THE PROBLEM OF EMOTIONALITY IN THE EDUCATION OF PERFORMERS-VOCALISTS: IN SEARCH OF BALANCE AND HARMONY
Authors:   Moscow State Tchaikovsky Conservatory, Moscow, 125009, Russian Federation, Kovaleva (Abzalova) Svetlana R.
Published: September 2024

Along with many technical tasks, the student and his or her teacher usually face the problem of understanding and adequately reflecting the content of a musical work, which requires a special emotional approach. Emotional lability and self-regulation are extremely important for the performer also because of the need for free and natural behavior on stage. In the matter of emotionality, any performer and especially a vocalist needs to find a balance, since both insufficient and excessive expression of emotions are unacceptable in professional art. Exploring the underlying causes of this phenomenon, the author of the article gives practical recommendations for overcoming both inexpressive and deliberately emotional performance. One of the author’s key ideas is to understand the need to develop a singer-vocalist as a multifaceted personality, interested in studying not only different types of art, but also various spheres of life. Some of the author’s important tips include practicing acting, setting several “super-tasks” while working on a piece, watching, and participating in master classes of outstanding teachers and artists, comparing different vocal interpretations, analysing one’s own recordings, etc. Most of the success depends on how the teacher builds contact with the student, and how much the mentor can support and inspire his or her mentee. The materials in the article can be useful to both vocal teachers and students at music colleges and universities.

The term “scenography” is now widely used throughout the world. In recent years, it is in demand not only in the theatre sphere, but is used in relation to exhibition projects, concerts, shows and other events. However, it has no generally accepted definition and has multiple meanings. The desire to identify the causes of this phenomenon is the basis for the research; the historical-genetic method was chosen as the main research tool. The article examines the evolution of the term “scenography” in the context of the theatre art development. The role and functions of the artist in the creation of a performance have changed in different historical periods, which was reflected in terminology. In the XXth century, the ancient Greek word “scenography” found a new life due to powerful creative reforms in theatre art. Gradually it went beyond its narrow initial definition and began to be widely used by theorists, practitioners and critics in various meanings. This process continues today. Considering the diversity of artistic forms and approaches in contemporary art, this trend requires careful understanding and reflection in the theory of scenography and improvement of the terminological apparatus. The material of the article is relevant for researchers, critics and practitioners of theatre art and related fields of activity.
CHINESE CONDUCTOR CAO PENG: YEARS OF STUDY AT THE MOSCOW CONSERVATORY (based on archival materials)
Authors:   Russian State Specialized Academy of Arts, Moscow, 121165, Russian Federation, Jiafeng Tian
Published: September 2024

This article examines the period of study of the outstanding Chinese conductor Cao Peng at the Moscow Conservatory. The documentary base allows to introduce into scientific use new material unknown to date in both Chinese and Russian musicology. The archival sources of educational institutions are attributed as universal resources of authentic materials important both for historical context and for assessing the stages of professional development of undergraduate and postgraduate music students. As universal keepers of history, archives are of exceptional value, surpassing the value of other sources. The article analyses a set of documents from Cao Peng’s personal file, including autobiographical information. By the time he entered the Moscow Conservatory, Cao Peng already had considerable experience as a conductor in leading Chinese creative collectives, which gave him an advantage over other Chinese applicants for admission to the Conservatory. The analysis of documents from Cao Peng’s personal file made it possible to gradually reconstruct the course of the conductor-symphonist’s studies in his homeland and at the Moscow Conservatory in the class of Professor L. Ginzburg.
REFRACTION OF MUSICAL TRADITIONS OF ANCIENT CULTURES IN THE WORK OF ANDRÉ JOLIVET (on the example of “The Song of Linos” for flute and piano)
Authors:   Moscow Pedagogical State University (MPGU), Moscow, 119991, Russian Federation, Chistyakov Roman V.
Published: September 2024

This article is devoted to the early work of the French composer André Jolivet, which harmoniously combines the traditions of different cultures. It is primarily an interaction of Eastern and African traditions based on the rhythmic component and modality, as well as trends of French music of the first half of the twentieth century in all their diversity — from the impressionism of C. Debussy and M. Ravel to modernism and avant-garde. This material examines in detail the composer’s central work “The Song of Linos” for flute and piano, created on the border of the early and mature periods of creativity, in which the interweaving of traditions is considered in the context of technical methods and means of sound representation in playing wind instruments. André Jolivet, as did Olivier Messiaen, was a member of the Young France group of French composers. Unlike Olivier Messiaen, who always looked towards God and Heaven in his music, A. Jolivet strove to reveal the diversity of human passions through the prism of the mystical essence of music. The main aspiration of A. Jolivet was to return music to its ancient meaning — the magical beginning that unites people. Thanks to A. Jolivet, the artistic horizons of musical performance and pedagogy were significantly expanded, including the growth of the technical level of performers and the emergence of new performance techniques.

