Horizontal drift of the beam on the MAX IV soft x-ray beamlines was observed with a 1-2 hour settling time and strong dependence on the undulator power setting. A water cooled, suspended electrode was designed and is shown to reduce the horizontal beam drift on three MAX IV soft x-ray beamlines to acceptable operational levels.
BACKGROUND AND OBJECTIVES: Multiple system atrophy (MSA) is a neurodegenerative disorder characterized by 3 core symptom complexes: parkinsonism, cerebellar syndrome, and dysautonomia. Recent Movement Disorder Society (MDS) criteria allow for the clinical diagnosis of MSA based solely on motor symptoms, without requiring dysautonomia. This study aimed to evaluate the frequency and disease trajecto
Endovascular therapy (EVT) has proven benefit for patients with anterior circulation large vessel occlusion (LVO) strokes with moderate-to-severe deficits, but its value in patients presenting 6-24 hours after onset with mild symptoms (NIH Stroke Scale score ≤5) remains unclear. This journal club article examines a retrospective analysis of CLEAR registry data comparing EVT with medical management
In this chapter, the salutogenic framework is applied as a theoretical foundation for health promotion. Health promotion and salutogenesis are intertwined. In this chapter, they are therefore compared using their respective value sets in the search for coherent interpretations. Some core concepts of salutogenesis and health promotion, such as health, wellbeing, quality of life and human rights are
Background The prognostic value of fractional flow reserve (FFR) in assessing coronary stenosis before transcatheter aortic valve replacement (TAVR) is unclear. Objectives The aim of this study was to evaluate cardiovascular risks associated with significant and nonsignificant FFR values of coronary stenosis prior to TAVR. Methods Patients were enrolled from the NOTION-3 (Nordic Aortic Valve Inter
Interference between scattering channels is observed in resonant inelastic x-ray scattering (RIXS) at the Ne K threshold. Final states with |2p-1np⟩ as the main configuration are populated via |1s-1n′p⟩ resonances, where large-amplitude one-electron (n′=n) channels interfere with small-amplitude two-electron (n′≠n) channels. The interference is manifested in an asymmetric line profile where the tw
Background: Hearing loss is estimated to affect more than 20% of the global population. Hearing aid fitting is a common intervention in audiological rehabilitation; however, there are still those who struggle with remaining communication difficulties that require additional intervention. The group rehabilitation program Active Communication Education (ACE) has been shown to be an effective alterna
Insect-mediated pollination enhances global production of many crops, and evidence highlights that insect pollination can also improve crop quality. The link between insect-mediated pollination and crop quality is driven not only by insect pollinators, but by a complex of interactions between pollinators, plant genotype, levels of cross pollination, plant physiology, environmental conditions, farm
This is the first comprehensive checklist and conservation assessment of the bee (Hymenoptera: Apoidea) fauna of the State of Vermont. This checklist of 351 species (plus 1 morphospecies) is based on 79,206 open-access data records available from the Global Biodiversity Information Facility (GBIF), nearly all (98%) of which were identified by an author or trusted collaborator, including 100% of th
Pesticide use and habitat loss are major anthropogenic drivers of bee decline, raising global concerns about impaired crop pollination. However, the relative importance of these stressors and their combined impact on bee assemblages comprising species with different traits, such as body size or nesting strategy, remains unknown. Here we addressed these key knowledge gaps in a global quantitative s
We study applications of clustering (in particular the k-center clustering problem) in the design of efficient and practical deterministic algorithms for computing an approximate and the exact arithmetic matrix product of two 0-1 rectangular matrices A and B with clustered rows or columns, respectively. Let λA and λB denote the minimum maximum radius of a cluster in an ℓ-center clustering of the r
Good Behavior Game (GBG) is a school-based intervention designed to reduce conduct problems, while increasing on-task behavior and a positive classroom climate. Earlier studies have shown positive long-term effects in several outcomes, making GBG a promising method of universal prevention. This study evaluates the effectiveness of a translated and adapted version of GBG in a pragmatic, cluster-ran
This study compared and examined the electroencephalogram(EEG)-based driver inattention warning system with actual bus drivers in real-road environments. EEG and survey data were gathered from 20 professional bus drivers who drove their buses under the conditions in which the warning systems were turned on and off for 47 days. The analysis revealed that the ratio of the SMR-mid beta to theta(RSMT)
Despite significant efforts to reconstruct the Holocene glacial history in Scandinavia, evidence of glacier fluctuations in Sweden has mostly been limited to palaeoclimatic proxies, while dating of direct geological evidence from glacier forelands is still rare. This is the first study in Sweden that has attempted to fully reconstruct dynamics, chronology and palaeoclimate of a glacier throughout
Background: Inhalation (Sniffing) of N2O among adolescents has increased in Sweden during recent years. Both neurological and thromboembolic consequences have been reported. This study aims to evaluate the association between a sensation-seeking personality and sniffing of N2O among students attending schools in Stockholm. Method: Students, 15–18 years old, from 77% of schools in Stockholm partici
Ecological degradation not only affects local and global environments but also threatens the cultural survival of affected societies, exemplifying the phenomenon known as the genocide–ecocide nexus. This article presents the first comparative case study of olive tree destruction in occupied Palestine and Afrin canton of Rojava, highlighting how ecocide serves as a deliberate strategy of cultural a
