P-union and P-intersection of neutrosophic cubic sets
Conditions for the P-intersection and P-intersection of falsity-external (resp. indeterminacy-external and truth-external) neutrosophic cubic sets to be an falsity-external (resp. indeterminacy-external and truthexternal) neutrosophic cubic set are provided. Conditions for the Punion and the P-intersection of two truth-external (resp. indeterminacyexternal and falsity-external) neutrosophic cubic sets to be a truthinternal (resp. indeterminacy-internal and falsity-internal) neutrosophic cubic set are discussed
NEUTROSOPHIC CUBIC SETS
The aim of this paper is to extend the concept of cubic sets to the neutrosophic sets. The notions of truth-internal (indeterminacy-internal, falsity-internal) neutrosophic cubic sets and truth-external (indeterminacy-external, falsity-external) neutrosophic cubic sets are introduced, and related properties are investigated

Small scale rotational disorder observed in epitaxial graphene on SiC(0001)
Interest in the use of graphene in electronic devices has motivated an
explosion in the study of this remarkable material. The simple, linear Dirac
cone band structure offers a unique possibility to investigate its finer
details by angle-resolved photoelectron spectroscopy (ARPES). Indeed, ARPES has
been performed on graphene grown on metal substrates but electronic
applications require an insulating substrate. Epitaxial graphene grown by the
thermal decomposition of silicon carbide (SiC) is an ideal candidate for this
due to the large scale, uniform graphene layers produced. The experimental
spectral function of epitaxial graphene on SiC has been extensively studied.
However, until now the cause of an anisotropy in the spectral width of the
Fermi surface has not been determined. In the current work we show, by
comparison of the spectral function to a semi-empirical model, that the
anisotropy is due to small scale rotational disorder ( 0.15)
of graphene domains in graphene grown on SiC(0001) samples. In addition to the
direct benefit in the understanding of graphene's electronic structure this
work suggests a mechanism to explain similar variations in related ARPES data.Comment: 5 pages, 4 figure
Highly p-doped graphene obtained by fluorine intercalation
We present a method for decoupling epitaxial graphene grown on SiC(0001) by
intercalation of a layer of fluorine at the interface. The fluorine atoms do
not enter into a covalent bond with graphene, but rather saturate the substrate
Si bonds. This configuration of the fluorine atoms induces a remarkably large
hole density of p \approx 4.5 \times 1013 cm-2, equivalent to the location of
the Fermi level at 0.79 eV above the Dirac point ED .Comment: 4 pages, 2 figures, in print AP
Association between childhood adversities and adulthood depressive symptoms in South Korea: Results from a nationally representative longitudinal study
Objective To examine how childhood adversity (ie, parental death, parental divorce, suspension of school education due to financial strain or being raised in a relative\u27s house due to financial strain) is associated with prevalence and incidence of adulthood depressive symptoms and whether this association differs by gender and by age in South Korea. Design Prospective cohort design. Setting Nationally representative longitudinal survey in South Korea. Participants 11 526 participants in South Korea. Outcome measure Prevalence and incidence of adulthood depressive symptoms were assessed as a dichotomous variable using the Centers for Epidemiologic Studies Depression (CES-D) Scale in 2006 and 2007. Results In the prevalence analysis, each of the four childhood adversities was significantly associated with a higher prevalence of adulthood depressive symptoms. The higher incidence of depressive symptoms was associated with suspension of school education (OR 1.55, 95% CI 1.32 to 1.82) and parental divorce (OR 1.65, 95% CI 1.00 to 2.71). In the age-stratified analyses, prevalence of depressive symptoms was associated with all CAs across different adulthoods, except for parental divorce and late adulthood depressive symptoms. After being stratified by gender, the association was significant for parental divorce (OR 3.76, 95% CI 2.34 to 6.03) in the prevalence analysis and for being raised in a relative’s house (OR 1.89, 95% CI 1.21 to 2.94) in the incidence analysis only among women. Conclusions This study suggests that childhood adversity may increase prevalence and incidence of adulthood depressive symptoms, and the impact of parental divorce or being raised in a relative\u27s house due to financial strain on adulthood depressive symptoms may differ by gender
