The Architecture of Accommodation

The design process is complex. As a teacher of architecture, one of my tasks is the simplification of this process: the development of a clear set of objectives and the design of a series of tasks which move the assigned project toward completion

Hmga2 is dispensable for pancreatic cancer development, metastasis, and therapy resistance.

Expression of the chromatin-associated protein HMGA2 correlates with progression, metastasis and therapy resistance in pancreatic ductal adenocarcinoma (PDAC). Hmga2 has also been identified as a marker of a transient subpopulation of PDAC cells that has increased metastatic ability. Here, we characterize the requirement for Hmga2 during growth, dissemination, and metastasis of PDAC in vivo using conditional inactivation of Hmga2 in well-established autochthonous mouse models of PDAC. Overall survival, primary tumour burden, presence of disseminated tumour cells in the peritoneal cavity or circulating tumour cells in the blood, and presence and number of metastases were not significantly different between mice with Hmga2-wildtype or Hmga2-deficient tumours. Treatment of mice with Hmga2-wildtype and Hmga2-deficient tumours with gemcitabine did not uncover a significant impact of Hmga2-deficiency on gemcitabine sensitivity. Hmga1 and Hmga2 overlap in their expression in both human and murine PDAC, however knockdown of Hmga1 in Hmga2-deficient cancer cells also did not decrease metastatic ability. Thus, Hmga2 remains a prognostic marker which identifies a metastatic cancer cell state in primary PDAC, however Hmga2 has limited if any direct functional impact on PDAC progression and therapy resistance

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

The commissioning of the CUORE experiment: the mini-tower run

CUORE is a ton-scale experiment approaching the data taking phase in Gran Sasso National Laboratory. Its primary goal is to search for the neutrinoless double-beta decay in 130Te using 988 crystals of tellurim dioxide. The crystals are operated as bolometers at about 10 mK taking advantage of one of the largest dilution cryostat ever built. Concluded in March 2016, the cryostat commissioning consisted in a sequence of cool down runs each one integrating new parts of the apparatus. The last run was performed with the fully configured cryostat and the thermal load at 4 K reached the impressive mass of about 14 tons. During that run the base temperature of 6.3 mK was reached and maintained for more than 70 days. An array of 8 crystals, called mini-tower, was used to check bolometers operation, readout electronics and DAQ. Results will be presented in terms of cooling power, electronic noise, energy resolution and preliminary background measurements

Results from the Cuore Experiment

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double beta decay that has been able to reach the 1-ton scale. The detector consists of an array of 988 TeO2 crystals arranged in a cylindrical compact structure of 19 towers, each of them made of 52 crystals. The construction of the experiment was completed in August 2016 and the data taking started in spring 2017 after a period of commissioning and tests. In this work we present the neutrinoless double beta decay results of CUORE from examining a total TeO2 exposure of 86.3kg yr, characterized by an effective energy resolution of 7.7 keV FWHM and a background in the region of interest of 0.014 counts/ (keV kg yr). In this physics run, CUORE placed a lower limit on the decay half- life of neutrinoless double beta decay of 130Te > 1.3.1025 yr (90% C. L.). Moreover, an analysis of the background of the experiment is presented as well as the measurement of the 130Te 2vo3p decay with a resulting half- life of T2 2. [7.9 :- 0.1 (stat.) :- 0.2 (syst.)] x 10(20) yr which is the most precise measurement of the half- life and compatible with previous results

Refashioning the Ethiopian monarchy in the twentieth century: An intellectual history

This article traces the shift in the Ethiopian monarchical ideology from lineage as symbolic Christian filiation to dynasty as a political genealogy of sovereign power. From the end of the nineteenth century, and more prominently under Haylä Səllase, Ethiopian state sources started qualifying the Ethiopian ruling dynasty as ‘unbroken’ in history. A record of ‘uninterrupted’ power allowed the Ethiopian government to politically appropriate past glories and claim them as ‘ours’, thus compensating for the political weakness of the present with the political greatness of the past. The ideological rebranding of the Ethiopian monarchy in the 1930s brought Ethiopia closer to Japan, and the ‘eternalist clause’ of the Meiji constitution offered a powerful model of how to recodify dynasty in modern legal terms. An intellectual history of dynasty in the Ethiopian context sees the concept simultaneously associated with both hegemonic and counter-hegemonic political projects. The narratives of continuity enabled by the dynastisation of history were successful in invigorating the pro-Ethiopian front during the Italian occupation of Ethiopia (1936-1941), but served at the same time to reinforce domestic mechanisms of class, political and cultural domination

The decline of socialism in Washington : 1910-1925

Thesis(M.A.)--University of Washington, 1969In the fall of 1894, Eugene V. Debs, founder of the American Railway Union, began serving a sentence of six months in Jail for leading the great strike at the sleeping car works in the company town of Pullman, Illinois. Debs’ role in the strike and his imprisonment in the Woodstock jail in Illinois made him a national figure. He and his fellow inmates quickly renamed the prison the Woodstock Co-operative Colony of Liberty Jail and from around the country radicals made pilgrimages to meet the great man. Victor Berger, the well known socialist, visited Debs, leaving a volume of Capital for Debs to read. Like most of the labor leaders of the time, Debs found Marx dull, but he did enjoy the works of Karl Kautsky, a popular German socialist. Berger was followed by Kier Hardie, the fiery Scottish socialist and trade union leader, as well as by Thomas J. Morgan, a Chicago socialist. 'The three men spent hours talking about the need for an international organization which would promote friendship and solidarity among workers. They brought Debs to the edge of conversion
