    Article
    Open Access
    In this letter, a three-dimensional (3-D) printed compact ultrawideband (UWB) extended gap ridge horn (EGRH) antenna designed to be used for biological measurements of the human body is described. The operational frequency ...

  • Chinese-Catalan: A neural machine translation approach based on pivoting and attention mechanisms 

    Ruiz Costa-Jussà, Marta; Casas Manzanares, Noé; Escolano Peinado, Carlos; Rodríguez Fonollosa, José Adrián (2019-01-01)
    Article
    Open Access
    This article innovatively addresses machine translation from Chinese to Catalan using neural pivot strategies trained without any direct parallel data. The Catalan language is very similar to Spanish from a linguistic point ...

  • A 125-143-GHz frequency-reconfigurable BiCMOS compact LNA using a single RF-MEMS switch 

    Heredia, Julio; Ribó i Pal, Miquel; Pradell i Cara, Lluís; Wipf, Selin Tolunay; Göritz, Alexander; Wipf, Christian; Kaynak, Mehmet (2019-05-01)
    Article
    Open Access
    In this letter, a 125-143-GHz frequency-reconfigurable BiCMOS compact low-noise amplifier (LNA) is presented for the first time. It consists of two cascode stages and was fabricated using a 0.13-µm SiGe:C BiCMOS process, ...

  • An efficient RAN slicing strategy for a heterogeneous network with eMBB and V2X services 

    Resin Albonda, Haider D.; Pérez Romero, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)
    Article
    Open Access
    Emerging 5G wireless technology will support services and use cases with vastly heterogeneous requirements. Network slicing, which allows composing multiple dedicated logical networks with specific functionality running ...

  • A cloud-enabled small cell architecture in 5G networks for broadcast/multicast services 

    kourtis, Michail-Alexandros; Blanco, Begoña; Pérez Romero, Jordi; Makris, Dimitris; McGrath, Michael J.; Xilouris, George; Munaretto, Daniele; Solozabal, Ruben; Sanchoyerto, Aitor; Giannoulakis, Ioannis; Kafetzakis, Emmanouil; Riccobene, Vincenzo; Jimeno, Elisa; Kourtis, Anastasios; Ferrús Ferré, Ramón Antonio; Liberal, Fidel; Koumaras, Harilaos; Kostopoulos, Alexandros; Chochliouros, Ioannis (2019-06-01)
    Article
    Open Access
    The evolution of 5G suggests that communication networks become sufficiently flexible to handle a wide variety of network services from various domains. The virtualization of small cells as envisaged by 5G, allows enhanced ...

  • Hong-Ou-Mandel interferometry on a biphoton beat note 

    Chen, Yuanyuan; Fink, Matthias; Steinlechner, Fabian; Pérez Torres, Juan; Ursin, Rupert (2019-05-24)
    Article
    Open Access
    Hong-Ou-Mandel interference, the fact that identical photons that arrive simultaneously on different input ports of a beam splitter bunch into a common output port, can be used to measure optical delays between different ...

  • FCC physics opportunities: future circular collider conceptual design report volume 1 

    Abada, A.; Abbrescia, M.; AbdusSalam, S. S.; O'Callaghan Castellà, Juan Manuel (Springer, 2019-06-05)
    Article
    Open Access
    We review the physics opportunities of the Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. We describe the measurement capabilities of each FCC component, addressing the study of electroweak, ...

  • Metastability of quantum droplet clusters 

    Kartashov, Yaroslav V.; Malomed, Boris A.; Torner Sabata, Lluís (American Institute of Physics (AIP), 2019-05-14)
    Article
    Open Access
    We show that metastable ring-shaped clusters can be constructed from two-dimensional quantum droplets in systems described by the Gross-Pitaevskii equations augmented with Lee-Huang-Yang quantum corrections. The clusters ...
