Concordance of the spectral properties of dorsal wing scales with the phylogeographic structure of European male Polyommatus icarus butterflies
Authors: Piszter Gábor , Kertész Krisztián , Sramkó Gábor , Krízsik Virág , Bálint Zsolt , Biró László Péter
Published: August 2021

The males of more than 80% of the Lycaenidae species belonging to the tribe Polyommatini exhibit structural coloration on their dorsal wing surfaces. These colors have a role in reinforcement in prezygotic reproductive isolation. The species-specific colors are produced by the cellular self-assembly of chitin/air nanocomposites. The spectral position of the reflectance maximum of such photonic nanoarchitectures depends on the nanoscale geometric dimensions of the elements building up the nanostructure. Previous work showed that the coloration of male Polyommatus icarus butterflies in the Western and Eastern Palearctic exhibits a characteristic spectral difference (20 nm). We investigated the coloration and the de novo developed DNA microsatellites of 80 P. icarus specimens from Europe from four sampling locations, spanning a distance of 1621 km. Remarkably good concordance was found between the spectral properties of the blue sexual signaling color (coincident within 5 nm) and the population genetic structure as revealed by 10 microsatellites for the P. icarus species.

Published: August 2021

Heat shock transcription factors (HSFs) are central elements in the regulatory network that controls plant heat stress response. They are involved in multiple transcriptional regulatory pathways and play important roles in heat stress signaling and responses to a variety of other stresses. We identified 41 members of theHSFgene family in moso bamboo, which were distributed non-uniformly across its 19 chromosomes. Phylogenetic analysis showed that the moso bambooHSFgenes could be divided into three major subfamilies;HSFsfrom the same subfamily shared relatively conserved gene structures and sequences and encoded similar amino acids. AllHSFgenes contained HSF signature domains. Subcellular localization prediction indicated that about 80% of the HSF proteins were located in the nucleus, consistent with the results of GO enrichment analysis. A large number of stress response–associatedcis-regulatory elements were identified in theHSFupstream promoter sequences. Synteny analysis indicated that theHSFsin the moso bamboo genome had greater collinearity with those of rice and maize than with those of Arabidopsis and pepper. Numerous segmental duplicates were found in the moso bambooHSFgene family. Transcriptome data indicated that the expression of a number ofPeHsfs differed in response to exogenous gibberellin (GA) and naphthalene acetic acid (NAA). A number ofHSFgenes were highly expressed in the panicles and in young shoots, suggesting that they may have functions in reproductive growth and the early development of rapidly-growing shoots. This study provides fundamental information on members of the bambooHSFgene family and lays a foundation for further study of their biological functions in the regulation of plant responses to adversity.

Published: August 2021

The present study investigated the interactive effects of three environmental stress factors elevated CO2, temperature, and drought stress on soybean growth and yield. Experiments were conducted in the sunlit, controlled environment Soil–Plant–Atmosphere–Research chambers under two-level of irrigation (WW-well water and WS-water stress-35%WW) and CO2 (aCO2-ambient 400 µmol mol−1 and eCO2-elevated 800 µmol mol−1) and each at the three day/night temperature regimes of 24/18 °C (MLT-moderately low), 28/22 °C (OT-optimum), and 32/26 °C (MHT-moderately high). Results showed the greatest negative impact of WS on plant traits such as canopy photosynthesis (PCnet), total dry weight (TDwt), and seed yield. The decreases in these traits under WS ranged between 40 and 70% averaged across temperature regimes with a greater detrimental impact in plants grown under aCO2 than eCO2. The MHT had an increased PCnet, TDwt, and seed yield primarily under eCO2, with a greater increase under WW than WS conditions. The eCO2 stimulated PCnet, TDwt, and seed yield more under WS than WW. For instance, on average across T regimes, eCO2 stimulated around 25% and 90% dry mass under WW and WS, respectively, relative to aCO2. Overall, eCO2 appears to benefit soybean productivity, at least partially, under WS and the moderately warmer temperature of this study.

