Authors: Ge Zhibin , Xia Qionghua
Published: August 2024

Teaching has gradually become more important, no matter which aspect of teaching must be continuously improved and kept up with the pace of development. Aerobics teaching has not been paid much attention by the masses, and many remain in the traditional teaching mode, which will delay the development of aerobics. This paper conducts an in-depth study of aerobics mixed teaching and action analysis guidance under data mining: (1) The blended learning and data mining are fully explained, and only when the two are integrated can better research be carried out. (2) The research on aerobics movements is very complicated. The process and form of the movements are analyzed through the skeleton time graph convolution and spatial graph convolution, and the action probability PCA model is established to facilitate the public study. (3) Blended learning and traditional learning of aerobics After in-depth comparison, it is found that blended learning has more advantages than traditional learning in many aspects. The learning mode should keep pace with the times, and blended learning can better teach.

Can VO2max be accurately estimated using exercise-duration based prediction equations and a nomogram?
Authors: Adam Natalie A. , Duquette Adriana M.
Published: August 2024

Study aim: The purpose of this study was to examine a large cohort of young Canadian adults to determine if exercise time from a maximal Bruce Treadmill Protocol could accurately predict measured VO2max values by inputting the total exercise time into prediction equations and a nomogram.

Materials and methods: 550 kinesiology undergraduate student (280 male and 270 female) participants, with a mean body mass (BM) of 72.08 ± 15.05 kg, mean age of 21.16 ± 1.26 years old and mean height of 171.95 ± 10.25 cm completed a maximal graded exercise test to obtain their VO2max (measured). Predicted VO2max was calculated with various equations using the variable of total exercise test time. Linear regression models were created to determine how well the predicted VO2max values compared to the measured values.

Results: Across all VO2max calculation methods, males obtained higher VO2max values on both the measured (49.89 ± 9.21 mL/ kg/min) and predicted values (46.04–55.40 mL/kg/min) and exercised for a longer duration of time (14.33 minutes) compared to females (40.89 ± 7.50 mL/kg/min, 38.87–48.36 mL/kg/min, 11.92 minutes). Classifications and percentile rankings were created using each measured and predicted method.

Conclusions: The Healthy Persons Equation [6], Healthy Men and Women Equation [2], Active and Sedentary Women/Men Equations [10, 22] and nomogram [13] cannot accurately predict VO2max in healthy young adults, with R2 values between 0.38–0.50. The Healthy Persons Equation [6] was found to very closely mimic the seven-category classifications determined from the measured CPET VO2max values.

Objective. Genetic factors substantially contribute to the development and duration of arterial hypertension. The study of the A1166C polymorphism of the angiotensin II type 1 receptor gene (AGTR1) in arterial hypertension is an auspicious area for assessing the relationship between heredity, hypertension development, and adipokines, but it still remains debatable. The purpose of the current study was to investigate serum adipokines levels depending on the AGTR1 A1166C polymorphism.

Methods. A total of 86 patients with arterial hypertension were examined, who underwent the evaluation of the allelic A1166C polymorphism of AGTR1 by polymerase chain reaction with electrophoretic detection and determination of serum adipokines levels using enzyme-linked immunosorbent assay.

Results. In the group of patients with arterial hypertension, a significant increase in serum adipokines (resistin, adiponectin, and leptin) levels was found against the background of a decrease in the antianorexic hormone ghrelin with a predominance of CC genotype carriers compared with AA genotype carriers of the AGTR1. A statistically significant decrease in ghrelin and an increase in serum adipokines (resistin, adiponectin, and leptin) in CC genotype carriers compared with AA genotype carriers of the AGTR1 were found suggesting that CC genotype carriers may be predictors of the development of arterial hypertension in our patients.

