FUZZY DELAY DIFFERENTIAL EQUATIONS WITH HYBRID SECOND AND THIRD ORDERS RUNGE-KUTTA METHOD [PDF]
Journal of Engineering Science and Technology, 2018 This paper considers fuzzy delay differential equations with known statedelays. A dynamic problem is formulated by time-delay differential equations and an efficient scheme using a hybrid second and third orders Runge-Kutta method is developed and ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

A Stochastic Model for Fog Forecasting
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Despite significant advancements in parameterizations of boundary layer processes, forecasting, and nowcasting low‐level clouds using numerical models remain challenging. The purpose of this study is to test a prototype of a high‐resolution stochastic‐deterministic model designed to simulate the life cycle of fog cover based on the Ising model

Composite symplectic Runge-Kutta(-Nystrom) methods
, 1997 Non reducible composite Runge--Kutta methods can't be symplectic. For non reducible composite symplectic Runge--Kutta--Nystr\"om methods the order barrier is shown to be ...

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 9, Page 1932-1944, September 2026.This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Strong Stability Preserving Two-Derivative Two-Step Runge-Kutta Methods
MathematicsIn this study, we introduce the explicit strong stability preserving (SSP) two-derivative two-step Runge-Kutta (TDTSRK) methods. We propose the order conditions using Albrecht’s approach, comparing to the order conditions expressed in terms of rooted ...

Advanced Science, Volume 13, Issue 53, 24 September 2026.A programmable coupled‐resonator‐induced transparency (CRIT) platform is proposed, generalizing classical electromagnetically induced transparency (EIT) via a spinor representation. By utilizing dual‐channel gauge fields and universal unitary operations, this architecture enables dynamically engineered, reconfigurable slow‐light bands on a silicon ...
