This paper presents a search for a new Z′ resonance decaying into a pair of dark quarks which hadronise into dark hadrons before promptly decaying back as Standard Model particles. This analysis is based on proton-proton collision data recorded at s = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb−1. After sele

Groundwater, as a vital water resource in arid and semi-arid regions, plays a crucial role in sustaining human livelihoods, agriculture, and industry. Over recent decades, these areas have witnessed rapid groundwater depletion, raising concerns about resource sustainability. This research provides a comprehensive analysis of the factors contributing to the decline in groundwater levels (GWL) withi

The problem of approximate joint eigen-decomposition of a collection of matrices arises in a number of diverse engineering and signal processing problems. This problem is usually cast as an optimization problem, and it is the main goal of this publication to provide a theoretical study of the corresponding objective-functional. As our main result, we prove that this functional tends to infinity in

Background/Objectives: Older patients are more susceptible to the process of understanding and retrieving information. To provide adequate preoperative information, reduce their vulnerability and anxiety, and thereby facilitate pre-, intra-, and postoperative care, the adoption of new information technologies is essential. This study aimed to explore elderly patients' experiences and perceptions o

Normally, the measurement limit for luminescence analysis of quartz is 50-70 ka with the most widely used single aliquot regeneration (SAR) protocol, consequently, the dating of MIS 3 and MIS 4 samples or older is problematic using quartz. However, recent studies propose that the sensitivity-corrected multiple aliquot regenerative dose (SMAR) measurement technique has the potential to extend the d

The introduction of “water-in-salt” electrolyte (WiSE) concept opens a new horizon to aqueous electrochemistry that is benefited from the formation of a solid-electrolyte interphase (SEI). However, such SEI still faces multiple challenges, including dissolution, mechanical damaging, and incessant reforming, which result in poor cycling stability. Here, we report a polymeric additive, polyacrylamid

Multi-hazard events, though infrequent and rare, are responsible for a substantial portion of global economic losses. This book chapter investigates the complexities of multi-hazard events and explores the design challenges and methodologies in multi-hazard risk assessment and structural resilience for wooden structures. Special attention is given to the interaction between earthquakes, fires, and

Conservation grazing is widely used to manage open ecosystems, but inconsistent definitions and inadequate reporting of grazing patterns hinder effective communication among researchers, practitioners and policymakers, limiting the understanding and success of conservation grazing regimes. We demonstrate detailed measurement of the grazing pattern (comprising timing, intensity, duration and freque

Rationale: Proper sedation for neonates undergoing uncomfortable procedures may reduce stress and prevent complications. Midazolam is a short-acting benzodiazepine that is used in neonatal intensive care units. This is an update of a Cochrane review first published in 2003. Objectives: To assess the benefits and harms of midazolam – compared with placebo, other pharmacological interventions, and n

In this 5th version of the European LeukemiaNet guidance for adult patients, there are important changes in several areas of management based on evidence available since 2020, including the World Health Organisation’s reclassification of CML as a biphasic disease. Previous advice to switch the tyrosine kinase inhibitor (TKI) on failure of molecular milestones, is modified to better account for ind

The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 – 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel. This premium

Whether executed as full-scale war or acts short of war, acts of aggression have consistently shaped the history of humankind. Acts of aggression would not occur if it were not for the involvement of individuals. The historical development of aggression in international law has seen a shift from a regime solely focusing on the unlawfulness of the action by States, to include the unlawfulness of th

A search for the K+ → π+X decay, where X is a long-lived feebly interacting particle, is performed through an interpretation of the K+ → π+νν¯ analysis of data collected in 2017 by the NA62 experiment at CERN. Two ranges of X masses, 0–110 MeV/c2 and 154–260 MeV/c2, and lifetimes above 100 ps are considered. The limits set on the branching ratio, BR(K+ → π+X), are competitive with previously repor

The luminosity monitor LUCID (LUminosity Cherenkov Integrating Detector) employed in the ATLAS experiment at the LHC had to be upgraded for the second run of LHC (Run 2) that started in spring 2015. The increased energy of the proton beams and the higher luminosity implied that the Photomultipliers of the original LUCID detector had to be replaced for Run 2 to cope with the more demanding conditio
