background: herpes simplex virus (hsv) is a member of herpesviridae and a leading cause of human viral diseases. meningitis occurs as a complication of hsv-1 or hsv-2 primary infection. objectives: we aimed to evaluate hsv meningitis in children in gorgan province, iran. patients and methods: forty-five cerebrospinal fluid samples were taken from children referred with meningitis symptoms. samp...

background patients with beta thalassemia suffer from increased susceptibility to infections and putridity plays a major role in the patient's morbidity and mortality. the risk of transfusion-transmitted viral infection is well known in these patients. however, there is dearth of information about the seroprevalence of herpes simplex virus (hsv) infection in patients with beta thalassemia in li...

it is well known that in operations research‎, ‎degeneracy can cause a cycle in a network‎ ‎simplex algorithm which can be prevented by maintaining strong‎ ‎feasible bases in each pivot‎. ‎also‎, ‎in a network consists of n arcs‎ ‎and m nodes‎, ‎not considering any new conditions on the entering‎ ‎variable‎, ‎the upper bound of consecutive degenerate pivots is equal‎ $left( ‎begin{array}{c}‎ ‎n...

A discrete statistical model is a subset of probability simplex. Its maximum likelihood estimator (MLE) retraction from that simplex onto the model. We characterize all models for which this rational function. This contribution via real algebraic geometry rests on results Horn uniformization due to Huh and Kapranov. present an algorithm constructing with MLE, we demonstrate it range instances. ...

Abstract This article focuses on solving the fuzzy transportation problem using dual approach of simplex. method uses a strong ranking technique for iterative values trapezoidal numbers within problem. Because approach, (in which cost, demand, and supply appear as numbers) is transformed into crisp valued LPP (Linear Programming Problem) employed simplex procedure solving. The earlier task obta...

An algorithm for solving linear programming problems whose matrix of coefficients contains a large number of "zero" entries is studied. This algorithm is more useful when it is generated as a sub-program in a real-time program. The singly linked lists for storing only the non-zero entries of the coefficients matrix is used. The modified Revised Simplex Method is also used for solving such probl...

acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. acyclovir triphosphate inhibits viral dna-polymerase terminating the chain and...

This paper studies the polynomial basis that generates smallest n-simplex enclosing a given nth-degree curve in Rn. Although Bernstein and B-Spline bases provide feasible solutions to this problem, simplexes obtained by these are not possible, which leads overly conservative results many CAD (computer-aided design) applications. We first prove solves problem (MINVO basis) also for with largest ...

Based on the syllogism of formal logic and triangulation theory of algebraic topology, a new method of knowledge representation with 2-simplex called simplex representation is given in this paper. To show differences, the method is compared with others. The simplex representation has special characteristics in representation abilities, expression ability, and representation modality. General Te...

In this paper, we study the primal and dual simplex algorithms for the maximum flow problem. We show that aVny primal simplex algorithm for the maximum flow problem can be converted into a dual simplex algorithm that performs the same number of pivots and runs in the same time. The converse result is also true though in a somewhat weaker form.
