traumatic brain injury (tbi) is a common reason of brain tissue loss as a result of tumors, accidents, and surgeries. renewal of the brain parenchyma is restricted by many reasons such as inimical substances produced as the result of trauma and also inflammatory responses. a strong cascade of inflammatory responses begins as a result of tbi which include recalling peripheral leukocytes into the...

The Distributed Particle-Mesh Ewald method (DPME) is a parallel Ewald summation method that is based on the O(NlogN) PME method for evaluating the electrostatic interactions of a periodic particle system, where N is the number of particles in the unit cell. We present three implementations of the DPME method which are evaluated on a network of workstations and the Cray T3D. The performance of t...

In this paper, the feasibility and efficiency of noncausal prediction in a P-frame is examined, and based on the findings, a new P-frame coding scheme is proposed. Motioncompensated inter-frame prediction, which has been used widely in low-bit-rate television coding, is an efficient method to reduce the temporal redundancy in a sequence of video signals. Therefore, the proposed scheme combines ...

The problem of finding p-harmonic flows arises in a wide range of applications including color image (chromaticity) denoising, micromagnetics, liquid crystal theory, and directional diffusion. In this paper, we propose an innovative curvilinear search method for minimizing p-harmonic energies over spheres. Starting from a flow (map) on the unit sphere, our method searches along a curve that lie...

Much effort in the discrete location theory has aimed at developing insights concerning the classical models with one decision maker only. In this paper, we study a competitive model with two noncooperative decision makers: the leader and the follower. They compete to attract clients from the given market and wish to maximize their own profits. In fact, this is the noncooperative Stackelberg ga...

Since the eshablishment of p-aminobenzoic acid as a member of the B vitamin group, a considerable interest has been shown in methods of determination in natural materials. Since known chemical methods are not sufficiently sensitive, it became evident that microbiological tests should be the most practicable. The organism Clostridium acetobutylicum has been used (I) but no general assay procedur...

Capacitated p-median problem (CPMP) is an important variation of facility location problem in which p capacitated medians are economically selected to serve a set of demand vertices so that the total assigned demand to each of the candidate medians must not exceed its capacity. The classical CPMP uses a network in a Euclidean plane such that distance between any two points in the network is the...

Entity resolution is a fundamental task in data integration. Recent studies of this problem, including active learning, crowdsourcing, and pay-as-you-go approaches, have started to involve human users in the loop to carry out interactive entity resolution tasks, namely to invite human users to judge whether two entity descriptions refer to the same real-world entity. This process of judgment re...

We consider the Newton iteration for computing the principal matrix pth root, which is rarely used in the application for the bad convergence and the poor stability. We analyze the convergence conditions. In particular it is proved that the method converges for any matrix A having eigenvalues with modulus less than 1 and with positive real part. Based on these results we provide a general algor...
