By bringing together the right materials duking it out, a Cornell-led collaboration has for the first time used voltage to turn on and off a material’s crystal symmetry, thereby controlling its electr...
THE PARALLEL IMPLEMENTATION OF ALGORITHMS FOR FINDING THE REFLECTION SYMMETRY OF THE BINARY IMAGES
Reflection Symmetry of Images Binary Images High-Performance Computing Parallel Performance Evaluation
2017/6/19
In this paper, we investigate the exact method of searching an axis of binary image symmetry, based on brute-force search among all potential symmetry axes. As a measure of symmetry, we use the set-th...

symmetry underlies search for new materials
2015/12/7
A new symmetry operation developed by Penn State researchers has the potential to speed up the search for new advanced materials that range from tougher steels to new types of electronic, magnetic, an...
Instability of one-step replica-symmetry-broken phase in satisfiability problems
Solutions random stability high energy density
2015/8/21
We reconsider the one-step replica-symmetry-breaking (1RSB) solutions of two random combina- torial problems: k-XORSAT and k-SAT. We present a general method for establishing the stability of these so...
Clusters of solutions and replica symmetry breaking in random k-satisfiability
Random formula decomposition quantity index
2015/8/21
We study the set of solutions of random k-satisfiability formulae through the cavity method. It is known that, for an interval of the clause-to-variables ratio, this decomposes into an exponenti...
Forcing neurocontrollers to exploit sensory symmetry through hard-wired modularity in the game of Cellz
Structure coding scheme modular evolutionary system coding
2015/7/31
Several attempts have been made in the past to construct encoding schemes that allow modularity to emerge in evolving systems, but success is limited. We believe that in order to create successful and...
Gauge Symmetry Breaking in Gauge Theories---In Search of Clarification
Gauge Symmetry Gauge Theories Clarification
2011/8/11
Abstract: The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle. Local gauge symmetry itself cannot break spontaneously in quantized gauge th...
The Isotopic Foldy-Wouthuysen Representation and Chiral Symmetry
Isotopic Foldy-Wouthuysen Chiral Symmetry General Physics
2011/8/2
Abstract: The paper introduces the isotopic Foldy-Wouthuysen representation. This representation was used to derive equations for massive interacting fermion fields. When the interaction Hamiltonian c...
Symmetry-induced Dispersion and performance penalty in Coupled Resonator Optical Waveguides
Micro-optical devices Coupled resonators
2015/6/8
We show that for fundamental reasons, microdisk based CROWs possess two non-degenerate transmission modes, making their long-planned use in optical communications highly challenging. Interference betw...

Suppressing the effect of disorders using time-reversal symmetry breaking in magneto-optical photonic crystals: An illustration with a four-port circulator
Magneto-optics Photonic crystals Optical resonances Channel add/drop fi lters Optical circulators Nonreciprocity
2015/8/11
In integrated optical systems, nonreciprocal elements are indispensable devices that eliminate multi-path reflection between components. To miniaturizing these devices down to a single-wavelengt...
