Impulsive control functional differential systems of fractional order: stability with respect to manifoldsThe European Physical Journal Special Topics - Tập 226 - Trang 3591-3607 - 2018
Martin Bohner, Ivanka Stamova, Gani Stamov
In this paper, we consider nonlinear impulsive functional differential systems involving Caputo fractional derivatives. Using vector multivariable piecewise continuous Lyapunov functions and a new vector fractional comparison principle, stability criteria with respect to a manifold are established. Some examples are presented in order to illustrate our theoretical findings.

Avoiding traps in trajectory space: Metadynamics enhanced transition path samplingThe European Physical Journal Special Topics - Tập 225 - Trang 1609-1620 - 2016
E.E. Borrero, C. Dellago
We propose a transition path sampling (TPS) scheme designed to enhance sampling in systems with multiple reaction channels. In this method, based on a combination of the metadynamics algorithm with the TPS shooting move, a history dependent bias drives the simulation towards unexplored reaction channels. The bias, constructed as a superposition of repulsive Gaussian potentials deposited on the tra...... hiện toàn bộ
The “island of inversion" from a nuclear moments perspective and the g factor of 35SiThe European Physical Journal Special Topics - Tập 150 - Trang 149-153 - 2007
G. Neyens, P. Himpe, D. L. Balabanski, P. Morel, L. Perrot, M. De Rydt, I. Stefan, C. Stodel, J. C. Thomas, N. Vermeulen, D. T. Yordanov
This paper reviews recent results from electromagnetic
moment measurements on isotopes in the island of inversion around
N=20. The obtained moments on neutron rich Na, Mg, Al and Si
isotopes allow to draw conclusions on the amount of intruder
components in their ground state wave function, demonstrating a
gradual transition from the normal sd-shell region into the
island of inversion, starting at ...... hiện toàn bộ
Structure of nuclei far from the stability in relativistic approachThe European Physical Journal Special Topics - Tập 150 - Trang 139-144 - 2007
S. F. Ban, L. S. Geng, W. H. Long, J. Meng, J. Peng, J. M. Yao, S. Q. Zhang, S. G. Zhou
The recent progress of the relativistic many-body approach
by the group at Peking University will be reviewed. In particular,
axially deformed relativistic Hartree-Bogoliubov approach in
Woods-Saxon basis aiming at halo nucleus, time-odd triaxial RMF
approach, the adiabatic and configuration-fixed constrained triaxial
RMF approaches, a Reflection ASymmetric RMF (RAS-RMF) approach, and
a new relati...... hiện toàn bộ
Generators of quasiperiodic oscillations with three-dimensional phase spaceThe European Physical Journal Special Topics - - 2013
A.P. Kuznetsov, S.P. Kuznetsov, E. Mosekilde, N.V. Stankevich
Considering a family of three-dimensional oscillators originating in the field of radio-engineering, the paper describes three different mechanisms of torus formation. Particular emphasis is paid to a process in which a saddle-node bifurcation eliminates a stable cycle and leaves the system to find a stationary state between a saddle cycle and a pair of equilibrium points of unstable focus/stable...... hiện toàn bộ
