Yuqing Ma — 2025-09-26

With the development of composite materials, their lightweight and high-strength characteristics have caused more widespread use from aerospace applications to automotive and rail transportation sectors, significantly reducing the energy consumption during the operation of EMUs (Electric Multiple Units). This study aims to explore the application of composite materials in the lightweight design of EMU front skirts and proposes a design method based on three-dimensional Hashin failure criteria and the Cheetah Optimizer (CO) to achieve maximum lightweight efficiency. The UMAT subroutine was developed based on the three-dimensional Hashin failure criteria to calculate failure parameters, which were used as design parameters in the CO. The model calculations and result extraction were implemented in MATLAB, and the Cheetah Optimizer iteratively determined the optimal laminating angle design that minimized the overall failure factor. After 100 iterations, ensuring structural integrity, the optimized design reduced the weight of the skirt panel by 60% compared to the original aluminum alloy structure, achieving significant lightweight benefits. This study provides foundational data for the lightweight design of EMUs.

Correlation Analysis Between Investor Sentiment and Stock Price Fluctuations Based on Large Language Models

Guohua Ren — 2025-10-15

The efficient market hypothesis in traditional financial theory struggles to explain the short-term irrational fluctuations in the A-share market, where investor sentiment fluctuations often serve as the core driver of abnormal stock price movements. Traditional sentiment measurement methods suffer from limitations such as lag, high misjudgment rates, and the inability to distinguish confounding factors. To more accurately explore the dynamic correlation between investor sentiment and stock price fluctuations, this paper proposes a sentiment analysis framework based on large language models (LLMs). By constructing continuous sentiment scoring factors and integrating them with a long short-term memory (LSTM) deep learning model, we analyze the correlation between investor sentiment and stock price fluctuations. Empirical results indicate that sentiment factors based on large language models can generate an annualized excess return of 9.3% in the CSI 500 index domain. The LSTM stock price prediction model incorporating sentiment features achieves a mean absolute percentage error (MAPE) as low as 2.72%, significantly outperforming traditional models. Through this analysis, we aim to provide quantitative references for optimizing investment decisions and preventing market risks.

Flow velocity uniformity of the microchannel plate is a major factor affecting the performance of microchannel devices. In order to improve the velocity distribution uniformity of the microchannel plate, we designed two new microchannel structures: V-type and A-type.

The V-type and A-type microchannel plates had a more uniform velocity distribution compared to the Z-type microchannel plate. The final result showed that it is beneficial for the V-type microchannel plate to obtain a more uniform velocity distribution when the manifold structure parameters are X_in = -1, X_out = 0, Y_in = 10, Y_out = 6, H_in = 4, H_out = 1, and R = 0.5.

Meilin Song — 2025-10-15

This study focuses on the fluorescent thermometric properties of CaMoO4:5%Tb³⁺ under different temperature excitations. At the detection wavelength of 544 nm, with the temperature varying from 293 K to 563 K, there is a broadband absorption peak in the range of 250 nm to 350 nm. The results indicate that this phenomenon is caused by the superposition of the 4f-5d transition of Tb³⁺ and the O^2--Mo⁶⁺ charge transfer. It is considered that as the temperature rises, the luminescent intensity of the material shows an obvious continuous decreasing trend, which reflects a significant luminescent thermal quenching trend; thus, this quenching belongs to the “strong coupling” type. Based on the excitation spectrum results, two excitation wavelengths, 312 nm and 338 nm, were specifically selected to excite the samples, which correspond to the top of the charge transfer band, the redshift intersection of the charge transfer band, and the edge of the charge transfer band at 293 K, respectively.

