A Geometric Multigrid Preconditioner for Discontinuous Galerkin Shifted Boundary Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 21, 15 November 2026.
ABSTRACT I introduce a geometric multigrid preconditioner for the Shifted Boundary Method (SBM) designed to solve PDEs on complex geometries. While the SBM simplifies mesh generation by using a nonconforming background grid, it often results in nonsymmetric linear systems, a complete analysis of which is missing from the literature, especially with ...

Bridging the Scalability Gap: From the Fourth Paradigm to Interconnected Discovery Ecosystems in Perovskite Photovoltaics

Advanced Energy and Sustainability Research, Volume 7, Issue 11, November 2026.
Perovskite photovoltaics face persistent challenges in stability, reproducibility, data fragmentation, and scale‐up. An interconnected discovery ecosystem is proposed to bridge the gap between prediction and experimental realization by integrating AI‐assisted design, autonomous experimentation, physical–digital synchronization, provenance‐aware data ...

How Allometry and Sexual Dimorphism Influence Cortical Bone Morphology at the Mandibular Symphysis in Modern Humans: A Comparative Study Using Elliptic Fourier Descriptors

American Journal of Biological Anthropology, Volume 191, Issue 3, November 2026.
ABSTRACT Objectives The modern human mandibular symphysis displays a mental prominence, a unique trait in the human lineage. Beyond this shared pattern, considerable variability in shape and metrics exists. This heterogeneity is thought to result from multiple mechanisms, including biomechanical compensation, allometric and dietary effects, population ...

Proton NMR Revisited: Negative Time Reconstruction Transforms Pure Shift and 2D J‐Spectroscopy

Chemistry–Methods, Volume 6, Issue 11, November 2026.
Negative time signal reconstruction of NMR data acquired in a modified spin echo distills complex spectra into enhanced resolution multiplets and a pure shift spectrum. Experiments typically take only 2 min, with sensitivity an order of magnitude better than current methods, making routine acquisition of pure shift NMR spectra practical. Proton nuclear
