Proposing a speech to gesture translation architecture for Spanish deaf people.

This article describes an architecture for translating speech into Spanish Sign Language (SSL). The architecture proposed is made up of four modules: speech recognizer, semantic analysis, gesture sequence generation and gesture playing. For the speech recognizer and the semantic analysis modules, we use software developed by IBM and CSLR (Center for Spoken Language Research at University of Colorado), respectively. Gesture sequence generation and gesture animation are the modules on which we have focused our main effort. Gesture sequence generation uses semantic concepts (obtained from the semantic analysis) associating them with several SSL gestures. This association is carried out based on a number of generation rules. For gesture animation, we have developed an animated agent (virtual representation of a human person) and a strategy for reducing the effort in gesture animation. This strategy consists of making the system automatically generate all agent positions necessary for the gesture animation. In this process, the system uses a few main agent positions (two or three per second) and some interpolation strategies, both issues previously generated by the service developer (the person who adapts the architecture proposed in this paper to a specific domain). Related to this module, we propose a distance between agent positions and a measure of gesture complexity. This measure can be used to analyze the gesture perception versus its complexity. With the architecture proposed, we are not trying to build a domain independent translator but a system able to translate speech utterances into gesture sequences in a restricted domain: railway, flights or weather information

THE LIFE HISTORY AND DEVELOPMENT OF HYPOGLOSSUM RHIZOPHORUM (DELESSERIACEAE, RHODOPHYTA) IN CULTURE, A NEW DEEP-WATER SPECIES FROM THE CARIBBEAN 1

Hypoglossum rhizophorum sp. nov. is described from deep coral reef habitats on the southern insular shelf of Puerto Rico and the western insular shelf of Basse Terre, Guadeloupe, occurring from 21 to 85 m in depth. The new species is also known from a single shallow-water collection in Hawaii. Plants grow from a prostrate nonfoliose rhizome producing simple, delicate erect blades at regular intervals. Reproductive plants were not collected in the field; isolated plants, however, readily reproduced in culture demonstrating a typical “Polysiphonia - type” life history. Spermatangial sori form coalesced oblique bands which are interrupted by secondary cell rows. Tetrasporangia are produced from both lateral and transverse pericentral cells, adjacent second- and third-order cells as well as cortical cells .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65860/1/j.1529-8817.1988.tb04449.x.pd

<ORIGINAL ARTICLE>Characterization of a new coagulant enzyme isolated from Trimeresurus okinavensis (Himehabu snake) venom

A potent, proteinaceous inducer of coagulation factors, has been purified to homogeneity from Trimeresurus okinavensis (Himehabu snake) by ion exchange chromatography and molecular sieving. It has an apparent molecular weight of 28,000 and it specifically converts fibrinogen to fibrin through an enzymatic reaction. This activity was confirmed by a method using synthetic substrate S-2238, though the fraction from a DEAE sephacel column chromatography shows amidolytic activity of S-2251 and S-2366, which are commonly used to measure plasmin and activated protein C activity, respectively, as well as S-2238. This thrombin-like activity of the final product was not affect by the addition of heparin and AT-III. This enzyme also aggregates normal platelets. It is considered that this purified enzyme would be useful as a hemostatic agent or research reagent

鉄粉層内蔵ばね型アクチュエータの研究

A new spring type actuator is presented in which controls are possible by using usual control methods such as PID control. The actuator consists of a usual helical coil spring and a number of iron (ferrite) particle layers inside. The iron layers are made of silicon based adhesive material involving iron particles. The layers are pasted to the coil spring with a certain air gap between each layer. To achieve both extensive and compressive motions, a permanent magnet is attached to the top of the spring and electromagnet to the base, and the motion of the top of the actuator is controlled by electric currents in the coil of the electromagnet. Amethod of forming the actuator is presented, and its design formulae are presented. The present actuator works well under the control. Especially, the size is small in comparison with such as moving coil actuators, the work area is large enough, and the controlled accuracy is sufficient under the position- and vibration-control.学位記番号：工博甲33

Automatic Categorization for Improving Spanish into Spanish Sign Language Machine Translation

This paper describes a preprocessing module for improving the performance of a Spanish into Spanish Sign Language (Lengua de Signos Espanola: LSE) translation system when dealing with sparse training data. This preprocessing module replaces Spanish words with associated tags. The list with Spanish words (vocabulary) and associated tags used by this module is computed automatically considering those signs that show the highest probability of being the translation of every Spanish word. This automatic tag extraction has been compared to a manual strategy achieving almost the same improvement. In this analysis, several alternatives for dealing with non-relevant words have been studied. Non-relevant words are Spanish words not assigned to any sign. The preprocessing module has been incorporated into two well-known statistical translation architectures: a phrase-based system and a Statistical Finite State Transducer (SFST). This system has been developed for a specific application domain: the renewal of Identity Documents and Driver's License. In order to evaluate the system a parallel corpus made up of 4080 Spanish sentences and their LSE translation has been used. The evaluation results revealed a significant performance improvement when including this preprocessing module. In the phrase-based system, the proposed module has given rise to an increase in BLEU (Bilingual Evaluation Understudy) from 73.8% to 81.0% and an increase in the human evaluation score from 0.64 to 0.83. In the case of SFST, BLEU increased from 70.6% to 78.4% and the human evaluation score from 0.65 to 0.82

Renoprotective Action of a Matrix Metalloproteinase Inhibitor in Progressive Mesangioproliferative Nephritis

Background/Aim: Matrix metalloproteinases (MMPs) play pivotal roles in extracellular matrix turnover and are involved in chronic kidney disease. The renoprotective action of a synthetic MMP inhibitor, compound A, was investigated in chronic nephritis. Methods: Nephritis was induced by a single injection of anti-Thy1.1 antibody to unilaterally nephrectomized rats. The effects of compound A on proteinuria, blood urea nitrogen, and matrix-related gene expressions were evaluated. Collagen accumulation, as assessed by periodic acid-Schiff staining and hydroxyproline content, was determined. The integrity of glomerular epithelial cells and glomerular basement membrane was evaluated with desmin immunohistochemistry and electron microscopic detection of anionic charge sites, respectively. Results: Treatment with compound A notably attenuated proteinuria, ameliorated blood urea nitrogen, and prevented glomerulosclerosis. Gene upregulation of collagen and transforming growth factor β1 in the cortex was prevented in the treated animals. Glomerular epithelial cell injury was milder, and glomerular basement membrane anionic sites were protected with the treatment. Conclusion: A novel MMP inhibitor, compound A, exerts protective effects in progressive glomerulonephritis. Compound A ameliorates various aspects of renal injuries and may have therapeutic potential toward kidney diseases
