Abstract: The design and characteristics of orthonormal two-band QMF filter banks, with perfect reconstruction and linear phase properties, are considered in this paper. The analysis and synthesis filter banks are implemented using allpass filters. Filters in the synthesis bank are anticausal and unstable filters and the block processing technique and an appropriate causal filter are applied fo...

We at the DNA Data Bank of Japan (DDBJ) (http://www.ddbj.nig.ac.jp) have recently begun receiving, processing and releasing EST and genome sequence data submitted by various Japanese genome projects. The data include those for human, Arabidopsis thaliana, rice, nematode, Synechocystis sp. and Escherichia coli. Since the quantity of data is very large, we organized teams to conduct preliminary d...

There is an increasing realisation that the quality of the biomacromolecular structures deposited in the Protein Data Bank (PDB) archive needs to be assessed critically using established and powerful validation methods. The Worldwide Protein Data Bank (wwPDB) organization has convened several Validation Task Forces (VTFs) to advise on the methods and standards that should be used to validate al...

In this paper we present a novel method to describe the pose (position and orientation) distribution of amino acid residue pairs within a protein, which are proximal in space and distal in sequence.While the Ramachandran plot provides information of protein conformations using the φ and ψ angles between sequentially proximal residues, our method can offer six-dimensional relative pose informati...

In the early 1990s, Taiwan began her deregulation trend in order to enhance competition and economic efficiency across all industries. We derive a theoretical framework to predict possible rankings in technical efficiencies of public, mixed, and private banks. A panel data set with 43 Taiwanese banks during 1997-1999 is used for empirical analysis. We then apply a translog distance function to ...

Many studies have used position-specific scoring matrices (PSSM) profiles to characterize residues in protein structures and to predict a broad range of protein features. Moreover, PSSM profiles of Protein Data Bank (PDB) entries have been recalculated in many works for different purposes. Although the computational cost of calculating a single PSSM profile is affordable, many statistical studi...

A great deal of system and human effort is expended to collect detailed technical measurements. These measurements are usually stored in some form of a Performance Database, or PDB. However, these data do little to help us understand the purpose of those systems: supporting our business. These basic performance measures tell us very little about the systems’ business value. To understand that b...

UNLABELLED To aid detailed comparison of a large number of macromolecular structures, Resmap imports Protein Data Bank files and represents subunit/domain interfaces as two-dimensional networks. AVAILABILITY http://www.kumc.edu/biochemistry/resmap/. SUPPLEMENTARY INFORMATION Default definitions and directions for graphically managing networks are available at the same website.

The performance database (PDB) stores performance-related data gathered during workflow enactment. We argue that, by carefully understanding and manipulating these data, we can improve efficiency when enacting workflows. This paper describes the rationale behind the PDB, and proposes a systematic way to implement it. The prototype is built as part of the Advanced Data Mining and Integration Res...

Because poorly developed financial markets block economic growth, it is argued that modern intermediaries (banks) have to replace traditional intermediaries. The claim is that the traditional intermediaries are inefficient. We test that claim using an original panel data set from nineteenthcentury France that is the first to provide quantitative evidence about traditional intermediaries (notari...
