A-closure is the equivalent of path consistency for qualitative spatiotemporal calculi with weak composition. We revisit existing attempts to characterize the question whether a-closure is a complete method for deciding consistency of CSPs over such calculi. Renz and Ligozat’s characterization via closure under constraints has been refuted by Westphal, Hué and Wölfl. However, for many commonly ...

in the present investigation, methanolic extract of mimusops elengi  leaves were evaluated for wound healing activity. entire wound healing process is complex series of events that begins at the moment of injury and can continue for months to years. methanolic extract of mimusops elengi leaves were examined for wound healing activity in the form of ointment by the excision, the incision and dea...

conclusions vacuum-assisted abdominal closure is a good technique for temporary abdominal closure. in patients who are unable to achieve fascial closure, skin closure alone is safe. results after 157 trauma laparotomies, 35 (22%) were open abdomen cases with an average injury severity score was 35. ninety-four percent of open abdomens occurred after damage-control surgery. temporary vacuum-assi...

We introduce a new variant of tight closure associated to any fixed ideal a, which we call a-tight closure, and study various properties thereof. In our theory, the annihilator ideal τ(a) of all a-tight closure relations, which is a generalization of the test ideal in the usual tight closure theory, plays a particularly important role. We prove the correspondence of the ideal τ(a) and the multi...

In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity. The existence and uniqueness of T-transitive closure of interval-valued fuzzy relations is proved. An algorithm to compute the T-transitive closure of finite interval-valued fuzzy relations is showed. Some propertie...

In [3] and [6] the concepts of smooth closure, smooth interior, smooth α-closure and smooth α-interior of a fuzzy set were introduced and some of their properties were obtained. In this paper, we introduce the concepts of several types of weak smooth compactness and weak smooth α-compactness in terms of these concepts introduced in [3] and [6] and investigate some of their properties.

In this paper, non-standard tight closure is proposed as an alternative for classical tight closure on finitely generated algebras over C. It has the advantage that it admits a functional definition, similar to the characteristic p definition of tight closure, where instead of the characteristic p Frobenius, its ultraproduct, the non-standard Frobenius, is used. This new closure operation cl(·)...

Closure is a fundamental property of many discrete systems. Transitive closure in relations has been well studied, e.g. 1,14,6,5], as has geometric closure 8,9] and closure in various kinds of graphs 17,10]. The closed sets of a closure operator illustrate a kind of well-behaved internal structure that is the main theme of this paper. In Section 1, we examine antimatroid closure spaces. In Sect...

We consider a generalization of Awad–Shannon entropy, namely Awad–Varma introduce stochastic order on residual entropy and study some properties this order, like closure, reversed closure preservation in models (the proportional hazard rate model, the odds model record values model).
