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 ...

A Nonoscillatory Second-Order Time-Stepping Procedure for Reaction-Diffusion Equations
Complexity, 2020 After a theory of morphogenesis in chemical cells was introduced in the 1950s, much attention had been devoted to the numerical solution of reaction-diffusion (RD) partial differential equations (PDEs).

Oscillations of equations caused by several deviating arguments [PDF]
Opuscula Mathematica, 2019 Linear delay or advanced differential equations with variable coefficients and several not necessarily monotone arguments are considered, and some new oscillation criteria are given.

Remarks on the existence of nonoscillatory solutions of half-linear ordinary differential equations, I [PDF]
Opuscula Mathematica, 2021 We consider the half-linear differential equation of the form \[(p(t)|x'|^{\alpha}\mathrm{sgn} x')' + q(t)|x|^{\alpha}\mathrm{sgn} x = 0, \quad t\geq t_{0},\] under the assumption \(\int_{t_{0}}^{\infty}p(s)^{-1/\alpha}ds =\infty\). It is shown that if a

Oscillation of deviating differential equations [PDF]
Mathematica Bohemica, 2020 Consider the first-order linear delay (advanced) differential equation x'(t)+p(t)x( \tau(t)) =0\quad(x'(t)-q(t)x(\sigma(t)) =0),\quad t\geq t_0, where $p$ $(q)$ is a continuous function of nonnegative real numbers and the argument $\tau(t)$ $(\sigma(

Oscillation and non-oscillation of some neutral differential equations of odd order
International Journal of Mathematics and Mathematical Sciences, 1992 An existence criterion for nonoscillatory solution for an odd order neutral differential equation is provided. Some sufficient conditions are also given for the oscillation of solutions of some nth order equations with nonlinearity in the neutral term.

Principal solution of half-linear differential equation: Limit and integral characterization
Electronic Journal of Qualitative Theory of Differential Equations, 2008 We investigate integral and limit characterizations of the principal solution of the nonoscillatory half-linear differential equation $$ (r(t)\Phi(x'))'+c(t)\Phi(x)=0,\quad \Phi(x)=|x|^{p-2},\ p>1 $$.

Oscillation criteria for third order nonlinear delay differential equations with damping [PDF]
Opuscula Mathematica, 2015 This note is concerned with the oscillation of third order nonlinear delay differential equations of the form \[\label{*} \left( r_{2}(t)\left( r_{1}(t)y^{\prime}(t)\right)^{\prime}\right)^{\prime}+p(t)y^{\prime}(t)+q(t)f(y(g(t)))=0.\tag{\(\ast\)}\] In ...

Psychiatry and Clinical Neurosciences, EarlyView.Aperiodic electroencephalographic activity is proposed as a scalable marker of cortical population dynamics relevant to excitation–inhibition balance. However, it remains unclear whether aperiodic parameters represent disorder‐specific abnormalities or context‐sensitive indices of clinically relevant brain states.
