A search for decays of the Higgs boson into a Z boson and a light resonance, with a mass of 0.5–3.5 GeV, is performed using the full 140 fb−1 dataset of 13 TeV proton–proton collisions recorded by the ATLAS detector during LHC Run 2. Leptonic decays of the Z boson and hadronic decays of the light resonance are considered. The resonance can be interpreted as a J/ψ or ηc meson, an axion-like particl

Why do some mediation strategies towards spoilers in internal conflicts fail, while others succeed? The aim of this thesis is to examine how the mediation strategies towards spoilers affect the outcome of internal conflicts through the analysis of the mediator and spoiler behaviour. The analytical point of departure is the explanatory behavioural variables: spoiler type, spoiler locus, mediator im

The ATLAS Inner Detector is a composite tracking system consisting of silicon pixels, silicon strips and straw tubes in a 2 T magnetic field. Its installation was completed in August 2008 and the detector took part in data-taking with single LHC beams and cosmic rays. The initial detector operation, hardware commissioning and in-situ calibrations are described. Tracking performance has been measur

The fundamental limits of the gain and efficiency of an antenna are explored. The antenna is confined in a sphere and all of the currents are assumed to run in a material with a conductivity that is a function of the radial coordinate. The analysis is based on the expansion of the electromagnetic fields in terms of vector spherical harmonics. Explicit expressions for the limits of gain and efficie

Anorthoscopic vision: Designing and Sensing the Future Tom O’Dell As a means of thinking about the future and issues of uncertainty, I would like to take my point of departure in a project I completed a few years ago (O’Dell 2013) concerning plans to develop a huge particle sciences facility in Lund, called the European Spallation Source (ESS). I was the only ethnologist working with a team of 1

Background: Total tau (tTau) and phosphorylated 181P tau (pTau) are supportive diagnostic cerebrospinal fluid (CSF) biomarkers for Alzheimer's disease. Manual CSF tau assays are limited by lot-to-lot and between-laboratory variability and long incubation/turnaround times. Elecsys® Total-Tau CSF and Phospho-Tau (181P) CSF immunoassays were developed for fully automated cobas e analyzers, allowing b

Intersectional discrimination against people on the move underpins inadequate responses to COVID-19. The right to enjoy the benefits of scientific progress and its applications clearly demands substantive racial equality when designing economic and public health measures to address the pandemic.
