Land cover governs the biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene temperature conundrum, a widely studied mismatch between simulated and reconstructed temperatures. Prog

This paper argues that conventional blame practices fall short of capturing the complexity of moral experiences, neglecting power dynamics and discriminatory social practices. It is evident that robots, embodying roles linked to specific social groups, pose a risk of reinforcing stereotypes of how these groups behave or should behave, so they set a normative and descriptive standard. In addition,

Introduction: Although climate change has been consistently identified as one of the greatest threats to humans, many clinicians do not feel prepared to address climate change with patients and medical school curricula still have very little coverage of its health consequences. At the same time, health care providers have been shown to be trusted voices and are therefore well suited to help build

A two-level three-factor factorial design experiment was conducted to study the influences of three critical specimen preparation parameters on the measurement results of bitumen by a dynamic shear rheometer (DSR). The investigated factors were (1) the pre-heating temperature (HT) for manufacturing the specimen, (2) the bonding temperature (BT) onto the rheometer, and (3) the trimming (Trim) opera

This paper introduces a novel method for solving the single-source localization problem, specifically addressing the case of trilateration. We formulate the problem as a weighted least-squares problem in the squared distances and demonstrate how suitable weights are chosen to accommodate different noise distributions. By transforming this formulation into an eigenvalue problem, we leverage existin

The only way to combat the depletion of resources and climate crisis is to reduceour dependence on fossil fuels. Renewable sources, such as wind and solar energy,are increasingly used to meet our ever-growing energy demands; however, they areintermittent. One promising solution to the power crisis in the world is fuel cells,which, unlike the combustion engine, can operate on renewable fuels such a

The rheological properties of bituminous binders tested with a dynamic shear rheometer (DSR) as a function of loading time and temperature can more accurately represent real road situations with rising traffic loads and densities combined with climatic change. This method is more effective than traditional methods such as measuring the softening point and penetration. Complex shear modulus and pha

Glioblastoma (GBM) and ischemic stroke represent two challenging brain pathologies which still lack an optimal therapeutic strategy. Central to these diseases are pericytes, mural cells that regulate blood-brain barrier (BBB) integrity, vascular stability, and immune responses. However, the diseasespecific alterations in pericytes that contribute to GBM progression and their influence on the posts

Amyloids are elongated supramolecular protein self-assemblies. Their formation is a non-covalent assembly process and as such is fully reversible. Amyloid formation is associated with several neurodegenerative diseases, and the reversibility is key to maintaining the healthy state. Reversibility is also key to the performance of fibril-based biomaterials and functional amyloids. The reversibility

Transmission electron microscopy (TEM) is an atomically resolved technique that allows for in depth analysis of the properties of materials by irradiating a thin sample with high energy electrons and detecting the signal imparted on, and generated by, the electron beam as it passes through. However, due to the strong interaction between electrons and matter, the sample will not remain unperturbed

Spectrum imaging with energy-dispersive X-ray spectroscopy (EDS) has become ubiquitous in material characterization using electron microscopy. Multivariate statistical methods, commonly principal component analysis (PCA), are often used to aid analysis of the resulting multidimensional datasets; PCA can provide denoising prior to further analysis or grouping of pixels into distinct phases with sim

Children’s understanding of death, bereavement and grief develop through socialisation where picture books also may play a role. The study explores how children’s picture books published in China (2010–2024), communicated themes of death, bereavement and grief. A systematic search identified 321 relevant books, of which 47 met the inclusion criteria and were analysed using both descriptive and a B

Switches and crossings are prone to failure thus making them drivers of unreliability in the operation of many railway systems. Unreliability is directly linked to punctuality which continues to limit, among other factors, the uptake of railways as a sustainable mode of transport. To fix this issue, there is a need for a better understanding of the contribution of railway sub-systems to train dela

Understanding the impact of various factors on train arrival delays is a prerequisite for effective railway traffic operating control and management. Existing studies model the train delay prediction problems using a single, generic equation, restricting their capability in accounting for heterogeneous impacts of spatiotemporal factors on arrival delays as the train travels along its route. The pa

This research project explores how theatre can contribute to democratic engagement. The starting point was artistic probes investigating aspects of democracy: participation, deliberation and inclusion. The probes resulted in three productions presented at theatre institutions in Sweden. In Skapa Demokrati (Creating Democracy), participation was promoted by encouraging the audience members to creat

This article focuses on the early history of Northwestern European opinion polling (1940s–1950s), specifically the cases of the Netherlands and Sweden. The evolution of opinion polling and its influence on post-war politics and society should be understood in light of processes of international transfer and entanglement. The Dutch-Swedish comparison brings into focus the ways in which the national

The excursion distribution of stochastic processes is important in many applications and is an important object in probability theory. The excursion distributions are defined as the time between a u-level up-crossing and the following down-crossing of the same level. While the notion of the excursion distribution might be intuitive, the general problem of describing it is not. Finding the excursio
