Facial Attractiveness [PDF]

open access: yesWIREs Cognitive Science, 2014
Facial attractiveness has important social consequences. Despite a widespread belief that beauty cannot be defined, in fact, there is considerable agreement across individuals and cultures on what is found attractive. By considering that attraction and mate choice are critical components of evolutionary selection, we can better understand the ...

Uniform weak attractivity and criteria for practical global asymptotic stability [PDF]

open access: yesSystems & control letters (Print), 2017
A subset A of the state space is called uniformly globally weakly attractive if for any neighborhood S of A and any bounded subset B there is a uniform finite time τ so that any trajectory starting in B intersects S within the time not larger than τ . We

Global attractivity in a recursive sequence [PDF]

open access: yes, 2004
In this paper, we Study the invariant intervals, the globally attractivity of the two equilibrium points, and the oscillatory behavior of tile solutions of the difference equation x(n =) ax(n-1) - bx(n-2)/c + x(n-2), n = 1,2,......, where a, b. c > 0. (C)

Functional Integro-Differential Equations with State-Dependent Delay and Non-Instantaneous Impulsions: Existence and Qualitative Results

open access: yesFractal and Fractional, 2022
This paper addresses some existence, attractivity and controllability results for semilinear integrodifferential equations having non-instantaneous impulsions on an infinite interval via resolvent operators in case of neutral and state-dependent delay ...

Local attractivity for integro-differential equations with noncompact semigroups

open access: yesNonautonomous Dynamical Systems, 2020
In this paper, we are devoted to study the existence and local attractivity of solutions for a class of integro-differential equations.Under the situation that the nonlinear term satisfy Carathéodory conditions and a noncompactness measure condition, we ...

Explicit Conditions for Stability of Nonlinear Scalar Delay Impulsive Difference Equation

open access: yesAdvances in Difference Equations, 2010
Sufficient conditions are obtained for the uniform stability and global attractivity of the zero solution of nonlinear scalar delay impulsive difference equation, which extend and improve the known results in the literature.

Ambivalence et complexité des nuits urbaines contemporaines : le cas de Bordeaux

open access: yesBollettino della Società Geografica Italiana, 2019
This article focuses on the night-time in Bordeaux, as a complex and ambivalent space-time. The urban night is a space-time no less complex than the daytime, as we will see with the example of the city of Bordeaux.

Global attractivity of solutions for nonlinear fractional order Riemann-Liouville Volterra-Stieltjes partial integral equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper deals with the existence and the attractivity of solutions of a class of fractional order functional Riemann-Liouville Volterra-Stieltjes partial integral equations. Our results are obtained by using Schauder's fixed point theorem.

Attractive and non-attractive currencies [PDF]

open access: yesJournal of International Money and Finance, 2021
In the foreign exchange market, time-varying transaction costs and interest rates may define the time-varying set of attractive currencies for investors. Our study shows that when the currencies are attractive, they tend to deviate from the uncovered interest rate parity and to comove with the global stochastic discount factor (SDF).
