Matrix Stiffness Directs Stemness Signatures in Breast Cancer
Advanced Healthcare Materials, EarlyView.We built lab‐grown breast cancer models to study how the stiffness of the tumor's surroundings influences cancer behavior. Softer environments encouraged more stem‐like, drug‐resistant cells, while stiffer ones kept cells more differentiated. These findings show that tissue mechanics drive cancer diversity and drug resistance, offering new insights for

An instantaneous frequency-based computation of transparent motion [PDF]
We extend the principle of phase-based techniques for measuring optical flow and binocular disparity to multiple motion estimation. Using quadrature filter pairs, we estimate phase gradients (instantaneous frequency) from independent bandpass channels ...
