Extra Dimensions at Particle Colliders
(Doctoral thesis, 2004-11-05) -
Extra-pair mating and evolution of cooperative neighbourhoods
(Peer reviewed; Journal article, 2014-07-02)A striking but unexplained pattern in biology is the promiscuous mating behaviour in socially monogamous species. Although females commonly solicit extra-pair copulations, the adaptive reason has remained elusive. We use ... -
Extra-pair paternity explains cooperation in a bird species
(Journal article; Peer reviewed, 2022)In many social animals, females mate with multiple males, but the adaptive value of female extra-pair mating is not fully understood. Here, we tested whether male pied flycatchers (Ficedula hypoleuca) engaging in extra-pair ... -
Extracting Rules from Neural Networks with Partial Interpretations
(Journal article; Peer reviewed, 2022)We investigate the problem of extracting rules, expressed in Horn logic, from neural network models. Our work is based on the exact learning model, in which a learner interacts with a teacher (the neural network model) via ... -
Extracting single target information from a simple echo sounder mounted on a drifting fish aggregating device (FAD)
(Master thesis, 2015-06-29)Fish aggregating devices (FADs) are widely used by purse seiners in the tropical tuna fisheries. Many species of fish including juvenile tuna often associate with these FADS. There are global decline in tuna catch largely ... -
Extracting statistical parameters of extreme precipitation from a NWP model
(Peer reviewed; Journal article, 2009-11-25)Precipitation simulations on an 8×8 km grid using the PSU/NCAR Mesoscale Model MM5 are used to estimate the M5 and Ci statistical parameters in order to support the M5 map used for flood estimates by Icelandic engineers. ... -
Extraction of form factors from a four-dimensional angular analysis of ¯B→D∗ℓ−¯νℓ
(Journal article; Peer reviewed, 2019-08-30)An angular analysis of the decay ¯B→D∗ℓ−¯νℓ, ℓ∈{e,μ}, is reported using the full e+e−collision data set collected by the BABAR experiment at the Υ(4S) resonance. One B meson from the Υ(4S)→B¯B decay is fully reconstructed ... -
The extreme Arctic warm anomaly in November 2020
(Journal article; Peer reviewed, 2022)In November 2020, the eastern Arctic experienced an extensive extreme warm anomaly (i.e., the second strongest case since 1979), which was followed by extreme cold conditions over East Asia in early winter. The observed ... -
Extreme Event Statistics in Dst, SYM-H, and SMR Geomagnetic Indices
(Journal article; Peer reviewed, 2023)Extreme space weather events are rare, and quantifying their likelihood is challenging, often relying on geomagnetic indices obtained from ground-based magnetometer observations that span multiple solar cycles. The Dst ... -
Extreme precipitation in Central Norway. A case and climate study
(Master thesis, 2010-06-01)An extreme precipitation event occurred over Central Norway at the end of January to the beginning of February 2006. The heavy precipitation in addition to high temperatures lead to snow melt and increased run-off, which ... -
Extreme Precipitation in Nepal. Trends and Key Processes
(Doctoral thesis, 2018-03-21)Nepal is located at the rim of the Himalayas and houses the highest mountains of the world. Owing to the complex topography and a seasonal monsoon climate, Nepal experiences precipitation events of considerable intensity. ... -
Extreme wave runup on a steep coastal profile
(Journal article; Peer reviewed, 2020)It is shown that very steep coastal profiles can give rise to unexpectedly large wave events at the coast. We combine insight from exact solutions of a simplified mathematical model with photographs from observations at ... -
Extreme winds in the Nordic Seas : polar lows and Arctic fronts in a changing climate
(Doctoral thesis, 2007-03-30) -
Extremes and Trends in Wave Climate. A regional and global study
(Doctoral thesis, 2015-01-16)Wind generated surface waves represent a critical factor for offshore constructions and coastal development, and are highly relevant in scientific questions related to climate and weather. The sea state can be described ... -
f0(980) resonance production in pp collisions with the ALICE detector at the LHC
(Peer reviewed; Journal article, 2019)We report on a preliminary study of the production of f0(980) → π+π− at mid-rapidity (|y| < 0.5) performed with the ALICE detector at the LHC in minimum bias pp collisions at the centre-of-mass energy √ s = 5.02 TeV. The ... -
Fabrication of large free-standing nanostructured zone plates for focusing a Bose-Einstein condensate
(Master thesis, 2017-09-20)Matter wave optics is a fascinating area of physics touching many scientific disciplines ranging from microscopy to high precision gravity measurements. One of the major recent breakthroughs was the realization in 1995 of ... -
Fabrication of nanostructured free-standing Fresnel zone plate for neutral matter-waves microscopy
(Master thesis, 2022-06-01) -
Facies Analysis and Sandbody Geometry of the Paleogene Battfjellet Formation, Central Western Nordenskiöld Land, Spitsbergen
(Master thesis, 2010)New sedimentological data from the central part of Nordenskiöld Land, Spitsbergen, contributes to the understanding of the depositional processes and sandbody geometry of the Battfjellet Formation (Eocene). A detailed ... -
