Development Of A Mechanical Cavopulmonary Assist Device For The Failing Fontan Patients, Jugal Kapadia

Theses and Dissertations

The long term objective of this research is to develop a collapsible, percutaneously inserted, axial flow blood pump to improve blood flow in the cavopulmonary circulation. Through this research, the experimental evaluation of five blood pump prototypes and hemolysis testing of one blood pump prototype were performed. All prototypes demonstrated acceptable hydraulic performance. A comparison of the experimental results with numerical predictions demonstrated a 10-20% deviation, an acceptable range per industry standard. Hemolysis testing of a four bladed adult blood pump showed plasma free hemoglobin level of 20.04 mg/dL and maximum NIH (normalized index of hemolysis) level was 0.017 g/100L. …

Clones In Representable Matroids Over A Finite Field, Xiangqian Zhou

Combinatorics Seminar

A matroid is a pair (E,I) where E is a finite set and I is a collection of subsets of E that satisfies the following axioms: 1) I; 2) if I I and I I, then I mathcalI; 3) if I,J I and|I| < |J|, thenthereexists x J\I suchthatI {x} I. Two elements x and y of a matroid M are clones if the map that interchanges x and y and that fixes all other elements is an automorphism of M. It is clear that if E is the set of columns of a matrix over a field and I is the collection of subsets of E that are linearly independent, then (E,I) is a matroid. Such a matroid is essentially a sub-structure of the projective space over that field. We study clones in matroids that arise from matrices over a finite field. This is joint work with Reid, Robbins, and Wu.

Altruistic Task Allocation Despite Unbalanced Relationships Within Multi-Robot Communities, Ryan Morton, George A. Bekey, Christopher M. Clark

Computer Science and Software Engineering

Typical Multi-Robot Systems consist of robots cooperating to maximize global fitness functions. However, in some scenarios, the set of interacting robots may not share common goals and thus the concept of a global fitness function becomes invalid. This work examines Multi-Robot Communities(MRC), in which individual robots have independent goals. Within the MRC context, we present a task allocation architecture that optimizes individual robot fitness functions over long time horizons using reciprocal altruism.

Previous work has shown that reciprocating altruistic relationships can evolve between two willing robots, using market-based task auctions, while still protecting against selfish robots aiming to exploit …

Trophic Structure Of The Northwest Hawaiian Islands And Resident Monk Seals (Monachus Schaundslandi) During The Twentieth Century, Nina M. Thompson, Amy Hirons, Charles W. Potter, Charles Littnan

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The Hawaiian monk seal (Monachus schauinslandi) is an endangered species only found within the Hawaiian Archipelago. The majority of the breeding population for this seal is located around six islands in the Northwest Hawaiian Island chain (NWHI). Overall, both juvenile and adult seals have a wide range in δ¹³C and δ¹⁵N from 1912-2006 (δ¹³C: -12.5‰; δ¹⁵N: 12.6‰). Seals in the northern NWHI were enriched in δ¹³C by nearly 2‰ and depleted in δ¹⁵N by nearly 6‰ during the 96 years. Meanwhile, seals within the middle and …

Dust And The Type Ii-Plateau Supernova 2004et, R. Kotak, W. P. S. Meikle, D. Farrah, C. L. Gerardy, R. J. Foley, S. D. Van Dyk, C. Fransson, P. Lundqvist, J. Sollerman, R. Fesen

Dartmouth Scholarship

We present mid-infrared (MIR) observations of the Type II-plateau supernova (SN) 2004et, obtained with the Spitzer Space Telescope between 64 and 1406 days past explosion. Late-time optical spectra are also presented. For the period 300-795 days past explosion, we argue that the spectral energy distribution (SED) of SN 2004et comprises (1) a hot component due to emission from optically thick gas, as well as free-bound radiation; (2) a warm component due to newly formed, radioactively heated dust in the ejecta; and (3) a cold component due to an IR echo from the interstellar-medium dust of the host galaxy, NGC 6946. …

