Motivated by the Kyle-Back model of \insider trading", we consider certain classes of linear transformations of two independent Brownian motions and study their canonical decomposition, i.e., their Doob-Meyer decomposition as semimartingales in their own ltration. In particular we characterize those transformations which generate again a Brownian motion. 1 Support of the EU through the TMR cont...

It is a great pleasure to welcome you to Uppsala and the 16’th Affi nity Conference. Uppsala hosts northern Europe ́s oldest university, the workplace for luminaries such as Linnaeus, Celsius, and Arrhenius, and this has been the site of path-breaking developments in protein separation from the early 1920’s to the present. Well known are Profs. The Svedberg (the ultracentifuge), Arne Tiselius (e...

Let T be an ergodic automorphism of the d-dimensional torus T, and f be a continuous function from T to R. On the probability space T equipped with the Lebesgue-Haar measure, we prove the weak convergence of the sequential empirical process of the sequence (f ◦T )i≥1 under some condition on the modulus of continuity of f . The proofs are based on new limit theorems and new inequalities for non-...

Snow scavenging of sub-micrometre aerosol particles is poorly known, even though it is an important aerosol removal mechanism in the polar and mountainous regions as well as in the upper troposphere and in mid-latitudes in winter. In our study, snow scavenging coeffi cients were calculated using four years of particle number concentration spectra measurements together with meteorological measur...

T. Schlichter and L. Montes (eds.), Forests in Development: A Vital Balance, DOI 10.1007/978-94-007-2576-8_5, © Springer Science+Business Media B.V. 2012 Abstract South American tree plantations expand at a rate of 5,000 km 2 /year favored by increasingly globalized markets and local economic conditions. The main hydrological impacts of these plantations involve shifts in (a) the partition of p...

Background There is increasing evidence that the immunogenicity of aortic valve allografts (AVA) is associated with valvular degeneration. Chemically induced cell extraction is expected to reduce an immune response. However, whether this will translate into reduced structural damage is unclear. The present study focussed at characterizing the immune response to cellular and acellular AVA and co...

s S73 marker of disease activity, was abnormally elevated (>39 ms) in approximately 1/3 of all muscles. No changes were observed from baseline on MRI parameters. Mean increase from baseline in the 6MWT was 37.3 meters (p = 0.02). Eleven patients improved; 4 patients worsened. Mean improvement from baseline in percent predicted FVC was 1.8% (p = 0.67). Seven patients improved; 8 patients worsene...

the article by Schwenger and colleagues [1] on sustained low-effi ciency dialysis (SLED) versus continuous venovenous hemofi ltration (CVVH) in surgical patients with acute kidney injury. Th e authors have to be congratulated for their eff orts to shed some light on the clinical usefulness of the SLED technology as an alternative to conventional renal replacement therapy (RRT) modalities.

1 Under the microscope 1.1 Osculating spaces of homogeneous varieties Let G be a simply connected complex semisimple Lie group, g its Lie algebra, and g its tensor algebra. The universal envelopping algebra of U(g) is the quotient of this tensor algebra by the ideal generated by the elements xy ? yx ? x; y], x; y 2 g. This quotient algebra inherits a ltration from the natural grading of the ten...
