Characterisation of millimetre wave multimode radio-over-fibre systems [PDF]

, 2008
Millimetre wave radio-over-fibre links using both singlemode and multimode fibres are demonstrated over a 0-50 GHz bandwidth operating at 1550 nm. Results show that good link gain can be achieved with both single mode and multimode detectors.Millimetre ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Photonic Generation of Ultrawideband (UWB) Pulse With Tunable Notch-Band Behavior

IEEE Photonics Journal, 2012
A photonic approach to generating the ultrawideband (UWB) pulses with tunable band-rejection behavior based on a negative coefficient two-tap microwave photonic filter is proposed and experimentally demonstrated. To avoid the interference between UWB and

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 ...

Optical network architectures for dynamic reconfiguration of full duplex, multiwavelength, radio over fiber [PDF]

, 2006
In recent years there have been rapid advances in the techniques to generate and transport radio signals over optical fiber, but very little has been done to date to develop the concept of a full duplex, multiwavelength, radio-over-fiber network ...

Power-over-Fiber Co-Transmission with Analog Radio-over-Fiber over a Single Standard Single-Mode Fiber

Photonics
To enable mains-free wireless access in confined environments such as tunnels and mines, this paper proposes and experimentally demonstrates a converged power-over-fiber (PoF) and analog radio-over-fiber (A-RoF) system over a single standard single-mode ...
