In-Human Multiyear Evolution of Carbapenem-Resistant Klebsiella pneumoniae Causing Chronic Colonization and Intermittent Urinary Tract Infections: A Case Study

open access: yesmSphere, 2022
Carbapenem-resistant Klebsiella pneumoniae (CRKP) is a frequent pathogen of the urinary tract, but how CRKP adapts in vivo over time is unclear. We examined 10 CRKP strains from a patient who experienced chronic colonization and recurrent urinary tract ...

Recurrence Quantification Analysis of the Period-Doubling Sequence [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2018
The period-doubling sequence is one of the most well-known aperiodic [Formula: see text]–[Formula: see text] sequences. In this paper, a complete description of its symbolic recurrence plot is given, and formulas for asymptotic values of basic recurrence quantifiers are derived.

Blocks within the period of Lucas sequence [PDF]

open access: yes, 2021
In this paper, we consider the periodic nature of the sequence of  Lucas numbers L_n defined by the recurrence relation L_n= L_(n-1)+L_(n-2); for all n≥2; with initial condition L_0=2 and L_1=1.

Global Dynamics of Delayed Sigmoid Beverton–Holt Equation

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, certain dynamic scenarios for general competitive maps in the plane are presented and applied to some cases of second-order difference equation xn+1=fxn,xn−1, n=0,1,…, where f is decreasing in the variable xn and increasing in the variable

Spectral pulsations of dissipative solitons in ultrafast fiber lasers: period doubling and beyond

open access: yes, 2022
Period doubling is a universal bifurcation of central importance in all disciplines of nonlinear science, which generally signals the existence of chaotic dynamics in the vicinity of the system parameters.

LONGITUDINAL-FLEXURAL SELF-SUSTAINED VIBRATIONS OF NANOTUBE CONVEYING FLUID

open access: yesEast European Journal of Physics, 2018
Beam model of geometrical nonlinear longitudinal-flexural self-sustained vibrations of nanotube conveying fluid is obtained with account of nonlocal elasticity. The Euler-Bernoulli hypotheses are the basis of this model.

Period doubling solitons: yes or no? [PDF]

open access: yes, 1991
We investigate the possibility of period doubling transition to temporal chaos of a coherent structure in a finite dimensional Hamiltonian system with moderately small friction.

Two-dimensional Dynamic Coupled Mapping Lattice System Based on m-sequence and Spherical Cavity and Its Characteristics [PDF]

open access: yesJisuanji kexue
In order to solve the problems of low dynamic complexity and high correlation between generated sequences in existing spatiotemporal chaotic systems,two-dimensional dynamic coupled map lattices system based on m-sequences and spherical cavity is proposed.

Period-doubling bifurcations and islets of stability in two-degree-of-freedom Hamiltonian systems

open access: yes, 2023
In this paper, we show that the destruction of the main KAM islands in two-degree-of-freedom Hamiltonian systems occurs through a cascade of period-doubling bifurcations.

Analysis, adaptive control and circuit simulation of a novel finance system with dissaving

open access: yesArchives of Control Sciences, 2016
In this paper a novel 3-D nonlinear finance chaotic system consisting of two nonlinearities with negative saving term, which is called ‘dissaving’ is presented. The dynamical analysis of the proposed system confirms its complex dynamic behavior, which is
