Authors: Li Xiuhan , Rong Ju , Bu Jiaojiao , Sui Yudong , Zhang Yannan , Wei Yan
Published: October 2023

The frontiers of material corrosion research are transitioning from macroscopic corrosion to the micro or even nanoscale. However, nanomaterials contain a large number of simulated atoms, which brings great difficulties to the research of corrosion mechanisms and material development. Therefore, under the framework of lattice dynamics, combined with nano-thermodynamic theory, the electrochemical Butler-Volmer (BV) equation is developed to simplify the investigation of the anodic dissolution behavior of nanomaterials. The results show that the difference between the lattice parameters optimized using the General Utility Lattice Program (GULP) and the Cambridge Sequential Total Energy Package (CASTEP) results is 0.01 Å, and the variation in cohesion and surface energies is only 0.001 eV and 0.005 eV/Å2. Meanwhile, the anodic dissolution rates of Magnesium (Mg) at the (0001), (10一10), and (11一20) crystal planes calculated from the BV model based on lattice dynamics are in agreement with the results derived from first principles. During the active dissolution zone, the corrosion potential increases from − 7.53 V to -5.44 V, and the corrosion current density decreases from 47.48 A/cm2 to 29.97 A/cm2 as the Mg nanoparticles size increases from 1 nm to 6 nm. The improved model quantifies the relationship between surface properties and corrosion behavior through the size effect of nanoparticles, which enriches the way of studying electrochemical properties at the nanoscale.

Authors: Alamuti Masoumeh Motevalli , Khalilian Madjid , Bastanfard Azam
Published: October 2023

High-dimensional data, such as microarray data, are commonly utilized to diagnose diseases. In this type of data, each array corresponds to a gene in the chromosomal makeup. As certain diseases are caused by gene mutations, identifying these genes is crucial for accurate disease classification. Feature selection (FS) is a key approach in pattern recognition and bioinformatics to reduce the number of dimensions in a dataset. However, selecting a subset of features that maintain the original data's characteristics without sacrificing classification accuracy is a challenging task, as it is an NP-hard problem. Meta-heuristic optimization methods have shown promising results in addressing this issue. This paper proposes a feature selection approach that employs the Giza Pyramids algorithm with a deep learning kernel to identify informative genes for cancer patient classification. The method is evaluated using five well-known microarray datasets in the field of cancer diagnosis. The experimental results demonstrate that the proposed method outperforms other classification methods in terms of various evaluation criteria. Specifically, the Giza Pyramids algorithm with a deep learning core successfully selects useful genes for cancer patient classification, leading to improved classification accuracy.

Authors: Sharma Amit , Dubey Nitin
Published: October 2023

This study seeks to investigate the concept of combining coal power, concentrated solar power (CSP), as well as atmospheric pollutant (CO2) capture and storage (CCS) techniques in order to lower the emissions of carbon in electrical networks. Using concentrated solar energy, the study intends to absorb CO2 from the environment and coal-fired power plants and utilise it to grow microalgae in raceway ponds. The paper advocated the generation of microalgae using captured CO2 and included mathematical and experimental studies for carbon capture and sequestration from coal power plants. The study also provided information on the energy incident on the Scheffler dish, the typical steam temperature, the plant's efficiency in capturing carbon, and the total amount of CO2 released over time. The analysis comes to the conclusion that the system has the potential to remove 394200 kg of carbon dioxide annually and that improving the solar concentrator's design and operation can increase both the output and efficiency of the power generation system
Case Report: CYP1A2 Ultra-Rapid Metabolizer in schizophrenia with multiple overdose antipsychotics
Authors: Yang Min , Cao Yudong , Wu Haishan , Zhang Li
Published: October 2023

