The Saccharomyces cerevisiae genome contains five families of long terminal repeat (LTR) retrotransposons, Ty1-Ty5. The sequencing of the S. cerevisiae genome provides an unprecedented opportunity to examine the patterns of molecular variation existing among the entire genomic complement of Ty retrotransposons. We report the results of an analysis of the nucleotide and amino acid sequence varia...

In the preceding paper (1) some chemical, antigenic, and biological propert ies of a series of ace toace ty la ted derivat ives of Salmonella adelaide flagellin were described. Several chemical and antigenic tests revealed tha t as flagellin was ace toace ty la ted to increasing extents there was a s teady decline in the affinity of the molecule for anti-flagellin antibodies. This loss in antig...

By a solution of (.) wemean a function y(t) ∈ C[ty,∞) which has the property r(t)y′(t) ∈ C[ty,∞) and r(t)(r(t)y′(t))′ ∈ C[ty,∞) and satisfies (.) on [ty,∞) for every t ≥ ty ≥ t. We restrict our attention to those solutions of (.) which exist on I and satisfy the condition sup{|x(t)| : t ≥ t} >  for any t ≥ ty. We assume that (.) possesses such a solution. A solution y(t) of (...

This paper presents a TEX-based way to localize LATEX documents for natural languages with a script based on the Arabic alphabet. So, native speakers of such natural languages who do not know English can use and understand LATEX.

Combining these three definitions, Zamfirescu [12] proved the following important result. Theorem 1.1. Let (X ,d) be a complete metric space and T : X → X a mapping for which there exists the real numbers a,b, and c satisfying a∈ (0,1), b,c ∈ (0,1/2) such that for each pair x, y ∈ X , at least one of the following conditions holds: (z1) d(Tx,Ty)≤ ad(x, y), (z2) d(Tx,Ty)≤ b[d(x,Tx) +d(y,Ty)], (z...
