in this paper, a certain new connectedness of l-fuzzy subsets inl-topological spaces is introduced and studied by means of preclosed sets. itpreserves some fundamental properties of connected set in general topology.especially the famous k. fan’s theorem holds.

Endothelial dysfunction and chronic inflammation of the arterial wall continuously drive the development of atherosclerotic lesions. Monocytes, as cells of the innate immunity, are particularly involved in this process. In the last decade, heterogeneity of circulating monocytes has widely been acknowledged, and a recent consensus nomenclature subdivides classical, intermediate and nonclassical ...

The biology of lymphocytes is regulated by a large and seemi& growing number of soluble and cell-associated species. A current list includes: interleukins IL l-7, interferons, antigen and perhaps CD4 and cytokines derived from non-lymphoid tissues such as neuropepride, steroid and admnergic hormones. The quality and quantity of regulators present in the B cell milieu during an immunologic insul...

This chapter is devoted to the study of rational subsets of groups, with particular em-phasis on the automata-theoretic approach to finitely generated subgroups of free groups. Indeed,Stallings’ construction, associating a finite inverse automaton with every such subgroup, inaugu-rated a complete rewriting of free group algorithmics, with connections to other fields such astopol...

In this review I shall survey various properties of lymphocytes which allow clear distinctions to be drawn between different lymphocyte subsets. I shall discuss only thymus-derived (T) lymphocytes since these cells appear to play a key role in regulating the activities of other lymphoid cells (B cells and macrophages) as well as carrying out effector functions themselves. In the first section I...

Default unification operations combine strict information with information from one or more defeasible feature structures. Many such operations require finding the maximal subsets of a set of atomic constraints that are consistent with each other and with the strict feature structure, where a subset is maximally consistent with respect to the subsumption ordering if no constraint can be added t...
