In this unit, students will learn about 2D arrays, a data structure that stores objects in a grid or table-like format. You will practice creating, accessing, manipulating, and traversing 2D arrays ...

Aquaporin-0 (AQP0) tetramers form square arrays in lens membranes through a yet unknown mechanism, but lens membranes are enriched in sphingomyelin and cholesterol. Here, we determined electron ...

Abstract: We present a novel augmented reality (AR) display system utilizing a holographic optical element (HOE)-based approach, featuring seamless switching between three-dimensional (3D) and ...

Abstract: A 2-D scanning phased array with large element spacing using pattern reconfigurable stacked patch antenna at Ka-band is presented. The pattern reconfigurable stacked patch antenna is ...

The largest two-dimensional crystal of extremely cold, charged atoms ever created could be used to study poorly understood quantum materials, as well as for building quantum computers. Some crystals ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
