Authors: Liu Han , Ma Ronggui 
Published: August 2024

Abstract
The high-precision positioning of mileage piles on a digital map ensures accurate data for high-speed event releases, toll audits, and road condition monitoring. This paper introduces an efficient and automatic system for positioning highway mileage piles. The self-developed data acquisition system collects mileage pile images and road trajectory. Considering the limited variety of mileage piles, a Simplified-YOLOv5m (S-YOLOv5m) is proposed. Then a high-precision character detection network of S-YOLOv5m is proposed to enhance feature extraction and improve the accuracy of character detection on mileage piles. Thirdly, the end-to-end monocular distance measurement combines the target detection with the distance estimation, enabling simultaneous object detection and distance measurement. Fourthly, by combining with the geographical coordinates of the acquisition point, the direct solution to geodetic problems is applied to calculate the spatial coordinates of the mileage piles. Finally, the missing mileage piles are compensated for using the road curve and equal distance interpolation. The complete mileage piles and geographical information list of the inspection trajectory are output. Through a series of verification tests, the average positioning error of the mileage pile system is 1.265 m. The contribution of the automatic positioning system of mileage piles is to construct the relationship between mileage piles and geographical coordinates, match mileage piles with digital maps to realize the full-featured, real-scene, and high-dynamic management of road attributes.

Authors: Zhang Ran , Zhao Zhihong , Tao Xu , Yang Shaopu 
Published: August 2024

Abstract
In order to achieve robust fault diagnosis under varying conditions with limited labeled data, this study combines metric-based meta-learning with feature-based domain adaptation. It introduces a new approach for variable-condition bearing fault diagnosis using transfer relation networks. To enhance the network’s ability to generalize across different domains, the paper integrates local maximum mean discrepancy (LMMD) into the relation network architecture. LMMD aligns the data distributions of various classes between the source and target domains, effectively addressing distributional differences and improving model generalization. To accurately and swiftly extract meaningful fault features, the study proposes a lightweight feature extraction module based on Shuffle Attention (SA). This module employs depth-wise separable convolutions for efficiency and integrates SA after each convolutional layer to bolster feature representation. Finally, experiments on two bearing datasets under varying conditions validate the efficacy and superiority of the proposed model over alternative methods.
One-shot omnidirectional pressure integration through matrix inversion
Authors: Zigunov Fernando , Charonko John J 
Published: August 2024

Abstract
In this work, we present a method to perform 2D and 3D omnidirectional pressure integration from velocity measurements with a single-iteration matrix inversion approach. This work builds upon our previous work, where the rotating parallel ray approach was extended to the limit of infinite rays by taking continuous projection integrals of the ray paths and recasting the problem as an iterative matrix inversion problem. This iterative matrix equation is now ‘fast-forwarded’ to the ‘infinity’ iteration, leading to a different matrix equation that can be solved in a single step, thereby presenting the same computational complexity as the Poisson equation. We observe computational speedups of

when compared to brute-force omnidirectional integration methods, enabling the treatment of grids of

points and potentially even larger in a desktop setup at the time of publication. Further examination of the boundary conditions of our one-shot method shows that omnidirectional pressure integration implements a boundary condition where the boundary points are treated as interior points to the extent that information is available. Finally, we show how the method can be extended from the regular grids typical of particle image velocimetry to the unstructured meshes characteristic of particle tracking velocimetry data.
Preparation and performance study of silicon modified polyurethane-based magnetorheological elastomeric polishing pad
Authors: Hu Da , Long Haotian , Lu Jiabin , Li Huilong , Zeng Jun , Yan Qiusheng 
Published: August 2024

