Discontinuous rate-stiffening in a granular composite modeled after cornstarch and water

open access: yesNature Communications, 2019
Cornstarch and water is a mixture that solidifies under impact. The authors find that ordinary sand behaves in a similar way when coated with a thin layer of viscoelastic polymer, suggesting a potential route for designing materials which respond ...

Collective Memory: Transposing Pavlov’s Experiment to Robot Swarms

open access: yesApplied Sciences, 2021
Remembering information is a fundamental aspect of cognition present in numerous natural systems. It allows adaptation of the behavior as a function of previously encountered situations. For instance, many living organisms use memory to recall if a given

Quantized valley Hall response from local bulk density variations

open access: yesCommunications Physics, 2023
The application of a mechanical strain to a 2D material can create pseudo-magnetic fields and lead to a quantized valley Hall effect. However, measuring valley-resolved effects remains a challenging task due to their inherent fragility and dependence on ...

Jamming Transition: Heptagons, Pentagons, and Discs

open access: yesEPJ Web of Conferences, 2017
The jamming behavior of a system composed of discs has been well documented. However, it remains unclear how a granular system consisting of non-spherical particles transitions between unjammed and jammed states.

Modification of the Logistic Map Using Fuzzy Numbers with Application to Pseudorandom Number Generation and Image Encryption

open access: yesEntropy, 2020
A modification of the classic logistic map is proposed, using fuzzy triangular numbers. The resulting map is analysed through its Lyapunov exponent (LE) and bifurcation diagrams.

Ascertaining when a basin is Wada: the merging method

open access: yesScientific Reports, 2018
Trying to imagine three regions separated by a unique boundary seems a difficult task. However, this is exactly what happens in many dynamical systems showing Wada basins.

Statistical analysis of Lagrangian transport of subtropical waters in the Japan Sea based on AVISO altimetry data [PDF]

open access: yesNonlinear Processes in Geophysics, 2017
Northward near-surface Lagrangian transport of subtropical waters in the Japan Sea frontal zone is simulated and analysed based on altimeter data for the period from 2 January 1993 to 15 June 2015.

Jamming by compressing a system of granular crosses

open access: yesEPJ Web of Conferences, 2017
A disordered stress-free granular packing can be jammed, transformed into a mechanically rigid structure, by increasing the density of particles or by applying shear deformation.
