Central MessageA Canadian study finds that open repair of TAAA has significantly greater short-term mortality and morbidity compared with an endovascular approach, but long-term survival is comparable. However, patient management must be individually tailored to achieve optimal outcomes.See Article page 516. A outcomes. See Open thoracoabdominal aortic aneurysm (TAAA) among the most technically...

In 1971, Omran formulated the theory of epidemiological transition to explain the shift in mortality and disease patterns worldwide. The theory begins with the major premise that mortality is a fundamental factor in population dynamics. At the beginning of time was the age of so-called pestilence and famine. Mortality was high; life expectancy around 20–30 years; and famine, injuries, and infec...

Harmony Search (HS) is a new meta-heuristic algorithm imitating the music improvisation process where musicians search for a better state of harmony. In this paper, a new improvisation scheme is proposed that explicitly uses a probabilistic model of candidate solutions stored in the harmony memory. Pitch adjustment uses a probability distribution to mutate a decision variable while random selec...

1. Omran Ahmadi (Institute for Research in Fundamental Sciences (IPM), Iran) Sets with many pairs of orthogonal vectors over finite fields Abstract: Let n be a positive integer and B be a non-degenerate symmetric bilinear form on Fq, where q is an odd prime power and Fq is the finite field with q elements. We determine the largest possible cardinality of a subset S ⊂ Fq such that |{B(x, y) |x, ...
