We study the asymptotic probability that a random walk with heavytailed increments crosses a high boundary on a random time interval. We use new techniques to extend results of Asmussen [Ann. Appl. Probab. 8 (1998) 354–374] to completely general stopping times, uniformity of convergence over all stopping times and a wide class of nonlinear boundaries. We also give some examples and counterexamp...

OBJECTIVE The objective of our study was to test the hypothesis that the availability and selective use of STAN in conjunction with cardiotocography for intrapartum monitoring, lowers the incidence of operative deliveries for fetal distress. DESIGN Observational study. SETTING Delivery suite of the National University Hospital, Singapore. METHODS The data regarding intrapartum cesarean se...

Jag, scientifically known as Dalbergja sissoo and Shisham_Persian name_, and local names Sassam, Jag, Jagh and Ciso, is a medium-sized tree that often grows in the highlands and along the mountain rivers. Habitats of this plant species have been reported in India, Bangladesh, Malaysia, Bhutan, Myanmar, Nepal, Pakistan and Afghanistan, and in southeastern Iran in the Makran Heights, Jabal_Barez ...

The anecdote is famous. A mathematician, Stan Ulam, once challenged Paul Samuelson to name one proposition in the social sciences that is both true and non-trivial. His reply was: ‘Ricardo’s theory of comparative advantage’; see Paul Samuelson (1995, p. 22). Truth, however, in Samuelson’s reply refers to the fact that Ricardo’s theory of comparative advantage is mathematically correct, not that...

Inkonsistente und veraltete Datenbestände stellen ein Problem im täglichen privaten und geschäftlichen Alltag dar. Darüber hinaus verlieren wir im Internet mehr und mehr die Datenhoheit über unsere eigenen Daten. Der Ansatz des objektorientierten Webs stellt einen Lösungsvorschlag dar, indem die Idee vom Internet der Dinge um Personen und Unternehmen erweitert wird.

The effect of dissolved water on the diffusivity of Ar in glasses and melts of rhyolitic and albitic compositions was investigated experimentally at pressures up to 1500 MPa and water contents of 0.1^5 wt%. The data for water-poor rhyolitic composition at 500 MPa can be described in the whole temperature range of 480^11023C by a simple Arrhenius relationship DAr = 2.14U1036 m2/s exp(318 883/T)....
