  • Convexity and symmetry of central configurations in the five-body problem: Lagrange plus two 

    Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Fernandes, Antonio Carlos; Vidal Díaz, Claudio (2021-07-10)
    Article
    Restricted access - publisher's policy
    We study convexity and symmetry of central configurations in the five body problem when three of the masses ara located at the vertices of an equilateral triangle, that we call Lagrange plus two central configurations. ...
  • Engineering self-organized criticality in living cells 

    Vidiella, Blai; Guillamon Grabolosa, Antoni; Sardanyes, Josep; Maull Miquel, Víctor; Pla Mauri, Jordi; Conde Pueyo, Núria; Solé, Ricard (2021-12-01)
    Article
    Open Access
    Complex dynamical fluctuations, from intracellular noise, brain dynamics or computer traffic display bursting dynamics consistent with a critical state between order and disorder. Living close to the critical point has ...
  • Bivalent chromatin as a therapeutic target in cancer: an in silico predictive approach for combining epigenetic drugs 

    Alarcón, Tomás; Sardanyes, Josep; Guillamon Grabolosa, Antoni (Public Library of Science (PLOS), 2021-06-01)
    Article
    Open Access
    Tumour cell heterogeneity is a major barrier for efficient design of targeted anti-cancer therapies. A diverse distribution of phenotypically distinct tumour-cell subpopulations prior to drug treatment predisposes to ...
  • Central configurations in the five-body problem: rhombus plus one 

    Lino Cornelio, J.; Alvarez Ramírez, Martha; Cors Iglesias, Josep Maria (2021-05-20)
    Article
    Open Access
    We show the existence of central configurations in the planar five-body problem where four bodies are located at the vertices of a rhombus, called rhombus plus one central configurations. Concretely we prove analytically ...
  • Ageing of an oscillator due to frequency switching 

    Bonet Revés, Carles; Jeffrey, Mike R.; Martín de la Torre, Pablo; Olm Miras, Josep Maria (2021-11-01)
    Article

    If an oscillator is driven by a force that switches between two frequencies, the dynamics it exhibits depends on the precise manner of switching. Here we take a one-dimensional oscillator and consider scenarios in which ...
  • SARS-CoV-2 transmission in students of public schools of Catalonia (Spain) after a month of reopening 

    Llupià, Anna; Borràs Santos, Alícia; Utzet Sadurní, Mireia; Guinovart Florensa, Caterina; Moriña, David; Puig Sadurní, Joaquim (Public Library of Science (PLOS), 2021-05-12)
    Article
    Open Access
    SARS-CoV-2 transmission within schools and its contribution to community transmission are still a matter of debate. Methods A retrospective cohort study in all public schools in Catalonia was conducted using publicly ...
  • Still using MS Excel? Implementation of the WHO Go.Data software for the COVID-19 contact tracing 

    Llupià, Anna; García Basteiro, Alberto L.; Puig Sadurní, Joaquim (2020-05-08)
    Article

  • Phase-locked states in oscillating neural networks and their role in neural communication 

    Pérez Cervera, Alberto; Martínez-Seara Alonso, M. Teresa; Huguet Casades, Gemma (2020-01-01)
    Article
    Open Access
    The theory of communication through coherence (CTC) proposes that brain oscillations reflect changes in the excitability of neurons, and therefore the successful communication between two oscillating neural populations ...
  • Three-dimensional Lotka–Volterra systems with 3:-1:2-resonance 

    Aziz, Waleed; Christopher, Colin; Llibre Saló, Jaume; Pantazi, Chara (2021-08)
    Article
    Open Access
    We study the local integrability at the origin of a nine-parameter family of three-dimensional Lotka–Volterra differential systems with (3:- 1:2)-resonance. We give necessary and sufficient conditions on the parameters of ...
  • Global phase-amplitude description of oscillatory dynamics via the parameterization method 

    Pérez Cervera, Alberto; Martínez-Seara Alonso, M. Teresa; Huguet Casades, Gemma (Institute of Physics (IOP), 2020-08-01)
    Article
    Open Access
    In this paper, we use the parameterization method to provide a complete description of the dynamics of an n-dimensional oscillator beyond the classical phase reduction. The parameterization method allows us, via efficient ...
  • Analytical and numerical results on families of n-ejection-collision orbits in the RTBP 

    Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2020-11-01)
    Article
    Restricted access - publisher's policy
    In the planar RTBP with mass ratio µ we regularise the singularity at one of the primaries by means of Levi-Civita’s transformation in a rotating frame. We solve the variational equations in a neighbourhood of the ...
  • Change in gap perception within current practices in assessing students learning mathematics 

    Cellmer, Anna; Serrat Piè, Carles; Bruguera Padró, Maria Montserrat; Pantazi, Chara; Estela Carbonell, M. Rosa; Bocanet, Vlad I.; Brown, Ken; Uukkivi, Anne; Soares, Filomena; Feniser, Cristina; Serdean, Florina M.; Safiulina, Elena; Kelly, Gerald; Cymerman, Joanna; Kierkosz, Igor; Volodymyr, Sushch; Latõnina, Marina; Labanova, Oksana; Lopes, Ana Paula (2021-04-17)

    Open Access
    The COVID pandemic has touched many aspects of everyone’s life. Education is one of the fields greatly affected by it, as students and teachers were forced to move online and quickly adapt to the online environment. ...
