This paper presents measurements of top-antitop quark pair (tt¯) production in association with additional b-jets. The analysis utilises 140 fb−1 of proton–proton collision data collected with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13 TeV. Fiducial cross-sections are extracted in a final state featuring one electron and one muon, with at least three or four b

In parallel with the exponential increase in extractivism around the world, comes social movements resisting such processes and advocating for alternative forms of development. Extractivism - a mode of accumulation associated with capitalism - is problematic due to the socio-ecological destruction that is embedded in its logics. Opposition to extractivism has intensified and in many instances, wom

We provide a detailed characterization of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99;: 1.13; age: 7.4 Gyr; V mag: 8.25) hosts a transiting sub-Neptune, HD 85426 b, with an orbital period of 16.71 d and a blackbody equilibrium temperature of K. By jointly analysing HARPS-N RVs, TESS, and CHEOPS photometric data and using two different stellar activity mitigat

The intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. In particular, it allows for the investigations of excited, light-flavour vector mesons. The measurement of coherently photoproduced π+π−π+π− final states in ultraperipheral Pb–Pb collisions at sNN=5.02 TeV is presented for the first time. The cross section, d

Processes with τ-leptons in the final state are important for Standard Model measurements and searches for physics beyond the Standard Model. The ATLAS experiment at the Large Hadron Collider observes τ-leptons produced in proton–proton collisions only through their decay products. Data analyses involving hadronically decaying τ-leptons face challenges due to backgrounds from jets misidentified as

Measurements of jet substructure in Pb+Pb collisions provide key insights into the mechanism of jet quenching in the hot and dense QCD medium created in these collisions.This Letter presents a measurement of the suppression of large-radius jets with a radius parameter of R=1.0 and its dependence on the jet substructure. The measurement uses 1.72 nb-1 of Pb+Pb data and 255 pb-1 of pp data, both at

A measurement of the top-quark pole mass mtpole is presented in tt¯ events with an additional jet, tt¯ + 1-jet, produced in pp collisions at s=13 TeV. The data sample, recorded with the ATLAS experiment during Run 2 of the LHC, corresponds to an integrated luminosity of 140 fb−1. Events with one electron and one muon of opposite electric charge in the final state are selected to measure the tt¯ +

This review aims to appraise and summarize the best available evidence from economic evaluations (EEs) of strategies targeting populations prior to a diagnosis of dementia. A comprehensive search was conducted in EMBASE, PubMed, EconLit, Web of Science, Cumulative Index to Nursing and Allied Health (CINAHL), and The NHS Economic Evaluation Database (NHS EED). Publications were dually screened and

To broaden our understanding of bradyarrhythmias and conduction disease, we performed common variant genome-wide association analyses in up to 1.3 million individuals and rare variant burden testing in 460,000 individuals for sinus node dysfunction (SND), distal conduction disease (DCD) and pacemaker (PM) implantation. We identified 13, 31 and 21 common variant loci for SND, DCD and PM, respective

Aims. We aim to observe the transits and occultations of WASP-33 b, which orbits a rapidly rotating δ Scuti pulsator, with the goal of measuring the orbital obliquity via the gravity-darkening effect, and constraining the geometric albedo via the occultation depth. Methods. We observed four transits and four occultations with CHEOPS, and employ a variety of techniques to remove the effects of the

Introduction: Cranioplasty, a surgical procedure to restore skull integrity and aesthetic contour following decompressive craniectomy, poses challenges in material selection and timing, driven by the lack of guidelines and ongoing regulatory changes. Research question: This study aimed to provide an overview of current cranioplasty practices in Europe, explicitly addressing a potential shift towar

The rapid growth of smart logistics, driven by IoT devices and data-intensive applications, necessitates secure, scalable, and efficient computing frameworks. As the edge-fog-cloud (EFC) paradigm supports real-time data processing, it faces significant security threats and attacks, including privacy risks, data breaches, and unauthorized access. To address these security threats and attacks, block

This study provides a systematic overview of Natural Language Processing (NLP)-based frameworks for Cyber Threat Intelligence (CTI) and the early prediction of cyberattacks in Industry 4.0. As digital transformation accelerates through the integration of IoT, SCADA, and cyber-physical systems, manufacturing environments face an expanding and complex cyber threat landscape. Following the PRISMA 202

This review paper provides a literature review of predictive methods and cybersecurity frameworks essential to safeguard Industry 4.0 manufacturing systems against cyber threats. The review focuses on two key areas: the prediction method and the data used for this prediction. These areas are critical for anticipating cyber threats and implementing effective countermeasures. They underscore the nee

Estimations show that approximately US $23 billion is required for Georgia to meet its climate and environmental targets up to 2030. As the current Nationally Determined Contribution reveals, considering 1990 as a base year, the Republic of Georgia plans a 35% decrease in greenhouse gas emissions by 2030. If the country has financial and technical support, commitment to limit emissions may rise as

Water scarcity is one of the major challenges in semi-arid and arid areas. Drivers for water scarcity include climate change, population growth, economic, and agricultural development. This paper presents a framework for assessing water scarcity under the impact of climate, industry, and socio-economic changes in the Qazvin Plain, Iran. A system dynamics model is developed and calibrated using his

Herein, the grown-into-glass (GIG) CsPbBr3:Ln3+ (Ln = La, Lu) nanocrystals (NCs) are designed and fabricated using an in situ nanocrystallization method. It is shown that a substitution of Pb2+ sites with Ln3+ ions leads to a blueshift of emission position induced by an increase of the bandgap of CsPbBr3. Additionally, the GIG-samples are found to feature excellent photoluminescent (PL) properties

Objective: Cushing's disease (CD) is associated with severely impaired quality of life and shortened life expectancy. Little is known about the socioeconomic consequences of CD and their impact on long-term outcome. Methods: This was a nationwide study including 371 patients with CD (76% women), diagnosed between 1991 and 2018, and 4 matched controls per patient from the background population. Cli

HIP 41378 d is a long-period planet that has only been observed to transit twice, three years apart, with K2. According to stability considerations and a partial detection of the Rossiter- McLaughlin effect, Pd = 278.36 d has been determined to be the most likely orbital period. We targeted HIP 41378 d with CHEOPS at the predicted transit timing based on Pd = 278.36 d, but the observations show no

The reserves, production from mines, supply of aluminium to society and mass fluxes of aluminium in society was assessed using an integrated systems dynamics model (ALUMINIUM) in order to reconstruct the past and investigate potential future scenarios. The investigations for input data show that the mine- able aluminium reserves are large, but finite. We get an average value for the ultimately rec
