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 ... -
Hon som hadde øl å selle. En studie av selvstendig næringsdrivende kvinner bosatt i Strandgaten og Store Markevei i 1865 og 1900
(Master thesis, 2020-06-17)Abstract Female entrepreneurs have existed alongside men for centuries. Despite a large selection of source material, historians have to some extent failed to exploit this topic. Female entrepreneurs have therefore often ... -
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. ... -
Hookworm Infection among Pregnant Women at First Antenatal Visit in Lira, Uganda: A Cross-Sectional Study
(Journal article, 2020)Background: Hookworm infection in expectant mothers has adverse health effects on both the mothers and their unborn babies. Foetal effects are known to include intrauterine growth retardation and physical and mental growth ... -
Hope in action - facing cardiac death: A qualitative study of patients with life-threatening disease
(Peer reviewed; Journal article, 2011-03-18)Coping with existential challenges is important when struck by serious disease, but apart from cancer and palliative care little is known about how patients deal with such issues and maintain hope. To explore how patients ... -
Hopp i havet med hoppekreps
(Årbok for Universitetsmuseet i Bergen;27, Chapter, 2022-12)Hoppekreps (Copepoda) inntar en nøkkelrolle i den marine næringskjeden, og har stor betydning som bindeledd mellom primærproduksjon og høyere trofiske nivåer. Til tross for dette er det fremdeles mange kunnskapshull knyttet ... -
The Hordaland Women's Cohort: A prospective cohort study of incontinence, other urinary tract symptoms and related health issues in middle-aged women
(Peer reviewed; Journal article, 2008-08-23)Background: Urinary incontinence (UI) is a prevalent symptom in middle-aged women, but data on incidence is limited and rarely reported. In order to analyze incidence, remission, or development patterns of severity and ... -
The Hordaland Womens's Cohort. A longitudinal study on urinary incontinence in middle-aged women
(Doctoral thesis, 2014-12-16)Urinary incontinence (UI) is a prevalent problem among middle-aged women, and many epidemiological studies have investigated this problem. Most of these studies are cross-sectional and only few longitudinal studies have ... -
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 ... -
Horizontal and vertical spill-over in multilevel electoral systems
(Journal article; Peer reviewed, 2021)A multilevel electoral system perspective reveals several ways in which electoral spill-over may occur. Vertical spill-over may be top-down from the national to the regional level or can be bottom-up from the regional to ... -
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 ... -
Horizontal plasmid transfer among klebsiella pneumoniae isolates is the key factor for dissemination of extended-spectrum β-lactamases among children in Tanzania
(Journal article; Peer reviewed, 2020)Increased knowledge about the role of horizontal gene transfer is key to improve our understanding of the spread of antimicrobial resistance (AMR) in human populations. We therefore studied the dissemination of the blaCTX-M-15 ... -
Horizontal Reciprocal Radicalization. A comparative analysis of two cases in a Norwegian context
(Master thesis, 2017-12-13)In 2006, Roger Eatwell introduced the concept of “Cumulative Extremism”, after he observed violent clashes between radical right- and radical Islamist groups in Britain. In 2012, their sister groups, Profetens Ummah and ... -

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 receptor loss in endometrial carcinoma curettage predicts lymph node metastasis and poor outcome in prospective multicentre trial
(Peer reviewed; Journal article, 2013-11)Background: Preoperative histologic examination of tumour tissue is essential when deciding if endometrial cancer surgery should include lymph node sampling. We wanted to investigate if biomarkers could improve prediction ... -
Hormone references for ultrasound breast staging and endocrine profiling to detect female onset of puberty
(Journal article; Peer reviewed, 2020)Context Application of ultrasound (US) to evaluate attainment and morphology of glandular tissue provides a new rationale for evaluating onset and progression of female puberty, but currently no hormone references complement ...
