Q‐GEM: Quantum Chemistry Knowledge Fusion Geometry‐Enhanced Molecular Representation for Property Prediction

open access: yesAdvanced Science, EarlyView.
This work introduces E‐GeoGNN, a graph neural network framework that systematically encodes molecular structural information through three hierarchical correlation graphs: atom‐bond graph, bond‐angle graph, and angle‐dihedral graph. By incorporating quantum and geometric dual‐scale self‐supervised pretraining, Q‐GEM is proposed, a novel molecular ...

Relationships of Smiling and Flirtation to Aggression and 2D:4D, a Prenatal Androgen Index

open access: yesEvolutionary Psychology, 2011
Smiling has been reported to be a signal of submission/lower status, or a sign of cooperation. In the present study, use of smiling and flirtation to “make people receptive to my ideas” was conceptualized as mild aggression, since it is mildly ...

Mandelbrot and the Smile

open access: yesCredit and Capital Markets – Kredit und Kapital, 2009
Summary/Zusammenfassung Mandelbrot and the Smile It is a well-documented empirical fact that index option prices systematically differ from Black-Scholes prices. However, previous research provides inconclusive results whether the observed volatility smile could be explained by a discretetime dynamic model of stock returns with skewed, leptokurtic ...

Training Approach-Avoidance of Smiling Faces Affects Emotional Vulnerability in Socially Anxious Individuals

open access: yesFrontiers in Human Neuroscience, 2013
Previous research revealed an automatic behavioral bias in high socially anxious individuals (HSAs): Although their explicit evaluations of smiling faces are positive, they show automatic avoidance of these faces. This is reflected by faster pushing than
