Hydrothermal vent fields and chemosynthetic biota on the world's deepest seafloor spreading centre
(Journal article, 2012-01-10)The Mid-Cayman spreading centre is an ultraslow-spreading ridge in the Caribbean Sea. Its extreme depth and geographic isolation from other mid-ocean ridges offer insights into the effects of pressure on hydrothermal ... -
HyperHMM: efficient inference of evolutionary and progressive dynamics on hypercubic transition graphs
(Journal article; Peer reviewed, 2023)Motivation: The evolution of bacterial drug resistance and other features in biology, the progression of cancer and other diseases and a wide range of broader questions can often be viewed as the sequential stochastic ... -
HyperTraPS: Inferring probabilistic patterns of trait acquisition in evolutionary and disease progression pathways
(Peer reviewed; Journal article, 2020)The explosion of data throughout the biomedical sciences provides unprecedented opportunities to learn about the dynamics of evolution and disease progression, but harnessing these large and diverse datasets remains ... -
Hypothalamic agrp and pomc mRNA Responses to Gastrointestinal Fullness and Fasting in Atlantic Salmon (Salmo salar, L.)
(Journal article; Peer reviewed, 2020-02-11)The orexigenic agouti-related protein (AgRP) and the anorexigenic pro-opiomelanocortin (POMC) are crucial players in the control of feed intake in vertebrates, yet their role in teleosts has not been fully established. ... -
Hypoxia adapted relative biological effectiveness models for proton therapy: a simulation study
(Journal article; Peer reviewed, 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 tolerance and responses to hypoxic stress during heart and skeletal muscle inflammation in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2017-07-11)Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed ... -
Hypoxia tolerance thresholds for post-smolt Atlantic salmon: Dependency of temperature and hypoxia acclimation
(Journal article, 2013-12-05)Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O2) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), ... -
«Hæh? Er det der en modell liksom?» Ei studie av R2 elevar si oppfatning av læringsutbyttet ved eit didaktisk kontraktbrot.
(Master thesis, 2017-07-26)Matematikkundervisning i Noreg følgjer stort sett same didaktiske kontrakt. Korleis opplever elevar med full fordjuping i faget eit brot på denne kontrakten? Studia baserer seg på to teoretiske fundament: Det teoretiske ... -
Høyfrekvens finans og markedets mikrostruktur på Oslo Børs
(Master thesis, 2009-09-09)Høyfrekvens finans, som er tema for denne oppgaven, tar for seg studiet av høyfrekvente finansielle data. I denne oppgaven har vi sett på data med den høyest mulige frekvensen, nemlig data fra hver eneste handel. De ... -
Høyoppløselig rekonstruksjon av brefluktuasjoner på Fastdalstindbreen gjennom holosen. En studie basert på kvartærgeologisk kartlegging og analyse av innsjøsedimenter fra Elvejordsvatnet, Lyngen, Nord-Norge
(Master thesis, 2012-06-01)Fastdalstindbreen is a ~0, 16 km2 lager cirque glacier below the mountain Fastdalstind in Lyngen, Northern Norway. Cirque glaciers can be sensitive indicators of change in temperature, precipitation or wind direction. ... -
I Can See Clearly Now: Clairvoyant Assertions for Deadlock Checking
(Journal article; Peer reviewed, 2022)Static analysers are traditionally used to check various correctness properties of software. In the face of refactorings that can have adverse effects on correctness, developers need to analyse the code after refactoring ... -
Ice and brine production in Hornsund
(Master thesis, 2015-06-02)The Hornsund fjord system has been studied using observations of the atmosphere, ocean and sea ice, and two different types of models. The study documents significant year to year variability in sea ice formation and brine ... -
The ice front as a topographic barrier for ocean heat transport
(Doctoral thesis, 2021-06-28)Antarctic ice shelves are the link between the Southern Ocean and the Antarctic Ice Sheet. The floating ice shelves restrain the seaward flow of the grounded ice, which is balanced by iceberg calving and ocean-induced basal ... -
Ice sheets, oceanic circulation & sea surface conditions: the NW European margin during the last 35,000 years
(Doctoral thesis, 2018-04-20)The north-western European continental margin provides a key area for detailed investigations of changes within the inflow of Atlantic warm surface currents, fluctuations in continental ice sheets and the corresponding ... -
Ice shelf water overflow and bottom water formation in the southern Weddell Sea
(Peer reviewed; Journal article, 2004-02-17)Cold shelf waters flowing out of the Filchner Depression in the southern Weddell Sea make a significant contribution to the production of Weddell Sea Bottom Water (WSBW), a precursor to Antarctic Bottom Water (AABW). We ... -
Ice Thickness and Bed Elevation of the Northern and Southern Patagonian Icefields
(Peer reviewed; Journal article, 2019)The Northern and Southern Patagonian Icefields are the largest ice masses in the Southern Hemisphere outside Antarctica, but their ice volume and bed topography are poorly known. Here, we combine airborne gravity data ... -
Ice-algal carbon supports harp and ringed seal diets in the European Arctic: evidence from fatty acid and stable isotope markers
(Journal article; Peer reviewed, 2021)Sea-ice declines in the European Arctic have led to substantial changes in marine food webs. To better understand the biological implications of these changes, we quantified the contributions of ice-associated and pelagic ... -
