A novel dual-permanent-magnet-excited machine for low-speed large-torque applications

L Jian, Y Shi, C Liu, G Xu, Y Gong… - IEEE transactions on …, 2013 - ieeexplore.ieee.org
This paper proposes a novel dual-permanent-magnet-excited (DPME) machine, in which
two sets of permanent magnets (PMs) are employed, one on stator and the other on rotor. Bi-…

All tokens matter: Token labeling for training better vision transformers

…, Q Hou, L Yuan, D Zhou, Y Shi… - Advances in neural …, 2021 - proceedings.neurips.cc
In this paper, we present token labeling---a new training objective for training high-performance
vision transformers (ViTs). Different from the standard training objective of ViTs that …

Leveraging instance-, image-and dataset-level information for weakly supervised instance segmentation

Y Liu, YH Wu, P Wen, Y Shi, Y Qiu… - IEEE Transactions on …, 2020 - ieeexplore.ieee.org
Weakly supervised semantic instance segmentation with only image-level supervision,
instead of relying on expensive pixel-wise masks or bounding box annotations, is an important …

Osteoinduction of hydroxyapatite/β-tricalcium phosphate bioceramics in mice with a fractured fibula

L Cheng, F Ye, R Yang, X Lu, Y Shi, L Li, H Fan, H Bu - Acta biomaterialia, 2010 - Elsevier
Many studies have shown that calcium phosphate ceramics can induce bone formation in
non-osseous sites without the application of any osteoinductive biomolecules, but the …

Learning with fantasy: Semantic-aware virtual contrastive constraint for few-shot class-incremental learning

Z Song, Y Zhao, Y Shi, P Peng… - Proceedings of the …, 2023 - openaccess.thecvf.com
Few-shot class-incremental learning (FSCIL) aims at learning to classify new classes
continually from limited samples without forgetting the old classes. The mainstream framework …

[HTML][HTML] Exosomes derived from human umbilical cord mesenchymal stem cells ameliorate IL-6-induced acute liver injury through miR-455-3p

…, X Cao, M Chen, B Zhang, Y Zhou, R Yao, Y Shi… - Stem cell research & …, 2020 - Springer
