Inter-Korea Musical Exchanges and Emotional Politics of Popular Music on the Korean Peninsula
Authors:   The Korean Association for the Study of Popular Music, Kim Hee-sun
Published: December 2023

In the wake of the 2018 Pyeongchang Winter Olympics, inter-Korean musical exchanges featuring reciprocal performances by South and North Korean performing arts troupes resumed after a hiatus of 16 years. Such exchanges began in 1985, serving as peace events affirming ethnic homogeneity and persisted intermittently, subject to interruption by conflict between the two Koreas arising from domestic or international political contexts. However, the 2018 inter-Korea performance deviated from earlier programs of gugak, traditional Korean music from the South and minjok eumak, ethnic music from the North, which had long been highlighted in previous peace events, and instead brought popular music from both sides to the forefront. This change demands closer examination and discussion.
Since 1999, other than events primarily organized by broadcasting companies visiting North Korea, there have been no instances of the complete absence of traditional music, which represents the exclusion of national music in favor of popular music.
This study initially examines the trajectory of South-North Korean musical exchange, then discuss the meaning of ‘ethnic’ music and the collective sentiments of popular music in the context of 21st-century Korean Peninsula Cold War politics, The allocation of meanings relation to ‘ethnicity,’ ‘nation,’ and ‘peace’ to the popular music in the nation-led South-North Korean musical exchange symbolically signifies the position of popular music in the 21st century Korean Peninsula. Consequently, the 2018 musical exchange became an event that both the elevated status of popular music, which had previously occupied a lowest position within the hierarchy of music genres in the 20th century Korean Peninsula, and effectively reflected shifts in attitudes and sentiments toward popular music.
The socio-demographic aspect of the development of the resilience capacity of the socio-economic system in Ukraine
Authors: Ivanyuk Ulyana V.
Published: December 2023

The course and consequences of any shock is uncertain in both space and time. However, the emergence of threats and risks affects all spheres of life of a society in one way or another. At the same time, the socio-demographic sphere is a driver of the resilience capacity of the country’s socio-economic system, and, on the other hand, its qualitative characteristics are the result of the resilience of this system. Continuous regulation and efficient management of socio-demographic processes in society increase the resilience capacity of the country’s socio-economic system in the face of a global shock or threat. Meanwhile, the main public interest is to ensure the safety of each individual and well-being and stability of institutions that guarantee democracy, security, and sustainable development of society. An important indicator of the resilience capacity of Ukraine’s socio-economic system in shocks is the population’s savings. They provide insurance coverage for individuals in case of unforeseen events and contribute to the improvement of living standards. At the same time, rising income and wealth inequality, especially in times of crisis, weakens social resilience by reducing social cohesion in the long run. The socio-demographic resilience of a country can be strengthened or weakened depending on the specifics of a particular shock. The study argues that in the context of crises and threats faced by our country in recent years, the following socio-demographic characteristics weakened the resilience capacity of the socio-economic system of Ukraine the most: unbalanced socio-demographic structure of the society; high level of external and internal migration; a low share of household and business savings in their total income; the illegalization of the economy in general and the labor market in particular, the prevalence of informal employment, low wages and social protection. Today, in the context of the temporal and spatial uncertainty of a full-scale war, it is necessary to continue research on socio-demographic resilience as a strategy, the original cause of the return of people from abroad to Ukraine, and a deterrent to migration from Ukraine in the future. It is a key driver for building the resilience capacity of the country’s socio-economic system and strengthening the proactive position of authorities at various levels on IDP issues, increasing social cohesion, civic engagement, and volunteerism.
Analysis of Inter-state Migrant Workmen
Authors: - HEMAVARSHINI S , - BOWYA DARSHINI K
Published: December 2023

Interstate workmen's mobility is an essential and dynamic feature of India's labor environment. This research gives a succinct review of critical concerns concerning interstate migrant workers. Investigates the reasons for immigration, its job sectors, obstacles, legal safeguards, and contemporary governmental efforts. This study expands on previous research that highlights the complexities and vulnerabilities of this critical workforce. Rural poverty, restricted economic possibilities in their native country, and the promise of higher earnings and living circumstances in destination locations all encourage migrant workers in India. Construction, agriculture, industry, services, and the informal economy are all examples of these.
These workers, however, suffer a number of obstacles, including exploitation, poor earnings, job instability, insufficient living conditions, and restricted access to basic services. Despite legislative safeguards such as the Interstate Migrant Workers (Regulation of Employment and Conditions of Work) Act of 1979, enforcement was patchy, and many workers were uninformed of their rights. This analysis emphasizes the need to collect reliable data and do research to influence policy choices and enhance the lives of interstate migrant workers.

