  • Patent number: 11151120
    Abstract: There are provided systems and methods for determining data validity during data processing for multiple processing stacks. During processing requests with a service provider, each request may go through a data flow that invokes multiple processing stacks, where the data is transmitted over a network to different data processing nodes. For example, a distributed computing architecture may invoke multiple disparate nodes to process data, which may become corrupted during data transmission and processing. To ensure data validity, a framework may be provided that provided data translators for each processing stack to covert data handled in a processing format for that stack into a base data format utilized by the framework. The framework may utilize checksums or other hash values of the data in the base data format to determine if the data has been altered at different processing nodes or stacks.

  • Patent number: 11093310
    Abstract: Systems, methods, and computer program products for identifying a data pattern change anomaly uses a distributing computing environment that processes thousands of different data flows are provided. Numerous data flows are collected from the application computing environment over a configurable time period. The flows are aggregated into aggregated data according to at least one attribute from the flows and without losing information included in the flows. Historical data that includes aggregated data from multiple flows that occurred prior to a time during which the numerous data flows were collected is provided from a distributed disk storage. An anomaly that indicates change in data patterns in the flows is identified by comparing the aggregated data to the historical data using one or more models that are tailored to the numerous flows. An alert that includes an anomaly and a reason for an anomaly is transmitted and recorded in the system.

  • Patent number: 8338119
    Abstract: The invention relates to chondroitinase ABC I and uses thereof. In particular, the invention relates to recombinant and modified chondroitinase ABC I, their production and their uses. The chondroitinase ABC I enzymes of the invention are useful for a variety of purposes, including degrading and analyzing polysaccharides such as glycosaminoglycans (GAGs). These GAGs can include chondroitin sulfate, dermatan sulfate, unsulfated chondroitin and hyaluronan. The chondroitinase ABC I enzymes can also be used in therapeutic methods such as promoting nerve regeneration, promoting stroke recovery, treating spinal cord injury, treating epithelial disease, treating infections and treating cancer.

  • Publication number: 20120135049
    Abstract: Methods for producing tissue engineered constructs and engineered native tissues include producing a tissue engineered construct by growing cells in vitro on a substrate and then decellularizing the construct to produce a decellularized construct consisting largely of extracellular matrix components. The construct can be used immediately or stored until needed. The decellularized construct can be used for further tissue engineering, which may include seeding the construct with cells obtained from the intended recipient of the construct. During any of the growth phases required for production of the construct, the developing construct may be subjected to various tissue engineering steps such as application of mechanical stimuli including pulsatile forces.
