Magnetization properties, super-stable points, and cycles of antiferromagnetic spin-1 diamond chains with nodal-nodal interactions
Authors: Amatuni G. , Burdik Č. , Poghosyan H. , Ananikyan L. , Ananikian N. 
Published: December 2023

Abstract
This study is devoted to the discovery of super-stable points and cycles in antiferromagnetic Ising and Ising-Heisenberg models with spin 1 on diamond chains with nodal-nodal interactions. These phenomena are important for understanding the complex behavior of magnetic systems. We specifically investigate their connection with magnetization plateaus, which serve as critical indicators of the model’s characteristics. Employing the recurrence relations technique, we derive multidimensional rational mappings that give insights about the statistical properties of the models. Carefully examining the stability properties of these mappings, in particular, by analyzing the maximum Lyapunov exponent, we have revealed the complex relationship between the magnetization plateau and dynamic properties. Throughout our extensive research, we have comprehensively studied the existence and behavior of super-stable points and cycles for various parameter configurations in spin-1 models on the diamond chains. By highlighting the basic properties of dynamics and stability, our research advances a fundamental understanding of complex magnetic systems and their fascinating properties.
Phase space analysis of the 3-level Lipkin-Meshkov-Glick model using parity adapted U(D)-spin coherent states
Authors: Mayorgas A , Guerrero J , Calixto M 
Published: December 2023

Abstract
We study the phase-space properties of the 3-level Lipkin-Meshkov-Glick as paradigmatic case of critical, parity symmetric, N-quDit systems undergoing a quantum phase transition in the thermodynamic limit N
→ ∞. We generalize U(2) spin coherent states to U(D) (quDits), and define the coherent state representation Qψ
(Husimi function) of a symmetric N- quDit state |ψ〉 in the phase space ℂP

D −1 = U(D)/[U(1) × U(D − 1)]. This allows us to define parity adapted U(D) coherent states (𝕔-DCATs), which reproduce accurately the lowest energy Hamiltonian eigenstates obtained by numerical diagonalization. We visualize precursors of the QPTs by plotting localization measures (Husimi function and its moments) of the parity adapted U(D) coherent states and the numerical Hamiltonian eigenstates for a finite number of particles.

Authors: Kuwata Seiichi 
Published: December 2023

Abstract
The first-order formalism of relativistic wave equations, such as the Dirac (spin s = 1=2) and the Kemmer (s = 1) equations, are generalized to the Bhabha (one s) equation, where the generalized gamma matrices for space-time dimension (3+1) are labeled with not only s but also s′ ∈ {s, s − 1,… s − ⎣s⎦}. We show that for s′ = s, the generators (D, Pμ
, Kμ
, Sμν
) constructed from the generalized gamma matrices satisfy the conformal algebra, in which we find that the null-eigenstates |s

Towards gravitational QNM spectrum from quantum spacetime
Authors: Herceg Nikola , Jurić Tajron , Samsarov Andjelo , Smolić Ivica 
Published: December 2023

AbstractThe effective potential for the axial mode of gravitational wave on noncommutative Schwarzschild background is presented. Noncommutativity is introduced via deformed Hopf algebra of diffeomorphisms by means of a semi-Killing Drinfeld twist. The analysis is performed up to the first order in perturbation of the metric and noncommutativity parameter. This results in a modified Regge-Wheeler potential with the strongest differences in comparison to the classical Regge-Wheeler potential being near the horizon.

Abstract
The formula ⋆ mod ō(ħ

k
) of Kontsevich’s star-product with harmonic propagators was known in full at ħ

k⩾6 since 2018 for generic Poisson brackets, and since 2022 also at k = 7 for affine brackets. We discover that the mechanism of associativity for the star-product up to ō(ħ
6) is different from the mechanism at order 7 for both the full star-product and the affine star-product. Namely, at lower orders the needed consequences of the Jacobi identity are immediately obtained from the associator mod ō(ħ
6), whereas at order ħ
7 and higher, some of the necessary differential consequences are reached from the Kontsevich graphs in the associator in strictly more than one step.

Published: December 2023

Abstract
This paper presents a comparative method for accurately measuring dimension over two pins of flexspline of harmonic reducer. Firstly, we design a measuring system and introduce its composition and measuring principle. Secondly, we propose an alignment method to reduce measurement error caused by eccentric installation. Finally, the alignment method proposed was experimentally verified, and the dimension over two pins of flexspline was measured. The verification results showed that the proposed alignment method had a positive effect, and its feasibility was confirmed. Dimension over two pins of standard flexspline was found to be 64.855 mm. By employing the proposed comparison method, the dimension over two pins of the three measured flexsplines was 64.848 mm, 64.862 mm, and 64.857 mm, respectively. The measurement accuracy achieved was less than 10 μm, meeting the required measurement accuracy standards and significantly improving upon traditional measurement methods.

Published: December 2023

Abstract
For unmanned aerial vehicles (UAVs) slung-load systems, the payload of UAVs may suffer swing caused by inertia and external disturbances during the delivery process, posing a threat to system safety. Simultaneously tracking the trajectory and suppressing the payload swing is a challenging task. In this paper, a control design method is presented for trajectory tracking and swing suppression for a UAV delivery system. A feedforward design with the S-shaped trajectory is employed to suppress the payload swing, and a feedback hierarchical sliding mode control is utilized for trajectory tracking. Furthermore, stability analysis of the control system is conducted using the Lyapunov function, and simulation experiments are performed in MATLAB to validate the performance of the controller.

