Cryptology in the Crowd
(Doctoral thesis, 2023-12-08)Uhell skjer: Kanskje mistet du nøkkelen til huset, eller hadde PIN-koden til innbruddsalarmen skrevet på en dårlig plassert post-it lapp. Og kanskje endte de slik opp i hendene på feil person, som nå kan påføre livet ditt ... -
Scalable Learning of Bayesian Networks Using Feedback Arc Set-Based Heuristics
(Doctoral thesis, 2023-11-10)Bayesianske nettverk er en viktig klasse av probabilistiske grafiske modeller. De består av en struktur (en rettet asyklisk graf) som beskriver betingede uavhengighet mellom stokastiske variabler og deres parametere (lokale ... -
On the Significance of Distance in Machine Learning
(Doctoral thesis, 2023-10-23)Avstandsbegrepet er grunnleggende i maskinlæring. Hvordan vi velger å måle avstand har betydning, men det er ofte utfordrende å finne et passende avstandsmål. Metrisk læring kan brukes til å lære funksjoner som implementerer ... -
Det regionale i det internasjonale - en internasjonaliseringsstrategi for høyskolene på Vestlandet
(Chapter, 2018)Fra å starte som rene undervisningsinstitusjoner har høyskolene nå fått krav om å være relevante i en forskningssammenheng. Spørsmålet er da – hvordan kan små institusjoner i utkanten av verden operere internasjonalt? Mitt ... -
Facilitating Extended Reality in Museums through a Web-Based Application
(Master thesis, 2023-06-01) -
Cystatin C is glucocorticoid responsive, directs recruitment of Trem2+ macrophages, and predicts failure of cancer immunotherapy
(Journal article; Peer reviewed, 2023)Cystatin C (CyC), a secreted cysteine protease inhibitor, has unclear biological functions. Many patients exhibit elevated plasma CyC levels, particularly during glucocorticoid (GC) treatment. This study links GCs with ... -
Convexity, convolution and competitive equilibrium
(Journal article; Peer reviewed, 2023)This paper considers a chief interface between mathematical programming and economics, namely: money-based trade of perfectly divisible and transferable goods. Three important and related features are singled out here: ... -
Designing a Simulation showcasing the Pharmacological Effects of Beta-2-Agonists in Asthma Treatment; Virtual Reality as a supplement to traditional teaching methods
(Master thesis, 2023-06-01)As educational technology evolves, there is a growing interest in applying VR in teaching complex scientific concepts that benefit from a visual and immersive learning environment. Motivated by the promising results of VR ... -
Lossy Kernelization of Same-Size Clustering
(Journal article; Peer reviewed, 2023)In this work, we study the k-median clustering problem with an additional equal-size constraint on the clusters from the perspective of parameterized preprocessing. Our main result is the first lossy (2-approximate) ... -
Plasma cortisol linked gene networks in hepatic and adipose tissues implicate corticosteroid binding globulin in modulating tissue glucocorticoid action and cardiovascular risk
(Journal article; Peer reviewed, 2023)Genome-wide association meta-analysis (GWAMA) by the Cortisol Network (CORNET) consortium identified genetic variants spanning the SERPINA6/SERPINA1 locus on chromosome 14 associated with morning plasma cortisol, cardiovascular ... -
An infinite family of 0-APN monomials with two parameters
(Journal article; Peer reviewed, 2023)We consider an infinite family of exponents e(l, k) with two parameters, l and k, and derive sufficient conditions for e(l, k) to be 0-APN over F2n . These conditions allow us to generate, for each choice of l and k, an ... -
Structural Operational Semantics for Heterogeneously Typed Coalgebras
(Journal article; Peer reviewed, 2023)Concurrently interacting components of a modular software architecture are heterogeneously structured behavioural models. We consider them as coalgebras based on different endofunctors. We formalize the composition of these ... -
Computational complexity aspects of super domination
(Journal article; Peer reviewed, 2023)Let G be a graph. A dominating set D ⊆ V (G) is a super dominating set if for every vertex x ∈ V (G) \ D there exists y ∈ D such that NG (y) ∩ (V (G) \ D)) = {x}. The cardinality of a smallest super dominating set of G is ... -
Do Disease Stories Need a Hero? Effects of Human Protagonists on a Narrative Visualization about Cerebral Small Vessel Disease
(Journal article; Peer reviewed, 2023)Authors use various media formats to convey disease information to a broad audience, from articles and videos to interviews or documentaries. These media often include human characters, such as patients or treating physicians, ... -
Algebraic Reasoning About Timeliness
(Journal article; Peer reviewed, 2023)Designing distributed systems to have predictable performance under high load is difficult because of resource exhaustion, non-linearity, and stochastic behaviour. Timeliness, i.e., delivering results within defined time ... -
Modelling overfow using mixed integer programming in short‑term hydropower scheduling
(Journal article; Peer reviewed, 2023)Short-term hydropower scheduling seeks to find a production schedule that maximizes profit, but must also consider the hydrological balance and risk of overflow. Overflow is by nature a non-linear and non-convex phenomenon. ... -
Mining EL⊥ Bases with Adaptable Role Depth
(Journal article; Peer reviewed, 2023)In Formal Concept Analysis, a base for a finite structure is a set of implications that characterizes all valid implications of the structure. This notion can be adapted to the context of Description Logic, where the base ... -
On the maximum number of edges in planar graphs of bounded degree and matching number
(Journal article; Peer reviewed, 2023)We determine the maximum number of edges that a planar graph can have as a function of its maximum degree and matching number. -
Strongly Stable Stationary Points for a Class of Generalized Equations
(Journal article; Peer reviewed, 2023)In this paper we consider a generalized equation that is mainly characterized by a cone-valued mapping. It is well known that optimality conditions for different classes of optimization problems can be formulated as such ...
