Interaction frequency, network position, and the temporal persistence of interactions in a plant–pollinator network
(Ecological Society of America, 2018-01)
Ecological interactions are highly dynamic in time and space. Previous studies of plant–animal mutualistic networks have shown that the occurrence of interactions varies substantially across years. We analyzed interannual ...
On the dynamic behaviour of a nonlinear system weakly connected to a linear single degree-of-freedom system
(2011-12-01)
This paper discusses the dynamic behaviour of a nonlinear two degree-of-freedom system consisting of a harmonically excited linear oscillator weakly connected to a nonlinear attachment that behaves as a hardening Duffing ...

Energy transfer assisted frequency upconversion in Ho 3+ doped fluoroindate glass
(2002-02-01)
Experimental results are reported which show a strong evidence of energy transfer between Ho 3+ ions in a fluoroindate glass excited by a pulsed laser operating at 640 nm. We identified the origin of the blue and green ...

A new statistical test based on the wavelet cross-spectrum to detect time-frequency dependence between non-stationary signals: Application to the analysis of cortico-muscular interactions
(2011)
The study of the correlations that may exist between neurophysiological signals is at the heart of modern techniques for data analysis in neuroscience. Wavelet coherence is a popular method to construct a time-frequency ...
Effect of soil structure interaction on the dynamic responses of base isolated bridges and comparison to experimental results
(Elsevier Ltd, 2018)
In this paper, the effect of soil structure interaction and base isolation on the dynamic characteristics of an instrumented bridge is examined using transfer functions and measured motions in the frequency domain. A three ...
Tuning the frequencies of the normal modes of a nanopillar oscillator through the magnetostatic interaction
(American Physical Society, 2017)
A detailed analytical and numerical study of the spin wave modes of the free layer of a nanopillar spin torque nano-oscillator (STNO) has been performed as a function of the magnetostatic interaction between the free and ...
Functional differences of low- and high-frequency oscillatory dynamics during illusory border perception
(ELSEVIER, 2010)
Neuronal oscillations are an essential part of several brain processes like perception, memory and attention, but little is known about the simultaneous dynamics of different frequency bands in such processes. Here, we ...
