Mechanical Metamaterial‐Based Structure with Magnetically Controlled Nonreversibility and Nonreciprocity for Programmable Locomotion

Advanced Science, EarlyView.
A magneto‐mechanical metamaterial‐based structure that simultaneously exhibits programmable nonreversibility and nonreciprocity. These cause substantial transitions in static mechanical properties, such as Poisson's ratio and stiffness, leading to stark changes in energy absorption.

Electrical Manipulation of Magnetic Domain Structure in van der Waals Ferromagnetic Fe3GaTe2 Using Ferroelectric PMN‐PT Single Crystal

Advanced Science, EarlyView.
2D van der Waals ferromagnets enable tunable magnetism for spintronics. This study demonstrates electric‐field‐induced control of Fe3GaTe2 magnetism on a PMN‐PT substrate, reducing coercive force and altering domain structures. The effects stem from interlayer gap modulation and enhanced DzyaloshinskiiMoriya interaction, establishing a path toward low ...

Fixed Point Theorem for Monotone Non-Expansive Mappings

International Journal of Analysis and Applications, 2021
In this paper, we study the fixed point theorem for monotone nonexpansive mappings in the setting of a uniformly smooth and uniformly convex smooth Banach space.

A Systematic Computational Framework for Practical Identifiability Analysis in Mathematical Models Arising from Biology

Advanced Science, EarlyView.
A systematic computational framework is developed for practical identifiability analysis in biological models. The framework establishes a rigorous definition, introduces efficient coordinate‐based identifiability metrics, and proposes novel regularization strategies.

Artificial Room‐Temperature Ferromagnetism of Bulk van der Waals VSe2

Advanced Science, EarlyView.
Artificial room‐temperature vdW ferromagnetism of bulk VSe2 has been presented via nano‐crystallization. By constructing the MFM junction with nano‐crystallized VSe2, vdW ferromagnetism has been spatially resolved with a ferromagnetic hysteresis curve.

On a generalized Krasnoselskii fixed point theorem

Open Mathematics
This study concerns a Krasnoselskii-type fixed point theorem for the sum of two operators A,BA,B in a Banach space EE, where BB is a Reich-type contractive mapping and AA is a k-set contractive mapping.
