Abstract: Analytical expression of transmission for the orbital angular momentum (OAM) communication using loop antenna arrays and paraboloids is derived to achieve a communication distance of 100 m.

Thomas Mulligan explains the complex nature of time travel by analyzing the inconsistent causal loop (the grandfather paradox) and the consistent causal loop (the bootstrap paradox). New supermarket ...

Human-in-the-loop (HITL) has emerged as the default answer to concerns about AI trust, safety and governance. The logic is that when AI systems make decisions that affect people, a human should be ...
