This paper presents a new stochastic model for two dimensional layouts of large size. Two problems are addressed: (i) Under the condition that the number of wires emanating from a block is Poisson distributed, determine the distribution of channel width, thus estimating the average channel width. (ii) Given T tracks for each channel, determine the success(More)
Central limit theorems are obtained for the \perturbation analysis Robbins-Monro single run" (PARMSR) optimization algorithm, with updates either after every L customers or after every busy period, in the context of the optimization of a GI=GI=1 queue. The PARMSR algorithm is a stochastic approximation (SA) method for the optimization of innnite-horizon(More)
OBJECTIVE To explore the changes in the concentrations of neural markers immediately or several months after mild traumatic brain injury (mTBI). METHODS The metabolic markers of neurons in white matter tissues above the lateral ventricle were semi-quantitatively determined by employing 1H magnetic resonance spectroscopic technique (1-H-MRS) in 30(More)
OBJECTIVE Late gadolinium enhancement (LGE) patterns of cardiovascular magnetic resonance (CMR) relying on PSIR (phase-sensitive inversion recovery sequence) techniques had been used to determine the characteristics of LGE in apical hypertrophic cardiomyopathy (ApHCM). METHODS Forty patients pure ApHCM [age, (60.2±10.4) years, 31 men] were enrolled. LGE(More)
