The U-Pb and Pb-Pb isotopic dating of zircons provided the ages of 447-462Ma representing the ages of peak granulitic metamorphism. The U-Pb dating of detrital zircons from aluminum-rich gneisses yielded older upper intercept ages which reflect the times of older materials derived from sourse rocks of the gneiss protoliths.

岩石中变质锆石的U-Pb及Pb-Pb同位素测定获得447-462Ma的年龄值，代表其麻粒岩相的变质作用时代，富铝片麻岩中含继承组分的锆石还获得较老的上交点年龄，它可能代表其沉积岩原岩源区的年龄。

More neurospheres were derived from the hippocampi of mice that had exhibited prolonged seizures than from those in which seizures occurred in short bursts.

His Song of the Dark Forest artfully evokes a folk idiom through its poetic metre (a modified kol'tsovskiy stikh ), word repetition, and spare harmony which avoids the leading note. The seven songs composed between 1867 and 1871 conclude with Borodin's second Heine setting, Iz slyoz moikh ('From my Tears'), which is noteworthy for still further effects derived from 2nds.
