We present an efficient explicitly correlated pair natural orbital local second-order Møller-Plesset perturbation theory (PNO-LMP2-F12) method. The method is an extension of our previously reported PNO-LMP2 approach [ Werner et al. J. Chem. Theory Comput. 2015 , 11 , 484 ]. Near linear scaling with the size of molecule is achieved by using domain(More)
To investigate the evolution of market dynamics in different stages of historical development, we analyze commodity prices from two distinct periods —ancient Babylon, and medieval and early modern England. We find that the first-digit distributions of both Babylon and England commodity prices follow Benford’s law, indicating that the data represent(More)

A well-parallelized local singles and doubles coupled-cluster (LCCSD) method using pair natural virtual orbitals (PNOs) is presented. The PNOs are constructed using large domains of projected atomic orbitals (PAOs) and orbital specific virtual orbitals (OSVs). We introduce a hierarchy of close, weak, and distant pairs, based on pair energies evaluated by(More)
We present an efficient explicitly correlated pair natural orbital local coupled cluster (PNO-LCCSD-F12) method. The method is an extension of our previously reported PNO-LCCSD approach ( Schwilk et al., J. Chem. Theory Comput. 2017 , 13 , 3650 - 3675 ). Near linear scaling with the molecular size is achieved by using pair, domain, and projection(More)
Dynamic electrocardiogram (ECG) monitoring is significantly superior to conventional static ECG inspection in application scope and clinical study. With the increasing number of guardianship and healthcare category, health surveillance platform will produce a large number of monitoring data. The traditional monitoring technology has been unable to(More)
Human language, as a typical complex system, its organization and evolution is an attractive topic for both physical and cultural researchers. In this paper, we present the first exhaustive analysis of the text organization of human speech. Two important results are that: (i) the construction and organization of spoken language can be characterized as(More)
