Intelligent digital tools for screening of brain connectivity and dementia risk estimation in people affected by mild cognitive impairment: the AI-Mind clinical study protocol
(Peer reviewed; Journal article, 2023)More than 10 million Europeans show signs of mild cognitive impairment (MCI), a transitional stage between normal brain aging and dementia stage memory disorder. The path MCI takes can be divergent; while some maintain ... -
Estimating volcanic ash emissions using retrieved satellite ash columns and inverse ash transport modelling using VolcanicAshInversion v1.2.1, within the operational eEMEP volcanic plume forecasting system (version rv4_17)
(Peer reviewed; Journal article, 2024)Accurate modeling of ash clouds from volcanic eruptions requires knowledge about the eruption source parameters including eruption onset, duration, mass eruption rates, particle size distribution, and vertical-emission ... -
Random sparse generators of Markovian evolution and their spectral properties
(Peer reviewed; Journal article, 2023)The evolution of a complex multi-state system is often interpreted as a continuous-time Markovian process. To model the relaxation dynamics of such systems, we introduce an ensemble of random sparse matrices which can be ... -
Technological Utilization in Remote Healthcare: Factors Influencing Healthcare Professionals' Adoption and Use

Efficient Estimation of Generative Models Using Tukey Depth
(Peer reviewed; Journal article, 2024)Generative models have recently received a lot of attention. However, a challenge with such models is that it is usually not possible to compute the likelihood function, which makes parameter estimation or training of ... -
A dataset for predicting cloud cover over Europe
(Peer reviewed; Journal article, 2024)Clouds are important factors when projecting future climate. Unfortunately, future cloud fractional cover (the portion of the sky covered by clouds) is associated with significant uncertainty, making climate projections ... -
Peer-Mentoring for Students with Disabilities – A Preliminary Study in Norwegian Higher Education
(Lecture Notes in Computer Science;, Chapter; Peer reviewed; Conference object; Journal article, 2023)The number of students with disabilities in higher education is increasing.
