Modification And Improvement Of Empirical Likelihood For Missing Response Problem, Kwun Chuen 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. …

Valproic acid is an anticonvulsant drug that works by increasing the levels of γ-aminobutyric acid (GABA). Determination of valproic acid is quite difficult because it has no chromophore groups in its structure. Aa analytical method using gas chromatography (GC) with flame ionization detector for the determination of valproic acid in human plasma has been developed and optimized. Valproic acid was extracted from plasma by liquid-liquid extraction method using diethyl ether. The optimum analysis conditions for valproic acid in plasma were achieved by regulated gas chromatography injector and detector at a temperature of 250oC and temperature programming with an initial temperature …

Chitosan is a natural cationic polymer. That cationic property makes chitosan can form polyelectrolite complex (PEC) with anionic polymer. In this research, pectin was used as anionic polymer that interact ionically with chitosan. The aim of this research is to produce and characterize chitosan-pectin PEC that would be used as matrix in floating tablet. The solutions of chitosan and pectin 0,3% w/v were mixed in ratio 1:9, 3:7, 1:1, 7:3 and 9:1 with pH of the solution 4,5 and 5,0. The best condition to produce PEC was in pH 5,0 with ratio of chitosan and pectin = 3:7. The differences …

Theophylline is a bronchodilator used for the treatment of bronchial asthma and other respiratory diseases. Theophylline has a narrow therapeutic index (10-20 µg/ml) and relatively short elimination half-life (6,19 ± 0,031 hours). Causes rapid elimination rate of theophylline should be given periodically to maintain drug levels in blood for the desired therapeutic effect can be achieved. The preparation of theophylline controlled release is expected to produce blood concentrations of theophylline in a more stable.

Measurements Of The Electric Form Factor Of The Neutron Up To Q(2)=3.4 Gev2 Using The Reaction (3)(He)Over-Right-Arrowe((E)Over-Right-Arrow, E ' N)Pp, S. Riordan, Timothy Holmstrom

Chemistry & Physics Faculty Publications

The electric form factor of the neutron was determined from studies of the reaction ³He⃗(e⃗,e^′n)pp in quasielastic kinematics in Hall A at Jefferson Lab. Longitudinally polarized electrons were scattered off a polarized target in which the nuclear polarization was oriented perpendicular to the momentum transfer. The scattered electrons were detected in a magnetic spectrometer in coincidence with neutrons that were registered in a large-solid-angle detector. More than doubling the Q² range over which it is known, we find G_Eⁿ=0.0236±0.0017(stat)±0.0026(syst), 0.0208±0.0024±0.0019, and 0.0147±0.0020±0.0014 for Q²=1.72, 2.48, and 3.41  GeV², respectively.

Time-Varying Harmonic Analyzer Prototype, Diego F. Fabri, Carlos H. N. Martins, Leandro R. M. Silva, Carlos A. Duque

University Faculty Publications and Creative Works

This paper presents a time-varying harmonic analyzer based on the Sliding Window DFT implemented on a DSP platform. The harmonic decomposition is carried out using the TMS320F28027 digital signal processor, and the samples of the decomposed signal are sent to a PC based computer using serial interface. Several real cases are analyzed, revealing the time-varying behavior of the harmonic component. Different from commercial harmonic analyzer, the prototype presented in this paper uses a different way to visualize the harmonic components, based on time decomposition approach. This new visualization of time-varying harmonics might help engineers and researchers to develop new insights …

Jack - Height Adjustable Office Desk Mechanism, John Walsh

Other

This mechanism was developed out of the increasing requirement for individual users to be able to adjust the height of their desk to an ergonomically correct position for their physicality. Sitting at a standard height desk (usually 720-740mm) for long durations has been linked to health problems, including back and posture problems and DVT, for those who fall either side of the average user in terms of anthropometric height range. A typical problem with "systems furniture" which is widely installed in most corporate open-plan offices is that components are "shared" for cost, functionality and aesthetic purposes. Typically, this means that …

A comprehensive seafloor biomass and abundance database has been constructed from 24 oceanographic institutions worldwide within the Census of Marine Life (CoML) field projects. The machine-learning algorithm, Random Forests, was employed to model and predict seafloor standing stocks from surface primary production, water-column integrated and export particulate organic matter (POM), seafloor relief, and bottom water properties. The predictive models explain 63% to 88% of stock variance among the major size groups. Individual and composite maps of predicted global seafloor biomass and abundance are generated for bacteria, meiofauna, macrofauna, and megafauna (invertebrates and fishes). Patterns of benthic standing stocks were positive …

Upsilon(1s)->Gamma+F2'(1525); F2'(1525)->K0sk0s Decays, Raymond Mountain, Marina Artuso, S. Blusk, T. Skwarnicki

Physics - All Scholarship

We report on a study of exclusive radiative decays of the Upsilon(1S) resonance into a final state consisting of a photon and two K0s candidates. We find evidence for a signal for Upsilon(1S)->gamma f_2'(1525); f_2'(1525)->K0sK0s, at a rate (4.0+/-1.3+/-0.6)x10^{-5}, consistent with previous observations of Upsilon(1S)->gamma f_2'(1525); f_2'(1525)->K+K-, and isospin. Combining this branching fraction with existing branching fraction measurements of Upsilon(1S)->gamma f_2'(1525) and J/psi->gamma f_2'(1525), we obtain the ratio of branching fractions: B(Upsilon(1S)->gamma f_2'(1525))/B(J/psi->gamma f_2'(1525))=0.09+/-0.02, approximately consistent with expectations based on soft collinear effective theory.

The research problem focused on the low speed levels of fencers during the final stages of matches, prompting the researcher to develop speed endurance through match-like interval training exercises over nine weeks to assess their effects on motor and physical abilities in fencers aged 18 to 20. Twelve fencers, representing all three fencing weapons, were divided into two equal groups based on pre-test results of speed endurance. A series of tests measured relevant motor and physical skills before and after the training program. The data was statistically analyzed, leading to discussions, conclusions, and recommendations. Notably, all participants achieved first place …
