A new topological aspect of the arbitrary dimensional topological defects

, 1999
We present a new generalized topological current in terms of the order parameter field $\vec \phi$ to describe the arbitrary dimensional topological defects.

M-Polynomials and Topological Indices of Dominating David Derived Networks

Open Chemistry, 2018
There is a strong relationship between the chemical characteristics of chemical compounds and their molecular structures. Topological indices are numerical values associated with the chemical molecular graphs that help to understand the physical features,

A novel representation of RNA secondary structure based on element-contact graphs

BMC Bioinformatics, 2008
Background Depending on their specific structures, noncoding RNAs (ncRNAs) play important roles in many biological processes. Interest in developing new topological indices based on RNA graphs has been revived in recent years, as such indices can be used

Bulk-Edge correspondence for two-dimensional Floquet topological insulators

, 2018
Floquet topological insulators describe independent electrons on a lattice driven out of equilibrium by a time-periodic Hamiltonian, beyond the usual adiabatic approximation.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Determining topological order from a local ground state correlation function

, 2011
Topological insulators are physically distinguishable from normal insulators only near edges and defects, while in the bulk there is no clear signature to their topological order.

Degree-Based Topological Indices

Croatica Chemica Acta, 2013
The degree of a vertex of a molecular graph is the number of first neighbors of this vertex. A large number of molecular-graph-based structure descriptors (topological indices) have been conceived, depending on vertex degrees. We summarize their main properties, and provide a critical comparative study thereof.

Unleashing the Power of Machine Learning in Nanomedicine Formulation Development

Advanced Functional Materials, EarlyView.
A random forest machine learning model is able to make predictions on nanoparticle attributes of different nanomedicines (i.e. lipid nanoparticles, liposomes, or PLGA nanoparticles) based on microfluidic formulation parameters. Machine learning models are based on a database of nanoparticle formulations, and models are able to generate unique solutions

Multiplicative Valency-Based Descriptors for Silicon Carbides Si2C3 − I[p, q], Si2C3 − II[p, q], Si2C3 − III[p, q], and SiC3 − III[p, q] in Drug Applications

Journal of Chemistry, 2020
Topological indices help us to collect information about algebraic graphs and give us a mathematical approach to understand the properties of algebraic structures.
