Estimation of evapotranspiration in the Mu Us Sandland of China
No full textEvapotranspiration (ET) was estimated from 1981–2005 over Wushen County located in the Mu Us Sandland, China, by applying the Advection-Aridity model, which is based on the complementary relationship hypothesis. We used National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR), Moderate Resolution Imaging Spectroradiometer (MODIS), and meteorological data. Our results show that the estimated daily ET was about 4.5% higher than measurements using an Eddy Covariance (EC) system after forcing energy balance closure over an alfalfa field from 22 July 2004 to 23 August 2004. At a regional scale, the estimated monthly ET was about 8.7% lower than measurements using the EC system after forcing energy balance closure over an alfalfa field in August 2004. These results were about 3.0% higher than ET measurements by microlysimeter over sand dunes during June 1988. From 1981 to 2005, the average annual ET and precipitation levels were 287 mm and 336 mm, respectively, in Wushen County. The average annual ET varied from 230 mm in western parts of Wushen County to 350 mm in eastern parts of the county. Both inter-annual and seasonal variations in ET were substantial in Wushen County. The annual ET was 200–400 mm from 1981–2005, and the seasonal pattern of ET showed a single peak distribution. The cumulative ET during the June–September 2004 period was 250 mm, which was 87% of the total annual ET. The annual ET, precipitation, and the maximum Normalized Difference Vegetation Index (NDVI<sub>max</sub>) showed positive correlations temporally and spatially

STEER - D2.1 - Reference use case
No full textSTEER envisages a community-centric digitally-based ecosystem which it refers to as “Social Telemedia” as a cross-breeding of social networks and networked media. According to STEER, the Future Social Telemedia Lifecycle will revolve around media services that user communities can both autonomously build and enjoy exploiting smart tools and specific networking facilities. Hence, the project will investigate the possibilities opened by the creation of an ecosystem where these elements are coordinated to enhance the experiences of their members.To lay the foundation for this work, the present deliverable will introduce a real-life use case that describe the experiences of people that find themselves involved as “producers” and “consumers” of a social telemedia ecosystem. The use case concerns geographically distributed communities of people that automatically gather around an “event”, about which the community members share, retrieve, exchange, and integrate networked media objects that they produce to tell stories from each individual’s perspective.Through this use case, we will be able to show how technologies developed in STEER can facilitate the assessment of the nature of the Future Social Telemedia Lifecycle that revolves around communities, reveal new properties and patterns, create new insights, and explore the synergy between Social Informatics and Networked Media delivery, and its impact on user experiences.While the use case reflects STEER’s vision on future community media service, it is not within the project’s objectives to fully implement the whole set of tools that can make the use case happen in all its aspects. While many of the STEER technologies will provide essential functionalities to the use case, there are also topics that will remain out of the scope of the STEER. For such topics, STEER will however provide outlooks, recommendations and links to related EC projects
STEER: D2.2 STEER requirements and experimental environment architecture
No full textSTEER develops around the concept of innovative social and network-aware media distribution architecture that:*coordinates the effective sharing of media and networking resources among participating users, ensuring scalability, stability and network friendliness,*exploits features and capabilities of modern home gateways, such as caching and transcoding, to limit the cost of media distribution through resource sharing, dynamically adapting media exchanges to the capacity of the underlying networks, reducing service discontinuities and improving the overall Quality of Experience of the customer, and*makes the best usage of information about media object geographic location, social relationships and media object dynamics (e.g., popularity changes) to offer an efficient and personalized social-aware search and recommendation functionality.This document provides a detailed view of the STEER architecture, through the definition of its functional components, their purpose, mutual interactions and the applications that the project plans to develop with them.The document is organized as follows:*Section 1 delineates the structure of the document and the underlying rationale*Section 2 analyses the objectives that the STEER architectures tries to fulfil, expressed as system-level requirements affecting end users behaviour, user devices, home gateways, involved service providers, and STEER applications*Section 3 shows how STEER provides a way of organizing the wide range of raw information collected across various social media networks into a number of complementary, structured databases (or ‘graphs’) whose manipulation allows to achieve a deeper insight of the mutual relationships among user, events and data aggregates. This in turn sets the foundations for optimizing features such as recommendation, caching and media distribution.*Section 4 introduces a short but holistic view of the STEER architectural components and their main interactions*Section 5 describes the STEER components in more detail, explaining their purpose, their functionalities and the research objectives that motivate their usage, with relationship to the requirements set in Section 2.*Section 6 and Section 7 describe how specific STEER components are exploited to implement the STEER Augmented Live Broadcast and Storytelling applications, respectively, and the way they address the use cases described in Deliverable D2.1. The user interfaces for both applications has been defined in Deliverable D2.3
Phase Diagram at Finite Chemical Potentials in the Nambu-Jona-Lasinio Model
No full textWe study the phase diagram of two flavor dense QCD at finite isospin and baryon chemical potentials in the framework of Nambu-Jona-Lasinio model. The system undergoes a crossover from a Bose-Einstein condensate of charged pions to a BCS superfluid with condensed quark-antiquark Cooper pairs when mu(I) increases at mu(B) = 0, and a nonzero baryon chemical potential serves as a mismatch between the pairing species. We observe a gapless pion condensation phase near the quadruple point (mu(I), mu(B)) = (m(pi), M-N-1.5m(pi)) where m(pi), M-N are the vacuum masses of pions and nucleons, respectively. At very large isospin chemical potential, mu(I) > 6.36m(pi), an inhomogeneous LOFF superfluid phase appears in a window of mu(B). Between the gapless and the LOFF phases, the pion superfluid phase and the normal quark matter phase are connected by a first order phase transition.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000302957500023&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, Atomic, Molecular & ChemicalCPCI-S(ISTP)
SNR-degraded 129Xe ventilation MRI for the comparison of quantification methods
No full textDriven by the need to quantify these functional MR images robustly, multiple classifiers have been proposed to determine ventilation defect percentages as well as other ventilated clusters. However, these various methods have yet to be harmonized, which creates a barrier to deploying quantitative 129Xe MRI for multi-center studies. Here, we seek to help the pulmonary functional MRI community standardize its analysis methods that can be used going forward. To facilitate this endeavor we have made the images, as well as their SNR-degraded versions publicly available
