A bound on chaos [PDF]

open access: yesJournal of High Energy Physics, 2015
We conjecture a sharp bound on the rate of growth of chaos in thermal quantum systems with a large number of degrees of freedom. Chaos can be diagnosed using an out-of-time-order correlation function closely related to the commutator of operators ...

An image encryption method based on chaos system and AES algorithm

open access: yesJournal of Supercomputing, 2019
In this paper, a novel image encryption algorithm is proposed based on the combination of the chaos sequence and the modified AES algorithm. In this method, the encryption key is generated by Arnold chaos sequence.

Chaos-Based Image Encryption: Review, Application, and Challenges

open access: yesMathematics, 2023
Chaos has been one of the most effective cryptographic sources since it was first used in image-encryption algorithms. This paper closely examines the development process of chaos-based image-encryption algorithms from various angles, including symmetric

Addressing a systematic error correcting for free and mixed convection when measuring mean radiant temperature with globe thermometers

open access: yesScientific Reports, 2022
It is widely accepted that most people spend the majority of their lives indoors. Most individuals do not realize that while indoors, roughly half of heat exchange affecting their thermal comfort is in the form of thermal infrared radiation. We show that

Study on the Inherent Complex Features and Chaos Control of IS–LM Fractional-Order Systems

open access: yesEntropy, 2016
Based on the traditional IS–LM economic theory, which shows the relationship between interest rates and output in the goods and services market and the money market in macroeconomic. We established a four-dimensional IS–LM model involving four variables.

The CHAOS-7 geomagnetic field model and observed changes in the South Atlantic Anomaly [PDF]

open access: yesEarth, Planets and Space, 2020
We present the CHAOS-7 model of the time-dependent near-Earth geomagnetic field between 1999 and 2020 based on magnetic field observations collected by the low-Earth orbit satellites Swarm , CryoSat-2, CHAMP, SAC-C and Ørsted, and on annual differences ...

Fuzzy Control of Chaos [PDF]

open access: yes, 1998
We introduce the idea of the fuzzy control of chaos: we show how fuzzy logic can be applied to the control of chaos, and provide an example of fuzzy control used to control chaos in Chua's ...

Complex Dynamics of an Adnascent-Type Game Model

open access: yesDiscrete Dynamics in Nature and Society, 2008
The paper presents a nonlinear discrete game model for two oligopolistic firms whose products are adnascent. (In biology, the term adnascent has only one sense, “growing to or on something else,” e.g., “moss is an adnascent plant.” See Webster's Revised ...

In Extraction and Analysis of Methadone in Exhaled Breath Condensate Using a Validated LC-UV Method; Khoubnasabjafari et al, J Pharm Pharm Sci 18(2) 207-219, 2015, all methadone concentrations should read “µg/mL” rather than “µg/L”.
