Critical infrastructure networks are susceptible to disruptions, and an imbalanced distribution of component importance can significantly amplify their vulnerability to cascading failures or targeted attacks. This study introduces a novel bi-objective optimization framework designed to enhance network resilience by strategically balancing component importance in multi-commodity spatial networks. T
Spatial compositional data with exact zeros arise in many applicationsbut remain challenging for models that often assume strictly positivecomponents. We develop a Bayesian spatial model that combines theDirichlet Composition Distribution, which accommodates exact zeros throughcomponent-specific zero probabilities, with a Gaussian Markov random field representationof the latent compositional field
Climate change is intensifying short-duration rainfall extremes, increasing urban pluvial flood risk across Swedish municipalities. This study develops a novel spatial statistical framework for basement flood risk assessment using Log-Gaussian Cox Process (LGCP) models on metric graphs, applied to 17 years of flood records from Trelleborg, southern Sweden.Unlike conventional approaches that treat
Inclination-dependent grain boundary (GB) energy and shear-coupled motion are studied for and tilt GBs in face-centered cubic materials using three-dimensional (3D) phase field crystal (PFC) simulations. A large dataset spanning misorientation and inclination space is systematically generated to evaluate trends in GB energy and shear-coupling. GB energy variations broadly follow ideal faceting aInclination-dependent grain boundary (GB) energy and shear-coupled motion are studied for [001] and [111] tilt GBs in face-centered cubic materials using three-dimensional (3D) phase field crystal (PFC) simulations.

Urban pluvial flooding is a growing climate-related risk in Nordic cities, where short-duration rainfall extremes interact with aging drainage infrastructure and urban form. This study analyses 17 years (2006–2023) of property-level basement flooding reports from Trelleborg, a coastal municipality in southern Sweden, to identify empirical rainfall thresholds and infrastructural conditions associat
Reconstructions and simulations disagree on whether the Holocene exhibited a long-term cooling or warming signal. Anthropogenic land-use could be an important forcing regionally, but available population-based estimates differ widely. We examine transient Holocene climate model simulations forced with three population-based disturbed-land reconstructions and compare this with a fourth scenario der
Foraminifera are single-celled eukaryotes; most possess a perforated calcite test (shell) that fossilizes in marine sediments. During calcification, morphological features reflect environmental conditions, particularly, foraminiferal porosity is a promising proxy for reconstructing past ocean oxygenation.However, traditional analysis relies on averages from small parts of the shell in 2D slices du
Nanoplastics are increasingly being recognized as a global pollutant. However, relatively few studies report directly measured concentrations of nano- and microplastics in environmental samples, although available data suggest levels of up to 0.5 mg L−1 in lake water, which is surprisingly high. Their degradation in the environment, particularly under UV irradiation, is still poorly understood. He
We must recognize that plastics likely constitute a pervasive background in many environments. Beyond their previously documented risks to ecosystems and human health, plastics may also exert unintended influences on laboratory experiments, potentially distorting experimental outcomes. Here, we demonstrate that ultrasound treatment of commonly used laboratory test tubes releases nanoplastics into
This book proposes the study of norms as a method of explaining human choice and behaviour by introducing a new scientific perspective.The science of norms may here be broadly understood as a social science which includes elements from both the behavioural and legal sciences. It is given that a science of norms is not normative in the sense of prescribing what is right or wrong in various situatio
The study was a non-randomized controlled phase I-II trial to study were to ascertain the safety, feasibility and efficacy of immunotherapy with autologous IFN-γ transfected tumour cells in patients with glioblastoma multiforme. Autologous tumour cells harvested during surgery were cultured and transduced with the human IFN-γ gene. Irradiated cells were administered as intradermal immunizations ev
Our societies are ageing, and an urban-regional perspective on these developments is urgently needed. This figure shows an uneven geography of population ageing in Sweden—in the level and pace of ageing—and calls for variegated societal adaptations across municipalities.
In this thesis, a high-repetition-rate attosecond light source based on high-order harmonic generation in gases was used to perform time-resolved electron spectroscopy in atoms and solids. The source was driven by few-cycle near-infrared laser pulses with a controllable carrier-to-envelope phase, enabling the generation of sequences of two to four attosecond pulses in the extreme ultraviolet range
Carbon moves through the atmosphere, through the oceans, onto land, and into ecosystems. This cycling has a large effect on climate – changing geographic patterns of rainfall and the frequency of extreme weather – and is altered as the use of fossil fuels adds carbon to the cycle. The dynamics of this global carbon cycling are largely predicted over broad spatial scales and long periods of time by
This open access book examines the formation and sustainability of private credit networks in past societies, gathering a global range of case studies from Europe and the Americas. The book represents a fi rst attempt to coordinate the work of different scholars working on credit networks and aims to explore the possibilities offered by social network analysis for the study of past fi nancial mark
Natural products are emerging as valuable tools in insect pest management, particularly as synergists that enhance insecticidal activity while potentially reducing chemical usage and mitigating resistance. This chapter explores the role of natural products in boosting the efficacy of both synthetic and botanical insecticides. First, the chapter focuses on the current regulatory status of synergist
Attosecond pulses produced by high-order harmonic generation in gases driven by intense laser fields have become a cornerstone technique for probing ultrafast electronic motion in matter. These applications require a good knowledge of the temporal and spectral properties of the emitted radiation. In this work, we generate a train of two to three attosecond pulses that we characterize using two-col
