Potts models on hierarchical lattices and Renormalization Group dynamics [PDF]

open access: yes, 2008
We prove that the generator of the renormalization group of Potts models on hierarchical lattices can be represented by a rational map acting on a finite-dimensional product of complex projective spaces. In this framework we can also consider models with

Quantifying Athermality and Quantum Induced Deviations from Classical Fluctuation Relations

open access: yesEntropy, 2020
In recent years, a quantum information theoretic framework has emerged for incorporating non-classical phenomena into fluctuation relations. Here, we elucidate this framework by exploring deviations from classical fluctuation relations resulting from the

Dynamics near QCD critical point by dynamic renormalization group [PDF]

open access: yes, 2011
We work out the basic analysis of dynamics near QCD critical point (CP) by dynamic renormalization group (RG). In addition to the RG analysis by coarse graining, we construct the nonlinear Langevin equation as a basic equation for the critical dynamics ...

Coxeter Groups and Asynchronous Cellular Automata [PDF]

open access: yes, 2010
The dynamics group of an asynchronous cellular automaton (ACA) relates properties of its long term dynamics to the structure of Coxeter groups. The key mathematical feature connecting these diverse fields is involutions.

A Quantum-Classical Brackets from p-Mechanics [PDF]

open access: yes, 2005
We provide an answer to the long standing problem of mixing quantum and classical dynamics within a single formalism. The construction is based on p-mechanical derivation (quant-ph/0212101, quant-ph/0304023) of quantum and classical dynamics from the ...

Active learning for regression in engineering populations: a risk-informed approach

open access: yesData-Centric Engineering
Regression is a fundamental prediction task common in data-centric engineering applications that involves learning mappings between continuous variables.

Graphical Analysis of Social Group Dynamics

open access: yes, 2013
Identifying communities in social networks becomes an increasingly important research problem. Several methods for identifying such groups have been developed, however, qualitative analysis (taking into account the scale of the problem) still poses ...

Model reproduces individual, group and collective dynamics of human contact networks [PDF]

open access: yes, 2016
Empirical data on the dynamics of human face-to-face interactions across a variety of social venues have recently revealed a number of context-independent structural and temporal properties of human contact networks.

Semi-Implicit Finite Volume Procedure for Compositional Subsurface Flow Simulation in Highly Anisotropic Porous Media

open access: yesFluids, 2021
Subsurface multiphase flow in porous media simulation is extensively used in many disciplines. Large meshes with non-orthogonalities (e.g., corner point geometries) and full tensor highly anisotropy ratios are usually required for subsurface flow ...

Individual and Group Dynamics in Purchasing Activity

open access: yes, 2010
As a major part of the daily operation in an enterprise, purchasing frequency is of constant change. Recent approaches on the human dynamics can provide some new insights into the economic behaviors of companies in the supply chain.