A study of gestures representing musical emotions
Authors: Sun Yuwen , Mazzola Guerino
Published: September 2024

The creation of music has originated from the burst of inspiration of the composer. Many studies suggested that improvisation plays a more vital role than composition in the emergence of new forms of music. The production of music, especially in Western cultures, tends to follow its traditional music theory. With the emergence of Pythagorean music theory, Western musicology has been defined and developed in depth. The composer’s creation is based on music creation within the framework of the Western music theory. However, in recent years, with the rise of the topic of music gestures, some scholars have learned that music ontology as a four-dimensional hypercube is inseparable from the performer’s gesture. Therefore, some musicians also attempt to create flexible music from the perspective of music performers and based on performance gestures. This kind of music creation breaks the traditional music theory system and has more personal style characteristics, but few people can understand the thinking logic behind this kind of creative behavior. Therefore, this article focuses on the singing gesture and reversely analyzes its impact on musical creation. We use a recent mathematic definition of gestures and we discuss emotion from its etymological origin (from the Latin e-movere) as a gestural movement from inside out. This article conducts an in-depth analysis based on the singer’s gesture for the following two reasons: First, the literature on the connection between singing gesture theory and composition theory remains scarce. Second, gestures produced by a singer are the only performance form that is not enabled by other instruments.

Published: September 2024

The exact etiologies of most neurodegenerative disorders remain poorly understood, therefore hampering the identification of molecular targets with clinical therapeutic potential. Recent clinical and experimental evidence supports the notion that amino acid metabolism could be implicated in the pathophysiology and disease progression of neurodegenerative diseases. This review aims to present the most common neurological diseases that lead to axonal degeneration and to examine the potential role of amino acid metabolism, with a particular focus on multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis. The primary objective of this study is to identify potential amino acid biomarkers through metabolomics research and to propose therapeutic approaches by modulating amino acid-sensing signaling pathways to effectively monitor disease progression in neurodegenerative disorders. In this context, two distinct cellular signaling pathways are examined: the mechanistic target of rapamycin signaling pathway and the general control non-derepressible protein-integrated stress response pathway. These signaling cascades are analyzed in relation to each of the aforementioned neurological disorders to identify their potential regulatory roles in disease progression and pathophysiology. The review concludes by considering emerging amino acid biomarkers with potential clinical and diagnostic value, exploring signaling cascades for therapeutic manipulation to improve clinical outcomes in neurodegeneration, and providing insights for future research in the biomedical field.

Published: September 2024

Neurogenesis plays a major role in neuroplasticity and memory. In adult human and mouse brains, neural stem cells (NSCs) are mainly distributed in two extensively characterized neurogenic niches: the subgranular zone (SGZ) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles. Impaired neurogenesis is one of the consequences of Alzheimer’s disease (AD), contributing to cognitive decline and progressive memory loss. Developing new in vitro models that resemble this three-dimensional (3D) structure is fundamental for enhancing our understanding of the SVZ neurogenic niche dynamics in AD. Herein, we produced and characterized a 3D-bioprinted model of the adult SVZ neurogenic niche containing amyloid β (Aβ) oligomers, mimicking the NSC microenvironment in AD. In this model, Aβ oligomers induce oxidative stress and reduce the proliferative potential of NSCs, while stimulating neuronal differentiation. We hypothesize that these events are an early attempt of adult NSCs to compensate for neuronal death in AD pathogenesis. Our 3D model simulates the NSC niche physiology, reproducing an early response of NSCs in AD, strengthening the importance of studying the potential of neurogenesis in neurodegeneration.

