Several models of physics beyond the Standard Model predict the existence of dark photons, light neutral particles decaying into collimated leptons or light hadrons. This paper presents a search for long-lived dark photons produced from the decay of a Higgs boson or a heavy scalar boson and decaying into displaced collimated Standard Model fermions. The search uses data corresponding to an integra
Educational research in higher education needs a methodology for how to think and act in relation to how pedagogical interactions support learning. A methodology that can identify how pedagogical rhetorical qualities, such as confidence and a desire to learn, are embedded in a pedagogical interaction. This article presents an outline of a pedagogical rhetorical interactional methodology that enabl
A search for Higgs boson pair production via vector-boson fusion (VBF) in the bb¯ bb¯ final state is carried out with the ATLAS experiment using 126 fb−1 of proton- proton collision data delivered at s = 13 TeV by the Large Hadron Collider. This search is sensitive to VBF production of additional heavy bosons that may decay into Higgs boson pairs, and in a non-resonant topology it can constrain th
A search for dijet resonances in events with at least one isolated charged lepon is performed using 139 fb−1 of s = 13 TeV proton-proton collision data recorded by the ATLAS detector at the LHC. The dijet invariant-mass (mjj) distribution constructed from events with at least one isolated electron or muon is searched in the region 0.22 < mjj< 6.3 TeV for excesses above a smoothly falling backgroun
Fire smoke in a tunnel fire is a key factor causing casualties, thus the critical longitudinal ventilation velocity is a key parameter in tunnel fire safety ventilation design. The correlation of critical longitudinal ventilation velocity for smoke control in a tunnel induced by two nearby fires has rarely been studied experimentally and quantified before, despite the fact that this scenario exist
Austria, Finland and Sweden became members of the EU in 1995. This paper examines how support for the euro and trust in the European Central Bank (ECB) have evolved in these three countries since their introduction at the turn of the century. Support for the euro in the two euro-area members Austria and Finland has remained high and relatively stable since the physical introduction of the new curr
OBJECTIVE: This study explored the association of patients' demographics, health status, symptom severity, previous osteoarthritis (OA) care, and psychological status with the change in pain severity following a first-line intervention including education and exercise for OA provided nationwide in Swedish primary care. METHODS: This register-based cohort study included 23,309 people with knee or h
The armed conflict shaped and determined land-uses, water access and social and environmental norms in highlands regions in Colombia for several decades. The withdrawal of the Revolutionary Armed Forces of Colombia (FARC) after the Peace Agreement with the government of Colombia in 2016, has brought new dynamics in access and uses of land leading to increasingly visible social-environmental impact
Digital and scalable technologies are increasingly important for rapid and large-scale assessment and monitoring of land cover change. Until recently, little research has existed on how these technologies can be specifically applied to the monitoring of Reducing Emissions from Deforestation and Forest Degradation (REDD+) activities. Using the Google Earth Engine (GEE) cloud computing platform, we
We present a qualitative physical model of the origin of two very brightUV lines of Fe II at 2507-2509 Å, present in high-resolutionspectra of gaseous condensations (blobs) close to the central star ofeta Carinae. The spectra have been obtained with the Hubble SpaceTelescope (HST). The model is based on a type of Bowen mechanism withselective photoexcitation of Fe II by a broad HLyalpha profile,ge
To determine if an inhibition of the endocannabinoid-degrading enzyme fatty acid amide hydrolase (FAAH) can counteract the changes in urodynamic parameters and bladder afferent activities induced by intravesical prostaglandin E2 (PGE2 )-instillation, we studied effects of URB937, a peripherally-restricted FAAH inhibitor, on single-unit afferent activity (SAA) during PGE2 -induced bladder overactiv
In this report we show that Tyr568 and Tyr570 are phosphorylated in vivo in the Kit/stem cell factor receptor (Kit/SCFR) following ligand-stimulation. By mutation of Tyr568 and Tyr570 to phenylalanine residues and expression of the mutated receptors in porcine aortic endothelial (PAE) cells, we could demonstrate a loss of activation of members of the Src family of tyrosine kinases when Tyr568 was
BACKGROUND: Reports on perioperative complications after postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) for nonseminoma germ cell tumour (NSGCT) are from experienced single centres, with a lack of population-based studies. OBJECTIVE: To assess the complications of bilateral and unilateral PC-RPLND. DESIGN, SETTING, AND PARTICIPANTS: A prospective, population-based, observational
The IL22RA2 locus is associated with risk for multiple sclerosis (MS) but causative variants are yet to be determined. In a single nucleotide polymorphism (SNP) screen of this locus in a Basque population, rs28385692, a rare coding variant substituting Leu for Pro at position 16 emerged significantly (p = 0.02). This variant is located in the signal peptide (SP) shared by the three secreted protei
A 125I-protein A-binding assay detecting antibodies to cell surface antigens on human blood cells was developed and evaluated using sera from multitransfused nonleukemic patients sensitized against HLA antigens. The binding assay was found to be reproducible and more sensitive than conventional HLA testing. Seven patients with acute myelogenous leukemia and two patients with acute lymphoblastic le
This paper aimed to study the agreement and repeatability, both intra- and interobserver, of infrapopliteal lesion assessment with magnetic resonance angiography (MRA), using the TransAtlantic Inter-Society Consensus (TASC) II criteria, with perioperative digital subtraction angiography (DSA) as a reference. Sixty-eight patients with an MRA preceding an endovascular infrapopliteal revascularizatio
BACKGROUND Limited information exists about the epidemiology and outcome of surgical patients at increased risk of postoperative pulmonary complications (PPCs), and how intraoperative ventilation was managed in these patients. OBJECTIVES To determine the incidence of surgical patients at increased risk of PPCs, and to compare the intraoperative ventilation management and postoperative outcomes w
