A discussion of the functional setting customarily adopted in General Relativity (GR) is proposed.This is based on the introduction of the notion of nonlocal point transformations (NLPTs).While allowing the extension of the traditional concept of GR-reference frame, NLPTs are important because they permit the explicit determination of the map betwe

Gadolinium is a frequently used contrast Brain Teaser Puzzles product for MRI exam.It is well known to be less immuno-reactive than iodine used in tomodensitometry but is safety is not completely exempt of secondary effect.Here we report one case of acute interstitial pulmonary toxicity due to gadolinium.After quick elimination of others paper good

Introduction: Meningiomas are slow growing primary central nervous system (CNS) tumours attached to the duramater, which arise from the meningothelial cells of the arachnoid.Grading of meningioma based on histological findings assisted with supplementary immunohistochemical studies, predicts the prognosis of meningioma with good precision.Aim: To e

Abstract For analog signals comprised of several, possibly overlapping, finite duration pulses with unknown shapes and paper goods - entertainment time positions, an efficient sub-Nyquist sampling systems is based on Gabor frames.To improve the realizability of this sampling system, we present alternative method for the case that Gabor windows are
