Exploration Of Distributional Models For A Novel Intensity-Dependent Normalization , Nicola Lama, Patrizia Boracchi, Elia Mario Biganzoli

COBRA Preprint Series

Currently used gene intensity-dependent normalization methods, based on regression smoothing techniques, usually approach the two problems of location bias detrending and data re-scaling without taking into account the censoring characteristic of certain gene expressions produced by experiment measurement constraints or by previous normalization steps. Moreover, the bias vs variance balance control of normalization procedures is not often discussed but left to the user's experience. Here an approximate maximum likelihood procedure to fit a model smoothing the dependences of log-fold gene expression differences on average gene intensities is presented. Central tendency and scaling factor were modeled by means of B-splines smoothing …

Physics

Measurements of the production of forward π0 mesons from p+p and d+Au collisions at √sNN=200  GeV are reported. The p+p yield generally agrees with next-to-leading order perturbative QCD calculations. The d+Au yield per binary collision is suppressed as η increases, decreasing to ∼30% of the p+p yield at ⟨η⟩=4.00, well below shadowing expectations. Exploratory measurements of azimuthal correlations of the forward π0 with charged hadrons at η≈0 show a recoil peak in p+p that is suppressed in d+Au at low pion energy. These observations are qualitatively consistent with a saturation picture of the low-x gluon structure of heavy nuclei.

Physics

Transverse momentum spectra of π±, p, and ¯p up to 12  GeV/c at midrapidity in centrality selected Au+Au collisions at √sNN=200  GeV are presented. In central Au+Au collisions, both π± and p(¯p) show significant suppression with respect to binary scaling at pT≳4  GeV/c. Protons and antiprotons are less suppressed than π±, in the range 1.5≲pT≲6  GeV/c. The π−/π+ and ¯p/p ratios show at most a weak pT dependence and no significant centrality dependence. The p/π ratios in central Au+Au collisions approach the values in p+p and d+Au collisions at pT≳5  GeV/c. The results at high pT indicate that the partonic …

Quantifying Fluid Mixing With The Shannon Entropy, Marco Camesasca, Miron Kaufman, Ica Manas Zloczower

Physics Faculty Publications

We introduce a methodology to quantify the quality of mixing in various systems, including polymeric ones, by adapting the Shannon information entropy. For illustrative purposes we use particle advection of two species in a two-dimensional cavity flow. We compute the entropy by using the probability of finding a suitable chosen group/complex of particles of a given species, at a given location. By choosing the size of the group to be in direct proportion to the overall concentration of the components in the mixture we ensure that the entropic measure is maximized for the case of perfect mixing, that is, when …

Scaling The Zachman Framework A Software Development Methodology For Non-Enterprise Applications, Carla L. Thompson

Regis University Student Publications (comprehensive collection)

The software development methodology brought forth in John Zachman's System Architecture Framework can be used to design a wide range of information systems. While the Zachman Framework is very robust and typically used for developing large scale Enterprise Applications, this project will demonstrate that the framework can easily be scaled to fit a small scale non-Enterprise Application. The Zachman Framework is a six by six matrix that breaks down system requirements into cells that document the system. Each row of the Zachman Framework will be examined to determine if the documentation would be needed. A discussion about the appropriateness of …

Generalized Entanglement As A Natural Framework For Exploring Quantum Chaos, Y. S. Weinstein, L Viola

Dartmouth Scholarship

We demonstrate that generalized entanglement (Barnum et al., Phys. Rev. A, 68 (2003) 032308) provides a natural and reliable indicator of quantum chaotic behavior. Since generalized entanglement depends directly on a choice of preferred observables, exploring how generalized entanglement increases under dynamical evolution is possible without invoking an auxiliary coupled system or decomposing the system into arbitrary subsystems. We find that, in the chaotic regime, the long-time saturation value of generalized entanglement agrees with random matrix theory predictions. For our system, we provide physical intuition into generalized entanglement within a single system by invoking the notion of extent …

Twisted Supersymmetric Sigma Model On The Lattice, Simon Catterall, Sofiane Ghadab

