From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Reconfigurable Intelligent Surface Enabled Spatial Modulation for Visible Light Communications

IEEE Photonics Journal, 2023
An important issue in visible light communications (VLC) is how to boost up the system throughput even when the line-of-sight (LOS) link is blocked by obstacles. In this paper, we propose reconfigurable intelligent surface (RIS) based spatial modulation (

Two High-Performance Schemes of Transmit Antenna Selection for Secure Spatial Modulation [PDF]

IEEE Transactions on Vehicular Technology, 2018
In this paper, a secure spatial modulation system with artificial noise-aided is investigated. To achieve higher secrecy rate (SR) in such a system, two high-performance schemes of transmit antenna selection (TAS), leakage-based and maximum secrecy rate (

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

New Trellis Code Design for Spatial Modulation

, 2011
Spatial modulation (SM) in which multiple antennas are used to convey information besides the conventional M-ary signal constellations is a new multiple-input multiple-output (MIMO) transmission technique which has recently been proposed as an ...

Spatial modulation for generalized MIMO: challenges, opportunities and implementation [PDF]

, 2013
A key challenge of future mobile communication research is to strike an attractive compromise between wireless network's area spectral efficiency and energy efficiency.

Multiple access spatial modulation [PDF]

EURASIP Journal on Wireless Communications and Networking, 2012
In this study, we seek to characterise the behaviour of Spatial modulation (SM) in the multiple access scenario. By only activating a single transmit antenna for any transmission, SM entirely avoids inter-channel interference, requires no synchronisation between the transmit antennas and a single radio frequency chain at the transmitter.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Recursive least-squares adaptive channel estimation for spatial modulation systems

, 2009
In this paper, a recursive least-squares (RLS) adaptive channel estimation scheme is applied for spatial modulation (SM) system over a block fading multiple-input-multiple-output (MIMO) channel.

Codebook-based precoding for generalized spatial modulation with diversity

EURASIP Journal on Wireless Communications and Networking, 2019
This paper investigates codebook-based precoding for spatial modulation (SM) and generalized spatial modulation (GSM) systems. Codebook-based precoding allows the system to dispense with full channel state information at the transmitter (CSIT).
