G-CLASS: geosynchronous radar for water cycle science – orbit selection and system design
2019
The mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on timescalesless than a day are very poorly observed from space. G-CLASS, using C-band geosynchronous radar, could transform this. Itsscience objectives address intense storms and high resolution weather prediction, and significant diurnal processes such assnow melt and soil moisture change, with societal impacts including agriculture, water resource management, flooding, andlandslides. Secondary objectives relate to ground motion observations for earthquake, volcano, and subs…
Determinanty współpracy studentów i wykładowców jako czynnik optymalizacji zawodowego przygotowania nauczycieli w Polsce i na Ukrainie
2015
W artykule postawiono tezę, że głównym zadaniem nauk pedagogicznych jest stworzenie prawidłowo funkcjonującego systemu edukacji zawodowej przyszłego nauczyciela, nakreślenie kierunków ukraińskich innowacji, jak również możliwości współpracy w tych sektorach ukraińskich i polskich nauczycieli. W artykule poruszono również problem interakcji pedagogicznej jako społecznej i psychologicznej adaptacji i dostosowania procesu tworzenia i rozwoju osobistego przyszłego nauczyciela w kontekście globalizacji społeczeństwa opartego na wiedzy.
Norma y variación lingüística: paralelismos y divergencias entre el español y el catalán
2013
Este artículo analiza la presencia de la variación lingüística de carácter dialectal en la norma académica o modelo de lengua estándar del español y del catalán. Esta variación se manifiesta a través de la aceptación de alternativas normativas, también conocida como polimorfismo. El estudio se centra en la lengua escrita, concretamente en el nivel ortográfico, en el morfológico y en el sintáctico, y analiza los contenidos de las principales obras académicas de estas dos lenguas. El hecho de tratarse de lenguas con una situación sociolingüística diferente tiene consecuencias en la manera de concebir el posible polimorfismo y también en la forma de aplicarlo, ya que entra en conflicto la defe…
The migration–tourism nexus in the EU28
2020
This study explores the nexus between tourism and migration on an intra-European scale over the period 2000–2015. Complex-network analysis and gravity models were the investigation methods preferred. For each year under study, we built two country-to-country networks to map and reveal the connections between states as shaped by migration stocks and tourism flows, respectively. Then, the main determinants of the correlation patterns between the two networks were investigated by several econometric analysis. Results point to a quite similar topological structure for the tourism and migration networks as well as to a significant and reciprocal direct influence between tourism and migration mo…
Standards for the diagnosis and management of complex regional pain syndrome: Results of a European Pain Federation task force.
2019
Background: Complex regional pain syndrome is a painful and disabling post-traumatic primary pain disorder. Acute and chronic complex regional pain syndrome (CRPS) are major clinical challenges. In Europe, progress is hampered by significant heterogeneity in clinical practice. We sought to establish standards for the diagnosis and management of CRPS. Methods: The European Pain Federation established a pan-European task force of experts in CRPS who followed a four-stage consensus challenge process to produce mandatory quality standards worded as grammatically imperative (must-do) statements. Results: We developed 17 standards in 8 areas of care. There are 2 standards in diagnosis, 1 in multi…
A Novel Approach to Identify Candidate Prognostic Factors for Hepatitis C Treatment Response Integrating Clinical and Viral Genetic Data
2015
The combined therapy of pegylated interferon (IFN) plus ribavirin (RBV) has been for a long time the standard treatment for patients infected with hepatitis C virus (HCV). In the case of genotype 1, only 38%–48% of patients have a positive response to the combined treatment. In previous studies, viral genetic information has been occasionally included as a predictor. Here, we consider viral genetic variation in addition to 11 clinical and 19 viral populations and evolutionary parameters to identify candidate baseline prognostic factors that could be involved in the treatment outcome. We obtained potential prognostic models for HCV subtypes la and lb in combination as well as separately. We …
The Higgs Era
2016
Después del descubrimiento de un bosón escalar con masa alrededor de 125, el Modelo Estándar parece funcionar perfectamente, pero todavía hay mucho espacio (y necesidad) para nueva física. A pesar de su enorme éxito, el Modelo Estándar deja muchas preguntas sin responder y muchas cuestiones abiertas. A falta del conocimiento de una simetría fundamental de la Naturaleza que nos indique el camino, hemos de analizar fenomenologicamente cualquier extensión del Modelo que pueda responder al menos a alguna de estas preguntas. En este trabajo estudiamos dos tipos de extensiones del Modelo Estándar, las dos relacionadas con el sector escalar. En la primera parte de la tesis estudiamos la posible ex…
Review of Particle Physics
2020
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, …
Typology and Representation of Alterations in Territorial Units: A Proposal
2018
Abstract This article proposes a typology of boundary changes in territorial units at two points in time. The different types of changes are organized in a hierarchy and represented homogeneously, independently of the number of territorial units involved and of the changes to them. Each alteration is described precisely and unambiguously, and it is codified to allow the information to be treated automatically. In addition to providing efficient storage of the information about these changes, a canonical representation facilitates the automatic detection of inconsistencies in the database. At the same time, the typology allows us to define backward and forward equivalence rules, which helps …
