The development of emotion recognition from facial expressions and non-linguistic vocalizations during childhood [PDF]

open access: yes, 2014
Sensitivity to facial and vocal emotion is fundamental to children's social competence. Previous research has focused on children's facial emotion recognition, and few studies have investigated non-linguistic vocal emotion processing in childhood.

Complementarity-based nonlinear programming techniques for optimal mixing in gas networks

open access: yesEURO Journal on Computational Optimization, 2019
We consider nonlinear and nonsmooth mixing aspects in gas transport optimization problems. As mixed-integer reformulations of pooling-type mixing models already render small-size instances computationally intractable, we investigate the applicability of ...

New Estimates On Various Critical/Universal Quantities of the 3D Ising Model [PDF]

open access: yes, 1997
We present estimates for the 3D Ising model on the cubic lattice, both regarding interface and bulk properties. We have results for the interface tension, in particular the amplitude sigma0 in the critical law sigma = sigma0*t**mu, and for the universal ...
