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.

Disclosed herein is a system and method for increasing the fidelity of measured genetic data, for making allele calls, and for determining the state of aneuploidy, in one or a small set of cells, or from fragmentary DNA, where a limited quantity of genetic data is available.

Objective sequence data (10) which is primary sequence information on an objective protein is entered in an interaction site predicting device by the user. A secondary structure prediction simulation is executed on the objective sequence data (10) entered for secondary structure prediction programs (20a to 20d) that predict a secondary structure of a protein from primary sequence information of the protein.

Based on the comparison result, frustration of a local portion in the primary sequence information of the objective protein is calculated (70). An interaction site of the objective protein is predicted from the calculated frustration of the local portion (80).
