A Continuous-Time Random Walk Extension of the Gillis Model

open access: yesEntropy, 2020
We consider a continuous-time random walk which is the generalization, by means of the introduction of waiting periods on sites, of the one-dimensional non-homogeneous random walk with a position-dependent drift known in the mathematical literature as ...

A new method to reduce the number of time delays in a network

open access: yesScientific Reports, 2017
Time delays may cause dramatic changes to the dynamics of interacting oscillators. Coupled networks of interacting dynamical systems can have unexpected behaviours when the signal between the vertices are time delayed.

Pump–probe x-ray microscopy of photo-induced magnetization dynamics at MHz repetition rates

open access: yesStructural Dynamics, 2023
We present time-resolved scanning x-ray microscopy measurements with picosecond photo-excitation via a tailored infrared pump laser at a scanning transmission x-ray microscope.

A Simple Chaotic Wien Bridge Oscillator with a Fractional-Order Memristor and Its Combination Synchronization for Efficient Antiattack Capability

open access: yesComplexity, 2021
Memristor-based oscillators are of recent interest, and hence, in this paper, we introduce a new Wien bridge oscillator with a fractional-order memristor.

Vibrational Collapse of Hexapod Packings

open access: yesEPJ Web of Conferences, 2017
Columns made of convex noncohesive grains like sand collapse after being released from a confining container. However, structures built from non-convex grains can be stable without external support.

Predicting reading ability from brain anatomy and function: From areas to connections

open access: yesNeuroImage, 2020
Reading is a complex task involving different brain areas. As a crystallized ability, reading is also known to have effects on brain structure and function development.

Impact of Surface Roughness on Crystal Nucleation

open access: yesCrystals, 2020
We examine the effect of rough surfaces on crystal nucleation by means of kinetic Monte Carlo simulations. Our work makes use of three-dimensional kMC models, explicit representation of transport in solution and rough surfaces modeled as randomly varying

Network Dynamics of a Fractional-Order Phase-Locked Loop with Infinite Coexisting Attractors

open access: yesComplexity, 2020
We have investigated a fractional-order phase-locked loop characterised by a third-order differential equation. The integer-order mathematical model of the phase-locked loop (PLL) is first converted to fractional order using the Caputo-Fabrizio method ...

Effect of the land area elevation on the collective choice in ants

open access: yesScientific Reports, 2017
Collective decisions regarding food source exploitation in social insects are influenced by a range of parameters, from source quality to individual preference and social information sharing.
