Numerical Reconstruction of Heat Source on a Semi-Infinite Rod
Authors: Deng Zui-Cha , Yang Xin-Rui , Yang Liu
Published: June 2024

Inverse heat conduction on an unbounded domain has always been the focus and difficulty in engineering and mechanical fields. In this paper, we consider the inverse problem of identifying the heat source by using the terminal measured temperature data. Being different from other ordinary heat conduction problems, our mathematical model is defined in a semi-infinite region, which may lead to many numerical methods that cannot be used directly. Based on the artificial boundary method, we first introduce the truncated boundary and derive the exact boundary conditions on it. Then we use the finite difference method to establish an approximate difference scheme for the forward problem. For the inverse problem, we design the Landweber and conjugate gradient iterative algorithm and do numerical experiments. Numerical results verify the correctness and effectiveness of our algorithm.

Published: June 2024

SYNOPSIS: This editorial critically evaluates how hip-related pain is currently managed, highlighting the limitations of traditional biomedical interventions alone in restoring optimal function and well-being. Psychological factors are key determinants of outcomes after surgical and nonsurgical treatment. We highlight the need for a holistic, patient-centered approach in evaluating and treating hip-related pain. Shifting to a holistic, patient-centered approach can improve treatment outcomes and reduce patient suffering. We guide readers to the impact of psychological factors on treatment outcomes, provide clinical considerations for how clinicians might approach psychologically informed practice, and outline future research directions.

In the southern regions of the Russian Federation, there has been a sharp decline in livestock production due to its low profitability. As a result, many farmers lack organic fertilizers, which are difficult to replace fully with mineral fertilizers. In addition, mineral salts cause negative processes (peptization, coagulation) in the soil profile, which worsen the physical and physical and chemical properties of the soil and its fertility in general. However, a good source of soil organic matter is not only livestock waste, but also plant residues or so-called green fertilizers. In this regard, in 2021–2022, we studied the effect of ammonium nitrate on the yield of green mass of brown mustard (Brassica juncea L.) variety Yunona on leached black soil of the Western Ciscaucasia on the fields of V.S. Pustovoit All-Russian Research Institute of Oil Crops (Krasnodar, vil. Oktyabrsky). The purpose of the research was to assess fertilizing value of ammonium nitrate (ability to return the elements of mineral nutrition at full green manuring of plants). It was found that the highest efficiency of the nitrogen fertilizer application is achieved with a single application of N30 at the seedling stage of mustard. With this specific method of N30 application, more green mass and dry biomass are incorporated into the soil, by 10.6 t/ha and 3.34 t/ha, respectively, compared to the control. At the same time, the yield of macroelements is also higher: nitrogen – by 64.3 kg/ha, phosphorus – by 14.3 kg/ha, potassium – by 155.3 kg/ha, and the estimated amount of newly formed humus increases by 0.7 t/ha comparing to control.

The purpose of the research was to evaluate oil flax (Linum usitatissimum L.) varieties originating from different geographical and ecological regions based on their yield formation and biological properties in conditions of the Eastern steppe zone of Mongolia. Mathematical and statistical analyses were performed on yield and its component parameters. According to the study results of 2019–2022, early maturing oil flax varieties such as Flanders and Norine-67 demonstrated a seed yield of 2.02–2.22 t/ha and oil content of seeds 37.0–38.2%. Their seed yield was higher by 0.97–1.17 t/ha compared to the control and other varieties. The late maturing variety Blatall demonstrated a seed yield of 1.36 t/ha and 40.7% oil content of seeds, with a seed yield higher by 0.01–0.54 t/ha compared to the control and other varieties. Due to our results, early maturing oil flax varieties can be cultivated in the soil and climatic conditions of crop production zones in Mongolia, achieving a high yield (1.05–2.22 t/ha).

