Recently discovered amber-preserved fossil Cicadellidae exhibit combinations of morphological traits not observed in the modern fauna and have the potential to shed new light on the evolution of this highly diverse family. To place the fossils explicitly within a phylogenetic context, representatives of five extinct genera from Cretaceous Myanmar amber, and one from Eocene Baltic amber were incorporated into a matrix comprising 229 discrete morphological characters and representatives of all modern subfamilies. Phylogenetic analyses yielded well resolved and largely congruent estimates that support the monophyly of most previously recognized cicadellid subfamilies and indicate that the treehoppers are derived from a lineage of Cicadellidae. Instability in the morphology-based phylogenies is mainly confined to deep internal splits that received low branch support in one or more analyses and also were not consistently resolved by recent phylogenomic analyses. Placement of fossil taxa is mostly stable across analyses. Three new Cretaceous leafhopper genera, Burmotettix gen. nov., Kachinella gen nov., and Viraktamathus gen. nov., consistently form a monophyletic group distinct from extant leafhopper subfamilies and are placed in Burmotettiginae subfam. nov. Extinct Cretaceous fossils previously placed in Ledrinae and Signoretiinae are recovered as sister to modern representatives of these groups. Eomegophthalmus Dietrich and Gonçalves from Baltic amber consistently groups with a lineage comprising treehoppers, Megophthalminae, Ulopinae, and Eurymelinae but its position is unstable. Overall, the morphology-based phylogenetic estimates agree with recent phylogenies based on molecular data alone suggesting that morphological traits recently used to diagnose subfamilies are generally informative of phylogenetic relationships within this group.

A morphology‐based phylogenetic analysis of the tribe Empoascini (Hemiptera: Cicadellidae: Typhlocybinae) is presented for 58 of 83 formerly recognized genera based on 99 morphological characters of adults. The results support excluding the New World Beamerana generic group from Empoascini. The remaining genera of Empoascini were recovered as a monophyletic sister group of Dikraneurini. Previously recognized tribes Jorumini and Helionini are derived from within Empoascini and are considered synonyms of the latter tribe. Three previously recognized informal generic groups, the Empoasca group, Alebroides group and Usharia group were paraphyletic but the Ficiana group was recovered as monophyletic based on five synapomorphies. Genera previously placed in the Alebroides group represent at least six independent lineages, indicating that the hind wing character separating this group from the Empoasca group (CuA and MP veins free) is highly homoplasious. Empoasca (sensu lato) is also paraphyletic. Thus, twelve previously recognized subgenera of Empoasca are elevated to genus status and five species groups of Empoasca from the New World are recognized as separate new genera. Sikkimasca Dworakowska, 1993 is treated as synonym of Marolda Dworakowska, 1977 based on the phylogeny. Biogeographic analysis suggests that Empoascini most likely first evolved in the Oriental region and spread to other biogeographic realms more recently by multiple independent invasions.

The development of network based on satellite communication systems is a promising solution for providing telecommunications services in the Arctic. Therefore, the task of developing and creating earth stations for advanced satellite communication systems that have characteristics significantly higher than their world counterparts is actual. Characteristics of such stations depend on antenna’s systems characteristics that determine the energy characteristics of the communication channel. The aim of this work is a stand developing for measuring directional characteristics of antennas of satellite communication systems based on the spherical scanner (TS8991). Spiral scanning is an alternative measurement method aimed at reducing measurement time with saving necessary accuracy. As a result of this work, the spiral scanning algorithm based on the near-field scanner Rohde & Schwarz TS8991 was implemented. Moreover, the stand for monitoring and configuring the parameters of satellite earth station antennas was built. Block diagram of this stand is presented in article. An antenna with 1,2 m diameter of reflector was tested on the developed stand. The measurement results showed deviations of the measured values from the calculated values, which related by design disadvantages of the antenna. The stand using time was 35 minutes for measurements and conversions to the far field, for an antenna with 1,2 m diameter of reflector.

