Homeodomain transcription factors Six3 and Six6 have distinct protein binding characteristics
(Doctoral thesis, 2015-02-20)The goal of this study was to characterize Six3 and Six6 proteins interactions and to better understand their functions. The Six class proteins are found in a wide variety of animals ranging from primitive invertebrate ... -
HomologyBasis: Fast Computation of Persistent Homology
(Master thesis, 2021-06-01)Simplicial complexes are used in topological data analysis (TDA) to extract topological features of the data. The HomologyBasis algorithm is proposed as an efficient method for the computation of the topological features ... -
Homotopy analysis of the Lippmann-Schwinger equation for seismic wavefield modeling in strongly scattering media
(Peer reviewed; Journal article, 2020)We present an application of the homotopy analysis method for solving the integral equations of the Lippmann-Schwinger type, which occurs frequently in acoustic and seismic scattering theory. In this method, a series ... -
Homotopy method for seismic modeling in strongly scattering acoustic media with density variation
(Journal article; Peer reviewed, 2020)The wave equation for acoustic media with variable density and velocity can be transformed into an integral equation of the Lippmann-Schwinger type; but for a 4-dimensional state vector involving the gradient of the pressure ... -
Homotopy scattering series for seismic forward modelling with variable density and velocity
(Journal article; Peer reviewed, 2021)We have derived a convergent scattering series solution for the frequency-domain wave equation in acoustic media with variable density and velocity. The convergent scattering series solution is based on the homotopy analysis ... -
Honeycomb Plots: Visual Enhancements for Hexagonal Maps
(Chapter, 2022)Aggregation through binning is a commonly used technique for visualizing large, dense, and overplotted two-dimensional data sets. However, aggregation can hide nuanced data-distribution features and complicates the display ... -
Hook shedding and post-release fate of deep-hooked European eel
(Peer reviewed; Journal article, 2016-07)The European eel (Anguilla anguilla) is a commercially and recreationally important fishery target species. In the last decades, the eel has experienced dramatic stock declines and has been listed as critically endangered. ... -
Horisontkunnskap i aksjon. Om lærernes syn på relevansen av avansert matematisk kunnskap i undervisningsarbeidet
(Master thesis, 2018-06-20)In this master’s thesis I have examined in which ways Norwegian secondary teachers in mathematics think they need advanced mathematical knowledge in their teaching practice, and I have discussed this against the concept ... -
A horizontal Chern–Gauss–Bonnet formula on totally geodesic foliations
(Journal article; Peer reviewed, 2022)Under suitable conditions, we show that the Euler characteristic of a foliated Riemannian manifold can be computed only from curvature invariants which are transverse to the leaves. Our proof uses the hypoelliptic sub-Laplacian ... -
Horizontal holonomy and foliated manifolds
(Journal article; Peer reviewed, 2019)We introduce horizontal holonomy groups, which are groups defined using parallel transport only along curves tangent to a given subbundle D of the tangent bundle. We provide explicit means of computing these holonomy groups ... -
Hormonal and Neuropeptide Mechanisms of Appetite Control in Atlantic Salmon

Hormonal regulation of ovarian follicle growth in humans: Model-based exploration of cycle variability and parameter sensitivities
(Journal article; Peer reviewed, 2022)We present a modelling and simulation framework for the dynamics of ovarian follicles and key hormones along the hypothalamic-pituitary–gonadal axis throughout consecutive human menstrual cycles. All simulation results ... -
Hormone strategies as a key for understanding life history trade-offs in fish
(Doctoral thesis, 2020-04-21)Animal behaviour has fascinated humans for millennia. For studying animal behaviour, evolutionary biologists have focused primarily on their ultimate fitness causes mainly using a top-down approach. In contrast, physiologists ... -
Hormones as adaptive control systems in juvenile fish
(Peer reviewed; Journal article, 2020-02-17)Growth is an important theme in biology. Physiologists often relate growth rates to hormonal control of essential processes. Ecologists often study growth as a function of gradients or combinations of environmental factors. ... -
Host choice and fitness of anemonefish Amphiprion ocellaris (Perciformes: Pomacentridae) living with host anemones (Anthozoa: Actiniaria) in captive conditions
(Peer reviewed; Journal article, 2019)In this study, we investigated the host choice of naïve Amphiprion ocellaris , a specialist, at two different stages of development (newly settling juveniles and post‐settlement juveniles). The fish were exposed to their ... -
Host gill attachment causes blood-feeding by the salmon louse (Lepeophtheirus salmonis) chalimus larvae and alters parasite development and transcriptome
(Journal article; Peer reviewed, 2020-05-06)Background: Blood-feeding is a common strategy among parasitizing arthropods, including the ectoparasitic salmon louse (Lepeophtheirus salmonis), feeding off its salmon host’s skin and blood. Blood is rich in nutrients, ... -
Host specificity and clade dependent distribution of putative virulence genes in Moritella viscosa
(Peer reviewed; Journal article, 2014-12)Moritella viscosa is the aetiological agent of winter-ulcer disease in farmed salmonids in the North Atlantic. Previously, two major (typical and variant) genetic clades have been demonstrated within this bacterial species, ... -
Host-parasite interactions between freshwater pearl mussels (Margaritifera margaritifera) and their salmonid hosts
(Doctoral thesis, 2020-04-29)The freshwater pearl mussel, Margaritifera margaritifera, is an endangered bivalve which has suffered a serious decline across its Holarctic distribution. It has a complex life cycle which involves an obligate parasitic ... -
Hot Vents Beneath an Icy Ocean: The Aurora Vent Field, Gakkel Ridge, Revealed
(Journal article; Peer reviewed, 2022)Evidence of hydrothermal venting on the ultra-slow spreading Gakkel Ridge in the Central Arctic Ocean has been available since 2001, with first visual evidence of black smokers on the Aurora Vent Field obtained in 2014. ... -
How different safety barriers affect the margin between available and required evacuation time
(Master thesis, 2015-06-01)The main purpose of this thesis has been to document that people can evacuate to temporarily safe locations / safe distances during the defined escalating jet fire scenario. It has been important to document that available ...
