In the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized AA6061 aluminum alloy produced by equal channel angular pressing (ECAP) process were investigated. The grain refinement after two passes of ECAP significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. However, the improvement of low cycle fati...

California looks set to permit physician assisted dying next year after its state assembly passed the End of Life Option Act by 43 votes to 34 on 9 September. The legislation is closely modeled on the Oregon law that has permitted terminally ill patients to end their life in that state since 1997. Only patients who file two written requests and have less than six months to live can avail themse...

The existing device driver framework in FreeBSD works fairly well for many tasks. However, there are a few problems that are not easily solved with the current design. These problems include having ”real” device drivers for low-level hardware such as clocks and interrupt controllers, proper resource discovery and management, and allowing most drivers to always probe and attach in an environment...

We have designed a membrane 'staple', which consists of membrane-anchored repeats of the trans-aggregating FM domain that face the lumen of the secretory pathway. In the presence of the disaggregating drug these proteins transit the secretory pathway. When the drug is removed these proteins form electron-dense plaques which we term staples. Unexpectedly, when initially positioned within the cis...

This research examines whether family disruptions (i.e., divorces and separation) contribute to children's weight problems. The sample consists of 7,299 observations for 2,333 children, aged 5-14, over the 1986-2006 period, from a US representative sample from the Child and Young Adult Survey accompanying the National Longitudinal Survey of Youth (NLSY). The study uses individual-fixed-effects ...
