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

Dominating the Direct Product of Two Graphs through Total Roman Strategies

Mathematics, 2020
Given a graph G without isolated vertices, a total Roman dominating function for G is a function f:V(G)→{0,1,2} such that every vertex u with f(u)=0 is adjacent to a vertex v with f(v)=2, and the set of vertices with positive labels induces a graph of ...

The Domus Nozze D'Argento in Pompeii: Structural Diagnosis Using Geophysical Methods

Archaeological Prospection, EarlyView.
ABSTRACT Monitoring of ancient buildings is an issue of great interest in view of a proper restoration. This paper describes the noninvasive monitoring of the Domus Nozze D'Argento in Pompeii. The Roman house, as occurred for many other buildings in Pompei, was buried in the ash from the 79 ad eruption of Mount Vesuvius.

SARchaeological Prospection: Synthetic Aperture Radar for the Reconstruction and Mapping of Temperate Floodplain Environments

Archaeological Prospection, EarlyView.
ABSTRACT Temperate river floodplains present a significant challenge for archaeologists, as cultural and palaeoenvironmental remains are often difficult to locate but can be exceptionally well preserved, especially where groundwater levels are high. In these alluvial environments, the deposition of thick, fine‐grained sediments has potential to deeply ...

Roman Domination Cover Rubbling [PDF]

, 2019
In this thesis, we introduce Roman domination cover rubbling as an extension of domination cover rubbling. We define a parameter on a graph $G$ called the \textit{Roman domination cover rubbling number}, denoted $\rho_{R}(G)$, as the smallest number of ...

Clonal sharing of CD8+ T‐cells links skin and joint inflammation in psoriatic arthritis

Arthritis &Rheumatology, Accepted Article.
Objective Psoriatic arthritis (PsA) is an HLA class I‐associated inflammatory arthritis that develops in up to 30% of people with psoriasis. We tested the hypothesis that skin and joint inflammation in PsA is linked in terms of CD8+ T‐cell phenotype and clonality.

The history of anatomical engagement

Anatomical Sciences Education, EarlyView.
Abstract The public's fascination with anatomy has evolved over time and progressed from avoidance of the tainted yet saintly corpse, to their fascination with cabinets of curiosities. The current narrative review explores public engagement (PE), from its potential origins as cave paintings, to the rise of the disciplinarity of anatomy.
