  • Patent number: 11869176
    Abstract: This invention relates to a hyperspectral imaging system for denoising and/or color unmixing multiple overlapping spectra in a low signal-to-noise regime with a fast analysis time. This system may carry out Hyper-Spectral Phasors (HySP) calculations to effectively analyze hyper-spectral time-lapse data. For example, this system may carry out Hyper-Spectral Phasors (HySP) calculations to effectively analyze five-dimensional (5D) hyper-spectral time-lapse data. Advantages of this imaging system may include: (a) fast computational speed, (b) the ease of phasor analysis, and (c) a denoising algorithm to obtain the minimally-acceptable signal-to-noise ratio (SNR). An unmixed color image of a target may be generated. These images may be used in diagnosis of a health condition, which may enhance a patient's clinical outcome and evolution of the patient's health.

  • Publication number: 20240007186
    Abstract: Atmospheric turbulence degrades decoding and data recovery from optically transmitted signals. For example, atmospheric turbulence can induce power coupling from the transmitted Gaussian mode to higher-order modes, resulting in significantly degraded mixing efficiency and system performance. Systems and methods are provided to generate a signal that is a conjugate of the atmospheric noise which is combined with a received data signal to ameliorate atmospheric noise. An optical pilot beam may be transmitted with an optical data beam and received by a receiver which utilizes the optical pilot beam to generate the signal that is a conjugate of the atmospheric noise.

  • Publication number: 20230416293
    Abstract: Thymidine analogues, 5-substituted 2?-deoxy-2?-[18F]fluoro-arabinofuranosyluracil derivatives, are promising positron emission tomography (PET) tracers being evaluated for noninvasively imaging cancer cell proliferation and/or reporter gene expression. We report the radiosynthesis of 2?-deoxy-2?-[18F]fluoro-5-methyl-1-?-d-arabinofuranosyluracil ([18F]FMAU) and other 2?-deoxy-2?-[18F]fluoro-5-substituted-1-?-d-arabinofuranosyluracil analogues using 1,4-dioxane to replace the currently used 1,2-dichloroethane. Compared to 1,2-dichloroethane, 1,4-dioxane is analyzed as a better solvent in terms of radiosynthetic yield and toxicity concern. The use of a less toxic solvent allows for the translation of the improved approach to clinical production. The new radiolabeling method can be applied to an extensive range of uses for 18F-labeling of other nucleoside analogues.

  • Patent number: 11845792
    Abstract: This application provides, inter alia, antibodies or antigen-binding fragments thereof, targeting cell surface GRP78 expressed on tumor cells, tumor endothelial cells, and tumor initiating cancer cells. These anti-GRP78 antibodies, or antigen-binding fragments thereof, have a high affinity for GRP78 and are less immunogenic compared to their unmodified parent antibodies in a given species, e.g., a human, and function to inhibit GRP78. Importantly, these isolated novel antibodies and antigen-binding fragments thereof, attenuate PI3K signaling and promote apoptosis in tumor cells, while leaving normal cells unaffected. The antibodies and antigen-binding fragments are useful for UPR-targeted cancer therapeutic treatments.

  • Publication number: 20230394516
    Abstract: A federated learning environment includes a central coordinator that is responsible to orchestrate execution of the federated learning environment, and a plurality of clients jointly that trains machine learning and deep learning models on client computing devices without sharing their local private datasets. The clients only share their locally trained model parameters with the central coordinator. Model parameters are encrypted before sharing with the controller. The central coordinator aggregates local models and computes a new global model in encrypted space. This process repeats for a number of synchronization periods or asynchronously until specific convergence criteria are met. A federated learning marketplace is established to incentivize data providers to join federations through a revenue-sharing model, and to facilitate the use of machine-learning models to organizations outside of the federation.

  • Patent number: 11835524
    Abstract: A method assessing tissue morphology using machine learning includes a step of training a machine learnable device to predict the status of a diagnostic feature in stained tissue samples. The machine learnable device is trained with a characterized set of digital images of stained tissue samples. Each digital image of the characterized set has a known status for the diagnostic feature and an extracted feature map provides values for a extracted feature over an associated 2-dimensional grid of spatial locations. A step of inputting the set of extracted feature maps is inputted into the machine learnable device to form associations therein between the set of extracted feature maps to and the known status for the diagnostic feature to form a trained machine learnable device. The status for the diagnostic feature of a stained tissue sample of unknown status for the diagnostic feature is predicted from the trained machine learnable device.

  • Patent number: 11832953
    Abstract: A method for preferential system identification (PSID) for modeling neural dynamics of a brain includes extracting behaviorally relevant latent brain states via a projection of future behavior onto past neural activity. The method further includes identifying, based on the extracted latent brain states, model parameters for a linear state space dynamic model of neural activity. An extension of PSID includes accounting for an effect of external inputs to the brain by using oblique projections along the external inputs instead of orthogonal projections. PSID may be extended to apply to any primary signals and secondary signals in place of the neural activity and the behavior. In some embodiments, the extracting and the identifying may be performed using a numerical optimization of recurrent neural networks (RNN) instead of the projection.

  • Publication number: 20230381157
    Abstract: To identify novel agents to treat carbapenem-resistant Acinetobacter baumannii. the Inventors used a nutrient-depleted medium with serum to mimic the in vivo environment. In RPMI with serum, the screen identified rifabutin (RBT) as being 133-fold more potent than rifampin (RIF) against A. baumannii, with MICs of 0.031 ?g/ml and 4 ?g/ml respectively. No difference in RBT vs. RIF activity was observed when MHII was used as the culture media. RBT possesses markedly superior in efficacy to RIF in murine models of lethal iv and pneumonia models of infection with a hyper-virulent, clinical lung and blood isolate of extreme-drug resistant (XDR) A. baumannii. In both models, RBT significantly improved survival and lowered bacterial burden compared to RIF. RBT is a promising, novel therapeutic option for A. baumannii infections.
