Abstract: Signum-coded synthetic aperture radar (SC-SAR), also known as the 1-bit SAR, significantly reduces the system complexity and data processing throughput by retaining only the sign information ...

ABSTRACT: This paper develops the second stage of quantization in the NUVO scalar-conformal framework, extending the arc-closure geometry of Quantization I to include loop structures and circulation.

Escalating from last month’s internal warnings of rough vibes, OpenAI CEO Sam Altman has declared a company-wide “Code Red” to salvage his flagship product. As a result, the “Pulse” personal assistant ...

Astronomers are puzzled, and that’s putting it mildly. A strange pattern of pulses, repeating like clockwork, has been detected from 3I/ATLAS, an interstellar object cruising through our Solar System.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Polar codes significantly improve coding performance for 5G. At the same time, they reduce the complexity of design and ensure service quality. Basic research is key to industry development.

Abstract: Images include information about human body which is used for different purposes such as medical, security and other plans. Compression of images is used in some applications such as ...
