Survey of policy for MRSA screening in English cataract surgical units and changes to practice after updated National guidelines
National guidelines on MRSA (methicillin-resistant Staphylococcus aureus) screening policy in England have changed on a number of occasions, but there is limited data on its influence at a local level. The aim of this study was to determine if changes in National policy influenced preoperative screening of cataract patients for MRSA
Foreign competition in U.S. banking markets
Foreign penetration of U.S. wholesale banking already exceeds that of most other industry groups; unless market capitalization ratios for U.S. banks go up—or down for foreign banks—this trend is likely to continue.Banks and banking, Foreign - United States
Random Growth Models
The link between a particular class of growth processes and random matrices
was established in the now famous 1999 article of Baik, Deift, and Johansson on
the length of the longest increasing subsequence of a random permutation.
During the past ten years, this connection has been worked out in detail and
led to an improved understanding of the large scale properties of
one-dimensional growth models. The reader will find a commented list of
references at the end. Our objective is to provide an introduction highlighting
random matrices. From the outset it should be emphasized that this connection
is fragile. Only certain aspects, and only for specific models, the growth
process can be reexpressed in terms of partition functions also appearing in
random matrix theory.Comment: Review paper; 24 pages, 4 figures; Minor correction
On Time Correlations for KPZ Growth in One Dimension
Time correlations for KPZ growth in 1+1 dimensions are reconsidered. We
discuss flat, curved, and stationary initial conditions and are interested in
the covariance of the height as a function of time at a fixed point on the
substrate. In each case the power laws of the covariance for short and long
times are obtained. They are derived from a variational problem involving two
independent Airy processes. For stationary initial conditions we derive an
exact formula for the stationary covariance with two approaches: (1) the
variational problem and (2) deriving the covariance of the time-integrated
current at the origin for the corresponding driven lattice gas. In the
stationary case we also derive the l arge time behavior for the covariance of
the height gradients
SBML Reaction Finder: Retrieve and extract specific reactions from the BioModels database
Summary: The SBML Reaction Finder (SRF) application leverages the deep semantic annotations in the BioModels database to provide efficient retrieval and extraction of individual reactions from SBML models. We hope that the SRF will be useful to quantitative modelers who seek to accelerate their modeling efforts by reusing previously published representations of specific chemical reactions.

Availability and Implementation: The SRF is open source, coded in Java, and distributed under the Mozilla Pubic License Version 1.1. Windows, Macintosh and Linux distributions are available for download at
