In this paper we study a parallel form of the SOR method for the numerical solution of the Convection Diffusion equation suitable for GPUs using CUDA. To exploit the parallelism offered by GPUs we consider the fine grain parallelism model. This is achieved by considering the local relaxation version of SOR. More specifically, we use SOR with red black ordering with two sets of parameters ωi j a...

A straightforward synthetic approach was adopted for the construction of a lysosome-targeted drug delivery system (TDDS) using sorbitol scaffold (Sor) linked to octa-guanidine and tetrapeptide GLPG, a peptide substrate of lysosomal cysteine protease, cathepsin B. The main objective was to efficiently deliver the potential anticancer drug, doxorubicin to the target sites, thereby minimizing dose...

BACKGROUND Apoptosis and matrix metalloproteinase (MMP-9) are capable of hydrolysing components of the extracellular matrix and weakening the fetal membranes which leads to eventual rupture, a key process of human parturition. The aim of this study was to determine the effect of supracervical apposition and spontaneous labour on apoptosis and MMP-9 in human fetal membranes at term. METHODS Fe...

CONTEXT Benefits of breastfeeding include lower risk of postneonatal mortality. However, it is unclear whether breastfeeding specifically lowers sudden infant death syndrome (SIDS) risk, because study results have been conflicting. OBJECTIVE To perform a meta-analysis to measure the association between breastfeeding and SIDS. METHODS We identified 288 studies with data on breastfeeding and ...

A coupled pair of harmonic equations is solved by the application of Chebyshev acceleration to the Jacobi, Gauss-Seidel, and related iterative methods, where the Jacobi iteration matrix has purely imaginary (or zero) eigenvalues. Comparison is made with a block SOR method used to solve the same problem. Introduction. In [4], we proposed a general block SOR method for solving the biharmonic equa...

We investigate the performance of several preconditioned Conjugate-Gradient-like algorithms and a standard stationary iterative method (block-line-SOR) on linear systems of equations as they arise from a nonlinear elliptic ame sheet problem simulation. The nonlinearity forces a pseudo-transient continuation process that makes the problem parabolic and thus compacts the spectrum of the Jacobian ...

OBJECTIVE AND METHODS This study established a simple stereological method to obtain quantitative information about two- or three-dimensional structures based on observations from kidney sections in the unilateral ureteral obstruction(UUO) model. RESULTS Tubulointerstitial area(TA) and TA/the area of a rectangular field(RA) were raised gradually, but significantly, in the obstructed kidney fr...

Route falsification attacks are easy to launch in wireless ad hoc networks with on demand routing protocols that employ network-wide flooding of control packets for route discoveries. Colluding insider malicious nodes with no special hardware capability can use packet encapsulation and tunnelling to create bogus short-cuts in routing paths and influence data traffic to flow through them. The cu...

z Evidence summary Flexor tenosynovitis and de Quervain’s tenosynovitis are the 2 most common types of tenosynovitis of the hand. While the term “tenosynovitis” implies an inflammatory condition, pathoanatomically it is better described as a friction overuse injury, resulting in fibrosis Yes. steroid injections are an effective first-line therapy for flexor tenosynovitis of the hand, with a num...

In this work we consider the Successive Overrelaxation (SOR) method for the solution of a linear system Ax = b, when the matrix A has a block p X P partitioned p-cyclic form and its associated block Jacobi matrix Jp 1s weaJdy cyclic of index p. Following the pioneering work by Young and Varga in the 50s many researchers have considered various cases for the spectrum 0'(Jp ) and have determlned ...