The study aimed to characterize the ecological aftermath of the impact of gasoline on biological objects. On today, oil and products from it remain one of the most common pollutants. The novelty and relevance of the study are determined by the minimum database of cytogenetic changes after impact of gasoline on biota. The registration of such consequences, as a rule, negative ones, dictates the need to develop directions and methods for the reclamation of contaminated areas. An experimental study using a model plant object – watercress (Lepidium sativum L.) revealed the aftermath of gasoline impact. This object made it possible to identify a complex of changes determined by the gasoline. The experiment studied the effect of AI-95 gasoline in concentrations of 3, 5, 10% (water solution). For cytogenetic analysis, temporary compressed micro preparations of root sections stained with acetoorcein were examined. The anaphase method was used to account the chromosomal abnormalities. Gasoline can also be characterized as a mutagen. The level of mutations (bridges, fragments, micronucleus) under the impact of gasoline at a concentration of 5% is 35 times higher than in the control. Multiple violations were registered only as a result of impact by the investigated pollutant, which determines a high increase in the frequency of micronucleus. The proportion of aberrant anaphases in the total number of anaphases in the control was 1,2%, in the experimental variants it increased to 42,0, 68,4 and 79,6% under the impact of gasoline at concentrations of 3, 5 and 10%. Mitotoxic, as well as cytotoxic activity, was recorded. It is shown in a decrease in the mitotic index and a change in the ratio of mitotic phases. In the experimental variants, the frequency of cells in anaphase is decreased and the proportion of cells at the prophase stage is increased. That may be due to increase repair systems operating time. New experimental data on the genotoxicity of gasoline replenish the information database on the negative consequences of the impact of gasoline on plant objects.

Based on the study of the physiological and biochemical characteristics of Heracleum sosnowskyi buds we identified functional adaptations during the preparation of plants for overwintering. The freezing point of water in the buds tissues was –12 оC in October, while maintaining high water content (more than 80%). Buds has a relatively high efficiency of respiration at low positive temperatures (2–5 оC), which favors morphogenesis processes in the shoot vegetative cone in autumn. During the preparation for overwintering the buds accumulated osmoregulators – soluble sugars, free amino acids, including proline. A relatively high level of cytokinin growth hormones was found in the buds tissues. This contributes to morphogenesis processes and increases plant cold tolerance. We found that in December the abscisic acid (a growth inhibitor and resting hormone) content increases and the level of cytokinins decrease. Heracleum sosnowskyi formed buds differing in the photosynthetic pigments content. Buds with green scale leaves accumulated the greatest amount of chlorophylls and carotenoids, while those with red-brown and yellow ones accumulated the least. The carotenoids accumulation in the green buds tissues protects the formed photosynthetic apparatus at low positive temperatures in autumn. The results on the functional state of H. sosnowskyi terminal buds in natural populations indicate the absence of deep dormancy in plants, and morphogenesis processes in meristems tissues are limited by winter temperatures.

By-products of animal husbandry (BPAH) such as manure, manure effluents (ME) are widely used as organic fertilizers. The main disadvantage of the appropriate fertilizers is the high content of microorganisms (MO) untypical to uncontaminated natural environments, including pathogenic ones. Currently used natural methods of BPAH neutralization can significantly reduce the risks of transferring pathogenic and opportunistic MO into fertilized soil, but do not completely exclude them. The study examined the effects of long-term (more than 7 years) introduction of a neutralized liquid fraction (LF) of pork ME and cattle ME on the chemical composition and sanitary and hygienic condition of the soil of arable fields and wooded areas located at 500 m from the boundaries of the fields. Prolonged application of LF led to an increase in the content of organic matter, mobile phosphorus, potassium and sulfur, an increase in the amount of absorbed bases, a decrease in metabolic acidity in arable land compared with adjacent forest areas. However the sanitary condition of both arable land and adjacent territories deteriorated significantly. A significant increase in the total microbial number (TMN) was revealed in all soil samples in comparison to the normative indicators. Particularly high values of TMN were found in soil fertilized with cattle manure. The corresponding soil was characterized by the highest content of organic matter and neutral reactions of the environment, which provided favorable conditions for the active development of saprophytic microbiota. Fresh faecal contamination was detected in all selected soil samples. Soils are characterized as highly polluted. According to the indicators of the index Escherichia coli, Enterococcus and Clostridium perfringens, the soils of all studied sites are moderately dangerous. Higher values of the corresponding indices were found in arable land fertilized by the LF of pork farms and in the territories adjacent to arable land. In the course of sanitary and bacteriological studies, eggs of helminthes were not found in the soil.

