Conductivities consistent with Birkeland currents in the AMPERE‐driven TIE‐GCM
No full textThe Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE)
satellite mission has offered for the first time global snapshots of the geomagnetic field-aligned currents
with unprecedented space and time resolution, thus providing an opportunity to feed an acknowledged
first-principles model of the Earth’s upper atmosphere such as the National Center for Atmospheric Research
Thermosphere-Ionosphere-Electrodynamics General Circulation Model (NCAR TIE-GCM). In the first step,
Marsal et al. (2012) used AMPERE data in the current continuity equation between the magnetosphere and
the ionosphere to drive the TIE-GCM electrodynamics. In the present work, ionospheric conductivities have
been made consistent with enhanced upward field-aligned currents, which are assumed to correspond to
electrons plunging as a result of downward acceleration by electric fields built up along the geomagnetic
field lines. The resulting conductance distribution is reasonably commensurate with an independent model
that has tried to quantify the ionizing effect of precipitating particles onto the auroral ionosphere. On the
other hand, comparison of geomagnetic observatory data with the ground magnetic variations output by the
model only shows a modest improvement with respect to our previous approach

Yield and berry composition of 'Tempranillo' grapevines exposed to deficit irrigation applied at different phenological stages
No full textThe correct use of deficit irrigation (DI) in viticulture for wine production represent an effective tool to improve berry composition at harvest. However, these effects are strongly dependent on the phenological stage when DI is applied and on the level of water stress induced. If water stress is too severe, berry composition is negatively affected. Severe water stress conditions can easily occur in vineyards located in dry areas when irrigation is withhold. Hence, the aim of this experiment was to study how withdrawing irrigation at two different phenological stages affects fruit yield and berry composition in a dry region. The experiment was carried out in Raimat (Lleida, Catalonia, Spain) on 'Tempranillo' grapevines. The experimental design was a complete randomized block design with three treatments and four blocks. Treatments were the following: a DI treatment in which vines received 0% of calculated evapotranspiration (ETc) between fruit set and veraison, whereas 100% of ETc was replaced with irrigation during the other phenological stages (hereafter PRE-DI treatment); a DI treatment in which vines received 0% of ETc between veraison and harvest, whereas 100% of ETc was replaced with irrigation during the other phenological stages (hereafter POST-DI treatment); a control treatment in which vines received 100% of ETc throughout the growing season (hereafter C treatment). Between fruit set and harvest, PRE-DI and POST-DI treatments allowed to save 41 and 45% of water applied with irrigation. Both DI treatments induced moderate water stress conditions (midday stem water potential decreased down to values between -1.5 and -1.3 MPa) in the phenological stages when irrigation was withhold. Harvest date was anticipated by PRE-DI treatment compared to POST-DI and C vines. PRE-DI induced a decrease in berry growth and fruit yield at harvest. POST-DI did not affect berry anthocyanin concentration at harvest
Towards Machine-Learning-Based 5G and Beyond Intelligent Networks: The MARSAL Project Vision has been updated
No full text5G mobile networks will be soon available to handle all types of applications and to provide service to massive numbers of users. In this complex and dynamic network ecosystem, end-to-end performance analysis and optimization will be key features to effectively manage the diverse requirements imposed by multiple vertical industries over the same shared infrastructure. To enable such a vision, the MARSAL project targets the development and evaluation of a complete framework for the management and orchestration of network resources in 5G and beyond, by utilizing a converged optical-wireless network infrastructure in the access and fronthaul/midhaul segments. At the network design domain, MARSAL targets the development of novel cell-free based solutions by exploiting the application of the distributed cell-free concept and of the serial fronthaul approach, while contributing innovative functionalities to the O-RAN project. In parallel, in the fronthaul/midhaul segments MARSAL aims to radically increase the flexibility of optical access architectures via different levels of fixed-mobile convergence. At the network and service management domain, the design philosophy of MARSAL is to exploit novel ML-based algorithms of both edge and midhaul DCs, by incorporating the Virtual Elastic DataCenters/Infrastructures paradigm. Finally, at the network security domain, MARSAL aims to introduce mechanisms that provide privacy and security to application workload and data, targeting to allow applications and users to maintain control over their data, while AI and and Blockchain technologies will be developed in order to guarantee a secured multi-tenant slicing environment
