Lower and upper bounds on independent double Roman domination in trees

Electronic Journal of Graph Theory and Applications, 2022
For a graph G = (V, E), a double Roman dominating function (DRDF) f : V → {0, 1, 2, 3} has the property that for every vertex v ∈ V with f(v)=0, either there exists a neighbor u ∈ N(v), with f(u)=3, or at least two neighbors x, y ∈ N(v) having f(x)=f(y ...

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

Quasi total double Roman domination in graphs

AKCE International Journal of Graphs and Combinatorics
A quasi total double Roman dominating function (QTDRD-function) on a graph [Formula: see text] is a function [Formula: see text] having the property that (i) if f(v) = 0, then vertex v must have at least two neighbors assigned 2 under f or one neighbor w

Experimental Demonstration of Temporally Aware Fault‐Tolerant Sensor Fusion Using Memristive Associative Learning

Advanced Electronic Materials, EarlyView.
In dynamic driving scenarios, the proposed approach ensures only temporally aligned sensor inputs to make driving decisions, preventing false activations. By enabling selective hardware‐level learning, it achieves fast, reliable responses under noisy conditions.

The double Roman domination number of generalized Sierpiński graphs [PDF]

Discrete Mathematics, Algorithms and Applications, 2020
In this paper, we study the double Roman domination number of generalized Sierpiński graphs [Formula: see text]. More precisely, we obtain a bound for the double Roman domination number of [Formula: see text]. We also find the exact value of [Formula: see text].

On the D-differential of a graph

AKCE International Journal of Graphs and Combinatorics, 2022
Let [Formula: see text] be a graph of order n(G). For a subset S of V(G), the boundary of S is defined as [Formula: see text] where N(S) is the open neighborhood of S.

Defining Frailty in Chinese‐Language Biomedical Literature (2014–2024): A Decade of Conceptual Evolution

AGING MEDICINE, EarlyView.
Frailty definitions in Chinese‐language biomedical literature increasingly align with international frameworks, while retaining conceptual diversity, underscoring the need for multidimensional, cross‐cultural research and integration with traditional Chinese medicine for culturally sensitive clinical practice.

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 ...

On The Co-Roman Domination in Graphs

Discussiones Mathematicae Graph Theory, 2019
Let G = (V, E) be a graph and let f : V (G) → {0, 1, 2} be a function. A vertex v is said to be protected with respect to f, if f(v) > 0 or f(v) = 0 and v is adjacent to a vertex of positive weight. The function f is a co-Roman dominating function if (i)

Hydration Behavior of Tricalcium Silicate in Seawater Relevant Salt Systems: A Hybrid Study with the Aid of Machine Learning

Advanced Intelligent Discovery, EarlyView.
The hydration behavior of C3S in seawater‐relevant solutions is studied based on experiments, boundary nucleation and growth (BNG) modeling, and machine learning. The main ions included in seawater modify hydration mechanisms, with MgCl2 showing the strongest acceleration effect at the same concentration.
