https://en.wikipedia.org/wiki/Brian%20Johnson%20%28special%20effects%20artist%29 | Brian Johnson (born 29 June 1939 or 29 June 1940) is a British designer and director of film and television special effects.
Life and career
Born Brian Johncock, he changed his surname to Johnson during the 1960s. Joining the team of special effects artist Les Bowie, Johnson started his career behind the scenes for Bo... |

https://en.wikipedia.org/wiki/Average%20bitrate | In telecommunications, average bitrate (ABR) refers to the average amount of data transferred per unit of time, usually measured per second, commonly for digital music or video. An MP3 file, for example, that has an average bit rate of 128 kbit/s transfers, on average, 128,000 bits every second. It can have higher bitr... |
https://en.wikipedia.org/wiki/Unicore | Unicore is the name of a computer instruction set architecture designed by the Microprocessor Research and Development Center (MPRC) of Peking University in the PRC. The computer built on this architecture is called the Unity-863.
The CPU is integrated into a fully functional SoC to make a PC-like system.

https://en.wikipedia.org/wiki/Explicit%20symmetry%20breaking | In theoretical physics, explicit symmetry breaking is the breaking of a symmetry of a theory by terms in its defining equations of motion (most typically, to the Lagrangian or the Hamiltonian) that do not respect the symmetry. Usually this term is used in situations where these symmetry-breaking terms are small, so tha... |
https://en.wikipedia.org/wiki/Little%20Higgs | In particle physics, little Higgs models are based on the idea that the Higgs boson is a pseudo-Goldstone boson arising from some global symmetry breaking at a TeV energy scale. The goal of little Higgs models is to use the spontaneous breaking of such approximate global symmetries to stabilize the mass of the Higgs bo... |
https://en.wikipedia.org/wiki/Dimensional%20deconstruction | In theoretical physics, dimensional deconstruction is a method to construct 4-dimensional theories that behave as higher-dimensional theories in a certain range of higher energies. The resulting theory is a gauge theory whose gauge group is a direct product of many copies of the same group; each copy may be interpreted... |
https://en.wikipedia.org/wiki/Crossing%20%28physics%29 | In quantum field theory, a branch of theoretical physics, crossing is the property of scattering amplitudes that allows antiparticles to be interpreted as particles going backwards in time.
Crossing states that the same formula that determines the S-matrix elements and scattering amplitudes for particle to scatter wi... |
https://en.wikipedia.org/wiki/Pauli%E2%80%93Villars%20regularization |
In theoretical physics, Pauli–Villars regularization (P–V) is a procedure that isolates divergent terms from finite parts in loop calculations in field theory in order to renormalize the theory. Wolfgang Pauli and Felix Villars published the method in 1949, based on earlier work by Richard Feynman, Ernst Stueckelberg... |
https://en.wikipedia.org/wiki/Dimensional%20regularization |
In theoretical physics, dimensional regularization is a method introduced by Giambiagi and Bollini as well as – independently and more comprehensively – by 't Hooft and Veltman for regularizing integrals in the evaluation of Feynman diagrams; in other words, assigning values to them that are meromorphic functions of ... |
https://en.wikipedia.org/wiki/Microconnect%20distributed%20antenna | Microconnect distributed antennas (MDA) are small-cell local area (100 metre radius) transmitter-receivers usually fitted to lampposts and other street furniture in order to provide Wireless LAN, GSM and GPRS connectivity. They are therefore less obtrusive than the usual masts and antennas used for these purposes and m... |
