Abstract: The present invention provides a model for high-throughput screening of endocrine disruptors and a method for screening the same. In the present invention, primary structural alerts, secondary structural alerts and tertiary structural alerts of compounds are extracted according to a nuclear receptor, and then the primary structural alerts, the secondary structural alerts and the tertiary structural alerts form a nuclear receptor high-throughput screening model; hierarchical structural alert matching is carried out on target compounds through the nuclear receptor high-throughput screening model, and ligand-receptor binding mode analysis and semi-quantitative prediction of binding activity and disrupting activity are performed.

Abstract: An implantation system for a cochlear implant microelectrode with remote motion center control includes: an electrode implantation device including at least one pair of forceps, and a distal end part of the forceps is used as a remote motion center; a six-degree-of-freedom motion mechanism; an input unit, configured to input a surgical trajectory; and a control unit, configured to calculate, a displacement of the forceps in a first body coordinate system, an offset compensation of each motion execution unit at the front end at a corresponding degree of freedom in the first body coordinate system, and an offset compensation of each motion execution unit at the rear end at a corresponding degree of freedom in a second body coordinate system, and drive, based on the corresponding offset compensation and a preset motion priority, the forceps and the corresponding motion execution unit to act.

Abstract: A robot for pond desilting is provided, which includes a frame, a lead screw sliding table, and a suction pipe. An end of the frame is provided with a pressure-resistant cabin. A lead screw base is disposed on the lead screw sliding table. A rotary lead screw is disposed on the lead screw sliding table. The lead screw base is disposed on the rotary lead screw. Waterproof motors are disposed above the lead screw base, a pump body is disposed in the frame, and the suction pipe is disposed at an end of the pump body. When the robot is placed at the bottom of the pond, the motor inside the pressure-resistant cabin drives the power wheels to rotate, the power wheels drive the tracks to rotate around the power wheels, bearing wheels, and tension wheels, thereby driving the frame to move.

Abstract: Present invention provides a method for inferring the type of a road segment, comprising the steps of: collecting historical driving trajectory data of a plurality of vehicles for a target road segment, performing a statistic on the historical driving trajectory data, and obtaining statistical features of the target road segment; extracting topological features of the target road segment from topological structure data of the road network; merging the statistical features with the topological features of the target road segment, and obtaining an arrogated feature vector of the target road segment; building a logistic regression model according to the arrogated feature vector, and obtaining a first inferred type of the target road segment. The present embodiment considers both the driving trajectory data of a plurality of vehicles and the topological structure data of the road network, the accuracy of the present invention is high, and the inferred result is accurate.
