Abstract: Some examples of the disclosure are directed to systems and methods for presenting content in a three-dimensional environment by one or more electronic devices in a multi-user communication session. In some examples, a first electronic device and a second electronic device are communicatively linked in a multi-user communication session, wherein the first electronic device and the second electronic device are configured to display a three-dimensional environment, respectively. In some examples, the first electronic device and the second electronic device are grouped in a first spatial group within the multi-user communication session. In some examples, if the second electronic device determines that the first electronic device changes states (and/or vice versa), the user of the first electronic device and the user of the second electronic device are no longer grouped into the same spatial group within the multi-user communication session.

Abstract: Some examples of the disclosure are directed to systems and methods for facilitating display of content and avatars in a multi-communication session including a first electronic device and a second electronic device. In some examples, the first electronic device presents a computer-generated environment including an avatar corresponding to a user of the second electronic device and a first object, wherein the computer-generated environment is presented based on a first set of display parameters satisfying a first set of criteria, including a spatial parameter for the user of the second electronic device, a spatial parameter for the first object, and a display mode parameter for the first object. In response to detecting a change in one or more of the first set of display parameters, the first electronic device updates presentation of the computer-generated environment in accordance with the one or more changes of the first set of display parameters.

Abstract: A sorting nozzle having two tapered zones with elliptical cross-sections is able to orient and sort a large fraction of asymmetrical or "flattened" cells. This nozzle has particular application for sorting viable male (Y) and female (X) sperm populations in a cell sorter.