DESIGN FEATURES OF GRAIN HARVESTING COMBINEERS CASE IH "AXIAL-FLOW" SERIES
Authors: YELENYCH Anatoliy
Published: September 2024

Harvesting grain is a very important production process that must be carried out as quickly as possible to obtain high-quality grain. Here it is important that the equipment is adjusted to the structure of the plants, and the plants, in turn, are prepared for machine harvesting. When creating grain harvesting equipment, various factors are taken into account: agrobiological properties and the structure of plant organs, stand height and density, lowness, strength, humidity, size and weight of fruits, weight ratio of grain to non-grain part, stage of maturity and others. Currently, harvesting of grain crops is carried out by direct or separate combining. Direct involves performing several operations: cutting plants, threshing plant mass, separating grain from straw, cleaning grain from various impurities, as well as harvesting grain and non-grain part of the crop. It is important that the harvester performs these processes at the same time in the stage of full maturity of the grain. This harvesting method is suitable for bread mass that is not clogged and has ripened evenly. As for separate combining, here mowing of plants and their threshing are carried out separately.
Providing the enterprise with high-performance harvesters and the level of their use significantly affect the gross harvest of agricultural crops. In case of violation of the calendar terms for harvesting grain crops by more than 10–12 days, grain losses can reach 25–30%. In order for such a situation not to arise, agricultural enterprises must have the required number of harvesters of the necessary capacity, which could ensure, in the optimal time, harvesting of agricultural crops.
In order to give preference to one or another combine harvester model, you need to know not only its price, but also individual technical and economic characteristics and the cost of threshing a ton of harvest. Because this indicator reflects the cost of the harvester, operating costs, its productivity, reliability and cost of spare parts.
Innovation is only accelerating. Over the past 20 years, the average productivity of self-propelled grain harvesters has increased almost four to five times. The level of computerization of mechanized operating technologies also increased.
The demand for products of the grain sub-complex is only growing. Ukraine is dominated by a diverse fleet of industrial grain harvesters of foreign production, purchased both new and used, the use of these grain transport systems is expedient and relevant. The question of choosing a modern high-performance grain harvester and the question of its effective use remain relevant.

Authors: TOKARCHUK Oleksii , TOKARCHUK Dina , MYTKO Mykola , BAHRII Vladyslav
Published: September 2024

The use of alternative energy sources, such as solar, wind, hydropower, etc., can reduce dependence on traditional energy sources, which are unstable and limited. This can help solve the problem of energy shortages and reduce the risk of energy crises.
The article provides an overview of modern innovative technologies in the field of production, operation, and recycling of solar panel systems.
Photovoltaic technologies have a long history of development and refinement, as from their inception, they were relatively large, costly, and inefficient systems. However, over the years, scientists and engineers, recognizing the extraordinary importance of renewable systems, have worked on comprehensive improvement and modernization of these technologies. Today, modern panels are capable of achieving an efficiency ratio of around 20%. Panels have gradually become more accessible to people, their application in various sectors has increased, and now solar energy systems are used both for energy generation for sale and for the self-consumption of homeowners or factories.
The article primarily examines modern materials for the photovoltaic elements of panels, their advantages and disadvantages, and application peculiarities. Various innovative approaches and panel enclosure materials are considered to ensure the strength and lightness of solar systems.
Additionally, perovskite solar panels are discussed in detail, along with the prospects of their industrial-scale application. Given that like any technology, solar panels have a limited lifespan, approaches to panel recycling after their operational life are also considered.
Finally, the article addresses the application of innovative technologies in the field of renewable energy sources in Ukraine, as many systems will require replacement due to military actions in the south and east of the country.
RESULTS OF ANALYTICAL RESEARCH OF THE SEED PROCESSOR OF THE IMPROVED SOWING SECTION OF THE PNEUMATIC SEEDER
Authors: ALIIEV Elchyn , BEZVERKHNII Petro , ALIIEVA Olha
Published: September 2024

