Influence of cooperation on the event-related potentials in verbal creative and noncreative tasks performance
Authors: Nagornova Zh. V. , Shemyakina N. V.
Published: August 2024

This study examines the effects of social interaction conditions on brain correlates of verbal creativity. A model of cooperation is considered in the study in which participants were to work together without conferring and create as many answers as possible in creative and non-creative tasks. Subjects (4 males, 26 female) performed two types of tasks individually and cooperatively in pairs (male-male, female-female): creative task – to create as many as possible unusual use of an everyday object, and non-creative task – to list items from the proposed categories. Event-related potentials (ERPs) in each of the tasks were compared between the cooperative and individual performance conditions. The cooperative conditions demonstrated decrease in the amplitude of the P200 component at a time interval of 148–272 ms from the onset of stimulus presentation for both creative and non-creative tasks performance, reflecting reduced attention allocation to the stimulus in the social interaction condition. When performing a creative task, a larger amplitude of the late positive component was observed in the 662–1240 ms interval in the posterior temporal and occipital areas, which may reflect activation of the temporoparietal junction involved in the processes of understanding the other. The number of answers (productivity) was significantly lower in cooperative conditions compared to individual task performance.
Computer-algebraic approach to first differential approximation: Van der Pol oscillator
Authors: Blinkov Yu. A.
Published: August 2024

First differential approximation has been used to analyze various numerical methods for solving systems of ordinary differential equations. This has made it possible to estimate the stiffness of the ODE system that models the oscillations of the Van der Pol oscillator and the error of the method as well as to propose simple criteria for choosing a calculation step. The presented methods allow one to perform efficient calculations using computer algebra systems.
Integration of a degenerate system of ODEs
Authors: Bruno A. D. , Edneral V. F.
Published: August 2024

The integrability of a two-dimensional autonomous polynomial system of ordinary differential equations (ODEs) with a degenerate singular point at the origin that depends on six parameters is investigated. The integrability condition for the first quasihomogeneous approximation allows one of these parameters to be fixed on a countable set of values. The further analysis is carried out for this value and five free parameters. Using the power geometry method, the system is reduced to a non-degenerate form through the blowup process. Then, the necessary conditions for its local integrability are calculated using the method of normal forms. In other words, the conditions for the parameters under which the original system is locally integrable near the degenerate stationary point are found. By resolving these conditions, we find seven twoparameter families in the five-dimensional parametric space. For parameter values from these families, the first integrals of the system are found. The cumbersome calculations that occur in the problem under consideration are carried out using computer algebra.

Published: August 2024

Different implementations of Clifford algebra: spinors, quaternions, and geometric algebra, are used to describe physical and technical systems. The geometric algebra formalism is a relatively new approach, destined to be used primarily by engineers and applied researchers. In a number of works, the authors examined the implementation of the geometric algebra formalism for computer algebra systems. In this article, the authors extend elliptic geometric algebra to hyperbolic space-time algebra. The results are illustrated by different representations of Maxwell’s equations. Using a computer algebra system, Maxwell’s vacuum equations in the space-time algebra representation are converted to Maxwell’s equations in vector formalism. In addition to practical application, the authors would like to draw attention to the didactic significance of these studies.

Authors: Gevorkyan M. N. , Korol’kova A. V. , Kulyabov D. S. , Sevast’yanov L. A.
Published: August 2024

In their research, the authors actively exploit different branches of geometry. For geometric constructions, computer algebra approaches and systems are used. Currently, we are interested in computer geometry, more specifically, the implementation of computer graphics. The use of the projective space and homogeneous coordinates has actually become a standard in modern computer graphics. In other words, the problem is reduced to the application of analytic projective geometry. The authors failed to find a computer algebra system that could implement projective geometry in its entirety. Therefore, it was decided to partially implement computer algebra for visualization of algebraic relations. For this purpose, the Asymptote system was employed.

