In this paper, we study dense subsets of boundaries of CAT(0) groups. Suppose that a group G acts geometrically on a CAT(0) space X and suppose that there exists an element g0 ∈ G such that (1) Zg0 is finite, (2) X \ Fg0 is not connnected, and (3) each component of X \ Fg0 is convex and not g0-invariant, where Zg0 is the centralizer of g0 and Fg0 is the fixed-point set of g0 in X (that is, Zg0 ...

The quiescent (G0) phase of the cell cycle is the reversible phase from which the cells exit from the cell cycle. Due to the difficulty of defining the G0 phase, quiescent cells have not been well characterized. In this study, a fusion protein consisting of mVenus and a defective mutant of CDK inhibitor, p27 (p27K(-)) was shown to be able to identify and isolate a population of quiescent cells ...

The current model of the animal cell division cycle proposes that the G, phase of the division cycle is the location of most, if not all, of the events regulating the growth and division of animal cells., Fantes2 has reviewed the ideas involved in this current model, and in particular the relationship between the Go phase and the G, period of the division cycle. His point of departure was the w...

BACKGROUND: Cellular senescence is a stress response, triggered by various stimuli such as chemotherapy treatment and causes G0/G1 cell cycle arrest followed the production of associated secretory phenotype. p53 considered to be modulator these events although precise mechanisms it remains not clear.
 AIMS: To determine non-apoptotic functions protein formation phenotype melanoma cells und...

Identifying and locating the geochemical geophysical heterogeneities in Earth’s interior is one of most important challenging tasks for deep Earth scientists. Subducted oceanic crust metamorphizes into dense eclogite upper mantle considered as a major cause Earth. In order to detect eclogitic materials inside Earth, precise measurements high pressure-temperature single-crystal elasticity minera...

The cell cycle of antigen-specific T cells in vivo has been examined by using a few methods, all which possess some limitations. Bromodeoxyuridine (BrdU) marks that are or recently completed S-phase, and carboxyfluorescein succinimidyl ester (CFSE) detects daughter after division. However, these dyes do not allow identification the phase at time analysis. An alternative approach is to exploit K...

A controller for a real-life system G0 is usually designed on the basis of a model Ĝ of G0 identified using data collected from the true system. When designing the identification experiment, the control engineer often has to make a trade-off between her/his desire of obtaining an accurate model and the economical constraint of keeping the experimental costs low. Obtaining an accurate model requ...

For a complex semisimple Lie group G and a real form G0 we define a Poisson structure on the variety of Borel subgroups of G with the property that all G0-orbits in X as well as all Bruhat cells (for a suitable choice of a Borel subgroup of G) are Poisson submanifolds. In particular, we show that every non-empty intersection of a G0-orbit and a Bruhat cell is a regular Poisson manifold, and we ...

where g(t) is a family of Kähler metrics and Ric(ωg) denotes the Ricci curvature of g. It is known that for any smooth Kähler metric g0, there is a unique solution g(t) of (1.1) for some maximal time T > 0 with g(0) = g0. In general, T will depend on the initial metric g0. However, in Kähler manifold, this only depends on the Kähler class and the first Chern class. This observation plays a impo...

We show that the recently developed self-consistent theory of Anderson localization with a positiondependent diffusion coefficient is in quantitative agreement with the supersymmetry approach up to terms of the order of 1 /g0 2 with g0 the dimensionless conductance in the absence of interference effects and with large-scale ab initio simulations of the classical wave transport in disordered wav...
