A Matching Optimization Method of Distribution Power Internet of Things Based on Network Looseness
IEEE Access, 2021 Power line carrier communication (PLC) is one of the important technologies to construct and realize ubiquitous power Internet of Things, while the degree of network matching severely affects the communication quality of the network.

Molecular Oncology, EarlyView.The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Design and optimization of grounded coplanar waveguide and chip cascade structure [PDF]
Journal of Hebei University of Science and TechnologyIn order to solve the problem of decreasing transmission efficiency due to impedance abrupt change during the cascade between transmission line and chip, a matching band-line method for X~Ka band was proposed based on the ground coplanar waveguide and ...

Active metamaterials: sign of refraction index and gain-assisted dispersion management
, 2007 We derive an approach to define the causal direction of the wavevector of modes in optical metamaterials, which in turn, determines signs of refractive index and impedance as a function of {\it real and imaginary} parts of dielectric permittivity and ...

Measurements of a Quantum Dot with an Impedance-Matching On-Chip LC Resonator at GHz Frequencies [PDF]
, 2017 We report the realization of a bonded-bridge on-chip superconducting coil and its use in impedance-matching a highly ohmic quantum dot (QD) to a $\rm{3~GHz}$ measurement setup. The coil, modeled as a lumped-element $LC$ resonator, is more compact and has