According to preliminary research, the primary factor influencing the accuracy of seed placement by pneumatic seeders is the process of transferring seeds from the metering device to the point of direct entry into the furrow formed by the coulter in the soil. The first factor is related to the high velocity of the air stream, which increases the risk of seed dislodgement from the seed boot and its placement outside the furrow. This problem can be addressed by installing a seed retarder above the seed boot. The second factor lies in the imperfect shape of the seed channel in the seed boot. Seeder developers, aiming to create an "ideal" seed bed in the soil, often underestimate the importance of the shape of the seed channel. Due to the high speeds at which modern pneumatic seeders operate (1.5–4.2 m/s) and their constant vibration, seeds in the seed channel of the seed boot constantly collide with its walls, leading to changes in direction and speed of movement. This chaotic seed movement results in decreased seeding accuracy. The third factor is the complete absence or incorrect installation of a seed retarder, which should prevent seed dislodgement from the bottom of the furrow.
As a result of the analytical studies, the kinematics of seed motion after ejection from the seed boot and rebound from the furrow bottom and seed retarder were considered. The obtained dependencies include the maximum height of the parabolic seed trajectory y3`, the difference in distance between the points of rebound from the ground surface and the distance traveled by the seeder Δx from the initial seed velocity Vp0, the angle of their ejection α, the height of the seed retarder placement Hu, and the angle of its inclination β. By satisfying the conditions and for the obtained dependencies in Wolfram Cloud, the following rational parameters were obtained: α = 47°, β = 0°, Hu < 0.134 m. To ensure consistent seed placement at the center of the furrow bottom after rebounding from the seed retarder with a slight trajectory deviation (± 0.01 m), the profile shape of its working surface should be parabolic with the focus at point pf = 0.134 m.

Authors: Francica Giampiero
Published: September 2024

Aim: This study aimed to evaluate the utility of the combined use of contrast-enhanced ultrasound (CEUS) and intracavitary CEUS (IC-CEUS) with diluted SonoVue in the management of percutaneous treatment for pyogenic liver abscess (PLA). Methods: 36 patients (23 males, 13 females; mean age 64 ± 13.9 years) with 39 PLAs (mean size 7.6 ± 3.4 cm) were selected for percutaneous catheter drainage (PCD) and/or percutaneous needle aspiration (PNA). CEUS and IC-CEUS were employed during the interventional maneuver and follow-up during hospital stay in all cases. Results: 33 patients with 24 PLAs underwent PCD, 8 patients with 10 PLAs were treated with single or multiple PNA, and the combination of PCD and PNA was used in the remaining 5 cases. During the treatment planning phase, the combined use of CEUS and IC-CEUS affected therapeutic choices (e.g., drainage technique, additional therapeutic measures) in comparison with pre-operative imaging in 66.7% of patients. Throughout the follow-up period, CEUS and IC-CEUS facilitated monitoring of PLA evolution, providing crucial information, especially with IC-CEUS, on the optimal timing of catheter removal. No adverse events occurred after CEUS and IC-CEUS. Conclusions: The combination of CEUS and IC-CEUS proved to be a powerful and safe tool for tailoring US-guided percutaneous treatments to patients with PLA.

Injuries at the Work Place: An Examination of the Basis for Claim Under Nigeria’s Employees Compensation Act (ECA) 2010
Authors: Usman Musa Binyaminu
Published: September 2024

The Employer employee relationship has been in existence since the time immemorial, Master servant relationship was initially practiced up to the time where such relationship was abolished, which was replaced with an institutionalized relation i.e. Employer employee relations, where each of the parties has his own rights and duties spelt out by the Laws establishing and guiding their relationship. In most cases during the course of this relationship, parties may sustain an injury of different degrees, ranging from partial or permanent disabilities, at some instances to the extent of even loss of life in the course of that employment, depending on the nature of the employment. This work will explore the available statutes ranging from the International treaties which Nigeria happened to be a signatory to, and the other Nigerian legislations, and Case Laws regulating the Employee employer relationship with a view to examining  such injuries based on their compensability and what will qualify them to be so i.e. the basis for the claim of damages based on the injuries sustained under the Employee’s Compensation Act 2010, and also to examine how such claims could be made appropriately in accordance with the law.  At the end of this work, the Employer and employee would be better educated in the nature of the injuries that attracts compensation as well as what qualified them to be so, and how it could be done in accordance with the law
The Role Played by Celebrities in the Promotion of Goods and Services in Cameroon
Authors: Fuh Ngonjo Victor
Published: September 2024

