This paper explores a newly developing direction of machine learning called \socially embedded learning". In this research we have been building an o ce-conversant mobile robot which autonomously moves around in an ofce environment, actively gathers information through close interaction with this environment including sensing multi-modal data and making(More)
OBJECTIVES To compare disease activity and the improvement of disease activity evaluated between by Disease Activity Score 28 using erythrocyte sedimentation rate (DAS28-ESR) and by DAS28 using C-reactive protein (DAS28-CRP) in Japanese patients with rheumatoid arthritis (RA). METHODS Data from 3073 RA patients registered in the large cohort database(More)
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)
INTRODUCTION Interstitial Lung Disease (ILD) is frequently associated with Rheumatoid Arthritis (RA) as one of extra-articular manifestations. Many studies for Human Leukocyte Antigen (HLA) allelic association with RA have been reported, but few have been validated in an RA subpopulation with ILD. In this study, we investigated the association of HLA class(More)
We investigated the induction of T-helper cell subsets during the course of lethal or nonlethal blood-stage Plasmodium yoelii 17X infection in C57BL/6 mice, which are relatively susceptible to these intraerythrocytic parasites. C57BL/6 mice infected with the nonlethal variant (PyNL) showed a moderate level of parasitemia and resolution of primary acute(More)
Parasites morphologically consistent with Anisakis simplex sensu lato collected from the coast of Japan and Western North Pacific Ocean were examined by PCR-RFLP of the ITS region (ITS1, 5.8 subunit rRNA gene and ITS2) and mtDNA cox1. The RFLP patterns of rDNA generated by HinfI and HhaI showed that 100% of the larvae collected from Hokkaido and 94% of(More)
of precise motion, dexterous manipulation, and so forth—capabilities a factory robot requires—the increasingly popular interactive robot must be able to learn from and adapt to its dynamic environment and communicate with people. We have built an office robot, Jijo-2, as a testbed for autonomous intelligent systems that interact and learn in the real world(More)
Mental health management in the workplace has attracted increasing attention in recent years. As sleep is an essential physiological function that is strongly related to mental condition, easy and daily sleep management is considered essential for maintaining good mental health. In this paper, we detected roll-over movements during sleep using a wearable(More)
Cooperative problem solving with resource constraints are important in practical multi-agent systems. Resource constraints are necessary to handle practical problems including distributed task scheduling with limited resource availability. A dedicated framework called Resource Constrained DCOP (RCDCOP) has recently been proposed. RCDCOP models objective(More)
