The result obtained showed that the mean values of all the elements were higher than the recommended FAO/WHO and International Atomic Energy Agency (IAEA) 407 standards, except for K, Ca, Sr and As, which were lower than the IAEA 407. Generally, the concentration of elements in muscle and...

Hence, in order to reduce the overlap between the two classes of generated molecules, we only take the top 20% fragments with the smallest attributions less than 0 as the negative fragments, and only the top 20% fragments with the largest attributions higher than 0 as the positive fragments....
Astumian, R. D. Kinetic asymmetry allows macromolecular catalysts to drive an information ratchet.Nat. Commun.10, 3837 (2019).This paper describes the kinetics of molecular motors through a framework that has come to be known as trajectory thermodynamics, useful for the understanding of ratchets....

The results of this paper rely on the following definition. A many-body atomic state is any state which is adiabatically connected to a trivial many-body atomic limit which is (1) non-degenerate, (2) spatially decoupled, and (3) endowed with a many-body gap. This limit allows for ...
In order to alleviate the above challenges, this paper proposes a machine learning (ML) model based on neural networks. The model can assist both PSCs design and analysis of their potential mechanism, demonstrating enhanced and comprehensive auxiliary capabilities. To make the model have higher ...
Further, EDTA and DTPA have low selectivity for cations with a similar valence; however, they bind M3+ with a higher affinity than M2+. The acyclic chelator HBED-CC is unique in its use of two lipophilic phenolic groups for [68Ga]Ga3+ coordination141. The [68Ga]Ga-HBED-CC complex ...
Also, variable temperature 1H-NMR studies showed that while at low temperatures (−50 °C) the wheel is localized on the O-benzyl function (of the central phenylene), at higher temperatures (+50 °C) the wheel is free to rapidly move along the axle. This temperature-dependent ...
