Closed-form conditions for bound states in the continuum are derived for planar, cylindrical, and spherical cavities enclosed by metasurfaces with electric and magnetic response. While the combined response in lossless systems enables field confinement in arbitrarily small cavities, the gain-enabled bound states in the continuum are found to coalesce with a laser mode, leading to intriguing single
Given the increasing number of heterogeneous data stored in relational databases, file systems or cloud environment, it needs to be easily accessed and semantically connected for further data analytic. The potential of data federation is largely untapped, this paper presents an interactive data federation system (https://vimeo.com/319473546) by applying large-scale techniques including heterogeneo
The paper explores what the methodological considerations are for a study of educational practice and networked learning in technologically dense classrooms. The approach of the discussed study is informed by Actor-Network Theory (ANT) (Latour, 2005) and the paper outlines the methodological consequences for adopting principles associated with ANT and post-humanist critiques of representational ep
For many years, questions about the future have been marginalised within the social sciences: asking how we might live in a post-fossil society, or what are the key decisions and events that could take us there, has been seen as outside of the disciplinary scope. In this chapter – which takes as its point of departure the ‘speculative turn’ that is increasingly inspiring a range of works, from for
Inferring the cell-type composition of bulk samples can provide biological insight. While bulk transcriptomics data has been extensively used for this purpose, the use of proteomics data has remained unexplored until recently. This study evaluates computational approaches for estimating immune cell composition using bulk sample proteomics data. Leveraging defined immune cell populations and simula
A radiation detection system combining a single-sided silicon strip detector (SSSD) and a high-purity germanium (HPGe) COMPEX detector module together with its anti-Compton shield (ACS) was set up at Lund University for environmental sample measurements. This system enables high sensitivity ––-coincidence analysis, enhancing the identification level of radionuclides in environmental samples. A com
Photonics technologies play a crucial role in driving technological advancements within the agrifood industry, aiming to deliver a sustainable food and agriculture, and offering healthy, nutritious and safe food for all of us. Particularly, optical sensors and imaging systems, together with machine-learning processing and advanced lighting, play a pivotal role in monitoring crop and soil health wi
This study presents a modular approach for the synthesis of multifunctional affinity sorbents, facilitating molecular separation via magnetic molecularly imprinted polymers. A magnetic propranolol-imprinted polymer (MIP) nanocomposite with superparamagnetic characteristics was synthesized through precipitation polymerization process coupled with coprecipitation methods. Initially, the propranolol-
OBJECTIVES: Implementation of the Stroke Action Plan for Europe (2018-2030) (SAP-E) was initiated in 2019. It is now updated at mid-term to reflect and respond to challenges for stroke care in Europe in 2025. METHODS: The SAP-E covers the entire chain of stroke care. The sections (state of the art, current status and targets) were developed by working groups and finalised based on inputs from the
BACKGROUND: Despite decades of initiatives promoting individual behavior change, obesity rates remain high and continue to rise globally, indicating that what is commonly labelled as “obesity prevention” is not, in practice, preventing obesity. While health promotion strategies and policy interventions have demonstrated improvements in environments, health behaviors, and industry practices, their
Wildfires, insect outbreaks, and storms cause large pulses of tree mortality. Climate change amplifies these forest disturbances, yet their future magnitude and extent remain uncertain. Here, we simulated future forest disturbance regimes at 100-meter resolution across Europe using a deep learning–based simulation framework. Our results show that forest disturbances will continue to increase throu
Hadfield steel is widely used in heavy-duty applications involving high impact loads and abrasive wear, such as mining and stone crushing equipment, due to its high toughness, ductility, and work-hardening ability. However, the as-cast microstructure contains carbide precipitation and chemical segregation, particularly along grain boundaries, which causes embrittlement and reduce service performan
Early Warning Systems (EWS) are crucial for safeguarding communities, but are vulnerable to failure due to a technocratic focus that excludes local communities. This thesis closes the gap between normative participatory principles and practical implementation by exploring the entry points or challenges that affect community participation. Adopting a complexity theory lens, the study conducts a qua
Komplex mjukvara kräver testning på flera nivåer. Detta examensarbete undersöker automatiserad testning av Radio Block Centre (RBC). En RBC bestämmer hur långt ett tåg får köra och i vilken hastighet. Examensarbetet har tre fokusområden. Det första området undersöker hur nuvarande testscript kan göras mer dynamiska genom att införa slumpmässighet. Slumpmässighet införs genom att variera tåglängd. Complex software must be tested carefully. This thesis looks at how automated testing can be improved for Alstom’s Radio Block Centre, a system that supervises trains and sends movement authorities. The work focuses on three practical ways to improve an existing automated test setup. First, it studies how the test suite can be made more dynamic by introducing randomness into current test scripts.
Drylands are water-limited systems that collectively sustain hundreds of millions of people, yet land–atmosphere feedbacks such as terrestrial moisture recycling remain poorly quantified. In particular, the origins of precipitation in China's drylands and their atmospheric water vapor budgets remain unclear. Here we use a Lagrangian moisture-tracking model to quantify atmospheric moisture sources
