Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed for teacher-free self-feature distillation training of machine-learning (ML) models. An example apparatus includes at least one memory, instructions, and processor circuitry to at least one of execute or instantiate the instructions to perform a first comparison of (i) a first group of a first set of feature channels (FCs) of an ML model and (ii) a second group of the first set, perform a second comparison of (iii) a first group of a second set of FCs of the ML model and one of (iv) a third group of the first set or a first group of a third set of FCs of the ML model, adjust parameter(s) of the ML model based on the first and/or second comparisons, and, in response to an error value satisfying a threshold, deploy the ML model to execute a workload based on the parameter(s).

Abstract: The present invention relates to the field of solid-phase extraction, and particularly to a solid-phase extraction material, and a preparation method and use thereof. The preparation method includes prepolymerizing the monomers N-vinylpyrrolidone and divinylbenzene in the presence of a chain transfer agent, adding prepolymer dropwise to an emulsion of monodispersed seed microspheres, swelling, and reacting to prepare white spheres; and functionalizing the white spheres, to obtain the solid-phase extraction material. The solid-phase extraction material prepared by the reaction has good spherical morphology, large specific surface area, and high ion exchange capacity. The prepared solid-phase extraction material functions in the separation and enrichment of PPCPs by means of a variety of forces with a high extraction rate. The extraction rate is basically maintained between 85% and 105%, and acidic, alkaline, neutral and amphoteric substances is capable of being selectively separated.

Abstract: The application discloses a system and method for centrifugal intrusion of molten metal into porous media and then solidification positioning, including: test cups, used for placing test medium and molten metal intrusion; a rotor block, used for mounting the test cups, where one end of each test cup for placing the test medium is far away from the rotor block; a constant temperature oil bath preheating device, used for preheating the test cups and the rotor block; a centrifugal device, internally provided with the rotor block, used for performing a centrifugal operation on the test cups, where the test cups and the rotor block are installed inside the centrifugal device after being preheated; and an infrared heating and compression refrigerating device, arranged inside the centrifugal device, used for controlling a temperature of the test cups.

Abstract: An enteric-coated pellet, a method for preparing the same and a formulation comprising the same are provided. The enteric-coated pellet can be an ilaprazole enteric-coated pellet.

Abstract: The present invention relates to a pharmaceutical composition containing ilaprazole or a salt thereof, and a preparation method therefor. The pharmaceutical composition contains or consists of ilaprazole or a salt thereof, and a ilaprazole derivative, wherein the amount of the ilaprazole derivative in the pharmaceutical composition is not higher than 1.3 wt % (less than or equal to 1.3 wt %). The composition can be used for treating peptic ulcer bleeding and stress ulcer and preventing upper gastrointestinal hemorrhage caused by severe diseases.