Conclusions. Statistically significant decrease in ghrelin and increase in serum adipokines (resistin, adiponectin, and leptin) were found in CC genotype carriers compared with AA genotype carriers of the AGTR1, which suggests that carriers of the CC genotype are predictors of the arterial hypertension development in our patients.
Remarks on the Increasing of Liability of for Certain Traffic Offences
Authors: Łucarz Katarzyna
Published: August 2024

The author discusses the nature and scope of changes introduced to the Code of Petty Offences and the Code of Procedure in Petty Offences Cases by the Act of 2 December 2021. The amendment represents a drastic intervention by the legislator in the current legal framework regarding offences against safety and order in transportation. It foresees significant modifications in the legal and criminal response to these offences, transformations in the characteristics of selected types of prohibited acts, and proposes entirely new types of prohibited acts. The analysis suggests that the guiding principle behind these changes is to increase the degree of punitiveness of petty offences law towards perpetrators of traffic violations. This legislative approach raises concerns about the instrumental use of petty offences law with respect to the perpetrators of these offences. The adopted direction of changes raises suspicions that the legislator has not thoroughly familiarised themselves with the matter covered by their intervention. In any case, it is not grounded in the current state of traffic criminality, or in the analysis of judicial practice. An increase in repressiveness has never directly translated into a reduction in traffic criminality. The latter is a much more complex problem, involving the necessity of multi-faceted references.

An optimized integral performance criterion based commercial PID controller design for boost converter
Authors: Irshad Mohammad , Vemula Naresh Kumar , Devarapalli Ramesh , Kumar Gundavarapu Venkata Nagesh , Knypiński Łukasz
Published: August 2024

Boost converters often face challenges such as sluggish dynamic behavior, inadequate voltage regulation, and variations in input voltage and load current. These issues necessitate the need for closed-loop operation. Nature-inspired optimization algorithms (NIOA) have demonstrated their effectiveness in delivering enhanced solutions for various engineering problems. Several studies have been conducted on the use of proportional-integral-derivative (PID) controllers for controlling boost converters, as documented in the literature. Some studies have shown that using fractional order PID (FO-PID) controllers can lead to better performance than traditional PID controllers. Nevertheless, implementing FO-PID can be quite complex. Considering the widespread use of commercial PID controllers in industrial settings, this study focuses on finding the best tuning for these controllers in DC-DC boost converters. The approach used is particle swarm optimization (PSO) based on integral performance criteria. Simulation results indicate that the proposed controller achieves superior performance, evidenced by the lowest settling time, overshoot, integral absolute error (IAE), and integral squared error (ISE) values under varying input voltage and load current conditions, compared to both PID and FO-PID controllers. These findings have been confirmed through hardware implementation, which demonstrates the effectiveness of the proposed controller.
Comparative performance analysis of robust and adaptive controller for three-link robotic manipulator system
Authors: Sweta  , Deolia Vinay Kumar , Kumar Jitendra
Published: August 2024

Three-link robotic manipulator systems (TLRMS) often used in automation industries offer many capabilities, but become very complex in terms of their control and operations. In order to enhance trajectory tracking in the X and Y axes, this study investigates the application of a fractional-order nonlinear proportional, integral, and derivative (FONPID) controller for a three-link robotic manipulator system (TLRMS). Using a cost function that combines the integral of square error (ISE) and the integral of absolute change in controller output (IACCO), the cuckoo search algorithm (CSA) maximises the performance of the controller. The fractional-order term enhances the robustness and the nonlinear term supports the adaptiveness of the FONPID controller. The fractional-order proportional, integral, and derivative (FOPID) and classic PID controllers are contrasted with the FONPID controller's efficacy. The findings show that the CSA-tuned FONPID performs better than the other controllers, providing more robust and accurate tracking. By demonstrating fractional-order control's promise for intricate robotic systems, this study advances the discipline.
Series partial power converter with half bridge LLC series resonant converter for PV application
Authors: Kurichiparambil Sebin Davis , Jegathesan Varghese
Published: August 2024

