The bi-phase modulation (BPM) for ultra-wide bandwidth (UWB) systems has some advantages over other modulation schemes such as a smoother power spectral density and higher resistance to jitter. In this paper, we estimated the BER performance of the BPM for two different data rates, 10 Mbps and 100 Mbps, in a multipath environment through simulation and compared the results with that for the pul...

Applying a joint code and decoder design methodology, we develop a high-speed (3, k)-regular LDPC code partly parallel decoder architecture, based on which a 9216-bit, rate1/2 (3, 6)-regular LDPC code decoder is implemented on Xilinx FPGA device. When performing maximum 18 iterations for each code block decoding, this partly parallel decoder supports a maximum symbol throughput of 54 Mbps and a...

The distribution of newly synthesized proteolipid protein (PLP, 23 kdaltons) and myelin basic proteins (MBPs, 14-21.5 kdaltons) was determined in microsomal and myelin fractions prepared from the brainstems oi 10-30 d-old rats sacrificed at different times after an intracranial injection of 3~S-methionine. Labeled MBPs were found in the myelin fraction 2 min after the injection, whereas PLP app...

Since its conception by Xerox in the mid-seventies and standardization as IEEE 802.3 in 1983, Ethernet has become the de facto standard for computer communication in the business world. Ethernet networks have evolved from coaxial cable-based systems delivering 3-Mbps performance to systems built from unshielded twisted pair (Cat5 UTP) cables that can deliver high reliability, low cost, and 100-...

The major problem of using light fidelity (Li-Fi) technology is still limited to the line sight (LOS) conditions, which poses a challenge perform bandwidth efficiency support increased bit rates, especially for indoor use. In addition, distance between lamp driver (transmitter) and receiver becomes critical discussion determine characteristics propagation losses. Therefore, this study focuses o...

Morning Surge, Dipping, and Sleep-Time Blood Pressure as Prognostic Markers of Cardiovascular Risk To the Editor: Verdecchia et al recently reported lowest cardiovascular disease (CVD) risk in hypertensive patients of the first quartile of the early morning blood pressure (BP) surge (MBPS) determined by a single before-treatment 24-hour ambulatory BP monitoring (ABPM), defining their results as...

This paper describes a digital forensic tool that uses an FPGA-based embedded software application to identify and track contraband digital files shared using the BitTorrent protocol. The system inspects each packet on a network for a BitTorrent Handshake message, extracts the “info hash” of the file being shared, compares the hash against a list of known contraband files and, in the event of a...

DNA methylation is an epigenetically inherited chemical modification that is associated with transcriptional silencing and is essential for mammalian development. The DNA methylation signal is read out by methyl-CpG binding proteins (MBPs) that specifically bind to methylated DNA. Three structurally divergent families of MBPs have been identified so far: the MBD family, the SRA family and a fam...
