Estimation of Joint Kinematics and Fingertip Forces using Motoneuron Firing Activities: A Preliminary Report

2021 10TH INTERNATIONAL IEEE/EMBS CONFERENCE ON NEURAL ENGINEERING (NER), pp. 1035–1038.

By: F. Xu*, Y. Zheng* & X. Hu*

TL;DR: A novel decoding method that used finger-specific motoneuron firing frequency to estimate joint kinematics and fingertip forces and showed that the MU firing based approach led to smaller prediction errors for both joint angles and forces compared with the conventional EMG amplitude based method.

Large anelasticity and associated energy dissipation in single-crystalline nanowires

Nature Nanotechnology, 10(8), 687–691.

By: G. Cheng n, C. Miao *, Q. Qin n, J. Li n, F. Xu n, H. Haftbaradaran *, E. Dickey n , H. Gao *, Y. Zhu n 

Contributors: G. Cheng n, C. Miao *, Q. Qin n, J. Li n, F. Xu n, H. Haftbaradaran *, E. Dickey n , H. Gao *, Y. Zhu n 

TL;DR: It is shown that single-crystalline ZnO and p-doped Si nanowires can exhibit anelastic behaviour that is up to four orders of magnitude larger than the largest anelastically observed in bulk materials, with a timescale on the order of minutes, suggesting that crystalline Nanowires with point defects are promising materials for energy damping applications.
