The relationship between context, structure, and processes with outcomes of 6 regional diabetes networks in Europe
2018
BackgroundWhile health service provisioning for the chronic condition Type 2 Diabetes (T2D) often involves a network of organisations and professionals, most evidence on the relationships between the structures and processes of service provisioning and the outcomes considers single organisations or solo practitioners. Extending Donabedian's Structure-Process-Outcome (SPO) model, we investigate how differences in quality of life, effective coverage of diabetes, and service satisfaction are associated with differences in the structures, processes, and context of T2D services in six regions in Finland, Germany, Greece, Netherlands, Spain, and UK.MethodsData collection consisted of: a) systemat…
Branching Ratios and Spectral Functions of $\tau$ Decays: final ALEPH measurements and physics implications
2005
The full LEP-1 data set collected with the ALEPH detector at the $Z$ pole during 1991-1995 is analysed in order to measure the $\tau$ decay branching fractions. Extensive systematic studies are performed, in order to match the large statistics of the data sample corresponding to over 300 000 measured and identified $\tau$ decays. Branching fractions are obtained for the two leptonic channels and eleven hadronic channels defined by their respective numbers of charged particles and $\pi^0$'s. Using previously published ALEPH results on final states with charged and neutral kaons, corrections are applied to the hadronic channels to derive branching ratios for exclusive final states without kao…
QCD NLO with Powheg matching and top threshold matching in WHIZARD
2016
We present the status of the automation of NLO processes within the event generator WHIZARD. The program provides an automated FKS subtraction and phase space integration over the FKS regions, while the (QCD) NLO matrix element is accessed via the Binoth Les Houches Interface from an externally linked one-loop program. Massless and massive test cases and validation are shown for several e+e- processes. Furthermore, we discuss work in progress and future plans. The second part covers the matching of the NRQCD prediction with NLL threshold resummation to the NLO continuum top pair production at lepton colliders. Both the S-wave and P-wave production of the top pair are taken into account in t…
Calibration of a small anode germanium well detector
2017
SAGe kolokiteen kalibroinnit suoritettiin kolmelle näytegeometrialle. Kaksi geometrioista oli sylinterin muotoisia purkkeja, jotka mitattiin ilmaisimen päällä ja yksi koeputki, joka mitattiin kolon sisällä. Piikkitehokkuuskalibrointi tehtiin NPL:sta tilattujen sertifioitujen näytteiden avulla. Yksinuklidinäytteitä valmistettiin radioaktiivisista liuoksista totaalitehokkuuskalibrointia varten. Totaalitehokkuuskäyrä saatiin simuloimalla totaalitehokkuudet MCNP:llä ja sovittamalla malli vastaamaan kokeellisia tuloksia. Kalibraatiot tehtiin energiavälille 30 keV–1.9 MeV. Kalibroinnit olivat tarpeeksi luotettavia, että ilmaisinta voidaan käyttää akkreditoiduissa gammaspektrometrisissä mittauksis…
The two-loop gluino's corrections on the inclusive b ---> x(s) gamma decay in the CP violation MSSM with large tan beta
2004
We investigate two-loop gluino corrections to the effective Lagrangian for b ! s g in the minimal supersymmetric extension of the standard model (MSSM) at large tan , including the contributions in which quark flavor change is mediated by charginos. Using the translation invariance of loop momenta and the Ward-Takahashi identities that are required by the SU3 c U1 em gauge invariance, we simplify our expressions to concise forms. As an example, we discuss two-loop gluino corrections to the CP asymmetry of inclusive B ! Xs decay in CP violating MSSM. peerReviewed
Analysis of corrective feedback in a multilingual classroom context from a CLIL perspective.
2017
Esta tesis doctoral analiza el feedback correctivo en una clase plurilingüe desde una perspectiva CLIL. El objetivo de este estudio es examinar el feedback que tiende a ser utilizado cuando se corrigen los errores orales en clase comparando diferentes asignaturas, todas ellas impartidas en lengua inglesa. Para ello se analiza la relación entre tipos de feedback y tipos de errores en diferentes asignaturas. Lo que se intenta averiguar es qué estrategias normalmente se eligen para corregir, qué tipo de error es el más frecuente y si hay alguna relación entre tipo de error, el feedback utilizado y la asignatura. Para el estudio se realizaron grabaciones de las clases con video cámara. Las asig…
SST Comparison of AVHRR and MODIS Time Series in the Western Mediterranean Sea
2020
La temperatura de la superficie del mar (SST) es un parámetro clave para comprender los procesos atmosféricos y oceánicos. Desde finales de la década de 1980, las imágenes de satélite infrarrojas se han utilizado para complementar los registros in situ para estudiar la variabilidad temporal y espacial de la SST. El radiómetro avanzado de muy alta resolución (AVHRR) del satélite de la Administración Nacional Oceánica y Atmosférica (NOAA) fue el primer sensor utilizado con éxito para calcular la SST después del desarrollo y validación del algoritmo de corrección atmosférica conocido como 'ventana dividida'. Más recientemente, el espectrorradiómetro de imágenes de resolución MODERADA (MODIS) a…
Sole coloration as an unusual aposematic signal in a Neotropical toad
2019
Many animals have evolved remarkable strategies to avoid predation. In diurnal, toxic harlequin toads (Atelopus) from the Amazon basin, we find a unique colour signal. Some Atelopus populations have striking red soles of the hands and feet, visible only when walking. When stationary, the toads are hard to detect despite their yellow-black dorsal coloration. Consequently, they switch between high and low conspicuousness. Interestingly, some populations lack the extra colour display of the soles. We found comprehensive support that the red coloration can act as an aposematic signal directed towards potential predators: red soles are significantly more conspicuous than soles lacking red colora…
Author Correction: Evaluation of three methods for biomass estimation in small invertebrates, using three large disparate parasite species as model o…
2018
Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. We developed two indirect and non-destructive approaches to estimate biomass of small invertebrates in a simple manner. The first one was based on clay modelling and the second one was based on image analysis implemented with open-source software. Furthermore, we tested the accuracy of the widely used geometric approximation method (third method). We applied these three different methods to three morphologically disparate model species, an acanthocephalan worm, a crustacean and a flatworm. To …
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…