Abstract
By employing magnetorheological elastomers (MREs) as polishing pads for chemical mechanical polishing (CMP), the magnetorheological properties are utilized to effectively control the flexible removal of materials in CMP. This study presents a method for preparing a silicon modified polyurethane (SPU)-based MRE polishing pad, aimed at demonstrating improved magnetorheological properties while preserving mechanical properties. The SPU-based MRE polishing pad was synthesized through the copolymerization of hydroxypropyl silicone oil and polyurethane prepolymers, with subsequent evaluation of its mechanical properties and polishing performance. Fourier transform infrared analysis confirmed the successful incorporation of the soft polydimethylsiloxane main chain from organosilicon into the polyurethane main chain, forming a soft segment that intertwines with the polyurethane main chain to create a soft-hard segment crosslinked structure. Comparison to polyurethane (PU)-based MRE, SPU exhibits significantly reduced hardness but improved wear resistance, as well as enhanced resistance to acid and alkali corrosion. Due to the presence of a soft matrix, SPU shows better magnetorheological effects (MR Effects) than PU-based MRE. Under a magnetic field intensity of 845 mT, the MR Effect of PU-based MRE is only 18%, while Si-15.96 and Si-16.79 SPU-based MREs can reach 84% and 110%, respectively. Although the material removal rate (MRR) of single-crystal SiC decreases after polishing with SPU compared to PU-based MRE, a higher surface quality is achieved, and the glazing degree of the polishing pad is significantly reduced. In the magnetic field-assisted polishing of single crystal SiC, the MRR increased by 38.4% when polished with an SPU-based MRE polishing pad, whereas the MRR was only 8.7% when polished with a PU-based MRE polishing pad. This study provides further evidence for the development and application of MRE in CMP.
Higher-order interactions and zero-determinant strategies in the public goods game
Authors: Li Junchi 
Published: August 2024

Abstract
Since the ingenious discovery of zero-determinant (ZD) strategies by Press and Dyson, many efforts have been devoted to the evolutionary performance of ZD strategies. Recently, the effects of higher-order interactions on evolutionary games have attracted widespread interests, whereas it remains unknown how higher-order interactions affect the evolutionary performance of ZD strategies. This paper focuses on the role of higher-order interactions on evolutionary ZD strategies in iterated public goods game, where the baseline payoff is a key parameter to describe nodes’ extent of reciprocity in both first-order and second-order interactions. Through the adaptive-like dynamics, we found that there is a critical value of each network, above which the networked game will converge to a consensus state where all the nodes obtain the same payoff. This critical value is significantly affected by the relative strength of higher-order interactions with a U-shaped trend. Numerical simulations are carried out to explore how the network structures affect the dynamics. The results in networks with different sizes indicate that networks with higher average degree are more easily to converge to the consensus state. The simulations on a real-world network further support the theoretical conclusions.

Published: August 2024

Abstract
Mode pairing quantum key distribution (MP-QKD) overcomes the repeaterless bound without requiring phase locking and phase tracking. However, MP-QKD still assumes that the light source is trusted, which can present challenges in practical deployments and potentially introduce security vulnerabilities. In this paper, we propose a light source monitoring (LSM) scheme that guarantees the security of MP-QKD with the untrusted light sources. The simulation results demonstrate that, when considering untrusted light sources, the performance of MP-QKD with the LSM scheme remains nearly identical to that of ideal MP-QKD, even in the presence of the source fluctuations. Furthermore, we simplify some of the complex integration calculations involved in simulating the observed quantities of MP-QKD, which reduces the running time of the parameter optimization procedure.

Abstract
The interplay between superconductivity and magnetism is an important subject in condensed matter physics. EuFe2As2-based iron pnictides could offer an interesting plateau to study their relationship that has attracted considerable attention. So far, two magnetic phase transitions were observed in EuFe2As2-based crystal, which were deemed to originate from the itinerant Fe moments (~190 K) and the localized Eu2+ moments (~19 K), respectively. Here, we systematically studied the heat capacity for the EuFe2(As

Tunable thermal conductivity of surface phonon polaritons in SiC thin film
Authors: Huang Congliang , Wang Yibo , Wang Xiaodong 
Published: August 2024

Abstract
As an additional heat carrier besides phonons and electrons, the surface phonon polariton (SPhPs) possesses a large potential to increase the thermal conductivity. In this work, the influences of SPhP frequency, film thickness and film permittivity on the SPhP-contributed thermal conductivity of SiC thin films were probed. Results show that: there are two frequency zones which could lead to a much high thermal conductivity, i. e. the frequency which approaching zero and the frequency in singularity zone. The thermal conductivity decreases with the increase of the film thickness, following a power-function relationship, and a thin film with a thickness of 10-nm could have a thermal conductivity higher than

