Modification And Improvement Of Empirical Liklihood For Missing Response Problem, Gary Chan

UW Biostatistics Working Paper Series

An empirical likelihood (EL) estimator was proposed by Qin and Zhang (2007) for a missing response problem under a missing at random assumption. They showed by simulation studies that the finite sample performance of EL estimator is better than some existing estimators. However, the empirical likelihood estimator does not have a uniformly smaller asymptotic variance than other estimators in general. We consider several modifications to the empirical likelihood estimator and show that the proposed estimator dominates the empirical likelihood estimator and several other existing estimators in terms of asymptotic efficiencies. The proposed estimator also attains the minimum asymptotic variance among …

Spatial Distribution Of Calcium-Gated Chloride Channels In Olfactory Cilia, Donald A. French, Dorjsuren Badamdorj, Steven J. Kleene

Mathematical Sciences Faculty Research

Background

In vertebrate olfactory receptor neurons, sensory cilia transduce odor stimuli into changes in neuronal membrane potential. The voltage changes are primarily caused by the sequential openings of two types of channel: a cyclic-nucleotide-gated (CNG) cationic channel and a calcium-gated chloride channel. In frog, the cilia are 25 to 200 µm in length, so the spatial distributions of the channels may be an important determinant of odor sensitivity.

Principal Findings

To determine the spatial distribution of the chloride channels, we recorded from single cilia as calcium was allowed to diffuse down the length of the cilium and activate the channels. …

Pseudomonas Aeruginosa Β-Lactamase Induction Requires Two Permeases, Ampg And Ampp, Kok-Fai Kong, Alian Aguila, Kalai Mathee, Lisa Schnepper

Department of Biological Sciences

Background

In Enterobacteriaceae, β-lactam antibiotic resistance involves murein recycling intermediates. Murein recycling is a complex process with discrete steps taking place in the periplasm and the cytoplasm. The AmpG permease is critical to this process as it transports N-acetylglucosamine anhydrous N-acetylmuramyl peptides across the inner membrane. In Pseudomonadaceae, this intrinsic mechanism remains to be elucidated. Since the mechanism involves two cellular compartments, the characterization of transporters is crucial to establish the link.

Results

Pseudomonas aeruginosa PAO1 has two ampG paralogs, PA4218 (ampP) and PA4393 (ampG). Topology analysis using β-galactosidase and alkaline phosphatase fusions indicates ampP and …

Next-To-Next-To-Leading Soft-Gluon Corrections For The Top Quark Cross Section And Transverse Momentum Distribution, Nikolaos Kidonakis

Faculty and Research Publications

I present results for top quark production in hadronic collisions at LHC and Tevatron energies. The soft-gluon corrections to the differential cross section are resummed at next-to-next-to-leading-logarithm accuracy via the two-loop soft anomalous dimension matrices. Approximate next-to-next-to-leading-order differential and total cross sections are calculated. Detailed theoretical predictions are shown for the t (t) over bar cross section and the top quark p(T) distribution at the Tevatron and the LHC.

Conclusions About Niche Expansion In Introduced Impatiens Walleriana Populations Depend On Method Of Analysis, Lisa Mandle, Dan L. Warren, Matthias H. Hoffman, A. Townsend Peterson, Johanna Schmitt, Eric J. Von Wettberg

Department of Biological Sciences

Determining the degree to which climate niches are conserved across plant species’ native and introduced ranges is valuable to developing successful strategies to limit the introduction and spread of invasive plants, and also has important ecological and evolutionary implications. Here, we test whether climate niches differ between native and introduced populations of Impatiens walleriana, globally one of the most popular horticultural species. We use approaches based on both raw climate data associated with occurrence points and ecological niche models (ENMs) developed with Maxent. We include comparisons of climate niche breadth in both geographic and environmental spaces, taking into account differences …

Spatial And Temporal Melt Variability At Helheim Glacier, East Greenland, And Its Effect On Ice Dynamics, M. L. Andersen, T. B. Larsen, M. Nettles, P. Elosegui, D. Van As, Gordon S. Hamilton, Leigh A. Stearns, J. L. Davis, A. P. Ahlstrøm, J. De Juan, G. Ekström, L. Stenseng, S. A. Khan, R. Forsberg, D. Dahl-Jensen

Earth Science Faculty Scholarship

Understanding the behavior of large outlet glaciers draining the Greenland Ice Sheet is critical for assessing the impact of climate change on sea level rise. The flow of marine-terminating outlet glaciers is partly governed by calving-related processes taking place at the terminus but is also influenced by the drainage of surface runoff to the bed through moulins, cracks, and other pathways. To investigate the extent of the latter effect, we develop a distributed surface-energy-balance model for Helheim Glacier, East Greenland, to calculate surface melt and thereby estimate runoff. The model is driven by data from an automatic weather station operated …

Comparative Study Of Field Enhancement Between Isolated And Coupled Metal Nanoparticles: An Analytical Approach, Greg Sun, Jacob B. Khurgin

Physics Faculty Publications

We present an analytical model that takes into account the coupling between the surface plasmon modes in complex metal nanostructures. We apply this model to evaluate the field enhancement in the gap of two coupled Au metal spheres embedded in GaN dielectric and compare the result with that obtained by the single sphere. The results show additional improvement can be obtained in the gap depending on the width of the gap. This approach offers a clear physical insight for the enhancement and a straightforward method for optimization.

