The project presents a new locomotion interface for virtual environment with large display system. Users will be able to direct and control the traveling in the VE by in-place stepping and turning actions. Using a turntable technology, Visual feedback is continuously provided though the use of screen of limited size.
Killer cell lectin-like receptor G1 (KLRG1) is an inhibitory receptor expressed on subsets of natural killer (NK) cells and T cells, for which no endogenous ligands are known. Here, we show that KLRG1 binds three of the classical cadherins (E-, N-, and R-), which are ubiquitously expressed in vertebrates and mediate cell-cell adhesion by homotypic or(More)
The purpose of this paper is to emphasize the importance the consistency between the distance measures on prototype setting and discrimination in elastic matching (EM)-based recognition. Specifically, this paper focuses on the following points: (i) confirmation of performance degradation when Euclidean distance is used on prototype setting whereas(More)
Leguminous lectins have a conserved carbohydrate recognition site comprising four loops (A-D). Here, we randomly mutated the sequence and length of loops C and D of peanut agglutinin (PNA) and expressed the proteins on the surface of mouse green fluorescent protein (GFP)-reporter cells. Flow cytometry, limiting dilution, and cDNA cloning were used to screen(More)
Pemphigoid gestationis (PG) is a rare, perinatal, autoimmune, and blistering dermatosis. Only few cases of PG involving hydatidiform moles have been reported. Complete hydatidiform moles are usually evacuated by dilatation and curettage. We report a patient with a massive complete hydatidiform mole that underwent spontaneous expulsion; she subsequently(More)
LPS consists of a relatively conserved region of lipid A and core oligosaccharide and a highly variable region of O-antigen polysaccharide. Whereas lipid A is known to bind to the Toll-like receptor 4 (TLR4)-myeloid differentiation factor 2 (MD2) complex, the role of the O-antigen remains unclear. Here we report a novel molecular interaction between(More)
