  Parcet, Maria-Antònia; Adrián Ventura, Jesús; Costumero, Víctor; Ávila, César (Frontiers, 2020)

  Sensitivity to reward is a personality trait that predisposes a person to several addictive behaviors, including the presence of different risky behaviors that facilitates uncontrolled eating. However, the multifactorial ...
• Challenges for coonnecting citizens and smart cities: ICT, e-governance and blockchain

  Oliveira, Thays A.; Oliver Riera, Miquel; Ramalhinho-Lourenço, Helena (MDPI, 2020)

  Global brain states are frequently placed within a unidimensional continuum by correlational studies, ranging from states of deep unconsciousness to ordinary wakefulness. An alternative is their multidimensional and ...
• Dynamic coupling of whole-brain neuronal and neurotransmitter systems

  Kringelbach, Morten L.; Cruzat, Josephine; Cabral, Joana R. B.; Moos Knudsen, Gitte; Carhart Harris, Robin; Whybrow, Peter C.; Logothetis, N.; Deco, Gustavo (National Academy of Sciences, 2020)

  Remarkable progress has come from whole-brain models linking anatomy and function. Paradoxically, it is not clear how a neuronal dynamical system running in the fixed human anatomical connectome can give rise to the rich ...
• Obey or play: asymptotic equivalence of slotted aloha with a game theoretic contention model

  Barceló Vicens, Jaume; Inaltekin, Hazer; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2011)

  Contention control is an important means to mitigate adverse affects of multiple access interference on transmitted data packets in wireless communication networks. Most practical contention control mechanisms, e.g., IEEE ...
• On the performance of packet aggregation in IEEE 802.11ac MU-MIMO WLANs

  Bellalta, Boris; Barceló Vicens, Jaume; Staehle, Dirk; Vinel, Alexey; Oliver Riera, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2012)

  Multi-user spatial multiplexing combined with packet aggregation can significantly increase the performance of Wireless Local Area Networks (WLANs). In this letter, we present and evaluate a simple technique to perform ...
• Performance optimization of multiple interconnected heterogeneous sensor networks via collaborative information sharing

  Pal, Sougata; Oechsner, Simon; Bellalta, Boris; Oliver Riera, Miquel (IOS Press, 2013)

  Interconnecting multiple sensor networks is a relatively new research field which has emerged in the Wireless Sensor Network domain. Wireless Sensor Networks (WSNs) have typically been seen as logically separate, and few ...
• An approximate queueing model for multi-rate multi-user MIMO systems

  Bellalta, Boris; Daza, Vanesa; Oliver Riera, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2011)

• A flexible machine-learning-aware architecture for future WLANs

  Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders; Ram, Vishnu (Institute of Electrical and Electronics Engineers (IEEE), 2020)

  Lots of hopes have been placed on machine learning (ML) as a key enabler of future wireless networks. By taking advantage of large volumes of data, ML is expected to deal with the ever-increasing complexity of networking ...
• Cortical state transitions and stimulus response evolve along stiff and sloppy parameter dimensions, respectively

  Ponce-Alvarez, Adrián; Mochol, Gabriela; Hermoso Mendizábal, Ainhoa; De la Rocha, Jaime; Deco, Gustavo (eLife, 2020)
