background in this study, we evaluated the prevalence of the most common mutations occurring in enhancer ii (enhii), basal core promoter (bcp), precore (pc), and core (c) regions of hepatitis b virus (hbv) genome. objectives we also investigated the correlation between hbv variants, their genotypes, and patients’ hbe antigen (hbeag: soluble shape of the capsid antigen) status patients and metho...

objectives the present study aimed to evaluate the genotypes and prevalence of mutations in a segment of s and rt gene in hbv isolates in southern khorasan, iran. methods this was a population-based study comprising 5,235 randomized samples for hbv screening. a nested-polymerase chain reaction (pcr) test was followed by direct sequencing, and the sequences blast with present sequences of ncbi d...

We find M-theory (Type IIA) duals for compactifications of the 9d CHL string to 5d (4d) on K3 (K3 × S 1). The IIA duals are Calabi-Yau orbifolds with nontrivial RR U (1) In ten dimensions, the consistent critical string theories with (at least) sixteen super-charges have been known since the 1980s. There are (after accounting for the S-duality of the two SO(32) theories) four. In D = 9, in addi...

We present a unified approach to quantum teleportation in arbitrary dimensions based on the Wigner-function formalism. This approach provides us with a clear picture of all manipulations performed in the telepor-tation protocol. In addition within the framework of the Wigner-function formalism all the imperfections of the manipulations can be easily taken into account. All quantum mechanical ph...

Background: Mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene can cause congenital bilateral absence of vas deferens. Yet, the spectrum and frequency of CFTR mutations in Indian males with congenital absence of vas deferens (CAVD) is unknown. Materials and Methods: We investigated 50 Indian males, diagnosed with unilateral or bilateral absence of vas deferens at t...

I N 1994 AIR FORCE Special Opera tions Com mand stood up the 6th Special Op­ era tions Squadron (6 SOS), the first-­ ever USAF squadron dedicated to the for eign inter nal defense (FID) mission area. With roots in special air warfare dating back to the Vietnam War and even as far back as the Second World War, the 6 SOS was created to advise, train, and assist for­ eign aviation forces in the ap...
