Abstract: We previously implemented an inexpensive imaging system that combines a single real camera with a mirror array located along a paraboloid. It allows us to robustly acquire dynamic light ...

WASHINGTON — Array Labs, a Silicon Valley startup developing radar-based Earth observation satellites, announced Jan. 5 it raised $20 million in a Series A round as it pushes to bring lower-cost ...

In the high desert of New Mexico, a few hours southwest of Albuquerque, is the Very Large Array, or VLA for short. It’s the largest telescope in the world, using 27 individual antenna to listen to the ...

In May, a research team from MIT announced a new programming language, Finch. It’s designed to support both flexible control flow and diverse data structures. “Finch facilitates a programming model ...

There is a phenomenon in the Python programming language that affects the efficiency of data representation and memory. I call it the "invisible line." This invisible line might seem innocuous at ...

I frequently encounter situations where I need to load data from a Pandas DataFrame into NumPy arrays, perform computations, and then update the DataFrame. Typically, I have two approaches: Loading ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

Abstract: This letter presents a wideband dual-polarized antenna array decoupling structure based on a polarization convert reflective surface (PCRS). The PCRS unit consists of a rectangular metal ...