Background
Liver cytochrome P450 (CYP450) enzymes play an important role in metabolizing antipsychotics (APs) and other drugs. Excessive use of drugs can impair liver function and even other organs, thus causing several adverse effects. In addition, metabolizer types of CYP450 enzymes may influence the therapeutic effects and drug reactions.
Case presentation
In this case, we described a patient with schizophrenia who took overdose of multiple kinds of APs and other herbal preparations together for nearly two years. However, poor treatment effects and minor side effects of APs were presented in this patient. After pharmacogenomic examination, we found this patient was a CYP1A2 ultra-rapid metabolizer.
Conclusions
CYP1A2 ultra-rapid metabolizer may explain part of the poor therapeutic effects and small adverse effects in this case who took multiple kinds of overdose drugs. Many factors may be involved in the rare presentations in this patient.
Method for Calculating the Radiation Pattern of an Antenna Array Based on Magnetic Type Radiators
Authors: Kukharenko Alexander
Published: October 2023

Currently, in order to increase the information capacity of wireless data transmission channels, increasingly higher frequencies are being mastered. However, interest in low-frequency channels has not been lost. Possessing a low information capacity, they have significantly lower propagation losses in free space, thereby providing a greater communication range. Significant difficulties in operating equipment using low-frequency communication channels arise due to the overall dimensions of the receiving and transmitting antenna elements of the electrical type. An alternative solution in this case could be the use of magnetic-type antenna elements, the overall dimensions of which at the same gain value are much smaller. Unfortunately, developing such structures, they require calculation and modeling of their electromagnetic parameters using specialized software packages. The presented algorithm for calculating the radiation pattern of an array consisting of magnetic-type antenna elements makes it possible to calculate the shape of the radiation pattern and the magnetic field strength values in the near zone. The calculations necessary to obtain the result do not require a large amount of computer time and allow you to quickly obtain the necessary results, which significantly reduces the development time of radio engineering devices. The reliability of the results obtained using the algorithm is confirmed by their comparison with well-known ones. However, when implementing and using the algorithm, one should remember the existing limitations and assumptions, some of which can be removed by introducing additional calculation steps and some complication of the calculations.

Published: October 2023

Objectives: To evaluate the impact of dry eye disease (DED) on depression, anxiety, and stress in Chinese doctoral students studying abroad.
Methods: The assessment of DED was conducted through the utilization of the Ocular Surface Disease Index (OSDI), while the evaluation of psychological symptoms relied upon the abbreviated version of the Depression, Anxiety, and Stress Scale (DASS-21) questionnaire.
Results: Of the 185 students, 129 completed the survey, of which 40 (31.0%) were male and 89 (69.0%) were female. The average age was 36.3±7.0 (mean±SD; range, 22–57) years. In the MANOVA, there was a significant impact of DED severity classification on psychological distress (V=0.19, F(9, 375)=2.83, p=0.003). Univariate ANOVAs indicated that DED severity had a significant impact on anxiety F(3, 125)=6.06, p=0.001 and stress F(3, 125)=3.00, p=0.033.
Conclusions: Symptomatic DED was prevalent in Chinese doctoral students studying abroad. The study also revealed a significant association between aging and an elevated risk of DED, along with a noteworthy impact of the severity of dry eye symptoms on the severity of anxiety and stress symptoms.

Authors: Zhou Yaoqi , lang mei , Litfin Thomas , Chen Ke , Zhan Jian
Published: October 2023

The intricate network of RNA-RNA interactions, crucial for orchestrating essential cellular processes like transcriptional and translational regulation, has been unveiling through high-throughput techniques and computational predictions. With the emergence of deep learning methodologies, the question arises: how do these cutting-edge techniques for base-pairing prediction compare to traditional free-energy-based approaches, particularly when applied to the challenging domain of interaction prediction via chain concatenation? In this study, we employ base pairs derived from three-dimensional RNA complex structures as the gold standard benchmark to assess the performance of 22 different methods, including recently developed deep learning models. Our results demonstrate that the deep-learning-based methods, SPOT-RNA and coevolution-information-powered SPOT-RNA2, can be generalized to previously unseen RNA structures and are capable of making accurate zero-shot predictions of RNA-RNA interactions. The finding underscores the potential of deep learning as a robust tool for advancing our understanding of these complex molecular interactions.

