Stochastic spanning tree problem

open access: yesDiscrete Applied Mathematics, 1981
AbstractThe minimal spanning tree problem has been well studied and until now many efficient algorithms such as [5,6] have been proposed. This paper generalizes it toward a stochastic version, i.e., considers a stochastic spanning tree problem in which edge costs are not constant but random variables and its objective is to find an optimal spanning ...

Norbornene Homopolymerization Limits Cell Spreading in Thiol–Ene Photoclick Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
Thiol–norbornene click reactions are often used in the development of cell‐permissive 3D hydrogels. However, ene–ene crosslinks in other thiol–ene systems are known to limit permissivity. This study demonstrates the negative effects of norbornene homopolymerization on 3D cell spreading and circumvents the issue by modulating polymer degree of ...

Spanning Trees Minimizing Branching Costs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
The Minimum Branch Vertices Spanning Tree problem aims to find a spanning tree $T$ in a given graph $G$ with the fewest branch vertices, defined as vertices with a degree three or more in $T$.

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases

open access: yesAdvanced Materials, EarlyView.
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

open access: yesAdvanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.
