The composition and origin of Earth’s earliest continental crust remains enigmatic due to the absence of Hadean (>4 Ga) age rocks. Here we address this question by using machine learning to examine the provenance of the 4.4–3.3 Ga Jack Hills zircons
Compounds having a LogBB ≥ 0.3 can cross the BBB easily and potentially while the value with LogBB < -1 are considered to be poorly distributed through to the BB barrier. All the three compounds evaluated and found that all proposed drugs poorly able to cross the BBB (TTable ...
TheTypeDescriptionProviderclass relies on a parent object of the same type, supplied during construction. This allows classes that derive fromCustomTypeDescriptorto selectively override methods. Instances ofTypeDescriptionProviderare only built upon demand, minimizing the impact of custom type information on...
