Vascular smooth muscle cell (SMC) migration and proliferation contribute to neointimal hyperplasia and restenosis after vascular injury. The epoxyeicosatrienoic acids (EETs), which are products of cytochrome P450 (CYP) epoxygenases, possess vasodilatory, antiinflammatory, and fibrinolytic properties. To determine whether these compounds also possess antimigratory and antiproliferative propertie...

The mechanisms by which endotoxins mediate neutrophil transepithelial migration and lung inflammation are unclear. It was hypothesized that both the presence and orientation of epithelial cells are critical to endotoxin-induced neutrophil migration. Neutrophil migration was compared through naked filters and filters with A549 lung epithelial monolayers grown on the upper and lower surface of pe...

This study explores an alternative way of storing text files to answer exact match queries faster. We decompose the original file into two parts as filter and payload. The filter part contains the most informative k bits of each byte, and the remaining bits of the bytes are concatenated in the order of appearance to generate the payload. We refer to this structure as k-bit filtered format. When...

Introduction: In the case that the state-space model class is nonlinear, Kalman filter and RTS smoother breaks down. Although it is always possible to linearize the nonlinear model so that Kalman filter and RTS smoother can still apply approximately, they can be not reliable. On the other hand, stochastic simulation approaches are not limited to linear model classes and can be adopted to draw s...

A K-band second-order bandpass filter with planar inductive p-network using CMOS technology is demonstrated for the first time. To reduce the substrate loss of the filter, the CMOS process compatible backside inductively-coupled-plasma (ICP) deep trench technology is used to selectively remove the silicon underneath the filter. After the ICP etching, a 55.5–92.2% improvement in quality factor i...

The two-stage Kalman estimator was originally proposed to reduce the computational complexity of the augmented state Kalman filter. Recently, it was also applied to the tracking of maneuvering targets by treating the target acceleration as a bias term. Except in certain restrictive conditions, the conventional two-stage estimators are suboptimal in the sense that they are not equivalent to the ...

The Kv2.1 potassium channel contains a lysine in the outer vestibule (position 356) that markedly reduces open channel sensitivity to changes in external [K(+)]. To investigate the mechanism underlying this effect, we examined the influence of this outer vestibule lysine on three measures of K(+) and Na(+) permeation. Permeability ratio measurements, measurements of the lowest [K(+)] required f...

it has been proven through laboratory experiments that the three types of gas migration through a cemented annulus can be eliminated by designing the correct cement mixture. the first type of void and, therefore, gas migration can occur between the casing and the cement. by adding the correct amount of magnetite to the cement, this void, and therefore  the  possible  cause  of  gas migration, c...

texture image analysis is one of the most important working realms of imageprocessing in medical sciences and industry. up to present, different approacheshave been proposed for segmentation of texture images. in this paper, we offeredunsupervised texture image segmentation based on markov random field (mrf)model. first, we used gabor filter with different parameters’ (frequency,orientation) va...
