Motivated by a recently developed technique for measuring soft materials properties at the tip of an embedded needle [Zimberlin, et al., Soft Matter, 2007, 3, 763], the mechanics of elasticity- and surface tension-governed void growth within a neo-Hookean material is explored. Previous efforts to describe this technique relied on a hybrid spherical void/spherical cap approximation, thus assumin...

When cells swell in hypo-osmotic solutions, chloride-selective ion channels (Cl(swell)) activate to reduce intracellular osmolality and prevent catastrophic cell rupture. Despite intensive efforts to assign a molecular identity to the mammalian Cl(swell) channel, it remains unknown. In an unbiased genome-wide RNA interference (RNAi) screen of Drosophila cells stably expressing an anion-sensitiv...

This study observes that copper (Cu) films deposited by high current densities or in an aged electrolyte easily generate void defects after chemical mechanical polishing (CMP). The (111)/(200) ratio and the impurity amount of an electroplated Cu film are found to have strong correlation with the formation of void defects. Furthermore, pulse-reverse waveform plating following direct current plat...

This report describes the static and dynamic loading of a 12-inch-wide by 18-inch-deep by 6-foot-long rigid footing, representing the strip footing of a subsurface shelter. Boundary conditions simulated those of a torsionally restrained footing of a flexible arch structure with simulated overburden of 20 feet at one side of the footing. Saturated and partially saturated sand was the test soil. ...

Regulation of swelling-activated Cl(-) current (I(Cl,swell)) is complex, and multiple signaling cascades are implicated. To determine whether protein tyrosine kinase (PTK) modulates I(Cl,swell) and to identify the PTK involved, we studied the effects of a broad-spectrum PTK inhibitor (genistein), selective inhibitors of Src (PP2, a pyrazolopyrimidine) and epidermal growth factor receptor (EGFR)...

We propose a scheduling algorithm minimizing voids generated by arriving bursts in optical burst switched WDM network. In the proposed scheduling algorithm, when the burst which has arrived at optical core router at a certain time can be transmitted in some data channels by using the unused data channel capacity(it is called void), our proposed scheduling algorithm selects the data channel in w...

this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

Micro and nano-scale hydrogel lines can be fabricated on substrates by top-down approaches such as lithography and micro/nano-imprint. When in contact with a solvent, the hydrogel lines swell under the constraint of the substrate, often resulting in distorted shapes or instability patterns. In this paper, using a nonlinear finite element method, the effects of material and geometry on swell ind...

Abstract. The classic characterisation of swell as regular, almost monochromatic, wave trains does not necessarily accurately describe in water bodies shielded from the oceanic climate. In such enclosed areas locally generated waves still contribute to processes at air and seabed interfaces, their presence can be quantified by partitioning components based on speed relative wind. We present sta...
