On Bergman–Toeplitz operators in periodic planar domains
Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract We study spectra of Toeplitz operators Ta$T_a$ with periodic symbols in Bergman spaces A2(Π)$A^2(\Pi)$ on unbounded singly periodic planar domains Π$\Pi$, which are defined as the union of infinitely many copies of the translated, bounded periodic cell ϖ$\varpi$.

Quantitative Biology, Volume 13, Issue 3, September 2025.Abstract It is challenging to identify comorbidity patterns and mechanistically investigate disease associations based on health‐related data that are often sparse, large‐scale, and multimodal. Adopting a systems biology approach, embedding‐based algorithms provide a new perspective to examine diseases under a unified framework by mapping diseases into

Stencil Computations on AMD and Nvidia Graphics Processors: Performance and Tuning Strategies
Concurrency and Computation: Practice and Experience, Volume 37, Issue 12-14, 25 June 2025.ABSTRACT Over the last ten years, graphics processors have become the de facto accelerator for data‐parallel tasks in various branches of high‐performance computing, including machine learning and computational sciences. However, with the recent introduction of AMD‐manufactured graphics processors to the world's fastest supercomputers, tuning ...

A Subbuteo‐Inspired Rolling Isolation System for Protecting Rigid Blocks
Earthquake Engineering &Structural Dynamics, Volume 54, Issue 7, Page 1918-1933, June 2025.ABSTRACT This study investigates a Subbuteo‐inspired rolling isolation system (RIS) as an effective means for protecting rigid blocks. The block is assumed to be rigidly connected to a curved base sector, allowing it to roll back and forth freely under dynamic excitations. The intrinsic trait of the proposed isolation concept is that the rigid block is

A High‐Order Hybrid‐Spectral Incompressible Navier–Stokes Model for Non‐Linear Water Waves
International Journal for Numerical Methods in Fluids, Volume 97, Issue 6, Page 1009-1021, June 2025.We present a high‐order accurate CFD model for simulating nonlinear water waves using the incompressible Navier–Stokes equations. The model employs a combined Chebyshev–Fourier basis for efficient spatial discretization, and a low‐storage fourth‐order Runge–Kutta method for temporal integration. A Poisson pressure problem is solved using a geometric p$$

Sparse graph signals – uncertainty principles and recovery
GAMM-Mitteilungen, Volume 48, Issue 2, June 2025.ABSTRACT We study signals that are sparse either on the vertices of a graph or in the graph spectral domain. Recent results on the algebraic properties of random integer matrices as well as on the boundedness of eigenvectors of random matrices imply two types of support size uncertainty principles for graph signals.

Putatively Optimal Projective Spherical Designs With Little Apparent Symmetry
Journal of Combinatorial Designs, Volume 33, Issue 6, Page 222-234, June 2025.ABSTRACT We give some new explicit examples of putatively optimal projective spherical designs, that is, ones for which there is numerical evidence that they are of minimal size. These form continuous families, and so have little apparent symmetry in general, which requires the introduction of new techniques for their construction.

More Creative Activities, Lower Creative Ability: Exploring an Unexpected PISA Finding
The Journal of Creative Behavior, Volume 59, Issue 2, June 2025.ABSTRACT Creative activities are typically thought to be positively associated with creative ability, whether because more creative individuals select into creative activities, or because those activities support the development of creativity, or both. However, the PISA 2022 creative thinking report revealed an unexpected finding: Creative ability was ...

Stabilized Krylov Subspace Recurrences via Randomized Sketching
Numerical Linear Algebra with Applications, Volume 32, Issue 3, June 2025.ABSTRACT Recurrences building orthonormal bases for polynomial Krylov spaces have been classically used for approximation purposes in various numerical linear algebra contexts. Variants aiming to limit memory and computational costs by using truncated recurrences often have convergence constraints.
