We report on the fabrication and characterization of radial tunnel diodes based on InP(n+)/InGaAs(p+) core-shell nanowires, where the effect of Zn-dopant precursor flow on the electrical properties of the devices is evaluated. Selective and local etching of the InGaAs shell is employed to access the nanowire core in the contact process. Devices with an n+-p doping profile show normal diode rectifi
Mergers give acquirers control over the assets of the merged entity and give sellers control over financial assets. We propose a cross-border merger model with home biased financially constrained owners in which the subsequent investments of the buyer and the seller can be determined. We show that policies blocking foreign acquisitions to protect the domestic industry can be counterproductive. For
Background: Up to date data on incidence, mortality, and case-fatality for stroke are important for setting the agenda for prevention and healthcare. Aims and/or hypothesis: We aim to update the most current incidence and mortality data on stroke available by country, and to expand the scope to case-fatality and explore how registry data might be complementary. Methods: Data were compiled using tw
This paper assesses the potential changes in the demand for forest-based biomass for various energy purposes in Sweden in 2030 and 2050, respectively. The assessment is based on a review of scenarios and predictions of how the Swedish energy system may develop, taking into account techno-economical conditions. It includes potential changes in district heating, electricity production in combined he
Aim: The aim of this study was to evaluate the effect of spouses' involvement in older patients' care trajectories, using case management as intervention in total hip replacement through fast-track programmes. Background: Patients need their spouses to be involved in their fast-track programmes and this involvement is often associated with improvements in patient outcomes. However, the effect of s
We analyze the contents of print ads in the motion picture industry (e.g., number of reviews quoted in the ad, the presence of a top reviewer, size of the ad, star, director, etc.). We find that external validation (a recommendation by a top reviewer) is more important to revenues than the informative content of the ad.
Objective: This study explores the effect of voice quality and competing speaker/-s on children’s performance in a passage comprehension task. Furthermore, it explores the interaction between passage comprehension and cognitive functioning. Methods: Forty-nine children (27 girls and 22 boys) with normal hearing (aged 7–12 years) participated. Passage comprehension was tested in six different liste
Purpose: To investigate the cerebrospinal fluid (CSF) proteome of patients with preeclampsia (PE) and normotensive pregnant women, in order to provide a better understanding of brain involvement in PE. Experimental design: Ninety-eight CSF samples (43 women with PE and 55 normotensive controls) were analyzed by LC–MS/MS proteome profiling. CSF was obtained during the spinal puncture before caesare
We model theoretically a two-dimensional electron gas (2DEG) covered by a superconductor and demonstrate that topological superconducting channels are formed when stripes of the superconducting layer are removed. As a consequence, Majorana bound states (MBSs) are created at the ends of the stripes. We calculate the topological invariant and energy gap of a single stripe, using realistic values for
We simultaneously measured the absorption and emission of single conjugated polymer poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) molecules in a poly(methyl methacrylate) (PMMA) matrix using near-critical xenon to enhance the photothermal contrast for direct absorption measurements. We directly measured the number of monomers and the quantum yield of single conjugated polymer
The configuration interaction (CI) method for calculating the exact eigenstates of a quantum-mechanical few-body system is problematic when applied to particles interacting through contact forces. In dimensions higher than one the approach fails due to the pathology of the Dirac δ-potential, making it impossible to reach convergence by gradually increasing the size of the Hilbert space. However, t
Tropical savannas and grasslands are estimated to contribute significantly to the total primary production of all terrestrial vegetation. Large parts of African savannas and grasslands are used for agriculture and cattle grazing, but the carbon flux data available from these areas are limited. This study explores carbon dioxide fluxes measured with the eddy covariance method for 3 years at a graze
In-situ knowledge of the gas composition close to a catalyst is essential for a better understanding of the gas–surface interaction. With planar laser-induced fluorescence (PLIF), the gas distribution around an operating catalyst can be visualized with high spatial and temporal resolution, in a non-intrusive manner. We report on a convenient setup using a nanosecond YAG-Dye laser system together w
Most avian migrants alternate flight bouts, characterized by high metabolic rates, with stopovers, periods of fuel replenishment through hyperphagia. High-energy metabolism and excessive calorie intake shift the balance between damaging prooxidants and antioxidants toward the former. Hence, migration likely affects the oxidative balance of birds. Migratory flight indeed appears to cause oxidative
Vissa ungdomar som upplevt potentiellt traumatiserande händelser kan utveckla dissociationssymptom. Under gynnsamma förhållanden har människor en förmåga att integrera känslor, tankar, sinnesintryck och minnen av livshändelser in i en adaptiv och sammanhängande självbild och berättelse om självet. Dissociation i samband med trauma kan beskrivas som ett sammanbrott av denna förmåga. Dissociativa upAfter experiencing potentially traumatic events (PTEs) some adolescents develop pathological dissociation. Trauma-related dissociation can be described as a break-down of the individual’s capacity to integrate emotions, thoughts, sensations, and memories about traumatic or other events into an adaptive and coherent self-image and self-narrative. Dissociative experiences (DE) include experienced lo
During the past decade there has been a resurgence of interest in the concept of recognition in international theory. Once the narrow concern of social theorists, the concept of recognition is nowadays invoked in at least three different senses in order to explain three different things. First, it is commonly used to explain how states and their identities are shaped by interaction, and how the mo
The placenta and tumors share important characteristics, including a requirement to establish effective angiogenesis. In the case of the placenta, optimal angiogenesis is required to sustain the blood flow required to maintain a successful pregnancy, whereas in tumors establishing new blood supplies is considered a key step in supporting metastases. Therefore the development of novel angiogenesis
A combination of mesoscale hydrodynamic simulations and microfluidic experiments are used to explore the use of cells' mechanical and dynamical properties as biomarkers for separation. Dynamic behaviour of red blood cells (RBCs) within deterministic lateral displacement (DLD) devices is investigated within various array geometries and for different viscosity contrasts between the intra- and extra-
We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.
Objective: This study assessed the applicability and outcomes of the closure of unused cuffs in branched endovascular aneurysm repair (b-EVAR) of thoracoabdominal aortic aneurysm. Methods: We reviewed b-EVAR procedures at a tertiary referral center to identify patients who underwent incomplete branching and needed closure of the unused branch cuffs. An electronic database and intraoperative and fo
