Three experiments explore how American (N = 102) and Egyptian (N = 73) preschoolers’ inferences about expertise are affected by an expert’s gender and occupation. Children viewed a nurse and a car mechanic in a gender stereotypical (female nurse, male mechanic) or counterstereotypical (female mechanic, male nurse) presentation and indicated who would know more about profession-related informati...

This study documents age trends, interrelations, and correlates of intellectual abilities in old and very old age (70-103 years) from the Berlin Aging Study (N = 516). Fourteen tests were used to assess 5 abilities: reasoning, memory, and perceptual speed from the mechanic (broad fluid) domain and knowledge and fluency from the pragmatic (broad crystallized) domain. Intellectual abilities had n...

Tunnel effect is a possible mechanism to explain the apparent large electric conductivity and nonlinear electric behavior of graphene-reinforced nanocomposites with polymer matrix. In this work, a numerical modeling framework is proposed to evaluate the effective electric conductivity in polymer composites reinforced with graphene sheets, taking into account the electrical tunneling effect, whi...

Results He had Type II A aortic dissection with intimal tear at proximal region of the right coronary ostium. Mechanic aortic valve was normal function. Ascending aorta was replaced by using 26 mm Dacron tube graft between annulus of previous mechanic aortic valve and distal ascending aort by using hypothermic circulatory arrest and antegrade selective cerebral perfusion. An 8 mm dacron tube gr...

The hysteretic behavior of many-particle systems with non-convex free energy can be modeled by nonlocal Fokker-Planck equations that involve two small parameters and are driven by a timedependent constraint. In this paper we consider the fast reaction regime related to Kramers-type phase transitions and prove that the dynamics in the small-parameter limit can be described by a rate-independent ...

In this paper, we develop two efficient numerical methods for a multiscale kinetic equation in the context of crowd dynamics with emotional contagion [A. Bertozzi, J. Rosado, M. Short and L. Wang, Contagion shocks in one dimension, J. Stat. Phys. 158 (2014) 647–664]. In the continuum limit, the mesoscopic kinetic equation produces a natural Eulerian limit with nonlocal interactions. However, su...

A virtual finite element framework is presented to provide the transition from a high fidelity model more computationally efficient continuum for simulating fibre-dominated damage behavior in composite laminates subjected tensile loadings. The method LS-DYNA based on use of cohesive interface elements simulate both intra-laminar matrix cracks and delamination. Applied IM7/8552 carbon fibre rein...

Quasi-continuum (QC) methods are computational techniques, which reduce the complexity of atomistic simulations in a static setting while keeping information on smallscale structures and effects. The main idea is to couple atomistic and continuum models and thus to obtain quite detailed but still not too expensive numerical simulations. We aim at a mathematically rigorous verification of QC met...
