Multiresolution Inverse Wavelet Reconstruction From A Fourier Partial Sum, Nataniel Greene

Publications and Research

The Gibbs phenomenon refers to the lack of uniform convergence which occurs in many orthogonal basis approximations to piecewise smooth functions. This lack of uniform convergence manifests itself in spurious oscillations near the points of discontinuity and a low order of convergence away from the discontinuities.In previous work [11,12] we described a numerical procedure for overcoming the Gibbs phenomenon called the Inverse Wavelet Reconstruction method (IWR). The method takes the Fourier coefficients of an oscillatory partial sum and uses them to construct the wavelet coefficients of a non-oscillatory wavelet series. However, we only described the method standard wavelet series and …

Teaching The Process Of Molecular Phylogeny And Systematics: A Multi-Part Inquiry-Based Exercise, Nathan H. Lents, Oscar E. Cifuentes, Anthony Carpi

Publications and Research

Three approaches to molecular phylogenetics are demonstrated to biology students as they explore molecular data from Homo sapiens and four related primates. By analyzing DNA sequences, protein sequences, and chromosomal maps, students are repeatedly challenged to develop hypotheses regarding the ancestry of the five species. Although these exercises were designed to supplement and enhance classroom instruction on phylogeny, cladistics, and systematics in the context of a postsecondary majors-level introductory biology course, the activities themselves require very little prior student exposure to these topics. Thus, they are well suited for students in a wide range of educational levels, including a biology …

Survivalism And Public Opinion On Criminality: A Cross-National Analysis Of Prostitution, Steven Stack, Amy Adamczyk, Liqun Cao

Publications and Research

Explanations of variability in public opinion on crime have drawn disproportionately from the literature on specific symbolic orientations including religious fundamentalism and racial prejudice. In contrast, this article hypothesizes that public opinion is linked to the strength of a general cultural axis of nations: survivalism vs. self-expressionism. Data are from the fourth wave of the World Values Survey. Hierarchical modeling techniques are used to sort out the bi-level effects of survivalist culture on the approval of prostitution. Controlling for all other predictors, the personal survivalism index was the most powerful predictor of prostitution acceptability, followed by the country-level survivalism index. …

Demystifying The Irb: Human Subjects Research In Academic Libraries, Maura A. Smale

Publications and Research

Many academic librarians are interested in pursuing research studies that involve students, faculty, and other library patrons; these projects must be approved by an institutional review board (IRB). This article reviews federal requirements and regulations for human subjects research and explains the IRB application process. The author discusses common types of research projects undertaken by academic librarians that require IRB approval and offers suggestions for successful navigation through the IRB process. Academic librarians should embrace research involving human subjects because the results contribute to the corpus of scholarly knowledge in library and information science as well as in higher education.

Introductory Research For Inner-City Advanced Placement High School Students, Keith Muchowski

Publications and Research

Gloria E. Anzaldúa’S Decolonizing Ritual De Conocimiento, Sarah S. Ohmer

Publications and Research

Gloria E. Anzaldúa’s work makes up one of the many Chican@ works that contribute another history, a history repressed by the national discourses on both sides of the border. Influenced by antecedents of U.S. Hispanic Literature who superposed “official” history with another history, Chicano activists had already enacted a retrieval of pre-conquest histories to revive their people’s historical consciousness. As Saldívar-Hull states in “Mestiza Consciousness and Politics: Gloria Anzaldúa’s Borderlands/ La frontera,” the publication of Borderlands/ La Frontera distinguished itself from the Chicano movement’s as it unveiled the curtain that hid the Aztec goddesses and kept aspects of pre-conquest history …

Single Magnetic Molecule Between Conducting Leads: Effect Of Mechanical Rotations, Reem Jaafar, Eugene M. Chudnovsky, Dmitry A. Garanin

Publications and Research

We study spin-rotation effects in a magnetic molecule bridge d between two conducting leads. Dy- namics of the total angular momentum couples spin tunneling to the mechanical rotations. Landau- Zener spin transition produced by the time-dependent magne tic field generates a unique pattern of mechanical oscillations that can be detected by measuring t he electronic tunneling current through the molecule.

