The FRT-Construction via Quantum Affine Algebras and Smash Products

For every element w in the Weyl group of a simple Lie algebra g, De Concini, Kac, and Procesi defined a subalgebra U_q^w of the quantized universal enveloping algebra U_q(g). The algebra U_q^w is a deformation of the universal enveloping algebra U(n_+\cap w.n_-). We construct smash products of certain finite-type De Concini-Kac-Procesi algebras to obtain ones of affine type; we have analogous constructions in types A_n and D_n. We show that the multiplication in the affine type De Concini-Kac-Procesi algebras arising from this smash product construction can be twisted by a cocycle to produce certain subalgebras related to the corresponding Faddeev-Reshetikhin-Takhtajan bialgebras.Comment: 15 page

Structure Elucidation of a Pyrrolobenzodiazepine Alkaloid and a Biologically Active Polyketide Produced by Rhodococcus sp. MTM3W5.2 via Two-Dimensional NMR Spectroscopy

As the battle against ever-increasing drug resistence bacteria rages on, novel and sometimes more complex natural products can be used to combat this. In this study, two-dimensional NMR techniques were utilized to collect a complete spectral data set for two natural products. The first structure, a synthesized Pyrrolobenzodiazepine alkaloid natural product was confirmed through these methods. The second, a strain of Rhodococcus, MTM3W5.2, produces a novel antibacterial molecule in broth cultures and the active compound was fractionated using a Sephedex LH-20 column. Chromatographic purification yielded a pure sample at 58.90 minutes, RT.58. HRMS data deduced an exact mass of 911.5490 Da, equivalent to a molecular formula of C52H78O13. Several major spin systems were constructed from the 2D-NMR spectra. However, due to limited sample quantity in compound with a large molecular weight and product instability, the long range HMBC signals needed to connect these fragments have not yet been obtained

The historical construction of the Native American other and U.S. self: a conceptually schizophrenic perspective

This Thesis traces and analyzes the historical antecedents that have led to a conceptually schizophrenic image of the Native American Other, as constructed within dominant U.S. discourses. The Thesis argues that this conceptual schizophrenia, a term borrowed from J. Marshall Beier, has been highly productive in justifying and maintaining U.S. hegemony over North American Indigenous peoples, communities, and nations. The Thesis develops a fluid historical materialist framework in order to analyze the role that capital development plays in continually shaping and developing this schizophrenic perspective. The schizophrenic perspective is not static, but fluid, and it is this fluidity that allows for consistent reimaginings of the Native American Other. This consistent reimagining of the Native American Other has continually served to justify U.S. dominance over Indigenous populations, and should not be seen as a result of an altruistic enlightenment of thought. This is to say, that the development of the dominant image of the Native American Other has not been an evolution or progression of a more authentic form of recognition, but is rather, simply a re-contextualization that serves to maintain entrenched power structures. Secondly, the Thesis examines how this schizophrenic framework has been productive in masking the incongruity between iniquitous U.S. action towards Indigenous peoples, land, and resources and the benign narrative tropes that have been instrumental in shaping the image of the U.S. national self. In the conclusion, the Thesis coalesces these ideas in order to analyze the contemporary failings of a politics of recognition

The Challenges Facing Autonomous Vehicles and The Progress in Addressing Them

Autonomous vehicles are an emerging technology that faces challenges, both technical and socioeconomic. This paper first addresses specific technical challenges, such as parsing visual data, communicating with other entities, and making decisions based on environmental knowledge. The technical challenges are to be addressed by the fields of image processing, Vehicle to Everything Communication (V2X), and decision-making systems. Non-technical challenges such as ethical decision making, social acceptance, and economic pushback are also discussed. Ethical decision making is discussed in the framework of deontology vs utilitarianism, while social acceptance of utilitarian autonomous vehicles is also investigated. Last, the likely economic impact is described

Computer synthesis of spectroradiometric images for color imaging systems analysis

A technique to perform full spectral based color calculations through an extension of OpenGL has been created. This method of color computations is more accurate than the standard RGB model that most computer graphics algorithms utilize. By maintaining full wavelength information in color calculations, it is also possible to interactively simulate and display many important color phenomena such as metamerism and fluorescence. This technique is not limited to creating simple images suitable for interactive display, however. Using this extension, it is also possible to synthesize spectroradiometric images of arbitrary spatial and spectral resolution, for use in color imaging system analysis

“A More Perfect World”: Posthumanism and Technological Integration in A Memory Called Empire

This thesis considers the relationship of technology to the human through a posthumanist lens, questioning what will become of the human an increasingly more-than-human world through an examination of the novel A Memory Called Empire, by Arkady Martine. Through an examination of the imago device from the novel, the thesis evaluates the human experience of memory and the influence of empire. The thesis advances four key concepts: 1. The collapsed divide between the human and the technic through memory and imagination; 2. Technology’s development and use; 3. The user that is integrated with the technic; and 4. The poisonous influence of empire. The thesis argues that these four ideas are significant because of the power of the imagination to shape the future, the influence of empire on these imaginings, and the danger of an anthropocentric approach to these imaginations. Ultimately, posthumanism explored in A Memory Called Empire presents a potential model for the integration of technology with the human, an integration that can affirm the human qualities of memory and imagination and can integrate with the technic
