K-Poincare-Hopf algebra and Hopf algebroid structure of phase space from twist
, 2013 We unify k-Poincare algebra and k-Minkowski spacetime by embeding them into quantum phase space. The quantum phase space has Hopf algebroid structure to which we apply the twist in order to get k- deformed Hopf algebroid structure and k-deformed phase ...

A note on the algebraic growth rate of Poincar\'e series for Kleinian groups
, 2009 In this note we employ infinite ergodic theory to derive estimates for the algebraic growth rate of the Poincar\'e series for a Kleinian group at its critical exponent of convergence.Comment: 8 ...

Experimental Physiology, EarlyView.Abstract Sleep apnoea (SA) is ∼2 times more prevalent in men than women. However, this changes at menopause as the occurrence of SA increases and matches that of men. Menopause is a natural process, but it remains unclear why SA emerges only in a subpopulation of ageing women.

On smooth manifolds with homotopy type of a homology sphere
, 2018 In this paper we study $\mathcal M(X)$, the set of diffeomorphism classes of smooth manifolds with the simple homotopy type of $X$, via a map $\Psi$ from $\mathcal M(X)$ into the quotient of $K(X)=[X,BSO]$ by the action of the group of homotopy classes ...

Kappa-Minkowski differential calculi and star product
, 2011 We present the star-product algebra of the kappa-deformation of Minkowski space and the formulation of Poincare covariant differential calculus. We use these tools to construct a twisted K-cycle over the algebra and a twisted cyclic cocycle.Comment ...

The Journal of Physiology, EarlyView.Abstract figure legend Time‐resolved estimation of cardiac rhythmicity parameters. A pipeline is shown for the estimation of the fluctuating cardiac parameters, based on the Poincaré plot. The Poincaré plot illustrates the successive changes in interbeat intervals (IBI).

Analysis of Transient Processes in a Radiophysical Flow System
, 2006 Transient processes in a third-order radiophysical flow system are studied and a map of the transient process duration versus initial conditions is constructed and analyzed.
