In this paper, several epitaxial variations influencing the two-dimensional electron gas (2DEG) in AlGaN/AlN/GaN heterostructures are investigated. The effects of an n-doped AlGaN barrier and AlN spacer thickness studied by examining sheet density (ns) mobility (µs) 2DEG using ID(VG) C(VG) measurements, 1D Schrödinger-Poisson (1DSP) simulations. Specifically, correlations between resistance, µs...

We obtain new bounds for the solution of variance-gamma (VG) Stein equation that are correct form approximations in terms Wasserstein and Kolmogorov metrics. These hold all parameters values four parameter VG class. As an application we explicit distance error a six moment theorem approximation double Wiener-Itô integrals.

BACKGROUND The Breast Cancer Study Group of the Hellenic Oncology Research Group conducted a phase III trial of single-agent capecitabine versus the vinorelbine/gemcitabine doublet in patients with metastatic breast cancer (MBC) pretreated with anthracyclines and taxanes. The primary objective was to demonstrate superiority of combination treatment in terms of progression-free survival (PFS). ...

Additive genetic variance (VA ) and total genetic variance (VG ) are core concepts in biomedical, evolutionary and production-biology genetics. What determines the large variation in reported VA /VG ratios from line-cross experiments is not well understood. Here we report how the VA /VG ratio, and thus the ratio between narrow and broad sense heritability (h(2) /H(2) ), varies as a function of ...

Complex social behaviour in Hymenoptera has been hypothesized to evolve by co-opting reproductive pathways (the ovarian ground plan hypothesis, OGPH) and gene networks (the reproductive ground plan hypothesis, RGPH). In support of these hypotheses, in eusocial Hymenoptera where there is reproductive division of labour, the yolk precursor protein vitellogenin (Vg) influences the expression of wo...

The "target of rapamycin" (TOR) nutritional signaling pathway and juvenile hormone (JH) regulation of vitellogenesis has been known for a long time. However, the interplay between these two pathways regulating vitellogenin (Vg) expression remains obscure. Here, we first demonstrated the key role of amino acids (AAs) in activation of Vg synthesis and egg development in Nilaparvata lugens using c...

Insect wing is a key evolutionary innovation for insect radiation, but its origins and intermediate forms are absent from the fossil record. To understand the ancestral state of the wing, expression of three key regulatory genes in insect wing development, wingless (wg), vestigial (vg), and apterous (ap) was studied in two basal insects, mayfly and bristletail. These basal insects develop dorsa...

Objective: Papaverine is a topical agent commonly used during microvascular surgery to inhibit undesired vasoconstriction. There is a national shortage of papaverine due to ceased production by the only manufacturer within the United States. Establishment of an alternative vasodilator is critically important. This study aims to assess the experience of a solution of verapamil and nitroglycerin ...

Insulin-stimulated gastric secretion alone, without reference to basal secretion, has been examined in 45 male patients with duodenal ulcer in whom no gastric operation had been performed and in 124 patients following vagotomy for duodenal ulcer. Gastric juice was examined in terms not only of conventional indices, observed volume, titratable acidity and acid output, but also Vg, the volume cor...
