BACKGROUND Subthalamic nucleus (STN) hyperactivity is a pathophysiological phenomenon of Parkinson's disease (PD). Inhibition of this hyperactivity by chronic deep brain stimulation (DBS) can possibly reset the aberrant function of the cortico-striato-thalamal circuit and improve the parkinsonian symptoms. DBS was introduced as a safe and alternative way of(More)
The wideband code division multiple access (WCDMA) system with high-speed downlink packet access (HSDPA) is an important next-generation wireless system. By adopting adaptive modulation, efficient scheduling, and hybrid automatic repeat request technologies, it can support data rates of up to 10 Mb/s in the mobile cellular environment. Among these(More)
The growing demand of high speed multi-class data transmissions poses new challenges on wireless networks. The major objectives of the next generation wireless networks include: (1) achieving high data throughput in the fast varying wireless channel; (2) transmitting multi-class data by service multiplexing; and (3) controlling the delay for delay sensitive(More)
We experimentally measured the phase-matching spectral phases of aperiodic quasi-phase matched gratings for the first time (to the best of our knowledge) by nonlinear spectral interferometry. The retrieved information is useful in determining the temporal shape of the nonlinearly converted ultrafast signal and reconstructing the slowly-varying domain period(More)
Public housing is the largest housing submarket in Singapore. There is also an active resale public housing market, where public housing dwellers are allowed to trade their houses after a time-bar of five years from the date of their purchase. This segment of resale HDB market is liken the private housing submarkets, where housing prices are more likely to(More)
