Jet-scheduling control for flat systems

Davide Buccieri

The control of cranes and nonholonomic robots has gained increased interest mainly because of the civilian and military industrial need to achieve fast and accurate transport of goods and equipment. Old and new harbors are now venturing into fully automate ...

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 ...

Total Synthesis of Ecteinascidin 743

Jieping Zhu

A convergent total synthesis of ecteinascidin 743 is realized from five building blocks of almost equal size. It takes 23 steps from L-3-hydroxy-4-methoxy-5-Me phenylalanol (I) with an overall yield of 3%. The most notable features include (a) rapid constr ...

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 ...
