PURPOSE We investigated the accuracy of analysis of detrusor contraction during micturition with a simple to use pressure-flow nomogram (linear passive urethral resistance relation). The computer derived maximum detrusor contraction parameter was used as a reference. The correlation with bladder emptying capability was used as a control. MATERIALS AND METHODS Advanced pressure-flow analysis w...

We prove that the family of all invariant sets of iterated systems of contractions R → R is a nowhere dense Fσ type subset in the space of the non-empty compact subsets of R equipped with the Hausdorff metric. An iterated function system (IFS for short) is a finite collection (T1, . . . , Tn) of weak contractions of a metric space X. By a weak contraction we mean a mapping T : X → X such that d...

We give an introduction to a notion of weak dependence which is more general than mixing and allows to treat for example processes driven by discrete innovations as they appear with time series bootstrap. As a typical example, we analyze autoregressive processes and their bootstrap analogues in detail and show how weak dependence can be easily derived from a contraction property of the process....

To determine for the first time, whether "pumping" or "weak contraction," defined as blastocoelic contraction by more than 8 microns in diameter, is associated with poor implantation rates, independent of other morphokinetic features. We analyzed 148,441 images from time-lapse sequences 317 expanded blastocysts, chosen transfer, known data. Using a computer vision algorithm, we were able to mea...

Geodesic contraction in vector-valued differential equations is readily verified by linearized operators which are uniformly negative-definite the Riemannian metric. In infinite-dimensional setting, however, such analysis generally restricted to norm-contracting systems. We develop a generalization of geodesic rates Banach spaces using smoothly-weighted semi-inner product structure on tangent s...

Context. Stars experience rapid contraction or expansion at different phases of their evolution. Modelling the transport angular momentum and chemical elements occurring during these remains an unsolved problem. Aims. We study a stellar radiative zone undergoing radial investigate induced differential rotation meridional circulation. Methods. consider rotating spherical layer crossed by imposed...

Using the weak convergence approach to large deviations, we formulate and prove deviation principle (LDP) for W-random graphs in cut-norm topology. This generalizes LDP Erd?s–Rényi random by Chatterjee Varadhan. Furthermore, translate a class of interacting dynamical systems on such graphs. To this end, demonstrate that solutions models depend continuously underlying with respect apply contract...
