One of the critical issues for the proliferation of Internet of Things (IoT) is the collection and computational analysis of wireless data from huge networks of smart sensors being implemented in applications that include smart transportation and cities. Recently, the technique of over-the-air computation (AirComp) has been proposed as an integrated approach for collection and processing of data from sensor networks transmitting Big-data simultaneously. Notably, although this method is efficient, it requires that all signals from nodes arrive simultaneously at the sink, aligned in signal magnitude so as to enable an unbiased estimation. However, for nodes far away from the sink with low channel gains, it is not possible to avoid misalignment in signal magnitude.

Insulators, by definition, do not conduct electrical current (in theory), and have a high electrical resistivity. Still, physicists distinguish between various types of insulators, differing in how the insulating states come about. The most common insulators are materials in which electrons cannot flow freely; too much energy would be required to ‘unbind’ them. Other types include Anderson insulators, in which electrons are ‘stuck’ because of quantum interference effects, and topological insulators, which are actually conducting at their surface. But one type of insulator, the so-called excitonic insulator, is particularly special — because it has never been unambiguously observed.

Reinforcement Learning (RL) is an effective way of designing model-free linear quadratic regulators (LQRs) for linear time-invariant networks with unknown state-space models. RL has wide ranging applications including industrial automation, self-driving automobiles, power grid systems, and even forecasting stock prices for financial markets.
