A Video Code Based on Distribution Compressive Sensing
Procedia Engineering, 2012 AbstractCompressed sensing (CS) is a new technique for simultaneous data sampling and compression. In this paper, we propose a new video coding algorithm based on Distributed Compressive Sampling(DCS) principles, where almost all computation burdens can be shifted to the decoder, resulting in a very lowcomplexity encoder.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...
