Multi-generation genetic and fitness effects of immigration in a natural meta-population of song sparrows (Melospiza melodia)
(Doctoral theses at NTNU;2024:105, Doctoral thesis, 2024)Fragmentation leads to smaller habitat patches and population sizes, endangering population fitness and persistence, including through inbreeding depression and loss of genetic diversity. These effects can be mitigated ... -
Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validation
(Journal article; Peer reviewed, 2023)Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reli-ability of those predictions, they need to be critically ... -
Subclinical thiamine deficiency results in failed reproduction in Arctic foxes
(Peer reviewed; Journal article, 2024)Thiamine deficiency can result in life-threatening physiological and neurological complications. While a thiamine-deficient diet may result in the onset of such symptoms, the presence of thiaminase – an enzyme that breaks ... -
Electrochemically Assisted Growth of Hopper and Tabular Calcite under Confinement
(Peer reviewed; Journal article, 2024)Crystallization under confinement is commonplace in nature and offers new pathways to engineer crystals with the desired morphologies in a controlled and reproducible manner. In this work, we demonstrate the electrochemically ... -
Sorption-enhanced Fischer-Tropsch synthesis – Effect of water removal
(Peer reviewed; Journal article, 2024)The Sorption-Enhanced Fischer-Tropsch synthesis (SEFTS), with water removal by means of a solid sorbent, has been demonstrated for the first time experimentally. Commercial water sorbents (Zeolites type 13X and 4 A) were ... -
Flexible Transparent Electrodes Formed from Template-Patterned Thin-Film Silver
(Peer reviewed; Journal article, 2023)Template-patterned, flexible transparent electrodes (TEs) formed from an ultrathin silver film on top of a commercial optical adhesive – Norland Optical Adhesive 63 (NOA63) – are reported. NOA63 is shown to be an effective ... -
Electronic Property Engineering in a Ferroelectric Oxide: Nanostructuring and Advanced Characterization.
(Doctoral theses at NTNU;2024:102, Doctoral thesis, 2024)The advancement of electronic nanotechnology hinges on the use of innovative materials and new conceptual approaches for devices to meet the demand of miniaturization, energy efficiency, and sustainability. Ferroelectric ... -
Scanning precession electron diffraction data analysis approaches for phase mapping of precipitates in aluminium alloys
(Peer reviewed; Journal article, 2023)Mapping the spatial distribution of crystal phases with nm-scale spatial resolution is an important characterisation task in studies of multi-phase materials. One popular approach is to use scanning precession electron ... -
Self-Optimizing Control of an Offshore Blue Hydrogen Plant
(Master thesis, 2023)Utviklingen av fornybare energikilder øker stadig, men ytterligere fremgang er nødvendig. Oppdagelsen av nye metoder for å produsere miljøvennlig drivstoff og energikilder er avgjørende, med hydrogen som et lovende alternativ. ... -
Understanding the inoculation of aluminium grains during welding under the influences of high cooling rate and high temperature gradient
(Peer reviewed; Journal article, 2023)Inoculation is an important method to generate fine equiaxed grain structures in alloys during solidification, which is widely used in shape casting and direct chill casting processes of aluminium alloys. Different from ... -
Advances in Optimisation and Machine Learning for Process Systems Engineering
(Doctoral theses at NTNU;2024:85, Doctoral thesis, 2024)Optimisation is a valuable tool in process systems engineering, and has been widely used in design, control, process identification and many other areas. This thesis proposes novel applications of optimisation, as well as ... -
Toward a pulsed antihydrogen beam for WEP tests in AEgIS
(Peer reviewed; Journal article, 2023)The AEg̅IS collaboration at CERN’s AD produces antihydrogen atoms in the form of a pulsed, isotropic source with a precisely defined formation time. AEg̅IS has recently undergone major upgrades to fully benefit from the ... -
Exploring the Intersection of Brain–Computer Interfaces and Quantum Sensing: A Review of Research Progress and Future Trends
(Peer reviewed; Journal article, 2023)Brain–computer interfaces (BCIs) can revolutionize how humans interact with technology, but several scientific and technological challenges must be addressed to realize their full potential. Recent developments in quantum-based ... -
β-(1 → 3)(1 → 6)glucan from Schizophyllum commune 227E.32: High yield production via glucose/xylose co-metabolization
(Peer reviewed; Journal article, 2023)A co-metabolization of xylose and glucose by Schizophyllum commune 227E.32 wild mushroom for exopolysaccharide (EPS) production is presented. Cultivations performed with S. commune 227E.32 at different xylose concentrations ... -
Detecting ALP wiggles at TeV energies
(Peer reviewed; Journal article, 2024)Axions and axion-like-particles (ALPs) are characterised by their two-photon coupling, which entails so-called photon-ALP oscillations as photons propagate through a magnetic field. These oscillations lead to distinctive ... -
