Shadowing, ergodic shadowing and uniform spaces

Seyyed Ahmadi
2017 Filomat  
We introduce and study the topological concepts of ergodic shadowing, chain transitivity and topological ergodicity for dynamical systems on non-compact non-metrizable spaces.  ...  We prove that a dynamical system with topological ergodic shadowing property is topologically chain transitive, and that topological chain transitivity together with topological shadowing property implies  ...  Acknowledgment I would like to thank the anonymous referee for the excellent job.  ...

Topological entropy, pseudo-orbits and uniform spaces

Kesong Yan, Fanping Zeng
2016 Topology and its Applications  
We introduce the notions of pseudo-orbit entropy, periodic pseudoorbit entropy and pseudo-orbit point entropy for continuous maps on compact uniform spaces, and study their relationships with the topological  ...  But a pseudo-orbit can be used to approximate the real orbit, and so there has been a lot of applications in many fields, for instance, Grebogi, Hammel and Yorke [10, 11] have investigated the role of  ...  I thank the anonymous referee for his/her helpful comments and suggestions that improved the manuscript. Part of this work was carried out when Yan visited NCTS.  ...

On Preventing Location Attacks for Urban Vehicular Networks

Meng Zhou, Xin Li, Lejian Liao
2016 Mobile Information Systems  
In this paper, we proposed a sophisticated prediction model to predict driver's next location by using a k-order Markov chain-based third-rank tensor representing the partially observed transfer information  ...  We argue that such data contains rich informative cues on drivers' private behaviors and preferences, which will lead to the location privacy attacks.  ...  Acknowledgments The authors would also like to thank Dr. Xiaofeng  ...

A Conley-type decomposition of the strong chain recurrent set

2017 Ergodic Theory and Dynamical Systems  
For a continuous flow on a compact metric space, the aim of this paper is to prove a Conley-type decomposition of the strong chain recurrent set.  ...  We then show that strongly stable sets play the role of attractors in the decomposition of the strong chain recurrent set; indeed, we prove that the strong chain recurrent set coincides with the intersection  ...  The authors are sincerely in debt with the anonymous referee who proposed to use the name "strongly stable set" and explained the relation between strongly stable and stable sets.  ...

Kinetics of chromosome condensation in the presence of topoisomerases: a phantom chain model

J.L. Sikorav, G. Jannink
1994 Biophysical Journal  
Using a known model describing the collapse of homopolymers, we propose that the compaction process necessitates a change in the topological state (i.e., a self-knotting) of the chromosomal chain.  ...  A phantom chain model for the condensation process, in which each potential entanglement point is dealt with by a topoisomerase 11 molecule, is proposed.  ...  We were greatly helped by the remarks of an anonymous referee.  ...

Blockchain and Data Protection: A Compatible Couple?

Ceyhun Necati Pehlivan, Inés Isidro Read
2020 Global Privacy Law Review  
As various European institutions and data protection authorities point out, this type of technologies may, by its very nature, be unable to comply with the General Data Protection Regulation (GDPR).  ...  Thus, the impact of blockchain on the privacy and personal data of data subjects generally requires analysis on a case-by-case basis.  ...  As mentioned, the hash function is the common technique on which the blockchain is based in order to compact and pseudonymize the data in the network.  ...
