Detecting anaerobic methane oxidation coupled to sulfate reduction in hydrothermal sediments
(Master thesis, 2022-03-07)The barite field is a low-temperature vent field, characterized by microbial activity and high fluid values of $NH_4$, $SO_4^{2-}$, and $CH_4$. Geochemical analysis indicates a hydrothermal system with a sedimentary input ... -
Detecting atmospheric rivers using persistent homology
(Master thesis, 2015-06-01)This master's thesis is a first investigation on the problem of seeing whether it is possible to detect atmospheric rivers using persistent homology. Two different computations are done and a basic analysis is made. In ... -
Detecting inosine in nanopore sequencing data with machine learning
(Master thesis, 2021-08-13)Detecting modifications in DNA has been a long-standing challenge in understanding the workings of the genome, particularly with regards to regulatory function. The currently most widely used sequencing technology, NGS, ... -
Detecting leakage of brine or CO2 through abandoned wells in a geological sequestration operation using pressure monitoring wells
(Peer reviewed; Journal article, 2011)For risk assessment, policy design and GHG emission accounting it is extremely important to know if any CO2 or brine has leaked from a geological sequestration (GS) operation. As such, it is important to understand if it ... -
Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
(Peer reviewed; Journal article, 2018-11-20)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -
Detecting Periodic Elements in Higher Topological Hochschild Homology
(Doctoral thesis, 2013-08-20) -
Detecting single amino acids and small peptides by combining isobaric tags and peptidomics
(Peer reviewed; Journal article, 2019)Single amino acids and small endogenous peptides play important roles in maintaining a properly functioning organism. These molecules are however currently only routinely identified in targeted approaches. In a small ... -
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
