We have fabricated and characterized the field effect transistors having an epitaxial-graphene channel grown on Si substrates. Epitaxial graphene is usually formed on SiC substrates by ultrahigh-vacuum (UHV) annealing. We used an approach to grow 3C�

We experimentally observed the fast relaxation and relatively slow recombination dynamics of photogenerated electrons/holes in a heteroepitaxial graphene-on-Si material under pumping with a 1550-nm, 80-fs pulsed fiber laser and probing with the corre

A 40-year-old woman who had bilateral swelling in the eyelids and submandibular region was admitted. Clinical findings suggested she had primary Sjogren's syndrome. Laboratory data showed glucosuria, positive CRP (0.50 mg/dl), liver dysfunction (AST

Diffuse large B-cell lymphoma (DLBCL) can be divided into prognostically important categories such as germinal center B (GCB)-like and non-GCB-like groups. The t(14;18)(q32;q21) translocation defines a unique subset of DLBCL cases with a GCB gene exp
