Vertical enhancement-mode InAs nanowire field-effect transistor with 50-nm wrap gate

We present results on fabrication and de characterization of vertical InAs nanowire wrap-gate field-effect transistor arrays with a gate length of 50 nm. The wrap gate is defined by evaporation of 50-nm Cr onto a 10-nm-thick HfO2 gate dielectric, where the gate is also separated from the source contact with a 100-nm SiOx spacer layer. For a drain voltage of 0.5 V, we observe a normalized transcond

Dimension of Countable Intersections of Some Sets Arising in Expansions in Non-Integer Bases

Abstract in Undetermined We consider expansions of real numbers in non-integer bases. These expansions are generated by beta-shifts. We prove that some sets arising in metric number theory have the countable intersection property. This allows us to consider sets of reals that have common properties in a countable number of different (non-integer) bases. Some of the results are new even for integer

Phthalates and Perfluorooctanesulfonic Acid in Human Amniotic Fluid: Temporal Trends and Timing of Amniocentesis in Pregnancy

BACKGROUND: Measures of prenatal environmental exposures are important, and amniotic fluid levels may directly reflect fetal exposures during hypothesized windows of vulnerability. OBJECTIVES: We aimed to detect various phthalate metabolites and perfluorooctanesulfonic acid (PFOS) in human amniotic fluid, to study temporal exposure trends, and to estimate potential associations with gestational we

Fluid-solid transitions in soft-repulsive colloids

We use monodisperse poly(N-isopropylacrylamide) (PNIPAM) microgels as a model system for soft repulsive colloids and study their density dependent structural ordering and phase behaviour using confocal laser scanning microscopy (CLSM). The experiments are carried out at low temperatures, where the particles are in the swollen state and interact via a Hertzian potential, evidenced through a quantit

Ventilated Trombe wall as a passive solar heating and cooling retrofitting approach; a low-tech design for off-grid settlements in semi-arid climates

In the coming years, it is anticipated that if we continue with the same pace of energy consumption, communities will continue to face three major challenges; a mounting increase in energy demands, pollution, and global warming. On a local scale, Egypt is experiencing one of its most serious energy crises in decades. The energy consumed in indoor cooling and heating is the biggest portion of total

Production of pions, kaons and protons in pp collisions at root s=900 GeV with ALICE at the LHC

The production of pi(+), pi(-), K+, K-, p, and (p) over bar at mid-rapidity has been measured in proton-proton collisions at root s = 900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. In addition, time-of-flight information is used to identify hadrons at higher momenta. Finall

Lifestyle Risk Factors for Ischemic Stroke and Transient Ischemic Attack in Young Adults in the Stroke in Young Fabry Patients Study

Background and Purpose-Although many stroke patients are young or middle-aged, risk factor profiles in these age groups are poorly understood. Methods-The Stroke in Young Fabry Patients (sifap1) study prospectively recruited a large multinational European cohort of patients with cerebrovascular events aged 18 to 55 years to establish their prevalence of Fabry disease. In a secondary analysis of pa

Clusters binding to the graphene moire on Ir(111): X-ray photoemission compared to density functional calculations

Our understanding of metal-atom cluster adsorption on graphene on Ir(111) is based on elementary chemical ideas, rehybridization, and buckling, supported by density functional theory (DFT) calculations. We tested the DFT picture by comparing calculated core level spectra to x-ray photoemission spectroscopy (XPS) measurements. For pristine graphene, which forms a gently undulating moire on Ir(111),

Tyrosine kinase inhibition in renal cell carcinoma and gastrointestinal stromal tumours: case reports

Background: Sunitinib malate is approved multinationally for the treatment of metastatic renal cell carcinoma (mRCC) and advanced imatinib-refractory gastrointestinal stromal tumour (GIST). Greater exposure to sunitinib is associated with improved efficacy. Therefore, minimising the impact of adverse events (AEs) on patient quality of life is important to enable patients to achieve optimal exposur

Preventing knee injuries in adolescent female football players - design of a cluster randomized controlled trial [NCT00894595]

Background: Knee injuries in football are common regardless of age, gender or playing level, but adolescent females seem to have the highest risk. The consequences after severe knee injury, for example anterior cruciate ligament (ACL) injury, are well-known, but less is known about knee injury prevention. We have designed a cluster randomized controlled trial (RCT) to evaluate the effect of a warm

Flavonoids – Precipitation Kinetics and Interaction with Surfactant Micelles

Polyphenolic substances, such as flavonoids, attract considerable interest due to their ability to act as antioxidants. The vast majority of studies published deal with the nutritional, biochemical, or chemical structure aspects of these substances while few reports exist on the physico-chemical properties as well as solution behavior of the substances. In this article we report on the precipitati

Organizing disciplinary power in a knowledge organization

This article provides a systematic attempt to analyze the effects of performance appraisals, here conceptualized as tools for executing disciplinary power, and how the agency of employees is shaped. The article demonstrates how agency is enrolled by a broad set of disciplinary technologies aimed at behavior as well as the self, orchestrated in way that effectively short-circuits resistance.

Can a Chiral System Be Built on a Strongly Asymmetric Nucleon Configuration?

The multi-particle-plus-triaxial-rotor (MPR) model calculations were performed for several nuclei in the 100, 130 and 190 mass regions. It was found that chiral geometry can form even for very asymmetric nucleon configurations. However, the near-degeneracy of the partner bands may not be as good as the one observed for symmetric or slightly asymmetric configurations. DOI:10.5506/APhysPolB.44.341

Prevalence of Tibiofemoral Osteoarthritis 15 Years After Nonoperative Treatment of Anterior Cruciate Ligament Injury: A Prospective Cohort Study.

BACKGROUND: The occurrence of osteoarthritis (OA), associated meniscal injuries, meniscectomy, and patient-related measures for patients treated nonoperatively after anterior cruciate ligament (ACL) injuries have not been well described in the literature in terms of natural history. HYPOTHESIS: Patients with ACL injury can achieve a low occurrence of tibiofemoral OA and good knee function when tre
