摘要： A method and system for multi-scale anatomical and functional modeling of coronary circulation is disclosed. A patient-specific anatomical model of coronary arteries and the heart is generated from medical image data of a patient. A multi-scale functional model of coronary circulation is generated based on the patient-specific anatomical model. Blood flow is simulated in at least one stenosis region of at least one coronary artery using the multi-scale function model of coronary circulation. Hemodynamic quantities, such as fractional flow reserve (FFR), are computed to determine a functional assessment of the stenosis, and virtual intervention simulations are performed using the multi-scale function model of coronary circulation for decision support and intervention planning.

摘要： A mechanical property of anatomy is estimated from a patient in vivo, such as estimating a patient-specific material property of a valve. A morphological model is used to determine anatomy dynamics. A biomechanical model, using the anatomy dynamics, predicts the dynamics, based, at least in part, on one or more material properties. Using an inverse solution based on comparison of dynamics predicted by the biomechanical model and the dynamics determined from the morphological model, values for the material properties are determined.

摘要： A method for modeling blood flow through a flow diverter includes receiving a medical image containing blood vessels. Vessel geometry is extracted from the received medical image. Inlets and outlets are tagged within the extracted vessel geometry. A desired flow diverter is selected. A model of the selected flow diverter is generated within the imaged blood vessel, the model representing the flow diverter as a tube having a porous surface characterized by a viscous resistance and an inertial resistance. A course of blood flow though the flow diverter is predicted based on the generated model, the extracted vessel geometry, and the tagged inlets and outlets.

摘要： A method includes preferentially placing fill regions adjacent to transistors of a particular conductivity type, such as p-channel transistors, for a plurality of standard cell instances of a device design. The method also includes evaluating all transistors of the first conductivity type prior to evaluating any transistors of a second conductivity type. The second conductivity type is opposite the first conductivity type. For each transistor being evaluated, it is determined whether a criterion is me. A fill region is placed within a field isolation region adjacent to the transistor if the criterion is met.

摘要： A plurality of data flows can be routed from a first node of the network to one or more other nodes of the network. A destination of a data packet for each data flow is determined. When the destination node of the data packet of that data flow is not adjacent to the first node, a probabilistic determination is made for a next hop of data packets of that data flow. When the destination node of the data packet of that data flow is adjacent to the first node, a priority designation is made for the next hop of data packets of that data flow as being the destination node. The next hop for data packets of the data flow is determined based on either the probabilistic determination or the priority designation.

摘要： Route discovery for an end-to-end path in a network is performed for a flow. A path is attempted to be discovered that satisfies QoS constraints for multiple metrics for the flow. The route discovery includes determining whether a path request for a path satisfying the QoS constraints is feasible, infeasible or undecideable based on information in a local QoS table. If the path request is determined to be undecideable, route discovery is performed with neighbors.
