Shape Models of Lucy Targets (3548) Eurybates and (21900) Orus from Disk-integrated Photometry

Stephan Hellmich

We use our new light curves, along with historical data, to determine the rotation state, photometric properties, and convex shape models of the targets of the Lucy mission (3548) Eurybates and (21900) Orus. We determine a retrograde spin for both targets, ...

High-throughput DNA barcoding of oligochaetes for abundance-based indices to assess the biological quality of sediments in streams and lakes

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

Aquatic oligochaete communities are valuable indicators of the biological quality of sediments in streams and lakes, but identification of specimens to the species level based on morphological features requires solid expertise in taxonomy and is possible o ...

Barcoding analysis and taxonomic revision of Goliathus Lamarck, 1802 (Scarabaeidae, Cetoniinae)

Michele De Palma

We conducted barcoding analysis of valid taxa in the genus Goliathus Lamarck, 1802 and clarified their relationships. Specimens of Goliathus goliatus (Drury, 1770) sampled in tropical rainforests from Cameroon to Kenya display degrees of genetic and phenot ...

Remarks on the status of Fornasinius insignis ab. funereus Burgeon, 1937 (Coleoptera, Scarabaeidae, Cetoniinae, Goliathini)

Michele De Palma

It was recently proposed that Fornasinius insignis ab. funereus Burgeon, 1937 be raised from the synonymy with Fornasinius fornasini Bertoloni, 1853 and recognized as a good species (Tauzin, 2017). Regrettably, this proposition was based on the misidentifi ...

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

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 ...

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 ...

Spatial variability in longitudinal elastic modulus of clear timber

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin

Different factors such as age, location of timber within the tree, structural imperfections, load history such as wind and snow etc. can affect the material properties of timber taken from the same species, and grown in the same geographical location and l ...

Meta-analysis of incomplete microarray studies

Anthony Christopher Davison, Darlene Goldstein, Alix Corinne Josiane Colette Zollinger

Meta-analysis of microarray studies to produce an overall gene list is relatively straightforward when complete data are available. When some studies lack information, for example, having only a ranked list of genes instead of complete primary data, it is ...

Study of cell differentiation by phylogenetic analysis using histone modification data

Bernard Moret, Philipp Bucher, Yu Lin, Nishanth Ulhas Nair

Background: In cell differentiation, a cell of a less specialized type becomes one of a more specialized type, even though all cells have the same genome. Transcription factors and epigenetic marks like histone modifications can play a significant role in ...

The Contact Process : Competition Models and Boolean Networks

Daniel Rodrigues Valesin

This work is a study of three interacting particle systems that are modified versions of the contact process. The contact process is a spin system defined on a graph and is commonly taken as a model for the spread of an infection in a population; transmiss ...

Charge storage at the Pt/YSZ interface

Christos Comninellis, György Foti, Cyril Falgairette, Arnaud Jaccoud

The electrochemical behavior of Pt/YSZ electrodes in oxygen containing atmosphere at 450 A degrees C has been investigated by double-step chronoamperometry and programmed linear sweep cyclic voltammetry. The response of the O-2(g),Pt/YSZ system in these ex ...
