Mean Field Type Control With Species Dependent Dynamics via Structured Tensor Optimization

Isabel Haasler, Axel Ringh, Yiqiang Chen

In this letter we consider mean field type control problems with multiple species that have different dynamics. We formulate the discretized problem using a new type of entropy-regularized multimarginal optimal transport problems where the cost is a decomp ...

A new Analleucosma Antoine, 1989 from West Africa (Coleoptera, Scarabaeidae, Cetoniinae)

Michele De Palma

The genus Analleucosma Antoine, 1989 is known from northeastern and southeastern Democratic Republic of Congo and a few localities in East Africa; it currently comprises three similar species, all very scarce in collections. Here I describe a new species, ...

Cellular advective-diffusion drives the emergence of bacterial surface colonization patterns and heterogeneity

Alexandre Louis André Persat, Tamara Rossy

Microorganisms navigate and divide on surfaces to form multicellular structures called biofilms, the most widespread survival strategy found in the bacterial world. One common assumption is that cellular components guide the spatial architecture and arrang ...

Taxonomic revision of genus Fornasinius Bertoloni, 1853 with description of new taxa (Scarabaeidae: Cetoniinae)

Michele De Palma

The genus Fornasinius was established in 1853 by Giuseppe BERTOLONI to receive a taxon that was sufficiently distinct from the known representatives of the genus Goliathus Lamarck, 1801, to merit a different placement. Here, the type species of the genus, ...

Marine and freshwater micropearls: biomineralization producing strontium-rich amorphous calcium carbonate inclusions is widespread in the genus Tetraselmis (Chlorophyta)

Michaël Bensimon, Montserrat Filella

Unicellular algae play important roles in the biogeochemical cycles of numerous elements, particularly through the biomineralization capacity of certain species (e.g., coccolithophores greatly contributing to the "organic carbon pump" of the oceans), and u ...

Comparison of computational methods for the identification of topologically associating domains

Elisa Oricchio, Marie-Pierre Zufferey, Daniele Tavernari, Giovanni Ciriello

BackgroundChromatin folding gives rise to structural elements among which are clusters of densely interacting DNA regions termed topologically associating domains (TADs). TADs have been characterized across multiple species, tissue types, and differentiati ...

Molecular phylogeny suggests transfer of Hemidiscus into Actinocyclus (Coscinodiscales, Coscinodiscophyceae)

Lu Wang

Hemidiscus cuneiformis, type of the family Hemidiscaceae, is a diatom with a distinctive semi-circular shape in valve view. A strain of H. cuneiformis was established from the coastal region of the tropical southwestern Atlantic Ocean off Brazil. Cells of ...

A WebGIS platform for the monitoring of Farm Animal Genetic Resources (GENMON)

Stéphane Joost, Giona Matasci, Ivo Widmer, Solange Catherine Gaillard

Background In 2007, the Food and Agriculture Organization of the United Nations (FAO) initiated the Global plan of action for Farm Animal Genetic Resources (FAnGR). The main goal of this plan is to reduce further loss of genetic diversity in farm animals, ...

Photosymbiosis and the expansion of shallow-water corals

Anders Meibom, Jaroslaw Hubert Stolarski

Roughly 240 million years ago (Ma), scleractinian corals rapidly expanded and diversified across shallow marine environments. The main driver behind this evolution is uncertain, but the ecological success of modern reefbuilding corals is attributed to thei ...

Mobile uranium(IV)-bearing colloids in a mining-impacted wetland

Rizlan Bernier-Latmani, Manon Frutschi, Elena Suvorova Buffat, Yuheng Wang

Tetravalent uranium is commonly assumed to form insoluble species, resulting in the immobilization of uranium under reducing conditions. Here we present the first report of mobile U(IV)-bearing colloids in the environment, bringing into question this commo ...
