Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix
Advanced Functional Materials, EarlyView.Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Study on the coupling vibration characteristics at the junction of metro carriages
Mechanical Engineering Journal, 2021 Aiming at the problem of dislocation at the junction of metro carriages, a three DOF (degree of freedom) coupled vibration model of the junction of metro carriages was established. Then, the kinetic equation of vibration model was established by Lagrange

Scaling of Traction Forces with Size of Cohesive Cell Colonies
, 2012 To understand how the mechanical properties of tissues emerge from interactions of multiple cells, we measure traction stresses of cohesive colonies of 1-27 cells adherent to soft substrates.

Cooperative cell motility during tandem locomotion of amoeboid cells. [PDF]
, 2016 Streams of migratory cells are initiated by the formation of tandem pairs of cells connected head to tail to which other cells subsequently adhere. The mechanisms regulating the transition from single to streaming cell migration remain elusive, although ...

Traction forces during collective cell motion [PDF]
HFSP Journal, 2009 Collective motion of cell cultures is a process of great interest, as it occurs during morphogenesis, wound healing, and tumor metastasis. During these processes cell cultures move due to the traction forces induced by the individual cells on the surrounding matrix. A recent study [Trepat, et al. (2009). Nat. Phys.

Traction forces of cancer cells [PDF]
Computer Methods in Biomechanics and Biomedical Engineering, 2011 Cell motility of cancer cells is a fundamental problem, and requires precise correlation between cell adhesive and rheological properties. The migration of cancer cells is studied in two dimensions, as cells are seeded onto functionnalized polyacrylamide gels.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control
Advanced Functional Materials, EarlyView.A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...
