Cacti with Extremal PI Index [PDF]
Transactions on Combinatorics, 2016 The vertex PI index PI(G)=∑ xy∈E(G) [n xy (x)+n xy (y)] PI(G)=∑xy∈E(G)[nxy(x)+nxy(y)] is a distance-based molecular structure descriptor, where n xy (x) nxy(x) denotes the number of vertices which are closer to the vertex x x than to the vertex y y

On vertex PI index of certain triangular tessellation networks
Main Group Metal Chemistry, 2021 The Wiener index, due to its many applications is considered to be one of very important distance-based index. But the Padmaker-Ivan (PI) index is kind of the only distance related index linked to parallelism of edges.

Computing PI and Szeged indices of multiple phenylenes and cyclic hexagonal-square chain consisting of mutually isomorphic hexagonal chains [PDF]
Journal of the Serbian Chemical Society, 2007 PI and Szeged indices are two of the most important topological indices defined in chemistry. In this study, the PI and Szeged indices of linear [n]-phenylenes and a cyclic hexagonal-square chain consisting of n mutually isomorphic hexagonal chains were ...

Phase‐index correlation delay shift keying modulation
IET Communications, 2022 High‐data‐rate phase‐orthogonality correlation‐delay‐shift‐keying (HPO‐CDSK) transmits 2‐bits orthogonal signal in parallel and achieve higher spectral efficiency in the category of non‐coherent detection chaotic systems. However, the spectral efficiency

Perfusion index and pleth variability index in the first hour of life according to mode of delivery
The Turkish Journal of Pediatrics, 2018 Perfusion index (PI) is a relative assessment of the pulse strength at the monitoring site. The plethysmographic variability index (PVI, pleth variability index) is a noninvasive and continuous measure of the dynamic change in PI that occurs during ...
