Abstract: Embodiments described herein provide a system for three-dimensional (3D) object detection. The system includes an input interface configured to obtain 3D point data describing spatial information of a plurality of points, and a memory storing a neural network based 3D object detection model having an encoder and a decoder. The system also includes processors to perform operations including: encoding, by the encoder, a first set of coordinates into a first set of point features and a set of object features; sampling a second set of point features from the first set of point features; generating, by attention layers at the decoder, a set of attention weights by applying cross-attention over at least the set of object features and the second set of point feature, and generate, by the decoder, a predicted bounding box among the plurality of points based on at least in part on the set of attention weights.

Abstract: A method for managing document revisions. The method includes receiving a request to access a parent file stored on a server, where the parent file is associated with one or more child files; determining whether a first option is enabled that is associated with selecting a latest version or revision of a child file, where a revision includes one or more versions; determining whether a second option is enabled, where the second option is associated with selecting a released version or revision of a child file; and, for each child file, providing access to a version or revision of the child file based on whether the first option is enabled and whether the second option is enabled.

Abstract: A fluid injection apparatus and associated method for supplying a pressurized fluid to a permeable portion of a tree. A fluid injection apparatus comprising a receptacle engageable with the tree forms a chamber around the permeable portion of the tree. A reservoir supplies fluid to a pump which selectively transfers the fluid from the reservoir to the chamber, pressurizing the fluid in the chamber. A tree stand comprising a tree clamp and supporting legs can comprise the fluid injection apparatus. The apparatus enables the method of supplying a pressurized fluid to the permeable portion of a tree comprising: providing a fluid-retaining chamber around a permeable portion of the tree; providing a reservoir containing a supply of the fluid; and selectively pumping the fluid from the reservoir to pressurize the chamber.
