Bohr Density Of Simple Linear Group Orbits, Roger Howe, François Ziegler

François Ziegler

We show that any non-zero orbit under a non-compact, simple, irreducible linear group is dense in the Bohr compactification of the ambient space.

Fiscal Decentralization And China’S Regional Infant Mortality, Gregory J. Brock, Yinghua Jin, Tong Zeng

Gregory J. Brock

Regional Chinese infant mortality rates (IMRs) are examined using a stochastic frontier method for the first time. The composite error term method yields estimates of large underreporting of IMRs over time and provinces in China during the past 30 years. China does not follow the standard growth paradigm of moregrowth leading to lower IMRs. Fiscal decentralization has not alleviated the problem of high IMRs. Both IMRs and the sex ratio at birth suggest reported data constitute a floor or minimal level of demographic distress across provinces with millions of missing females not fully included in the data. China’s one-child policy …

Cohen Factorizations: Weak Functoriality And Applications, Saeed Nasseh, Sean Sather-Wagstaff

Saeed Nasseh

We investigate Cohen factorizations of local ring homomorphisms from three perspectives. First, we prove a “weak functoriality” result for Cohen factorizations: certain morphisms of local ring homomorphisms induce morphisms of Cohen factorizations. Second, we use Cohen factorizations to study the properties of local ring homomorphisms (Gorenstein, Cohen–Macaulay, etc.) in certain commutative diagrams. Third, we use Cohen factorizations to investigate the structure of quasi-deformations of local rings, with an eye on the question of the behavior of CI-dimension in short exact sequences.

Primary Spaces, Mackey’S Obstruction, And The Generalized Barycentric Decomposition, Patrick Iglesias-Zemmour, François Ziegler

François Ziegler

We call a hamiltonian N-space primary if its moment map is onto a single coadjoint orbit. The question has long been open whether such spaces always split as (homogeneous) × (trivial), as an analogy with representation theory might suggest. For instance, Souriau’s barycentric decomposition theorem asserts just this when N is a Heisenberg group. For general N, we give explicit examples which do not split, and show instead that primary spaces are always flat bundles over the coadjoint orbit. This provides the missing piece for a full “Mackey theory” of hamiltonian G-spaces, where G is an overgroup in which N …

Accelerated Resolution Therapy For Treatment Of Pain Secondary To Symptoms Of Combat-Related Posttraumatic Stress Disorder, Kevin E. Kip, Laney Rosenzweig, Diego F. Hernandez, Amy Shuman, David M. Diamond, Sue Ann Girling, Kelly L. Sullivan, Trudy R. Wittenberg, Ann M. Witt, Cecile A. Lengacher, Brian Anderson, Susan C. Mcmillan

Kelly L. Sullivan

Background: As many as 70% of veterans with chronic pain treated within the US Veterans Administration (VA) system may have posttraumatic stress disorder (PTSD), and conversely, up to 80% of those with PTSD may have pain. We describe pain experienced by US service members and veterans with symptoms of PTSD, and report on the effect of Accelerated Resolution Therapy (ART), a new, brief exposure-based therapy, on acute pain reduction secondary to treatment of symptoms of PTSD.
Methods: A randomized controlled trial of ART versus an attention control (AC) regimen was conducted among 45 US service members/veterans with symptoms of combat-related …

Generalizations Of The Inverse Weibull And Related Distributions With Applications, Broderick O. Oluyede, Tao Yang

Broderick O. Oluyede

In this paper, the generalized inverse Weibull distribution including the exponentiated or proportional reverse hazard and Kumaraswamy generalized inverse Weibull distributionsare presented. Properties of these distributions including the behavior of the hazard and reverse hazard functions, moments, coefficients of variation, skewness, andkurtosis, entropy, Fisher information matrix are studied. Estimates of the model parameters via method of maximum likelihood (ML), and method of moments (MOM) are presented for complete and censored data. Numerical examples are also presented.