This study proposes a series partial power converter with a half-bridge LLC series resonant converter for photovoltaic (PV) applications. The main advantage of the implementation of a partial power converter with LLC series resonant converter is zero voltage switching (ZVS) operation of primary side enables the converter to work at a higher switching frequency. The partial power topology used in the proposed converter enables low power rating switches in the primary, which in other terms reduces the primary current. The proposed converter achieves excellent efficiency due to its ZVS and partial power operating capabilities. The valuation of the proposed converter is done in MATLAB Simulink with a 300 W PV module, which is made to operate in varying irradiance and module temperature of 25 °C. The operational waveforms and the power outputs obtained when the proposed converter is implemented by using perturbation and observation (P&O) maximum power point tracking (MPPT) control algorithm are discussed in this paper.
Morphological and molecular characterisation of the nematode parasite Graphidioides affinis (Secernentea: Trichostrongylidae) in Patagonian maras, Dolichotis patagonum, kept in a zoo in Sofia, Bulgaria
Authors: Panayotova-Pencheva Mariana , Laskowski Zdzisław , Pyziel Anna Maria
Published: August 2024

Introduction

Patagonian maras, rodents endemic to South America, are classified as a near-threatened species. Various factors affect their health including parasitic diseases. The aim of this study was to perform morphometric, molecular and phylogenetic characterisation of one such parasitic disease agent, the nematode Graphidioides affinis, specimens of which were found in captive Patagonian maras.

Material and Methods

In March 2023, 18 Patagonian maras kept at the Sofia Zoo in Bulgaria were investigated with the use of coprological methods. Following the investigation, the animals were dewormed with the use of albendazole. Dead adult nematodes found in the faeces of dewormed maras were collected and preserved in 70% ethanol, and morphometrically, molecularly and phylogenetically analysed.

Results

The morphometric analyses confirmed the nematodes to be Graphidioides affinis. The partial nucleotide sequences of the small subunit ribosomal rDNA (SSU), the internal transcribe spacer 2 (ITS2) and the large subunit ribosomal DNA (LSU) of G. affinis were obtained. These are the first available nucleotide sequences of this parasite. The phylogenetic analyses of the species showed its distinctiveness in comparison to other gastrointestinal nematodes, as it was grouped separately.

Conclusion

The Patagonian maras kept in a European zoo retained their original parasitofauna which are related to South America.
Contribution to a New Algorithm to Perform an Automatic Self-Calibration of Current Sensors

Published: August 2024

Sensors calibration plays a crucial role in controlling systems and achieving fault-tolerant control by ensuring accuracy, performance, safety, energy efficiency, and compliance with standards. It is an essential to maintain the reliability and effectiveness of modern control systems across various applications. In this paper, we represent a new algorithm that processes a set of raw data collected by a sensor to find the mapping function that relates the raw data to the real value of the measured signal by the sensor. Working on sensors with an unknown mapping function, unknown parameters, or with external disturbances, that affects their behaviour, represents a problem; moreover, it takes a lot of time and effort to calibrate the sensor before each use. Several techniques were used to overcome these aspects mostly by recording the output of the sensor for different input values that change manually, to calibrate the sensor. However, the represented technique in this paper can easily provide us with the input/output model of a specific sensor by doing only one experiment; it also improves the accuracy of the measurements as it is a self-calibrating technique that reduces the nonlinearity and noise problems to deliver a better estimation of the measured signal, which is validated in this paper experimentally using a low-cost current sensor by comparing the obtained results from this algorithm with the results using the extracted input/output model illustrated in the datasheet. Furthermore, if the sensor is pretty poor, and if the application requires more precision, the provided estimation by the mapping function can be mixed with other sensor/s readings using sensor fusion algorithms to find a more precise value of the input. The represented algorithm can also perform self-calibration while evaluating the functionality of the application and the variations of the temperature and other external disturbances that affect the sensor.
Micromechanical Modeling for Analysis of Shear Wave Propagation in Granular Material
Authors: Derbane Said , Mansouri Mouloud , Messast Salah
Published: August 2024

