A Binomial Stochastic Framework for Efficiently Modeling Discrete Statistics of Convective Populations
; (Journal of Advances in Modeling Earth Systems, 2021-03-23)
Understanding the coupling between convective clouds and the general circulation, as well as addressing the gray zone problem in convective parameterization, requires insight into the genesis and maintenance of spatial ... -
A Burmese amber fossil of Radula (Porellales, Jungermanniopsida) provides insights into the Cretaceous evolution of epiphytic lineages of leafy liverworts
(Fossil Record, 2017)DNA-based divergence time estimates suggested major changes in the composition of epiphyte lineages of liverworts during the Cretaceous; however, evidence from the fossil record is scarce. We present the first Cretaceous ... -
A chronological and palaeoenvironmental re‐evaluation of two loess‐palaeosol records in the northern Harz foreland, Germany, based on innovative modelling tools
; ; ; ; (Boreas, 2021-02-04)
The continuing development of analytical methods for investigating sedimentary records calls for iterative re‐examination of existing data sets obtained on loess‐palaeosol sequences (LPS) as archives of palaeoenvironmental ... -
A cold pool perturbation scheme to improve convective initiation in convection‐permitting models
; (Quarterly Journal of the Royal Meteorological Society, 2021-05-04)
Cold pools originate from evaporation in precipitating downdraughts and spread as density currents at the surface. Vertical motion at the leading edge of the cold pool is an important trigger for new convective cells in ... -
A Combined Neural Network‐ and Physics‐Based Approach for Modeling Plasmasphere Dynamics
; ; (Journal of Geophysical Research: Space Physics, 2021-03-16)
In recent years, feedforward neural networks (NNs) have been successfully applied to reconstruct global plasmasphere dynamics in the equatorial plane. These neural network‐based models capture the large‐scale dynamics of ... -
A combined structural interpretation based on seismic data and 3-D gravity modeling in the northern Puna/Eastern Cordillera, Argentina
(Selbstverlag Fachbereich Geowissenschaften Freie Universität Berlin, 1998)Die Andenkordillere entstand entlang des westlichen Randes von Südamerika aufgrund der Subduktion der ozeanischen Nazca-Platte unter die kontinentale Südamerikaplatte seit dem Jura. Als solche werden die Anden als ein ... -
A comparative study of the diagenesis in diapir-influenced reef atolls and a fault block reef platform in the Late Albian of the Vasco-Cantabrian Basin
(Reef diagenesisReef diagenesis, 1986)

A comparison of Bayesian hierarchical space-time models for earthquake data
(2004)Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere-Jones (1995). This gives a fine resolution both in space and time making it possible to represent each ... -
A concept for a regional coastal zone mission
(Univ. Berlin, 2002) -
A contribution to characterizing and calibrating the pointing control system of the SOFIA telescope
(Univ. Stuttgart, 2009)SOFIA, the Stratospheric Observatory for Infrared Astronomy, is an airborne observatory that will study the universe in the infrared spectrum. A Boeing 747-SP aircraft will carry a 2.5 m telescope designed to make sensitive ... -
A critical review on the process of contaminant removal in Fe0-H2O systems.
(Environmental technology, 2008-08-01)
A central aspect of the contaminant removal by elemental iron materials (Fe0 or Fe0 materials) is that reduction reactions are mediated by the iron surface (direct reduction). This premise was introduced by the pioneers ... -
A Dated Holocene Sediment Core from the Bottom of the Southern North Sea
(E&G – Quaternary Science Journal; Vol.35, No. 1)Ein Bohrkern aus der südlichen Nordsee (54° 44,5' N, 4° 30' E) wurde auf Pollen, botanische Makroreste, Mollusken sowie Minerale und Schwermetalle untersucht. Im Liegenden befindet sich ein echter Basistorf, auf den ohne ... -
A Detailed, Multi‐Scale Assessment of an Atmospheric River Event and Its Impact on Extreme Glacier Melt in the Southern Alps of New Zealand
; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-05-02)
North‐westerly airflow and associated atmospheric rivers (ARs) have been found to profoundly influence New Zealand’s west coasts, by causing flooding, landslides and extreme ablation and accumulation on glaciers in the ... -
A discussion on `Domain formation and phase transitions in the wurtzite‐based heterovalent ternaries: a Landau theory analysis'
Quayle, Paul C.; (Acta Crystallographica Section A, 2021-03-23)
Heterovalent ternary nitrides are considered one of the promising classes of materials for photovoltaics, combining attractive physical properties with low toxicity and element abundance. One of the front‐runner systems ... -
A fossil species of the enigmatic early polypod fern genus Cystodium (Cystodiaceae) in Cretaceous amber from Myanmar.
(Scientific reports, 2017-11-06)The monospecific fern genus Cystodium (Cystodiaceae; Polypodiales) occurs exclusively in the tropical forests of the Malay Archipelago, the Admiralty Islands, the Louisiade Archipelago, and the Solomon Islands. Divergence ... -
A fourth order split scheme for elastic wave propagation
(Humboldt-Univ., Berlin2007)Motivated by seismological problems we have studied a 4th order split scheme for the elastic wave equation. We split in the spatial directions and obtain locally one-dimensional systems to be solved. We have analyzed the ... -

A framework for co‐developing conservation research projects with stakeholders: A Lake Victoria case study
; Luomba, Joseph; ; Musobya, Moses; (Lakes & Reservoirs: Research & Management, 2020-12-06)
Stakeholder engagement has increasingly gained popularity in conservation research since it promotes relevant research that has impact and can inform evidence‐based policy. Lake basins can especially benefit from research ...
