The Signed Total Roman k-Domatic Number Of A Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2017
Let k ≥ 1 be an integer. A signed total Roman k-dominating function on a graph G is a function f : V (G) → {−1, 1, 2} such that Ʃu2N(v) f(u) ≥ k for every v ∈ V (G), where N(v) is the neighborhood of v, and every vertex u ∈ V (G) for which f(u) = −1 is ...

Total roman domination number of graphs

open access: yes, 2022
In this paper a characterization of minimal total roman dominating functions has been proved. It has also been proved that if v is a pendant vertex and its neighbor u is not a pendant vertex then f(v) = 0 or 1 for any minimal total roman dominating function f. The operation of vertex removal has been considered.

The Application of Carbon Dots in Crops for Sustainable Agriculture

open access: yesChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Ring‐opening metathesis polymerization‐Derived Organoborane Polymers as Strong Lewis Acids and Luminescent Materials

open access: yesChemistryEurope, EarlyView.
Ring‐opening metathesis polymerization offers access to borane polymers with tunable Lewis acidity, environmental stability, and luminescence. The Lewis acid strength approaches that of B(C6F5)3 when R = Cl and Ar = C6F5, high stability is ensured with chlorophenyl or naphthyl pendent groups (Ar = ClPh, Np), and strong emission is achieved with a ...

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
