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...

N etworks are one of the most significant developments in computing and a hallmark of modern society. However, along with increasing efficiency and productivity, both at home and in the workplace, networks have costs. One cost is the additional energy that electronic devices consume when attached to networks. Recent studies indicate that the economic and environmental impact of such energy use ...

The world's growing economy and demographic advancement are driving an increase in global energy demand. As worries about carbon emissions grow the demand for electrical production continues to rise, it is necessary develop new methods of electricity production. Fuel cell system one promising factors addressing this problem due its low emissions, easy accessibility, fuel flexibility. In paper, ...

This paper shows the topology of the hybrid grid-connected power system and the performances of the front-end three-phase power inverter. The renewable sources of the hybrid power system consist of a solid oxide fuel cell and a wind-turbine. This type of combination is the most efficient one. The proposed topology benefits of the one common DC-AC inverter which injects the generated power into ...
