Fluctuation symmetry leads to GENERIC equations with non-quadratic dissipation

Richard C. Kraaij, Alexandre Lazarescu, Christian Maes +1

We develop a formalism to discuss the properties of GENERIC systems in terms of corresponding Hamiltonians that appear in the characterization of large-deviation limits. We demonst…

Episodic accretion in binary protostars emerging from self-gravitating solar mass cores

R. Riaz, S. Vanaverbeke, D. R. G. Schleicher

Observations show a large spread in the luminosities of young protostars, which are frequently explained in the context of episodic accretion. We here test this scenario using nume…

Towards an explicit model of large field inflation

Juan Diaz Dorronsoro, Marjorie Schillo

The unwinding inflation mechanism is studied in a type IIB flux compactification where all moduli are stabilized using flux, non-perturbative effects, and the leading alpha' correc…

Crystal-to-crystal transition of ultrasoft colloids under shear

J. Ruiz-Franco, J. Marakis, N. Gnan +5

Ultrasoft colloids typically do not spontaneously crystallize, but rather vitrify, at high concentrations. Combining in-situ rheo-SANS experiments and numerical simulations we show…

Logo Synthesis and Manipulation with Clustered Generative Adversarial Networks

Alexander Sage, Eirikur Agustsson, Radu Timofte +1

Designing a logo for a new brand is a lengthy and tedious back-and-forth process between a designer and a client. In this paper we explore to what extent machine learning can solve…

Identifiability beyond Kruskal's bound for symmetric tensors of degree 4

Elena Angelini, Luca Chiantini, Nick Vannieuwenhoven

We show how methods of algebraic geometry can produce criteria for the identifiability of specific tensors that reach beyond the range of applicability of the celebrated Kruskal cr…

Characterizing the turbulent porosity of stellar-wind structure generated by the line-deshadowing instability

Stanley P. Owocki, Jon O. Sundqvist

We analyze recent 2D simulations of the nonlinear evolution of the line-deshadowing instability (LDI) in hot-star winds, to quantify how the associated highly clumped density struc…
