Subspaces with extra invariance nearest to observed data
(Elsevier Inc, 2016-09)
Given an arbitrary finite set of data F = {f1, ..., fm} ⊂ L2(Rd) we prove the existence and show how to construct a “small shift invariant space” that is “closest” to the data F over certain class of closed subspaces of ...
Maximal operators, Riesz transforms and Littlewood–Paley functions associated with Bessel operators on BMO
(Academic Press Inc Elsevier Science, 2010-03)
In this paper we study boundedness properties of certain harmonic analysis operators (maximal operators for heat and Poisson semigroups, Riesz transforms and Littlewood–Paley g-functions) associated with Bessel operators, ...

Riesz bases of exponentials on unbounded multi-tiles
(American Mathematical Society, 2018-01)
We prove the existence of Riesz bases of exponentials of L2(Ω), provided that Ω ⊂ ℝd is a measurable set of finite and positive measure, not necessarily bounded, that satisfies a multi-tiling condition and an arithmetic ...
The MetaCyc database of metabolic pathways and enzymes and the BioCyc collection of pathway/genome databases
(Oxford University Press, 2016-01)
The MetaCyc database (MetaCyc.org) is a freely accessible comprehensive database describing metabolic pathways and enzymes from all domains of life. The majority of MetaCyc pathways are small-molecule metabolic pathways ...
Estudio de problemas de reconstrucción de funciones en espacios de Paley Wiener asociados a medidas singulares o grupos localmente compactos abelianos: aplicaciones al estudio de núcleos positivos en el espacio de Hardy
(2020-04-27)
La tesis se encuentra dividida en dos partes: • Parte I: Técnicas de espacios modelos en el estudio de desarrollos de Fourier en espacios L 2 asociados a medidas singulares • Parte II: Conjuntos de muestreo y de interpolación ...

Lp-dimension free boundedness for Riesz transforms associated to Hermite functions
(Springer, 2004-04)
Riesz transforms associated to Hermite functions were introduced by S. Thangavelu, who proved that they are bounded operators on L^p(R^d ), 1 < p < ∞ . In this paper we give a different proof that allows us to show that ...
Views on the form-function correlation and biological design
(Springer, 2019-09-16)
The linkage between form and function is a fascinating field for intellectual analysis and contemplation in natural sciences by naturalists, biologists, anatomists, as well as philosophers and theologians. In the early ...
