Supplementary Material - AL2: Progressive Activation Loss for Learning General Representations in Classification Neural Networks

Sabine Süsstrunk, Majed El Helou, Frederike Dümbgen

In this supplementary material, we present the details of the neural network architecture and training settings used in all our experiments. This holds for all experiments presented in the main paper as well as in this supplementary material. We also show ...

Role of photosymbiosis in the Late Triassic expansion of shallow-water Scleractinia

Anders Meibom

Since their appearance in the Anisian (ca. 240 Ma) scleractinian corals rapidly diversified and expandedacross shallow marine environments, becoming the main builders of reefs. This ecological success coralsowe to their symbiotic relationship with photosyn ...

Geochemistry, geothermometry and influence of the concentration of mobile elements in the chemical characteristics of carbonate-evaporitic thermal systems. The case of the Tiermas geothermal system (Spain)

The Tiermas low temperature geothermal system, hosted in the Paleocene-Eocene carbonates of the Jaca-Pamplona basin, has been studied to evaluate the geochemistry and the temperature of the waters in the deep reservoir. These waters are of chloride-sodium ...

Anthropogenic- and natural sources of dust in peatland during the Anthropocene

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

As human impact have been increasing strongly over the last decades, it is crucial to distinguish human-induced dust sources from natural ones in order to define the boundary of a newly proposed epoch -the Anthropocene. Here, we track anthropogenic signatu ...

EEG source imaging of brain states using spatiotemporal regression

Dimitri Nestor Alice Van De Ville, Christoph Michel

Relating measures of electroencephalography (EEG) back to the underlying sources is a long-standing inverse problem. Here we propose a new method to estimate the EEG sources of identified electrophysiological states that represent spontaneous activity, or ...

Effects of an extended drought period on physiological properties of grassland species in the field

Constant Signarbieux

A very high percentage (around 70%) of the agronomic area in Switzerland is covered by grasslands at various altitudes where environmental conditions, management, community structure and productivity vary widely. As heat waves and drought are predicted to ...

Sedimentological processes in the Rhone Delta subaquatic canyons (France-Switzerland)

Nicolas Le Dantec

Deltas are very sensitive environments and highly vulnerable to variations in water discharge and the amount of suspended sediment load provided by the delta-forming currents. Human activities in the watershed, such as building of dams and irrigation ditch ...

Fiber optic distributed temperature sensing for the determination of the nocturnal atmospheric boundary layer height

Wolf Hendrik Huwald, Marc Parlange

A new method for measuring air temperature profiles in the atmospheric boundary layer at high spatial and temporal resolution is presented. The measurements are based on Raman scattering distributed temperature sensing (DTS) with a fiber optic cable attach ...

On the suitability of partially clathrated ice for analysis of concentration and δ13C of palaeo-atmospheric CO2

Jérôme Chappellaz

The description of rapid climatic changes during the last glacial period at high northern latitudes has been largely documented through Greenland ice cores that are unique climatic and environmental records. However, Greenland ice isotopic records are bias ...
