Analog Tensor Processing With Carbon Nanotube In‐Memory Matrix Multiplications for Edge Computer Vision Acceleration

Advanced Materials, EarlyView.
This work prototypes a carbon nanotube‐based analog tensor core that performs in‐memory, parallel visual processing. Integrating non‐volatile memories and compact circuits, the core enables high‐speed analog matrix multiplications and can demonstrate accurate three dimensional (3D) spatial transformation and edge detection. With lightweight design, the

Degree-Based Topological Indices of the Jacobson Graph of Zm×Zn×Zr

Journal of Mathematics
Let R be a commutative ring with unity. The Jacobson graph IR of R is an undirected simple graph whose vertex set is R\JR, where JR is a Jacobson ideal of R, and for any distinct vertices x,y∈R\JR are adjacent if and only if 1−xy is not a unit of R.

Topological aspects of some dendrimer structures

Nanotechnology Reviews, 2018
A numerical number associated to the molecular graph G that describes its molecular topology is called topological index. In the study of QSAR and QSPR, topological indices such as atom-bond connectivity index, Randić connectivity index, geometric index,

Eccentricity-Based Topological Indices of a Cyclic Octahedron Structure

Mathematics, 2018
In this article, we study the chemical graph of a cyclic octahedron structure of dimension n and compute the eccentric connectivity polynomial, the eccentric connectivity index, the total eccentricity, the average eccentricity, the first Zagreb index ...

An Approach to the Geometric-Arithmetic Index for Graphs under Transformations’ Fact over Pendent Paths

Complexity, 2021
Graph theory is a dynamic tool for designing and modeling of an interconnection system by a graph. The vertices of such graph are processor nodes and edges are the connections between these processors nodes. The topology of a system decides its best use.

Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Computing GA_{5} index of armchair polyhex nanotube

Le Matematiche, 2014
The fifth geometric-arithmetic index of a graph $G$ is defined to be GA_5(G). This index was introduced by  A. Graovac et al.  in 2011. In this paper, we give explicit formulas for the fifth geometric-arithmetic index of a family of Hexagonal Nanotubes ...

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Directional Latent Hybridization: Beyond Random Noise in Physics‐Informed Generative Inverse Design of Nonlinear Metamaterials

Advanced Materials Technologies, EarlyView.
A physics‐informed generative framework introduces Directional Latent Hybridization (DLH) for the deterministic inverse design of nonlinear metamaterials. By hybridizing dominant traits from parent geometries in the latent space, DLH overcomes the instabilities of stochastic models to ensure high structural precision at high densities.
