Sterol and Ceramide Glucosides: Cloning of Enzymes contributing to their Biosynthesis in Plants and Fungi Ernst Heinz Martina Leipelt, Philipp Ternes, Dirk Warnecke, Petra Sperling and in collaboration with Ulrich Zähringer, Forschungsinstitut Borstel, and Stephan Franke, Institut für Organische Chemie, Universität Hamburg Institut für Allgemeine Botanik Universität Hamburg Ohnhorststr. 18 2260...

A protocol for private proximity testing allows two mobile users communicating through an untrusted third party to test whether they are in close physical proximity without revealing any additional information about their locations. At NDSS 2011, Narayanan and others introduced the use of unpredictable sets of “location tags” to secure these schemes against attacks based on guessing another use...

Among other things, we prove that multiquadric surface interpolation is always solvable, thereby settling a conjecture of R. Franke.

We investigate the boundedness of positive solutions of the reciprocal max-type difference equation xn = max { An−1 xn−1 , An−1 xn−2 , . . . , An−1 xn−t } , n = 1, 2, . . . , where, for each value of i, the sequence {An}n=0 of positive numbers is periodic with period pi. We give both sufficient conditions on the pi’s for the boundedness of all solutions and sufficient conditions for all solutio...

The 11th Transgenic Technology meeting was held in Guangzhou, China on 25th–27th February 2013. Over 300 scientists and students from round the world gathered to hear the latest developments in the technologies underpinning the creation of transgenic and knockout animals and their application to biological sciences in areas such as the modeling human diseases and biotechnology. As well as infor...

We discuss the monoidal structure on Franke’s algebraic model for the K(p) -local stable homotopy category at odd primes and show that its Picard group is isomorphic to the integers. MSC: 55P42; 55P60; 55U35
