The Multi-Grid detector technology has evolved from the proof-of-principle and characterisation stages. Here we report on the performance of the Multi-Grid detector, the MG.CNCS prototype, which has been installed and tested at the Cold Neutron Chopper Spectrometer, CNCS at SNS. This has allowed a side-by-side comparison to the performance of 3He detectors on an operational instrument. The demonst

Metal nanoparticles (NPs), in particular gold NPs, are often used in the fabrication process of semiconductor nanowires. Besides being able to induce the 1D crystallization of new material, it is highly beneficial if the NPs can be used to dictate the position and diameter of the final nanowire structure. To achieve well-defined NP arrays of varying diameter and pitch distances for nanowire growth

InGaAs nanowires is one of the promising material systems of replacing silicon in future CMOS transistors, due to its high electron mobility in combination with the excellent electrostatic control from the tri-gate geometry. In this article, we report on gated Hall measurements on single and multiple In0.85Ga0.15As nanowires, selectively grown in a Hall bridge geometry with nanowire widths down to

III-V semiconductor nanowires are a platform for next-generation photovoltaics. An interesting research direction is to embed a nanowire array in a transparent polymer, either to act as a stand-alone flexible solar cell, or to be stacked on top of a conventional Si bottom cell to create a tandem structure. To optimize the tandem cell performance, high energy photons should be absorbed in the nanow

Ett reflexivt ledarskap handlar om att överväga vad vi menar med ledarskap, vad det kan göra och inte göra, när det kan fungera och när det inte är bästa alternativet. Författarnas ambition är att uppmuntra chefer och andra att tänka både bredare och djupare om hur man bäst samordnar arbete i moderna organisationer. I detta ingår att även lyfta fram och diskutera alternativen till ledarskap.Boken

The six planets of the Kepler-11 system are the archetypal example of a population of surprisingly low-density transiting planets revealed by the Kepler mission. We have determined the fundamental parameters and chemical composition of the Kepler-11 host star to unprecedented precision using an extremely high-quality spectrum from Keck-HIRES (R ≃ 67,000, S/N per pixel at 600 nm). Contrary to previ

The incidence of cancer is increasing worldwide and metastatic disease, through the spread of circulating tumor cells (CTCs), is responsible for the majority of the cancer deaths. Accurate monitoring of CTC levels in blood provides clinical information supporting therapeutic decision making, and improved methods for CTC enumeration are asked for. Microfluidics has been extensively used for this pu

BACKGROUND: Neuromuscular diseases (NMD) can affect the ability to be employed and to work, but there is limited knowledge of individuals' own perspectives of factors that are important for their vocational situation. OBJECTIVE: To explore the vocational situation among people with NMD that are employed, and to describe their experiences of how their disability, personal and environmental factors

OBJECTIVES: Plant-derived natural substances, such as capsaicin, with potent antiproliferative activity against cancer cells in vitro are considered to be promising nutraceuticals in anticancer therapy. Nevertheless, the limited systemic bioavailability of phytochemicals may raise questions regarding the physiological relevance of their phytochemical effects in vivo. Thus, the search for novel phy

PURPOSE: To define the radiographic prevalence of scaphotrapeziotrapezoid (STT) osteoarthrosis (OA) in a cohort of patients presenting to a hand surgeon for any complaint. The secondary purpose was to evaluate coexisting thumb carpometacarpal (CMC) joint OA.METHODS: Seven hundred radiographs were evaluated for presence and degree of STT and thumb CMC arthritic changes in consecutive patients prese

Class 3 semaphorins were discovered as a family of axon guidance molecules, but are now known to be involved in diverse biologic processes. In this study, we investigated the anti-angiogenic potential of SEMA3E and SEMA3F (SEMA3E&F) in infantile hemangioma (IH). IH is a common vascular tumor that involves both vasculogenesis and angiogenesis. Our lab has identified and isolated hemangioma stem

BACKGROUND: Experiencing work-life balance is considered a health promoting resource. To counter-balance the negative development of teachers' work situation, salutogenic resources need to be examined among teachers. OBJECTIVE: To examine resources related to teachers' experience of their work-life balance. METHODS: Using a cross-sectional design, a questionnaire was distributed to 455 teachers in

Objectives: To investigate the long-term functional outcomes and complications after continent cutaneous diversion with the Lundiana pouch. Patients and Methods: Complications, re-operations, renal function, and continence were ascertained from patient charts. Outcome variables were validated by a second and independent review of the patient files. Results: A complication of Clavien-Dindo grade ≥I

Deficient production of anti-viral interferons (IFNs) may be involved in causing viral-induced asthma exacerbations. Hence, drugs inducing lung IFN production would be warranted. Azithromycin may reduce asthma exacerbations but its modus operandi is unknown. Here, we investigated if azithromycin induces IFNβ expression in vitro in rhinovirus-infected bronchial epithelial cells from asthmatic donor

Virtually all animal cells express heparan sulfate proteoglycans on the cell surface and in the extracellular matrix. Syndecans are a major group of transmembrane proteoglycans functioning as receptors that mediate signal transmission from the extracellular microenvironment to the cell. Their heparan sulfate chains, due to their vast structural diversity, interact with a wide array of ligands incl
