Dynamics of Randomly Constructed Computational Systems [PDF]
, 2010 We studied Petri nets with five places constructed in a pseudo-random way: their underlying net is composed of join and fork. We report initial results linking the dynamical properties of these systems to the topology of their underlying net.

Norbornene Homopolymerization Limits Cell Spreading in Thiol–Ene Photoclick Hydrogels
Advanced 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 ...

Aggregation Scheme with Secure Hierarchical Clustering for Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2012 In a large-scale wireless sensor network, a topology is needed to gather state-based data from sensor network and efficiently aggregate the data given the requirements of balanced load, minimal energy consumption, and prolonged network lifetime.

Localized Fault Tolerant and Connectivity Restoration Algorithms in Mobile Wireless Ad Hoc Network
IEEE Access, 2018 Due to the dynamic characteristics of mobile wireless ad hoc networks, a node may join or leave/fail at anytime, and links are usually intermittently unavailable. The destruction of the network connectivity would dramatically degrade the performance.

A topological transformation in evolutionary tree search methods based on maximum likelihood combining p-ECR and neighbor joining [PDF]
BMC Bioinformatics, 2008 Abstract Background Inference of evolutionary trees using the maximum likelihood principle is NP-hard. Therefore, all practical methods rely on heuristics. The topological transformations often used in heuristics are Nearest Neighbor Interchange (NNI), Subtree Prune and Regraft (SPR) and Tree Bisection and ...

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials
Advanced Materials, EarlyView.Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.
