A search for events with two displaced vertices from long-lived particle (LLP) pairs using data collected by the ATLAS detector at the LHC is presented. This analysis uses 139 fb-1 of proton-proton collision data at s=13 TeV recorded in 2015-2018. The search employs techniques for reconstructing vertices of LLPs decaying to jets in the muon spectrometer displaced between 3 and 14 m with respect to

Purpose: To investigate whether the reduced retinal function and morphological retinal changes previously demonstrated in ABCA4 carriers had remained stationary or had deteriorated over time at 5-year follow-up to further explore if carriers of an autosomal recessive trait also express a weak phenotype, although this is not expected for an autosomal recessive disorder. Methods: Thirteen ABCA4 carr

Introduction: Plasma biomarkers will likely revolutionize the diagnostic work-up of Alzheimer's disease (AD) globally. Before widespread use, we need to determine if confounding factors affect the levels of these biomarkers, and their clinical utility. Methods: Participants with plasma and CSF biomarkers, creatinine, body mass index (BMI), and medical history data were included (BioFINDER-1: n = 7

Humans have an impressive ability to communicate precise social intentions and desires with their voice - through vocal attitudes. Previous studies have shown how isolated acoustic features such as pitch can convey social attitudes, but have mostly worked with single attitudes and have not controlled for inter-speaker variability. Thus, the vocal behaviours used to produce social attitudes remain

Several observables sensitive to the fragmentation of b quarks into b hadrons are measured using 36 fb-1 of s=13 TeV proton-proton collision data collected with the ATLAS detector at the LHC. Jets containing b hadrons are obtained from a sample of dileptonic tt¯ events, and the associated set of charged-particle tracks is separated into those from the primary pp interaction vertex and those from t

Raman spectroscopy is a powerful technique that allows for simultaneous measurements of multiple species; however, it suffers from low signal intensity and, in diagnostics of ammonia (NH3) combustion, strong flame fluorescence. The current work re-introduces a multipass setup to perform enhanced quantitative Raman spectroscopy measurements of major species and nitric oxide (NO) in a premixed lamin

A large share of growth in the sharing or platform economy is driven by peer-to-peer (P2P) accommodation providers such as Airbnb. The literature argues for both positive and negative socio-cultural, economic and environmental impacts emanating from the tourism and hospitality businesses and value chains that are dependent on AirBnB and other online platforms. These impacts are felt in terms of co

With air-photonics THz platform, we investigated photo-induced carrier dynamics of single and multilayer 2D perovskite single crystals. Interesting novel features and physics are revealed with effective conductivity spectrum up to 12 THz and 40-fs time resolution.

A novel synthesizing procedure is introduced and employed to extract locally-optimal cloaking devices. Their performance is compared with fundamental bounds found using a convex optimization approach. The optimization method is based on a method-of-moments paradigm utilizing rank-1 updates of the structure iteratively performed based on a greedy algorithm. This approach produces locally optimal sh

Antibiotikaresistens innebär att bakterier blir motståndskraftiga mot antibiotika. Det är ett växande globalt problem eftersom möjligheten att behandla och bota infektioner minskar i takt med att antibiotikaresistensen ökar. En av orsakerna till resistensproblematiken är felaktig användning av antibiotika vid djuruppfödning. Exempelvis ges antibiotika inte endast vid behov utan i tillväxtbefrämjan

Previous research shows that wars contributed to the expansion of state revenues in the Early Modern period and in the twentieth century. There are, however, few cross-national studies on the long nineteenth century. Using new unbalanced panel data on wars and public revenues from 1816 to 1913 for 27 American and European countries, this article provides new evidence that military conflicts very r

The human macula is a highly specialized retinal region with pit-like morphology and rich in cones. How Müller cells, the principal glial cell type in the retina, are adapted to this environment is still poorly understood. We compared proteomic data from cone- and rod-rich retinae from human and mice and identified different expression profiles of cone- and rod-associated Müller cells that converg

Nucleus is at the center stage of cellular drama orchestrated in the life of a cell and the nucleoplasm is surrounded by a double membranous compartment constituting the Nuclear membrane/envelope (NE) that separates it from the cytoplasm in nucleated cells. The initial understanding of the NE was that of a border security entity between the nucleus and the cytoplasm, separating gene regulation and

Obstetric records of hospital births of children present in the Scanian Economic Demographic Database. The records contain information on gestational age, birthweight, and other indicators of health of the child, as well as information on maternal health.

Meta-analysis is a statistical method used in evidence synthesis for combining, analyzing and summarizing studies that have the same target endpoint and aims to derive a pooled quantitative estimate using fixed and random effects models or network models. Differences among included studies depend on variations in target populations (ie, heterogeneity) and variations in study quality due to study d

Particle size can be an important variable to know in many different areas, be it smoke simulations, toxicity of materials or tests of face masks. Fires in a reduced oxygen environment can occur for ventilation-controlled fires or in areas with artificially lowered oxygen levels. The effects of lower concentrations of oxygen on heat release rate, smoke production etc. has been studied, but any eff

We study the effects of counterfactual teacher-to-classroom assignments on average student achievement in U.S. elementary and middle schools. We use the Measures of Effective Teaching (MET) experiment to semiparametrically identify the average reallocation effects (AREs) of such assignments. Our identification strategy exploits the random assignment of teachers to classrooms in MET schools. To acc

Poly(xanthene)s (PXs) carrying trimethyl ammonium, methylpiperidinium and quinuclidinium cations were synthesized and studied as a new class of anion exchange membranes (AEMs). The polymers were prepared in a superacid-mediated polyhydroxyalkylation involving 4,4’-biphenol and 1-bromo-3-(trifluoroacetylphenyl)-propane, followed by quaternization reactions with the corresponding amines. The archite
