The degenerin/epithelial sodium channel (DEG/ENaC) protein family includes related ion channel subunits from organisms ranging from the simple nematode Caenorhabditis elegans to humans. Members of this protein family have been implicated in functions as diverse as touch transduction and proprioception [1–4], pain sensation and maintenance of sodium balance [5]. Several blocks of sequence are co...

light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...

This article presents an automatic digital unbalanced impedance bridge for comparing two-port impedances: R-R, R-C and C-C. The consists of a two-channel source voltage sinusoidal waveforms supplying the arms three-channel precise digitizer, by means which complex ratio output voltages relative are determined. hardware implementation is based on relatively inexpensive universal data acquisition...

Phase interrogation surface plasmon resonance (SPR) imaging is, in principle, suitable multiple samples and high-throughput detection, but the refractive index difference of various can be largely varied, while dynamic range phase SPR is narrow. So it difficult to perform multi-sample detection mode. In this paper, we successfully designed a multi-channel sensing scheme based on common optical ...

an aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation) direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation) direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometr...

Goals: The main purpose of this work is to develop a methodology for determining the parameters signals with multi-position phase manipulation (M-PSK), in which become relatively invariant frequency distortions marine environment. distortion caused by uneven response attenuation part technique assess effect on noise immunity reception. To do this, error probabilities M-PSK signal receiver are d...

Absfract -Signal sets are identified that maximize the cutoff rate region for a multiple-access channel with an additive white Gaussian noise, in which the demodulator output alphabet is allowed to he infinite (“infinitely soft decisions”). The optimizing designs consist of a simplex signal set for each sender, such that each sender’s set is orthogonal to those of the other senders. For “second...