Published: August 2021

Plant diseases caused by plant viruses and pathogens seriously affect crop yield and quality, and it is very difficult to control them. The discovery of new leads based on natural products is an important way to innovate pesticides. Based on the resveratrol is a kind of natural phytoalexin, but it cannot be used as candidate for the development of new drug due to its poor druggability. The phenolic hydroxyl groups in the resveratrol structure are easily destroyed by oxidation, in order to improve its stability, ester formation is the most commonly used modification method in drug design. Their structures were characterized by1H NMR,13C NMR and HRMS. The activity against tobacco mosaic virus (TMV) of these ester derivatives has been tested for the first time. The bioassay results showed part of the target compounds exhibited good to excellent in vivo activities against TMV. The optimum compoundsIII-2(inhibitory rates of 50, 53, and 59% at 500 μg/mL for inactivation, curative, and protection activities in vivo, respectively),III-4(inhibitory rates of 57, 59, and 51% at 500 μg/mL, respectively), andII-5(inhibitory rates of 54, 52, and 51% at 500 μg/mL, respectively) displayed higher activity than commercial plant virucide ribavirin (inhibitory rates of 38, 37, and 40% at 500 μg/mL, respectively). CompoundsI-9andI-10also showed excellent activities. The systematic study provides strong evidence that these simple resveratrol derivatives could become potential TMV inhibitors. The novel concise structure provides another new template for antiviral studies.
Conditions for walk-off soliton generation in a multimode fiber
Authors: Zitelli Mario , Mangini Fabio , Ferraro Mario , Sidelnikov Oleg , Wabnitz Stefan
Published: August 2021

It has been recently demonstrated that multimode solitons are unstable objects which evolve, in the range of hundreds of nonlinearity lengths, into stable single-mode solitons carried by the fundamental mode. We show experimentally and by numerical simulations that femtosecond multimode solitons composed by non-degenerate modes have unique properties: when propagating in graded-index fibers, their pulsewidth and energy do not depend on the input pulsewidth, but only on input coupling conditions and linear dispersive properties of the fiber, hence on their wavelength. Because of these properties, spatiotemporal solitons composed by non-degenerate modes with pulsewidths longer than a few hundreds of femtoseconds cannot be generated in graded-index fibers.

Published: August 2021

In response to unprecedented surges in the demand for hospital care during the SARS-CoV-2 pandemic, health systems have prioritized patients with COVID-19 to life-saving hospital care to the detriment of other patients. In contrast to these ad hoc policies, we develop a linear programming framework to optimally schedule elective procedures and allocate hospital beds among all planned and emergency patients to minimize years of life lost. Leveraging a large dataset of administrative patient medical records, we apply our framework to the National Health Service in England and show that an extra 50,750–5,891,608 years of life can be gained compared with prioritization policies that reflect those implemented during the pandemic. Notable health gains are observed for neoplasms, diseases of the digestive system, and injuries and poisoning. Our open-source framework provides a computationally efficient approximation of a large-scale discrete optimization problem that can be applied globally to support national-level care prioritization policies.

SARS-CoV-2 is a coronavirus that emerged in 2019 and rapidly spread across the world causing a deadly pandemic with tremendous social and economic costs. Healthcare systems worldwide are under great pressure, and there is an urgent need for effective antiviral treatments. The only currently approved antiviral treatment for COVID-19 is remdesivir, an inhibitor of viral genome replication. SARS-CoV-2 proliferation relies on the enzymatic activities of the non-structural proteins (nsp), which makes them interesting targets for the development of new antiviral treatments. With the aim to identify novel SARS-CoV-2 antivirals, we have purified the exoribonuclease/methyltransferase (nsp14) and its cofactor (nsp10) and developed biochemical assays compatible with high-throughput approaches to screen for exoribonuclease inhibitors. We have screened a library of over 5000 commercial compounds and identified patulin and aurintricarboxylic acid (ATA) as inhibitors of nsp14 exoribonuclease in vitro. We found that patulin and ATA inhibit replication of SARS-CoV-2 in a VERO E6 cell-culture model. These two new antiviral compounds will be valuable tools for further coronavirus research as well as potentially contributing to new therapeutic opportunities for COVID-19.
Transcriptional control of ribosome biogenesis in yeast: links to growth and stress signals
Authors: Shore David , Zencir Sevil , Albert Benjamin
Published: August 2021

