J/ψ\psi and ψ(2S)\psi(2S) measurement in p+p collisions at s=\sqrt{s} = 200 and 500 GeV with the STAR experiment

In this paper, results on the J/psi cross section and polarization measured via the dielectron decay channel at mid-rapidity in p+p collisions at 200 and 500 GeV in the STAR experiment are discussed. Also, first measurements of the J/psi production as a function of the charged-particle multiplicity density and of psi(2S) to J/psi ratio at 500 GeV are reported.Comment: 4 pages, 3 figures, Proceedings for Strangeness in Quark Matter 2015 conference, July 6-11, 2015, Dubna, Russi

Taboo, the Game: Patent Office Edition—The New Preissuance Submissions Under the America Invents Act

Thorough patent examination ensures that issued patents confer constitutionally granted incentives to innovate but do not create inappropriately broad monopolies. Examiners at the United States Patent and Trademark Office are alone tasked with striking this proper balance, in part by searching the universe of existing published knowledge to determine the originality of the applied-for invention. In 2011, Congress enacted the Leahy-Smith America Invents Act, which included a provision allowing the public to present examiners with relevant publications that the examiners’ own searches might not otherwise uncover. However, this “preissuance submissions” provision and its related administrative rule are tempered by 35 U.S.C. § 122(c) (2006), which prohibits any third-party, pre-grant “protest or other form of [preissuance] opposition” to an application. Thus, although a party may describe to an examiner how its submission is relevant to an application, that party is prohibited from arguing how the submission renders that application unpatentable. This Note argues that Congress should amend § 122(c) to permit preissuance third-party argumentation for two reasons. First, the current scheme arguably violates that law already. Second, a rule allowing submitter argumentation would better incentivize participation by competitive parties who fear that examiners might not recognize their submitted publications\u27 full invalidating potential

J/ψ\psi polarization in p+p collisions at s\sqrt{s} = 200 GeV in STAR

In this paper, J/$\psi$ polarization at mid-rapidity in $p+p$ collisions at $\sqrt{s}$ = 200 GeV measured in the STAR experiment at RHIC is reported. J/$\psi$ production is analyzed via the dielectron decay channel. J/$\psi$ polarization is extracted from the decay angular distribution in the helicity frame. The J/$\psi$ polarization is measured at transverse momentum range (2 - 6) GeV/c and is found to be consistent with $NLO^+$ Color Singlet Model ($NLO^+$ CSM), Color Octet Model (COM) predictions and with no polarization within current uncertainties.Comment: 6 pages, 4 figure, Proceedings of the International Conference on Strangeness in Quark Matter 2011 (SQM2011), Krakow, Poland, September 18-24, 201

Genotoxicity of the organophosphorus compound methylparaoxon evaluated by the comet assay

Pesticides are widely used in agriculture, food production and household. Due to the broad spectrum of their activity, their biological action is extensively investigated. We assessed the genotoxidty of methylparaoxon - the main metabolite of commonly used organophosphorus insecticide, methylparathion. Freshly isolated human peripheral blood lymphocytes were incubated for 1 h with methylparaoxon at 37° C, and then, were incubated in methylparaoxon-free medium to examine DNA repair. Alkaline single cell gel electrophoresis (the comet assay) was used to assess DNA damage and repair. Methylparaoxon induced moderate DNA damages that were almost completely repaired after 60 min. Obtained results suggest that methylparaoxon could induce single-strand breaks in DNA both directly and by methylathion of DNA bases.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
