background: the blocking of nitric oxide synthase (nos) activity may reason vasoconstriction with formation of reactive oxygen species. propolis has biological and pharmacological properties, such as antioxidant. the aim of this study was to examine the antioxidant effects of propolis which natural product on biochemical parameters in brain and lung tissues of acute nitric oxide synthase inhibi...

For matrices with displacement structure, basic operations like multiplication, in4 version, and linear system solving can all be expressed in terms of the following task: evaluate the 5 product AB, where A is a structured n × n matrix of displacement rank α, and B is an arbitrary 6 n × α matrix. Given B and a so-called generator of A, this product is classically computed with a 7 cost ranging ...

One of the major outstanding foundational problems about Boolean functions is the sensitivity conjecture, which asserts that the degree of a Boolean function is bounded above by some fixed power of its sensitivity. We propose an attack on the sensitivity conjecture in terms of a novel two-player communication game. A lower bound of the form nΩ(1) on the cost of this game would imply the sensiti...