Published: December 2023

Dezavantajlı gruplarla ilgili olarak uluslararası ve ulusal alanda pek çok çalışma yapılmaktadır. Bu grupların içinde yer alan inceleme konularından birisini de kadınlar oluşturmaktadır. Tarih boyunca kadınlara yönelik eşitlik mücadelesi devam etmektedir. Gelinen son noktada gerek sosyal hayatın eşit paylaşımı gerekse kaynaklara erişim noktasında istenilen eşitlik düzeyine ulaşılamamıştır. Cinsiyet eşitliği öğretilerinin başladığı kurumlardan biri ailedir. Sosyalleşilen ilk alan olarak aile, bireyin hayata bakışını şekillendiren önemli kurumların başında gelmektedir. Yapılan çalışmada üniversite öğrencilerinin toplumsal cinsiyet rollerine ilişkin tutumları üzerinde ailenin etkisi incelenmek istenmiştir. Araştırma, Bursa Teknik Üniversitesinde gerçekleştirilmiştir. Çalışmada ilk olarak öğrencilerin ve ailelerinin sosyo-demografik özellikleri analiz edilmiştir. Daha sonra öğrencilere, ailelerinde var olan ilişkiler sistemini analiz etmek için çeşitli yargılar yöneltilmiş ve bu yargılara verilen cevaplar ile öğrencilerin kendi görüşleri karşılaştırılmıştır. Araştırmaya katılan öğrencilerin %94’ü ev işlerinden hem kadının hem de erkeğin sorumlu olması gerektiğini, %99,3’ü ise evlendikten sonra kadının çalışmasının uygun olduğunu düşünmektedir. Öğrencilerin aile yapılarında, ailelerin eğitim düzeyi de göz önünde bulundurularak genel anlamda eşitlikçi bir yaklaşımın olduğu görülmektedir.
Methodological Issues in the Use and Application of International Tax Treaties (Part 1)
Authors:   Nextons Moscow Law Office, Bruk Boris Ya.
Published: December 2023

In this article the author intends to develop and justify the uniform approach to utilisation and application of the provisions of the conventions on avoidance of double taxation which specify the regime of taxation of particular types of income and capital (property). Stemming from the factors giving rise to double (multiple) taxation, the author examines the mechanisms of elimination of double taxation contained therein and the legal technicalities employed to lay down such mechanisms in the tax treaties. Furthermore, the author elaborates on his vision regarding the possible commonly shared algorithm that could eliminate or minimise the errors in utilisation and application of the distributive rules of the double taxation treaties taking into account peculiarities of terminology and wording of the treaties as well as the systematic approach of treaty drafters to the formulation of distributive rules (rules establishing the specifics of the tax treatment of certain types of income and capital) contained therein.
Judicial Independence: Ethics and the Media
Authors:   Journal “Russian Justice”, Povorova Elena A.
Published: December 2023

The image of the judiciary has an independent value characteristic. In the case of the formation of social representations by the judiciary, we are talking about legal meanings, the legal form of perception of reality through the implementation of judicial information policy, the presentation of the judicial community in the public space, the actions of judges and their public assessment by the judicial community itself and the society as a whole. Mediatisation of social space and the judiciary emphasises issues that seem to be related to the private sphere of a judge’s life – that is, his participation in social networks. The society is interested in the ethics of a judge from the point of view of the possibility of making higher demands to the bearer of power. But to what extent it is justified and whether ethics in general changes in the postmodern society are questions, the answers to which may affect the further development of the judiciary as an institution and its legitimisation in society.
Reflecting the Concept of Sustainable Development in the Regulations of the Russian Federation
Authors:   St. Petersburg State University, Eremin Viktor V.
Published: December 2023

