Polymer Measure: Varadhan's Renormalization Revisited
Through chaos decomposition we improve the Varadhan estimate for the rate of
convergence of the centered approximate self-intersection local time of planar
Brownian motion.Comment: 5 page
Hydrodynamic limits for the free Kawasaki dynamics of continuous particle systems
An infinite particle system of independent jumping particles is considered.
Their constructions is recalled, further properties are derived, the relation
with hierarchical equations, Poissonian analysis, and second quantization are
discussed. The hydrodynamic limit for a general initial distribution satisfying
a mixing condition is derived. The large time asymptotic is computed under an
extra assumption
PERMANENT EDUCATION AND ITS INTERFACE WITH BEST NURSING PRACTICES IN PRIMARY HEALTH CARE
Objetivo: analizar la implicancia del proceso de educación permanente para el desarrollo de las mejores prácticas de Enfermería en la Atención Primaria de la Salud. Metodología: estudio cuanti-cualitativo, realizado en dos macroregionesde salud del estado de Santa Catarina – Brasil. La muestra cuantitativa estuvo compuesta por 216 enfermeros, de 97 municipios. Los datos se obtuvieron mediante la aplicación de un cuestionario y se los analizó a través de estadística descriptiva. Los datos cualitativos se produjeron a través de grupos focales, en tres municipios, y se los analizó con la ayuda del programa Atlas.ti 8.0®. Resultados: 174 enfermeros (80,6%) poseen alguna especialización. 200 (92%) participan de procesos de educación permanente, incluyendo intercambio de experiencias y actualización,destacándose el programa Telessaúde (Telesalud). Los discursos originaron cinco code groups: compartir saberes y experiencias; el conocimiento y la experiencia califican la práctica; educación: liberación y cambio; integración enseñanza-servicio; y tiempo para aprender. Conclusión: los procesos de educación permanente entran en contacto tangencial con conceptos de la educación liberadora y apuntan a la experiencia y al uso de evidencias.Objetivo: analisar a implicação do processo de educação permanente para o desenvolvimento das melhores práticas em enfermagem na Atenção Primária à Saúde.Método: estudo quanti-qualitativo, realizado em duas macrorregiões de saúde do estado de Santa Catarina – Brasil.

The sample was made up of 216 nurses, from 97 municipalities. The data were obtained by applying a questionnaire, and analyzed using descriptive statistics. The qualitative data were produced by means of focus groups, in three municipalities, and analyzed with the aid of Atlas.ti 8.0®.Results: A total of 174 nurses (80.6%) have some specialization. 200 (92%) participate in permanent education processes, including exchange of experiences and updates, with Telessaúde (Telehealth) standing out. The discourses originated five code groups: sharing knowledge and experiences; knowledge and experience qualify the practice; education: liberation and change; teaching-service integration, and time to learn.Conclusion: the permanent education processes approach concepts of liberating education and point to the experience and use of evidence

Positive sesquilinear form measures and generalized eigenvalue expansions
Positive operator measures (with values in the space of bounded operators on
a Hilbert space) and their generalizations, mainly positive sesquilinear form
measures, are considered with the aim of providing a framework for their
generalized eigenvalue type expansions. Though there are formal similarities
with earlier approaches to special cases of the problem, the paper differs e.g.
from standard rigged Hilbert space constructions and avoids the introduction of
nuclear spaces. The techniques are predominantly measure theoretic and hence
the Hilbert spaces involved are separable. The results range from a Naimark
type dilation result to direct integral representations and a fairly concrete
generalized eigenvalue expansion for unbounded normal operators.Comment: 23 pages, to appear in J. Math. Anal. App
Hybrid architecture for shallow accumulation mode AlGaAs/GaAs heterostructures with epitaxial gates
Accumulation mode devices with epitaxially grown gates have excellent electrical stability due to the absence of dopant impurities and surface states. We overcome typical fabrication issues associated with epitaxially gated structures (e.g., gate leakage and high contact resistance) by using separate gates to control the electron densities in the Ohmic and Hall bar regions. This hybrid gate architecture opens up a way to make ultrastable nanoscale devices where the separation between the surface gates and the 2D electron gas is small. In this work, we demonstrate that the hybrid devices made from the same wafer have reproducible electrical characteristics, with identical mobility and density traces over a large range of 2D densities. In addition, thermal cycling does not influence the measured electrical characteristics. As a demonstration of concept, we have fabricated a hybrid single-electron transistor on a shallow (50 nm) AlGaAs/GaAs heterostructure that shows clear Coulomb blockade oscillations in the low temperature conductance.This project was supported by the Australian Government under the Australia-India Strategic Research Fund and by the Australian Research Council (ARC) DP scheme.
