On the complexity of edge-colored subgraph partitioning problems in network optimization [PDF]

Discrete Mathematics & Theoretical Computer Science, 2016
Network models allow one to deal with massive data sets using some standard concepts from graph theory. Understanding and investigating the structural properties of a certain data set is a crucial task in many practical applications of network ...

Experimental monochromatic light-emitting diode fixture impacts Pekin duck stress and eye development

Poultry Science, 2021
: Poultry color perception of artificial light-emitting diode (LED) lighting mediates bird physiology and behavior; however, very limited research has focused on how changes in LED light color affect these same parameters in Pekin ducks.

A Property on Monochromatic Copies of Graphs Containing a Triangle [PDF]

SIAM Journal on Discrete Mathematics, 2023
A graph $H$ is called common and respectively, strongly common if the number of monochromatic copies of $H$ in a 2-edge-coloring $\phi$ of a large clique is asymptotically minimised by the random coloring with an equal proportion of each color and ...

Study about photoinduction-based technology for trapping small brown planthopper

Frontiers in Plant Science, 2022
To provide a theory to guide the selection of the illumination parameters of light emitting diode (LED)-based light sources used for trapping Laodelphax striatellus, we used LED light sources and devices built in-house to detect L.

Results on monochromatic vertex disconnection of graphs

AIMS Mathematics, 2023
Let $ G $ be a vertex-colored graph. A vertex cut $ S $ of $ G $ is called a monochromatic vertex cut if the vertices of $ S $ are colored with the same color. A graph $ G $ is monochromatically vertex-disconnected if any two nonadjacent vertices of $ G $
