AutoPSO: A Meta-framework for Automated Particle Swarm Optimization

Xinmeng Yu, Jiaxin Gao, Jianguo Zhang, Dongmei Jiang et autres

Particle swarm optimization (PSO) is a widely used metaheuristic, prized for its simplicity and small parameter set. Although decades of research have produced numerous PSO variants that improve performance by modifying key components (e.g., parameter schedules, swarm topologies, or updating rules), two …

SNOC: Subtle Nested Objective Configuration for Joint Ultra-Low-Light Enhancement and Super-Resolution

Jiaxin Gao, Yaohua Liu, Danchen Cui, Zhihui Zhao

Ultra-low-light image restoration remains challenging in part because static optimization objectives are often brittle across the diverse degradation patterns induced by extreme darkness. Existing joint enhancement and super-resolution paradigms predominantly rely on manually specified objective trade-offs, leading to scene-dependent failures such as …

Effects of graded talar external rotation on distal tibial articular surface stress and contact pressure: a finite element study

Xinya Lan, JiYuan Mo, Jiaxin Gao, Yaping Li et autres

Background: Abnormal talar biomechanics alter tibiotalar local mechanics and are implicated in several ankle-foot disorders. However, the relationship between graded talar external-rotation moments and local articular changes under controlled loading remains unclear. This study investigated the variation pattern and spatial migration of …

Strangeness production in $p$Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV in the PACIAE model

Qiang Wang, An-Ke Lei, Zhi-Lei She, Jiaxin Gao et autres

We present a study of the single- and multi-strange particle productions in $p$Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV using the PACIAE 4.0 model. The effects of the color reconnection (CR), rope hadronization (RH) as well as the partonic and hadronic rescatterings …

Lethe: Purifying Backdoored Large Language Models with Knowledge Dilution

Chen Chen, Y. J. Sun, Jiaxin Gao, Qian Wang et autres

Large language models (LLMs) have seen significant advancements, achieving superior performance in various Natural Language Processing (NLP) tasks. However, they remain vulnerable to backdoor attacks, where models behave normally for standard queries but generate harmful responses or unintended output when specific triggers …

GST-enhanced fiber SPR curvature sensor

Xuhao Ji, Zhuo Ren, N. Yu, Jianan Liu et autres

This paper proposes a high-sensitivity surface plasmon resonance (SPR) curvature sensor based on hard polymer-clad fiber (HPCF). The sensor utilizes an HPCF coated with gold and Ge2Sb2Te5 (GST), with a layer of polydimethylsiloxane (PDMS) as the sensing medium for curvature measurement. GST …
