background leptin, a protein released from adipose tissue, could have significant role in pathogenesis of obesity and type 2 diabetes mellitus. conclusions it is speculated that lower serum leptin levels in diabetic patients may be a consequence of male gender. moreover, results suggest that serum leptin level in women is influenced differently than that in men. results the serum leptin level i...

In this paper, using the boundary properties of the analytic functions we investigate the structure of the discrete spectrum of the boundary value problem iy 1 + q1(x)y2 − λy1 = φ1(x) (0.1) −iy 2 + q2(x)y1 − λy2 = φ2(x), x ∈ R+ and the condition (a1λ+ b1)y2(0, λ)− (a2λ+ b2)y1(0, λ) = 0 (0.2) where q1, q2, φ1, φ2 are complex valued functions, ak 6= 0, bk 6= 0 , k = 1, 2 are complex constants and...

Conjugative transfer of R plasmids R64 and R64drd-11 has been compared in vitro and in vivo without selective pressure by antibiotics in a simplified experimental system; the ecosystem was the bowel of germfree chickens, with the host bacteria almost isogenic, and the plasmids differing only in their conjugative transfer frequency. The spread of repressed and derepressed (drd) R plasmids in rec...

We introduce a novel resource analysis for typed term rewrite systems based on a potential-based type system. This type system gives rise to polynomial bounds on the innermost runtime complexity. We relate the thus obtained amortised resource analysis to polynomial interpretations and obtain the perhaps surprising result that whenever a rewrite system R can be well-typed, then there exists a po...

x x · P(X = x) , where the summation is over the range of X. Here, P(X = x) = P({ω ∈ Ω : X(ω) = x}). The notation above implicitly assumes that range of X is a discrete set that we can enumerate. But we’ll often encounter a continuous random variable X whose range is a continuous space, like the real line R or some subset thereof. In the cases we’ll consider, the random variable X will have a p...

J. Widmann Dear Customer UserCom is becoming more and more popular. In the last edition, we made a number of improvements to the layout and have now decided to print a Spanish version in addition to the English, German and French editions. On the last page, we would like to introduce the METTLER TOLEDO editorial team. The name of the author is now noted along with the title of each article. Inf...
