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 ... -
The COTUR project: remote sensing of offshore turbulence for wind energy application
(Journal article; Peer reviewed, 2021)The paper presents the measurement strategy and data set collected during the COTUR (COherence of TURbulence with lidars) campaign. This field experiment took place from February 2019 to April 2020 on the southwestern coast ... -

Counting Instances of Software Components
(Proceedings of LRPP'04: Workshop on Logics for Resources, Processes, and Programs, Turku, Finland, July 13, 2004, Conference lecture, 2004-07-13)Component software is software that has been assembled from various pieces of standardized, reusable computer programs, so-called components. Executing component software creates instances of these components. For several ... -
Counting research ⇒ directing research : the hazard of using simple metrics to evaluate scientific contributions : an EU experience
(Journal article; Peer reviewed, 2017)In many EU countries there is a requirement to count research, i.e., to measure and prove its value. These numbers, often produced automatically based on the impact of journals, are used to rank universities, to determine ... -
Coupled Al-Si geochemistry in an ocean general circulation model: A tool for the validation of oceanic dust deposition fields?
(Peer reviewed; Journal article, 2003-03-19)We introduced the marine cycle of Al into a geochemical ocean general circulation model in order to assess the potential of modeled surface ocean dissolved Al as a tracer for dust input to the world ocean. The geochemical ... -
Coupled atmosphere-ice-ocean dynamics in Dansgaard-Oeschger events
(Peer reviewed; Journal article, 2018-11-10)The Dansgaard-Oeschger events of the last ice age are among the best studied abrupt climate changes, yet a comprehensive explanation is still lacking. They are most pronounced in the North Atlantic, where they manifest as ... -
Coupled atmosphere–ocean observations of a cold-air outbreak and its impact on the Iceland Sea
(Journal article; Peer reviewed, 2023)Marine cold-air outbreaks (CAOs) are vigorous equatorward excursions of cold air over the ocean, responsible for the majority of wintertime oceanic heat loss from the subpolar seas of the North Atlantic. However, the impact ... -
Coupled effects of wave and depth-dependent current interaction on loads on a bottom-fixed vertical slender cylinder
(Journal article; Peer reviewed, 2023)The coupled effects of waves and a subsurface current on the hydrodynamic loads on offshore slender structures in coastal water regions have been examined in this paper, especially the coupling of the weak nonlinearity of ... -
Coupled Mg/Ca and Clumped Isotope Measurements Indicate Lack of Substantial Mixed Layer Cooling in the Western Pacific Warm Pool During the Last ∼5 Million Years
(Journal article; Peer reviewed, 2021)The Indo-Pacific Warm Pool (IPWP) plays a crucial role in influencing climate dynamics both in the tropics and globally. Yet, there is an ongoing controversy concerning the evolution of surface temperatures in the IPWP ... -
Coupled Southern Ocean cooling and Antarctic ice sheet expansion during the middle Miocene
(Journal article; Peer reviewed, 2020)The middle Miocene climate transition (~14 million years ago) was characterized by a dramatic increase in the volume of the Antarctic ice sheet. The driving mechanism of this transition remains under discussion, with ... -
Coupled stalagmite - Alluvial fan response to the 8.2ka event and early Holocene palaeoclimate change in Greece
(Peer reviewed; Journal article, 2019)We explore the expression of early Holocene climatic change in the terrestrial Mediterranean of southern Greece. A regional palaeoclimate record from stable isotope and trace element geochemical proxies in an early Holocene ... -
Coupled stratosphere-troposphere-Atlantic multidecadal oscillation and its importance for near-future climate projection
(Journal article; Peer reviewed, 2022)Northern Hemisphere (NH) climate has experienced various coherent wintertime multidecadal climate trends in stratosphere, troposphere, ocean, and cryosphere. However, the overall mechanistic framework linking these trends ... -
Coupled surface process and tectonic modelling of extension-inversion tectonics in the Pyrenees

Coupling Crustal-Scale Rift Architecture With Passive Margin Salt Tectonics: A Geodynamic Modeling Approach
(Journal article; Peer reviewed, 2022)Continental rifted margins are often associated with widespread, thick evaporite (i.e., salt) deposits and pronounced salt tectonics. The majority of salt basins formed during the latest stages of rifting, prior to continental ... -
Covering Radius of Generalized Zetterberg Type Codes Over Finite Fields of Odd Characteristic
(Journal article; Peer reviewed, 2023)Let Fq0 be a finite field of odd characteristic. For an integer s≥1 , let Cs(q0) be the generalized Zetterberg code of length qs0+1 over Fq0 . If s is even, then we prove that the covering radius of Cs(q0) is 3. Put q=qs0 ... -
Covering tour problem with varying coverage: Application to marine environmental monitoring
(Journal article; Peer reviewed, 2023)In this paper, we present a novel variant of the Covering Tour Problem (CTP), called the Covering Tour Problem with Varying Coverage (CTP-VC). We consider a simple graph 𝐺 = (𝑉 ,𝐸), with a measure of importance assigned ... -
Covering Vectors by Spaces in Perturbed Graphic Matroids and Their Duals
(Peer reviewed; Journal article, 2019)Perturbed graphic matroids are binary matroids that can be obtained from a graphic matroid by adding a noise of small rank. More precisely, an r-rank perturbed graphic matroid M is a binary matroid that can be represented ...
