In this letter, a new two-parametric pulse that outperforms state-of-the-art pulses with the best performance in terms of BER is proposed, which studied frequency and time domain characteristics. Specifically, based on inverse-hyperbolic functions acsch asech are used for first an ISI-free pulse, its design depends only roll-off factor timing jitter parameter (i.e., design). Finally, proposed s...

This tutorial paper presents an annotated overview of existing hardware implementations of Artificial Neural Systems based on “Pulse Stream” modulations. Pulse Streams are quasi-periodic binary waveforms which convey analog information on waveform timing. The theoretical bases of Pulse Stream computation are shown for the major techniques, and basic circuits are briefly described for most Neura...

A novel method was developed to separate the 238 U fission contribution measured in quasi-differential time-of-flight scattering experiments order isolate elastic and inelastic events. Pulse height distributions from in-beam measurements were used generate response functions, which reconstruct prompt neutron spectra. This validated by reconstructing 252 Cf spontaneous pulse distribution. Monte ...

The pulsatile secretion of hormones is an efficient way of coding a large variety of chemical messages. The GnRH pulse pattern determines which gonadotropin is released when and at what concentration, prescribing a detailed set of instructions to the gonads that produce changes in the steroid hormone milieu. Although GnRH neurons possess some inherent rhythmicity, they are diffusely situated wi...

BACKGROUND Due to its easy applicability, pulse wave has been proposed as a surrogate of electrocardiogram (ECG) for the analysis of heart rate variability (HRV). However, its smoother waveform precludes accurate measurement of pulse-to-pulse interval by fiducial-point algorithms. Here we report a pulse frequency demodulation (PFDM) technique as a method for extracting instantaneous pulse rate ...

A pair of basis functions is presented for the surface integral, method of moment solution of scattering by arbitrarily-shaped, three-dimensional dielectric bodies. Equivalent surface currents are represented by orthogonal unit pulse vectors in conjunction with triangular patch modeling. The electric field integral equation is employed with closed geometries for dielectric bodies; the method ma...

We consider travelling periodic and quasi-periodic wave solutions of a set of coupled nonlinear Schrödinger equations. In fibre optics these equations can be used to model single mode fibers with strong birefingence and two-mode optical fibers. Recently these equations appear as model, which describe pulse-pulse interaction in wavelength-division-multiplexed channels of optical fiber transmissi...

Divergence in mate recognition systems among closely related species is an important contributor to assortative mating and reproductive isolation. Here, we examine divergence in male song traits and female preference functions in three cricket species with songs consisting of long trills. The shape of female preference functions appears to be mostly conserved across species and follows the pred...

in this paper, we consider a new class of analytic functions in the unit disk using polynomials of order alpha. we give some sufficient conditions for functions belonging to this class.
