Universality on higher order Hardy spaces

We prove a Seidel-Walsh-type theorem about universality of a sequence of derivation-composition operators generated by automorphisms of the unit disk in the setting of the higher order Hardy spaces. Moreover, some related positive or negative assertions involving interpolating sequences and sequences between two tangent circles are established for the class of bounded functions in the unit disk. Our statements improve earlier ones due to Herzog and to the first and third authors.Plan Andaluz de Investigación (Junta de Andalucía)Dirección General de Enseñanza Superior (DGES).

Estudio clínico-fisioterapéutico comparativo, mediante tres modalidades de electroterapia, en el tratamiento de la hiperhidrosis

Entre los tratamientos propuestos para el problema de la hiperhidrosis, consideramos a la iontoforesis como un método conservador de esta patología de aplicación fácil y seguimiento programable en cada caso. Para ello se establecieron 6 subgrupos de estudio de pacientes afectos a los que se les comparó con un grupo control de pacientes normales. Tras la elaboración de historia clínica y exploración de los pacientes mediante técnicas específicas se administraron distintos tipos de corrientes en la modalidad de aplicción con iontoforesis más agua corriente así como protocolos diferentes en relación a secuencia y amplitud. Seguidamente se hizo un estudio clínico comparativo entre ellos, acompañado de estudio histoquímico pre y postratamiento. Los resultados obtenidos aportan perspectivas esperanzadoras para este tipo de afecciónTesis Univ. de Granada. Departamento de Enfermería. Leída el 4 de abril de 200

Renormalization of vector fields with mass-like coupling in curved spacetime

Using the method of covariant symbols we compute the divergent part of the effective action of the Proca field with non-minimal mass term. Specifically a quantum abelian vector field with a non-derivative coupling to an external tensor field in curved spacetime in four dimensions is considered. Relatively explicit expressions are obtained which are manifestly local but non polynomial in the external fields. Our result is shown to reproduce existing ones in all particular cases considered. Internal consistency with Weyl invariance is also verified.This work has been partially supported by the Spanish MINECO (Grant no. FIS2017-85053-C2-1-P) and by the Junta de Andalucía (Grant no.

On universality of composition operators in several variables

In this paper we characterize the universality of a sequence of composition operators generated by automorphisms of the N-dimensional unit polydisc DN, on Hardy spaces of DN . In addition, we provide suitable conditions for the universality of partial derivative-composition operators in certain spaces X of holomorphic functions in DN and the N-dimensional unit ball. Our theorems improve or extend earlier ones due to Bourdon and Shapiro, Herzog, León, Bernal and the authors, among others.Dirección General de Enseñanza SuperiorConsejería de Educación (Gobierno de Canarias)Junta de Andalucí

Compositional hypercyclicity equals supercyclicity

In this note it is proved that the sequence of composition operators generated by automorphisms of a simply connected domain strictly contained in the complex plane is hypercyclic –that is, possesses some dense orbit– if and only if it is supercyclic –i.e., possesses some dense projective orbit–. When the domain is the full complex plane, a result in this direction is also obtained. In addition, a number of statements about the corresponding cyclicity properties of single composition operators are either proved directly or extracted as a consequenc

Compositional universality in the N-dimensional ball

It is proved in this note that a sequence of automorphisms on the N-dimensional unit ball acts properly discontinuously if and only if its corresponding sequence of composition operators is universal on the Hardy space of such ball, and if and only if there exists a dense linear manifold of universal functions. Our result completes earlier ones by several authors.Plan Andaluz de Investigación (Junta de Andalucía)Dirección General de Enseñanza SuperiorFondo Europeo de Desarrollo RegionalMinisterio de Educación y Cienci

