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.

The Guillain-Barré syndrome is often preceded by a herpes virus infection. Herpes simplex virus, however, has rarely been observed as the causative agent. A patient is described with a herpes simplex virus infection followed by a Guillain-Barré syndrome. Immunoblotting was used to detect herpes simplex virus-specific antibodies in serum and cerebrospinal fluid.

Bacillus simplex DSM 1321 is a Gram-positive, spore-forming, and aerobic bacterium. Here, we report the draft genome sequence of B. simplex DSM 1321, with 6,494,937 bp, which will provide useful information for setting up phylogenomics in genomic taxonomy of the Bacillus-like bacteria as well as for the functional gene mining and application of B. simplex DSM 1321.

This paper shows that the optimal simplex, in the sense of minimizing the linear interpolation error of the quadratic function u(x) = x2 measured in Lp-norm, is the equilateral simplex. It also contains several explicit formulae on the best interpolation error when the volume of the simplex is one.

We describe a case of chronic atypical herpes simplex type 2 encephalitis in an immunocompromised 68 year old man presenting with headache and cognitive changes without focal neurological or MRI findings. To our knowledge this is the first described case of herpes simplex encephalitis associated with normal MRI brain imaging and non-focal neurological examination. This further expands the range...

Euastacus morgani sp. n., is described from a highland, rainforest site in Bindarri National Park, in eastern New South Wales, Australia. Euastacus morgani is found living sympatrically with two more common species, Euastacus dangadi Morgan, 1997 and Euastacus neohirsutus Riek, 1956. Systematically, the species belongs in the 'simplex' complex of the genus that includes Euastacus simplex Riek, ...
