Temperature dependent pulsed and ramped substrate bias measurements are used to develop a detailed understanding of the vertical carrier transport in the buffer layers in a carbon doped GaN power heterojunction field effect transistor. Carbon doped GaN and multiple layers of AlGaN alloy are used in these devices to deliver an insulating and strain relieved buffer with high breakdown voltage cap...

During April-May 2011 two cruises (M84/3, RV Meteor, Istambul-Vigo, and EF11, RV Urania, Bari –La Spezia) overdetermined the CO system in the MedSea for the first time. The internal consistency analysis for pH, alkalinity and total inorganic carbon confirmed the use of CO2 constants from Mehrbach et al. (1973) [1] and others [2] and [3]. This analysis reveals some insights about the peculiar ph...

A highly sensitivefluorometric method for the assayof total alkaline phosphataseand the detection of its components is described. The commercially available substrate naphthyl AS-MX phosphate, combined in 1 M 2-amino-2-methyl-1-propanol buffer, pH 9.8, is cleaved to the highly fluorescent naphthol AS-MX. Fluorometry requires filters passing405 m primary and 505 mi. secondary.As little as 20 1d....

Human von Willebrand factor (vWF) mediates platelet adhesion and thrombus formation under high shear stress conditions; moreover, it binds and stabilizes procoagulant factor VIII in circulating blood. Quantitative and qualitative vWF abnormalities lead to a congenital bleeding disorder: von Willebrand disease (vWD). Mature vWF circulates in plasma as a series of multimers ranging in size from 4...

This paper investigates the kinetics of buffer trapping in GaN-based normally-off high-voltage transistors. The analysis was carried out on transfer-length method (TLM) structures. By means a custom setup, (i) we investigated and de-trapping processes induced by large vertical bias identified different mechanisms, responsible for storage negative positive charge buffer. (ii) temperature-depende...

Scientific discoveries are increasingly dependent upon the analysis of large volumes of data from observations and simulations of complex phenomena. Scientists compose the complex analyses as workflows and execute them on largescale HPC systems. The workflow structures are in contrast with monolithic single simulations that have often been the primary use case on HPC systems. Simultaneously, ne...