This study focused on analyzing the effect of the increase in single-person households and the corresponding increase in the number of people eating alone in the food service industry. With many restaurants still passive in providing single-person dining spaces, this study attempted to contribute to the strategic improvement of the food service industry by empirically examining the relationship between perceived territoriality, perceived value, satisfaction, and intention to revisit among the people eating alone. Research data were collected through an online survey of individuals with experience of eating alone nationwide, and a total of 254 valid responses were used for analysis. Specifically, the structural equation modeling was conducted through the PLS program. The primary findings derived from testing the theoretical model are as follows: First, the perceived territoriality of the people eating alone positively influences both perceived value and satisfaction, while it does not have a direct and significant effect on the intention to revisit. Second, perceived value has a strong effect on satisfaction and intention to revisit. Third, satisfaction has a direct and positive effect on the intention to revisit. This study contributed to developing strategies for the food service industry to increase profitability by understanding the characteristics and needs of the “Honbab” people and seeking ways to respond to them.

This study aims to enhance the innovative behavior of hotel food and beverage department employees, who are emotional laborers, and to understand the relationship between employees' organizational adaptation and innovative behavior by exploring the application of managers' empathetic leadership in food and beverage departments. The empirical results are as follows. First, the manager's empathetic leadership was found to significantly and positively affect organizational adaptation. Second, empathetic leadership was found to have a significant and positive effect on the innovative behavior of hotel members. Lastly, organizational adaptation was found to have a significant and positive effect on innovative behavior. These findings imply that it is necessary to have the empathetic leadership of a mature leader who embraces the emotions of the members, fosters mutual empathy, and respects each individual, rather than relying on traditional leadership that merely directs the department in order to enhance organizational adaptation and innovative behavior among hotel members through the empathetic leadership of the hotel F&B department manager.

Published: June 2024

Organic semiconductors (OSCs) with π-electron skeletons (π-cores) have attracted much attention. The creation of more innovative new molecules with high carrier mobility requires the strategic molecular design. One of the most important properties affecting the carrier mobility of π-conjugated OSCs is the molecular arrangement, especially the two-dimensional (2D) molecular packing of the π-cores which exhibit 1D or 2D carrier conductivity as follows: π-stacking, herringbone (HB) packing, and brickwork (BW). Since two molecular packing structures, HB and BW, have not been predicted theoretically, chemists have typically designed new OSC molecules based on their previous knowledge so far. Therefore, the use of computational science and informatics science is eagerly needed to strategically design an OSC molecule with unprecedented properties and functions. In this study, we introduce machine learning method to determine whether an OSC forms 2D HB or BW molecular packing with a high accuracy. We further present the computational method to predict the crystal structure of an OSC only from its chemical structure using molecular mechanics calculation and molecular dynamics simulation coupled with our proposed machine learning model to classify the type of 2D molecular packing. The combination of molecular simulations with the machine learning model has the potential to predict the crystal structure of organic molecules.

Antibody-drug conjugates (ADCs) represent a novel class of immunoconjugates with growing therapeutic relevance since they combine the efficacy of cytotoxic drugs with the specificity of antibodies. However, by design, ADCs introduce structural features to the mAb scaffold that complicate their analysis. Payload attachment to cysteine or lysine residues can often result in product heterogeneity regarding both the number of attached drug molecules and their conjugation site, necessitating the use of state-of-the-art MS instrumentation to elucidate their complexity. In middle-down mass spectrometry (MD MS), the gas-phase sequencing of ~25 kDa ADC subunits with dif-ferent ion activation techniques generally produces rich fragmentation mass spectra; however, spectral congestion can cause some fragment ions to go undetected, includ-ing those that can pinpoint the exact location of payload conjugation sites. Proton transfer charge reduction (PTCR) can substantially simplify fragment ion spectra, thereby unveiling the presence of product ions whose signals were previously sup-pressed. Herein, we present an MD MS strategy relying on the use of PTCR to investi-gate a cysteine-based ADC mimic with a variable drug-to-antibody ratio, targeting the unambiguous localization of payload conjugation sites. Unlike traditional tandem MS experiments (MS2), which could not provide a full map of conjugation sites, a single PTCR-based experiment (MS3) proved to be sufficient to achieve this goal across all variably modified ADC subunits, including isomeric ones. Combining the results ob-tained from orthogonal ion activation techniques followed by PTCR further strength-ened the confidence in assignments.

