A Dynamic Contrast‐Enhanced MRI‐Based Vision Transformer Model for Distinguishing HER2‐Zero, ‐Low, and ‐Positive Expression in Breast Cancer and Exploring Model Interpretability

open access: yesAdvanced Science, EarlyView.
This study develops a Vision Transformer‐based DCE‐MRI model for the non‐invasive classification of HER2 expression in breast cancer, demonstrating robust performance across multicenter cohorts. By integrating transcriptomic analysis, the model reveals immune‐related pathway differences among distinct HER2 expression levels.

Delayed Transplantation of Neural Stem Cells Improves Initial Graft Survival after Stroke

open access: yesAdvanced Science, EarlyView.
Delayed transplantation of human iPSC‐derived neural progenitor cells (NPCs) enhances graft survival, proliferation, and axonal sprouting after stroke. Using bioluminescence imaging and histology in a mouse model of stroke, it is shown that NPC delivery at 7 days post‐stroke is more effective than acute transplantation, highlighting the importance of ...

Resource allocation scheme in two-way multi-relay OFDM system

open access: yesTongxin xuebao, 2017
A joint optimization scheme for power allocation and subcarrier pairing under high SNR in two-way multi-relay OFDM system was proposed.Unlike those schemes in which relays use subcarriers separately,all the relays were allowed to forward signal on each ...
