Mittag-Leffler function based security control for fractional-order complex network system subject to deception attacks via Observer-based AETS and its applications
Authors: Mubeen Tajudeen M , Perumal R , Kumar Thakur Ganesh , Priya Bandana 
Published: July 2024

Abstract
The goal of this paper is to investigate the security control for uncertain fractional-order delayed complex network systems under deception attacks using the Mittag-Leffler function and observer-based adaptive event-triggered scheme (AETS) with the fractional commensurate order in q ∈ (0, 1). The adaptive event-triggering scheme is used during the data transmission process from the sensors to the observer, where the triggering threshold can be dynamically modified to reduce resource waste. We make a novel model for the estimation error system that takes into account both the effects of the adaptive event-triggered scheme and the effects of deception attacks. A sufficient condition is obtained to guarantee the stochastic mean-square stability of the augmented error system using the Mittag-Leffler (M-L) functions and the Lyapunov functional method and by using the singular value decomposition (SVD) and linear matrix inequality (LMI) techniques, the co-design problem of desired observer and controller gains is found, and it is shown that the solution ensures the stability of a closed-loop uncertain fractional-order complex networked system. At the end of this study, two numerical examples and diesel engine system model are given to show that the above findings are correct.
The novel WASPAS method for roughness of bipolar fuzzy sets based bipolar fuzzy covering
Authors: Tufail Faiza , Shabir Muhammad 
Published: July 2024

Abstract
The research employs Covering-based Rough Set and Fuzzy Set theories to handle uncertainty in data analysis. However, when dealing with data uncertainty and bipolarity in various scenarios, the Bipolar Fuzzy Set (BFS) theory proves advantageous by simultaneously managing positive and negative information. Other sets, such as traditional fuzzy sets, often fail to capture this duality, leading to less comprehensive data analysis. This study pioneers a new methodology called the Theory of Roughness of Bipolar Fuzzy Sets, integrating Fuzzy Covering, Monotone Fuzzy Covering, and Bipolar Fuzzy Covering to propose an innovative decision-making approach. This novel concept undergoes comprehensive structural analysis. By incorporating the bipolar fuzzy covering based bipolar fuzzy rough set (

BFCBFRS

) model into conventional decision-making methods like the

WASPAS

technique, the research introduces a fresh perspective to address Multi-Criteria Decision-Making (

MCDM

) challenges. The efficacy of this extended method is evaluated by applying it to agricultural diagnosis, demonstrating its superiority over existing approaches through comparative analysis.
Transmission-type frequency selective surface with polarization modulation
Authors: Xu Honghui , Zhou Dongfang , Liu Qikun , Tang Min , Qian Hang 
Published: July 2024

Abstract
In this work, a transmission-type frequency selective surface (FSS) with polarization modulation is proposed. This design achieves cross-polarized transmission under both x- and y-polarized normal incidences, while supporting co-polarized transmission at a 45° incidence polarization angle. Consequently, the structure can serve as a polarization rotating FSS (PR-FSS) or a conventional bandpass FSS. The design consists of two fundamental units, corresponding to x- and y-polarized PR-FSS, arranged according to a specific group array paradigm. This arrangement preserves the cross-polarization transmission functionality of each unit. In addition, at a 45° polarization angle, the symmetry of the paradigm with respect to the electric field enables it to support co-polarized transmission. A prototype containing a 12 × 12 element array is constructed and tested. The measured results demonstrate good agreement with the simulation results.
The diffusion behaviour of coupled particle rings driven by self-propelled particles in a two-dimensional reflection channel
Authors: Cheng Zhiguo , Wang Bing 
Published: July 2024

Abstract
Investigated the diffusion behavior of self-propelled coupled particle rings in a two-dimensional channel considering particle collisions. The channel geometry and noise regulation play crucial roles in directing transport within the system. Observed a significant alteration in the diffusion behavior of the particle rings at specific stages of the collision process, accompanied by corresponding changes in the diffusion coefficient. As the modulation phase shift increases, the mean square displacement (MSD) of the particle rings displays periodic fluctuations. The binding force between the particle rings partially restricts the growth of the MSD. An increase in white noise intensity enhances the diffusion behavior. The impact of self-propulsion speed is influenced by the modulation parameters. The sign of the modulation parameter dictates the correlation of the self-propulsion speed. Furthermore, the number of particle rings in the channel introduces a complex effect on the diffusion behavior.