Efficient pathogen enrichment and nucleic acid (NA) isolation are critical for accurate and sensitive diagnosis of infectious diseases, especially those with low pathogen levels. Our study introduces a biporous silica nanofilms-embedded sample preparation chip (BSNFs-chip) for pathogen and NA enrichment/isolation. The BSNFs-chip features unique biporous nanostructures comprising large and small pore layers. Computational simulations confirm that these nanostructures enhance the surface area and promote the formation of nanovortex, resulting in improved capture efficiency. Notably, the BSNFs-chip demonstrates a 100-fold lower limit of detection (LOD) compared to conventional methods used for NA detection. Clinical validations using patient samples corroborate the superior sensitivity of the BSNFs-chip when combined with the luminescence resonance energy transfer (LRET) assay. The enhanced sample preparation efficiency of the BSNFs-chip, along with the facile and straightforward synthesis of the biporous nanostructures, offers a promising solution for polymer chain reaction (PCR)-free detection of NAs.

Authors: Zamansky Anna , Feighelstein Marcelo , Luna Stelio , Silva Nuno , Trindade Pedro , Linden Dirk van der , Zamansky Anna
Published: October 2023

This study explores the question whether Artificial Intelligence (AI) can outperform human experts in animal pain recognition using sheep as a case study. It uses a dataset of N=48 sheep undergoing surgery with video recordings taken before (no pain) and after (pain) surgery. Four veterinary experts used two types of pain scoring scales: the sheep facial expression scale (SFPES) and the Unesp-Botucatu composite behavioral scale (USAPS), which is the `golden standard' in sheep pain assessment. The developed AI pipeline based on CLIP encoder significantly outperformed human facial scoring (AUC difference = 0.115, p<0.001) when having access to the same visual information (front and lateral face images). It further effectively equaled human USAPS behavioral scoring (AUC difference= 0.027, p=0.163), but the small improvement was not statistically significant.

Out-of-equilibrium behavior in CuCl
Authors: Pimentel Dyvison Pedreira
Published: October 2023

The results shown here provide some information about electric field-induced metallic state in CuCl. It is notable that in addition to the applied electric field inducing the transition from a high-resistance state to a low-resistance state, the electric field can drive the sample back to the high-resistance state. This means that the metallic state of CuCl is out of equilibrium. In addition, the contribution of the antiferromagnetic fluctuations of Clinoatacamite to the magnetotransport properties of oxidized CuCl is evident.
Synthesis, homopolymerization and properties of p-aminopyridine methacrylate
Authors: Vakhabova V. E. , Guliev K. G.
Published: October 2023

For the first time, p-aminopyridine methacrylate was synthesized by a reaction between p-aminopyridine and methacryloyl chloride. IR and NMR spectroscopy сonfirmed the obtained compound structure. Radical homopolymerization of synthesized p-aminopyridine methacrylate was carried out either in bulk or in benzene solution (initiator – AIBN). The study of radical polymerization regularities of p-aminopyridine methacrylate discovered no side reactions and induction period of the reported process under the created conditions with a maximum yield of 92%. It was found that p-aminopyridine methacrylate is a more reactive monomer in radical polymerization as compared to methyl methacrylate. The structure of the obtained monomer and polymer was investigated by IR and NMR spectroscopy. Based on these data, the polymerization proceeds by a double bond, with substituents in the side macro chain remaining unreacted. The study of the synthesized monomer polymerization in the bulk indicated the presence of the gel effect. The autoacceleration begins at ~25% monomer conversion during the polymerization process, which agrees with the literature data. It was discovered that the polymerization of p-aminopyridine methacrylate proceeds at a rate higher than that of methyl methacrylate. This observation is likely to be connected with the substituent contribution to the electronic state of the entire monomer molecule. Hence, the electron density of the vinyl group changes and the growing radical becomes stabilized with the substituent –M-effect. The polymer synthesized possesses high antimicrobial properties.