Ribosome biogenesis requires prodigious transcriptional output in rapidly growing yeast cells and is highly regulated in response to both growth and stress signals. This minireview focuses on recent developments in our understanding of this regulatory process, with an emphasis on the 138 ribosomal protein genes (RPGs) themselves and a group of >200 ribosome biogenesis (RiBi) genes whose products contribute to assembly but are not part of the ribosome. Expression of most RPGs depends upon Rap1, a pioneer transcription factor (TF) required for the binding of a pair of RPG-specific TFs called Fhl1 and Ifh1. RPG expression is correlated with Ifh1 promoter binding, whereas Rap1 and Fhl1 remain promoter-associated upon stress-induced down regulation. A TF called Sfp1 has also been implicated in RPG regulation, though recent work reveals that its primary function is in activation of RiBi and other growth-related genes. Sfp1 plays an important regulatory role at a small number of RPGs where Rap1–Fhl1–Ifh1 action is subsidiary or non-existent. In addition, nearly half of all RPGs are bound by Hmo1, which either stabilizes or re-configures Fhl1–Ifh1 binding. Recent studies identified the proline rotamase Fpr1, known primarily for its role in rapamycin-mediated inhibition of the TORC1 kinase, as an additional TF at RPG promoters. Fpr1 also affects Fhl1–Ifh1 binding, either independently or in cooperation with Hmo1. Finally, a major recent development was the discovery of a protein homeostasis mechanism driven by unassembled ribosomal proteins, referred to as the Ribosome Assembly Stress Response (RASTR), that controls RPG transcription through the reversible condensation of Ifh1.
Dominant inter‐area oscillation path analysis of power systems with a high penetration of permanent magnet synchronous generator by using network mode energy
Authors: Liu Cheng , Yu Siyao , Zhang Yuchi , Diao Shuo , Zhao Xiaoyang
Published: August 2021

In this study, a network mode energy (NME) method is used to analyse the low‐frequency oscillation (LFO) of a power system with a high penetration of a permanent magnet synchronous generator (PMSG). This method is also utilized to determine the dominant inter‐area oscillation path. NME comes from a network potential energy based on a small signal mode, which includes a generator internal node mode potential energy and a line mode potential energy (LMPE). The exchange process and distribution of NME in the power system containing the PMSG are studied by analysing the composition of LMPE. A sensitivity index is constructed to determine the state variables of the generator and the PMSG, which remarkably influences energy distribution. Then, the path characteristics of LFO are analysed. The dominant inter‐area oscillation paths and energy interaction of the system connecting to the PMSG are determined. The proposed NME can be calculated on the basis of measurement information, and network energy decomposition is carried out using the measured line mode oscillation index. The mechanism of PMSG participating in oscillation is revealed from the network perspective to provide a basis for network‐based regulation. The correctness analysis and simulation of a four‐machine two‐area system with the PMSG and the New England 10‐machine 39‐bus system with the PMSG are carried out.

We constrain the luminosity and redshift dependence of the intrinsic alignment (IA) of a nearly volume-limited sample of luminous red galaxies selected from the fourth public data release of the Kilo-Degree Survey (KiDS-1000). To measure the shapes of the galaxies, we used two complementary algorithms, finding consistent IA measurements for the overlapping galaxy sample. The global significance of IA detection across our two independent luminous red galaxy samples, with our favoured method of shape estimation, is ∼10.7σ. We find no significant dependence with redshift of the IA signal in the range 0.2 < z < 0.8, nor a dependence with luminosity belowLr ≲ 2.9 × 1010 h−2Lr, ⊙. Above this luminosity, however, we find that the IA signal increases as a power law, although our results are also compatible with linear growth within the current uncertainties. This behaviour motivates the use of a broken power law model when accounting for the luminosity dependence of IA contamination in cosmic shear studies.
Bayesian inference of three-dimensional gas maps
Authors: Mertsch P. , Vittino A.
Published: August 2021

Carbon monoxide (CO) is the best tracer of Galactic molecular hydrogen (H2). Its lowest rotational emission lines are in the radio regime, and thanks to Galactic rotation, emission at different distances is Doppler shifted. For a given gas flow model, the observed spectra can thus be deprojected along the line of sight to infer the gas distribution. We used the CO-line survey of Dame et al. (2001, ApJ, 547, 792) to reconstruct the three-dimensional density of H2. We considered the deprojection as a Bayesian variational inference problem. The posterior distribution of the gas densities allowed us to estimate the mean and uncertainty of the reconstructed density. Unlike most of the previous attempts, we took the correlations of gas on a variety of scales into account, which allowed us to correct for some of the well-known pathologies, such as finger-of-god effects. The two gas flow models that we adopted incorporate a Galactic bar that induces radial motions in the inner few kiloparsecs and thus offers spectral resolution towards the Galactic centre. We compared our gas maps with those of earlier studies and characterise their statistical properties, for instance the radial profile of the average surface mass density.

