A RVR-based Method for Bias Field Estimation in Brain Magnetic Resonance Images Segmentation
A RVR-based Method Bias Field Estimation Brain Magnetic Resonance Images Segmentation
2018/4/19
Abstract— This paper presents a relevance vector regression (RVR) based parametric approach to the bias field estimation in brain magnetic resonance (MR) image segmentation. Segmentation is a very imp...
Nonexistence of formal first integrals for nonlinear systems under resonance
Non-integrability Resonance First integral Normal form
2011/10/12
In this paper, by using normal form theory we give some criteria of nonexistence of formal first integrals for general nonlinear systems under resonance. As application, we also give a criterion for n...
Sequential vibrational resonance in multistable systems
multistable system vibrational resonance signal amplification
2011/7/6
The phenomenon of sequential vibrational resonance existed in a multistable system that is excited by both high- and low-frequency signals is reported. By the method of direct separation of motions, t...
Pseudo resonance induced quasi-periodic behavior in stochastic threshold dynamics
Pseudo resonance quasi-periodic behavior stochastic threshold dynamics
2011/7/5
Here we present a simple stochastic threshold model consisting of a deterministic slowly
decaying term and a fast stochastic noise term. The process shows a pseudo-resonance,
in the sense that for s...
Forced Nonlinear Resonance in a System of Coupled Oscillators
Forced Nonlinear Resonance System of Coupled Oscillators
2011/1/19
We consider a resonantly perturbed system of coupled nonlinear oscillators with small dissipation and outer periodic perturbation. We show that for the large time t ∼ "−2 one component of ...
Strong-field dipole resonance. I. Limiting analytical cases
population dynamics N-level systems dipolar molecules resonance
2011/3/3
We investigate population dynamics in N-level systems driven beyond the linear regime by a
strong external field, which couples to the system through an operator with nonzero diagonal
elements.

Rational surface Line arrangement syzygy
2011/1/18
Conjectures of Suciu [36] relate the fundamental group of an arrangement complement M = Cn \A to the first resonance variety of H(M, Z).We describe a connection between the first resonance variety an...
Asymptotic stability of spin orbit resonance for the dynamics of a viscoelastic satellite
Asymptotic stability spin orbit resonance dynamics viscoelastic satellite
2011/2/25
We prove the asymptotic stability of 1:1 spin orbit resonance for a stiff viscoelastic rotationally invariant satellite. The main point is that we do not assume any dissipation on the orbital degrees ...

We consider a resonantly perturbed system of coupled nonlinear oscillators with small dissipation and outer periodic perturbation. We show that for the large time t ∼ "−2 one component of ...
Decay of Resonance Structure and Trapping Effect in Potential Scattering Problem of Self-Focusing Wave Packet
Quantum Gases (cond-mat.quant-gas) Exactly Solvable and Integrable Systems (nlin.SI)
2010/11/10
Potential scattering problems governed by the time dependent Gross-Pitaevskii equation are investigated numerically for various values of coupling constants. The initial condition is assumed to have t...
Resonance equals reducibility for A-hypergeometric systems
toric hypergeometric Euler–Koszul homology D-module resonant
2010/12/8
Classical Theorems of Gel’fand et al., and recent results of Beuk-ers show essentially that non-confluent A-hypergeometric systems have re-ducible monodromy representation if and only if the continuou...

2010/12/7
This paper is devoted to the study of Lyapunov type inequalities for periodic conservative systems. The main results are derived from a previous analysis which relates the best Lyapunov constants to s...
