Abstract: Acrolein is produced by selectively oxidizing iso-propanol over a first mixed metal oxide catalyst in the presence of oxygen in the vapor phase. The first mixed metal oxide catalyst comprises oxides of molybdenum and bismuth. Acrylic acid is produced by selectively oxidizing the acrolein over a second mixed metal oxide catalyst in the presence of oxygen in the vapor phase. The second mixed metal oxide catalyst has a different composition from the first mixed metal oxide catalyst.

Abstract: A user treatment engine uses user data describing characteristics of a user to evaluate a set of treatments that the user treatment engine may apply to the user. The user treatment engine generates treatment cost predictions for the treatments and generates treatment scores for the set of treatments based on the treatment cost predictions for the treatments and the user data for the user. The user treatment engine selects and applies a treatment from the set of treatments based on the generated treatment scores. The user treatment engine determines a reward to the online concierge system for the application of the treatment to the user and updates treatment selection parameters for the applied treatment based on the determined reward.

Abstract: An online concierge system receives orders from users that include items from one or more warehouses. The online concierge system identifies the orders to shoppers, who select one or more orders to fulfill. The online concierge system uses models to estimate orders likely to be received at different times and shoppers likely to be available to fulfill orders at different times. Responsive to greater than a threshold difference between estimated orders and estimated shoppers during a time interval, the online concierge system selects one or more incentives for shoppers to select orders during the time interval to entice shoppers to select orders during the time interval. An interface displayed to the shoppers by the online concierge system may present a map of warehouses and their estimated number of orders and allow shoppers to identify incentives offered for fulfilling orders at different warehouses during the time interval.

Abstract: A media system stores immersive videos and embedded affordances for each immersive video. Each embedded affordance has a temporal range, a spatial location, and a corresponding reward. A viewer selects and plays a first immersive video. While playing the first stored immersive video, the viewer navigates to different spatial portions of the first immersive video using a spatial visibility window. The viewer activates a first embedded affordance of the first immersive video according to the spatial location and temporal range of the first embedded affordance. In response, the platform initiates the reward corresponding to the first embedded affordance. The reward includes a reward token deposited into an account corresponding to the viewer. The viewer later uses a redemption user interface to redeem a plurality of reward tokens from the account (including the deposited reward token) for a single aggregated reward.

Abstract: A computing device has memory, a microphone, and an image sensor. A process plays an immersive video in a user interface region, which displays a portion of the immersive video according to a user selected visibility window. While playing the immersive video, the user adjusts the window, and the process records information that identifies placement of the window within the immersive video. The process records audio provided by the user and records video of the user. The process uses the information that identifies placement of the window to form a customized video including what was displayed in the window while playing the immersive video. The customized video also includes a visual overlay in a peripheral portion of the customized video, which includes the recorded video of the user. The customized video also includes an audio overlay using the recorded audio. The process transmits the customized video to another computer.

Abstract: A social media platform for immersive media stores immersive videos (e.g., 360 video) and embedded affordances for the immersive videos. The platform includes a publisher user interface that enables publisher users to upload immersive videos to the database and embed affordances into the immersive videos at locations that are defined both spatially and temporally. Each affordance is discoverable by viewer users, has an interactive user interface, and has one or more corresponding rewards. The platform includes a viewer user interface that enables viewer users to select and play immersive videos and navigate to different portions of a playing immersive video using a visibility window, which displays a respective selected portion of the playing immersive video based on placement of the visibility window. In response to a first user action to activate a first affordance of the playing immersive video, the platform initiates a reward corresponding to the first affordance.

Abstract: A computing system has memory, a microphone, and an image sensor. A process displays an immersive media customization user interface, and plays a 360 video. In response to a first user action, the process captures a freeze frame of the 360 video at a specific moment. In response to a second user action, the process starts recording a customized video of the captured freeze frame in real time according to a dynamically adjustable visibility window of the captured freeze frame. While recording the customized video, a user adjusts the visibility window. After recording, a user annotates the customized video, including one or more of: adding a visual overlay in a portion of the customized video, where the visual overlay is a recorded video of the user; adding an audio overlay (e.g., user comments); and adding text or an image. The process transmits the customized video to another computing system.