As a result of a generalization of 45-year monitoring observations at on the ash dump of the Verkhniy Tagil Power Station, the absolute time scale was made, stabilization rates during succession of different plant communities characteristics were assessed in two areas: recultivated and non-recultivated. Recultivation consisted of clay strips applying (5–8 m wide, 10–15 cm thick) on ash surface. All characteristics of plant communities (total projective cover by plants, total number of species in plant community) are formed 15–20 years faster in recultivated area. So, a simple technical recultivation, (clay strips applying), significantly accelerates the formation of plant communities main characteristics on ash surface in subzone of the southern taiga in Middle Urals.

The article analyzes the research on the formation of the leaf surface area of spring wheat of Darya variety in different cultivation technologies on the chernozem soil of Kursk Region. The aim of the research was to study the peculiarities of the formation of the leaf surface of spring wheat depending on the cultivation technology and to identify the conjugate relationships of indicators under the conditions of chernozem soils of Kursk Region. The results of the conducted studies indicate that intensive cultivation technology contributes to the activation of the assimilation apparatus of leaves during the entire growing season of the crop. A high direct correlation between the leaf surface area in the Z 13 and Z 55 phases and the application of mineral fertilizers was established (r = 0.73; 0.80, respectively). At Z 25 the leaf surface area has a direct noticeable relationship with primary tillage (r = 0.51) and a moderate one with the application of mineral fertilizers (r = 0.36). The use of sugar beet tops as organic fertilizer had a positive effect on the leaf area of one plant at Z 25 and Z 55, as evidenced by a noticeable correlation (r = 0.52; 0.52, respectively). It was found that the area of the flag leaf, as well as its length and width, increased with a decrease in the density of standing plants per square meter of cropped area. The flag leaf area and width decreased depending on the height of the plants, while the length increased. The development of the flag leaf area directly affected the accumulation of dry weight of plants (r = 0.53), the formation of the total assimilation surface of plants (r = 0.72), as well as a high direct relationship with the length of the ear (r = 0.75), which in turn is closely directly correlated with the weight of grain from one ear (r = 0.70). Thus, the evidence of the direct influence of the area of the flag leaf on the formation of the crop yield is presented.

The research was carried out to study the effect of biological preparations (Gribofit and Imunazot), applied both separately and together with nitrogen fertilizers (at the rate of 10 kg of NPPN. per 1 ton of straw) with the use of by-products as fertilizer on crop yield and productivity of the link of the cereal-row crop rotation “sunflower–barley-soybean”. The work was carried out in 2018-2020 in Kursk Region on typical slightly eroded heavy-loamy chernozem. The results are obtained for the following variants: 1. crushed by-products of crop rotation crops (control); 2. crushed by-products of crop rotation crops + nitrogen fertilizers at the rate of 10 kg of NPPN per 1 ton of cereal straw; 3. crushed by-products of crop rotation crops + biological preparations (Gribofit and Imunazot); 4. crushed by-products of crop rotation crops + biological preparations (Gribofit and Imunazot) + nitrogen fertilizers at the rate of 10 kg of NPPN per 1 ton of cereal straw. The results of the studies showed that the application of biological preparations against the background of surface embedded crop by-products provided an increase in the yield of all the crops of the crop rotation link in relation to the control. But higher efficiency was noted when using nitrogen fertilizers against the background of the applied crushed plant residues, it was 10.67 thousand grain units per 1ha, which exceeded the control by 3.19 thousand grain units per 1 ha (42.6%).

Authors: Meleshkina Elena , Bundina Olga
Published: August 2021

In recent years, Russia has made considerable advances in the production and export of grain. Grain production, primarily wheat, is the driver of the country’s economic growth. At the same time, wheat grain has a multipurpose use, it is a valuable multifunctional primary product for obtaining a wide range of production with high added value, consumed by many economic sectors. A paradoxical situation has developed: Russia is the world’s largest exporter of grain – primary product, and is acutely dependent on imported products of its processing. Therefore, the outlook for the wheat grain production development is associated with the expansion of production of wheat grain processing products, with its advanced processing and export of products with high added value. The development of advanced grain processing will increase the profitability as of agribusiness, the processing industry in general, as of exporters.

