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...

We consider the existence of at least one positive solution to the dynamic boundary value problem −y (t) = λf(t, y(t)), t ∈ [0, T ]Ty(0) = ∫

For x ∈ Z let Tx denote the triangular number x(x + 1)/2. Following the recent approach of Z. W. Sun, we show that every natural number can be written in any of the following forms with x, y, z ∈ Z: x + Ty + Tz , x 2 + 2Ty + Tz , x 2 + 3Ty + Tz , x + 5Ty + 2Tz , x 2 + 6Ty + Tz , 3x 2 + 2Ty + Tz , x + 3y + Tz , 2Tx + Ty + Tz , 3Tx + 2Ty + Tz , 5Tx + Ty + Tz . This confirms some conjectures raise...

For nonnegative random variables X and Y we write X ≤ttt Y if TX(p) ≤ TY (p) for all p ∈ (0, 1), where TX(p) ≡ ∫ F−1(p) 0 (1− F (x)) dx and TY (p) ≡ ∫ G−1(p) 0 (1−G(x)) dx; here F and G denote the distribution functions of X and Y , respectively. The purpose of this article is to study some properties of this new stochastic order. New properties of the excess wealth (or right spread) order, and...

Suppose that A is a C^*-algebra. We consider the class of A-linear mappins between two inner product A-modules such that for each two orthogonal vectors in the domain space their values are orthogonal in the target space. In this paper, we intend to determine A-linear mappings that preserve orthogonality. For this purpose, suppose that E and F are two inner product A-modules and A+ is the set o...
