  • Singular cotangent models in fluids with dissipation 

    Coquinot, Baptiste; Mir Garcia, Pau; Miranda Galcerán, Eva (2023-04)
    Article
    Open Access
    In this article we analyze several mathematical models with singularities where the classical cotangent model is replaced by a -cotangent model. We provide physical interpretations of the singular symplectic geometry ...
  • Analysis of the epidemiological dynamic of monkeypox from 15th May to 31st August 2022 

    Perramon Malavez, Aida; Álvarez Lacalle, Enrique; Català Sabaté, Martí; López de Rioja, Víctor; Alonso Muñoz, Sergio; Prats Soler, Clara; López Codina, Daniel (2022-09-01)
    Article
    Open Access
    We show that in all countries with more than 1000 monkeypox cases at the end of August 2022, the evolution of the total number of cases is described by the Gompertz growth model. Although the data collection has many ...
  • Low-energy scattering parameters: A theoretical derivation of the effective range and scattering length for arbitrary angular momentum 

    Pera i Ferreruela, Jordi; Boronat Medico, Jordi (AMER INST PHYSICS, 2023-02-01)
    Article
    Restricted access - publisher's policy
    The most important parameters in the study of low-energy scattering are the s-wave and p-wave scattering lengths and the s-wave effective range. We solve the scattering problem and find two useful formulas for the scattering ...
  • Abrupt transition from low-coherence to high-coherence radiation in a semiconductor laser with optical feedback 

    Duque Gijón, María; Masoller Alonso, Cristina; Tiana Alsina, Jordi (2023-01-19)
    Article
    Open Access
    Semiconductor lasers are very sensitive to optical feedback. Although it is well known that coherent feedback lowers the threshold of the laser, the characteristics of the transition from low-coherence radiation—dominated ...
  • Stabilisation of spatially periodic states by non-Hermitian potentials 

    Benadouda Ivars, Salim; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis (2023-03)
    Article
    Restricted access - publisher's policy
    We uncover new families of stable periodic solutions by the introduction of non-Hermitian potentials in the universal complex Ginzburg–Landau equation. We perform a comprehensive analysis on the dynamics and stability of ...
  • Non-Hermitian control of optical turbulence in systems with fractional dispersion 

    Benadouda Ivars, Salim; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis (Elsevier, 2022-12-01)
    Article
    Open Access
    We show an efficient mechanism to control optical turbulence in systems with different dispersion laws, including parabolic, sub-diffractive, hyper-diffractive or general fractional dispersion. The method is based on the ...
  • The Neutron Star Population in M28: A Joint Chandra/GBT Look at Pulsar Paradise 

    Vurgun, Eda; Linares Alegret, Manuel; Ransom, Scott; Papitto, Alessandro; Bogdanov, Slavko; Bozzo, Enrico; Rea, Nanda; García Senz, Domingo; Freire, Paulo; Stairs, Ingrid (Institute of Physics (IOP), 2022-12-01)
    Article
    Open Access
    We present the results of a deep study of the neutron star (NS) population in the globular cluster M28 (NGC 6626), using the full 330 ks 2002–2015 ACIS data set from the Chandra X-ray Observatory and coordinated radio ...
  • Intrinsic correlation between the fraction of liquidlike zones and the beta relaxation in high-entropy metallic glasses 

    Duan, Yajuan; Zhang, Langting; Qiao, J. C.; Wang, Yun-Jiang; Yang, Y.; Wada, T.; Kato, Hidemi; Pelletier, J. M.; Pineda Soler, Eloi; Crespo Artiaga, Daniel (American Institute of Physics (AIP), 2022-10-21)
    Article
    Open Access
    Lacking the structural information of crystalline solids, the origin of the relaxation dynamics of metallic glasses is unclear. Here, we report the evolution of stress relaxation of high-entropy metallic glasses with ...
  • Self-sustainment of coherent structures in counter-rotating Taylor-Couette flow 

    Wang, Baoying; Ayats, Roger; Deguchi, Kengo; Mellibovsky Elstein, Fernando; Meseguer Serrano, Álvaro (Cambridge University Press, 2022-11-25)
    Article
    Restricted access - publisher's policy
    We investigate the local self-sustained process underlying spiral turbulence in counter-rotating Taylor–Couette flow using a periodic annular domain, shaped as a parallelogram, two of whose sides are aligned with the ...
  • Effect of Si and B on the electrochemical behavior of FeCoNiCr-based high-entropy amorphous alloys 

    Panahi, Seyedeh Leila; Bruna Escuer, Pere; Pineda Soler, Eloi (Multidisciplinary Digital Publishing Institute (MDPI), 2022-12-13)
    Article
    Open Access
    The ability to produce high-entropy alloys with an amorphous structure, so-called high-entropy metallic glasses (HEMGs), offers the possibility to produce new compositions with good mechanical properties and resistance to ...
  • Multisystem inflammatory syndrome in children in western countries: decreasing incidence as the pandemic progresses? An observational multicenter international cross-sectional study 

    Buonsenso, Danilo MD; Perramon Malavez, Aida; Català Sabaté, Martí; Torres Cepeda, Juan P.; Camacho Moreno, Germán; Rojas Solano, Mariela; Ulloa Gutiérrez, Rolando; amacho Badilla, Kattia; Pérez Corrales, Cristian; Cotugno, Nicola; Yamazaki Nakashimada, Marco; Estripeaut Calderón, Dora; Buddingh, Emilie Pauline; von Asmuth, Erik; van Rossum, Annemarie; Rivière, Jacques G.; Pino Ramirez, Rosa Maria; Prats Soler, Clara (Lippincott Williams & Wilkins, 2022-09-12)
    Article
    Open Access
    Multisystemic inflammatory syndrome temporally associated with SARS-CoV-2 infection in children (MIS-C) has been reported worldwide.1–7 The case definition of MIS-C has been estab- lished by different institutions and ...
  • Delayed elasticity of metallic glasses: Loading time and temperature dependences of the anelastic relaxation 

    Nabahat, Mehran; Amini, Narges; Pineda Soler, Eloi; Yang, Fan; Qiao, Jichao; Ruta, Beatrice; Crespo Artiaga, Daniel (American Physical Society (APS), 2022-12-09)
    Article
    Open Access
    One of the hallmarks of disordered matter is the large amplitude of the anelastic deformation, i.e., the fraction of reversible deformation that is not instantaneously recovered after the release of load but is delayed in ...
