Kepler Asteroseismology Program: Introduction and First Results

Ronald L. Gilliland, T. M. Brown, J. Christensen-Dalsgaard +32

Asteroseismology involves probing the interiors of stars and quantifying their global properties, such as radius and age, through observationsof normal modes of oscillation. The te…

Hydrodynamics of fundamental matter

Francesco Bigazzi, Aldo L. Cotrone, Javier Tarrio

First and second order transport coefficients are calculated for the strongly coupled N=4 SYM plasma coupled to massless fundamental matter in the Veneziano limit. The results, inc…

Gravitational settling in pulsating subdwarf B stars and their progenitors

Haili Hu, E. Glebbeek, A. A. Thoul +4

Diffusion of atoms can be important during quiescent phases of stellar evolution. Particularly in the very thin inert envelopes of subdwarf B stars, diffusive movements will consid…

Painlevé VI and the Unitary Jacobi ensembles

Yang Chen, Lun Zhang

The six Painlevé transcendants which originally appeared in the studies of ordinary differential equations have been found numerous applications in physical problems. The well-know…

Polytool: polynomial interpretations as a basis for termination analysis of Logic programs

Manh Thang Nguyen, Danny De Schreye, Jürgen Giesl +1

Our goal is to study the feasibility of porting termination analysis techniques developed for one programming paradigm to another paradigm. In this paper, we show how to adapt term…

The effect of longitudinal flow on resonantly damped kink oscillations

J. Terradas, M. Goossens, I. Ballai

The most promising mechanism acting towards damping the kink oscillations of coronal loops is resonant absorption. In this context most of previous studies neglected the effect of…

Stable fractional flux vortices in mesoscopic superconductors

L. F. Chibotaru, V. H. Dao

Conventional superconductors have vortices carrying integer multiples of magnetic flux quantum while unconventional ones, with p- or d-wave order parameter, allow half-integer flux…

Some Modifications of the Theorem of Beltrami

Steven Verpoort

The two main topics of this text are as follows: Firstly, three modifications of the theorem of Beltrami will be presented for diffeomorphisms between Riemannian manifolds and a sp…

Study of sdO models: mode trapping

C. Rodríguez-López, A. Moya, R. Garrido +3

We present the first description of mode trapping for sdO models. Mode trapping of gravity modes caused by the He/H chemical transition is found for a particular model, providing a…

Beam Energy Considerations for Gold Nano-Particle Enhanced Radiation Treatment

F. Van den Heuvel, J. P. Locquet, S. Nuyts

Purpose: A novel approach using nano technology enhanced radiation modalities is investigated. The proposed methodology uses antibodies labeled with organically inert metals with a…

Kelvin-Helmholtz instability in coronal magnetic flux tubes due to azimuthal shear flows

R. Soler, J. Terradas, R. Oliver +2

Transverse oscillations of coronal loops are often observed and have been theoretically interpreted as kink magnetohydrodynamic (MHD) modes. Numerical simulations by Terradas et al…

Linear model for fast background subtraction in oligonucleotide microarrays

K. Myriam Kroll, Gerard T. Barkema, Enrico Carlon

One important preprocessing step in the analysis of microarray data is background subtraction. In high-density oligonucleotide arrays this is recognized as a crucial step for the g…

Nonequilibrium Linear Response for Markov Dynamics, II: Inertial Dynamics

Marco Baiesi, Eliran Boksenbojm, Christian Maes +1

We continue our study of the linear response of a nonequilibrium system. This Part II concentrates on models of open and driven inertial dynamics but the structure and the interpre…

Efficient and coherent excitation transfer across disordered molecular networks

Torsten Scholak, Fernando de Melo, Thomas Wellens +2

We show that finite-size, disordered molecular networks can mediate highly efficient, coherent excitation transfer which is robust against ambient dephasing and associated with str…

Geometry of the quantum projective plane

Francesco D'Andrea, Giovanni Landi

We review some of the geometry of the quantum projective plane with emphasis on the construction of a differential calculus and of the Dirac operator (of a spin^c-structure). We al…

Davies maps for qubits and qutrits

Wojciech Roga, Mark Fannes, Karol Zyczkowski

We investigate the dynamics of an N -level quantum system weakly coupled to a thermal reservoir. For any fixed temperature of the bath there exists a natural reference state: the e…

Coordination via Interaction Constraints I: Local Logic

Dave Clarke, José Proença

Wegner describes coordination as constrained interaction. We take this approach literally and define a coordination model based on interaction constraints and partial, iterative an…

Thermodynamics of histories for the one-dimensional contact process

Jef Hooyberghs, Carlo Vanderzande

The dynamical activity K(t) of a stochastic process is the number of times it changes configuration up to time t. It was recently argued that (spin) glasses are at a first order dy…

Stability under integration of sums of products of real globally subanalytic functions and their logarithms

Raf Cluckers, Daniel J. Miller

We study Lebesgue integration of sums of products of globally subanalytic functions and their logarithms, called constructible functions. Our first theorem states that the class of…

Relating chronology protection and unitarity through holography

Joris Raeymaekers, Dieter Van den Bleeken, Bert Vercnocke

We give a simple nonsupersymmetric example in which chronology protection follows from unitarity and the AdS/CFT correspondence. We consider a ball of homogeneous, rotating dust in…
