Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

BJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Integrating Machine Learning With Constant‐Potential Simulation to Unravel Charge‐Transfer Mechanisms in Electrochemical Nitrogen Fixation

Advanced Science, EarlyView.
Integrating interpretable machine learning with the fixed‐potential method reveals a novel mechanism: the catalytic activity of the electrochemical nitrogen reduction reaction is governed by partial charge transfer, induced by variations in the intermediate potential of zero charge under constant potential.
