Tunneling Spectroscopy and Vortex Imaging in Boron-Doped Diamond
We present the first scanning tunneling spectroscopy study of
single-crystalline boron doped diamond. The measurements were performed below
100 mK with a low temperature scanning tunneling microscope. The tunneling
density of states displays a clear superconducting gap. The temperature
evolution of the order parameter follows the weak coupling BCS law with
. Vortex imaging at low magnetic field also
reveals localized states inside the vortex core that are unexpected for such a
dirty superconductor.Comment: 4 pages, 4 figures, replaced with revised versio
Obstacles to Graduation: A Look at Poverty’s Effect on Academic Work
Our presentation was aimed at providing a thorough overview of concepts that interfere with an adolescent’s ability to stay in school and graduate. Additionally, the presentation addressed what other factors of poverty, such as risk-taking behaviors (e.g., marijuana use, binge drinking, or sexual activity), might carry over into college life and affect a student’s academic career. Variables connected to family community, family responsibilities, and adolescents’ self-esteem were described as well. Finally, the presentation discussed factors that play into a student’s willingness to seek out college campus resources for support. With this paper, we hope to outline variables that lead to academic drawbacks within our youth and to raise awareness about the multi-faceted phenomenon of retention of students
Quantitative analysis of metastability in reversible diffusion processes via a Witten complex approach
Nous calculons de façon précise les premières valeurs propres, exponentiellement petites, du Laplacien de Witten sur les 0-formes. Ces quantités sont liées au taux de retour à l\'équilibre pour des processus stochastiques réversibles.Lápproche proposée ici repose sur la structure du complexe de Witten et donne des résultats plus précis et généraux que les méthodes probabilistes
A second anniversary operational review of the OmniTRACS(R): The first two-way mobile Ku-band satellite communications system
A novel two-way mobile satellite communications and vehicle position reporting system that is currently operational in the United States and Europe is described. The system characteristics and service operations are described in detail. Technical descriptions of the equipment and signal processing techniques are provided
Anomalous metallic state in quasi-two-dimensional BaNiS
We report on a systematic study of the thermodynamic, electronic and charge
transport properties of high-quality single crystals of BaNiS, the metallic
end-member of the quasi-twodimensional BaCoNiS system
characterized by a metal-insulator transition at . Our analysis of
magnetoresistivity and specific heat data consistently suggests a picture of
compensated semimetal with two hole- and one electron-bands, where
electron-phonon scattering dominates charge transport and the minority holes
exhibit, below 100 K, a very large mobility, 15000
cmVs, which is explained by a Dirac-like band. Evidence of
unconventional metallic properties is given by an intriguing crossover of the
resistivity from a Bloch-Gr\"uneisen regime to a linear regime occurring at
2 K and by a strong linear term in the paramagnetic susceptibility above 100 K.
We discuss the possibility that these anomalies reflect a departure from
conventional Fermi-liquid properties in presence of short-range AF fluctuations
and of a large Hund coupling.Comment: 21 pages 9 figures (colors
Commentary “The sexualized-body-inversion hypothesis revisited: Valid indicator of sexual objectification or methodological artifact?”
A commentary on The sexualized-body-inversion hypothesis revisited: Valid indicator of sexual objectification or methodological artifact? by Schmidt, A. F., and Kistemaker, L. M. (2015). Cognition 134, 77-84. doi: 10.1016/j.cognition.2014.09.003
Recent objectification research found results consistent with the sexualized body-inversion hypothesis (SBIH): People relied on analytic, “object-like” processing when recognizing sexualized female bodies and on configural processing when recognizing sexualized male bodies (Bernard et al., 2012). Specifically, Bernard et al. (2012) showed that perceivers were better at recognizing sexualized male bodies when the bodies were presented upright than upside down, whereas this pattern did not emerge for sexualized female bodies; thus, male bodies were recognized configurally similar to other human stimuli whereas female bodies were recognized analytically, similarly to most objects (see Kostic, 2013 for an exact replication). Based on two studies, Schmidt and Kistemaker (2015) concluded that Bernard et al. (2012)\u27s findings were: (i) due to a symmetry confound; (ii) not due to target\u27s sexualization. This commentary challenges these conclusions

Leadership during a racial microaggression on campus
The study aimed at understanding students’ perspectives on university response to a racial microaggression on a campus. Responses were collected in the form of an online survey and analyzed using qualitative data analysis to identify themes from students’ perspective. Insights about how students processed the incident were gained. Although students were thankful of the university response, concern for another incident, and how leadership will equip students to handle situations lingers. Implications for educators are provided
