On the ideal weights for WENO/WENO-like finite difference schemes for the first derivative, I
, 2020 An interesting fact which was used in the construction of targeted essentially non-oscillatory (TENO) schemes is that a (n + 1)th order accurate scheme can be written as a linear combination of two nth order accurate schemes.

Medical Physics, Volume 53, Issue 6, June 2026.Abstract Background Non‐invasive imaging‐based assessment of blood flow plays a critical role in evaluating heart function and structure. Computed Tomography (CT) is a widely‐used imaging modality that can robustly evaluate cardiovascular anatomy and function, but direct methods to estimate blood flow velocity from movies of contrast dynamics have not ...

DJ4Earth: Differentiable, and Performance‐Portable Earth System Modeling via Program Transformations
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.Abstract Differentiable Earth system models (ESMs) enable powerful applications such as sensitivity analysis, gradient‐based calibration, state estimation, boundary flux inversions, uncertainty quantification, and online machine learning. Reverse‐mode automatic differentiation (AD) efficiently provides gradients for such tasks, yet models have rarely ...

Third Order Reconstruction of the KP Scheme for Model of River Tinnelva [PDF]
Modeling, Identification and Control, 2017 The Saint-Venant equation/Shallow Water Equation is used to simulate flow of river, flow of liquid in an open channel, tsunami etc. The Kurganov-Petrova (KP) scheme which was developed based on the local speed of discontinuity propagation, can be used to

Particle Size Effects on Dynamic Behavior of Heated Spheroidal Particles in Shear Flow
Chemical Engineering &Technology, Volume 49, Issue 3, March 2026.Understanding the dynamics of nonspherical particles in shear‐driven flows is essential for a wide range of engineering applications. This study examines how confinement ratio, thermal effects, and interparticle interactions influence the migration, equilibrium positions, and rotation of nonspherical particles in such flows.

Energetics of the Upper‐Ocean Under Sea Ice: Frictional Dissipation Versus Baroclinic Production
Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.Abstract In polar regions, the presence of sea ice is known to reduce the ocean's eddy kinetic energy (EKE) by enhancing frictional dissipation at the surface. Here, using a coupled ocean—sea ice model, we discuss a mechanism that can instead increase EKE generation under sea ice and, in our simulations, compensates surface dissipation by 69% to 30 ...

WENO schemes with Lax–Wendroff type time discretizations for Hamilton–Jacobi equations [PDF]
, 2007 In this paper, a class of weighted essentially non-oscillatory (WENO) schemes with a Lax–Wendroff time discretization procedure, termed WENO-LW schemes, for solving Hamilton–Jacobi equations is presented.
