![]() The way we live is shaped by the social structures around us, like our families, our community, and our religious groups It says that social structures guide our lives, which are mostly predictable ways to act in groups.Sociology’s structural-functional approach takes the notion that society is a multi-party system that needs to be stabilised and supported in order for it to function properly. ![]() Let’s look into this a little more and look at a few examples. Social functions, social structure, manifest functions, and latent functions are some of the most important concepts in functionalism. Robert Merton and Herbert Spencer were two of the most important thinkers who came up with this point of view. People who study society are called sociologists, and they come up with different frameworks or theories to help them understand what we see every day in the world around us.

The highest occupied molecular orbital of the transition state is visualized and the distribution of the orbital densities of the transition states is described for a few prototype S N2 reactions.ĬoeffNet: predicting activation barriers through a chemically-interpretable, equivariant and physically constrained graph neural network We test CoeffNet on a dataset of S N2 reactions as a proof-of-concept and show that the activation barriers are predicted with a mean absolute error of less than 0.025 eV. Model outputs are either activation barriers or coefficients of the chosen molecular orbital of the transition state the latter quantity allows us to interpret the results of the neural network through chemical intuition. We show that using coefficients as features offer several advantages, such as chemical interpretability and physical constraints on the network's behaviour and numerical range. In this work, we introduce CoeffNet, an equivariant graph neural network that predicts activation barriers using coefficients of any frontier molecular orbital (such as the highest occupied molecular orbital) of reactant and product complexes as graph node features. However, computing these energy barriers by identifying transition states with electronic structure methods ( e.g., density functional theory) can be time-consuming and computationally expensive. Activation barriers of elementary reactions are essential to predict molecular reaction mechanisms and kinetics.
