Consideraciones sobre cuerpos ordenados y cuerpos reales maximales
El presente trabajo se puede considerar como prolongación del trabajo (I) del autor, se amplía un resultado de este último que era válido sólo en el caso metrizable, y aquí se estudia el caso general; se hace un estudio ...
Division and extension in weighted Bergman-Sobolev spaces
Let D be a bounded strictly pseudoconvex domain of Cn with C 8 boundary and Y = {z; u1(z) = ... = ul(z) = 0} a holomorphic submanifold in the neighbourhood of D', of codimension l and transversal to the boundary of D. In ...
Grab, Pay, and Eat: Semantic Food Detection for Smart Restaurants
The increase in awareness of people toward their nutritional habits has drawn considerable attention to the field of automatic food analysis. Focusing on self-service restaurants environment, automatic food analysis is not ...
A picture of solar-sail heteroclinic enhanced connections between lissajous libration point orbits
The dynamics of solar-sail maneuvers are conceptually different from classical control maneuvers where one considers impulsive changes in the velocity of a spacecraft. Solar-sail orbits are continuous in both position and ...
Escaping points in the boundaries of baker domains
We study the dynamical behaviour of points in the boundaries of simply connected invariant Baker domains $U$ of meromorphic maps $f$ with a finite degree on $U$. We prove that if $f|_U$ is of hyperbolic or simply parabolic ...
Cadenes de Sales discretes
The Sales algebras are the substract of some positive implicational calculi . As a first aproximation to their representation we study the Sales algebras that are discrete and linear . In this paper we present a caracteritzation ...
Localizing with respect to self-maps of the circle
We describe a general procedure to construct idempotent functors on the pointed homotopy category of connected $ {\text{CW}}$-complexes, some of which extend $ P$-localization of nilpotent spaces, at a set of primes $ P$. ...
Reliable computation of robust response tori on the verge of breakdown
We prove the existence and local uniqueness of invariant tori on the verge of breakdown for two systems: the quasi-periodically driven logistic map and the quasi-periodically forced standard map. These systems exemplify ...
Funciones abeloides y aplicaciones a ecuaciones en derivadas parcial es de cuarto orden
EI estudio de las ecuaciones en derivadas parciales, cuyas soluciones estén en el campo real, implica considerar los problemas adecuados a cada ecuación; asi para las de 2º orden y con dos variables independientes resultan ...
Irreducibility of the moduli space of orthogonal instanton bundles on Pn
In order to obtain existence criteria for orthogonal instanton bundles on $\mathbb{P}^n$, we provide a bijection between equivalence classes of orthogonal instanton bundles with no global sections and symmetric forms. Using ...
Real interpolation for families of Banach spaces (II)
In this paper, we study the dual space and reiteration theorems for the real method of interpolation for infinite families of Banach spaces introduced in [2]. We also give examples of interpolation spaces constructed with ...
On fields of definition of torsion points of elliptic curves with complex multiplication
For any elliptic curve $E$ defined over the rationals with complex multiplication (CM) and for every prime $p$, we describe the image of the mod $ p$ Galois representation attached to $E$. We deduce information about the ...
Singular values and bounded Siegel disks
Let $f$ be an entire transcendental function of finite order and $\Delta$ be a forward invariant bounded Siegel disk for $f$ with rotation number in Herman's class . We show that if $f$ has two singular values with bounded ...
Aproximaciones sucesivas de las soluciones de ecuaciones en derivadas parciales de tercer orden
PRÓLOGO En la Asignatura de Doctorado << Ecuaciones en derivadas parciales de tipo hiperbólico>>, nos fue propuesto por el Prof. Dr. AuGÉ la clasificación y reducción a formas canónicas de las ecuaciones cuasi-lineales ...
Bandlimited Lipschitz functions
We study the space of bandlimited Lipschitz functions in one variable. In particular we provide a geometrical description of interpolating and sampling sequences for this space. We also give a description of the trace of ...
Uniform estimates in the Poincare-Aronszajn theorem on the separation of singularities of analytic functions
We study the possibility of splitting any bounded analytic function $f$ with singularities in a closed set $E\cup F$ as a sum of two bounded analytic functions with singularities in $E$ and $F$ respectively. We obtain some ...
Automatic Prediction of Facial Trait Judgments: Appearance vs. Structural Models
Evaluating other individuals with respect to personality characteristics plays a crucial role in human relations and it is the focus of attention for research in diverse fields such as psychology and interactive computer ...
Optimal Polynomial Prediction Measures and Extremal Polynomial Growth
We show that the problem of finding the measure supported on a compact set $K\subset \C$ such that the variance of the least squares predictor by polynomials of degree at most $n$ at a point $z_0\in\C^d\backslash K$ is a ...
Surgery on Herman rings of the complex standard family
We consider the standard family (or Arnold family) of circle maps given by f_{\alpha, \beta}(x)=x + \alpha + \beta \sin(x) \pmod{2\pi}, for x,\alpha\in [0,2\pi), \beta \in (0,1) and its complexification F_{\alpha,\beta}(z)=z ...
DECONbench: a benchmarking platform dedicated to deconvolution methods for tumor heterogeneity quantification
Quantifcation of tumor heterogeneity is essential to better understand cancer progression and to adapt therapeutic treatments to patient specifcities. Bioinformatic tools to assess the diferent cell populations from ...
