Comparative AI‐Based Framework for Name‐Based Demographic Inference in the Indian Subcontinent

Engineering Reports, Volume 8, Issue 6, June 2026.
A multi‐task framework of five AI models (SVM, XGBoost, LightGBM, BiLSTM, and XLM‐RoBERTa) infers nationality, religion, and gender from personal names across seven Indian subcontinent countries. Character‐level TF‐IDF with SVM achieves the highest accuracy: 83.23% for nationality, 92.94% for religion, and 92.67% for gender across 7581 names.

A Lanczos-powered implementation of the Faber polynomial quantum time propagator for reaction probabilities [PDF]

, 2004
Complementing our recent work on subspace wavepacket propagation [Chem. Phys. Lett. 336 (2001) 149], we introduce a Lanczos-based implementation of the Faber polynomial quantum long-time propagator. The original version [J. Chem. Phys.

Polymer informatics: Integrating data‐driven strategies, advanced machine learning, and automated synthesis for next‐generation polymer design

InfoScience, Volume 3, Issue 2, June 2026.
Designing new polymers for applications such as sustainable plastics, biomaterials, and 3D printing has traditionally been slow and expensive, relying heavily on trial‐and‐error experiments. This review shows how polymer informatics—the integration of large polymer databases, machine‐learning models, and automated robotic synthesis—enables fast ...

Gram Decay and Intrinsic Dimensions of Krylov Subspaces

Numerical Linear Algebra with Applications, Volume 33, Issue 3, June 2026.
ABSTRACT Krylov subspace methods solve large sparse linear systems Ax=b$$ Ax=b $$ by building a sequence of polynomial approximations to A−1b$$ {A}^{-1}b $$ from successive matrix‐vector products. In finite precision, the number of numerically independent directions that can be extracted from this sequence is bounded by the intrinsic information ...

On the some subclasses of bi-univalent functions related to the Faber polynomial expansions and the Fibonacci numbers

Rendiconti di Matematica e delle Sue Applicazioni, 2020
Summary: In this investigation, by using the Tremblay fractional derivative operator, we introduce the new class \(\mathfrak{I}^{\mu,\rho}_{\Sigma,\gamma} (\widetilde{\mathfrak{p}})\) of bi-univalent functions based on the rule of subordination. Moreover, we use the Faber polynomial expansions and Fibonacci numbers to derive bounds for the general ...

Rigidity of balls in the solid mean value property for polyharmonic functions

Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We show that balls are the only open bounded domains for which the mean value formula for polyharmonic functions holds. We do so by adapting an argument of Ü. Kuran for harmonic functions. We also, provide a quantitative version of the same result.

The Faber–Manteuffel theorem for linear operators [PDF]

, 2017
A short recurrence for orthogonalizing Krylov subspace bases for a matrix A exists if and only if the adjoint of A is a low-degree polynomial in A (i.e., A is normal of low degree).

From Farm to Table: Multifactorial Determinants of Dietary Diversity and Food Security Within Sustainable Rice‐Producing Systems in Bangladesh

eFood, Volume 7, Issue 2, April 2026.
This study examines the factors influencing dietary diversity and food security in rural Bangladesh, emphasizing the roles of income and crop diversification. Findings highlight that larger farms, diversified income, and access to agricultural services improve food security, while larger households and greater market distances increase food insecurity.

Rapid Decreases and Performance Declines in Northeast Pacific Seamount Foundation Species Detected in an Oxygen Minimum Zone

Global Change Biology, Volume 32, Issue 4, April 2026.
Across 12 long‐term monitoring sites on three Northeast Pacific seamounts, 163 of 844 cold‐water coral and sponge individuals were lost between surveys 3–5 years apart, with abundance declining at five sites and condition (i.e., health) declining at nine.

On the orthogonality of Atkin-like polynomials and orthogonal polynomial expansion of generalized Faber polynomials

, 2023
In this paper, we consider the Atkin-like polynomials that appeared in the study of normalized extremal quasimodular forms of depth 1 on $SL_{2}(\mathbb{Z})$ by Kaneko and Koike as orthogonal polynomials and clarify their properties. By considering Atkin-
