A Literature Review of Securities Holdings Statistics Research and A Practitioner's Guide
Journal of Economic Surveys, Volume 40, Issue 2, Page 632-658, April 2026.ABSTRACT Granular holdings data containing security‐by‐security portfolio investments features prominently in economics and finance research. One novel source is the granular Securities Holdings Statistics (SHS), managed by the European Central Bank. SHS covers different euro area investors with over 2 billion observations, representing +50 trillion ...

Starch Synthase 3 isoforms are essential for normal starch granule initiation in wheat endosperm
New Phytologist, Volume 250, Issue 2, Page 1075-1091, April 2026.Summary Wheat grains have two distinct types of starch granules. Large, lenticular A‐type granules are formed from a single initiation per amyloplast during early grain development, while numerous small B‐type granules are initiated during later grain development.

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach
Mathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4184-4197, 30 March 2026.ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

C∞‐Structures for Liénard Equations and New Exact Solutions to a Class of Klein–Gordon Equations
Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2795-2822, 15 March 2026.ABSTRACT Liénard equations are analyzed using the recent theory of 𝒞∞‐structures. For each Liénard equation, a 𝒞∞‐structure is determined by using a Lie point symmetry and a 𝒞∞‐symmetry. Based on this approach, a novel method for integrating these equations is proposed, which consists in solving sequentially two completely integrable Pfaffian equations.

Self‐Assembled Fluorescent Nanodiamond Layers for Quantum Imaging
Advanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.We developed a simple, scalable method for coating surfaces with fluorescent nanodiamonds. By optimizing the coating process, we created uniform, dense layers that enable high‐resolution magnetic imaging using the nitrogen‐vacancy (NV) center in nanodiamonds. This approach enables the development of cost‐effective quantum‐sensing and imaging substrates
