A seismic attenuation estimation approach is proposed based on multivariate variational mode decomposition (MVMD). MVMD, as a multivariable or multichannel signal processing tool, can extract several ...

Physical activity attenuates survival disparity between patients with stage III colon cancer and matched population controls.

Noise margin, also known as signal-to-noise ratio (SNR), is the difference between the signal strength and the background noise on your DSL line. The higher the noise margin, the better the ...

This paper presents a new control structure for ball screw drives (BSDs), which achieves position tracking through an outer loop, and active vibration damping for dynamic stiffness enhancement through ...

It is currently believed that inflammation plays a central role in the pathophysiology of atherosclerosis. Oxidative stress and redox-sensitive transcription factors are implicated in the process.

Engineer Cris Alexander reviewed the NRSC's study on AM noise. He says it reveals the need for higher AM signal strengths to ...

MLAA is a joint estimation algorithm that simultaneously estimates the emission as well as attenuation values using an intensity prior that favors mu-values of air and tissue. In gated MR/PET cardiac ...
