Jet-Scheduling Control for SpiderCrane: Experimental Results

Dominique Bonvin, Christophe Salzmann, Philippe Müllhaupt, Davide Buccieri

SpiderCrane is a three-dimensional crane, whose main particularity lies in the absence of large inertial moving parts. This paper presents experimental results obtained with the novel jet-scheduling control methodology that is based on differential flatnes ...

Directed evolution of O6-alkylguanine-DNA alkyltransferase for applications in protein labeling

Kai Johnsson, Christian Heinis, Alexandre Juillerat, Christopher Chidley, Thomas Gronemeyer

The specific reaction of O6-alkylguanine-DNA alkyltransferase (AGT) with O6-benzylguanine (BG) derivatives allows for a specific labeling of AGT fusion proteins with chemically diverse compounds in living cells and in vitro. The efficiency of the labeling ...

Time-lag in Derivative Convergence for Fixed Point Iterations

Daniel Kressner

In an earlier study it was proven and experimentally confirmed on a 2D Euler code that fixed point iterations can be differentiated to yield first and second order derivatives of implicit functions that are defined by state equations. It was also asserted ...

Heterosubstituted or functionalized derivatives of 1- and 2-(trifluoromethyl)naphthalenes emanating from aryne adducts

Frédéric Bailly, Fabrice Cottet

More than two dozen new CF3-substituted naphthalene derivs. were prepd. in an expedient way by employing 3- and 4-(trifluoromethyl)benzyne as the key intermediates. 2- And 4-Chlorobenzotrifluoride were treated with butyllithium and the organometallic speci ...

Semi-Orthogonal Wavelets That Behave like Fractional Differentiators

Michaël Unser, Dimitri Nestor Alice Van De Ville, Thierry Blu

The approximate behavior of wavelets as differential operators is often considered as one of their most fundamental properties. In this paper, we investigate how we can further improve on the wavelet's behavior as differentiator. In particular, we propose ...

Scope and limitations of the double [4+3]-cycloadditions of 2-oxyallyl cations to 2,2 '-methylenedifuran and derivatives

Pierre Vogel, Marc-Etienne Schwenter, Kai Torsten Meilert

The reactivity of various 2-oxyallyl cations toward 2,2'-methylenedifuran (1b), 2,2'-(hydroxymethyl)difuran (1c), 2,2'-(trimethylsilylmethylene)difuran (1d), and di(2-furyl)methanone (1e) has been explored. Difuryl derivatives 1c, 1d, and le refused to und ...

Asymmetric synthesis of 1-aminopentadecane-3,5,7,9,11,13,15-heptols and of 1,15-diaminopentadecane-3,5,7,9,11,13-hexols and derivatives

Pierre Vogel, Sandrine Gerber

Starting from 2,2'-methylenedifuran, enantiomerically enriched (98%) (3R,5S,7R,9S,11R,13R)- and (3R,5S,7S,9R,11R,13R)-15-amino-5,7,9,11-tetrahydroxy-3,13-bis(4-methoxyb enzoyloxy)pentadec-1-yl) pivalate were prepared as well as (3R,5R,7R,9R,11S,13S)-1,15-d ...

Derivatives of (2R,3R,4S)-2-Aminomethylpyrrolidine-3,4-diol are Selective alpha-Mannosidase Inhibitors

Pierre Vogel, Sandrine Gerber, Inmaculada Robina, Eliazar Rodriguez Garcia, Raynald Demange

A collection of (2R,3R,4S)-3,4-dihydroxypyrrolidin-2-yl derivatives have been tested for their inhibitory activities toward 25 glycosidases. Competitive (K-i=7.4 VM) and selective inhibition of alpha -mannosidase from jack bean has been found for (2R,3R,4S ...

Using Multiple Time Scales in the Framework of Multi-Stream Speech Recognition

Hervé Bourlard, Astrid Hagen

In this paper, we present a new approach to incorporating multiple time scale information as independent streams in multi-stream processing. To illustrate the procedure, we take two different sets of multiple time scale features. In the first system, these ...