Localized Quantum States, François Ziegler

François Ziegler

Let X be a symplectic manifold and Aut(L) the automorphism group of a Kostant-Souriau line bundle on X. *Quantum states for X*, as defined by J.-M. Souriau in the 1990s, are certain positive-definite functions on Aut(L) or, less ambitiously, on any "large enough" subgroup G of Aut(L). This definition has two major drawbacks: when G=Aut(L) there are no known examples; and when G is a Lie subgroup the notion is, as we shall see, far from selective enough. In this paper we introduce the concept of a quantum state *localized at Y*, where Y is a coadjoint orbit of a …

Multiscale Geometric Modeling Of Macromolecules I: Cartesian Representation, Kelin Xia, Xin Feng, Zhan Chen, Yiying Tong, Guo-Wei Wei

Zhan Chen

This paper focuses on the geometric modeling and computational algorithm development of biomolecular structures from two data sources: Protein Data Bank (PDB) and Electron Microscopy Data Bank (EMDB) in the Eulerian (or Cartesian) representation. Molecular surface (MS) contains non-smooth geometric singularities, such as cusps, tips and self-intersecting facets, which often lead to computational instabilities in molecular simulations, and violate the physical principle of surface free energy minimization. Variational multiscale surface definitions are proposed based on geometric flows and solvation analysis of biomolecular systems. Our approach leads to geometric and potential driven Laplace–Beltrami flows for biomolecular surface evolution and formation. The …

Matrices From Vegetable Oils, Cashew Nut Shell Liquid, And Other Relevant Systems For Biocomposite Applications, Rafael L. Quirino, Thomas F. Garrison, Michael R. Kessler

Rafael L. Quirino

The partial replacement of petroleum-derived plastics and composites by novel bio-based materials from inexpensive, renewable, natural resources has the potential to greatly impact the plastics, coatings, and composites industries. Natural starting materials are usually abundant and renewable on a time scale many orders of magnitude smaller than petroleum. These characteristics, in combination with good mechanical properties, make the design of bio-based composites an interesting strategy for lowering the environmental impact of the plastics and composites industries while maintaining economical competitiveness. The present review will focus on the progress made over the last decade in the development of a select group …

A Two Years Longitudinal Study Of A Transgenic Huntington Disease Monkey, Anthony W. S. Chan, Yan Xu, Jie Jiang, Tayeb Rahim, Jannet Kocerha, Dongming Zhao, Tim Chi, Heidi Engelhardt, Sean Moran, Katherine Larkin, Adam Neumann, Haiying Cheng, Chunxia Li, Katie Nelson, Heather Banta, Stuart M. Zola, Francois Villinger, Jinjing Yang, Claudia M. Testa, Hui Mao, Xiaodong Zhang, Jocelyne Bachevalier

Jannet Kocerha

Background: A two-year longitudinal study composed of morphometric MRI measures and cognitive behavioral evaluation was performed on a transgenic Huntington’s disease (HD) monkey. rHD1, a transgenic HD monkey expressing exon 1 of the human gene encoding huntingtin (HTT) with 29 CAG repeats regulated by a human polyubiquitin C promoter was used together with four age-matched wild-type control monkeys. This is the first study on a primate model of human HD based on longitudinal clinical measurements.

Results: Changes in striatal and hippocampal volumes in rHD1 were observed with progressive impairment in motor functions and cognitive decline, including deficits in learning stimulus-reward …

La Visión Del Indígena En El Resplandor De Mauricio Magdaleno: Discurso Nacionalista Y Fracaso Revolucionario., Dolores Rangel

Dolores Rangel

El resplandor (1937) de Mauricio Magdaleno es una obra que aborda la problemática del indígena en el marco del México posrevolucionario, vista desde la perspectiva del indígena y en oposición al mundo del blanco. La obra refleja el sentimiento de desilusión y fracaso de los ideales revolucionarios ante el estado de cosas imperante. En la visión de Magdaleno, el indio es el sujeto que ha sido maltratado históricamente, que ha sufrido los embates de la revolución, pero que no llega a recibir los beneficios de ésta. La condición de abuso por parte del mestizo y particularmente del funcionario público, se …