This includes an array of candidates such as graphene, carbon nanotubes, carbon nanofibers, boron carbonitride, g-C3N4, mesoporous carbon, ordered mesoporous carbon, and oxygen-enriched porous carbon. The review delves into diverse synthetic methodologies, encompassing chemical vapor deposition, thermal annealing, hydrothermal, microwave routes, and arc discharge techniques for each of these carbon-based materials. Furthermore, an in-depth exploration of the underlying electrochemical mechanisms governing supercapacitive performance is provided. Notably, the synthesis and energy storage proficiency of heteroatom-enriched materials like g-C3N4 and BCN are meticulously scrutinized. The influence of heteroatom doping on crucial characteristics like wettability, and porosity is deeply examined, boosted by compelling empirical substantiation. Adding intrigue, the merits, and drawbacks inherent to each synthetic approach are thoughtfully presented systematically. As a result, this article stands as a highly valuable resource, offering substantial support and insightful information tailored to young researchers. By furnishing a panoramic survey of diverse synthetic avenues and an in-depth analysis of supercapacitive performances across distinct classes of heteroatom-doped/enriched carbon materials, we aspire for this work to become an indispensable reference.
Bayesian Illumination: Inference and Quality-Diversity Accelerate Generative Molecular Models
Authors: Verhellen Jonas
Published: June 2024

In recent years, there have been considerable academic and industrial research efforts to develop novel generative models for high-performing, small molecules. Traditional, rules-based algorithms such as genetic algorithms [Jensen, Chem. Sci., 2019, 12, 3567-3572] have, however, been shown to rival deep learning approaches in terms of both efficiency and potency. In previous work, we showed that the addition of a quality-diversity archive to a genetic algorithm resolves stagnation issues and substantially increases search efficiency [Verhellen, Chem. Sci., 2020, 42, 11485-11491]. In this work, we expand on these insights and leverage the availability of bespoke kernels for small molecules [Griffiths, Adv. Neural. Inf. Process. Syst., 2024, 36] to integrate Bayesian optimisation into the quality-diversity process. This novel generative model, which we call Bayesian Illumination, produces a larger diversity of high-performing molecules than standard quality-diversity optimisation methods. In addition, we show that Bayesian Illumination further improves search efficiency com- pared to previous generative models for small molecules, including deep learning approaches, genetic algorithms, and standard quality-diversity methods.

In the work, protonated poly(heptazine imide) (H-PHI) was obtained by adding acid to the suspension of potassium poly(heptazine imide) (K-PHI) in ethanol. It was established that the obtained H-PHI demonstrates very high photocatalytic activity in the reaction of hydrogen formation from ethanol in the presence of Pt nanoparticles under visible light irradiation in comparison with K-PHI. This enhancement can be attributed to improved efficiency of photogenerated charges transfer to the photocatalyst's surface where redox processes occur. Various factors influencing the system's activity were evaluated. Notably, it was discovered that the conditions of acid introduction into the system can significantly affect the size of Pt (co-catalyst metal) deposition on the H-PHI surface, thereby enhancing the photocatalytic system stability in producing molecular hydrogen. It was established that the system can operate efficiently in the presence of air without additional components on the photocatalyst surface to block air access. Under optimal conditions, the Apparent Quantum Yield (AQY) of molecular hydrogen production at 410 nm is around 73%, the highest reported value for carbon nitride materials to date. The addition of acid not only increases activity of the reduction part of system but also leads to formation of a value-added product from ethanol - 1,1-diethoxyethane (acetal) with high selectivity.

