Detection and quantification of CO2 seepage in seawater using the stoichiometric Cseep method: Results from a recent subsea CO2 release experiment in the North Sea
(Journal article; Peer reviewed, 2021)Carbon Capture and Storage (CCS) is a potential significant mitigation strategy to combat climate change and ocean acidification. The technology is well understood but its current implementation must be scaled up nearly ... -
Detection and Timing of Gamma-Ray Pulsations from the 707 Hz Pulsar J0952−0607
(Journal article; Peer reviewed, 2019)The Low-Frequency Array radio telescope discovered the 707 Hz binary millisecond pulsar (MSP) J0952−0607 in a targeted radio pulsation search of an unidentified Fermi gamma-ray source. This source shows a weak energy flux ... -
Detection of CO2 in N2 and H2O using photoacoustics
(Master thesis, 2013-06-03)Photoacoustic spectroscopy is a technique where absorbed modulated light is released as heat, causing thermal expansion which can be detected using an acoustic transducer. It can be used to determine the absorption spectra ... -
Detection of ice core particles via deep neural networks
(Journal article; Peer reviewed, 2023)Insoluble particles in ice cores record signatures of past climate parameters like vegetation dynamics, volcanic activity, and aridity. For some of them, the analytical detection relies on intensive bench microscopy ... -
Detection of low energy antiproton annihilations in a segmented silicon detector
(Peer reviewed; Journal article, 2014-06)The goal of the AEḡIS experiment at the Antiproton Decelerator (AD) at CERN, is to measure directly the Earth’s gravitational acceleration on antimatter by measuring the free fall of a pulsed, cold antihydrogen beam. The ... -
Detection of misfolded protein aggregates from a clinical perspective
(Peer reviewed; Journal article, 2016)Neurodegenerative Protein Misfolding Diseases (PMDs), such as Alzheimer’s (AD), Parkinson’s (PD) and prion diseases, are generally difficult to diagnose before irreversible damage to the central nervous system damage has ... -
Detection of terrestrial gamma-ray flashes with the AGILE/MCAL
(Peer reviewed; Journal article, 2019)AGILE is one of the satellites currently detecting terrestrial gamma-ray flashes (TGFs). In particular, the AGILE MiniCALorimeter detected more than 2000 events in 8 years activity, by exploiting a unique sub-millisecond ... -
Detection of the myxosporean parasite Parvicapsula pseudobranchicola in Atlantic salmon (Salmo salar L.) using in situ hybridization (ISH)
(Peer reviewed; Journal article, 2015-02-15)Background: Parvicapsula pseudobranchicola is a marine myxosporean parasite infecting farmed Atlantic salmon (Salmo salar). A major site for the parasite is the pseudobranch, which may be destroyed in heavily infected fish. ... -
Determination of jet calibration and energy resolution in proton–proton collisions at √s=8TeV using the ATLAS detector
(Journal article; Peer reviewed, 2020)The jet energy scale, jet energy resolution, and their systematic uncertainties are measured for jets reconstructed with the ATLAS detector in 2012 using proton–proton data produced at a centre-of-mass energy of 8 TeV with ... -
Determination of the event collision time with the ALICE detector at the LHC
(Peer reviewed; Journal article, 2017-02)Particle identification is an important feature of the ALICE detector at the LHC. In particular, for particle identification via the time-of-flight technique, the precise determination of the event collision time represents ... -
Determination of the minimum ignition energy (MIE) of premixed propane/air
(Master thesis, 2009-06-12)This Master thesis describes an experimental study aimed at determining the minimum ignition energy (MIE) of premixed propane/air mixtures. Two fundamentally different circuits have been employed for creating the sparks ... -
Determination of the parton distribution functions of the proton from ATLAS measurements of differential W± and Z boson production in association with jets
(Journal article; Peer reviewed, 2021)This article presents a new set of proton parton distribution functions, ATLASepWZVjet20, produced in an analysis at next-to-next-to-leading order in QCD. The new data sets considered are the measurements of W+ and W− boson ... -
The Determination of the Snow Optical Grain Diameter and Snowmelt Area on the Greenland Ice Sheet Using Spaceborne Optical Observations
(Journal article; Peer reviewed, 2022)The optical diameter of the surface snow grains impacts the amount of energy absorbed by the surface and therefore the onset and magnitude of surface melt. Snow grains respond to surface heating through grain metamorphism ... -
Determining individual variation in growth and its implication for life-history and population processes using the Empirical Bayes method
(Peer reviewed; Journal article, 2014-09-11)The differences in demographic and life-history processes between organisms living in the same population have important consequences for ecological and evolutionary dynamics. Modern statistical and computational methods ... -
Determining Latitudinal Extent of Energetic Electron Precipitation Using MEPED On-Board NOAA/POES
(Journal article; Peer reviewed, 2022)Energetic Electron Precipitation (EEP) from the plasma sheet and the radiation belts ionizes the polar lower thermosphere and mesosphere. EEP increases the production of NOx and HOx, which will catalytically destroy ozone, ... -
Determining the Cell Size of Yeast Using Diffusion-Weighted NMR
(Master thesis, 2019-11-16)Abstract This study uses diffusion weighted NMR to determine yeast cell size at different times after those cells were suspended in water. Both the water diffusion and the metabolite diffusion where used in those measurements. ... -
Determining the fibrillar orientation of bast fibres with polarized light microscopy: the modified Herzog test (red plate test) explained
(Peer reviewed; Journal article, 2013)The identification of bast fibre samples, in particular, bast fibres used in textiles, is an important issue in archaeology, criminology and other scientific fields. One of the characteristic features of bast fibres is ... -
Detours in Directed Graphs
(Journal article; Peer reviewed, 2022)We study two "above guarantee" versions of the classical Longest Path problem on undirected and directed graphs and obtain the following results. In the first variant of Longest Path that we study, called Longest Detour, ... -
