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.

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”.

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.

Projective Synchronization of N-Dimensional Chaotic Fractional-Order Systems via Linear State Error Feedback Control

open access: yesDiscrete Dynamics in Nature and Society, 2012
Based on linear feedback control technique, a projective synchronization scheme of N-dimensional chaotic fractional-order systems is proposed, which consists of master and slave fractional-order financial systems coupled by linear state error variables ...

Neimark-Sacker Bifurcation in a Discrete-Time Financial System

open access: yesDiscrete Dynamics in Nature and Society, 2010
A discrete-time financial system is proposed by using forward Euler scheme. Based on explicit Neimark-Sacker bifurcation (also called Hopf bifurcation for map) criterion, normal form method and center manifold theory, the system's existence, stability ...

Bubble Relaxation Dynamics in Homopolymer DNA Sequences

open access: yesMolecules, 2023
Understanding the inherent timescales of large bubbles in DNA is critical to a thorough comprehension of its physicochemical characteristics, as well as their potential role on helix opening and biological function.