Operating room nurses are at risk of burnout. They face many stressors, such as the workload that must be finished. Using coping strategies that are adaptive to the situation will allow nurses to cope with their stressors. This research aimed to determine the correlation between workload and coping strategies with burnout syndrome in operating room nurses. The method used correlational research with cross-sectional approach. The population in this study was operating room nurses at Karsa Husada Batu Hospital. The number of samples was 26 nurses based on the total sampling technique. The data was collected from the workload questionnaire, ways of coping questionnaire, and Maslach burnout inventory. The data was analyzed using Spearman rank correlation test. The univariate analysis results showed that most of the respondents had a light workload, 16 people (61.5%), the most of respondents used problem-focus coping, 17 people (65.4%), and most respondents experienced low burnout syndrome, 16 people (61.5%). The bivariate analysis showed that workload had a correlation with burnout syndrome (p = 0.000) and coping strategies had a correlation with burnout syndrome (p = 0.032). A light workload and the use of problem-focused coping will reduce work stress experienced by nurses so that the development of burnout does not occur

Different chemical, physical, and physico-chemical methods with addition of optical methods have been used for decades for the development of latent fingerprints (LFPs), even though the choice of a method depends on various factors (type and structure of the surface, external conditions, donor etc.). However, a universal system has not yet been fabricated, while many of those already used are toxic to the humans and the environment. Recently, researchers designed formulations based on (bio)polymeric materials and their specific properties, suitable for targeted interaction with fingerprint (FP) sweat and lipid residues.
Some research groups produced fluorescent properties of particular polymeric materials to map sweat pores, while others encapsulated/incorporated dyes, pigments, etc. into polymeric matrix to obtain formulations of desired color and properties. Additionally, polymer micelles have become interesting due to their amphiphilic properties and the ability to incorporate compounds which could enable multi-colored emission brightness. Nevertheless, (polymeric) nanomaterials are currently of a great importance in material science world, due to specific optical and electronic properties convenient for interaction with FP residues found on different (multi-colored, electroconductive, etc.) substrates.
This paper focuses on (bio)polymer-based systems used to develop LFPs, different approaches of research groups and future possibilities to create the optimal system for specified purpose.

Caffeine, a mild central nervous system (CNS) stimulant present in coffee beans, cocoa beans, and tea leaves, can pose a threat in significant quantities, leading to severe health complications like arrhythmia, tachycardia vomiting, convulsions, coma, and, in extreme cases, death.
We present a case involving the tragic demise of a young woman who took her own life by consuming a sleepiness-preventing medication purchased online, containing caffeine. The autopsy revealed pulmonary edema, congestion, and cutaneous emphysema. The stomach contents included a dark-brown viscous fluid with remnants of tablets and food. Toxicological analysis indicated elevated caffeine levels in various body tissues: femoral blood (195 mg/L), brain (115 µg/g), lung (293 mg/g), liver (202 mg/g), spleen (692 mg/g), kidney (288 µg/g), gall bladder (bile juice) (1500 µg/g), skeletal muscle (163 µg/g), small intestine (236 µg/g), and myocardial muscle (682 µg/g). Due to the presence of caffeine tablets in the stomach, the concentration was exceptionally high and therefore not quantified. The highest concentration of caffeine was found in the bile (1500 µg/g). The gas chromatography mass spectrometry (GC/MS) method used was validated according to the GTFCh guidelines. This case emphasizes the importance of caution and highlights the study's recommendation to address the toxicity risks associated with substances containing high caffeine concentrations. The suggestion is to include caffeine concentration assessments in routine forensic toxicological tests for all cases. In this case the cause of death was determined to be caffeine intoxication, with no trace of ethyl alcohol, drugs, pesticides hydrocarbons, or organic solvents detected in the body samples.
Assessment of the Modern Climate Policy of the European Union
Authors: Alekseev P. V.
Published: June 2024