Keran Yu — 2025-10-21

With the widespread application of 3D visualization in digital exhibition halls and virtual reality, achieving efficient rendering and high-fidelity presentation has become a key challenge. This study proposes a hybrid point cloud generation method that combines traditional sampling with 3D Gaussian splatting, aiming to address the issues of rendering delay and missing details in existing 3D displays. By improving the OBJ model parsing process and incorporating an adaptive area-weighted sampling algorithm, we achieve adaptive point cloud generation based on triangle density. Innovatively, we advance the ellipsoidal parameter estimation process of 3D Gaussian splatting to the point cloud generation stage. By establishing a mathematical relationship between the covariance matrix and local curvature, the generated point cloud naturally exhibits Gaussian distribution characteristics. Experimental results show that, compared to traditional methods, our approach reduces point cloud data by 38% while maintaining equivalent visual quality at a 4096×4096 texture resolution. By introducing mipmap texture optimization strategies and a GPU-accelerated rasterization pipeline, stable rendering at 60 frames per second is achieved in a WebGL environment. Additionally, we quantize and compress the spherical harmonic function parameters specific to 3D Gaussian splatting, reducing network transmission bandwidth to 52% of the original data. This study provides a new technical pathway for fields requiring high-precision display, such as the digitization of cultural heritage.

Huiwen Xu — 2025-10-15

This paper designs a high-frequency stable wireless amplitude modulation (AM) system based on a Pierce circuit. The system utilizes an oscillator and comparator to generate a 20 kHz square wave with an adjustable duty cycle, combined with a 41 MHz carrier wave produced by a passive crystal oscillator Pierce circuit. A 100% modulation index amplitude modulation is achieved through the AD835 multiplier.

Upon reception, the signal undergoes two-stage high-frequency amplification before passing through a Schottky diode envelope detector. The NE5532 shaping circuit then restores the square wave. Experimental results demonstrate reliable 11-meter transmission with carrier frequency deviation < 0.75% and demodulation error < 1%.

An Image Manipulation Localization Method Based on Dual-Branch Hybrid Convolution

Chengliang Yan — 2025-10-17

In existing image manipulation localization methods, the receptive field of standard convolution is limited, and during feature transfer, it is easy to lose high-frequency information about traces of manipulation. In addition, during feature fusion, the use of fixed sampling kernels makes it difficult to focus on local changes in features, leading to limited localization accuracy. This paper proposes an image manipulation localization method based on dual-branch hybrid convolution. First, a dual-branch hybrid convolution module is designed to expand the receptive field of the model to enhance the feature extraction ability of contextual semantic information, while also enabling the model to focus more on the high-frequency detail features of manipulation traces while localizing the manipulated area. Second, a multi-scale content-aware feature fusion module is used to dynamically generate adaptive sampling kernels for each position in the feature map, enabling the model to focus more on the details of local features while locating the manipulated area. Experimental results on multiple datasets show that this method not only effectively improves the accuracy of image manipulation localization but also enhances the robustness of the model.

Qian Xu — 2025-10-17

This paper proposes SW-YOLO (StarNet Weighted-Conv YOLO), a lightweight human pose estimation network for edge devices. Current mainstream pose estimation algorithms are computationally inefficient and have poor feature capture capabilities for complex poses and occlusion scenarios. This work introduces a lightweight backbone architecture that integrates WConv (Weighted Convolution) and StarNet modules to address these issues. Leveraging StarNet’s superior capabilities in multi-level feature fusion and long-range dependency modeling, this architecture enhances the model’s spatial perception of human joint structures and contextual information integration. These improvements significantly enhance robustness in complex scenarios involving occlusion and deformation. Additionally, the introduction of WConv convolution operations, based on weight recalibration and receptive field optimization, dynamically adjusts feature importance during convolution. This reduces redundant computations while maintaining or enhancing feature representation capabilities at an extremely low computational cost. Consequently, SW-YOLO substantially reduces model complexity and inference latency while preserving high accuracy, significantly outperforming existing lightweight networks.

