A model for ac-driven systems, based on the Tang-Wiesenfeld-Bak-Coppersmith-Littlewood automaton for an elastic medium, exhibits mode-locked steps with frequencies that are irrational multiples of the drive frequency, when the pinning is spatially quasiperiodic. Detailed numerical evidence is presented for the large-system-size convergence of such a mode-locked step. The irrational mode locking...

An interesting class of fractal sequences consists of signature sequences for irrational numbers. The signature sequence of the irrational number x is obtained by putting the numbers i + j × x i , j = 1, 2, 3, … in increasing order. Then the values of i for these numbers form the signature sequence for x, which is denoted by S(x). Here's the signature sequence for φ, the golden mean: Both upper...

We study the occurrence of physically observable phase locked states between chaotic oscillators and rotors in which the frequencies of the coupled systems are irrationally related. For two chaotic oscillators, the phenomenon occurs as a result of a coupling term which breaks the 2 pi invariance in the phase equations. In the case of rotors, a coupling term in the angular velocities results in ...

Jonathan St. B. T. Evans, in his engaging article “Rationality and the illusion of choice” (Evans, 2014) argues that erroneous answers to questions posed in the study of reasoning and decision-making (RDM) ought not be viewed as irrational, just as errors in other cognitive domains are not viewed as irrational. He attributes misuse of the term partly to use of normative models borrowed from eco...

Rorschach protocols from 35 children and adolescents with posttraumatic stress disorder (PTSD) and 35 with oppositional defiant disorder (ODD) were compared. Both groups revealed significant differences from the normative tables on the same 12 variables: SCZI, DEPI, CDI, X + %, EgoC, Afr, T, EA, P, WSumC, RawSumSS, and WgtSumSS. However, as predicted, 4 of those variables, the Schizophrenic Ind...

Milton Friedman argued that irrational traders will consistently lose money, won’t survive and, therefore, cannot influence long run equilibrium asset prices. Since his work, survival and price influence have been assumed to be the same. Often partial equilibrium analysis has been relied upon to examine the survival of irrational traders and to make inferences on their influence on prices. In t...

The idea that technological revolutions can explain major swings in stock market value is occupying an increasingly prominent role in the literature on the economics of financial markets. Both the 1990s and the 1920s stock market runups have been linked to the arrival of new technologies and the accumulation of intangible capital by firms (Robert Hall 2001; Bart Hobijn and Boyan Jovanovic 2001;...

BACKGROUND Irrational use of medicines has been an issue concerned all over the world and the outlooks in developing countries are more severe. This study aimed to assess the different patterns of irrational use of medicines and its influential factors in China and Vietnam. METHODS A systematic review was performed on both published and grey literatures in English, Chinese and Vietnamese lang...

Introduction: Considering the importance of the family institution and that marital satisfaction plays the most important role in sustainability of marital life, this study aimed to investigate the mediating role of irrational beliefs in the relationship between family relationship quality and marital satisfaction. Material and Methods: It was a correlation exploratory research. The statistical...