Searching for laurent solutions of truncated systems of linear differential equations with the use of EG-eliminations
Authors: Ryabenko А. А. , Khmelnov D. E.
Published: August 2024

Laurent solutions of systems of linear ordinary differential equations with the truncated power series coefficients are considered. The Laurent series in the solutions are also truncated. We use induced recurrent systems for constructing the solutions and have previously proposed an algorithm for the case when the induced system has a non-singular leading matrix. The algorithm finds the maximum possible number of terms of the series in the solutions that are invariant with respect to any prolongation of the original system. Below we present advances in extending our algorithm to the case when the leading matrix is singular using algorithm EG as an auxiliary tool. The implementation of the algorithm as a Maple procedure and examples of its usage are presented.
Solving rician data analysis problems: theory and numerical modeling using computer algebra metods in Wolfram Mathematica
Authors: Yakovleva T. V.
Published: August 2024

This paper considers theoretical foundations and mathematical methods of data analysis under the conditions of the Rice statistical distribution. The problem involves joint estimation of the signal and noise parameters. It is shown that this estimation requires the solution of a complex system of essentially nonlinear equations with two unknown variables, which implies significant computational costs. This study is aimed at mathematical optimization of computer algebra methods for numerical solution of the problem of Rician data analysis. As a result of the optimization, the solution of the system of two nonlinear equations is reduced to the solution of one equation with one unknown variable, which significantly simplifies algorithms for the numerical solution of the problem, reduces the amount of necessary computational resources, and enables the use of advanced methods for parameter estimation in information systems with priority of real-time operation. Results of numerical experiments carried out using Wolfram Mathematica confirm the effectiveness of the developed methods for two-parameter analysis of Rician data. The data analysis methods considered in this paper are useful for solving many scientific and applied problems that involve analysis of data described by the Rice statistical model.
Study of the Effect of Radiation Exposure on Grain Size and Mechanical Properties of Thin-Film Aluminum
Authors: Dyuzhev N. A. , Gusev E. E. , Portnova E. O. , Makhiboroda M. A.
Published: August 2024

For the first time, an experimental dependence of the grain size and mechanical properties of a thin-film aluminum material on the dose of short-wave radiation has been obtained. A thin film of aluminum was formed on a silicon substrate using magnetron sputtering. The effect of a decrease in mechanical strength and biaxial elastic modulus with increasing radiation dose was identified. This effect is explained by a decrease in grain size and roughness on a thin-film aluminum membrane. For the microscopically measured range of aluminum grain sizes, the inverse Hall-Petch relation is used. During the research, it was determined that during irradiation the number of grain boundaries and the number of grains themselves increases, which leads to an increase in the likelihood of deformation.
Influence of Pore Shape and Initial Stress State on the Electroelastic Properties of Porous Piezoceramics PZT-4
Authors: Pankov A. A.
Published: August 2024

A numerical-analytical solution to the “effective modulus problem” of transversally isotropic porous ceramics is obtained, taking into account its initial stressed state and the ellipsoidal shape of oriented pores of various connectivity based on the solution of the associated stochastic boundary value problem of electroelasticity of composite mechanics using the Green’s function method. A numerical calculation of the initial and resulting values of the effective piezoelectric modulus of porous piezoceramics (PZT-4) was carried out depending on the values of the volume fraction, shape parameter and connectivity of ellipsoidal, in particular: spherical, disk or tunnel pores, taking into account the initial stressed state of the porous piezoceramics due to its initial axisymmetric deformation. Characteristic values of the volume fraction of spherical and disk pores are identified, taking into account their connections, at which the sign of the numerical values of the initial effective piezoelectric modulus changes with respect to the corresponding module of PZT-4 monolithic ceramics. The values of the volume fraction, shape parameter and type of pore connectivity at which the maximum gradients of the linear dependence of the values of the resulting piezoelectric modulus of porous piezoceramics on its initial macrodeformations are realized are determined. An analysis of graphs of continuous dependences of the initial and resulting values of the effective piezoelectric modulus on the pore shape parameter is given for various cases of their volumetric content, connectivity and axisymmetric initial deformations of porous piezoceramics.

Branching Markov Chains: Survival Thresholds and Applications to Species Navigation
Authors: Schinazi Rinaldo
Published: August 2024

This manuscript presents a detailed mathematical analysis of survival thresholds in branching Markov chains, with applications to the study of species navigation. We examine conditions under which a species, modeled as a branching Markov chain, can survive constrained on returning to its birth place to give birth. The study demonstrates that survival is possible only when the return probability of an individual to its birth place exceeds 1/2. Our model, extending recent work by Lebensztayn and Pereira, offers new insights into the interplay between survival probability and navigation skills. These findings provide a theoretical framework for understanding evolutionary dynamics in species with varying degrees of navigation skills, explored through mathematical modeling.
Indian National Congress’s Hits and Misses in General Elections 2024
Authors: Rai Praveen
Published: August 2024

