The Wiener Index of Random Trees [PDF]
Combinatorics, Probability and Computing, 2002 The Wiener index is analysed for random recursive trees and random binary search trees in uniform probabilistic models. We obtain expectations, asymptotics for the variances, and limit laws for this parameter. The limit distributions are characterized as the projections of bivariate measures that satisfy certain fixed point equations.

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development
Advanced Science, EarlyView.This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.

Wiener index and Harary index on Hamilton-connected graphs with large minimum degree
Discrete Applied Mathematics, 2018 In this paper, we give some sufficient conditions for connected graphs with given minimum degree to be Hamilton-connected and traceable from every vertex in terms of Wiener index and Harary index. We also prove sufficient conditions on Harary index of G ¯

Intrinsic Mechanical Parameters and their Characterization in Solid‐State Lithium Batteries
Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.This review focuses on the intrinsic mechanical parameters and their associated characterization in solid‐state batteries. The physical significance of mechanics parameters is introduced with exhaustive classifications by elastic, plastic deformations and fracture in bulk, adhesion, friction at interfaces, and mechanical fatigue in cells ...

Advanced Energy Materials, EarlyView.Operando magnetic spectroscopy provides insight into how intrinsic magnetic order modulates the oxygen evolution reaction on La0.67Sr${\rm La}_{0.67}{\rm Sr}$0.33MnO$_{0.33}{\rm MnO}$3$_3$ thin films. Temperature‐dependent operando FMR and ambient‐pressure XMCD suggest a correlation between activity and the emergence of ferromagnetic regions near and ...

Farmers’ Protests in Germany: Media Coverage and Types of Bias
Agribusiness, EarlyView.ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.

The Steiner Wiener Index of A Graph
Discussiones Mathematicae Graph Theory, 2016 The Wiener index W(G) of a connected graph G, introduced by Wiener in 1947, is defined as W(G) = ∑u,v∈V(G) d(u, v) where dG(u, v) is the distance between vertices u and v of G. The Steiner distance in a graph, introduced by Chartrand et al. in 1989, is a

Advanced Intelligent Systems, EarlyView.The newly developed AI‐automated Fast Fourier Transform denoising algorithm surpasses conventional real‐space methods by revealing even light atoms otherwise hidden in noisy backgrounds. Atomic resolution electron microscopy has become an essential tool for many scientific fields, when direct visualization of atomic arrangements and defects is needed ...

Steiner Wiener index of graph products [PDF]
Transactions on Combinatorics, 2016 The Wiener index W(G) of a connected graph G is defined as W(G)=∑u,v∈V(G)dG(u,v) where dG(u,v) is the distance between the vertices u and v of G.
