DRIFT: Art and Dark Matter
No full textWhat do we desire from the imperceptible? Four artists were invited to travel deep underground to SNOLAB to think with dark matter, an invisible matter that is having a gravitational effect on everything. Without this “dark” matter, galaxies would fly apart, according to observational data in astroparticle physics. Given the contours of such a “known unknown,” Nadia Lichtig, Josèfa Ntjam, Anne Riley, and Jol Thoms reflect on the how and why of physics and art as interrelating practices. The artists’ widely varied and challenging responses include expressions of new kinds of sensitivity and poetic freedom, questions about the task of knowledge, and cartographies of entangled social and ecological relations. Thinking across disciplines, they have created works that connect scientific ideas of dark matter with a far-reaching care for that which has not been sensed. Could this work excite stealthy solidarities of curiosity across (and despite) art and science?

'If I should die tonight' poem
No full textHumorous poem copied by Harrison Kerr and written by Benjamin Franklin King ca. 1890. The poem, titled "If I should die tonight," jokes about money owed to the author and the shock he would experience at being repaid upon his death. It was written as a parody of a serious contemporary poem of the same title.
Harrison Henry Kerr (1839-1901), born in North Georgetown, Ohio, served along with his brother, Ezra, as a private in Company D of the 58th Ohio Volunteer Infantry. He was taken prisoner at the Battle of Chickasaw Bayou, Mississippi, on December 29, 1862., and held for three months before being exchanged and returning to his regiment. He was discharged on January 14, 1865. Following the war, he was married to Elizabeth (Rettig) Kerr. The two lived in Cleveland and had one son, Harrison McKinley Kerr. In 1888, he joined the Memorial Post No. 141, Grand Army of the Republic. He is buried in North Georgetown Cemetery
Experimental validation of nonlinear Fourier transform-based Kerr-nonlinearity identification over a 1600km SSMF link
No full textRecently, a nonlinear Fourier transform-based Kerr-nonlinearity identification algorithm was demonstrated for a 1000 km NZDSF link with accuracy of 75%. Here, we demonstrate an accuracy of 99% over 1600 km SSMF. Reasons for improved accuracy are discussed.Accepted Author ManuscriptTeam Sander Wahl
International Harmonization and the Gains from Trade
No full textInternational harmonization of standards and regulations is often a goal expressed in trade agreements because it is expected to yield gains from trade. Absence of progress toward harmonization is often interpreted as being motivated by protectionism, with differences in standards and regulations seen as non-tariff barriers. While protectionism may well be the source of resistance to harmonization, there may be other reasons it is not pursued. These alternative explanations have not received much attention from economists. In this article some of these alternatives are outlined - demand effects from altering standards, switching costs, proprietary technologies. The article concludes that proposals for international harmonization need to be scrutinized carefully.demand effects, harmonization, regulation, standards, switching costs, TBT, International Relations/Trade,
Magnetised Kerr/CFT correspondence
No full textAbstractThe tools of Kerr/CFT correspondence are applied to the Kerr black hole embedded in an axial external magnetic field. Its extremal near horizon geometry remains a warped and twisted product of AdS2×S2. The central charge of the Virasoro algebra, generating the asymptotic symmetries of the near horizon geometry, is found. It is used to reproduce, via the Cardy formula, the Bekenstein–Hawking entropy of the magnetised Kerr black hole as the statistical microscopic entropy of a dual CFT. The presence of the background magnetic field makes available also a second dual CFT picture, based on the U(1) electromagnetic symmetry, instead of the only rotational one of the standard non-magnetised Kerr spacetime.A Meissner-like effect, where at extremality the external magnetic field is expelled out of the black hole, allows us to infer the value of the mass for these magnetised extremal black holes.The generalisation to the CFT dual for the magnetised extreme Kerr–Newman black hole is also presented
