in this paper‎, ‎an efficient dropping criterion has been used to compute the iul factorization obtained from backward factored approximate inverse (bfapinv) and ilu factorization obtained from forward factored approximate inverse (ffapinv) algorithms‎. ‎we use different drop tolerance parameters to compute the preconditioners‎. ‎to study the effect of such a dropping on the quality of the ilu ...

objective(s) the immunoadjuvant potential of cross-linked dextran microspheres (cdm) as absorption enhancer and quillaja saponins (qs) as immunomodulator adjuvant was evaluated. materials and methods cdm loaded or tetanus-mixed toxoid (tt) or quillaja saponin (qs) were nasally administered to rabbits in dry powder form, three times in 2 weeks interval and serum igg and nasal lavage siga titers ...

results we found 28 cases with positive results for b. melitensis by multiplex pcr technique which was significantly different from of sat (p<0.05). six samples were positive for b. abortus by pcr. conclusion the results of present study showed that multiplex pcr assay is a rapid and sensitive technique for diagnosis of brucellosis compared to sat. however it is more accurate when coupled with ...

conclusions the present findings reveal a relatively high presence of anti-hev iggs and clearly indicate that hev infection is still present in northern algeria. further, the prediction of hev genotype using different antigens generated from the different hev genotypes shows that the causative strains are more likely to be of genotype 1. background two hepatitis e virus (hev) outbreaks occurred...

background rheumatoid arthritis (ra) is the most common chronic inflammatory disease of unknown etiology. in this regard, the role of bacterial superantigens (as an effective agent) were considered. objectives this study aimed to assess staphylococcal enterotoxin e in the blood of patients with rheumatoid arthritis. patients and methods a total of 83 blood samples of patients with ra were studi...

A type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. The aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. The hypercross-linked fiber adsorbent possesses a principall...

This paper describes a series of experiments in using logistic regression machine learning as a method for entity resolution. From these experiments the authors concluded that when a supervised ML algorithm is trained to classify a pair of entity references as linked or not linked pair, the evaluation of the model’s performance should take into account the transitive closure of its pairwise lin...
