Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.

Abstract: The embodiment of the present disclosure discloses a method, an electronic device, and a storage medium for a ship route optimization. The method for the ship route optimization considers a dynamic feature of a multi-functional emergency rescue ship and an interference effect caused by an airflow, uses a movement model with kinematics non-holonomic constraints, such as a ship total cost assessment function to simulate the movement of the ship, and based on a sparrow search algorithm, learns how to apply the algorithm to a route plan of the emergency rescue ship. The method can improve the ship route optimization algorithm, improve an accuracy and practical applicability of a calculated plan. The method can effectively and accurately locate obstacles and hidden reefs, and consider effects of an airflow and a non-holonomic constraint effect, so as to make the route planning of the ship more efficient and intelligent.

Abstract: Provided is a fusion protein of human serum albumin or a wild type thereof and human interleukin-2 or a mutation thereof, said fusion protein has a significantly extended in vivo half-life relative to recombinant interleukin-2, can be used alone for treating a tumor, and improves anti-tumor efficacy of an anti-PD-1 antibody or an anti PD-L1-antibody.

Abstract: A method and system of import and export trading is provided. The system and method includes a selection module, an import duty confirmation module, a database, and a displaying module. The selection module is configured for choosing basic information of commodity from lists of property choices provided by a website and submitting the choice to a server. The import duty confirmation module is configured for confirming HS code and duty rate corresponding to the commodity according to the choice. The database is configured for storing information of commodities, HS codes and rate of import duties. The displaying module is configured for displaying commodities provided by sellers to buyers for choosing. The sellers and buyers are in different countries or regions, when a buyer chooses one commodity, the server will provide corresponding import duty to the buyer according to the quantity of commodities and the duty rate.

Abstract: An alarm system (10) includes a plan management module (100), a production management module (200) and an alarm management module (300). The plan management module receives a customer order and sets planned delivery data according to the customer order. The production management module downloads production data. The alarm management module determines whether the production data conform to the planned delivery data and generates an alarm if the production data do not conform to the planned delivery data. A related method for production schedule control is also provided.
