Particle acceleration in thick parallel shocks with high compression ratio [PDF]
Astronomy & Astrophysics, 2005 We report studies on first-order Fermi acceleration in parallel modified shock waves with a large scattering center compression ratio expected from turbulence transmission models. Using a Monte Carlo technique we have modeled particle acceleration in shocks with a velocity ranging from nonrelativistic to ultrarelativistic and a thickness extending from

Scalable Coding for High-Resolution, High-Compression Ratio Snapshot Compressive Video
IEEE Transactions on Image ProcessingHigh-speed cameras are crucial for capturing fast events beyond human perception, although challenges in terms of storage, bandwidth, and cost hinder their widespread use. As an alternative, snapshot compressive video can overcome these challenges by exploiting the principles of compressed sensing to capture compressive projections of dynamic scenes ...
