SYK Model with global symmetries in the double scaling limit

open access: yesJournal of High Energy Physics, 2023
We discuss the double scaling limit of the SYK model with global symmetries. We develop the chord diagram techniques to compute the moments of the Hamiltonian and the two point function in the presence of arbitrary chemical potential.

Improved Local Ternary Patterns for Automatic Target Recognition in Infrared Imagery

open access: yesSensors, 2015
This paper presents an improved local ternary pattern (LTP) for automatic target recognition (ATR) in infrared imagery. Firstly, a robust LTP (RLTP) scheme is proposed to overcome the limitation of the original LTP for achieving the invariance with ...

Spaces of states of the two-dimensional $O(n)$ and Potts models

open access: yesSciPost Physics, 2023
We determine the spaces of states of the two-dimensional $O(n)$ and $Q$-state Potts models with generic parameters $n,Q\in \mathbb{C}$ as representations of their known symmetry algebras.

ORTHOGONAL PARTITIONS OF THE 6times6 LATIN SQUARES [PDF]

open access: yesAnnals of Eugenics, 1946
The articles published by the Annals of Eugenics (1925–1954) have been made available online as an historical archive intended for scholarly use. The work of eugenicists was often pervaded by prejudice against racial, ethnic and disabled groups. The online publication of this material for scholarly research purposes is not an endorsement of those views

Expansion Methods for Solving Linear Integral Equations with Multiple Time Lags Using B-Spline and Orthogonal Functions [PDF]

open access: yesEngineering and Technology Journal, 2011
The main portion of the paper is devoted for constructing approximated solutions of linear integral equations with multiple time lags (IEMTL) using two different types of basis functions B-spline functions and Orthogonal functions containing (Laguerre ...

3d N=2 SO/USp adjoint SQCD: s-confinement and exact identities

open access: yesNuclear Physics B, 2023
We study 3d N=2 SQCD with symplectic and orthogonal gauge groups and adjoint matter. For USp(2n) with two fundamentals and SO(N) with one vector these models have been recently shown to s-confine.

Channel estimation method for FBMC/OQAM system based on pilot

open access: yes上海师范大学学报. 自然科学版, 2016
Compared with orthogonal frequency division multiplexing technology (OFDM),filter bank multicarrier (FBMC) technique has higher spectrum using rate and easier achieved pulse shaping.It was seen as a potential replacement for OFDM as future 5G physical ...

FDD Downlink Channel Estimation Solution With Common Sparsity Learning Algorithm and Zero-Partition Enhanced GAMP Algorithm

open access: yesIEEE Access, 2018
To acquire precise channel state information in the forthcoming 5G frequency division duplexing (FDD) communication system, we study the virtual angular domain channel common sparsity in the massive multiple-input multiple-output orthogonal frequency ...

Classical group matrix models and universal criticality

open access: yesJournal of High Energy Physics, 2022
We study generalizations of the Gross-Witten-Wadia unitary matrix model for the special orthogonal and symplectic groups. We show using a standard Coulomb gas treatment — employing a path integral formalism for the ungapped phase and resolvent techniques
