Adaptive AF/DF Selection With FD/HD Switching in Two-Way Relay Networks

IEEE Access, 2017
The full-duplex (FD) and two-way relay are promising techniques for their high spectrum efficiency. However, the incompletely self-interference cancellation may reduce the performance gain of two-way relay networks, which operates in FD mode.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Physical layer multicasting over 2-hop network using dual amplify and forward relay

, 2010
The inherent multicast nature of the wireless medium can be exploited over two hop networks paves a way for Physical layer multicasting. The system performance gain can be achieved through multicast diversity achieved with dual amplify-and-forward (AF ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Outage probability of unequal block-based OFDM Amplify-and-Forward relay protocol over wideband channels

, 2012
In this paper, we consider a dual-hop multiplerelay network with orthogonal frequency division multiplexing (OFDM) based Amplify-and-Forward (AF) relay protocol over frequency-selective channels. In practice, subcarriers suffered that suffer deep fade in

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Signal-to-Noise Ratio Comparison of Amplify-Forward and Direct Link in Wireless Sensor Networks [PDF]

, 2007
We compare the signal-to-noise ratio performances of an amplify-forward relay link and a direct link in a wireless sensor network. For a slow Rayleigh fading channel, an exact expression for the probability that the SNR of an amplify-forward relay link ...
