Floristic novelties in the context of interdisciplinary studies
Nowa days, interdisciplinary studies are increasingly important. Integration of botany with humanities, particularly with archaeology and ethnology, is amongst these studies. It is noteworthy that, as a result of such surveys, not only “synthetic” new data could be obtained, but also data in the specific fields of knowledge that compose these multidisciplinary complexes. Thus, during the archaeo- and ethnobotanical studies in Armenia in 2017–2021, along with the data on plant resources, little-known phytonyms, etc., some new floristic data were also recorded regarding the following species: Amaranthus graecizans L., A. hybridus L., Chamaenerion angustifolium (L.) Scop., Diospyros lotus L., Eleocharis palustris (L.) Roem. & Schult., Heracleum trachyloma Fisch. & C.A. Mey., Humulus lupulus L., Hippophae rhamnoides L., Polygonatum orientale Desf., and Ranunculus lateriflorus DC. Earlier, we also procured new data on the phytogeography for such species as Crataegus × armena Pojark., Ephedra procera Fisch. & C.A. Mey., Erodium ciconium (L.) L’Hér., Leonurus cardiaca L., Leucanthemum vulgare L., Matricaria matricarioides (Less.) Porter ex Britt., Neslia paniculata (L.) Desv., Origanum vulgare L., Salvia nemorosa L., Thymus eriophorus Ronn., Th. transcaucasicus Ronn., Tripleurospermum caucasicum (Willd.) Hayek, and T. parviflorum (Willd.) Pobed. Among the species, for which phytogeographic and floristic novelties were recorded, are crop wild relatives, endemics, and rare species, included in the IUCN list. Summarizing the findings, it can be stated that archaeo- and ethnobotany are productive not only in their interdisciplinary, “hybrid” results but also in the disciplines they both synthesize. This is the evidence that interdisciplinary approaches are highly efficient for research, demonstrating a mutually enhanced, i.e., synergistic effect in complex studies
Regulation of Transfer of 137cs by Polymeric Sorbents for Grow Ecologically Sound Biomass
Soil contamination with radiocesium has a long-term radiological impact due to its long physical half-life (30.1 years for 137Cs and 2 years for 134Cs) and its high biological availability. 137Cs causes the largest concerns because of its deleterious effect on agriculture and stock farming, and, thus, human life for decades. One of the important aspects of the problem of contaminated soils remediation is understand of protective actions aimed at the reduction of biological migration of radionuclides in soil-plant system. The most effective way to bind radionuclides is the use of selective sorbents. The proposed research mainly aims to achieve control on transfer of 137Cs in a system growing media–plant due to counter ions variation in the polymeric sorbents. As the research object, Japanese basil-Perilla frutescens was chosen. Productivity of plants depending on the presence (control-without presence of polymer) and type of polymer material, as well as content of 137Cs in plant material has been determined. The character of different polymers influences on the 137Cs migration in growing media–plant system as well as accumulation in the plants has been cleared up

Forbush decrease observed by SEVAN particle detector network on November 4, 2021
On November 3-4 2021, an interplanetary coronal mass injection (ICME) hits
the magnetosphere, sparking a strong G3-class geomagnetic storm and auroras as
far south as California and New Mexico. All detectors of the SEVAN network
registered a Forbush decrease (FD) of 5-10 percentdeep in 1 minute time series
of count rates. We present the results of a comparison of Fd registered on
mountain altitudes on Aragats (Armenia), Lomnicky Stit (Slovakia), Musala
(Bulgaria), and at sea level DESY (Hamburg, Germany), and in Mileshovka,
Czechia. We present as well purity and barometric coefficients of different
coincidences of SEVAN detector layers on Aragats. We demonstrate disturbances
of the near-surface electric (NSEF) and geomagnetic fields at the arrival of
the ICME on Earth
Authentication of electronics components for cyber-physical systems
One of the main directions of cyber-physical systems safety ensuring is the creation and implementation of technologies for providing the electronics components a resistance to various types of external influences. The relevance of this problem is the increase of a rate of counterfeit products in electronics as an international trend. This determines a need to authenticate the products intended for responsible applications. In addition to the issue of counterfeit, the electronics components authentication is necessary for a reliable and informative assessment of their resistance to the impacts from external factors. One of the main tasks of the methodology for assessing the resistance is to establish an effective optimal balance between the reliability of the test results and the procedure laboriousness. The difficulties of this optimization are related mainly to the number of destroyed samples, the volume of collected information, ensuring of a counterfeit identification. Hereby we present an effective authentication procedure combining the "destructive" and "non-destructive" types of checks with the counterfeit identification, sample heterogeneity, and suspicious items. Improvement of the sampling procedure for testing is presented as well. The experimental results of authentication are discussed
Resilience in the mountains: biocultural refugia of wild food in the Greater Caucasus Range, Azerbaijan
Diversity of traditional ecological knowledge (TEK) created on the edges of culture is the key to the sustainability and resilience of humankind. We recorded wild food TEK among seven autochthonous linguistic communities living on both sides of the Greater Caucasus Range, documenting the use of 72 wild taxa as well as remarkable diversity of both taxa and uses among the communities. The most isolated communities form distinct biocultural refugia for wild food plants and their uses, but the sustainability of such communities is under threat due to depopulation, and their TEK has already entered into decline. While isolation may have been responsible for the preservation of food biocultural refugia, it may no longer be enough for the passive preservation of the food refugia in the study area in the future. More proactive steps have to be taken in order to ensure the sustainability of TEK of the study communities and beyond

The place of millet in food globalization during Late Prehistory as evidenced by new bioarchaeological data from the Caucasus
Two millets, Panicum miliaceum and Setaria italica, were domesticated in northern China, around 6000 BC. Although its oldest evidence is in Asia, possible independent domestication of these species in the Caucasus has often been proposed. To verify this hypothesis, a multiproxy research program (Orimil) was designed to detect the first evidence of millet in this region. It included a critical review of the occurrence of archaeological millet in the Caucasus, up to Antiquity; isotopic analyses of human and animal bones and charred grains; and radiocarbon dating of millet grains from archaeological contexts dated from the Early Bronze Age (3500–2500 BC) to the 1st Century BC. The results show that these two cereals were cultivated during the Middle Bronze Age (MBA), around 2000–1800 BC, especially Setaria italica which is the most ancient millet found in Georgia. Isotopic analyses also show a significant enrichment in 13C in human and animal tissues, indicating an increasing C4 plants consumption at the same period. More broadly, our results assert that millet was not present in the Caucasus in the Neolithic period. Its arrival in the region, based on existing data in Eurasia, was from the south, without excluding a possible local domestication of Setaria italica
