For low-order adaptive optics systems, a method that is able to correct for system aberrations in the final focal plane is presented. The paper presents a novel figure of merit, corresponding to the integrated non-normalized tip-tilt-free optical transfer function. The inherent singular value decomposition modal content of the interaction matrix is used to optimize this figure of merit. The method

Non-western immigrants have a higher prevalence of type 2 diabetes and earlier onset than non-immigrant Swedes. In this 10-year follow-up including all people in Sweden diagnosed with type 2 diabetes from 2006 onwards (i.e. prescribed glucose lowering medication for type 2 diabetes), the total and cause-specific mortality of first-generation immigrants with type 2 diabetes is lower than in non-imm

The involvement of health professionals in research may ensure the acquisition of relevant and sustainable knowledge that is applicable in practice. However, knowledge is lacking about how professionals experience being involved. Therefore, the aim of this study was to explore how health professionals experienced the process of being involved in a project related to research on ageing and health.

Den här artikeln undersöker hur olika individer manifesterade sin person i byggnader under renässansen i Skåne. Genom en analys av stentavlor och träbjälkar med inskriptioner och bilder belyses frågor om identitet och individualitet. Föremålen placerades ofta ovanför dörrar i borgar och herrgårdar eller i byggnader som tillhörde städernas elit. Artikeln diskuterar vem som kunde se och förstå budsk

Dissolved organic matter (DOM) drives many fundamental biogeochemical processes (e.g., carbon storage, nutrient cycling, and soil development) in forest soil. However, the molecular-level characteristics of DOM derived from different types of tropical forest soils are poorly understood. Here, water samples at different soil depths (0, 20, and 40 cm) from tropical legume (Acacia auriculiformis, AA)

To enable the large-scale use of hydrogen fuel cells for mobility applications, convenient methods for on-board hydrogen storage and release need to be developed. A promising approach is liquid organic hydrogen carriers (LOHCs), since these are safe, available on a large scale and compatible with existing re-fuelling infrastructure. Usually, LOHC dehydrogenation is carried out in batch-type reacto

Världens främsta universitet har radikalt färre studenter som läser på grundnivå och en mångdubbelt större forskarutbildning än de främsta svenska universiteten.Det skriver Torsten Åkesson, professor i partikelfysik vid Lunds universitet.

Social resilience is relatively new rarely explored concept. In 21st century, it is becoming significant in sustainability studies in the context of social wellbeing and its impact on quality of life. The concept of social resilience is frequently associated withpredominant conceptualisation of resilience in Psychology. However, it goes beyond the narrow definition of resilience by assessing indiv

We derive a gap equation for bilayer excitonic systems based on density functional theory and benchmark our results against quantum Monte Carlo simulations and recent experiments on double bilayer graphene. The gap equation has a mean-field form but includes a consistent treatment of dynamical screening. We show that the gap survives at much higher densities than previously thought from mean-field

Survival after blood or marrow transplantation (BMT) for inborn errors of metabolism (IEM) is excellent; however, the burden of morbidity in long-term survivors of BMT for IEM remains understudied. This study examined the risk of chronic health conditions (CHC) in ≥2-year survivors of allogeneic BMT for IEM performed between 1974 and 2014 using the BMT Survivor Study. In this retrospective cohort

Chronic kidney disease and osteoporosis commonly co-exist in aged patients. Chronic kidney disease affects bone health because of its effect on mineral metabolism in the syndrome, Chronic Kidney Disease Mineral and Bone Disorder, resulting in an increased risk of fractures. Hip fracture risk may be as much as four-fold higher in the worst affected. Tools to estimate fracture risk such as FRAX® and

A large share of health-related information is today sought and communicated via the internet, including in social media. Questions have been raised about how this may affect health perceptions and behaviors, not least by enabling the communication of claims that contradict information from established medical authorities. As an example, knowledge claims about systemic side effects of the contrace

The past two decades have witnessed widespread scholarly interest in the role of cities in climate policy-making. This research has considerably improved our understanding of the local level in the global response to climate change. The present article synthesizes the literature on local climate policies with respect to the 1.5 °C target. While most studies have focused on pioneering cities and ne