Many tasks of digital signal processing require the implementation of matrix operations in real time. These are operations of matrix inversion or solving systems of linear algebraic or dif- ferential equations (Kalman filter). The transition to the implementation of digital signal processing on programmable logic device (FPGAs), as a rule, involves calculations based on the representation of numbers with a fixed point. This makes solving spatio-temporal processing problems practically im- possible based on conventional computational methods. The article discusses the implementation of spatial-temporal signal processing algorithms in satellite broadband systems using QR decomposition. The technologies of CORDIC computations required for recurrent QR decomposition when used together in systolic algorithms are presented

Rovnoxestus rasnitsyni gen. & sp. nov. is described from Eocene Rovno amber based on an adult female and fifth-instar nymph collected at a recently discovered locality at Perebrody, Rovno Province, Ukraine. The new fossil taxon is tentatively placed in Aphrodinae and resembles Xestocephalites Dietrich & Gonçalves from Eocene Baltic amber but has the hind femur macrosetal formula 2+2+1 and hind tarsomere I in both nymph and adult with an elongated inner preapical seta. This is the first species of Eocene leafhopper for which both the adult and nymph are described in detail.

TaxonWorks is an integrated web-based application for practicing taxonomists and biodiversity specialists. It is focused on promoting collaboration between researchers and developers. TaxonWorks has a modular structure that enables various components of the application to target specific needs and requirements of different groups of users. Specific areas of interest may include nomenclature-related tasks (Yoder and Dmitriev 2021) designed to help assemble and validate scientific name checklists of a target group of organisms; and collection management tasks, including interfaces to create, filter, and edit collecting events, collection objects, and loans. This presentation focuses on matrix-related tools integrated into TaxonWorks. A matrix, which could either be used for phylogenetic analysis or to build an identification key, is structured as a table where columns represent numerous characters that could be used to describe a set of entities, taxa or specimens (presented as rows of the table). Each cell of the table may contain observations for specific character/entity combinations. TaxonWorks does not generate a table for each a particular matrix—all observations are stored as graphs. This structure allows building of a matrix of an unlimited size as well as reuse of individual observations in multiple matrices. For matrix columns, TaxonWorks supports a variety of different kinds of characters or descriptors: qualitative, presence/absence, quantitative, sample, gene, free text, and media. Each character may have specific properties, for example a qualitative descriptor may have numerous characters states, and a quantitative descriptor may have a measurement unit defined. For an entity in a matrix row, TaxonWorks supports either collection objects (specimens) or taxa as Operational Taxonomic Units (OTU). OTUs could either be linked to nomenclature or be stand alone entities (e.g., representing undescribed species). The matrix, once built, could serve several purposes. A matrix based on qualitative and quantitative characters could be used to build an interactive key (Fig. 1), construct standardized natural language descriptions for each entity, and determine a diagnosis (a minimal set of characters that separate one entity from all others). It could also be exported and used for phylogenetic analysis or to build an interactive key in an external application. TaxonWorks supports export files in several formats, including Nexus, TNT, NeXML. Application Programming Interfaces (API) are also available. A matrix based on media descriptors could be used as a pictorial identification tool (Fig. 2).

We are now over four decades into digitally managing the names of Earth's species. As the number of federating (i.e., software that brings together previously disparate projects under a common infrastructure, for example TaxonWorks) and aggregating (e.g., International Plant Name Index, Catalog of Life (CoL)) efforts increase, there remains an unmet need for both the migration forward of old data, and for the production of new, precise and comprehensive nomenclatural catalogs. Given this context, we provide an overview of how TaxonWorks seeks to contribute to this effort, and where it might evolve in the future. In TaxonWorks, when we talk about governed names and relationships, we mean it in the sense of existing international codes of nomenclature (e.g., the International Code of Zoological Nomenclature (ICZN)). More technically, nomenclature is defined as a set of objective assertions that describe the relationships between the names given to biological taxa and the rules that determine how those names are governed. It is critical to note that this is not the same thing as the relationship between a name and a biological entity, but rather nomenclature in TaxonWorks represents the details of the (governed) relationships between names. Rather than thinking of nomenclature as changing (a verb commonly used to express frustration with biological nomenclature), it is useful to think of nomenclature as a set of data points, which grows over time. For example, when synonymy happens, we do not erase the past, but rather record a new context for the name(s) in question. The biological concept changes, but the nomenclature (names) simply keeps adding up. Behind the scenes, nomenclature in TaxonWorks is represented by a set of nodes and edges, i.e., a mathematical graph, or network (e.g., Fig. 1). Most names (i.e., nodes in the network) are what TaxonWorks calls "protonyms," monomial epithets that are used to construct, for example, bionomial names (not to be confused with "protonym" sensu the ICZN). Protonyms are linked to other protonyms via relationships defined in NOMEN, an ontology that encodes governed rules of nomenclature. Within the system, all data, nodes and edges, can be cited, i.e., linked to a source and therefore anchored in time and tied to authorship, and annotated with a variety of annotation types (e.g., notes, confidence levels, tags). The actual building of the graphs is greatly simplified by multiple user-interfaces that allow scientists to review (e.g. Fig. 2), create, filter, and add to (again, not "change") the nomenclatural history. As in any complex knowledge-representation model, there are outlying scenarios, or edge cases that emerge, making certain human tasks more complex than others. TaxonWorks is no exception, it has limitations in terms of what and how some things can be represented. While many complex representations are hidden by simplified user-interfaces, some, for example, the handling of the ICZN's Family-group name, batch-loading of invalid relationships, and comparative syncing against external resources need more work to simplify the processes presently required to meet catalogers' needs. The depth at which TaxonWorks can capture nomenclature is only really valuable if it can be used by others. This is facilitated by the application programming interface (API) serving its data (https://api.taxonworks.org), serving text files, and by exports to standards like the emerging Catalog of Life Data Package. With reference to real-world problems, we illustrate different ways in which the API can be used, for example, as integrated into spreadsheets, through the use of command line scripts, and serve in the generation of public-facing websites. Behind all this effort are an increasing number of people recording help videos, developing documentation, and troubleshooting software and technical issues. Major contributions have come from developers at many skill levels, from high school to senior software engineers, illustrating that TaxonWorks leads in enabling both technical and domain-based contributions. The health and growth of this community is a key factor in TaxonWork's potential long-term impact in the effort to unify the names of Earth's species.

