Transient Absorption Spectroscopy of Blue Copper Sites in Divergent Protein Folds: Azurin Versus Multicopper Oxidase. [PDF]
ChemphyschemUltrafast pump‐probe spectroscopy of two evolutionarily divergent blue copper proteins reveals distinct low‐frequency ground‐state collective modes (38 cm−1 in SLAC, 29 cm−1 in azurin) generated via impulsive stimulated Raman scattering, potentially reflecting the differences in the rigidity of the surrounding protein scaffold beyond a conserved Cu ...

Speech Neurophysiology in Realistic Contexts: Big Hype or Big Leap? [PDF]
Eur J NeurosciSpeech neurophysiology is moving from controlled listening tasks to dynamic, socially rich interactions, challenging traditional methods. This shift promises deeper insights into how the brain processes and represents speech in real‐world contexts, while introducing new analytical complexities.

On nonoscillatory solutions of a nonlinear differential equation [PDF]
Proceedings of the American Mathematical Society, 1972 Sufficient conditions are given which insure that all nonoscillatory solutions of (p(t)x')'+h(x)x'+q(t)g(x) =f (t) tend to zero as t tends to infinity. In this paper we examine the behavior of the nonoscillatory solutions of the equation (1) (p(t)x')' + h(x)x' + q(t)g(x) = f(t) where p, q, andf are real valued and continuous for t >0 and h and g are ...

Nonoscillatory solutions for discrete equations
Computers & Mathematics with Applications, 2003 The authors consider the discrete equation \[ \Delta(a(k)\Delta(y(k)+ py(k-\tau)))+F(k+1,y(k+1-\sigma))=0 \quad (k\in{\mathbb N}), \] here \(\Delta\) is the difference operator, \(F\) is a continuous map from \({\mathbb N}\times (0,\infty)\) into \([0,\infty), \tau,\sigma\in{\mathbb N}\cup\{0\}, a:{\mathbb N}\to(0,\infty)\), and \(p\in{\mathbb R}\).

Existence of nonoscillatory solutions of a class of nonlinear difference equations with a forced term [PDF]
, 2001 summary:In this paper, necessary and sufficient conditions for the existence of nonoscillatory solutions of the forced nonlinear difference equation \[ \Delta (x_{n}-p_{n} x_{\tau (n)})+f(n,x_{\sigma (n)})=q_{n} \] are obtained.

On unbounded nonoscillatory solutions of systems of neutral differential equations [PDF]
, 1992 summary:In the paper we study the existence of nonoscillatory solutions of the system $x^{(n)}_i(t)=\sum^2_{j=1}p_{ij}(t)f_{ij}(x_j(h_{ij}(t))), n\geq 2, i=1,2$, with the property $lim_{t\rightarrow \infty}x_i(t)/t^{k_i}=const \neq 0$ for some $k_i\in ...

Nonoscillatory solutions for super-linear Emden-Fowler type dynamic equations on time scales
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper, we consider the following Emden-Fowler type dynamic equations on time scales \begin{equation*} \big(a(t)|x^\Delta(t)|^\alpha \operatorname{sgn} x^\Delta(t)\big)^\Delta+b(t)|x(t)|^\beta \operatorname{sgn}x(t)=0, \end{equation*} when ...

An asymptotic formula for solutions of nonoscillatory half-linear differential equations [PDF]
, 2008 summary:We establish a Hartman type asymptotic formula for nonoscillatory solutions of the half-linear second order differential equation \[ \left(r(t)\Phi (y^{\prime })\right)^{\prime }+c(t)\Phi (y)=0\,,\quad \Phi (y):=|y|^{p-2}y\,,\ p>1\,. \

Effect of nonlinear perturbations on second order linear nonoscillatory differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2010 The aim of this paper is to show that any second order nonoscillatory linear differential equation can be converted into an oscillating system by applying a sufficiently large nonlinear perturbation.
