Diazabicyclononanes of formula I and their synthesis ##STR00001## are disclosed. The compounds are useful as scaffolds for constructing combinatorial libraries.

A fitness function circuit for computing a fitness value for a trial solution to a combinatorial problem accelerates the execution speed of a genetic algorithm machine by evaluating trial solutions at the rate of one evaluated solution per clock cycle. The circuit uses repeated tables of data which describe costs associated with each portion of each trial solution to find the total cost associated with each solution. By increasing memory used and repeating the data tables rather than accessing o...

Combinatorial libraries comprise first oligonucleotide analogs and second oligonucleotide analogs which are coupled together to form antisense molecules capable of binding target polynucleotides and activating an RNase, and ribozymes capable of cleaving polynucleotides.

Methods and apparatus for controlling an automated material handling procedure. The method includes receiving a recipe file comprising component information and mapping information; interacting with a user to create a procedure for executing a set of material handling steps; and causing a automated material-handling apparatus to carry out the set of material-handling steps by executing the procedure. The mapping information relates a source component and a destination component. The mapping info...

A random combinatorial selection method is disclosed for the construction of oligonucleotide aptamers in which nuclease resistance is conferred by the inclusion of modified nucleotides. The modified nucleotides are incorporated during PCR amplification to form achiral modified oligonucleotides. Thio-substituted aptamers are provided that bind tightly to the nuclear factor for human IL6 (NF-IL6).
