TR-2015001: A Survey and Critique of Facial Expression Synthesis in Sign Language Animation

Sign language animations can lead to better accessibility of information and services for people who are deaf and have low literacy skills in spoken/written languages. Due to the distinct word-order, syntax, and lexicon of the sign language from the spoken/written language, many deaf people find it difficult to comprehend the text on a computer screen or captions on a television. Animated characters performing sign language in a comprehensible way could make this information accessible. Facial expressions and other non-manual components play an important role in the naturalness and understandability of these animations. Their coordination to the manual signs is crucial for the interpretation of the signed message. Software to advance the support of facial expressions in generation of sign language animation could make this technology more acceptable for deaf people. In this survey, we discuss the challenges in facial expression synthesis and we compare and critique the state of the art projects on generating facial expressions in sign language animations. Beginning with an overview of facial expressions linguistics, sign language animation technologies, and some background on animating facial expressions, a discussion of the search strategy and criteria used to select the five projects that are the primary focus of this survey follows. This survey continues on to introduce the work from the five projects under consideration. Their contributions are compared in terms of support for specific sign language, categories of facial expressions investigated, focus range in the animation generation, use of annotated corpora, input data or hypothesis for their approach, and other factors. Strengths and drawbacks of individual projects are identified in the perspectives above. This survey concludes with our current research focus in this area and future prospects.

Borchert und Beckmann : Biographische Berührungspunkte Wolfgang Borcherts in seinem Drama Draußen vor der Tür

Nachkriegsliteratur, oder Kahlschlags- bzw. Trümmerliteratur wurde zwischen 1945 und 1950 geschrieben. Es war die junge Schriftstellergeneration in der Westzone, die von ihren Erfahrungen mit dem Nationalsozialismus, dem Krieg, dem Leben in Trümmern schrieb. Die Themen dieser Literatur sind demnach Krieg, Tod, Untergang, Gefangenschaft, Trümmer, Heimkehr und Überlebungskampf. Wolfgang Borcherts Drama Draußen vor der Tür ist das wichtigste Beispiel für die Trümmerliteratur und eins der wenigen Dramen, das in der Nachkriegszeit großes Publikum fand. In seinem Drama Draußen vor der Tür, das Borchert einige Monate vor seinem Tod im Jahre 1947 schrieb, geht es um einen Soldaten, Beckmann, der nach 3 Jahren Gefangenschaft in Sibirien in seine zertrümmerte Heimat zurückkehrt. Das Drama wird als ein Protestschrei gegen den Krieg gesehen. Mit Wolfgang Borcherts Lebensgeschichte als Hintergrund entstand die Frage, welche biographischen Berührungspunkte sich in Borcherts Drama Draußen vor der Tür finden lassen, also welche persönlichen Erlebnisse, Erfahrungen, Eigenschaften und Werte werden in seinem Drama widergespiegelt oder zum Ausdruck gebracht.

Canine Subcutaneous Mast Cell Tumors: Cellular Proliferation and KIT Expression as Prognostic Indices

Molecular assays are widely used to prognosticate canine cutaneous mast cell tumors (MCT). There is limited information about these prognostic assays used on MCT that arise in the subcutis. The aims of this study were to evaluate the utility of KIT immunohistochemical labeling pattern, c-KIT mutational status (presence of internal tandem duplications in exon 11), and proliferation markers-including mitotic index, Ki67, and argyrophilic nucleolar organizing regions (AgNOR)-as independent prognostic markers for local recurrence and/or metastasis in canine subcutaneous MCT. A case-control design was used to analyze 60 subcutaneous MCT from 60 dogs, consisting of 24 dogs with subsequent local recurrence and 12 dogs with metastasis, as compared to dogs matched by breed, age, and sex with subcutaneous MCT that did not experience these events. Mitotic index, Ki67, the combination of Ki67 and AgNOR, and KIT cellular localization pattern were significantly associated with local recurrence and metastasis, thereby demonstrating their prognostic value for subcutaneous MCT. No internal tandem duplication mutations were detected in exon 11 of c-KIT in any tumors. Because c-KIT mutations have been demonstrated in only 20 to 30% of cutaneous MCT and primarily in tumors of higher grade, the number of subcutaneous MCT analyzed in this study may be insufficient to draw conclusions on the role c-KIT mutations in these tumors.

