Free-discontinuity problems generated by singular perturbation [PDF]

open access: yes, 1998
We show that some free discontinuity problems can be obtained as a limit of nonconvex local functionals with a singular perturbation of higher order.

A Singular Tempered Sub-Diffusion Fractional Equation with Changing-Sign Perturbation

open access: yesAxioms
In this paper, we establish some new results on the existence of positive solutions for a singular tempered sub-diffusion fractional equation involving a changing-sign perturbation and a lower-order sub-diffusion term of the unknown function.

Highlighting Link Prediction in Bipartite Networks via Structural Perturbation

open access: yesIEEE Access, 2018
Most of the link prediction algorithms for bipartite networks assume that the generation of link is based on a predefined prior assumption. However, for the real-world bipartite networks, the generation mechanism of link is still ambiguous due to their ...

Singular perturbation for nonlinear boundary-value problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
Asymptotic solutions of a class of nonlinear boundary-value problems are studied. The problem is a model arising in nuclear energy distribution. For large values of the parameter, the differential equations are of the singular-perturbation type and ...

Optical soliton perturbation in parabolic law medium having weak non-local nonlinearity by a couple of strategic integration architectures

open access: yesResults in Physics, 2019
In this paper, the governing model with the inclusion of parabolic law nonlinearity, weakly non-local nonlinearity in addition to perturbation terms is examined for the sake of uncovering quite important optical soliton solutions.

A brief note on the generalized singular perturbation approximation [PDF]

open access: yes, 2015
The generalized singular perturbation approximation is a method for approximation of dynamical systems which has been presented in the literature on model reduction over the past two decades.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Approximate solution to a hybrid model with stochastic volatility: a singular-perturbation strategy [PDF]

open access: yes, 2009
We study a hybrid model of Schobel-Zhu-Hull-White-type from a singular-perturbation-analysis perspective. The merit of the paper is twofold: On one hand, we find boundary conditions for the deterministic non-linear degenerate parabolic partial ...

Entanglement entropy of singular surfaces under relevant deformations in holography

open access: yesJournal of High Energy Physics, 2018
In the vacuum state of a CFT, the entanglement entropy of singular surfaces contains a logarithmic universal term which is only due to the singularity of the entangling surface.