One of the most important problems of the world community in the 21st century is global warming. To solve this problem, the Paris Climate Agreement was adopted in 2015. As part of the implementation of the Paris Agreement, on December 11, 2019, the European Union (EU) adopted the European Green Deal (EGD), which provides for achieving net zero greenhouse gas emissions by 2050. On July 14, 2021, the EU adopted the climate program Fit for 55, aimed at implementing the EGD. On March 8, 2022, the EU adopted an ambitious strategy to stop importing fossil fuels from Russia and transit to renewable energy sources (REPowerEU). This article aims to assess the modern EU climate policy. The object of the study is the modern climate policy of the EU. The subject of the study is the impact of EU climate policy on the EU’s long-term competitive position in the global economy. The research methodology includes systemic, economic, institutional and logical analysis, induction, deduction and synthesis. Based on the analysis, the author concludes that the modern climate policy of the EU is a logical continuation of the implementation of the Marshall Plan to establish US domination over European countries with the aim of deindustrializing them. As a result of the implementation of this counterproductive policy, which is contrary to the national interests of the member states, the EU is experiencing stagflation, quickly losing its competitive position in the global economy. In this new reality, the EU faces the challenge of reviewing and adjusting climate policy in the region.
Using Machine Learning to Unveil the Dynamics of Insider Trading in Financial Markets
Authors: Tregub I. V. , Wagner A. S.
Published: June 2024

The subject of this study is the insider trading behaviors within the US financial markets, with a focus on transactions by politicians and public officials, and their implications for global economic stability. The purpose is to investigate and analyze these transactions for ethical and legal challenges, and to evaluate their potential impact on market integrity and investor trust. The relevance of this research arises from the substantial influence these figures have on market dynamics, the legal nuances involved in their financial activities, and the broader implications for market transparency and fairness. The scientific novelty is established using econometric modeling and data analytics, particularly the analysis of trading behavior that potentially circumvents the Stop Trading on Congressional Knowledge (STOCK) Act. The methods employed include a Python tool to extract data from financial disclosures and ordinary least squares (OLS) regression to analyze key indicators of insider behavior. The results indicate a significant proportion of trades, approximately 86.67%, were conducted by politicians with noted STOCK Act violations, highlighting a potential gap in the enforcement of current laws and reporting standards. The authors concluded that the findings call for stricter law enforcement, a reevaluation of reporting standards, and comprehensive financial disclosures to maintain market integrity, alongside an urgent need for improved regulatory measures and enhanced transparency mechanisms to mitigate the risks associated with insider trading by individuals in positions of power.

The article provides a comparative analysis of the level of tolerance to uncertainty and strategies of coping with stress caused by a serious illness in single and family women patients. The sample consisted of 50 women patients suffering from stage II–IV breast cancer, the average age was 54.38 ± 10.28 years; the duration of the disease ranged from 3 months to 8 years. The sample is divided into 2 subsamples by marital status: 23 single women and 27 women with a family. Research methods: clinical semi-structured interview (based on the A. Kleiman model); IUS scale (Freeston et al., 1994, in Russian adaptation by A.Sh. Tkhostov, A.S. Nelyubina, A.A. Razlutsky, A.M. Merzlyakova, 2022); СОРЕ (Carver et al., 1989, in Russian adaptation by E.I. Rasskazova, T.O. Gordeeva and E.N. Osin, 2013); Melbourne DecisionMaking Questionnaire (MDMQ) (T.V. Kornilova, 2013); test “The choice of descriptors of intraceptive sensations” (A.Sh. Tkhostov, S.P. Elshansky, 2003; modification by A.S. Nelyubina, A.Sh. Tkhostov, 2013). It was revealed that single patients significantly more often than those with a family used such adaptive strategies as vigilance, planning and acceptance. At the same time, patients of both groups did not resort to seeking social support in coping with the disease. The higher the patient’s tolerance to uncertainty, the more often she chose maladaptive coping strategies such as over-vigilance, procrastination and avoidance.
MEDIA SPACE AS A PART OF COMMUNICATIVE SPACE AND MATERIAL- IDEATIONAL SYSTEM
Authors:   Russian State University for the Humanities, Zorin Kirill A.
Published: June 2024

The article presents a view of media and communicative space from the perspective of the synergetic paradigm. It is proposed to consider the communicative space as a material- ideational self-organising system, as a result of the evolution of which media space emerged. That kind of an approach allows studying the emerging fusion of the mass and interpersonal communication, which affects the work of editorial offices. The article describes the elements of such a system, which the author describes as: the subjects of communication, the place of their interaction, media (from symbolic to technical) and knowledge and conventions as the subject and result of communication.
