B -> pi l nu at three lattice spacings

The increasing accuracy of experimental results for the exclusive, semileptonic decay B -> pi l nu requires a similarly accurate calculation of the hadronic matrix elements, to determine |Vub|. We present preliminary results for the form factors of the B to light meson decay mode. Using results from three lattices in the range 5.7 <= beta <= 6.1 we study the dependence on the lattice spacing.Comment: LATTICE98(heavyqk), LaTeX, 3 pages, 4 postscript figures, uses espcrc2.st

Persistent issues in encryption software: A heuristic and cognitive walkthrough

The support information accompanying security software can be difficult to understand by end-users, who have little knowledge in cyber security. One mechanism for ensuring the integrity and confidentiality of information is encryption software. Unfortunately, software usability issues can hinder an end-user’s capability to properly utilise the security features effectively. To date there has been little research in investigating the usability of encryption software and proposing solutions for improving them. This research paper analysed the usability of encryption software targeting end-users. The research identified several issues that could impede the ability of a novice end-user to adequately utilise the encryption software. A set of proposed recommendations are suggested to improve encryption software which could be empirically verified through further research

Public and private partnership and business actors in political processes concerning military issues

Purpose: The article researches the actual issues of developing partnership and cooperation between the state and private business in matters of production and modernization the military-industrial complex of Russia. The main object of the research is the Russian NAVY. The subject of the research is the comparison of the Russian and US NAVY modernization in the context of public and private partnership. Design/Methodology/Approach: The authors used a wide range of methodological tools in the course of the study. The method of economic analysis, the method of structural analysis, the statistical method and the method of mathematical comparison were used. Findings. Studying the role of business actors in the national rearmament programmes in Russia the authors revealed such key indicators as economic viability and financial efficiency of programme implementation. A comparative analysis of budget and private funding of the similar US programme was conducted and statistical data supporting the main findings of the study were introduced. Practical Implications: The development of cooperation between business and the MIC at the state level should go along the path of creating conditions for public-private partnerships (PPPs) - a set of organizational, legal, financial and economic relations and joint actions of the state and private business aimed at achieving the goals of the state economic policy in order to address socially significant tasks on mutually beneficial conditions. Originality/Value: The authors’ conclusion that state’s financial and economic policy in the field of defense and modernization of the domestic defense industry has all chances to become the locomotive of the country’s industrial, scientific and technological development gives new horizons for discussing the most appropriate rearmament strategy.peer-reviewe

New Results and Matrix Representation for Daehee and Bernoulli Numbers and Polynomials

In this paper, we derive new matrix representation for Daehee numbers and polynomials, the lambda-Daehee numbers and polynomials and the twisted Daehee numbers and polynomials. This helps us to obtain simple and short proofs of many previous results on Daehee numbers and polynomials. Moreover, we obtained some new results for Daehee and Bernoulli numbers and polynomials

New Results on Higher-Order Daehee and Bernoulli Numbers and Polynomials

We derive new matrix representation for higher order Daehee numbers and polynomials, the higher order lambda-Daehee numbers and polynomials and the twisted lambda-Daehee numbers and polynomials of order k. This helps us to obtain simple and short proofs of many previous results on higher order Daehee numbers and polynomials. Moreover, we obtained recurrence relation, explicit formulas and some new results for these numbers and polynomials. Furthermore, we investigated the relation between these numbers and polynomials and Stirling numbers, Norlund and Bernoulli numbers of higher order. The results of this article gives a generalization of the results derived very recently by El-Desouky and Mustafa [6]
