Shuttle flight experiment preliminary proposal: Demonstration of welding applications in space [PDF]
In June 1991 work was initiated at MSFC on an end-effector for 'Robotic Assembly of Welded Truss Structures in Space'. The case for welded joint assembly on orbit was discussed in the 1991 SFFP Final Report 'D'.

XOR‐Logic Phase Coding Programmable Metasurface for Low Power‐Consumption Systems
Advanced Science, EarlyView.By leveraging XOR logic, the biasing‐network complexity of 2D programmable metasurfaces is reduced from m×n to m+n through efficient row‐column control. This enables versatile functions including beam deflection and beamforming, facilitating applications in wireless communications and beyond.
