Unitary Representations And Theta Correspondence For Type I Classical Groups, Hongyu He

Faculty Publications

In this paper, we discuss the positivity of the Hermitian form (,)π introduced by Li in Invent. Math. 27 (1989) 237-255. Let (G1, G2) be a type I dual pair with G1 the smaller group. Let π be an irreducible unitary representation in the semistable range of θ(MG1, MG2) (see Communications in Contemporary Mathematics, Vol. 2, 2000, pp. 255-283). We prove that the invariant Hermitian form (,)π is positive semidefinite under certain restrictions on the size of G2 and a mild growth condition on the matrix coefficients of π. Therefore, if (,)π does not vanish, θ(MG1, MG2) (π) is unitary. …

Bacillus Anthracis Virulence In Guinea Pigs Vaccinated With Anthrax Vaccine Adsorbed Is Linked To Plasmid Quantities And Clonality, Pamala R. Coker, Kimothy L. Smith, Patricia F. Fellows, Galena Rybachuck, Konstantin G. Kousoulas, Martin E. Hugh-Jones

Faculty Publications

Bacillus anthracis is a bacterial pathogen of great importance, both historically and in the present. This study presents data collected from several investigations and indicates that B. anthracis virulence is associated with the clonality and virulence of plasmids pXO1 and pXO2. Guinea pigs vaccinated with Anthrax Vaccine Adsorbed were challenged with 20 B. anthracis isolates representative of worldwide genetic diversity. These same isolates were characterized with respect to plasmid copy number by using a novel method of quantitative PCR developed for rapid and efficient detection of B. anthracis from environmental samples. We found that the copy numbers for both pXO1 …

The Betti Numbers Of Some Finite Racks, R. A. Litherland, Sam Nelson

Faculty Publications

We show that the lower bounds for Betti numbers given in (J. Pure Appl. Algebra 157 (2001) 135) are equalities for a class of racks that includes dihedral and Alexander racks. We confirm a conjecture from the same paper by defining a splitting for the short exact sequence of quandle chain complexes. We define isomorphisms between Alexander racks of certain forms, and we also list the second and third homology groups of some dihedral and Alexander quandles. © 2002 Elsevier Science B.V.

Bioengineered ‘Golden’ Indica Rice Cultivars With Β-Carotene Metabolism In The Endosperm With Hygromycin And Mannose Selection Systems, Karabi Datta, Niranjan Baisakh, Norman Oliva, Lina Torrizo, Editha Abrigo, Jing Tan, Mayank Rai, Sayda Rehana, Salim Al-Babili, Peter Beyer, Ingo Potrykus, Swapan K. Datta

Faculty Publications

Vitamin-A deficiency (VAD) is a major malnutrition problem in South Asia, where indica rice is the staple food. Indica-type rice varieties feed more than 2 billion people. Hence, we introduced a combination of transgenes using the biolistic system of transformation enabling biosynthesis of provitamin A in the endosperm of several indica rice cultivars adapted to diverse ecosystems of different countries. The rice seed-specific glutelin promoter (Gt-1 P) was used to drive the expression of phytoene synthase (psy), while lycopene β-cyclase (lcy) and phytoene desaturase (crtI), fused to the transit peptide sequence of the pea-Rubisco small subunit, were driven by the …

Carboxylate Groups On The Manganese-Stabilizing Protein Are Required For Efficient Binding Of The 24 Kda Extrinsic Protein To Photosystem Ii, Terry M. Bricker, Laurie K. Frankel

Faculty Publications

The effects of the modification of carboxylate groups on the manganese-stabilizing protein on the binding of the 24 kDa extrinsic protein to Photosystem II were investigated. Carboxylate groups on the manganese-stabilizing protein were modified with glycine methyl ester in a reaction facilitated by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide. The manganese-stabilizing protein which was modified while associated with NaCl-washed membranes could bind to calcium chloride-washed PS II membranes and reconstitute oxygen evolution in a manner similar to that observed for unmodified manganese-stabilizing protein (Frankel, L,K, Cruz, J. C. and Bricker, T. M. (1999) Biochemistry 38, 14271-14278), However, PS II membranes reconstituted with this modified protein …

Revised Analysis Of The Supersoft X-Ray Phase, Helium Enrichment, And Turnoff Time In The 2000 Outburst Of The Recurrent Nova Ci Aquilae, Izumi Hachisu, Mariko Kato, Bradley E. Schaefer

Faculty Publications

Recurrent nova CI Aquilae entered the final decline phase a bit before 2001 May, about 300 days after the optical maximum, showing the slowest evolution among recurrent novae. Based on the optically thick wind mass-loss theory of the thermonuclear runaway model, we have estimated the turnoff time of the CI Aql 2000 outburst to be in late 2001 March, after a luminous supersoft X-ray source phase lasting ∼150 days (from 2000 November until 2001 March). We have also found, by fitting our theoretical light curves with the 1917 and 2000 outbursts, the white dwarf (WD) mass to be MWD = …

Nonlinear Equations And Wavelets, A. Ludu, R. F. O'Connell, J. P. Draayer

Faculty Publications

Wavelet-inspired approaches for localized solutions of nonlinear partial differential equations (NDPE) were presented. A multi-scale similarity analysis was used which gives specific relations between the velocity, amplitude and width of localized solutions of nonlinear differential equations. This approach does not need the explicit form of the exact solutions.

