(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)10-VE A≡A′ Diatomics, such as N≡N, C≡O, etc., have a strong σ2π4 triple bond plus a lone pair at each end. In our studies on 14-VE A≡B systems, such as C≡Pt, we find a similar bonding system plus a (5dδ)4 ring. Here, the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract. Geodynamic modelling provides a powerful tool to investigate processes in the Earth's crust, mantle, and core that are not directly observable. However, numerical models are inherently subject to the assumptions ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The nuclear level densities and γ-ray strength functions of 138,139,140La were measured using the 139La(3He,α), 139La(3He,'3He), and 139La(d,p) reactions. The particle-γ coincidences were recorded with the silicon particle ...

(Master thesis / Masteroppgave, 2009)I denne masteroppgaven ble det sett på sammenhenger mellom vitenskapelige data som er tilgjengelige og bruken av 14 tradisjonelle medisinplanter, med fokus på lakserende effekt. Plantene er hentet fra Burma-samlingen som ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)We present a unique time series of continuous glacier frontal ablation rates with weekly resolution over 15 years estimated from seismic calving observations at Kronebreen, Svalbard. Using linear statistical models, we ...
-
(Master thesis / Masteroppgave, 2008)Alzheimers sykdom, Parkinsons sykdom og hjerneslag er assosiert med nevrodegenerering i visse deler av hjernen. Overstimulering av glutamatreseptorer med medfølgende produksjon av frie radikaler har blitt foreslått å være ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We have investigated optically excited magnetoelastic waves by phase-resolved spin-wave tomography (PSWaT). PSWaT reconstructs the dispersion relation of spin waves together with their phase information by using time-resolved ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Introduction Degeneration of dopaminergic, nigrostriatal neurons is the hallmark of Parkinson disease (PD), and PET quantification of dopamine transporters is a widely accepted method for differential diagnosis between ...

(Research report / Forskningsrapport, 1997)Given a graph G with a specified root node r. A spanning tree in G where each node has distance at most 2 from r is called a 2-hop spanning tree. For given edge weights the 2-hop spanning tree problem is to find a minimum ...
-
(Master thesis / Masteroppgave, 2006)In the recent years the focus and interest for wireless networks has been increasing. However, it is the security mechanisms (or lack of so) that has caught most people's attention. This is mostly well-deserved criticism ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Introduction: Management of patients with brain metastases is often based on manual lesion detection and segmentation by an expert reader. This is a time- and labor-intensive process, and to that end, this work proposes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)A low-power on-off-keying impulse-radio (IR) ultra-wideband (UWB) pulse generator (PG) intended for wireless-powered IR-UWB radio applications is presented. The proposed PG has high flexibility, the center frequency, output ...
