Topological entropy is not lower semi-continuous: small perturbation of the dynamical system can lead to a collapse entropy. In this note we show that for some special classes systems (geodesic flows, Reeb positive contactomorphisms) topological at least stable in sense there exists nontrivial continuous bound, given certain homological invariant grows exponentially.

Descriptions are given of the Langevin and diffusion equation passively marked fluid particles in turbulent flow with spatially varying anisotropic statistical properties. The descriptions consist first two terms an expansion powers C0−1, where C0 is autonomous Lagrangian-based Kolmogorov constant: C0≈7. Solutions involve application methods stochastic analysis while complying basic laws physic...

I would like to comment on the paper by Beiraghdar et al. (1). C2 is regarded as a better indicator of cyclosporine A (CsA) exposure compared to C0 (2), this is also the case in pediatric patients (3). However, in clinical settings, C0 monitoring seems to be more reliable. It is connected to the fact that, CsA blood concentration is quite stable for between 10 and 12 hours after administration,...

We investigated the transport and retention kinetics of silica encapsulated – core double stranded DNA particles (SiDNASi) through 15 cm saturated quartz sand columns as a function wide range colloid injection concentrations (C0 = 8.7 ×102 - 6.6 ×108 ml?1). The breakthrough curves (BTCs) exhibited an overall 2-log increase maximum relative effluent concentration with increasing C0. Inverse curv...
