Unpacking “For Reasons of Symmetry”: Two Categories of Symmetry Arguments
Unpacking “For Reasons of Symmetry”: Two Categories of Symmetry Arguments
Hermann Weyl succeeded in presenting a consistent overarching analysis that accounts for symmetry in (1) material artifacts, (2) natural phenomena, and (3) physical theories. Weyl ...
Determination of symmetry relations between higher order material constants for the study of nonlinear acoustic properties of piezoelectric crystals of any symmetry class
Determination of symmetry relations between higher order material constants for the study of nonlinear acoustic properties of piezoelectric crystals of any symmetry class
Each crystal is invariant under a given point symmetry operation. This results in relations between the different material property constants, such as second order elastic constant...

Training Pi-Sigma Network by Online Gradient Algorithm with Penalty for Small Weight Update
A pi-sigma network is a class of feedforward neural networks with product units in the output layer. An online gradient algorithm is the simplest and most often used training metho...

Symmetry is sexy: reply to Hodgson's ‘Symmetry and humans’
In his contribution to the Antiquity debate over the viability of Kohn and Mithen's 'Sexy Handaxe Theory' (1999),Hodgson (2009: 195-8) asserts that 'symmetry is not connected with ...

Symmetry as an Inter-Cultural Feature Constituting Beauty: Implicit and Explicit Beauty Evaluation of Visual Symmetry in Japan
Symmetry has been recognized as one of the most important visual features to predict aesthetic preferences and was discussed as a potentially universal feature of beauty judgments....
Soft L-e - L-mu - L-tau flavour symmetry breaking and sterile neutrino keV Dark Matter
Soft L-e - L-mu - L-tau flavour symmetry breaking and sterile neutrino keV Dark Matter
We discuss how a L-e - L-mu - L-tau flavour symmetry that is softly broken leads to keV sterile neutrinos, which are a prime candidate for Warm Dark Matter. This is to our knowledg...

IEEE Transaction on Pattern Analysis and Machine Intelligence
We suggest a set of complex differential operators that can be used to produce and filter dense orientation (tensor) fields for feature extraction, matching, and pattern recognitio...