Published: October 2023

In this work, we investigate the catalytic properties and immobilization of enzyme preparations containing lipase of haloalkalotolerant bacteria Pseudomonas peli and Bacillus aequororis. Lipase was isolated from the P. peli 3-T and B. aequororis 5-DB followed by its immobilization on either carboxymethylcellulose, activated chitosan or fodder yeast. The pH-dependence of native enzyme activity and thermostability, as well as the residual activity upon immobilization and drying of immobilized product, were determined. The lipase activity from both sources enhances with increasing alkalinity of the reaction medium. Specifically, P. peli 3-T lipase exhibited no activity in an acidic medium, and B. aequororis 5-DB lipase exhibited around 20% of maximum activity at a pH value of 6–7. The isolated lipase has a rather high thermostability; thus, P. peli 3-T lipase fully retains its initial activity upon heating to 60°C and 70°C for 1 h. Moreover, 15 min exposure to temperatures of 80°C and 90°C leads to an activity decrease of 73% and 83%, respectively. Activated chitosan and fodder yeast are the most promising of the studied excipients for enzyme immobilization. Drying of the immobilized lipase product on the activated chitosan showed retention of 3% and 46% of the native enzyme activity derived from P. peli 3-T and B. aequororis 5-DB, respectively. In the case of fodder yeast, these values were 2% and 64%, respectively.

Time management (TM) is a crucial academic ability, especially as schools transition from conventional to virtual instruction delivery during the coronavirus disease 2019 (COVID-19) pandemic. The aim of the study was to identify the variables affecting medical science undergraduate students in Iran during the COVID-19 pandemic. This web-based cross-sectional study was conducted in 2021. Participants included medical students and students pursuing a bachelor’s degree in medical sciences. They were conveniently selected from medical universities across Iran. A demographic questionnaire and the Trueman and Hartley Time Management Questionnaire were used as study instruments. Telegram and WhatsApp were used for data collection and sampling. The SPSS program (version 22.0) and multiple linear regression (MLR) analysis were used to analyse the data. In total, 1,183 students completed the questionnaires in their entirety. The mean of their age was 22.08±3.15 years and the majority of them were female (62.04%). The mean TM score was 45.19±8.3 (with a range of 14–70), and gender, grade point average (GPA), daily study time, daily internet use time, work status, and kind of university were the significant predictors of TM ability (p < 0.05). Iranian students have a moderate level of TM skill, and their work status, GPA, daily study time, daily Internet usage, and type of university are the main predictors of their TM. The shift from traditional to virtual learning during the COVID-19 pandemic highlights the importance of equipping medical students with necessary TM skills.
Quantized Berry winding from an emergent $\mathcal{PT}$ symmetry
Authors: Louvet Thibaud , Delplace Pierre , Goerbig Mark-Oliver , Carpentier David
Published: October 2023

Linear crossings of energy bands occur in a wide variety of materials. In this paper we address the question of the quantization of the Berry winding characterizing the topology of these crossings in dimension D=2D=2. Based on the historical example of 22-bands crossing occuring in graphene, we propose to relate these Berry windings to the topological Chern number within a D=3D=3 dimensional extension of these crossings. This dimensional embedding is obtained through a choice of a gap-opening potential. We show that the presence of an (emergent) \mathcal{PT}𝒫𝒯 symmetry, local in momentum and antiunitary, allows the quantization of the Berry windings as multiples of \piπ. We illustrate this quantization mechanism on a variety of three-band crossings.
Complexity of frustration: A new source of non-local non-stabilizerness

Published: October 2023

We advance the characterization of complexity in quantum many-body systems by examining WW-states embedded in a spin chain. Such states show an amount of non-stabilizerness or “magic”, measured as the Stabilizer Rényi Entropy, that grows logarithmically with the number of qubits/spins. We focus on systems whose Hamiltonian admits a classical point with extensive degeneracy. Near these points, a Clifford circuit can convert the ground state into a WW-state, while in the rest of the phase to which the classical point belongs, it is dressed with local quantum correlations. Topological frustrated quantum spin-chains host phases with the desired phenomenology, and we show that their ground state’s Stabilizer Rényi Entropy is the sum of that of the WW-states plus an extensive local contribution. Our work reveals that WW-states/frustrated ground states display a non-local degree of complexity that can be harvested as a quantum resource and has no counterpart in GHZ states/non-frustrated systems.

