Using QCD factorization for the hadronic matrix elements, we show that existing data, inparticular the branching ratios BR ( B →J/ψK) and BR ( B →J/ψπ), can be accounted for in this approach.We analyze the decay B J /K( ) within the framework of QCD factorization. The calculation of therelevant hard-scattering kernels for twist-2 and twist-3 is completed. We calculate this decay in a special scale( mb ) and in two schemes for Wilson coefficients in NLO. We consider three functions for J / . Thetwist-3 contribution involves the logarithmically divergent integral, we consider H 0 the cancelingdivergent. The obtained results are in agreement with available experimental data.

In this paper, we find the number of sides of circuits in suborbital graph for the normalizer of0 (m) in PSL(2,), where m will be of the form 2p2 , p is a prime and p 1 mod 4. In addition, wegive a number theoretical result which says that the prime divisors p of 2u2 2u 1 are of the formp 1 mod 4.

The most current pursuit algorithms for moving targets which are presented so far in the literatureare Pure Pursuit and Pure Rendezvous navigations. Recently, one of the present authors has introduced ageometric model for the Pure Pursuit navigation algorithm. Here, in this paper, we study a new algorithm forthe pursuit navigation problem which is a combination of both of the above algorithms. We study itsgeometric properties, as well as the trajectories as time optimal paths. Finally, we compare this algorithm withwell-known algorithms in some real examples.

In this paper, we study L1 -solutions of the following two-direction poly-scale refinement equationWe prove that the vector space of all L1 -solutions of the above equation is at most one-dimensional andconsists of compactly supported functions of constant sign. We also show that any- L1 solution of the aboveequation is either positive or negative on its support under a special assumption. With regard to the -solutions of the equation, some simple sufficient conditions for the existence of nontrivial -solutions andthe nonexistence of such solutions are given.

We develop a two phase sampling procedure to determine the sample size necessary to estimatethe population mean of a normally distributed random variable and show that the resulting estimator has preassigned variance and is unbiased under a regular condition. We present a necessary and sufficient condition under which the final sample mean is an unbiased estimator for the population mean.
