Virological and genetic characteristics of human respiratory syncytial viruses isolated in Russia, 2017-2018

open access: yesJournal of Infection in Developing Countries, 2023
Isolation of human respiratory syncytial virus (HRSV) from clinical samples and storage of isolates for long period remains a considerable problem. We describe in detail the optimized conditions of HRSV isolation and cultivation in three cell cultures ...

Channel estimation with Zadoff–Chu sequences in the presence of phase errors

open access: yesElectronics Letters, 2023
Due to their perfect periodic autocorrelation property, Zadoff–Chu sequences are often used as stimulus signals in the measurement of radio channel responses. In this letter, the cross‐correlation of a linear shift‐invariant system's response to a Zadoff–

Insecticide resistance management strategies for public health control of mosquitoes exhibiting polygenic resistance: A comparison of sequences, rotations, and mixtures

open access: yesEvolutionary Applications, 2023
Malaria control uses insecticides to kill Anopheles mosquitoes. Recent successes in malaria control are threatened by increasing levels of insecticide resistance (IR), requiring insecticide resistance management (IRM) strategies to mitigate this problem.

The application of Vavilov’s approaches to the phylogeny and evolution of cultivated species of the genus Avena L.

open access: yesВавиловский журнал генетики и селекции, 2023
The central problem that Vavilov was investigating was the overall concept of global plant genetic resources. The theoretical basis of this concept consisted of the law of homologous series in variation, research on the problem of species as a system ...

Camminare per significare. Riflessioni progettuali sugli incontri nello spazio

open access: yesRi-vista: Ricerche per la Progettazione del Paesaggio, 2022
Walking is a crucial aspect. It is a cognitive act acquired exclusively through direct experience. The movement of the subject across space deeply affects the project. What role can the act of walking play in the construction of a meaning?

Atmospheric River Sequences as Indicators of Hydrologic Hazard in Historical Reanalysis and GFDL SPEAR Future Climate Projections

open access: yesEarth's Future, 2023
When multiple atmospheric rivers (ARs) occur in rapid succession, the combined effect on the hydrologic system can lead to more flooding and damage than would be expected from the individual events. This temporally compounding risk is a source of growing
