Authors: Gao Zhangang , Yang Zihao , Xu Mengchen , Yang Hualin , Deng Fang 
Published: October 2024

Abstract
Due to the large randomness of tire appearance defect size and the complex and diverse defect shapes, the existing target detection algorithm is prone to missing and misidentifying targets, the accuracy is limited, and the detection model is large, which is not conducive to deployment on embedded devices. In this paper, the efficient multi-scale convolution (EMC) mode is proposed, and the C2f-EMC module is designed on this basis, which improves the network structure of YOLOv8, improves the accuracy of tire appearance defect detection, and reduces the number of parameters in the model. EMC convolution first divides the input feature images into four parts on average and carries out multi-scale convolution with convolution cores of 1 × 1, 3 × 3, 5 × 5 and 7 × 7 sizes respectively. Then, the obtained results are stacked, and cross-channel feature fusion is realized by point-by-point convolution. After determining the network structure of C2f-EMC, the best improvement position of C2f-EMC module is determined through comparative experiments. Experiments show that after the above improvements, the parameter number of the model is reduced by 4.85%, the calculation amount by 2.82%, the model size by 4.44%, the recall rate by 2.8%, the mAP50 by 1.0%, the mAP50-95 by 1.3%, and the F1 by 2%. The defect detection task can be completed more accurately and the model size requirements of embedded devices can be better met.
Sub-∘C-precision temperature imaging using phase-shift luminescence thermometry
Authors: López Bonilla Joel , Beyrau Frank , Fond Benoit 
Published: October 2024

Abstract
This work explores the potential of luminescence thermometry to provide temperature imaging with high temperature resolution using the phase-shift method. Phosphor thermometry has been widely used for temperature imaging, especially with the decay-time method. However, the phase-shift method was rarely used. In this approach, excitation is modulated in time, and due to the temperature-dependent luminescence dynamics of the painted luminescent probe, the emission waveform is phase-shifted with respect to the excitation waveform. Initially, a parametric study was performed on the effect of excitation waveform frequency and shape, based on a millisecond-decay time phosphor. The study found that the best precision is achieved with a square waveform at a frequency such that the phase shift is

at the target temperature. Then, this method was compared with the well-established decay-time method. Phase-shift method offered a three-fold improvement in temperature precision under identical peak excitation power. Finally, two-dimensional measurements were demonstrated on a temperature-controlled plate using a high speed CMOS camera, and an LED illumination. A temperature precision of 0.13 ∘C was obtained at a temporal resolution of 0.25 s and a spatial resolution of around 1 mm, due to a pre-processing binning of 7 by 7 pixels. This technique can be used as a robust alternative to infrared thermometry to probe the thermal processes with small temperature differences.

Published: October 2024

Abstract
Extending optical nonlinearity into the extremely weak light regime is at the heart of quantum optics, since it enables the efficient generation of photonic entanglement and implementation of photonic quantum logic gate. Here, we demonstrate the capability for continuously tunable single-photon level nonlinearity, enabled by precise control of Rydberg interaction over two orders of magnitude, through the use of microwave-assisted wave-function engineering. To characterize this nonlinearity, light storage and retrieval protocol utilizing Rydberg electromagnetically induced transparency is employed, and the quantum statistics of the retrieved photons are analyzed. As a first application, we demonstrate our protocol can speed up the preparation of single photons in low-lying Rydberg states by a factor of up to

Cosmological implications on two fluids model universe with parametrization of Hubble parameter in Lyra manifold
Authors: Sabanam Syed , Singh Kangujam Priyokumar 
Published: October 2024

Abstract
In this research, we explore the cosmological implication on five-dimensional FRW cosmological model for k = 0 in presence of two perfect fluids: ordinary baryonic fluid and an interacting dark energy in the context of Lyra’s manifold. We obtain an exact solution of the field equations by assuming the parametrization of the Hubble parameter H(a) = τ(1 + a
−ν
), where a is a scale factor and τ > 0, ν > 1 are the arbitrary constants. This results in a universe model with a transition from a previously decelerating universe to the current accelerating universe, characterized by a time-dependent deceleration parameter. Moreover, we have used 46 observational Hubble data sets to restrict the parameters of our suggested model. Some cosmological parameters have been examined about the nature of the proposed model universe. It is shown that our model can be considered a realistic one.
Effects of DM and KSEA interactions on entanglement, Fisher and Wigner-Yanase information correlations of two XYZ-Heisenberg-qubit states under a magnetic field
Authors: Gaidi S , Slaoui A , Mohamed A-B A , EL Falaki M , Ahl Laamara R 
Published: October 2024