Maximal cluster sets of L-analytic functions along arbitrary curves

Let Ω be a domain in the N-dimensional real space, L be an elliptic differential operator, and (Tn) be a sequence whose members belong to a certain class of operators defined on the space of L-analytic functions on Ω. It is proved in this paper the existence of a dense linear manifold of L-analytic functions all of whose nonzero members have maximal cluster sets under the action of every Tn along any curve ending at the boundary of Ω such that its ω-limit does not contain any component of the boundary. The above class contains all partial differentiation operators ∂ α, hence the statement extends earlier results due to Boivin, Gauthier and Paramonov, and to the first, third and fourth authors.Plan Andaluz de Investigación (Junta de Andalucía)Ministerio de Ciencia y TecnologíaFondo Europeo de Desarrollo Regiona

Avaliação funcional em idosos intervindos de fratura de quadril

This prospective study was performed in patients aged 65 years or older who underwent hip fracture surgery. The objective was to determine the functional evolution in a group of patients three months after hospital discharge, to identify the variables related to this functional recovery and to describe the associated mortality and institutionalization process. We analyzed demographic variables such as age, sex, and living situation. Other aspects considered included: comorbidity, cognitive impairment, walking ability, dependency level according to Barthel's Index, institutionalization, and mortality. The information was collected on admission and three months after discharge. Considering the entire sample, 89.6% was female and the average age was 83.56 years; 40% of patients regained their prior independence and a 16.7% mortality rate was registered, together with a slight progression toward institutionalization. The functional capacity and cognitive impairment of patients before the fracture are determinants of functional recovery and subsequent recovery of independence.Estudio observacional prospectivo en pacientes mayores de 65 años intervenidos de fractura de cadera. El objetivo fue conocer la evolución funcional de los pacientes a los tres meses del alta hospitalaria, identificar variables relacionadas con dicha recuperación funcional, describir la mortalidad e institucionalización asociadas al proceso. Se analizaron variables demográficas como edad, sexo, convivencia. Otros aspectos registrados fueron: comorbilidad, deterioro cognitivo, capacidad para caminar, nivel de dependencia según índice de Barthel, institucionalización y mortalidad. Se recogió la información al ingreso y a los 3 meses del alta. El 89,6% de la muestra, fueron mujeres, la edad media fue de 83,56 años. El 40% de los pacientes recuperaron la independencia previa registrándose una mortalidad del 16,7% así como una leve progresión hacia la institucionalización. La capacidad funcional y el deterioro cognitivo del paciente, previos a la fractura condicionan su recuperación funcional y dependencias posteriores.Estudo prospectivo de observação, abrangendo doentes com idade superior a 65 anos, submetidos à intervenção cirúrgica por fratura do quadril.

Foram analisadas variáveis como idade, sexo e convivío. Outros aspectos: comorbilidade, deterioração cognitiva, capacidade para se deslocar, nível de dependência segundo índice de Barthel, institucionalização e mortalidade. A informação foi recolhida no momento da admissão e três meses após a alta. Da amostra, 89,6% foram constituídos por mulheres com idade média de 83,56 anos; 40% dos doentes recuperaram a independência anterior, registando-se uma mortalidade de cerca de 16,7% bem como uma ligeira tendência à institucionalização. A capacidade funcional e o grau de deterioração cognitiva antes da fratura condicionam posterior recuperação funcional e consequente nível de dependência

Influencia de la geometría en los máximos de las tensiones en ajustes por interferencia con agujeros ranurados

Memoria D. Samuel Sol rzano Barruso” (USAL, Grant FS/21-2012 and Grant 463AC06).Elastic stress distributions in interference fits match the values predicted by pressure cylinders theory only if the two joined parts have the same length. In fact, a heavy stress concentration in the radial component appears at the edges of the contact zone being more intense in the case of the hub. Many methods have been proposed for relieving the stress peaks. In order to investigate how the stress concentrations are reduced, in this paper, different stress analysis in interference fits with grooved hubs were carried out using the finite element method.The authors wish to acknowledge the financial support provided by the Spanish Institution “Memoria D.
