The implications of Galilean invariance for classical point particle lagrangians

Ziyang Hu

We explore the implications of the requirement of Galilean invariance for classical point particle lagrangians, in which the space is not assumed to be flat to begin with. We show…

The third body in the eclipsing binary AV CMi: Hot Jupiter or brown dwarf?

Alexios Liakos, Dimitris Mislis, Panagiotis Niarchos

New transit light curves of the third body in the system AV CMi have been obtained. The eclipsing pair's light curves were re-analysed with the W-D code and new absolute elements w…

A framework for structure-preserving submersions and some theorems in relativistic flows

Ziyang Hu

In this paper we first propose a framework of structure-preserving submersions, which generalises the concept of a Riemannian submersion, and dualises the concept of subgeometry, o…

Outward migration of a super-Earth in a disc with outward propagating density waves excited by a giant planet

E. Podlewska-Gaca, J. C. B. Papaloizou, E. Szuszkiewicz

In this paper we consider a new mechanism for stopping the inward migration of a low-mass planet embedded in a gaseous protoplanetary disc. It operates when a low-mass planet (for…

One-Bit Quantizers for Fading Channels

Tobias Koch, Amos Lapidoth

We study channel capacity when a one-bit quantizer is employed at the output of the discrete-time average-power-limited Rayleigh-fading channel. We focus on the low signal-to-noise…

Single crystal growth of YbRh2Si2 and YbIr2Si2

Cornelius Krellner, Sebastian Taube, Tanja Westerkamp +2

We report on the single crystal growth of the heavy-fermion compounds YbRh2Si2 and YbIr2Si2 using a high-temperature indium-flux technique. The optimization of the initial composit…

3-Manifolds and 3d Indices

Tudor Dimofte, Davide Gaiotto, Sergei Gukov

We identify a large class R of three-dimensional N=2 superconformal field theories. This class includes the effective theories T_M of M5-branes wrapped on 3-manifolds M, discussed…

Minimisation and reduction of 5-coverings of elliptic curves

Tom Fisher

We consider models for genus one curves of degree 5, which arise in explicit 5-descent on elliptic curves. We prove a theorem on the existence of minimal models with the same invar…

Direct genetic effects and their estimation from matched case-control data

Carlo Berzuini, Stijn Vansteelandt, Luisa Foco +2

In genetic association studies, a single marker is often associated with multiple, correlated phenotypes (e.g., obesity and cardiovascular disease, or nicotine dependence and lung…

Lazy Pointer Analysis

Uday P. Khedker, Alan Mycroft, Prashant Singh Rawat

Flow- and context-sensitive pointer analysis is generally considered too expensive for large programs; most tools relax one or both of the requirements for scalability. We formulat…

Powellsnakes II: a fast Bayesian approach to discrete object detection in multi-frequency astronomical data sets

Pedro Carvalho, Graça Rocha, M. P. Hobson +1

Powellsnakes is a Bayesian algorithm for detecting compact objects embedded in a diffuse background, and was selected and successfully employed by the Planck consortium in the prod…

Measurement of mixing and CP violation parameters in two-body charm decays

LHCb Collaboration, R. Aaij, C. Abellan Beteta +585

A study of mixing and indirect CP violation in D0 mesons through the determination of the parameters y_CP and A_Γ is presented. The parameter y_CP is the deviation from unity of th…

Measurement of charged particle multiplicities in collisions at TeV in the forward region

LHCb Collaboration, R. Aaij, C. Abellan Beteta +589

The charged particle production in proton-proton collisions is studied with the LHCb detector at a centre-of-mass energy of TeV in different intervals of pseudorapid…

Observational evidence of quasar feedback quenching star formation at high redshift

M. Cano-Diaz, R. Maiolino, A. Marconi +3

Most galaxy evolutionary models require quasar feedback to regulate star formation in their host galaxies. In particular, at high redshift, models expect that feedback associated w…

Signature of the long range triplet proximity effect in the density of states

Milos Knezevic, Luka Trifunovic, Zoran Radovic

We study the impact of the long-range spin-triplet proximity effect on the density of states (DOS) in planar SF1F2S Josephson junctions that consist of conventional superconductors…

Additive Gaussian Processes

David Duvenaud, Hannes Nickisch, Carl Edward Rasmussen

We introduce a Gaussian process model of functions which are additive. An additive function is one which decomposes into a sum of low-dimensional functions, each depending on only…

A nilpotent Freiman dimension lemma

Emmanuel Breuillard, Ben Green, Terence Tao

We prove that a K-approximate subgroup of an arbitrary torsion-free nilpotent group can be covered by a bounded number of cosets of a nilpotent subgroup of bounded rank, where the…

The Cosmological Supersymmetron

Philippe Brax, Anne-Christine Davis, Hans A. Winther

Recently, a supersymmetric model of dark energy coupled to cold dark matter, the supersymmetron, has been proposed. In the absence of cold dark matter, the supersymmetron field con…
