A composite forming method and device combining electric pulse creep aging with laser peening are provided. The method includes modeling a ribbed integral panel, simulating a creep forming process of the panel, and determining and marking localized difficult-to-deform areas. The panel is then pre-bent into shape, and the localized difficult-to-deform areas are performed a laser shock strengthening treatment. Electric pulse heating treatment is performed on the panel and creep aging forming is started. Whether an accuracy of the component surface meets a target accuracy is determined by comparing the scanned component surface with a target surface. For areas that do not meet the target accuracy, a secondary laser shock strengthening treatment is applied. The accuracy of the component surface is repeatedly determined until it meets the target accuracy. The present application improves a forming efficiency of complex curvature components.

The present invention relates to the technical field of dental image display. It provides a dental image display method and a dental handpiece. First, a 3D tooth image is formed via scanning. Then, at each moving position, a light-sensing component and a first camera respectively collect the first and second partial dental arch images, and a positional association is established between them. When the dental handpiece operates in the oral cavity, a second camera captures a real-time image. Based on this image, the partial dental arch image targeted by the handpiece's working component is determined and displayed on the handpiece's screen. This invention overcomes the prior-art problem of blocked sight during operation, facilitating the doctor's work and enabling the handpiece to function as an oral mirror.

An optimized method for expansion and large-scale production of regulatory T cells (Tregs) includes the following steps: preparing a cord blood-derived Treg-containing suspension; transferring the cord blood-derived Treg-containing suspension into a sterile tube matching with a magnetic pole, and magnetically sorting CD4+CD25+CD127− Tregs out; adding an expansion culture medium to Tregs carrying magnetic beads, conducting a primary culture for 1 d to 2 d, and conducting a subculture once every 1 d to 3 d, where a total culture time is 40 d to 50 d.

In addition, an expansion effect will not be gradually deteriorated. Thus, the method greatly increases the expansion generation number and the quantity of Tregs, and can meet the needs of clinical patients.

Introduced are a method, a software apparatus, an electronic device, and a storage medium for simulating inerter using finite element analysis. The method involves: acquiring structural parameters of an inerter; simulating the mechanical properties of racks on rigid rods and flywheels within the inerter using the structural parameters and a finite element platform; formulating constraint equations and transformation formula to simulate translational-rotational conversion and inertia amplification mechanism of the inerter; integrating the force and constraint information to achieve the finite element simulation of the inerter. The finite element simulation method for the inerter addresses the challenge of lacking “inerter units” and the inability to simulate inertia components in general finite element software platforms. It also overcomes the technical bottleneck of real-time dynamic coupling simulation between inerter and complex engineering structures. This may effectively promote the design, optimization, and application of inerter in the vibration control of large-scale engineering structures.

The invention provides a wind power forecasting method and system based on an asymmetric Laplace distribution. It utilizes the asymmetric Laplace distribution to model the uncertainty of the power forecasts. First, the maximum information coefficient (MIC) is used to characterize the linear and nonlinear relationship between the target and historical power data to select reasonable and optimal inputs. Then, to avoid the information loss, a multi-scale feature fusion module is proposed which combines the features obtained from different convolutional layers of a convolutional neural network (CNN), thereby further enhancing the feature extraction ability of the traditional CNN. Finally, a BiLSTM is used to extract temporal information and forecast the parameters of asymmetric Laplace distribution.

The present disclosure relates to a high-selectivity hydrophilic electrode for electrochemically extracting lithium and a preparation method thereof. The preparation method includes the step of carrying out surface coating modification on an electrode active material by using polydopamine. The interception of impurity ions is achieved by utilizing the advantages, which polydopamine has, of preferentially accumulating and transporting lithium ions, thereby improving the selectivity of the electrode active material on lithium.

When contacting mercury in a gas phase and/or a liquid phase, the modified natural sulfide ore material can convert the mercury into a stable compound to realize the immobilization and removal of the mercury, which has advantages such as large mercury adsorption capacity, high adsorption rate, wide application temperature range, low cost, abundant raw material reserves, simple operation, and environmentally-friendly mercury removal products without secondary pollution and shows promising industrial application prospects.

An adjustable deforming composite structure based on a hydrogen-induced expansion effect and a preparation method therefor are provided. The hydrogen-induced expansion effect means metals absorb hydrogen under a hydrogen-containing atmosphere and at a temperature to produce a volume expansion effect. Reactions between the metals and hydrogen are reversible reactions. When a hydrogen partial pressure is reduced or the temperature is increased, the hydrogen in the metals is removed, and the metals are restored to an original shape. Under a stimulation of external hydrogen and heat, a composite of a hydrogen-absorbing metal and other non-hydrogen-absorbing materials undergo an adjustable deformation according to a design, and a material undergoes reversible shape changes. The preparation method is applied to composite materials for a 4D printing and is used for an intelligent shape adjustment at a medium to high temperature.
