Seeking for a Fundamental Quantum Arrow of Time: Time Reversal and the Symmetry-To-Reality Inference in Standard Quantum Mechanics

open access: yesFrontiers in Physics, 2018
In this paper I shall shed some doubts on a widely-held claim: standard quantum mechanics is time-reversal invariant, and thereby, blind to the direction of time.

Constraints On Unparticle Physics In Electroweak Gauge Boson Scattering

open access: yes, 2007
The existence of scale invariant physics would lead to new phenomena in particle physics that could be detected at the LHC. In this paper we exploit the effects of these unparticles in $WW \to WW$ scattering.

Discrete physics with conservation and Galilean invariance

open access: yesMathematical and Computer Modelling, 2003
In this paper, we show how to avoid continuum concepts altogether for both Newtonian mechanics and for special relativistic mechanics. For Newtonian mechanics, we will establish all the usual conservation laws. For both Newtonian mechanics and for special relativistic mechanics, we will prove Galilean invariance for inertial systems.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Physical invariants for nonlinear orthotropic solids

open access: yesInternational Journal of Solids and Structures, 2011
Seven invariants, with immediate physical interpretation, are proposed for the strain energy function of nonlinear orthotropic elastic solids. Three of the seven invariants are the principal stretch ratios and the other four are squares of the dot product between the two preferred directions and two principal directions of the right stretch tensor.

Performance Triggered Adaptive Model Reduction for Soil Moisture Estimation in Precision Irrigation

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT Accurate soil moisture information is essential for precise irrigation to enhance water use efficiency. Estimating soil moisture based on limited soil moisture sensors is especially critical for obtaining comprehensive soil moisture information when dealing with large‐scale agricultural fields.

Common origin of radiative neutrino mass, dark matter and leptogenesis in scotogenic Georgi-Machacek model

open access: yesNuclear Physics B, 2021
We explore the phenomenology of the Georgi-Machacek model extended with two Higgs doublets and vector fermion doublets invariant under SU(2)L×U(1)Y×Z4×Z2.
