Coralline algal Barium as indicator for 20th century northwestern North Atlantic surface ocean freshwater variability
(Peer reviewed; Journal article, 2013)During the past decades climate and freshwater dynamics in the northwestern North Atlantic have undergone major changes. Large-scale freshening episodes, related to polar freshwater pulses, have had a strong influence on ... -
Core-scale sensitivity study of CO2 foam injection strategies for mobility control, enhanced oil recovery, and CO2 storage
(Journal article; Peer reviewed, 2020)This paper presents experimental and numerical sensitivity studies to assist injection strategy design for an ongoing CO2 foam field pilot. The aim is to increase the success of in-situ CO2 foam generation and propagation ... -
Coring of unconsolidated permafrost deposits: methodological successes and challenges
(Chapter; Peer reviewed, 2015)This technical note presents three scales of drilling infrastructure for comparison. These three methods include: (1) a small hand-drill designed for retrieving cores down to ca. 5 m depth, (2) the medium-scale UNIS ... -
Coronal Cavities in CoMP Observations
(Journal article; Peer reviewed, 2022)Quiescent coronal cavities can provide insight into solar magnetic fields. They are observed in the coronal emission lines in both polarized and unpolarized light. In the total linear polarization fraction (L/I), they often ... -

Correcting the impact of the isotope composition on the mixing ratio dependency of water vapour isotope measurements with cavity ring-down spectrometers
(Journal article; Peer reviewed, 2020)Recent advances in laser spectroscopy enable high-frequency in situ measurements of the isotope composition of water vapour. At low water vapour mixing ratios, however, the measured stable water isotope composition can be ... -

Correlated event-by-event fluctuations of flow harmonics in Pb-Pb collisions at \(\sqrt{s_{\rm NN}}=2.76\) TeV
(Peer reviewed; Journal article, 2016-10)We report the measurements of correlations between event-by-event fluctuations of amplitudes of anisotropic flow harmonics in nucleus–nucleus collisions, obtained for the first time using a new analysis method based on ... -
Correlated ionization processes in atoms and molecules
(Doctoral thesis, 2013-09-27)This thesis is composed of five scientific papers written between 2009 and 2013. The focus of this work is on various photo-ionization processes in small atoms and molecules. The strong field phenomenon called “atomic ... -
Correlated long-range mixed-harmonic fluctuations measured in pp, p+Pb and low-multiplicity Pb+Pb collisions with the ATLAS detector
(Peer reviewed; Journal article, 2019)Correlations of two flow harmonics vn and vm via three- and four-particle cumulants are measured in 13 TeV pp, 5.02 TeV p+Pb, and 2.76 TeV peripheral Pb+Pb collisions with the ATLAS detector at the LHC. The goal is to ... -
A correlation giving improved description of the capacity and efficiency of vane-type gas-liquid separators
(Peer reviewed; Journal article, 2019)Vane‐type demisters are attractive droplet separators because they combine robustness and sufficient separation efficiency with a low‐pressure drop, a high capacity and some fouling resistance. Experience shows that their ... -
Correlations among elliptic flow parameter, impact parameter, and multiplicity
(Peer reviewed; Journal article, 2010-09-01)The elliptic flow parameter, v2, in the Fourier expansion of the event-by-event charged-particle multiplicity azimuthal distribution in the momentum space is studied by taking into account the multiplicity fluctuations. ... -
Correlations between the effective permeability and seismic anisotropy of fractured reservoirs
(Doctoral thesis, 2011-08-23)The successful exploitation of many hydrocarbon reservoirs may depend on proper characterization of fractured or composite porous media. However, due to anisotropy and heterogeneity, the characterization of such kind of ... -
Correlative evidence for competition between fucus serratus and the introduced chlorophyte codium fragile subsp. fragile on the southwest coast of Norway
(Peer reviewed; Journal article, 2014)The distribution of Codium fragile subsp. fragile and the native canopy-forming alga Fucusserratus was recorded at 51 sites in a 20 km long, sheltered region on the southwest coast of Norway. The purpose of the study was ... -
Cosmic Ray Signatures from Decaying Gravitino Dark Matter
(Journal article; Peer reviewed, 2010)We study the charged cosmic rays arising from the slow decay of gravitino dark matter within supersymmetric scenarios with trilinear R-parity violation. It is shown that operators of the LLE type can very well account for ... -
Cost efficient environmental survey paths for detecting continuous tracer discharges
(Peer reviewed; Journal article, 2017-07)Designing monitoring programs for detecting potential tracer discharges from unknown locations is challenging. The high variability of the environment may camouflage the anticipated anisotropic signal from a discharge, and ... -
Cost-sensitive ensemble learning: a unifying framework
(Journal article; Peer reviewed, 2022)Over the years, a plethora of cost-sensitive methods have been proposed for learning on data when different types of misclassification errors incur different costs. Our contribution is a unifying framework that provides a ...
