Harvesting the excess energy from absorbed above bandgap photons is a promising approach to overcome the detailed balance limit for higher solar cell efficiencies. However, this remains very challenging for 2D layered halide perovskites as the fast excess energy loss competes effectively with charge extraction. Herein, the authors engineer the energy cascade manifold of quantum well (QW) states in
Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents
TensorView for MATLAB is a GUI-based visualization tool for depicting second-rank Cartesian tensors as surfaces on three-dimensional molecular models. Both ellipsoid and ovaloid tensor display formats are supported, and the software allows for easy conversion of Euler angles from common rotation schemes (active, passive, ZXZ, and ZYZ conventions) with visual feedback. In addition, the software dis
Flicker, or more precisely temporal light modulation (TLM), has re-emerged as a problem with the introduction of LED-based lighting technology. TLM, meaning variations in light intensity over time, may have negative effects on human health, causing annoyance, headaches, eyestrain and migraine. In addition to the unnecessary suffering TLM causes in individuals, the negative consequences of TLM crea
Background: The aim was to review available biokinetic data, collect own experimental data, and propose an updated compartmental model for 2-[18F]FDG in the frame of the revision of the ICRP report on dose coefficients for radiopharmaceuticals used in diagnostic nuclear medicine. Methods: The compartmental model was developed based on published biokinetic data for 2-[18F]FDG. Additional data on ur
Neuroblastoma is a childhood cancer derived from the sympathetic nervous system. High-risk neuroblastoma patients have a poor overall survival and account for ~15% of childhood cancer deaths. There is thus a need for clinically relevant and authentic models of neuroblastoma that closely resemble the human disease to further interrogate underlying mechanisms and to develop novel therapeutic strateg
Flimmer, eller närmare bestämt temporal ljusmodulering (TLM), har återigen blivit ett problem i samband med införandet av LED-baserad belysningsteknik. TLM, dvs. variationer i ljusintensiteten över tiden, kan ha en negativ inverkan på människors hälsa och orsaka irritation, huvudvärk, ögonbesvär och migrän. Förutom det onödiga lidande som TLM orsakar för enskilda personer utgör de negativa konsekv
Rapporten är en sammanfattning av en litteratur- och intervjustudie som behandlar nya aspekter av tillgänglighet, nämligen den digitala tillgängligheten. Rapporten består av en del som behandlar så kallad grå litteratur, det vill säga rapporter, utredningar och policydokument från olika aktörer som berör den digitala tillgängligheten. Denna litteratur kopplas till viss del också till vetenskaplig
Den första enkäten i den Svenska Handelslogistik-panelen visar på flera trender som påverkar handelsföretag och framtida automatisering av lager. Rapporten pekar på en fortsatt snabb tillväxt både vad gäller omsättning, sortimentsstorlek och sortimentsbredd. Det sker en markant ökning av handelsföretag med hög grad av integration av butik och e-handel (s.k. omnikanal). Företagen säljer huvudsakligDen första enkäten i den Svenska Handelslogistik-panelen visar på flera trender som påverkar handelsföretag och framtida automatisering av lager.

In the wake of crises and “enlargement fatigue”, EU politics deprioritized enlargement. Recently, however, the Commission motioned a reinvigorated enlargement prospect for the Western Balkans, identifying Serbia and Montenegro as the front runners. This paper advises that in going forward, the EU should also look back at its five decades of enlargement. The article focuses on environmental protect
Material interfaces can occur at different material length scales. Understanding the properties and the behaviour of interfaces is of utmost importance because interfaces can significantly influence the effective constitutive response of the material under consideration. Based on the fundamentals of electro-mechanically coupled cohesive zone formulations for electrical conductors and on the associ
The post examines connections between global North, and particularly European, efforts to address climate- and disaster-related displacement in climate vulnerable countries, and the externalization policies implemented by those same countries to prevent refugee and migratory movements.
We present the CarbonTracker Europe High-Resolution (CTE-HR) system that estimates carbon dioxide (CO2) exchange over Europe at high resolution (0.1 × 0.2° ) and in near real time (about 2 months' latency). It includes a dynamic anthropogenic emission model, which uses easily available statistics on economic activity, energy use, and weather to generate anthropogenic emissions with dynamic time pr
Plant mitochondria produce the majority of adenosine triphosphate (ATP) – the cellular energy currency for metabolic reactions needed for plant growth, development, and maintenance. Despite a relatively thorough understanding of basic mitochondrial functions, many mitochondrial proteins and processes remain poorly understood. The aims of this thesis are to i) review and compare the mitochondrial u
Over the past 50 years there has been considerable progress in our understanding of biomolecular interactions at an atomic level. This in turn has allowed molecular simulation methods employing full atomistic modelling at ever larger scales to develop. However, some challenging areas still remain where there is either a lack of atomic resolution structures or where the simulation system is inheren
At present time, it has been stated that “Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850–1900 in 2011–2020”. Therefore, understanding the consequences of human activities on present and future climate is one of the most important issues of this century. It is not the first time