This paper presents a numerical study of shear wave propagation in a vertical sand profile through micromechanical modeling. For this purpose, 2D modeling by the Discrete Element Method (DEM), is carried out. The DEM model is based on molecular dynamics with the use of circular elements. The intergranular normal forces at contacts are calculated through a linear viscoelastic law, while the tangential forces are calculated through a perfectly plastic viscoelastic model. Rolling friction is incorporated to account for the damping of the grains rolling motion. Different boundary conditions of the profile have been implemented: a bedrock at the base, a free surface at the top, and periodic boundaries in the horizontal direction. The sand deposit is subjected to a harmonic excitation at the base. The simulations carried out have well reproduced the elastic and damping features relative to shear wave propagation in a vertical soil deposit. The excitation frequency is varied to better understand the phenomenon of wave propagation in granular medium. The conducted simulations highlighted a number of features of soil deposits response subjected to harmonic excitation at the base, including the movement amplification, the resonance phenomenon and the limitation of the displacement at the resonance. The micromechanical analysis showed that the intergranular slips increase with increasing the involved strain level. An inverse analysis is performed to determine a continuum-damped linear elastic model, whose response is similar to that of the discrete-element model. This analysis showed that the wave propagation velocity of the equivalent continuum model decreases with increasing excitation frequency. This finding could be attributed the decrease of shear modulus of the granular material as the deformation level increases.

Published: August 2024

Genotype × environment (G×E) interaction is a major challenge in selecting superior genotypes based on growth traits in Eucalyptus since phenotypic variability is significantly affected by environmental heterogeneity. The aim of the present investigation was to understand the relationship between wood property traits and fibre biometry in the bi-parental mapping population of E. camaldulensis × E. tereticornis across three locations and identify stable genotypes based on multiple traits to improve prediction accuracy in breeding programs. High broad-sense heritability was documented for fibre parameters indicating a good prospect of these traits for genotype selection in hybrid breeding programmes in Eucalyptus. Significant positive correlation of fibre parameters with cellulose, acoustic velocity, DMoE and negative correlation with lignin reiterate that the fibre traits can be improved by the selection of genotype for improved wood property traits. Multi-Trait Stability Index (MTSI) and weighted average of absolute scores of the genotype index (WAASB) short-listed four genotypes (C343, C327, C246 and C161) with improved wood property traits and the mean of selected genotypes for all traits was significantly higher than the grand mean of the overall genotypes. The identified superior and stable genotypes with improved wood properties and fibre biometry can be used in plantation programs or as genitors in breeding programs.
Why Budgeting in Small and Medium Enterprises Matters?
Authors: Srbinoska Dusica Stevcevska , Hristova Snezhana , Kazic Viktorija
Published: August 2024

Businesses utilize budgets to prioritize and allocate limited resources effectively, ensuring the smooth operation of essential events and activities. Effective budget management is pivotal for successful resource allocation, particularly for small and medium-sized enterprises (SMEs) which often face challenges during their initial stages, with ineffective budgeting being a significant contributor to failure. Budgets serve as a reflection of a firm’s strategy. This study aims to evaluate the influence of the budgeting process on the financial performance of SMEs in North Macedonia, exploring both the merits and drawbacks of budgeting as a management tool. To the best of the authors’ knowledge, this research is the first to connect the conceptual frameworks of budget incremental theory, priority-based budgeting theory, and risk-based budgeting theory with empirical evidence and conclusions specific to North Macedonia. The study also delves into potential challenges SMEs encounter in budget planning and decision-making Drawing from primary data collected through a validated survey administered to 45 Macedonian SMEs, empirical findings highlight that budgeting practices account for approximately half of the variations in SME financial performance. This suggests that, alongside budget planning, management, coordination, communication, and review processes, there are other significant factors influencing SME financial performance. Further exploration is warranted to identify these factors and their impacts on firm performance.

