International Journal for Numerical Methods in Fluids, Volume 97, Issue 9, Page 1189-1208, September 2025.This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

One step multiderivative methods for first order ordinary differential equations [PDF]
, 1981 A family of one-step multiderivative methods based on Padé approximants to the exponential function is developed. The methods are extrapolated and analysed for use in PECE mode.

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 7, July 2025.Abstract Planetary flows are shaped by interactions at scales much smaller than the flows themselves, with mesoscale and sub–mesoscale eddies playing key roles in mixing, particle transport and tracer dispersion. To capture these effects, we introduce a stochastic formulation of the primitive equations within the Location Uncertainty (LU) framework ...

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

Engineering Reports, Volume 7, Issue 3, March 2025.This study compares one‐step and multi‐step numerical methods for draining a water tank, assessing accuracy, stability, computational time, and memory. Multi‐step methods offer greater efficiency but require careful initialization and are more memory‐intensive.
