The Exact Parity Model (EPM) sees the ordinary particle sector reflected, darkly, in a mirror sector. It is a phenomenologically acceptable extension of the Standard Model (SM) of particle physics which displays invariance under Improper Lorentz Transformations (Parity and Time-Reversal invariance). Remarkably, the invariance or otherwise of microphysical laws and the physical vacuum under the ...

ion Space The definition of an implementation link is as a representation map from an abstract theory to a concrete theory, wi th an abstraction function for mapping concrete objects to abstract objects. The diagram below shows an implementation link between bags and lists, where the abstract theory of bags and the concrete theories of lists are axiomatized using equational logic. Abstraction M...

We experimentally study quantum Zeno effects in a parity-time (PT) symmetric cold atom gas periodically coupled to reservoir. Based on the state-of-the-art control of inter-site couplings atoms momentum lattice, we implement synthetic two-level system with passive PT symmetry over two lattice sites, where an effective dissipation is introduced through repeated rest lattice. Quantum (anti-Zeno) ...

Quantum-dot Cellular Automata (QCA) is a prominent paradigm that is considered to continue its dominance in thecomputation at deep sub-micron regime in nanotechnology. The QCA realizations of five-input Majority Voter based multilevel parity generator circuits have been introduced in recent years. However, no attention has been paid towards the QCA instantiation of the generic (n-bit) even and ...

We consider the advanced modulation and coding schemes used in CCSDS (Consultative Committee for Space Data Systems) standards for deep space telemetry and telecommand. They are based on a powerful turbo or low-density parity check (LDPC) outer code and binary modulation formats that, for those schemes foreseen to be employed at the lowest baud rates, may contain an unsuppressed carrier to help...
