New results on the Estrada index of graphs
FilomatLet G be a graph of order n and let ?1, ?2,..., ?n be the eigenvalues of G. The Estrada index of G, denoted by EE(G), is the sum of the terms e?i. In this paper, new lower and upper bounds for the Estrada index are established.

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Archaeological Prospection, EarlyView.ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

A New Like Quantity Based on "Estrada Index"
Journal of Inequalities and Applications, 2010 We first define a new Laplacian spectrum based on Estrada index, namely, Laplacian Estrada-like invariant, LEEL, and two new Estrada index-like quantities, denoted by S and , respectively, that are generalized versions of the Estrada index. After that,

Navigating the Double Edge of Product‐Service Systems: User Behavior, Adoption, and Rebound Effects
Business Strategy and the Environment, EarlyView.ABSTRACT Product‐service systems (PSS) have been considered a promising approach to operationalizing the circular economy. Although many studies have outlined the potential sustainability gains of PSS solutions, it is still unclear what factors drive PSS adoption and how behavioral changes result in rebound effects, undermining their potential ...