Stability And Error Estimates For Vector Field Interpolation And Decomposition On The Sphere With Rbfs, Edward J. Fuselier, Grady Wright

Mathematics Faculty Publications and Presentations

A new numerical technique based on radial basis functions (RBFs) is presented for fitting a vector field tangent to the sphere, S², from samples of the field at "scattered" locations on S². The method naturally provides a way to decompose the reconstructed field into its individual Helmholtz–Hodge components, i.e., into divergence-free and curl-free parts, which is useful in many applications from the atmospheric and oceanic sciences (e.g., in diagnosing the horizontal wind and ocean currents). Several approximation results for the method will be derived. In particular, Sobolevtype error estimates are obtained for both the interpolant and …

Observation Of Giant Positive Magnetoresistance In A Cooper Pair Insulator., H Q. Nguyen, Shawna M. Hollen, M D. Stewart Jr, J Shainline, Aijun Yin, J M. Xu, J M. Valles

Physics & Astronomy

Ultrathin amorphous Bi films, patterned with a nanohoneycomb array of holes, can exhibit an insulating phase with transport dominated by the incoherent motion of Cooper pairs (CP) of electrons between localized states. Here, we show that the magnetoresistance (MR) of this Cooper pair insulator (CPI) phase is positive and grows exponentially with decreasing temperature T, for T well below the pair formation temperature. It peaks at a field estimated to be sufficient to break the pairs and then decreases monotonically into a regime in which the film resistance assumes the T dependence appropriate for weakly localized single electron transport. We …

Beyond Biobricks: Synthesizing Synergistic Biochemical Systems From The Bottom-Up, Mark A. Bedau

Systems Science Friday Noon Seminar Series

Engineers who attempt to discover and optimize the behavior of complex biochemical systems face a dauntingly difficult task. This is especially true if the systems are governed by multiple qualitative and quantitative variables that have non-linear response functions and that interact synergistically. The synthetic biology community has responded to this difficulty by promoting the use of "standard biological parts" called "BioBricks", which are supposed to make biology into traditional engineering and enable engineers to "program living organisms in the same way a computer scientists can program a computer". But the BioBricks research program faces daunting hurdles, because the nonlinearity and …

Magnetoelastic Coupling Through The Antiferromagnet-To-Ferromagnet Transition Of Quasi-Two-Dimensional [Cu(Hf2)(Pyz)(2)]Bf4 Using Infrared Spectroscopy, J L. Musfeldt, L I. Vergara, T V. Brinzari, C Lee, L C. Tung, J Kang, Y J. Wang, J A. Schlueter, Jamie L. Manson, M H. Whangbo

Chemistry and Biochemistry Faculty Publications

We investigated magnetoelastic coupling through the field-driven transition to the fully polarized magnetic state in quasi-two-dimensional [Cu(HF2)(pyz)(2)]BF4 by magnetoinfrared spectroscopy. This transition modifies out-of-plane ring distortion and bending vibrational modes of the pyrazine ligand. The extent of these distortions increases with the field, systematically tracking the low-temperature magnetization. These distortions weaken the antiferromagnetic spin exchange, a finding that provides important insight into magnetic transitions in other copper halides.

On The Shell Of Some Graphs, William Staton

Combinatorics Seminar

Let G be a graph such that each vertex of G is contained in a (k + 1)clique for a positive integer k. We de ne the shell of G, denoted by Sh(G) as follows: The vertex set of Sh(G) consists of all distinct (k + 1)-cliques of G and two vertices in Sh(G) are adjacent if and only if the corresponding (k +1)-cliques have k vertices in common. If k = 1, Sh(G) will be the line graph of G. If G is a k-tree with at least k + 1 vertices, each vertex of G is contained in …

Reactivity And Distortions In The Self: Narcissism, Types Of Aggression, And The Functioning Of The Hypothalamic–Pituitary–Adrenal Axis During Early Adolescence, William M. Bukowski, Alex Schwartzman, Jonathan Bruce Santo, Catherine Bagwell, Ryan Adams

