Multi-Sensor and Decision-Level Fusion-Based Structural Damage Detection Using a One-Dimensional Convolutional Neural Network.
Teng S, Chen G, Liu Z, Cheng L, Sun X. Teng S, et al. Sensors (Basel). 2021 Jun 8;21(12):3950. doi: 10.3390/s21123950. Sensors (Basel). 2021. PMID: 34201143 Free PMC article.
As structural damage usually induces changes in the dynamic responses of a structure, a CNN can effectively extract structural damage information from the vibration signals and classify them into the corresponding damage categories. However, it is difficult to build a larg …

Direct Dynamics Trajectories Demonstrate Dynamic Matching and Nonstatistical Radical Pair Intermediates during Fe-Oxo-Mediated C-H Functionalization Reactions.
Joy J, Ess DH. Joy J, et al. J Am Chem Soc. 2023 Apr 5;145(13):7628-7637. doi: 10.1021/jacs.3c01196. Epub 2023 Mar 23. J Am Chem Soc. 2023. PMID: 36952628
Trajectories revealed that the radical pair intermediate can be a nonstatistical type intermediate without complete internal vibrational redistribution and post-HAT selectivity is generally determined by dynamic effects. Fast rebound trajectories occur through dynamic matc …
