The evolution and maintenance of color clines is a classic topic of research in evolutionary ecology. However, studies analyzing the temporal dynamics of such clines are much less frequent, due to the difficulty of obtaining reliable data about past color distributions along environmental gradients. In this article, we describe a case of decades-long temporal stability and directional change in a
Simultaneous rheological, polarized light imaging, and small-angle X-ray scattering experiments (Rheo-PLI-SAXS) are developed, thereby providing unprecedented level of insight into the multiscale orientation of hierarchical systems in simple shear. Notably, it is observed that mesoscale alignment in the flow direction does not develop simultaneously across nano-micro lengthscales in sheared suspen
Stimuli-responsive polymers stand out for their ability to respond to small environmental changes. One of the most representative thermo-sensitive materials is poly(N-isopropyl acrylamide) (PNIPAm), which presents reversible phase transitions close to the human body temperature. However, previous studies observed that the copolymerization of NIPAm with small quantities of different monomers like a
Storm water quality was monitored at four sites in a middle-sized Swedish town. The objective was to compare storm water pollution in the first flush storm water runoff between sites with different traffic intensities within a town. Flow proportional storm water runoff samples were collected. The samples were analyzed for suspended solids, conductivity, total nitrogen, total phosphorus, oil index,

Hybrid CoE Paper 24 Social identities and democratic vulnerabilities: Learning from examples of targeted disinformation Elsa Hedling – April 2025 Hybrid CoE Papers are finalized pieces of analysis on a topic related to hybrid threats, based on one or several research questions. They may be either conceptual analyses or based on a concrete case study with empirical data. The European Centre of Exce
iiAbstractThis thesis examines how women living in a women-only asylum shelter in Austria exercise agency in their daily lives amid institutional regulation, legal uncertainty, and prolonged waiting. It explores how residents organise their daily lives, cope with insecurity, and try to maintain a sense of control within institutional settings and social relationships. Agency is not understood as a
Purpose: Hexokinase 1 (HK1) encodes a ubiquitously expressed hexokinase, which is responsible for the first step of glycolysis, phosphorylation of glucose to glucose-6-phosphate. Both autosomal recessive and dominant variants in this gene have previously been shown to cause human disease, and presently, there are clinical data available for 27 individuals with the monoallelic neurodevelopmental di
Black-box policy optimization is a class of reinforcement learning algorithms that explores and updates the policies at the parameter level. This class of algorithms is widely applied in robotics with movement primitives or non-differentiable policies. Furthermore, these approaches are particularly relevant where exploration at the action level could cause actuator damage or other safety issues. H
DNA sequence and epigenetic information embedded in chromatin must be faithfully duplicated and transmitted to daughter cells during cell division. However, how chromatin assembly and DNA replication are integrated remains unclear. We examined the contribution of the Tousled-like kinases 1 and 2 (TLK1/TLK2) to chromatin assembly and maintenance of replication fork integrity. We show that TLK activ
This work presents the architecture of a prototype software system for image preprocessing and analysis designed to support the guidance of an auxiliary UAV camera. The study begins with an overview of typical UAV onboard elec-tronics, highlighting the electro-optical equipment, which includes a navigation camera and an auxiliary camera with a narrower field of view. Automatic image analysis from
Much scholarship has critiqued the fact that non-governmental organisations (NGOs), as a result of global neoliberalism and consequential state retreat, have become private service providers of children’s protection rights. But how can we explain the situation when neoliberal states also undergo autocratisation and take back service provision from NGOs, while at the same time preserving the privat
Background: Age-related immunosenescence, also known as ‘inflammageing’, may impact the elderly’s ability to mount immune responses against cancers and compromise the effectiveness of immune checkpoint inhibition (ICI). In this context, data on tonsillar cancer (TC), a subset of head and neck squamous cell cancer (HNSCC), are lacking. Aims/objectives: To compare the presence/distribution and featu
Creating thermally stable collagen mimetic peptides (CMPs) is a persistent challenge. Nature leverages covalent crosslinkings to stabilize collagen's signature triple helical tertiary structure and higher-order assemblies. Herein, crosslinkings between levodopa (Dopa) and lysine can covalently stabilize the triple helix in CMPs is demonstrated. Since alkaline conditions catalyze the oxidation of t
Computational analysis of large-scale metagenomics sequencing datasets provides valuable isolate-level taxonomic and functional insights from complex microbial communities. However, the ever-expanding ecosystem of metagenomics-specific methods and file formats makes designing scalable workflows and seamlessly exploring output data increasingly challenging. Although one-click bioinformatics pipelin
This article presents a Luhmann-inspired theory of conflictualization, that is, how objects, relations, and societies come to be defined by the logic of conflict. This article presents a Galtung- and Luhmann-inspired theory of conflictualization, that is, how objects, relations, and societies come to be defined by the logic of conflict. The article conceptualizes conflictualization as a threefold
Sensor degradation poses a significant challenge in autonomous driving. During heavy rainfall, interference from raindrops can adversely affect the quality of LiDAR point clouds, resulting in, for instance, inaccurate point measurements. This, in turn, can potentially lead to safety concerns if autonomous driving systems are not weather-aware, i.e., if they are unable to discern such changes. In t
