The assembly of stellar and supermassive black hole (SMBH) mass in elliptical galaxies since $z\sim1$ can help to diagnose the origins locally-observed correlations between SMBH mass. We therefore construct three samples galaxies, one at $z\sim0$ two $0.7\lesssim z \lesssim2.5$, quantify their relative positions $M_{BH}-M_*$ plane. Using a Bayesian analysis framework, we find evidence for trans...

introduction: we have recently reported the presence of two potassium currents with 598 and 368 ps conductance in the rough endoplasmic reticulum (rer) membrane. the 598 ps channel was voltage dependent and atp sensitive. however, the 368 ps channel was rarely observed and its identity remained obscure. since cationic channels in intracellular organelles such as mitochondria and rer play import...

In this paper, we investigate the self-adaptive source separation problem for convolutively mixed signals. The proposed approach uses a recurrent structure adapted by a generic rule involving arbitrary separating functions. We rst analyze the stability of this class of algorithms. We then apply these results to some classical rules for instantaneous and convolutive mixtures that were proposed i...

Abstract This study was aimed at evaluating the effect of freeze-drying and lacto-fermentation on texture parameters images sensory attributes beetroots. The samples were imaged using a flatbed scanner, textures from converted to color channels L, a, b, R, G, B, X, Y, Z computed. discrimination raw processed beetroots performed models based selected for each channel. quality determined related ...

Shannon’s entropy power inequality (EPI), e ) ≥ e + e ) for independent continuous random variables X and Y , with h(X) the differential entropy of X , has found many applications in Gaussian channel coding theorems. Equality holds iff both X and Y are Gaussian. For all the major applications of the EPI, it suffices to restrict Y to be Gaussian. The statement of this restricted EPI is that give...

We use Brownian dynamics (BD) simulations to study the ionic conduction and valence selectivity of a generic electrostatic model of a biological ion channel as functions of the fixed charge Q(f) at its selectivity filter. We are thus able to reconcile the discrete calcium conduction bands recently revealed in our BD simulations, M0 (Q(f)=1e), M1 (3e), M2 (5e), with a set of sodium conduction ba...

This work compares the threshold applied to swirling strength as well vortex orientation statistics in total and fluctuating velocity fields using direct numerical simulations of compressible incompressible turbulent channel flows. It is concluded that difference for identification minimal logarithmic region such these two situations share same threshold. Regarding orientation, inclination angl...

For a nite group G the commutativity degree denote by d(G) and dend:$$d(G) =frac{|{(x; y)|x, yin G,xy = yx}|}{|G|^2}.$$ In [2] authors found commutativity degree for some groups,in this paper we nd commutativity degree for a class of groups that have high nilpontencies.

In this paper, transmission over a wireless channel is interpreted as a two-person zero-sum game, where the transmitter gambles against an unpredictable channel, controlled by nature. Mutual information is used as payoff function. Both discrete and continuous output channels are investigated. We use the fact that mutual information is a convex function of the channel matrix or noise distributio...
