SHOP: a method for structure-based fragment and scaffold hopping.
A new method for fragment and scaffold replacement is presented that generates new families of compounds with biological activity, using GRID molecular interaction fields (MIFs) and the crystal structure of the targets. In contrast to virtual screening strategies, this methodology aims only to replace a fragment of the original molecule, maintaining the other structural elements that are known ...
متن کاملSHOP: scaffold HOPping by GRID-based similarity searches.
A new GRID-based method for scaffold hopping (SHOP) is presented. In a fully automatic manner, scaffolds were identified in a database based on three types of 3D-descriptors. SHOP's ability to recover scaffolds was assessed and validated by searching a database spiked with fragments of known ligands of three different protein targets relevant for drug discovery using a rational approach based o...
متن کاملJob-shop scheduling in a body shop
We study a generalized job-shop problem called the body shop scheduling problem (BSSP). This problem arises from the industrial application of welding in a car body production line, where possible collisions between industrial robots have to be taken into account. BSSP corresponds to a job-shop problem where the operations of a job have to follow alternating routes on the machines, certain oper...
متن کاملControl of Hopping Height for a One-Legged Hopping Machine
The control of the hopping height in a one-legged machine is studied. The general aim is to decrease sensitivity of the hopping height to drifts in the machine’s parameters. The proposed approach combines a near-inverse controller which uses height feedback, with a recursive least-squares parameter estimator which continually tunes the controller. The paper presents the mechanical design of the...
متن کاملTime hopping and frequency hopping in ultrawideband systems
This paper analyzes frequency-hopping (FH) and time-hopping (TH) as multiple access format for ultrawideband communications. We apply the concept of fourthegy, recently introduced by Subramanian and Hajek, to both TH and FH.We find that the design rules are different for FCCcompliant systems(where the power spectral density is limited)than for conventional systems(where the energy per bit is li...
