    • Almost sharp nonlinear scattering in one-dimensional born-infeld equations arising in nonlinear electrodynamics 
      Alejo, Miguel; Muñoz, Claudio (American Mathematical Society, 2018)
      We study decay of small solutions of the Born-Infeld equation in 1+1 dimensions, a quasilinear scalar field equation modeling nonlinear electromagnetism, as well as branes in String theory and minimal surfaces in Minkowski ...
    • Dispersive estimates for rational symbols and local well-posedness of the nonzero energy NV equation. II 
      Kazeykina, Anna; Muñoz, Claudio (Academic Press INC Elsevier Science, 2018)
      We continue our study on the Cauchy problem for the two-dimensional Novikov-Veselov (NV) equation, integrable via the inverse scattering transform for the two dimensional Schrodinger operator at a fixed energy parameter. ...
    • Occupational Exposure to Polycyclic Aromatic Hydrocarbons: A Cross-Sectional Study in Bars and Restaurants ... 
      Muñoz, Claudio; Droppelmann, Andrea; Erazo Bahamondes, Marcia; Aceituno, Paulina; Orellana Pozo, Cecilia; Parro Fluxa, Javiera; Mesías Monsalve, Stephanie; Marchetti Pareto, Nella; Navas Acien, Ana; Iglesias Álamos, Verónica; Navas Acie (Wiley, 2016-10)
      Objective To evaluate indoor polycyclic aromatic hydrocarbon (PAH) concentrations in bars and restaurants and identify the main determinants of airborne PAH concentrations. Methods This study included 57 bars/restaurants ...
    • On the variational structure of breather solutions II: Periodic MKDV equation 
      Alejo, Miguel A.; Muñoz, Claudio; Palacios, José M. (Texas State University, 2017)
      We study the periodic modified KdV equation, where a periodic in space and time breather solution is known from the work of Kevrekidis et al. [19]. We show that these breathers satisfy a suitable elliptic equation, and we ...
    • Review on the Stability of the Peregrine and Related Breathers 
      Alejo, Miguel A.; Fanelli, Luca; Muñoz, Claudio (Frontiers Media, 2020)
      In this note, we review stability properties in energy spaces of three important nonlinear Schrodinger breathers: Peregrine, Kuznetsov-Ma, and Akhmediev. More precisely, we show that these breathers are unstable according ...
    • Scattering in the Energy Space for Boussinesq Equations 
      Muñoz, Claudio; Poblete, Felipe; Pozo, Juan (Springer, 2018-07)
      In this note we show that all small solutions in the energy space of the generalized 1D Boussinesq equation must decay to zero as time tends to infinity, strongly on slightly proper subsets of the space-time light cone. ...
    • Secondhand tobacco smoke exposure and pulmonary function: a cross sectional study among non smoking employees ... 
      Parro, Javiera; Aceituno, Paulina; Droppelmann, Andrea; Mesias, Sthepanie; Muñoz, Claudio; Marchetti Pareto, Nella; Iglesias, Verónica (BMJ Publishing Group, 2017)
      Introduction The workplace remains a significant source of secondhand smoke (SHS) exposure. This pollutant is known to be associated with respiratory and cardiovascular problems, but its effects on specific pulmonary ...
    • The Akhmediev breather is unstable 
      Alejo, Miguel A.; Fanelli, Luca; Muñoz, Claudio (Springer, 2019)
      In this note, we give a rigorous proof that the NLS periodic Akhmediev breather is unstable. The proof follows the ideas in Muñoz (Proyecciones (Antofagasta) 36(4):653–683, 2017), in the sense that a suitable modification ...
