Balancing selection is a potentially important factor in the maintenance of genetic variation for fitness and, alongside recessive deleterious mutations, the genetic basis of inbreeding depression. Classic population genetics theory predicts that inbreeding restricts the range of conditions leading to balancing selection. For example, in models of heterozygote advantage, the classic theory shows t
I uppsatsen undersöker vi hur ett system styrt av Klein-Gordon-ekvationen beter sig under en punktpåverkan. Detta är den enklaste typen av påverkan och med hjälp av denna kunskap kan man dra slutsatser om systemets beteende för mer generalla fall av påverkan. Kvantfysiken beskriver de mest fundamentala byggstenarna av vårt universum, subatomära partiklar. Dessa är, som namnet tyder på, mindre än This paper explores the Klein-Gordon equation, a relativistic wave equation. More specifically, it studies the free form of the equation, where the potential is set to zero. The partial differential equation, together with initial conditions, forms an initial value problem. The first goal of the paper is to derive the Green's function for the problem. This is done in several ways, using spectr
The European Union's climate strategy emphasises energy democracy, encouraging citizens to participate actively in energy production and consumption as part of the transition to climate neutrality by 2050. This chapter explores the role of energy communities (ECs) in advancing energy democracy, particularly within Sweden's centralised energy system. ECs offer citizens a pathway to collective owner
Supplemental Instruction has worked very well in various settings all over the world. It should be of interest to see if SI works at earlier stages than tertiary education. There are examples of successful SI programs at upper secondary schools, but no reports from lower secondary schools. This study evaluates a pilot SI program in a 7th and a 9th grade class in a socially challenged area with reg
Denna avhandling undersöker hur legitimiteten i Europeiska Unionens (EU) stöd för LGBTIQ-jämlikhet bör bedömas och hävdas mot bakgrund av ytterhögerns främjande av en konkurrerande vision för europeiskt samarbete som är rotad i anti-genderpolitik. Med utgångspunkt i agonistisk och queer-teori konceptualiseras EU:s stöd för LGBTIQ-jämlikhet som ett försök att skapa en europeisk pro-LGBTIQ-konsensusThis dissertation examines how the legitimacy of the European Union’s (EU) support for LGBTIQ equality should be assessed and asserted amid the far right’s promotion of a rival vision for European cooperation rooted in anti-gender politics. Drawing on agonistic and queer theory, the EU’s support for LGBTIQ equality is conceptualised as an effort to forge a European pro-LGBTIQ consensus, termed sex

Pediatric randomized controlled trials (RCTs) inform decisions concerning the choice of interventions in children and adolescents. To enable the implementation of effective interventions, RCT reports need to provide adequate details on the elements, infrastructure, and delivery of these interventions. Using the 12-item Template for the Intervention Description and Replication (TIDieR) framework, a
INTRODUCTION: Patients with non-small cell lung cancer (NSCLC) faced an elevated risk for severe COVID-19 outcomes and were prioritized for early vaccination. However, immune responses to SARS-CoV-2 vaccines remain poorly characterized in this group, especially in patients receiving immune checkpoint inhibitor PD-1/PDL-1 (ICI) therapy.MATERIALS AND METHODS: In this prospective observational study,
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with increased risk of stroke, heart failure, and mortality. One of the systems which AF is influenced by is the autonomic nervous system (ANS), which regulates involuntary functions such as heart rate. Environmental stressors, such as air pollution, may also affect these physiological systems and contribute
The Kunming-Montréal Global Biodiversity Framework, adopted at COP15, establishes a clear mandate to mobilize funding from diverse sources to address the escalating biodiversity crisis. Despite growing awareness and commitment to biodiversity conservation, a substantial financing gap persists, hindering efforts to protect and restore ecosystems effectively. This chapter provides an in-depth examin
Arid mountainous regions are vulnerable to extreme hydrological events such as floods and droughts. Providing accurate and continuous rainfall records with no gaps is crucial for effective flood mitigation and water resource management in these and downstream areas. Satellite data and geospatial interpolation can be employed for this purpose and to provide continuous data series. However, it is es
Rent-seeking does not occur in an empty room, rent-seekers act within an institutional framework. Neither does this framework exist in an empty room, it rests on laws and regulations that are the result of action taken by a variety of agents. When one agent takes steps to change the framework to benefit herself, she will also change the conditions for other agents, some for the better and some for
The global steel industry accounts for 8–10 % of global CO2 emissions and requires deep decarbonisation for achieving the targets set in the Paris Agreement. However, no low-emission primary steel production technology has yet been commercially feasible or deployed. Through analysing revisions and additions of European Union climate policy, we show that green hydrogen-based steelmaking in competitThe global steel industry accounts for 8–10 % of global CO2 emissions and requires deep decarbonisation for achieving the targets set in the Paris Agreement.

Semi-visible jets, with a significant contribution to the event's missing transverse momentum, can arise in strongly interacting dark sectors. This results in an event topology where one of the jets can be aligned with the direction of the missing transverse momentum. The first search for semi-visible jets produced via a t-channel mediator exchange is presented. The analysis uses proton-proton col
A search for nonresonant Higgs boson pair production in the bb¯γγ final state is performed using 140 fb−1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. This analysis supersedes and expands upon the previous nonresonant ATLAS results in this final state based on the same data sample. The analysis strategy is optimi
This letter presents a search for narrow, high-mass resonances in the Zγ final state with the Z boson decaying into a pair of electrons or muons. The s=13 TeV pp collision data were recorded by the ATLAS detector at the CERN Large Hadron Collider and have an integrated luminosity of 140 fb−1. The data are found to be in agreement with the Standard Model background expectation. Upper limits are set
