Abstract: Aspects of photonic band gap resonators for magnetic resonance are described. In one example, an apparatus includes a 1D structure having a plurality of layers. A respective thickness of the individual layers is one-quarter of a respective wavelength of a target magnetic resonance frequency within the individual layers of the plurality of layers, or a multiple thereof. A first layer has a first dielectric constant, and a second layer that is adjacent to the first layer has a second dielectric constant. A defect includes a sample. The defect has a thickness that is approximately up to one-half of a wavelength of the target magnetic resonance frequency within the defect.

Abstract: Disclosed are various embodiments for providing a spectrally efficient communication network using clustered devices and virtualized resources in a multi-input multi-output (MIMO) environment. A plurality of remote radio heads (RRHs) can be connected to a central base band unit (BBU) pool of a software-defined network (SDN) associated with the communication network. A procedure can be performed to yield a design for software-defined massive MIMO subject to a plurality of constraints. The design provides a plurality of clusters comprising the RRHs and an association of user devices to the clusters. Examples of initiating implementation of the design by the SDN are provided.

Abstract: In one aspect, the disclosure relates to a process for dehydrogenating a first dehydrogenation reactant into its unsaturated counterparts. The disclosed process comprises introducing a dehydrogenation reactant to a metal oxide catalyst having dehydrogenation activity, and dehydrogenating the dehydrogenation reactant to provide its unsaturated counterpart and hydrogen; selectively combusting the hydrogen released during dehydrogenation using a lattice oxygen from the metal oxide catalyst, resulting in a reduced metal oxide catalyst and steam; re-oxidizing the reduced metal oxide catalyst by introducing a gaseous oxidant to the reduced metal oxide catalyst; and optionally re-using the re-oxidized metal oxide catalyst for catalytic conversion and combustion. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
