  • Publication number: 20240070400
    Abstract: Method of analysis text message syntactically and by content, which entails: step 1; Split syntaxes (made available to subscribers by the network operator) into tokens to store in a Syntax Trie; step 2. Pre-process an incoming text from a subscriber; step 3. Split the text (pre-processed in Step 2) into tokens; step 4. Look up paths that include the tokens (obtained in Step 3) in the Syntax Trie (initialized in Step 1); step 5: Return the look-up result, which is the path in the Syntax Trie that best reflects the user intent.

  • Publication number: 20220362401
    Abstract: Particles using a polymer having a particle size suitable for a drug delivery system (DDS) or the like are provided. A drug and an anti-cancer agent using the particles are provided. Each of the particles comprises a polymer having a structure unit derived from a saccharide compound having a hydroxyl group and having an inclusion property and a structure unit derived from a monomer having a functional group to be reacted with a hydroxyl group, and has the average hydrodynamic radius (Rhav) of 5 to 100 nm. A method for producing the particles comprises a step of mixing a mixed composition comprising a saccharide compound, a monomer, a surfactant, and an alkaline aqueous solution having a pH of 12 or more. A drug compress a hydrophobic physiological active agent, such as ?-mangostin contained in the particle, and an anti-cancer agent comprising the drug.

  • Patent number: 10729079
    Abstract: A microgravity agriculture device includes a root cylinder providing a growing medium for the plant and intended for root growth. The root cylinder will extend into a water tank, and the root cylinder will include apertures and wicking elements to draw water from the water tank into the root cylinder for availability to the plant roots. The geometries of the water tank, root cylinder, apertures and wicking elements are designed in a manner to ensure water surface tension will cause water in the tank to fill and stay in the proper areas to ensure water flow to the plant, no obstruction of vents during tank filling, and no egress of the water through the vents.
