  • Patent number: 10017724
    Abstract: A microfluidic device for more accurately modeling the in vitro environment in which cancer occurs is disclosed. The device comprises a surface defining one or more microfluidic channels that may further comprise one or more endothelial cells, a first three dimensional scaffold comprising one or more cancer cells that is spatially separated from the one or more microfluidic channels, and a second three dimensional scaffold comprising one or more stromal cells, at least a portion of which is interposed between the one or more microfluidic channels and the first three dimensional scaffold. The second three dimensional scaffold is in fluid communication with both the first three dimensional scaffold and the one or more microfluidic channels. The device can be used to assay anti-cancer agents, or as a system for modeling the growth, behavior, or metastasis and tumor formation of cancer cells.

  • Publication number: 20180137412
    Abstract: A server uses an LSTM neural network to predict a bandwidth value for a computer network element using past traffic data. The server receives a time series of bandwidth utilization of the computer network element. The time series includes bandwidth values associated with a respective time values. The LSTM neural network is trained with a training set selected from at least a portion of the time series. The server generates a predicted bandwidth value associated with a future time value based on the LSTM neural network. The provisioned bandwidth for the computer network element is adjusted based on the predicted bandwidth value.

  • Publication number: 20170067025
    Abstract: A method for creating a tumor model includes encapsulating cancer cells in a first solution, disposing the first solution on a spacer, cross-linking the first solution and creating one or more high stiffness constructs, disposing a second solution around the one or more high stiffness constructs, and cross-linking the second solution and creating a low stiffness matrix surrounding the one or more low stiffness constructs.

  • Patent number: 7190141
    Abstract: A modular exoskeletal device adapted to fit the lower extremities of a patient during rehabilitation. The device has only two actuators during the standing stage of rehabilitation. Two additional actuators can be added, as modules, during the walking stage of rehabilitation. The actuators are affixed to the patient and provide controlled motion to at least one of the joints of the patient. A stationary control unit is separated from the patient. The control unit communicates with and directs the actuators, and has a hybrid control algorithm, such that the actuator forces are adjusted as the patient regains control of some joint motions, which is based upon the sliding-mode control theory. A back brace is affixed to the patient and helps to keep the torso of the patient in a stable, substantially vertical position.
