Vacuum and Spacetime Signature in the Theory of Superalgebraic Spinors

open access: yesUniverse, 2019
A new formalism involving spinors in theories of spacetime and vacuum is presented. It is based on a superalgebraic formulation of the theory of algebraic spinors.

spo(2|2)-Equivariant Quantizations on the Supercircle S^{1|2}

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We consider the space of differential operators $mathcal{D}_{lambdamu}$ acting between$lambda$- and $mu$-densities defined on $S^{1|2}$ endowed with its standard contact structure.This contact structure allows one to define a filtration on $mathcal{D}_ ...

Models of Quadratic Algebras Generated by Superintegrable Systems in 2D

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
In this paper, we consider operator realizations of quadratic algebras generated by second-order superintegrable systems in 2D. At least one such realization is given for each set of Stäckel equivalent systems for both degenerate and nondegenerate ...

Unsupervised Classification of Hydrophone Signals With an Improved Mel-Frequency Cepstral Coefficient Based on Measured Data Analysis

open access: yesIEEE Access, 2019
Recently, passive detection technology has developed the ability to detect surface ships based on the noise emissions recorded by hydrophones, making it possible in some cases to classify surface ships.

Multi-dimensional Morse Index Theorems and a symplectic view of elliptic boundary value problems [PDF]

open access: yes, 2011
Morse Index Theorems for elliptic boundary value problems in multi-dimensions are proved under various boundary conditions. The theorems work for star-shaped domains and are based on a new idea of measuring the "oscillation" of the trace of the set of ...

Nonperturbative quantization ‘a la Heisenberg for non-Abelian gauge theories: two-equation approximation. Applications: a flux tube solution and a scalar model of glueball

open access: yesEPJ Web of Conferences, 2017
The nonperturbative quantization technique à la Heisenberg is applied for the SU(3) gauge theory. The operator Yang-Mills equation and corresponding infinite set of equations for all Green’s functions are considered. Gauge degrees of freedom are splitted

Constrained BRST-BFV Lagrangian formulations for higher spin fields in Minkowski spaces

open access: yesJournal of High Energy Physics, 2018
BRST-BFV method to construct constrained Lagrangian formulations for (ir)reducible half-integer higher-spin Poincare group representations in Minkowski space is suggested.

SNEG – Mathematica package for symbolic calculations with second-quantization-operator expressions

open access: yes, 2019
This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract In many-particle problems involving interacting fermions or bosons, the most natural language for expressing the Hamiltonian, the ...

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.
