Nest predation, reproductive investment, and environmental variability in Atlantic puffin (Fratercula arctica)
(Master thesis, 2021-06-30)For many species of birds, nest predation is one of the leading causes of reproductive failure. This has been especially apparent in island nesting seabirds, which have experienced rapid declines due to the introduction ... -
A nested multi-scale system implemented in the large-eddy simulation model PALM model system 6.0
(Journal article; Peer reviewed, 2021)Large-eddy simulation (LES) provides a physically sound approach to study complex turbulent processes within the atmospheric boundary layer including urban boundary layer flows. However, such flow problems often involve a ... -
Nesting synchrony and clutch size in migratory birds: Capital versus income breeding determines responses to variable spring onset
(Journal article; Peer reviewed, 2021)Synchronous reproduction of birds has often been explained by benefits from nesting together, but this concept fails to explain observed intraspecific variation and climate-mediated changes of breeding synchrony. Here, we ... -
Net cleaning impacts Atlantic salmon gill health through microbiome dysbiosis
(Journal article, 2023)Net biofouling has a significant impact for the global salmon industry in the seawater grow-out stage in terms of its management. Current mitigation strategies occur primarily through the regular removal of biofouling using ... -
Net-baryon fluctuations measured with ALICE at the CERN LHC
(Peer reviewed; Journal article, 2017-11)First experimental results are presented on event-by-event net-proton fluctuation measurements in Pb- Pb collisions at \(\sqrt{s_{NN}}\) = 2.76 TeV, recorded by the ALICE detector at the CERN LHC. The ALICE detector is ... -
Nettle as a distinct Bronze Age textile plant
(Peer reviewed; Journal article, 2012-09-28)It is generally assumed that the production of plant fibre textiles in ancient Europe, especially woven textiles for clothing, was closely linked to the development of agriculture through the use of cultivated textile ... -
Network analysis of Arabidopsis mitochondrial dynamics reveals a resolved tradeoff between physical distribution and social connectivity
(Journal article; Peer reviewed, 2021)Mitochondria in plant cells exist largely as individual organelles which move, colocalize, and interact, but the cellular priorities addressed by these dynamics remain incompletely understood. Here, we elucidate these ... -
Network analysis of geomagnetic substorms using the SuperMAG database of ground-based magnetometer stations
(Peer reviewed; Journal article, 2015-09-26)The overall morphology and dynamics of magnetospheric substorms is well established in terms of the observed qualitative auroral features seen in ground-based magnetometers. This paper focuses on the quantitative ... -
Network coding in Bluetooth networks
(Master thesis, 2009-10-01)This thesis discusses the possibility to apply network coding to a Bluetooth piconet. A protocol is proposed. This protocol is based on using deterministic linear network coding. The proposed alphabet size is binary, and ... -
Network community structure of substorms using SuperMAG magnetometers
(Journal article; Peer reviewed, 2021)Geomagnetic substorms are a global magnetospheric reconfiguration, during which energy is abruptly transported to the ionosphere. Central to this are the auroral electrojets, large-scale ionospheric currents that are part ... -
Neural activation in photosensitive brain regions of Atlantic salmon (Salmo salar) after light stimulation
(Journal article; Peer reviewed, 2021)Photoreceptive inputs to the teleost brain are perceived as image of the visual world and as photo-modulation of neuroendocrine and neuronal signals. The retina and pineal organ are major receptive organs with projections ... -
Neural network approach for correction of multiple scattering errors in the LISST-VSF instrument
(Journal article; Peer reviewed, 2023)The LISST-VSF is a commercially developed instrument used to measure the volume scattering function (VSF) and attenuation coefficient in natural waters, which are important for remote sensing, environmental monitoring and ... -
A Neural Network Method for Retrieving Sea Surface Wind Speed for C-Band SAR
(Journal article; Peer reviewed, 2022-05-08)Based on the Ocean Projection and Extension neural Network (OPEN) method, a novel approach is proposed to retrieve sea surface wind speed for C-band synthetic aperture radar (SAR). In order to prove the methodology with a ... -
A Neural Network-Based Analysis of the Seasonal Variability of Surface Total Alkalinity on the East China Sea Shelf
(Journal article; Peer reviewed, 2020)Total alkalinity (AT) is an important variable in the regulation of the seawater carbonate chemistry system, determining the capacity to buffer changes in pH. In the coastal oceans, carbonate system dynamics are controlled ... -
Neural Networks for Lossy Weakly-Private Information Retrieval
(Master thesis, 2021-06-01)The availability of information through public accessible databases has never beengreater, but do raise privacy concerns. Private information retrieval schemes guar-antees full privacy regarding the servers ability to infer ... -
Neural Substrates of Psychotic Depression: Findings From the Global ECT-MRI Research Collaboration
(Journal article; Peer reviewed, 2021)Psychotic major depression (PMD) is hypothesized to be a distinct clinical entity from nonpsychotic major depression (NPMD). However, neurobiological evidence supporting this notion is scarce. The aim of this study is to ... -
Neuroendocrine factors involved in appetite control and feed intake in Atlantic salmon (Salmo salar) reared in Recirculating Aquaculture Systems (RAS).
(Master thesis, 2018-11-15)The control of appetite in vertebrates is a complex process that depends on a range of signals from peripheral tissues and neuro- and endocrine signals originating in the brain. The hypothalamus is believed to be the main ... -
Neurohypophysial and paracrine vasopressinergic signaling regulates aquaporin trafficking to hydrate marine teleost oocytes
(Journal article; Peer reviewed, 2023)The dual aquaporin (Aqp1ab1/Aqp1ab2)-mediated hydration of marine teleost eggs, which occurs during oocyte meiosis resumption (maturation), is considered a key adaptation underpinning their evolutionary success in the ... -
Neuronal cell lipidomics and role of cholesterol in α-synuclein binding and aggregation
(Doctoral thesis, 2019-03-22)α-Synuclein is an intrinsically disordered protein whose fold and multimeric state is strongly affected by its environment. The monomers of α-synuclein are enriched in the presynaptic terminals of dopaminergic ... -