The article is devoted to the way the domestic legislator at the federal and regional level approaches the issues of sustainable development. The article provides a brief analysis of the concept of sustainable development, its isolation and transformation into specific goals – Sustainable Development Goals (SDGs) proposed by the UN. The article analyses federal normative legal acts affecting sustainable development. Based on the results of the analysis of federal regulatory legal acts, it is concluded that despite the correct basic premise in Article 75.1 of the Constitution, which may well become the basis for the implementation of sustainable development in other regulatory legal acts, the regulation remains abstract and archaic. In addition, the legal acts regulating sustainable development are of a methodological nature rather than prescriptive. The basic hypothesis that sustainable development regulation can be characterised as chaotic and unsystematic was confirmed. As a possible solution to this situation, the author proposes the development of a roadmap for the introduction of the concept of sustainable development in regulatory and legal acts.

Honorary teachers refer to educators who have not received official appointments as civil servants (PNS) inside formal educational institutions, spanning from primary to secondary education levels. The objective of addressing the issues in this study pertains to the notion of justice and human rights in relation to the pay entitlements of honorary professors. In accordance with the Law on human rights and legal justice, any violation of the law and established human rights standards would be deemed unacceptable. The research methodology employed in this study adopts a normative juridical approach, which entails conducting a comprehensive literature review and analyzing theories, concepts, and legislation relevant to the research problems under investigation. The findings of the study indicate To address this issue, it is imperative to ensure diligent oversight in assessing the responsibilities and performance of educators, so enabling them to get a pay commensurate with their exertions, while maintaining fundamental human rights. The government through the ministry of education culture research technology must be a facilitator and directly involved in handling, limiting, and minimizing social inequality between a teacher with civil servant status and an ordinary honorary teacher. Because in essence the teacher is a noble profession that must be heeded and placed in a high degree.

Authors: Akande J.A , Adeogun A.I. , Uzosike A.S.
Published: December 2023

The released of dyes into hydrological systems in textile manufacturing, printing and other dyeing processes are hazardous and toxic to human and aquatic lives. Activated carbons have been remarkably used to treat dye contaminated waste water due to their large surface area and porosity, however regeneration and high cost have limited their applications. This study investigated the use of activated corn cobs (ACC) on the adsorption of methyl green dye from aqueous solution. The raw cobs were collected, crushed into particle size of about 600 μm and modified in-situ with KOH to prepare ACC which was characterized using some analytical techniques; Energy Dispersive X-ray (EDX) spectroscopy and Scanning Electron Microscopy (SEM). The absorbance of the dye solution was monitored at 500 nm with UV-Visible spectrophotometer. SEM results revealed the ACC has a porous surface with heterogeneous pores which became compact after dye adsorption. EDX confirmed the presence of C, O, H and K in the adsorbent. The suitability of the pseudo-first, pseudo second, Elovich and Intra-particle kinetic models for the removal of congo red dye onto ACC was examined. The equilibrium data were subjected to Langmuir, Freundlich, Tempkin and Dubinin-Radushkevich, Sips and Relich-Peterson isotherm models. The pseudo-second order kinetic model provided the best correlation and was found to be more statistically significant. Langmuir model was found to fit well based on the high values of the coefficient of regression R2 and low % standard error values. The monolayer adsorption capacity Qmax was found to be 37.81 mgg-1. Thermodynamic adsorption processes showed the spontaneous, exothermic and randomness of the systems with free energy change less than zero, enthalpy change (∆H) of -62.47 kJmol-1and entropy change (∆S) of 145.27Jmol-1K-1.

