let g(v,e) be a graph with p vertices and q edges. a graph g is said to have an odd mean labeling if there exists a function f : v (g) → {0, 1, 2,...,2q - 1} satisfying f is 1 - 1 and the induced map f* : e(g) → {1, 3, 5,...,2q - 1} defined by f*(uv) = (f(u) + f(v))/2 if f(u) + f(v) is evenf*(uv) = (f(u) + f(v) + 1)/2 if f(u) + f(v) is odd is a bijection. a graph that admits an odd mean lab...

A morpho-syntactic tagger associates to each word of a corpus a label which recapitulates its morpho-syntatic properties in the text. In corpora from oral data, not only do we have to face the usual problem of multi-labels words, but also the more specific problems of disfluences (repetitions, ungrammatical constructions...), of non existing words and of the lack of punctuation marks [1]. First...

a graph of size n is said to be graceful when is possible toassign distinct integers from {0, 1, . . . , n} to its verticesand {|f(u)−f(v)| : uv ∈ e(g)} consists of n integers. inthis paper we present broader families of graceful graphs; these families are obtained via three different operations: the third power of a caterpillar, the symmetric product of g and k2 , and the disjoint :union: of g...

Hypoxia and erythropoietin (EPO) were a couple from the very beginning. Hypoxia induces the production of EPO, which became the paradigm for oxygen-regulated gene expression [1]. Dissecting EPO gene regulation has lead to the discovery of the transcription factor complex hypoxia inducible factor-1 (HIF-1), the widespread “master regulator of O2 homeostasis” in the tissue, and the identification...

Apresentado em 2018, como uma Conferência na Universidade Federal da Paraíba, João Pessoa, o presente artigo trata combinação de dois conceitos. Com a aproximação dos conceitos que se expõem já no título deste texto conferência sua origem – “utopia concreta”, cerne do pensamento Ernst Bloch e imensa obra filosófica tão original, dialética barroca, “homem cordial”, criação análise Brasil feita p...
