A Network Biology Approach to Denitrification in Pseudomonas aeruginosa
(20150223)Pseudomonas aeruginosa is a metabolically flexible member of the Gammaproteobacteria. Under anaerobic conditions and the presence of nitrate, P. aeruginosa can perform (complete) denitrification, a respiratory process of ... 
a new method of surfaceresistance measurement with a niobium triaxial cavity working at 2K
(AIP Publishing, 199307)A 1.5GHz superconducting niobium triaxial cavity has been fabricated to study residual surface resistance of superconducting materials at 2 K. Unlike many other structures where the entire test samples have to be placed ... 
A New Population of Highz, Dusty Lyα Emitters and Blobs Discovered by WISE: Feedback Caught in the Act?
(IOP PUBLISHING LTD, 201306)By combining data from the NASA Widefield Infrared Survey Explorer (WISE) mission with optical spectroscopy from the W. M. Keck telescope, we discover a midIR color criterion that yields a 78% success rate in identifying ... 
a note on the general likelihood measure of overlap
(Ecological Society of America, 1984) 
A note on the iteration of the Chandrasekhar nonlinear Hequation
(AIP Publishing, 197904)An iteration scheme to solve the Chandrasekhar H equation in the form H (_) ={1___F_ 1 0[_ (s) H (s)]/(s +_) d s}_1 is shown to converge monotonically and uniformly. 
A note on the switching adiabatic theorem
(AIP Publishing, 201210)We derive a nearly optimal upper bound on the running time in the adiabatic theorem for a switching family of Hamiltonians. We assume the switching Hamiltonian is in the Gevrey class G(alpha) as a function of time, and we ... 
a numerical study of periodic disturbances on twolayer Couette flaw
(AIP Publishing, 199812)The flow of two viscous liquids is investigated numerically with a volume of fluid scheme. The scheme incorporates a semiimplicit Stokes solver to enable computations at low Reynolds numbers, and a secondorder velocity ... 
a population of z > 2 farinfrared herschelspireselected starbursts
(IOP Publishing Ltd., 201212)We present spectroscopic observations for a sample of 36 HerschelSpire 250500 mu m selected galaxies (HSGs) at 2 < z < 5 from the Herschel Multitiered Extragalactic Survey. Redshifts are confirmed as part of a large ... 
a precision test for an extra spatial dimension using blackholepulsar binaries
(IOP Publishing Ltd., 201108)We discuss the observable effects of enhanced black hole mass loss in a black holeneutron star (BHNS) binary, due to the presence of a warped extra spatial dimension of curvature radius L in the braneworld scenario. For ... 
a redshift survey of herschel farinfrared selected starbursts and implications for obscured star formation
(IOP Publishing Ltd., 201212)We present Keck spectroscopic observations and redshifts for a sample of 767 HerschelSPIRE selected galaxies (HSGs) at 250, 350, and 500 mu m, taken with the Keck I Low Resolution Imaging Spectrometer and the Keck II DEep ... 
A regularized GaussNewton trust region approach to imaging in diffuse optical tomography
(Siam Publications, 2011)We present a new algorithm for the solution of nonlinear least squares problems arising from parameterized imaging problems with diffuse optical tomographic data [D. Boas et al., IEEE Signal Process. Mag., 18 (2001), pp. ... 
A Series of Supramolecular Complexes for Solar Energy Conversion via Water Reduction to Produce Hydrogen: An Excited State Kinetic Analysis of Ru(II),Rh(III),Ru(II) Photoinitiated Electron Collectors
(MDPI, 20111227)Mixedmetal supramolecular complexes have been designed that photochemically absorb solar light, undergo photoinitiated electron collection and reduce water to produce hydrogen fuel using low energy visible light. This ... 
A simple model of circadian rhythms based on dimerization and proteolysis of PER and TIM
(CELL PRESS, 199911)Many organisms display rhythms of physiology and behavior that are entrained to the 24h cycle of light and darkness prevailing on Earth. Under constant conditions of illumination and temperature, these internal biological ... 
A state space error estimate for poddeim nonlinear model reduction
(Siam Publications, 2012)This paper derives state space error bounds for the solutions of reduced systems constructed using proper orthogonal decomposition (POD) together with the discrete empirical interpolation method (DEIM) recently developed ... 
A uniqueness result for pMonotone viscosity solutions of HamiltonJacobi equations in bounded domains
(Siam Publications, 2009)We consider a class of HamiltonJacobi equations H(x, Du(x))  0 with no udependence and with continuity properties consistent with recent applications in queueing theory. Continuous viscosity solutions are considered in ... 
A volumeoffluid formulation for the study of coflowing fluids governed by the HeleShaw equations
(American Institute of Physics, 201308)We present a computational framework to address the flow of two immiscible viscous liquids which coflow into a shallow rectangular container at one side, and flow out into a holding container at the opposite side. Assumptions ... 
A Water Maser Flare in W49N: Amplification by a Rotating Foreground Cloud
(IOP PUBLISHING LTD, 199812)We monitored the 22 GHz H2O maser emission toward W49N from December 1989 through May 1990. During this period we observed an outburst in a component at 66.25 km s(1). The flux density of the flaring component increased ...
