A Dynamic Interactive Approach to Music Listening: The Role of Entrainment, Attunement and Resonance

open access: yesMultimodal Technologies and Interaction, 2023
This paper takes a dynamic interactive stance to music listening. It revolves around the focal concept of entrainment as an operational tool for the description of fine-grained dynamics between the music as an entraining stimulus and the listener as an ...

Considering the Case for Biodiversity Cycles: Reexamining the Evidence for Periodicity in the Fossil Record [PDF]

open access: yes, 2007
Medvedev and Melott (2007) have suggested that periodicity in fossil biodiversity may be induced by cosmic rays which vary as the Solar System oscillates normal to the galactic disk.

$R_0$ and the global behavior of an age-structured SIS epidemic model with periodicity and vertical transmission

open access: yesMathematical Biosciences and Engineering, 2014
In this paper, we study an age-structured SIS epidemic model with periodicity and vertical transmission. We show that the spectral radius of the Fréchet derivative of a nonlinear integral operator plays the role of a threshold value for the global ...

Changes in Flood Regime of the Upper Yangtze River

open access: yesFrontiers in Earth Science, 2021
River flooding affects more people worldwide than other natural hazards. Thus, analysis of the changes in flood regime caused by global warming and increasing anthropogenic activities will help us make adaptive plans for future flood management.

Analytical and Solutions of Fourth Order Difference Equations

open access: yesCommunications in Advanced Mathematical Sciences, 2019
In this article, we presented the solutions of the following recursive sequences\[ x_{n+1}=\frac{x_{n-2}x_{n-3}}{x_{n}(\pm1\pm x_{n-2}x_{n-3})}, \] where the initial conditions $x_{-3}\ ,x_{-2}\ ,x_{-1}$\ and $x_{0}\ $are arbitrary real numbers. Also, we