Published: October 2023

Corymbia citriodora has the potential to be used in the expansion of the forestry sector in Brazil, as it presents greater tolerance to abiotic stresses than other commonly cultivated species. The plants are exposed to several stress events throughout their cycle that can compromise their growth and development. This study aimed to evaluate physiological, biochemical, and growth characteristics in C. citriodora plants grown under different irrigation regimes at different ages. Plants of C. citriodora grown in pots were submitted to five irrigation regimes (20, 35, 50, 65, and 80% of the maximum soil water retention capacity) for 105 days in a greenhouse. Plant growth, gas exchange, leaf water potential, chlorophyll, carotenoids, and proline contents, and lipid peroxidation by MDA content were evaluated at the end of this period. More restrictive irrigation regimes reduced seedling growth. Water availability affected physiological, biochemical, and morphological parameters. Water stress associated with plant growth increased stress levels

The vigor tests are important tools used in the internal quality control by the seed companies. The accelerated aging test is a sensitive method for assessing the vigor of seed lots, as well as for estimating their storage potential. However, for coffee seeds there is little information about its use and efficiency.The objective of this study was to investigate methods of the accelerated aging test suitable for Coffea arabica L. seeds. Two studies were carried out. In the first, different temperatures (42°C, 44°C, and 46°C) and exposure times (0, 24, 48, 72, 96, 120, 144, 168, and 192 h) were investigated for the accelerated aging test. In the second, the best combinations of temperatures and exposure times were tested on coffee seeds from five different cultivars at temperatures of 44 and 46 ºC at times of 24, 48, 72, and 96 h of incubation. After each aging period, the water content of the seeds was determined, and physiological quality was evaluated by the germination test. The temperature of 42°C leads to slow deterioration of the seeds and is not recommended for evaluation of Coffea arabica L. seed vigor at the exposure times from 24 to 192 h tested here. The accelerated aging test, carried out at a temperature of 44ºC for 72 hours or at 46ºC for 48 hours, allows the Coffea arabica seed lots to be separated into different vigor levels

Published: October 2023

The common bean is one of the most produced and consumed species in Brazil, but the productivity of the crop is still low. The use of new technologies has increased the performance of the production system and allowed greater flexibility in the management of the production system. The use of super-early cultivars combined with co-inoculation with bacteria has become a promising alternative for the production system. Thus, the objective of this work was to evaluate the agronomic performance of the super-early common bean cultivar BRS FC104 in response to co-inoculation of Rhizobium tropici and Azospirillum brasiliense. Three field experiments were conducted in Santo Antônio de Goiás (water 2018/19 and winter 2019) and in Abadia de Goiás (winter 2019). A randomized block design was used in a 2 x 3 factorial scheme for all experiments, being two common bean cultivars (BRS Notável and BRS FC104 cultivars) and three nitrogen sources (co-inoculation with R. tropici + A. brasilense; nitrogen fertilization and untreated control). The co-inoculation with Rhizobium tropici and Azospirillum brasilense resulted in grain yield equal to that of the nitrogen treatment. The super-early cultivar BRS FC104 showed equivalent productivity as the normal cycle cultivar BRS Notável. Considering that N-fertilizers are a threat to the environment and intensification of sustainable production is a pressing need, the cultivation of the super-early cultivar BRS FC104 under co-inoculation is a recommendation for the sustainable production of the common bean.

