We thank Dr Reynolds for carefully reading and commenting on our article, and indeed must agree that the maximum score on the Oudega rule is 13 points (as a patient cannot be both male and taking oral contraceptives). We do stress, however, that from a GP’s point of view, the most valuable use of the Oudega rule is to exclude deep venous thrombosis (DVT). For that purpose, a threshold at three ...

We generalize and extend results obtained by Boneh and Venkatesan in 1996 and by González Vasco and Shparlinski in 2000 on the hardness of computing bits of the Diffie-Hellman key, given the public values. Specifically, while these results could only exclude (essentially) error-free predictions, we here exclude any non-negligible advantage, though for larger fractions of the bits. We can also d...

Técnicas de transientes de corrente potenciostáticos foram empregadas no estudo de processos de eletroredução de camadas superficiais formadas no cobalto policristalino em soluções contendo íons carbonato-bicarbonato. As análises dinâmicas do sistema, realizadas através de procedimentos de investigação paramétrica e de rotinas de ajuste não-lineares, demonstraram que os da dos obtidos sob numa ...

Abstract Direct spring operated pressure relief valves are regular elements of high-pressure hydraulic systems; however, valve vibrations may still occur endangering the and protected system. The damping these is a crucial issue, whereas external viscous at cannot be increased boundlessly based on safety aspects. emerge via Hopf bifurcations either super- or subcritical type, nonlinear characte...

We use proper motions and parallaxes from the new reduction of Hipparcos data and Geneva-Copenhagen radial velocities for a complete sample of ∼ 15 000 main-sequence and subgiant stars, and new Padova isochrones to constrain the kinematics and starformation history of the solar neighbourhood. We rederive the solar motion and the structure of the local velocity ellipsoids. When the principal vel...
