Grain Deformation Processes in Porous Quartz Sandstones – Insight from the Clusters of Cataclastic Deformation Bands
(Peer reviewed; Journal article, 2017)Porous sandstones represent classical reservoirs for water or hydrocarbons. Deformation in such granular material is due to tectonic events and occurs through the process of cataclasis, implying the crushing of the grains ... -
Grain-Size Analysis of the Late Pleistocene Sediments in the Corinth Rift: Insights into Strait Influenced Hydrodynamics and Provenance of an Active Rift Basin
(Journal article; Peer reviewed, 2022)Grain-size analysis of the sediments in borehole M0079A, which is located in the Corinth Rift, was used to explore hydrodynamic conditions and provenance in the Late Pleistcene Corinth Rift. Grain-size populations that ... -
GRANADA consensus on analytical approaches to assess associations with accelerometer-determined physical behaviours (physical activity, sedentary behaviour and sleep) in epidemiological studies
(Journal article; Peer reviewed, 2021)The inter-relationship between physical activity, sedentary behaviour and sleep (collectively defined as physical behaviours) is of interest to researchers from different fields. Each of these physical behaviours has been ... -
Graph Algebras and Derived Graph Operations
(Journal article, 2023)We revise our former definition of graph operations and correspondingly adapt the construction of graph term algebras. As a first contribution to a prospective research field, Universal Graph Algebra, we generalize some ... -
Graph Constructions for the Contact Process with a Prescribed Critical Rate
(Journal article; Peer reviewed, 2021)We construct graphs (trees of bounded degree) on which the contact process has critical rate (which will be the same for both global and local survival) equal to any prescribed value between zero and λc(Z), the critical ... -
A Graph Feature Auto-Encoder for the Prediction of Unobserved Node Features on Biological Networks
(Journal article; Peer reviewed, 2021)Background Molecular interaction networks summarize complex biological processes as graphs, whose structure is informative of biological function at multiple scales. Simultaneously, omics technologies measure the variation ... -
Graph modification problems: Beyond the known boundaries
(Doctoral thesis, 2017-11-17) -
Graphene and graphene oxide on Ir(111) are transparent to wetting but not to icing
(Journal article; Peer reviewed, 2021)Anti-icing coatings reduce the freezing onset temperature for water by changing the chemical and physical environment at the water-substrate interface to prevent ice nucleation and growth. Graphene oxide has several ... -
Graphical Computing Solution for Industrial Plant Engineering
(Master thesis, 2017-06-21)When preparing an engineering operation on an industrial plant, reliable and updated models of the plant must be available for correct decisions and planning. However, especially in the case of offshore oil and gas ... -
Gravitino dark matter and the flavour structure of R-violating operators
(Peer reviewed; Journal article, 2009-06-15)We study gravitino dark matter and slow gravitino decays within the framework of R-violating supersymmetry, with particular emphasis on the flavour dependence of the branching ratios and the allowed R-violating couplings. ... -
Gravitino Dark Matter with Entropy Production constrained by Big Bang Nucleosynthesis
(Master thesis, 2016-12-16)We are looking at a gravitino dark matter scenario with a general neutralino next-to-lightest supersymmetric particle. We are considering the primary decay channels of the neutralino, and we define the supersymmetric ... -

Gravity modeling: Calculations based on porosity-density context
(Master thesis, 2010-06-17)A normal way to model the gravity from a layered model is to determine the densities from the velocities, and then adjusting the densities within acceptable ranges to get a satisfactory fit with the observed gravity. In ... -
Gray whale habitat use and reproductive success during seismic surveys near their feeding grounds: comparing state-dependent life history models and field data
(Journal article; Peer reviewed, 2022)We used a stochastic dynamic programming (SDP) model to quantify the consequences of disturbance on pregnant western gray whales during one foraging season. The SDP model has a firm basis in bioenergetics, but detailed ... -
Grazing on Marine Viruses and Its Biogeochemical Implications
(Journal article; Peer reviewed, 2023)Viruses are the most abundant biological entities in the ocean and show great diversity in terms of size, host specificity, and infection cycle. Lytic viruses induce host cell lysis to release their progeny and thereby ... -
The greater Agulhas Current system: an integrated study of its mesoscale variability
(Journal of Operational Oceanography, Journal article, 2008-02)For the purpose of developing an operational oceanography system for the greater Agulhas Current regime, a high resolution Hybrid Coordinate Ocean Model (HYCOM) has been set in a nested configuration. The intense and complex ... -
Greenland climate simulations show high Eemian surface melt which could explain reduced total air content in ice cores
(Journal article; Peer reviewed, 2021)This study presents simulations of Greenland surface melt for the Eemian interglacial period (∼130 000 to 115 000 years ago) derived from regional climate simulations with a coupled surface energy balance model. Surface ... -
Greenland surface air temperature changes from 1981 to 2019 and implications for ice-sheet melt and mass-balance change
(Journal article; Peer reviewed, 2020)We provide an updated analysis of instrumental Greenland monthly temperature data to 2019, focusing mainly on coastal stations but also analysing ice‐sheet records from Swiss Camp and Summit. Significant summer (winter) ... -
Greenland-Scotland overflow studied by hydro-chemical multivariate analysis
(Peer reviewed; Journal article, 2003-01)Hydrographic, nutrient and halocarbon tracer data collected in July-August 1994 in the Norwegian Sea, the Faroe Bank Channel (FBC), the Iceland and Irminger Basins and the Iceland Sea are resented. Special attention was ... -
Grein. A New Non-Linear Cryptoprimitive
(Master thesis, 2013-12-10)In this thesis, we will study a new stream cipher, Grein, and a new cryptoprimitive used in this cipher. The second chapter gives a brief introduction to cryptography in general. The third chapter looks at stream ciphers ...
