Эзотерический подход к экспликации понятий страдания, объективированной воли (эго) и имманентной целенаправленности с позиции концептуальной идеи об эволюционной каузальной финалистичности

This study endeavors to explicate and elucidate, from an esoteric perspective, the potential, prospective, and functional content of such phenomena as suffering, objectified will (with the ego representing the referent of the psychic structure of the subject), and immanent teleology. Drawing upon the philosophical perspectives on suffering and objectified will by German philosopher A. Schopenhauer, as well as referencing the esoteric teachings of American philosopher-mystic F. Merrell-Wolff, the philosophical views on human existence by J.-P. Sartre, the spiritual concepts of Canadian psychologist E. Tolle, and the arguments posited by Aristotle in favor of the existence of a final cause, the study aims to analyze these phenomena. An attempt is made to demonstrate the interconnectedness between the claims of the objectified will, as discussed in philosophical discourse, and the ideas of theoretical physicist S. Hawking in the field of physical sciences, particularly in the evolutionary development of the universe. Through the discourse, immanent teleology, manifested in life itself as an inclination towards eternal peace, is asserted as an a priori form of understanding the world of phenomenal spatiotemporal multiplicity. In contrast, the objectified will strives for the identity of infinite energy density through possession, sole proprietary ownership, and governance over the objects of the universe. These dual directions culminate in liberation through the overcoming or destruction of enslavement, ultimately leading to the annulment of time and space.

Bullen-Mercer type inequalities with applications in numerical analysis

In mathematical analysis theory of inequalities has considerable influence due to its massive utility in various fields of physical sciences. These are investigated via multiple approaches to acquire more precise and rectified forms of already celebrated consequences. Integral inequalities are investigated to compute the error bounds for quadrature schemes. Among all of them, one is Hermite-Hadamard inequality, which has mighty efficacy. Numerous generalizations have been proposed in the literature based on different novel and innovative procedures. In recent years, Bullen inequality has been very commonly studied inequality. The main objective of our progressive study is to establish a new set of Bullen-type inequalities concerning the Jensen-Mecer inequality. For the completion of the current investigation, we derive a new general Bullen-Mecer equality, which is beneficial to achieve our primary consequences. Furthermore, Considering the Bullen-Mecer equation, we employ the convexity property together with famous Hölder's type and Young's inequalities, bounding, and Lipschitz characteristics of functions to conclude new variants of generalized upper bounds of Bullen inequality. Also, we deliver some applications of outcomes to means, special functions, error bounds, and iterative methods to solve non-linear problems. Lastly, we verify our findings through various simulations. The advantage of the current study is that several results concerning Bullen's inequality can be retrieved from our proposed results and various new results can be achieved by choosing the values for γ and δ. By utilizing the similar technique that we have adopted new iterative schemes can be established from integral inequalities.

Application of conserved quantities using the formal Lagrangian of a nonlinear integro partial differential equation through optimal system of one-dimensional subalgebras in physics and engineering

Abstract This research article analytically investigates a soliton equation of high dimensions, particularly with applications, and precisely in the fields of physical sciences and engineering. The soliton equation of high dimensions, particularly with applications, and precisely in the fields of physical sciences along with engineering, is examined with a view to securing various pertinent results of interest. For the first time, the conserved currents of an integrodifferential equation (especially those of higher dimensions) are calculated using a detailed optimal system of one-dimensional subalgebras. Infinitesimal generators of diverse structures ascribed to Lie point symmetries of the understudy model are first calculated via Lie group analysis technique. Additionally, we construct various commutations along Lie-adjoint representation tables connected to the nine-dimensional Lie algebra achieved. Further to that, detailed and comprehensive computation of the optimal system of one-dimensional subalgebras linked to the algebra is also unveiled for the under-investigated model. This, in consequence, engenders the calculation of abundant conserved currents for the soliton equation through Ibragimov’s conserved vector theorem by utilizing its formal Lagrangian. Later, the applications of our results are highlighted.

