How to generate accurate continuous thermal regimes from sparse but regular temperature measurements

open access: yesMethods in Ecology and Evolution, 2023
In ecology, there is an emerging emphasis on the importance of capturing temperature variation at relevant scales. Temperature fluctuates continuously in nature but is sampled at discrete time points, so how often should ecologists measure temperature to

Experimental Observation of Resonance-Assisted Tunneling

open access: yes, 2015
We present the first experimental observation of resonance-assisted tunneling, a wave phenomenon, where regular-to-chaotic tunneling is strongly enhanced by the presence of a classical nonlinear resonance chain. For this we use a microwave cavity made of

含非线性梯度项的椭圆方程大解的渐近行为(Asymptotic behavior of large solution to elliptic problems with nonlinear gradient terms)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2011
By Karamata regular variation theory and the method of lower and supper solution, the boundary behavior of boundary blow-up solutions of the nonlinear elliptic equation Δu± | ▽u|q = b(x) f(u) in Ω,subject to the singular boundary condition u | ∂Ω =+∞ is ...

Translational Regular Variability and the Index Function

open access: yesAxioms
This paper deals with translational regular and rapid variations. By using a new method of proving the Galambos–Bojanić-Seneta type theorems, we prove two theorems of this type for translationally regularly varying and translationally rapidly varying ...

A characterization of multivariate regular variation

open access: yesThe Annals of Applied Probability, 2002
We establish the equivalence between the multivariate regular variation of a random vector and the univariate regular variation of all linear combinations of the components of such a vector.

Methods in half-linear asymptotic theory

open access: yesElectronic Journal of Differential Equations, 2016
We study the asymptotic behavior of eventually positive solutions of the second-order half-linear differential equation $$ (r(t)|y'|^{\alpha-1}\hbox{sgn} y')'=p(t)|y|^{\alpha-1}\hbox{sgn} y, $$ where r(t) and p(t) are positive continuous functions ...