Published: July 2024

Abstract
The application of UAV (Unmanned Aerial Vehicle) remote sensing and aerial photography technology is more and more widely. Aiming at the problem of object detection in remote sensing or aerial images, the paper proposes an object detection algorithm for UAV remote sensing images based on YOLOv5s, called URS-YOLOv5s (UAV Remote Sensing - YOLOv5s). Firstly, the paper designs Cross-Connected Dense Network (CCDNet), where each convolution layer is concatenated to the second convolution layer. Secondly, the paper designs Across-Path Fusion Network (APFNet), which the last feature fusion path is directly fused with the backbone network. It increases the location information and semantic information of deep features. Finally, the loss function of the original algorithm is replaced by EIoU (Focal and Efficient IoU), which makes the calculation method of the overall loss more appropriate. On AI-TOD and Visdrone2019 datasets, experiments show that the accuracy of URS-YOLOv5s on mAP@0.5 is 6.3% and 9% higher than YOLOv5s. In addition, compared with YOLOv3 and YOLOv5l which have good detection effect, URS-YOLOv5s has the characteristics of faster detection speed and lower computational cost. Meanwhile, URS-YOLOv5s is more suitable for deployment to mobile devices, such as drones with limited performance.
Healthy Horndeski cosmologies with torsion
Authors: Mironov S. , Valencia-Villegas M. 
Published: July 2024

Abstract
We show that the full Horndeski theory with both curvature and torsion can support nonsingular, stable and subluminal cosmological solutions at all times. Thus, with torsion, the usual No-Go theorem that holds in a curved spacetime is avoided. In particular, it is essential to include the nonminimal derivative couplings of the ℒ5 part of the Horndeski action (Gμν
∇
μ
∇
νϕ, and (∇2
ϕ)3). Without the latter a No-Go already impedes the eternal subluminality of nonsingular, stable cosmologies.
First constraints on non-minimally coupled Natural and Coleman-Weinberg inflation and massive neutrino self-interactions with Planck+BICEP/Keck
Authors: Bostan Nilay , Choudhury Shouvik Roy 
Published: July 2024

AbstractIn this work, for the first time in literature, we study the predictions of non-minimally coupled Natural and Coleman-Weinberg potentials in thens-rplane, and an extended ΛCDM model where we include non-standard self-interactions among massive neutrinos, mediated by a heavy scalar or vector boson. Constraints were derived using the Planck 2018 + BICEP/Keck 2018 datasets along with other data. For the inflationary potentials, we consider two different formulations in gravity that are non-minimally coupled to the scalar field of the inflaton:Metric and Palatini.We only consider the self-interaction to be present amongτ-neutrinos and only at moderate strengths. This is because strong interactions amongτ-neutrinos, or any strength self-interaction among electron- and muon-neutrinos, as well as any strength flavor-universal interactions, are strongly disfavoured from particle physics experiments. In terms of cosmological data, we use the latest public CMB datasets from Planck 2018 and BICEP/Keck 2018 collaborations, along with other data from CMB lensing, BAO, RSD, and SNe Ia luminosity distance measurements. We find that there are some situations where predictions from the inflationary models are ruled out at more than 2σby the minimal ΛCDM+rmodel, but they are allowed in the self-interacting neutrino scenario.
A gamma-ray study of galactic PeVatron candidates LHAASO J1825-1326 and LHAASO J1839-0545
Authors: Costa Rubens Jr. , Götz Debora B. , Anjos Rita C. , Stuani Pereira Luiz A. , Mello Alexandre J.T.S. 
Published: July 2024

