In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on energy efficiency. We develop a long-run, worldwide societal exergy analysis focused on electricity. Our 1900–2017 electricity world database contains the energy carriers used in electricity production, final end-u

Comparing 3D neutron and X-ray microtomography (NCT and XCT) results of fully pyrolyzed and pristine samples, we observed that the contrast in the neutron images increased for the carbonized samples, suggesting that H would be concentrated at the surface of the carbonized material structure.

OBJECTIVE: Previous studies have suggested that transportation noise may increase risk for breast cancer, but existing literature is scarce and inconclusive. We aimed to investigate associations between road traffic and railway noise and risk for breast cancer across the entire Danish female population.METHODS: For all 2.8 million residential addresses across Denmark, we modelled road and railway

In this paper, we discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g. voice and video) over best effort networks with sufficient quality. We take a practical view of content distribution and quality, and this is the reason for the term “sufficient”. We argue that the understanding of quality as perceived by the user is a k

Abstract in UndeterminedA more or less continuous process of structural change, not least due to a globalizing economy, poses a number of challenges to regions and local communities. However, when firms or whole industries are phasing out, windows of opportunity open up. Empirical analyses of two recent plant closures in Skane point at the importance of retaining existing knowledge bases, and at t

Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential. However, clonal plants have revealed similar levels of gene

The optical spectra of a quantum cascade laser structure under nonequilibrium conditions is studied using the technique of nonequilibrium Green functions. We focus on the impact of Coulomb corrections and their dependence on the operating conditions. The role of the static mean field due to the charge distribution by electrons and ioninzed donors is investigated.

Introduction: Implementing new treatment regimens entails a learning phase with a concomitant risk of suboptimal results. High caseload has generally been shown to improve results in complex surgical procedures. This study aimed to evaluate results of Cytoreductive Surgery (CRS) and Intraperitoneal Chemotherapy (IP), given as Early Postoperative Intraperitoneal Chemotherapy (EPIC) or Hyperthermic

Understanding regional variation in public transport preferences is essential for designing efficient mobility systems. This study examines the stability of preferences for both traditional public transport and demand-responsive transport across three Swedish regions–Stockholm (urban), Skåne (intermediate), and Värmland (rural)–using discrete choice experiments. The analysis focuses on key service

The rise of solo living presents significant social and environmental challenges, particularly in high-income countries like Denmark where nearly half of households are single occupancy. This study explores the social dynamics driving the trend towards living alone through in-depth interviews with 23 individuals living alone in Denmark. Pathways to solo living include urban relocation, aging out o

How environmental and climate challenges that often evoke strong negative emotions are communicated and responded to is of great importance. These include forest fires, plastic pollution and flooding that can produce fear, sadness and powerlessness. Images are important to this communication, yet how these challenges are captured through visual communication tools and to what outcomes requires fur

We present PyeLink and SyeLink, two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink eye tracking hardware. PyeLink simplifies experiment creation through plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) while enabling two features not available in existing tools: recording data during calibrati
