N1 - Funding Information:
To address the specific deficits in mental health expertise in rural and remote locations, the UDRH Mental Health Academic (MHA) project was established in 2007. Additional funding was provided by the Australian Government (Department of Health) to support the appointment of MHAs. Each of the 11 UDRHs appointed an MHA. The aim of the MHA role was to improve the mental health status of rural and remote Australians through key activities set by the Department of Health (Table 1).

N2 - We investigate the operation of an all-optical wavelength converter/regenerator device, constructed from a nonlinear module and an interferometer. Nonlinear devices based upon cross-gain and cross-phase modulation will invert an input signal, and the interferometer's operating point can be chosen to re-invert or not re-invert the signal exiting the nonlinear device. It is proven that superior performance is obtained when the interferometer does not re-invert the signal. This result concurs with experimental reports.
