The geometry of the unipotent component of the moduli space of Weil-Deligne representations

In this paper, we study the moduli space of unipotent Weil-Deligne representations and characterise which irreducible components are smooth. We also study a certain class of unions of irreducible components, and prove that they are Cohen-Macaulay at points $(\Phi, N)$ with $\Phi$ regular semisimple. We apply the smoothness results proved earlier to show that a certain space of ordinary automorphic forms is a locally generically free module over the corresponding global deformation ring.Comment: 50 page

Research towards novel immunotherapeutic vectors: calixarene scaffolds

The aim of this project was to generate a new type of therapeutic delivery system and immunogenic vector, based on calixarenes, that is able to not only deliver immunogenic peptide but also act as a potential cancer vaccine. The introduction presents calixarenes derivatives in the context of supramolecular chemistry. Their properties on the nanoscale allow them to be potential adjuvants for cancer immunotherapeutics

Microplastic Fiber Abundance for South Carolina White Shrimp, Litopenaeus setiferus, Across Two Habitats

Coastal South Carolina is a prime destination for shrimping. The commercial White Shrimp, Litopenaeus setiferus, is one of the main species found in South Carolina estuaries and coastline. There are commercial and recreation fishing practices in South Carolina for L. setiferus, making it a species of interest for the public. Microplastics are additionally a large interest in the public and scientific community for research and solutions. The threats of plastic pollution are not fully understood in the marine environment, but there has been a boom of research discussing various effects and distributions of microplastics in the ocean recently. Shrimp species have been documented with microplastics in from various regions, such as Malaysia, Ecuador, the Southwest Atlantic, and Indian Ocean from a study using shrimps found in a Singapore market (Curren et al, 2020). In South Carolina, grass shrimp, Palaemonetes pugio, was found to contain microplastics, however there are vast differences between P. pugio and L. setiferus (Gray and Weinstein, 2017). The objective of this study was to document the abundance of microplastic fibers in the commercial white shrimp, L. setiferus, in South Carolina

Investor Behavior Surrounding Trading Halts: Short Sales, Predation and Contagion Effects

This dissertation is comprised of three essays that focus on the interaction between exchange-mandated trading halts and short selling activity in the financial markets. In the first essay, the behavior of short sellers is examined surrounding interruptions in trading to determine if informed short sellers alter their trading patterns prior to and/or following a trading halt. This investigation also addresses the impact of short sales on market quality for halted stocks surrounding periods of interrupted trading, by examining returns, price volatility, and spreads. The second essay investigates if a short-selling contagion effect exists for contemporaries of firms experiencing a trading halt. Although trading suspensions represent a firm-specific event, they may be vieas \u27contagious\u27 in the sense that they possess information relevant to other firms in the same industry. The potential for an intra-industry effect supports an examination into whether shorting levels vary significantly for organizations that are informationally related to a firm experiencing a trading halt. The impact of short sales on the market quality of these contemporary firms is also determined by examining returns, price volatility, and spreads surrounding interruptions in trading for an industry member. Market activity surrounding trading halts is examined in the third essay to determine if predatory trading occurs. This research establishes if predatory behavior is present surrounding interruptions in trading or alternatively, if trading halts eliminates the opportunity for predation. This investigation also determines if documented changes in market quality for halted firms are linked to predatory trading

OF MIMICRY AND WOMAN: A FEMINIST POSTCOLONIAL READING OF WIDE SARGASSO SEA AND THE BIGGEST MODERN WOMAN OF THE WORLD

Feminist and postcolonial studies have shown a similar concern with the production of new and more empowering subjectivities for those historically cast as subaltern in androcentric western contexts. In literature, as in criticism, concepts such as revision and subversion receive unprecedented attention as discourse, and hence narrative, begins to be seen as the very site where identity and relations of power are constructed and negotiated. Among the many women writers who sought to counterbalance the white maleness of the literary canon by giving colonized women a voice and a (hi)story are writers as diverse as the Dominican-born English writer Jean Rhys and the Canadian novelist Susan Swan. In their major fictional works, respectively Wide Sargasso Sea (1966) and The Biggest Modern Woman of the World (1983), they challenge the tradition of both literature and history by providing secondary or marginal women characters with a story of their own. Based primarily on the concepts of subversion and rearticulation proposed by Judith Butler and Homi Bhabha, this paper investigates and compares the strategies of representation employed by Rhys and Swan in the above novels with special attention to the relationship between the protagonists’ bodily experiences and the countries and cultures they stand for

Наклеп при накатке отверстий

Tolerancing has long been identified as a crucial part in the development of optical systems. It aims at finding the best balance between quality and cost as tolerances closely tie together manufacturing expenses and performance. Tolerance effects have been included into the optimization function (merit function) by some lens designers to find insensitive designs1-5 and frequently compensators are employed to further improve the performance of assembled lenses. Compensators are limited to a small number of system parameters, but selective assembly of components can extend the number of parameters available for compensation. It can be employed to reduce tolerance effects of disturbed parameters by finding the best matches out of a set of components. In this work we discuss how desensitization and selective assembly can be combined to loosen tolerances and increase as-built performance. The investigations concentrate on tolerance insensitive design forms under the presence of selective assembly compensators. In contrast to desensitizing a given lens or introducing new design means we focus on introducing new assembly strategies into the design procedure and investigate how using selective assembly as a compensator while desensitizing the remaining design parameters can lead to even less sensitive designs

The EAUH was founded in 1989 by English, Dutch, Belgian, and French historians. The focus of its activities is the International Conference on Urban History. It takes place every two years in a significant European city. After Amsterdam 1992, Strasbourg, Budapest, Venice, and Berlin each hosted the conference consecutively. It has become one of the biggest and most important forums for international academic exchange in the field of historic urban research
