Simultaneous Transmit and Receive with Shared-Aperture Arrays
2020 International Applied Computational Electromagnetics Society Symposium (ACES), 2020 An approach based on shared aperture antenna array is researched for simultaneous transmit and receive (STAR) applications. The proposed configuration is a 10×10 antenna array of circularly-polarized (CP) elements with 50 elements, somewhat sparsely distributed, dedicated for Tx while the remaining elements dedicated for Rx.

Aperture-Level Simultaneous Transmit and Receive With Digital Phased Arrays
IEEE Transactions on Signal Processing, 2020 While purely digital phased arrays were once discarded as simultaneous transmit and receive (STAR) capable platforms, this notion has recently been reconsidered. Previous work demonstrated that adaptive digital beamforming and digital self-interference cancellation (SIC) can enable transmitting and receiving subapertures in an array to operate ...

Transmit Beamforming Design Based on Multi-Receiver Power Suppression for STAR Digital Array
SensorsThe simultaneous transmit and receive (STAR) array system provides higher radiation gain and data rate compared to traditional radio system. Because of the various mutual couplings between each pair of transmit and receive elements, it is a great ...

Beam-shape loss for multiple-beam digital array radars
The Journal of Engineering, 2019 This study considers beam-shape loss (BSL) for pencil-beam digital array radars (DARs), when multiple simultaneous receive beams are formed to cover the volume illuminated by each transmit beam.

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.

The Simultaneous Transmit And Receive (STAR) Message Protocol
Supercomputing Frontiers and Innovations, 2017 The STAR protocol is introduced, which solves three problems with MPI, a well known secur- ity problem, and three exascale communication problems. Optical implementations are developed compatible with 100 Gbit/sec Ethernet. Automatic fault resilience mechanisms are discussed, which improve HPC quality of service, and meet the exascale reliability and ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Airborne polarimetric Doppler weather radar: trade-offs between various engineering specifications [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2018 NCAR EOL is investigating potential configurations for the next-generation airborne phased array radar (APAR) that is capable of retrieving dynamic and microphysical characteristics of clouds and precipitation. The APAR will operate at C band.