The proposed technique is examined on a variety of problems and the obtained results are presented both quantitatively in tables and visually in figures. Additionally, a comparative analysis is conducted between the numerical outcomes of the proposed technique with previously published methods to validate the correctness and accuracy of the current approach. The primary objective of this research is to investigate the application of subdivision schemes in the fields of physical sciences and engineering. Our approach involves transforming the problem into a set of algebraic equations.

Use of Computer Technology in Research

Due to the infinite capabilities of the computer, it can be called a miracle. As a result of the development of fast working electronic digital computers and their use in various fields, a new revolution has been initiated in all the fields of knowledge and science. Due to computers, there has been a very significant and meaningful change in the thinking, working style and effectiveness of humans. Research work done in various fields is also not untouched by the influence of computers. The use of computers has affected not only the research work done in the field of physical sciences but also in the field of social sciences. The availability of computer facilities has had a special impact on two most important dimensions of research work in social and behavioral sciences. First, computers have made the preparation and presentation of research reports more simple and form. Second, computers have made the work of analysis easier and accurate. In fact, as a result of computers working at very fast speed, there has been significant development in the field of data storage, processing and analysis. As a result of computers, the problem of complexity of statistical calculation tasks has ended. Computers have made it possible to do calculation work of years in months, calculation work of months in days, calculation work of days in minutes and calculation work of minutes in seconds. Many such research works, which were not possible earlier due to the complex complexity of calculations used in data analysis and excessive timeconsumption, can be easily done today due to the availability of fast calculation facility on computers. The use of computers in research is increasing day by day. Its use in research is increasing day by day due to many reasons. Firstly, all those big calculations can be done easily and quickly in a computer today which was either never possible earlier or there was a possibility of some error if done by the human brain. Therefore, first of all, because of the ease with which the computer can calculate quantitative facts, it is used in research. The second advantage is that the computer can absorb a lot of quantitative or explanatory facts without demanding much space and presents them in the blink of an eye. It becomes very easy to send facts because they can be easily taken out as a second copy by the computer.

Mapping Two Decades of Research Productivity in the Middle Eastern and Arab Countries: A Comprehensive Bibliometric Analysis

Middle Eastern and Arab countries have been experiencing significant advancements in scientific research and development over the past few decades. Understanding the trends, patterns, and impact of research within this region can provide valuable insights into its scientific landscape, identify areas of strength, and uncover potential areas for improvement. This study presents a comprehensive bibliometric analysis of research productivity in the Middle Eastern and Arab region over a 20-year period. The findings revealed a consistent increase in research productivity, yet mapped significant disparities between countries in scholarly output, excellence, and impact. Adjusting for population size and GDP, Iran displayed the highest publication activity, trailed by Egypt and Turkey. Delving into the distribution of research output across different journal quartiles, the results revealed that this region has a lower percentage of scholarly output published in high-impact journals (both the top 10% and the top 25% categories). Compared to North America and the European Union, the Middle Eastern and Arab region consistently exhibited lower performance in terms of top 10% citations, average citations per publication, and field-weighted citation impact. The field of physical sciences took the lead as the most prevalent subject area in the Middle Eastern and Arab region, comprising about 60.5% of the research emphasis. Conversely, social sciences garnered comparatively less research attention, making up approximately 8.9% of the focus. The region showed strong international collaboration levels (40.5%), yet relatively low national (24.4%) and academic–corporate collaborations (1.5%). The outcomes of this study can facilitate international comparisons and benchmarking, allowing Middle Eastern and Arab countries to position themselves within the global scientific community. There remains a need to prioritize quality over quantity by emphasizing rigorous research practices and collaboration. An ongoing evaluation of research performance using a combination of indicators can help track progress and adjust strategies as needed.

