Movable-Antenna Array Enhanced Beamforming: Achieving Full Array Gain With Null Steering [PDF]

open access: yesIEEE Communications Letters, 2023
Conventional beamforming with fixed-position antenna (FPA) arrays has a fundamental trade-off between maximizing the signal power (array gain) over a desired direction and simultaneously minimizing the interference power over undesired directions.

Array programming with NumPy [PDF]

open access: yesNature, 2020
Array programming provides a powerful, compact and expressive syntax for accessing, manipulating and operating on data in vectors, matrices and higher-dimensional arrays. NumPy is the primary array programming library for the Python language.

The NumPy Array: A Structure for Efficient Numerical Computation [PDF]

open access: yesComputing in science & engineering (Print), 2011
In the Python world, NumPy arrays are the standard representation for numerical data and enable efficient implementation of numerical computations in a high-level language. As this effort shows, NumPy performance can be improved through three techniques:

In-flight performance and calibration of the Infrared Array Camera (IRAC) for the Spitzer Space Telescope [PDF]

open access: yesSPIE Astronomical Telescopes + Instrumentation, 2004
The Infrared Array Camera (IRAC) is one of three focal plane instruments on board the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band images at 3.6, 4.5, 5.8, and 8.0 μm in two nearly adjacent fields of view ...

First M87 Event Horizon Telescope Results. II. Array and Instrumentation [PDF]

open access: yes, 2019
The Event Horizon Telescope (EHT) is a very long baseline interferometry (VLBI) array that comprises millimeter- and submillimeter-wavelength telescopes separated by distances comparable to the diameter of the Earth. At a nominal operating wavelength of ~

A mammalian methylation array for profiling methylation levels at conserved sequences

open access: yesNature Communications, 2021
Infinium methylation arrays are not available for the vast majority of non-human mammals. Moreover, even if species-specific arrays were available, probe differences between them would confound cross-species comparisons.

Science with the Cherenkov Telescope Array [PDF]

open access: yes, 2017
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA is extremely broad: from understanding the role of relativistic cosmic ...