Recently, much attention has been paid to the introduction of raw materials with a low glycemic index into the food industry, among which buckwheat, oat and barley flour occupy a special place. The use of raw materials with a low glycemic index in the formulation of flour confectionery products makes it possible to improve both the organoleptic and physicochemical properties of the product. They also allow to reduce the energy value of such products by reducing the amount of wheat flour, low-calorie margarine, melange and at the same time significantly increase the biological value of the food product. With the aim of adjusting the chemical composition, three recipes for cookies have been developed wheat-oat, wheatbuckwheat and wheat-barley, with the replacement of water in the recipe with an infusion from the collection of herbs “Arfazetin-E”, replacing part of the low-calorie margarine with linseed oil, with the addition of wheat flakes and flaxseed, as well as an aqueous solution of sorbitol and stevioside, apple pectin, iodized salt and flavocene (dihydroquercetin). The introduced components will improve the structural and mechanical properties of the dough, organoleptic and physicochemical indicators of the finished product, and bring the composition closer to the formula for balanced nutrition. The use of unconventional raw materials with a low glycemic index in the food industry makes it possible to enrich the chemical composition of biscuits with dietary fiber, vitamins, and mineral components. From the results of the analysis of the nutritional value, it follows that the finished product contains vitamins B1, B2, β-carotene and E, which can be used for therapeutic and prophylactic nutrition. The use of non-traditional raw materials of vegetable origin in the recipe for cookies leads to an increase in the biological value of the product and a decrease in its calorie content.

The regional meat market is part of the all-Russian meat market and part of the agricultural and food markets. A market forecast is a scientific foresight of the prospects for the development of demand, supply and prices. Its main role is determined by the large volumes of manufacture and consumption of this group, as well as the importance of meat and meat products as the main sources of animal proteins in the human diet. The structure of meat consumption in Russia and in the Kursk region until 2020 was investigated. The consumption of basic food in thousand tons per capita per year was given, the provisions characterizing the meat market of the Kursk region were determined. The conjuncture of the meat market of the Kursk region is characterized by the ratio of supply and demand for meat and meat products, as well as by the level and ratio of prices. A market analysis of the meat market of the Kursk region was carried out, taking into account external factors (level and structure of income, national production, imports, etc.). The supply and demand curves of the meat market were obtained for the last 5 years. The interrelationship of demand for a product and its determinants is reflected by the general demand function and is presented in the form of a multiple regression model. The regressive addiction of the volume of demand was made up using the MathCADProfessional package. The solution to the system of linear equations is presented in matrix form. The vector of estimates of the regressive model was obtained and an additive function was compiled on the basis of this vector. The forecast оf the demand for meat in the Kursk region was obtained using neural networks (NN). The configured network was used for forecasting using the Neural Network Emulator softwares llike magnm, calciumesium, potassiu, zinc, copper, molybdenum, sodium and chlorine, increased.

According to the Federal Law of August 3, 2018 No. 280-FZ organic agriculture is referred to as total economic activity that enables the development of ways, methods and technologies that promote favorable state of the environment and improve human health. The need for this law is dictated by the data of the Research Institute of Nutrition of the Russian Academy of Sciences, which claim that 30-50% of all diseases of Russians arise from the consumption of poor-quality food. 30% of the pollution of the world ecosystem refer to an agricultural sector, which is an obvious need for the greening of agriculture and the production of organic products. Organic products mean environmentally friendly agricultural products, raw materials and food in the production of which the following requirements are met: the use of agrochemicals is prohibited, pesticides and antibiotics, growth stimulants are absent, and hormones are not used in animal fattening. Taking into account Russian legislation, the products of dairy cattle breeding should not indicate the presence of oxytetrocycline, levomycetine, streptomycin, tetracycline, ampicillin, penicillin, grisin, bacitrocin. Natural resistance in cows is reduced as a result of negative factors (stress factors) characterizing the industrial technology for the production of livestock products itself, and negative environmental factors. Currently, the development of dairy cattle breeding and the increase in animal productivity are restrained by the high incidence of diseases of the reproductive organs, among which a significant part are inflammatory diseases of the genitals, in particular endometritis (up to 90% of the total number of calving cows). The use of herbal preparations in folk and traditional veterinary science and medicine makes it relevant to search for new plants for obtaining medicinal raw materials in the treatment and prevention of endometritis. Common thyme is proposed as such. The article shows the results of using common thyme for cows with endometritis as antibiotic replacement therapy, which confirmed by an increase in a number of biochemical blood indicators and the overall health of animals.
