Zero forcing sets and minimum rank of graphs

Linear Algebra and its Applications, 2008
The minimum rank of a simple graph G is defined to be the smallest possible rank over all symmetric realmatrices whose ijth entry (for i /= j ) is nonzero whenever {i, j } is an edge in G and is zero otherwise. Thispaper introduces a new graph parameter, Z(G), that is the minimum size of a zero forcing set of verticesand uses it to bound the minimum ...

Influence of Particle Shape and Size in Copper‐Based Low‐Temperature Metallization Paste for Solar Cells

Advanced Engineering Materials, EarlyView.
Particle morphology controls the balance between printability and electrical connectivity in low‐temperature AgCu/Ag metallization pastes. Flake‐shaped AgCu particles form extended low‐resistance contacts, whereas spherical particles favor processability at high metal loading. Fine Ag particles further tune void filling and conductive‐network formation

Observationally constrained global warming hysteresis under CO2 removal

Communications Earth & Environment
Stabilizing global warming under ongoing anthropogenic warming will likely require atmospheric carbon dioxide removal. However, the extent to which carbon dioxide removal can reverse past warming remains uncertain due to divergent responses across a ...

Investigation of Resonance Characteristics of More Than 10 000 Metal‐Coated Silicon MEMS Cantilevers Using Machine Learning

Advanced Engineering Materials, EarlyView.
More than 10 000 metal‐coated silicon MEMS cantilevers are fabricated and characterized to build a large‐scale experimental dataset spanning multiple vibrational modes. Machine learning algorithms are benchmarked to predict resonance frequency and quality factor, with ensemble based models achieving accuracy approaching experimental uncertainty.

Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

Advanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

K-Hop Zero Forcing and Its K-Propagation Time.

In this paper, we introduce a new variant of zero forcing, called K-hop zero forcing. We study this concept and its behavior in some classes of graphs such as complete and the join of a trivial graph and a path graph with order n.
