Some Progress on the Double Roman Domination in Graphs

Discussiones Mathematicae Graph Theory, 2019
For a graph G = (V,E), a double Roman dominating function (or just DRDF) is a function f : V → {0, 1, 2, 3} having the property that if f(v) = 0 for a vertex v, then v has at least two neighbors assigned 2 under f or one neighbor assigned 3 under f, and ...

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

Advanced 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.

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

Advanced 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

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

Advanced 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

Climate Change Agricultural Comparative Advantage and the US Trade Balance

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

The cart tracks at San Pawl tat-Targa, Naxxar [PDF]

, 1994
A notable concentration of cart tracks occurs at T'Alla u Ommu also known as Naxxar Gap at San Pawl tat-Targa, limits of Naxxar. By focusing on the ancient tracks in one specific area, this paper attempts to illustrate which characteristics can be ...

Advanced Experiment Design Strategies for Drug Development

Advanced Intelligent Discovery, EarlyView.
Wang et al. analyze 592 drug development studies published between 2020 and 2024 that applied design of experiments methodologies. The review surveys both classical and emerging approaches—including Bayesian optimization and active learning—and identifies a critical gap between advanced experimental strategies and their practical adoption in ...

Portraits, Power, and Patronage in the Late Roman Republic [PDF]

, 2000
Recent work in ancient art history has sought to move beyond formalist interpretations of works of art to a concern to understand ancient images in terms of a broader cultural, political, and historical context.

New Insights Into Changes in the DNA Methylation Pattern of the SHOX Gene in Patients With Léri‐Weill Dyschondrosteosis

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT SHOX gene haploinsufficiency is associated with Léri‐Weill dyschondrosteosis (LWD) or idiopathic short stature (ISS) and could be caused by the structural and point mutations in the coding region and by the deletions in SHOX gene regulatory sequences. The role of the duplications in regulatory sequences is ambivalent.
