On admissible tensor products in -adic Hodge theory
We prove that if and are two -pairs whose tensor product is
crystalline (or semi-stable or de Rham or Hodge-Tate), then there exists a
character such that and are crystalline (or
semi-stable or de Rham or Hodge-Tate). We also prove that if is a -pair
and is a Schur functor (for example \Sym^n(-) or ) such
that is crystalline (or semi-stable or de Rham or Hodge-Tate) and if the
rank of is sufficiently large, then there is a character such that
is crystalline (or semi-stable or de Rham or Hodge-Tate). In
particular, these results apply to -adic representations
Serotonin–dopamine interaction : an overview
Central serotonergic and dopaminergic systems play a critical role in the regulation of normal and abnormal behaviours. Moreover, recent evidence suggests that the dysfunction of dopamine (DA) and serotonin (5-hydroxytriptamine, 5-HT) neurotransmission might underlie the pathophysiology of neuropsychiatric disorders, including depression, schizophrenia, attention deficit hyperactivity disorders, drug abuse, Gilles de la Tourette's syndrome and Parkinson's disease.peer-reviewe
Role of serotonin in central dopamine dysfunction
The interaction between serotonin (5-HT) and dopamine (DA)-containing neurons in the brain is a research topic that has raised the interest of many scientists working in the field of neuroscience since the first demonstration of the presence of monoamine-containing neurons in the mid 1960. The bulk of neuroanatomical data available clearly indicate that DA-containing neurons in the brain receive a prominent innervation from serotonin (5-hydroxytryptamine, 5-HT) originating in the raphe nuclei of the brainstem. Compelling electrophysiological and neurochemical data show that 5-HT can exert complex effects on the activity of midbrain DA neurons mediated by its various receptor subtypes. The main control seems to be inhibitory, this effect being more marked in the mesocorticolimbic DA system as compared to the DA nigrostriatal system. In spite of a direct effect of 5-HT by its receptors located on DA cells, 5-HT can modulate their activity indirectly, modifying γ-aminobutyric (GABA)-ergic and glutamatergic input to the ventral tegmental area (VTA) and substantia nigra pars compacta (SNc). Although 5-HT/DA interaction in the brain has been extensively studied, much work remains to be done to clarify this issue. The recent development of subtype-selective ligands for 5-HT receptors will not only allow a detailed understanding of this interaction but also will lead to the development of new treatment strategies, appropriate for those neuropsychiatric disorders in which an alteration of the 5-HT/DA balance is supposed.peer-reviewe
Carbon Dioxide + Fluoromethane and Nitrous Oxide + Fluoromethane: Solid−Liquid Equilibria Measurements
A recently built experimental setup was employed for the estimation of the solid-liquid equilibria (SLE) of alternative refrigerant systems. The behavior of two binaries, that is, carbon dioxide + fluoromethane (CO2 + R41) and nitrous oxide + fluoromethane (N2O + R41), was measured down to temperatures of 126.5 K. To confirm the reliability of the apparatus, the triple points of the pure fluids constituent of the binary systems were measured. All triple-point data measured revealed a generally good consistency with the literature. The results obtained for the mixtures were corrected by the Rossini method and interpreted by means of the Schröder equation. © 2010 American Chemical Society
Anisotropic Effects of Oxygen Vacancies on Electrochromic Properties and Conductivity of -Monoclinic WO
Tungsten trioxide (WO) is a paradigmatic electrochromic material, whose
peculiar optical properties in the presence of oxygen vacancies or intercalated
alkali atoms have been observed and investigated for a long time. In this paper
we propose a rationalization of experiments based on first-principles
calculations of optical and electrical properties of oxygen deficient (reduced)
WO. Our approach is based on a parameter-free dielectric-dependent hybrid
density functional methodology, used in combination with the charge transition
levels formalism, for studying excitation mechanisms in the presence of
defects. Our results indicate that oxygen vacancies lead to a different physics
in -monoclinic WO, depending on the orientation of the W-O-W chain
where the vacancy is created, thus evidencing strong anisotropic effects rooted
in the peculiar structural properties of the original nondefective monoclinic
cell. Different types of oxygen vacancies can hence be classified on the basis
of the calculated ground state properties, electronic structure, and
excitation/emission energies, giving a satisfactory explanation to a range of
experimental observations made on oxygen deficient WO.Comment: Accepted for publication in J. Phys. Chem.
Specifications of view services for GMES Core_003 VHR2 coverage
For the so-called DataWareHouse concept (DWH) within the GMES Initial Operations period 2011-2014, data access management is funded through a Delegation Agreement between the EC and ESA. The Core_003 VHR2 dataset is one of the satellite coverages that are defined as CORE datasets within the DWH with fixed specifications which will be of-fered to a broad range of users and activities. JRC was asked by DG Enterprise to provide technical specifications for the implementation of a view service for the Core_003 datasets as part of the Administrative Arrangement n. 5 between DG Enterprise and JRC. This report provides an overview about different view service types with their specific characteristics and use cases. Since compliance with INSPIRE implementing rules is a goal to be achieved by GMES services, the spe-cific requirements of INSPIRE for view services have been taken into account. The Core_003 datasets have been ana-lysed with regard to their parameters that are important for the inclusion in view services. Based on the results of the analyses, recommendations are given for the implementation of the view services as well as for the data processing and configuration of the Core_003 datasets.JRC.H.6-Digital Earth and Reference Dat
INSPIRE Network Services SOAP Framework
The goal of this document is to provide a definition and rationale for a proposed INSPIRE SOAP framework (SOAP nodes policy, RPC, attachments, WS-I, WSDL) and description of issues and solutions for the specific geospatial domain, for example GML handling in SOAP messages or interfaces definition of the OGC specifications.JRC.H.6-Spatial data infrastructure

Using SPICES for a better service consumption
In this poster we present SPICES (Semantic Platform for the Interaction and Consumption of Enriched Services), a Web based tool that automates the process of consuming a Web service by making use of the semantic annotations that describe them. SPICES supports both traditional WSDL services and RESTful ones and offers end-users the possibility of interacting with them in an easy yet personalised manner, without the need of advanced technical skills -which were traditionally required-, being the complexity that lies underneath hidden to them. SPICES is being developed within the European project SOA4All
SOAP Primer for INSPIRE Discovery and View Services
This document demonstrates the use of the proposed INSPIRE SOAP Framework for the INSPIRE Discovery and View services. This document focuses on the analysis of the WSDL itself (for both the Discovery and View services), explaining its parts and characteristics, as well as on the analysis of SOAP request and response messages, including headers and potential attachments. Moreover, the primer is providing also examples of user scenarios, with specific code samples.JRC.H.6-Spatial data infrastructure
