GACNet: Interactive Prediction of Surrounding Vehicles Behavior under High Collision Risk

open access: yesAdvanced Intelligent Systems, EarlyView.
This study designs a dual‐stage prediction framework and introduces a conflict analysis module. This module refines the initially predicted future trajectories and performs collision detection and behavior analysis on the refined trajectories, thereby learning the true interactive behaviors of multiple agents in high‐collision‐risk scenarios.

The Age–Velocity Dispersion Relations of the Galactic Disk as Revealed by the LAMOST-Gaia Red Clump Stars

open access: yesThe Astrophysical Journal
Using nearly 230,000 red clump stars selected from LAMOST and Gaia, we conduct a comprehensive analysis of the stellar age–velocity dispersion relations (AVRs) for various disk populations, within 5.0 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc.

Autogenous self‐healing of concrete: Experimental design and test methodsA review

open access: yesEngineering Reports, Volume 5, Issue 1, January 2023., 2023
Concrete exhibits an intrinsic ability to heal cracks, defined as “autogenous self‐healing.” However, despite code restrictions, autogenous self‐healing of concrete shows limited effectiveness in practice. This indicates the need for further research to provide engineers with reliable design rules.

Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations

open access: yesAnnalen der Physik, EarlyView.
A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

open access: yesEngineering Reports, Volume 5, Issue 1, January 2023., 2023
Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

Bifunctional Mesoporous MO x (M = Cr, Fe, Co, Ni, Ce) Oxygen Electrocatalysts for Platinum Group Metal‐Free Oxygen Pumps

open access: yesEnergy Technology, Volume 10, Issue 12, December 2022., 2022
The family of high‐quality crystalline mesoporous MOx synthesized via soft‐templated hydrothermal synthesis is investigated in oxygen reduction reaction and oxygen evolution reaction electrocatalysis. Using developed NiO, the symmetrical platinum group metal‐free oxygen pump is elaborated for the first time.