Advertisers in Cameroon at the local and national level always make use of celebrities in their adverts so as to win the hearts of their potential customers. This form of promoting goods and services is visible on television and radio especially during some special programs organised by some radio and television houses such as ‘‘Equinoxe Soir’’ (Equinox Evening). Furthermore, most streets in Cameroon are coloured with billboard posters carrying the images of Cameroonian celebrities from the music, football and the entertainment industry advertising the products or services of companies such as MTN and Orange Cameroon just to name but these. This paper looks at types of celebrities used by marketers in Cameroon in the promotion of their goods or services, why Cameroonians use celebrities in their adverts and the advantages of using them in the promotion of their goods. The paper further explores the role they play in the promotion of goods and services on billboard posters. This study was conducted by using descriptive qualitative method. Random sampling technique was used to collect the sample of data from billboards posters (2022-2023). Furthermore, data was also culled from some television programs such as Equinox Evening. Source credibility theory was used to analyse the collected data. The analysis reveals that three types of celebrities are used by Cameroonians in their adverts. These celebrities are from the music, football and the entertainment industries. In addition, Cameroonians use celebrities in their adverts to attract the attention of the target audience as well as influence customers’ views of a product. The advantages of using celebrities by Cameroonians in their adverts is that it positions the brand in the minds of the target audience. More so, it attracts new users as well as breathe life into a failing brand. These celebrities play an enormous role in the marketing of goods and services in that, they invite the public to join them consume the goods or services they are seen promoting. This gesture makes the messages on these adverts to be credible. The credibility of these messages also makes the public to believe in what they say; thus an increase in sales.

La epilepsia postraumática (EPT) es una de las consecuencias de red a largo plazo más devastadoras de la lesión cerebral traumática (LCT). Actualmente no existe un tratamiento aprobado que pueda prevenir la aparición de convulsiones espontáneas asociadas con una lesión cerebral, y muchos casos de EPT son refractarios a los medicamentos anticonvulsivos. La epileptogénesis postraumática es un proceso duradero por el cual un cerebro normal exhibe excitabilidad hipersincrónica después de un incidente de lesión en la cabeza. Comprender las redes neuronales y las patologías moleculares involucradas en la epileptogénesis es clave para prevenir su desarrollo o modificar la progresión de la enfermedad. En este artículo, describimos una evaluación crítica del estado actual de la investigación de la EPT con énfasis en modelos experimentales, mecanismos moleculares de la epileptogénesis postraumática, biomarcadores potenciales, y la carga de comorbilidades asociadas al EPT. El objetivo de la investigación de la epilepsia es identificar nuevas estrategias terapéuticas que puedan prevenir el desarrollo de EPT o interrumpir el proceso epileptógeno y aliviar las comorbilidades neuropsiquiátricas asociadas. Por lo tanto, también describimos los datos preclínicos y clínicos actuales sobre el tratamiento de las secuelas del EPT. Las diferencias en los patrones de lesión, el período de latencia y los biomarcadores se describen en el contexto de la validación del modelo animal, la fisiopatología, la frecuencia de las convulsiones y el comportamiento. Mejorar la recuperación de LCT y prevenir la aparición de convulsiones son tareas complejas y desafiantes; sin embargo, se ha avanzado mucho en esta década demostrando estrategias modificadoras de la enfermedad, antiinflamatorias y neuroprotectoras, lo que sugiere que este objetivo es pragmático. Nuestra comprensión de PTE está en constante evolución.

Published: September 2024

In cybersecurity, the lack of statistical data on cyber-attacks presents a significant challenge from an insurance perspective, hindering the accurate calculation of insurance premiums, furthermore assessing cybersecurity risk exposure and identifying high-risk threat categories. Effective intrusion detection systems (IDS) are paramount in addressing these issues. This research introduces a sophisticated cyber risk assessment model utilizing the Random Forest classification algorithm, tailored explicitly for IDS, and leverages the comprehensive CIC-IDS 2017 dataset. The central objective was to engineer robust models capable of classifying a broad array of cyber threats, focusing on classification accuracy. The model achieved an accurate average classification rate of 96.94% through systematic experimentation and hyperparameter tuning.This study found that 'n_estimators' values of 10 to 300 did not affect cyberattack performance. It was also shown that Bagging and bootstrapping improve model stability by mitigating variance and improving accuracy without many trees. Model performance was high, with an average F1-Score of 97.86%. Cyber-attack statistics are scarce, and from an insurance perspective, the lack of statistical data on cyber-attacks hinders the calculation of insurance premiums. Risk assessment allows for informed self-insurance or risk transfer processes ensuring that policies align with risk management strategies and premium calculations.
An Exponential Map-based Whale Optimization Algorithm (Exp-WOA) for Optimization
Authors: Godbole Vaibhav , Gaikwad Shilpa
Published: September 2024