A Meta-Analysis Of Genome-Wide Linkage Scans For Hypertension: The National Heart, Lung And Blood Institute Family Blood Pressure Program, Michael A. Province, Sharon L.R. Kardia, Koustubh Ranade, Dabeeru C. Rao, Bonnie A. Thiel, Richard S. Cooper, Neil Risch, Stephen T. Turner, David R. Cox, Steven C. Hunt, Alan B. Weder, Eric Boerwinkle

Faculty Publications

Background: Four multicenter Networks (GenNet, GENOA, HyperGEN, SAPPHIRe) form the National Heart, Lung and Blood Institute Family Blood Pressure Program (FBPP), to search for hypertension/blood pressure (BP) genes. The networks used different family designs and targeted multiple ethnic groups, using standardized protocols and definitions. Linkage genome scans were done on samples within each network (N = 6245 relatives). Methods: The evidence was synthesized using meta-analysis. Results: Combining ethnic groups, no region reached LOD >2, but several small peaks were identified, including chromosome 2p where two other recent reports find hypertension linkage. Conclusions: No regions show uniformly large effects on BP/hypertension …

Formation And Character Of An Ancient 19-M Ice Cover And Underlying Trapped Brine In An "Ice-Sealed" East Antarctic Lake, Peter T. Doran, Christian H. Fritsen, Christopher P. Mckay, John C. Priscu, Edward E. Adams

Faculty Publications

Lake Vida, one of the largest lakes in the McMurdo Dry Valleys of Antarctica, was previously believed to be shallow (<10 >m) and frozen to its bed year-round. New ice-core analysis and temperature data show that beneath 19 m of ice is a water column composed of a NaCl brine with a salinity seven times that of seawater that remains liquid below - 10°C. The ice cover thickens at both its base and surface, sealing concentrated brine beneath. The ice cover is stabilized by a negative feedback between ice growth and the freezing-point depression of the brine. The ice cover …

A Genome-Wide Scan For Body Mass Index Among Nigerian Families, Adebowale Adeyemo, Amy Luke, Richard Cooper, Xiaodong Wu, Bamidele Tayo, Xiaofeng Zhu, Charles Rotimi, Nourdine Bouzekri, Ryk Ward

Faculty Publications

Objective: Interest in mapping genetic variants that are associated with obesity remains high because of the increasing prevalence of obesity and its complications worldwide. Data on genetic determinants of obesity in African populations are rare. Research Methods and Procedures: We have undertaken a genome-wide scan for body mass index (BMI) in 182 Nigerian families that included 769 individuals. Results: The prevalence of obesity was only 5%, yet polygenic heritability for BMI was in the expected range (0.46 ± 0.07). Tandem repeat markers (402) were typed across the genome with an average map density of 9 cM. Pedigree-based analysis using a …

A Representation Theorem For Recovering Contraction Relations Satisfying Wci, Zhaohui Zhu, Bin Li, Xi'an Xiao, Shifu Chen, Wujia Zhu

Faculty Publications

A notion of an image structure associated with the canonical epistemic state is introduced. Based on it, we get a representation result for recovering contraction inference relations satisfying the condition weak conjunctive inclusion (wci) in terms of F-standard epistemic AGM states. In effect, this result establishes a representation theorem for belief contraction functions satisfying AGM postulates (k-1) - (k-7), and Rott's (wci) and (k-8c), and hence generalizes Rott's corresponding result in the finite framework. © 2002 Elsevier Science B.V.

Deterrents To Participation In Parenting Education, Debora C. Johnson, Betty C. Harrison, Michael F. Burnett, Peter Emerson

Faculty Publications

The purpose of this study was to determine the deterrents to participation by adults in parenting education programs. The objectives were (a) to describe parents with children in selected day care facilities on selected sociodemographic characteristics, (b) to determine factors that deterred those parents from participating in parenting education, and (c) to determine if there was a relationship between selected sociodemographic characteristics and the parents' participation in parenting education programs. A simple random sample of parents was drawn from the accessible population. Factor analysis revealed five factors that deterred this population from participating in parenting education: Lack of Confidence, Lack …

Multiplicative Renormalization And Generating Functions I, Nobuhiro Asai, Izumi Kubo, Hui Hsiung Kuo

Faculty Publications

Let μ be a probability measure on the real line with finite moments of all orders. Apply the Gram-Schmidt orthogonalization process to the system {1, x, x2, . . ., xn, . . .} to get orthogonal polynomials Pn(x), n ≥ 0, which have leading coefficient 1 and satisfy (x-αn)Pn(x) = Pn+1(x) +ωnPn-1(x). In general it is almost impossible to use this process to compute the explicit form of these polynomials. In this paper we use the multiplicative renormalization to develop a new method for deriving generating functions for a large class of probability measures. From a generating function for …

Optimization Of Resonances In Photonic Crystal Slabs, Robert P. Lipton, Stephen P. Shipman, Stephanos Venakides

Faculty Publications

Variational methods are applied to the design of a two-dimensional lossless photonic crystal slab to optimize resonant scattering phenomena. The method is based on varying properties of the transmission coefficient that are connected to resonant behavior. Numerical studies are based on boundary-integral methods for crystals consisting of multiple scatterers. We present an example in which we modify a photonic crystal consisting of an array of dielectric rods in air so that a weak transmission anomaly is transformed into a sharp resonance.
