(SPRINGER-VERLAG BERLIN, 2006)A nonlinear projection method that uses geodesic distances and the neural gas network is proposed. First, the neural gas algorithm is used to obtain codebook vectors, and a connectivity graph is concurrently created by ...

(Elsevier Masson SAS, 2019)© 2018 Elsevier Masson SASIn this article we prove that 2-soliton solutions of the sine-Gordon equation (SG) are orbitally stable in the natural energy space of the problem H1×L2. The solutions that we study are the 2-kink, ...
-
(American Institute of Physics, 2020)We show, for the first time, the explicit form of the nonlinear partial differential equations (PDEs) subject to the correct boundary conditions that have to be satisfied by transport coefficients having a vanishing ...

(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-06-15)We study the travelling wave problem J * u - u - cu' + f(u) = 0 in R, u(-infinity) = 0, u(+infinity) = 1 with an asymmetric kernel J and a monostable nonlinearity. We prove the existence of a minimal speed, and under ...
-
(Elsevier, 2016)We construct codimension 1 surfaces of any dimension that minimize a periodic nonlocal perimeter functional among surfaces that are periodic, cylindrically symmetric and decreasing. These surfaces may be seen as a ...
-
(American Institute of Physics, 2020)A ring resonator made of a silica-based optical fiber is a paradigmatic system for the generation of dissipative localized structures or dissipative solitons. We analyze the effect of the non-instantaneous nonlinear response ...
-
(International Press of Boston, Inc., 2018)The nonlocal s-fractional minimal surface equation for Σ = ∂E where E is an open set in RN is given by HΣ s (p):= RN χE(x) − χEc(x) dx = 0 for all p ∈ Σ. |x − p|N+s Here 0 < s < 1, χ designates characteristic function, ...

(International Press of Boston, 2018-05)The nonlocal s-fractional minimal surface equation for Sigma = partial derivative E where E is an open set in R-N is given by H-Sigma(s)(p) := integral(RN) chi E(x) - chi E-c(x)/vertical bar x - p vertical bar N + s dx ...

(Springer New York LLC, 2019)© 2018, International Association for Mathematical Geosciences.Delineation of facies in the subsurface and quantification of uncertainty in their boundaries are significant steps in mineral resource evaluation and reservoir ...
-
(1990)Nonrelativistic full-folding optical model potentials for nucleon elastic scattering have been calculated and applied to proton scattering on ' 0 and Ca at energies between 135 and 500 MeV. The optical potentials were ...
-
(SAGE Publications Inc., 2019)© International & American Associations for Dental Research 2018.The goal of nonrestorative or non- and microinvasive caries treatment (fluoride- and nonfluoride-based interventions) is to manage the caries disease process ...
-
(Springer, 2016)In this paper, we study the well-posedness and stability analysis of set-valued Lur'e dynamical systems in infinite-dimensional Hilbert spaces. The existence and uniqueness results are established under the so-called ...
-
(Springer, 2016)The general theory of Lyapunov stability of first-order differential inclusions in Hilbert spaces has been studied by the authors in the previous paper (Adly et al. in Nonlinear Anal 75(3): 985-1008, 2012). This new ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-02)The main objective of this paper is to provide new explicit criteria to characterize weak lower semicontinuous Lyapunov pairs or functions associated to first-order differential inclusions in Hilbert spaces. These inclusions ...
-
(Universidad de Chile, 2021)In several disciplines, Gaussian Processes (GPs)\cite{williams2006gaussian} are the gold standard for modelling time series or functions in general, especially in cases where modelling uncertainty is required. The extension ...
-
(Wiley, 2015)For the abelian self-dual Chern-Simons-Higgs model we address existence issues of periodic vortex configurations—the so-called condensates—of nontopological type as k ! 0, where k > 0 is the Chern-Simons parameter. We ...
-
(American Physical Society, 2017)Multistable systems exhibit a rich front dynamics between equilibria. In one-dimensional scalar gradient systems, the spread of the fronts is proportional to the energy difference between equilibria. Fronts spreading p ...

(ELSEVIER, 2006-08-21)We consider the representable equational theory of binary relations, in a language expressing composition, converse, and lattice operations. By working directly with a presentation of relation expressions as graphs we are ...
