We report on theoretical investigation of graphene based Field Effect Transistor (FET) structures for resonant absorption of terahertz (THz) radiation by the plasmons excited in the high sheet concentration and high carrier mobility active layers. Metallic grating gates with varying periods were used to couple the THz radiation into the plasmons in the active region of the devices. Such grating...

The chemical abundances in damped Lyman-a systems (DLAs) show more than 2 orders of magnitude variation at a given epoch, possibly because DLAs arise in a wide variety of host galaxies. This could significantly bias estimates of chemical evolution. We explore the possibility that DLAs in which H2 absorption is detected may trace cosmological chemical evolution more reliably since they may compr...

We tested the hypothesis that oxytocin-induced labor augmented IL-1beta-induced/-stimulated lung fluid absorption in preterm guinea pig fetuses. IL-1beta was administered subcutaneously daily to timed-pregnant guinea pigs for 3 days with and without simultaneous cortisol synthesis inhibition by metyrapone. At day 3, oxytocin was administered, and fetuses were delivered by abdominal hysterotomy ...

Abstract Some work in political methodology recommends that applied researchers obtain point estimates of quantities interest by simulating model coefficients, transforming these simulated coefficients into interest, and then averaging the (e.g., CLARIFY). But other advises to directly transform coefficient estimate interest. I out two approaches are not interchangeable examine their properties...

Majorana zero modes in condensed matter systems have been the subject of much interest recent years. Their non-Abelian exchange statistics, making them a unique state matter, and their potential applications topological quantum computation, earned attention from both theorists experimentalists. It is generally understood that order to form quasi-one-dimensional insulators, time-reversal symmetr...

BACKGROUND AND OBJECTIVES Previous research suggests that attention bias toward threat contributes to the development and maintenance of anxiety. The current study extends this work by mapping the neural correlates of experimentally-induced changes in attention bias. The study examines both behavioral and psychophysiological changes associated with experimentally-induced changes in threat bias....