Abstract
Recent studies by LHAASO have shown the presence of high-luminosity PeVatrons in our Galaxy. We examine two notable sources, each consisting of two pulsars, detected by LHAASO. We study gamma and
cosmic-ray emissions from the surroundings of these pulsars.
We used the Gammapy software to perform gamma-ray measurements from these sources in anticipation of future analyses to be carried out with the CTAO, which is now under development. Furthermore, the particle propagation throughout the Galaxy was simulated using the GALPROP software, accounting for emission from energy losses due to spin-down. As a result, we present the particle spectra generated during this propagation phase along with the corresponding gamma-ray emission.
The findings suggest that CTAO may have the capability to detect these sources and show that the data can be explained by gamma rays coming from a leptonic model.
Atomically self-healing of structural defects in monolayer WSe2

Published: July 2024

Abstract
Minimizing disorder and defects is crucial for realizing the full potential of two-dimensional transition metal dichalcogenides (TMDs) materials and improving device performance to desired properties. However, the methods in defect control currently face challenges with overly large operational areas and a lack of precision in targeting specific defects. Therefore, we propose a new method for the precise and universal defect healing of TMD materials, integrating real-time imaging with scanning transmission electron microscopy (STEM). This method employs electron beam irradiation to stimulate the diffusion migration of surface-adsorbed adatoms on TMD materials grown by low-temperature molecular beam epitaxy (MBE), and heal defects within the diffusion range. This approach covers defect repairs ranging from zero-dimensional vacancy defects to two-dimensional grain orientation alignment, demonstrating its universality in terms of the types of samples and defects. These findings offer insights into the use of atomic-level focused electron beams at appropriate voltages in STEM for defect healing, providing valuable experience for achieving atomic-level precise fabrication of TMD materials.
Magnetoresistance hysteresis in the superconducting state of kagome CsV3Sb5
Authors: Le 乐 Tian 天 , Liu 刘 Jinjin 锦锦 , Wang 王 Zhiwei 秩伟 , Lin 林 Xiao 效 
Published: July 2024

Abstract
The hysteresis of magnetoresistance observed in superconductors is of great interest due to its potential connection with unconventional superconductivity. In this study, we perform electrical transport measurements on kagome superconductor CsV3Sb5 nanoflakes and uncover unusual hysteretic behavior of magnetoresistance in the superconducting state. This hysteresis can be induced by applying either a large DC or AC current at temperatures (T) well below the superconducting transition temperature (T
c). As T approaches T
c, similar weak hysteresis is also detected by applying a small current. Various scenarios are discussed, with particular focus on the effects of vortex pinning and the presence of time-reversal-symmtery-breaking superconducting domains. Our findings support the latter, hinting at chiral superconductivity in kagome superconductors.

Abstract
In this work, considering the preformation factor of the emitted two protons in parent nucleus

and the effect of the parent nucleus deformation, based on the Wentzel-Kramers-Brillouin approximation and Bohr-Sommerfeld quantization condition, we improve a simple phenomenological model proposed by Bayrak [J. Phys. G: 47, 025102 (2020)] to systematically study

radioactivity half-lives. This model contains two adjustable parameters

and

, which are related to the depth of nuclear potential and effect of deformation. The calculated results show that this model can effectively reproduce the experimental data with a corresponding root-mean-square (RMS) standard deviation of σ = 0.683. For comparison, we include the Gamow-like model (GLM) proposed by Liu et al. [Chin. Phys. C 45, 044110 (2021)], generalized liquid drop model (GLDM) proposed by Cui et al. [Phys. Rev. C 101, 014301 (2020)], effective liquid drop model (ELDM) proposed by M. Gonalves et al. [Phys. Lett. B 774, 14 (2017)], two-potential approach with Skyrme-Hartree-Fock (TPASHF) proposed by Pan et al. [Chin. Phys. C 45, 124104 (2021)], phenomenological model with a screened electrostatic barrier (SEB) propoesed by Zou et al. [Chin. Phys. C 45, 104101 (2021)], unified fission model (UFM) proposed by Xing et al. [Chin. Phys. C 45, 124105 (2021)], Coulomb and proximity potential model for deformed nuclei (CPPMDN) proposed by Santhosh [Phys. Rev. C 104, 064613 (2021)], two-parameter empirical formula proposed by Liu et al. [Chin. Phys. C 45, 024108 (2021)], and four-parameter empirical formula proposed by Sreeja et al. [Eur. Phys. J.

