Attractivity Analysis of Memristor-Based Cellular Neural Networks With Time-Varying Delays [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2014
This paper presents new theoretical results on the invariance and attractivity of memristor-based cellular neural networks (MCNNs) with time-varying delays.

Attractive and In-discrete

Minds and Machines, 2001
Summary: I argue that dynamicism does not provide a convincing alternative to currently available cognitive theories. First, I show that the attractor dynamics of dynamicist models are inadequate for accounting for high-level cognition. Second, I argue that dynamicist arguments for the rejection of computation and representation are unsound in light of

On the global attractivity controversy for a delay model of hematopoiesis [PDF]

open access: yesApplied Mathematics and Computation, 2007
Recently, particular counterexamples were constructed to some theorems of a previous paper, concerning the global attractivity of the positive equilibrium for the delay equation \dot{p}(t) = (beta p(m)(t-tau)/1 + p(n)(t-tau))-gamma p(t).

Finite-time attractivity for semilinear tempered fractional wave equations

Fractional Calculus and Applied Analysis, 2018
We prove the existence and finite-time attractivity of solutions to semilinear tempered fractional wave equations with sectorial operator and superlinear nonlinearity. Our analysis is based on the α-resolvent theory, the fixed point theory for condensing

County-Scale Migration Attractivity and Factors Analysis

GEOINFORMATICS, 2018
To study migration at county scale and measurement of destination attractivity accurately can reveal the migration flows in more details and explain what kinds of county have higher attractivity ability that will help local governors make better policies

Attracting a ride

Nature Reviews Microbiology, 2020
A recent study found that bacterial volatile organic compounds attract springtails to soil-dwelling Streptomyces species, promoting the dispersal of spores.

Facial attractiveness

Trends in Cognitive Sciences, 1999
Humans in societies around the world discriminate between potential mates on the basis of attractiveness in ways that can dramatically affect their lives. From an evolutionary perspective, a reasonable working hypothesis is that the psychological mechanisms underlying attractiveness judgments are adaptations that have evolved in the service of choosing

A simple attraction

Computers & Graphics, 1992
Abstract The computer artist, just as any artist, often looks for sources of new images to incorporate into a work. One source for new images are chaotic attractors. Several computational techniques and graphical results are provided.