This research work offers three variations of the Whale Optimization Algorithm (WOA) based on exponential chaotic maps, namely Logistic-Exponential-Logistic WOA (LEL-WOA), Logistic-Exponential-Sinusoidal WOA (LES-WOA), and Logistic-Exponential-Tent WOA (LET-WOA). The WOA with an exponential chaos-based mechanism is developed in this study to overcome the poor rate of convergence of the WOA and to prevent getting caught in local optimal solutions while dealing with the challenges. An exponential chaotic mechanism was employed in this research to initialize the agents and control the parameters of the exploration and exploitation phases of WOA. The proposed methodologies (Exp-WOA) are evaluated using twenty-three widely recognized test functions. The results demonstrate that the given solutions can enhance the performance of WOA by achieving optimal (minimum) values. The findings also indicate that LEL-WOA and LES-WOA exhibit faster convergence than WOA.

Published: September 2024

This paper reports on the design, fabrication, and temperature strain sensing performance of a fiber Bragg grating composite structure for surface mounted temperature measurements over a wide temperature range, with highly reduced strain cross-sensitivity. The fiber Bragg grating sensor is encapsulated in a polyimide tube filled with epoxy resin, forming an arc-shaped cavity. This assembly is then placed between two layers of glass fiber prepreg with a flexible pad in between and cured into shape. Experimental results, supported by finite element simulations, demonstrate an enhanced temperature sensitivity is 26.3 pm/ºC over a wide temperature range of -30℃ to 70℃, and high strain transfer isolation of about 99.65%.

Published: September 2024

Basal implants represent a relatively recent advancement in dental implant technology, providing numerous benefits compared to traditional implant systems. These implants are strategically positioned in the basal bone, which possesses greater density and stability than the conventional jawbone. Specifically designed for fixed rehabilitation in cases of significant jaw atrophy, various designs of basal implants are currently available. This review seeks to detail the characteristics of basal implants and to highlight the distinctions between them and conventional implants.
Robbing the cradle: Factors promoting lecturer-on-student transactional sex relationships at a South African university
Authors: Mutongoza Bonginkosi Hardy , Hendricks Eleanor Alvira
Published: September 2024

While universities have been lauded as sanctuaries of peace where students and staff pursue educational goals, there has been a marked increase in the victimisation of students by staff members who have been known to hound students for sexual favours. This increase in unethical conduct continues regardless of "sound" policies regulating university student and staff relationships. Against this background, this study sought to explore the factors shaping the pervasive practice of transactional sex between staff and students at a university in rural South Africa. Underpinned by the sexual exchange theory, the study utilised an exploratory sequential mixed-methods design. The findings categorised into four key themes—academic reasons, impunity and power dynamics, financial constraints, and peer pressure and influence—highlight the entrenched nature of this practice within the university setting. The study recommended implementing and enforcing strict policies with clear consequences for perpetrators and establishing confidential reporting systems and dedicated support units for victims.
Periodic Coronal Rain Driven by Self-consistent Heating Process in a Radiative Magnetohydrodynamic Simulation

Published: September 2024

The periodic coronal rain and in-phase radiative intensity pulsations have been observed in multiple wavelengths in recent years. However, due to the lack of three-dimensional coronal magnetic fields and thermodynamic data in observations, it remains challenging to quantify the coronal heating rate that drives the mass cycles. In this work, based on the MURaM code, we conduct a three-dimensional radiative magnetohydrodynamic simulation spanning from the convective zone to the corona, where the solar atmosphere is heated self-consistently through dissipation resulting from magnetoconvection. For the first time, we model the periodic coronal rain in an active region. With a high spatial resolution, the simulation well resembles the observational features across different extreme-ultraviolet wavelengths. These include the realistic interweaving coronal loops, periodic coronal rain, and periodic intensity pulsations, with two periods of 3.0 hr and 3.7 hr identified within one loop system. Moreover, the simulation allows for a detailed three-dimensional depiction of coronal rain on small scales, revealing adjacent shower-like rain clumps ∼500 km in width and showcasing their multithermal internal structures. We further reveal that these periodic variations essentially reflect the cyclic energy evolution of the coronal loop under thermal nonequilibrium state. Importantly, as the driver of the mass circulation, the self-consistent coronal heating rate is considerably complex in time and space, with hour-level variations in 1 order of magnitude, minute-level bursts, and varying asymmetry reaching ten times between footpoints. This provides an instructive template for the ad hoc heating function and further enhances our understanding of the coronal heating process.
