We couple to group field theory (GFT) a scalar field that encodes the entanglement between manifold sites. The scalar field provides a relational clock that enables the derivation of the Hamiltonian of the system from the GFT action. Inspecting the Hamiltonian, we show that a theory of emergent gravity arises, and that this can be recast according to the Ashtekar’s formulation of general relativit
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
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
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
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
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 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
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
Publikationen sammanställer kunskap relevant för att utveckla och praktisera ledarskap i aktörsgemensamma sammanhang. Innehållet täcker centrala begrepp och beskriver olika organisatoriska miljöer som blir aktuella i samband med kriser och totalförsvar.
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
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 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
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
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
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
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
