Dynamic querying (DQ) is a search technique used in unstructured peer-topeer (P2P) networks to minimize the number of nodes that is necessary to visit to reach the desired number of results. In this paper we introduce the use of the DQ technique in structured P2P networks. In particular, we present a P2P search algorithm, named DQ-DHT (Dynamic Querying over a Distributed Hash Table), to perform...

Celiac disease also known as gluten-sensitive enteropathy is characterized by intestinal mucosal damage and malabsorption from dietary intake of wheat, rye or barley. Symptoms may appear with introduction of cereal in the first 3 years of life. A second peak in symptoms occurs in adults during the third or forth decade and even as late as eight decade of life. The prevalence of this disease is ...

Two different dual phase steels were prepared from low carbon manganese steel after the elimination of the banding using the direct quenching (DQ) and the step quenching (SQ) procedures. Different heat treatments resulted in different martensite morphologies, microstructures and mechanical properties. The heat treatments were designed in such a way to obtain a 0.25 volume fraction of martensite...

Existing algorithms for accurately estimating the f( ) singularity spectrum from the samples of generalized dimensions Dq of a multifractal chaotic time series use either linear interpolation of the known Dq values or nely sample the Dq curve. Also, the derivative in the expression for Legendre transform necessary to go from Dq to f( ) is approximated using rst order centered di erence equation...

BACKGROUND AND OBJECTIVES The current allocation algorithm for deceased donor kidney transplantation takes into consideration HLA mismatches at the ABDR loci but not HLA mismatches at other loci, including HLA-DQ. However, the independent effects of incompatibilities for the closely linked HLA-DQ antigens in the context of HLA-DR antigen matched and mismatched allografts are uncertain. We aimed...

The MHC of cattle encodes two distinct isotypes of class II molecules, DR and DQ. Unlike humans, cattle lack the DP locus and about half the common haplotypes express duplicated DQ genes. The number and frequency of DQA and DQB alleles means that most cattle are heterozygous. If inter- and/or intrahaplotype pairing of DQA and DQB molecules occurs, cattle carrying DQ-duplicated haplotypes may ex...

DQ-113 is a new quinolone with potent activity against gram-positive pathogens. The in vivo activity of DQ-113 against Streptococcus pneumoniae was compared with those of gatifloxacin and ciprofloxacin in a mouse model. For this purpose, two strains of S. pneumoniae were used: penicillin-susceptible S. pneumoniae (PSSP) and penicillin-resistant S. pneumoniae (PRSP). The survival rates of mice i...

A diet questionnaire (DQ) designed to assess habitual diet and phyto-oestrogen intake was developed. This study aimed to examine the validity of the DQ in men, with and without having prostate cancer. The DQ was validated against alkylresorcinol metabolites measured in urine as objective biomarkers of whole grain wheat and rye (WG) intake, and a 4-d estimated food record (FR) was used for relat...

The increasing availability of digitized biodiversity data worldwide, provided by an increasing number of institutions and researchers, and the growing use of those data for a variety of purposes have raised concerns related to the "fitness for use" of such data and the impact of data quality (DQ) on the outcomes of analyses, reports, and decisions. A consistent approach to assess and manage da...

OBJECTIVE Coeliac disease (CD) is associated with HLA-DQ2 and DQ8. The clinical picture is variable and certain human leucocyte antigen (HLA) DQ/DR combinations have a higher relative risk (RR) for CD than others. Moreover, the HLA-DQ gene-dose effect has an impact on the strength of the gluten-specific T-cell response and thus may correlate with clinical presentation and severity of CD. The ai...
