Vertex correction calculations for an electron gas

A straightforward attempt to estimate the influence of the first vertex correction for a homogeneous electron gas is made. The approximation scheme is also tested on a solvable model of a core electron coupled to an electron gas.(12 refs)

Interferon-γ-induced p27KIP1 binds to and targets MYC for proteasome-mediated degradation.

The Myc oncoprotein is tightly regulated at multiple levels including ubiquitin-mediated protein turnover. We recently demonstrated that inhibition of Cdk2-mediated phosphorylation of Myc at Ser-62 pharmacologically or through interferon (IFN)-γ-induced expression of p27Kip1 (p27) repressed Myc's activity to suppress cellular senescence and differentiation. In this study we identified an additiona

Genetic and epigenetic factors are associated with expression of respiratory chain component NDUFB6 in human skeletal muscle

Insulin resistance and type 2 diabetes are associated with decreased expression of genes that regulate oxidative phosphorylation in skeletal muscle. To determine whether this defect might be inherited or acquired, we investigated the association of genetic, epigenetic, and nongenetic factors with expression of NDUFB6, a component of the respiratory chain that is decreased in muscle from diabetic p

On the importance of hysteresis and heterogeneity in the numerical simulation of unsaturated flow

Soil hydraulic properties in field scale porous media are distributed with large spatial heterogeneity. Thus, detailed understanding of micro-physical properties leading to macro-scale heterogeneity is important for generalizing purposes in modeling. Hysteretic water retention properties greatly affect solute transport under unsaturated condition. In this study, laboratory infiltration experiments

RIFM fragrance ingredient safety assessment, α-Ionone, CAS Registry Number 127-41-3.

The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Repeated dose toxicity was determined to have the most conservative systemic exp

The challenge of achieving target drug concentrations in clinical trials: experience from the Symphony study.

BACKGROUND: The Symphony study compared four immunosuppressant regimens, defined by protocol-specified target drug concentrations. This subanalysis examines actual drug levels and the implications on the interpretation of results. METHODS: De novo renal transplant patients (n=1645) were randomized to receive mycophenolate mofetil (2 g/day) and corticosteroids in combination with standard-dose cycl

Computed tomography measurements of different dimensions of maxillary and frontal sinuses.

We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinus

Uniting Against Autocrats : Opposition Coordination, Turnovers and Democratization by Elections

As counter intuitive as it might sound, autocracy without elections is a rare combination today. Elections do not constitute democracy, but they can promote democratization. This dissertation studies the process of democratization through elections, focusing on the effect of opposition coordination. Several authors have stressed the importance of opposition coordination as an explanation for democ

Chip for wideband digital predistortion RF power amplifier linearisation

The authors present a custom chip for use in digital predistortion linearisation of RF power amplifiers. The chip is mainly implemented with systolic arrays. At maximum clock-rate, 130 MHz, the throughput is 16 Msamples/s with a 5 V supply voltage and power consumption of 1 W. A throughput of 2 Msamples/s is achieved at a 1.2 V supply voltage with 6 mW power consumption
