3 Mechanisms for Magnesium Deficiency
Over 45% of the US population is deficient in magnesium due to: 1. Decreased consumption of green chlorophyll-containing vegetables, 2. Decreased absorption, 3. Increased excretion. Some magnesium supplements have better magnesium bioavailability than others. ▶︎ See part I on Magnesium

Hierarchical Clustering 3: single-link vs. complete-link
[http://bit.ly/s-link] Agglomerative clustering needs a mechanism for measuring the distance between two clusters, and we have many different ways of measuring such a distance. We explain the similarities and differences between single-link, complete-link, average-link, centroid method and

Point defects in ceramics and polymers
Point defects in ceramics and polymers are more complex than those in metals. The reason for this is that ceramics constitute anion and cation. Since these ions are charged and electroneutrality must be maintained, then defects must come in pairs, rather than single defects. There are many
