The Eyring–Kramers law describes the mean transition time of an overdamped Brownian particle between local minima in a potential landscape. In the weak-noise limit, the transition time is to leading order exponential in the potential difference to overcome. This exponential is corrected by a prefactor which depends on the principal curvatures of the potential at the starting minimum and at the ...

This study examined the effects of cognitive task complexity increase on the complexity, accuracy, and fluency (CAF) as well as the temporal distribution of the cognitive and metacognitive processes involved in computer-mediated L2 written production. To this end, the study employed a between-subjects experimental design with 85 EFL learners from a language learning institute in Iran. Participa...

We present an analysis of early BAT and XRT data for 107 gamma–ray bursts (GRBs) observed by the Swift satellite. We use these data to examine the behaviour of the X-ray light curve and propose a classification scheme for GRBs based on this behaviour. As found for previous smaller samples, the earliest X-ray light curve can be well described by an exponential which relaxes into a power law, oft...

The current study aimed to examine the effects of strategic planning, online planning, strategic planning and online planning combined (joint planning), and no planning on the complexity, accuracy, and fluency of oral productions in two simple and complex narrative tasks. Eighty advanced EFL learners performed one simple narrative task and a complex narrative task with 20 minutes in between. Th...

introduction: in this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. epilepsy is considered as a dynamical change in nonlinear and complex brain system. the ability of the proposed measure for characterizing the normal and epileptic eeg signals when the signal is short or is...

44 played a dominant role in Przymusinski's versions of WFS and ST N. The results of Section 4 underline the very strong relationship of NMR-semantics with nonmonotonic logics. We have also tried (in Section 5) to use another branch of nonmonotonic logics in order to get a classiication of the various diierent semantics: the approach, pioneered by Makinson, Kraus, Lehmann and Magidor, of inspec...

The concept of "pattern" is introduced, formally defined, and used to analyze various measures of the complexity of finite binary sequences and other objects. The standard Kolmogoroff.Chaitin.Solomonoff complexity measure is considered, along with Bennett’s ’logical depth; Koppel’s "sophistication’, and Chaitin’s analysis ofthe complexity of geometric objects. The pattern.theoretic point of vie...

in the first part of the paper we survey some far reaching applications of the basis facts of linear programming to the combinatorial theory of simple polytopes. in the second part we discuss some recent developments concurring the simplex algorithm. we describe sub-exponential randomized pivot roles and upper bounds on the diameter of graphs of polytopes.