Published: December 2023

In this paper, a self-tuning hierarchical controller in which a Fuzzy logic controller supervises the control actions of a conventional PID has been proposed, implemented and presented. The controller has been applied to a control study of Fluid Catalytic Cracking (FCC) unit riser temperature, and regenerator temperature respectively. Performance comparison of the proposed Fuzzy-PID controller and the conventional PID was made in simulation studies of regulatory and servo performances of the two controller types. Six performance measures: Percent overshoot (OS), settling time (ST), integral absolute error (IAE), integral square error (ISE), integral time absolute error (ITAE) and integral time square error (ITSE) were employed as the tools for performance comparison between the conventional PID and the Fuzzy-PID controller. For the tracking of riser temperature with a set point at 524oC, the performance indicators under PID control gave the following results overshoot (14.5%); settling time (40 seconds) Integral absolute error (8.246), integral square error (3.3); integral time absolute error(1762);integral time square error (43.77) while for the same indicators under Fuzzy-PID control the following values: overshoot (3.3%); settling time (40 seconds) ;Integral absolute error (8.811); integral square error (14.5); integral time absolute error(280),;integral time square error (31.11) .The results allude to the superiority of the fuzzy-PID scheme over the PID scheme in tracking the optimal set point of riser temperature. More so, for tracking the regenerator set point temperature of 746oC, comparative study of step response under the two schemes gave the following results in six performance indicators: overshoot (PID(12.6%)/Fuzzy-PID(6%)); settling time (PID(80 seconds)/Fuzzy-PID(20seconds));Integral absolute error(PID(14.29)/Fuzzy-PID(8.63)); integral square error(PID(6.713).Fuzzy-PID(4.506)); integral time absolute error(PID(2858)/Fuzzy-PID(305.9)), integral time square error (PID(77.55)/Fuzzy-PID(33.05)).Moreover, the fuzzy-PID controller also showed superior performance over the conventional PID controller in terms disturbance rejection (regulatory response) of both riser and regenerator temperature. The results from this study suggest that the application of fuzzy-PID scheme to temperature control offers good promise of improved fluid catalytic cracking unit (FCCU) operations.

Impact of Water Absorption on Tensile Strength: A Comparative Study of Jute Fiber Composites with Various Fiber Content
Authors: Mohammad Salman Haque  , Istiak Ahmed Ovi  , Farah Samsi Prome  , Anika Hossain
Published: December 2023

The study focuses on replacing environmentally harmful synthetic materials with natural, renewable, and biodegradable jute fibers in Bangladesh. The hand-layup method incorporates Long jute fibres unidirectionally in an epoxy resin matrix. The primary goal of this research is to examine the effects of different fiber volume fractions on the tensile strength of the composite and how that strength is affected by the composite’s water absorption behavior following two months of weathering in water. The reduction in the tensile strength of weathered samples is attributed to the loss of fibres' structural integrity upon water absorption compared to raw samples. After being exposed to the water, the tensile strength of a 5% fiber composite sample drops by around 16.43%, whereas an epoxy sample with 15% fiber reinforcement drops by about 28.93%. The interactions between the fibers and the epoxy matrix, as well as the morphology of the fibers following fracture, were analyzed by SEM for both raw and weathered samples. Fiber-matrix debonding and fiber swelling due to water absorption and voids are observed in weathered specimens, whereas perfect fiber-matrix bonding is evident in raw composites.
INTERNATIONAL LATIN LANGUAGE PROFICIENCY TESTING SYSTEMS (NATIONAL LATIN EXAM, EUROPEAN LATIN EXAM AND EUROPEAN LATIN LINGUISTIC ASSESSMENT)
Authors: Голикова М.С.
Published: December 2023

Цель статьи – исследование существующих моделей сертификации по латинскому языку. Для этого были выбраны три наиболее известные системы тестирования: американская National Latin Exam (NLE), европейская European Latin Exam (ELEX), проводимая ассоциацией Euroclassica, и European Latin Linguistic Assessment (EULALIA), организатором которой является Университет Болоньи в рамках программы Европейского союза Erasmus+. Актуальность исследования связана c отсутствием в настоящие время общей системы сертификации по латинскому языку для русскоязычных обучающихся и с вопросом о целесообразности и эффективности языковой сертификации применительно к классическим мертвым языкам. В статье проанализированы и сопоставлены история создания экзаменов, их философия, формат проведения, цели, задачи и содержание. Новизна работы заключается в системном сравнительном исследовании международных экзаменов как нового этапа в истории классического образования. В результате исследования была выстроена история возникновения и развития тестирования по латинскому языку. Выяснилось, что существующие экзамены имеют общую тенденцию – заимствование моделей оценки владения живыми языками для классического языка. Такой подход может быть реализован лишь отчасти, так как латинский язык имеет свой уникальный набор ключевых компетенций, необходимых для освоения. Международная сертификация по латинскому языку – это движение, которое всесторонне влияет на подходы к преподаванию латинского языка.

