Search for dark matter produced in association with a Standard Model Higgs boson decaying into b-quarks using the full Run 2 dataset from the ATLAS detector

The production of dark matter in association with Higgs bosons is predicted in several extensions of the Standard Model. An exploration of such scenarios is presented, considering final states with missing transverse momentum and b-tagged jets consistent with a Higgs boson. The analysis uses proton-proton collision data at a centre-of-mass energy of 13 TeV recorded by the ATLAS experiment at the L

Modelling generation Z tourists' social responsibility toward environmentally responsible behaviour : The role of eco-travel cravings

Generation Z (Gen Z) is believed to be more socially and environmentally committed. While environmentally responsible behaviour is crucial to the success of sustainable tourism, little is known about Gen Z's specific environmental behaviours in tourism settings. In this research, the roles of Gen Z's consumption emotions and environmentally friendly behaviour were explored based on cognitive appra

Co-Supervision in Doctoral Studies: What Is It About?

As a part of the LTH Docent Course Spring 2024, this group project interviewed both co-supervisors and doctoral students to understand the roles of co-supervisors in doctoral studies. The study revealed significant variation in co-supervisors' roles across different projects, as confirmed by both students and co-supervisors. The research focused on co-supervisors' activities and levels of engageme

Driving Assistance System with Obstacle Avoidance for Electric Wheelchairs

A system has been developed to convert manual wheelchairs into electric wheelchairs, providing assistance to users through the implemented algorithm, which ensures safe driving and obstacle avoidance. While manual wheelchairs are typically controlled indoors based on user preferences, they do not guarantee safe driving in areas outside the user’s field of vision. The proposed model utilizes the dy

Sod1-deficient cells are impaired in formation of the modified nucleosides mcm5s2U and yW in tRNA

Uridine residues present at the wobble position of eukaryotic cytosolic tRNAs often carry a 5-carbamoylmethyl (ncm5), 5-methoxycarbonylmethyl (mcm5), or 5-methoxycarbonylhydroxymethyl (mchm5) side-chain. The presence of these side-chains allows proper pairing with cognate codons and they are particularly important in tRNA species where the U34 residue is also modified with a 2-thio (s2) group. The

A Fast Rotating-Mirror Sounder for Dynamic Millimeter-Wave Channel Characterization

A deep understanding of double-directional wireless channels is imperative for wireless system design. This necessitates the development of precise channel models through channel sounding. Given the dynamic nature of wireless channels, a short measurement time is highly desirable. In this paper, we present and validate a dual-polarized millimeter-wave channel sounder that uses a rotating mirror me

Sixteen Corpses : The First Reburials in the Escorial in 1586 and the Dynastic Dynamics that Made Them Happen

This chapter analyses the Spanish Habsburg crypt at the Escorial and the dynamics that caused it to become increasingly inclusive. Two main dynamics are identif ied: family heads exercising increased authority in mandating burials in the Escorial, including for individuals who had indicated other wishes, like siblings and adult children. And peripheral relatives who previously would not have expec

Nordic influences on Swedish construction law - an example on the value of comparing standard contracts

This article investigates the dependence on standard contracts in Swedish construction law, particularly AB 04 and ABT 06, due to a lack of specialized laws. Comparing them to similar contracts from other Nordic countries demonstrates the value of cross-border legal understanding. A 2018 Swedish Supreme Court judgment highlights this technique, implying that comparative analysis might improve lega

Efficient Absorbance-Based Assay for Rapid Antibiotic Susceptibility Testing of Enterobacterales

It is increasingly important to rapidly receive information on the antimicrobial susceptibility of bacteria due to the rise in antimicrobial resistance worldwide. However, traditional phenotypic methods are time-consuming. Thus, the objective of this study was to develop a rapid assay that can detect antibiotic-resistant bacterial isolates phenotypically in less than 2 h. The microplate assay used

The Growth of Food Aid in Sweden – How Demand and Supply are Transforming Charitable Organisations

The purpose of this article is to describe and analyse the growth in food aid in Sweden, and how it affects the non-profit organisations providing it. The particular type of food aid in focus is large-scale collaborations between charitable non-profit organisations and the food industry, through which food surplus is turned into food aid for people in food insecurity. The first examples of such fo

China’s Crisis Governance and Evolving State-Society Relations during the COVID-19 Pandemic

Existing studies on China’s COVID-19 response have gravitated to a macro-level,formal institutional analysis, focusing either on the effectiveness of the policy in early stage virus containment or on the growing negative impacts of COVID policy practices on China’s socio-political landscape at the late stage. Using serial interviewsaccompanied by online observations and documents, this thesis redi

Measurement of jet substructure in boosted Formula Presented events with the ATLAS detector using Formula Presented of 13 TeV Formula Presented collisions

Measurements of the substructure of top-quark jets are presented, using Formula Presented of 13 TeV Formula Presented collision data recorded with the ATLAS detector at the LHC. Top-quark jets reconstructed with the anti-Formula Presented algorithm with a radius parameter Formula Presented are selected in top-quark pair (Formula Presented) events where one top quark decays semileptonically and the

Search for magnetic monopoles and stable particles with high electric charges in (Formula presented.) TeV pp collisions with the ATLAS detector

We present a search for magnetic monopoles and high-electric-charge objects using LHC Run (Formula presented.) TeV proton-proton collisions recorded by the ATLAS detector. A total integrated luminosity of 138 fb−1 was collected by a specialized trigger. No highly ionizing particle candidate was observed. Considering the Drell-Yan and photon-fusion pair production mechanisms as benchmark models, cr

Performance of the ATLAS forward proton Time-of-Flight detector in Run 2

We present performance studies of the Time-of-Flight (ToF) subdetector of the ATLAS Forward Proton (AFP) detector at the LHC. Efficiencies and resolutions are measured using high-statistics data samples collected at low and moderate pile-up in 2017, the first year when the detectors were installed on both sides of the interaction region. While low efficiencies are observed, of the order of a few p

Rethinking (Human) bodies in HRI : Embodied interactions every day

Significant amounts of HRI research effort are spent on the design/evaluation of robot bodies. Critical discussion and debates concerning the way bodies are treated and considered within HRI have tended to focus on the implications of designing/interacting with highly anthropomorphic robots, yet drawing attention away from the human body in HRI, particularly in the context of everyday interactions
