No current garbage collector combines space efficiency, low collector times, and mutator (application) locality for contemporaneously allocated objects. For example, free-list allocation coupled with mark-sweep collection achieves space efficiency, but poor mutator locality. On the other hand, contiguous (bump-pointer) allocation with copying collection provides mutator locality but poor space ...
PURPOSE To examine the anatomical variation of normal human collector channel orifices and their relationship with Schlemm's canal. METHODS Ten human anterior segments fixed by immersion or perfusion were dissected radially and further divided by fine dissection into corresponding inner and outer wall segments. The tissues were dehydrated, critical-point dried, sputter coated, and examined by...
A disk pressed from commercial SnO2 powder, sandwiched between two nickel screen current collectors, was used as a lithium-ion secondary anode. Its electrochemical lithium insertion–extraction behavior was investigated by galvanostatic charge–discharge and galvanostatic intermittent titration (GITT) using a microcurrent on one current collector. The transelectrode voltage was measured to monito...
Michael Chen and Kunle Olukotun Computer Systems Lab, Stanford University Abstract In this paper, we introduce a novel garbage collector for Java to be used for processors with speculative threads support like the Hydra chip multiprocessor (CMP). Thread speculation permits parallel execution of sections of sequential code with data dependencies enforced in the hardware, eliminating the need for...
Much recent progress has been made theoretically and computationally towards understanding the importance of conical intersections for chemical reactions. Nonetheless, experimental characterization of conical intersections has proven extremely difficult with one striking exception: the Jahn-Teller conical intersection. This article overviews the fundamental similarity of a variety of conical in...
A recent paper in this journal proposed the conversion of conical intersections to avoided crossings by lowering the symmetry with an optical field. The article also claimed that the characters of nonadiabatic transitions caused by avoided crossings and conical intersections are qualitatively different. The present comment shows that this proposal and this claim result from an incorrect appreci...
In this paper, a multi-objective optimization method is implemented by using of genetic algorithm techniques in order to determine optimum configuration of solar chimney power plant. The objective function which is simultaneously considered in the analysis is output power of the plant. Output power of the system is maximized. Design parameters of the considered plant include collector radius (R...
PURPOSE Cone shape neck is regarded as non-instruction for use (IFU) in most commercial stent graft. However, in real practice, liberal application of endovascular aneurysm repair (EVAR) for outside of IFU happens. We investigate non-adherence to conical neck anatomy in terms of early aneurysmal exclusion results. MATERIALS AND METHODS From January 2010 to December 2013, 105 patients with abd...
Collection of biological particles is the first and critical step for any biological agent detection system. Towards our goal of capturing and detecting airborne biological entities in real time, here we investigate on the design of an electrostatic particle capture system. We report on the capture of airborne 100 nm diameter polystyrene nanoparticles as a model system, in swirling flows under ...
