Full waveform inversion method of P-wave and S-wave velocity based on wave equation traveltime under shear wave source

Frontiers in Earth Science
Elastic full-waveform inversion serves as a fundamental technique for recovering subsurface elastic parameters. However, its application is hindered by mode coupling between P- and S-waves, multi-parameter crosstalk, and a strong dependence on the ...

Systemic Nanomechanical Single‐Cell Profiling Reveals Mechanophenotype Transitions Under Therapeutic Perturbation

Advanced Science, EarlyView.
Single‐cell mechanomics demonstrates that pharmacological perturbation changes cytoskeletal and cortical structure, suppressing cancer cell invasiveness. By integrating atomic force microscopy (AFM)‐based cortical measurements with stimulated emission depletion (STED)‐resolved adhesion and cytoskeletal organization, this approach identifies nanoscale ...

A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

Advanced Science, EarlyView.
This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

Comparative analysis of Pn full-waveform inversion and travel-time tomography in imaging upper mantle azimuthal anisotropy

Frontiers in Earth Science
Conventional Pn-wave imaging techniques, typically based on the ray theory, rely on Pn travel times to resolve the 2-D velocity and azimuthal anisotropy structures of the uppermost mantle. However, these approaches neglect the finite-frequency effects of