radioactive half-lives of some possible potential nuclei whose

Abstract
Nonlinear modeling of mitigation of the edge localized mode (ELM) with resonant magnetic perturbation (RMP) is performed for the HL-2A tokamak, utilizing the three-dimensional (3D) magnetohydrodynamic code JOREK. Based on the 3D equilibrium established after application of the

coil current with odd parity, ELM mitigation is successfully simulated consistent with the experimental result. Nonlinear simulations show strong mode coupling among toroidal Fourier harmonics, allowing redistribution of the magnetic energy such that the most unstable toroidal mode saturates at a lower level. This magnetic energy cascade offers an explanation of the RMP-induced ELM mitigation achieved in HL-2A. Detailed examination of the simulation results shows persistent resonant field screening even during the ELM mitigation phase. Finite plasma resistivity however does enable partial penetration of the resonant field thus modifying the edge magnetic topology and characteristics of the edge transport. Plasma radial profiles undergo pronounced changes around the pedestal region, when the magnetic energy of the most unstable toroidal mode reaches the maximum value. Systematic scans of the applied RMP coil current with the JOREK simulations find a threshold value of around

Application of non-axisymmetric magnetic field for control of Alfvén eigenmodes in KSTAR
Authors: Kim Kimin , Kang Jisung , Rhee Tongnyeol , Kim Minho , Kim Junghee 
Published: July 2024

Abstract
We report an experimental examination of non-axisymmetric (3D) magnetic fields for the control of Alfvén eigenmodes (AEs) in KSTAR. Application of the phase-sweeping n = 1 3D magnetic field identifies the effective 3D field phase and threshold amplitude for suppression of toroidal AEs. Such observations indicate that at least two conditions on the 3D field phase and amplitude should be satisfied for the AE suppression. The phase window of AE suppression is largely resonant and thereby overlapped with that of mode locking, while the threshold of mode locking is slightly higher than that of AE suppression, which implies a narrow 3D configuration window for AE suppression. Numerical analyses on the AE stability and fast ion phase-space transport suggest that the key mechanism of the AE suppression is the reduction of the AE drive through redistribution of fast ion phase-space distribution by strong resonant interactions of the fast ions with the 3D magnetic field.

Published: July 2024

Abstract
The growth of transparent 5-chloro-2-nitroaniline (5C2NA) crystals was achieved using the slow evaporation solution technique in this paper. The X-ray diffraction and Fourier transform-infrared spectroscopy analysis confirmed the crystal structure and molecular fingerprints of 5C2NA, respectively. UV–Vis and photoluminescence (PL) spectroscopy were employed to investigate the material’s band gap and ground state absorption, respectively. The thermogravimetric analysis indicates that the stability of the grown crystals was achieved at up to 211 °C. Dielectric measurements and Urbach plots suggest the presence of fewer defects in 5C2NA crystals. Terahertz time-domain spectroscopy was utilized to observe the variation of absorption coefficient and refractive index in the terahertz frequency regime. Nonlinear optical effects, such as saturable absorption (SA) and reverse saturable absorption (RSA), are pivotal in the development of all-optical logic gates. The transition between SA and RSA are crucial in optoelectronic applications. In this study, we investigate the 5C2NA crystal, revealing its ability to exhibit both SA and RSA under the Z-scan technique with varying pump intensities. Switching properties observed in 5C2NA can be harnessed for applications such as all-optical logic gates, rapid optical switching, optical limiting, mode storage, among others.
Clarification of the transverse orbital angular momentum of spatiotemporal optical vortices
Authors: Porras Miguel A 
Published: July 2024

