quaternary ammonium compounds (qacs) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. qacs also cause cell death by protein denaturation . one of the qac is cetyl trimethyl ammonium bromide (ctab) that appears to rapture the cell membrane. the primary site of action of ctab has been suggested to be the lipid components...

The properties of Na channels of the node of Ranvier are altered by neutral, amine, and quaternary local anesthetic compounds. The kinetics of the Na currents are governed by a composite of voltage- and time-dependent gating processes with voltage- and time-dependent block of channels by drug. Conventional measurements of steady-state sodium inactivation by use of 50-ms prepulses show a large n...

Impulsivity and food craving have both been implicated in overeating. Recent results suggest that both processes may interactively predict increased food intake. In the present study, female participants performed a Go/No-go task with pictures of high- and low-calorie foods. They were instructed to press a button in response to the respective target category, but withhold responses to the other...

We propose novel discrete cosine transform (DCT) pseudophase techniques to estimate shift/delay between two one-dimensional(1-D) signals directly from their DCT coefficients by computing the pseudophase shift hidden in DCT and then employing the sinusoidal orthogonal principles, applicable to signal delay estimation remote sensing. Under the two-dimensional (2-D) translational motion model, we ...

Dendritic cells (DCs) are potent professional antigen presenting cells (APC) that activate naïve T cells. Interaction of ICAM-1 and LFA-1 molecules on each cell is required for T cell conjugation to DCs, which leads to naïve CD4+ T cell activation and proliferation. Nanoparticles capable of blocking LFA-1/ICAM-1 interaction were studied as inhibitors of T cell conjugation to DCs. Primary DCs we...

We present upper and lower bounds on the minimum Euclidean distance dEmin(C) for block coded PSK. The upper bound is an analytic expression depending on the alphabet size q, the block length n and the number of codewords jCj of the code C. This bound is valid for all block codes with q 4 and with medium or high rate codes where jCj > (q=3). The lower bound is valid for Gray coded binary codes o...

The recovery of depth from defocus involves calculating the depth of various points in a scene by modeling the effect that the focal parameters of the camera have on images acquired with a small depth of field. In this paper, we propose a method that, instead of analyzing an image region in isolation, uses a block shift-variant interactive blur model to account for the interaction among neighbo...

This paper proposed a novel Block based Mean Shift Image Segmentation Algorithm to significantly reduce the computation and improve the segmentation accuracy for high resolution Medical Image. One of the challenging tasks in the image analysis and computer vision area is to correctly classify the pixels as there are no crisp borders among entities in an image. In this proposed methodology, it i...

We propose a new single-RF Differential Space-Time Block Coding using Index Shift Keying (DSTBC-ISK), which is the first in the family of Differential Space-Time Modulation (DSTM) schemes that can simultaneously achieve the following three imperative objectives of (1) forming a finite-cardinality transmit-signals set under the matrix multiplications of differential encoding; (2) retaining a sin...

Various separation properties of shift spaces have been defined in the literature. In [BPS], several were put into a chain of strict implications, leaving one open question: Is the uniform filling property (UFP) a strictly weaker condition than strong irreducibility (SI)? We given an example to show that it is, and we show that UFP and SI are equivalent for two-dimensional square filling shifts...
