Next‐Generation CAR‐T Cell Therapy: From Modular Design to Clinical Expansion

Exploration, EarlyView.
Over the past decades, chimeric antigen receptor (CAR)‐T cell therapy has evolved from a linear engineering concept into a powerful yet constrained immunotherapy, limited by tumour microenvironment barriers, immune evasion, and manufacturing complexity.

Effects of Lightning Impulses on the Dielectric Properties of HDPE

, 2009
Impulse over-voltages are very common phenomena in electric power systems. Switching impulses are created by switching surges or local faults while lightning impulses are due to lightning strikes to overhead lines.

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Impulse ageing of polymeric materials

, 2011
Impulse over-voltage is a common phenomenon in electric power systems. A switching impulse is created by a switching surge or local fault while a lightning impulse is due to direct lightning strike to high voltage plant such as an overhead line.
