introduction: the purpose of this study was to evaluate the morphologic surface of gutta­percha cones after cutting with different methods. materials and methods: the apical 3 millimeters of forty standardized, gutta-percha cones size 40 were cut off using scissors or a scalpel against a glass slab. the samples were then examined under scanning electron microscopy (sem) for topographic deformit...

In this paper we used high resolution satellite imagery in order to study the Pordenone Mountain forests (Friuli Venezia Giulia North-East of Italy). Our aim is to develop a method able to estimate wood biomass using a vegetation index (NDVI Normalized Difference Vegetation Index). In order to do this we analysed a Quickbird satellite image, dated 24 June 2003, and we compared our results with ...

Max-product ‘belief propagation’ (BP) is a popular distributed heuristic for finding the Maximum A Posteriori (MAP) assignment in a joint probability distribution represented by a Graphical Model (GM). It was recently shown that BP converges to the correct MAP assignment for a class of loopy GMs with the following common feature: the Linear Programming (LP) relaxation to the MAP problem is tigh...

Mixed-integer rounding (MIR) is a simple, yet powerful procedure for generating valid inequalities for mixed-integer programs. When used as cutting planes, MIR inequalities are very effective for mixed-integer programming problems with unbounded integer variables. For problems with bounded integer variables, however, cutting planes based on lifting techniques appear to be more effective. This i...

There are two fundamental problems motivated by Silverman’s conversations over the years concerning nature of exact values canonical heights $$f(z)\in \bar{\mathbb {Q}}(z)$$ with $$d:=\deg (f)\ge 2$$ . The first problem is conjecture that $$\hat{h}_f(a)$$ either 0 or transcendental for every $$a\in \mathbb {P}^1(\bar{\mathbb {Q}})$$ ; this holds when f linearly conjugate to $$z^d$$ $$\pm C_d(z)...

We consider a family of heights defined by the $L_p$ norms polynomials with respect to equilibrium measure lemniscate for $0 \le p \infty$, where $p=0$ corresponds geometric mean (the generalized Mahler measure) and $p=\infty$ standard supremum norm. This special choice allows find an explicit form polynomial, estimate it via certain resultant. For lemniscates satisfying appropriate hypotheses,...

BACKGROUND Interactions between nutrition and infections in developing countries are complex, and analyses of the interrelations require data from longitudinal studies that span several years and a comprehensive framework facilitating the formulation of food and health policies. OBJECTIVE The effects of dietary intakes in the Philippines for birth outcomes, heights, weights, and morbidity dur...

We show the existence of canonical heights (normalized heights) of subvarieties for bounded sequences of morphisms and give some applications.
