  • Mode-cleaning in antisymmetrically modulated non-Hermitian waveguides 

    Akhter, Mohammad Nayeem; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis (2024-01-12)
    Article
    Accés obert
    We demonstrate all-optical spatial mode-cleaning in non-Hermitian waveguides. The effect is accounted by a unidirectional coupling among the modes resulting from a simultaneous modulation of the refractive index and the ...

    Accés restringit per política de l'editorial
    KRAS oncogenes are the largest family of mutated RAS isoforms, participating in about 30% of all cancers. Due to their paramount medical importance, enormous effort is being devoted to the development of inhibitors using ...
  • Connection between mechanical relaxation and equilibration kinetics in a high-entropy metallic glass 

    Duan, Yajuan; Nabahat, Mehran; Tong, Yu; Ortiz Membrado, Laia; Jiménez Piqué, Emilio; Zhao, Kun; Wang, Yun-Jiang; Yang, Yong; Wada, Takeshi; Kato, Hidemi; Pelletier, J. M.; Qiao, Jichao; Pineda Soler, Eloi (American Institute of Physics (AIP), 2024-02-02)
    Article
    Accés obert
    The slow transition from an out-of-equilibrium glass towards a supercooled liquid is a complex relaxation phenomenon. In this Letter, we study the correlation between mechanical relaxation and equilibration kinetics in a ...

    A comprehensive analysis of the unsteady flow dynamics past the 30P30N three-element high lift wing is performed by means of large eddy simulations at different angles of attack (AoA=5°, 9°, and 23°) and at a Reynolds ...
  • Permutation entropy-based characterization of speckle patterns generated by semiconductor laser light 

    Tirabassi, Giulio; Duque Gijón, María; Tiana Alsina, Jordi; Masoller Alonso, Cristina (2023-12)
    Article
    Accés obert
    Semiconductor lasers with optical feedback are stochastic nonlinear systems that can display complex dynamics and abrupt changes when their operation conditions change. Even very small changes can lead to large variations ...

    Álvarez Galera, Edgar; Laria, Daniel; Batet Miracle, Lluís; Martí Rabassa, Jordi (2024-02)
    Article
    Accés obert
    The determination of the solubility of helium in liquid lithium and in lead-lithium eutectic systems is of crucial importance for the assessment of the reliability, safety and efficiency of future nuclear reactor plants ...
  • In silico design of a lipid-like compound targeting KRAS4B-G12D through non-covalent bonds 

    Lu, Huixia; Hu, Zheyao; Faraudo, Jordi; Martí Rabassa, Jordi (2023-11-21)
    Article
    Accés obert
    One of the most common drivers in human cancer is the peripheral membrane protein KRAS4B, able to promote oncogenic signalling. To signal, oncogenic KRAS4B not only requires a sufficient nucleotide exchange, but also needs ...
  • Lyapunov exponents and extensivity of strongly coupled chaotic maps in regular graphs 

    Gancio Vázquez, Juan; Rubido, Nicolas (Elsevier, 2024-01-01)
    Article
    Accés obert
    n Thermodynamics and Statistical Physics, a system’s property is extensive when it grows with the system size. When it happens, the system can be decomposed into separate components, which has been done in many systems ...
  • Phase separation in binary Bose mixtures at finite temperature 

    Spada, Gabriele; Parisi, L.; Pascual López, Gerard; Parker, Nicholas G.; Billam, Thomas P.; Pilati, Sebastiano; Boronat Medico, Jordi; Giorgini, Stefano (2023-10-18)
    Article