Effect of bulky anions on the liquid-liquid phase transition in phosphonium ionic liquids: Ambient and high-pressure dielectric studies

Although the first-order liquid–liquid phase transition (LLT) has been reported to exist in various systems (i.e., phosphorus, silicon, water, triphenyl phosphite, etc.), it is still one of the most challenging problems in the field of physical science. Recently, we found that this phenomenon occurs in the family of trihexyl(tetradecyl)phosphonium [P666,14]+ based ionic liquids (ILs) with different anions (Wojnarowska et al in Nat Commun 13:1342, 2022). To understand the molecular structure–property relationships governing LLT, herein, we examine ion dynamics of two other quaternary phosphonium ILs containing long alkyl chains in cation and anion. We found that IL with the anion containing branched –O–(CH2)5–CH3 side chains does not reveal any signs of LLT, while IL with shorter alkyl chains in the anion brings a hidden LLT, i.e., it overlaps with the liquid-glass transition. Ambient pressure dielectric and viscosity measurements revealed a peculiar behavior of ion dynamics near Tg for IL with hidden LLT. Moreover, high-pressure studies have shown that IL with hidden LLT has relatively strong pressure sensitivity compared to the one without first-order phase transition. At the same time, the former exposes the inflection point indicating the concave-convex character of logτσ(P) dependences.

Remote Lab Experiments in Mechanic: The Compound Pendulum

In the teaching of experimental sciences, practical work plays a crucial role since it allows learners to transfer the knowledge acquired in theoretical courses into practical skills. For this purpose, laboratories allow learning by experience and aim at involving students, which reinforces learning receptivity. Recent years have seen an increasing use of online labs, including both virtual and remote labs, Remote labs, providing online interfaces to physical labs, allow students to conduct experiments with real-world equipment anywhere and at any time. This paper proposes a model of design, development and implementation of a remote manipulation in an E-Lab. It is the compound pendulum which is part of the handling offered to the students of the 1st year of university in the field of physical sciences. The aim of this paper is to make this approach available to allow more experiments on a digital platform in order to allow learning for all, independently of time and place.

Backward Degree a new index for online and offline change point detection based on complex network analysis

How to identify an upcoming transition in a time series continues to be an important open research issue. In various fields of physical sciences, engineering, finance and neuroscience abrupt changes can occur unexpectedly and are difficult to manage during the temporal evolution of the dynamic system. In this work, we developed a new unsupervised method called “Backward Degree” based on a new topological graph index that we introduce, which can be used to detect not only offline point of change, but also can effectively be used as an early warning system for online detection of upcoming abrupt changes. Specifically, based on the well-established algorithm “Visibility graph”, which was introduced by Lacasa et al. (2008) we convert a time series into a complex network and then we apply our proposed approach. The results, on a number of synthetic and financial datasets demonstrate that the proposed methodology correctly identifies change points during the evolution of time series validating the advantages of the proposed methodology for effective detection an upcoming abrupt transitions.

Trait Stereotypes of Scientists as Analytical and Cold Align With Perceptions of Men More Than Women on Both Implicit and Explicit Measures

Previous work using implicit tasks has demonstrated associations at a categorical level between men and science-related words (e.g., chemistry, physics, engineering). The current research explores trait attributes, examining the overlap in trait stereotypes of scientists with trait stereotypes of men and women, using both implicit and explicit stereotyping measures. Study 1 identified traits stereotypically associated with scientists along the analytic and cold dimensions, and counterstereotypic traits on unquestioning and warm dimensions. Study 2 demonstrated strong gender-scientist stereotypes on both explicit and implicit measures such that men were seen as more analytic and cold and less unquestioning and warm than women. Although robust effects were observed on both types of measures, their correlation was weak and nonsignificant. The misfit between trait perceptions of scientists and women, whether measured implicitly or explicitly, suggests trait stereotypes help maintain the gender imbalance in physical science fields.

