  • Patent number: 11983216
    Abstract: In some embodiments, apparatuses and methods are provided herein useful to automatically annotating images. In some embodiments, a system for automatically annotating images comprises a database, wherein the database is configured to store images and annotations for the images and a control circuit, wherein the control circuit is communicatively coupled to the database, and wherein the control circuit is configured to retrieve, from the database, an image, generate, based on the image, a collection of augmented images, generate segmentation maps for each image in the collection of augmented images, wherein each of the segmentation maps include segments, select, based on a threshold, ones of the segments above a threshold, merge the ones of the segments above the threshold to create a segmented image, and generate, for each segment of the segmented image, classifications, wherein an annotation for the image includes the segmented images and the classifications.

  • Publication number: 20230203544
    Abstract: Controlled coenzyme Q10 (CoQ10) fermentation production processes and methods for controlling the CoQ10 fermentation production processes are provided in the present disclosure. The processes may include growing a microbial culture of bacteria by providing a carbon source and an oxygen source for a predetermined period of time, thereby producing CoQ10-containing bacteria, carbon dioxide, and lactate in the bacterial culture. During various stages of the production process, the concentration of carbon dioxide may be maintained at predetermined levels, respectively. Alternatively or additionally, during various stages of the production process, the concentration of lactate may be maintained at predetermined levels, respectively.

  • Publication number: 20230203545
    Abstract: A method for controlled production of glyceric acid includes, during the glyceric acid fermentation process, real-time online monitoring of at least one of the respiratory quotient and redox potential in the fermentation liquid as well as the fermentation process specific growth rate, and controlling their values within the following ranges: 0.1˜1.5 for respiratory quotient, ?300˜50 mV for redox potential, 0.05˜0.8 for specific growth rate. Process parameters for this method are controlled within predetermined ranges by online monitoring at least one of respiratory quotient (RQ) and redox potential as well as the specific growth rate in the fermentation process, thereby meeting the growth requirements of bacteria, effectively promoting the glycerol metabolism and synthesis and improving the conversion rate.