Analogy, dialectics, myth and catastrophe in Plato
Authors:   St. Petersburg University of the Ministry of Emergency Situations of Russia, Shevtsov Konstantin
Published: August 2024

Plato, dialectics, myth, catastrophe, transition, dimension of space, figure of the philosopher Abstract. Plato defines dialectics as a transition from many to one and from one to many, as well as an ascent from limited premises to a non-presupposed beginning. The problem is posed by the fact that the transition that Plato talks about is essentially a transition from the corporeal to the incorporeal and from the human to the divine. This means that we cannot have a simple method of this transition and we have to look for help in other approaches that Plato also uses. In the article, we take as the subject of analysis Plato's way of using analogy and myth. In a number of Plato's dialogues (Republic, Phaedrus), one can see an appeal to the analogy of cognition with the transition from a flat to a three-dimensional space. Mythological narratives about the catastrophe that happened to the cosmos in the past (Politician, Timaeus) allow us to assume the interaction of the cosmos with the divine space, which has a different dimension than a three-dimensional body. The image of a three-dimensional body on a plane inevitably carries a lot of contradictions that are removed in three-dimensional space, and also exactly the contradictions of the corporeal cosmos can be removed in the surrounding body of the hyperourania region, which can only be seen by the disembodied gaze of the mind. Thus, analogy and myth are not separated from dialectics, but, on the contrary, are invoked by it as a necessary complement that gives support to the mind for the transition from human knowledge to pure knowledge of things in themselves. This knowledge changes the thinker himself; the article shows how the figures of thinkers in Plato's dialogues change depending on whether he acts as a researcher or someone who has already acquired higher knowledge.
Dialogue Theages and the aporias of education
Authors:   Novosibirsk State Technical University (Russia), Morgunov Georgy
Published: August 2024

The article examines Plato's dialogue Theages. By meticulously preserving the dialogue, the author concludes that various perplexities found in other Plato dialogues, such as the Symposium and Theaetetus, can be unraveled. The interconnection between them becomes apparent in the shared interpretation of concepts like daimonion in the Theages, Eros in the Symposium, and the nameless god in the Theaetetus. This deity influences Socrates' approach to wisdom, suggesting that the pursuit of philosophy is the art of love. Synousia, defining Socrates' relationship with his students and encompassing, among other things, erotic practices, is crucial for such training. The author proposes that a careful examination of the Symposium and Theaetetus can elucidate the enigmatic fragments in the Theages, thereby acknowledging the educational and disciplinary system of antiquity reflected in these dialogues.
Sapphic “on richly-worked throne Aphrodite” (once again about the epithet ποικιλόθρονος in Sappho)
Authors:   Novosibirsk State University, Myakin Timothey
Published: August 2024

This article about epithet ποικιλόθρονος exposes some new arguments in the light of the latest archaeological data, which support the latest views on the female circle of Sappho as a religious community confirmed historically. This epithet can be best understood if it is correlated with the figurines from the Temple of the Mother, whose temple in the era of Sappho was the main cult center of Mytilene (7th–6th centuries BC, cf. Rungu 2013, 138). The first part of this epithet (ποικιλό-), therefore, most likely refers to the lion figure that lies on the lap of this goddess. Cf. Bolling 1958.

Published: August 2024

In the article, using the example of thematic publications contained in large specialized and university journals published in Russia in the second half of the 19th – early 20th centuries, the reception of Aristotle’s heritage is studied. It is shown that during the period from 1843 to 1915 no less than 94 scientific works related to Aristotle were published. Among them are articles (series of articles), book reviews, translations of Aristotle’s treatises into Russian, and scientific presentations. Moreover, most of the publications date from the 1890s, and thematically, the largest number of works relate to “Athenian Constitution” and Aristotle’s “Politics”. The article is devoted to the analysis of these thematic publications. A “Bibliographic List” of works related to Aristotle is published in the appendix to the article.

