Fixed point problems of the Picard-Mann hybrid iterative process for continuous functions on an arbitrary interval

, 2013
In this paper, we consider the iteration method called 'Picard-Mann hybrid iterative process' for finding a fixed point of continuous functions on an arbitrary interval.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

The Longevity of Hybrid Identity Family Businesses

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, Volume 43, Issue 2, June 2026.
ABSTRACT This paper examines family firms that have endured for more than 100 years, focusing on how their hybrid identities, combining the normative values of the family with the utilitarian goals of the business, contribute to their longevity. We address two research questions: How do family firms achieve longevity beyond 100 years? How do long‐lived

Stability of Fixed Points of Partial Contractivities and Fractal Surfaces

Axioms
In this paper, a large class of contractions is studied that contains Banach and Matkowski maps as particular cases. Sufficient conditions for the existence of fixed points are proposed in the framework of b-metric spaces.

Deep Picard Iteration for High-Dimensional Nonlinear PDEs

SIAM Journal on Scientific Computing
We present the Deep Picard Iteration (DPI) method, a new deep learning approach for solving high-dimensional partial differential equations (PDEs). The core innovation of DPI lies in its use of Picard iteration to reformulate the typically complex training objectives of neural network-based PDE solutions into much simpler, standard regression tasks ...

Putative Genomic Signatures of Local Adaptation in Five Local Indonesian Sheep Reveal Selection on Immunity, Reproduction, and Production Traits

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We determined the genetic structure and signatures of selection in five local Indonesian sheep breeds using genome‐wide SNP data. By integrating population structure analyses with runs of homozygosity and haplotype‐based selection scans, we identified breed‐specific genomic regions associated with immunity, reproduction, pigmentation, metabolism, and ...

A New Fixed-Point Framework for Nonexpansive and Averaged Mappings in Normed GE-Algebras

Journal of Mathematics
In this paper, we develop a systematic framework for studying fixed-point theory in the setting of normed GE-algebras. Building on the GE-norm, we introduce and analyze nonexpansive mappings, α-averaged mappings, and enriched contractions with respect to

Coupled Clustering in Hierarchical Matrices for the Oseen Problem

International Journal for Numerical Methods in Fluids, Volume 98, Issue 6, Page 751-765, June 2026.
Fluid flow problems can be modelled by the Navier‐Stokes or, after linearization, by the Oseen equations. Their discretization results in linear systems in saddle point form which are typically very large and need to be solved iteratively. We propose a novel block structure for hierarchical matrices which is then used to build preconditioners for the ...

Numerical results of fractional order difference system for norovirus disease with feedback neural networking

Boundary Value Problems
In this article, we study and analyze a novel discrete SEAIRF compartmental model in the Caputo sense to investigate the complex transmission dynamics of Norovirus, a highly infectious pathogen known for its strong environmental persistence. We carefully
