Identifying Out‐of‐Voxel Echoes in Edited MRS With Phase Cycle Inversion
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1921-1933, April 2026.ABSTRACT Purpose To identify the origin of out‐of‐voxel (OOV) signals based on the coherence transfer pathway (CTP) formalism using signal phase conferred by the acquisition phase cycling scheme. Knowing the CTP driving OOV artifacts enables optimization of crusher gradients to improve their suppression.

Multi-Unitary Complex Hadamard Matrices
Open Systems & Information DynamicsWe analyze the set of real and complex Hadamard matrices with additional symmetry constrains. In particular, we link the problem of existence of maximally entangled multipartite states of [Formula: see text] subsystems with [Formula: see text] levels each to the set of complex Hadamard matrices of order [Formula: see text]. To this end, we investigate

Accelerating Conjugate Gradient Solvers for Homogenization Problems With Unitary Neural Operators
International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.ABSTRACT Rapid and reliable solvers for parametric partial differential equations (PDEs) are needed in many scientific and engineering disciplines. For example, there is a growing demand for composites and architected materials with heterogeneous microstructures.

Robust Parameter Designs Constructed from Hadamard Matrices
StatsThe primary objective of robust parameter design (RPD) is to determine the optimal settings of control factors in a system to minimize response variance while achieving a desirable mean response.

Breaking Barriers in High‐Order Spectral Methods: The Intrinsic Matrix Approach
International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.ABSTRACT This paper introduces a unified framework in Hilbert spaces for applying high‐order differential operators in bounded domains using Chebyshev, Legendre, and Fourier spectral methods. By exploiting the banded structure of differentiation matrices and embedding boundary conditions directly into the operator through a scaling law relating ...

Spectral Decomposition of Chemical Semantics for Activity Cliffs‐Aware Molecular Property Prediction
Advanced Science, Volume 13, Issue 13, 3 March 2026.PrismNet mimics chemical intuition by functioning as a computational prism, refracting molecular graphs into complementary semantic views and spectral frequencies. This dual‐decomposition strategy effectively captures both global topologies and subtle “activity cliff” perturbations.

Crop Science, Volume 66, Issue 2, March/April 2026.Abstract Genomic prediction (GP)‐based sparse testing allows evaluation of more genotypes within a fixed budget in multi‐environment trials (METs), thereby reducing phenotyping costs. It assesses untested genotype–environment combinations using varying training sets and allocation schemes.
