J.E. Hirsch (2005) introduced the h-index to quantify an individual’s scientific research output by the largest number h of a scientist’s papers that received at least h citations. To take into account the highly skewed frequency distribution of citations, L. Egghe (2006a) proposed the g-index as an improvement of the h-index. I have worked out 26 practical cases of physicists from the Institut...

We study serial coalgebras by means of their valued Gabriel quivers. In particular, Hom-computable and representation-directed coalgebras are characterized. The Auslander-Reiten quiver of a serial coalgebra is described. Finally, a version of Eisenbud-Griffith theorem is proved, namely, every subcoalgebra of a prime, hereditary and strictly quasi-finite coalgebra is serial. Introduction A syste...

O livro de autoria Paul Tillich (1985) aborda, em poucas páginas e uma linguagem aparentemente fácil, o tema apontado no título. encontra-se dividido seis capítulos várias subseções, tornando-se cada vez mais complexo à medida que autor relaciona da fé com outros aspectos vida humana. Seu objetivo é discursar sobre a fé, definindo-a e, tal como retratado título, explanando sua dinâmica.

The Boundary Representation of a 3D manifold contains FACES (connected subsets of a parametric surface S : R −→ R). In many science and engineering applications it is cumbersome and algebraically difficult to deal with the polynomial set and constraints (LOOPs) representing the FACE. Because of this reason, a Piecewise Linear (PL) approximation of the FACE is needed, which is usually represente...

Given a set S of points in the plane, the k-Gabriel graph of S is the geometric graph with vertex set S, where pi, pj ∈ S are connected by an edge if and only if the closed disk having segment pipj as diameter contains at most k points of S \ {pi, pj}. We consider the following question: What is the minimum value of k such that the k-Gabriel graph of every point set S contains a Hamiltonian cyc...

of prophylactic strategy in cardiac disorders. Furthermore, the impact of cardiac failure on hepatic function is presented in a practical, useful manner. Synthetic and concise, as required for a practical work, the book reflects the scientific level of the year 2014. There are also new approaches in the field of genetics, immunohistochemistry, molecular biology and neurogastroenterology. The ap...

Do you have any regrets or bugbears? Like many others I regret not knowing more maths. Although perhaps I should be careful what I wish for, as being more mathematically-savvy might prevent the occasional leaps of faith that make the naturalistic aspects of my research exciting. Bugbears: there’s definitely a few, but for brevity’s sake I’ll mention just two. Like everyone else, I find the peer...
