Stochastic Models and Descriptive Statistics for Phylogenetic Trees, from Yule to Today

In 1924 Yule observed that distributions of number of species per genus were typically long-tailed, and proposed a stochastic model to fit these data. Modern taxonomists often prefer to represent relationships between species via phylogenetic trees; the counterpart to Yule’s observation is that actual reconstructed trees look surprisingly unbalanced. The imbalance can readily be seen via a scat...

The normal healthy fetus receives a constant influx of glucose from the mother. This constant influx provides for basal fetal metabolism. The normal fetoplacental glucose utilization rate is 5 to 6 mg/kg/min. After 27 weeks gestation, this glucose influx also provides for convertion into glycogen, which is deposited mainly in the liver. The fetal glucose levels are maintained by transport of ma...
