Dowker Duality
(Master thesis, 2023-06-01) -
Dowker’s Theorem by Simplicial Sets and a Category of 0-Interleavings
(Master thesis, 2019-06-21)In this thesis we look at an alternative proof of Dowker’s theorem [4] using simplical sets. We prove the strongest version of the theorem [3], which can be applied to persistence homology in the sense that every nested ... -
Down-dip correlation and modelling of shallow-marine and estuarine deposits in the Sunnyside Member, Book Cliffs, Eastern Utah: implications for the formation of non-depositional discontinuity surfaces
(Master thesis, 2005-11)The Sunnyside Member is part of the Blackhawk Formation and consists of shallow-marine and estuarine deposits reflecting high-frequency changes in sea level. Detailed mapping of the unit reveals an intra parasequence ... -
Downregulation of N-terminal acetylation triggers ABA-mediated drought responses in Arabidopsis
(Peer reviewed; Journal article, 2015-07-17)N-terminal acetylation (NTA) catalysed by N-terminal acetyltransferases (Nats) is among the most common protein modifications in eukaryotes, but its significance is still enigmatic. Here we characterize the plant NatA ... -
Downscaling an intense precipitation event in complex terrain: the importance of high grid resolution
(Peer reviewed; Journal article, 2017)Floods due to intense rainfall are a major hazard to both people and infrastructure in western Norway. Here steep orography enhances precipitation and the complex terrain channels the runoff into narrow valleys and small ... -
Downslope windstorm in Iceland –WRF/MM5 model comparison
(Peer reviewed; Journal article, 2011-01-05)A severe windstorm downstream of Mt. Öræfajökull in Southeast Iceland is simulated on a grid of 1 km horizontal resolution by using the PSU/NCAR MM5 model and the Advanced Research WRF model. Both models are run with a ... -

(Peer reviewed; Journal article, 2015-03-05)"Candidatus Methylacidiphilum kamchatkense" strain Kam1 is an aerobic methane-oxidizing thermoacidophilic bacterium belonging to the Verrucomicrobia phylum. It was recovered from an acidic geothermal site in Uzon Caldera, ... -
Draft Genome Sequence of Escherichia coli Strain Tj, Isolated from the Varzob River in Tajikistan
(Journal article, 2020)The 4.6-Mbp draft genome sequence of Escherichia coli strain Tj, isolated from the Varzob River in Tajikistan, is presented. This strain possesses four prophage elements related to Shigella phage SfV, E. coli O157:H7-specific ... -
Draft Genome Sequence of Thermus scotoductus Strain K1, Isolated from a Geothermal Spring in Karvachar, Nagorno Karabakh
(Peer reviewed; Journal article, 2015-11-12)The 2,379,636-bp draft genome sequence of Thermus scotoductus strain K1, isolated from geothermal spring outlet located in the Karvachar region in Nagorno Karabakh is presented. Strain K1 shares about 80% genome sequence ... -
Drag coefficient reduction at very high wind speeds
(Peer reviewed; Journal article, 2006-03-31)The correct representation of the 10-m drag coefficient for momentum (K10) at extreme wind speeds is very important for modeling the development of tropical depressions and may also be relevant to the understanding of other ... -
Drainage evolution in arid extensional settings and its controls on coral reef development: Sinai, Egypt
(Master thesis, 2019-06-26)The Sinai Peninsula is located in a hyper-arid climate environment, which affects drainage, development of coastal fan deltas and the growth of coral reef along the Gulf of Suez and Gulf of Aqaba. The recent extension of ... -
Drainage integration and sediment dispersal in active continental rifts: A numerical modelling study of the central Italian Apennines
(Journal article; Peer reviewed, 2018)Progressive integration of drainage networks during active crustal extension is observed in continental areas around the globe. This phenomenon is often explained in terms of headward erosion, controlled by the distance ... -

Drivers of Megabenthic Community Structure in One of the World’s Deepest Silled-Fjords, Sognefjord (Western Norway)
(Journal article; Peer reviewed, 2020-06-09)The Sognefjord is the longest (205 km) and deepest (1308 m) fjord in Norway, and the second-longest in the world. Coast-fjord exchange in Sognefjord is limited by a seaward sill at 170 m water depth, which causes a clear ... -
Drivers of spatial variability in spring bloom onset and magnitude along a latitudinal gradient in the Nordic Seas
(Master thesis, 2018-06-21)Spring phytoplankton blooms in the Nordic Seas contribute a large proportion of global primary production, and their timing and magnitude heavily impacts higher trophic levels. Two key drivers of bloom development, ... -
Drivers of the marine CO2 system in the High Arctic - from the deep basins to the shallow fjords
(Doctoral thesis, 2019-02-20)The High Arctic is largely undersampled in terms of marine CO2 system data due to the cold dark season and often an extensive sea ice cover. The current understanding of the Arctic carbon cycle is thus vulnerable to both ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach
(Peer reviewed; Journal article, 2019-03)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
Drivers of variation in the predator-prey interaction between cod and capelin in the Barents Sea
(Doctoral thesis, 2019-05-27)Cod (Gadus morhua) and capelin (Mallotus villosus) are commercially important species with key roles in the Barents Sea ecosystem. Cod is a major predator on capelin, and fluctuations in the capelin stock has influenced ... -
