Abstract: The disclosure discloses a low-loss transmission line structure, which belongs to the field of radio frequency transmission lines and includes at least two metal layers stacked in a vertical manner. A dielectric layer is filled between the metal layers. The metal layers include a signal transmission strip in a middle portion. Ground strips are provided on both sides of the signal transmission strip. Through holes are evenly distributed on the dielectric layer, and the signal transmission strips on each of the metal layers are connected through the through holes to form a signal transmission line. The ground strips on each metal layer are connected through the through holes.

Abstract: A high-side driver method for a laser of a Lidar, including: transforming a first input signal into a second input signal between a first voltage value and a second voltage value, by a level translation module; stepping down a first voltage signal according to a first voltage difference to obtain a second voltage signal, by a low-dropout linear regulator; generating a first control signal, by the first pre-driver module; generating a pulse current for driving the laser, by the first power switching transistor.

Abstract: Provided are an intraoperative planning adjustment method, apparatus and device for TKA (Total Knee Arthroplasty) and a computer-readable medium. The method comprises: importing preoperative planning data; performing image registration on preoperative planning images and the surface contour of a knee joint of a surgical object; acquiring the dynamic spacing force line data of the knee joint at a continuous flexion-extension angle; visually displaying the dynamic spacing force line data graph; and adjusting prosthesis planning according to the visual display of the dynamic spacing force line data. By calculating information such as the joint gap and the force line angle of the lower limb at the continuous flexion-extension angle in the operation, the method provides a comprehensive adjustment information source in the operation for a surgeon, and therefore a better operation planning is obtained.

Abstract: The present application provides a total knee arthroplasty robot auxiliary system, a control method, electronic device and a computer readable medium.

Abstract: The invention relates generally to methods of screening for drugs which bind to and/or regulate cellular proteins involved in drug resistance, particularly resistance of tumor cells to chemotherapeutic agents.
