A Polynomial Invariant for Flat Virtual Links
Louis H. Kauffman, R. Bruce Richter
This paper gives a polynomial invariant for flat virtual links. In the case of one component, the polynomial specializes to Turaev's virtual string polynomial. We show that Turaev'…
System size and centrality dependence of charged hadron transverse momentum spectra in Au+Au and Cu+Cu collisions at sqrt(s) = 62.4 and 200 GeV
B. Alver
We present transverse momentum distributions of charged hadrons produced in Cu+Cu collisions at sqrt(s) = 62.4 and 200 GeV. The spectra are measured for transverse momenta of 0.25…
M-regularity and the Fourier-Mukai transform
Giuseppe Pareschi, Mihnea Popa
This is a survey of M-regularity for coherent sheaves on abelian varieties and its applications, based on lectures given by the second author at the Seattle conference, in August 2…
On Atkin and Swinnerton-Dyer Congruence Relations (2)
A. O. L. Atkin, Wen-Ching Winnie Li, Ling Long
In this paper we give an example of a noncongruence subgroup whose three-dimensional space of cusp forms of weight 3 has the following properties. For each of the four residue clas…
The Isomorphism Problem for Toral Relatively Hyperbolic Groups
Francois Dahmani, Daniel Groves
We provide a solution to the isomorphism problem for torsion-free relatively hyperbolic groups with abelian parabolics. As special cases we recover solutions to the isomorphism pro…
On the minimum number of colors for knots
Louis H. Kauffman, Pedro Lopes
In this article we take up the calculation of the minimum number of colors needed to produce a non-trivial coloring of a knot. This is a knot invariant and we use the torus knots o…
Nanoscale Suppression of Magnetization at Atomically Assembled Manganite Interfaces
J. J. Kavich, M. P. Warusawithana, J. W. Freeland +4
Using polarized X-rays, we compare the electronic and magnetic properties of a La(2/3)Sr(1/3)MnO(3)(LSMO)/SrTiO(3)(STO) and a modified LSMO/LaMnO(3)(LMO)/STO interface. Using the t…
Measurement of the Isolated Photon Cross Section in p-pbar Collisions at sqrt{s}=1.96 TeV
D0 Collaboration
The cross section for the inclusive production of isolated photons has been measured in p anti-p collisions at sqrt{s}=1.96 TeV with the D0 detector at the Fermilab Tevatron Collid…
Neutralino annihilation beyond leading order
Vernon Barger, Wai-Yee Keung, Heather E. Logan +2
High-precision measurements of the relic dark matter density and the calculation of dark matter annihilation branching fractions in the sun or the galactic halo today motivate the…
Strangelet Search in AuAu Collisions at 200 GeV
STAR Collaboration
We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at $\sNN = 200 $GeV near beam rapidities at the STAR detector. We have sensit…
Energy dependence of directed flow over a wide range of pseudorapidity in Au+Au collisions at RHIC
B. B. Back
We report on measurements of directed flow as a function of pseudorapidity in Au+Au collisions at energies of 19.6, 62.4, 130 and 200 GeV as measured by the PH…
Cones of closed alternating walks and trails
Amitava Bhattacharya, Uri N. Peled, Murali K. Srinivasan
Consider a graph whose edges have been colored red and blue. Assign a nonnegative real weight to every edge so that at every vertex, the sum of the weights of the incident red edge…
Ab Initio Structural Energetics of Beta-Si3N4 Surfaces
Juan C. Idrobo, Hakim Iddir, Serdar Ogut +3
Motivated by recent electron microscopy studies on the Si3N4/rare-earth oxide interfaces, the atomic and electronic structures of bare beta-Si3N4 surfaces are investigated from fir…

Hakim Iddir, Vladimir Skavysh, Serdar Ogut +1
The characterization of Pt/TiO2 (Degussa P25) catalyst system using atomic resolution Z-contrast images and electron energy loss spectroscopy in the scanning transmission electron…
An Algorithm for Missing Value Estimation for DNA Microarray Data
Shmuel Friedland, Mostafa Kaveh, Amir Niknejad +1
Gene expression data matrices often contain missing expression values. In this paper, we describe a new algorithm, named improved fixed rank approximation algorithm (IFRAA), for mi…
Fast Monte-Carlo Low Rank Approximations for Matrices
Shmuel Friedland, Mostafa Kaveh, Amir Niknejad +1
In many applications, it is of interest to approximate data, given by mxn matrix A, by a matrix B of at most rank k, which is much smaller than m and n. The best approximation is g…

Laura Ghezzi, Huy Tai Ha, Olga Kashcheyeva
Let k be an algebraically closed field of characteristic 0 and let K*/K be a finite extension of algebraic function fields of transcendence degree 2 over k. Let v* be a k-valuation…

The charged-particle pseudorapidity density for Au+Au collisions at sqrt(s_NN)=62.4 GeV has been measured over a wide range of impact parameters and compared to results obtained at…
Algorithmic and Complexity Results for Decompositions of Biological Networks into Monotone Subsystems
Bhaskar DasGupta, German Andres Enciso, Eduardo Sontag +1
A useful approach to the mathematical analysis of large-scale biological networks is based upon their decompositions into monotone dynamical systems. This paper deals with two comp…
The unstable spectrum of the Navier-Stokes operator in the limit of vanishing viscosity
