Mar 01 2011 · Dust in the monsoon flow was found to be mainly mobilized by the passage of a density current related to a mesoscale convective system and strong nearsurface winds and turbulence Knippertz et al 2009 analysed the synoptic conditions for dust emission and transport in the northern Sahara during the Saharan Mineral Dust Experiment SAMUM in
Ultrasound can be used to wirelessly power and communicate with mmscale devices implanted in the body Seo Neely et al demonstrate wireless recordings from nerve ENG and muscle EMG in anesthetized rats using neural dusta batteryless ultrasonic backscattering system
The density and velocity fields within 70 h−1 Mpc exhibit similarities qualitatively consistent with gravitational instability theory and a linear biasing relation between clusters and mass
