We describe a device to study reactions relevant for the Single Event Effect (SEE) in microelectronics by means of 200A and 300AMeV, inverse kinematics, Si + H and Si + D reactions. The work is focused on the possibility to measure Z = 2-14 projectile fragments as efficiently as possible. During commissioning and first experiments the fourth quadrant of the CELSIUS storage ring acted as a spectrom
The procedure of aligning a positron emission tomography (PET) image with a common coordinate system, spatial normalization, typically demands a corresponding structural magnetic resonance (MR) image. However, MR imaging is not always available or feasible for the subject, which calls for enabling spatial normalization without MR, MR-less spatial normalization. In this work, we propose a template-
BACKGROUND: Cognitive fatigue after childhood cancer is frequently overlooked despite guidelines recommending follow-up, and might be mistaken for depression due to overlapping symptoms. Our objectives were: 1) to examine ratings of fatigue in survivors of paediatric brain tumours (BT) and acute lymphoblastic leukaemia (ALL) compared to healthy controls, 2) to examine the relationship between symp
Massive MIMO is a promising technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes in groups that can communicate simultaneously such that the mutual interference is minimized. We here propose node partitioning strategies that do not require full channel state in
Employing the heuristic of intersectionality, this study analyzes household effects and responses to water shortage in Gaborone, Botswana, focusing on residents’ adaptive capacity and vulnerability. Using data collected through qualitative interviews, we find that households from all socio-economic backgrounds face various effects from water shortage and use numerous strategies to reduce exposure
Purpose: To investigate the reasons for not proceeding to surgery in patients undergoing presurgical evaluation for epilepsy. Methods: A retrospective cohort study of 401 consecutive patients who were evaluated for but did not proceed to surgery for epilepsy between 1990 and 2016 at three Swedish epilepsy surgery centers was performed. Reasons for not proceeding to surgery were categorized as inco
Glucagon receptor (Gcgr) signaling maintains hepatic glucose production during the fasting state; however, the importance of the Gcgr for lipid metabolism is unclear. We show here that fasted Gcgr-/- mice exhibit a significant increase in hepatic triglyceride secretion and fasting increases fatty acid oxidation (FAO) in wild-type (WT) but not in Gcgr-/- mice. Moreover fasting upregulated the expre
We derive short-distance constraints for the hadronic light-by-light contribution (HLbL) to the anomalous magnetic moment of the muon in the kinematic region where the three virtual momenta are all large. We include the external soft photon via an external field leading to a well-defined Operator Product Expansion. We establish that the perturbative quark loop gives the leading contribution in a w
Intermodality or combining more than one transport mode during a single trip has been put forward to facilitate a modal shift from private car to more environmentally friendly modes such as public transport, cycling or walking. Bike-and-ride – that is, integrating cycling and public transport in one trip – is an attractive combination, as cycling as an active and clean mode is faster than walking
Agricultural soils contribute to human welfare through their generation of manifold ecosystem services such as food security, water quality and climate regulation, but these are degraded by common farming practices. We have developed a roadmap for evaluating the contribution of both private- and public-good ecosystem services generated by agricultural soils to societal welfare. The approach consid
There is an urgent need to address in a comprehensive manner the problem of systematic and flagrant violations of international humanitarian and human-rights law in ongoing conflicts, including its sources and implications. More specifically, possible lines of action to counter the growing importance of non-state armed actors and the use of explosives in populated areas must be discussed. A Global
In a joint experimental and theoretical study on metallic TbSi2 nanowires, we observe a continuous crossover from a two-dimensional (2D) to a quasi-one-dimensional (1D) electronic structure by reduction of the nanowire width. The nanowires were grown by self-organization on vicinal Si(111) substrates denoted by the Miller indices (hhk). Their electronic structure was analyzed by angle-resolved pho
Background: Genome-wide association studies (GWAS) have proven successful in predicting genetic risk of disease using single-locus models; however, identifying single nucleotide polymorphism (SNP) interactions at the genome-wide scale is limited due to computational and statistical challenges. We addressed the computational burden encountered when detecting SNP interactions for survival analysis,
With the use of genetic technology, researchers have the potential to inform medical diagnoses and treatment in actionable ways. Accurate variant interpretation is a necessary condition for the utility of genetic technology to unfold. This relies on the ability to access large genomic datasets so that comparisons can be made between variants of interest. This can only be successful if DNA and medi
The time and temperature dependent dynamic modulus of asphalt concrete is a key parameter to modern pavement design and to pavement quality. However, accurate measurements of the complex modulus through conventional cyclic testing are expensive regarding both time and costs. Novel test methods based on modal analysis facilitate economic, accurate and faster determination of linear viscoelastic mat
Some theoretical approaches are reviewed to analyze crystallographic and optical properties of phosphors for white light emitting diodes. Stresses are placed on 1) local electro-neutrality for the structural stability of hosts, and 2) dielectric property and coordination of anion ligands around rare-earth luminescent centre for the tuning of emission colour. First-principles calculation results ar
BACKGROUND: Bacterial surfaces are complex systems, constructed from membranes, peptidoglycan and, importantly, proteins. The proteins play crucial roles as critical regulators of how the bacterium interacts with and survive in its environment. A full catalog of the motifs in protein families and their relative conservation grade is a prerequisite to target the protein-protein interaction that bac
