    The Rolling Tachyon as a Matrix Model

    Full text link
    We express all correlation functions in timelike boundary Liouville theory as unitary matrix integrals and develop efficient techniques to evaluate these integrals. We compute large classes of correlation functions explicitly, including an infinite number of terms in the boundary state of the rolling tachyon. The matrix integrals arising here also determine the correlation functions of gauge invariant operators in two dimensional Yang-Mills theory, suggesting an equivalence between the rolling tachyon and QCD_2.Comment: 22pages. 3 figures. v2: added reference, fixed minor typo

    A review of symptomatic leg length inequality following total hip arthroplasty

    Leg length inequality (LLI) following total hip replacement is a complication which features increasingly in the recent literature. The definition of LLI is complicated by lack of consensus regarding radiological measurement, clinical measurement and the incomplete relationship between LLI and associated symptoms. This paper reviews 79 reports relating to LLI post hip replacement, detailing definitions and classification and highlighting patient populations prone to symptomatic LLI. While there is no universal definition of LLI, there is a broad consensus that less than 10 mm of difference on AP view plain radiographs is clinically acceptable. There are few techniques described that consistently produce a postoperative LLI of less than this magnitude. Where postoperative LLI exists, lengthening appears to cause more problems than shortening. In cases of mild LLI, non-surgical management produces adequate outcomes in the majority of cases, with functional LLI cases doing better than those with true LLI. Operative correction is effective in half of cases, even where nerve palsy is present, and remains an important option of last resort. Poor outcomes in patients with LLI may be minimised if individuals at risk are identified and counselled appropriately

    Initiation in the Puerto Rican Novel

    285 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1982.Initiation, or the rites and ordeals that mark the passage from adolescence into adulthood, has appeared in most genres of literature through the ages. In this study I examine the presence of the elements of initiation in the Puerto Rican novel. It is my intent to prove that a relationship can be established between the appearance and usage of initiation and the colonial status of Puerto Rico.I use a combination of two critical approaches: archetypal and socio-historical. By integrating these two critical methods, I create a prototype of initiation within a Puerto Rican context. This serves as a guide for the study of initiation in the individual novels. For my investigation I have selected three novels: La v(')ispera del hombre (1959) by Rene Marques, Ardiente suelo, fr(')ia estacion (1961) by Pedro Juan Soto, and El fuego y su aire (1970) by Enrique A. Laguerre.It is the presence of initiatory elements in each of these novels that provides them with a structural link. The works are also joined by the treatment of themes such as ethnicity, language, identity, and acculturation. Despite the differences in style and content, all three novels reflect the concern of the authors regarding Puerto Rico's future and her present colonial status.This dissertation is divided into five chapters. Chapter I contains an overview of Puerto Rico in terms of history, culture, society, language and other related topics. I investigate the causes of the Island's colonial condition and show how it still exists despite the changes in the last four decades. In Chapter II the steps of initiation are presented and explained, along with their application and relevance in modern literature and life. Chapters III, IV and V contain the examination of the individual novels presented in chronological order.Each of the three literary chapters includes general background information on the author and his works, a short analysis of the fictional and structural components of the novel and a detailed examination of the elements of initiation and their relationship to the colonial status of Puerto Rico.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
