Composite spiral waves in discrete-time systems.
Wang X, Gao J, Gu C, Wu D, Liu X, Shen C. Wang X, et al. Phys Rev E. 2023 Oct;108(4-1):044205. doi: 10.1103/PhysRevE.108.044205. Phys Rev E. 2023. PMID: 37978649
However, the study of spiral waves has been confined to continuous-time systems, while spiral waves in discrete-time systems have been rarely reported. In recent years, discrete-time models have been widely studied in ecology because of their appropriateness to syst …

Physics-informed neural networks for transcranial ultrasound wave propagation.
Wang L, Wang H, Liang L, Li J, Zeng Z, Liu Y. Wang L, et al. Ultrasonics. 2023 Jul;132:107026. doi: 10.1016/j.ultras.2023.107026. Epub 2023 Apr 28. Ultrasonics. 2023. PMID: 37137219
Transcranial ultrasound imaging has been playing an increasingly important role in the non-invasive treatment of brain disorders. However, the conventional mesh-based numerical wave solvers, which are an integral part of imaging algorithms, suffer from limitations such as …

Transition from chimera/solitary states to traveling waves.
Rybalova E, Muni S, Strelkova G. Rybalova E, et al. Chaos. 2023 Mar;33(3):033104. doi: 10.1063/5.0138207. Chaos. 2023. PMID: 37003811
We study numerically the spatiotemporal dynamics in a ring network of nonlocally coupled nonlinear oscillators, each represented by a two-dimensional discrete-time model of the classical van der Pol oscillator. It is shown that the discretized oscillator exhibits ri …

Hydrodynamic and Thermodynamic Nonequilibrium Effects around Shock Waves: Based on a Discrete Boltzmann Method.
Lin C, Su X, Zhang Y. Lin C, et al. Entropy (Basel). 2020 Dec 10;22(12):1397. doi: 10.3390/e22121397. Entropy (Basel). 2020. PMID: 33321966 Free PMC article.
A shock wave that is characterized by sharp physical gradients always draws the medium out of equilibrium. In this work, both hydrodynamic and thermodynamic nonequilibrium effects around the shock wave are investigated using a discrete Boltzmann model. Via Ch …

Learning of discrete models of variational PDEs from data.
Offen C, Ober-Blöbaum S. Offen C, et al. Chaos. 2024 Jan 1;34(1):013104. doi: 10.1063/5.0172287. Chaos. 2024. PMID: 38190372
For this, we train a neural network model of a discrete Lagrangian density such that the discrete Euler-Lagrange equations are consistent with the given training data. ...Minimization of the regularizers guarantees that close to the training dat …

Longitudinal Association Between Exclusive and Dual Use of Cigarettes and Electronic Nicotine Delivery Systems and Asthma Among U.S. Adolescents.
Patel A, Cook S, Mattingly DT, Barnes GD, Arenberg DA, Levy DT, Meza R, Fleischer NL, Hirschtick JL. Patel A, et al. J Adolesc Health. 2023 Sep;73(3):437-444. doi: 10.1016/j.jadohealth.2023.04.009. Epub 2023 Jun 10. J Adolesc Health. 2023. PMID: 37306645
We lagged the time-varying exposure variable by one wave and categorized respondents by current use status (1+ days in the past 30 days): never or non-current, exclusive cigarette, exclusive ENDS, and dual cigarette and ENDS use. We also controlled for sociodemographic (ag …
