The operating characteristics of several phas* -processing receivers for detection of a sine wave in Gaussian noise are deduced both analytically and by simulatirn and compared with optimum processors over a wide range of signal-to-noise ratios. Among the processors considered are (1) the optimum phaseprocessor for small signal-to-noise ratio and known sine wave frequency, (2) the maximum likel...

Neocortical neurons in vivo receive periodic stimuli due to feedforward input from the periphery as well as local cellular and circuit properties. In order to understand how neurons process such information, the responses of neurons to periodic sine wave current stimuli of varying frequencies and amplitudes were investigated. Sine wave stimuli were injected into pyramidal cells of young adult f...

A simple model is studied for the chemotactic movement of biological cells in the presence of a periodic chemical wave. It incorporates the feature of adaptation that may play an important role in allowing for “rectified” chemotaxis: motion opposite the direction of wave propagation. The conditions under which such rectification occurs are elucidated in terms of the form and speed of the chemic...

The recent popularity of touch interfaces equipped in smart phones, tablet PCs, and the like has dramatically increased the opportunities for performing finger operations directly on a touchscreen. In this study, the authors report on experiments in which an actuator is used to perform an operation on a touchscreen surface to express surface unevenness and roughness in order to determine the ra...

Non-collisional heating is an important phenomenon in low-pressure inductively coupled plasmas. In this paper, a self-consistent analytical model for non-collisional heating is developed which shows that non-collisional heating is a warm-electron effect that relies on a resonant interaction of electrons with the electromagnetic wave. Electrons with velocities comparable to the effective wave ph...

The purpose of this study was to develop a method of quantifying the degree of optic disc tilt in normal eyes. This was a prospective, observational cross sectional study of 126 right eyes of 126 healthy volunteers. The optic disc tilt was determined from the circular peripapillary optical coherence tomographic (OCT) scan images. The course of the retinal pigment epithelium (RPE) layer in the p...

We have presented a new hyperbolic auxiliary function method for obtaining traveling wave solutions of nonlinear partial differential equations. Applying this, exact traveling wave solutions for the coupled Sine-Gordon equations are constructed.

In this paper, the Exp-function method is used to obtain generalized travelling wave solutions with free parameters of the MKdV-sine-Gordon and Boussinesq-double sine-Gordon equations. It is shown that the Exp-function method, with the help of any symbolic computation packages, provides an effective mathematical tool for nonlinear evolution equations arising in mathematical physics.

Abstract This paper touches on a sine wave transmitting mode being designed applicable to multichannel high-power electromagnetic transmitters, well explaining the design scheme and working principle of each module. With FPGA as core build hardware platform DSP bridge cooperation between upper computer lower computer, this very amplifies MSK signal provided by external interface with power make...

We recorded the initial vertical vergence eye movements elicited in monkeys at short latency ( approximately 70 ms) when the two eyes see one-dimensional (1D) horizontal grating patterns that are identical except for a phase difference (disparity) of one-quarter wavelength. With gratings composed of single sine waves, responses were always compensatory, showing Gaussian dependence on log spatia...
