Solid–Liquid Triboelectric Nanogenerators as Physicochemical Encoders for Intelligent Liquid Recognition

Interdisciplinary Materials, EarlyView.
Solid–liquid triboelectric nanogenerators are conceptualized as dynamic physicochemical encoders that encode intrinsic liquid properties into distinguishable triboelectric fingerprints. This review provides a unified framework for these platforms, covering sensing mechanisms in droplet impact, continuous flow, and immersion modes.

Commuting graphs of gamma rings

Open Mathematics
Let M be a non-commutative gamma ring and ZΓM ${Z}_{{\Gamma}}\left(M\right)$ denote the center of the gamma ring M. The vertices a and b are consecutive if a ≠ b and aαb = bαa for every α ∈ Γ, with vertices taken from the set M−ZΓM $M-{Z}_{{\Gamma ...

On the Clique Numbers of Non-commuting Graphs of Certain Groups

Algebra Colloquium, 2010
Let G be a non-abelian group. The non-commuting graph [Formula: see text] of G is defined as the graph whose vertex set is the non-central elements of G and two vertices are joint if and only if they do not commute. In a finite simple graph Γ, the maximum size of complete subgraphs of Γ is called the clique number of Γ and denoted by ω(Γ).

Convergence theorem for non-commutative Feynman graphs and renormalization [PDF]

Journal of High Energy Physics, 2001
We present a rigorous proof of the convergence theorem for the Feynman graphs in arbitrary massive Euclidean quantum field theories on non-commutative R^d (NQFT). We give a detailed classification of divergent graphs in some massive NQFT and demonstrate the renormalizability of some of these theories.

Metric Properties of Non-Commuting Graph Associated to Two Groups

International Journal of Foundations of Computer Science, 2022
The non-commuting graph associated to a group has non-central elements of the graph as vertices and two elements [Formula: see text] and [Formula: see text] do not form an edge if and only if [Formula: see text]. In this paper, we consider non-commuting graphs associated to dihedral and semidihedral groups.

Improving Affordability and Accessibility for Socially‐Beneficial Services via Government Incentives

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Many socially‐beneficial services, like dental care, suffer from a dual challenge: Low affordability for citizens and long waiting times due to insufficient provider capacity. We model a government's problem of designing subsidy policies to address this issue.

A novel method to construct NSSD molecular graphs

Open Mathematics, 2019
A graph is said to be NSSD (=non-singular with a singular deck) if it has no eigenvalue equal to zero, whereas all its vertex-deleted subgraphs have eigenvalues equal to zero.

Tourism, Well‐Being, and Sustainability: Trends, Impacts, and Perspectives

Sustainable Development, EarlyView.
ABSTRACT Research on sustainable tourism, tourists, and well‐being has key implications for tourism policies, which must align with the SDGs to enhance the well‐being of visitors and local communities. This paper analyzes the evolution of scientific production through a systematic literature review over the last 25 years.

Environmental Footprint of Diffuse Emissions in European Functional Urban Areas

Sustainable Development, EarlyView.
ABSTRACT This paper quantifies the environmental footprint of diffuse air emissions across 776 European functional urban areas (FUAs) from 2005 to 2022 by coupling Copernicus Atmosphere Monitoring Service (CAMS) gridded inventories with the Environmental Footprint (EF) 3.1 framework.
