Further Findings on the Intergenerational Transmission of Alcohol Consumption
Health Economics, EarlyView.ABSTRACT Using 43,817 parent–child pairs from 23 waves of the HILDA Survey, I study the intergenerational transmission of alcohol use within a rational model of trait transmission. Transmission is predominantly same‐sex: the mother–daughter elasticity is 0.10 and the father–son elasticity is 0.09; there is no father–daughter effect.

T-Spline Surface Toolpath Generation Using Watershed-Based Feature Recognition
Applied Sciences, 2020 The freeform surface is treated as a single machining region for most traditional toolpath generation algorithms. However, due to the complexity of a freeform surface, it is impossible to produce a high-quality surface using one unique machining process.

An efficient data structure for calculation of unstructured T-spline surfaces
Visual Computing for Industry, Biomedicine, and Art, 2019 To overcome the topological constraints of non-uniform rational B-splines, T-splines have been proposed to define the freeform surfaces. The introduction of T-junctions and extraordinary points makes it possible to represent arbitrarily shaped models by ...

Reward processing in children with affective dysregulation
JCPP Advances, EarlyView.Abstract Background Affective dysregulation (AD) in children is characterized by irritability, anger, and frequent intense temper outbursts. Considerable evidence implies altered processing of frustration about missed rewards, but few studies investigated the preceding and thus potentially predictive reward anticipation and initial delivery processing ...

Volumetric Untrimming: Precise decomposition of trimmed trivariates into tensor products
, 2019 3D objects, modeled using Computer Aided Geometric Design tools, are traditionally represented using a boundary representation (B-rep), and typically use spline functions to parameterize these boundary surfaces.

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐
