Signed total double Roman dominating functions in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
A signed total double Roman dominating function (STDRDF) on an isolated-free graph [Formula: see text] is a function [Formula: see text] such that (i) every vertex v with [Formula: see text] has at least two neighbors assigned 2 under f or one neighbor w

The Double Roman Domatic Number of a Digraph

open access: yesDiscussiones Mathematicae Graph Theory, 2020
A double Roman dominating function on a digraph D with vertex set V (D) is defined in [G. Hao, X. Chen and L. Volkmann, Double Roman domination in digraphs, Bull. Malays. Math. Sci. Soc. (2017).] as a function f : V (D) → {0, 1, 2, 3} having the property

Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

open access: yesAdvanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

A Radical Revolution in Thought: Frederick Douglass on the Slave’s Perspective on Republican Freedom [PDF]

open access: yes, 2020
While the image of the slave as the antithesis of the freeman is central to republican freedom, it is striking to note that slaves themselves have not contributed to how this condition is understood.

Surface‐Associated Proteins on Extracellular Vesicles Remodel the Tumor Microenvironment by Potentiating TGF‐β Signaling in a Contact‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Extracellular vesicles (EVs) released from TGF‐β‐activated CAFs are enriched with ECM proteins such as TSG6 and THBS1, which facilitate their binding to recipient cell membranes. This EV–cell interaction promotes the clustering of CD44 and TGF‐β receptors on the target cell surface, thereby potentiating TGF‐β signaling activity. This study highlights a

Masculine crusaders, effeminate Greeks, and the female historian: relations of power in Sir Walter Scott's Count Robert of Paris [PDF]

open access: yes, 2017
Gender employed as a methodological lens in the analysis of historical fiction can help to reveal implicit or explicit evaluative statements. It is deployed here to examine hierarchies in the military, political and cultural context of the encounter ...

The ‘Pierre Duhem Thesis.’ A Reappraisal of Duhem’s Discovery of the Physics of the Middle Ages [PDF]

open access: yes, 2015
Pierre Duhem is the discoverer of the physics of the Middle Ages. The discovery that there existed a physics of the Middle Ages was a surprise primarily for Duhem himself.

Increased Blood Flow and Tendon Swelling Precedes Vascular Expansion and Tissue Matrix Changes In Early Human Tendinopathy: A Potential Window for Superior Treatment Response

open access: yesAdvanced Science, EarlyView.
Human participants with early‐ or chronic‐stage tendinopathy and healthy controls are investigated using ultrasound Doppler, 3T and 7T MRI, and tendon biopsies. Tendon swelling and hyperperfusion are evident early, while vascular growth and extracellular matrix changes are most pronounced in chronic tendinopathy. Early intervention may provide superior

Further Results on Generous Roman Domination [PDF]

open access: yesMathematics Interdisciplinary Research
‎Let G=(V(G),E(G)) be a graph and h be a function defined from V(G) to‎ {0,1,2,3}. A vertex x with h(x)=0 is said to be‎ undefended with respect to $h$ if it has no neighbor assigned‎ 2 or 3 under h‎.
