Constraining interactions mediated by axion-like particles with ultracold neutrons
2015
We report a new limit on a possible short range spin-dependent interaction from the precise measurement of the ratio of Larmor precession frequencies of stored ultracold neutrons and Hg199 atoms confined in the same volume. The measurement was performed in a ~1μT vertical magnetic holding field with the apparatus searching for a permanent electric dipole moment of the neutron at the Paul Scherrer Institute. A possible coupling between freely precessing polarized neutron spins and unpolarized nucleons of the wall material can be investigated by searching for a tiny change of the precession frequencies of neutron and mercury spins. Such a frequency change can be interpreted as a consequence o…
Gravitational depolarization of ultracold neutrons : comparison with data
2015
We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a variety of vertical magnetic-field gradients. In particular, we have investigated the dependence upon these field gradients of spin depolarization rates and also of shifts in the measured neutron Larmor precession frequency. We find excellent qualitative agreement, with gravitationally enhanced depolarization accounting for several previously unexplained features in the data.
Measurement of the neutron electric form factor
2003
Abstract The neutron electric form factor GE,n has been measured at three different four-momentum transfer in a D(|e|→, e′|e|→)p experiment. Neutronwere detected in a recoil 0 polarimeter, using a spin precession method. We present the experiment and the status of data analysis.
Therapeutic algorithms for chronic hepatitis C in the DAA era during the current economic crisis: whom to treat? How to treat? When to treat?
2012
The advent of triple therapy (TT) with first-generation protease inhibitors boceprevir (BOC) and telaprevir (TVR) in addition to pegylated interferon and ribavirin resulted in a significant gain in terms of sustained virological response (SVR) when treating naive or previous treated patients with genotype 1 (G1) chronic hepatitis C (CHC). This gain is partly balanced by the increased complexity of treatment and by the raised costs and risks of therapy, making necessary to optimize the indication to TT. Specifically, the identification of patient needing to TT over DT, the choice of the more correct therapeutic approach according to baseline and on treatment SVR predictors, and the timing of…
Effects of external imbalances on GDP recovery patterns
2021
Abstract A decade after the beginning of the Great Recession, flow external imbalances, measured by the current account (CA) have narrowed markedly. However, stock or net foreign assets (NFA) imbalances have kept increasing and have created challenges for future macroeconomic and financial stability. To date, early warning systems (scoreboards) have focused more on flow than on stock variables. To approach this problem, in this paper we analyze expansions using two complementary sets of indicators proposed by Harding and Pagan (2002) and Gadea et al. (2017) for the period 1950–2016. After controlling for a large set of explanatory variables, we find that the effect of CA imbalances is limit…
Prospects for the return of Spanish scientists in the United Kingdom during the Great Recession
2021
The economic crisis that began in 2008 caused an increase in skilled Spanish emigration, including scientists, many of whom settled in the United Kingdom. The objective of this article is to analys...
Proyecto migratorio y trayectorias laborales de cuidadoras latinoamericanas: efectos de la Gran Recesión. Un estudio cualitativo en el Área Metropoli…
2021
Este texto aborda el proyecto migratorio y las trayectorias laborales de mujeres latinoamericanas que trabajan como cuidadoras en el ámbito doméstico en el Área Metropolitana de Valencia. A partir del uso de una metodología cualitativa se llega a varias conclusiones: existe una explicación multicausal de los proyectos migratorios, predominando los de carácter económico/laboral, y, en segundo lugar, sus trayectorias laborales se caracterizan por el mantenimiento en las mismas ocupaciones con ligeros cambios, o con modificaciones en sectores muy concretos. Además, la Gran Recesión ha afectado de manera negativa aquellas que habían visto levemente mejoradas sus posiciones en el mercado laboral…
Gingival recession associated with Orthodontic treatment and root coverage
2010
Many patients seek to pursue orthodontic treatment for esthetic improvement. These patients present with mal- alignment of the anterior teeth. There was strong correlation between the severity and extent of gingival recessions and past orthodontic treatment, it was suggested that orthodontic tooth movement may lead to gingival recession. The principal objective in the treatment of gingival recession is to cover the exposed root surfaces to improve es- thetics and to reduce hypersensitivity. Different soft tissue grafting procedures have been proposed in the treatment of gingival recessions. Free gingival grafts (FGG) are a reliable method for treatment of gingival recessions: An autograft i…
Interdisciplinary approach for the treatment of periodontally compromised malpositioned anterior teeth: a case report
2009
Today many adult patients with periodontal disease demonstrate positioning of teeth that comprise their ability for proper mechanical tooth cleaning of approximal tooth surfaces. With adequate combined periodontal-orthodontic treatment it is possible to re-establish a healthy and well-functioning dentition. However, while orthodontic treatment can realign periodontally affected teeth, esthetic appearance may be compromised by gingival recession due to alveolar bone dehiscences or fenestrations in combination with a thin gingival biotype. This article reports an interdisciplinary (periodontic, orthodontic, restorative) approach for the treatment of a periodontally compromised patient with an…
Classification of Gingival Recession
2018
Gingival recession is a common finding in many patients and is clinically manifested by an apical displacement of the gingival margin in relation to the cemento-enamel junction (CEJ). Various classification systems have been proposed to classify gingival recession defects and to predict final root coverage outcomes. Among them, the Miller classification is still the most commonly used among dental practitioners and researchers. This chapter reviews the different classification systems available for gingival recession defects and explores the strengths and limitations of them.
