Governed Persistent Memory: Source-Bound State Semantics and Fail-Closed Release for Long-Horizon Agents

Guodong Xu

Long-term agent memory is usually treated as select--store--retrieve, but retrieval does not decide whether contradictory, superseded, retracted, deleted, or stale records may support an outgoing claim. We introduce Governed Persistent Memory (GPM), an auditable bitemporal state-transition model with source-bound admission, derived lifecycle …

A novel fast-convergence evolutionary game model for mobile terminal’s AP selection in substation WAPI networks

Baozhen Qi, Dongsheng Jing, D Q Wang, Guodong Xu et autres

For the substation WAPI networks, there are a large number of mobile terminals, which often roam to some different access points (APs). Faced with these APs, each terminal has to solve such a problem: how to select the optimal AP for the …

Recycling Waste Rubber Into Single‐Walled Carbon Nanotubes: Narrow Chirality Distribution and Hydrogen Byproduct

Zhaoyang Han, Qianru Wu, Xuan Lv, Fedor M. Maksimov et autres

ABSTRACT Waste rubber products pose a significant threat to the Earth's ecological environment due to their non‐biodegradability and long‐term persistence. In this study, we present a method for converting various rubber products into single‐walled carbon nanotubes (SWNTs) and hydrogen (H 2 ) …

Initial experience of a simplified modified Politano-Leadbetter technique for pneumovesicoscopic ureteral reimplantation in children

Haihua Xu, Qingya Meng, Yi Zhang, Guodong Xu et autres

Background: Pneumovesicoscopic ureteral reimplantation (PVUR) has gained popularity due to its minimally invasive characteristics. Most reported PVUR procedures, however, have employed the Cohen technique. The Politano-Leadbetter (PL) technique offers distinct advantages, including the creation of a longer submucosal? Tunnel and preservation of …