Albizia polycephala (Benth) Killip, popularly known as angico-branco, belongs to the Fabaceae - Mimosoideae family, is a pioneer species used for environmental restoration, ornamentation and urban afforestation. Biometric characterization is an important tool to provide information on the type of germination, in addition to describing the morphology of the seed, it stimulates studies inherent to taxonomy, ecology and seed technology. For the production of seedlings, the most used form of propagation of this species is through seeds. Therefore, with the establishment of protocols to overcome dormancy of forest species, the producer will be able to choose the most efficient method and also the one that best adapts to his reality, both commercial and technological, providing an increase in the number of species destined to compose the models for the recovery of degraded areas to be implemented. Based on this, the objective of this work was to carry out the biometric characterization of the seeds, describe the post-seminal stages and verify the best way to promote the germination of A. polycephala using pre-germination treatments to overcome dormancy. The work was carried out at the Laboratory of Phytotechnics of the Campus of Engineering and Agricultural Sciences (CECA) of the Federal University of Alagoas (UFAL). The differentiation and development of A. polycephala seedlings was measured. In the dormancy breaking trial, the following treatments were used: i) control (intact seeds); (ii) chemical scarification by immersing the seeds in sulfuric acid for 5 min, followed by washing in running water; iii) cut (cut) on the side opposite the micropyle; iv) immersion in hot water (80°C) and cooling for 24 h; v) immersion in distilled water (room temperature) for 24 h; and vi) immersion in distilled water (room temperature) for 48 h. The seeds were incubated in a germination chamber at a constant temperature of 30°C. The design used was completely randomized, with 4 replications of 25 seeds per treatment, and the means were compared by Tukey's test at 5% probability. At the time of installation of the experiment, the seeds had a water content of 12.4%, with an average of 10.3 mm in length, 7.42 mm in width and 2.46 mm in thickness. Germination is epigeous and seedlings are phanerocotyledon. The physical rupture of the seed coat from the bud treatment contributed to the increase in permeability to water and gases, thus benefiting the germination process. Thus, topping can be recommended to overcome A. polycephala seed dormancy.

Published: October 2023

This study aimed to (i) establish the diagnosis and recommendation of integrated system (DRIS) norms for the evaluation of nutrient status in pineapple plants and (ii) validate the reliability of DRIS norms. Eighty-six leaf samples at +1 (E leaf) and +3 (D leaf) positions were collected from 86 pineapple fields cultivated in acid sulfate soils at the leaf development stage. Results indicated that DRIS norms established for pineapple included 22 and 30 pairs of nutrient ratios at E and D leaf positions, respectively. The validation for the reliability showed that founded DRIS norms were reliable and suitable for assessing the nutrients status of pineapple. Based on the fertilizer omission plot technique, DRIS indices of N, Ca, and Mg in the treatments without N, Ca, or Mg fertilizer, respectively, were less excessive than those in the treatment with full NPKCaMg fertilization at both leaf positions, meaning that the DRIS norm is reliable. Both leaf positions can be used to diagnose N, K, Ca, and Mg nutrients status

Safflower has recently been introduced to Brazil. This plant has attracted this view due to its properties and capacity to supply oil that can potentially be used both in the manufacture of biofuels and in the food industry. In order to contribute with studies for the viability of this crop in the country, which are still lacking in the management of seeding, the study aimed to assess the mechanization of seeding a safflower genotype in two seeding depths (4.5 and 6.5 cm) and three levels of loads applied to the wheels (117.7, 156.9, and 196.1N) in the emergence, growth, and grain yield. The experimental design of randomized complete block design arranged in factorial 2 × 3, with four replications. Seeding depth and loads on press wheels did not affect the emergence rate of safflower. The root length, plant height, stem diameter, and dry mass of the plant at 30 DAE were benefited by seeding in depth of 4.5 cm in relation to the depth of 6.5 cm. Higher grain yield was observed for loads of 196.1 N compared to the pressure of 117.7 N, with values of 725 and 443 kg ha–1, respectively. Grain yield was 61% higher when seeding at a depth of 4.5 cm. Thus, the adjustment of the compactor wheels can influence in the safflower seeding process

