DEFINITION 0.1. Let Fx, F2, F be subsets of a boolean algebra B. Then the (F1, F2, F)-Separation Principle, written Sep(F~, F2, F) for short, is the following: whenever aEF1, bEF2 and a ^ b = O , there is c~F with a<.c and cAb=O. The (F1, F2, F)-Interpolation Principle, written Int(Ft , F2, F) for short, is the following: whenever a~F1, b~F2 and a<.b there is ceF such that a<~c<~b. Clearly Int ...

During a follicular wave in mares, the two largest follicles (F1 and F2) begin to deviate in diameter when F1 is a mean of 22.5 mm. The intrafollicular effects of pregnancy-associated plasma protein-A (PAPP-A), IGF-I, activin-A and vascular endothelial growth factor (VEGF) on other follicular-fluid factors during deviation were studied. In four treated groups (n = 7/group), a single dose of one...

Unlike previous pandemic viruses, the 2009 H1N1 pandemic influenza virus does not code for the virulence factor PB1-F2. The genome of the 2009 H1N1 virus contains three stop codons preventing PB1-F2 expression; however, PB1-F2 production could occur following genetic mutation or reassortment. Thus, it is of great interest to understand the impact that expression of the PB1-F2 protein might have...

BACKGROUND The malaria parasite Plasmodium falciparum EBA-175 binds its receptor sialic acids on glycophorin A when invading erythrocytes. The receptor-binding region (RII) contains two cysteine-rich domains with similar cysteine motifs (F1 and F2). Functional relationships between F1 and F2 domains and characterization of EBA-175 were studied using specific monoclonal antibodies (mAbs) against...

We construct a class of three-Lee-weight and two infinite families of five-Lee-weight codes over the ring R = F2 + vF2 + v 2 F2 + v 3 F2 + v 4 F2, where v 5 = 1. The same ring occurs in the quintic construction of binary quasi-cyclic codes. They have the algebraic structure of abelian codes. Their Lee weight distribution is computed by using character sums. Given a linear Gray map, we obtain th...

Let F be an n-uniform hypergraph on 2n vertices. Suppose that |F1∩F2∩F3∩F4| ≥ 2 and |F1∪F2∪F3∪ F4| ≤ n−2 holds for all F1,F2,F3,F4 ∈F . We prove that the size of F is at most (2n−4 n−2 ) for n sufficiently large.

Let F be an n-uniform hypergraph on 2n vertices. Suppose that |F1 ∩ F2 ∩ F3| ≥ 1 and |F1 ∪ F2 ∪ F3| ≤ 2n− 1 holds for all F1, F2, F3 ∈ F . We prove that the size of F is at most ( 2n−2 n−1 ) .
