Functional Connectivity Linked to Cognitive Recovery After Minor Stroke
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Three New Distance-regular Graphs
European Journal of Combinatorics, 1993 We describe three new diameter 4 distance-regular triple covers of strongly regular graphs. The first two such covers are distance- transitive, with intersection arrays \{416,315,64,1;1,32,315,416\} and \{56,45,16,1;1,8,45,56\}. The third has intersection array \{32,27,8,1;1,4,27,32\}, but is not distance-transitive.

On Subgraphs in Distance-Regular Graphs [PDF]
Journal of Algebraic Combinatorics, 1992 A graph is distance-regular when it is simple and for any two vertices at distance \(j\), the numbers of vertices adjacent to one and at distance \(j- 1\) (resp. \(j\) and \(j+1)\) of the other are constant (depending on \(j\) only). First some necessary conditions are derived for distance- regularity of the subgraph of the geodesics joining two ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...
