Circuits
The circuit is a type of publication, where you can organize and define connections between multiple publications. In a circuit, you can add a materials publication that was described above or another circuit in a node. These nodes can be connected with directed edges which represent the suggested order of examining the publications.

Reputation
The reputation system in the platform is based on the quantity and quality of the publications a user publishes. It reflects on the activity of the user and how others rate their publications and comments.It is directly proportional to the number of publications, comments made and stars a user has received. If another user saves or indicates that they use your publication, this will be reflected in an increase of your reputation.
