article, the impetus and rationale for development of the SLSCO is discussed. Previous studies related to classroom signing and observation methodology are reviewed. The procedure for developing the SLSCO is then described. This procedure included (a) interviews with faculty and students at NTID, (b) identification of linguistic features of sign language important for conveying content to deaf students, (c) development of forms for recording observations of classroom signing, (d) analysis of use of the forms, (e) development of a protocol for conducting the SLSCO, and (f) piloting of the SLSCO in classrooms. The results of use of the SLSCO with NTID faculty during a trial year are summarized.

    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.

    2011-01-01

    The Overlap operator fulfills the Ginsparg-Wilson relation exactly and therefore represents an optimal discretization of the QCD Dirac operator with respect to chiral symmetry. When computing propagators or in HMC simulations, where one has to invert the overlap operator using some iterative solver, one has to approxomate the action of the sign function of the (symmetrized) Wilson fermion matrix Q on a vector b in each iteration. This is usually done iteratively using a "primary" Lanczos iteration. In this process, it is very important to have good stopping criteria which allow to reliably assess the quality of the approximation to the action of the sign function computed so far. In this work we show how to cheaply recover a secondary Lanczos process, starting at an arbitrary Lanczos vector of the primary process and how to use this secondary process to efficiently obtain computable error estimates and error bounds for the Lanczos approximations to sign(Q)b, where the sign function is approximated by the Zolo...

    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.

  15. Syntactic priming in American Sign Language.

    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.

    2004-01-01

    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.

    Full Text Available The nullity of a graph is the multiplicity of the eigenvalue zero in its spectrum. A signed graph is a graph with a sign attached to each of its edges. In this paper, we apply the coefficient theorem on the characteristic polynomial of a signed graph and give two formulae on the nullity of signed graphs with cut-points. As applications of the above results, we investigate the nullity of the bicyclic signed graph Γ∞p,q,l, obtain the nullity set of unbalanced bicyclic signed graphs, and thus determine the nullity set of bicyclic signed graphs.

    Full Text Available Mycetoma is a chronic granulomatous disease that is more common in tropical than in temperate regions. Early diagnosis is important due to the therapeutic implications. Although biopsy and microbiological culture provide definitive diagnosis, they are time-consuming procedures and may not be able to provide a definite diagnosis in cases of fastidious organisms. The "dot-in-circle" sign has recently been proposed as a highly specific magnetic resonance imaging (MRI and ultrasonography (USG sign of mycetoma, which may allow a noninvasive as well as early diagnosis. We present a case of histologically proven mycetoma that demonstrated this sign.

    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.

Firstly, an inscription system for the laser into fiber cores was designed using a camera and an electric moving platform. With controlling a pulse laser of 1. 3 Mw, a LPFG was inscribed in a non-hydrogen-loaded bare fiber using point by point technique, and the resonant peak of the LPFG is about -17 Db in the 1200 - 1700 nm band. Then, high temperature sensing experiments were performed on the LPFG by a high temperature box, obtained results show that the linearity of the resonance peak changes is about 0. 992 and temperature sensitivity is 0.056 nm/℃ at 300 - 800℃. It demonstrates that the inscription technology for LPFGs by using the 800 nm femtosecond laser is feasible and obtained LPFGs have good responsecharacteristics and stability, and are suitable for the high-temperature measurement.

    War is the continuation of politics. The military inscriptions of Eastern and Western Zhou Dynasty represented by "the most important state affairs are sacrifice and warfare" indicate the process of sprout and development of original "humanity" values. From the wording of inscriptions then, one thing is clear that there is inheritance as well as obvious changes about warfare concept from Yin Dynasty and Shang Dynasty, namely sacrifice in wars became much more convenient, which aims at consolidating the souls of soldiers. The detailed psychological description paid more attention to the existence and performance of warfare subject as well as the standardization and rationalization of military organization, the specific matters of military management, the warfare efficiency and safeguard, which exemplifies the safety of rights and lives have been strengthened. All those demonstrate along with the escalation of warfare intension in Eastern and Western Zhou Dynasty, the original "humanity" values and the ideology of "cautious resorts to arms" have been further developed and featured.%战争是政治的延续。“国之大事在祀在戎”时代的两周军事铭文揭示了原始“人本”观念的萌芽、发展历程。从其铭文用词可以看出从殷商到两周时期,战争观念有继承,也有较大的改变:祭祀在战争中显得更加简便,意在安慰参与者的心灵世界。具体的心理描写更关注战争主体的存在及其表现,也更重视军队组织的规范化和合理化、军队管理的细节、战争有效性和战争维护,这说明权利安全和生命安全意识得到加强。这些方面都表明两周时期随着战争强度的升级,原始“人本”观念、“慎兵”理念得到了进一步的发展和凸现。

    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.

