BACKGROUND In randomized controlled trials, participants cannot choose their preferred intervention delivery mode and thus might refuse to participate or not engage fully if assigned to a nonpreferred group. This might underestimate the true effectiveness of behavior-change interventions. OBJECTIVE To examine whether receiving interventions either matched or mismatched with participants' pref...
Abstract We present simulations of the partially coherent undulator radiation (UR) propagation through several hard X-ray beamlines at NSLS-II, performed with SRW code, adopting two different memory- and CPU-efficient strategies / algorithms for mode decomposition (CMD). One these employs subtraction quadratic phase terms from 4D cross spectral density (CSD) a non-zero radius wavefront curvatur...
Delay analysis providing an alternative physical explanation on carrier transport, which may be more applicable to high electron mobility transistor (HEMT) channels with moderate carrier mobilities, has been applied to enhancement-mode (E-mode) and depletion-mode (D-mode) InAlN/AlN/GaN HEMTs with comparable fT at room and cryogenic temperatures. It was found that the speed of the E-mode HEMTs w...
Vibrational modes and their interactions affect numerous physical processes in condensed-matter systems. In the present work, hydrogen vibrations in Se-doped AlSb were investigated with first-principles calculations. Vibrational frequencies were calculated for the longitudinal, transverse, wag (bending), and stretch modes of the Al-H complex. The Al-H stretch mode interacts with a combination m...
