Deployment of distributed renewable energy resources is increasing rapidly, which is leading to growing concerns over the impact of distributed power electronics energy converters on grid stability. In general, power electronic coupled systems do not provide frequency or voltage support through feedback compensation. This is leading to changes in utility interconnection requirements for distrib...

There remains considerable uncertainty about the underlying causes and functional significance of cortical oscillation and synchronization. We examined the temporal structure and synchronization of spikes in cell assemblies (groups of 4-6 cells with similar orientation preference). Recordings were made with a 5x5 microelectrode array in supragranular layers of Area 17 of cats paralyzed and anes...

In this work, we use the gridded precipitation dataset (with a resolution of 0.5◦ × 0.5◦) of the eastern part of inland river basin of Inner Mongolian Plateau from 1961–2015 as the basis and adopt the methods of climatic diagnosis (e.g., the Modified Mann-Kendall method, principal component analysis, and correlation analysis) to analyze the spatial and temporal variations of six extreme precipi...
