We report on XMM-Newton observations of the galactic supersoft X-ray source RX J0925.7-4758. The RGS spectrum exhibits a wealth of spectral features from iron and oxygen. XMM-Newton data confirm the finding of previous Chandra HETGS/MEG observations that NLTE models of hot white dwarf atmospheres fail to represent the complex spectrum. There are clear evidences for P Cygni profiles with wind ve...
This paper describes the authors’ experiences attacking the IBM 4758 CCA, used in retail banking to protect the ATM infrastructure. One of the authors had previously proposed a theoretical attack to extract DES keys from the system, but it failed to take account of realworld banking security practice. We developed a practical scheme that collected the necessary data in a single 10-minute sessio...
The BG1 gene is a disease resistance candidate in chicken, which located the MHC region. mechanism of known as an inhibitor T lymphocyte cell activation. This study aims to identify diversity SNP IPB-D2 chicken line. for new line from cross IPB-D1 was selected high body and good productivity. A total 27 DNA samples (G0) chickens 58 (G2) were sequenced genes. found 6 point mutations (g.4489 G>...
Endoxylanases are a group of enzymes that hydrolyze the beta-1, 4-linked xylose backbone of xylans. They are predominantly found in two discrete sequence families known as glycoside hydrolase families 10 and 11. The Streptomyces lividans xylanase Xyl10A is a family 10 enzyme, the native structure of which has previously been determined by x-ray crystallography at a 2.6 A resolution (Derewenda, ...

BACKGROUND The prevalence of adult obesity is higher in women than men in most countries. However, the pathways that link female sex with excess obesity are still not fully understood. We examine whether socioeconomic and behavioural factors may mediate the association between sex and obesity in the Saudi Arabian setting where there is female excess in obesity. METHODS We performed a mediatio...
BACKGROUND Crohn's disease (CD) and ulcerative colitis (UC) challenge economies worldwide. Detailed health economic data of DRG based academic inpatient care for inflammatory bowel disease (IBD) patients in Europe is unavailable. METHODS IBD was identified through ICD-10 K50 and K51 code groups. We took an actual costing approach, compared expenditures to G-DRG and non-DRG proceeds and perfor...
A comparison is made between the properties of CAL 83, CAL 87, RX J0513.9−6951, 1E 0035.4−7230 (SMC 13), RX J0019.8+2156, and RX J0925.7−4758, all supersoft X-ray binaries. Spectra with the same resolution and wavelength coverage of these systems are compared and contrasted. Some new photometry is also presented. The equivalent widths of the principal emission lines of H and He II differ by mor...
In Private Information Retrieval (PIR), a user obtains one of N records from a server, without the server learning what record was requested. Recent research in “practical PIR” has limited the players to the user and server and limited the user’s work to negotiating a session key (eg. as in SSL)— but then added a secure coprocessor to the server and required the secure coprocessor to encrypt/pe...
