Abstract In this paper, we study and prove the non-asymptotic superlinear convergence rate of Broyden class quasi-Newton algorithms which includes Davidon–Fletcher–Powell (DFP) method Broyden–Fletcher–Goldfarb–Shanno (BFGS) method. The asymptotic these methods has been extensively studied in literature, but their explicit finite–time local is not fully investigated. provide a (non-asymptotic) a...

This work reports record-high three-terminal on-state drain-source breakdown voltage (BVDS) of -735 V in p-channel GaN metal-oxide-semiconductor heterostructure field-effect transistors (MOS-HFETs) with a drain field-plate (DFP). High-k and wide-gap Al2O3 was deposited as the gate oxide surface passivation by using non-vacuum ultrasonic spray pyrolysis deposition (USPD) technique. Good source/d...

Multiple autonomous agents interact over a random communication network to maximize their individual utility functions which depend on the actions of other agents. We consider decentralized best-response with inertia type algorithms in form beliefs about future players based local information, and take that expected utilities computed respect these or continue previous actions. show convergence...

The fatigue crack growth (FCG) behavior of 34CrMo4 steel, a typical material for gas cylinders, has been investigated. Specimens were taken from the base (BM) as well hot-drawn (HD) cylinder and cold-flow (CF) formed along longitudinal transverse directions. FCG tests conducted under different stress ratios materials main purpose this research was to explore influences mechanical thermal proces...

Background Most deaths in thalassemia major (TM) result from cardiac complications due to iron overload. No data are available in literature about possible different changes in cardiac iron in TM patients treated with sequential deferipron-deferoxamine (DFP-DFO) versus deferasirox (DFX). Magnetic Resonance (MR) is the unique non invasive suitable technique to evaluated quantitatively this issue.
