Modeling the diffusion-weighted imaging signal for breast lesions in the b = 200 to 3000 s/mm 2 range: quality of fit and classification accuracy for different representations
(Peer reviewed; Journal article, 2020)Purpose To evaluate different non‐Gaussian representations for the diffusion‐weighted imaging (DWI) signal in the b‐value range 200 to 3000 s/mm2 in benign and malignant breast lesions. Methods Forty‐three patients ... -
Anomalous diffusion in systems with concentration-dependent diffusivity: exact solutions and particle simulations
(Journal article; Peer reviewed, 2020)We explore the anomalous diffusion that may arise as a result of a concentration dependent diffusivity. The diffusivity is taken to be a power law in the concentration, and from exact analytical solutions we show that the ... -
Ultrasound and microbubble treatment for improved delivery of nanomedicine to tumours and the brain
(Doctoral theses at NTNU;2021:138, Doctoral thesis, 2021)The combined use of ultrasound and intravascular microbubbles, referred to as ultrasound and microbubble treatment, has emerged as a promising technique to enhance delivery of nanomedicine to tumours and the brain. Even ... -
Interface Microstructure and Tensile Properties of a Third Generation Aluminium-Steel Butt Weld Produced Using the Hybrid Metal Extrusion & Bonding (HYB) Process
(Peer reviewed; Journal article, 2021)The Hybrid Metal Extrusion & Bonding (HYB) process is a patented solid state joining method for metals which utilizes filler material additions to consolidate the weld. In the present investigation the interface microstructure ... -
3D image guided adaptive brachytherapy in patients with locally advanced cervical cancer: experience and clinical results from a minimum of six years of follow-up
(Peer reviewed; Journal article, 2021)In 2005, individualized 3D image guided brachytherapy was implemented for cervical cancer patients, in accordance with the (GYN) GEC ESTRO recommendation, at St. Olav's Hospital, Trondheim, Norway. This study reports the ... -
Impact of the major SSWs of February 2018 and January 2019 on the middle atmospheric nitric oxide abundance
(Peer reviewed; Journal article, 2021)The Arctic middle atmosphere was affected by major sudden stratospheric warmings (SSW) in February 2018 and January 2019, respectively. In this article, we report for the first time the impact of these two events on the ... -
Sonopermeation Enhances Uptake and Therapeutic Effect of Free and Encapsulated Cabazitaxel
(Peer reviewed; Journal article, 2021)Delivery of drugs and nanomedicines to tumors is often heterogeneous and insufficient and, thus, of limited efficacy. Microbubbles in combination with ultrasound have been found to improve delivery to tumors, enhancing ... -
Effect of nitrogen pressure and substrate bias voltage on the properties of Al–Cr–B–N coatings deposited using cathodic arc evaporation
(Peer reviewed; Journal article, 2021)Cathodic arc evaporation deposition method was applied to forming Al–Cr–B–N coatings. The effect of nitrogen pressure (pN2) and substrate bias voltage (UB) on the properties of the coatings synthesized using Al50Cr30Br20 ... -
A Perturbation Analysis Approach for Studying the Effect of Swelling Kinetics on Instabilities in Hydrogel Plates
(Journal article; Peer reviewed, 2021)The onset of surface instability during diffusion-driven swelling of hydrogels depends on the kinetics of the swelling process. Here, we outline a perturbation analysis framework using a finite difference approach for ... -
Effect of acoustic radiation force on displacement of nanoparticles in collagen gels
(Peer reviewed; Journal article, 2020)Penetration of nanoscale therapeutic agents into the extracellular matrix (ECM) of a tumor is a limiting factor for the sufficient delivery of drugs in tumors. Ultrasound (US) in combination with microbubbles causing ... -
Aging and Failure of a Polymer Chain under Tension
(Peer reviewed; Journal article, 2021)The rupture of a polymer chain maintained at temperature T under fixed tension is prototypical to a wide array of systems failing under constant external stress and random perturbations. Past research focused on analytic ... -
Convergence of Ensemble Simulations for Environmental Risk Assessment
(Chapter, 2017)Ensemble simulations of oil fate and transport for a hypothetical oil spill, sometimes referred to as "stochastic simulations", are frequently used for environmental risk assessment related to offshore operations. In this ... -
Climate Change and Fate of Arctic Oil Spills
(Chapter, 2017)To investigate how the fate of oil released in the Arctic Ocean may change with a warmer climate, we have performed ensembles of oil spill simulations using Arctic environmental information (winds, currents, ice cover, ... -
First-principles study of tensile and shear strength of an Fe2Al5//Fe interface
(Peer reviewed; Journal article, 2021)The interfacial strengths of a low misfit Fe2Al5//Fe interface structure found at aluminum-steel joints has been studied using density functional theory. An interface between Fe and Fe2Al5 was selected based on a criteria ... -
Biological lipid nanotubes and their potential role in evolution
(Peer reviewed; Journal article, 2020)The membrane of cells and organelles are highly deformable fluid interfaces, and can take on a multitude of shapes. One distinctive and particularly interesting property of biological membranes is their ability to from ... -
A technique for in situ X-ray computed tomography of deformation-induced cavitation in thermoplastics
(Peer reviewed; Journal article, 2020)Deformation-induced cavitation influences the mechanical response of polymeric materials, but acquiring in situ measurements of the spatial evolution of cavities has typically necessitated the use of synchrotron radiation ... -
Smart cancer nanomedicine
(Peer reviewed; Journal article, 2019)Nanomedicines are extensively employed in cancer therapy. We here propose four strategic directions to improve nanomedicine translation and exploitation. (1) Patient stratification has become common practice in oncology ... -