Abstract
We employ entanglement negativity, local quantum uncertainty (LQU), and local quantum Fisher information (LQFI) to characterize thermal entanglement between two XYZ-Heisenberg-qubit states under the influence of Dzyaloshinsky-Moriya(DM) and Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEA) interactions, as well as a magnetic field and thermal equilibrium temperature. A comparative examination reveals similar behaviors among these correlation measures. For the antiferromagnetic scenario, we observe that increasing the DM interaction parameter D

z
enhances thermal entanglement. Conversely, in the ferromagnetic case, the behavior of thermal entanglement differs with varying D

z
. Additionally, employing Kraus operators, we explore the performance of these quantifiers under decoherence. Notably, LQFI exhibits greater robustness than negativity and LQU, even displaying a frozen phenomenon at some time under dephasing effects.
Entanglement manipulation through multicore fibres
Authors: Marconi Carlo , Fanella Elena , Bacco Davide , Zavatta Alessandro 
Published: October 2024

Abstract
Multicore fibres are recently gaining considerable attention in the context of quantum communication, where their capability to transmit multiple quantum states along different cores of the same channel makes them a promising candidate for the implementation of scalable quantum networks. Here, we show that multicore fibres can be effectively used not only for the scope of communication but also for the manipulation of entangled states. Exploiting the formalism of completely positive trace-preserving maps, we describe the action of a multicore fibre as a quantum channel and investigate the propagation of a transmitted state under the effect of decoherence and inter-core crosstalk. Then, we propose a novel protocol for the manipulation of the entanglement where, starting from a maximally entangled state of two qudits, we use a multicore fibre to create new families of mixed entangled states. Notably, the presence of crosstalk is fundamental for the generation of such states.

curvature-squared corrections on Langevin diffusion coefficients*
Authors: Zhou 周 Qi 琪 , Zhang 张 Ben-Wei 本威 
Published: October 2024

Abstract
The effect of finite coupling corrections to the Langevin diffusion coefficients on a moving heavy quark in the Super Yang-Mills plasma was investigated. These corrections are related to curvature squared corrections in the corresponding gravity sector. We compared the results of both longitudinal and perpendicular Langevin diffusion coefficients with those for

=4 Super Yang-Mills plasma. It was observed that the curvature-squared corrections influence the Langevin diffusion coefficients, and the corrections for both Langevin diffusion coefficients demonstrate the dependence on the velocity of the moving heavy quark and the specifics of the higher derivative correction. In addition, we conducted calculations for the Langevin diffusion coefficients of a moving heavy quark within the Gauss-Bonnet background.
ISMGCC: Finding Gas Structures in Molecular Interstellar Medium Using Gaussian Decomposition and Graph Theory

Published: October 2024

Abstract
Molecular line emissions are commonly used to trace the distribution and properties of molecular Interstellar Medium. However, the emissions are heavily blended on the Galactic disk toward the inner Galaxy because of the relatively large line widths and the velocity overlaps of spiral arms. Structure identification methods based on voxel connectivity in Position-Position-Velocity (PPV) data cubes often produce unrealistically large structures, which is the “over-linking” problem. Therefore, identifying molecular cloud structures in these directions is not trivial. We propose a new method based on Gaussian decomposition and graph theory to solve the over-linking problem, named InterStellar Medium Gaussian Component Clustering (ISMGCC). Using the Milky Way Imaging Scroll Painting (MWISP) 13CO(1–0) data in the range of 13.°5 ≤ l ≤ 14.°5, ∣b∣ ≤ 0.°5, and −100 ≤ V
lsr ≤ +200 km s−1, our method identified three hundred molecular gas structures with at least 16 pixels. These structures contain 92% of the total flux in the raw data cube and show single-peaked line profiles on more than 93% of their pixels. The ISMGCC method could distinguish gas structures in crowded regions and retain most of the flux without global data clipping or assumptions on the structure geometry, meanwhile, allowing multiple Gaussian components for complicated line profiles.
A smooth switching strategy for steady-state operation control and fault transient control of doubly fed induction generator
Authors: Zhuang Shenglun , Kong Xiangmei , Qu Huixing , Sun Sujuan 
Published: October 2024

Abstract
As the proportion of wind power generation systems in power systems continues to rise, their dynamic response during system malfunctions has gained significant importance. As the grid short-circuit ratio continues to decrease, traditional fault ride-through algorithms for wind power generators may no longer be applicable. This is evidenced by voltage oscillations under significant disturbances and overvoltage issues during low-voltage ride-through, which are further aggravated during asymmetric fault conditions. Therefore, this paper focuses on the low-voltage ride-through issues of doubly fed induction wind power generators in weak power grids. It investigates the steady-state operation and transient control schemes and proposes a smooth transition strategy for steady-state and fault transient operations of doubly fed wind power generators. This approach guarantees the synchronization of active and reactive power, mitigates steady-state reactive power imbalance, and prevents voltage fluctuations triggered by recurring low-voltage ride-through occurrences. Furthermore, during fault recovery, a ramped active power restoration approach is employed to mitigate the coupling of active and reactive power introduced by the phase-locked loop, enabling rapid and stable restoration of active and reactive power outputs. As a result, superior dynamic performance is achieved during both symmetric and asymmetric fault processes. Finally, the superiority of the proposed smooth transition strategy under different fault scenarios is validated through simulations with the RTLAB platform.

