This study characterized the mechanism by which bovine serum albumin (BSA) reduces the K(m) for phenytoin (PHY) hydroxylation and the implications of the "albumin effect" for in vitro-in vivo extrapolation of kinetic data for CYP2C9 substrates. BSA and essentially fatty acid-free human serum albumin (HSA-FAF) reduced the K(m) values for PHY hydroxylation (based on unbound substrate concentratio...

The aim of this paper is to integrate security and privacy in mmWave communications. MmWave communication mechanism access three major key components secure (SC) operations. proposed design for facilitates the detection primary signal physical (PHY) layer find spectrum throughput user (PU) secondary (SU). SC PU with maximum being recorded at 0.7934 while SU 0.7679. So, we will a solving problem...

Biocompatible photo-driven producers of singlet oxygen can inhibit the growth drug-resistant bacteria and tumors. In order to develop targeting generator for tumor bacterial treatment, a metal porphyrin liposome (Phy–Mn–Ls) was prepared by coordination reaction self-assembly compounds with polymer (HS–PEG–chol). The production 1O2, binding bovine serum protein (BSA) lipase, toxicity MCF-7 breas...

The use of wireless transmission networks in various environments has become widespread. One the main challenges is that highly vulnerable to eavesdropping attacks. In this paper, an amplify-and-forward cooperative relaying system with relay selection considered improve physical layer (PHY) security presence multiple eavesdroppers, under two cases, namely, perfect channel state information (CSI...

IEEE 802.11n standard has introduced the new schemes in MAC and HT-PHY layers to improve network throughput. The new schemes in MAC layer are A-MSDU, A-MPDU and Block ACK. In the HT-PHY layer there are MIMO transmission using up to 4 spatial streams, 40 MHz bandwidth channel and 400 ns guard interval. In this paper, we proposed an analytical model that can be used to estimates the throughput of...

Thanks to its simplicity and cost efficiency, wireless local area network (WLAN) enjoys unique advantages in providing high-speed and low-cost wireless services in hot spots and indoor environments. Traditional WLAN medium-access-control (MAC) protocols assume that only one station can transmit at a time: simultaneous transmissions of more than one station causes the destruction of all packets ...

Abstract — Space-Time Block Codes (STBC) represent a recent, exciting development in the field of physical layer (PHY) data transmission. By employing more than one antenna at the transmitter, and by properly coding data across the transmit antennas, STBC-equipped PHYs promise increased data rates with minimal decoding complexity at the receiver. This article presents a comprehensive study of h...
