On using the Gameboy Advance as a controller for inverted pendulums [PDF]

2013 International Conference on Robotics, Biomimetics, Intelligent Computational Systems, 2013
This paper describes the usage of a Gameboy Advance (GBA) for non-gaming applications in control systems. The GBA is extended with the XPort and the XPort Robot Controller developed by Charmed Labs. Typical control problems include balancing an inverted pendulum about its unstable vertical equilibrium point. This paper also explores the capabilities of

Advances in recurrence and malignant transformation of sinonasal inverted papillomas

Oncology Letters, 2017
Sinonasal inverted papilloma (SIP) is a benign tumor of the nasal cavity and sinus. SIP is characterized by aggressive malignant transformation and a high rate of recurrence. Inadequate removal of the tumor during surgery is one of the most significant contributors to SIP recurrence. A growing body of evidence suggests that molecular alteration in SIP,
