Semi-Quantum Key Distribution
Michel Boyer, Ran Gelles, Dan Kenigsberg +1
Secure key distribution among two remote parties is impossible when both are classical, unless some unproven (and arguably unrealistic) computation-complexity assumptions are made,…
The MiMeS Project: First Results
J. H. Grunhut, E. Alecian, D. A. Bohlender +11
Massive stars are those stars with initial masses above about 8 times that of the sun, eventually leading to catastrophic explosions in the form of supernovae. These represent the…
Simultaneous estimation of attenuation and structure parameters of aggregated red blood cells from backscatter measurements
Emilie Franceschini, François T. H. Yu, Guy Cloutier
The analysis of the ultrasonic frequency-dependent backscatter coefficient of aggregating red blood cells reveals information about blood structural properties. The difficulty to a…
Shocks and finite-time singularities in Hele-Shaw flow
Seung-Yeop Lee, Razvan Teodorescu, Paul Wiegmann
Hele-Shaw flow at vanishing surface tension is ill-defined. In finite time, the flow develops cusp-like singularities. We show that the ill-defined problem admits a weak {\it dispe…
MOST photometry of the enigmatic PMS pulsator HD 142666
K. Zwintz, T. Kallinger, D. B. Guenther +11
We present precise photometry of the pulsating Herbig Ae star HD 142666 obtained in two consecutive years with the MOST (Microvariability & Oscilations of STars) satellite. Previou…
The convex hull of a regular set of integer vectors is polyhedral and effectively computable
Alain Finkel, Jérôme Leroux
Number Decision Diagrams (NDD) provide a natural finite symbolic representation for regular set of integer vectors encoded as strings of digit vectors (least or most significant di…
Density of rational points on diagonal quartic surfaces
Adam Logan, David McKinnon, Ronald van Luijk
Let a,b,c,d be nonzero rational numbers whose product is a square, and let V be the diagonal quartic surface in PP^3 defined by ax^4+by^4+cz^4+dw^4=0. We prove that if V contains a…
Monochromatic plane-fronted waves in conformal gravity are pure gauge
Luca Fabbri, M. B. Paranjape
We consider plane-fronted, monochromatic gravitational waves on a Minkowski background, in a conformally invariant theory of general relativity. By this we mean waves of the form:…
Diagnoses to unravel secular hydrodynamical processes in rotating main sequence stars
T. Decressin, S. Mathis, A. Palacios +4
(Abridged) We present a detailed analysis of the main physical processes responsible for the transport of angular momentum and chemical species in the radiative regions of rotating…
Hirota's virtual multi-soliton solutions of N=2 supersymmetric Korteweg-de Vries equations
Arthemy V. Kiselev, Veronique Hussin
We prove that Mathieu's N=2 supersymmetric Korteweg-de Vries equations with a=1 or a=4 admit Hirota's n-supersoliton solutions, whose nonlinear interaction does not produce any pha…
Super Earth Explorer: A Coronagraphic Off-Axis Space Telescope
J. Schneider, A. Boccaletti, D. Mawet +12
The Super-Earth Explorer is an Off-Axis Space Telescope (SEE-COAST) designed for high contrast imaging. Its scientific objective is to make the physico-chemical characterization of…
Approaches to Open Access in Scientific Publishing
J. Harnad
Approaches to scientific journal publishing that provide free access to all readers are challenging the standard subscription-based model. But in domains that have a well-functioni…
Properties of WNh stars in the Small Magellanic Cloud: evidence for homogeneous evolution
F. Martins, D. J. Hillier, J. C. Bouret +4
We derive the physical properties of three WNh stars in the SMC to constrain stellar evolution beyond the main sequence at low metallicity and to investigate the metallicity depend…
B -> phi K*, B -> phi Ks and New Physics
Alakabha Datta, Maxime Imbeault, David London
We consider the new-physics (NP) solution to the polarization puzzle in B -> phi K* decays. We note that any such solution must reproduce the data in B -> phi Ks, where there are d…
Direct Imaging of Multiple Planets Orbiting the Star HR 8799
C. Marois, B. Macintosh, T. Barman +5
Direct imaging of exoplanetary systems is a powerful technique that can reveal Jupiter-like planets in wide orbits, can enable detailed characterization of planetary atmospheres, a…
Search for the Z(4430)^- at BABAR
The BABAR Collaboration, B. Aubert
We report the results of a search for decay to or in $B^{-,0}\to \jpsiπ^- K^{0,+}$ and $B^{-,0}\to \psitwos π^- K^{0,+}$ decays. The data were colle…
Superintegrability with third order integrals of motion, cubic algebras and supersymmetric quantum mechanics II:Painleve transcendent potentials
Ian Marquette
We consider a superintegrable quantum potential in two-dimensional Euclidean space with a second and a third order integral of motion. The potential is written in terms of the four…
Spectroscopic analysis of DA white dwarfs from the McCook & Sion catalog
A. Gianninas, P. Bergeron, M. T. Ruiz
For some years now, we have been gathering optical spectra of DA white dwarfs in an effort to study and define the empirical ZZ Ceti instability strip. However, we have recently ex…
On the Age of the Widest Very Low Mass Binary
Etienne Artigau, David Lafreniere, Loic Albert +1
We have recently identified the widest very low-mass binary (2M0126AB), consisting of an M6.5V and an M8V dwarf with a separation of ~5100 AU, which is twice as large as that of th…
Cool White Dwarfs Identified in the Second Data Release of the UKIRT Infrared Deep Sky Survey
N. Lodieu, S. K. Leggett, P. Bergeron +1
We have paired the Second Data Release of the Large Area Survey of the UKIRT Infrared Deep Sky Survey with the Fifth Data Release of the Sloan Digital Sky Survey to identify ten co…
MOST discovers a multimode delta Scuti star in a triple system: HD 61199
M. Hareter, O. Kochukhov, H. Lehmann +13
A field star, HD 61199 (V ~ 8), simultaneously observed with Procyon by the MOST (Microvariability & Oscillations of STars) satellite in continuous runs of 34, 17, and 34 days in 2…
Electroweak precision constraints on the Lee-Wick Standard Model
Ezequiel Alvarez, Leandro Da Rold, Carlos Schat +1
We present the constraints on the parameter space of the Lee-Wick Standard Model coming from electroweak precision observables. The model predicts a large positive S and a negative…
Total integrals of global solutions to Painleve II
Jinho Baik, Robert Buckingham, Jeffery DiFranco +1
We evaluate the total integral from negative infinity to positive infinity of all global solutions to the Painleve II equation on the real line. The method is based on the interpla…
Photometric variability of WC9 stars
R. Fahed, A. F. J. Moffat, A. Z. Bonanos
Do some Wolf-Rayet stars owe their strong winds to something else besides radiation pressure? The answer to this question is still not entirely obvious, especially in certain Wolf-…
