The hepatic sinusoids are lined by a unique population of hepatic sinusoidal endothelial cells (HSEC), which is one of the first hepatic cell populations to come into contact with blood components. However, HSEC are not simply barrier cells that restrict the access of bloodborne compounds to the parenchyma. They are functionally specialised endothelial cells that have complex roles, including n...

The novel current-tunable voltage-mode universal biquad filter and sinusoidal quadrature oscillator using only two current-controlled current differencing buffered amplifiers (CCCDBAs) and two capacitors without external passive resistors have been presented. The first proposed filter realizes all the five standard types of the biquadratic functions and provides independent electronic tuning of...

Numerical simulation of MHD free convection in a two-dimensional trapezoidal cavity hybrid nanofluid has been carried out this research. The is heated sinusoidal from the bottom wall, and inclined walls are cooled while top wall isolated. (MgO-Ag/water) used as working fluid. numerical validated with past papers met good agreement. considered parameters range Rayleigh number (Ra= 103 to 106), H...

We consider a model for vehicle motion coordination for three vehicles that uses coupled oscillator steering control. Prior work on such models has focused primarily on sinusoidal coupling functions, which typically give behavior in which individual vehicles move either in straight lines or in circles. We show that other, more exotic trajectories are possible when more general coupling function...

Substantial recent experimental evidence has demonstrated the existence of reciprocal interactions between the microvascular bed of a specific organ and intravascular metastatic tumor cells through expression of adhesion molecules and nitric oxide release, resulting in a significant impact upon metastatic outcomes. This review summarizes the current findings of adhesive and cytotoxic endothelia...

We report psychophysical measurements of spatial pooling functions for contrast gain control. We use a nulling technique to measure the dependence of contrast induction on the spatial frequency of a sinusoidal contrast modulation. This dependence on spatial frequency, when transformed, provides the profile of a spatial pooling function. The measured profiles are fitted well by Gaussians. We con...

The trigonometric network, introduced in this paper, is a multilayer feedforward neural network with sinusoidal activation functions. Unlike the N-dimensional Fourier series, the basis functions of the proposed trigonometric network have no strict harmonic relationship. An effective training algorithm for the network is developed. It is shown that the trigonometric network performs better than ...

Ghost cancellation algorithms for restoring magnetic resonance imaging (MRI) images in medical applications are described. The approach is to model the effect of the time delays and the asymmetry of the sinusoidal readout gradient for even and odd lines with two phase functions relating the actual object density to even and odd parts of the observed image. A priori information about the phase f...

Wireless power transmission is based on electromagnetical phenomenon between two separate coils. In order to transfer power from one to the other, we have to cause a time-varying current along one coil. Many of conventional wireless power transmission systems suppose a sinusoidal current of the coil. One reason for it could be the convenience that we have a sinusoidal power source as the indust...

The paper introduces and describes the spectrum-based design of RBF neural networks. The RBF neural networks used in the paper work with damped sinusoidal nonlinear activation functions. The concept of the associated spectrum of the data is introduced and it is shown how to apply this spectrum to find the number and internal parameters of hidden neurons for a neural network solution of the rela...
