A search for neutral long-lived particles (LLPs) decaying in the ATLAS hadronic calorimeter using 140 fb−1 of proton-proton collisions at s = 13 TeV delivered by the LHC is presented. The analysis is composed of three channels. The first targets pair-produced LLPs, where at least one LLP is produced with sufficiently low boost that its decay products can be resolved as separate jets. The second an
This paper presents a search for exotic decays of the Higgs boson into a pair of new pseudoscalar particles, Formula Presented, where one pseudoscalar decays into a Formula Presented-quark pair and the other decays into a Formula Presented-lepton pair, in the mass range Formula Presented. The analysis uses Formula Presented collision data at Formula Presented collected with the ATLAS detector at t
Biological neural network functionality depends on the vast number of connections between nodes, which can be challenging to implement artificially. One radical solution is to replace physical wiring with broadcasting of signals between the artificial neurons. We explore an implementation of this concept by light emitting/receiving III-V semiconductor nanowire neurons in a quasi-2D waveguide. They
Context. Globular clusters exhibit star-to-star chemical variations that are traceable through both photometric and spectroscopic data. While UV photometry and light-elements such as Na and O are commonly used for this purpose, the optical V versus (V-I) color magnitude diagram (CMD) is often assumed to be relatively unaffected by such inhomogeneities and is used to derive basic cluster parameters
Two synchrotron-based studies on 4H-pyran-4-thione, photoelectron spectroscopy and vacuum ultraviolet (VUV) absorption spectra were performed. A highly resolved structure was observed in the photoelectron spectrum (PES), in contrast to an earlier PES study, where little structure was observed. The sequence of ionic states was determined using configuration interaction and coupled cluster methods.
MOTIVATION: Missing data present a pervasive challenge in data analysis, potentially biasing outcomes and undermining conclusions if not addressed properly. Missing data are commonly classified into Missing Completely at Random (MCAR), Missing at Random (MAR), and Missing Not at Random (MNAR). While MCAR poses a minimal risk of data distortion, both MAR and MNAR can seriously affect the results of
Den här rapporten är en del av ett större utvecklingsprojekt och baseras på en serie digitala forskningscirklar för kuratorer inom hälso- och sjukvården som pågick mellan 2020 och 2022. Författarna undersöker, med hjälp av anteckningar från forskningscirklarna och egna erfarenheter som kliniskt verksamma kuratorer, hur deras arbete kan förstås både inom den egna professionen och i samverkan med an
BACKGROUND AND OBJECTIVE: There is no standardized regimen for follow-up after radical cystectomy (RC) for bladder cancer (BC). To address this gap, we conducted a multicenter study involving urologist members from the European Association of Urology (EAU) bladder cancer guideline panels. Our objective was to identify consistent post-RC follow-up strategies and develop a practice-based framework b
New-generation single-layer polytetrafluorethylene (PTFE-) or polyurethane (PU-) covered stent (CS) for the treatment of coronary artery perforation (CAP) during PCI offer high procedural efficacy. To evaluate the comparative long-term safety and efficacy of both devices. This is a multicenter pooled analysis of individual data of patients with CAP undergoing implantation of single-layer PTFE-CS o
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed using the Large Hadron Collider proton-proton collision data sample at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector that correspo
Background and purposeHYPO-RT-PC was the first phase 3 trial showing the long-term efficacy and safety of extremely hypofractionated radiotherapy schedules (ultra-hypofractionation or stereotactic body radiotherapy) compared with standard radiotherapy in localised prostate cancer. We aimed to verify their safety in the context of a clinical trial, by comparing events of potentially radiotherapy-re
The issue of dignity in the context of asylum seekers and their care has been widely discussed from various perspectives. As the rate of asylum-seeking increases, so too does the politics surrounding bare minimum standards. In the process of seeking asylum, individuals are increasingly forced to trade-off access to other rights. This study investigates the normative and human rights gaps in asylum
OBJECTIVE: Glomerular filtration rate (GFR) is generally accepted as the best overall index of renal function. Thus, all potential live kidney donors are tested to ensure that they have a normal GFR before they are eligible for kidney transplantation. The choice of GFR test is very much dependent on local traditions and may include iohexol, 51Cr-EDTA, inulin, or creatinine clearance based on urine
Although the ~200 impact craters known on Earth represent only a small fraction of the craters originally formed, the available data suggest an excess of craters by one order of magnitude, in number, in the interval ca. 470-440 Ma during the Ordovician. Most of these “excess” craters may be related to the breakup of the L-chondrite parent body (LCPB) in the asteroid belt at 465.8 ± 0.3 Ma. This is
Hepatitis B virus (HBV), hepatitis delta virus (HDV), and hepatitis C virus (HCV) remain leading drivers of chronic viral hepatitis, cirrhosis, hepatocellular carcinoma, and liver-related mortality. This ESCMID Study Group for Viral Hepatitis (ESGVH) narrative review summarizes recent advances and expert perspectives in the field. For HBV, emerging biomarkers such as quantitative HBs antigen, HBV
Hepatitis A virus (HAV) remains a preventable cause of acute viral hepatitis, with an estimated 159 million new infections and 39 000 deaths in 2019. Although improved care and hygiene reduced deaths, global incidence rose by approximately 4%, driven by increased symptomatic cases and population growth. The availability of safe and highly immunogenic vaccines and the absence of chronic carriage ma