Abstract
Advances in the generation and the application of spatiotemporal optical vortices (STOV) are proceeding fast, but fundamental aspects of their nature remain obscure. Bliokh (2023 Phys. Rev. A 107 L031501) (PRA) and Porras (2023 Prog. Electromagn. Res.
177 95) (PIER) provide contradictory results on the transverse orbital angular momentum (OAM) carried by STOVs. We show that the results by Porras in PIER and by Bliokh in PRA refer to different STOVs and are all correct. In PIER, STOVs are elliptical at given cross section and time, or in space-time, but not in three-dimensional space. In PRA, STOVs are elliptical in space but not in space-time. This is evidenced from two dual, equivalent theories on the transverse OAM where a wave packet is seen in space-time evolving with propagation distance or in space evolving in time, that account for all values of the total, intrinsic and extrinsic OAM in PIERS and PRA. However, the intrinsic OAM with respect to the photon wave function center in PRA is not generally conserved, which advocates for the energy center in PIER as the STOV center. We argue that STOVs are generated in experiments to purportedly have elliptical symmetry in space-time. The values provided in PIER should then be taken as the reference for elliptical STOVs, and the theory therein to evaluate the transverse OAM of other wave packets. Hancock et al (2021 Phys. Rev. Lett.
127 193901; 2024 Phys. Rev. X 14 011031) erroneously attribute the transverse OAM of elliptical STOVs in space to the elliptical STOVs in space-time that they consider theoretically and can generate in their experiments.
Non-unique detailed constructions of Curzon-Ahlborn cycle on thermodynamic plane
Authors: Izumida Yuki 
Published: July 2024

Abstract
The Curzon-Ahlborn (CA) cycle is a paradigmatic model of endoreversible heat engines, which yields the so-called CA efficiency as the efficiency at maximum power. Due to the arbitrariness of the relationship between the steady temperature and the time taken for the isothermal process of the CA cycle, the constructions of the CA cycle on the thermodynamic plane are not unique. Here, we give some of the detailed constructions of the CA cycle on the thermodynamic plane, using an ideal gas as a working substance. It is shown that these constructions are equal to each other in the maximum power regime in the sense that they achieve the best trade-off between the work and the inverse cycle-time, known as the Pareto front in multi-objective optimization problems.
The African Regional Courts
Authors: Stone Sweet Alec , Sandholtz Wayne 
Published: July 2024

Abstract
This chapter examines the evolution of the African Union, the Economic Community of West African States, the East African Community, and the Southern African Development Community (SADC). The founding states did not establish these organizations as complete systems of transnational justice. Rather, international human rights courts have sought to render them more complete through their rulings. They have enforced rights in politically sensitive contexts, finding violations in cases involving torture and inhumane treatment, slavery, the incarceration of newspaper editors, the stifling of elections, among other violations. The African courts have engaged in continuous struggles to build their own effectiveness in the face of state resistance and indifference, which have, nonetheless, provoked backlash, regime exit, and attempts to curtail judicial authority. Indeed, states terminated the operations of the SADC, after only one ruling and finding of violation. Thus, the African courts perpetually confront the dilemma of effectiveness.
The Dilemma of Effectiveness
Authors: Stone Sweet Alec , Sandholtz Wayne 
Published: July 2024

Abstract
The states that founded human rights courts did not create fully fledged systems of transnational justice (STJs). The courts themselves have steadily sought to build complete STJs. Some of the human rights courts have consolidated their status as Trustees, while others are engaged in doing so. Judges place their reputations as good human rights jurists ahead of comforting the short-term interests of state officials in specific cases. The courts have embraced the objective of building effectiveness, perpetuating ongoing tensions with governments subject to their rulings. In response, member states have sometimes sought to constrain the courts or shut them down altogether. Still, the international human rights courts have sought to build the capacity to withstand backlash. Within each regime, courts have established dialogic relationships with domestic courts and other actors, which have become the foundation of a global commons for rights protection, with shared norms and techniques of adjudication.
