Effects of positive end-expiratory pressure on cerebral hemodynamics in acute brain injury patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-02)Background: Cerebral autoregulation is the mechanism that allows to maintain the stability of cerebral blood flow despite changes in cerebral perfusion pressure. Maneuvers which increase intrathoracic pressure, such as the application of positive end-expiratory pressure (PEEP), have been always challenged in brain injured patients for the risk of increasing intracranial pressure (ICP) and altering ... -
Quantum cluster equilibrium prediction of liquid ethanol
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-17)Quantum cluster equilibrium theory (QCE) has been widely used to determine the properties of pure and binary mixture of liquids. The main limitation of the application of QCE is the exploration of different possible clusters formed by the solvent molecules. Therefore, in this study, we applied the QCE theory to predict liquid properties of ethanol after thorough exploration of the potential energy ... -
Microsolvation of phenol in water: structures, hydration free energy and enthalpy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-05)In this work, we have studied the microsolvation of phenol in water. We started by identifying initial configurations of phenol-water clusters using classical molecular dynamics. The configurations are optimised at the ωB97XD/aug-cc-pVDZ level of theory. To understand the interaction between phenol and the solvating water molecules, we performed a quantum theory of atoms in molecules (QTAIM) analysis. ... -

Transferability of graph neural networks: An extended graphon approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-28)We study spectral graph convolutional neural networks (GCNNs), where filters are defined as continuous functions of the graph shift operator (GSO) through functional calculus. A spectral GCNN is not tailored to one specific graph and can be transferred between different graphs. It is hence important to study the GCNN transferability: the capacity of the network to have approximately the same ... -
Real-Time Outdoor Localization Using Radio Maps: A Deep Learning Approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)Global Navigation Satellite Systems typically perform poorly in urban environments, where the likelihood of line-of-sight conditions between devices and satellites is low. Therefore, alternative location methods are required to achieve good accuracy. We present LocUNet: A convolutional, end-to-end trained neural network (NN) for the localization task, which is able to estimate the position of a user ... -

Ofret Nansen vitenskapen for freden?
(Chapter; Bokkapittel, 2023)Da Fridtjof Nansen døde i 1930, skrev Nordahl Grieg hjem til sin bror Harald Grieg: «For et eventyrlig liv som er forbi, det var jo ikke én stor mand som døde, det var ti». Nansens brede virke, hans mange evner, hans tilstedeværelse i store hendelser gir alt et voldsomt inntrykk – og har gitt ham mange merkelapper: vitenskapsmann, polfarer, kunstner, diplomat, filantrop, for å nevne noen. <p> <p>Det ... -
