The maximum oscillation frequency (fmax) quantifies the practical upper bound for useful circuit operation. We report here an fmax of 70 GHz in transistors using epitaxial graphene grown on the C-face of SiC. This is a significant improvement over Si-face epitaxial graphene used in the prior high frequency transistor studies, ...

Closely related species often show adjacent geographic distributions, albeit with some overlap. This contiguity is thought to result from secondary contact between (spatially separated) diverging groups or from parapatric speciation. Fights between males of closely related species will affect their chance to mate with females of the other species, which ...

The phase transition, amorphization, and crystallization behaviors of the topological insulator bismuth selenide (Bi(2)Se(3)) were discovered by performing in situ high-pressure angle-dispersive x-ray diffraction experiments during an increasing, decreasing, and recycling pressure process. In the compression process, Bi(2)Se(3) transforms from the original rhombohedral structure (phase I(A)) to a monoclinic structure (phase II) ...

Pneumopericardium is a rare clinical finding with various etiologies. Pneumopericardium ranges from an asymptomatic to life-threatening condition, e.g., in cases of cardiac tamponade. The underlying etiology should be sought so that treatment can be expedited. Pneumopericardium may result from traumatic and nontraumatic etiologies. Although the mortality associated with pneumopericardium is ...

Maintenance of intracellular chloride (Cl(-)) concentration ([Cl(-)]i) is critical for volume regulation and determines the effects of γ-aminobutyric acid (GABA) and glycine-mediated neurotransmission. Cation-chloride cotransporters (CCC) transport Cl(-) together with sodium (Na(+)), potassium (K(+)), or both, across plasma membranes and have an important role in maintenance [Cl(-)]i. The CCC in ...

RATIONALE: Despite recognition of the importance of the longer-term consequences of stroke, services addressing these needs remain poorly developed. There are persuasive arguments that a community-based orientation to poststroke care, to assess, support, and coordinate relevant services, might be more helpful in minimizing longer-term stroke morbidity. To address this, an ...

Both spondylosis and diffuse idiopathic skeletal hyperostosis (DISH) are prevalent in humans and are considered distinct entities. Nowadays, the term spondylosis is in the biomedical literature mostly used when also degenerative disc disease is present. In companion animals, many reports on spondylosis, often without intervertebral disc degeneration, are described. The ...
