The magnetic assembly, the conductive case and the sound control plate form a magnetic loop to form a magnetic system, and after the coil is electrified, an alternating magnetic field is generated, the alternating magnetic field intensity of the magnetic system is changed.

Abstract: Certain aspects of the present disclosure provide techniques for securely accessing a wallet on a blockchain. An example method generally includes receiving a request to access a wallet on a blockchain. The request generally includes an authorization code associated with the wallet and user credentials associated with an owner of the wallet. A first portion of a private key is decrypted based on the authorization code and a salt associated with the user credentials, and a second portion of the private key is decrypted based on credentials associated with an application through which the wallet is accessed. Access to the wallet is granted based on the decrypted first portion and the decrypted second portion of the private key.

Abstract: Certain aspects of the present disclosure provide techniques for securely accessing a wallet maintained by a centralized platform on a blockchain. An example method generally includes receiving a request to access one or more wallets on a blockchain. Generally, the request includes an authorization code associated with a controlling party associated with the one or more wallets and user credentials associated with the controlling party. A first portion of a private key is decrypted based on the authorization code and a salt associated with the user credentials associated with the controlling party, and a second portion of the private key is decrypted based on credentials associated with an application through which the wallet is accessed. Access to the one or more wallets is granted based on the decrypted first portion and the decrypted second portion of the private key.

Abstract: Among the various aspects of the present disclosure is the provision of compositions and methods of treating or preventing various headache disorders or neuropathic pain by increasing the number of Treg cells in a subject. In particular, low dose IL-2, rapamycin, statin or Treg cell administration are shown to be useful in treating or preventing headache or neuropathic pain.

Abstract: Provided is a method for presenting resources. The method includes: playing, in response to a launch operation on an application, a first media resource of a target activity in an initialization page of the application, wherein an activity interaction control is presented in a resource screen of the first media resource; displaying, in response to an interaction operation on the activity interaction control, the activity interaction control performing an action corresponding to the interaction operation; and presenting a second media resource of the target activity.

Abstract: A three-axial ribbon cutter and an implementation method thereof are disclosed, which relates to a technical field of ribbon cutting. The cutter includes a base, a traversing cutter set, a ribbon guiding mechanism, a first guide rail, a second guide rail, a cutting cylinder, a lifting cylinder, a traversing cylinder and a ribbon. An mounting block is provided on the base, the mounting block is connected with the traversing cutter set, the ribbon guiding mechanism, the first guide rail, the cutting cylinder, the lifting cylinder and the traversing cylinder; cutters of the traversing cutter set and the ribbon guiding mechanism are provided in multiple sets; the traversing cutter set includes special-shaped cutters which are connected to the cutting cylinder and the traversing cylinder, edges of the special-shaped cutters extend by a certain volume, and the traversing cutter set and the lower cutter are both connected to the lifting cylinder.

Abstract: A method for an analysis of drug molecular dynamics results based on root-mean-square deviation multiple features is disclosed. The method includes the following steps: (i) analyzing and extracting features of a molecular dynamics RMSD image; (ii) performing a calculation of a binding free energy and an energy decomposition by using a molecular mechanics/Poisson-Boltzmann surface area method; and (iii) SVM classification training. By using RMSD image and molecular mechanics/Poisson-Boltzmann surface area method, the drug molecular dynamics are more efficient and accurate.

Abstract: A beverage pod is assembled to allow the upper extension of the filter to separate from the upper rim of the container upon an application of force upon the extension. An energy director may be provided between the extension and the rim such that when a linear vertical high-frequency energy is applied to the energy director, the energy director may melt and releasably join the extension to the rim. At least one of the extension and/or the rim may have an energy director protruding therefrom. Separating the extension from the rim may form a gap between the extension and the rim to allow the beverage formed within the pod to drain therethrough.

Abstract: Disclosed is an industrial vehicle, which includes a handle (32), a main vehicle frame (2), and a drive wheel assembly (33), a vertical column (1) being mounted on the main vehicle frame (2), the vertical column (1) comprising an upper top plate (11) and a back plate (13) connected to the upper top plate (11); the industrial vehicle also includes a controller (52), a pump station (53), and a jacking device (51) that abuts against the upper top plate (11); in the horizontal direction, the jacking device (51) is farther from the handle (32) than the drive wheel assembly (33). The foregoing industrial vehicle has high stability and stable lifting, optimizes the positional relationships of each component of the vehicle, and has a shorter vehicle body, such that a smaller turning radius is thus obtained.
