Presenilin-1 (PS1) is a multifunctional protein involved in many cellular functions including the processing of type 1 membrane proteins such as β-amyloid precursor protein (APP) and Notch 1 receptor. PS1 acts as the catalytic subunit of the γ-secretase complex, and participates in Notch 1 processing to release Notch intracellular domain (NICD) in the(More)
—We analyze the throughout achievable in transmission over block-fading channels when the instantaneous channel state information (CSI) is not available at the transmitter. Assuming operation with incremental redundancy hybrid ARQ (HARQ), we propose to adapt the transmissions rates using the outdated CSI, i.e., the one experienced by the receiver in the(More)
BACKGROUND Cost of delivering reproductive health services to low-income populations will always require total or partial subsidization by the government and/or development partners. Broadly termed "Demand-Side Financing" or "Output-Based Aid", includes a range of interventions that channel government or donor subsidies to the service user rather than the(More)
The original idea of mobile IP (MIP) is to provide mobile users the ability to access the Internet anywhere, with an identical IP address. With rapid changes in both technology and the communication environment, wide bandwidth and low cost wireless LAN (WLAN) have emerged as a competitive choice not only for wireless high speed Internet access but also for(More)
High Peak-to-Average Power Ratio (PAPR) is one of the main drawbacks that may limit practical applications of Orthogonal Frequency Division Multiplexing (OFDM) System. Based on the well known Selective Mapping (SLM) method of PAPR reduction, in this paper, we propose a new phase sequence generation technique from Condex matrix that can achieve better PAPR(More)
The Mobile IP (MIP) enables a mobile user to access the Internet anywhere with an identical IP address. However, in order to support mobility with quality of service (QoS), MIP can be inefficient for both data and time sensitive services such as voice-over-IP (VoIP). Broadband accessed network server IP mobility architecture facilitates WLAN IP mobility(More)
The integration of wireless local area networks (WLANs) and the high speed wide area network (WAN) using 'always on' broadband access that could provide an efficient and cost effective inter-WLAN mobility management requires the current WLAN internetworking protocol enhanced. The Inter Access Point Protocol (IAPP) defines methods for access point(More)
