Background and Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of nosocomial and community acquired infections. Detection of MRSA in laboratories is very important for treatment and appropriate infection control. The aim of this study was to evaluate cefoxitin disk diffusi...

We provide a general method to analyze the asymptotic properties of a variety of estimators of continuous time diffusion processes when the data are not only discretely sampled in time but the time separating successive observations may possibly be random. We introduce a new operator, the generalized infinitesimal generator, to obtain Taylor expansions of the asymptotic moments of the estimator...

introduction: in this study, using the phenotypic and genotypic methods, oxacillin susceptibility in staphylococcus aureus (s. aureus) strains isolated from patients at two government hospitals in ilam, iran was tested. materials and methods: out of 200 s. aureus isolates from different human clinical specimens consisting of blood (31%), wound (20%), urine (21%), catheters (7%), sputum (12%), o...

Last time, we talked about electrical networks, and we saw that we could reproduce some of the things we have been doing with spectral methods with more physically intuitive techniques. These methods are of interest since they are typically more robust than using eigenvectors and they often lead to simpler proofs. Today, we will go into more detail about a similar idea, namely whether we can in...

background: methicillin resistant staphylococcus aureus (mrsa) has been emerged as a nosocomial and community acquired pathogen worldwide. there are many challenges for laboratory detection of mrsa. the aim of this study was to compare different phenotypic methods with pcr based method as a gold standard for detection of meca gene. methods: a total of 220 clinical isolates of s. aureus which we...

As a counterpoint to classical stochastic particle methods for diffusion, we develop a deterministic particle method for linear and nonlinear diffusion. At first glance, deterministic particle methods are incompatible with diffusive partial differential equations since initial data given by sums of Dirac masses would be smoothed instantaneously: particles do not remain particles. Inspired by cl...

In this paper, we present a high order implicit scheme for one dimension heat conduction equations. The scheme is proved to be unconditionally stable. Based on the scheme a class of parallel alternating group explicit iterative method (AGEI) is constructed, and convergence analysis for the method is done. Numerical experiments show that the method is effective in computation.
