The calculation of material gain and performance characteristics compound III–V semiconductor quantum well (QW) lasers has been developed, incorporating various approximations for the band structure. As accuracy sophistication structure are increased, computational time mathematical complexity rise accordingly. modeling QW is examined to determine criteria accurate use a parabolic approximation...
PURPOSE Multiple cancers harbor genetic aberrations that impact AKT signaling. MK-2206 is a potent pan-AKT inhibitor with a maximum tolerated dose (MTD) previously established at 60 mg on alternate days (QOD). Due to a long half-life (60-80 hours), a weekly (QW) MK-2206 schedule was pursued to compare intermittent QW and continuous QOD dosing. EXPERIMENTAL DESIGN Patients with advanced cancer...
OBJECTIVES The purpose of this study was to determine the pathologic basis of Q-wave (QW) and non-Q-wave (NQW) myocardial infarction (MI). BACKGROUND The QW/NQW distinction remains in wide clinical use but the meaning of the difference remains controversial. We hypothesized that measurement of total MI size and transmural extent by late gadolinium enhancement cardiovascular magnetic resonance...
The hybrid structure of GaAs/GaAsSb quantum well (QW)/InAs quantum dots solar cells (QDSCs) is analyzed using power-dependent and temperature-dependent photoluminescence. We demonstrate that placing the GaAsSb QW beneath the QDs forms type-II characteristics that initiate at 12% Sb composition. Current density-voltage measurements demonstrate a decrease in power efficiency with increasing Sb co...
OBJECTIVE In the Diabetes Therapy Utilization: Researching Changes in A1C, Weight and Other Factors Through Intervention with Exenatide Once Weekly (DURATION-1) study, the safety and efficacy of 30 weeks of treatment with the glucagon-like peptide-1 receptor agonist exenatide once weekly (exenatide QW; 2 mg) was compared with exenatide BID in 295 patients with type 2 diabetes. We now report the...
where π denotes a prior distribution on w, which we set as zero-mean Gaussian, π(w) ∝ exp(− 12 ||w|| ). We choose Qw as a Gaussian centered at αw, Qw(w̄) ∝ exp(− 12 ||w̄ − αw|| ). Then, the KL divergence between Qw and π is just α||w||/2. Analyzing the sample risk L(Qw, S) can be done for each training instance due to i.i.d. sampling. We denote by Ȳ i the predicted output for x with respect to w̄....
In this study, we present the optical properties of nonpolar GaN/(Al,Ga)N single quantum wells (QWs) grown on either aor m-plane GaN templates for Al contents set below 15%. In order to reduce the density of extended defects, the templates have been processed using the epitaxial lateral overgrowth technique. As expected for polarization-free heterostructures, the larger the QW width for a given...
Time-resolved cathodoluminescence (CL) techniques have been employed to examine the optical properties and kinetics of carrier relaxation in a InGaN/GaN single quantum well (QW) sample. CL images of the QW sample revealed a spotty cellular pattern indicative of local In compositional variations, which induce local potential fluctuations and result in a strong lateral excitonic localization at I...