Physics - All Scholarship

In this paper we conduct a numerical study of the supersymmetric O(3) non-linear sigma model. The lattice formulation we employ was derived in \cite{sigma1} and corresponds to a discretization of a {\it twisted} form of the continuum action. The twisting process exposes a {\it nilpotent} supercharge Q and allows the action to be rewritten in Q-exact form. These properties may be maintained on the lattice. We show how to deform the theory by the addition of potential terms which preserve the supersymmetry. A Wilson mass operator may be introduced in this way with a minimal breaking of supersymmetry. We additionally …

A technique, and associated system and computer executable program code on a computer readable storage medium, for automatically correcting distortion of a front-projected display under observation by at least one camera. The technique may be employed in a myriad of front-projected display environments, e.g., single or multiple projectors and cameras are used. The technique includes: observing a first image, projected from at least one projector, comprising at least one target distribution of light intensities; for each conglomeration of white pixels of a difference image, compute a bounding box comprising a corresponding conglomeration of pixels in a framebuffer information of the …

Location-Based Services And The Privacy-Security Dichotomy, Katina Michael, L. Perusco, M G. Michael

Faculty of Informatics - Papers (Archive)

Location-based services (LBS) rely on knowledge of a user’s location to provide tailored services or information by means of a wireless device. LBS applications have wide-ranging implications for society, particularly in the context of tracking and monitoring groups of individuals such as children, invalids, and parolees. Despite a great deal of attention paid to technical and commercial aspects of LBS technologies, consideration of the legal, ethical, social and technology momentum issues involved has been wanting. This paper examines some of the more pressing issues that are expected to arise from the widespread use of LBS. The outcome of this paper …

Detection Of Diffuse Interstellar [O Ii] Emission From The Milky Way Using Spatial Heterodyne Spectroscopy, E. J. Mierkiewicz, R. J. Reynolds, F. L. Roesler, J. M. Harlander, K. P. Jaehnig

Physical Sciences - Daytona Beach

Using a newly developed spatial heterodyne spectrometer (SHS), we have obtained the first radial velocity resolved emission-line profiles of diffuse [O II] 3726 and 3729 angstrom emission lines from the warm (10,000 K) ionized component of our Galaxy's interstellar medium. These [O II] lines are a principal coolant for this widespread, photoionized gas and are a potential tracer of variations in the gas temperature resulting from unidentified heating processes that appear to be acting within the Galaxy's disk and halo. By spectrally isolating for the first time Galactic [O II] from atmospheric [O II] emission, we were able to detect …

Agenda: Celebrating The Centennial Of The Antiquities Act, University Of Colorado Boulder. Natural Resources Law Center, University Of Colorado Boulder. Center Of The American West

Celebrating the Centennial of the Antiquities Act (October 9)

For 100 years, the Antiquities Act has been used by nearly every President in the 20th century to set aside and protect lands threatened with privatization and development. The list of lands first protected under the Antiquities Act – and that might never have been protected without it – is truly remarkable. Many of our most treasured national parks including the Grand Canyon, Olympic, Zion, Arches, Glacier Bay, and Acadia, began as national monuments. All told, Presidents have issued 123 proclamations setting aside millions of acres of land under the Antiquities Act.

Enhanced Convergence And Robust Performance Of Randomized Dynamical Decoupling, Lea F. Santos, Lorenza Viola

Dartmouth Scholarship

We demonstrate the advantages of randomization in coherent quantum dynamical control. For systems which are either time-varying or require decoupling cycles involving a large number of operations, we find that simple randomized protocols offer superior convergence and stability as compared to deterministic counterparts. In addition, we show how randomization may allow us to outperform purely deterministic schemes at long times, including combinatorial and concatenated methods. General criteria for optimally interpolating between deterministic and stochastic design are proposed and illustrated in explicit decoupling scenarios relevant to quantum information storage.

Efficient Support For Application-Specific Video Adaptation, Jie Huang

Dissertations and Theses

As video applications become more diverse, video must be adapted in different ways to meet the requirements of different applications when there are insufficient resources. In this dissertation, we address two sorts of requirements that cannot be addressed by existing video adaptation technologies: (i) accommodating large variations in resolution and (ii) collecting video effectively in a multi-hop sensor network. In addition, we also address requirements for implementing video adaptation in a sensor network.

