Thermodynamic properties of the parabolic-well fluid
(Frontiers Media S.A., 2021)
The thermodynamic properties of the parabolic-well fluid are considered. The intermolecular interaction potential of this model, which belongs to the class of the so-called van Hove potentials, shares with the square-well ...

The Lotka-Volterra models with non-local reaction terms
(American Institute of Mathematical Sciences (AIMS), 2022-11)
In this paper we consider a diffusive Lotka-Volterra system including nonlocal terms in the reaction functions. We analyze the main types of interactions between species: competition, predator-prey and cooperation. We ...

Designing robust rapid transit networks with alternative routes
(Hindawi, 2011-01)
The aim of this paper is to propose a model for the design of a robust rapid transit network. In this paper, a network is said to be robust when the effect of disruption on total trip coverage is minimized. The proposed model ...

A multiple focus-center-cycle bifurcation in 4D discontinuous piecewise linear memristor oscillators
(Springer, 2018-12)
The dynamical richness of 4D memristor oscillators has been recently studied in several works, showing different regimes, from stable oscillations to chaos. Typically, only numerical simulations have been reported and so ...

Comment on "A new approach of cooperative interval games: The interval core and Shapley value revisited"
(Elsevier, 2018-07)
The interval Shapley-like value for cooperative interval games was introduced by Han et al. (2012).A theorem of characterization of the interval Shapley-like value was provided in that paper. We show that there is an error ...

Filling and wetting transitions on sinusoidal substrates: a mean-field study of the Landau-Ginzburg model
(IOP Publishing, 2014)
We study the interfacial phenomenology of a fluid in contact with a one-dimensional array of infinitely long grooves of sinusoidal section, characterized by the periodicity length L and amplitude A. The system is modelled ...

Quasi-similarity of contractions having 2 x 2 a singular characteristic function
(Elsevier, 2008)
LetT1:H1→H1be a completely non-unitary contraction having a 2×2 singular characteristic function Θ1; thatis, Θ1=[θi,j]i, j=1,2withθij∈H∞and det(Θ1)=0. Asit is well known, Θ1is a singular matrix if and only ifΘ1can be written ...

Volterra operators and semigroups in weighted Banach spaces of analytic functions
(Springer Open Choice, 2014)
We characterize the boundedness, compactness and weak compactness of Volterra operators Vg( f )(z) := z 0 f (ζ )g (ζ ) dζ acting between different weighted spaces of type H∞ v in terms of the symbol function g, ...

Node aggregation for enhancing PageRank
(IEEE-Institute of Electrical and Electronics Engineers, 2017)
In this paper, we study the problem of node aggregation under different perspectives for increasing PageRank of some nodes of interest. PageRank is one of the parameters used by the search engine Google to determine the ...
