Neuroleptic malignant syndrome (NMS) is a rare, life-threatening but potentially treatable condition. This study was performed to investigate the clinical spectrum, antecedent events and outcome of NMS patients admitted in the Neurology department of a large teaching hospital of North India. Fourteen cases of NMS were taken after a thorough search during a(More)
The organization in brain networks shows highly modular features with weak inter-modular interaction. The topology of the networks involves emergence of modules and sub-modules at different levels of constitution governed by fractal laws that are signatures of self-organization in complex networks. The modular organization, in terms of modular mass,(More)
In the present work, a facile approach to construct a nonvolatile resistive random access memory device based on the heterojunction of silver nanoparticles and aluminum oxide is reported. The device structure consisting of Aluminum-Aluminum oxide-Silver Nanoparticles-Aluminum is used to study the charge transport. The current-voltage measurements of this(More)
Performance tuning in database management system means enhancing the performance of database, i.e. minimizing the response time at a very optimum cost. Query optimization is one of the important aspects of performance tuning. Lots of research work has been done in this field but it is still ongoing process. To achieve high performance at a very low cost(More)
We examine the possibilities of various coupling mechanisms among a group of identical stochastic oscillators via Chemical Langevin formalism where each oscillator is modeled by stochastic model of testosterone (T) releasing pathway. Our results show that the rate of synchrony among the coupled oscillators depends on various parameters namely fluctuating(More)
We examine the synchrony in the dynamics of localized [Ca(2 + )](i) oscillations among a group of cells exhibiting such complex Ca(2 + ) oscillations, connected in the form of long chain, via diffusing coupling where cytosolic Ca(2 + ) and inositol 1,4,5-triphosphate are coupling molecules. Based on our numerical results, we could able to identify three(More)
The temporal behavior of segmentation clock oscillations shows phase synchrony via mean field like coupling of delta protein restricting to nearest neighbors only, in a configuration of cells arranged in a regular three dimensional array. We found the increase of amplitudes of oscillating dynamical variables of the cells as the activation rate of(More)
We examine the synchrony of the dynamics of localized [Ca 2+ ]i oscillations in internal pool of astrocytes via diffusing coupling of a network of such cells in a certain topology where cytosolic Ca 2+ and inositol 1,4,5-triphosphate (IP3) are coupling molecules; and possible long range interaction among the cells. Our numerical results claim that the cells(More)
