The authors have developed a wet, band-gap-selective, photoelectrochemical etching process capable of producing cantilever microelectromechanical systems from InGaN/GaN heterostructures. Fabricated cantilevers were successfully actuated, and resonance spectra were measured. The as-grown strain gradient in the GaN film was found to relax upon removal, resulting in upward curvature of the cantile...

Partially isolated cortex ("undercut") is an animal model of posttraumatic epileptogenesis. The surgical procedure involves cutting through the sensorimotor cortex and the underneath white matter (undercut) so that a specific region of the cerebral cortex is largely isolated from the neighboring cortex and subcortical regions(1-3). After a latency of two or more weeks following the surgery, epi...

effect of these poems, as well as the two entitled "barbiturate ingestion," is to lessen somehow the significance that we as physicians ascribe to death while at the same time broadening our understanding of it. Equally important in creating an ironic tone is the style of the poetry with its sharp juxtaposition of medical terminology and human emotion, each serving to undercut the solemnity but...

In this paper we propose a new capital allocation method based on the idea of Sherris (2006). The proposed method explicitly accommodates the notion of limited liability of the shareholders and can further decompose the allocated capital, so that each stakeholder can have a clearer understanding of their contribution. We also challenge the no undercut principle, one of the widely accepted alloc...

Concurrent planning-working with families toward reunification while developing alternative permanency plans--was designed to fit an out-of-home care population much like that projected for the year 2000 and beyond: very young, chronically neglected children from multiproblem families. As large-scale programs begin to develop nationally, those implementing concurrent planning must be aware of t...

block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. in such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. in this paper, first, a brief review of previous studies on toppling failures is presented. then, the physical and mechanical properties of experimental mode...
