Abstract: A container has a product in a product-receiving area and has a sealing area surrounding the product-receiving area. A length of film is arranged over the container. A space above the film is evacuated using an evacuating portion of an upper sealing module arranged over the film, so as to cause a portion of the film to conform to the upper sealing module. An area of the film is cut out by moving a cutting tool relative to the upper sealing module from a recessed position to a cutting position. The cut-out area of film includes the portion of the film conformed to the upper sealing module, is brought into contact with the sealing area of the container by moving the upper sealing module relative to the container, and is sealed to the sealing area of the container using a heat sealing portion of the upper sealing module.

Abstract: Lubricating oil compositions are provided which contain bimodal copolymer compositions, and in particular bimodal ethylene-?-olefin copolymer compositions. The copolymer compositions comprise first and second ethylene-?-olefin copolymer components. The bimodal compositions are particularly useful as viscosity or rheology modifiers, e.g., in lubricating oil compositions. Lubricating oil compositions comprising the copolymer compositions advantageously exhibit enhanced shear stability index (SSI) and thickening efficiency (TE) values, while maintaining excellent low-temperature properties such as pour point, mini-rotary viscometer viscosity, and cold crank simulation performance.

Abstract: Various embodiments of the present disclosure disclose methods and systems for heat exchange in an opto-fluidic instrument. The opto-fluidic instrument includes a sample interface module (SIM), an illumination module, a camera module, and a reagent deck. A coolant from a coolant reservoir is directed into one or more of the modules so that heat exchange occurs at each module with the coolant. The heated coolant from the one or more modules flows to a radiator for cooling, for example, with fans flowing ambient air over the radiator, before the cooled coolant is returned to the coolant reservoir for subsequent use in cooling the modules.

Abstract: A feature engineering engine is included in an analytics application provided to at least one subscriber from a plurality of subscribers. The feature engineering engine generates a reduced discovery dataset based on an input dataset and stores at least a portion of the reduced discovery dataset in cache memory associated with the analytics application. While displaying at least a portion of the reduced discovery dataset, the feature engineering engine performs one or more entity resolution operations and generates an instantiated set of features. In some embodiments, the instantiated set of features is generated based on a previously generated, reusable feature definition. In some embodiments, using the instantiated set of features, a trained machine learning model is automatically selected from a plurality of models based on a performance metric determined for the instantiated set of features.
