The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Powers of Large Matrices on GPU Platforms to Compute the Roman Domination Number of Cylindrical Graphs

IEEE Access, 2021
The Roman domination in a graph G is a variant of the classical domination, defined by means of a so-called Roman domination function f : V (G) - {0, 1, 2} such that if f (v) = 0 then, the vertex v is adjacent to at least one vertex w with f (w) = 2. The

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

Archaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Prevalence of Cam Femoroacetabular Lesions in Medieval (1200‐1600 CE) and Postmedieval (1600‐1850 CE) Dutch Skeletal Collections

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate medieval and postmedieval Dutch skeletal collections for signs of cam impingent. Methods The medieval collections from Alkmaar Paardenmarkt and Klaaskinderkerke and the postmedieval period from Middenbeemster were studied. Standard osteological methods for sex and age estimation were used. From digital photographs of the femora, the

The Distance Roman Domination Numbers of Graphs

Discussiones Mathematicae Graph Theory, 2013
Let k be a positive integer, and let G be a simple graph with vertex set V (G). A k-distance Roman dominating function on G is a labeling f : V (G) → {0, 1, 2} such that for every vertex with label 0, there is a vertex with label 2 at distance at most k ...

Use of antiemetics in early pregnancy 2012–2022: A cross‐sectional study

British Journal of Clinical Pharmacology, EarlyView.
Aim Nausea and vomiting in pregnancy impact quality of life, yet many pregnant women feel dismissed by healthcare professionals, despite the safety of first‐line antiemetic treatments for both mother and fetus. Therefore, this study aims to describe the prevalence of patient‐reported antiemetic use in early pregnancy in Copenhagen, Denmark, the changes

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Roman domination excellent graphs: trees

Communications in Combinatorics and Optimization, 2016
A Roman dominating function (RDF) on a graph $G = (V, E)$ is a labeling $f : V \rightarrow \{0, 1, 2\}$ such that every vertex with label $0$ has a neighbor with label $2$. The weight of $f$ is the value $f(V) = _{v\in V} f(v)$. The Roman domination number, $ _R(G)$, of $G$ is the minimum weight of an RDF on $G$. An RDF of minimum weight is called a

Corruption Control and Corporate Hazardous Waste Emissions: Cross‐Country Evidence and the Moderating Role of Agenda 2030

Business Strategy and the Environment, EarlyView.
ABSTRACT The aim of this study is to examine the impact of corruption control, as a public institutional mechanism, on hazardous waste emissions of private sector entities. We also examine the extent to which Agenda 2030 moderates the relationship. We analyse data from the top 500 global companies.

Weak signed Roman k-domination in digraphs [PDF]

Opuscula Mathematica
Let \(k\geq 1\) be an integer, and let \(D\) be a finite and simple digraph with vertex set \(V(D)\). A weak signed Roman \(k\)-dominating function (WSRkDF) on a digraph \(D\) is a function \(f \colon V(D)\rightarrow \{-1,1,2\}\) satisfying the condition
