We examine curious behaviors of the Independent Component Analysis (ICA) and Sparse Component Analysis (SCA) when they are applied to some simple stochastic processes called the “simple” and “generalized” spike processes. Both processes put a single spike at a random location in the zero vector of length for each realization. The simple spike process puts a unit impulse whereas the generalized ...

to study yield and its relationships with yield components in 10 varieties of foxtail millet (kfm1 to kfm10), an experiment was carried out in safiabad agricultural research center in rcbd design with three replications for a period of three years (2003 to 2005). vegetative and reproductive characteristics of each cultivar were recordered during the growing seasons. three year results showed si...

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...

An experiment was conducted at the Floriculture Research Field of Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during April, 2015 to February, 2017 to find out the suitable planting materials for specific tuberose genotype for growth, flowering and bulb production of tuberose. Individually both genotypes showed better performances for some ...

The oppossum sphincter of Oddi (SO) exhibits peristaltic spike bursts with accompanying contraction waves that originate proximally in the sphincter of Oddi and propagate toward the duodenum. In this study we recorded myoelectrical activity of the opossum SO and upper gastrointestinal tract in six conscious animals using chronically implanted electrodes. Biopolar electrodes were implanted in th...

OBJECTIVE The aim of this study was to analyze whether cells with long action potential duration, fast Vmax, and spike-and-dome configuration (M-cells) are present in porcine left ventricular myocardium. METHODS Transmembrane action potentials (n = 505) of the left ventricle were recorded with conventional glass microelectrodes in an epicardial-endocardial direction at 2000 ms basic cycle len...

Experimental results suggest that the time structure of neuronal spike trains can be relevant in neuronal signal processing. In view of these results, a shift of interest from analog neural networks to spikeprocessing neural networks has been observed. For tasks like image processing the simulation of these networks has to be performed with the speed of biological neural networks. We investigat...

An experiment was conducted to determine the influence of concentration and mode of application of different growth regulators on growth and yield of Dendrobium hybrid “Thongchai Gold” in subtropical cool climate zone. Various concentrations of GA 3 and BA were applied as foliar spray and drenching mode. GA 100 ppm in combination with BA 100 ppm followed by GA 200 ppm 3 3 increased the plant he...
