Large intelligent surfaces (LIS) extend conventional massive multiple-input multiple-output (MIMO) systems by employing a physically large and dense antenna surface, offering a promising architecture for next-generation wireless communication systems. In practical receivers, oscillator phase noise introduces time-varying phase rotations that cause the effective channel to evolve during a transmiss
2026 års reform av 3:12-reglerna innehåller två ändringar som tillsammans ger upphov till uppsatsens frågeställning. Den första är slopandet av den särskilda skatterättsliga dotterföretagsdefinitionen i 57 kap. 19 a § IL, vilket innebär att koncerndefinitionen i 1 kap. 11 § ABL åter avgör vilka ersättningar som får räknas med i löneunderlaget. Den andra är införandet av ett grundbelopp om fyra inkThe 2026 reform of the 3:12 rules contains two amendments that together give rise to the question examined in this thesis. The abolition of the special tax law definition of a subsidiary in Chapter 57, Section 19 a of the Income Tax Act means that the group definition in Chapter 1, Section 11 of the Companies Act once again determines which remuneration may be included in the wage base. The new ba
Segregation is a pervasive social phenomenon that separates individuals across social settings. Workplaces, as key hubs of the labor market, are not only central to economic outcomes but also potential sites for cross-cutting social ties. Yet workplace segregation can exacerbate inequality and weaken social cohesion. Existing research has largely examined highly visible categories such as rac
Do negative income shocks increase conflict risk? I study the relationship between desert locust infestations and conflict in 26 African countries. Combining geolocalized data on locust swarms and bands with information on conflict events, I construct two panel datasets at spatial resolutions 0.5◦ × 0.5◦ and 0.1◦ × 0.1◦, covering the years 1997–2017. I find a negative relationship between locust i
The green energy transition and circular economy is dependent on a growing and more efficient metal waste stream to address the future increasing demand for metal resources. The drive for increased metal recycling can conflict with occupational health and safety, and the metal recycling industry exposes workers to hazards that can lead to potential health effects such as respiratory, cardiovascula
Safety leadership is considered to be an important factor for safety culture and safety performance. Leaders doubtlessly influence overall safety work and performance; thus, it is important to increase the knowledge what safety leadership entails in a nuclear power production setting. Safety leadership is not a standalone concept, but it exists in an organizational context and is related to systemSafety leadership is considered to be an important factor for safety culture and safety performance.

Matrix cooling is an internal cooling concept for gas turbine blades that combines structural reinforcement with enhanced heat transfer through a rib-crossing lattice geometry. The repeated flow redirection generates strong shear layers, impingement, and vortical structures that significantly influence turbulent transport and heat transfer. This study presents a numerical investigation of turbulen
Sex chromosome evolution is characterized by Y/W degeneration and its consequences for selection on X/Z-linked recessive mutations in the heterogametic sex, yet how functional constraints modulate the evolutionary dynamics of Z–W gametologs remains poorly resolved. We addressed this question in larks (Alaudidae), a lineage carrying enlarged neo-sex chromosomes with multiple evolutionary strata for
Sex chromosomes are central to many ecological and evolutionary processes. Evidence has accumulated that sex chromosome systems vary extensively in age, turnover and transitions, motivating renewed efforts to study the diversity of sex chromosome systems across the tree of life. However, successful genomic detection of sex chromosomes depends on several factors, including the size and divergence t
Converting conventional cropping systems from annual to perennial has been proposed as a strategy to enhance soil organic carbon (SOC) input and storage due to larger root systems and reduced soil disturbance. The mechanisms underlying SOC sequestration are fundamentally mediated by soil microorganisms, which play dual roles: they assimilate labile plant-derived C into microbial biomass that can s
Electrophysiological approaches are widely used to characterize insecticide target sites, whereas behavioral symptoms associated with different modes of action remain less quantitatively explored. Here, we developed a computer vision–based framework to quantify insecticide-induced behavioral responses in the cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae).

ObjectiveFoetal-neonatal alloimmune thrombocytopaenia (FNAIT) is a rare disease, most commonly caused by maternal alloantibodies to human platelet antigen (HPA)-1a that can result in severe bleeding. The present study was designed to determine the frequency of higher risk for HPA-1a alloimmunisation and development of FNAIT among a racially and ethnically diverse cohort of pregnant women.DesignLon
I den här studien utvärderar vi geologiska arkiv och ett flertal geologiska metoder för att identifiera och datera historiska stormflodshändelser längs Hallands kust. Vi har också undersökt en lokal vid Löderup i Skåne som påverkats av en modern stormflod under stormen Babet hösten 2023. Genom fjärranalysbaserat platsurval, fältarbete samt olika laboratorieanalyser inklusive dateringsmetoder testaThis study evaluates geological archives and a suite of proxy methods to identify and date past storm-surge events along the Halland coast, southwest Sweden, with a modern analogue site at Löderup in Scania. Using GIS-based site selection, targeted fieldwork and laboratory analyses including dating methods, we tested which coastal settings and methods best record overwash deposits and whether the
The rate of energy turnover in an animal, metabolic rate, is fundamental to life and determines the energy available for growth, reproduction, and survival. Thus, metabolic rate has been proposed as a mechanism linking physiology to broader ecological patterns. Numerous adaptive frameworks have been proposed to explain how selection acts on metabolic rate, how it relates to life histories, and the