The article is devoted to the study how podcasts can motivate students to study a foreign language. Having analyzed research by both domestic and foreign scientists, the authors reveal the essence of the concept “podcast”, describe the didactic capabilities of podcasts and characterize the types of motivation necessary for learning a foreign language. It was revealed that more than half of the 1st year students studying at the university after college do not have the necessary motives for improving the foreign language and believe that they have already received all the necessary skills in college. Podcasts were introduced into the educational process to solve this problem. In the article the authors describe the experience of using podcasts to create students’ motivation to learn English. Podcasts were used while teaching the English language in the university and in the process of students’ independent work during the whole semester. The study showed that podcasts are a powerful motivational tool, involving a large number of students into the process of learning the English language and making this process interesting, informative and effective.

The measured width of the highfrequency stop band of 24 times the center frequency of the bandwidth at the level of suppression at least 160 dB

Modern GNSS navigation equipment has a significant drawback — low noise immunity. To solve this problem, they are based on phased array antennas using adaptive signal processing algorithms. The final effect of such processing is determined by the level and completeness of using the existing differences, as well as the quality of accounting for each of them, depending on the degree of fame of the statistical characteristics of signals and interference. The article discusses the theory of synthesis of an algorithm for measuring the parameters of radio navigation signals received on spaced antennas under the influence of interference

In the article the results of experimental studies of the power amplifier Q-band chip-based NC116150C-4345P10. This microcircuit is made on the basis of gallium nitride (GaN) technology and has high reliability, efficiency, and relatively low cost. In the production of power amplifiers GaN technology has been widely used due to the high breakdown voltage of a wide band gap [1]–[4]. The Q-band is still rather poorly mastered and the study of the characteristics of amplifiers at these frequencies is fraught with some difficulties. The paper presents a technique for measuring the characteristics of a power amplifier in the Q- band. The schemes for measuring the linear and amplitude characteristics of the amplifier, the results of experimental studies and signal spectra at the maximum output power of the amplifier are presented. An experimental study of the characteristics of the amplifier made it possible to determine the possibility of its application in satellite communication systems, when calculating the energy potential of the Earth-satellite radio link and the reliability of the satellite channel.

The issues of forming the required radiation pattern of an adaptive antenna array for scanning the atmosphere using small-element antennas in vertical sensing radars are considered in the article. These radars operate in pulsed mode and use Fresnel and Bragg Scattering from turbulent formations and various reflections of electromagnetic waves in various atmosphere layers. Low-element adaptive antenna arrays have low cost, high mobility and low hardware costs for organizing atmospheric scanning. The subject of intensive research is adaptive antenna arrays application in radar and radio navigation systems. It allows to form the required directional pattern, to electrically scan the space by changing the amplitude-phase distribution on the adaptive antenna arrays elements, to increase the probability of receiving useful signal, including signals reception against the background of multipath. The results of modeling special radiation patterns for different configurations of antenna arrays with a small number of antenna elements are presented.

