We have developed an adaptive real-time road detection application based on Neural Networks for autonomous driving. By taking advantage of the unique structure in road images, the network training can be processed while the system is running. The algorithm employs color features derived from color histograms. We have focused on the automatic adaptation of(More)
PURPOSE Cigarette smoking is the most consistent risk factor for age-related macular degeneration (AMD), especially the choroidal neovascularization (CNV)-mediated exudative type. Dioxins and dioxin-like compounds have various effects on living organisms and are also contained in cigarette smoke. However, the effects of dioxins on the eye remain elusive. In(More)
PURPOSE Sarcoidosis is a chronic multisystem granulomatous disorder characterized by an accumulation of activated CD4+ T cells and monocytes/macrophages in involved organs. Chemokines are required for the extravasation of leukocytes to the inflammation site. This study was undertaken to determine which chemokines are augmented in the serum of patients with(More)
PURPOSE Inducible costimulator (ICOS) is an important costimulatory molecule involved in T-cell activation. In this study, the role of ICOS in the pathogenesis of uveitis in Behçet's disease (BD) was investigated. METHODS Peripheral blood mononuclear cells (PBMCs) were obtained from BD patients with uveitis in the active or remission phase and in healthy(More)
PURPOSE. Sarcoidosis is a chronic multisystem granulomatous disorder characterized by an accumulation of activated CD4 ϩ T cells and monocytes/macrophages in involved organs. Chemo-kines are required for the extravasation of leukocytes to the inflammation site. This study was undertaken to determine which chemokines are augmented in the serum of patients(More)

Progress in algorithm development and transfer of results to practical applications such as military robotics requires the setup of standard tasks, of standard qualitative and quantitative measurements for performance evaluation and validation. Although the evaluation and validation of algorithms have been discussed for over a decade, the research community(More)
PURPOSE Experimental autoimmune uveoretinitis (EAU) is an organ-specific, Th1-cell-mediated disease that targets the neural retina. CCR5 is a chemokine receptor expressed on Th1 cells that promotes their migration. In CCR5-deficient mice, we examined the role of CCR5 in the development of EAU induced by immunization with interphotoreceptor retinoid-binding(More)
Research efforts to achieve the production of artificial seedlings of the Japanese eel Anguilla japonica have progressed in recent decades. However, morphological deformities have been frequently observed in reared leptocephali and glass eels. We examined the effect of water current velocities (5.7–8.3 cm/s) on the body size and morphology of reared(More)
