This invention discloses a method for evaluating and training language model prompt word sensitivity based on symbolic interaction, belonging to the field of natural language processing technology. It addresses the technical problems of existing large language model prompt word sensitivity evaluation methods, such as coarse granularity, inability to reveal the micro-mechanisms of sensitivity generation from the model's internal reasoning logic, and the failure of training optimization objectives to directly constrain the consistency of internal inference. The evaluation method includes acquiring input samples and at least two semantically equivalent but formally different prompt word templates; embedding the input samples into each prompt word template to generate a first prompt word and a second prompt word; constructing masked inputs for each subset of the entire set of input variables using masking operations for each of the two prompt words; and feeding these masked inputs into the language model to obtain scalar outputs. This invention enables fine-grained quantitative evaluation and causal analysis of prompt word sensitivity at the level of the model's internal inference units, and actively suppresses the generation of sensitivity during the training phase.

The invention relates to the technical field of biology, in particular to a pharmaceutical composition capable of overcoming drug resistance of lenvatinib and application of the pharmaceutical composition. The pharmaceutical composition comprises an active ingredient targeting a KDM4A-AS1 / ZDHHC3 / WNK1 regulation axis; the active component is at least one of a KDM4A-AS1 targeting inhibitor, a ZDHHC3 targeting inhibitor or a palmitoylation inhibitor of WNK1 at a Cys411 site, and a pharmaceutically acceptable carrier of the active component. The KDM4A-AS1 / ZDHHC3 / WNK1 axis is used for driving the drug resistance of hepatocellular carcinoma (HCC) to lenvatinib by inhibiting pyroptosis. Therefore, each constituent part of the shaft represents a promising treatment target, and a feasible strategy can be provided for restoring the sensitivity of a patient with advanced hepatocellular carcinoma to lenvatinib by inhibiting each treatment target; the compound has a wide prospect in preparation of drugs for treating hepatocellular carcinoma or overcoming drug resistance of hepatocellular carcinoma to lenvatinib.

The application considers factors such as inherent amplitude-phase errors of the single machines and cables, influences of temperature changes on the amplitudes and phases, amplitude-phase weighting values required for the receiving beam, and the like, and ensures that the amplitudes and phases of the receiving channel are accurately controllable.

This utility model relates to the field of atomizing spray gun technology, specifically to an atomizing oil spray gun. It includes: a spray gun body with a piston chamber and a vent hole connected to the piston chamber; a nozzle assembly mounted on one end of the spray gun body, including an oil outlet; a piston rod with the piston chamber opening away from the nozzle assembly; and an end cap mounted on the spray gun body at the opening of the piston chamber. An adjustment knob is threaded onto the end cap, comprising a knob body and a limiting rod. The limiting rod is located on the knob body, which is located outside the end cap. The end of the limiting rod extends into the piston chamber and faces the piston rod to limit its travel. A vent hole communicating with the piston chamber is provided on the end cap. A rotating cavity opening towards the end cap is provided on the knob body, rotatably fitted onto the end cap. The outer opening of the vent hole is located within the rotating cavity.

The invention belongs to the technical field of magnetic resonance, and particularly relates to a temporal-mandibular joint dynamic magnetic resonance radio frequency coil capable of adapting to different head types, which comprises a magnetic resonance machine body, a fixed coil and a movable coil, the multiple fixed coils are arranged on the outer side of an inner cavity of the magnetic resonance machine body in a surrounding mode. The multiple movable coils are arranged in an inner cavity of the magnetic resonance machine body in a surrounding mode and located on the inner rings of the multiple fixed coils. Each movable coil is positioned between two adjacent fixed coils; the plurality of movable coils can move towards the center of the magnetic resonance machine body through a pushing mechanism; the movable coil can be tightly attached to temporomandibular joints of different head types through dynamic adjustment, the signal sensitivity and the image signal-to-noise ratio are effectively improved, and fine structures such as a joint disc are displayed more clearly. The problem that the imaging quality is unstable due to the difference of the head shape and the face contour of the patient is solved, and the consistency and the accuracy of diagnosis are guaranteed.
