Comparison Between Phenomenological and Fiber-Section Non-linear Models
Frontiers in Built Environment, 2020 The prediction of the seismic response of structures requires accurate models for describing the behavior of each structural element. In frame analysis, non-linearities are typically modeled through either lumped or distributed plasticity elements ...

Bridging Mechanistic and Phenomenological Models of Complex Biological Systems.
PLoS Computational Biology, 2016 The inherent complexity of biological systems gives rise to complicated mechanistic models with a large number of parameters. On the other hand, the collective behavior of these systems can often be characterized by a relatively small number of ...

Wormholes and masses for Goldstone bosons
Journal of High Energy Physics, 2019 There exist non-trivial stationary points of the Euclidean action for an axion particle minimally coupled to Einstein gravity, dubbed wormholes. They explicitly break the continuos global shift symmetry of the axion in a non-perturbative way, and ...

Phenomenological Modeling of Shape Memory Alloys: A Review of Macroscopic Approaches [PDF]
MicromachinesShape Memory Alloys (SMAs) have unique thermomechanical properties, including superelasticity and the shape memory effect, which has led them to be used in a wide range of applications, from biomedical devices to aerospace and civil engineering ...

No-Signaling in Steepest Entropy Ascent: A Nonlinear, Non-Local, Non-Equilibrium Quantum Dynamics of Composite Systems Strongly Compatible with the Second Law [PDF]
EntropyLindbladian formalism models open quantum systems using a ‘bottom-up’ approach, deriving linear dynamics from system–environment interactions. We present a ‘top-down’ approach starting with phenomenological constraints, focusing on a system’s structure ...

Prediction of Permeate Flux in Ultrafiltration Processes: A Review of Modeling Approaches
Membranes, 2021 In any membrane filtration, the prediction of permeate flux is critical to calculate the membrane surface required, which is an essential parameter for scaling-up, equipment sizing, and cost determination.

The dipole picture and the non-relativistic expansion [PDF]
EPJ Web of Conferences, 2022 We study exclusive quarkonium production in the dipole picture at next-to-leading order (NLO) accuracy, using the non-relativistic expansion for the quarkonium wavefunction.

High quality Nelson-Barr solution to the strong CP problem with θ = π
Journal of High Energy Physics, 2021 We discuss composite UV completions of the Nelson-Barr(NB) solution to the strong CP problem. In our construction, the CP symmetry is broken spontaneously by the dynamics of a hidden QCD at θ = π.

Symmetries for the 4HDM: extensions of cyclic groups
Journal of High Energy Physics, 2023 Multi-Higgs models equipped with global symmetry groups, either exact or softly broken, offer a rich framework for constructions beyond the Standard Model and lead to remarkable phenomenological consequences.
