Accurate Determination of the Neutron Skin Thickness of ^{208}Pb through Parity-Violation in Electron Scattering.

Abstract: We report a precision measurement of the parity-violating asymmetry A_{PV} in the elastic scattering of longitudinally polarized electrons from ^{208}Pb. We measure A_{PV}=550±16(stat)±8(syst) parts per billion, leading to an extraction of the neutral weak form factor F_{W}(Q^{2}=0.00616 GeV^{2})=0.368±0.013. Combined with our previous measurement, the extracted neutron skin thickness is R_{n}-R_{p}=0.283±0.071 fm. The result also yields the first significant direct measurement of the interior weak density of ^{208}Pb: ρ_{W}^{0}=-0.0796±0.0036(exp)±0.0013(theo) fm^{-3} leading to the interior baryon density ρ_{b}^{0}=0.1480±0.0036(exp)±0.0013(theo) fm^{-3}. The measurement accurately constrains the density dependence of the symmetry energy of nuclear matter near saturation density, with implications for the size and composition of neutron stars.

Cyberbullying: What School Administrators (and Parents) Can Do

Abstract: Technology has transformed the lives of adolescents, including the ways they bully one another. Variously referred to as electronic bullying, online bullying, or cyberbullying, this new method of bullying involves the use of e-mail, instant messaging, Web sites, voting booths, and chat or bash rooms to deliberately pick on and torment others. To combat cyberbullying, educators need to better understand the nature of it and be aware of actions that they can undertake to prevent cyberbullying in the schools.

The Many Faces of Turbine Surface Roughness

Abstract: Results are presented for contact stylus measurements of surface roughness on in-service turbine blades and vanes. Nearly 100 turbine components were assembled from four land-based turbine manufacturers. Both coated and uncoated, cooled and uncooled components were measured, with part sizes varying from 2 to 20 cm. Spanwise and chordwise two-dimensional roughness profiles were taken on both pressure and suction surfaces. Statistical computations were performed on each trace to determine centerline averaged roughness, rms roughness, and peak to-valley height. In addition, skewness and kurtosis were calculated; as well as the autocorrelation length and dominant harmonics in each trace. Extensive three-dimensional surface maps made of deposits, pitting, erosion, and coating spallation expose unique features for each roughness type. Significant spatial variations are evidenced and transitions from rough to smooth surface conditions are shown to be remarkably abrupt in some cases. Film cooling sites are shown to be particularly prone to surface degradation.

Are There Religious Variations in Domestic Violence

Abstract: Religious variations in domestic violence remain understudied. Arguments are developed linking aspects of religious affiliation, practice, theology, and couples' religious (dis)similarities with domestic violence. These relationships are then examined via gender-specific models of data from the first wave of the National Survey of Families and Households (NSFH-1). The authors find that regular attendance at religious services is inversely associated with self-reported perpetration of domestic violence for men and women. Denominational homogamy (i.e., same-faith vs. mixed-faith relationships) has little bearing on the likelihood of abuse. Other forms of religious dissimilarity do appear to heighten the risk of abuse. In particular, men who hold much more conservative theological views than their partners are especially likely to perpetrate domestic violence. The implications of these and other findings are discussed, and several promising directions for further research are identified.

Taxonomy of the order Bunyavirales : update 2019

Abstract: In February 2019, following the annual taxon ratification vote, the order Bunyavirales was amended by creation of two new families, four new subfamilies, 11 new genera and 77 new species, merging of two species, and deletion of one species. This article presents the updated taxonomy of the order Bunyavirales now accepted by the International Committee on Taxonomy of Viruses (ICTV).