The measurements were made with a spherical scanner using the spiral scanning method.

In 2009, Jones and Deitz published a tribe-level taxonomic revision and reclassification of the cryptic, arboreal leafhopper subfamily Ledrinae Kirschbaum, 1868 (Hemiptera: Cicadellidae), based on cladistic analyses of 235 morphological features for 75 cicadellid species. Their evolutionary reconstructions found strong node support for a monophyletic ingroup comprising five lineages—each morphologically and geographically cohesive—and also identified numerous traditionally placed taxa (sensu Oman et al 1990) that did not belong. In light of the robustness of their results, the authors recognized the five independent ingroup clades as tribes of Ledrinae, and described three of these as new.

TaxonWorks is a web-based workbench facilitating curation of a broad cross-section of biodiversity informatics concepts. Its development is currently led by the Species File Group. TaxonWorks has a large, JSON serving, application programming interface (API). This API is slowly being exposed for external use. The API is documented at https://api.taxonworks.org. Here we highlight some existing key features of the API focusing on the TaxonWorks concepts of People, Sources, Collection Objects, Taxon Names, and Downloads and provide a brief roadmap for upcoming additions. Highlights include the ability for data curators to produce shareable bibliographies, DarwinCore Archives (DwC-A), and Catalogue of Life-formatted datasets, access their nomenclature as autocompletes and via many filter facets, share Person metadata including numerous identifier types, and perform basic Geo-JSON and simple DwC-A parameter-based filtering on Collection Objects. As examples of what can be done with the API, we provide several visualizations that are straightforward to implement by those with basic R, Python, Javascript, or Ruby programming skills.

We consider the strongly anisotropic spin-1/2 $XXZ$ model on the sawtooth-chain lattice with ferromagnetic longitudinal interaction $J^{zz}=\Delta J$ and aniferromagnetic transversal interaction $J^{xx}=J^{yy}=J>0$. At $\Delta=-1/2$ the lowest one-magnon excitation band is dispersionless (flat) leading to a massively degenerate set of ground states. Interestingly, this model admits a three-coloring representation of the ground-state manifold [H.~J.~Changlani et at., Phys. Rev. Lett. {\bf 120}, 117202 (2018)]. We characterize this ground-state manifold and elaborate the low-temperature thermodynamics of the system. We illustrate the manifestation of the flat-band physics of the anisotropic model by comparison with two isotropic flat-band Heisenberg sawtooth chains. Our analytical consideration is complemented by exact diagonalization and finite-temperature Lanczos method calculations., Comment: 12 pages,8 figures

The growing number of subscribers and the volume of transmitted information requires an increase in the capacity of satellite communication systems. This is possible through the use of high orders of signal constellations, spatial separation of channels, effective noise-resistant codes. In addition, the new standards require the effective use of nonlinear power amplifiers that must operate close to saturation. Of interest is the increase in the capacity of satellite communication systems due to the multi-frequency mode in the transponder channel. The article reveals the channel structure, gives a detailed description of the input and output multiplexers, a nonlinear amplifier, a mixer, and a local oscillator. The structure of the computer model of the transponder channel and the multi-frequency signal of the ground station is shown. The simulation results show that the multi-frequency mode introduces additional intermodulation distortion of the carriers of one channel. This requires the development of nonlinear predistortion systems at transmitting ground stations, as well as equalizers at receiving stations.

The article discusses the methods of mutual high-precision navigation of multi-satellite clusters of small spacecraft.

Dynamic and non-retrieval methods are considered.

Measurement of the state of the atmosphere is the most important task in the field of meteorology. Information on wind speed and direction at different heights, magnitude of turbulence and atmospheric tide is necessary for ensuring aviation safety, and the accident-free movement of land and sea vehicles. Vertical sensing radars are used to obtain information on the dynamics of atmospheric movements. They use reflections of electromagnetic waves from turbulent formations in the layers of the atmosphere and formations of a different nature. The time position of the reflected signal and the frequency shift due to the Doppler effect provide accurate information about the height and speed of movement of atmospheric inhomogeneities. An analysis of the parameters of the reflected signals makes possible to obtain in real time the altitude-time field of the wind speed and turbulence intensity. The physical principles underlying the operation of these radars allow continuous measurements regardless of weather conditions. The basic methods for measuring the vertical profile of the atmosphere, methods of scanning and classification of means of sensing for the vertical profile of the atmosphere, and the features of the operation and construction of vertical sensing radars with a low-element array are considered. The result of atmospheric sensing by a radar station with a low-element antenna array is presented.

