  • System and method for generating a dataset for real noise reduction evaluation
    Patent number: 9591240
    Abstract: The present invention provides a system and method for generating a dataset of uncompressed color images taken with three digital cameras and exhibiting different levels of real noise, resulting from low-light conditions. For each scene there are, on average, two low-noise and two noisy images that are aligned at the pixel level both spatially and in intensity. In one embodiment, the dataset contains over 100 scenes and more than 400 images, including both 16-bit RAW formatted images and 8-bit BMP pixel and intensity aligned images from three digital cameras. The generated dataset of real noise images is useful in the evaluation of denoising algorithms.

  • Polymer ligands for nanoparticles
    Patent number: 9580560
    Abstract: The disclosure is directed to polymer ligands that are optimally suited for surface-functionalizing magnetic nanoparticles. The amphiphilic polymers are prepared by coupling several amine-terminated anchoring groups, polyethylene glycol moieties, and reactive groups onto a poly(isobutylene-alt-maleic anhydride) (PIMA) chain. The reaction of maleic anhydride groups with amine-containing molecules is highly-efficient and occurs in one-step. The availability of several dopamine groups in the same ligand greatly enhances the ligand affinity, via multiple-coordination, to the magnetic NPs, while the hydrophilic and reactive groups promote colloidal stability in buffer media and allow subsequent conjugation with target biomolecules. Nanoparticles ligated with terminally reactive polymers have been easily coupled to target dyes and tested in live cell imaging with no measurable cytotoxicity.

  • Stereo controlled synthesis of ()-dienals via tandem Rh(I) catalyzed propargyl claisen rearrangement
    Patent number: 9573871
    Abstract: A novel Rh(I)-catalyzed approach to synthesizing functionalized (E,Z) dienal compounds has been developed via tandem transformation where a stereoselective hydrogen transfer follows a propargyl Claisen rearrangement. Z-Stereochemistry of the first double bond suggests the involvement of a six-membered cyclic intermediate whereas the E-stereochemistry of the second double bond stems from the subsequent protodemetallation step giving an (E,Z)-dienal. The reaction may be represented by the following sequence.

  • Method for identifying cells based on DNA replication domain timing profiles
    Patent number: 9574231
    Abstract: Methods for identifying and/or distinguishing a homogeneous population of cells based on their replication domain timing profile using high resolution genomic arrays or sequencing procedures are provided. These methods may be used to compare the replication timing profile for a population of cells to another replication timing profile(s), a replication timing fingerprint, and/or one or more informative segments of a replication timing fingerprint, which may be simultaneously or previously determined and/or contained in a database, to determine whether there is a match between them. Based on such information, the identity of the population of cells may be determined, or the identity of the population of cells may be distinguished from other populations of cells or cell types. Methods for determining a replication timing fingerprint for particular cell types are also provided.

  • Method for small-signal stability assessment of power systems using simultaneous source side and load side perturbations
    Patent number: 9575139
    Abstract: A novel method for real-time small-signal stability analysis for power electronic-based components in a power system. The method may be used to monitor a power system in real-time by perturbing the source side of an electronic-based component of the power system by injecting a current of about 0.5 to 1 percent of a nominal current of the power system at the source side, while simultaneously perturbing the load side of the power electronic-based component by varying the voltage at the load side. Time-domain results of the simultaneous perturbations may be transferred to frequency-domain results and the stability of the power system may be monitored by obtaining a Nyquist contour and employing Generalized Nyquist Criterion or unit circle criterion.

  • Automated extraction of bio-entity relationships from literature
    Patent number: 9542528
    Abstract: Automated, standardized and accurate extraction of relationships within text. Automatic extraction of such relationships/information allows the information to be stored in structured form so that it can be easily and accurately retrieved when needed. Such information can be used to build online search engines for highly specific and accurate information retrieval. Generally, according to the current invention, extracting such information (i.e., relationships within text) from raw text can be accomplished using natural language processing (NLP) and graph theoretic algorithm. Examples of such textual relationships include, but are not limited to, biological relationships between biological terms such as proteins, genes, pathways, diseases and drugs. The current methodology is also able to recognize negative dependences in context, match patterns, and provide a shortest path between related words.

  • System and methods for analyzing and modifying passwords
    Patent number: 9524393
    Abstract: A system for analyzing and modifying passwords in a manner that provides a user with a strong and usable/memorable password. The user would propose a password that has relevance and can be remembered. The invention would evaluate the password to ascertain its strength. The evaluation is based on a probabilistic password cracking system that is trained on sets of revealed passwords and that can generate password guesses in highest probability order. If the user's proposed password is strong enough, the proposed password is accepted. If the user's proposed password is not strong enough, the system will reject it. If the proposed password is rejected, the system modifies the password and suggests one or more stronger passwords. The modified passwords would have limited modifications to the proposed password. Thus, the user has a tested strong and memorable password.

  • Structurally reinforced optically transparent bulletproof panel
    Patent number: 9494389
    Abstract: A structurally reinforced optically transparent panel that may be utilized as a bulletproof window or shield. The panel includes a plurality of angled reinforcement members having a reflective top and bottom surfaces. Optical lenses are disposed between the reinforcement members directing a light ray in a predetermined direction. The geometry and spacing of the reinforcement members is such that the light rays enter and exit the bulletproof panel at substantially the same angle allowing an observer to view optical images of objects behind the bulletproof panel, thus creating optical transparency. The reinforcement members are of a high strength material capable of being impenetrable by a projectile fired from a ballistic weapon or an explosion debris.