Aristotle on the causes of sleep
Authors:   Institute of Philosophy RAS (Moscow), Mesyats Svetlana
Published: August 2024

For more than half a century, scholars have been debating how many causes of sleep were discussed by Aristotle in the treatise On Sleep and Wakefulness (De Somno et Vigilia). Some commentators believed that Aristotle did not offer a formal explanation of sleep, others argued that sleep has no material cause, still others do not find either effective or final cause of it. The controversy is provoked by the very course of reasoning in the treatise, in the middle of which Aristotle promises to investigate all four causes of the sleep, but further on doesn’t say a word about either its form or matter. As for the efficient cause of sleep, it also remains highly controversial. Scholars disagree as to what physiological change in the animal body makes the central organ of perception incapable of perceiving – whether it is due to the heart being cooled, or warmed, or compressed by blood in a mixed condition. In the present paper I intend to propose a new interpretation of Aristotle’s theory of sleep in the light of recent discussions about the causes of sleep in Parva naturalia. To achieve this goal, I examine Aristotle’s explanatory method in the De anima, focusing on the question of whether sleep along with other living being’s activities involving soul and body (λόγοι ἔνυλοι), can be explained in terms of formal, final, material and effective causes. Particular attention is paid to the role of material and effective causes in the physiological explanation of sleep. While reconstructing Aristotle’s explanatory method I clarify the structure of the argument in the De Somno and resolve some of the problems concerning the unity of this work.
Narrative persons in Tertullian’s Trinity
Authors:   Institute of Philosophy and Law SB RAS, Butakov Pavel
Published: August 2024

Tertullian employs two distinct ways of describing the Trinity in his work Adversus Praxean: a metaphysical and a narrative description. He specifically uses the term “persona” to refer to the Father, Son, and Holy Spirit only in the narrative description, indicating a character in the story. In a dogmatic context, he prefers the metaphysical term “gradus” instead. It was later generations of Christian theologians who transformed Tertullian’s narrative term ‘person’ into a dogmatic term. Tertullian would have objected to the formula “one God in three Persons.” Therefore, the widely held belief that he authored the formula is misleading.
On the wits and ardour in Plato’s Symposium: Socrates’ educator’s formula of love in Alexander Kushner’s poem
Authors:   The Dostoevsky Russian Christian Academy for the Humanities (St Petersburg, Russia), Sinitsyn Alexander A.
Published: August 2024

The article examines a poem written by a contemporary Petersburg poet, Alexander Semyonovich Kushner “And what a foreign lady said…” The poet mentions the Athenian thinker Socrates and a foreign lady, never giving her name. It is clear that he speaks about the priestess Diotima of Mantinea (an ancient city in Arcadia), with whom Socrates, a character in Plato’s dialogue Symposium (Plato, Symp. 201d–212b) conversed. Why should the story of love told by the Mantinean priestess have failed to inspire the Russian poet when he read it for the second time (“this time”)? Why did Kushner think that Symposium is “less about ardour, / Than a long invocation of wits”? It is the most erotic not only in Plato’s works but also in the whole classical philosophy. Diotima praises Eros’s might and valour, she calls him a great genius, a mediator between the immortal and the mortal. Socrates’ educator in “the philosophy of love” says that love is an ascent from the contemplation of the physical beauty to the contemplation of the beauty proper (Plato, Symp. 210а–212а). What the priestess in the ancient Greek philosopher’s dialogue tells about love, virtue, aspiration to engender the beautiful and the immortal, Kushner “applies” to the experience of earthborn sentiment. In his “antiquity-oriented” poem he does not agree with the “formula of love” proposed by Diotima (Socrates = Plato). The poet seems to regard “the Diotima formula” as abstract, divorced from reality, which is more multifaceted and complicated than any theory. In this “non-platonic” work, Kushner estranges himself from Plato’s Symposium and says that love cannot comply with any “formula”.

