Purpose: to study the ¹³⁷Cs migration and concentration in alluvial soils profile radionuclide transfer plants river Unecha floodplain ecosystem. Materials methods. Field studies were carried out 2019–2021 Bryansk region (Klintsovsky district, village of Lopatni, right bank Unecha, current reclamation system). The density contamination territory after Chernobyl accident was 185–555 kBq/m². Conj...

A relatively simple method for preparation of planar nanowire arrays on vicinal substrates by molecular beam epitaxy is presented. The atomic step-and-terrace morphology of vicinal substrates is used to produce a shadowing effect on a highly collimated molecular beam at an oblique incidence to the substrate. The collimation is achieved by placing the evaporation source at a large working distan...

In phylogenomics the analysis of concatenated gene alignments, the so-called supermatrix, is commonly accompanied by the assumption of partition models. Under such models each gene, or more generally partition, is allowed to evolve under its own evolutionary model. Although partition models provide a more comprehensive analysis of supermatrices, missing data may hamper the tree search algorithm...
