Links Between Different Models for Multifragmentation [PDF]
arXiv, 1996 We establish links between three different models for multifragmentation: the percolation model, the lattice gas model and the statistical multifragmentation model. There are remarkable similarities between the lattice gas model and the statistical multifragmentation model.

CURRENT STATUS OF e⁺e⁻→π⁺π⁻η STUDY. EXPERIMENT AND THEORY
East European Journal of Physics, 2018 In this note I review the current status of electron-positron annihilation into the π⁺π⁻η final state from both experimental and theoretical sides. The theoretical studies of the reaction are discussed in framework of three theoretical approaches: the ...

Critical chiral hypersurface of the magnetized NJL model
Nuclear Physics B, 2018 In pursuit of sketching the effective magnetized QCD phase diagram, we find conditions on the critical coupling for chiral symmetry breaking in the Nambu–Jona-Lasinio model in a nontrivial thermo-magnetic environment.

Model selection criteria for nonlinear mixed effects modeling [PDF]
arXiv, 2014 We consider constructing model selection criteria for evaluating nonlinear mixed effects models via basis expansions. Mean functions and random functions in the mixed effects model are expressed by basis expansions, then they are estimated by the maximum likelihood method.

QCD critical end point from a realistic PNJL model
EPJ Web of Conferences, 2018 With parameters fixed by critical temperature and equation of state at zero baryon chemical potential, a realistic Polyakov-Nambu-Jona-Lasinio (rPNJL) model predicts a critical end point of chiral phase transition at (μEB = 720MeV; TE = 93MeV).

Comparing Semi-Parametric Model Learning Algorithms for Dynamic Model Estimation in Robotics [PDF]
arXiv, 2019 Physical modeling of robotic system behavior is the foundation for controlling many robotic mechanisms to a satisfactory degree. Mechanisms are also typically designed in a way that good model accuracy can be achieved with relatively simple models and model identification strategies.

Automated Statistical Model Discovery with Language Models [PDF]
arXivStatistical model discovery is a challenging search over a vast space of models subject to domain-specific constraints. Efficiently searching over this space requires expertise in modeling and the problem domain. Motivated by the domain knowledge and programming capabilities of large language models (LMs), we introduce a method for language model ...

Exploring Actions, Interactions and Challenges in Software Modelling Tasks: An Empirical Investigation with Students [PDF]
arXivBackground: Software modelling is a creative yet challenging task. Modellers often find themselves lost in the process, from understanding the modelling problem to solving it with proper modelling strategies and modelling tools. Students learning modelling often get overwhelmed with the notations and tools.

Nambu–Jona-Lasinio model with a fractal inspired coupling
Physics Letters BThe Nambu–Jona-Lasino model is modified by the inclusion of a running-coupling that was obtained by a fractal approach to Quantum Chromodynamics. The coupling follows a q-exponential function and, in the context of high energy collisions, explains the ...
