Highly‐Uniform Passive Crossbar Arrays of Resistive Switching Random Access Memory (RRAM) for In‐Memory Computing Applications

Advanced Electronic Materials, EarlyView.
Passive resistive memory arrays promise efficient in‐memory computing but suffer from sneak paths and programming variability. Here, highly uniform 32 × 32 passive RRAM crossbars are programmed with multilevel precision below 3% error and 99.5% yield.

Lanczos meets orthogonal polynomials

Journal of High Energy Physics
We establish a direct correspondence between the Lanczos approach and the orthogonal polynomials approach in random matrix theory. In the large-N and continuum limits, the average Lanczos coefficients and the recursion coefficients become equivalent ...

Dual Szegö pairs of sequences of rational matrix-valued functions

International Journal of Mathematics and Mathematical Sciences, 2006
We study certain sequences of rational matrix-valued functions with poles outside the unit circle. These sequences are recursively constructed based on a sequence of complex numbers with norm less than one and a sequence of strictly contractive matrices.

Analysis of the numerical scheme of the one-dimensional fractional Rayleigh–Stokes model arising in a heated generalized problem

AIP Advances, 2023
In this paper, we present a well-organized method to estimate the one-dimensional fractional Rayleigh–Stokes model using the construction of orthogonal Gegenbauer polynomials (GBPs) and Lagrange square interpolation to estimate the time derivative ...

Protecting Medical Images Using a Zero-Watermarking Approach Based on Fractional Racah Moments

IEEE Access
This article introduces a new family of orthogonal moments, the fractional Racah moments (FrROMs), developed to meet the demands of copyright protection for medical images, a field requiring robust and secure methods that preserve the integrity of the ...

Orthogonal Matrix Polynomials: Zeros and Blumenthal's Theorem

Journal of Approximation Theory, 1996
In this paper the authors investigate orthogonal matrix polynomials \(P_n\) from their matrix three-term recurrence relation \[ tP_n(t)= D_{n+1} P_{n+1} (t)+E_n P_n(t)+ D^*_n P_{n-1}(t), \] where \(D_n\) and \(E_n\) are \(N\times N\) matrices. First, some results regarding the zeros of such matrix polynomials are given, then a quadrature formula is ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

Advanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...