Treatment Of Neurodegenerative Ataxias With Intravenous Immune Globulin, Theresa A. Zesiewicz, Seok Hun Kim, Kelly L. Sullivan, Jeannie Stephenson, Israt Jahan, Susan L. Perlman, Jessica D. Shaw, Tuan Vu, Clifton L. Gooch

Kelly L. Sullivan

Background: Neurodegenerative ataxias, including spinocerebellar ataxias (SCAs), are progressive diseases without effective treatment. There is preclinical evidence that inflammation may contribute to neuronal injury in several neurodegenerative ataxias. Intravenous immune globulin (IVIG) is a therapeutic modality that is used as treatment of several autoimmune and inflammatory disorders.
Methods: The primary objective of this open-label pilot study was to assess the effect of IVIG on neurodegenerative ataxias as measured by total scale for the assessment and rating of ataxia (SARA) score. Three patients received IVIG (2 g/kg of body weight, divided over 5 days) once monthly for 3 months, and were …

Premorbid Personality And The Risk Of Parkinson's Disease, Kelly L. Sullivan, James A. Mortimer, Wei Wang, Theresa A. Zesiewicz, James H. Brownlee Jr., Amy R. Borenstein

Kelly L. Sullivan

Background: Previous studies support the hypothesis that premorbid personality characteristics may be associated with the risk of Parkinson’s disease (PD). However, most of these relied upon subjective reports of premorbid personality earlier in life, which may be subject to recall bias. The objective of the current study was to evaluate the association of PD with risk-taking, routinization, smoking and alcohol consumption in early-adult life as indicators of premorbid personality.
Methods: In-person interviews were conducted with 89 PD patients and 99 controls from a university-based medical center. Associations between indicators of early-adult personality and risk of PD were examined using logistic …

Lung Flute Improves Symptoms And Health Status In Copd With Chronic Bronchitis: A 26 Week Randomized Controlled Trial, Sanjay Sethi, Jingjing Yin, Pamela K. Anderson

Background: Chronic obstructive pulmonary disease (COPD) is characterized by mucus hypersecretion that contributes to disease related morbidity and is associated with increased mortality. The Lung Flute® is a new respiratory device that produces a low frequency acoustic wave with moderately vigorous exhalation to increase mucus clearance. We hypothesized that the Lung Flute, used on a twice daily basis will provide clinical benefit to patients with COPD with chronic bronchitis.

Methods: We performed a 26 week randomized, non-intervention controlled, single center, open label trial in 69 patients with COPD and Chronic Bronchitis. The primary endpoint was change in respiratory …

The Nature Of Project Success, Michael J. Cuellar

Michael J. Cuellar

This paper investigates the ontological status of project success. The literature shows that success has historically been considered to be an objective property of a project, one that can be assessed and the status of the project as a success or failure determined. However, this approach is shown to have serious deficiencies in dealing with certain project results. As an alternative, this paper suggests that following the subjective view of project success; success should be considered as a politically determined social construction. The paper advocates using Archer’s Morphogenetic Social Theory (Archer 1995; Cuellar 2010b) to explanatory mechanism. Under that theory, …

Numerical Studies Of The Generalized L1 Greedy Algorithm For Sparse Signals, Fangjun Arroyo, Edward Arroyo, Xiezhang Li, Jiehua Zhu

Xiezhang Li

The generalized l1 greedy algorithm was recently introduced and used to reconstruct medical images in computerized tomography in the compressed sensing framework via total variation minimization. Experimental results showed that this algorithm is superior to the reweighted l1-minimization and l1 greedy algorithms in reconstructing these medical images. In this paper the effectiveness of the generalized l1 greedy algorithm in finding random sparse signals from underdetermined linear systems is investigated. A series of numerical experiments demonstrate that the generalized l1 greedy algorithm is superior to the reweighted l1-minimization and l1 greedy algorithms in the successful recovery of randomly generated Gaussian sparse …

