On the Geodesic Form of Non-Relativistic Dynamic Equations [PDF]
, 1999 It is shown that any second order dynamic equation on a configuration bundle $Q\to R$ of non-relativistic mechanics is equivalent to a geodesic equation with respect to a (non-linear) connection on the tangent bundle $TQ\to Q$.

Dynamic Structural Equation Models
Structural Equation Modeling: A Multidisciplinary Journal, 2017 This article presents dynamic structural equation modeling (DSEM), which can be used to study the evolution of observed and latent variables as well as the structural equation models over time. DSEM is suitable for analyzing intensive longitudinal data where observations from multiple individuals are collected at many points in time.

Dynamic Programming Equation for the Mean Field Optimal Stopping Problem [PDF]
SIAM Journal of Control and Optimization, 2021 We study the optimal stopping problem of McKean-Vlasov diffusions when the criterion is a function of the law of the stopped process. A remarkable new feature in this setting is that the stopping time also impacts the dynamics of the stopped process ...

Application of Projection Operator Method to Coarse-Grained Dynamics with Transient Potential [PDF]
Phys. Rev. E 105, 044117 (2022), 2022 We show that the coarse-grained dynamics model with the time-dependent and fluctuating potential (transient potential) can be derived from the microscopic Hamiltonian dynamics. The concept of the transient potential was first introduced rather phenomenologically, and its relation to the underlying microscopic dynamics has not been clarified yet.

Fractal and Fractional, 2021 In this article, we construct the exact dynamical wave solutions to the Date–Jimbo–Kashiwara–Miwa equation with conformable derivative by using an efficient and well-established approach, namely: the two-variable G’/G, 1/G-expansion method.

Existence results for some generalized Sigmoid Beverton-Holt models in time scales
Nonautonomous Dynamical Systems, 2023 In this article, we investigate some generalized Sigmoid Beverton-Holt models in time scales, and we obtain the existence and uniqueness of a globally attractive almost periodic solution to the associated dynamic equations with or without survival rates ...
