Fugitive Borders

Fugitive Borders explores a new archive of 19th-century autobiographical writing by black authors in North America. For that purpose, Nele Sawallisch examines four different texts written by formerly enslaved men in the 1850s that emerged in or around the historical region of Canada West (now known as Ontario) and that defy the genre conventions of the classic slave narrative. Instead, these texts demonstrate originality in expressing complex, often ambivalent attitudes towards the so-called Canadian Promised Land and contribute to a form of textual community-building across national borders. In the context of emerging national discourses before Canada's Confederation in 1867, they offer alternatives to the hegemonic narrative of the white settler nation

The drive system of the Major Atmospheric Gamma-ray Imaging Cherenkov Telescope

The MAGIC telescope is an imaging atmospheric Cherenkov telescope, designed to observe very high energy gamma-rays while achieving a low energy threshold. One of the key science goals is fast follow-up of the enigmatic and short lived gamma-ray bursts. The drive system for the telescope has to meet two basic demands: (1) During normal observations, the 72-ton telescope has to be positioned accurately, and has to track a given sky position with high precision at a typical rotational speed in the order of one revolution per day. (2) For successfully observing GRB prompt emission and afterglows, it has to be powerful enough to position to an arbitrary point on the sky within a few ten seconds and commence normal tracking immediately thereafter. To meet these requirements, the implementation and realization of the drive system relies strongly on standard industry components to ensure robustness and reliability. In this paper, we describe the mechanical setup, the drive control and the calibration of the pointing, as well as present measurements of the accuracy of the system. We show that the drive system is mechanically able to operate the motors with an accuracy even better than the feedback values from the axes. In the context of future projects, envisaging telescope arrays comprising about 100 individual instruments, the robustness and scalability of the concept is emphasized.Comment: 15 pages, 12 (10) figures, submitted to Astroparticle Physics, a high resolution version of the paper (particularly fig. 1) is available at http://publications.mppmu.mpg.de/2008/MPP-2008-101/FullText.pd

Transnational Black Politics and Resistance from Enslavement to Obama Through the Prism of 1619

Four centuries after the 1619 arrival of forty Africans to Jamestown, marking the birth of US slavery, the year 2019 reminds us that the presence, triumphs, and struggles of African-descended people in the Atlantic world represent a history whose roots extend deep and long into the transnational origins of the so-called new world

The serine/threonine kinase Par1b regulates epithelial lumen polarity via IRSp53-mediated cell–ECM signaling

Par1b regulates cell–ECM signaling and dictates epithelial lumenal organization by targeting IRSp53, a Rho GTPase adaptor and scaffolding protein

I-BAR protein antagonism of endocytosis mediates directional sensing during guided cell migration

The I-BAR domain–containing protein, missing-in-metastasis, directs cell motility by opposing the endocytic activity of the endophilin–CD2AP–cortactin complex
