    • Spontaneous eye-movements in neutral and emotional gaze-cuing: An eye-tracking investigation 

      McCrackin, Sarah D; Soomal, Sarika K; Patel, Payal; Itier, Roxane J. (Elsevier, 2019-04)
      Our attention is spontaneously oriented in the direction where others are looking. This attention shift manifests as faster responses to peripheral targets when they are gazed at by a central face instead of gazed away ...
    • Spontaneous Tilting Transition in Liquid-Crystalline Polymer Brushes 

      Blaber, Steven; Abukhdeir, Nasser Mohieddin; Matsen, Mark (2019)
      The equilibrium phase behavior of main-chain liquid-crystalline polymer brushes in good solvent is investigated using self-consistent field theory. The calculation assumes semi-dilute brushes, where the grafting density ...
    • Spontaneous weaving: 3D porous PtCu networks with ultrathin jagged nanowires for highly efficient oxygen reduction reaction

      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 ...
    • Stability of Connected Autonomous Vehicle Networks with Commensurate Time Delays 

      Al-Darabsah, Isam; Al Janaideh, Mohammad; Campbell, Sue Ann (IEEE, 2021-05)
      In this paper, we study the stability of Connected Autonomous Vehicle Networks (CAVN) with commensurate time delays under the assumption that communication time delays increase as the distance between the vehicles increases. ...
    • 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, bifurcation and phase-locking of time-delayed excitatory-inhibitory neural networks 

      Ryu, Hwayeon; Campbell, Sue Ann (AIMS Press, 2020-11)
      We study a model for a network of synaptically coupled, excitable neurons to identify the role of coupling delays in generating different network behaviors. The network consists of two distinct populations, each of which ...
    • 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 ...

    • 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 ...
