Consider a C 1+ diieomorphism f having a uniformly hyperbolic compact invariant set , maximal invariant in some small neighbourhood of itself. The asymp-totic exponential rate of escape from any small enough neighbourhood of is given by the topological pressure of ? log jJ u fj on (Bowen{Ruelle 1975]). It has been conjectured (Eckmann{Ruelle 1985]) that this property, formulated in terms of esc...

The American Hospital Association [6] (AHA), joined by the American Medical Association [7] (AMA), brought the suit against the US Department of Health and Human Services [8] (HHS) and its then-director Otis R. Bowen [9], to have a series of requirements for neonatal care struck down. These requirements?the first set of Baby Doe Rules?were created by the HHS and US President Ronald Reagan's Adm...

We consider the sets of quasi-regular points in the countable symbolic space. We measure the sizes of the sets by Billingsley-Hausdorff dimension defined by Gibbs measures. It is shown that the dimensions of those sets, always bounded from below by the convergence exponent of the Gibbs measure, are given by a variational principle, which generalizes Li and Ma’s result and Bowen’s result.

To the Editor: Seborrheic keratosis is one of the most common benign epidermal tumors in dermatologic clinical practice. Although the association between seborrheic keratosis and other skin tumors was first reported in 1932, its malignant transformation is very rare, with less than 20 published cases. We present the case of a patient with seborrheic keratosis that underwent transformation into ...
