Abstract: A method and apparatus for radiation therapy using functional measurements of branching structures. The method includes determining a location of each voxel of a plurality of voxels in a reference frame of a radiation device. The method further includes obtaining measurements that indicate a tissue type at each voxel. The method further includes determining a subset of the voxels based on an anatomical parameter of a respective branching structure of a set of branching structures indicated by the measurements. The method further includes determining a subset of the voxels that enclose an organ-at-risk (OAR) volume. The method further includes determining a value of a utility measure at each voxel. The method further includes determining a series of beam shapes and intensities which minimize a value of an objective function based on a computed dose delivered to each voxel and the utility measure for that voxel summed over all voxels.

Abstract: Various face discrimination systems may benefit from techniques for providing increased accuracy. For example, certain discriminative face verification systems can benefit from L2-constrained softmax loss. A method can include applying an image of a face as an input to a deep convolutional neural network. The method can also include applying an output of a fully connected layer of the deep convolutional neural network to an L2-normalizing layer. The method can further include determining softmax loss based on an output of the L2-normalizing layer.

Abstract: This invention is a computer-implemented method and system of using a secondary classification algorithm after using a primary source code vulnerability scanning tool to more accurately label true and false vulnerabilities in source code. The method and system use machine learning within a 10% dataset to develop a classifier model algorithm. A selection process identifies the most important features utilized in the algorithm to detect and distinguish the true and false positive findings of the static code analysis results. A personal identifier is used as a critical feature for the classification. The model is validated by experimentation and comparison against thirteen existing classifiers.

Abstract: Metastatic triple negative breast cancer (TNBC) still carries a dismal prognosis with the current treatment paradigms. The effectiveness of drug treatment for many solid tumors such as TNBC is limited by tumor heterogeneity, lack of tumor specificity, off-target toxicities, and transient therapeutic action(s). Strategies that provide tumor-specific, sustained concentrations of drugs to the tumors and tumor receptor-specific binding, while reducing off-target effects are needed to ensure sufficient tumor cell uptake within the primary and metastatic tumor microenvironment. The decreased non-specific adhesivity, receptor-targeted nanoparticle formulations (“DART” nanoparticles) of the invention were assessed for clinical potential in directing biological agents to the cell surface receptor Fn14, which is expressed in many solid cancer types, including TNBC primary tumors and metastatic lesions.

Abstract: The present invention provides improved devices for co-culture of cells. The devices include inserts having invertible wells that can be lowered into a well of any standard cell culture plate. A first population of cells can be cultured in the invertible wells of the inserts and a second population of cells can be cultured in the wells of a cell culture plate. Once the first population of cells attach to the invertible wells, the inserts are flipped over and placed into the wells of the cell culture plate to co-culture with the second population of cells.
