Abstract: A lens unit, a lens for a low-beam illumination module, a low-beam illumination module and a vehicle. The lens unit includes a rear surface and a front surface; the lens unit has a focal line, and the focal line is a straight line perpendicular to a light emitting direction of the lens unit; the rear surface and the front surface are adapted to project light rays passing through the focal line into parallel light rays, and the front surface is a free-form curved surface. The lens unit has the optical characteristics of a cylindrical lens, and is able to cause parallel incident light to be focused into a line instead of a focal point upon passing through the lens unit.

Abstract: An efficient anti-bacterial hydroxy acid ester oligomer of the present invention has a general structural formula (I). Starting from the design of molecular structure, the present invention rationally designs the end group and chain length structure of the substance of formula (I), and controls its clogP value, so that the substance of formula (I) of the present invention reaches an appropriate size, which maximizes the ability of the substance of formula (I) to penetrate into the bacteria and destroy the bacterial cell membrane, thereby achieving high anti-bacterial efficiency. By precisely designing the molecular structure, the present invention regulates the hydrophilicity and hydrophobicity of the hydroxy acid ester oligomer to obtain a bio-based anti-bacterial agent with controllable water solubility.

Abstract: This disclosure relates to the fields of applied meteorology, in particular to a visualization analysis method of the tropical cyclone forecast verification index data, which comprises the following steps: acquiring tropical cyclone data; obtaining a track forecast verification index and an intensity forecast verification index of the tropical cyclone with the tropical cyclone data; obtaining a visible view of the tropical cyclone track forecast error and a visible view of the tropical cyclone intensity forecast error according to the track forecast verification index and the intensity forecast verification index, and in combination with the geographic information of the tropical cyclone; obtaining a first error and a second error according to the track forecast verification index, and obtaining a joint distribution map of the first error and the second error by using the first error and the second error; obtaining a composite box-shaped histogram through the intensity forecast verification index.

Abstract: Method, system, and computer-readable medium for scheduling blocking tasks are disclosed. A method includes: executing each of a plurality of task functions in a respective coroutine; detecting a first blocking event for a first task function of the plurality of task functions during execution of the first task function; in response to detecting the first blocking event: setting a respective blocking state of the first task function to a pause state; pausing execution of the first task function; and placing the first task function among a group of paused task functions; and after pausing the execution of the first task function: identifying a second task function among the group of paused task functions for which a respective blocking state has been updated to a running state; removing the second task function from the group of paused task functions; and resuming execution of the second task function.
