Realistic mask generation for matter-wave lithography via machine learning
(Journal article; Peer reviewed, 2023)Fast production of large-area patterns is crucial for the established semiconductor industry and enables industrial-scale production of next-generation quantum devices. Metastable atom lithography with binary holography ... -
A reappraisal of the H–κ stacking technique: implications for global crustal structure
(Journal article; Peer reviewed, 2019)H–κ stacking is used routinely to infer crustal thickness and bulk-crustal VP/VS ratio from teleseismic receiver functions. The method assumes that the largest amplitude P-to-S conversions beneath the seismograph station ... -
Rearing conditions and automated feed distribution systems for zebrafish (Danio rerio)
(Journal article; Peer reviewed, 2022)Zebrafish (Danio rerio) is a well-established animal model, used in a number of research areas. In the last decade, it has also emerged as a tool to evaluate the effects of diets and dietary components and to test novel ... -
Recalibration of the MEPED Proton Detectors Onboard NOAA POES Satellites
(Master thesis, 2013-07-04)In this thesis we have calibrated energetic proton data from the solid state detectors of the MEPED instrument onboard the satellites NOAA 15, 16, 17, 18, and MetOp 02. All these satellites are part of the NOAA/POES program, ... -
Recent and future changes of the Arctic sea-ice cover
(Peer reviewed; Journal article, 2008)The present and future state of the Arctic sea ice cover is explored using new observations and a coupled one dimensional air–sea–ice model. Updated satellite observations of Fram Strait ice-area export show an increase ... -
Recent applications and potential of near-term (interannual to decadal) climate predictions
(Journal article; Peer reviewed, 2023)Following efforts from leading centres for climate forecasting, sustained routine operational near-term climate predictions (NTCP) are now produced that bridge the gap between seasonal forecasts and climate change projections ... -
Recent drought and precipitation tendencies in Ethiopia
(Peer reviewed; Journal article, 2013-05)In 2011, drought in the Horn of Africa again made news headlines. This study aims to quantify the meteorological component of this and other drought episodes in Ethiopia since 1971. A monthly precipitation data set for 14 ... -
Recent ecosystem dynamics in nine North African lakes in the CASSARINA Project
(Peer reviewed; Journal article, 2001)An integrated multi-disciplinary study of nine North African lakes (CASSARINA) aims to establish ecological baselines and to explore responses to 20th century human impacts on their ecosystems. Water chemistry measurements ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – an introduction
(Peer reviewed; Journal article, 2004)This paper outlines an interdisciplinary project on recent environmental change and atmospheric contamination on the high Arctic archipelago of Svalbard (76º30'N – 80º30'N). It describes the rationale and aims of the project ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – modern limnology, vegetation, and pollen deposition
(Peer reviewed; Journal article, 2004)Twenty-four lakes on Svalbard were sampled for palaeolimnological studies and are described in terms of their geographical location, catchment characteristics, water chemistry, and flora. No sediment could be retrieved ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – synthesis and general conclusions
(Peer reviewed; Journal article, 2004)The major patterns of biostratigraphical and geochemical change detected in a multidisciplinary study on recent environmental change and atmospheric contamination on Svalbard are summarised and synthesized. The patterns ... -
Recent environmental change and human impact on Svalbard: the lake-sediment geochemical record
(Peer reviewed; Journal article, 2004)As part of a broader investigation into recent environmental change on Svalbard, the inorganic geochemical record of six lake-sediment cores was analysed. The major temporal trends in sediment elemental composition are ... -
Recent Evolution of Glaciers in the Manaslu Region of Nepal From Satellite Imagery and UAV Data (1970–2019)
(Journal article; Peer reviewed, 2022)Glacierized mountain ranges such as the Himalaya comprise a variety of glacier types, including clean and debris-covered glaciers. Monitoring their behaviour over time requires an assessment of changes in area and elevation ... -
Recent Hadley circulation strengthening: a trend or multidecadal variability?
(Journal article; Peer reviewed, 2022)This study explores the possible drivers of the recent Hadley circulation strengthening in the modern reanalyses. Predominantly, two recent generations of reanalyses provided by the European Centre for Medium-Range Weather ... -
Recent increases in species richness and shifts in altitudinal distributions of Norwegian mountain plants
(Peer reviewed; Journal article, 2003)Opportunities for observing long-term changes in natural biota are rare. Observations on the distribution and frequency of vascular plants were performed on 23 mountains situated along a west–east gradient in Jotunhei men, ... -
Recent Intensified Influence of the Winter North Pacific Sea Surface Temperature on the Mei-Yu Withdrawal Date
(Journal article; Peer reviewed, 2021)The mei-yu withdrawal date (MWD) is a crucial indicator of flood/drought conditions over East Asia. It is characterized by a strong interannual variability, but its underlying mechanism remains unknown. We investigated the ... -
Recent trends in abundance and fishing pressure of agency-assessed small pelagic fish stocks
(Journal article; Peer reviewed, 2022)Small pelagic fishes are used for human consumption, fishmeal and fish oil. They constitute 25% of global fish catch and have been of considerable conservation concern because of their intermediate position in aquatic food ... -
Recent weakening in the winter ENSO teleconnection over the North Atlantic‑European region
