The aim of this study was to evaluate the sources, transport and distribution of hydrophobic organic contaminants produced in an urban area. Passive sampling devices (PSDs) were employed in the storm-water drainage of the city of Lahti, in an adjacent boreal lake (Vesijärvi) and along its shore. Samples were analysed for 16 polycyclic aromatic hydrocarbons (PAHs) and 28 polychlorinated biphenyl...

Activation of Cdc14 phosphatase, controlled by a signalling cascade known as the mitotic exit network, is the final switch that drives cells from mitosis into the next cell cycle. The recent discovery of a novel network that regulates early Cdc14 activation has revealed the unexpected existence of a two-step control of mitotic exit.

We recently demonstrated a new approach to mul-tiframe structure from motion from point features which, in the appropriate domain, provably reconstructs structure and motion correctly. The algorithm works for general motion and large perspective eeects. In this paper, we describe how to adapt our approach to translational motion lying along a line or in a plane, with arbitrary rotations. An ana...
