Spontaneous Traveling Cortical Waves Gate Perception in Behaving Primates

open access: yesNature, 2020
Perceptual sensitivity varies from moment to moment. One potential source of this variability is spontaneous fluctuations in cortical activity that can travel as waves1. Spontaneous travelling waves have been reported during anaesthesia2–7, but it is not

Traveling waves for nonlocal models of traffic flow [PDF]

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2018
We consider several nonlocal models for traffic flow, including both microscopic ODE models and macroscopic PDE models. The ODE models describe the movement of individual cars, where each driver adjusts the speed according to the road condition over an ...

Simulations approaching data: cortical slow waves in inferred models of the whole hemisphere of mouse [PDF]

open access: yesCommunications Biology, 2021
The development of novel techniques to record wide-field brain activity enables estimation of data-driven models from thousands of recording channels and hence across large regions of cortex.

Traveling waves of selective sweeps [PDF]

open access: yes, 2011
The goal of cancer genome sequencing projects is to determine the genetic alterations that cause common cancers. Many malignancies arise during the clonal expansion of a benign tumor which motivates the study of recurrent selective sweeps in an ...

The Hidden Spatial Dimension of Alpha: 10-Hz Perceptual Echoes Propagate as Periodic Traveling Waves in the Human Brain

open access: yesCell Reports, 2019
Summary EEG reverse-correlation techniques have revealed that visual information processing entails a ∼10-Hz (alpha) occipital response that reverberates sensory inputs up to 1 s.

Traveling waves in integro-difference equations with a shifting habitat

open access: yes, 2020
We study an integro-difference equation that describes the spatial dynamics of a species in a shifting habitat. The growth function is nondecreasing in density and space for a given time, and shifts at a constant speed c.

Bounded and unbounded traveling wave solutions of the (3+1)-dimensional Jimbo-Miwa equation

open access: yesResults in Physics, 2019
This paper studies traveling waves of the (3+1)-dimensional Jimbo-Miwa equation comprehensively and systematically. By transforming its traveling wave system into a dynamical system in R3, we apply the bifurcation method of dynamical system to ...

Simulated holographic three-dimensional intensity shaping of evanescent-wave fields [PDF]

open access: yes, 2008
The size of bright structures in traveling-wave light fields is limited by diffraction. This in turn limits a number of technologies, for example, optical trapping.

Exponential stability of traveling waves for a nonlocal dispersal SIR model with delay

open access: yesOpen Mathematics, 2022
This article is concerned with the nonlinear stability of traveling waves of a delayed susceptible-infective-removed (SIR) epidemic model with nonlocal dispersal, which can be seen as a continuity work of Li et al.

Amplification and Suppression of Traveling Waves along the Mouse Organ of Corti: Evidence for Spatial Variation in the Longitudinal Coupling of Outer Hair Cell-Generated Forces

open access: yesJournal of Neuroscience, 2019
Mammalian hearing sensitivity and frequency selectivity depend on a mechanical amplification process mediated by outer hair cells (OHCs). OHCs are situated within the organ of Corti atop the basilar membrane (BM), which supports sound-evoked traveling ...
