SUMMARY:Lecture / Discussion:Archaeologies of Contemporary Migration: Border Assemblages\, Global Apartheid\, and the Decolonial Potential
DESCRIPTION:18th Annual Dimitris and Irmgard Pallas Modern Greek Lecture\n\nSummary: \nSince 2016\, I have been carrying out an archaeological ethnography project on contemporary migration\, focusing on the border island of Lesvos. In this talk\, I will report on some of the findings of this project\, showing how a sustained and detailed attention to the materiality and temporality of the phenomenon\, to the sensorial\, affective\, and temporal properties of things\, can offer insights that elude other kinds of research. Objects\, spaces\, buildings and landscapes are essential components in the formation of border assemblages\, together with border crossers\, volunteers\, as well as border guards and security apparatuses. I will explore how the attention to such assemblages can not only help us understand what some scholars have described as the new Global Apartheid\, but more positively\, allow us to imagine a decolonial present and future. \n\nBiography: \nYannis Hamilakis is Joukowsky Family Professor of Archaeology and Professor of Modern Greek Studies at Brown University. He worked previously at the Universities of Wales Lampeter (1996-2000) and the University of Southampton (2000-2016)\, and he has held research fellowships at Princeton University\, Getty Research Institute\, Cincinnati University\, The Institute of Advanced Studies at Princeton\, and the Remarque Institute at NYU. His research interests include Aegean prehistory\, the socio-politics of the past\, the bodily senses\, archaeology and photography\, contemporary archaeology\, and the materiality of contemporary migration. His books include\, The Nation and Its Ruins: Antiquity\, Archaeology\, and National Imagination in Greece (OUP\, 2007\, Edmund Keeley Book Prize 2009)\, and Archaeology and the Senses: Human Experience\, Memory\, and Affect (CUP\, 2013). His most recent book is the edited volume\, The New Nomadic Age: Archaeologies of Forced and Undocumented Migration. (Equinox\, 2018). He co-directs the Koutroulou Magoula Archaeology and Archaeological Ethnography Project\, and in 2020 he will be curating an exhibition at the Haffenreffer Museum of Anthropology at Brown University\, entitled\, Transient Matter: Border Assemblages in the Mediterranean.

SUMMARY:Workshop / Seminar:HEP-Astro Seminar | Ultra-Low Energy Calibration of the LUX and LZ Dark Matter Detectors
DESCRIPTION:The Large Underground Xenon (LUX) experiment is a 250 kg active mass dual-phase time-projection chamber (TPC) operating at the 4850 ft level of the Sanford Underground Research Facility in Lead\, SD. Various sources\, including ^{127}Xe\, D-D neutrons\, ^{83}mKr\, Tritium\, and AmBe neutrons are used to perform calibrations of detector responses to electron recoils (ER) and nuclear recoils (NR). I will present an ultra-low energy calibration of ER using an intrinsic ^{127}Xe source and of NR using a short pulsed D-D neutron generator. Radioactive isotope ^{127}Xe is formed in the LUX LXe volume due to cosmogenic activation before the detector was moved one mile underground. A measurement in the early stage of the LUX WS2013 science run unveils ~0.9 million ^{127}Xe atoms in the LUX LXe volume\, which provides an ideal source for low energy calibrations. ^{127}Xe decay is a form of electron capture in which a high energy gamma (> 200 keV) is emitted\, followed by an associated low energy X-ray cascade over the energy range of 190 eV to 33.2 keV. The relatively long mean free path (mfp) of the gamma-ray (> 0.9 cm) allows the EC decay to produce clearly identified 2-vertex events in the LUX detector. We observe the K (33.2 keV)\, L (5.2 keV)\, M (1.1 keV)\, and N (190 eV) shell cascade events and verify the relative ratio of observed events for each shell. We extract the means and sigmas of the charge signal yields associated with the K\, L\, M\, and N shell events. The N shell cascade analysis includes single extracted electron (SE) events and represents the lowest-energy electronic recoil in situ measurements that have been explored in liquid xenon. A short pulsed D-D neutron NR calibration was performed in situ in the LUX detector in June 2016 after the completion of the LUX WS2013-16 science run. The calibration incorporates a pulsing technique with narrow pulses (20 us / 250 Hz). We have measured\, with low systematics\, the absolute rates of NR events with ionization signals down to 2 extracted electrons and zero\, one or greater detected scintillation photons. A calibration measurement with absolute event rates of charge-only S2 events for the first time in a Xe TPC provides an important probe for ultra-low energy measurements of LXe Qy. This technique provides direct measurements of scintillation and charge yields down to (Ly) 0.45 keVnr and (Qy) 0.27 keVnr\, respectively. New calibration results on ultra-low energy nuclear recoil yields are crucial to determine physics search sensitivities for large mass LXe TPCs (LZ experiment) for low mass WIMPs (< 10 GeV) and for coherent neutrino scattering (e.g. ^8B solar neutrino).\n\n

SUMMARY:Lecture / Discussion:Honors Stowe Lectures
DESCRIPTION:Anu Partanen speaks frequently about topics related to her book \"The Nordic Theory of Everything: In Search of a Better Life\,\" both internationally and in the United States. Read more about this guest speaker and author on their website in Web & Social Media Links. \n\nThe lecture celebrates the best in journalism\, broadly understood. Stowe was a Pulitzer Prize winner in 1930 and one of the early American journalists to raise concerns about Hitler’s rise to power. During World War II\, he was a war correspondent. He was a Professor of Journalism at the University of Michigan 1956–1969 and died in 1994.
