Because of its simplicity, low memory requirement, computational cost, and global convergence properties, the Conjugate Gradient (CG) method is most popular iterative mathematical technique for optimizing both linear nonlinear systems. Some classical CG methods, however, have drawbacks such as poor numerical performance in terms iterations function evaluations. To address these shortcomings, re...

For solving systems of linear algebraic equations with blockfivediagonal matrices arising in geoelectrics and diffusion problems, the parallel matrix square root method, conjugate gradient method with preconditioner, conjugate gradient method with regularization, and parallel matrix sweep algorithm are proposed and some of them are implemented numerically on multi-core CPU Intel. Investigation ...

A prototype of a novel class of DNA alkylating agents, which combines the DNA crosslinking moiety chlorambucil (Chl) with a sequence-selective hairpin pyrrole-imidazole polyamide ImPy-beta-ImPy-gamma-ImPy-beta-Dp (polyamide 1), was evaluated for its ability to damage DNA and induce biological responses. Polyamide 1-Chl conjugate (1-Chl) alkylates and interstrand crosslinks DNA in cell-free syst...

UltraWideband (UWB) systems use Multi-Band OFDM (MB-OFDM) techniques for transmission. UWB based systems are power limited by the regulation of Federal Communications Commission (FCC). CP introduces correlation in the transmitted data sequence and hence introduces ripples in the power spectral density (PSD) of the transmitted data. This in turn reduces the range of data transmission. The overla...

We describe PP-BCG, a parallel iterative solver for the solution of dense and symmetric positive-definite linear systems with multiple right-hand sides suitable for MPPs. Such linear systems appear in the context of stochastic estimation of the diagonal of the matrix inverse in Uncertainty Quantification and the trace of matrix products in statistical analysis. We propose a novel numerical sche...

the efficiency and robustness of reliability methods are two important factors in first order reliability method (form). the conjugate choice control (ccc) and directional chaos control method (dcc) were developed to improve the robustness and efficiency of form formula using the stability transformation method. in this paper, the ccc and dcc methods are applied for reliability analysis of a co...

conclusions the prepared antibody can be used for the development of an elisa kit to assay afm1 in milk and other biological fluids. background aflatoxins are the most extensively studied group of mycotoxins produced by molds, especially the aspergillus group, which are highly toxic to animals and humans. objectives since immunoassay is a simple and rapid method for the analysis of many toxic s...

We describe a new high performance conjugate gradient (HPCG) benchmark. HPCG is composed of computations and data access patterns commonly found in scientific applications. HPCG strives for a better correlation to existing codes from the computational science domain and be representative of their performance. HPCG ismeant to help drive the computer system design and implementation in directions...

In this paper, we consider (n-1, 1)-type conjugate boundary value problem for coupled systems of the nonlinear fractional differential equation

Pneumococcal conjugate vaccines (PCVs) have demonstrated efficacy against childhood pneumococcal disease in several regions globally. We demonstrate how spatial epidemiological analysis of a PCV trial can assist in developing vaccination strategies that target specific geographic subpopulations at greater risk for pneumococcal pneumonia. We conducted a secondary analysis of a randomized, placeb...
