xperimental evaluation of various task-space control algorithms shows that significant deviations from desired trajectories may occur, especially at higher speeds, or in the vicinity of singularities. The experiments on a modular reconfigurable robotic setup confirmed this conclusion: the lateral deviations may range up to several centimeters from the closest point on the desired trajectory. Th...

CombinaTexas 2018 February 10 – 11 , 2018

In this talk we give combinatorial proofs of q-Stirling identities using restricted growth words. This includes a poset theoretic proof of Carlitz’s identity, a new proof of the q-Frobenius identity of Garsia and Remmel and of Ehrenborg’s Hankel q-Stirling determinantal identity. We also develop a two parameter generalization to unify identities of Mercier and include a symmetric function versi...

'Epidemic neuromyasthenia' 1955-1978.

A record of fifty-three patients admitted to the Infectious Diseases Department of the Royal Free Hospital between April 1955 and September 1957 suffering from 'epidemic neuromyasthenia' establishes the fact that the condition was endemic in the general population before, during and after the outbreak among the staff of the hospital. A further outbreak occurred in North Finchley between 1964 an...

Stefan Jentsch (1955–2016)

Stefan Jentsch, whose unusual creativity and trailblazing work changed forever the fields of ubiquitin biology, DNA repair, splicing, and autophagy, sadly passed away in Munich on October 29 after a short and severe illness. Stefan was born in Berlin on May 29, 1955. Following his school and university years, Stefan embarked on his graduate thesis in his still-divided hometown and joined Thomas...