Psychology Faculty Publications

A multisample, multistudy project aimed at understanding how individual differences in narcissism during early adolescence are related to distortions in the aggression, and the reactivity of the hypothalamic–pituitary–adrenal axis to negative and positive experiences. The findings indicate that individual differences in narcissism are a remarkably stable aspect of personality during early adolescence. It is predictably related to an inflated view of the self that is not warranted by objective indices of social functioning. Further evidence shows that it promotes the continuity of aggressive behavior and is more strongly related to reactive aggression than to proactive aggression and more strongly related …

Leading Students To Investigate Diffusion As A Model Of Brine Shrimp Movement, Brynja R. Kohler, Rebecca J. Swank, James W. Haefner, James A. Powell

Mathematics and Statistics Faculty Publications

Integrating experimental biology laboratory exercises with mathematical modeling can be an effective tool to enhance mathematical relevance for biologists and to emphasize biological realism for mathematicians. This paper describes a lab project de-signed for and tested in an undergraduate biomathematics course. In the lab, students follow and track the paths of individual brine shrimp confined in shallow salt water in a Petri dish. Students investigate the question, “Is the movement well characterized as a 2-dimensional random walk?” Through open, but directed discussions, students derive the corresponding partial differential equation, gain an understanding of the solution behavior, and model brine shrimp …

Gravity Wave Ducting In The Upper Mesosphere And Lower Thermosphere Duct System, R. L. Walterscheid, Michael P. Hickey Ph.D.

Publications

We report on a numerical study of gravity wave propagation in a pair of ducts located in a region where dramatic changes in the airglow most likely associated with ducted wave trains are observed. We examine ducting in an upper mesosphere inversion (INV) and an always present lower thermosphere stable layer (LTD) for a range of phase speeds and horizontal wavelengths characteristic of ducting events. We analyze the propagation and modal structure of ducted waves for backgrounds with increasing realism, starting with a climatological temperature profile where only the LTD is present. In succession, we add the INV based on …

Western Suburban Literacy Initiative (WSLI) Conference

This workshop will show how mainstream teachers can make academic content more comprehensible to English Language Learners (ELL) without diluting the curriculum. More specifically, it will expose participants to strategies on how to keep ELL students at grade level while developing their English language proficiency. Participants will benefit from this session by: (i) developing greater fluency on how educators can help ELL succeed academically; and (ii) becoming better prepared to face the challenges of working in a diverse school.

Quasi-Least Squares With Mixed Linear Correlation Structures, Jichun Xie, Justine Shults, Jon Peet, Dwight Stambolian, Mary F. Cotch

UPenn Biostatistics Working Papers

Quasi-least squares (QLS) is a two-stage computational approach for estimation of the correlation parameters in the framework of generalized estimating equations (GEE). We prove two general results for the class of mixed linear correlation structures: namely, that the stage one QLS estimate of the correlation parameter always exists and is feasible (yields a positive definite estimated correlation matrix) for any correlation structure, while the stage two estimator exists and is unique (and therefore consistent) with probability one, for the class of mixed linear correlation structures. Our general results justify the implementation of QLS for particular members of the class of …

The Lambert W Function And Quantum Statistics, Sree Ram Valluri, M. Gil, D. J. Jeffrey, Shantanu Basu

Physics and Astronomy Publications

We present some applications of the Lambert W function (W function) to the formalism of quantum statistics (QS). We consider the problem of finding extrema in terms of energy for a general QS distribution, which involves the solution of a transcendental equation in terms of the W function. We then present some applications of this formula including Bose–Einstein systems in d dimensions, Maxwell–Boltzmann systems, and black body radiation. We also show that for the appropriate parameter values, this formula reduces to an analytic expression in connection with Wien’s displacement law that was found in a previous study. In addition, we …