Gated Attention-Enhanced Informer

Yufeng Zhang — 2025-10-17

The Informer model leverages its innovative ProbSparse self-attention mechanism to demonstrate significant performance advantages in long-sequence time-series forecasting tasks. However, when confronted with time-series data exhibiting multi-scale characteristics and substantial noise, the model’s attention mechanism reveals inherent limitations. Specifically, the model is susceptible to interference from local noise or irrelevant patterns, leading to diminished focus on globally critical information and consequently impairing forecasting accuracy. To address this challenge, this study proposes an enhanced architecture that integrates a Gated Attention mechanism into the original Informer framework. This mechanism employs learnable gating functions to dynamically and selectively impose differentiated weighting on crucial temporal segments and discriminative feature dimensions within the input sequence. This adaptive weighting strategy is designed to effectively suppress noise interference while amplifying the capture of core dynamic patterns. Consequently, it substantially strengthens the model’s capability to represent complex temporal dynamics and ultimately elevates its predictive performance.

IMLMA: An Intelligent Algorithm for Model Lifecycle Management with Automated Retraining, Versioning, and Monitoring

Yu Cao — 2025-10-21

With the rapid adoption of artificial intelligence (AI) in domains such as power, transportation, and finance, the number of machine learning and deep learning models has grown exponentially. However, challenges such as delayed retraining, inconsistent version management, insufficient drift monitoring, and limited data security still hinder efficient and reliable model operations. To address these issues, this paper proposes the Intelligent Model Lifecycle Management Algorithm (IMLMA). The algorithm employs a dual-trigger mechanism based on both data volume thresholds and time intervals to automate retraining, and applies Bayesian optimization for adaptive hyperparameter tuning to improve performance. A multi-metric replacement strategy, incorporating MSE, MAE, and R², ensures that new models replace existing ones only when performance improvements are guaranteed. A versioning and traceability database supports comparison and visualization, while real-time monitoring with stability analysis enables early warnings of latency and drift. Finally, hash-based integrity checks secure both model files and datasets. Experimental validation in a power metering operation scenario demonstrates that IMLMA reduces model update delays, enhances predictive accuracy and stability, and maintains low latency under high concurrency. This work provides a practical, reusable, and scalable solution for intelligent model lifecycle management, with broad applicability to complex systems such as smart grids.

The relevant basic data of the bursary evaluation is stored on the chain to solve the problem of easy falsification of data in the evaluation process. At the same time, the evaluation results of the student bursary are uploaded to the chain to realize the traceability of historical data. In addition, the improved XGBoost algorithm is used to intelligently analyze and evaluate the basic data of students, and objectively give the student a bursary grade, which realizes the intelligence and scientific nature of the evaluation process and ensures the accuracy of the evaluation results. The experimental results prove that the model proposed in this paper has an accuracy rate of about 6% higher than that of the traditional XGBoost model, which has higher evaluation accuracy, throughput, and time efficiency. The method proposed in this paper is suitable for the evaluation of scholarships and bursaries in the student management system of colleges and universities.

In this paper, the topological structure of the vehicle wireless network M2M (Machine to Machine) is used as the experimental research model, and four kinds of light coefficients are set as factors affecting the experimental results, namely, light intensity factor ∈ and α, to represent the light intensity coefficient and influence factor. The remaining energy consumption of mobile terminal equipment was measured respectively, the distance parameter from device to device, the maximum transmission energy consumption, and the correlation coefficient between environmental parameters and energy consumption parameters was analyzed. This paper discusses the impact of different topological structures on the environment, energy saving and emission reduction in the relatively flat terrain area, based on the planning scheme of parking area within the coverage range of base station signal, the transmission capability of vehicles as mobile device nodes within the coverage range of base station signal, and the signal coverage range of base station under different light intensity. As the distance between the base station and the vehicle mobile device node changes, the maximum transmission energy consumption of the mobile device node is obtained. Based on the above factors, the optimal performance optimization parking scheme and the optimal energy consumption optimization transmission scheme are obtained.
