Plant lignans are diphenolic compounds widely present in vegetables, fruits, and grains. These compounds have been demonstrated to have protective effect against cancer, hypertension and diabetes. In the present study, we showed that two lignan compounds, kobusin and eudesmin, isolated from Magnoliae Flos, could modulate intestinal chloride transport mediated by cystic fibrosis transmembrane co...

A flexible electrometer method for measuring the gate capacitances of smafl-geometry MOS transistors is described. This technique applies to standard test transistors without requiring any on-chip circuitry. Subfemtofarad accuracy and high resolution (better than 0.1 fF) have been achieved. This technique permits flexibility with regard to choices of dc biases and test devices and provides a go...

Dihydropyridine-sensitive, voltage-activated calcium channels respond to membrane depolarization with two distinct modes of activity: short bursts of very short openings (mode 1) or repetitive openings of much longer duration (mode 2). Here we show that both the dihydropyridine, BayK8644 (BayK), and the inhibitor of SerThr protein phosphatases, okadaic acid, have identical effects on the gating...

The effect of a single radiation defects cluster formation on the characteristics short-channel structures was studied. Estimates nuclear particle energy, capable forming defects, causing failure and modern silicon transistors with various channel sizes. Keywords: short transistor, defect cluster, event.

As CMOS electronic devices are continuously shrinking to nanometer regime, leads to increasing the consequences of short channel effects and variability due to the process parameters which lead to cause the reliability of the circuit as well as performance. To solve these issues of CMOS, FINFET is one of the promising and better technologies without sacrificing reliability and performance for i...

Introduction: Multipath propagation characteristics for indoor radio channels has recently attracted tremendous attention. There have been attempts to study the statistics of the multipath spread and to model the indoor radio channel.’-5 The effects of short time variations in the delay spread and power, caused by human traffic around a transmitter and receiver, has not yet been thoroughly inve...

With the ever-increasing demands for integration of advanced electronic functions into large-area electronics, down-scaling of thin-film transistors (TFTs) becomes very necessary. The key device operational issues associated with TFT scaling, including short-channel effects (SCEs) and self-heating, are considered in this paper. Device structure engineering approaches are introduced to suppress ...

SNTs (surrounding-gate nanowire transistors) are good candidates to implement low power electronic devices. They provide full gate control over the channel and minimize short channel effects. Design of a high-speed opamp is presented in this paper. It consists of two amplifying stages and an output buffer and is frequency compensated for stable operation. Transistors used have 10nm channel leng...

The mode of inhibition of endplate currents by four esters of 1,1-dimethyl-3-oxybutyl phosphonic acid with different lipophilicities and molecule lengths were estimated by mathematical modeling based on previous electrophysiological data supplemented by several experiments with rhythmic stimulation. The aim was to discriminate between their receptor and non-receptor effects. It was shown that a...

Wavelet analysis based on image enhancement technique is only applicable to black-and-white image, and pseudo-color image processing technology cannot adequately deal with some of the details information of the image. In this paper, an enhanced approach of remote sensing image based on orthogonal wavelet analysis and pseudo-color image processing is presented. Enhanced remote sensing image has ...
