Abstract: Described herein is a regulatory parser that downloads and efficiently processes regulatory documents. The regulatory documents may be from different sources and may have different formats. The regulatory parser parses all of the text in the regulatory documents and converts into a predetermined, single format for downstream applications. The text is organized and stored in a structured tree, organized into one or more hierarchies with nodes storing segments of text from a regulatory document. In some embodiments, each node in the regulatory tree may represent a segment of text. Partitioning the text of a regulatory document into segments of text may make the storage and querying of the regulatory documents more manageable. The organization and structure of the structured tree may reduce the times and resources needed for accessing and searching for a regulatory citation. The structured tree may allow a user to manipulate a regulatory document or text.

Abstract: A corpus of source code from a code database is accessed and a language prediction model is trained based on the corpus of source code. A given program is accessed and a completion of a given line of the given program is predicted by performing inferencing using the language prediction model and at least a portion of the given program. The given line is completed based upon the prediction.

Abstract: The present invention relates to a method of grading the nuclear morphology of a tumor cell. The method may comprise a) culturing the tumor cell on an array comprising a plurality of nanopillars; and b) assessing a deformation pattern of the nucleus, wherein an isotropic deformation indicates low malignancy of the tumor cell, while a linear or anisotropic deformation pattern indicates high malignancy of the tumor cell. In another embodiment, the method comprises determining a nanopillar-induced deformation profile comprising an angular distribution of orientations in a plurality of regions of interests (ROIs) of the image and a coherency in each ROI. The invention also relates to a method of predicting the likelihood of a metastatic cancer or predicting a response of a tumor to a cancer drug in a subject based on assessing the degree of nuclear deformation of a cell sample cultured on the surface comprising a plurality of nanopillars.

Abstract: Provided herein is a method for manipulating the surface density of functional molecules conjugated to nanoparticles, which method including incubating nanoparticles with nucleotides to form nucleotide-coated nanoparticles, adjusting buffer and salt concentration of the conjugation media, adding thiolated molecules in the conjugation media to incubate with the nucleotie-coated nanoparticles, and adding thiolated oligo(ethylene glycol) in the conjugation media to cease the conjugation process of thiolated molecules to nanoparticles. The method is simple, efficient and cost effective, and the surface density of functional molecules can be quickly manipulated in a wide range for various applications, such as biosensing, molecular diagnostics, nanomedicine, and nano-assembly.