Encurtamento pelo frio de fibras musculares oxidativas de bovinos pela técnica de NADH-TR

Carcaças bovinas resfriadas rapidamente podem apresentar uma contração muscular conhecida como encurtamento pelo frio. Esse fenômeno, prejudicial à textura da carne, ocorre principalmente nas fibras musculares oxidativas. O objetivo deste trabalho foi disponibilizar uma ferramenta analítica para distinguir essas fibras e determinar com maior precisão a contração do tecido muscular pela mensuração do comprimento dos sarcômeros. Amostras do músculo Longissimus dorsi de 12 novilhas nelore foram coletadas. As amostras obtidas de uma das meias-carcaças foram submetidas a uma refrigeração rápida, e as amostras provenientes da outra meia-carcaça à refrigeração lenta. Foi testado um método analítico, baseado na técnica de coloração por Nicotinamida Adenina Dinucleotídeo - Tetrazolium Redutase (NADH-TR), para mensurar, por microscopia, o comprimento dos sarcômeros das fibras vermelhas. Foram determinadas as velocidades de queda de pH e temperatura, a área do olho de lombo (AOL) e a força de cisalhamento. Os resultados demonstraram que a temperatura é o principal fator responsável pelo comprimento do sarcômero quando a velocidade de resfriamento é rápida, sendo essa influência menor quando a queda de temperatura é mais lenta. Desta forma, demonstrou-se que a técnica de coloração com NADH-TR é capaz de detectar a ocorrência do encurtamento pelo frio nos músculos esqueléticos de bovinos.

Evaluation of a novel kit (TF-test) for the diagnosis of intestinal parasitic infections

Intestinal parasitic infections are currently a source of concern for Public Health agencies in developing and developed countries. Since three ovum-and-parasite stool examinations have been demonstrated to provide sensitive results, we designed a practical and economical kit (TF-Test) that is now commercially available (Immunoassay Com. Ind. Ltda., S (a) over tildeo Paulo, Brazil). This kit allows the separate collection of three fecal specimens into a preservative solution. The specimens are then pooled, double-filtered, and concentrated by a single rapid centrifugation process. The TF-Test was evaluated in four different laboratories in a study using 1,102 outpatients and individuals living in an endemic area for enteroparasitosis. The overall sensitivity found using the TF-Test (86.2-97.8%) was significantly higher (P<0.01) than the sensitivity of conventional techniques such as the Coprotest (NIL Comercio Exterior Ltda, São Paulo, Brazil) and the combination of Lutz/Hoffman, Faust, and Rugai techniques (De Carli, Diagnostico Laboratorial das Parasitoses Humanas. Metodos e Tecnicas, 1994), which ranged from 48.3% to 75.9%. When the above combined three specimen technique was repeated with three specimens collected on different days, its sensitivity became similar (P > 0.01) to that of the TF-Test. The kappa index values of agreement for the TF-Test were consistent (P < 0.01), being higher and ranking in a better position than conventional techniques. The high sensitivity, cost/benefit ratio, and practical aspects demonstrate that the TF-Test is suitable for individual diagnosis, epidemiological inquiries, or evaluation of chemotherapy in treated communities.

Cholinesterase measurements with an automated kit

Background the Test-mate kit determines acetylcholinesterase (AChE, EC 3.1.1.7) and hemoglobin content of a drop of blood, displaying enzyme activities normalized to 25degreesC. Previous models produced inconsistent results at different temperatures. This report focuses on the current model, ChE 400, and two instruments of a previous OP model.Methods AChE activities were determined by the Ellman assay, using the three kits and a 96-well microplate reader Temperatures ranged from 10 to 37degreesC. Fetal bovine serum was the source of AChE.Results Normalized activities decreased below 20degreesC in the ChE model and below 25 C in the OP models. Activities of the same serum sample differed between the three Test-mate kits, ranging from 1.03 to 1.49 mumoles/min/ml. Percent errors were greater than with the microplate reader at all temperatures.Conclusions Neither we nor the manufacturer recommend the current Test-mate model for fieldwork. Nevertheless, there have been field measurements with Test-Mate kits, and we recommend that an enzyme activity standard be run in parallel with their use. (C) 2002 Wiley-Liss, Inc.
