Tight Bounds for Hypercube Minor‐Universality
Journal of Graph Theory, Volume 112, Issue 4, Page 433-437, August 2026.ABSTRACT A graph G is m‐minor‐universal if every graph H with at most m edges and no isolated vertices is contained as a minor in G. Recently, Benjamini, Kalifa and Tzalik proved that there is an absolute constant c > 0 such that the d‐dimensional hypercube Q d is ( c ⋅ 2 d / d)‐minor‐universal, while there is an absolute constant K > 0 such that Q d ...

Dynamic Mode Decomposition (DMD) for Low‐Latency Real‐Time Cardiac MRI
Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 623-634, August 2026.ABSTRACT Purpose To demonstrate dynamic mode decomposition (DMD) for high spatiotemporal low‐latency online reconstruction in 2D real‐time cardiac MRI. Methods DMD was applied to 2D spiral balanced steady state free precession (bSSFP) real‐time adult and fetal cardiac MRI at 0.55 T, with data from 10 healthy adult volunteers (3F/7M; age: 21–49; BMI: 20–

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case
The Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3775-3795, July 2026.Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 7, July 2026.We present an automated CT‐to‐simulation workflow to estimate structural response and fracture risk in metastasis‐affected vertebrae. Deep learning performs vertebral identification and segmentation, while CPD assigns geometry‐aware boundary conditions.

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver
International Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Observations of Electric Fields Sounding in the Mature Stage of a Thunderstorm
Geoscience Data Journal, Volume 13, Issue 3, July 2026.Successive electric field soundings separated by only 6 min provided a rare view of charge structure of a mature thunderstorm. The observations reveal horizontally inhomogeneous charge regions, an unusually deep upper negative layer, and charge features that cannot be readily explained by current thunderstorm electrification mechanisms. ABSTRACT In the
