Vascular endothelial growth factor (VEGF) has previously been shown to display neuroprotective effects following ischemia, suggesting that VEGF may potentially be applied as a neuroprotective agent for the treatment of other neurological diseases. In this study, we investigated the neuroprotective capacity of VEGF in a model of Parkinson's disease. VEGF was(More)
Our Jijo-2 robot, whose purpose is to provide office services, such as answering queries about people's location, route guidance , and delivery tasks, is expected to conduct natural spoken conversation with the office dwellers. This paper describes dialogue technologies implemented on our Jijo-2 office robot , i.e. noise-free voice acquisition system by a(More)
N owadays, robots are moving off of factory production lines and into our everyday lives. 1 Unlike stationary and pre-engineered factory buildings, an everyday environment , such as an office, museum, hospital, or home, is an open and dynamic place where robots and humans can coexist and cooperate. Hence, instead of the capabilities of precise motion,(More)
Distributed resource allocation is an important application of multiagent systems. In this work, we focus on a resource allocation problem that is motivated from a power supply network that contains distributed sources. In the supply network, resources that are initially distributed among source nodes have to be shared among all nodes. The problem is(More)
This paper explores a newly developing direction of machine learning called \socially embedded learning". In this research we have been building an oce-conversant mobile robot which autonomously moves around in an of-ce environment, actively gathers information through close interaction with this environment including sensing multi-modal data and making(More)
We explored the effects of exogenous and endogenous erythropoietin (EPO) in a seizure model of rat. Adult male Fischer 344 rats received continuous intraventricular infusion of EPO dissolved in saline containing 1mg/ml of rat serum albumin, anti-EPO antibody, saline containing 1mg/ml of rat serum albumin or combined EPO and neuropeptide Y (NPY) Y2-receptor(More)
Motion of objects in contact plays an important role in the mechanical assembly by manipulators. This paper presents a motion planning algorithm for the case that a convex polyhedron translates and rotates in contact with another one. The rotation of the moving one is parameterized by the special unitary 2 2 2 matrix to have the algebraic representation of(More)
