In this paper, the performance improvement in multi-carrier direct-sequence code-division multiple-access (MC-CDMA) power line communication (PLC) systems using partial parallel interference cancellation (PPIC) multiuser detectors is investigated. The high data rate demanded in the multimedia PLC systems can be offered by the MC-CDMA systems. However, the(More)
Alzheimer's disease (AD) is an age-related neurodegenerative disease, affecting over 20 million people worldwide. Until recently, two major hypotheses were proposed regarding the molecular mechanism of pathogenesis: the cholinergic hypothesis and the amyloid cascade hypothesis. At present, acetylcholinesterase inhibitors(More)
Curcumin is commonly applied as food coloring and seasoning but recent research show that curcumin is able to enhance the activation of Fas receptor to the cancer cell apoptosis through extrinsic pathway. Oral cancer results from the particular habit of chewing betel nuts that Taiwanese have. The additive in betel nuts (such as lime) is the main reason that(More)
In this paper, the performance of parallel interference cancellation (PIC) multi-user detectors in orthogonal frequency division multiple access (OFDMA) mobile communication systems is investigated. In multi-user systems, the multi-user interference (MUI) degraded the system performance, especially in near-far effect environments. An adaptive weight partial(More)
