A fixed-point theorem of Krasnoselskii
Applied Mathematics Letters, 1998 Krasnosel'skij's fixed-point theorem asks for a convex set \(M\) and a mapping \(Pz=Bz+Az\) such that (i) \(Bx+Ay\in M\) for each \(x,y\in M\), (ii) \(A\) is continuous and compact, (iii) \(B\) is a contraction. Then \(P\) has a fixed point. A careful reading of the proof reveals that (i) need only ask that \(Bx+Ay\in M\) when \(x=Bx+Ay\).

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 ...

The Existence of Cone Critical Point and Common Fixed Point with Applications
Journal of Applied Mathematics, 2011 We first establish some new critical point theorems for nonlinear dynamical systems in cone metric spaces or usual metric spaces, and then we present some applications to generalizations of Dancš-Hegedüs-Medvegyev's principle and the existence theorem ...

Advanced Science, EarlyView.Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

Minimax and fixed point theorems
Mathematische Annalen, 1980 Since then, numerous applications of this interesting theorem have been found. The object of this note is to obtain a generalization of Theorem 1 by relaxing, among the others, the compactness condition. It contains a fixed point theorem for maps with inwardness or outwardness conditions given by Fan [6]. As its direct consequence, we also obtain a new

Advanced Science, EarlyView.Serine grafted silica coated nanoscale zero‐valent iron is synthesized. Through the SiO2 coating and serine grafting, the aggregation and oxidation of nZVI are reduced, and the slow release of Fe2+ ensured the catalytic cycle. The adsorption capacity for TBP and n‐dodecane is higher, because of the synergistic effect of surface functional groups.
