The Anatomical Record, EarlyView.Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

A Different Short Proof of Brooks’ Theorem
Discussiones Mathematicae Graph Theory, 2014 Lovász gave a short proof of Brooks’ theorem by coloring greedily in a good order. We give a different short proof by reducing to the cubic case.

Ideal based graph structures for commutative rings
Cubo, 2022 We introduce a graph structure $\gamrr$ for commutative rings with unity. We study some of the properties of the graph $\gamrr$. Also we study some parameters of $\gamrr$ and find rings for which $\gamrr$ is split.

The Anatomical Record, EarlyView.Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Animal empathy reconsidered: a multidimensional profile account
Biological Reviews, EarlyView.ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

, 2015 The clique graph, K(G), of a graph G is the intersection graph of the maximal cliques of G. For a natural number n, a graph G is n-convergent if K-n(G) is isomorphic to ICI (the one-vertex graph).

Linear Clique-Width for Hereditary Classes of Cographs [PDF]
, 2016 The class of cographs is known to have unbounded linear clique-width. We prove that a hereditary class of cographs has bounded linear clique-width if and only if it does not contain all quasi-threshold graphs or their complements. The proof borrows ideas

Business Strategy and the Environment, EarlyView.ABSTRACT Despite growing interest in corporate relocation decisions and sustainability, the existing literature is limited in its consumer‐centric approach. Integrating social exchange theory and construal level theory, this research investigates how consumers perceive sustainability‐driven nearshoring motives (i.e., socio‐economic vs.

On maximizing clique, clique-Helly and hereditary clique-Helly induced subgraphs [PDF]
, 2010 Clique-Helly and hereditary clique-Helly graphs are polynomial-time recognizable. Recently, we presented a proof that the clique graph recognition problem is NP-complete [L. Alcón, L. Faria, C.M.H. de Figueiredo, M. Gutierrez, Clique graph recognition is
