DeepOtolith v1.0: An Open-Source AI Platform for Automating Fish Age Reading from Otolith or Scale Images
(Journal article; Peer reviewed, 2022-05-29)Every year, marine scientists around the world read thousands of otolith or scale images to determine the age structure of commercial fish stocks. This knowledge is important for fisheries and conservation management. ... -
Restricted maximum-likelihood method for learning latent variance components in gene expression data with known and unknown confounders
(Journal article; Peer reviewed, 2022)Random effects models are popular statistical models for detecting and correcting spurious sample correlations due to hidden confounders in genome-wide gene expression data. In applications where some confounding factors ... -
Substantial Sparing of Organs at Risk with Modern Proton Therapy in Lung Cancer, but Altered Breathing Patterns Can Jeopardize Target Coverage
(Journal article; Peer reviewed, 2022-03-08)Enhancing treatment of locally advanced non-small cell lung cancer (LA-NSCLC) by using pencil beam scanning proton therapy (PBS-PT) is attractive, but little knowledge exists on the effects of uncertainties occurring between ... -
Integrating Multidisciplinary Observations in Vent Environments (IMOVE): Decadal Progress in Deep-Sea Observatories at Hydrothermal Vents
(Journal article; Peer reviewed, 2022-05-13)The unique ecosystems and biodiversity associated with mid-ocean ridge (MOR) hydrothermal vent systems contrast sharply with surrounding deep-sea habitats, however both may be increasingly threatened by anthropogenic ... -
High prevalence of Ichthyophonus sp. infections in Northeast Atlantic mackerel (Scomber scombrus)
(Journal article; Peer reviewed, 2022) -
Developmental stages of the ballan wrasse from first feeding through metamorphosis: Cranial ossification and the digestive system
(Journal article; Peer reviewed, 2022)We have described six developmental stages for the ballan wrasse, from the first feeding until the juvenile stage, supported by specific descriptions of cranial ossification, maturation of the digestive tract, and ... -
On the Sombor characteristic polynomial and Sombor energy of a graph
(Journal article; Peer reviewed, 2022)Let G be a simple graph with vertex set V(G)={v1,v2,…,vn}. The Sombor matrix of G, denoted by ASO(G), is defined as the n×n matrix whose (i, j)-entry is d2i+d2j−−−−−−√ if vi and vj are adjacent and 0 for another cases. Let ... -
Introduction to total dominator edge chromatic number
(Journal article, 2022)We introduce the total dominator edge chromatic number of a graph G. A total dominator edge coloring (briefly TDE-coloring) of G is a proper edge coloring of G in which each edge of the graph is adjacent to every edge of ... -
Machine learning approaches for high-dimensional genome-wide association studies
(Doctoral thesis, 2022-08-24)Formålet med Genome-wide association studies (GWAS) er å finne statistiske sammenhenger mellom genetiske varianter og egenskaper av interesser. De genetiske variantene som forklarer mye av variasjonene i genomfattende ... -
Threshold estimation based on local minima for nucleus and cytoplasm segmentation
(Journal article; Peer reviewed, 2022)Background Image segmentation is the process of partitioning an image into separate objects or regions. It is an essential step in image processing to segment the regions of interest for further processing. We propose a ... -
Long-term trends in diatom diversity and palaeoproductivity: A 16 000-year multidecadal record from Lake Baikal, southern Siberia
(Journal article; Peer reviewed, 2022)Biological diversity is inextricably linked to community stability and ecosystem functioning, but our understanding of these relationships in freshwater ecosystems is largely based on short-term observational, experimental, ... -
60 years of scientific deep drilling in Colombia: The north Andean guide to the Quaternary
(Journal article; Peer reviewed, 2022)We sketch the initial history of collecting deep cores in terrestrial and marine sedimentary basins and ice cores to study environmental and climate change. Subsequently, we focus on the development of long records from ... -
Bedymo: A combined quasi-geostrophic and primitive equation model in σ coordinates
(Journal article; Peer reviewed, 2022)This paper introduces the Bergen Dynamical Model (Bedymo), an idealized atmospheric circulation model, which combines the quasi-geostrophic approximation and the hydrostatic primitive equations into one modelling framework. ... -
Wave response to an arbitrary motion of a load on an ice plate
(Master thesis, 2022-06-22) -
Lignin Preservation and Microbial Carbohydrate Metabolism in Permafrost Soils
(Journal article; Peer reviewed, 2022)Permafrost-affected soils in the northern circumpolar region store more than 1,000 Pg soil organic carbon (OC), and are strongly vulnerable to climatic warming. However, the extent to which changing soil environmental ... -
Geochemistry of hydrothermal fluids from the E2-segment of the East Scotia Ridge: Magmatic input, reaction zone processes, fluid mixing regimes and bioenergetic landscapes
(Journal article; Peer reviewed, 2022)The compositions of hydrothermal fluids in back-arc basins (BABs) can be affected by the influx of magmatic fluids into systems that are dominated by reactions between basement rocks and seawater-derived fluids. The East ... -
High abundances of small copepods early developmental stages and nauplii strengthen the perception of a non-dormant Arctic winter
(Journal article; Peer reviewed, 2022)The traditional view is that the Arctic polar night is a quiescent period for marine life, but recent reports of high levels of feeding and reproduction in both pelagic and benthic taxa have challenged this. We examined ... -
Pore-scale bubble population dynamics of CO2-foam at reservoir pressure
(Journal article; Peer reviewed, 2022)The flow of CO2 foam for mobility control in porous media is dictated by the foam texture, or bubble density, which is commonly expressed as the number of bubbles per unit of flowing gas. In most high-pressure laboratory ... -
Multidecadal variability of ENSO in a recharge oscillator framework
(Journal article; Peer reviewed, 2022)We use a conceptual recharge oscillator model to identify changes in El Niño and the Southern Oscillation (ENSO) statistics and dynamics during the observational record. The variability of ENSO has increased during the ... -
The Nuclear Pore Complex: Birth, Life, and Death of a Cellular Behemoth
(Journal article; Peer reviewed, 2022)Nuclear pore complexes (NPCs) are the only transport channels that cross the nuclear envelope. Constructed from ~500–1000 nucleoporin proteins each, they are among the largest macromolecular assemblies in eukaryotic cells. ...
