Hyperfine Anomaly in Eu Isotopes and the Universiability of the Moskowitz–Lombardi Formula
(Journal article; Peer reviewed, 2020)A method for determining the hyperfine anomaly, without using the nuclear magnetic moments, is used on a series of unstable isotopes of Eu. The large number of experimental data in Eu makes it possible to extract the ... -
Hyperfine structure and hyperfine anomaly in Pb
(Journal article; Peer reviewed, 2018)The hyperfine structure in the 6p 2-configuration in lead has been analysed and the results are compared with calculations. The hyperfine anomaly and improved values of the nuclear magnetic moment for four lead isotopes ... -
Hyperspectral analysis using the correlation between image and reference
(Journal article; Peer reviewed, 2013)We present the use of correlation analysis on spectral data in order to quantify the amount of a given spectrum present with respect to a reference spectrum. The method is shown to be useful in analyzing hyperspectral ... -
Hyperspectral Imaging of In Vitro Wound Models from Human Skin
(Master thesis, 2014)In vitro wounds from human skin have been analysed using hyperspectral imaging. The purpose of this research is to use hyperspectral imaging as a diagnosis tool for skin wounds. The imaging period was 22 days. The images ... -
Hyperspectral Video Analysis by Motion and Intensity Preprocessing and Subspace Autoencoding
(Peer reviewed; Journal article, 2022)Hyperspectral imaging has recently gained increasing attention from academic and industrial world due to its capability of providing both spatial and physico-chemical information about the investigated objects. While this ... -
Hypoxia adapted relative biological effectiveness models for proton therapy: a simulation study
(Peer reviewed; Journal article, 2022)In proton therapy, a constant relative biological effectiveness (RBE) factor of 1.1 is applied although the RBE has been shown to depend on factors including the Linear Energy Transfer (LET). The biological effectiveness ... -
Hypoxia imaging and theranostic potential of [64Cu][Cu(ATSM)] and ionic Cu(II) salts: a review of current evidence and discussion of the retention mechanisms
(Peer reviewed; Journal article, 2020)Background Tumor hypoxia (low tissue oxygenation) is an adverse condition of the solid tumor environment, associated with malignant progression, radiotherapy resistance, and poor prognosis. One method to detect tumor ... -
Hypoxia promotes IL-32 expression in myeloma cells, and high expression is associated with poor survival and bone loss
(Journal article; Peer reviewed, 2017)Multiple myeloma (MM) is a hematologic cancer characterized by expansion of malignant plasma cells in the bone marrow. Most patients develop an osteolytic bone disease, largely caused by increased osteoclastogenesis. The ... -
Høyttalersimulering med mode-basert metode
(Master thesis, 2014)I denne masteroppgaven er det tatt utgangspunkt i modellering av sirkulære horn ved Modal metode som beskrevet i \cite{Kemp}. Denne metoden er blitt videreutviklet til å fungere for konkave, vibrerende strukturer ved at ... -
Ice ridge keel size distributions: Analysis of ice ridge keel thickness from Upward Looking Sonar data from the Fram Strait using extreme value theory.
(Master thesis, 2014)The present thesis explored sea ice ridges in the Fram Strait from data collected at 79 degrees N, 65 degrees W in 2006/2007 by an Upward Looking Sonar instrument, IPS4, and used extreme value analysis to provide an estimate ... -
Identification of novel cyanoacrylate monomers for use in nanoparticle drug delivery systems prepared by miniemulsion polymerisation – A multistep screening approach
(Peer reviewed; Journal article, 2022)Poly (alkyl cyanoacrylate) (PACA) polymeric nanoparticles (NPs) are promising drug carriers in drug delivery. However, the selection of commercially available alkyl cyanoacrylate (ACA) monomers is limited, because most ... -
Identifying Barriers in Extracellular Matrix for Ultrasound-Mediated Delivery of Nanoparticles in 4T1, KPC and CT26 Tumor Models
(Master thesis, 2023)En av utfordringene ved dagens kreftbehandlinger er at kun en liten del av medisinene akkumuleres i svulsten. Man tror noe av grunnen til dette skyldes at den ekstracellulære matriksen (ECM) i svulstvevet er ekstra tettpakket. ... -
Identifying Lagrangian Coherent Structures Using Clustering
(Master thesis, 2018)In these times of rapid environmental changes, our understanding of nature becomes ever more crucial. For example, the spread of oil spills and microplastics can have far reaching consequences for the ecology. Previous ... -
Image Processing of 2-D Snow Images for Cross-Country Skiing
(Master thesis, 2020)Snø er et porøst og komplekst materiale med innflytelse på både vitenskapelige, teknologiske og sosiale arenaer. Dette gjør analyse av snø til en viktig, men krevende oppgave. Tredimensjonal snø analyse gir nøyaktig ... -
Imaging the tumour microenvironment in rectal cancer: Decline in tumour blood flow during radiotherapy predicts good outcome
(Peer reviewed; Journal article, 2023)Background and purpose Measuring rectal tumour response to radiation is pivotal to restaging patients and for possibly stratification to a watch-and-wait strategy. Recognizing the importance of the tumour microenvironment, ... -
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 ... -
