We discuss recent results on the excitation spectra of B and D-mesons obtained in the framework of nonrelativistic lattice QCD in the quenched approximation. The results allow for the determination of the MS-mass of m b,MS (m b,MS ) = 4.34(7) GeV in O(α3s) in the perturbative matching. The determination of the decay constants fBs and fDs is discussed in detail. Results for the matrix elements o...

Recent lattice studies on (semi-)leptonic kaon decays towards a precise determination of |V us | are reviewed. Attention is given to recent unquenched calculations and consistency of their results with chiral perturbation theory. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

Abstract: Various issues of the design and application of multiobjective evolutionary algorithms to real-life optimization problems are discussed. In particular, questions on problem-specific data structures and evolutionary operators and the determination of method parameters are treated. Three application examples in the areas of constrained global optimization (electronic circuit design), se...

The rapid semi-micro determination of carbon by wet combustion of organic compounds (Van Slyke & Folch, 1940) has been subjected to various modifications, principally in the apparatus used (McCready & Hassid, 1942; Hockenhull, 1950). The apparatus is shown in Fig. 1, and is essentially that described by Hockenhull (1946; and personal communication), using the spiral bubbler modified from that o...

A semi-automated method for the determination of free fatty acids in plasma based on Mosinger's manual method (Mosinger, 1965) is described and the results of a comparison with Dole's titrimetric method (Dole, 1956) are presented. There is almost perfect correlation between the two methods, and the automated technique is simple, reliable, and significantly more accurate and precise than the tit...

determination of the amount of sugar in sugar beet is usually accomplished by polarimetric method in sugar industry. this method is not accurate due to impurities such as sodium, potassium and amino-nitrogen that are present and might cause some errors in the evaluation of the technical quality of sugar beet. in this research, 7309 samples of sugar beet from two semi- arid county, isfahan and c...

Let n and k be integers, with n > 1 and k > 0. An (n × n)/k semi-Latin square S is an n × n array, whose entries (called blocks) are k-element subsets of a set of size nk, the set of symbols of S, such that each symbol of S occurs exactly once in each row and exactly once in each column of S. Semi-Latin squares form a class of designs generalising Latin squares, and have applications in areas i...

In this paper, we introduce a class of cubic rotation symmetric (RotS) functions and prove that it can yield bent and semi-bent functions. To the best of our knowledge, this is the second primary construction of an infinite class of nonquadratic RotS bent functions which could be found and the first class of nonquadratic RotS semi-bent functions. We also study a class of idempotents (giving Rot...

All sophisticated methods for direct determination of methanol require advanced instruments and high technical knowledge which preparing them is very expensive in none developed and developing countries. This work reports a simple and efficient qualitative technique for semi determination of methanol content in herbal distillates by a new modified chromotropic acid method. The technique is base...
