Percolating hierarchical defect structures drive phase

Sep 01, · As stated above, the atomic positions in the Ctype structure can be uniquely related to the fluorite atomic positions (see §3.1.1 and Table S1). As a consequence, r j can be rewritten as r j = r F j + δ r j , where r F j is the equilibrium position of ions in fluorite, while δ r j is the displacement of the same site in the Ctype

How To Use A Thresh To Reduce Background Noise In

Getting a clear signal with reduced noise is an essential component to good data. Adding a thresh when acquiring flow cytometry data is one way to do that. It reduces the number of events by setting a bar that a signal pulse must clear before it is counted as an event. Depending on the importance of the data, the downstream applications for the data (or sorted cells) will
