DYLP is a full implementation of the dynamic simplex algorithm for linear programming. Dynamic simplex attempts to maintain a reduced active constraint system by regularly purging loose constraints and variables with unfavourable reduced costs, and adding violated constraints and variables with favourable reduced costs. In abstract, the code alternates between primal and dual simplex algorithms...

In order to improve the specificity and sensitivity of the techniques for the human anisakidosis diagnosis, a method of affinity chromatography for the purification of species-specific antigens from Anisakis simplex third-stage larvae (L3) has been developed. New Zealand rabbits were immunized with A. simplex or Ascaris suum antigens or inoculated with Toxocara canis embryonated eggs. The IgG s...

In topology, a basic building block for spaces is the n-simplex. A 0-simplex is a point, a 1-simplex is a closed interval, a 2-simplex is a triangle, and a 3-simplex is a tetrahedron. In general, an n-simplex is the convex hull of n + 1 vertices in n-dimensional space. One constructs more complicated spaces by gluing together several simplices along their faces, and a space constructed in this ...

A 16yearold girl visited our clinic because of chest pain that was exacerbated with swallowing. Ten days previously, the patient had spilled boiling water on herself and burned her legs. She saw a dermatologist, who prescribed doxycycline (100 mg per day in tablet form) to prevent skin infection. Five days previously, the patient took a doxycycline tablet with a small amount of water just befor...

OBJECTIVE To evaluate the effect of treatment with the antiherpes drug valacyclovir on MRI-evident lesions in patients with relapsing-remitting MS in a phase 2, randomized, double-blind, placebo-controlled study. BACKGROUND It has been postulated from virologic studies that herpesvirus infection could play a role in the progression of MS. METHODS Patients were eligible for the study if they...

Bernstein estimators are well-known to avoid the boundary bias problem of traditional kernel estimators. The theoretical properties these have been studied extensively on compact intervals and hypercubes, but never simplex, except for mean squared error density estimator in Tenbusch (1994) when $d = 2$. simplex is an important case as it natural domain compositional data. In this paper, we make...

A simplex-centroid design for q mixture components comprises of all possible subsets of the q components, present in equal proportions. The design does not contain full mixture blends except the overall centroid. In real-life situations, all mixture blends comprise of at least a minimum proportion of each component. Here, we introduce simplex-centroid designs which contain complete blend...

BACKGROUND Traditional diagnostic tests such as skin prick tests (SPT) and specific IgE (slgE) against whole Anisakis simplex extract have low specificity. Consequently, allergy to A simplex is overdiagnosed. OBJECTIVE Our aim was to compare tests used in component-resolved diagnosis. METHODS We evaluated 34 patients with allergy to A simplex, 15 patients with acute urticaria who were sensi...
