The Oscillatory Behavior of a First Order Non-Linear Differential Equation with Delay
, 1974 SynopsisThis paper establishes the existence of an infinite set of zeros for the solution of a certain functional differential equation. The primary condition assuring this oscillatory behavior is expressed in terms of the magnitude of the delay.

Oscillatory and Asymptotic Behavior of a Discrete Logistic Model
Rocky Mountain Journal of Mathematics, 1995 The author considers the discrete logistic model with or without delay \(x_{n + 1} = \alpha_n x_n/(1 + \beta_n x_{n - j})\), for \(n = 0,1,2, \dots\), and \(j \geq 0\), where \(\alpha_n\) and \(\beta_n\) are positive bounded sequences. The oscillatory and asymptotic behavior is completely discussed in the case without delay, this is \(j = 0\).

Oscillatory behavior of three dimensional α-fractional delay differential systems
, 2018 In the present work we study the oscillatory behavior of three dimensional α-fractional nonlinear delay differential system. We establish some sufficient conditions that will ensure all solutions are either oscillatory or converges to zero, by using the ...

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5
Advanced Functional Materials, EarlyView.We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

Advanced Functional Materials, EarlyView.A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation
Advanced Functional Materials, EarlyView.Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...
