Dear Editor, The spread of the emerging zoonotic arboviral agent, Zika virus (ZIKV), in the Americas and its association with congenital abnormalities, 1,2 including in utero growth restriction, placental insuffi-ciency, microcephaly and fetal death, as well as neurological conditions, such as Guillain Barré syndrome, has led the World Health Organization(More)
We present a novel implementation of the pairwise DNA sequence alignment problem other than the Dynamic programming solution presented by Smith Waterman Algorithm. The proposed implementation uses CUDA; the parallel computing platform and programming model invented by NVIDIA. The main idea of the proposed implementation is assigning different nucleotide(More)
MrBayes is model-based phylogenetic inference tool using Bayesian statistics. However, model-based assessment of phylogenetic trees adds to the computational burden of tree-searching, and so poses significant computational challenges. Graphics Processing Units (GPUs) have been proposed as high performance, low cost acceleration platforms and several(More)
We report electrical transport measurements on a suspended ultra-low-disorder graphene nanoribbon (GNR) with nearly atomically smooth edges that reveal a high mobility exceeding 3000 cm 2 V −1 s −1 and an intrinsic band gap. The experimentally derived band gap is in quantitative agreement with the results of our electronic structure calculations on chiral(More)
BACKGROUND More than ten subgenotypes of genotype C Hepatitis B virus (HBV) have been reported, including C1 to C16 and two C/D recombinant subgenotypes (CD1 and CD2), however, inconsistent designations of these subgenotypes still exist. METHODOLOGY/PRINCIPAL FINDINGS We performed a phylogenetic analysis of all full-length genotype C HBV genome sequences(More)
