Background: Brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. Serum agglutination test (SAT) is the most-widely used test for diagnosing brucellosis. The enzyme linked immunosorbent assay (ELISA) can also determine specific antibody classes against brucella. It is a sensitive, simple and rapid test, which coul...

We consider the linear or quadratic 0/1 program P : f = min{cx + xFx : Ax = b; x ∈ {0, 1}}, for some vectors c ∈ R, b ∈ Z, some matrix A ∈ Zm×n and some real symmetric matrix F ∈ Rn×n. We show that P can be formulated as a MAX-CUT problem whose quadratic form criterion is explicit from the data of P. In particular, to P one may associate a graph whose connectivity is related to the connectivity...

A biclique is a complete bipartite subgraph of a graph. This paper investigates the fractional biclique cover number, bc∗(G), and the fractional biclique partition number, bp∗(G), of a graph G. It is observed that bc∗(G) and bp∗(G) provide lower bounds on the biclique cover and partition numbers respectively, and conditions for equality are given. It is also shown that bc∗(G) is a better lower ...

in order to have a sustainable agriculture it is necessary to use environmental friendly inputs to improve ecological aspects of environment. basil (ocimum basilicum l.) is a medicinal and vegetable crop which is cultivated in different parts of the world. an experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a complete rand...

In this paper we analyze the optimal joint decisions of when, how and howmuch to replenish customers with products of varying ages. We discuss the main features of the problem arising in the joint replenishment and delivery of perishable products, and we model them under general assumptions. We then solve the problem by means of an exact branch-and-cut algorithm, and we test its performance on ...

Part I of this work answered the following fundamental question: Under and only under what (n, k, d) values does proactively choosing the helper nodes improve the storagebandwidth tradeoff of regenerating codes (RCs)? A critical component of the achievability results in Part I is a lowcomplexity helper selection solution, termed the family helper selection (FHS) scheme. In Part I, FHS was prove...