W·m−1·K−1. However, the experimental observation of this high thermal conductivity is still difficult because of the size effect of the film length. The thermal conductivity will increase with the decrease of the imaginary part of the film permittivity and/or increase of the real part of the film permittivity, and there is approximately a reciprocal dependence of thermal conductivity on the imaginary part of the film permittivity. The thermal conductivity could be tuned by several times with tailoring its permittivity through adding fillers in it or adding dopant in it. This work provides some potential methods to tune the SPhP thermal conductivity in SiC thin film, which could help its application in microscale heat dissipation.
A dual-band bandpass filter based on hybrid ESPPs-SIW structure with ultra-wide upper stopband suppression
Authors: Chen Kunhong , Wen Pin , Wang Chenao , Huang Xiaojie , Liu Foxiang , Xu Kai-Da 
Published: August 2024

Abstract
In this paper, a new bandwidth-controllable dual-band bandpass filter (BPF) based on hybrid effective surface plasmon polaritons (ESPPs) and substrate integrated waveguide (SIW) structure is presented. It consists of three parts, where a dual-band filtering part is realized by a two-layer SIW and an air cavity located on the top of SIW, and two traditional SSPPs low-pass filtering parts are introduced for wide stopband suppression. According to effective-medium theory and structural dispersion, different widths and relative permittivities of the SIW and air cavity are used to provide flexible cutoff frequencies of the ESPPs-SIW structure, thus exhibiting independently controllable bandwidth. The simulation results reveal that the presented dual-band BPF has outstanding filtering performance and ultra-wide upper stopband suppression level. The upper stopband can be extended up to 21.4 GHz (8.5f
0) with a suppression level of −20 dB, where f
0 is the center frequency of the first passband (i.e., 2.52 GHz). The measurement results are in good agreement with the simulation results, which verifies the correctness of our design concept and method.

Authors: Ghanavati Mohammad , Emami Farzin , Karami Mohammad Azim 
Published: August 2024

Abstract
This paper proposes a novel plasmonic temperature and refractive index (RI) sensor that utilizes a Metal-Insulator-Metal (MIM) waveguide with two neighboring hexagonal cavities working based on Surface Plasmon Resonance (SPR). The study demonstrates that the structural parameters, including coupling distance and the number of gratings, have a substantial influence on both Full Width at Half Maximum (FWHM) and the transmission spectrum. The findings of this study demonstrated a maximum temperature sensitivity of 0.91 nm.°C−1 for carbon disulfide and a corresponding maximum temperature figure of Merit (FoM) of 0.0180 °C−1 for chloroform. The RI-sensitivity (RIS) of this sensor is found to be 1147.22 nm per RI unit (RIU) as well as its FoM is 37.1 RIU−1. Furthermore, the sensor exhibits the ability to quantify blood glucose concentration with a maximum sensitivity of 0.136 nm.g−1.L and measure blood plasma concentration with a maximum sensitivity of 0.211 nm.g−1.L. This sensor differentiates the RI between healthy and cancer cells and can be utilized to identify both healthy red blood cells and those infected with malaria. Adding gratings to the waveguide and within the hexagonal cavities has a significant impact on the transmission intensity. The proposed plasmonic sensor can be used in optoelectronics, cancer cell sensors and photonic circuits.
A tunable chiral metasurface useable in terahertz imaging and wavefront shaping
Authors: Zhang Xin , Yang Shuang , Gao Yachen 
Published: August 2024

Abstract
We proposed a tunable chiral metasurface comprising a reflective bottom layer of gold, a dielectric layer of polyimide, and a structural top layer of gold-graphene. Its main properties were studied via numerical simulations conducted using CST Studio Suite. The results indicate that, based on the chiral metasurface, we achieved dual-band circular dichroism of −0.5 and 0.77 at 0.9 THz and 1.06 THz, respectively, and complementary near-field imaging applications were realized by tuning the Fermi level (E
f
) of graphene. Subsequently, exploiting the exceptional selective characteristics of circularly polarized waves using a chiral metasurface, eight chiral phase-gradient metasurfaces were constructed by rotating the chiral structure. Moreover, based on the Pancharatnam-Berry phase principle, tunable wavefront shaping applications were further realized, including anomalous reflection, vortex beams, and focusing. In anomalous reflection, the reflection angles for left-circularly polarized (LCP) and right-circularly polarized (RCP) incidences are opposite when adjusting the E

