Abstract: Disclosed in the present application is a method for fitting spontaneous emission noise of a lidar system or an optical fiber sensing system. The method includes: providing a trigger collection signal by a signal source; triggering, based on the trigger collection signal, a co-located transceiver module and a distributed transceiver module to perform synchronous detection on a detection target; receiving co-located data and distributed data returned by the detection target; subtracting local noise from the co-located data and the distributed data, respectively; selecting a linear interval to normalize the co-located data; performing subtraction operation on the normalized co-located data and the distributed data to obtain spontaneous emission noise; and fitting the spontaneous emission noise by a function.

Abstract: A device stand may include a base having a support portion and a connector portion. An upper surface of the connector portion may include at least one coupling mechanism that is configured to engage with a corresponding feature of a keyboard housing to secure the base with the keyboard housing. The device stand may include a first support member coupled with the support portion. The device stand may include a second support member coupled with the support portion and laterally spaced apart from the first support member to form a channel between the first support member and the second support member. The channel may be sized to receive a computing device.

Abstract: The present invention belongs to the field of medicinal chemistry, and particularly relates to synthesis, a preparation method and the use of an inhibitor containing dual targets SHP2 and CDK4/6, wherein the inhibitor comprises three compounds of general formulas I-III and pharmaceutically acceptable salts, enantiomers, diastereomers, tautomers, solvates, polymorphs or prodrugs thereof. According to the present invention, a class of brand-new SHP2 and CDK4/6 dual-target inhibitors are prepared by means of a pharmacophore fusion and reasonable drug design method, so that the problems of drug resistance, poor drug effect, etc., of the existing SHP2 inhibitor and CDK4/6 inhibitor are solved; the great significance of the present invention is providing the first SHP2 and CDK4/6 dual-target inhibitor, which provides a basis for solving the problem of drug resistance of kinase and phosphatase in the later period.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media for performing preflight checks of a distributed computing system, are described. In one aspect, a method includes assigning a computing workload to a first subset of hardware accelerator machines each having one or more hardware accelerators. A preflight check on the first subset is performed before performing the computing workload to verify the functionality of each machine in the first subset. For each hardware accelerator machine of the first subset, a program code package is installed, including a task action based at least in part on characteristics of the computing workload. The task action including a sequence of operations is performed on the hardware accelerator machine to determine whether the task action fails. Whenever the task action fails, the computing workload is re-assigned to a second subset of hardware accelerator machines different from the first subset.

Abstract: The present application discloses a method and a device for displaying panoramic videos. The method includes: loading a panoramic video from a server through an Html5 video tag in a play page; mapping the panoramic video to the inner surface of a sphere model in a scene as a texture image of the sphere model, wherein the scene is created by an 3D engine, and further includes a camera object disposed inside the sphere model; and displaying a video image of the inner surface of the sphere model shot by the camera object under the current viewing angle in the play page. A third-party plug-in is not needed to be installed while viewing the panoramic video in the web page through a browser, so that the panoramic video can be applied in the internet video more widely, thus providing expedience for an internet user to view the panoramic video.
