We discovered nocturnal colour vision in the Asian giant honeybee Apis dorsata - a facultatively nocturnal species - at mesopic light intensities, down to half-moon light levels (approx. 10 -2 cd m -2). The visual threshold of nocturnality aligns with their reported nocturnal activity down to the same light levels. Nocturnal colour vision in A. dorsata is interesting because, despite being primari
Aims: Subclinical carotid atherosclerosis adds predictive value to traditional risk factors for cardiovascular diseases (CVDs). Systematic Coronary Risk Assessment 2 (SCORE2), an algorithm composed of traditional risk factors, is a state-of-the-art to estimate the 10-year risk of first-onset CVDs. We aim to investigate whether and how subclinical carotid atherosclerosis affects the performance of
Minimizing insecticide use, preventing vector diseases and facilitating biodiversity assessments are suitable applications of recent advances in photonic insect surveillance and entomological lidar. The tools also comprise a new window into fundamental aspect of the fascinating life and ecology of insects and their predators in situ. At the same time, it is evident that lidars are subject to finit
With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. These undesirable consequences of fossil-based plastics have sparked a significant interest in develo
Many animals use camouflage to avoid detection by others, yet even the most inconspicuous objects become detectable against the background when moving1,2. One way to reduce detection while moving would be to ‘hide’ behind the movements of objects or other animals3. Here, we demonstrate experimentally that a common marine predator, the trumpetfish (Aulostomus maculatus), can conceal its approach fr
Background Among individuals with alcohol use disorder (AUD) and drug use disorder (DUD), is their genetic liability and its specificity moderated by substance availability? Methods Offspring (born 1960-1995) and their biological parents from three family types [not-lived-with (NLW) biological father, mother and adoptive] and their AUD and DUD diagnoses were ascertained from Swedish national regis
Konservat-Lagerstätten, such as the Toarcian (Early Jurassic) Posidonia Shale of southwestern Germany, are renowned for their spectacular fossils. Ichthyosaur skeletons recovered from this formation are frequently associated with soft tissues; however, the preserved material ranges from three-dimensional, predominantly phosphatized structures to dark films of mainly organic matter. We examined sof
The European Congenital Heart Surgeons Association (ECHSA) Congenital Database (CD) is the second largest clinical pediatric and congenital cardiac surgical database in the world and the largest in Europe, where various smaller national or regional databases exist. Despite the dramatic increase in interventional cardiology procedures over recent years, only scattered national or regional databases
In this chapter we take a look at the presence of emerging organic compounds (EOCs) in groundwater, with emphasis in sources of pollution, processes affecting the spatial and temporal concentration of these compounds as they move through the aquifer and interact with the soil. Emphasis is placed on the combination of transport mechanisms and physical and biogeochemical processes that combine for n
The ability to learn new tasks and quickly adapt to different variations or dimensions is an important attribute in agile robotics. In our previous work, we have explored Behavior Trees and Motion Generators (BTMGs) as a robot arm policy representation to facilitate the learning and execution of assembly tasks. The current implementation of the BTMGs for a specific task may not be robust to the ch
Reconfigurable intelligent surfaces (RISs) are being considered for 6G as they can facilitate favourable radio channels. To rigorously model the characteristics of an array antenna-based RIS, this paper proposes an approach to separately evaluatescatterings from the antenna elements and ground plane of RIS. Simulation results show that, depending on the absolute phases of variable loads in the RIS

Det övergripande syftet med denna studie, som ingick i forskningsprojektet Skånska hem: mottagande, etablering eller exkludering – hemlöshetspolitik och strategier för flyktingars bosättning, var att undersöka och beskriva Svalövs kommuns strategier för mottagande och bosättning av flyktingar och hemlösa kommuninvånare under åren 2018 till och med 2022. Forskningsprojektet ska ses mot bakgrund av