The purpose of this paper is to investigate the existing models of Latin certification. For this purpose, three currently known testing systems were chosen: the American National Latin Exam (NLE), the European Latin Exam (ELEX) conducted by the European Association Euroclassica and the European Latin Linguistic Assessment (EULALIA), which was organized by the University of Bologna within the framework of the European Union Erasmus+ programme. The relevance of the research is due to the lack of a common certification system in Latin for Russian-speaking learners and due to the question of the expediency and effectiveness of language certification in relation to classical dead languages. The article analyses and compares the history of the creation of the examinations, their philosophy, format, goals, objectives and content. The novelty lies in the systematic comparative study of international examinations as a stage in the history of classical education. As a result of the study, the history of the emergence and development of Latin language testing has been constructed. It turned out that the existing examinations have a common tendency: borrowing models of assessment of proficiency in living languages for the classical language. This approach can only be partially realized as Latin has its own unique set of core competencies to master. International Latin language certification is a movement that is comprehensively influencing approaches to Latin language teaching.
Reviews on Indirect Compulsory Performance at the Time of the Judgment on the Merits: focusing on appeal process, pronouncement of provisional execution, and addition of claims at appellate trial
Authors:   Legal Research Institute of Chonnam National University, Lee Hyo-In
Published: December 2023

Indirect compulsory performance is a method used by a court to enforce irreplaceable acts or omissions. The Supreme Court has allowed indirect compulsory performance at the time of the judgment on the merits (referred to as “Indirect Compulsory Per- formance” herein) since 1996. This paper focuses on some legal issues that may arise in trials involving Indirect Compulsory Performance. First, the appeal process for Indirect Compulsory Performance should follow the same procedures as those for judgments on the merits. This ensures that Indirect Compulsory Performance can be executed either concurrently with or subsequent to the judgment on the merits, while adhering to the trial procedure and mandate form. Second, a court should declare provisional execution for Indirect Compulsory Performance if such execution is pronounced with the judgment on the merits. Conversely, this declaration should be avoided when no provisional execution accompanies the judgment on the merits. This ensures concurrent execution with the judgment on the merits, thereby enhancing the overall effectiveness of the judicial decision. Lastly, the addition of Indirect Compulsory Performance during the appellate trial should not be allowed, as it could breach the court’s jurisdiction and potentially disrupt the balance between creditors and debtors.
JWST Reveals Widespread CO Ice and Gas Absorption in the Galactic Center Cloud G0.253+0.016

We report JWST NIRCam observations of G0.253+0.016, the molecular cloud in the Central Molecular Zone known as “The Brick,” with the F182M, F187N, F212N, F410M, F405N, and F466N filters. We catalog 56,146 stars detected in all six filters using the crowdsource package. Stars within and behind The Brick exhibit prodigious absorption in the F466N filter that is produced by a combination of CO ice and gas. In support of this conclusion, and as a general resource, we present models of CO gas and ice and CO2 ice in the F466N, F470N, and F410M filters. Both CO gas and ice contribute to the observed stellar colors. We show, however, that CO gas does not absorb the Pfβ and Huϵ lines in F466N, but that these lines show excess absorption, indicating that CO ice is present and contributes to observed F466N absorption. The most strongly absorbed stars in F466N are extincted by ∼2 mag, corresponding to >80% flux loss. This high observed absorption requires very high column densities of CO, and thus a total CO column that is in tension with standard CO abundance and/or gas-to-dust ratios. This result suggests the CO/H2 ratio and dust-to-gas ratio are greater in the Galactic Center than in the Galactic disk. Ice and/or gas absorption is observed even in the cloud outskirts, implying that additional caution is needed when interpreting stellar photometry in filters that overlap with ice bands throughout galactic centers.

