InGaAs/AlGaAs QW vertical-cavity surfaceemitting lasers (VCSELs) have been studied for optical interconnection because of their possibility of ultra low power c~nsumption.~ Much lower threshold VCSELs can be expected by introducing the n-type modulation doping technique reported here. From the above data, we can estimate the threshold current of a single QW VCSEL having 3 pmcore fabricated by n...

Editor’s note: Exenatide once weekly (QW), which was recently approved for patients with type 2 diabetes, has great potential as a new diabetes therapy in the primary care setting. This article, and the commentary that precedes it (p. 92), offer an overview of this new therapeutic tool and important insights about its clinical utility. In the interest of transparency, however, we want to point ...

BACKGROUND The EVIDENCE (EVidence of Interferon Dose-response: European North American Comparative Efficacy) study was an international, randomized, open-label, assessor-blinded, parallel-group study assessing the efficacy and tolerability of interferon (IFN) beta-1a, 44 mcg subcutaneously (sc) three times weekly (tiw), and IFN beta-1a, 30 mcg intramuscularly (im) once weekly (qw), in patients ...

Large negative thermal quenching (NTQ) of the yellow luminescence (YL) for a temperature increase from 5 to 300 K is observed in non-polar InGaN/GaN quantum well (QW) samples due migration carriers InGaN QW layers GaN barrier first time. Such an unusual phenomenon happens only when are optically excited inside layers, providing solid evidence occurrence transfer photoexcited layers. A simple mo...

BACKGROUND C.E.R.A. (Continuous Erythropoietin Receptor Activator) is an innovative agent with unique erythropoietin receptor activity and prolonged half-life. This study evaluated C.E.R.A. once weekly (QW) or once every 3 weeks (Q3W) in patients with anemia and advanced non-small cell lung cancer (NSCLC) receiving chemotherapy. METHODS In this Phase II, randomized, open-label, multicenter, d...

BACKGROUND The once-weekly (QW) formulation of the glucagon-like peptide-1 receptor agonist exenatide has been demonstrated to improve A1C, fasting plasma glucose (FPG), body weight, serum lipid profiles, and blood pressure in patients with type 2 diabetes through 52 weeks of treatment. In this report, we describe the 2-year results of the open-label, open-ended extension to the DURATION-1 tria...

using qcd factorization for the hadronic matrix elements, we show that existing data, inparticular the branching ratios br ( b →j/ψk) and br ( b →j/ψπ), can be accounted for in this approach.we analyze the decay b j /k( ) within the framework of qcd factorization. the calculation of therelevant hard-scattering kernels for twist-2 and twist-3 is completed. we calculate this decay in a special...

The triple factorization of a group $G$ has been studied recently showing that $G=ABA$ for some proper subgroups $A$ and $B$ of $G$, the definition of rank-two geometry and rank-two coset geometry which is closely related to the triple factorization was defined and calculated for abelian groups. In this paper we study two infinite classes of non-abelian finite groups $D_{2n}$ and $PSL(2,2^{n})$...

In this paper, several exact expressions for the mean heat flux at wall (qw) compressible turbulent channel flows are derived by using internal energy equation or total equation. Two different routes, including FIK method and RD method, can be applied. The direct numerical simulation data of Reynolds Mach numbers verify correctness formulas. Discussions related to equations, routes carried out,...

In this paper, the 2-state decomposed-type quantum walk (DQW) on a line is introduced as an extension of (QW). The time evolution DQW defined with two different matrices, one assigned to real component, and other imaginary component state. Unlike ordinary QWs, localization spreading phenomenon can coincide in DQWs. Additionally, always be converted corresponding 4-state QW identical probability...
