introduction: purkinje cell (pc) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. here, the spectral analysis of pcs firing in control, 3-acety...

Abstract   The present paper is devoted to implementation of the immersed boundary technique into the Fourier pseudo-spectral solution of the vorticity-velocity formulation of the two-dimensional incompressible Navier-Stokes equations. The immersed boundary conditions are implemented via direct modification of the convection and diffusion terms, and therefore, in contrast to some other similar ...

We present the large-eddy simulation of the lid-driven cubic cavity flow by the spectral element method (SEM) using three subgrid-scale models. Two spectral filtering techniques suitable for these simulations have been implemented. Numerical results for Reynolds number Re = 12.000 are showing very good agreement with the Direct Numerical Simulation (DNS) results and relatively good agreement wi...

Line-by-line calculations are becoming the standard procedure for carrying spectral simulations. However, it is important to insure the accuracy of such spectral simulations through the choice of adapted models for the simulation of key parameters such as line position, intensity, and shape. Moreover, it is necessary to rely on accurate spectral data to guaranty the accuracy of the simulated sp...

This paper discusses recent advances in the full spectral simulation of scenes with partial cloud cover. We examine the effect of broken cloud fields on the solar illumination reaching the ground. Application of aerosol retrieval techniques in the vicinity of broken clouds leads to significant over-prediction of aerosol optical depth because of the enhancement of visible illumination due to sca...

* Corresponding author. ** This work was sponsored by CAPES and SELPER (Brazil). Abstract – The simulation of one or more bands of a multispectral sensor by combination of other bands is a useful tool as an image processing technique. This work presents a simulation technique for the ETM+ panchromatic band based on linear combination of ETM+ multispectral bands. The simulation method takes into...

Theory, numerical simulation, and experiment on the interaction of electromagnetic wave with suddenly created periodic plasma layers are presented. In the experiment, frequency-downshifted signals of considerably large spectral width and enhanced spectral intensity were detected. Numerical simulation of the experiment, that the plasma has a finite periodic structure and is created much faster t...

We study the effect of imperfect subtraction of the Sunyaev-Zel’dovich effect (SZE) using a robust and non-parametric method to estimate the SZE residual in the Planck channels. We include relativistic corrections to the SZE, and present a simple fitting formula for the SZE temperature dependence for the Planck channels. We show how the relativistic corrections constitute a serious problem for ...

The AFSSI-C is a spectral imager that generates spectral classification directly, in fewer measurements than are required by traditional systems that measure the spectral datacube (which is later interpreted to make material classification). By utilizing adaptive features to constantly update conditional probabilities for the different hypotheses, the AFSSI-C avoids the overhead of directly mea...
