Parietal epithelial cells (PEC) are major constituents of crescents in crescentic glomerulonephritis. The purpose of these studies was to establish an immortalized PEC cell line with similar characteristics to PEC in vivo for use in future mechanistic studies. Glomeruli were isolated from H-2Kb tsA58 transgenic mice (ImmortoMouse) by standard differential sieving, and several candidate PEC cell...

genomic signal processing is a relatively new field in bioinformatics, in which signal processing algorithms and methods are used to study functional structures in the dna. an appropriate mapping of the dna sequence into one or more numerical sequences enables the use of many digital signal processing tools in the analysis of different genomic sequences. also, a novel influenza a (h1n1) virus o...

Multimedia signal processing (MMSP) refers to of signals from multiple media—speech, audio, images, text, graphics, point clouds, etc.—often jointly. This article reviews the history MMSP and, in parallel, Technical Committee (TC), with a focus on last three decades ( Figure...

Pulsed eddy current (PEC) stimulated thermography is proposed as a powerful non-destructive evaluation (NDE) technique, allowing the operator to observe the heating developed from the eddy current distribution in a structure using infrared imaging, detecting defects over a relatively wide area within a short time. Some defects (impact, delamination, disbond or crack) commonly occur in aerospace...

In Pulsed Eddy Current (PEC) testing, the response feature of one-dimensional magnetic field component, perpendicular to the conductor’s surface, is used to detect and quantify the defects. It is not sufficient for signal interpretation and noise suppression. A novel PEC probe, which consists of a tangential driver-coil and three orthorhombic pickup coils, is introduced in this paper. It is gre...

In this paper we deal from an algorithmic perspective with different questions regarding properly edge-colored (or PEC) paths, trails and closed trails. Given a c-edge-colored graph G, we show how to polynomially determine, if any, a PEC closed trail subgraph whose number of visits at each vertex is specified before hand. As a consequence, we solve a number of interesting related problems. For ...

Photoelectrochemieal etching of n-InAs (Eg = 0.36 eV) is demonstrated. Although the concentration of thermally generated minority carriers and saturation current are high compared to larger bandgap semiconductors, photocurrent to dark current ratios as high as 4:1 were obtained at low temperature (2°C) and at potentials near the flatband potential. A surface film primarily composed of arsenic o...
