Wave speeds and Green’s tensors for shear wave propagation in incompressible, hyperelastic materials with uniaxial stretch [PDF]
, 2019 Assessing elastic material properties from shear wave propagation following an acoustic radiation force impulse (ARFI) excitation is difficult in anisotropic materials because of the complex relations among the propagation direction, shear wave ...

NISP: Pruning Networks Using Neuron Importance Score Propagation [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 To reduce the significant redundancy in deep Convolutional Neural Networks (CNNs), most existing methods prune neurons by only considering the statistics of an individual layer or two consecutive layers (e.g., prune one layer to minimize the ...

Influences of the state of ionospheric background on ionospheric heating effects
Annals of Geophysics, 2014 According to the well-performed ionospheric heating experiments at Arecibo in the low latitudes as well as at Tromsø in the high latitudes, the large-scale modification effects are simulated under an assumption of equivalent conditions, i.e., with the ...

Galactic positrons and electrons from astrophysical sources and dark matter [PDF]
, 2009 A very interesting puzzle about the origin of electron and positron cosmic rays is deduced from the latests experimental results. We model the propagation of such cosmic rays in terms of a successfully tested two--zone propagation model.

Intelligent Reflecting Surfaces: Physics, Propagation, and Pathloss Modeling [PDF]
IEEE Wireless Communications Letters, 2019 Intelligent reflecting surfaces can improve the communication between a source and a destination. The surface contains metamaterial that is configured to “reflect” the incident wave from the source towards the destination.
