Abstract: The present disclosure relates to a NiTi alloy surface cutting process and a roughness adjustment method. Aiming at defects of difficult machining and unsatisfactory machining performance of Ni—Ti alloys, the present disclosure provides a surface cutting process of a difficult-to-machine nickel-titanium alloy, in which firstly, the nickel-titanium alloy is transformed from a two-phase state to a single-phase state using its transformation characteristic, and electrochemical nickel removal treatment is carried out on a surface of the alloy in the single-phase state so as to obtain a porous surface layer, and then a surface material with the porous surface layer is cut. The method provided by the present disclosure can effectively reduce machining difficulty of alloy materials, and can also obtain alloy workpieces with adjustable roughness, which is of great significance for NiTi alloy machining.

Abstract: A method for preparing a microstructure on the surface of glass by titanium oxide nanoparticle-assisted infrared nanosecond laser, including the following steps: (1) dropwise applying a titanium oxide nanoparticle hydrogel onto the surface of a glass sample; (2) pressing another piece of glass on the surface of the hydrogel, so the hydrogel is evenly distributed between the two pieces of glass, and allowing the two pieces of glass to stand horizontally for a period of time to air-dry the hydrogel; (3) separating the two pieces of glass to obtain a glass with a uniform titanium oxide nanoparticle coating; (4) forming a microstructure using an infrared nanosecond laser with a wavelength of 1064 nm; and (5) performing after-treatment, including ultrasonically cleaning the sample with acetone, absolute ethanol and deionized water respectively for 10 min to remove titanium oxide nanoparticles attached to the surface, to obtain a glass sample with the microstructure.

Abstract: Systems and methods for establishing call connection in response to user action, the method including receiving a first user action from a user associated with making a call connection, wherein the first user action comprises any of copying at least part of a phone number, pasting at least part of the phone number, or inputting at least part of the phone number. The method also includes determining one or more call recipients based on the first user action. The method also includes establishing one or more silent call connections based on the determined one or more call recipients, wherein each of the one or more silent call connections comprises a call connection with a predetermined parameter so that there are no incoming call indicators on one or more devices associated with the one or more call recipients.

Abstract: A group of anti-BCM single domain antibodies, as well as genes of the single domain antibodies in the group, a vector containing the single domain antibodies in the group, a chimeric antigen receptor, and a T cell modified by a chimeric antigen receptor, and detection and treatment application of the single domain antibodies in the group. The anti-BCMA single domain antibodies have high activity, high stability, high specificity, and high binding capability.

Abstract: A chimeric antigen receptor (CAR) may be include: a BCMA binding domain, a transmembrane domain, a co-stimulatory domain, and an intracellular signaling domain, wherein the BCMA binding domain includes heavy chain complementarity determining regions HCDR1-3, and the amino acid sequences of the HCDR1-3 are successively as shown in SEQ ID NO: 1-3.
