Edge-Cloud Collaborative RAG with Multi-State Semantic Caching

Kang Liu, Guangping Xu, Yaru Fu, Mingyuan Ding et autres

Enterprise applications are increasingly adopting collaborative Retrieval Augmented Generation (RAG) frameworks that synergize Small Language Models (SLMs) at the network edge with Large Language Models (LLMs) in the cloud for joint reasoning. However, this paradigm is bottlenecked by the capacity asymmetry between …

ZSWP: Rollback-Free Spherical ε-Join for Scalable Astronomical Cross-Matching on Heterogeneous Supercomputer Architectures

Yuhao Yuan, Ce Yu, Jingwen Xing, Hao Fu et autres

Spherical ϵ -join tasks, including astronomical cross-matching, satellite conjunction assessment, and global geospatial fusion, require exact pairwise distance checks on the unit sphere at billion-object scales. While modern heterogeneous supercomputers offer substantial compute throughput, efficient data organization and coordination across deep memory …

Comment on egusphere-2026-3196

Yiqi Chen, Le Cao, Xiaochun Zhu, Yan Xia et autres

Abstract. Springtime tropopause folds facilitate stratosphere–troposphere exchange and may influence Arctic tropospheric composition, yet their long-term variability and dynamical background over the Arctic remain insufficiently characterized. Here, we use ERA5 reanalysis data and a three-dimensional labeling algorithm to identify tropopause folds over …

Three‐Dimensional Distributions and Seasonality of Interannual Trends in the Stratospheric Contribution to Tropospheric Ozone Over China: A 37‐Year Modeling Study

Yuxiang Jin, Xuewei Hou, Tianliang Zhao, Yuehan Luo et autres

Abstract Stratospheric ozone (O 3 S) is a key natural source of tropospheric ozone, yet its vertical structure, seasonality, and interannual changes remain poorly characterized over China and surrounding regions. Leveraging 37 years of CESM2 simulations, which are rigorously evaluated against multi‐model …

Computation-Assisted Development of a Rhodamine-Based off-to-on Fluorescent Nanoprobe for Precise Uranyl Ion Detection in Diverse Real-Life Scenarios

Xiaoxue Sun, Zhiwei Li, T. Liang, Yang Li et autres

Uranyl ion (UO22+), a highly toxic and radioactive heavy metal species, poses severe threats to human health and environmental safety. Therefore, developing easy-to-operate, rapid, and efficient strategies for UO22+ detection is of critical importance. Herein, leveraging the fluorescence "off-to-on" transition triggered by …

Spatiotemporal Distribution of Tropopause Folds over the Arctic during Spring Season: A 24-Year Analysis (2000–2023)

Yiqi Chen, Le Cao, Xiaochun Zhu, Yan Xia et autres

Abstract. Springtime tropopause folds facilitate stratosphere–troposphere exchange and may influence Arctic tropospheric composition, yet their long-term variability and dynamical background over the Arctic remain insufficiently characterized. Here, we use ERA5 reanalysis data and a three-dimensional labeling algorithm to identify tropopause folds over …

2H‐Phase Molybdenum Diselenide/Hollow Carbon Sphere‐Based Separator With “One‐Stone‐Two‐Birds” Effect Boosting High‐Performance Lithium‐Sulfur Batteries

Zhijiang Su, Chunwei Dong, Zhihua Han, Tong Yang et autres

ABSTRACT Lithium‐sulfur batteries (LSBs) offer advantages such as high energy density, cost‐effectiveness, and abundant sulfur resources and therefore are regarded as ideal large‐scale energy storage systems. However, due to the shuttle effect caused by the dissolution of soluble lithium polysulfides (LiPSs) into …

Does Higher Vertical Resolution in Meteorological Data Guarantee the Identification of More Tropopause Folds Using the 3D Labeling Algorithm?

Junfeng Miao, Le Cao, Liqiang Xu, Tianqi Zhang et autres

Abstract Stratosphere-to-troposphere transport (STT), a major source of tropospheric ozone, is largely driven by tropopause folds. The accurate identification of these folds is therefore crucial for atmospheric chemistry and air quality studies. In this study, we compared tropopause folds identified from ERA5 …

Free-surface deformation and air entrainment in turbulent flow past a rotating cylinder beneath a water–air interface

Jianfeng Lin, Zenghui Zhu, Xuxiang Cao, L. Z. Cai et autres

ABSTRACT The flow past a fully submerged rotating cylinder beneath a free surface involves complex multiphase interactions, including free-surface deformation, air entrainment, and wave breaking. Using large-eddy simulation coupled with the volume-of-fluid method, we investigate these phenomena at R e = 6 …
