Modelling HIV/AIDS Epidemic among Men Who Have Sex with Men in China

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
A compartmental model with antiviral therapy was proposed to identify the important factors that influence HIV infection among gay men in China and suggest some effective control strategies. We proved that the disease will be eradicated if the reproduction number is less than one.

Process Completing Sequences for Resource Allocation Systems with Synchronization

open access: yesJournal of Control Science and Engineering, Volume 2012, Issue 1, 2012., 2012
This paper considers the problem of establishing live resource allocation in workflows with synchronization stages. Establishing live resource allocation in this class of systems is challenging since deciding whether a given level of resource capacities is sufficient to complete a single process is NP‐complete.

On Conley′s fundamental theorem of dynamical systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 26, Page 1397-1401, 2004., 2004
We generalize Conley′s fundamental theorem of dynamical systems in Conley index theory. We also conclude the existence of a regular index filtration for every Morse decomposition.

Approximate inertial manifolds for nonlinear parabolic equations via steady‐state determining mapping

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 1, Page 1-24, 1995., 1993
For nonlinear parabolic evolution equations, it is proved that, under the assumptions of local Lipschitz continuity of nonlinearity and the dissipativity of semiflows, there exist approximate inertial manifolds (AIM) in the energy space and that the approximate inertial manifolds are constructed as the graph of the steady‐state determining mapping ...

Statistical properties of Lorenz like flows, recent developments and perspectives

open access: yes, 2014
We comment on mathematical results about the statistical behavior of Lorenz equations an its attractor, and more generally to the class of singular hyperbolic systems.

Invariants for E_0-semigroups on II_1 factors [PDF]

open access: yes, 2012
We introduce four new cocycle conjugacy invariants for E_0-semigroups on II_1 factors: a coupling index, a dimension for the gauge group, a super product system and a C*-semiflow.

Nonlocal Cooperative Behavior, Psychological Effects, and Collective Decision‐Making: An Exemplification With Predator–Prey Models

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12011-12037, August 2025.
ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.

Common zeros of inward vector fields on surfaces [PDF]

open access: yes, 2012
A vector field X on a manifold M with possibly nonempty boundary is inward if it generates a unique local semiflow $\Phi^X$. A compact relatively open set K in the zero set of X is a block.

Stability of the global attractor under Markov-Wasserstein noise [PDF]

open access: yes, 2011
We develop a "weak Wa\.zewski principle" for discrete and continuous time dynamical systems on metric spaces having a weaker topology to show that attractors can be continued in a weak sense.

Global attractors for gradient flows in metric spaces [PDF]

open access: yes, 2009
We develop the long-time analysis for gradient flow equations in metric spaces. In particular, we consider two notions of solutions for metric gradient flows, namely energy and generalized solutions.
