Group-III nitrides have transformed solid-state lighting and are strategically positioned to revolutionize high-power and high-frequency electronics. To drive this development forward, a deep understanding of fundamental material properties, such as charge carrier behavior, is essential and can also unveil new and unforeseen applications. This underscores the necessity for novel characterization t

BACKGROUND: The role of ribonucleases in tuberculosis among people with human immunodeficiency virus (HIV; PWH) is unknown. We explored ribonuclease activity in plasma from PWH with and without tuberculosis.METHODS: Participants were identified from a cohort of treatment-naive PWH in Ethiopia who had been classified for tuberculosis disease (HIV positive [HIV+]/tuberculosis positive [tuberculosis+

We investigate the properties of a Fibonacci quasicrystal (QC) arrangement of a one-dimensional topological superconductor, such as a magnetic atom chain deposited on a superconducting surface. We uncover a general mutually exclusive competition between the QC properties and the topological superconducting phase with Majorana bound states (MBS): there are no MBS inside the QC gaps and the MBS neve

BackgroundThe relationship between sleeping habits and aortic stiffness remains inconclusive and is not fully explored in the European general population.MethodsWe examined cross-sectionally 8659 participants from the Swedish population-based cohort Swedish CArdioPulmonary bioImage Study (SCAPIS), mean age 57.5 years, 52.1% women. A self-administered questionnaire on sleeping habits (duration, qua

The goal of the TEDDY (The Environmental Determinants of Diabetes in the Young) study is to elucidate factors leading to the initiation of islet autoimmunity (first primary outcome) and those related to progression to type 1 diabetes mellitus (T1DM; second primary outcome). This Review outlines the key findings so far, particularly related to the first primary outcome. The background, history and

In this work we consider superconductor-semiconductor hybrids containing both trivial and Majorana zero modes and explore their signatures in the Majorana polarization. In particular, we consider trivial zero-energy states due to confinement and disorder, which seem to be very likely experimental scenarios. We show that the Majorana polarization is able to characterize the topological phase transi

PURPOSE: We studied the relative contributions of total peripheral resistance (TPR), stroke volume (SV) and heart rate (HR) to low blood pressure in classical orthostatic hypotension (cOH) on group and individual levels.METHODS: We retrospectively analyzed tilt test records from cOH patients and age/sex-matched controls. We quantified relative effects of HR, SV and TPR on mean arterial pressure (M

The anisotropic optical absorption edge of β-Ga2O3 follows a modified Beer-Lambert law having two effective absorption coefficients. The absorption coefficient of linearly polarized light reduces to the least absorbing direction beyond a critical penetration depth, which itself depends on polarization and wavelength. To understand this behavior, a Stokes vector analysis is performed to track the p

Fabrication of CoNb2O6 thin films was possible through spin-coating an alkali-free, aqueous solution of a polyoxoniobate ([Nb10O28]6-, Nb10) and a cobalt nitrate (Co(NO3)2), followed by annealing. The results showed that depending on the calcination conditions, minor phases of unreacted Co3O4 and β-Nb2O5 may form alongside the columbite CoNb2O6 phase. However, optimizing the calcination conditions

AimsThe pathophysiology of orthostatic hypotension (OH), a common clinical condition, associated with adverse outcomes, is incompletely understood. We examined the relationship between OH and circulating endostatin, an endogenous angiogenesis inhibitor with antitumor effects proposed to be involved in blood pressure (BP) regulation.MethodsWe compared endostatin levels in 146 patients with OH and 1

The wide range of properties, relative ease and low cost of using Deep Eutectic Solvents garners them interest in an ever expanding range of applications. Among common DES components many are naturally occurring chiral molecules. Here we present the liquid structure of either single enantiomeric or racemic tartaric acid with choline chloride at a molar ratio of 2 choline chloride to 1 tartaric aci

Many emergent phases of matter stem from the intertwined dynamics of quasiparticles. Here we show that a topological superconducting phase emerges as the result of interactions between electrons and magnons in a quantum wire and a helical magnet. The magnon-mediated interaction favors triplet superconductivity over a large magnetic phase space region, and stabilizes topological superconductivity o

The sometimes rapid development of (new) threats and extraordinary events calls for a robust, flexible, and well-equipped civil crisis preparedness system to respond and limit the damage of crisis events. To achieve this, Swedish municipalities and regions are required by law to regularly perform and report risk and vulnerability analysis ‘bottom up’ to governmental agencies. When performed in lar

The impact of different carbon concentrations in the Al 0.06 Ga 0.94 N graded back-barrier and GaN buffer of high electron mobility transistors (HEMTs) is investigated. Four epi-wafers with different carbon concentrations, ranging from 1 × 10 17 to 5 × 10 17 cm −3 , were grown by metal organic chemical vapor deposition (MOCVD). HEMTs with 100 and 200 nm gate lengths were fabricated and characteriz

Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an alternating current bias can tune the response of such a diode. We show that for slow driving there is always a regime where the system can only carry zero-voltage dc current in one direction, thus effectively behaving as an i

Objective: To explore factors associated with change in empowerment in patients that have participated in a 3-month Supported Osteoarthritis Self-Management Program (SOASP). Further, to evaluate empowerment in the longer term. Design: An explorative analysis including patients from a cohort study conducted in primary healthcare in Sweden was performed. Univariable linear regression models were per
