Abstract: An example particle therapy system includes a gantry having a beamline structure configured to direct a particle beam that is monoenergetic from an output of a particle accelerator towards an irradiation target, where the beamline structure includes magnetic bending elements to bend the particle beam along a length of the beamline structure; and an energy degrader downstream of the beamline structure relative to the particle accelerator, where the energy degrader is configured and controllable to change an energy of the particle beam prior to at least part of the particle beam reaching the irradiation target.

Abstract: The present disclosure relates to systems, methods, and devices for sending and receiving payments using an integrated payment and messaging system. In particular, the integrated payment and messaging system allows users to send and receive electronic payments as well as exchange messages. For example, one or more implementations involve facilitating message exchanges and payment transactions using push notifications via separate message and payment queues. To illustrate, one or more implementations involve pushing status updates to a payment transaction using a payment queue specific to a user. Additionally, one or more implementations involve associating payment transactions with messages within a messaging thread for providing updates to each user in the messaging thread.

Abstract: The present disclosure relates to systems, methods, and devices for enabling peer-to-peer loan transactions. In particular, the message system allows users of a social networking system to initiate peer-to-peer loan transactions. For example, one or more implementations involve recommending potential lenders likely to loan money to a user requesting a peer-to-peer loan transaction. One or more embodiments of the message system provide a loan request message to a potential lender. Additionally, one or more embodiments receive an acceptance of the requested loan transaction and initiate the loan transaction by transferring a loan amount from a payment credential of the potential lender to the user.
