There is a need for isolated current sources for use in selected bio- impedance measurement circuits. The requirement for good isolation is particularly important in medical settings because of safety concerns. A new circuit ...

Band gap variations in thin film structures, across grain boundaries, and in embedded nanoparticles are of increasing interest in the materials science community. As many common experimental techniques for measuring band ...

Thermoelectric application of half-Heusler compounds suffers from their fairly high thermal conductivities. Insight into how effective various scattering mechanisms are in reducing the thermal conductivity of fabricated ...

On 6 December 2002, during winter darkness, an extraordinary event occurred in the sky, as viewed from Longyearbyen (78° N, 15° E), Svalbard, Norway. At 07:30 UT the southeast sky was surprisingly lit up in a deep red ...

The optical band gap of ZnO has been measured as a function of temperature using Electron Energy-Loss Spectroscopy (EELS) in a (Scanning) Transmission Electron Microscope ((S)TEM) from approximately 100 K up towards 1000 K. ...

Diffusion of lithium (Li) in uniformly gallium (Ga)-doped monocrystalline bulk Zinc Oxide (ZnO) is studied over a wide temperature range (500 − 1150◦C) and is demonstrated to be dictated by the distribution of Ga. Below ...

Based on three winters of observational data, we present those ionosphere parameters deemed most critical to realistic space weather ionosphere and thermosphere representation and prediction, in regions impacted by variability ...

Background Patients with large, locally advanced cervical cancers (LACC) are challenging to treat. The purpose of this work is to use 18F-FDG PET as planning basis for a short-course simultaneous integrated ...

Dark matter in the cosmological concordance model is parametrized by a single number, describing the covariantly conserved energy density of a nonrelativistic fluid. Here we test this assumption in a model-independent and ...