    Objective: To study the association between the 'dural tail sign' and spinal meningiomas on MR imaging. Methods: Retrospective review of MR examinations of all pathologically proven spinal meningiomas from 1998 to 2005 was performed. Lesions were evaluated for size, signal intensity, enhancement pattern, and presence or absence of dural tail. The dural tail length and direction in reference to the meningioma were also evaluated. Results: Seven spinal meningiomas were identified in seven patients. One lesion was purely extradural, while the remaining were intradural extramedullary. Dural tail was present in four cases (57%) and its length ranged between 5 and 21 mm. The tail was seen cranial and caudal to the meningioma in three cases and only cranially in one. Coronal images were available in three cases and in two of these; the dural tail was clearly depicted. Conclusions: 'Dural tail sign' is as common in spinal meningiomas as in cranial meningiomas.

    We investigate degree correlations in two online social networks where users are connected through different types of links. 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.

    2013-03-01

    We report experimental and theoretical examinations of the peculiarities in Velocity Selective Optical Pumping (VSOP) resonance behavior at open and closed hyperfine transition spectra of Cs atoms (on the D2 line), confined in optical cell with thickness L = 6λ, where λ = 852 nm. For linear and circular polarizations of the irradiating light, open transitions exhibit reduced absorption (fluorescence) VSOP resonances whose contrast increases with atomic concentration and light intensity. However, in case of closed transition the situation is different, the enhanced absorption (fluorescence) VSOP resonance reverses its sign with the atomic concentration and light intensity. Theoretical analysis based on the density matrix formalism, taking into account the statistical tensors describing atomic population and longitudinal alignment, shows that the VSOP resonance sign reversal at the closed transition can be attributed to the efficiency reduction of population transfer by the spontaneous decay with atomic source temperature.

    Full Text Available – Sign language plays a great role as communication media for people with hearing difficulties.In developed countries, systems are made for overcoming a problem in communication with deaf people. This encouraged us to develop a system for the Bosnian sign language since there is a need for such system. The work is done with the use of digital image processing methods providing a system that teaches a multilayer neural network using a back propagation algorithm. Images are processed by feature extraction methods, and by masking method the data set has been created. Training is done using cross validation method for better performance thus; an accuracy of 84% is achieved.

  12. Unusual signs in quantum field theory

    O'Connell, Donal

    Quantum field theory is by now a mature field. Nevertheless, certain physical phenomena remain difficult to understand. This occurs in some cases because well-established quantum field theories are strongly coupled and therefore difficult to solve; in other cases, our current understanding of quantum field theory seems to be inadequate. In this thesis, we will discuss various modifications of quantum field theory which can help to alleviate certain of these problems, either in their own right or as a component of a greater computational scheme. The modified theories we will consider all include unusual signs in some aspect of the theory. We will also discuss limitations on what we might expect to see in experiments, imposed by sign constraints in the customary formulation of quantum field theory.

  16. Influence of gravity upon some facial signs.

    Facial clinical signs and their integration are the basis of perception than others could have from ourselves, noticeably the age they imagine we are. Facial modifications in motion and their objective measurements before and after application of skin regimen are essential to go further in evaluation capacities to describe efficacy in facial dynamics. Quantification of facial modifications vis à vis gravity will allow us to answer about 'control' of facial shape in daily activities. Standardized photographs of the faces of 30 Caucasian female subjects of various ages (24-73 year) were successively taken at upright and supine positions within a short time interval. All these pictures were therefore reframed - any bias due to facial features was avoided when evaluating one single sign - for clinical quotation by trained experts of several facial signs regarding published standardized photographic scales. For all subjects, the supine position increased facial width but not height, giving a more fuller appearance to the face. More importantly, the supine position changed the severity of facial ageing features (e.g. wrinkles) compared to an upright position and whether these features were attenuated or exacerbated depended on their facial location. Supine station mostly modifies signs of the lower half of the face whereas those of the upper half appear unchanged or slightly accentuated. These changes appear much more marked in the older groups, where some deep labial folds almost vanish. These alterations decreased the perceived ages of the subjects by an average of 3.8 years. Although preliminary, this study suggests that a 90° rotation of the facial skin vis à vis gravity induces rapid rearrangements among which changes in tensional forces within and across the face, motility of interstitial free water among underlying skin tissue and/or alterations of facial Langer lines, likely play a significant role. © 2015 Society of Cosmetic Scientists and the Société Fran

  2. [100 years of the Babinski sign].

    Science.gov (United States)

    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.

    Ro, A

    1994-01-01

    A theory of interlanguage (IL) lexicons is outlined, with emphasis on IL lexical entries, based on the HPSG notion of lexical sign. This theory accounts for idiosyncratic or lexical transfer of syntactic subcategorisation and idioms from the first language to the IL. It also accounts for developmental stages in IL lexical grammar, and grammatical variation in the use of the same lexical item. The theory offers a tool for robust parsing of lexical transfer errors and diagnosis of such errors.

