Second Order Gauge Theory [PDF]
Annals of Physics, 2007 A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength $G=\partial F+fAF$ arises besides the one of the first order treatment, $F=\partial A-\partial A+fAA$.

Second-Order Footsteps Illusions
i-Perception, 2015 In the “footsteps illusion”, light and dark squares travel at constant speed across black and white stripes. The squares appear to move faster and slower as their contrast against the stripes varies.

Second-Order Finite Automata [PDF]
Theory of Computing Systems, 2020 AbstractTraditionally, finite automata theory has been used as a framework for the representation of possibly infinite sets of strings. In this work, we introduce the notion of second-order finite automata, a formalism that combines finite automata with ordered decision diagrams, with the aim of representing possibly infinitesets of setsof strings. Our

Second-order Darboux displacements [PDF]
Journal of Physics A: Mathematical and General, 2003 The potentials for a one dimensional Schroedinger equation that are displaced along the x axis under second order Darboux transformations, called 2-SUSY invariant, are characterized in terms of a differential-difference equation. The solutions of the Schroedinger equation with such potentials are given analytically for any value of the energy.

Second-Order Reversed Phi [PDF]
Perception & Psychophysics, 1999 Abstract A second-order reversed-phi stimulus is composed of moving features (areas filled with texture) whose overall amount of texture-contrast is reversed between successive frames. In peripheral vision, the stimulus is perceived as moving in the reversed direction (opposite to the feature displacement).

Second-order resummed thermodynamic perturbation theory for central-force associating potential: Multi-patch colloidal models [PDF]
, 2013 We propose a second-order version of the resummed thermodynamic perturbation theory for patchy colloidal models with arbitrary number of multiply bondable patches.

Exponential Time Differencing Algorithm for Pulse-Coupled Hodgkin-Huxley Neural Networks
Frontiers in Computational Neuroscience, 2020 The exponential time differencing (ETD) method allows using a large time step to efficiently evolve stiff systems such as Hodgkin-Huxley (HH) neural networks.
