COVID-19 and airborne transmission : science rejected, lives lost : can society do better?

This is an account that should be heard of an important struggle: the struggle of a large group of experts who came together at the beginning of the Covid-19 pandemic to warn the world about the risk of airborne transmission and the consequences of ignoring it. We alerted the World Health Organization (WHO) about the potential significance of the airborne transmission of SARS-CoV-2 and the urgent

Observing the Sunni-Shiʿa Divide in Fieldwork : The When and Where of Muslim Identities

Based on an ethnographic study of non-conformist mosques, this article demonstrates how Muslims may adopt a Sunni or Shiʿa identity while navigating spaces that are institutionalised as such but give much less importance to this identity – if any – when occupying less structured spaces. It may, for example, have little influence on what religious literature they read, which preachers they follow o

Seasonal changes in plumage density, plumage mass, and feather morphology in the world’s northernmost land bird, the Svalbard Rock Ptarmigan (Lagopus muta hyperborea)

The Svalbard Rock Ptarmigan, Lagopus muta hyperborea, is the only year-round resident terrestrial bird in the high Arctic. Many of the physiological and morphological adaptations permitting its winter endurance in this harsh environment are well understood. However, it remains unknown how the conspicuous moult from a greyish brown summer to a white winter plumage, and any underlying changes in pluThe Svalbard Rock Ptarmigan, Lagopus muta hyperborea, is the only year-round resident terrestrial bird in the high Arctic.

Workload Characterization and Traffic Analysis for Reconfigurable Intelligent Surfaces within 6G Wireless Systems

Programmable metasurfaces constitute an emerging paradigm, envisaged to become a key enabling technology for Reconfigurable Intelligent Surfaces (RIS) due to their powerful control over electromagnetic waves. The HyperSurface (HSF) paradigm takes one step further by embedding a network of customized integrated circuit (IC) controllers within the device with the aim of adding intelligence, connecti

The Missing Link : The implementation of priorities for research, development, and innovation

The thesis explores the ‘missing link’ in the study of priority-setting for research, development, and innovation (RDI), namely the processes of implementing RDI priorities, and the consequences of these processes. It does so by focusing on how choices, actions, and motivations of implementers of RDI priorities established elsewhere in the policy system enact, or carry out, the priorities, resulti

Linearization techniques for band structure calculations in absorbing photonic crystals

Band structure calculations for photonic crystals require the numerical solution of eigenvalue problems. In this paper, we consider crystals composed of lossy materials with frequency-dependent permittivities. Often, these frequency dependencies are modeled by rational functions, such as the Lorentz model, in which case the eigenvalue problems are rational in the eigenvalue parameter. After spatia

Ukrainians

In 1921, disgruntled and radicalised veterans of the First World War organised the Ukrainian Military Organisation (UVO) after unsuccessfully taking up arms for Ukrainian independence. In 1929 the UVO merged with a number of other far-right groups and student fraternities into the Organisation of Ukrainian Nationalists. The leading figure in the 1920s and 1930s was Evhen’ Konovalets’, a former col

The dynamic and iterative pre-dispute phases: the transformation from a justiciable problem into a legal dispute

The pre-dispute phase, during which justiciable problems may or may not emerge and transform into legal cases, is complex. Based on a meta-ethnography of 572 articles, all of which apply or refer to Felstiner et al.’s pioneering linear framework of naming, blaming, and claiming, we analysed the many sorting mechanisms that are at play in the pre-dispute phase. We identified the institutional, poli

Future of digital work : challenges for sustainable human resources management

This research aims to present a synopsis of four eminent theoretical concepts that scholars have expended to help understand how digitalisation has changed the workplace as we used to know it. The research is based on a conceptual approach. It aims to critically synthesise the relevant literature as the principal methodology for analysing work in the selected four research domains where the perspe

Lightweight Machine Learning for Seizure Detection on Wearable Devices

For patients with epilepsy, automatic epilepsy monitoring, i.e., the process of direct observation of the patient’s health status in real time, is crucial. Wearable systems provide the possibility of real-time epilepsy monitoring and alerting caregivers upon the occurrence of a seizure. In the context of the ICASSP 2023 Seizure Detection Challenge, we pro- pose a lightweight machine-learning frame

Två för Skandinavien nya tripsarter (Thysanoptera): Hoplothrips caespitis (Uzel, 1895) och Megalothrips bonannii Uzel, 1895 samt nya provinsfynd

Hoplothrips caespitis (Uzel, 1895) and Megalothrips bonannii Uzel, 1895 were recorded for the first time in Sweden, and the species are also new to Scandinavia. The species were found in Scania (Skåne) in the southernmost part of Sweden in dry grassland habitat and close to a small river. Two additional species Aeolothrips astutus Priesner, 1926 and Odontothrips biuncus John, 1921 are new to the p

Polyhydroxyalkylations for alkali-stable cationic polymers as hydroxide exchange membranes

To alleviate worldwide dependence on fossil fuels for energy production and considerably reduce CO2 emissions, green energy sources and sustainable energy solutions are in high demand. Fuel cells are environmental-friendly electrochemical devices which may use clean fuels, e.g., green hydrogen gas, to generate electricity. Meanwhile, water electrolyzers provide an efficient strategy to produce gre

Association Between Hip Muscle Function And Hip-Specific Patient-Reported Outcomes In Patients With Longstanding Pre-Arthritic Hip And Groin Pain

Patients referred to orthopeadic care due to longstanding hip and groin pain often suffers from hip-related pain. Hip-related pain such as femoroacetabular impingement syndrome may lead to early onset of hip osteoarthritis. Previous research has shown that patients with longstanding hip and groin pain have poor patient-reported outcomes compared to healthy controls. Also, decreased hip muscle stre

Genetic Susceptibility to Mood Disorders and Risk of Stroke : A Polygenic Risk Score and Mendelian Randomization Study

BACKGROUND: Mood disorders and strokes are often comorbid, and their health toll worldwide is huge. This study characterizes prognostic and causal roles of mood disorders in stroke.METHODS: We tested if genetic susceptibilities for mood disorders were associated with all strokes, ischemic strokes in the Malmö Diet and Cancer cohort (24 631 individuals with a median follow-up of 21.3 (interquartile
