The various forms of psoriasis demonstrate multidirectional changes of the expression of markers of lymphocyte positive and negative activation. Study of activation markers allow identifying different lymphocyte subpopulations, establishing their role in development and progressing of psoriasis as they characterize connected with cellular cycle processes of activation (CD25) and apoptosis (CD95...

In this paper, the new concept of near PS-compactness in L-topological spaces is introduced. It is defined for any L-subset. Its characterizations and topological properties are systematically studied. And the relationship is exposed between near PScompactness and PS-compactness, and also fuzzy compactness. 2003 Elsevier Inc. All rights reserved.

Let A be a nite set of integers. For h 1, let S h (A) denote the set of all sums of h distinct elements of A. Let S(A) denote the set of all nonempty sums of distinct elements of A. The direct problem for subset sums is to nd lower bounds for jS h (A)j and jS(A)j in terms of jAj. The inverse problem for subset sums is to determine the structure of the extremal sets A of integers for which jS h ...

The self-renewal characteristics of stem cells render them vital engines of development. To better understand the molecular mechanisms that determine the properties of stem cells, transcript profiling was conducted on quiescent center (QC) cells from the Arabidopsis thaliana root meristem. The AGAMOUS-LIKE 42 (AGL42) gene, which encodes a MADS box transcription factor whose expression is enrich...

We prove that a singular-hyperbolic (or Lorenz-like) attractor of a 3-dimensional flow is chaotic, in two strong different senses. Firstly, the flow is expansive: if two points remain close for all times, possibly with time reparametrization, then their orbits coincide. Secondly, there exists a physical (or Sinai-Ruelle-Bowen) measure supported on the attractor whose ergodic basin covers a full...

The hydrogen activities described below represent a subset of a larger FWP (ERKCC01) identified above. That effort couples synthesis, advanced characterization (including neutron scattering) and computational and theoretical modeling. The primary objective is to discover and exploit controlled synthetic methods to produce, characterize and ultimately control novel inorganic nanometer-scale mate...

This paper focuses on the relationship between an $L$-subset and the system of level-elements induced by it, where the underlying lattice $L$ is a complete residuated lattice and the domain set of $L$-subset is an $L$-partially ordered set $(X,P)$. Firstly, we obtain the sufficient and necessary condition that an $L$-subset is represented by its system of level-elements. Then, a new representat...

The aim of this paper is the study center-focus and cyclicity problems inside class $$\mathfrak {X}$$ 3-dimensional vector fields that admit a first integral leaves invariant any sphere centered at origin. We classify centers linear, quadratic homogeneous family $$\mathcal {F}\subset \mathfrak , restricted to one these spheres. Moreover, we show existence least 4 limit cycles in {F}$$ .

background: the study was developed in order to find a subset of potential factors, which affect birth distance pattern, regarding consideration on correlation of events of birth in a family and correlation within clusters/centers which other studies omit these correlations. methods: referring to documents that were registered for family in the health care centers on socio-economical zone, we c...
