  • Publication number: 20220148010
    Abstract: One embodiment provides a system for generating an inference model that determines an activity type for a user from contextual information. During operation, the system receives a set of contextual information associated with the user, wherein the contextual information includes at least a set of location coordinates. The system then determines an association between the contextual information and an activity type. Next, the system generates an activity inference model based in part on the association, wherein the activity inference model takes an instance of contextual information as an input parameter and outputs a corresponding activity type. The model's parameters are based at least on statistics associated with the user's contextual history but not based on the complete contents of the user's contextual history.

  • Publication number: 20220145311
    Abstract: Disclosed herein are novel Pichia pastoris strains for expression of exogenous proteins with substantially homogeneous N-glycans. The strains are genetically engineered to include a mutant OCH1 allele which is transcribed into an mRNA coding for a mutant OCH1 gene product (i.e., ?-1,6-mannosyltransferase, or “OCH1 protein”). The mutant OCH1 protein contains a catalytic domain substantially identical to that of the wild type OCH1 protein, but lacks an N-terminal sequence necessary to target the OCH1 protein to the Golgi apparatus. The strains disclosed herein are robust, stable, and transformable, and the mutant OCH1 allele and the ability to produce substantially homogeneous N-glycans are maintained for generations after rounds of freezing and thawing and after subsequent transformations.

  • Patent number: 11327449
    Abstract: A predictive controller controls a system under uncertainty subject to constraints on state and control variables of the system. At each control step, the predictive controller solves an inequality constrained nonlinear dynamic optimization problem including probabilistic chance constraints representing the uncertainty to produce a control command, and controls an operation of the system using the control command. The predictive controller solves the dynamic optimization problem based on a two-level optimization that alternates, until a termination condition is met, propagation of covariance matrices of the probabilistic chance constraints within the prediction horizon for fixed values of the state and control variables with optimization of the state and control variables within the prediction horizon for fixed values of the covariance matrices.
