Lifestyle factors as mediators of area-level socioeconomic differentials in mental health and cognitive function: the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-22)Introduction - Low socioeconomic status (SES) is associated with poor mental health and cognitive function. Individual-level SES and area-level SES (ASES) may affect mental health and cognitive function through lifestyle. We aimed to quantify the associations of ASES with mental health and cognitive function and examine the mediating role of lifestyle behaviours independent of individual-level SES ... -
Analysis of Deep Convolutional Neural Networks Using Tensor Kernels and Matrix-Based Entropy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-03)Analyzing deep neural networks (DNNs) via information plane (IP) theory has gained tremendous attention recently to gain insight into, among others, DNNs’ generalization ability. However, it is by no means obvious how to estimate the mutual information (MI) between each hidden layer and the input/desired output to construct the IP. For instance, hidden layers with many neurons require MI estimators ... -
Introducing extended consultations for patients with severe mental illness in general practice: Results from the SOFIA feasibility study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-05)Background - People with a severe mental illness (SMI) have shorter life expectancy and poorer quality of life compared to the general population. Most years lost are due to cardiovascular disease, respiratory disease, and various types of cancer. We co-designed an intervention to mitigate this health problem with key stakeholders in the area, which centred on an extended consultations for people ... -

From Winter to Late Summer in the Northwestern Barents Sea Shelf: Impacts of Seasonal Progression of Sea Ice and Upper Ocean on Nutrient and Phytoplankton Dynamics
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-11)Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the interannual variability and long-term changes of the Barents Sea are well-documented, the seasonal progression of the physical and biological systems is less known, mainly due to poor accessibility of the seasonally ice-covered area in winter and spring. Here, we use an extensive set of physical and biological ... -

Påvirker perturbasjonsbasert balansetrening balanse og gange hos personer med Parkinson sykdom?
(Master thesis; Mastergradsoppgave, 2022-05-03)<p><i>Hensikt:</i> Parkinson sykdom (PS) er en begrensende nevrologisk sykdom på kroppsfunksjoner og livskvalitet. Personer med Parkinson sykdom (PmP) kan i flere tilfeller oppleve nedsatt balanse og gangfunksjon, og redusert tro på egne ferdigheter. Nedsatt gangfunksjon, balanse og tro på egen balanse kan føre til fall eller økt inaktivitet. Og dette kan føre til mer inaktivitet hos PmP enn hos ... -
