Cation vacancies like V-Ga, V-Al and their complexes with oxygen are predicted to be abundant in III-nitrides and to play an important role in nonradiative recombination. Appearing in triple or double negatively charged states, they are not paramagnetic and have not so far been detected by magnetic resonance even under illumination. In this Brief Report, we demonstrate an efficient way to make cat

Computational models of Achilles tendons can help understanding how healthy tendons are affected by repetitive loading and how the different tissue constituents contribute to the tendon's biomechanical response. However, available models of Achilles tendon are limited in their description of the hierarchical multi-structural composition of the tissue. This study hypothesised that a poroviscoelasti

Previous studies have revealed that wearers had low skin temperatures and cold and pain sensations in the feet, when using sleeping bags under defined comfort and limit temperatures. To improve wearers’ local thermal comfort in the feet, a novel heating sleeping bag (i.e., MARHT) was developed by embedding two heating pads into the traditional sleeping bag (i.e., MARCON) in this region. Seven fema

Excited-state proton transfer has been hypothesized as a mechanism for UV energy dissipation in eumelanin skin pigments. By using time resolved fluorescence spectroscopy, we show that the previously proposed, but unresolved, excited-state intramolecular proton transfer (ESIPT) of the eumelanin building block 5,6-dihydroxyindole-2-carboxylic acid (DHICA) occurs with a time constant of 300 fs in aqu

Modelers seeking to help inform decisions about insurance (public or private) coverage of the cost of pharmaceuticals or other health care interventions face various methodological challenges. In this review, which is not meant to be comprehensive, we cover those that in our experience are most vexing. The biggest challenge is getting decision makers to trust the model. This is a major problem bec

The superfamily of cyclic nucleotide phosphodiesterases is comprised of 11 gene families. By hydrolyzing cAMP and cGMP, PDEs are major determinants in the regulation of intracellular concentrations of cyclic nucleotides and cyclic nucleotide-dependent signaling pathways. Two PDE3 subfamilies, PDE3A and PDE3B, have been described. PDE3A and PDE3B hydrolyze cAMP and cGMP with high affinity in a mutu

Haemophilus influenzae serotype f (Hif) is an etiologic agent of bacterial invasive disease. Here, we report the first annotated genome sequence of the Hif strain KR494, which was isolated from a patient suffering from sepsis and necrotizing myositis. The genome sequence will increase the understanding of Hif pathogenesis.

Abstract in Undetermined There has been an increasing interest in applying GIS into health and healthcare research in recent years.4,5 However, this increasing interest has not yet been gauged. In order to address this, the current study was performed to examine the crude number and the annual rate of papers with ‘Geographic Information Systems’ among their MeSH Terms in PubMed (a free database wh

We present azimuthal anisotropy measurements in Au+Au and Cu+Cu collisions at and 200 GeV. Comparison between reaction plane and cumulant v2 measurements in Au+Au collisions at GeV shows that non-flow contributions, originating mainly from jets, influence the extracted v2 for pT 3.5 GeV/c. Number of constituent quark (NCQ) scaling of v2, when studied as a function of transverse kinetic energy KET,

Objective To describe the clinical history and ultrasound findings in women with ovarian Sertoli cell, Sertoli-Leydig cell and Leydig cell tumors. Methods Women with a histological diagnosis of Sertoli cell tumor, Sertoli-Leydig cell tumor or Leydig cell tumor who bad undergone preoperative ultrasound examination were identified from the databases of each of three participating ultrasound centers.

The size of the anisotropic domains in a lyotropic liquid crystal is estimated using a new protocol for diffusion NMR. Echo attenuation decays are recorded for different durations of the displacement-encoding gradient pulses, while keeping the effective diffusion time and the range of the wave vectors constant. Deviations between the sets of data appear if there are non-Gaussian diffusion processe
