This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. These structures allow us to model, identify, and classify the processes, enabling parameter estimation for, e.g., identification, localisation, and t
BACKGROUND: Perinatal characteristics are associated with subsequent risk of several chronic diseases. Previous studies regarding endometriosis were based on small samples and retrospective data and were limited by unmeasured confounding bias, leading to conflicting and inconclusive findings. We investigated the associations of maternal and birth characteristics with risk of endometriosis among Sw
Many different types of insects make seasonal migrations over vast distances, typically from one broad geographical region to another, most often involving a latitudinal change in one direction in spring with a reversal of this direction in autumn. However, a small handful of these species instead migrate from an enormous geographical area to a highly specific destination they have never previousl
Recognizing the novel ways in which queer and feminist struggles for change unfold today, Spaces, Bodies, Revolts: Emerging Digital Cultures, Feminist Struggles, and Global Change explores contemporary protest movements and the ambivalent nature of digital cultures carrying them forward. While feminist and LGBTI+ struggles for rights, livability, dignity and safety have always existed, what is new
Intraspecific variation in phenotypic plasticity can affect the ability of populations, and thus species, to respond to environmental changes. However, the prevalence and drivers of such variation are not well known. Most proposed explanations for intraspecific variation in phenotypic plasticity involve mechanisms associated with a population's position within the species' geographic range or the
We report on the shift of energies released during Auger cascades in rare-gas ions, when the ions are not isolated but embedded in a homogeneous cluster. By combining high-resolution electron spectroscopy with multielectron coincidence spectroscopy of small Ar and Xe clusters, we investigate the dependence of Auger electron emission energies on the charge state of the emitting ion in the polarizab
In this paper we consider the classic problem of scattering of waves from perfectly conducting cylinders with piecewise smooth boundaries. The scattering problems are formulated as integral equations and solved using a Nyström scheme, where the corners of the cylinders are efficiently handled by a method referred to as Recursively Compressed Inverse Preconditioning (RCIP). This method has be
In this paper the connection between exogamy and partnership dissolution is analyzed using individual level register data for natives and immigrants moving to Sweden after 1968. We study both formally married and cohabiting unions, from the birth of the first child until dissolution of the partnership. Using event history models we study the impact of type of union (endogamous, exogamous with a na
In the effort to obtain a precise measurement of leptonic CP-violation with the ESSνSB experiment, accurate and fast reconstruction of detector events plays a pivotal role. In this work, we examine the possibility of replacing the currently proposed likelihood-based reconstruction method with an approach based on Graph Neural Networks (GNNs). As the likelihood-based reconstruction method is reason
We study the electronic structure of bulk 1T-TaSe_{2} in the charge-density wave phase at low temperature. Our spatially and angle-resolved photoemission data show insulating areas coexisting with metallic regions characterized by a chiral Fermi surface and moderately correlated quasiparticle bands. Additionally, high-resolution laser angle-resolved photoemission reveals variations in the metallic
The use of Large Language Models (LLMs) such as ChatGPT is a prominent topicin higher education, prompting debate over their educational impact. Studies onthe effect of LLMs on learning in higher education often rely on self-reported data,leaving an opening for complimentary methodologies. This study contributes byanalysing actual course grades as well as ratings by fellow students to investigateh
The Forum Romanum constituted the religious, political, economic and administrative centre of Rome for more than a millennium. During this time it went through several changes. It transformed from a liminal zone in the periphery of the Iron Age settlements into a communal space and sacred ground; later into an arena for political struggle and civic ambition; and finally into a showcase for Imperia
Recovery of plastically deformed metals involves several stages of substructure evolution during which dislocation entanglements and networks become increasingly organized, thereby lowering the stored energy in the material. Central to recovery is the formation and evolution of subgrains, which is also recognized as a recrystallization precursor. In this paper, subgrain coarsening is investigated
In this paper, we have studied the sensitivity of the ESSnuSB far detector to supernova neutrinos. ESSnuSB is a proposed long-baseline neutrino experiment in Sweden, which will use a 538 kt water Cherenkov detector to probe the leptonic phase δCP by studying the second oscillation maximum. However, given the very large detector volume, it will have an excellent sensitivity to supernova neutrinos i
