Spin–valley locking is ubiquitous among transition metal dichalcogenides with local or global inversion asymmetry, in turn stabilizing properties such as Ising superconductivity, and opening routes towards ‘valleytronics’. The underlying valley–spin splitting is set by spin–orbit coupling but can be tuned via the application of external magnetic fields or through proximity coupling. However, only

Background: The purpose of this study is to determine the prevalence and morbidity of neck pain with or without cervical rhizopathy, upper extremity motor deficit and/or thoracolumbar pain in elderly men. Methods: We conducted a cross-sectional questionnaire study of 3,000 community-dwelling older men with a mean age of 75.4 ± 3.2 years (range 69–81) to determine if they had experienced neck pain

The lifetime of an enzyme is critical to prevent system failure and optimize maintenance schedules in biological and analytical chemistry. The lifetime metrics of an enzyme can be evaluated from enzyme activity in terms of catalytic cycles per enzyme at various storage times. Trypsin, which is a gold-standard enzyme in proteomics, has been known to decrease activity due to self-digestion. To impro

En presentation av den allmänna borgutvecklingen inleder en katalogisering av 166 skånska borgplatser. Därefter presenteras 44 borgar med en fyllig beskrivning, bilder, rekonstruktioner samt analogt kartmaterial och en digital möjlighet att finna den aktuella lokalen.

In the following article, based on two years of participatory ethnographic field-work with the No-border musical, as well as interviews with 16 of the musical’s 30 participants, community theatre is investigated in a context of deportability. We analyse the working process in the theatre group, in which actors with and without resident permits participated, through the concept of politics of trans

The manuscript is devoted to optimal control for a class of linear positive systems with linear objective function and linear constraints. The solution to the corresponding Bellman equation is a linear value function, which can be found by linear programming.

A new class of palladium complexes bearing bidentate 2-hydroxypyridine based ligands have been prepared and fully characterized. The applications of these new complexes towards ketone alkylation reactions with alcohols through a metal-ligand cooperative borrowing-hydrogen (BH) process were demonstrated.

The interaction of alkali ions with multilayer graphene is critical in many applications, for example in energy storage devices. This requires a detailed understanding of ion interactions with carbonaceous layers. The mechanism of ion intercalation into graphene can be different from that observed for hard graphite. In this paper, we present an investigation of the vertical alkali ion (Na, K, Cs)

Vi lever i en värld där många människor inte har tillgång till rent vatten och faktorer som torka, föroreningar och ett dåligt vattenförvaltningssystem påverkar detta. På grund av sociala, politiska och ekonomiska faktorer, så är det också komplicerat för dessa människor att vara med i beslutsprocesser som kan påverkar deras tillgång till vatten. Men vad skulle hända om man kombinerade två olika vWater-related issues such as drought and water scarcity are problems that many countries around the world are facing. To solve this, multiple efforts have been made to combat these problems such as adopting Integrated Water Resource Management (IWRM) as a management approach. IWRM is a holistic approach that links different water systems and has therefore been popularized and conceptualized by man

MicroRNAs are short non-coding RNAs with important functions in the regulation of gene expression in healthy and diseased tissues. To optimally utilize the biological and clinical information that is contained in microRNA expression levels, tools for their accurate and cost-effective quantification are needed. While the standard method, qPCR, allows for quick and cheap microRNA quantification, spe