This paper is devoted to actual problems of seismic analysis of underground structures. Brief classification and overview of corresponding methods of analysis (force-based methods, displacement-based methods, numerical methods of seismic analysis of coupled system “soil – underground structure” and approaches to problems of soil-structure interaction) is presented. Special static finite element method with substructure technique for seismic analysis of underground structures is described. Dynamic soil-structure interaction system can be decomposed into three sub-structures: structure, near-field and far-field soil. The first stage of static finite element method is solving the free field shear stress, acceleration, velocity and displacement, when the moment that the relative displacement of the soil that the underground structure located in reaches the maximum. The second stage is computing of internal forces and parameters of boundary conditions. The third stage is construction of the static finite element model and imposing the loads and constrains computed at the second stage and then making a static analysis.

Space-time signal processing in adaptive electronic systems, including navigation, remains the subject of intensive research, as it allows to improve the efficiency of receiving useful signals under the influence of natural or intentional interference. The bibliography on this subject is very extensive and includes a large number of articles of scientific and applied nature, dissertations, monographs, patent materials. Much of this work has references to monographs by R. Monzingo and B. Widrow, which set out the basic principles, criteria and algorithms of spatial-temporal signal processing. To date, the development of space-time signal processing is largely constrained by the imperfection of the element base. The use of modern navigation equipment consumers high-speed signal processors that implement advanced methods and algorithms of digital signal processing, provides the ability of digital methods to form the desired beam pattern of the antenna system and to adjust the frequency characteristics of the reception channels, to implement complex algorithms for optimal processing of useful signals, operative to control the main operation modes of equipment. One of the most important applications of space-time signal processing is noise suppression, and its effectiveness depends on the degree of inter-channel correlation of these signals received by antenna elements of the adaptive antenna array. To maximize the coefficient of interference suppression required the adoption of measures on alignment of frequency and phase characteristics of the receiving circuits, and high precision computation of weighting coefficients. The article considers the questions of spatial filtering of the interference when adaptive interference compensator adjusted frequency characteristics of the receiving channels, and means of satellite navigation. Gradient algorithm of spatial compensation of noise, and also influence of adaptive correction of frequency characteristics of receiving channels on quality of suppression of noise is presented. The formation of a directional diagram of a multi-element adaptive antenna array with spatial noise suppression is demonstrated by modeling in the Matlab environment.

It is assumed that the socalled "One Tower" skyscraper with a height of 403.9 meters, considered in the distinctive paper, will be located in the Moscow International Business Center (MIBC) and will become one of the tallest buildings in Europe. The project of a unique object was developed in the architectural bureau "Sergey Skuratov Architects" and "GKTtechStroy" LLC (under the direction of M.I. Kelman). Generally the paper is devoted to computational studies of the stress-strain state, strength and stability ofload-bearing structures of this multifunctional residential complex with an underground parking lot. The paper provides a brief description of the natural conditions of the area of the location of the object, its load-bearing structures, characteristic and design loads, their combinations. Besides, formulation of objectives of computational research is presented. Then numerical methods, algorithms and software, which were used for computational static and dynamic analysis of skyscraper and analysis of corresponding stress-strain state are described. Further, the developed and verified advanced detailed finite element model of the coupled system "pile foundation - load­bearing structures of residential building" is considered. This model adequately reflects corresponding geometric, stiffness, inertial and load parameters and the resulting stress-strain state. Resulting parameters of the stress-strain state, strength and dynamics of load-bearing structures of "One Tower" sky­scraper with allowance for design (in accordance with design codes) combinations of vertical and wind loads and progressive collapse analysis are under consideration as well. As a result a reasonable conclusion is made about the reliability of the criterion parameters obtained by structural analysis including strength analysis, stability analysis and dynamic analysis of the loadbearing structures of the building. Computational structural analysis was performed with the use of licensed certified finite element software package ANSYS Mechanical, verified by the Russian Academy of Architecture and Construction Sciences (RAACS). Reinforcement of structures was designed in "OM SNiP Zhelezobeton" software after converting of resultant efforts from ANSYS Mechanical.
