Doping Incorporation in InAs nanowires characterized by capacitance measurements

Sn and Se doped InAs nanowires are characterized using a capacitance-voltage technique where the threshold voltages of nanowire capacitors with different diameter are determined and analyzed using an improved radial metal-insulator-semiconductor field-effect transistor model. This allows for a separation of doping in the core of the nanowire from the surface charge at the side facets of the nanowi

Climate Change through the lens of intersectionality

Investigations of the interconnectedness of climate change with human societies require profound analysis of relations among humans and between humans and nature, and the integration of insights from various academic fields. An intersectional approach, developed within critical feminist theory, is advantageous. An intersectional analysis of climate change illuminates how different individuals and

Techno-economic assessment of nonfossil ammonia production

The production of nitrogen fertilizers are almost exclusively based on fossil feedstocks such as natural gas and coal. Nitrogen fertilizers are a necessity to maintain the high agricultural production that the world's population currently demands. Ammonia produced from nonfossil-based feedstocks would enable renewable production of ammonia. Renewable feedstocks are one thing, but perhaps even more

Estimation of Soil Base Cation Weathering Rates with the PROFILE Model to Determine Critical Loads of Acidity for Forested Ecosystems in Pennsylvania, USA: Pilot Application of a Potential National Methodology

Base cation weathering (BCw) rate is one of the most influential yet difficult to estimate parameters in the calculation of critical acid loads of nitrogen (N) and sulfur (S) deposition for terrestrial systems. Only the clay correlation-substrate method, a simple empirical model, has been used for estimating BCw rates for forest ecosystems in the conterminous USA and may not be suitable for applic

Genetic and Familial Environmental Influences on the Risk for Drug Abuse: A National Swedish Adoption Study.

CONTEXT: Prior research suggests that drug abuse (DA) is strongly influenced by both genetic and familial environmental factors. No large-scale adoption study has previously attempted to verify and integrate these findings. OBJECTIVE: To determine how genetic and environmental factors contribute to the risk for DA. DESIGN: Follow-up in 9 public databases (1961-2009) of adopted children and their

Large Eddy Simulations of a piloted lean premix jet flame using finite-rate chemistry

A Large Eddy Simulation (LES) model capable of accurately representing finite-rate chemistry effects in turbulent premixed combustion is presented. The LES computations use finite-rate chemistry and implicit LES combustion modelling to simulate an experimentally well-documented lean-premixed jet flame stabilized by a stoichiometric pilot. The validity of the implicit LES assumption is discussed an

On Women's Ambivalence about Mammography Screening: Support in the Decision-Making Process a Potential Role for Health Care Social Workers?

The aim of this article is to reach a deeper understanding of women's decision-making process regarding non-attendance at mammography screenings. The article also discusses the health care social workers' role in providing support to women during this decision. Eighteen qualitative semi-structured interviews were conducted with women who had abstained from mammography screening in Malmö, Sweden. T

Adaptation to Swedish and further development of the 'Consequences of Screening - Breast Cancer' questionnaire: a multimethod study.

Scand J Caring Sci; 2012 Adaptation to Swedish and further development of the 'Consequences of Screening - Breast Cancer' questionnaire: a multimethod study Rationale: Experiencing a false-positive screening mammography can cause considerable psychosocial distress. The Consequences of Screening - Breast Cancer questionnaire (COS-BC parts 1 and 2), recently developed in Denmark, is the only conditi

Evaluation of the ductile - brittle transition temperature in the NESC-I material using small punch testing

Small punch (SP) fracture testing with subsequent SEM fractographic analysis was applied to an A 508 Class 3 reactor pressure vessel(RPV) steel, used originally in the NESC-I spinning cylinder experiment, in order to determine the SP ductile-brittle transition temperature of both the base material and the sub-clad heat affected zone. In addition to the evaluation of the SP transition temperature,

Tomato thymidine kinase-based suicide gene therapy for malignant glioma-an alternative for Herpes Simplex virus-1 thymidine kinase.

Malignant gliomas (MGs) are the most common malignant primary brain tumors with a short life estimate accompanied by a marked reduction in the quality of life. Herpes Simplex virus-1 thymidine kinase ganciclovir (HSV-TK/GCV) system is the best characterized enzyme prodrug therapy in use. However, lipophobicity of GCV and low enzymatic activity of HSV-TK reduce the treatment efficacy. Tomato TK (To

Analyzing Networks of Issue Reports

Completely analyzed and closed issue reports in software development projects, particularly in the development of safety-critical systems, often carry important information about issue-related change locations. These locations may be in the source code, as well as traces to test cases affected by the issue, and related design and requirements documents. In order to help developers analyze new issu

Numerically Stable Optimization of Polynomial Solvers for Minimal Problems

Numerous geometric problems in computer vision involve the solu- tion of systems of polynomial equations. This is particularly true for so called minimal problems, but also for finding stationary points for overdetermined prob- lems. The state-of-the-art is based on the use of numerical linear algebra on the large but sparse coefficient matrix that represents the original equations multi- plied wi

Experience-dependent plasticity of white-matter microstructure extends into old age

Experience-dependent alterations in the human brain's white-matter microstructure occur in early adulthood, but it is unknown whether such plasticity extends throughout life. We used cognitive training, diffusion-tensor imaging (DTI), and structural MRI to investigate plasticity of the white-matter tracts that connect the left and right hemisphere of the frontal lobes. Over a period of about 180 d

Inclusive deep inelastic scattering at high Q(2) with longitudinally polarised lepton beams at HERA

Inclusive e(+/-)p single and double differential cross sections for neutral and charged current deep inelastic scattering processes are measured with the H1 detector at HERA. The data were taken at a centre-of-mass energy of root s = 319 GeV with a total integrated luminosity of 333.7 pb(-1) shared between two lepton beam charges and two longitudinal lepton polarisation modes. The differential cro

Nano-engineered living bacterial motors for active microfluidic mixing.

Active micromixers with rotating elements are attractive microfluidic actuators in many applications because of their mixing ability at a short distance. However, miniaturising the impeller design poses technical challenges including the fabrication and driving means. As a possible solution inspired by macro magnetic bar-stirrers, this study proposes the use of tethered, rotating bacteria as mixin

Outwards migration for planets in stellar irradiated 3D discs

For the very first time we present 3D simulations of planets embedded in stellar irradiated discs. It is well known that thermal effects could reverse the direction of planetary migration from inwards to outwards, potentially saving planets in the inner, optically thick parts of the protoplanetary disc. When considering stellar irradiation in addition to viscous friction as a source of heating, th
