(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 ...

(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 ...

3D-characterization of deuterium distributions in zirconium oxide scale using high-resolution SIMS (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In pressurised water reactors (PWRs), fuel rods are clad with zirconium alloy tubes chosen for their low neutron capture cross section and good oxidation resistance. Understanding cladding-water corrosion reactions at ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Background: The rapid neutron capture process is one of the main nucleosynthesis processes of elements heavier than Fe. Uncertainties in nuclear properties, such as masses, half-lives, and β -delayed neutron probabilities ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)In this article, a low-power, radiation-hard front-end circuit for monolithic pixel sensors, designed to meet the requirements of low noise and low pixel-to-pixel variability, the key features to achieve high detection ...
-
A circuit for simultaneous measurements of skin electrical conductance, susceptance, and potential (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)A circuit is presented that enables measurement of skin electrical conductance, susceptance, and potential simultaneously beneath the same monopolar electrode. Example measurements are shown to confirm the function of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)This work demonstrates how a multi-electrode array (MEA) dedicated to four-electrode bioimpedance measurements can be implemented on a complementary metal–oxide–semiconductor (CMOS) chip. As a proof of concept, an 8 × 8 ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2020)The phase-field crystal model in an amplitude equation approximation is shown to provide an accurate description of the deformation field in defected crystalline structures, as well as of dislocation motion. We analyze in ...

A common [18F]-FDG PET radiomic signature to predict survival in patients with HPV-induced cancers (Journal article / Tidsskriftartikkel / SubmittedVersion, 2023)Locally advanced cervical cancer (LACC) and anal and oropharyngeal squamous cell carcinoma (ASCC and OPSCC) are mostly caused by oncogenic human papillomaviruses (HPV). In this paper, we developed machine learning (ML) ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Pituitary endocrine cells fire action potentials (APs) to regulate their cytosolic Ca2+ concentration and hormone secretion rate. Depending on animal species, cell type, and biological conditions, pituitary APs are generated ...
