mm-Wave Waveguide Traveling-Wave Power Combiner Design Using an Equivalent Circuit Model
IEEE Access, 2019 The waveguide traveling-wave power combiner (WTWPC) falls into the category of asymmetrical non-isolated power combiners, and, therefore, the active load modulation occurring within the combiner was investigated.

Working Memory Load Modulates Neuronal Coupling [PDF]
Cerebral Cortex, 2017 Abstract There is a severe limitation in the number of items that can be held in working memory. However, the neurophysiological limits remain unknown. We asked whether the capacity limit might be explained by differences in neuronal coupling.

Heat removal efficiency of stratum ventilation for air-side modulation [PDF]
, 2019 Stratum ventilation has significant thermal non-uniformity between the occupied and upper zones. Although the non-uniformity benefits indoor air quality and energy efficiency, it increases complexities and difficulties in the air-side modulation. In this
