Abstract: Systems and methods for precomputing data and storing cache objects corresponding to the precomputed data are described. A system creates a new cache object when a user interacts with the system. The system precomputes formulas in the newly created cache object by replacing the formulas with corresponding calculated values. The system precomputes the formulas in the background (i.e., the user is not presented with the precomputed values while the user is manipulating the data). The system may persistently store a precomputed version cache object in a dedicated version cache storage for later use. If updates are performed to the structure and/or values of a version represented in a precomputed version cache object, effected parts of the version cache object are invalidated by replacing calculated values with the underlying formulas.

Abstract: A method for creating and exchanging a copyright for each artificial intelligence (AI)-generated multimedia is described. An AI model and a reference input for a multimedia is received from a user. If the reference input complies with system policies, an AI-generated multimedia is generated from the reference input using the AI model. The AI-generated multimedia is compared against works of a same type in a blockchain and decentralized file storage and if the AI-generated multimedia fails to match the works, the AI-generated multimedia is categorized as having originality. A copyright for the AI-generated multimedia and the AI-generated multimedia is stored. An exchange is facilitated with a buyer using cryptocurrency and is written to a blockchain.

Abstract: Rapid methods that identify sepsis-causing bacteria or yeast aid the physician in critical therapeutic decision-making, thus decreasing patient mortality rates. The methods described herein employ plating microorganisms directly on to a MALDI-MS plate, adding concentrated formic acid, and identifying the microorganism by mass spectrometry. Optionally, an organic solvent may be combined with the formic acid, or added to the sample before or after the concentrated formic acid is added thereto. The methods enable direct extraction of proteins from microorganisms without the need for liquid protein extraction methods and yields positive identification results for gram-positive bacteria, gram-negative bacteria and yeast in minutes.
