Best Proximity Points of Relatively Jaggi Nonexpansive Mappings in Busemann Convex Spaces

open access: yesJournal of Function Spaces
In this paper, we introduce cyclic (noncyclic) relatively Jaggi nonexpansive mappings on Busemann convex spaces and investigate the existence of their best proximity points (pairs).

Asymptotic Behavior of Weak Solutions of Nonisothermal Flow of Herschel–Bulkley Fluid to Free Boundary

open access: yesDiscrete Dynamics in Nature and Society, 2022
In this manuscript, the behavior of a Herschel–Bulkley fluid has been discussed in a thin layer in ℝ3 associated with a nonlinear stationary, nonisothermal, and incompressible model.

Agent based cooperative theory formation in pure mathematics [PDF]

open access: yes, 2000
The HR program, Colton et al. (1999), performs theory formation in domains of pure mathematics. Given only minimal information about a domain, it invents concepts, make conjectures, proves theorems and finds counterexamples to false conjectures.

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

ADMITTING CENTER MAPS ON MULTIPLICATIVE METRIC SPACE [PDF]

open access: yesJournal of Algebraic Systems, 2020
‎In this work‎, ‎we investigate admitting center map on multiplicative metric space‎ ‎and establish some fixed point theorems for such maps‎. ‎We modify the Banach contraction principle and‎ ‎the Caristi's fixed point theorem for M-contraction ...

Magnetoactive Metamaterials: A State‐of‐the‐Art Review

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetoactive metamaterials combine magnetoactive composites with architected metastructures to enable contactless, tunable control of mechanical, acoustic, and elastic properties. This review highlights recent advances in their design, fabrication, and applications in soft robotics, biomedical devices, and adaptive structures and outlines future ...

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

Remark on Weil's conjectures

open access: yes, 2016
We introduce a cohomology theory for a class of projective varieties over a finite field coming from the canonical trace on a C*-algebra attached to the variety.

Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles

open access: yesAdvanced Engineering Materials, EarlyView.
Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

A Note on Anti-De Sitter Spaces as G-Manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences
We classify the orbits and orbit spaces of cohomogeneity two isometric actions of compact and connected Lie groups on anti-de Sitter spaces. We also give a more simple proof for the previously proven theorem about the similar classifications for ...
