ready Joint Photographic Experts Group Format

Abbreviation: JPEG Format


General Information
Joint Photographic Experts Group Format is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. JPEG JFIF, which is what people generally mean when they refer to "JPEG", is a file format created by the Independent JPEG Group (IJG) for the transport of single JPEG-compressed images. The JPEG compression format was standardised by ISO in August 1990 and commercial applications using it began to show up in 1991. The widely used IJG implementation was first publicly released in October 1991 and has been considerably developed since that time. JPEG JFIF images are widely used on the Web. The amount of compression can be adjusted to achieve the desired trade-off between file size and visual quality. Progressive JPEG is a means of reordering the information so that, after only a small part has been downloaded, a hazy view of the entire image is presented rather than a crisp view of just a small part. It is part of the original JPEG specification, but was not implemented in Web browsers until rather later on, around 1996. It is now fairly widely supported. Although the "baseline" variety of JPEG is believed patent-free, there are many patents associated with some optional features of JPEG, namely arithmetic coding and hierarchical storage. For this reason, these optional features are never used on the Web.

Implementing Databases (7)
Bitter Compounds Database
BitterDB is a free and searchable database of bitter compounds. Compounds can be searched by name, chemical structure, similarity to other bitter compounds, association with a particular human bitter taste receptor, and so on. The database also contains information on mutations in bitter taste re- ceptors that were shown to influence receptor activation by bitter compounds. The aim of BitterDB is to facilitate studying the chemical features associated with bitterness.
Dragon Antimicrobial Peptide Database
Dragon Antimicrobial Peptide Database is a manually curated database of known and putative antimicrobial peptides (AMPs). It covers both prokaryotes and eukaryotes organisms.
EcoliWiki: A Wiki-based community resource for Escherichia coli
Community-based resource for the annotation of all non-pathogenic E. coli, its phages, plasmids, and mobile genetic elements.
Plantmetabolomics.org
Arabidopsis metabolomics database which provides researchers with resources to investigate the function of genes and metabolites.
RNA Characterization of Secondary Structure Motifs
RNA Characterization of Secondary Structure Motifs (RNA CoSSMos) database allows the systematic searching of all catalogued three-dimensional nucleic acid PDB structures that contain secondary structure motifs such as mismatches, (a)symmetric internal loops, hairpin loops, and bulge loops.
Nematode.net
Nematode.net is the home page of the parasitic nematode EST project at The Genome Institute at Washington University in St. Louis. The site was established in 2000 as a component of the NIH-NIAID grant "A Genomic Approach to Parasites from the Phylum Nematoda". While Nematode.net started as a project site, over the years it became a community resource dedicated to the study of parasitic nematodes.
SuperTarget
Drug-related information: medical indications, adverse drug effects, drug metabolism and Gene Ontology terms of the target proteins.
