چکیده
BDB is developed atin the Institute of Astronomy RAS, and contains information on physical and positional parameters of binary stars, belonging to various observational types: visual, spectroscopic, eclipsing, etc. Problems of information aggregation on binaries of various types binaries (obtained from heterogeneous sources of data astronomical catalogues and surveys) aggregation in a uniquefied database are considered in the paper. Database structure, principles of data transformation from original catalogs’ formats into the BDB format, as well as basic cross-identification methods for multi-source objects are also described .

Astronomical Data Resources for Binary and Multiple Stars
Binary stars form a significant part of stellar population. They are registered and observed by a number of methods. This is the reason for variety of present-day resources of astronomical data dealing with binaries and multiples. The review of observational types of binary stars and of basic data resources for them is presented. The properties of stars within these types and possible relations...
متن کاملNRLiSt BDB, the manually curated nuclear receptors ligands and structures benchmarking database.
Nuclear receptors (NRs) constitute an important class of drug targets. We created the most exhaustive NR-focused benchmarking database to date, the NRLiSt BDB (NRs ligands and structures benchmarking database). The 9905 compounds and 339 structures of the NRLiSt BDB are ready for structure-based and ligand-based virtual screening. In the present study, we detail the protocol used to generate th...
متن کاملAn Efficient 3D Optical Implementation of Binary de Bruijn Networks with Applications to Massively Parallel Computing
As an alternative t o the hypercube, the binary d e Bruijn BdB network is recently receiving rithmic diameter, fault-tolerance, and simple routing but also requires fewer links than the hypercube for the same network size. Additionally, a major advantage of the BdB network is a constant node degree: the number of edges per node is independent of the network size. This makes it very desirable fo...
متن کاملBDB: biopanning data bank
The BDB database (http://immunet.cn/bdb) is an update of the MimoDB database, which was previously described in the 2012 Nucleic Acids Research Database issue. The rebranded name BDB is short for Biopanning Data Bank, which aims to be a portal for biopanning results of the combinatorial peptide library. Last updated in July 2015, BDB contains 2904 sets of biopanning data collected from 1322 pee...
متن کاملAn E cient 3 D Optical Implementation of Binary de Bruijn Networks with Applications to Massively Parallel Computing 1
The interconnection network structure can be the deciding and limiting factor in cost and performance of parallel computers. One of the most popular point-to-point interconnection networks for parallel computers today is the hypercube. The regularity, logarithmic diameter, symmetry, high connectivity, fault-tolerance, simple routing, and recon gurability (easy embedding of other network topolog...
