On the Superstability of Lobačevskiǐ’s Functional Equations with Involution [PDF]
, 2016 Let G be a uniquely 2-divisible commutative group and let f,g:G→C and σ:G→G be an involution. In this paper, generalizing the superstability of Lobačevskiǐ’s functional equation, we consider f(x+σy)/22-g(x)f(y)≤ψ(x) or ψ(y) for all x,y∈G, where ψ:G→R ...

Extraordinary stability of surfactant‐free bubbles suspended in ultrasound
Droplet, Volume 3, Issue 2, April 2024.In this study, we report that, for the first time, extraordinary stability of liquid bubbles can be obtained from acoustic levitation. The lifetime of bubbles can be prolonged by more than two orders of magnitude owing to the stabilization by the sound field, for instance, a pure water bubble can remain unburst for about 8 min. This suggests the bubble

Approximate *-derivations and approximate quadratic *-derivations on
Journal of Inequalities and Applications, 2011 In this paper, we prove the stability of *-derivations and of quadratic *-derivations on Banach *-algebras. We moreover prove the superstability of *-derivations and of quadratic *-derivations on C*-algebras.

Activation mechanisms and structural dynamics of STIM proteins
The Journal of Physiology, Volume 602, Issue 8, Page 1475-1507, 15 April 2024.Abstract Figure STIM activation involves a series of conformational rearrangements that transform the protein from a quiescent, tight state (left) into an active, extended state (right). While the exact series of events is still unresolved, currently available structural resolutions of STIM represent key pieces in solving the puzzle of STIM activation.

On the Stability of Trigonometric Functional Equations
Advances in Difference Equations, 2008 The aim of this paper is to study the superstability related to the d'Alembert, the Wilson, the sine functional equations for the trigonometric functional equations as follows: f(x+y)−f(x−y)=2f(x)g(y),f(x+y)−f(x−y)=2g(x)f(y).

Carbon Energy, Volume 6, Issue 3, March 2024.We designed Fe(Cd)–CNx catalysts composed of Fe single atoms and adjacent Fe clusters. The interaction between Fe clusters and satellite FeN4 sites drives the catalyst to exhibit ultrahigh ORR activity and durability in acidic and basic media. Zinc–air cells in a liquid or flexible solid state with Fe(Cd)–CNx as the cathode exhibit high power density ...

Ecology, Volume 105, Issue 2, February 2024.Abstract A growing body of literature recognizes that pairwise species interactions are not necessarily an appropriate metaphorical molecule of community ecology. Two examples are intransitive competition and nonlinear higher‐order effects. While these two processes have been discussed extensively, the explicit analysis of how the two of them behave ...

Relative injective modules, superstability and noetherian categories [PDF]
We study classes of modules closed under direct sums, $\mathcal{M}$-submodules and $\mathcal{M}$-epimorphic images where $\mathcal{M}$ is either the class of embeddings, $RD$-embeddings or pure embeddings.

Approximately Ternary Homomorphisms and Derivations on C∗-Ternary Algebras
Abstract and Applied Analysis, 2012 We investigate the stability and superstability of ternary homomorphisms between C*-ternary algebras and derivations on C*-ternary algebras, associated with the following functional equation f((x2-x1)/3)+f((x1-3x3)/3)+f((3x1+3x3-x2)/3)=f(x1).
