Abstract: The present disclosure relates to systems and methods for providing personalized retrievals of items. The systems and methods create a user-specific morph operator for a user that captures learned user preferences for the user. The systems and methods use the user-specific morph operator to transform a generic embedding for a query into a personalized embedding for the query. The systems and method use the personalized embedding to retrieve items based on the user preferences to present in response to the query.

Abstract: This application discloses a long-focus lens, a camera module, and an electronic device. The long-focus lens includes a first lens assembly, a second lens assembly, and a third lens assembly that are arranged from an object side to an image side. The first lens assembly and the third lens assembly are fixed lens assemblies, and the second lens assembly is a focusing lens assembly. In a focusing process in which the long-focus lens is switched from a long shot to a close-up, the second lens assembly moves toward the object side along an optical axis, a combined focal length of the first lens assembly and the second lens assembly decreases, and a combined focal length of the second lens assembly and the third lens assembly decreases. The foregoing long-focus lens has a strong focusing capability and high imaging quality.

Abstract: A method for manufacturing an aluminum alloy vehicle body includes the following steps: vehicle body part molding, including: profile stretch-bending and machining; vehicle body frame assembly welding, including: performing assembly welding on a lower vehicle body, left and right side panels, and front and rear roof crossbeams; outer panel manufacturing, including: manufacturing an outer panel by injection molding; and whole vehicle assembling, including: assembling interior trim parts and the outer panel to a vehicle body frame, and assembling chassis parts to the vehicle body frame. The vehicle body parts and the vehicle body frame are made of an aluminum alloy material, and the outer panel is made of a non-metallic composite material.

Abstract: A monolithic laser cavity device includes an input mirror coating, a birefringent crystal quarter waveplate such as sapphire, a birefringent crystal gain medium such as neodymium-doped vanadate, a Type-II second-harmonic-generation crystal such as potassium titanyl phosphate, and an output mirror coating. The optical axes of the Type-II second-harmonic-generation crystal and birefringent crystal gain medium are aligned with each other and aligned 45° relative to the optical axis of the birefringent crystal quarter waveplate.

Abstract: The current invention provides an optical disruptor having a laser system, a rangefinder, where the rangefinder provides a real-time distance to a target, control electronics; and dynamically-controlled output optics. The dynamically-controlled output optics are actuated by the control electronics to provide a divergence in real-time of an output of the laser system, where the real-time divergence is according to the real-time distance to the target.