Cassava is extensively cultivated in low fertility sandy soils in the Northeast Thailand. Low yield and economic return of cassava grown in this area is partly due to deficiency of micronutrients especially zinc (Zn). The objective of this study was to investigate the effects of foliar spray of Zn on growth, yield, quality and economic return of the cassava variety Kasetsart 50. Five treatments consisted of unfertilized control (T1), recommended fertilizer (formula (formula 15-15-15 at the rate of 313 kg ha-1) (T2), recommended fertilizer plus foliar spray of Zn at the rate of 6.25 kg ha-1 (2% Zn) (T3), recommended fertilizer plus foliar spray of Zn at the rate of 12.50 kg ha-1 (4% Zn) (T4) and recommended fertilizer plus foliar spray of Zn at the rate of 18.75 kg ha-1 (6% Zn) (T5). The treatments were assigned in a randomized complete block design with three replications. The crop was planted in a Korat soil series (loamy sand soil) under rainfed conditions. Data were recorded for soil chemical properties and plant growth parameters at 11 months after planting. The recommended fertilizer plus foliar spray of 2% Zn (T3) resulted in the highest fresh root yield (26.0 t ha-1), starch content (27.83%), and economic return over the fertilizer cost (960.0 USD ha-1), and the increases in fresh root yield, starch content and economic return over the fertilizer cost compared to T1 were 100, 54 and 69%, respectively. The results suggested that foliar spray of 2% Zn together with chemical fertilizer was effective in overcoming Zn deficiency in the loamy sand soils for cassava variety Kasetsart 50 production

The identification of species that promote phytoremediation of herbicides is of great relevance to reduce the impact of these products on the environment. This study aims to evaluate the efficiency of plant species in the phytoremediation of the indaziflam herbicide. The phytoremediation potential for indaziflam of 15 species of green manure was evaluated at different sowing times of the Phaseolus vulgaris (bioindicator), after the herbicide application. P. vulgaris was sown after the removal of the aerial part of the selected green manure. The experiment was conducted in a greenhouse, and each green manure species was evaluated separately in a completely randomized design, with four replications. The treatments were arranged in a 3 x 5 factorial layout, consisting of three doses of indaziflam (0, 75 and 100g a.i. ha-¹) and five sowing times (5, 30, 60, 90 and 120 days after the herbicide application). According to the phytotoxicity and biometric evaluations of green manure, the potential species for the phytoremediation of the indaziflam were selected. The results showed that, apart from the species Lupinus albus, Canavalis ensiformis and Mucuna cinerea, the other green manure evaluated were highly susceptible to the herbicide indaziflam. However, although these potential species presented less control by indaziflam, none of them were effective in their soil phytoremediation. The bioindicator showed high phytotoxicity and reduction of dry mass due to the herbicide, regardless of the green manure sowing season on both doses of indaziflam. As a phytoremediator, none of the green manure species were effective for indaziflam even after 120 days of the herbicide application.

The review is devoted to the foundation and development of the scientific school of S. V. Vallander at the Leningrad (now St Petersburg) State University. The achievements of the scientific school in the development of the kinetic theory methods for modeling nonequilibrium flows, construction of rigorous self-consistent mathematical models of varying complexity for strong and weak deviations from equilibrium, and the use of the developed models in challenging problems of modern aerodynamics are discussed. Particular attention is paid to the study of non-equilibrium kinetics and transport processes in carbon dioxide, identification of key relaxation mechanisms of polyatomic molecules, derivation of physically based reduced hybrid models, and optimization of non-equilibrium flow numerical simulations using modern machine learning methods. Correct description of electronic excitation in the kinetics and transport processes, models of local equilibrium gas flows with multiple ionization, and features of modeling bulk viscosity in polyatomic gases are discussed.
On probabilities of large deviations of combinatorial sums of independent random variables satisfying Linnik’s condition
Authors:   St. Petersburg State University, Frolov Аndrei N.
Published: October 2023

We derive new results on asymptotic behaviour for probabilities of large deviations of combinatorial sums of independent random variables satisfying Linnik’s condition. We find zones in which these probabilities are equivalent to the tail of the standard normal law. The author earlier obtained such results under Bernstein’s condition. The truncations method is applied in proofs of results.
Publicism of F.M.Dostoevsky and A.I. Solzhenitsyn: From socialism to the “Russian idea”

