Continuous and Discrete ZND Models with Aid of Eleven Instants for Complex QR Decomposition of Time-Varying Matrices

open access: yesMathematics, 2023
The problem of QR decomposition is considered one of the fundamental problems commonly encountered in both scientific research and engineering applications.

Spontaneous dimensional reduction in quantum gravity [PDF]

open access: yes, 2016
Hints from a number of different approaches to quantum gravity point to a phenomenon of “spontaneous dimensional reduction” to two spacetime dimensions near the Planck scale.

Gauged supergravity from dimensional reduction [PDF]

open access: yes, 1997
We perform a generalised Scherk-Schwarz reduction of the effective action of the heterotic string on T6 to obtain a massive N = 4 supergravity theory in four dimensions.

Restoration of dimensional reduction in the random-field Ising model at five dimensions. [PDF]

open access: yesPhysical Review E, 2016
The random-field Ising model is one of the few disordered systems where the perturbative renormalization group can be carried out to all orders of perturbation theory.

Supersymmetry Breaking by Dimensional Reduction over Coset Spaces [PDF]

open access: yes, 2000
We study the dimensional reduction of a ten-dimensional supersymmetric E_8 gauge theory over six-dimensional coset spaces. We find that the coset space dimensional reduction over a symmetric coset space leaves the four dimensional gauge theory without ...

Emergence of time persistence in a data-driven neural network model

open access: yeseLife, 2023
Establishing accurate as well as interpretable models of network activity is an open challenge in systems neuroscience. Here, we infer an energy-based model of the anterior rhombencephalic turning region (ARTR), a circuit that controls zebrafish swimming

Dimensional reduction and topological invariants of symmetry-protected topological phases [PDF]

open access: yes, 2017
We review the dimensional reduction procedure in the group cohomology classification of bosonic SPT phases with finite abelian unitary symmetry group. We then extend this to include general reductions of arbitrary dimensions and also extend the procedure

Compressing Fisher Vector for Robust Face Recognition

open access: yesIEEE Access, 2017
One major topic for robust face recognition could be the efficient encoding of facial descriptors. Among various encoders, Fisher vector (FV) is one of the probabilistic methods that yield promising results.

Classical aspects of lightlike dimensional reduction [PDF]

open access: yes, 2006
Some aspects of lightlike dimensional reduction in flat spacetime are studied with emphasis to classical applications. Among them the Galilean transformation of shadows induced by inertial frame changes is studied in detail by proving that, (i) the ...
