Item Childhood Reports of Food Neglect and Impulse Control Problems and Violence in Adulthood(MDPI AG, 2018-06-01) Vaughn, M. G.; Salas-Wright, C. P.; Naeger, S.; Huang, J.; Piquero, Alex R.; 0000 0001 2098 3962 (Piquero, AR); 2088022 (Piquero, AR); Piquero, Alex R.Food insecurity and hunger during childhood are associated with an array of developmental problems in multiple domains, including impulse control problems and violence. Unfortunately, extant research is based primarily on small convenience samples and an epidemiological assessment of the hunger-violence link is lacking. The current study employed data from Wave 1 (2001-2002) andWave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The NESARC is a nationally representative sample of non-institutionalized U.S. residents aged 18 years and older. Participants who experienced frequent hunger during childhood had significantly greater impulsivity, worse self-control, and greater involvement in several forms of interpersonal violence. These effects were stronger among whites, Hispanics, and males. The findings support general theoretical models implicating impulse control problems as a key correlate of crime and violence and add another facet to the importance of ameliorating food neglect in the United States. © 2016 by the authors; licensee MDPI, Basel, Switzerland.Item Field-Aligned and Lattice-Guided Tetrahedral Meshing(John Wiley & Sons Ltd.) Ni, Saifeng; Zhong, Z.; Huang, J.; Wang, W.; Guo, Xiaohu; Ni, Saifeng; Guo, XiaohuWe present a particle-based approach to generate field-aligned tetrahedral meshes, guided by cubic lattices, including BCC and FCC lattices. Given a volumetric domain with an input frame field and a user-specified edge length for the cubic lattice, we optimize a set of particles to form the desired lattice pattern. A Gaussian Hole Kernel associated with each particle is constructed. Minimizing the sum of kernels of all particles encourages the particles to form a desired layout, e.g., field-aligned BCC and FCC. The resulting set of particles can be connected to yield a high quality field-aligned tetrahedral mesh. As demonstrated by experiments and comparisons, the field-aligned and lattice-guided approach can produce higher quality isotropic and anisotropic tetrahedral meshes than state-of-the-art meshing methods.Item Upper Critical Field and Kondo Effects in Fe(Te{0.9} Se{0.1}) Thin Films by Pulsed Field Measurements(Nature Publishing Group, 2016-02-10) Salamon, Myron B.; Cornell, N.; Jaime, M.; Balakirev, F. F.; Zakhidov, Anvar A.; Huang, J.; Wang, H.; 0000 0001 0965 7058 (Salamon, MB); 0000-0003-3983-2229 (Zakhidov, AA); Salamon, Myron B.; Zakhidov, Anvar A.The transition temperatures of epitaxial films of Fe(Te{0.9} Se {0.1}) are remarkably insensitive to applied magnetic field, leading to predictions of upper critical fields B{c2}(T = 0) in excess of 100 T. Using pulsed magnetic fields, we find B{c2}(0) to be on the order of 45 T, similar to values in bulk material and still in excess of the paramagnetic limit. The same films show strong magnetoresistance in fields above B{c2}(T), consistent with the observed Kondo minimum seen above T{c}. Fits to the temperature dependence in the context of the WHH model, using the experimental value of the Maki parameter, require an effective spin-orbit relaxation parameter of order unity. We suggest that Kondo localization plays a similar role to spin-orbit pair breaking in making WHH fits to the data.