Solving phase retrieval with random initial guess is nearly as good as by spectral initialization

The problem of recovering a signal x∈Rn from a set of magnitude measurements yi=|〈ai,x〉|,i=1,…,m is referred as phase retrieval, which has many applications in fields of physical sciences and engineering. In this paper we show that the smoothed amplitude flow based model for phase retrieval has benign geometric structure under the optimal sampling complexity. In particular, we show that when the measurements ai∈Rn are Gaussian random vectors and the number of measurements m≥Cn, our smoothed amplitude flow based model has no spurious local minimizers with high probability, i.e., the target solution x is the unique global minimizer (up to a global phase) and the loss function has a negative directional curvature around each saddle point. Due to this benign geometric landscape, the phase retrieval problem can be solved by the gradient descent algorithms without spectral initialization. Numerical experiments show that the gradient descent algorithm with random initialization performs well even comparing with state-of-the-art algorithms with spectral initialization in empirical success rate and convergence speed.

Interfacial adsorption of nanoparticles of maltodextrin for enhanced protection of metal surface

In recent years, application of nanoparticles in various fields of physical science and natural science receiving tremendous attention from researchers. Nanoparticles can offer significant advantages in terms of high stability, enhanced mechanical properties, and high surface area to volume ratio. This work attempts to explore these noble characteristic properties of nanoparticles for preservation for materials of engineering applications. Nanoparticles of maltodextrin (MLD-Np) were prepared by microwave-mediated nanoprecipitation technique. Characterization was done by spectral, zeta potential measurement, X-ray studies, Scanning Electron Microscope (SEM) and Transmission Electron Microscopy (TEM) analysis. In the second part, these nanoparticles were tested for their surface protection ability due to interfacial adsorption. Corrosion inhibition study measurements were done by electrochemical methods, and interfacial adsorption of inhibitor was established by studying surface morphology. The efficacy of these nanoparticles was 93% for the addition of 50 ppm of it. In the last part of this work, an attempt is made to compare the inhibiting ability of various reported chemical inhibitors for acid corrosion of zinc with synthesized nanoparticles. Nanoparticles of maltodextrin emerged as an appreciably good green corrosion inhibitor with environmental and economic benefits.

Preface

It is well known that the physical sciences and data processing are not only helpful in all fields of science and technology, but also contribute to the improvement of the quality of human life to a large extent. Thus, more and more scholars focus on physical sciences and data processing. It is obvious that the related fields have become the frontier and hot topic of scientific research. In this context, it is urgent to build an academic exchange platform to promote the sharing of research results and theoretical exchanges in related research fields. Therefore, the International Conference on Advances in Physical Sciences and Data Processing comes into being.APSDP 2020 is held at the Qingdao, China in Video presentation mode on 31st December 2020, which is sponsored by Shandong University(at Qingdao) and Qingdao University. It aims to promote integration and innovation in the fields of physical sciences and data processing and provide researchers, policymakers and industry practitioners with an excellent opportunity to exchange ideas, technologies and related applications, and share successful experiences and the latest research results.The global outbreak of COVID-19 in 2020 poses a serious threat to social and economic development, cultural exchanges and people’s lives and health. Governments around the world have taken active and effective measures to prevent the spread of the epidemic, such as international traffic control, keeping social distancing, wearing masks at all times, and so on, which have effectively prevented the spread of COVID-19 but to a certain extent affected international academic exchanges. How to realize academic exchanges while ensuring the life and health safety of participants has become a problem that we must solve. In any case, life and health always come first. With the help of the development of network technology, we have decided to hold this conference in a video presentation way rather than physical face-to-face, which not only realizes the purpose of academic exchange, but also reduces the risk of the spread of the epidemic. Our decision is praised unanimously by the participants and this online conference has achieved great results.We have received a total of more than 40 contributions. Through strict peer review, 14 articles are accepted. Authors whose articles are accepted are required to record 10-15 minutes of video to present their research findings. All videos are uploaded to a web server (Google Drive and Bilibili) where other participants can log in and watch the videos at any time. If they have any questions, they can communicate with the presenters via email. These videos will exist for a long time and people can access to them at any time. By doing so, we not only break the limitation of place and time, but also realize the purpose of communication and learning. More importantly, we can prevent the spread of COVID-19 and ensure the health and safety of the participants.We would like to express our sincere thanks to Prof. Dr. Osman ADIGUZEL for his selfless help in organizing the conference and publishing articles. We would also like to thank all members of the organizing committee for their efforts in organizing this conference under such epidemic spreading circumstances. Thanks to all the peer reviewers for their hard work in controlling the quality of the articles. It is expected that the results of the conference will inspire and help scholars in the field of physics and information processing. APSDP 2021 conference is under active preparation and we look forward to your continued participation.The Conference Committees