Rotational States Of Magnetic Molecules, Eugene M. Chudnovsky, Dmitry A. Garanin

Publications and Research

We study a magnetic molecule that exhibits spin tunneling and is free to rotate about its anisotropy axis. Exact low-energy eigenstates of the molecule that are superpositions of spin and rotational states are obtained. We show that parameter α=2(ℏS)2/(IΔ) determines the ground state of the molecule. Here ℏS is the spin, I is the moment of inertia, and Δ is the tunnel splitting. The magnetic moment of the molecule is zero at α<αc=[1−1/(2S)2]−1 and non-zero at α>αc. At α→∞ the spin of the molecule localizes in one of the directions along the anisotropy axis.

Rotational Doppler Effect In Magnetic Resonance, S Ledinez, Eugene M. Chudnovsky, Javier Tejada

Publications and Research

We compute the shift in the frequency of the spin resonance in a solid that rotates in the field of a circularly polarized electromagnetic wave. Electron spin resonance, nuclear magnetic resonance, and ferromagnetic resonance are considered. We show that contrary to the case of the rotating LC circuit, the shift in the frequency of the spin resonance has strong dependence on the symmetry of the receiver. The shift due to rotation occurs only when rotational symmetry is broken by the anisotropy of the gyromagnetic tensor, by the shape of the body, or by magnetocrystalline anisotropy. General expressions for the resonance …

Dipolar Ordering In Crystals Of Mn12 Ac, Dmitry A. Garanin

Publications and Research

Ordering in realistic elongated box-shape crystals of the molecular magnet Mn_12 Ac is investigated with the site-resolved mean-field approximation that does not assume a uniform ordering. It is shown that ferromagnetic ordering should not occur in crystals with the aspect ratio up to 12. Instead, for the aspect ratio about 6, the inner and outer regions of the crystal order in different directions, uniformly along its length. Finding ordering temperature by extrapolating the inverse susceptibility curve does not provide a correct T_C.

Edges And Diffractive Effects In Casimir Energies, Daniel N. Kabat, Dimitra Karabali, V P. Nair

Publications and Research

The prototypical Casimir effect arises when a scalar field is confined between parallel Dirichlet boundaries. We study corrections to this when the boundaries themselves have apertures and edges. We consider several geometries: a single plate with a slit in it, perpendicular plates separated by a gap, and two parallel plates, one of which has a long slit of large width, related to the case of one plate being semi-infinite. We develop a general formalism for studying such problems, based on the wavefunctional for the field in the gap between the plates. This formalism leads to a lower dimensional theory defined …

On The Casimir Interaction Between Holes In A Plate, Daniel N. Kabat, Dimitra Karabali, V P. Nair

Publications and Research

We study the leading long-distance attractive force between two holes in a plate arising from a scalar eld with Dirichlet boundary conditions on the plate. We use a formalism in which the interaction is governed by a non-local eld theory which lives on the two holes. The interaction energy is proportional to Q1Q2=r7 at large separation r, where Q1 and Q2 are certain charges associated with the holes. We compute these charges for round and rectangular holes. We show that the 1=r7 behavior is universal for separations large compared to the linear dimensions of the holes, irrespective of the spin …

Dynamical Decompactification And Three Large Dimensions, Brian Greene, Daniel N. Kabat, Stefanos Marnerides

Publications and Research

We study string gas dynamics in the early universe and seek to realize the Brandenberger - Vafa mechanism - a goal that has eluded earlier works - that singles out three or fewer spatial dimensions as the number which grow large cosmologically. Considering wound string interactions in an impact parameter picture, we show that a strong exponential suppression in the interaction rates for d > 3 spatial dimensions reflects the classical argument that string worldsheets generically intersect in at most four spacetime dimensions. This description is appropriate in the early universe if wound strings are heavy - wrapping long cycles - …

