Chemical zoning within mineral grains can be leveraged to determine the maximum length of time the grains could have remained at magmatic temperatures without being compositionally homogenized by element diffusion16. This study constrains the highest temperature portion of the Mg-suite cooling path by ...
15, we show the characteristics of a representative classifier, corresponding to the heat shock factor response element (SR-HSE) task in the Tox21 panel. In a 5-fold cross-validation, active molecules got higher prediction scores than inactive compounds (Supplementary Fig. 15). Moreover, the ...
add(atom1, element) Creates a new atom of the specified element and joins it to atom1 with a single bond. Done done This is an extremely important statement and can be easily overlooked. Repeat: do not forget to put at least a done statement in each transform. After all operations ...
There are 38 isotopes of zinc, ranging in atomic weights from Zn-54 to Zn-83.Just four of these are stable, and those four, plus one naturally radioactive isotope (Zn-70) that has a very long half-life (5×10+14years), make up the element’s existence onEarth. Their proportional ...
indicating that the measured concentrations are well explained by the source contribution estimates. Theχ2value is the weighted sum of squares of the differences between the measured and calculated element concentrations. Ideally, there should be no difference, resulting inχ2of 0. A largeχ2(>4.0...
