Infection of ruminants with Mycobacterium avium subspecies paratuberculosis (M. paratuberculosis) leads to a chronic and often fatal granulomatous enteritis known as Johne's disease. Most infections with M. paratuberculosis occur during the first 6 months of life, and there is some evidence for transmission in utero. Once established, infections typically exist in a subclinical state for severa...

avian influenza virus (aiv) infection is a major cause of bird or human mortality and morbidity, therefore the rapid identification of the virus is of important clinical and epidemiological implication. methods: a multiplex reverse transcriptase pcr (rt-pcr) was optimized for the detection of influenza a virus and the h5 and h9 subtypes. the influenza type a specific primers were directed to th...

A logic network to produce the sequency ordered Hadamard matrix H based on the property of gray code and orthogonal group codes is developed. The network uses a counter to generate Rademacher function such that the output of H will be in sequency. A general purpose shift register with output logic is used to establish a sequence of period P corresponding to a given value of order m of the Hadam...

using the nanotechnology and decreasing the dimension of reinforcement particles to nanometer, outstanding mechanical properties are achieved in aluminum matrix nanocomposites. fabrication of aluminum matrix nanocomposites by casting is of great importance because of its simplicity, low cost and ease of the control of matrix microstructure. in this study, the aging behavior of nanocomposite sam...

GOAL: The NTW package allows the computation of the interaction network of n genes (A, nxn) based on m independent experiments collecting gene expression profiles (X, nxm) with or without the associated transcriptional pertubation matrix (P, nxm, contains the direct targets of each of the m perturbation done on the system). The approach is based on ordinary differential equations (ODE) and 3 op...

the aim of this study was to investigate the frequency, location and type of rpob gene mutations in mycobacterium tuberculosis (mtb) collected from patients in the southern endemic region of iran. drug susceptibility testing was determined by using the bactec system and the center for diseases control’s (cdc) standard conventional proportional method. in 29 rifampicin-resistant mtb (85%) isolat...

In this paper we study the potential of simple linear gene-protein interaction networks to store sparse input-output patterns. This problem bears similarity to the engineering task of reconstructing gene networks from time series of expression data, such as sets of microarrays. This is currently an intensively studied field where some results are directly applicable to our context. The central ...

First published July 30, 2014; doi:10.1152/ajpcell.00086.2014.—Hepatic stellate cells (HSCs) generate matrix, which in turn may also regulate HSCs function during liver fibrosis. We hypothesized th...

In this paper, a numerical method for nding minimal solution of a mn fullyfuzzy linear system of the form Ax = b based on pseudo inverse calculation,is given when the central matrix of coecients is row full rank or column fullrank, and where A~ is a non-negative fuzzy mn matrix, the unknown vectorx is a vector consisting of n non-negative fuzzy numbers and the constant b isa vector consisting o...