Published: December 2023

Abstract
For the temperature drift problem of a shunt-type current sensor, this paper adopts a temperature compensation model based on the fusion of temperature segmentation linear and clustering division, which focuses on the consideration of the current sensor system as a whole, as well as versatility and complexity, etc., to ensure the measurement accuracy of a single sensor, while improving the speed of multi-sensor temperature compensation. Experimental results show that the current sensor after the model compensation, in the 15 A or more experiments measured in the current range of the accuracy is maintained within ±0.5%, compared with the sensor before the compensation of the measurement accuracy increased by 3%, but also reached the domestic and foreign current sensor products in the corresponding range of the compensation of the accuracy. The model effectively improves the temperature stability of the sensor and the system detection accuracy and provides practical application value for the temperature compensation of shunt-type current sensors in mass production.

Omnibus Law on Job Creation: Tug of War over Environmental Protection Authority Amid the Climate Crisis
Authors: Najib Ahmad Ainun , Saraswati Retno 
Published: December 2023

Abstract
This article analyses the relationship between national and local governments regarding environmental protection amid the climate crisis after the Omnibus Law on Job Creation issuance. It is a normative study of legal concepts in the statutory system. The results point out that Omnibus Law on Job Creation has changed the paradigm of environmental protection from “permission” to “consent” or “agreement.” The policy weakened the local government’s role in protecting the environment amidst the climate crisis. Apart from that, the Omnibus Law has also created a pattern of centralization by reducing the authority of local governments—which is only interpreted as a deconcentrated primate in implementing the law provisions.

Abstract
Allocating participating interest (“PI”) is crucial for managing upstream oil and gas operations as it determines the rights and obligations of contractors, including their responsibility to ensure health, safety, and environmental awareness under the regulatory framework, production sharing contract (“PSC”) or operations agreement (“OA”). This paper examines the role of local governments as 10% PI holders towards promoting environmental compliance and ensuring sustainable oil and gas development. The research adopts a juridical-normative approach by reviewing secondary data sources and academic literatures in order to identify specific forms of environmental responsibility available to local governments as 10% PI holders under the progressive law doctrine, relevant regulations within the context of upstream operations and provide recommendations to improve their effectiveness in fulfilling their environmental obligations. The findings contribute to the sustainable management of the sector by providing valuable regulatory insights into the environmental responsibility of local governments as 10% PI holders.
Regulation Urgency of the Misleading “Greenwashing” Marketing Concept in Indonesia
Authors: Irawati  , Prananingtyas Paramita , Wulan Retno Catur 
Published: December 2023

Abstract
Greenwashing is a term that refers to a company’s marketing strategy or activities in providing an environmentally friendly image, both in terms of products produced, objectives, or corporate values, without actually carrying out activities that have a good impact on the environment. Greenwashing activities are inseparable from green marketing, a product marketing activity that focuses on the environmental awareness of potential consumers. Consumer protection for greenwashing products in Indonesia has not been specifically regulated. Indonesia has several legal instruments that can be linked to greenwashing activities. Among them are consumer protection law, broadcasting law, and environmental law. As a developed country, America has greater environmental awareness in terms of regulation and law enforcement authority on greenwashing activities. The United States has published an FTC Green Guides (Green Guides) guideline. However, through environmental regulations, Indonesia continues to develop environmental and economic instruments through the eco-label system.

Authors: Purwanti Ani , Setiawan Fajar Ahmad , Natalis Aga 
Published: December 2023

Abstract
People’s mining contributes to conflict and environmental degradation, particularly in developing nations. This is a socio-legal study. The study’s findings indicate that mediation is viable, cost-effective, and respectful for resolving smallholder mining disputes. Mediation is a voluntary procedure involving a neutral third party to reach an acceptable solution for both parties. The advantages of mediation include time and cost savings, the maintenance of relationships between parties, the incorporation of local knowledge and cultural practices, the promotion of environmental sustainability, and the facilitation of the development of legal and regulatory frameworks that support the sustainable development of smallholder mining communities. Although mediation faces obstacles such as a lack of trained mediators, potential power imbalances between parties, and the need for trust and cooperation, its usefulness in resolving conflicts and preserving the environment makes it essential for promoting sustainable development.

Authors: Soelistyo Henry 
Published: December 2023

Abstract
In the last few decades, climate change has created a number of weather anomalies along with their distortive impacts on the environment. Various forms of natural disasters such as floods, landslides, droughts and forest fires disrupt the cultivation of the agricultural sector and strengthen food security. The problem is, the impact of climate change like that has caused crop failures, food crises and even social crises. In fact, climate change is a major risk to good development outcomes. Consequently, there is a need to integrate climate action into the core of development agenda. This sociological juridical research aims to examine what policies and steps the government must prepare to save the agricultural sector, food availability, and the environment. For Indonesia, empowering Intellectual Property Rights (IPR) is a strategy that needs to be used as a guide and direction. The legal system for patents, new plant varieties and geographical indications needs to be used as an instrument as well as a driving force to support agricultural development, food security and distribution of commodities for the people of Indonesia whose population continues to grow.