The General Elections 2024 miraculously halted the declining political graph of the Indian National Congress and doubled its presence (seats won) in the lower house of parliament since the national hustings in 2019. The strategies implemented for reviving the party, like ‘Bharat Jodo Yatras’ (walkathons led by Rahul Gandhi), had an erratic pan-Indian electoral impact; as a result, it partly reclaimed its lost political space. The mandate failed to reverse the deinstitutionalization process of the grand old party, and its fragmentary legitimization seems to be by default rather than design. It failed to register a win and make a comeback primarily due to the absence of party offices in several states and hesitancy in overhauling the Congress system. The way ahead for revivification includes tweaking its archaic ideology, designing a populist model of governance, promoting subaltern leadership, creating a perennial connectivity with citizens, embracing digitalized politicking, and practising aspiration-centric developmental politics.

This study aims to compare the yield and quality of Teak wood from a Forest Industry Organization (FIO) plantation and a private teak plantation (PTP) in Thailand to provide guidelines for the sustainable utilization of teak wood. To quantify yields, we employed a randomized design at two locations (FIO and PTP), and determined volumetric proportions, the yields of milled teak and wood properties. We found that the whole lumber yield differed significantly (p≤0.05) between the two locations, although the yield of lumber sheets did not differ (p>0.05). While more teak wood was produced at the FIO plantation than the PTP, the sawing techniques used at the two locations resulted in no significant difference in wood yield. Wood drying had significantly different effects (p≤0.05) between the two locations, but the drying method did not differ (p>0.05). Overall, the lumber yields were greater for timber harvested from an FIO plantation than a PTP. Even though there are differences in sawing techniques adopted, the final lumber yield did not differ significantly between these two sources. The mechanical properties of teak wood improved with kiln drying, FIO plantation exhibits better properties than dried wood from the PTP.

Background: Benzodiazepines (BZDs) are a class of depressant drugs that have enjoyed widespread use in conventional clinical management of anxiety-related conditions such as panic disorders that require therapeutic central relaxation and sedation. Meanwhile, prolonged administration of benzodiazepines even at low doses has however been linked to variety of undesirable effects such as discontinuation relapse with the associated risk of abuse and dependency. Aim: This study investigated the behavioral, histological and biochemical outcomes of long-term low dose diazepam use and explored the potential role of nigella sativa oil (NSO) in the amelioration of the associated side effects. Methods: Adult Wistar rats (n=32) were randomized into four groups that received normal saline; diazepam; diazepam + NSO; or NSO only, respectively for 14 days. At the end of the period of the various exposures, the rats were taken through behavioral paradigms after which they were sacrificed for chemical and histological profiling. Results: diazepam-exposed rats exhibited stress-related manifestations with relatively poor performance in memory-related tasks. Repeated diazepam ingestion reduced brain antioxidant biomarkers while causing elevation of brain oxidative stress markers. On histological observation, mild degenerative changes were evident in the various brain regions of the diazepam-exposed rats. Conclusion: Interventional nigella sativa oil administration showed therapeutic potentials by mitigating and reversing the observed effects of diazepam, largely due to its antioxidant and anti-inflammatory effects as observed in the present study.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has undergone multiple mutations, leading to the development of various variants.
Objective: To identify the genetic mutations associated with the transmission and virulence of SARS-CoV-2 variants in Indonesia and to examine their correlation with the outbreak timeline.
Methods: We analyzed whole genome sequences of SARS-CoV-2 wild type and variants isolated from Indonesian samples, sourced from GenBank and the GISAID EpiCoV database. The spike glycoprotein gene sequences were examined using the BLAST to identify nucleotide and amino acid changes. Additionally, we investigated the prevalence of these variants and their submission timelines on the GISAID database, correlating them with the outbreak timeline.
Results: Our analysis identified nine amino acid changes in the alpha, beta, and delta variants, and three in the gamma variant, compared to the wild type. A correlation between the submission timelines of SARS-CoV-2 variants and the outbreak timeline indicated that the delta variant (B.1.617.2) likely contributed to the surge in COVID-19 cases from July to September 2021.
Conclusion: Mutations were detected in each variant, emerging at distinct times, and are likely to influence transmission rates and virulence.
