We formulate C. Freiling’s axioms of symmetry for general second-order structures with respect to a certain ideal of small sets contained in them and find several equivalent formulations of the principles. Then we focus on particular models, namely saturated and recursively saturated ones, and show that they are symmetric with respect to appropriate classes of small sets when their second-order...
We demonstrate narrow transmission resonances at near-infrared wavelengths utilizing coupled asymmetric split-ring resonators (SRRs). By breaking the symmetry of the coupled SRR system, one can excite dark (subradiant) resonant modes that are not readily accessible to symmetric SRR structures. We also show that the quality factor of metamaterial resonant elements can be controlled by tailoring ...
Background: Changes in load during asymmetric holding may be associated with particularly high risk of loss of balance and spinal injury. Therefore, in order to assess occupational lesions and to make preventive rehabilitation programs in such conditions like holding dynamic loads in asymmetric postures could be important. Methods: In a cross-sectional study, COP amplitude and velocit...
Competitive Spatial Pricing for Urban Parking Systems: Network Structures and Asymmetric Information
Inspired by new technologies to monitor parking occupancy and process market signals, we aim expand the application of demand-responsive pricing in industry. Based on a graphical Hotelling model wherein each garage has information for its incoming demand, consider general competitive spatial systems under an asymmetric structure. We focus impact urban network structure incentive sharing. Our an...
