Intersections in genus 3 and the Boussinesq hierarchy

In this note we prove that the enlarged Witten's conjecture is true in the case of the Boussinesq hierarchy for correlators in genus 3 with descendants only at one point

Combinatorics of binomial decompositions of the simplest Hodge integrals

We reduce the calculation of the simplest Hodge integrals to some sums over decorated trees. Since Hodge integrals are already calculated, this gives a proof of a rather interesting combinatorial theorem and a new representation of Bernoulli numbers.Comment: 16 page

Some relations for one-part double Hurwitz numbers

Magnetic anisotropy in strained manganite films and bicrystal junctions

Transport and magnetic properties of LSMO manganite thin films and bicrystal junctions were investigated. Manganite films were epitaxially grown on STO, LAO, NGO and LSAT substrates and their magnetic anisotropy were determined by two techniques of magnetic resonance spectroscopy. Compare with cubic substrates a small (about 0.3 persentage), the anisotropy of the orthorhombic NGO substrate leads to a uniaxial anisotropy of the magnetic properties of the films in the plane of the substrate. Samples with different tilt of crystallographic basal planes of manganite as well as bicrystal junctions with rotation of the crystallographic axes (RB - junction) and with tilting of basal planes (TB - junction) were investigated. It was found that on vicinal NGO substrates the value of magnetic anisotropy could be varied by changing the substrate inclination angle from 0 to 25 degrees. Measurement of magnetic anisotropy of manganite bicrystal junction demonstrated the presence of two ferromagnetically ordered spin subsystems for both types of bicrystal boundaries RB and TB. The magnitude of the magnetoresistance for TB - junctions increased with decreasing temperature and with the misorientation angle even misorientation of easy axes in the parts of junction does not change. Analysis of the voltage dependencies of bicrystal junction conductivity show that the low value of the magnetoresistance for the LSMO bicrystal junctions can be caused by two scattering mechanisms with the spin- flip of spin - polarized carriers due to the strong electron - electron interactions in a disordered layer at the bicrystal boundary at low temperatures and the spin-flip by anti ferromagnetic magnons at high temperatures.Comment: 26 pages, 10 figure

On cardinality of the lower sets and universal discretization

A set $Q$ in $\mathbb{Z}_+^d$ is a lower set if $(k_1,\dots,k_d)\in Q$ implies $(l_1,\dots,l_d)\in Q$ whenever $0\le l_i\le k_i$ for all $i$. We derive new and refine known results regarding the cardinality of the lower sets of size $n$ in $\mathbb{Z}_+^d$. Next we apply these results for universal discretization of the $L_2$-norm of elements from $n$-dimensional subspaces of trigonometric polynomials generated by lower sets

Cognitive and contextual variables in sexual partner and relationship perception

Versão pós-printThis study examined the effects of contextual and cognitive variables for sexual protection on perceived social relationship factors. University students (108 women and 108 men) read script-based narratives on sexual encounters inwhich six variables were manipulated in two independent analyses. In thefirst analysis, fourvariableswere evaluated: relational context (stable, casual), condom use (yes, no), script terminus (beginning, middleor end), andthe rater’s sex.Thedependentvariables were interpersonal perception of one of the characters of the narrative, and expectations regarding characteristics and future of the relationship. In the second analysis, two other factors were manipulated only in the‘‘yes’’condom conditions: communicationstrategy (verbal,non-verbal)andcondomproponent gender. Our findings corroborated other studies where condom use was viewed as unromantic with less positive characteristics for relationships. Condom proponents, especiallymale, were perceived as lessromantic,particularlywhenproposingacondomnon-verbally at the beginning of the encounter. However, the controlled variables enabled us to proposeways of associating condomuse withpositive expectationstowards theproponentandthe relationship itself.Romanticism, expectationof sexual intercourse, emotional proximity, and expectations of condom use in encounters where a condom was proposed increased when suggested by a woman,postponedtotheendof theencounter,andverballymentioned. Weencouragewomen to take the lead in suggesting condom use, thus empowering them since they do not have to wait for the male to make the first move
