Wiener index of an ideal-based zero-divisor graph of commutative ring with unity

open access: yesAKCE International Journal of Graphs and Combinatorics
The Wiener index of a connected graph G is [Formula: see text]. In this paper, we obtain the Wiener index of H-generalized join of graphs [Formula: see text]. As a consequence, we obtain some earlier known results in [Alaeiyan et al. in Aust. J.

The Wiener Index - Development and Applications

open access: yesCroatica chemica acta, 1995
The definitions and methods of computing the Wiener index are reviewed. It is pointed out that the Wiener index is a useful topological index in the structure-property relationship because it is a measure of the compactness of a molecule in terms of its structural chracteristics, such as branching and cyclicity.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

A Novel Splice Variant in ERGIC1 Causes Arthrogryposis Multiplex Congenita—Characterization Using Urine‐Derived Cells

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis multiplex congenita (AMC) is defined as the presence of joint contractures affecting at least two body regions at birth. Three different ERGIC1 variants have been reported in individuals with AMC. Here, we report on a 16‐year‐old male with a homozygous ERGIC1 c.250+1G>A variant that was classified as a variant of uncertain ...

Extremal estimates of the Wiener index for weakly connected directed graphs

open access: yesМоделирование и анализ информационных систем
The article considers the Wiener index for weakly connected directed graphs. For such graphs, the distance $d(u,v)$ between vertices $u$ and $v$ is not always defined, which requires a correction for the Wiener index to be meaningful.

Artificial Intelligence and Access to Justice at the ‘Shop Front’: The Potential and Limitations of Meeting Legal Need Through Technology

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT In Australia, governments fund Community Legal Centres (CLCs) as part of the legal assistance sector (LAS) to meet the ‘legal needs’ of people experiencing disadvantage who cannot afford private legal services. Persistent unmet demand for CLCs is well‐documented. As artificial intelligence (AI) is increasingly used in private legal practice to

Mechanical Thrombectomy Versus Medical Management for Large Ischemic Core Stroke Identified before Inter‐Hospital Transfer: A Post Hoc Analysis of the LASTE Trial

open access: yesAnnals of Neurology, EarlyView.
Objective This study assessed the efficacy of thrombectomy in acute ischemic stroke because of large‐vessel occlusion (AIS‐LVO) initially admitted to primary stroke centers (PSC) and subsequently transferred to a comprehensive stroke center (CSC), with a large ischemic core identified before transfer.

Maximizing the Wiener Index

open access: yes, 2010
In 1947 and 1948, Harry Wiener published five papers which introduced a pair of graph theoretical invariants, one of which he called the path number, but is now known instead as the Wiener index.

Crossing the Threshold: Using Photostationary States to Control Supramolecular Polymerisation

open access: yesAngewandte Chemie International Edition, EarlyView.
Intermediate photostationary states regulate the concentration of a polymerisation‐active monomer. Once the nucleation threshold is crossed, small wavelength‐dependent changes in isomer composition are amplified into a non‐linear supramolecular assembly response.
