On Stability and Superstability of Some Generalized Cauchy Functional Equations
, 2014 In this thesis, we study some importants facts on Cauchy functional equations and we study the stability and superstability of some generalized Cauchy functional equations. We study the Hyers-Ulam, Th. M.

Journal of Symbolic Logic, 2005 AbstractIt is proved that all groups of finite U-rank that have the descending chain condition on definable subgroups are totally transcendental. A corollary is that any stable group that is definable in an o-minimal structure is totally transcendental of finite Morley rank.

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

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.

Superstable geometry in triadic percolation
Physical Review ETriadic percolation turns bond percolation into a dynamical problem governed by an effective one-dimensional unimodal map. We show that the geometry of superstable cycles provides a direct, map-agnostic probe of local nonlinearity: specifically, the distance from the map's maximum to a distinguished next-to-maximum point on the ...

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 ...

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).

New insights into suspended drops: When soft matter meets acoustic levitation
Droplet, Volume 3, Issue 1, January 2024.We reviewed the new advances of acoustic levitation as well as the most classic literatures in soft matter field. We focused on the fundamental researches in this field using this technique, and discussed the unique physics/chemical processes involved in the acoustically levitated drops.