f
of graphene. For example, when the graphene E
f
is 0 eV and the LCP wave is incident at 0°, the reflection angle is −18°. Conversely, when the graphene E
f
is 1 eV and the RCP wave is incident at 0°, the reflection angle is 18°. In the application of vortex beams, by adjusting the E

f
of graphene, we achieved vortex beams with opposite topological charges under different circularly polarized incidences. In the focusing application, the incident LCP and RCP can achieve focusing and defocusing, respectively. And the graphene E

f
can dynamically control the focusing efficiency at the incident LCP, increasing it from 13.63% to 44.84%.

Published: August 2024

Abstract
This study aims to synthesize biocomposite by combining banana stem activated carbon (AC) and ZnO Nanoparticles (NPs) to evaluate their adsorption potential towards hexavalent chromium (Cr (VI)) (20 mg/L). The AC used was successfully synthesized by an impregnation method using phosphoric acid (H3PO4) for 24 h, followed by a carbonization method. ZnO NPs were synthesized using the direct precipitation method using zinc acetate dihydrate (0.2 M) and KOH (0.4 M) as precursors. The AC/ZnO NPs biocomposite was fabricated using the mechanical alloying method at a frequency of 10 Hz for 30 min. The FTIR results show that both adsorbents, namely pure AC and AC/ZnO NPs have abundant functional groups. XRD results show the adsorbent is amorphous with pure AC at 89.95% and AC/ZnO NPs biocomosite at 56.49%. SEM results showed that the morphology of AC resembled crushed bovine bone marrow, and the morphology of ZnO NPs showed a marshmallow-like shape. The UV–vis spectrometer test results show that at the absorption peak of 350 nm the Cr (VI) removal efficiency slowly decreases and disappears at a dose variation of 1.5 g pure AC, 2 g biocomposite AC/ZnO NPs, and 2 g pure AC with Cr (VI) removal efficiency of 99.61%, 99.64%, and 99.83% respectively. Finally, we can report that the high degradation ability for Cr (VI) can be related to thesharp peak of –C=O group, reduced

Turbulence compensation with pix-to-pix generative adversarial networks in vector vortex beams
Authors: Zhang Zhi , Xie Xiaoping , Si Jinhai , Wang Wei , Jia Shuaiwei , Gao Duorui 
Published: August 2024

Abstract
Orbital angular momentum (OAM) has significantly propelled free space optical communication (FSOC) towards achieving ultra-large transmission capacities, but mode-crosstalk in atmospheric turbulence limits its application. Here, we propose a proof-of-concept turbulence compensation approach utilizing pix-to-pix generative adversarial networks (pix2pixGAN) that does not rely on the wavefront sensor. The model captures the complex relationships between distorted optical fields and phase screens through extensive training, after which the phase screen is directly recovered from the well-trained model by identifying the corresponding distorted image to compensate for distortions. Using this model, the Strehl ratio improvement is measured at 35.7%, 8.9%, and 1.7% under three distinct turbulence conditions, respectively. Furthermore, the recognition of vector vortex beams (VVBs) integrating with the pix2pixGAN significantly improves average mode accuracy from 2% to over 99%. Additionally, the exploration of VVB-based communication further elucidates pix2pixGAN's role in enhancing communication quality. These findings suggest a potential advancement in developing a novel neural network-based strategy to compensate for transmission distortions under intense turbulence.

These results are derived by applying the Karmarkar condition, which creates wormhole geometry that meets the necessary conditions and connects two asymptotically flat areas of spacetime.

These models are then confined to be compatible with current experimental evidence. Further, the energy conditions of the wormhole are geometrically probed, and it is proven that they adhere to the null energy conditions in areas close to the throat. Moreover, the fascinating aspect of this study involves conducting an examination and comparison of evolving wormhole geometries in the vicinity of the throat in our chosen models, utilizing two- and three-dimensional graphical representations. We observe that our shape function acquired through the Karmarkar technique yields validated wormhole configurations with even less exotic matter, correlating to the proper choice of
