Median inverse problem and approximating the number of $k$-median inverses of a permutation

open access: yes, 2011
We introduce the "Median Inverse Problem" for metric spaces. In particular, having a permutation $\pi$ in the symmetric group $S_n$ (endowed with the breakpoint distance), we study the set of all $k$-subsets $\{x_1,...,x_k\}\subset S_n$ for which $\pi ...

Adding a reward increases the reinforcing value of fruit [PDF]

open access: yes, 2017
Adolescents' snack choices could be altered by increasing the reinforcing value (RV) of healthy snacks compared with unhealthy snacks. This study assessed whether the RV of fruit increased by linking it to a reward and if this increased RV was comparable

Breakpoints for intravenously used cephalosporins in Enterobacteriaceae—EUCAST and CLSI breakpoints [PDF]

open access: yesClinical Microbiology and Infection, 2008
It has long been acknowledged that the cephalosporin breakpoints used in most European countries and the USA fail to detect many or most extended spectrum beta-lactamases (ESBLs) in Enterobacteriaceae and that all ESBLs are clinically significant. Therefore, microbiological laboratories have undertaken not only regular cephalosporin susceptibility ...

Rapid mapping of chromosomal breakpoints: from blood to BAC in 20 days [PDF]

open access: yes, 2009
Structural chromosome aberrations and associated segmental or chromosomal aneusomies are major causes of reproductive failure in humans. Despite the fact that carriers of reciprocal balanced translocation often have no other clinical symptoms or ...

Norovirus Recombination in ORF1/ORF2 Overlap

open access: yesEmerging Infectious Diseases, 2005
Norovirus (NoV) genogroups I and II (GI and GII) are now recognized as the predominant worldwide cause of outbreaks of acute gastroenteritis in humans. Three recombinant NoV GII isolates were identified and characterized, 2 of which are unrelated to any ...

Cellular system information capacity change at higher frequencies due to propagation loss and system parameters [PDF]

open access: yes, 2012
In this paper, mathematical analysis supported by computer simulation is used to study cellular system information capacity change due to propagation loss and system parameters (such as path loss exponent, shadowing and antenna height) at microwave ...
