Repeatability Assessment in Tunnel Fire Experiments

A medium-scale experimental setup located in Revinge, Sweden, is used to generate new repeated experimental datasets focussed on measuring a set of key variables, including time-temperature curves and temperature profiles. A total of 6 repeated fire tests were conducted and are here used to exemplify typical issues associated with repeatability, uncertainty and variability in tunnel fire experimen

Rotational Locomotion in Large-Scale Environments: A Survey and Implications for Evidence-Based Design Practice

Navigation performance in urban and large-scale built-up spaces (e.g. airports, train-stations, hospitals) depends on gradual environmental perception during locomotion, and spatial knowledge acquisition, update/integration at different times along a path. Rotational locomotion is regularly involved in everyday navigation; this, combined with the fact that people cannot perceive the whole of a lar

Pastureland restoration is urgent for Sámi reindeer pastoralism to coexist with the forest industry and adapt to climate change in Northern Sweden

Key recommendationsPastureland restoration must be implemented to reduce dependency oncoping mechanisms such as emergency feeding, mechanized transport andintense workloads. These coping mechanisms are increasingly used to dealwith the cumulative effects of encroachments from competing land uses,predator pressure, and the impacts of climate change on snow conditions.Vigorous thinning of dense, man

Balance and gait disorders in de novo Parkinson’s disease : support for early rehabilitation

BACKGROUND: Postural instability is considered a late complication of Parkinson’sdisease (PD). However, growing evidence shows that balance and gait problems mayoccur early in the disease.OBJECTIVE: To describe balance, gait, and falls/near falls in persons with newlydiagnosed, untreated PD (“de novo”), and to compare this with persons with mildmoderatePD (Later PD). In addition, we evaluated diffBackgroundPostural instability is considered a late complication of Parkinson’s disease (PD).

Local genetic correlation via knockoffs reduces confounding due to cross-trait assortative mating

Local genetic correlation analysis is an important tool for identifying genetic loci with shared biology across traits. Recently, Border et al. have shown that the results of these analyses are confounded by cross-trait assortative mating (xAM), leading to many false-positive findings. Here, we describe LAVA-Knock, a local genetic correlation method that builds off an existing genetic correlation

Art, aging, and artificial intelligence: Exploring age scripts in the universe of ai-generated art

This study investigates age-related biases in AI-generated art through a mixed method investigation of images of older and younger individuals. Employing 19 text prompts associated with social exclusion for older adults, we collected 465 images from an AI-art generator, MidJourney, and conducted quantitative and qualitative analyses to understand differences between age group depictions. We used A

Hawaiiskjortans estetik

En kulturhistorisk perspketivering med plagget Hawaiiskjortan i fokus. Dels beskrivs Hawaiiskjortan som sådan, historisk etablering, i ett internetaionellt såväl som inrikes svenskt läge; dels förs resonemang om Hawaiiskjortans symboliska och betydelseproducerande roll i populärkulturen (TV-serier, filmer, musik av olika slag).

SMS121, a new inhibitor of CD36, impairs fatty acid uptake and viability of acute myeloid leukemia

Acute myeloid leukemia (AML) is the most common form of acute leukemia in adults and the second most common among children. AML is characterized by aberrant proliferation of myeloid blasts in the bone marrow and impaired normal hematopoiesis. Despite the introduction of new drugs and allogeneic bone marrow transplantation, patients have poor overall survival rate with relapse as the major challeng

Plant diversity enhances ecosystem multifunctionality via multitrophic diversity

Ecosystem functioning depends on biodiversity at multiple trophic levels, yet relationships between multitrophic diversity and ecosystem multifunctionality have been poorly explored, with studies often focusing on individual trophic levels and functions and on specific ecosystem types. Here, we show that plant diversity can affect ecosystem functioning both directly and by affecting other trophic

Natural Concepts and the Economics of Cognition and Communication

This article takes a cognitive approach to natural concepts. The aim is to introduce criteria that are evaluated with respect to how they support the cognitive economy of humans when using concepts in reasoning and communicating with them. I first present the theory of conceptual spaces as a tool for expressing the criteria. Then I introduce the central idea that natural concepts correspond to con

RealTimeTransport: An open-source C++ library for quantum transport simulations in the strong coupling regime

The description of quantum transport in the strong system-reservoir coupling regime poses a significant theoretical and computational challenge that demands specialized tools for accurate analysis. RealTimeTransport is a new open-source C++ library that enables the computation of both stationary and transient transport observables for generic quantum systems connected to metallic reservoirs. It co

A Call to Holiness : Baptism, the Church, and Asceticism in Jerome's Adversus Jovinianum

Scholarship on the Jovinianist controversy has shown that the idea of baptism as deeply transformative lay at the heart of Jovinian's thinking. Scholars have likewise held that Jerome, who through his Adversus Jovinianum is our main source to the ideas of Jovinian, did not acknowledge the ecclesiological concerns on which his opponent's argument was based. This article argues, to the contrary, tha

Multi-hazard life-cycle consequence analysis of deteriorating engineering systems

Probabilistic life-cycle consequence (LCCon) analysis (e.g., assessment of repair costs, downtime, or casualties over an asset's service life) can enable optimal life-cycle management of critical assets under uncertainties. This can lead to effective risk-informed decision-making for future disaster management (i.e., risk mitigation and/or resilience-enhancing strategies/policies) implementation.

Visualization of soil aggregate structures provides insights into their formation mechanisms induced by litter inputs

Soil aggregation is a dynamic process influenced by physical, chemical and biological factors; however, their individual and combined effect on the formation and turnover of aggregates is not well understood. The aim of this study was to examine incorporation of fresh litter inputs of different physicochemical properties including their carbon-to-nitrogen (C/N) ratio – maize (C/N = 12) and straw (

Distribution of infectious and parasitic agents among three sentinel bee species across European agricultural landscapes

Infectious and parasitic agents (IPAs) and their associated diseases are major environmental stressors that jeopardize bee health, both alone and in interaction with other stressors. Their impact on pollinator communities can be assessed by studying multiple sentinel bee species. Here, we analysed the field exposure of three sentinel managed bee species (Apis mellifera, Bombus terrestris and Osmia

Proposal for revised criteria for daylight provision in the European daylight standard based on calculations for Swedish multifamily residential buildings

The European standard EN 17037 was first introduced in 2018 with the aim of encouraging building designers to ensure adequate daylight in buildings. Experience has shown that the standard’s criteria for daylight provision are generally perceived to be too challenging, and this in turn has hindered its implementation in national legislations. This article proposes a revised illuminance-based criter

CDK4 is co-amplified with either TP53 promoter gene fusions or MDM2 through distinct mechanisms in osteosarcoma

Amplification of the MDM2 and CDK4 genes on chromosome 12 is commonly associated with low-grade osteosarcomas. In this study, we conducted high-resolution genomic and transcriptomic analyses on 33 samples from 25 osteosarcomas, encompassing both high- and low-grade cases with MDM2 and/or CDK4 amplification. We discerned four major subgroups, ranging from nearly intact genomes to heavily rearranged

Impact of Al profile in high-Al content AlGaN/GaN HEMTs on the 2DEG properties

Ultra-thin high-Al content barrier layers can enable improved gate control and high-frequency operation of AlGaN/GaN high electron mobility transistors (HEMTs) but the precise composition control is very challenging. In this work, we investigate the compositional profiles of AlxGa1−xN/GaN HEMT structures with targeted Al content in the barrier layer, x = 0.50, 0.70, and 1, and thickness in the sub
