This paper presents a novel method for determining the probability that a supernova candidate belongs to a known supernova type (such as Ia, Ibc, IIL, etc.), using its photometric information alone. It is validated with Monte Carlo, and both spaceand groundbased data. We examine the application of the method to well-sampled as well as poorly sampled supernova light curves and investigate to wha...
Hepatitis B virus (HBV) has been classified into eight genotypes (A-H) based on genome sequence divergence. Genotypes of HBV have distinct geographical distributions, and two genotypes account for most HBV worldwide. Hepatitis B e antigen expression lasts longer and liver disease is more severe with graver outcomes in carriers of genotype C than B in Asia. Accumulating lines of evidence indicat...
A total of twenty-two strict anaerobic and Gram-positive Bifidobacteria, identified as B. adolescentis, B.pseudocatenulatum, or B. longum, were isolated from healthy adult Koreans. We here investigated the cellmorphology, antimicrobial resistance patterns to novel antibiotics and genotypic differentiation ofBifidobacteria assessing repetitive DNA element PCR (rep-PCR) fingerpr...

Background and Objective: Host genetic factors such as cytokine gene polymorphisms as well as Helicobacter pylori (H. pylori) infection have been found to be associated with gastric cancer risk . Interleukin 1 is a pro-inflammatory cytokine involved in H. pylori-induced gastric inflammation. Therefore, w...
We report on VLBI observations of the Type I b/c supernova 2001em, three years after the explosion. It had been suggested that SN 2001em might be a jet-driven gamma ray burst (GRB), with the jet oriented far from the line of sight so that the GRB would not be visible from earth. To test this conjecture, we determined the size of SN 2001em. It is only marginally resolved at our resolution of ∼0....
Live 60Fe has recently been detected in a deep-ocean ferromanganese crust, isolated in layers dating from about 3 Myr ago. Since 60Fe has a mean life of 2.2 Myr, a nearEarth supernova is the only likely source for such a signal, and we explore here the consequences of a supernova origin. We combine the 60Fe data with several supernova nucleosynthesis models to calculate the supernova distance a...
BACKGROUND AND AIMS Previous studies have demonstrated the dominance of genotype D subtype ayw in patients with hepatitis B virus infection in Turkey. The aim of the present study is to report, for the first time, genotype A2 subtype adw2 of hepatitis B virus in a patient who is an inactive hepatitis B carrier in Turkey. MATERIALS AND METHODS Hepatitis B virus DNA isolated from the serum samp...
