Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

Advanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

Advanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Evaluation on the equivalence between the backward/forward iterative sweep and the triangular-based power flow methods in electrical distribution networks

Revista UIS Ingenierías
This paper demonstrates that graph-based power flow methods for strictly radial distribution networks (one based on the upper-triangular matrix and the other on the incidence matrix or classical backward/forward power flow method) are equivalent ...

A Fast Algorithm to Calculate Power Sum of Natural Numbers [PDF]

arXiv, 2018
Permutations can be represented as linear combinations of natural numbers with different powers. In this paper, its coefficient matrix and inverse matrix is derived, and the results show the coefficient matrix is a lower triangular matrix while the inverse matrix is upper triangular.

Thirty-six full matrix forms of the Pascal triangle: Derivation and symmetry relations

Scientific African, 2021
For all 2≤n∈N, the four vertices (00),(n0),(2nn),(nn) of the Pascal Triangle expanded from level 0 to level 2n define the greatest embedded rhomboid sub-block denoted n−GRSB in this paper.

Fixed fields of triangular matrix groups

Journal of Algebra, 2006
AbstractLet K be any field and G be a finite subgroup of GLn(K). Then G acts on the rational function field K(x1,x2,…,xn) by K-automorphisms defined by σ⋅xj=∑1⩽i⩽naijxi if σ=(aij)∈G. Let K(x1,…,xn)G={f∈K(x1,…,xn):σ⋅f=ffor anyσ∈G} be the fixed field. Miyata shows that K(x1,…,xn)G is rational (i.e.

A study on Matrix Domain of Riesz-Euler Totient Matrix in the Space of $p$-Absolutely Summable Sequences

Communications in Advanced Mathematical Sciences, 2021
In this study, a special lower triangular matrix derived by combining Riesz matrix and Euler totient matrix is used to construct new Banach spaces. $\alpha-$,$\beta-$,$\gamma-$duals of the resulting spaces are obtained and some matrix operators ...