The purpose of the article is to describe the socio-political and philosophical views of Dostoevsky and Solzhenitsyn on socialism and the “Russian idea”. The empirical basis of the study is publications from Dostoevsky’s “Diary of the Writer”, as well as articles, interviews, speeches at press conferences by Solzhenitsyn. The study is divided into several parts: 1) analysis of thе views of Dostoevsky and Solzhenitsyn’s youth; 2) socialism as the antithesis of Christianity; 3) transformation of socialist ideas; 4) understanding of the “Russian idea”. Dostoevsky’s “Diary of the Writer presented not a rejection of socialist ideas, but a critique of the European version of socialism and an understanding of “Russian socialism”. This becomes the basis for the formulation of the “Russian idea”, associated for Dostoevsky with the conviction that the Russian nation must bring true Orthodoxy to other nations. The novelty of research is that it presents a comparative analysis of Dostoevsky’s and Solzhenitsyn’s ideas about socialism, messianism, the “Russian idea”, and the fate of Russian people. These ideas are reflected in the authors’ publicism related to the issues of Russian pochvennichesvo. Solzhenitsyn argues about the fate of the people and its task. However, the “Russian idea” becomes “the preservation of people” and the rejection of global objectives. At the same time, these calls and Christian ideals are paradoxically combined in the work of Solzhenitsyn with a love for the revolution and the demand to fight communism in the USSR.

Most of the studies of Sumarokov’s work as a journalist regard the writer as a satirist. In contrast, this article suggests a different perspective on the problem of Sumarokov’s literary legacy. Based on the analysis of the narrative potential of the June issue of “Hardworking Bee”, the study proposes to look at the public activity of Sumarokov the publisher as a special communicative strategy. The journal began to claim the formation of a public sphere, offering its conception of personal and social identity. Sumarokov’s journal became an entirely new institution with its audience, along with literary and scientific societies, secular salons, public theatres, and Masonic lodges. The article contains historical commentary and interpretation of the historical-literary and personal contexts of June 1759. The aim of the article is to study the journal metatext of the June issue of “Hardworking Bee”, to examine the problematics and poetics of the texts published in it. The article uses methods of literary studies: historical-typological, cultural-historical, biographical and comparative-historical. The study demonstrates that Sumarokov’s metatextual narrative realized a new model of cyclization for Russian literature. At the lowest, ordinary level, the reader could remain a profane, and at the highest level the reader the reader is turned into a hermetic wise man. We can conclude that Sumarokov’s journal “Hardworking Bee” stimulated the creation of most monthly editions not only in the Russian 18th century. The article emphasizes the importance of Sumarokov’s experience as a publisher and editor for the evaluation of his creativity in general.

The article describes an experiment about training a part-of-speech tagger using artificial neural networks on the St. Petersburg Corpus of Hagiographic Texts (SKAT), which is being developed at the Department of Mathematical Linguistics of St. Petersburg State University. The corpus includes the texts of 23 manuscripts dating from the 15th–18th centuries with about 190,000 words usages, four of which were labelled manually. The bi-LSTM, distilled RuBERTtiny2 and RuBERT models were used to train a POS tagger. All of them were trained on modern Russian corpora and further fine-tuned to label Old Russian texts using a technique called language transfer. To fine-tune transformer-based language models it was necessary to tokenize the texts using byte pair encoding and map tokens from the original Russian-language tokenizer to the new one based on indices. Then the model was fine-tuned for the token classification task. To fine-tune the model, a tagged subcorpus of three hagiographical texts was used, which included 35,603 tokens and 2,885 sentences. The experiment took into account only the tags of the parts of speech, the classification included seventeen tags, thirteen of which corresponded to parts of speech, and the remaining four marked punctuation marks. To evaluate the quality of the model, the standard metrics F1 and Accuracy were used. According to automatic evaluation metrics, the RuBERT model showed the best result. Most of the errors were related to incorrect generalization of linear position patterns or to the similarity of word forms in both the extreme left and extreme right positions.