The formation of a unified database on physical subjects

Currently, when applying for registration of an invention, to assess the chances of patenting an object, to determine the novelty, it is necessary to review existing patents. Because at the moment there is a large amount of information about patent documents dispersed in various sources, the search time for a particular document significantly increases. This also happens with magazine articles. In this regard, this article is aimed at solving the above problem by creating a single database. To create the database, we used archives with patent documents in XML format, downloaded from the official RUPTO and USPTO websites. Physical profile journal sites were used for processing journal articles. The software module presented in this article is intended for specialists working in the field of physical Sciences. Using this program, you can search for English-language and Russian-language journal articles and RUPTO and USPTO patents on physical subjects, and get links to documents. The program module is developed in the Python programming language using the BeautifulSoup library, as well as the MongoDB.

Ferroic orders in two-dimensional transition/rare-earth metal halides

Since the discovery of graphene, two-dimensional materials with atomic level thickness have rapidly grown to be a prosperous field of physical science with interdisciplinary interest for their fascinating properties and broad applications. Very recently, the experimental observation of ferromagnetism in a Cr2Ge2Te6 bilayer and a CrI3 monolayer opened a door to pursue long-absent intrinsic magnetic orders in two-dimensional materials. Meanwhile, the ferroelectricity was also experimentally found in a SnTe monolayer and CuInP2S6 few layers. The emergence of these ferroic orders in the two-dimensional limit not only brings new challenges to our physical knowledge but also provides more functionalities for potential applications. Among various two-dimensional ferroic ordered materials, transition/rare-earth metal halides and their derivants are very common. In this Research Update, based on transition/rare-earth metal halides, the physics of various ferroic orders in two-dimensional materials will be illustrated. The potential applications based on their magnetic and polar properties will also be discussed.

Lie symmetry analysis and dynamical structures of soliton solutions for the (2 + 1)-dimensional modified CBS equation

In this present article, the new [Formula: see text]-dimensional modified Calogero-Bogoyavlenskii-Schiff (mCBS) equation is studied. Using the Lie group of transformation method, all of the vector fields, commutation table, invariant surface condition, Lie symmetry reductions, infinitesimal generators and explicit solutions are constructed. As we all know, an optimal system contains constructively important information about the various types of exact solutions and it also offers clear understandings into the exact solutions and its features. The symmetry reductions of [Formula: see text]-dimensional mCBS equation is derived from an optimal system of one-dimensional subalgebra of the Lie invariance algebra. Then, the mCBS equation can further be reduced into a number of nonlinear ODEs. The generated explicit solutions have different wave structures of solitons and they are analyzed graphically and physically in order to exhibit their dynamical behavior through 3D, 2D-shapes and respective contour plots. All the produced solutions are definitely new and totally different from the earlier study of the Manukure and Zhou (Int. J. Mod. Phys. B 33, (2019)). Some of these solutions are demonstrated by the means of solitary wave profiles like traveling wave, multi-solitons, doubly solitons, parabolic waves and singular soliton. The calculations show that this Lie symmetry method is highly powerful, productive and useful to study analytically other nonlinear evolution equations in acoustics physics, plasma physics, fluid dynamics, mathematical biology, mathematical physics and many other related fields of physical sciences.
