Efficient Tensor Completion Algorithms for Highly Oscillatory Operators

Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.
ABSTRACT We address the problem of recovering highly oscillatory operators, represented as n×n$$ n\times n $$ matrices with a fixed set of observed entries. Given that these matrices can be well compressed by butterfly matrix decomposition of L=𝒪(logn) levels requiring only O(nlogn)$$ O\left(n\log n\right) $$ degrees of freedom, we propose a novel ...

Some properties of generalized strongly harmonic convex functions

International Journal of Analysis and Applications, 2018
Summary: In this paper, we introduce a new class of harmonic convex functions with respect to an arbitrary trifunction \(F(\cdot,\cdot,\cdot): K\times K\times[0,1]\to\mathbb{R}\), which is called generalized strongly harmonic convex functions. We study some basic properties of strongly harmonic convex functions.

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, Volume 104, Issue 5, Page 498-509, August 2026.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Fast and Accurate GPU‐Accelerated Computation of Two‐Electron Four‐Center Coulomb Repulsion Integrals

Journal of Computational Chemistry, Volume 47, Issue 20, July 30, 2026.
Our GPU software rapidly and accurately computes two‐electron, four‐center Coulomb repulsion integrals using Slater‐type orbitals. It involves applying a simple transformation to eliminate the Coulomb singularity and using the trapezoidal quadrature rule. The quadrature rule converges rapidly, as demonstrated in this graph.

Generalized \((h,r)\)-harmonic convex functions and inequalities

International Journal of Analysis and Applications, 2018
Summary: The main aim of this paper is to introduce a new class of harmonic convex functions with respect to non-negative function \(h\), which is called generalized \((h,r)\)-harmonic convex functions. We derive some new Fejer-Hermite-Hadamard type inequalities for generalized harmonic convex functions. Some special cases are also discussed. The ideas

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Optical Phased Arrays on Photonic Integrated Circuit Platforms: Challenges, Opportunities, and Future Applications

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...