    Meuris, Kristien; Maes, Bea; Zink, Inge

    2015-08-01

    The goal of this study was to evaluate a key word signing (KWS) program in which adults with mild to severe intellectual disability (ID) were taught manual signs through their support staff. Our hypothesis was that spontaneous manual sign production of participants would increase significantly after 12 months of implementation of the KWS program. A KWS immersion program was implemented in a facility for adults with ID. First, 8 support workers received 8 hr of training. These KWS ambassadors then taught 2 manual signs per week to their colleagues, who modeled the use of the signs throughout the day in natural interactions with their clients. KWS use in 15 adults with ID and 15 of their support staff was evaluated before the start of the program and at a 12-month follow-up using a narrative task and during spontaneous conversation. Manual sign production of support workers and adults with ID had increased significantly 12 months after the start of the program. The adults with ID were able to express significantly more communicative functions in their narrative language after the intervention and when using KWS. The KWS program was successful and can be applied in similar clinical settings.

  13. Phonological reduplication in sign language: rules rule

    Directory of Open Access Journals (Sweden)

    Iris eBerent

    2014-06-01

    Full Text Available Productivity—the hallmark of linguistic competence—is typically attributed to algebraic rules that support broad generalizations. Past research on spoken language has documented such generalizations in both adults and infants. But whether algebraic rules form part of the linguistic competence of signers remains unknown. 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.

    This paper examines the concept of phonological awareness (PA) as it relates to the processing of American Sign Language (ASL). We present data from a recently developed test of PA for ASL and examine whether sign language experience impacts the use of metalinguistic routines necessary for completion of our task. Our data show that deaf signers exposed to ASL from infancy perform better than deaf signers exposed to ASL later in life and that this relationship remains even after controlling for the number of years of experience with a signed language. For a subset of participants, we examine the relationship between PA for ASL and performance on a PA test of English and report a positive correlation between ASL PA and English PA in native signers. We discuss the implications of these findings in relation to the development of reading skills in deaf children. © The Author 2014. Published by Oxford University Press. All rights reserved.

    2013-12-01

    Full Text Available The article is devoted to research of entropy in language. Complexity of the description of entropy is connected with that it is not a material factor of development of language, because language is not real, but the imaginable category, existing only in humans thinking. For this reason the modern researches devoted to studying and calculating of entropy are concentrated on the speech and text material. For understanding of the idea of entropy of language (not of its speech expression it is necessary to investigate the entropy of structure of objective language, not sets of subjective languages, i.e. language as model. The research has showed that in system of a natural language signs of entropy are such language phenomena as synonimy, polysemanticism, language redundancy, variability of forms, loyalty and flexibility of rules, existence of styles. These signs are detected in comparison with signs of absolutely systematized language system, acting as a hypothesis.  Entropy of such system is reduced to zero. The negentropy as negative entropy is opposed to entropy. Negentropy markers are homonymy, absence of a synonimy, invariancy, strict rules of language, monostyle. DOI: http://dx.doi.org/10.12731/2218-7405-2013-9-58

    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.

    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.

    Map of Yuji (《禹迹圖》) and Map of Huayi (《華夷圖》) , engraved in 1136 A. D. of the Qi period, are among the earliest stone-carving maps in China, which play an important role in the study of the history of maps. From the middle of the Qing dynasty, a large number of scholars have undertaken various researches on the maps. Nevertheless, there still remain some basic problems unsolved. The thesis attempts to expound on the following following four aspects.   Firstly, Map of Yuji and Jia Dan’ s Map of Country and Huayi ( 《海內華夷圖》) have no direct relationship. Secondly, the new trend in the study of Chinese Classics as well as the reform of the traditional examination sysetm nurtured the study of Yu Gong ( 《禹貢》) in the Song dynasty, which served as the internal cause for the origination and wide coping of Map of Yuji. Thirdly, the popularity of Map of Huayi , which inherited from Jia Dan’ s Map of Country and Huayi, stemmed from the distinction between “hua” (華) and “yi” (夷) since the Southern Song dy-nasty. Fourthly, stone-carving Map of Yuji derived from Chang’ an and then spread all over the counrty. The long tradition of stone inscription culture in Chang’ an pro-vided an environment in which such map could originate.

    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.

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.

    Full Text Available A 9-month-old girl presented with a 1-month history of coughing. A chest X-ray (CXR was performed, and the antero-posterior view demonstrated the hilum overlay sign. Furthermore, there was absence of the azygo-oesophageal line and bilateral paraspinal lines. The lateral CXR revealed a posterior mediastinal mass. Subsequently, a computed tomogram of the chest confirmed a posterior mediastinal mass, with calcifications and intraspinal extension consistent with neuroblastoma. Histological analysis confirmed this mass as a neuroblastoma.

    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 cultur...

    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.

    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.

    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].
