Recent VLSI hash function designs allow incorporating features such as more complex input expansion schedules, more rounds and bigger states into these functions. As a result, these hash functions are slower and bulkier when compared with previous ones such as MD4, MD5, SHA-1, RIPEMD, etc. An architecture and VLSI implementation of a new hash function called RadioGatún, that achieves high-speed...

IPv4 addresses have been depleted in February 2011, when the IANA allocated the remaining last five /8s IPv4 address blocks to the RIRs. IPv6 has been developed by the IETF as a solution to the exhaustion of IPv4 addresses. In this paper, we present some models to evaluate the performance of IPv4 and IPv6 in Ethernet networks, the most widely-installed local area network technology. Our models ...

Next generation wireless network is envisioned as a convergence of different wireless access technologies providing the user enhanced connection any where any time to improve the systems resource utilization. It is likely that WLAN/HIPERLAN will become an important complementary technology to cellular networks and typically used to provide hotspot coverage where there is a high density of users...

The myelin basic protein (MBP) gene encodes two families of proteins, the classic MBP constituents of myelin and the golli-MBPs, the function of which is less well understood. In this study, targeted ablation of the golli-MBPs, but not the classic MBPs, resulted in a distinct phenotype unlike that of knock-outs (KOs) of the classic MBPs or other myelin proteins. Although the golli KO animals di...

Abstract MD5 is an authentication algorithm, which has been proposed as the default authentication option in IPv6. When enabled, the MD5 algorithm operates over the entire data packet, including header. This RFC addre...

BACKGROUND DNA methylation is an epigenetic modification that plays a crucial role in a variety of biological processes. Methylated DNA is specifically bound by Methyl-CpG Binding Proteins (MBPs). Three different types of MBPs have been identified so far: the Methyl-CpG Binding Domain (MBD) family proteins, three BTB/POZ-Zn-finger proteins, and UHRF1. Most of the known MBPs have been identified...

Shiverer (shi) is an autosomal recessive mutation in mice that results in hypomyelination in the central nervous system (CNS) but normal myelination in the peripheral nervous system (PNS). Myelin basic proteins (MBPs) are virtually absent in both PNS and CNS. It is not known whether the cellular target in the PNS is the myelin-forming Schwann cell or another cell type which secondarily affects ...

In this paper, we propose a method to improve the performance of initial channel estimation (CE) for the multiband-OFDM (MB-OFDM) UWB. The performance of the initial CE can be generally improved as increasing the number of the used preamble symbols. The MB-OFDM specification presents two CE symbols per band in preamble format. The performance of CE estimation with two CE symbols may be satisfie...
