We thus observe the phenomenon of symmetry breaking in gauge gravitation theory which exhibits the physical nature of gravity as a Higgs field (Sardanashvily, 1991; Sardanashvily and Zakharov, 1992).

Although this is a natural process from the string theory point of view, this phenomenon is not visible in the gauge theory living on the 4-brane worldvolume.

However, it is quite natural to see that in the underlying theory as a complete theory for at least the UV limit or short distance limit physics the space-time variables are again some kind of ’LE phenomenological’ quantities, there must be deeper structures behind the space-time phenomenon.
On the underlying theory approach for quantum theories
Under certain conditions phase diagrams present negative thermal derivatives of some transition pressures, a phenomenon observed in nature in water, for instance.

The study of the behaviour of fires in wildland regions has traditionally been driven by the needs of those practitioners involved in wildland resource management– foresters for the most part–for whom understanding this natural phenomenon was critical to the success of their work.

Real world physical phenomenons are intrinsically passive, hence the loss of passivity also means the loss of the physical nature of the simulation .

Such a phenomenon of pessimistic or optimistic attitude fundamentally altering the nature of discrimination seems not to have been described before.

From our perspective, the study of the thermalization of a particle in simultaneous interaction with two heat baths should shed light on this phenomenon already at the classical level, especially focusing on the energy distribution which, in the presence of finite resources, is not necessarily of Boltzmann nature.
Thermalization in open classical systems with finite heat baths
Steganalysis of LACK is harder to perform than for most other steganographic methods that were described in Section 1. Packet loss in IP networks is a “natural phenomenon”, so intentional losses introduced by LACK are not easy to detect, if kept on a reasonable level.

The rest of this work is devoted to the rigorous analysis of this two-time-scale phenomenon in the special case when the stochastic process alluded above is a fragmentation-coagulation process induced by a natural modification of Pitman’s coalescing random forests .

The Fermi liquid nature of the ground state [119] and the various theoretical treatments, including Wilson’s numerical renormalisation group (NRG) [120], make the Kondo problem one of the best understood many-body phenomenon in condensed matter physics, as well as a paradigm for correlated electron physics [121].
