Topological Atomic Displacements, Kirchhoff and Wiener Indices of Molecules
Ernesto Estrada, Naomichi Hatano
We provide a physical interpretation of the Kirchhoff index of any molecules as well as of the Wiener index of acyclic ones. For the purpose, we use a local vertex invariant that i…
A Vibrational Approach to Node Centrality and Vulnerability in Complex Networks
Ernesto Estrada, Naomichi Hatano
We propose a new measure of vulnerability of a node in a complex network. The measure is based on the analogy in which the nodes of the network are represented by balls and the lin…
Automatic Detection of Limb Prominences in 304 A EUV Images
Nicolas Labrosse, Silvia Dalla, Steve Marshall
A new algorithm for automatic detection of prominences on the solar limb in 304 A EUV images is presented, and results of its application to SOHO/EIT data discussed. The detection…
Revised Results for Non-thermal Recombination Flare Hard X-Ray Emission
J. C. Brown, P. C. V. Mallik, N. R. Badnell
Brown and Mallik (BM) recently showed that, for hot sources, recombination of non-thermal electrons (NTR) onto highly ionised heavy ions is not negligible compared to non-thermal b…
Two-stream instability in quasi-one-dimensional Bose-Einstein condensates
H. Terças, J. T. Mendonça, G. R. M. Robb
We apply a kinetic model to predict the existence of an instability mechanism in elongated Bose-Einstein condensates. Our kinetic description, based on the Wigner formalism, is emp…
Folksonomic Tag Clouds as an Aid to Content Indexing
Morgan Harvey, Mark Baillie, Ian Ruthven +1
Social tagging systems have recently developed as a popular method of data organisation on the Internet. These systems allow users to organise their content in a way that makes sen…
Ancilla-Driven Universal Quantum Computation
Janet Anders, Daniel K. L. Oi, Elham Kashefi +2
We propose a method of manipulating a quantum register remotely with the help of a single ancilla that steers the evolution of the register. The fully controlled ancilla qubit is c…
A remark on Schatten-von Neumann properties of resolvent differences of generalized Robin Laplacians on bounded domains
Jussi Behrndt, Matthias Langer, Igor Lobanov +2
In this note we investigate the asymptotic behaviour of the -numbers of the resolvent difference of two generalized self-adjoint, maximal dissipative or maximal accumulative Rob…
Quantum System Identification by Bayesian Analysis of Noisy Data: Beyond Hamiltonian Tomography
S. G. Schirmer, D. K. L. Oi
We consider how to characterize the dynamics of a quantum system from a restricted set of initial states and measurements using Bayesian analysis. Previous work has shown that Hami…
Rate of escape and central limit theorem for the supercritical Lamperti problem
Mikhail V. Menshikov, Andrew R. Wade
The study of discrete-time stochastic processes on the half-line with mean drift at given by as is known as Lamperti's problem. We give sharp alm…
Spatial interference from well-separated condensates
M. E. Zawadzki, P. F. Griffin, E. Riis +1
We use magnetic levitation and a variable-separation dual optical plug to obtain clear spatial interference between two condensates axially separated by up to 0.25 mm -- the larges…
Enhanced frequency up-conversion in Rb vapor
A. Vernier, S. Franke-Arnold, E. Riis +1
We demonstrate highly efficient generation of coherent 420nm light via up-conversion of near-infrared lasers in a hot rubidium vapor cell. By optimizing pump polarizations and freq…
An Upper Limit on the Stochastic Gravitational-Wave Background of Cosmological Origin
The LIGO Scientific Collaboration, the Virgo Collaboration
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmologica…
Radiative transition rates and collision strengths for Si II
M. A. Bautista, P. Quinet, P. Palmeri +3
Aims. This work reports radiative transition rates and electron impact excitation collision strengths for levels of the 3s23p, 3s3p2, 3s24s, and 3s23d configurations of Siii. Metho…
Laser-driven plasma waves in capillary tubes
F. Wojda, K. Cassou, G. Genoud +11
The excitation of plasma waves over a length of up to 8 centimeters is, for the first time, demon- strated using laser guiding of intense laser pulses through hydrogen filled glass…
Deriving the Coronal Hole Electron Temperature: Electron Density Dependent Ionization/Recombination Considerations
J. G. Doyle, S. Chapman, P. Bryans +4
Comparison of appropriate theoretical derived line ratios with observational data can yield estimates of a plasma's physical parameters, such as electron density or temperature. Th…
Polarization properties in the transition from below to above lasing threshold in broad-area vertical-cavity surface-emitting lasers
M. Schulz-Ruhtenberg, I. V. Babushkin, N. A. Loiko +2
For highly divergent emission of broad-area vertical-cavity surface-emitting lasers (VCSELs) a rotation of the polarization direction by up to 90 degrees occurs when the pump rate…
Accuracy analysis of high-order lattice Boltzmann models for rarefied gas flows
Jianping Meng, Yonghao Zhang
In this work, we have theoretically analyzed and numerically evaluated the accuracy of high-order lattice Boltzmann (LB) models for capturing non-equilibrium effects in rarefied ga…
Modeling the Longitudinal Asymmetry in Sunspot Emergence -- the Role of the Wilson Depression
Fraser Watson, Lyndsay Fletcher, Silvia Dalla +1
The distributions of sunspot longitude at first appearance and at disappearance display an east-west asymmetry that results from a reduction in visibility as one moves from disk ce…

The LIGO Scientific Collaboration, The Virgo Collaboration, B. P. Abbott +678
We present a search for gravitational waves from 116 known millisecond and young pulsars using data from the fifth science run of the LIGO detectors. For this search ephemerides ov…
Longitudinal wave-breaking limits in a unified geometric model of relativistic warm plasmas
