accessory gene regulator (agr locus) is a global regulator of many virulence gene expressions instaphylococcus aureus. four interference classes related to genetic polymorphisms in the agr locus have sofar been described. in the present study, the agr locus specificity groups were studied within a total of 43 s.aureus isolates which were isolated from ewes with mastitis in three regions in the ...

We investigate the concepts of past, present, and future that build upon a modal distinction between the settled past and the open future. The concepts are defined in terms of a pre-causal ordering and of qualitative differences between alternative histories. Finally, we look what an event’s past, present, and future look like in the so-called Minkowskian Branching Structures, in which historie...

Identifying the best way to organize the IS functions within an interprise has been a critical IS management issue since the mid-1980s. Yet to date, MIS researchers have offered little empirical evidence on which to base guidelines for the practitioner. This study seeks to explain a firm’s IS organization design decision for a decentralized, centralized, or "hybrid" locus of responsibility from...

A robotic platform controlled by a neuronal simulation is presented for studying the mechanisms underlying the ring of hippocampal place cells and how they support navigation. The sensors on the robot provide visual, odometric and short-range proximity information which are combined to estimate the distance of the walls of the enclosure from the robot and its current heading direction. These in...

In [D1, Thm. 8.4], Deligne proved the following beautiful estimate for exponential sums in n ≥ 1 variables. Given a polynomial f(x1, . . . , xn) in n variables over k of some degree d ≥ 1, write it as f = Fd + Fd−1 + · · · F0 with Fi homogeneous of degree i. Suppose that the following two conditions are satisfied. (1) The degree d is prime to p := char(k). (2) The locus Fd = 0 is a nonsingular ...

In recent years, the rapid development of electronic commerce in China has made online shopping one of the most important shopping ways. However, there are more and more service failures on online shopping, and complaints about them are increasing, which will hinder the development of e-commerce in China. After service failure occurring, customers are going to decide the parties who are respons...

The differing attitudes of Plato and Rousseau toward specialization and the division of labor color their views on who should formulate policy on political questions. In the theories of each thinker, the observations and evaluations made in such areas of social life as the production and exchange of services and material goods are carried over and applied to politics. In particular, the strikin...

Summary While the genome-wide association study (GWAS) is a powerful method to identify disease-associated variants, it does not directly address the biological mechanisms underlying such genetic association signals. Here, we present PGA, a Perl- and Java-based program for post-GWAS analysis that predicts likely disease genes given a list of GWAS-reported variants. Designed with a command line ...
