Holographic RG Flows and Universal Structures on the Coulomb Branch of N=2 Supersymmetric Large n Gauge Theory

We report on our results of D3-brane probing a large class of generalised type IIB supergravity solutions presented very recently in the literature. The structure of the solutions is controlled by a single non-linear differential equation. These solutions correspond to renormalisation group flows from pure N=4 supersymmetric gauge theory to an N=2 gauge theory with a massive adjoint scalar. The gauge group is SU(n) with n large. After presenting the general result, we focus on one of the new solutions, solving for the specific coordinates needed to display the explicit metric on the moduli space. We obtain an appropriately holomorphic result for the coupling. We look for the singular locus, and interestingly, the final result again manifests itself in terms of a square root branch cut on the complex plane, as previously found for a set of solutions for which the details are very different. This, together with the existence of the single simple non-linear differential equation, is further evidence in support of an earlier suggestion that there is a very simple model --perhaps a matrix model with relation to the Calogero-Moser integrable system-- underlying this gauge theory physics.Comment: 14 pages, LaTeX, 1 figur

Umbilical hernia rupture with evisceration of omentum from massive ascites: a case report

<p>Abstract</p> <p>Introduction</p> <p>The incidence of hernias is increased in patients with alcoholic liver disease with ascites. To the best of our knowledge, this is the first report of an acute rise in intra-abdominal pressure from straining for stool as the cause of a ruptured umbilical hernia.</p> <p>Case presentation</p> <p>An 81-year-old Caucasian man with a history of alcoholic liver disease presented to our emergency department with an erythematous umbilical hernia and clear, yellow discharge from the umbilicus. On straining for stool, after initial clinical assessment, our patient noted a gush of fluid and evisceration of omentum from the umbilical hernia. An urgent laparotomy was performed with excision of the umbilicus and devitalized omentum.</p> <p>Conclusion</p> <p>We report the case of a patient with a history of alcoholic liver disease with ascites. Ascites causes a chronic increase in intra-abdominal pressure. A sudden increase in intra-abdominal pressure, such as coughing, vomiting, gastroscopy or, as in this case, straining for stool can cause rupture of an umbilical hernia. The presence of discoloration, ulceration or a rapid increase in size of the umbilical hernia signals impending rupture and should prompt the physician to reduce the intra-abdominal pressure.</p

Charles S. Johnson III \u2770

This interview was recorded as part of Myra Armstead’s 2017 course, Hist 117: Inclusion at Bard, which produced a series of oral histories with alumni/ae of color. Raised in Dayton, Ohio, Charles S. Johnson III has been dedicated to politics personally, academically, and professionally throughout his life. He came to Bard from a parochial school where his Marianist brothers and teachers encouraged “freedom of inquiry and freedom of expression.” Though he felt prepared intellectually for a Bard education, and was familiar with interracial settings, his adjustment to Annandale was largely cultural: “I remember the first time I met somebody whose parents were not together [at Bard], you know, who was the product of a divorce. That was a shock.” At times, Bard felt like more of an enclave: “It was almost a liberal ghetto in the sense that you didn’t have the same diversity of thought at Bard that you had in places in the midwest.” Considering the right-wing bastion that the Dutchess County area constituted in the sixties and seventies, Charles saw Bard as a relatively safe place: “it was townies versus folks on campus.” Charles discusses the political attitudes of Bard students during the sixties, largely in reference to the Civil Rights Movement and anti-war student activism. He recalls the moment news broke out about Martin Luther King’s assassination: “people just descended on that location [Sottery Hall] from all over campus to just be together, to try to grasp the magnitude of what was going on and the meaning–I recall being so bitter as to say to somebody, ‘It’s your country’... the shock, it was felt all over the country, it was felt at Bard as well.” In 1968, someone had dismantled the commencement tent the night before the ceremony in protest of the Vietnam War. Another person phoned in a bomb threat day-of. Charles feels “there was always some excitement related to the wider world taking place on campus in the Spring.” Charles was a witness to many political happenings of his time: “I remember being captivated by the events in Selma and I did some early writing at Bard about that. I grew up around folks who were involved in those activities.” He is also the grandson of sociologist Charles S. Johnson, whose distinguished legacy is found in the social science departments of the National Urban League and Fisk University. When asked by a student how to shape one’s community so that it is economically competitive, Charles asserts that leveraging governmental power is the key to generating economic opportunity. During his time at the Metropolitan Applied Research Center, he worked alongside civil rights activists John Lewis, Julian Bond, and Roy Innis. Georgia defined his upbringing as a political activist: “My introduction to Atlanta was with John Lewis. And through the lens of the folks who were changing the world, and certainly changing the South. So I got to meet the leadership of SCLC and the leadership of SNCC… If you show yourself as somebody who is willing to roll up your sleeves and help out, you’re welcome. And that’s the kind of reception I found coming to Atlanta.” As a Mid-Hudson Field Coordinator for Reverend King’s campaigns, Charles helped organize demonstrations like the Poor People’s Campaign and Memphis Sanitation Workers’ Strike. With regards to his career, he discusses obstacles in planning urban development, demographic shifts, and representational politics. As of 2022, he has resided on Bard’s Board of Trustees for more than a decade. Bard College presented Charles S. Johnson with the Bard Medal in 2021.https://digitalcommons.bard.edu/oral_hist/1094/thumbnail.jp

Development of Precision Livestock Farming (PLF) technologies for the Australian pig industry

The main objective of this review was to assess currently available technologies to be used in Australian Precision Livestock Farming (PLF) systems and the research and development (R&D) work required before these systems can be implemented. Commercially available hardware and software products were assessed and a literature review of current R&D was undertaken to capture emerging technologies. One of the main recommendations of the review was that the implementation of PLF systems within Australia should occur via a coordinated development and linking of existing hardware and software components. The main implementation barriers identified are data compatibility and transfer. In order to achieve these aims investment in (1) industry coordination, (2) awareness raising/training programs (3) effectively targeted R&D projects and in the (4) establishment of demonstration/research sites would be required
