Deconstruction and reconstruction of image-degrading effects in the human abdomen using Fullwave: phase aberration, multiple reverberation, and trailing reverberation
Danai Eleni Soulioti, Francisco Santibanez, Gianmarco Pinton
Ultrasound image degradation in the human body is complex and occurs due to the distortion of the wave as it propagates to and from the target. Here, we establish a simulation base…
Quantitative sub-resolution blood velocity estimation using ultrasound localization microscopy ex-vivo and in-vivo
David Espindola, Ryan M. DeRuiter, Francisco Santibanez +2
Super-resolution ultrasound imaging relies on the sub-wavelength localization of microbubble contrast agents. By tracking individual microbubbles, the velocity and flow within micr…
Effect of an interstitial fluid on the dynamics of three-dimensional granular media
Rene Zuniga, Stephane Job, Francisco Santibanez
The propagation of mechanical energy in granular materials has been intensively studied in recent years given the wide range of fields that have processes related to this phenomena…
Mechanical impulse propagation in a packing of 3D spheres confined at constant pressure
Francisco Santibanez, Rene Zuñiga, Francisco Melo
Mechanical impulse propagation in granular media depends strongly on the imposed confinement conditions. In this work, the propagation of sound in a granular packing contained by f…
Stress-dependent normal mode frequencies from the effective mass of granular matter
Yanqing Hu, David L. Johnson, John J. Valenza +2
A zero-temperature critical point has been invoked to control the anomalous behavior of granular matter as it approaches jamming or mechanical arrest. Criticality manifests itself…
Experimental evidence of solitary wave interaction in Hertzian chains
F. Santibanez, R. Munoz, A. Caussarieu +2
We study experimentally the interaction between two solitary waves that approach one to another in a linear chain of spheres interacting via the Hertz potential. When these counter…
Wave localization in strongly nonlinear Hertzian chains with mass defect
S. Job, F. Santibanez, F. Tapia +1
We investigate the dynamical response of a mass defect in a one-dimensional non-loaded horizontal chain of identical spheres which interact via the nonlinear Hertz potential. Our e…
Experimental evidence of shock mitigation in a Hertzian tapered chain
Francisco Melo, Stephane Job, Francisco Santibanez +1
We present an experimental study of the mechanical impulse propagation through a horizontal alignment of elastic spheres of progressively decreasing diameter , namely a tapere…
