The Electronic Journal of Linear Algebra, 2017 A graph G is said to be nonsingular (resp., singular) if its adjacency matrix A(G) is nonsingular (resp., singular). The inverse of a nonsingular graph G is the unique weighted graph whose adjacency matrix is similar to the inverse of the adjacency matrix A(G) via a diagonal matrix of ±1s.

The Upper Bound of the Edge Mostar Index with Respect to Bicyclic Graphs
Mathematics, 2023 Let G be a connected graph; the edge Mostar index Moe(G) of G is defined as Moe(G)=∑e=uv∈E(G)|mu(e)−mv(e)|, where mu(e) and mv(e) denote the number of edges in G that are closer to vertex u than to vertex v and the number of edges that are closer to ...

Journal of Field Robotics, EarlyView.ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.

The signature of line graphs and power trees
, 2013 Let $G$ be a graph and let $A(G)$ be the adjacency matrix of $G$. The signature $s(G)$ of $G$ is the difference between the positive inertia index and the negative inertia index of $A(G)$. Ma et al. [Positive and negative inertia index of a graph, Linear

VIEW, EarlyView.The limitations of conventional techniques hinder the identification of natural compounds with anticancer potential in terms of speed, throughput, sensitivity, and capability of continuous monitoring of relevant biological effects. Novel label‐free optical biosensors represent new opportunities in the discovery of drug candidates, eliminating these ...

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting
Wildlife Biology, EarlyView.Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...

The Minimal Total Irregularity of Graphs [PDF]
, 2014 In \cite{2012a}, Abdo and Dimitov defined the total irregularity of a graph $G=(V,E)$ as \hskip3.3cm $\rm irr_{t}$$(G) = \frac{1}{2}\sum_{u,v\in V}|d_{G}(u)-d_{G}(v)|, $ \noindent where $d_{G}(u)$ denotes the vertex degree of a vertex $u\in V$.