We report on a comprehensive multiwavelength study of the pulsars in the globular cluster (GC) M5, including the discovery of M5G, a new compact noneclipsing “black widow” pulsar. Thanks to the analysis of 34 yr of radio data taken with the Five-hundred-meter Aperture Spherical radio Telescope and Arecibo telescopes, we obtained new phase-connected timing solutions for four pulsars and improved those of the other three. These have resulted in, among other things, (a) much improved proper motions for five pulsars, with transverse velocities (relative to the cluster) that are smaller than their respective escape velocities; (b) 3σ and 1.5σ detections of Shapiro delays in M5F and M5D, respectively; and (c) greatly improved measurement of the periastron advance in M5B, whose value of

) neutron star. The binary pulsars M5D, M5E, and M5F are confirmed to be in low-eccentricity binary systems, the low-mass companions of which are newly identified to be He white dwarfs using Hubble Space Telescope data. Four pulsars are also found to be associated with X-ray sources. Similarly to the eclipsing pulsar M5C, M5G shows little or no nonthermal X-ray emission, indicative of weak synchrotron radiation produced by intrabinary shocks. All seven pulsars known in M5 have short spin periods (<8 ms), and five are in binary systems with low orbital eccentricities. These characteristics differ from the overall GC pulsar population but confirm the expectations for the pulsar population in a cluster with a small rate of stellar encounters per binary system.

It is well accepted that the physical properties obtained from the solar magnetic field observations of active regions (ARs) are related to solar eruptions. These properties consist of temporal features that might reflect the evolution process of ARs, and spatial features that might reflect the graphic properties of ARs. In this study, we generated video data sets with timescales of 1 day and image data sets of the SHARP radial magnetic field of the ARs from 2010 May to 2020 December. For the ARs that evolved from “quiet” to “active” and erupted the first strong flares in 4 days, we extract and investigate both the temporal and spatial features of ARs from videos, aiming to capture the evolution properties of their magnetic field structures during their transition process from “quiet” (non–strong flaring) to “active” (strong flaring). We then conduct a comparative analysis of the model performance by video input and single-image input, as well as of the effect of the model performance variation with the prediction window up to 3 days. We find that for those ARs that erupted the first strong flares in 4 days, the temporal features that reflect their evolution from “quiet” to “active” before the first strong flares can be recognized and extracted from the video data sets by our network. These features turn out to be important predictors that can effectively improve strong-flare prediction, especially by reducing the false alarms in a nearly 2 day prediction window.

We present imaging and spectroscopic diagnostics of a long filament during its formation with the observations from the Chinese Hα Solar Explorer and Solar Dynamics Observatory. The seed filament first appeared at about 05:00 UT on 2022 September 13. Afterward, it grew gradually and connected to another filament segment nearby, building up a long filament at about 20:00 UT on the same day. The CHASE Hα spectra show an obvious centroid absorption with mild broadening at the main spine of the long filament, which is interpreted as evidence of filament material accumulation. More interestingly, near the footpoints of the filament, persistent redshifts have been detected in the Hα spectra during the filament formation, indicating continuous drainage of filament materials. Furthermore, through inspecting the extreme-ultraviolet (EUV) images and magnetograms, it was found that EUV jets and brightenings appeared repeatedly at the junction of the two filament segments, where opposite magnetic polarities converged and canceled each other continuously. These results suggest the occurrence of intermittent magnetic reconnection that not only connects magnetic structures of the two filament segments but also supplies cold materials for the filament channel likely by the condensation of injected hot plasma, even though a part of the cold materials falls down to the filament footpoints at the same time.
Rapid Premerger Localization of Binary Neutron Stars in Third-generation Gravitational-wave Detectors

Premerger localization of binary neutron stars (BNSs) is one of the most important scientific goals for the third-generation (3G) gravitational-wave detectors. It will enable the electromagnetic observation of the whole process of BNS coalescence, especially for the premerger and merger phases, which have not been observed yet, opening a window for deeper understandings of compact objects. To reach this goal, we describe a novel combination of multiband matched filtering and semianalytical localization algorithms to achieve early-warning localization of long BNS signals in 3G detectors. Using our method we are able to efficiently simulate one month of observations with a three-detector 3G network, and show that it is possible to provide accurate sky localizations more than 30 minutes before the merger. Our simulation shows that there could be ∼10 (∼100) BNS events localized within 100 deg2, 20 (6) minutes before merger, per month of observation.

