Fig. 3. The thoracoabdominal wall could not be totally covered with the latissimus dorsi myocutaneous free flap; therefore, Permacol was applied to the remaining defect measuring about 12 cm×7 cm. (A) Immediately after flap transfer, generalized congestion was noted. (B) On postoperative day 2, the peripheral of the flap started to necrotize. (C) After debridement of the devitalized part, two-t...

Idiopathic gingival fibromatosis is a relatively rare condition characterized by the proliferation of the gingival tissues resulting in masticatory, esthetics, phonetics and psychological disturbances. We present a case with generalized diffuse gingival enlargement involving the maxillary and mandibular arches extending on buccal and lingual/ palatal surfaces and covering incisal/occlusal third...

We characterize the edge-signed graphs in which every 'significant' positive closed walk (or combination of walks) has even length, under seven different criteria for significance, and also those edge-signed graphs whose double covering graph is bipartite. If the property of even length is generalized to positivity in a second edge signing, the characterizations generalize as well. We also char...

For general broadcast protocols, the natural generalization of the Karp and Miller procedure does not terminate; even the problem of deciding if a broadcast protocol may exhibit an infinite behavior is undecidable [4]. We define a subclass of broadcast protocols, called entropic broadcast protocols, which "contains" the MESI protocol, and we prove that the Generalized Karp and Miller procedure ...

We define iterated monodromy groups of more general structures than partial self-covering. This generalization makes it possible to define a natural notion of a combinatorial model of an expanding dynamical system. We prove that a naturally defined “Julia set” of the generalized dynamical systems depend only on the associated iterated monodromy group. Many examples, in particular models for a s...

We show in this paper that arbitrary pole assignment by memoryless feedback is generically possible in the class of generalized first order system of a fixed McMillan degree n as soon as n is strictly less than the input number times the output number. Our result generalizes results by the authors covering the situation when the set of plants consists of strictly proper transfer functions only.

A covering of a multigraph G is a subset of edges which meet ail vertices of G. Partitions of the edges of G into coverings Ci, C2,..., Ck are considered. In particular we examine how close the cardinalities of thèse coverings may be. A resuit concerning matchings is extended to the décomposition into coverings. Finally thèse considérations are generalized to the décompositions of the vertices ...

Rough set theory provides a systematic way for rule extraction, attribute reduction and knowledge classification in information systems. Some measurements are important in rough sets. For example, information entropy, knowledge dependency are useful in attribute reduction algorithms. This paper proposes the concepts of the lower and upper covering numbers to establish measurements in covering-b...
