The Inventory/Shipping package of the NCI Drug Information System (DIS) is designed to support all inventory and shipping operations associated with the testing by the NCI of large numbers of chemicals for anticancer activity. Two major databases, an Inventory database and a Shipping History database, contain all of the data associated with these… (More)
The Pre-Registry Module of the Drug Information System (DIS) is a staging area through which all new compounds are passed prior to acquisition and testing. Several methods are available for the entry of structures into the Pre-Registry; all involve built-in data validation. Newly entered structures are examined by computer programs for structural novelty… (More)
The Chemistry Module of the Drug Information System (DIS) handles a database of 400,000 structures. New or modified records are created in this database on a daily basis and are merged into the file promptly. The Chemistry database is searchable in a wide variety of ways and provides novel methods for both input and output of chemical structures.
An interactive computer system has been designed to handle all the data associated with the National Cancer Institute's (NCI) drug screening program. The system resides on the NIH DEC System 10 computers and allows interactive access to the entire NCI screening data system. This contains over 20 separate databases, including a chemistry file of about… (More)
A small (approximately 30) but varied group of organic and inorganic compounds appear to be carcinogenic in both humans and experimental animals. A much larger number and wider variety of chemical carcinogens, primarily synthetic organic compounds, are known for experimental animals. These agents include a small (approximately 30) and varied group of… (More)
The NCI Drug Information System (DIS) is a collection of 24 interactively searchable databases which contain all the data associated with NCI's drug screening program. Data flow into all of these databases upon a daily basis, and maintenance procedures have been developed which provide a high degree of currency to the files. An extensive security system… (More)
The NCI drug screening program tests over 10,000 chemicals per year for activity against cancer. The associated Drug Information System (DIS) captures all the raw testing data and provides for its validation. The large quantity of numeric data gathered during testing is maintained within the DIS in a database that is interactively searchable and… (More)
Introduction NASA has embarked upon a Robotics Research Project at the Jet Propulsion Laboratory, the purpose of which is to establish a technology base in robotics and semi-autonomous control of unmanned machines or vehicles to support lunar and planetary exploration. The long term objective of the robotics work at JPL is to provide an integrated… (More)
