Two new diterpenoid alkaloids from Aconitum legendrei Hand.-Mazz

Ming-Lu Zheng, Feng-Tai Qiu, Qing Tang, Lin Chen et autres

Two new diterpenoid alkaloids, legendredines A (1) and B (2), along with twenty-eight known compounds (3–30), were obtained from the roots of the medicinal plant Aconitum legendrei Hand.-Mazz. Structural characterisation was achieved through Comprehensive spectroscopic analysis, including HR-ESI-MS, IR, and 1D/2D NMR. …

Development of AXUV diagnostic system on the EXL-50U spherical torus

Cong Zhang, Lin Chen, Qifeng Xie, Hui Zhang et autres

Abstract An absolute extreme ultraviolet (AXUV) photodiode array system has been developed and tested on the EXL-50U spherical torus for radiated power measurement. The system utilizes two 16-channel AXUV cameras to provide 32 lines-of-sight (LOS) covering the plasma poloidal cross-section with a …

Flow-OPD: On-Policy Distillation for Flow Matching Models

Zhen Fang, Wenxuan Huang, Yu Zeng, Yiming Zhao et autres

Existing Flow Matching (FM) text-to-image models suffer from two critical bottlenecks under multi-task alignment: the reward sparsity induced by scalar-valued rewards, and the gradient interference arising from jointly optimizing heterogeneous objectives, which together give rise to a 'seesaw effect' of competing metrics …

SCOPE: Structured Decomposition and Conditional Skill Orchestration for Complex Image Generation

Tianfei Ren, Zhipeng Yan, Yiming Zhao, Zhen Fang et autres

While text-to-image models have made strong progress in visual fidelity, faithfully realizing complex visual intents remains challenging because many requirements must be tracked across grounding, generation, and verification. We refer to these requirements as semantic commitments and formalize their lifecycle discontinuity as …

Modular Retrieval-Augmented Generalization for Human Action Recognition

Peng Liao, Shangsong Liang, Lin Chen, Peijia Zheng

Inertial Measurement Unit (IMU)-based Human Activity Recognition (HAR) aims to interpret and classify user behaviors from temporal motion signals. Recently, deep learning frameworks have advanced this task by learning and extracting discriminative spatiotemporal representations, significantly improving recognition performance. However, IMU-based HAR still …
