Abstract: Children who experience anxiety associated with novel situations react physically and emotionally in ways that make it challenging for the child, parents, educators, and providers to proceed with the intended goal of that novel situation. Anxiety in children can be reduced by introducing fun or distracting stimuli that act on specific neural pathways. The stimuli introduced can familiarize a child with the environment in which the procedure will take place and the equipment and people which the child will meet. In the healthcare setting, by using consistent stimuli, and by disrupting anxiety at one or more of a series of stages in which anxiety typically occurs, a reduction in needed anesthesia can be achieved, which is healthier for the child and reduces the costs associated with the medical or dental procedure.

Abstract: Computing devices for automatic placement and arrangement of objects in computer-based 3D environments are disclosed herein. In one embodiment, a computing device is configured to provide, on a display, a user interface containing a work area having a template of a 3D environment and a gallery containing models of two-dimensional (2D) or 3D content items. The computing device can then detect, via the user interface, a user input selecting one of the models from the gallery to be inserted as an object into the template of the 3D environment. In response to detecting the user input, the computing device can render and surface on the display, a graphical representation of the 2D or 3D content item corresponding to the selected model at a location along a circular arc spaced apart from the default viewer position of a viewer of the 3D environment by a preset radial distance.

Abstract: A system for classifying a target image with segments having attributes is provided. The system generates a graph for the target image that includes vertices representing segments of the image and edges representing relationships between the connected vertices. For each vertex, the system generates a subgraph that includes the vertex as a home vertex and neighboring vertices representing segments of the target image within a neighborhood of the segment represented by the home vertex. The system applies an autoencoder to each subgraph to generate latent variables to represent the subgraph. The system applies a machine learning algorithm to a feature vector comprising a universal image representation of the target image that is derived from the generated latent variables of the subgraphs to generate a classification for the target image.

Abstract: An application on a device may interact with a document service that provides access to a document service. The interaction may occur in a variety of contexts, such as a device context (e.g., the document service and the application provided on the same device), a local context (e.g., via a LAN), and a remote context (e.g., over the Internet). It may be advantageous to adapt the interaction to the current context, while also providing a consistent application interface that alleviates the application from context-specific implementations, and also achieving this adaptation in a performant manner. These considerations may be achieved in a balanced manner by providing a set of runtimes, where each runtime mediates the application/document service interaction between the application and the document service in a contextually adapted manner. The device may automatically detect the context of the interaction and select a contextually suitable runtime to service the application.

Further, a bias voltage source is coupled to the supply voltage source and configured to supply a bias voltage to the lens electrode. Electrons striking the lens electrode are thereafter returned to the filament.
