Spanning Trees with Many Leaves in Graphs without Diamonds and Blossoms

, 2007
It is known that graphs on n vertices with minimum degree at least 3 have spanning trees with at least n/4+2 leaves and that this can be improved to (n+4)/3 for cubic graphs without the diamond K_4-e as a subgraph.

Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, EarlyView.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

RAMUS: Printable, Mechanically‐Tunable and Biodegradable Cellulose‐Mediated Composites

Advanced Materials Interfaces, EarlyView.
Ramus, a Latin term meaning “branch,” develops large‐scale, ambient conditions additively manufactured, and biodegradable cellulose‐based biomaterial composites able to mediate their structural capacity from micro to macroscale. Abstract Ramus develops large‐scale, ambient conditions additively manufactured, and biodegradable cellulose‐based ...

Control of Copper Morphology on TaN through Surface Point Defects

Advanced Materials Interfaces, EarlyView.
In this study, DFT and dynamics simulations are used to explore the tailoring of the morphology of Cu metal deposits by surface nitrogen vacancy defects on the TaN diffusion barrier. Vacancy formation can be promoted by hydrogen reduction. High vacancy concentrations limit unwanted 3D growth, suggesting defect engineering as a strategy for targeted ...

Performance of a simple ACO on the minimum label spanning tree problem

Discover Applied Sciences
The minimum label spanning tree problem is an NP-complete combinatorial optimization problem. Experiments have shown that the ant colony optimization is effective for solving this problem.
