A simple mathematical model for Batesian mimicry

open access: yesDiscrete Dynamics in Nature and Society, 2005
A simple mathematical model is presented for Batesian mimicry, which occurs when a harmless species (mimic) is morphologically similar to another species (model) that is noxious or distasteful to predators, thus gaining a measure of protection.

Intrinsic electronic noise strength significantly alters a period doubling cascade to chaos

open access: yes, 2021
For universality in the approach, it is customary to appropriately rescale problems to a single or a set of dimensionless equations with dimensionless quantities involved or to rescale the experimental setup to a suitable size for the laboratory ...

Time Quasilattices in Dissipative Dynamical Systems

open access: yesSciPost Physics, 2018
We establish the existence of 'time quasilattices' as stable trajectories in dissipative dynamical systems. These tilings of the time axis, with two unit cells of different durations, can be generated as cuts through a periodic lattice spanned by two ...

Effective suppression of period-doubling in two diffusively coupled logistic maps [PDF]

open access: yes, 1986
We consider a system of two delay diffusively coupled logistic maps. We find that for moderate values of diffusion coupling, the period-doubling sequence is effectively suppressed.

Bounds on the unstable eigenvalue for the asymmetric renormalization operator for period doubling

open access: yes, 2004
We establish rigorous bounds for the unstable eigenvalue of the period-doubling renormalization operator for asymmetric unimodal maps. Herglotz-function techniques and cone invariance ideas are used.

Effects of Doubling the Standard Space Allowance on Behavioural and Physiological Responses of Sheep Experiencing Regular and Irregular Floor Motion during Simulated Sea Transport

open access: yesAnimals, 2020
Transporting livestock at high stocking density by ship presents significant risks to their welfare, especially if it is over long distances. Previous research has investigated small variations in density for long periods or a moderate variation for ...

The evolutionary selective advantage of HIV-1 escape variants and the contribution of escape to the HLA-associated risk of AIDS progression.

open access: yesPLoS ONE, 2008
HIV-1 escape from surveillance by cytotoxic T lymphocytes (CTL) is thought to cause at least transient weakening of immune control. However, the CTL response is highly adaptable and the long-term consequences of viral escape are not fully understood. The

Nonlinear semiclassical dynamics of the unbalanced, open Dicke model

open access: yesPhysical Review Research, 2020
In recent years there have been significant advances in the study of many-body interactions between atoms and light confined to optical cavities. One model that has received widespread attention of late is the Dicke model, which under certain conditions ...

Envelope Words and Return Words Sequences in the Period-doubling Sequence

open access: yes, 2016
We consider the infinite one-sided sequence generated by the period-doubling substitution $σ(a,b)=(ab,aa)$, denoted by $\mathbb{D}$. Since $\mathbb{D}$ is uniformly recurrent, each factor $ω$ appears infinite many times in the sequence, which is arranged as $ω_p$ $(p\ge 1)$. Let $r_p(ω)$ be the $p$-th return word over $ω$.

Period-doubling bifurcations of the thermocapillary convection in a floating half zone

open access: yes, 2010
This study experimentally explored the fine structures of the successive period-doubling bifurcations of the time-dependent thermocapillary convection in a floating half zone of 10 cSt silicone oil with the diameter d (0)=3.00 mm and the aspect ratio A=l/
