Real-Time Target Detection in Compressed Domain for Streak Tube LiDAR by Two-Pass Labeling and Sparse Attention

Yunxuan Song, Rongwei Fan, Zhaodong Chen, Deying Chen et autres

Airborne streak tube imaging LiDAR (ASTIL) enables high-frame-rate 3D imaging but suffers from real-time processing bottlenecks due to massive data throughput and costly full decompression. We propose a compressed-domain detection framework that directly processes natively group-sparse (GS) encoded streak images. The pipeline …

Predicting 28-day mortality in artificial liver support-treated HBV–ACLF: development and validation of a novel prognostic model

He Jiang, Deying Chen, Jiong Yu, Guoqi Zhang et autres

This study aimed to develop and internally validate the ANIT (Age, Neutrophil count, INR, Total bilirubin) score for predicting 28-day mortality in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV–ACLF) undergoing artificial liver support systems (ALSS), and to compare its prognostic …

Effects of air discharge modes on airflow organization and temperature uniformity inside automated high-bay cold store

Qunsheng Liu, Haoran Zhang, Deying Chen

To quantitatively evaluate the influence of air discharge configuration on thermal uniformity and energy performance in automated high-bay cold stores, a three-dimensional CFD (Computational Fluid Dynamics) model was developed to systematically compare the airflow distribution and thermal performance under downward and horizontal …

Airborne Streak Tube Imaging LiDAR-Based Effective Reconstruction of Urban Water Areas

Qinfei Zhao, Zhiwei Dong, Rongwei Fan, Yunxuan Song et autres

When LiDAR detects underwater targets, the water severely attenuates the laser beams, making it impossible to extract valid echo information during 3D reconstruction of urban water bodies. This study proposes a Multi-Scale Spectral Adaptive Loss Generative Adversarial Network Based on Morphology-Spatiotemporal Decoupled …

Relative-Height Image Generation from Long-Range Airborne Streak-Tube Imaging LiDAR for Wide-Area Building- Structure Mapping

Chaowei Dong, Zhaodong Chen, Rongwei Fan, Zhiwei Dong et autres

Wide-area building-structure mapping from long-range airborne LiDAR requires image products that can represent building footprints, roof-height variations, and structural discontinuities with low computational latency. Airborne streak-tube imaging LiDAR (ASTIL) records a spatial-temporal echo image for each laser pulse, where the detector row …

Lightweight Raw Echo Image Preprocessing for Long-Range Airborne Streak Tube Imaging LiDAR Using Adaptive Frequency-Domain Noise Suppression

Chaowei Dong, Rongwei Fan, Zhaodong Chen, Zhiwei Dong et autres

Long-range airborne streak tube imaging lidar (ASTIL) raw echo images are degraded by atmospheric speckle, detector noise, and weak-return fluctuations, which can bias centroid localization before range calculation. This study presents a lightweight preprocessing method combining row–column geometry-aware echo region pre-classification with …

Characterization of multi-stage metabolic alterations in hepatitis B virus-related acute-on-chronic liver failure using high-coverage metabolomics

Zhehua Zhang, He Jiang, Guoqi Zhang, Deying Chen et autres

INTRODUCTION: Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a serious condition characterized by acute liver decompensation and multiple organ failure, which leads to high short-term mortality rates. OBJECTIVES: This study aims to understand the metabolic changes across different stages-normal, chronic hepatitis …

Research on discrete noise suppression method for single-photon LiDAR based on voxel filtering and octree structure

Zhaodong Chen, Chengdong Zhang, Zhiwei Dong, Rongwei Fan et autres

Single-Photon LiDAR (SPL) faces various noise interference in long-range detection and complex environmental applications, especially in low photon return conditions. The noise significantly impacts LiDAR data processing, leading to signal misinterpretation and degradation in point cloud quality, thereby affecting reconstruction accuracy. This …

Laser long-range large-size line spot homogenization based on microlens arrays

Mengfei Wang, Rongwei Fan, Zhaodong Chen, Zhiwei Dong et autres

Streak tube lidar usually needs to shape the outgoing light into a line beam, which is projected onto the surface of the target at a long distance, and after reflected by the target, the reflected light carries the target's intensity and distance …

Chronic Periodontitis and Non-Alcoholic Fatty Liver Disease: Recent Advances in Mechanisms of Association

Jieying Zhu, Deying Chen

Background: Chronic periodontitis (CP) and non-alcoholic fatty liver disease (NAFLD) are increasingly prevalent worldwide. Although mechanisms remain incompletely defined, recent studies suggest a close association between these two diseases. This review systematically outlines potential links between periodontitis and NAFLD, emphasizing their pathological …
