Distance function design and Lyapunov techniques for the stability of hybrid trajectories

J. J. Benjamin Biemond, W. P. Maurice H. Heemels, Ricardo G. Sanfelice +1

The comparison between time-varying hybrid trajectories is crucial for tracking, observer design and synchronisation problems for hybrid systems with state-triggered jumps. In this…

Constraints for the aperiodic O-mode streaming instability

M. Lazar, R. Schlickeiser, S. Poedts +2

In plasmas where the thermal energy density exceeds the magnetic energy density (), the aperiodic ordinary mode (O-mode) instability is driven by an excess of para…

On the kinetics that moves Myosin V

Christian Maes, Winny O'Kelly de Galway

Molecular motor proteins such as Myosin V, Dynein or Kinesin are no ratchets, at least not with a flashing asymmetric potential; the crucial asymmetry is in the dynamical activity.…

Surprising detection of an equatorial dust lane on the AGB star IRC+10216

S. V. Jeffers, M. Min, L. B. F. M. Waters +6

Understanding the formation of planetary nebulae remains elusive because in the preceding asymtotic giant branch (AGB) phase these stars are heavily enshrouded in an optically thic…

Gauged R-symmetry and its anomalies in 4D N=1 supergravity and phenomenological implications

I. Antoniadis, D. M. Ghilencea, R. Knoops

We consider a class of models with gauged U(1)_R symmetry in 4D N=1 supergravity that have, at the classical level, a metastable ground state, an infinitesimally small (tunable) po…

A parallel multistate framework for atomistic non-equilibrium reaction dynamics of solutes in strongly interacting organic solvents

David R. Glowacki, Andrew J. Orr-Ewing, Jeremy N. Harvey

We describe a parallel linear-scaling computational framework developed to implement arbitrarily large multi-state empirical valence bond (MS-EVB) calculations within CHARMM. Force…

Oscillating red-giant stars in eccentric binary systems

P. G. Beck, K. Hambleton, J. Vos +4

The unparalleled photometric data obtained by NASA's Kepler Space Telescope has led to improved understanding of red-giant stars and binary stars. We discuss the characterization o…

Constraining interactions mediated by axion-like particles with ultracold neutrons

S. Afach, G. Ban, G. Bison +35

We report a new limit on a possible short range spin-dependent interaction from the precise measurement of the ratio of Larmor precession frequencies of stored ultracold neutrons a…

Temporal coherence of one-dimensional non-equilibrium quantum fluids

Kai Ji, Vladimir N. Gladilin, Michiel Wouters

We theoretically investigate the time dependence of the first order coherence function for a one-dimensional driven dissipative non-equilibrium condensate. Simulations on the gener…

Kepler photometry of RRc stars: peculiar double-mode pulsations and period doubling

P. Moskalik, R. Smolec, K. Kolenberg +11

We present the analysis of four first overtone RR Lyrae stars observed with the Kepler space telescope, based on data obtained over nearly 2.5yr. All four stars are found to be mul…

Censorship Resistance: Let a Thousand Flowers Bloom?

Tariq Elahi, Steven J. Murdoch, Ian Goldberg

This paper argues that one of the most important decisions in designing and deploying censorship resistance systems is whether one set of system options should be selected (the bes…

The hard edge tacnode process and the hard edge Pearcey process with non-intersecting squared Bessel paths

Steven Delvaux, Bálint Vető

A system of non-intersecting squared Bessel processes is considered which all start from one point and they all return to another point. Under the scaling of the starting and endin…

Multilevel Hierarchical Kernel Spectral Clustering for Real-Life Large Scale Complex Networks

Raghvendra Mall, Rocco Langone, Johan A. K. Suykens

Kernel spectral clustering corresponds to a weighted kernel principal component analysis problem in a constrained optimization framework. The primal formulation leads to an eigen-d…

What asteroseismology can do for exoplanets

Vincent Van Eylen, Mikkel N. Lund, Victor Silva Aguirre +12

We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of ste…