Using Off-Diagonal Confinement As A Cooling Method, V. G. Rousseau, K. Hettiarachchilage, M. Jarrell, J. Moreno, D. E. Sheehy

Faculty Publications

In a recent letter we proposed a new confining method for ultracold atoms on optical lattices, which is based on off-diagonal confinement (ODC). This method was shown to have distinct advantages over the conventional diagonal confinement (DC), which makes use of a trapping potential, such as the existence of pure Mott phases and highly populated condensates. In this manuscript we show that the ODC method can also lead to lower temperatures than the DC method for a wide range of control parameters. Using exact diagonalization we determine this range of parameters for the hard-core case and then we extend our …

One Love: Explicit Monogamy Agreements Among Heterosexual Young Adult Couples At Increased Risk Of Sexually Transmitted Infections, Jocelyn T. Warren, S M. Harvey, Christopher R. Agnew

Department of Psychological Sciences Faculty Publications

HIV prevention strategies among couples include condom use, mutual monogamy, and HIV testing. Research suggests that condom use is more likely with new or casual partners, and tends to decline as relationships become steady over time. Little is known, however, about explicit mutual monogamy agreements and HIV testing within heterosexual couples. This study used data from 434 young heterosexual couples at increased risk of HIV and sexually transmitted infections (STIs) to assess (a) couple concordance on perceptions of a monogamy agreement, sustained monogamy, and HIV testing; and (b) the associations of relationship and demographic factors with monogamy agreement, sustained monogamy, …

Design Concepts Of Terahertz Quantum Cascade Lasers: Proposal For Terahertz Laser Efficiency Improvements, Tillmann Kubis, Saumitra Raj Mehrotra, Gerhard Klimeck

Birck and NCN Publications

Conceptual disadvantages of typical resonant phonon terahertz quantum cascade lasers 􏰎THz-QCLs􏰍 are analyzed. Alternative designs and their combination within a concrete device proposal are discussed to improve the QCL performance. The improvements are 􏰎1􏰍 indirect pumping of the upper laser level, 􏰎2􏰍 diagonal optical transitions, 􏰎3􏰍 complete electron thermalization, and 􏰎4􏰍 materials with low effective electron masses. The nonequilibrium Green’s function method is applied to predict stationary electron transport and optical gain. The proposed THz-QCL shows a higher optical gain, a lower threshold current, and a higher operation temperature. Alloy disorder scattering can worsen the QCL performance.

Biphasic Targeting And Cleavage Furrow Ingression Directed By The Tail Of A Myosin Ii, X. Fang, J. Y. Luo, R. Nishihama, C. Wloka, C. Dravis, M. Travaglia, M. Iwase, Elizabeth Ann Vallen, E. Bi

Biology Faculty Works

Cytokinesis in animal and fungal cells utilizes a contractile actomyosin ring (AMR). However, how myosin II is targeted to the division site and promotes AMR assembly, and how the AMR coordinates with membrane trafficking during cytokinesis, remains poorly understood. Here we show that Myo1 is a two-headed myosin II in Saccharomyces cerevisiae, and that Myo1 localizes to the division site via two distinct targeting signals in its tail that act sequentially during the cell cycle. Before cytokinesis, Myo1 localization depends on the septin-binding protein Bni5. During cytokinesis, Myo1 localization depends on the IQGAP Iqg1. We also show that the Myo1 …

A Multifactorial Mechanism In The Superior Antimalarial Activity Of Α-C-Galcer, John Schmieg, Guangli Yang, Richard W. Franck, Moriya Tsuji

Publications and Research

We have previously shown that the C-glycoside analog of α-galactosylceramide (α-GalCer), α-C-GalCer, displays a superior inhibitory activity against the liver stages of the rodent malaria parasite Plasmodium yoelii than its parental glycolipid, α-GalCer. In this study, we demonstrate that NK cells, as well as IL-12, are a key contributor for the superior activity displayed by α-C-GalCer. Surprisingly, the diminished production of Th2 cytokines, including IL-4, by α-C-GalCer has no affect on its superior therapeutic activity relative to α-GalCer. Finally, we show that the in vivo administration of α-C-GalCer induces prolonged maturation of dendritic cells (DCs), as well as an enhanced …
