GaN-based light emitting diodes using p-type trench structure for improving internal quantum efficiency Appl.

A young Russian man presented with increasing shortness of breath and signs of worsening aortic regurgitation. A diagnosis of infective endocarditis was made before emergency valve replacement. The infective cause was not discovered by routine culture but was suggested by electron microscopy and confirmed by serology and PCR testing.

Subduction systems are vitally important to plate tectonics and mantle convection, but questions remain about many aspects of subduction dynamics, particularly the nature of sub-slab mantle flow. Observations of seismic anisotropy can shed light on the pattern of mantle flow in subduction systems, but major uncertainties remain regarding the interpretation of sub-slab anisotropy. Here, we prese...

The case of a 44 year old woman with infective endocarditis due to Bartonella quintana, an organism long recognised to cause a condition known as trench fever, is reported. This case illustrates the lengthy differential diagnosis of "culture negative" endocarditis. In addition the presence of serological cross reactivity of Bartonella spp and Chlamydia spp demonstrates the potential for misdiag...

Analysis of subsurface stormflow from 147 storms at the 20 m long trench in the Panola Mountain Research Watershed by Tromp-van Meerveld and McDonnell (2006a) showed that there was a distinct 55 mm precipitation threshold for significant subsurface stormflow production. This second paper in the series investigates the processes responsible for this threshold response. We installed a dense spati...

Presented here is the first detailed geochemical data set on the U/Th series Th, Pa, AC, and Pb isotopes and artificial fallout radionuclides (90Sr, 137Cs and Pu isotopes), and some trace elements (V, Zn, Cd, Cu, Mn, and Ni ) in two water , columns of the Jap;an and Bonin trenches down to the bottom depths of 7585 m and 9750 m, respectively. Hydrographic properties such as tlemperature, salinit...

Presented in this paper are the characteristics of the first Trench MOS Schottky Diode released to manufacturing by International Rectifier. The optimized Silicon structure enables 15% VF reduction and a factor 4 of leakage suppression compared to a benchmark conventional planar device of the same voltage class. After reviewing the key features of Silicon design, the results of an in-circuit te...

Based on the overlap integral of electromagnetic fields in neighboring cores, a calculating method is proposed for obtaining the coupling coefficient between two adjacent trench-assisted non-identical cores. And a kind of heterogeneous trench-assisted multi-core fiber (Hetero-TA-MCF) with 12 cores is proposed to achieve large effective area (A(eff)) and high density of cores. As bending radius ...

This paper reports a high-throughput, label-free technique to visualize individual carbon nanotubes (CNTs) on a silicon wafer using a conventional optical microscope. We show that individual CNTs can locally enhance the rate of vapor-phase HF etching of SiO2 to produce a SiO2 trench that is several to several tens of nanometers in depth. The trench is visible under an optical microscope due to ...

We demonstrate that great earthquakes occur predominantly in regions with a strongly negative trench-parallel gravity anomaly (TPGA), whereas regions with strongly positive TPGA are relatively aseismic. These observations suggest that, over time scales up to at least 1 million years, spatial variations of seismogenic behavior within a given subduction zone are stationary and linked to the geolo...
