The extensive surviving corpus of the ancient scholar Plutarch of Chaeronea (ca. 45-120 CE) also contains several texts which, according to current scholarly opinion, did not originate with him and are therefore attributed to an anonymous author Pseudo-Plutarch. These include, in particular, the work Placita Philosophorum (Quotations and Opinions of the Ancient Philosophers), which is extremely important for the history of ancient philosophy. Little is known about the identity of that anonymous author and its relation to other authors from the same period. This paper presents a BERT language model for Ancient Greek. The model discovers previously unknown statistical properties relevant to these literary, philosophical, and historical problems and can shed new light on this authorship question. In particular, the Placita Philosophorum, together with one of the other Pseudo-Plutarch texts, shows similarities with the texts written by authors from an Alexandrian context (2nd/3rd century CE).

昼夜节律是哺乳动物（例如睡眠，代谢，稳态，情绪变化等）各种重要生理和行为过程的中心。已经表明，这种节奏来自位于上核（SCN）中的神经元网络的自维持的生物分子振荡。在正常情况下，由于视网膜的信号，该网络仍然同步到昼夜周期。这些神经元振荡与外部光信号的未对准会破坏众多生理功能，并对健康和福祉造成持久的损失。在这项工作中，我们研究了现代的计算神经科学模型，以确定昼夜节律对不同频率和占空比外部光信号的限制。我们采用无基质方法来定位各种驾驶条件的高维模型的周期性稳态。我们的算法管道可以实现分叉图的数值延续和构建W.R.T.强制参数。我们在计算中探讨了昼夜节律网络中异质性的影响，以及矫正治疗性干预措施（例如药物分子长期的）的效果。最后，我们采用无监督的学习来构建数据驱动的嵌入空间来表示神经元异质性。
