We employ first-principles density functional theory calculations to study the surface reconstruction, energetic stability, and electronic structure of diamond C(331) surface. Spontaneous formation of graphene-like stripes on the reconstructed surface is found to occur as the surface terrace C atoms transform from sp3 to sp2 hybridization upon structural relaxation. The comparison of the calcul...

A mechanism for generating small tree-level Majorana mass for neu-trinos is implemented in the 331 Model. No additional fermions or scalars need to be added, and no mass scale greater than a few TeV is invoked.

On the biotransformation of phenol and monofluorophenols by the cultured cells of Eucalyptus perriniana, phenyl and fluorophenyl b-D-glucosides were isolated after a 1-h incubation. Especially, the yield of 2-fluorophenol is higher than those of the other substrates, i.e., phenol, 3and 4-fluorophenols. These results indicated that E. perriniana cells selectively glycosylate the hydroxyl group o...

MicroRNAs (miRNAs) are a class of small endogenous RNAs that play important regulatory roles by targeting mRNAs for cleavage or translational repression. miRNAs act in diverse biological processes including development, cell growth, apoptosis, and hematopoiesis, suggesting their association with cancer. We determined the miRNA expression profile of chronic and acute lymphocytic leukemias (CLL a...
