Direct numerical test of the B-G-K model equation by the DSMC method
No full textIn the present paper the rarefied gas how caused by the sudden change of the wall temperature and the Rayleigh problem are simulated by the DSMC method which has been validated by experiments both in global flour field and velocity distribution function level. The comparison of the simulated results with the accurate numerical solutions of the B-G-K model equation shows that near equilibrium the BG-K equation with corrected collision frequency can give accurate result but as farther away from equilibrium the B-G-K equation is not accurate. This is for the first time that the error caused by the B-G-K model equation has been revealed

CORPORATE GOVERNANCE AND CAPITAL MARKETS: A CONCEPTUAL FRAMEWORK
No full textThis paper outlines a conceptual framework of the relationship between corporate governance and two important determinants of capital market development namely, a firm’s access to finance, and its financial performance. The framework assumes that a firm’s corporate governance is simultaneously determined by a group of related governance components and other firm characteristics. Whilst the capital markets play a crucial role in enhancing corporate governance standards, the effectiveness and credibility of such effort might be constrained by poor firm-level corporate governance. Moreover, the cause and effect relationship can work in the opposite direction e.g. firm-level corporate governance quality can enhance both the firm’s ability to gain access to finance and its financial performance, which eventually lead to capital market development. The framework is primarily based on the economic approaches to corporate governance, although it recognises part of the assumptions of the stakeholder theory and the political economy aspects of corporate governance

A study on the reliability of consecutive k-Out-of-n: G systems based on Copula
No full textThe computation of reliability characteristics of a system that consists of dependent components is sometimes difficult especially when the type of dependence is not known. This article introduces the copula method to calculate the reliability of dependent consecutive k-out-of-n: G systems. The components in these systems are dependent on each other and the dependency may be either linear or nonlinear. The copula is a popular tool for modeling the dependence structure of data. It contains the information about the dependency structure of a vector of random variables and can capture nonlinear dependence. Based on the copula theory, the article analyzes the consecutive k-out-of-n: G systems and gets the reliability indexes. Finally, some numerical examples are presented to illustrate the results obtained in this article.Peer reviewe
G. K. Chesterton Portrait
No full textThis item is an oil portrait of the British author G. K. Chesterton (1874–1936). It was painted by the Irish artist Edwin Swan. The portrait measures approximately 44.5 by 34 inches. This portrait is based on a black-and-white photograph of Chesterton taken in 1935 by the British photographer Howard Coster (1885-1959). This is a posthumous portrait, painted after Chesterton’s death in 1936.
Edwin Swan was born in Ballyragget, Ireland, and studied at the Academie Julian in Paris. This portrait of Chesterton was once exhibited at the Royal Academy in 1940.https://collected.jcu.edu/chestertonimages/1000/thumbnail.jp
The numbers of dependent k-sets in a graph are log concave
No full textA set of vertices in a graph is said to be dependent if it is not independent. Let p(k)(G) denote the number of dependent sets of size k in the graph G. We show that, for any graph G, the sequence {p(k)(G)} is logarithmically concave.

Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