Abstract
It is necessary to obtain information regarding the life history and stock status of the yellow-striped goatfish (Upeneus vittatus) in the coastal waters of Lebak and Sukabumi, Indonesia. This study aims to determine the stock status of U. vittatus in the coastal waters of Lebak and Sukabumi based on their life history parameters and length-based spawning potential ratio (LB-SPR). Eight hundred seventy-four samples were collected from Binuangeun, Palabuhanratu Nusantara, and Ciwaru Fishing Ports. The monthly length frequency data were obtained from July to December 2022. The results show that the Von Bertalanffy growth parameter was Lt=254(1-e−(0.58(t+0.154)) for males, Lt=239(1-e−(0.42(t+0.221)) for females, and Lt = 258(1-e−(0.37(t+0.246)) for both. The mature gonads of U. vittatus were mostly obtained from October to December. The length of first maturity L50 and L95 were 158 mm and 236 mm for males and 149 mm and 229 mm for females, respectively. The exploitation rate (E) on male, female, and combined U. vittatus revealed that E values exceed 0.5 or are overexploitation. The estimated SPR of U. vittatus was 23%, lower than the target reference point of 40%. Therefore, U. vittatus was fully exploited in the coastal waters of Lebak and Sukabumi.

Abstract
Macrozoobenthos live sedentary at the bottom of the waters with slow movements and a relatively long-life cycle, and they are able to respond continuously to changes in water conditions. The aim of this study is to analyze macrozoobenthic ecology as an indicator of water quality at Margagiri-Grenyang coastal waters, Banten Bay. The study was carried out for 5 months from July-November 2022 with six stations. Macrozoobenthos samples were taken using Petersen Grab, and water quality was measured in situ and ex situ. Data analysis was conducted to estimate abundance, biological indices, PCA, similarity index, and AMBI and M-AMBI. The macrozoobenthos at the study site were composed of six phyla (Molusca, Annelida, Echinodermata, Arthropoda, Hoplonemertea, and Nemertea). The highest density of the marozoobenthos was found in July (3178 ind/m2), with moderate diversity (H′) (2.535–2.758), medium-high evenness (E) (0.742–0.833), and low dominance (C) indices (0.157–0.241). Based on PCA, the distribution of macrozoobenthos is influenced by turbidity and TSS parameters. AMBI and M-AMBI analysis showed that macrozoobenthos undisturbed and indicated by good-high water quality.

Abstract
Blue swimming crab (Portunus pelagicus) is the main fishery commodity in the Madura Strait, Pamekasan Regency. The sustainability of the crab depends on the suitability of the habitat and the availability of food in the waters. This study aims to analyze the food composition and trophic niches of blue swimming crab in the Madura Strait, Pamekasan Regency. Sampling was conducted using the simple random sampling technique. The analysis included composition of the collection based on length frequency distribution, gastric fullness index, trophic niche area, food niche overlap, crab food composition, and growth (carapace width-weight relationship, and condition factor). The results of the index study showed that the index of stomach content of the female was generally greater than that of the male. Blue swimming crab is classified as a carnivore with the main food being fish. The overlap of the niches of male and female crabs of 0.9328 indicates a high level of competition for food. The male crab has a negative allometric growth pattern, while the female crab has a positive allometric growth pattern. The condition of the crab factor in each month of observation is greater than 0.5 indicating the availability of food and water conditions suitable for crab life.

Abstract
The Redbelly yellowtail fusilier with the local name Ekor Kuning (Caesio cuning) is a reef fish species found in the waters of the Indo-West Pacific. In Indonesia, it is an economically important fish and is dominantly caught by gill nets, traps and handlines. The intensity of fishing that is carried out continuously is feared to threaten the stock of the species in nature. In order to make its use sustainable, this study attempts to evaluate population dynamics and reproductive biology. The study was carried out in the Kendari waters of the Banda Sea, Indonesia, between April and December 2018. The findings indicated that this fish’s length distribution covered a range of 11,6-29,0 cm FL and the growth pattern was isometric with the length-weight relationship equation W=0,0206L3,0612. The spawning season peaked in November, and the sex ratio did not deviate considerably from 1:1. The length at first maturity (Lm = 21,73 cm FL) was longer than the length at first capture (Lc =15,5 cm FL) The VBGE for yellowtail was Lt
= 30,45 [1 – e−0,89(t+0,171)]. The value of mortality due to capture (F = 2,19 per year) is greater than natural mortality (M = 0,44 per year). The exploitation rate (E) was recorded as 0,72 per year and the SPR value is 0,22 per year. Based on these parameters, it indicates that the level of exploitation of Caesio cuning in Kendari waters is in overfished so that management needs to be implemented by limiting the smallest fish size that can be caught and to reduce fishing operations during the spawning season.
