Local versus Equal Load Sharing in the Fiber Bundle Model
(Doctoral theses at NTNU;2019:368, Doctoral thesis, 2019)Fracture is a huge field of research that includes physics, geology, materials science, and engineering. Most approaches are very specialized, but what if we instead want to focus on the big picture to look for general ... -
Antiferromagnetic Insulator Spintronics
(Doctoral theses at NTNU;2019:343, Doctoral thesis, 2019)Summary: Spin currents can make your computer energy efficient and ultrafast Have you noticed that your laptop sometimes can get quite warm? Electronical devices rely on transfer of information via a charge current ... -
In-situ observations of dislocation recovery and low angle boundary formation in deformed aluminium
(Journal article; Peer reviewed, 2019)An experimental study of the recovery of dislocations and low angle boundary formation in aluminium is presented. By combining in-situ annealing with orientation mapping in the transmission electron microscope, maps of ... -
Comparison of Intravoxel incoherent motion imaging and multiecho dynamic contrast-based MRI in rectal cancer
(Journal article; Peer reviewed, 2019)Background Dynamic contrast‐based MRI and intravoxel incoherent motion imaging (IVIM) MRI are both methods showing promise as diagnostic and prognostic tools in rectal cancer. Both methods aim at measuring perfusion‐related ... -
Magneto-dynamic properties of complex oxide—La0.7Sr0.3MnO3/SrTiO3— heterostructure interface
(Journal article; Peer reviewed, 2019)We have studied the interface magnetodynamic properties of La0.7Sr0.3MnO3/SrTiO3 (111) heterostructures by Ferromagnetic resonance spectroscopy (FMR). In addition to the bulk FMR mode, the measurements indicate a mode ... -
Local structure of Ca2+ alginate hydrogels gelled via competitive ligand exchange and measured by small angle X-ray scattering
(Journal article; Peer reviewed, 2019)Alginates, being linear anionic co-polymers of 1,4-linked residues β-d-ManA (M) and α-l-GulA (G), are widely applied as hydrogel biomaterials due to their favourable in vivo biocompatibility and convenient ionic crosslinking. ... -
Single crystal semiconductor-core optical fiber*
(Journal article; Peer reviewed, 2019)Semiconductor-core fibers are improved by removal of grain boundaries. We use a CO2 laser to process silicon-based cores; an alloying element reduces both the temperature and speed required for formation of a single crystal. -
FIB lift-out of conducting ferroelectric domain walls in hexagonal manganites
(Journal article; Peer reviewed, 2019)A focused ion beam (FIB) methodology is developed to lift out suitable specimens containing charged domain walls in improper ferroelectric ErMnO3. The FIB procedure allows for extracting domain wall sections with well-defined ... -
High level of circulating vitamin D during neoadjuvant therapy may lower risk of metastatic progression in high-risk rectal cancer
(Journal article; Peer reviewed, 2019)Background:Following curative-intent neoadjuvant therapy in locally advanced rectal cancer, metastaticprogression is still dominant. We investigated if patients’circulating 25-hydroxyvitamin D [25(OH)D] levels wereassociated ... -
Immunogenic cell death by neoadjuvant oxaliplatin and radiation protects against metastatic failure in high-risk rectal cancer.
(Journal article; Peer reviewed, 2019)Objective High rates of systemic failure in locally advanced rectal cancer call for a rational use of conventional therapies to foster tumor-defeating immunity. Methods We analyzed the high-mobility group box-1 ... -
The effect of heavy deformation on the precipitation in an Al-1.3Cu-1.0Mg-0.4Si wt.% alloy
(Journal article; Peer reviewed, 2020)This work has investigated the effect of the combination of natural ageing and 80% pre-deformation after solution heat treatment on precipitation during subsequent artificial ageing in an Al-1.3Cu-1.0Mg-0.4Si wt.% alloy. ... -
Students' Critical Perceptions About Mathematics Education
(Chapter, 2019)This paper presents excerpts from 10 semi-structured interviews conducted with 8th and 9th grade students in a Norwegian countryside school. Interviews were conducted to gain an insight into students' potential to critically ... -
The effect of low Cu additions on precipitate crystal structures in overaged Al-Mg-Si(-Cu) alloys
(Journal article; Peer reviewed, 2020)This study concerns the effect of low Cu additions (<0.1 at.%) on the precipitate crystal structure evolution in three Al-Mg-Si(-Cu) alloys during overageing. The evolution was assessed through a combination of atomic ... -
Assessment of Articular Cartilage by Second Harmonic Microscopy: Challenges and Opportunities
(Journal article; Peer reviewed, 2019)Second harmonic microscopy (SHM) has emerged as a powerful non-destructive optical imaging modality that has high potential to perform the advanced structural characterization of intact articular cartilage. This article ... -
Airglow Derived Measurements of Q-Branch Transition Probabilities for Several Hydroxyl Meinel Bands
(Journal article; Peer reviewed, 2019)Spectroscopic measurements of the hydroxyl (OH) airglow emissions are often used to infer neutral temperatures near the mesopause. Correct Einstein coefficients for the various transitions in the OH airglow are needed to ... -
Ultrafast nonlocal collective dynamics of Kane plasmon-polaritons in a narrow-gap semiconductor
(Journal article; Peer reviewed, 2019)The observation of ultrarelativistic fermions in condensed-matter systems has uncovered a cornucopia of novel phenomenology as well as a potential for effective ultrafast light engineering of new states of matter. While ... -
Three-dimensional study of nodule clustering and heterogeneous strain localization for tailored material properties in ductile iron
(Journal article; Peer reviewed, 2019)Tailored heterogeneous distributions of microstructural features enable extraordinary material performance in biological and physiological structures such as trees, the aortic arch, human teeth and dinosaur skulls. In ... -
Role of protein self-association on DNA condensation and nucleoid stability in a bacterial cell model
(Journal article; Peer reviewed, 2019)Bacterial cells do not have a nuclear membrane that encompasses and isolates the genetic material. In addition, they do not possess histone proteins, which are responsible for the first levels of genome condensation in ... -
Transition from Galactic to Extragalactic Cosmic Rays
(Journal article; Peer reviewed, 2019)The question at which energy the transition from Galactic to extragalactic cosmic rays takes place has been a long-standing conundrum in cosmic ray physics. In the past, the transition energy has been usually associated ... -
Gamma-ray counterpart of the IceCube neutrinos
(Journal article; Peer reviewed, 2019)A γ-ray excess at high Galactic latitudes starting at energies 300 GeV was recently discovered in the data of the Fermi telescope. The multi-TeV γ-ray emission found has spectral characteristics at both low and high Galactic ...
