An optimal control problem on finite-dimensional positive cones is stated. Under a critical assumption on the cone, the corresponding Bellman equation is satisfied by a linear function, which can be computed by convex optimization. A separate theorem relates the assumption on the cone to the existence of minimal elements in certain subsets of the dual cone. Three special cases are derived as examp
Cybersecurity has in recent years emerged as a paramount concern in the design and operation of industrial systems and civil infrastructures, due mainly to their susceptibility to malicious cyber attacks which take advantage of the vulnerability of communication networks and IT devices. In this paper, we investigate such an attack and counter attack scenario by considering multiagent systems, a so
Integration of high-quality oxides on III-V materials allows for versatile design of electronic devices, suitable for RF and power applications. We here present an overview of our results of planar and non-planar III-V MOSFETs for RF electronics, highlighting possibilities and challenges.
A group of young scholars revisit the aims, nature, and purpose of New DiplomaticHistory.
On-chip light broadcasting can reduce spatial footprint and enhance energy efficiency in photonic neuromorphic systems. We demonstrate on-chip light transmission between InP nanowire photodiodes on silicon, addressing the gap towards complete nanoscale photonic integrated circuits.
Maladaptive daydreaming is a distinct syndrome in which themain symptom is excessive vivid fantasising that causesclinically significant distress and functional impairment inacademic, vocational and social domains. Unlike normaldaydreaming, maladaptive daydreaming is persistent, compulsiveand detrimental to one’s life. It involves detachmentfrom reality in favour of intense emotional engagement wi
Background: In the Malmö Breast Tomosynthesis Screening Trial (MBTST), digital breast tomosynthesis (DBT) increased the detection rate of breast cancer compared to currently used digital mammography (DM). This study evaluated the cost effectiveness of DBT versus DM in Sweden using data from MBTST. Materials and method: A health economic model was used to compare a breast cancer screening programme
Despite a growing body of research on the role of the Sustainable Development Goals (SDGs) at the local level, knowledge on how they are taken up in local governance processes remains limited. This article contributes to knowledge on SDG implementation by examining how the SDGs can contribute to governance change at the local level. We develop a process-oriented analytical framework that examines
The United Nations (UN) put out a questionnaire and request for public comment on a proposal to form an Independent International Scientific Panel on ArtificialIntelligence (AI), as well as a Global Dialogue on AI in the context of the Global Digital Compact. The questionnaire was sent out in late 2024, and the following brief report forms the response submitted by the AI Policy Lab at Umeå Univer
This article examines the expanding role of Artificial Intelligence (AI) in healthcare and associated human rights concerns, including whether new EU legislation takes all relevant human rights concerns into account. AI presents promising ways to fulfil the right to health through improving diagnostics, treatments, and resource allocation, but its use also comes with risks concerning privacy, bias
Based on the perspective of frontline staff who work closely with adults with intellectual disabilities (ID) in group homes in Sweden, this article explores ethical dilemmas that arise when daily tasks intersect with efforts to achieve the disability policy goal of self-determination and the nature of close work relationships. Using the successive focus group interview method, the study highlights
Industry body’s decision to accept Novo Nordisk back reflects systemic failures
Under Covid-19-pandemin anpassade Svenska kyrkan sina nattvardspraktiker på ett flertal olika sätt. Anpassningarna motiverades och problematiserades i relation till gemenskap, ofta med hänvisning till en metafor som varit avgörande i utvecklingen av Svenska kyrkans teologi under 1900-talet: "Kristi kropp". Det spekulerades också både inom forskningen och i den allmänna debatten, för huruvida dessaDuring the Covid-19-pandemic, the Church of Sweden (CofS) adjusted its eucharis-tic practices, and congregations practiced a variety of adjustments. These adjust-ments were motivated and problematized in relation to community, often refer-encing a metaphor crucial in the development of CofS theology during the 20th Century: “the body of Christ.” Scholars also speculated on how these adjustments co
Extracellular contractile injection systems (eCISs) are phage-derived nanomachines used by bacteria to deliver effectors into target cells. Well-studied examples include the Photorhabdus asymbiotica virulence cassettes and the antifeeding prophage from Serratia entomophila, which have been engineered for heterologous cargo delivery. Recent genomic analyses identified previously uncharacterized eCI
