Epitaxial growth and surface studies of the Half Heusler compound NiTiSn (001)

The Half Heuslers are currently an attractive family of compounds for high temperature thermoelectrics research, and recently, there has been renewed interest since some of these compounds are proposed to be topological insulators. NiTiSn belongs to the family of 18 valence electron Half Heuslers that are predicted to be semiconducting, despite being composed entirely of metallic elements. The gro

Degenerate p-doping of InP nanowires for large area tunnel diodes

We have investigated p-doping of InP nanowires using diethyl zinc. Two-terminal devices showed non-linear source-drain characteristics and p-type gate dependence. Electron beam induced current measurements were employed to determine minority carrier diffusion lengths. We used large-area tunnel diodes to demonstrate degenerate doping, showing peak current densities of up to 0.11 A/cm(2) and room te

Some a priori estimates of solutions to the Maxwell equations

In this paper we present a collection of a priori estimates of the electromagnetic field scattered by a general bounded domain. The constitutive relations of the scatterer are in general anisotropic. Surface averages are investigated and several results on the decay of these averages are presented. The norm of the exterior Calderón operator for a sphere is investigated and depicted as a function o

Measurement of four-jet differential cross sections in root s=8 TeV proton-proton collisions using the ATLAS detector

Differential cross sections for the production of at least four jets have been measured in proton-proton collisions at root s = 8 TeV at the Large Hadron Collider using the ATLAS detector. Events are selected if the four anti-k(t) R = 0.4 jets with the largest transverse momentum (p(T)) within the rapidity range vertical bar y vertical bar < 2 : 8 are well separated (Delta R-4j(min) > 0.65), all h

OARSI Clinical Trials Recommendations: Design and conduct of clinical trials of surgical interventions for osteoarthritis.

To highlight methodological challenges in the design and conduct of randomized trials of surgical interventions and to propose strategies for addressing these challenges. This paper focuses on three broad areas: enrollment; intervention; and assessment including implications for analysis. For each challenge raised in the paper, we propose potential solutions. Enrollment poses challenges in maintai

Two common genetic variants near nuclear encoded OXPHOS genes are associated with insulin secretion in vivo.

Context Mitochondrial ATP production is important in the regulation of glucose-stimulated insulin secretion. Genetic factors may modulate the capacity of the β-cells to secrete insulin and thereby contribute to the risk of type 2 diabetes. OBJECTIVE: The aim of this study was to identify genetic loci in or adjacent to nuclear encoded genes of the oxidative phosphorylation (OXPHOS) pathway that are

Swirl switching in turbulent flow through 90 degrees pipe bends

Turbulent flow through 90 degrees pipe bends, for four different curvatures, has been investigated using large eddy simulations. In particular, the origin of the so-called swirl switching phenomenon, which is a large scale oscillation of the flow after the bend, has been studied for different bend curvature ratios. A classification of the phenomenon into a high and a low frequency switching, with

Performing embodied identity in virtual worlds

Embodied identity, that is, who we are as a result of our interactions with the world around us with and through our bodies, is increasingly challenged in online environments where identity performances are seemingly untethered from the user's body that is sitting at the computer. Even though disembodiment has been severely criticized in the literature, most conceptualizations of the role of users

Transglutaminase Iga Antibodies in A Celiac Disease Mass Screening and the Role of Hla-Dq Genotyping and Endomysial Antibodies in Sequential Testing.

OBJECTIVES:: To evaluate hypothetical screening strategies in a Swedish celiac disease (CD) mass screening. PATIENTS AND METHODS:: Out of 10041 Swedish sixth-graders born in 1993 invited to a population-based CD mass screening, 7208 participated. Anti-tissue-transglutaminase (tTG) IgA were analyzed in all children and total serum IgA (s-IgA) in 7161 children. Additional analyses of tTG-IgG, endomy

Risk Factors for Nursing Home Placement in Alzheimer's Disease: A Longitudinal Study of Cognition, ADL, Service Utilization, and Cholinesterase Inhibitor Treatment.

Purpose of the Study: To identify risk factors for early nursing home placement (NHP) in Alzheimer's disease (AD), focusing on the impact of longitudinal change in cognition, activities of daily living (ADL), service utilization, and cholinesterase inhibitor treatment (ChEI). DESIGN AND METHODS: In an open, 3-year, prospective, multicenter study in a routine clinical setting, 880 AD patients were

Child and adult witnesses: the effect of repetition and invitation-probes on free recall and metamemory realism

Witnesses' event recall and the realism in their evaluation of the correctness of their recall are of great importance in forensic processes. These issues were investigated in the present study by use of calibration methodology. More specifically, we analyzed the effects of two recalls of the same event (repetition) and of probes (non-informative follow-up questions at recall) on 9-11 year-old chi

The Economics of Sustainable Land Management Practices in the Ethiopian Highlands

This article uses data from household- and plot-level surveys conducted in the highlands of the Tigray and Amhara regions of Ethiopia. We examine the contribution of sustainable land management (SLM) practices to net value of agricultural production in areas with low vs. high agricultural potential. A combination of parametric and non-parametric estimation techniques is used to check result robust
