Continuum Mechanics for Quantum Many-Body Systems: The Linear Response Regime [PDF]

, 2010
We derive a closed equation of motion for the current density of an inhomogeneous quantum many-body system under the assumption that the time-dependent wave function can be described as a geometric deformation of the ground-state wave function.

Impulsive Signals Produced by Earthquakes in Italy and Their Potential Relation with Site Effects and Structural Damage

Geosciences, 2021
Near fault seismic records may contain impulsive motions in velocity-time history. The seismic records can be identified as impulsive and non-impulsive depending on the features that their waveforms have.

Quantum squeezing of motion in a mechanical resonator [PDF]

, 2015
As a result of the quantum, wave-like nature of the physical world, a harmonic oscillator can never be completely at rest. Even in the quantum ground state, its position will always have fluctuations, called the zero-point motion. Although the zero-point

Automated quantification and evaluation of motion artifact on coronary CT angiography images [PDF]

, 2018
Purpose This study developed and validated a Motion Artifact Quantification algorithm to automatically quantify the severity of motion artifacts on coronary computed tomography angiography (CCTA) images. The algorithm was then used to develop a Motion IQ

Recorded displacements in a landslide slope due to regional and teleseismic earthquakes [PDF]

, 2015
Regional and teleseismic earthquakes can induce displacements along joints in a landslideinvolved rocky slope in Central Italy. The rarity of these effects is due to specific physical properties of the seismic signals associated with: (i) the energy ...

Nonlinear Dynamic Analysis of Tall Bridge Piers Under Multidimensional Pulse Earthquakes Considering Varying Damping Ratios

Applied Sciences
The dynamic response of tall bridge piers with varying damping ratios under three-dimensional pulse ground motion remains insufficiently understood. To control the pulse characteristic parameters accurately and eliminate interference from actual seismic ...

Investigating the effectiveness of rupture directivity during the August 24, 2016 Mw 6.0 central Italy earthquake

Annals of Geophysics, 2016
In this study we investigate directivity effects associated to the Mw6.0 Amatrice earthquake taking into account the source rupture heterogeneities. We use the directivity predictor proposed by Spudich et al.

Complex numerical modeling of dynamics and crashes of wing-in-ground vehicles [PDF]

, 1993
The Wing-In-Ground craft (WIG), a vehicle flying in the ground effect, is a promising transportation means of the near future. This paper describes mathematical modeling of WIG motion in all regimes, such as planing, take-off, transition to flight ...