The fate of Mercury’s exospheric volatiles and, in a lesser way, of the refractory particles absorbed in the first few centimeters of the surface both depend highly on the temperature profile with depth and its diurnal variation. In this paper, we review several mechanisms by which the surface temperature might control the surface/exosphere interface. The day/night cycle of the surface temperature and its orbital variation, the temperature in the permanent shadow regions, and the subsurface temperature profiles are key thermal properties that control the fate of the exospheric volatiles through the volatile ejection mechanisms, the thermal accommodation, and the subsurface diffusion. Such properties depend on the solar illumination from large to small scales but also on the regolith structure. The regolith is also space-weathered by the thermal forcing and by the thermal-mechanical processing. Its composition is changed by the thermal conditions. We conclude by discussing key characteristics that need to be investigated theoretically and/or in the laboratory: the dependency of the surface spectra with respect to temperature, the typical diffusion timescale of the volatile species, and the thermal dependency of their ejection mechanisms.
An Ultra-Refined Grammar for Interactions: Thoughts on Robert Aumann’s Philosophy of Game Theory
Authors: Linsbichler Alexander
Published: December 2023

Cette note identifie et commente certains traits cruciaux de la philosophie de la théorie des jeux de Robert Aumann. Ce faisant, il vise à dégager et à exprimer certaines notions tacitement détenues par de nombreux théoriciens des jeux et, idéalement, à déclencher une réflexion ultérieure sur la philosophie de la théorie des jeux en général. Selon ma reconstruction de la position d’Aumann, des règles de langage sophistiquées et relativement précises – une grammaire ultra-raffinée des interactions – constituent le cœur de la théorie des jeux. Par conséquent, le cœur de la théorie des jeux est dépourvu, ou presque dépourvu, de contenu empirique. La dernière section propose une nomenclature pour discuter lucidement des relations entre les théories, les différents types de modèles et « le monde réel » et s’en sert ensuite pour expliquer et modifier légèrement les remarques de Robert Aumann sur le rôle de la vérité et de la fécondité dans la théorie des jeux.

This research paper investigated fixed point results for almost ($ \zeta-\theta _{\rho } $)-contractions in the context of quasi-metric spaces. The study focused on a specific class of ($ \zeta -\theta _{\rho } $)-contractions, which exhibit a more relaxed form of contractive property than classical contractions. The research not only established the existence of fixed points under the almost ($ \zeta -\theta _{\rho } $)-contraction framework but also provided sufficient conditions for the convergence of fixed point sequences. The proposed theorems and proofs contributed to the advancement of the theory of fixed points in quasi-metric spaces, shedding light on the intricate interplay between contraction-type mappings and the underlying space's quasi-metric structure. Furthermore, an application of these results was presented, highlighting the practical significance of the established theory. The application demonstrated how the theory of almost ($ \zeta -\theta _{\rho } $)-contractions in quasi-metric spaces can be utilized to solve real-world problems.

Recently, convolutional neural networks (CNNs) for classification by time domain data of multi-signals have been developed. Although some signals are important for correct classification, others are not. The calculation, memory, and data collection costs increase when data that include unimportant signals for classification are taken as the CNN input layer. Therefore, identifying and eliminating non-important signals from the input layer are important. In this study, we proposed a features gradient-based signals selection algorithm (FG-SSA), which can be used for finding and removing non-important signals for classification by utilizing features gradient obtained by the process of gradient-weighted class activation mapping (grad-CAM). When we defined $ n_ \mathrm{s} $ as the number of signals, the computational complexity of FG-SSA is the linear time $ \mathcal{O}(n_ \mathrm{s}) $ (i.e., it has a low calculation cost). We verified the effectiveness of the algorithm using the OPPORTUNITY dataset, which is an open dataset comprising of acceleration signals of human activities. In addition, we checked the average of 6.55 signals from a total of 15 signals (five triaxial sensors) that were removed by FG-SSA while maintaining high generalization scores of classification. Therefore, FG-SSA can find and remove signals that are not important for CNN-based classification. In the process of FG-SSA, the degree of influence of each signal on each class estimation is quantified. Therefore, it is possible to visually determine which signal is effective and which is not for class estimation. FG-SSA is a white-box signal selection algorithm because it can understand why the signal was selected. The existing method, Bayesian optimization, was also able to find superior signal sets, but the computational cost was approximately three times greater than that of FG-SSA. We consider FG-SSA to be a low-computational-cost algorithm.
