Polymer state approximations of Schroedinger wave functions [PDF]

open access: yes, 2006
It is shown how states of a quantum mechanical particle in the Schroedinger representation can be approximated by states in the so-called polymer representation.

Genetic Characterization of ExPEC-Like Virulence Plasmids among a Subset of NMEC

open access: yesPLOS ONE, 2016
Neonatal Meningitis Escherichia coli (NMEC) is one of the most common causes of neonatal bacterial meningitis in the US and elsewhere resulting in mortality or neurologic deficits in survivors. Large plasmids have been shown experimentally to increase the virulence of NMEC in the rat model of neonatal meningitis.

Bacteriocin-encoding genes and ExPEC virulence determinants are associated in human fecal Escherichia coli strains [PDF]

open access: yesBMC Microbiology, 2014
A set of 1181 E. coli strains of human fecal origin isolated in the South Moravia region of the Czech Republic was collected during the years 2007-2010. Altogether, 17 virulence determinants and 31 bacteriocin-encoding genes were tested in each of them.The occurrence of bacteriocin-encoding genes was found to be positively correlated with the ...

Distribution and virulence properties of extra-intestinal pathogenic Escherichia coli in Turkey

open access: yesMicrobiologia Medica, 2016
Extraintestinal pathogenic Escherichia coli (ExPEC) is a universal pathogen which causes variety of diseases that impact on people of all ages. ExPEC strains are genetically diverse and associated virulence factors contribute to the wide spectrum of ...

Distances in random graphs with finite variance degrees

open access: yes, 2004
In this paper we study a random graph with $N$ nodes, where node $j$ has degree $D_j$ and $\{D_j\}_{j=1}^N$ are i.i.d. with $\prob(D_j\leq x)=F(x)$. We assume that $1-F(x)\leq c x^{-\tau+1}$ for some $\tau>3$ and some constant $c>0$.

Spondylodiscitis in a healthy 12-year-old girl with Extraintestinal pathogenic Escherichia coli (ExPEC) bacteraemia [PDF]

open access: yesBMC Infectious Diseases, 2017
Escherichia coli (E. coli) is rarely implicated in bone or joint infections in children.We discuss the case of a healthy 12-year-old girl with an E. coli bacteraemia and a T11-T12 spondylodiscitis revealed by magnetic resonance imaging. The strain harboured serogroup O1:K1 and virulence factors common to highly virulent extra intestinal pathogenic E ...
