Abstract: Phase-shifter-aided spatial multiplexing (PSSM) has recently emerged as an efficient multiple-input multiple-output (MIMO) technique with reduced radio frequency (RF) chains. In this ...

Abstract: In nonlinear contrast-enhanced ultrasound (CEUS) imaging, nanobubbles (NBs) offer a promising alternative for enhanced visualization of microvascular structures and molecular imaging. This ...

I'm trying to limit the bandwidth of signals in my dataset with the following configuration: seed = 1234 signal_bandwidth_min = 100_000 signal_bandwidth_max = 500_000 sample_rate = 80_000_000 ...

Numbers stations demonstrate decades of robust RF communication design, offering insights into propagation optimization and one-way transmission security. Explore AM/CW modulation, ionospheric physics ...

The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

The circuit was designed to operate a voice transmitter over the AM medium wave band under a limited power output. Amplitude Modulation – a method or technique of emphasizing and transmitting data or ...
