    摘要： An intrusion detection system for a computer network includes a knowledge database that contains a baseline of normal host behavior, and a correlation engine that monitors network activity with reference to the knowledge database. The correlation engine accumulating information about anomalous events occurring on the network and then periodically correlating the anomalous events. The correlation engine generates a worm outbreak alarm when a certain number of hosts exhibit a role-reversal behavior. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    摘要： The invention provides a self-assembling peptide comprising (a) a first amino acid domain that mediates self-assembly, wherein the domain comprises alternating hydrophobic and hydrophilic amino acids that are complementary and structurally compatible and self-assemble into a macroscopic structure when present in unmodified form; and (b) a second amino acid domain that does not self-assemble in isolated form. In certain embodiments of the invention the second amino acid domain comprises a biologically active peptide motif, e.g., a peptide motif found in a naturally occurring protein, or a target site for an interaction with a biomolecule. In certain embodiments of the invention the naturally occurring protein is a component of the extracellular matrix, e.g., a component of the basement membrane. The invention further provides scaffolds comprising the self-assembling peptides and methods of using the scaffolds including for cell culture, tissue engineering, and tissue repair.

    摘要： Described herein is the self-assembly of amphiphilic peptides, i.e., peptides with alternating hydrophobic and hydrophilic residues, into macroscopic membranes. The membrane-forming peptides are greater than 12 amino acids in length, and preferably at least 16 amino acids, are complementary and are structurally compatible. Specifically, two peptides, (AEAEAKAK)2 (ARARADAD)2, were shown to self-assemble into macroscopic membranes. Conditions under which the peptides self-assemble into macroscopic membranes and methods for producing the membranes are also described. The macroscopic membranes have several interesting properties: they are stable in aqueous solution, serum, and ethanol, are highly resistant to heat, alkaline and acidic pH, chemical denaturants, and proteolytic digestion, and are non-cytotoxic. The membranes are potentially useful in biomaterial applications such as slow-diffusion drug delivery systems, artificial skin, and separation matrices, and as experimental models for Alzheimer's disease and scrapie infection. The sequence of the peptide, EAK16, was derived from a putative Z-DNA binding protein from yeast, called zuotin. The cloning and characterization of the ZUO1 gene are also described.
