Preparation of Multi-Crosslinked Self-Foaming Water-Swellable Rubber

|
By Yanru Hou, Wenbo Li, Xin Ding
| Wiley Online Library Verified
1 Introduction Water-swellable rubber (WSR) is a novel functional elastomer with elastic sealing and swelling properties. Upon contacting water, it undergoes swelling and can achieve excellent sealing performance when employed as waterproof sealing material. Therefore, it shows extensive applications in joint sealing, gap sealing, and waterproofing of civil engineering, as well as maintaining airtightness preservation of mechanical equipment [1-4].

Zetta ζ: An Efficient Closed-Loop Embodied Harness for Self-Evolving Physical Intelligence

|
By Xin Ding, Mingzhe Huang, Zixuan Wang
| huggingface.co
Abstract Zetta is a closed-loop embodied harness that evolves runtime critics and recovery skills online to govern physical execution at action frequency, achieving high success on robot benchmarks with faster inference and scaling self-exploration. Embodied agents are increasingly used to close the gap left by end-to-end policy models.

By Yule Xie, Jiaxin Ding, Xin Ding
| arXiv
Reinforcement learning has become a central paradigm for improving the reasoning capabilities of large language models. Existing methods generally aim to reduce the failure probabilities induced across problems. In this paper, we introduce a moment-based perspective on policy optimization for LLM reasoning by treating the failure probability of a randomly sampled problem as a random variable and characterizing optimization objectives through its moments.
