  • Publication number: 20240141537
    Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.

  • Patent number: 11956114
    Abstract: A device management method includes a first network device sending a first remote procedure call (RPC) request message to a second network device, where the first RPC request message includes information about a third yet another next generation (YANG) module that is identifiable to the first network device. After the second network device switches to the third YANG module, the first network device establishes a control session between the first network device and the second network device based on the third YANG module. When the network device supports switching between YANG modules of different standards, the second network device is notified, by using an RPC, to switch to a YANG module supported by the first network device.

  • Patent number: 11952368
    Abstract: Provided are a fibroblast activation protein inhibitor (FAPI) dimer compound, an FAPI dimer-based positron emission tomography (PET) imaging agent for tumor diagnosis, and a preparation method and use thereof. An amphiphilic polyethylene glycol (PEG) chain and a dimerized structure of FAPI in the FAPI dimer compound with a structure shown in formula I can improve the in vivo kinetic properties of the compound and prolong a residence time of the compound in a tumor, thereby improving the uptake and imaging effects in the tumor. The accurate tumor diagnosis can be achieved by labeling the FAPI dimer compound with a diagnostic nuclide (68Ga), which has promising application prospects in PET imaging for diagnosis and in the preparation of a therapeutic nuclide (such as 177Lu or 90Y)-labeled drug for treating a FAP-?-expressing tumor.

  • Patent number: 11906309
    Abstract: An approach is provided for providing a map matcher tolerant to wrong map features. The approach involves, for instance, finding a segment of a probe trajectory containing a plurality of low-speed probe points. The approach also involves forming a line between a first and a last probe point of the segment. The approach further involves calculating a distance from each probe point of the segment to the line. The approach further involves splitting the segment based on comparing the distance to a threshold at a turning point of the segment. The approach further involves creating a new probe trajectory based on a plurality of high-speed probe points in the probe trajectory and the turning point. The approach further involves estimating a heading of the turning point of the segment based on the new trajectory, and then performing a feasibility check between two consecutive probe points of the new trajectory.
