      We report a simple and efficient surfactant-free method to prepare 3D porous PtCu networks with ultrathin jagged nanowires and controllable composition. The morphological evolution and the influential effects of the important ...
    • Stability analysis by contraction principle for impulsive systems with infinite delays 

      Liu, Xinzhi; Ramirez, Cesar (Elsevier, 2020-03)
      This paper studies a class of quasi-linear impulsive systems of functional differential equations with infinite time delay. By employing the contraction principle, several criteria on uniform stability and asymptotic ...
    • Stability and Well-posedness of a Nonlinear Railway Track Model 

      Edalatzadeh, M. Sajjad; Morris, Kirsten (Institute of Electrical and Electronics Engineers, 2018-06-22)
      Railway tracks rest on a foundation known for exhibiting nonlinear viscoelastic behavior. Railway track deflections are modeled by a semilinear partial differential equation. This paper studies the stability of solutions ...
    • A Stability Theorem for Matchings in Tripartite 3-Graphs 

      Haxell, Penny; Narins, Lothar (Cambridge University Press, 2018-04-02)
      It follows from known results that every regular tripartite hypergraph of positive degree, with n vertices in each class, has matching number at least n/2. This bound is best possible, and the extremal configuration is ...
    • Stability-based fire resistance duration of unbraced steel frames 

      Ma, Terence; Xu, Lei (Journal of Structural Fire Engineering, 2020)
      Purpose The collapse of a structure resulting from the instability of steel frames due to fire is the worst failure mode to consider in fire-structural engineering, and should be avoided. The purpose of this paper is to ...
    • A Stable Lipid/TiO2 Interface with Headgroup Inversed Phosphocholine and a Comparison with SiO2 

      Wang, Feng; Liu, Juewen (American Chemical Society, 2015-09-16)
      Zwitterionic phosphocholine (PC) lipids are highly biocompatible, representing a major component of the cell membrane. A simple mixing of PC liposomes and silica (SiO2) surface results in liposome fusion with the surface ...
    • Standalone Tensile Testing of Thin Film Materials for MEMS/NEMS Applications 

      Tajik, Arash; Jahed, Hamid (In Tech, 2012-03-28)
      The microelectronics industry has been consistently driven by the scaling roadmap, colloquially referred to as the Moore’s law. Consequently, during the past decades, integrated circuits have scaled down further. This ...

    • Statistical Issues in Modeling Chronic Disease in Cohort Studies 

      Cook, Richard J.; Lawless, Jerald F. (Springer, 2014)
