Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

EVSS‐Based Simulation Techniques for the Viscoelastic Fluids With Pure Polymer Melts Using Three‐Field Approach

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This paper presents a finite element method for simulating highly viscoelastic flows of pure polymer melts using the Elastic Viscous Stress Splitting formulation. The method avoids higher‐order derivatives in the weak formulation by reformulating the convective term in the constitutive equation.

Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

Prospective randomised controlled trial comparing PLLA and PLDLA/HA/β‐TCP interference screws in anterior cruciate ligament reconstruction: CT scans, MRI and clinical outcomes

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modifying interference screw composition may ensure better osteoconductive properties in order to reduce tunnel enlargement after anterior cruciate ligament (ACL) reconstruction. The primary and secondary purposes were to evaluate tunnel and screw volume changes in poly‐L‐lactide acid (PLLA) and poly‐D‐lactic acid + hydroxyapatite + β ...

Pupil Plane Multiplexing for Vectorial Fourier Ptychography

open access: yesLaser &Photonics Reviews, EarlyView.
This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.