Accommodating large variation in resolution is required by the existence of display devices with widely disparate screen sizes. Existing resolution adaptation technologies usually aim at adapting video …

Odd-Even Effects In Bent-Core Compounds Containing Terminal N-Alkyl Carboxylate Groups, S. Umadevi, Antal Jakli, B. Sadashiva

Antal Jakli

A homologous series of eleven five-ring symmetrical bent-core compounds containing terminal n-alkyl carboxylate groups were synthesized, characterized and their dielectric and electro-optical properties have been investigated. The lower homologues (n = 6-11) of the series show B-2 structures with an interesting odd-even effect concerning their local director tilt and polar arrangements. This odd-even effect probably is due to steric (entropic) reasons, which are not suppressed by the relatively low polar interaction. Three of the middle homologues display a B-7' phase, which is bistable and shows linear electro-optical switching with a transition to the chiral antiferroelectric smectic phase at a lower …

Targeted Maximum Likelihood Learning, Mark J. Van Der Laan, Daniel Rubin

U.C. Berkeley Division of Biostatistics Working Paper Series

Suppose one observes a sample of independent and identically distributed observations from a particular data generating distribution. Suppose that one has available an estimate of the density of the data generating distribution such as a maximum likelihood estimator according to a given or data adaptively selected model. Suppose that one is concerned with estimation of a particular pathwise differentiable Euclidean parameter. A substitution estimator evaluating the parameter of the density estimator is typically too biased and might not even converge at the parametric rate: that is, the density estimator was targeted to be a good estimator of the density and …

Detection Of PrpCwd In Postmortem Rectal Lymphoid Tissues In Rocky Mountain Elk (Cervus Elaphus Nelsoni) Infected With Chronic Wasting Disease, Terry R. Spraker, Thomas L. Gidlewski, Aru Balachandran, Kurt C.. Vercauteren, Lynn Creekmore, Randy D. Munger

United States Department of Agriculture Wildlife Services: Staff Publications

Preclinical diagnostic tests for transmissible spongiform encephalopathies have been described for mule deer (Odocoileus hemionus), using biopsy tissues of palatine tonsil, and for sheep, using lymphoid tissues from palatine tonsil, third eyelid, and rectal mucosa. The utility of examining the rectal mucosal lymphoid tissues to detect chronic wasting disease (CWD) was investigated in Rocky Mountain elk (Cervus elaphus nelsoni), a species for which there is not a live-animal diagnostic test. Postmortem rectal mucosal sections were examined from 308 elk from two privately owned herds that were depopulated. The results of the postmortem rectal mucosal sections were …

Breakup Of Air Bubbles In Water: Memory And Breakdown Of Cylindrical Symmetry, Nathan C. Keim, Peder Møller, Wendy W. Zhang, Sidney R. Nagel

Physics

Using high-speed video, we have studied air bubbles detaching from an underwater nozzle. As a bubble distorts, it forms a thin neck which develops a singular shape as it pinches off. As in other singularities, the minimum neck radius scales with the time until the breakup. However, because the air-water interfacial tension does not drive the breakup, even small initial cylindrical asymmetries are preserved throughout the collapse. This novel, nonuniversal singularity retains a memory of the nozzle shape, size, and tilt angle. In the last stages, the air appears to tear instead of pinch.

The Zeta Function Of A Hypergraph, Christopher K. Storm

Dartmouth Scholarship

We generalize the Ihara-Selberg zeta function to hypergraphs in a natural way. Hashimoto's factorization results for biregular bipartite graphs apply, leading to exact factorizations. For $(d,r)$-regular hypergraphs, we show that a modified Riemann hypothesis is true if and only if the hypergraph is Ramanujan in the sense of Winnie Li and Patrick Solé. Finally, we give an example to show how the generalized zeta function can be applied to graphs to distinguish non-isomorphic graphs with the same Ihara-Selberg zeta function.

Microfabrication And Evaluation Of Planar Thin-Film Microfluidic Devices, Bridget Ann Peeni

Theses and Dissertations

Over the past 15 years, research in the field of microfluidics has rapidly gained popularity. By seeking to miniaturize and automate separation-based analysis, microfluidic research seeks to improve current methods through decreased cost, analysis time, and sources of contamination. My work has focused on developing a novel fabrication method, based on standard microfabrication techniques, to create thin-film microfluidic devices. This microfabrication format makes it possible to generate devices that provide high efficiencies, enable mass fabrication, and provide a platform capable of integrating the microfluidic and electronic components necessary for a micro-total analysis system (μ-TAS). Device fabrication combines the processes of …