The article is devoted to the identification and description of a speculative innovation that was clearly formed in Plato, which we designate as “the axiology of the smooth and the rugged.” According to this speculative innovation, smoothness is seen as a sign of perfection — as understood by Plato and the philosophers who influenced him — and the opposite characteristics of smoothness, such as ruggedness or roughness, as the absence of this perfection. The “axiology of the smooth and the rugged” is first explicitly stated in the passage about the “true Earth” from the “Phaedo”, as a part of Socrates’ visualization of the afterworld awaiting philosophizing souls after death (Pl. Phaed. 110a–e). The fantastic landscape from the “Phaedo” contains descriptions of smooth, transparent and beautifully colored stones and mountains, as well as a description of the Earth as a “sphere of twelve pentagons” (dodecahedron), equally beautifully coloured. The article undertakes an analysis of all of the listed visual signs of perfection, with an emphasis on their connection with smoothness. Despite the fact that highlighting the special status of smoothness is Plato’s innovation, we present it as part of a more ancient speculative field, which include (i) the special status of the “perfectly rounded Sphere” in Parmenides, (ii) Heraclitean ontologization of precious materials (gold) and (iii) early Pythagorean ideas related to the special status of the dodecahedron. A distinction is made between this field and the ideas of Empedocles and Democritus that do not belong to it. All visual elements of the “true Earth” are presented as visual philosophy and their interpretation as “metaphors” is criticized. At the end, an outline is made of possible applications of the “axiology of smooth and rugged” in the interpretation of various phenomena in the history of philosophy and visual culture. Although there are countless interpretations of the “Phaedo”, analyzes of the visual component of the myth of the afterlife are very rare, and among them there is not a single one that draws attention to the importance of smoothness. Accordingly, our analysis is being done for the first time.

The positivist-oriented historiography of medical history based on the idea of “progress” has bequeathed us with a legacy of perceiving Paracelsus as a great reformer of sixteenth-century medical theory and practice, heralding modern “science”. This model has been subjected to scathing critique by the intellectual history of medicine. Relying on historical and philological methods, this approach have illuminated the semantic gaps between “Paracelsianism” and Paracelsus' own doctrines. In consonance with intellectual history of medicine, recent years have witnessed a trend towards a more pronounced distinction between the theories of “plague” epidemics from Paracelsus' treatises and pseudo- Paracelsian works. Researchers identify three principal difficulties in reconstructing Paracelsus' medical theories: his obscure style, the “inconsistency” of ideas across treatises, and the “vagueness” of conceptual foundations. The article elucidates these problems by reconstructing key elements of the “plague” theory in Volumen medicinæ Paramirum, partially resolving them through philosophical hermeneutics. Paracelsus uses the “plague” example to expose the ignorance of medical authorities like Galen and Avicenna, while appropriating and redefining conventional medical concepts, particularly “plague” and its “causes.” His alternative theory links epidemics and diseases to five entities (entia), conceptualised within paraconsistent logic and his microcosm-macrocosm doctrine. Particular attention is paid to the concept of astral essence (ens astralis). The appendix presents a commented Russian translation of several sections of the treatise.
The Images of Eros: Love and Communion with God in the Writings of Michael Psellos and Symeon the New Theologian

The paper deals with the theme of love and communion with God in the writings of Michael Psellos and Symeon the New Theologian. In the first case, the material for analysis was the poetical interpretation by Michael Psellus on the Song of Songs. In the Christian tradition, the text is interpreted as a story about the mystical union of God and the soul. In the second case, the I Catechetical Discourse is analyzed, containing a detailed teaching about love as divine energy. It is concluded that Michael Psellos understands love for God and, accordingly, union with Him in a mystical marriage as a moral imitation of the human soul to God, who is genuine love and who is in the proper sense unknowable. Symeon the New Theologian, on the contrary, interprets love as something that belongs to God, but embraces both the divine and the created spheres, due to which it is possible not only to imitate an intelligent creature to the Creator, but to perceive His contemplation and ultimately union with Christ as the bodily embodiment of divine love. The difference in the ecclesiological views of the two thinkers is especially emphasized: if Michael Psellos understands the Church as a union of those who imitate Christ, then Symeon the New Theologian as a community of those who visibly see Christ and strive to unite with Him.
Structure and transport properties of LiTFSI-based deep eutectic electrolytes from machine learning interatomic potential simulations

