The metropolis can be analysed as an infrastructure in perpetual motion, composed of built elements – the system “hardware” – and social networks – the system “software”. The emergence of an overall city-scale infrastructure composed not of a single unit b ...
Given a possibly reducible and non-reduced spectral cover pi: X -> C over a smooth projective complex curve C we determine the group of connected components of the Prym variety Prym(X/C). As an immediate application we show that the finite group of n-torsi ...
A novel technology is presented for arrays of vertical flaps as optically modulating elements which are actuated electrostatically to horizontal position at low voltages of 30-50V. One application is a reflective display exhibiting a contrast ratio of 1:95 ...

We prove that the norm of the Euler class E for flat vector bundles is 2−n (in even dimension n, since it vanishes in odd dimension). This shows that the Sullivan-Smillie bound considered by Gromov and Ivanov-Turaev is sharp. We construc ...
Environmental labelling is an accountability mechanism for firms to satisfy growing demands to prove that value chains are sustainably managed. Although the large variety of ecolabels available today can be interpreted as a sign of their success, it is ove ...
Indoor scenes are characterized by a high intra-class variability, mainly due to the intrinsic variety of the objects in them, and to the drastic image variations due to (even small) view-point changes. One of the main trends in the literature has been to ...
Embedded memories consume an increasingly dominant part of the overall area and power of a large variety of systems-on-chip [ITRS’09]: 1) biomedical implants and wireless sensor networks require robust memories operating in the sub-VT domain; 2) many handh ...
In the late 19th century, F.-A. Forel led investigations of the Rhone River delta area of Lake Geneva that resulted in the discovery of a textbook example of a river-fed delta system containing impressive subaquatic channels. Well ahead of the marine count ...
It is shown that 2-dimensional subdivisions can be made regular by moving their vertices within parallel 1-dimensional spaces. As a consequence, any 2-dimensional subdivision is projected from the boundary complex of a 4-polytope. ...
T cells are the key mediators in cell-mediated immunity. Their development and maturation involve a complex variety of interactions with nonlymphoid cell products and receptors. Highly specialized to defend against bacterial and viral infections, T cells a ...
