In this paper, we investigate how adaptive time-integration strategies can be effectively combined with parallel-in-time numerical methods for solving systems of ordinary differential equations. Our focus is particularly on their influence on tolerance proportionality. We examine various grid-refinement strategies within the multigrid reduction-in-time (MGRIT) framework. Our results show that a si
This thesis examines how parody and satire are used in contemporary Americananimated television series. Through critical textual analysis, five television shows are examined. These are Archer, BoJack Horseman, My Little Pony: Friendship is Magic, Rick and Morty, and South Park. The study offers theoretical background and discussion on key concepts like parody, satire, comedy, animation, television
In an era where online interactions increasingly shape social dynamics, the pervasive issue of cyberbullying poses a significant threat to the well-being of individuals, particularly among vulnerable groups. Despite extensive research on text-based cyberbullying detection, the rise of visual content on social media platforms necessitates new approaches to address cyberbullying using images. This d
Background: Ex-vivo perfusion of donor hearts is gaining importance in minimizing ischemia-reperfusion injury during heart transplantation. The Non-Ischemic Heart Preservation (NIHP) device, developed in 2016, has shown promising results in pilot studies. This study aims to compare the mid-term follow-up outcomes of NIHP with traditional Static Cold Storage (SCS) in heart transplantation. Methods:
We study the first-order phase transitions and the emerging stochastic gravitational wave spectrum in a minimal leptoquark extension of the Standard Model that explains active neutrino oscillation data, while satisfying current flavor physics constraints. This model exhibits diverse phase transition patterns, including color symmetry-breaking scenarios in the early Universe. Strong correlations be
Let (Formula presented.) be a (Formula presented.) -adic analytic pro- (Formula presented.) group of dimension (Formula presented.), with lower (Formula presented.) -series (Formula presented.). We produce an approximate series which descends regularly in strata and whose terms deviate from (Formula presented.) in a uniformly bounded way. This brings to light a new set of rational invariants (Form
In this paper we present a method for line segment detection in images, based on a semi-supervised framework. Leveraging the use of a consistency loss based on differently augmented and perturbed unlabeled images with a small amount of labeled data, we show comparable results to fully supervised methods. This opens up application scenarios where annotation is difficult or expensive, and for domain
In this paper, we present a system for drone detection and positioning. The approach uses a system composed of an audio detection rig with a set of microphones, a set of fixed cameras with a large combined field of view and a Pan-TiltZoom camera. We present how this system can be defined in an efficient and modular way with a number of parallel sensing modules. The focus of this work is the audio
This article examines the fire and rescue services sector in Sweden in the period 1986–2021, and explains the timing of bureaucratic reforms using the Multiple Streams Framework (MSF). In this study, we insert institutions in MSF by employing a two-level analysis; we highlight the interactions among experts acting as policy entrepreneurs over time and during a large window of opportunity, and we s
The imperative to reduce greenhouse gas emissions is intensifying in various sectors. This trend is evident in the non-road mobile machinery sectors, including agricultural and construction equipment, where the electrification of machinery is emerging as a key development. However, battery-electric non-road mobile machinery systems face challenges, primarily due to the limited energy storage capac
Context. Globular clusters exhibit star-to-star chemical variations that are traceable through both photometric and spectroscopic data. While UV photometry and light-elements such as Na and O are commonly used for this purpose, the optical V versus (V-I) color magnitude diagram (CMD) is often assumed to be relatively unaffected by such inhomogeneities and is used to derive basic cluster parameters
Background: Type 2 diabetes (T2D) is associated with increased risk of complications after breast cancer surgery. This study investigated systemic and surgical-site postoperative complications and the risk of early and late breast cancer recurrence and mortality, overall, and according to T2D status. Methods: From the Danish Breast Cancer Group (DBCG) and Danish registries, a cohort of women with
Context. The young β Pictoris system has been monitored with high-resolution optical spectrographs for decades. These observations have revealed strongly variable stochastic absorption in the Ca II H&K lines attributed to infalling cometary bodies. Aims. Since 2003, over 9000 HARPS observations of β Pictoris have been taken, and many of these have not yet been used for exocomet studies. We aim
Large-scale genomic resources can place genetic variation into an ecologically informed context. To advance our understanding of the population genetics of the fruit fly Drosophila melanogaster, we present an expanded release of the community-generated population genomics resource Drosophila Evolution over Space and Time (DEST 2.0; https://dest.bio/). This release includes 530 high-quality pooled
In historical the Netherlands, child mortality was distributed unequally between families and this inequality persisted across generations. Using family reconstitution data for the province of Zeeland (LINKS) containing over 200,000 children born 1835–1914, I show that mortality was higher among children under age 5 whose parents lost siblings under age 5. Intergenerational persistence was stronge
Introduction: Wildfires pose escalating risks to communities at the wildland--urban interface, often necessitating extensive evacuations. This thesis explores how driving behaviour during wildfire evacuations differs from routine conditions and how these differences can be modelled to improve traffic simulations, thereby supporting more informed planning and response decisions by authorities.Objec
Background Olfactory dysfunction is a common non-motor symptom in Parkinson’s disease (PD). The objective was to evaluate the association between olfaction in PD with cross-sectional and longitudinal assessments of clinical variables and novel cerebrospinal fluid (CSF) markers. Methods Patients with PD and baseline olfactory function assessed using the Brief Smell Identification Test (B-SIT) were
Cytolysin A (ClyA) is a pore-forming protein from a strongly silenced gene in non-pathogenic Escherichia coli, including typical commensal isolates in the intestinal microbiome of healthy mammalian hosts. Upon overproduction, ClyA-expressing bacteria display a cytolytic phenotype. However, it remains unclear whether sublytic amounts of native ClyA play a role in commensal E. coli-host interactions
Neurodegenerative diseases (NDs), such as Alzheimer’s disease (AD), Parkinson’s disease (PD) and frontotemporal dementia (FTD), exhibit distinct yet overlapping pathological mechanisms. Leveraging large-scale plasma proteomics data from the Global Neurodegeneration Proteomics Consortium, we analyzed 10,527 plasma samples (1,936 AD, 525 PD, 163 FTD, 1,638 dementia and 6,265 controls) to identify di
