We propose a method for the optimal time-controlled generation of entangled itinerant particles, using on-demand sources in a conductor in the quantum Hall regime. This entanglement pump is realized by applying periodic, tailored voltage pulses to pairs of quantum dots or quantum point contacts. We show that the pump can produce orbital Bell pairs of both electrons and holes at the optimal rate of
Abstract in UndeterminedWe bring together three decades of research from a boreal catchment to facilitate an improved mechanistic understanding of surface water dissolved organic carbon (DOC) regulation across multiple scales. The Krycklan Catchment Study encompasses 15 monitored nested research catchments, ranging from 3 to 6900 ha in size, as well as a set of monitored transects of forested and
The objective of this study is to clarify use of the term mastitis in empirical studies of lactational mastitis. Eighteen articles published between 1998 and 2008 were critically analyzed, and a concept clarification of the term mastitis was carried out. Four articles suggested that mastitis was an infection, 4 made no mention of the etiology of symptoms, and 10 articles described mastitis as an i
We describe a general computational method for designing proteins that self-assemble to a desired symmetric architecture. Protein building blocks are docked together symmetrically to identify complementary packing arrangements, and low-energy protein-protein interfaces are then designed between the building blocks in order to drive self-assembly. We used trimeric protein building blocks to design
A closely-packed ultrawideband (UWB) multiple- input multiple-output (MIMO)/diversity antenna (of two elements) with a size of 25 mm by 40 mm is proposed for USB dongle applications. Wideband isolation can be achieved through the different patterns and polarizations of the two antenna elements. Moreover, the slot that is formed between the monopole and the ground plane of the half slot antenna is
Background. Uraemia increases oxidative stress, plasma titres of antibodies recognizing oxidized low-density lipoprotein (oxLDL) and development of atherosclerosis. Immunization with oxLDL prevents classical, non-uraemic atherosclerosis. We have investigated whether immunization with oxLDL might also prevent uraemia-induced atherosclerosis in apolipoprotein E knockout (apoE-/-) mice. Methods. ApoE
The physical environment of supported-housing facilities (SHF) for people with severe mental illness has mainly been investigated in terms of neighborhood quality and community integration, largely neglecting the design of housing attributes. This study investigated whether SHFs with high and low levels of physical-environment quality differed in their support of users' (residents and staff) needs
The particle formation and growth events observed at a semirural background site in Denmark were analyzed based on particle number size distribution data collected during the period from February 2005 to December 2010. The new particle formation (NPF) events have been classified visually in detail according to 3D daily plots in combination with an automatic routine. A clear seasonal variation was
Particles of RuSeMo and RuSnMo have been produced by ball milling; they present catalytic activity towards the oxygen reduction reaction (ORR) in acid media. A Tafel slope close to 120 mV/dec was found for both materials. Their morphology was first characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM and TEM images reveal particles in the sub-micromet
Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. To address this challenge, a novel, polymer-based neural probe, with protrusions tailored to the
In this study, a three-phase hollow fiber liquid-phase microextraction (HF-LPME) method combined with liquid chromatography-mass spectrometry was developed for direct determination of four non-steroidal anti-inflammatory drugs (ketoprofen, naproxen, diclofenac and ibuprofen) in sewage sludge. The drugs were extracted from non-spiked and spiked slurry samples with different amounts of sludge into a
Chronic lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) are two lung diseases that are continuously increasing worldwide. Despite extensively research to find curative treatment, no so such therapy exists today. New hypothesis suggests that an aberrant chronic wound healing process takes place which involves both the classical inflammation and more chronic changes of
Upper limits on direct photon production were determined as a function of the transverse momentum for 0.7 < pT ≤ 3.2 GeV/c with the WA98 experiment in p + C and p + Pb collisions at . The results are compared to direct photon measurements in Pb + Pb collisions at by WA98. Implications for a possible thermal direct photon contribution are discussed.
Popular Abstract in Swedish Avhandlingens övergripande syfte är att kritiskt studera interorganisatoriska samverkansprocesser och sammanhängande konsekvenser, med ett särskilt fokus på rättens och maktens betydelse. Analysen av det empiriska materialet, som speglar samverkan i en kontext av barnahus på sex orter i Sverige (samverkan under ett tak kring utredningar av misstänkta brott mot barn), The overarching objective of the dissertation is to study inter-organisational collaboration processes and their associated consequences in a critical manner, with particular emphasis on the importance of law and power. The analysis of the empirical material, reflecting collaboration in the context of Barnahus on six locations in Sweden (collaboration under one roof regarding investigations of s
Commercial potato protein concentrate (PPC) was investigated as a source of thermoformed bio-based plastic film. Pressing temperatures of 100 to 190 degrees C with 15 to 25% glycerol were used to form PPC films. The shape of the tensile stress-strain curve in thermoformed PPC was controlled by glycerol level and was independent of processing temperature. Tensile testing revealed that elongation at
OBJECTIVE: To estimate the incremental cost-effectiveness of infliximab versus conventional combination treatment over 21 months in patients with methotrexate-refractory early rheumatoid arthritis. METHODS: In this multicentre, two-arm, parallel, randomised, active-controlled, open-label trial, rheumatoid arthritis patients with <1 year symptom duration were recruited from 15 rheumatology clini
An exploratory study of a train evacuation inside a tunnel was performed in order to study the effects of different train exit configurations on the flow rate of people through the exit. A total of 84 participants in the ages 18–40 years took part in the experiment, which was carried out on two separate days and involved 18 evacuation scenarios. The statistical analysis of the experiment demonstra
Context: Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. Objective: To critically review the recent data on the management of NMIBC to arrive at a general consensus. Evidence acquisition: A detailed Med
The structuring of quantitative genetic variation can have a significant impact on the adaptive potential and long-term viability of species in changing landscapes. The present study of the grass Briza media investigated the relationships between patterns of heritable variation in phenotypic characters and descriptors of landscape structure, land-use history and local habitat conditions in a lands
