Intent Arabic text categorisation based on different machine learning and term frequency
IET Networks, EarlyView., 2022 Abstract The complexity of Internet network configurations has made managing networks a complicated undertaking. Intent‐Based Networking (IBN) is a potential solution to this issue. In contrast to conventional networks, where a concrete description of the settings typically conveys a network administrator's goal kept on each device, an administrator's ...

Scale anomalies, states, and rates in conformal field theory
Journal of High Energy Physics, 2017 This paper presents two methods to compute scale anomaly coefficients in conformal field theories (CFTs), such as the c anomaly in four dimensions, in terms of the CFT data.

Space-Time Defects and Group Momentum Space
Advances in High Energy Physics, 2017 We study massive and massless conical defects in Minkowski and de Sitter spaces in various space-time dimensions. The energy momentum of a defect, considered as an (extended) relativistic object, is completely characterized by the holonomy of the ...

Journal of High Energy Physics, 2017 Supergravity with eight supercharges in a four-dimensional Euclidean space is constructed at the full non-linear level by performing an off-shell time-like reduction of five-dimensional supergravity.

Conserved higher-spin charges in AdS4
Physics Letters B, 2016 Gauge invariant conserved conformal currents built from massless fields of all spins in 4d Minkowski space–time and AdS4 are described in the unfolded dynamics approach. The current cohomology associated with non-zero conserved charges is found.

Renormalizing Open Quantum Field Theories
Universe, 2022 The functional renormalization group flow of a scalar field theory with quartic couplings and a sharp spatial momentum cutoff is presented in four-dimensional Minkowski space-time for the bare action by retaining the entanglement of the IR and the UV ...

On timelike hypersurfaces of the Minkowski 4-space with 1-proper second mean curvature vector [PDF]
Journal of Mahani Mathematical Research, 2023 The mean curvature vector field of a submanifold in the Euclidean $n$-space is said to be $proper$ if it is an eigenvector of the Laplace operator $\Delta$.

The Feynman chessboard model in 3 + 1 dimensions
Frontiers in Physics, 2023 The chessboard model was Feynman’s adaptation of his path integral method to a two-dimensional relativistic domain. It is shown that chessboard paths encode information about the contiguous pairs of paths in a spacetime plane, as required by discrete ...
