Global well-posedness, existence of globally absorbing sets and existence of inertial manifolds is investigated for a class of diffusive Burgers equations. The class includes diffusive Burgers equation with nontrivial forcing, the Burgers-Sivashinsky equation and the QuasiStedy equation of cellular flames. The global dissipativity is proven in 2D for periodic boundary conditions. For the proof ...

We study the map 9: C!C defined by 9(w, z)=(z, z+w) and the associated collection of sequences [zj] satisfying the recurrence zj+2=zj+1+zj . Iteration of 9 is equivalent to the study of such sequences. We analyze growth rates of the sequences, positive sequences, periodic and asymptotically periodic sequences and establish the existence of doubly infinite homoclinic sequences, non-zero sequence...

We provide a framework to build periodic boundary conditions on the pseudosphere (or hyperbolic plane), the infinite two-dimensional Riemannian space of constant negative curvature. Starting from the common case of periodic boundary conditions in the Euclidean plane, we introduce all the needed mathematical notions and sketch a classification of periodic boundary conditions on the hyperbolic pl...

A model of flow passing through the glottis is presented by employing the boundary-layer assumption. A thin boundary layer near the glottal wall influences the flow behavior in terms of the flow separation, jet formation, and pressure distribution along the channel. The integral momentum relation has been developed to analyze the boundary layer accurately, and it can be solved numerically for t...

There is a severe lack of instruments to assess problem gambling in Chinese people. This study examined the psychometric properties of the Chinese version of the Maroondah Assessment Profile for Problem Gambling (Chinese G-MAP), based on the responses of eight problem gamblers and 125 pathological gamblers seeking help from a problem gambling treatment center. Reliability analyses showed that t...

Equilibration times for nuclear matter configurations – modelling intermediate and high energy nucleus-nucleus collisions – are evaluated within the semiclassical off-shell transport approach developed recently. The transport equations are solved for a finite box in coordinate space employing periodic boundary conditions. The off-shell transport model is shown to give proper off-shell equilibri...

We derive Bogomolny-type equations for the Abelian Higgs model defined on the noncommutative torus and discuss its vortex like solutions. To this end, we carefully analyze how periodic boundary conditions have to be handled in noncommutative space and discussed how vortex solutions are constructed. We also consider the extension to an U(2)×U(1) model, a simplified prototype of the noncommutativ...

Photodynamic therapy (PDT) is used to treat localized premalignant or early malignant disease. This study reports the enhanced, systemic antitumor immune response from PDT, suggesting that it may have a potential role as a therapy to address both local and disseminated disease.

Let IR 2 be a bounded domain that is smooth except for a nite number of corners. The aim of this paper is to obtain conditions such that the solution of the Poisson problem ?u = f 0 in (f 6 = 0), with zero Dirichlet boundary condition, behaves similarly at the boundary as does the rst eigenfunction 1. That is: there exist c 1 ; c 2 > 0 such that c 1 1 (x) u (x) c 2 1 (x) : As a consequence we c...
