• Generalized Cornu-type spirals and their Darboux parametric deformations 

      Rosu Barbus, Haret-Codratian; Mancas, Stefan C; Hsieh, Chun-Chung (Elsevier, 2019)
      "We generalize the Fresnel integrals and introduce a class of spirals F-n, which contains the Cornu spiral as the case F-2. Their Darboux parametric deformations are also investigated. The F-3 spiral and some of its Darboux ...
    • Radius evolution for bubbles with elastic shells 

      Mancas, Stefan C; Rosu Barbus, Haret-Codratian; Hsieh, Chun-Chung (Elsevier, 2021)
      "We present an analysis of an extended Rayleigh–Plesset (RP) equation for a three dimensional cell of microorganisms such as bacteria or viruses in some liquid, where the cell membrane in bacteria or the envelope (capsid) ...
    • Superfluid Rayleigh–Plesset extension of FLRW cosmology 

      Rosu Barbus, Haret-Codratian; Mancas, Stefan C; Hsieh, Chun-Chung (Elsevier, 2021)
      "Guided by the analogy with the Rayleigh–Plesset dynamics of multielectron bubbles in superfluid He-4, we consider the cosmological FLRW evolution equation with additional cubic and sixth powers of the inverse of the scale ...
