Abstract: We propose seismic elastic full-waveform inversion (EFWI) using both the multiparametric approximate Hessian and the discrete cosine transform (DCT). EFWI is a promising technology for ...

Learn how to crochet an elastic stitch using the tubular herringbone technique. This step-by-step tutorial shows how to create a stretchy, clean, and professional-looking crochet stitch perfect for ...

Abstract: Multicomponent elastic Gaussian-beam migration (EGBM) is relatively accurate, efficient, and flexible. However, a large amount of land seismic data is recorded by single-component geophones, ...

The clinical performance of dental implants is strongly defined by biomechanical principles. The aim of this study was to quantify the Vicker's hardness (VHN) and elastic modulus (E) surround bone to ...

A new shape shifting material can twist, bend, and snap into more than a dozen 3D forms without motors or wires, a breakthrough in "snapping morphogenesis" by NC State researchers led by Jie Yin. GOP ...
