In this paper we consider the Anderson type model and show that the density of states is analytic in an interval for large disorder. The examples we have allow for the single site distributions to have some singular components. We also allow non-nearest neighbour hopping terms.

From a hopping rate equation for disordered materials we derive a macroscopic drift{di usion equation. For this purposes two space{time scales are simultaneously considered. The microscopic dynamics is characterized by the distribution of localized states and the hopping rate. On the macroscopic space scale both the hopping rate and the disordered material are allowed to be inhomogeneous.

the objective of this study was to determine the phenotypic characteristics of kpc-producing pseudomonas aeruginosa and acinetobacter baumannii isolates. a case report study was performed at a tertiary burn care centre in tehran,  iran.  nine  isolates  of pseudomonas  aeruginosa  and  acinetobacter baumannii from a hospitalized case were isolated. the identity of isolates was confirmed and the...

The seismic behavior and plasticity spreading of a neotype column-slab high pier are researched in this paper. Four scale model tests of a web slab with two boundary columns are carried out under cyclic inelastic lateral displacements simulating seismic response. The test results show that the neotype column-slab high pier has strong and stable bearing capacity, good ductility, and energy dissi...

Controlling Ebola outbreaks and planning an effective response to future emerging diseases are enhanced by understanding the role of geography in transmission. Here we show how epidemic expansion may be predicted by evaluating the relative probability of alternative epidemic paths. We compared multiple candidate models to characterize the spatial network over which the 2013-2015 West Africa epi...

the principles of infection control should be seriously taken into account by the dentists to prevent the spread of infectious diseases and the consequent risks. the aim of the present study was to determine the knowledge of the general dentists of kermanshah about the principles of infection control in 2012. this descriptive cross-sectional study was carried out on 95 general dentists in kerms...

This paper analyses the determinants of variation in the yield spread (credit spread) between government bonds and corporate bonds in Japan's bond market after 1997. The authors conduct empirical tests on the relationship between credit spreads and several economic and financial variables. A key finding is that default risk and the overall financial situation in Japan were the most significant ...

This paper investigates the determinants of credit spread changes on bonds denominated in Euro. The analysis is carried out using a panel data on Euro bonds. We try to asses the relative importance of market and idiosyncratic factors in explaining the movements in credit spread. Because credit spread changes can be easily viewed as an excess return of corporate bonds over treasury, we adopt a f...

In large populations of autonomous individuals, the propagation of ideas, strategies or infections is determined by the composite effect of interactions between individuals. The propagation of concepts in a population is a form of influence spread and can be modelled as a cascade from a set of initial individuals through the population. Understanding influence spread and information cascades ha...
