Vibrational excitation effects on thermodynamic fluctuations in shock–vortical turbulence interaction

Fangcheng Shi, Hongpeng Liu, Yazhong Jiang, Tiantian Wang

The effect of vibrational excitation on thermodynamic fluctuations in shock-vortical turbulence interaction (SVTI) is investigated using direct numerical simulations and extended linear interaction analysis (LIA). Comparing thermally perfect gas and calorically perfect gas models at shock Mach numbers (Ms) of 4.0 and …

Integrating frequency domain reconstruction with time-adaptive fusion network for rolling bearing remaining useful life prediction

Fangcheng Shi, Fang Yi, Jingsong Xie, Tiantian Wang et autres

Abstract Rolling bearing remaining useful life (RUL) prediction plays a critical role in equipment health management. However, noise in practical engineering applications can submerge early weak degradation features, making it difficult to capture early degradation patterns. This constrains the application of prediction …

QP-OneModel: A Unified Generative LLM for Multi-Task Query Understanding in Xiaohongshu Search

Jianzhao Huang, Xiaorui Huang, Fei Zhao, Yunpeng Liu et autres

Query Processing (QP) bridges user intent and content supply in large-scale Social Network Service (SNS) search engines. Traditional QP systems rely on pipelines of isolated discriminative models (e.g., BERT), suffering from limited semantic understanding and high maintenance overhead. While Large Language Models …

Decouple Searching from Training: Scaling Data Mixing via Model Merging for Large Language Model Pre-training

Shengrui Li, Fei Zhao, Kaiyan Zhao, Jiaqi Ye et autres

Determining an effective data mixture is a key factor in Large Language Model (LLM) pre-training, where models must balance general competence with proficiency on hard tasks such as math and code. However, identifying an optimal mixture remains an open challenge, as existing …