Deep Eutectic Solvents have recently gained significant attention as versatile and inexpensive materials with many desirable properties and a wide range of applications. In particular, their similar characteristics to ionic liquids, make them a promising class of liquid electrolytes for electrochemical applications. In this study, we utilized a local equivariant neural network interatomic potential model to study a series of deep eutectic electrolytes based on lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) by molecular dynamics (MD) simulations. The use of equivariant features combined with the strict locality result in highly accurate, data-efficient and scalable interatomic potentials enabling large-scale MD simulations of these liquids with first-principles accuracy. Comparing the structure of the liquids to reported results from classical force field (FF) simulations indicates that ion–ion interactions are not accurately characterized by FFs. Furthermore, close contacts between lithium ions bridged by oxygen atoms of two amide molecules are observed. The computed cationic transport numbers and the estimated ratios of Li–amide lifetime (τ[Li–amide]) to the amide’s rotational relaxation time (τ[R]), combined with the ionic conductivity trend, suggest a more structural Li+ transport mechanism in the LiTFSI:urea mixture through exchange of amide molecules. However, a vehicular transport could have a larger contribution to Li+ ion transport in the LiTFSI:N-methylacetamide electrolyte. Moreover, comparable diffusivities of Li+ cation and TFSI – anion and a τ[Li–amide]/τ[R] close to unity, indicate that vehicular and solvent-exchange mechanisms have rather equal contributions to Li+ ion transport in the LiTFSI:acetamide system.
PM6-ML: The Synergy of Semiempirical Quantum Chemistry and Machine Learning Transformed into a Practical Computational Method
Authors: Nováček Martin , Řezáč Jan
Published: August 2024

Machine learning (ML) methods offer a promising route to the construction of universal molecular potentials with high accuracy and low computational cost. It is becoming evident that integrating physical principles into these models, or utilizing them in a ∆-ML scheme, significantly enhances their robustness and transferability. This paper introduces PM6-ML, a ∆-ML method that synergizes the semiempir- ical quantum-mechanical (SQM) method PM6 with a state-of-the-art ML poten- tial applied as a universal correction. The method demonstrates superior perfor- mance over standalone SQM and ML approaches and covers a broader chemical space than its predecessors. It is scalable to systems with thousands of atoms, which makes it applicable to large biomolecular systems. Extensive benchmarking confirms PM6-ML’s accuracy and robustness. Its practical application is facili- tated by a direct interface to MOPAC. The code and parameters are available at https://github.com/Honza-R/mopac-ml.

Dynamics of epigenetic modifications such as acetylation and deacetylation of histone proteins have been shown to be crucial for the life cycle development and survival of Plasmodium falciparum, the deadliest malaria parasite. In this study, we present a novel series of peptoid-based histone deacetylase (HDAC) inhibitors incorporating nitrogen-containing bicyclic heteroaryl residues as a new generation of antiplasmodial peptoid-based HDAC inhibitors. We synthesized the HDAC inhibitors by an efficient multicomponent protocol based on the Ugi four-component reaction. The subsequent screening of 16 compounds from our mini-library identified 6i as the most promising candidate, demonstrating potent activity against asexual blood-stage parasites (IC50 Pf3D7 = 30 nM; IC50 PfDd2 = 98 nM), low submicromolar activity against liver-stage parasites (IC50 PbEEF = 0.25 µM), excellent microsomal stability (t1/2 > 60 min), and low cytotoxicity to HEK293 cells (IC50 = 136 µM).
