UNIVERSAL GRAPHS AND UNIVERSAL PERMUTATIONS [PDF]

open access: yesDiscrete Mathematics, Algorithms and Applications, 2013
Let X be a family of graphs and Xn the set of n-vertex graphs in X. A graph U(n) containing all graphs from Xn as induced subgraphs is called n-universal for X. Moreover, we say that U(n) is a propern-universal graph for X if it belongs to X. In the present paper, we construct a proper n-universal graph for the class of split permutation graphs.

Universality of group embeddability [PDF]

open access: yes, 2017
Working in the framework of Borel reducibility, we study various notions of embeddability between groups. We prove that the embeddability between countable groups, the topological embeddability between (discrete) Polish groups, and the isometric ...

Learning automaton‐based self‐protection algorithm for wireless sensor networks

open access: yesIET Networks, 2018
Wireless sensor networks (WSNs) have been widely used for many applications such as surveillance and security applications. Every simple sensor in a WSN plays a critical role and it has to be protected from any attack and failure.

Some Simplicial Complexes of Universal Osborn Loops

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2014
A loop is shown to be a universal Osborn loop if and only if it has a particular simplicial complex. A loop is shown to be a universal Osborn loop and obeys two new identities if and only if it has another particular simplicial complex.

Universality of clonal dynamics poses fundamental limits to identify stem cell self-renewal strategies

open access: yeseLife, 2020
How adult stem cells maintain self-renewing tissues is commonly assessed by analysing clonal data from in vivo cell lineage-tracing assays. To identify strategies of stem cell self-renewal requires that different models of stem cell fate choice predict ...

Intrinsically Universal Cellular Automata

open access: yes, 2009
This talk advocates intrinsic universality as a notion to identify simple cellular automata with complex computational behavior. After an historical introduction and proper definitions of intrinsic universality, which is discussed with respect to Turing ...
