We study security issuers’ decisions on whether to pool assets when facing counterparties endowed with market power, as is common in over-the-counter markets. Our analysis reveals how buyers’ power may render the pooling of suboptimal — both privately and socially particular, potential gains from trade are large. Pooling then reduces elasticity volume relevant part payoff distribution, exacerba...

We consider the continuous-time random walk of a particle in a two-dimensional self-affine quenched random potential of Hurst exponent H>0 . The corresponding master equation is studied via the strong disorder renormalization procedure introduced in Monthus and Garel [J. Phys. A: Math. Theor. 41, 255002 (2008)]. We present numerical results on the statistics of the equilibrium time t(eq) over t...

The aim of this work is to propose a method to establish trust at bootload level in cloud computing environment. This work proposes a game theoretic based approach for achieving trust at bootload level of both resources and users perception. Nash equilibrium (NE) enhances the trust evaluation of the first-time users and providers. It also restricts the service providers and the users to violate...

Yet there is no agreement among historians or archaeologists on the meaning of the words "Celtic" or "Anglo-Saxon." What is more, new evidence from genetic analysis (see note below) indicates that the Anglo-Saxons and Celts, to the extent that they can be defined genetically, were both small immigrant minorities. Neither group had much more impact on the British Isles gene pool than the Vikings...

The reasons why it is effective to estimate the chlorophyll-a concentration with the ratio of spectral radiance reflectance at the red light region and near infrared regions were shown in theory using a two-flow model. It was found that all of the backscattering coefficients can consequently be ignored by using the ratio of spectral radiance reflectance, which is the ratio of the upward radianc...

In Huang and Weng (2004), Huang and Weng introduced pooling spaces, and constructed pooling designs from a pooling space. In this paper, we introduce the concept of pooling semilattices and prove that a pooling semilattice is a pooling space, then show how to construct pooling designs from a pooling semilattice. Moreover, we give many examples of pooling semilattices and thus obtain the corresp...

background: many studies have been showed that certain illnesses including fungi and bacterial infections can be transmitted to human by contaminated swimming pools water. the main objective of the present study was to detect microbial (bacterial and fungi) and chemical (ph and chlorine levels) pollutions of the all swimming pools water in hamadan city, iran . methods: this study was a cross-se...
