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.

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.

Advanced Materials, Volume 38, Issue 41, 22 July 2026.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...
