BACKGROUND: Subarachnoid haemorrhage (SAH) is a devastating disease, with high mortality rate and substantial disability among survivors. Its causes are poorly understood. We aimed to investigate risk factors for SAH using a novel nationwide cohort consortium. METHODS: We obtained individual participant data of 949 683 persons (330 334 women) between 25 and 90 years old, with no history of SAH at
Political connection in China is often tested for correlation with business success and government support under a suspicion that connected entrepreneurs enjoy special favors and protection. Research evidence is mixed. In revisiting the debate on political capital in China, we apply a socially embedded perspective on political connection. To this end we introduce two methodological innovations: (a
The molybdenum cofactor is an important cofactor, and its biosynthesis is essential for many organisms, including humans. Its basic form comprises a single molybdopterin (MPT) unit, which binds a molybdenum ion bearing three oxygen ligands via a dithiolene function, thus forming Mo-MPT. In bacteria, this form is modified to form the bis-MPT guanine dinucleotide cofactor with two MPT units coordina
Hand movement is controlled by a large number of muscles acting on multiple joints in the hand and forearm. In a forearm amputee the control of a hand prosthesis is traditionally depending on electromyography from the remaining forearm muscles. Technical improvements have made it possible to safely and routinely implant electrodes inside the muscles and record high-quality signals from individual
OBJECTIVE: There are historical and theoretical indications of a difference in subjective experience between autism spectrum disorder (ASD) and the schizophrenia spectrum. However, this difference has not been empirically explored. Therefore, to explore potential differences in subjective experience between the 2 spectra, we examined the presence/absence of self-disorders in Asperger syndrome/auti
Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. Engine emissions such as carbon dioxide that has an effect on a global scale and other harmful emissions that affect on a local scale such as soot and nitrogen oxides are on the rise, forcing the countries to t
Förra sommaren gästades SLF den 13–17 juni av den brittiska motsvarigheten BLS genom en inbjudan av Lars Borg, som ibland gästat deras exkursioner i England. Vi var förlagda till Allégården i Kastlösa på Öland varifrån vi gjorde utflykter till olikadelar av södra och mellersta Öland. En halvdag ägnades också åt en typiskt sur tallskog på fastlandet i närheten av Kalmar. Här berättar Ulf om den hisBrigantiaea crystallina Arup is described as new to science from South Korea and Japan. It is similar to B. purpurata but has a pale to pale brownish orange hypothecium, an excipulum penetrated by brownish orange anthraquinonecrystals as well as colourless crystals that appear white in polarised light, the spores are smaller and the thallus lacks zeorine. The new species is illustrated and compare
Objectives: The purpose of this study was to modify a clinical linear accelerator, making it capable of electron beam ultra-high dose rate (FLASH) irradiation. Modifications had to be quick, reversible, and without interfering with clinical treatments. Methods: Performed modifications: (1) reduced distance with three setup positions, (2) adjusted/optimized gun current, modulator charge rate and be
Importance: Genetic studies of intracerebral hemorrhage (ICH) have focused mainly on white participants, but genetic risk may vary or could be concealed by differing nongenetic coexposures in nonwhite populations. Transethnic analysis of risk may clarify the role of genetics in ICH risk across populations. Objective: To evaluate associations between established differences in ICH risk by race/ethn
Purpose: The number of childbirths among cancer survivors continues to increase, but it is still largely unknown whether the children of cancer survivors might experience adverse health outcomes during the process of growing up. Methods: We identified all individuals diagnosed with cancer between 1958 and 2015 from the Swedish Cancer Registry and linked them to the Swedish Medical Birth Register t
Transport of people and freight on-road have a big impact on the total energy use in the world. The majority of these transports is propelled with diesel engines and the reason is simply that the diesel engine is better than the gasoline engine due to lower fuel consumption. But the cost of this is the increase in dangerous nitrogen oxides (NOx). Around 10 000 people dies everyyear due to emission
Safe drinking water is delivered to the consumer through kilometres of pipes. These pipes are lined with biofilm, which is thought to affect water quality by releasing bacteria into the drinking water. This study describes the number of cells released from this biofilm, their cellular characteristics, and their identity as they shaped a dri
In order to significantly improve engine efficiency and reduce exhaust emissions at the same time, new radical combustion concepts have emerged. Gasoline partially premixed combustion (PPC) is one of them, with early results showing high gross indicated efficiency. To achieve that, PPC relies on high EGR (exhaust gas recirculation) use, with numbers that can reach up to 50%. Such a high amount of
We consider least-squares approximation of a function of one variable by a continuous, piecewise-linear approximand that has a small number of breakpoints. This problem was notably considered by Bellman who proposed an approximate algorithm based on dynamic programming. Many suboptimal approaches have been suggested, but so far, the only exact methods resort to mixed integer programming with super
Magnetic sensing is used to structure every-day, non-migratory behaviours in many animals. We show that crayfish exhibit robust spontaneous magnetic alignment responses. These magnetic behaviours are altered by interactions with Branchiobdellidan worms, which are obligate ectosymbionts. Branchiobdellidan worms have previously been shown to have positive effects on host growth when present at moder
Background Native aortic and mitral valve infective endocarditis (AVE and MVE, respectively) are usually grouped together as left-sided native valve infective endocarditis (LNVE), while the differences between AVE and MVE have not yet been properly investigated. We aimed to compare AVE and MVE in regard to patient characteristics, microbiology and determinants of survival. Methods We conducted a r
This chapter covers transition metal complexes with phosphorus-based pincer ligands with a central sp3-hybridization. It primarily focusses on progress in the last 4 years. The ligand types covered in this chapter include those based on straight alkyl chains but also complexes based on cyclohexane, dibenzobarrelene, cycloheptatriene, and diarylmethane scaffolds.
