Refined notions of parameterized enumeration kernels with applications to matching cut enumeration
(Journal article; Peer reviewed, 2021)An enumeration kernel as defined by Creignou et al. (2017) [11] for a parameterized enumeration problem consists of an algorithm that transforms each instance into one whose size is bounded by the parameter plus a ... -
Refinement of a radioreceptor binding assay for nicotinic acid adenine dinucleotide phosphate
(Peer reviewed; Journal article, 2007-12-01)The measurement of changes in nicotinic acid adenine dinucleotide phosphate (NAADP) levels in cells has been, and remains, key to the investigation of the functions of NAADP as a Ca2+-releasing second messenger. Here we ... -
Refining benthic foraminiferal Mg/Ca-temperature calibrations using core-tops from the western tropical Atlantic: Implication for paleotemperature estimation
(Peer reviewed; Journal article, 2013-04)Benthic foraminiferal Mg/Ca has been shown to have great potential as a proxy for reconstructing deep water temperatures. However, the exact relationship between Mg uptake in benthic foraminifera and temperature is still ... -
Refining Greenland geothermal heat flux through stable isotope analysis
(Master thesis, 2023-03-30)Geothermal heat flux is an important control on the dynamics of glaciers and ice sheets. In Greenland however, only few direct observations of geothermal heat flux exist. The exact spatial distribution and magnitude of ... -
Reflections on Courses for Software Language Engineering
(Journal article; Peer reviewed, 2014)Software Language Engineering (SLE) has emerged as a field in computer science research and software engineering, but it has yet to become entrenched as part of the standard curriculum at universities. Many places have a ... -
Reflections on the Use of Ecological Attributes and Traits in Quaternary Botany
(Journal article; Peer reviewed, 2020)There has been an upsurge of interest and research activity in trait-based approaches in ecology, biogeography, and macroecology. I discuss if this upsurge has impacted Quaternary botany (the study of plant remains preserved ... -
The refractive and diffractive contributions to GPS signal scintillation at high latitudes during the geomagnetic storm on 7-8 September 2017
(Journal article; Peer reviewed, 2022)Different indices have been used to reflect, or monitor the ionospheric scintillation, e.g. the detrended carrier phase, σφ, S4, the rate of change of the vertical total electron content index (vROTI), as well as the ... -
A Regime View of ENSO Flavors Through Clustering in CMIP6 Models
(Journal article; Peer reviewed, 2023)El Niño-Southern Oscillation (ENSO) flavors in the tropical Pacific are studied from a regime perspective. Five recurring spatial patterns or regimes characterizing the diversity of ENSO are established using a clustering ... -
Regional atmospheric response to the Benguela Niñas
(Journal article; Peer reviewed, 2021)We investigate how the atmosphere is affected by the cold sea surface temperature (SST) anomalies of the Benguela Niñas using reanalysis data and a high-resolution atmospheric model. A composite analysis of reanalysis data ... -
Regional climate model simulations for Europe at 6k and 0.2k years BP: sensitivity to changes in anthropogenic deforestation
(Peer reviewed; Journal article, 2014-03-28)This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, ~6 and ~0.2 k BP in Europe. We apply We apply the Rossby Centre regional climate ... -
Regional climate models' performance in representing precipitation and temperature over selected Mediterranean areas
(Peer reviewed; Journal article, 2013-12-12)This paper discusses the relative performance of several climate models in providing reliable forcing for hydrological modeling in six representative catchments in the Mediterranean region. We consider 14 Regional Climate ... -
Regional correlation and seismic stratigraphy of Triassic Strata in the Greater Barents Sea: implications for sediment transport in Arctic basins
(Journal article; Peer reviewed, 2020)The Greater Barents Sea Basin (GBSB) in Arctic Russia and Norway is an intracratonic basin that accommodated an enormous amount of sediment during the Triassic. These deposits are up to 4.5 km thick over an area 2,500,000 ... -
Regional Expression of npy mRNA Paralogs in the Brain of Atlantic Salmon (Salmo salar, L.) and Response to Fasting
(Journal article; Peer reviewed, 2021-08-26)Neuropeptide Y (NPY) is known as a potent orexigenic signal in vertebrates, but its role in Atlantic salmon has not yet been fully established. In this study, we identified three npy paralogs, named npya1, npya2, and npyb, ... -
Regional impact from fin-fish farming in an intensive production area (Hardangerfjord, Norway)
(Peer reviewed; Journal article, 2014)The Hardangerfjord is one of the largest salmon-farming areas in Norway, with an annual production of approximately 70,000 metric tonnes. The regional impact of fin-fish farming in a fjord environment was studied during ... -
Regional, seasonal, and predictable Arctic sea ice change
(Doctoral thesis, 2017-12-07)The loss of Arctic sea ice is one of the most prominent and best quantified indicators of ongoing global climate change. Satellite passive microwave observations since 1979 indicate significant negative sea ice extent ... -
Regresjonsmodeller i skipsforsikring
(Master thesis, 2009-09-15)Masteroppgaven tar utgangspunkt i et datasett fra skipsforsikring og undersøker hva slags modeller som passer til skadefrekvensen for dette datasettet. Hovedfokuset for masteroppgaven vil være på generalisert lineært miksede ... -
Regular Expressions with Numerical Constraints and Automata with Counters
(Lecture Notes in Computer Science, Chapter; Peer reviewed, 2009)Regular expressions with numerical constraints are an extension of regular expressions, allowing to bound numerically the number of times that a subexpression should be matched. Expressions in this extension describe the ... -
Regulation of appetite and growth of Atlantic salmon (Salmo salar L.) and effect of water oxygen, temperature and dietary energy
(Doctoral thesis, 2017-06-27)High water temperature combined with low dissolved oxygen (LO or hypoxia) is one of the most challenging environmental conditions farmed fish experience. The oxygen requirement of fish increases in parallel to this, which ... -
Regulation of defective mitochondrial DNA accumulation and transmission in C. elegans by the programmed cell death and aging pathways
(Journal article; Peer reviewed, 2023)The heteroplasmic state of eukaryotic cells allows for cryptic accumulation of defective mitochondrial genomes (mtDNA). ‘Purifying selection’ mechanisms operate to remove such dysfunctional mtDNAs. We found that activators ...
