For any operator on integer-valued functions, we say that #P is closed under in context PF#P if, for every f 2 #P, f] belongs to PF #P. For several operators , it is shown that the closure properties of #P under in the above sense is closely related to the relationships between P #PP1] and higher classes such as PH PP and PP PP .

يهدف البحث الى تسليط الضوء على الموقف البريطاني من الازمة العراقية -الكويتية في حزيران عام 1961 والتي برزت بعد التصريح الذي أدلى به رئيس الوزراء العراقي عبد الكريم قاسم المؤتمر الصحفي عقد الخامس والعشرين 1961، والذي طالب فيها السيادة الكويت، مما أدى بدء ازمة سياسية بين العراق والكويت مجددآ كانت لها صدى الصعيدين الدولي والإقليمي .

In recent years, the decay η → 3π has received considerable attention from experimental and theoretical side. It is of particular theoretical interest because it allows for the determination of (mu −md). In addition, for many years now theory has had difficulties to understand the slope of the neutral channel Dalitz plot distribution, which in contrast is very well measured. I discuss here the ...

We consider whether or not protein chains in the HP model have unique or few optimal foldings. We solve the conjecture proposed by Aichholzer et al. that the open chain L2k−1 = (HP )(PH) for k ≥ 3 has exactly two optimal foldings on the square lattice. We show that some closed and open chains have unique optimal foldings on the hexagonal and triangular lattices, respectively.
