BACKGROUND/OBJECTIVE The authors previously developed a passive instrumented arm orthosis (Therapy Wilmington Robotic Exoskeleton [T-WREX]) that enables individuals with hemiparesis to exercise the arm by playing computer games in a gravity-supported environment. The purpose of this study was to compare semiautonomous training with T-WREX and conventional semiautonomous exercises that used a ta...

This paper gives a complete primary decomposition of the first, that is, the smallest, Mayr-Meyer ideal, its radical, and the intersection of its minimal components. The particular membership problem which makes the Mayr-Meyer ideals’ complexity doubly exponential in the number of variables is here examined also for the radical and the intersection of the minimal components. It is proved that f...

This World of Words assignment was an exercise in enhanced lexical analysis and applied analytical thinking. Drawing upon the skills, insights, and research methods rehearsed over a series of short writing assignments, students were asked to compose a five-page analysis of a selected lexeme that examined its past and present histories, as well as its future possibilities. In “The ‘Feminine’ Ide...

A search for excited quarks is performed using the full ep data sample collected by the H1 experiment at HERA, corresponding to a total integrated luminosity of 475 pb. The electroweak decays of excited quarks q → qγ, q → qZ and q→qW with subsequent hadronic or leptonic decays of the W and Z bosons are considered. No evidence for first generation excited quark production is found. Mass dependen...
