Ab Initio Benchmarking on Unsupported and Coronene‐Supported Silver Atomic Clusters: Interplay Between Jahn–Teller Distortions and Fluxionality

Small Structures, EarlyView.
The article presents a benchmark study using state‐of‐the‐art high‐level ab initio methodologies to predict infrared and Raman frequencies of subnanometric metal clusters. The importance of characterizing conical intersections in their potential energy landscapes is also highlighted, with the associated (Pseudo‐)Jahn–Teller distortions of cluster ...

Cement Lines are Stiffer and Harder than Bone but Exhibit Different Mineral–Mechanics Relationships due to Thicker and Shorter Mineral Particles

Small Structures, EarlyView.
Bone's complex hierarchical structure contains many internal interfaces, including the cement line (CL) around osteons. This article shows that the CL is stiffer and harder than surrounding bone but has different mineral–mechanics relationships. These findings challenge the view of the CL as a soft, protective interface and provide insights for ...

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

Coevolutionary Neural Dynamics With Learnable Parameters for Nonconvex Optimisation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Nonconvex optimisation plays a crucial role in science and industry. However, existing methods often encounter local optima or provide inferior solutions when solving nonconvex optimisation problems, lacking robustness in noise scenarios. To address these limitations, we aim to develop a robust, efficient and globally convergent solver for ...

Distributed Formation Control for Heterogeneous Robot Systems Based on Competitive Mechanism

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper presents an adaptive formation control method for a heterogeneous robot swarm, utilising a multilevel formation task tree to model various types of formation tasks and a single‐state distributed k‐winner‐take‐all (S‐DKWTA) algorithm to address the MRTA problem.
