Nevus sebáceo cerebriforme: uma rara apresentação*
A 13-year-old boy presented congenital, raised, yellowish colored plaques with fi broelastic consistency, which were velvety in appearance, alopecic, with clearly defi ned limits and sulci or well-marked meandering invaginations, a cerebriform appearance on the upper part of the right ear, accompanied by alopecia in the temporomandibular region-parietal. The lesion was asymptomatic. Histopathol...
متن کاملN 20��: Year of Chemistry
dent’s standard text on the theory of chemical bonding was Charles Coul son’s Valence (1952). Absent from it was this theoretical chemist’s real view on the sticks that generations of students have drawn to link atoms into molecules. “A chemical bond is not a real thing: it does not exist: no one has ever seen it, no one ever can. It is a figment of our own imagination,” he later wrote. There ...
متن کاملJa n 20 08 NUMERICAL PRIMARY DECOMPOSITION
Consider an ideal I ⊂ R = C[x] = C[x 1 ,. .. , x n ] defining a complex affine variety X = V (I) = {x ∈ C n | ∀f ∈ I, f (x) = 0}. We describe the associated components VAss(I) = {V (P) | P ∈ Ass(I)} by means of numerical primary decomposition (NPD). The method is based on the construction of deflation ideal I (d) that defines the deflated variety X (d) = V (I (d)) in a higher-dimensional comple...
متن کاملJa n 20 09 The trapped region
I will discuss some recent results on marginally outer trapped surfaces, apparent horizons and the trapped region. A couple of applications of the results developed for marginally outer trapped surfaces to coalescence of black holes and to the characterization of the trapped region are given.
متن کاملJu n 20 06 COMPARING HOMOTOPY CATEGORIES
Given a suitable functor T : C → D between model categories, we define a long exact sequence relating the homotopy groups of any X ∈ C with those of TX , and use this to describe an obstruction theory for lifting an object G ∈ D to C. Examples include finding spaces with given homology or homotopy groups.
