A Magnetic Bearing Wheel (MBW) with inclined magnetic poles which is composed of six electromagnets and six displacement sensors and enables a 5-DOF magnetic bearing, has been developed. This paper deals with equations of motion of the MBW. In genera

This study demonstrates the isolation performance of a variable-damping isolator using a bio-metal fiber (BMF) valve to enhance the pointing performance of observation satellites by isolating disturbances induced by reaction wheel assemblies. Vibrati

One of the most important issues for microgravity experiments on low-Earth orbiting spacecraft is the “residual acceleration.” The residual acceleration is induced by various kinds of environmental disturbance sources (e. g. gravity gradient, rot

We investigated the role of a mutation of the CXCR4 gene in 11-year-old twin sisters with WHIM syndrome. The mutated gene may result in production of the mutant CXCR4 protein causing abnormal apoptosis and migratory function, which are thought to be

A point mutation (Arg98-->Cys) of exon 3 coding for the extracellular domain of the myelin protein zero (P0) gene was found in a sporadic case of an eighteen year old Japanese man with a severe variant of Charcot-Marie-Tooth disease type 1B (CMT1B).

It has been proposed that T cell activation may play an important role in the pathogenesis of systemic lupus erythematosus (SLE). In order to examine this hypothesis, we assessed the whole degree of clonal accumulation of T cells using RT-PCR and sub
