An optimal plasmonic resonance is derived for small homogeneous and isotropic inclusions in a lossy surrounding medium. The optimal resonance is given in terms of any particular eigenmode (electrostatic resonance) associated with the double-layer potential for a smooth, but otherwise arbitrary surface.

This article is based on a larger research project with the purpose to study how market aesthetics and student’s music culture are expressed in the Swedish music classroom. The empirical material consists of video observations of classroom activities in secondary school settings in Sweden. The theoretical framework consists of poststructuralist and social constructionist theory combined with theor

Transboundary research collaborations (TRCs) are critical in supporting evidence-based actions to address complex global issues. However, there is still a lack of empirics, which would detail how TRCs are organised, how activities are facilitated, and how actors interplay. In this article, we address this gap through the evaluation of a North-South TRC against the 11 principles for TRCs by the Com

Muhammad Hejazi, deputy head of the Iranian Quds Force, is reported to have died of heart disease. However, a mysterious tweet hints that he might have been killed.

Pollutant transport in the unsaturated soil zone is a potential threat to surface and ground water resources. The intensity and volume of rainfall are the parameters that decide how fast and deep the pollutants will be transported. Climate models predict a future rainfall climate with higher total volume and higher intensities. In the present study we try to assess effects on unsaturated solute tr

Closed-loop control of cloud resources requires there to be measurements readily available from the process in order to use the feedback mechanism to form a control law. If utilizing state-feedback control, sought states might be unfeasible or impossible to measure in real applications; instead they must be estimated. However, running the estimators in real time for all measurements will require a

For many applications, including future giant telescopes, there is increased interest in structural cables. Usually integrated models, i.e. combined models of structures, optics and control systems are used for modeling of telescopes. Performance of structural cables is non-linear, so often a linearization is needed to include cable models in integrated models of telescopes. We present two differe

Parasites can vary in the number of host species they infect, a trait known as “host specificity”. Here we quantify phylogenetic signal—the tendency for closely related species to resemble each other more than distantly related species—in host specificity of avian haemosporidian parasites (genera Plasmodium, Haemoproteus and Leucocytozoon) using data from MalAvi, the global avian haemosporidian da

The human genome encodes 13 aquaporin isoforms with characteristic substrate specificity that are expressed at specific locations throughout the body. Of these isoforms, AQPs 1-4 serve important functions in renal water reabsorption. Consequently, specific AQP inhibitors have been proposed as 'aquaretics', a new class of drugs suitable to induce diuresis without concomitant salt wasting. Furthermo

Purpose: The purpose of this paper is to investigate the thermal performance of the cooling plates with conventional straight channel and wavy channel designs. Design/methodology/approach: A three-dimensional model involving coupled fluid flow and heat transfer processes is developed to study the thermal performance of the cooling plates. The effects of wavelength and amplitude on the cooling perf

Zinc status was evaluated in 30 subjects with Crohn's disease. Intestinal resection had previously been performed in 23 of the subjects. The concentrations of zinc were determined in plasma, erythrocytes, percutaneous muscle biopsies, and in urine collected during 24 hours. The results were compared with those in 19 healthy controls. Most of the patients had a normal zinc status. The levels of zinZinc status was evaluated in 30 subjects with Crohn's disease.

I den här studien används extremvärdesanalys för att beräkna våguppspolning och årlig dynerosion med 10, 50, och 100 års återkomsttid. Frekvensanalysen baseras på en 40 år lång tidsserie med simulerad dynerosion och våguppspolning från Ängelholms strand i Skälderviken. Med SMB-metoden beräknas vågor ute till havs som sedan transformeras till kustnära vågor i vågmodellen SWAN. Våguppspolningen berä

Risk factors for suicidal behaviour include adverse life events as well as biochemical parameters acting, e.g. within the hypothalamic-pituitary-adrenal axis and/or monoaminergic systems. The aim of the present investigation was to study stressful life events and biological stress markers among former psychiatric inpatients, who were followed up 12 years after an index suicide attempt. At the time

Enterohemorrhagic Escherichia coli (EHEC) infection leads to marked intestinal injury. Sigmoid colon obtained from two children during EHEC infection exhibited abundant TUNEL-positive cells. To define which bacterial virulence factors contribute to intestinal injury the presence of Shiga toxin-2 (Stx2), intimin and the type III secretion system were correlated with symptoms and intestinal damage.