The Hamiltonian Approach To Yang-Mills (2 + 1): Expansion Scheme And Corrections To String Tension, Dimitra Karabali, V P. Nair, Alexandr Yelinkov

Publications and Research

We carry out further analysis of the Hamiltonian approach to Yang-Mills theory in 2+1 dimensions which helps to place the calculation of the vacuum wave function and the string tension in the context of a systematic expansion scheme. The solution of the Schrodinger equation is carried out recursively. The computation of correlators is re-expressed in terms of a two-dimensional chiral boson theory. The effective action for this theory is calculated to first order in our expansion scheme and to the fourth order in a kinematic expansion parameter. The resulting corrections to the string tension are shown to be very small, …

A Multivalent Dna Aptamer Specific For The B-Cell Receptor On Human Lymphoma And Leukemia, Prabodhika R. Mallikaratchy, Alessandro Ruggiero, Jeffrey R. Gardner, Vitaly Kuryavyi, William F. Maguire, Mark L. Heaney, Michael R. Mcdevitt, Dinshaw J. Patel, David A. Scheinberg

Publications and Research

Long-term survival still eludes most patients with leukemia and non-Hodgkin’s lymphoma. No approved therapies target the hallmark of the B cell, its mIgM, also known as the B-cell receptor (BCR). Aptamers are small oligonucleotides that can specifically bind to a wide range of target molecules and offer some advantages over antibodies as therapeutic agents. Here, we report the rational engineering of aptamer TD05 into multimeric forms reactive with the BCR that may be useful in biomedical applications. Systematic truncation of TD05 coupled with modification with locked nucleic acids (LNA) increased conformational stability and nuclease resistance. Trimeric and tetrameric versions with …

Trauma And The Representation Of The Unsayable In Late Twentieth-Century Fiction, Katina Rogers

Publications and Research

This dissertation explores the ways in which several fiction writers from France, the U.S., and Latin America experiment with the form of their works in writing about traumatic experience, as they navigate the tension between a propulsion toward expression and toward silence. Some of these traumas are vast, as in Edmond Jabès’ Le livre des questions (1963-1973), which addresses not only the Holocaust, but also questions of exile and identity. Others are on a smaller scale, such as Jacques Roubaud’s Quelque chose noir (1986), Julio Cortázar's Los autonautas de la cosmopista (1983), and Macedonio Fernández’s Museo de la Novela de …

Conceptualizing Hybridity: Deconstructing Boundaries Through The Hybrid, Haj Yazdiha

Publications and Research

History has shown that the notion of hybridity has existed far before it was popularized in postcolonial theory. However, in this time after imperialism, globalization has both expanded the reach of Western culture, and has allowed a process by which the West constantly interacts with the East. This hybridity is evident in every snapshot of society, from trends in "fusion" cuisine to the adoption of Caribbean rhythms in popular music. Ethnic Americans are marked with hyphenated identities: "Indian-American," "Asian-American," illuminating the lived experience of ties to a dominant culture coinciding with the cultural codes of a third world culture. This …

Becoming European? Constructing Identity In Urban Regeneration Discourse In Ireland, Alan Gerard Bourke

Publications and Research

Drawing upon policy documents and interview data, this article critically assesses how the conservation, interpretation and promotion of built heritage is used as a categorical identity referent within urban regeneration discourse in Ireland. The paper is critical of two inter-related dynamics. First, it addresses the relation between "culture-led" urban regeneration and the construction of a "sense of place." Second, it problematizes parallel attempts to constitute a sanitized and marketable urbanism expressed via a rhetorical and contrived veneer of European identity. A fundamental premise of the discussion is that the challenge of articulating a coherent and "distinctive" sense of urban cultural …
