The mixing angle θ13 is the last mixing angle to be measured. A non-zero value of θ13 is key to the possibility of measuring CP violation in future long-baseline accelerator experiments. The best limit on θ13 comes from the reactor experiment CHOOZ.[1] It has recently been recognized that the best possibility for rapidly measuring a non-zero value of the parameter θ13 comes from a new reactor e...

takab-e afshar in the north – west of iran. it is in a mountainous area near the cities of dandi in zanjan, and takab in west azerbaijan, lies a complex of historical and natural properties among which stands the world heritage properties of takht-e soleyman with all its features. the present protective buffers for this site have been defined without considering the natural and cultural landsca...

Answers are given to two questions concerning the existence of some sparse subsets of H = f0; 1; : : : ;H 1g N, where H is a hyper nite integer. In x1, we answer a question of Kanovei by showing that for a given cut U in H, there exists a countably determined set X H which contains exactly one element in each U -monad, if and only if U = a N for some a 2 H r f0g. In x2, we deal with a question ...

A quantization over a manifold can be seen as a way to construct a differential operator with prescribed principal symbol. The map from the space of principal symbols to the space of differential operators is moreover required to be a linear bijection. It is known that there is in general no natural quantization procedure. However, considering manifolds endowed with additional structures, such ...

Extending previous work of J. B. Olsson, cf. [7], [8], and of K. Erdmann and G. O. Michler, cf. [2], on the number of p-spin blocks of defect zero (p prime) of a double covering group of the symmetric group Sn, we prove that this number is positive for all n whenever p ≥ 7. More precisely, it is shown that sp(n) > 0 if p ≥ 7, where sp(n) denotes the number of bar partitions of n which are p̄-cores.
