On the origin of the gravitational quantization: The Titius--Bode Law

, 2005
Action at distance in Newtonian physics is replaced by finite propagation speeds in classical post--Newtonian physics. As a result, the differential equations of motion in Newtonian physics are replaced by functional differential equations, where the ...

Analytical solution of the dynamical spherical MIT bag [PDF]

, 2001
We prove that when the bag surface is allowed to move radially, the equations of motion derived from the MIT bag Lagrangian with massless quarks and a spherical boundary admit only one solution, which corresponds to a bag expanding at the speed of light.

Unified linear response theory of quantum electronic circuits

npj Quantum Information
Modeling the electrical response of multi-level quantum systems at finite frequency has been typically performed in the context of two incomplete paradigms: (i) input-output theory, which is valid at any frequency but neglects dynamic losses, and (ii ...

Covariant Treatment of Neutrino Spin (Flavour) Conversion in Matter under the Influence of Electromagnetic Fields

, 2001
Within the recently proposed Lorentz invariant formalism for description of neutrino spin evolution in presence of an arbitrary electromagnetic fields effects of matter motion and polarization are considered.Comment: Extended version of contribution to ...

Motion Artifact Reduction in Quantitative Susceptibility Mapping using Deep Neural Network [PDF]

arXiv, 2021
An approach to reduce motion artifacts in Quantitative Susceptibility Mapping using deep learning is proposed. We use an affine motion model with randomly created motion profiles to simulate motion-corrupted QSM images. The simulated QSM image is paired with its motion-free reference to train a neural network using supervised learning.

Herminio: sculpture, physics and motion

Sculpture Journal, 2013
This article looks to make a philosophical reading of a number of sculptures by Herminio Alvarez (b. 1945). After briefly presenting the topic, it discusses the differences between sculpture and artifacts. Focusing on these differences, it argues for a shared problematic held by some of Herminio's sculptures and certain philosophical ideas.

Interplay between one-particle and collective degrees of freedom in nuclei

, 2016
Some developments of nuclear-structure physics uniquely related to Copenhagen School are sketched based on theoretical considerations versus experimental findings and one-particle versus collective aspects.