Modeling The Effect Of Water, Sanitation, And Hygiene And Oral Cholera Vaccine Implementation In Haiti, Isaac Chun-Hai Fung, David L. Fitter, Rebekah H. Borse, Martin I. Meltzer, Jordan W. Tappero

Isaac Chun-Hai Fung

In 2010, toxigenic Vibrio cholerae was newly introduced to Haiti. Because resources are limited, decisionmakers need to understand the effect of different preventive interventions. We built a static model to estimate the potential number of cholera cases averted through improvements in coverage in water, sanitation and hygiene (WASH) (i.e., latrines, point-of-use chlorination, and piped water), oral cholera vaccine (OCV), or a combination of both. We allowed indirect effects and non-linear relationships between effect and population coverage. Because there are limited incidence data for endemic cholera in Haiti, we estimated the incidence of cholera over 20 years in Haiti by using …

Symplectic Harmonic Theory And The Federer-Fleming Deformation Theorem, Yi Lin

Yi Lin

In this article, we initiate a geometric measure theoretic approach to symplectic Hodge theory. In particular, we apply one of the central results in geometric measure theory, the Federer-Fleming deformation theorem, together with the cohomology theory of normal cur- rents on a differential manifold, to establish a fundamental property on symplectic Harmonic forms. We show that on a closed symplectic manifold, every real primitive cohomology class of positive degrees admits a symplectic Harmonic representative not supported on the entire mani- fold. As an application, we use it to investigate the support of symplectic Harmonic representatives of Thom classes, and give …

Discrete Fourier Restriction Associated With Kdv Equations, Yi Hu, Xiaochun Li

Yi Hu

In this paper, we consider a discrete restriction associated with KdV equations. Some new Strichartz estimates are obtained. We also establish the local well-posedness for the periodic generalized Korteweg-de Vries equation with nonlinear term $F(u)\p_x u$ provided F∈C5 and the initial data ϕ∈Hs with s>1/2.

Longitudinal Transcriptomic Dysregulation In The Peripheral Blood Of Transgenic Huntington’S Disease Monkeys, Jannet Kocerha, Yuhong Liu, David Willoughby, Kumaravel Chidamparam, Joseph Benito, Kate Nelson, Yan Xu, Tim Chi, Heidi Engelhardt, Sean Moran, Shang-Hsun Yang, Shi-Hua Li, Xiao-Jiang Li, Katherine Larkin, Adam Neumann, Heather Banta, Jinjing Yang, Anthony W. S. Chan

Jannet Kocerha

Background: Huntington’s Disease (HD) is a progressive neurodegenerative disorder caused by an expansion in the polyglutamine (polyQ) region of the Huntingtin (HTT) gene. The clinical features of HD are characterized by cognitive, psychological, and motor deficits. Molecular instability, a core component in neurological disease progression, can be comprehensively evaluated through longitudinal transcriptomic profiling. Development of animal models amenable to longitudinal examination enables distinct disease-associated mechanisms to be identified.

Results: Here we report the first longitudinal study of transgenic monkeys with genomic integration of various lengths of the human HTT gene and a range of polyQ repeats. With this unique group …

Single-Step Electrochemical Functionalization Of Double-Walled Carbon Nanotube (Dwcnt) Membranes And The Demonstration Of Ionic Rectification, Xin Zhan, Ji Wu, Zhiqiang Chen, Bruce J. Hinds

Ji Wu

Carbon nanotube (CNT) membranes allow the mimicking of natural ion channels for applications in drug delivery and chemical separation. Double-walled carbon nanotube membranes were simply functionalized with dye in a single step instead of the previous two-step functionalization. Non-faradic electrochemical impedance spectra indicated that the functionalized gatekeeper by single-step modification can be actuated to mimic the protein channel under bias. This functional chemistry was proven by a highly efficient ion rectification, wherein the highest experimental rectification factor of ferricyanide was up to 14.4. One-step functionalization by electrooxidation of amine provides a simple and promising functionalization chemistry for the application of …
