Abstract: The disclosure describes embodiments of systems, methods, and non-transitory computer readable storage media that utilize a machine learning model and a credit value model to generate user interface elements that present credit values and credit value conditions in real time for user accounts. For instance, the disclosed systems can generate an activity score using an activity machine learning model with internal user activity data of a user account. Then, utilizing a credit value model with the activity score and a user activity condition, the disclosed systems can determine a dynamic credit value range for the user account. Indeed, the disclosed systems can display user interface elements with selectable credit values from the dynamic credit value range. Additionally, the disclosed systems can utilize the credit value model to determine and display one or more dynamic credit value conditions for a selected credit value received from the selectable credit values.

Abstract: An apparatus for irradiating a biological substance with a substantially uniform quantity of radiation energy comprises a radiation-generating device for producing radiation energy, a support structure for receiving the biological substance, and a motorized mechanism for reciprocating the radiation-generating device along a given path whereby the biological substance receives radiation energy from the radiation-generating device at each passage of the radiation-generating device. A series of sensors lie into a given plane and are subjected to radiation energy from the radiation-generating device upon each passage of that radiation-generating device for sensing and measuring the quantity of radiation energy by surface unit passing through the given plane and reaching the biological substance. Finally the radiation-generating device and the motorized mechanism are de-energized when the measured quantity of radiation energy by surface unit has reached a predetermined value.
