CSF circulation and dispersion yield rapid clearance from intracranial compartments
(Journal article; Peer reviewed, 2022-09-12)In this paper, we used a computational model to estimate the clearance of a tracer driven by the circulation of cerebrospinal fluid (CSF) produced in the choroid plexus (CP) located within the lateral ventricles. CSF was ... -
Cubical and cosimplicial descent
(Peer reviewed; Journal article, 2018)We prove that algebraic K ‐theory, topological Hochschild homology and topological cyclic homology satisfy cubical and cosimplicial descent at connective structured ring spectra along 1‐connected maps of such ring spectra. -
Curvature and Harmonic Forms on Complete Manifolds

Cyclic homology in a special world
(Chapter, 2020)In work of Connes and Consani, Γ-spaces have taken a new importance. Segal introduced Γ-spaces in order to study stable homotopy theory, but the new perspective makes it apparent that also information about the unstable ... -
Daily Contributors of Tinnitus Loudness and Distress: An Ecological Momentary Assessment Study
(Journal article; Peer reviewed, 2022)Background: Tinnitus is a heterogeneous condition which may be associated with moderate to severe disability, but the reasons why only a subset of individuals is burdened by the condition are not fully clear. Ecological ... -

DarSIA: An Open-Source Python Toolbox for Two-Scale Image Processing of Dynamics in Porous Media
(Journal article; Peer reviewed, 2023)Understanding porous media flow is inherently a multi-scale challenge, where at the core lies the aggregation of pore-level processes to a continuum, or Darcy-scale, description. This challenge is directly mirrored in image ... -
Data on gender contrasts in the risk of incident myocardial infarction by age. The Tromsø Study 1979-2012
(Peer reviewed; Journal article, 2017-08)The data presented in this article relate to the research article entitled “Risk of incident myocardial infarction by gender: Interactions with serum lipids, blood pressure and smoking. The Tromsø Study 1979–2012” (Albrektsen ... -
Data science approaches provide a roadmap to understanding the role of abscisic acid in defence
(Journal article; Peer reviewed, 2023)Abscisic acid (ABA) is a plant hormone well known to regulate abiotic stress responses. ABA is also recognised for its role in biotic defence, but there is currently a lack of consensus on whether it plays a positive or ... -
Data-based methods for analysing single-point ocean wave measurements
(Master thesis, 2024-11-18)This master’s thesis aims to enhance techniques for understanding, modelling, and predicting ocean surface processes using undersampled data and incomplete information about the system’s state and physical principles. Using ... -
Data-Driven Inference Reveals Distinct and Conserved Dynamic Pathways of Tool Use Emergence across Animal Taxa
(Journal article; Peer reviewed, 2020)Tool use is a striking aspect of animal behavior, but it is hard to infer how the capacity for different types of tool use emerged across animal taxa. Here we address this question with HyperTraPS, a statistical approach ... -
DCC-GARCH modeller med ulike avhengighetsstrukturer
(Master thesis, 2013-03-14)Hovedfokuset i denne oppgaven er å finne gode metoder for modellering av volatilitet og avhengighetsstruktur i finansielle porteføljer. En spesifikk multivariat GARCH modell, Dynamic Conditional Correlation (DCC-) GARCH, ... -
Decay estimates of Green's matrices for discrete-time linear periodic systems
(Journal article; Peer reviewed, 2023)We study periodic Lyapunov matrix equations for a general discrete-time linear periodic system Bpxp−Apxp−1=fp, where the matrix coefficients Bp and Ap can be singular. The block coefficients of the inverse operator of the ... -
Decay of solitary waves of fractional Korteweg-de Vries type equations
(Journal article; Peer reviewed, 2023)We study the solitary waves of fractional Korteweg-de Vries type equations, that are related to the 1- dimensional semi-linear fractional equations: |D|αu + u − f (u) = 0, with α ∈ (0, 2), a prescribed coefficient p∗(α), ... -
Decline in temperature variability on Svalbard
(Journal article; Peer reviewed, 2020)The variability in the temperature on Svalbard, Norway, has been decreasing over the last four decades. This may be due to the reduction in sea ice, transitioning the regional climate to a more stable, coastal one.We ... -

Deep learning-based cross-sensor super resolution of satellite images
(Master thesis, 2021-11-22)Subtitle: Multispectral-to-panchromatic single-image super resolution of GeoEye-1 satellite images using an ESRGAN deep learning model trained exclusively on WorldView-2 images. Abstract: Today, easy and abundant access ... -
Deformations of rational surface singularities and reflexive modules with an application to flops
(Peer reviewed; Journal article, 2018)Blowing up a rational surface singularity in a reflexive module gives a (any) partial resolution dominated by the minimal resolution. The main theorem shows how deformations of the pair (singularity, module) relates to ... -
