Extended Jacobi Elliptic Function Expansion Method to the ZK-MEW Equation

International Journal of Differential Equations, 2011
The extended Jacobi elliptic function expansion method is applied for Zakharov-Kuznetsov-modified equal-width (ZK-MEW) equation. With the aid of symbolic computation, we construct some new Jacobi elliptic doubly periodic wave solutions and the ...

Ectomycorrhizal fungal community succession and fragmentation across forest edges nearly three decades postharvest

PLANTS, PEOPLE, PLANET, EarlyView.
Forest management for wood products involves the conversion of primary forests to younger plantations. This has an immediate impact on biota such as ectomycorrhizal fungi, a diverse symbiotic fungal community. Alternatives to large clearcuts may be one way to mitigate harvesting effects.

Spectrum of Lyapunov exponents in non-smooth systems evaluated using orthogonal perturbation vectors

MATEC Web of Conferences, 2018
This paper covers application of the novel method of Lyapunov exponents (LEs) spectrum estimation in non smooth mechanical systems. In the presented method, LEs are obtained from a Poincaré map.

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

Fortschritte der Physik, EarlyView.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Numerical Solution of Fuzzy Fractional Pharmacokinetics Model Arising from Drug Assimilation into the Bloodstream

Abstract and Applied Analysis, 2013
We propose a Jacobi tau method for solving a fuzzy fractional pharmacokinetics. This problem can model the concentration of the drug in the blood as time increases. The proposed approach is based on the Jacobi tau (JT) method.

A Physics‐Informed Learning Framework to Solve the Infinite‐Horizon Optimal Control Problem

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT We propose a physics‐informed neural networks (PINNs) framework to solve the infinite‐horizon optimal control problem of nonlinear systems. In particular, since PINNs are generally able to solve a class of partial differential equations (PDEs), they can be employed to learn the value function of the infinite‐horizon optimal control problem via

Impact of Video Distraction on Anxiety During Anesthesia Induction in Pediatric Patients Premedicated With Midazolam: A Randomized Controlled Trial. [PDF]

Paediatr Anaesth
ABSTRACT Background Midazolam is commonly used and effective in reducing preoperative anxiety in children. Nonpharmacological interventions, such as video distraction, are also well established for alleviating preoperative anxiety in pediatric patients, particularly those treated in ambulatory settings.

F-Expansion Method and Its Application for Finding New Exact Solutions to the Kudryashov-Sinelshchikov Equation

Journal of Applied Mathematics, 2013
Based on the F-expansion method, and the extended version of F-expansion method, we investigate the exact solutions of the Kudryashov-Sinelshchikov equation. With the aid of Maple, more exact solutions expressed by Jacobi elliptic function are obtained.
