Solid Capillarity: When and How does Surface Tension Deform Soft Solids?

Bruno Andreotti, Oliver Baeumchen, Francois Boulogne +6

Soft solids differ from stiff solids in an important way: their surface stresses can drive large deformations. Based on a topical workshop held in the Lorentz Center in Leiden, thi…

Bisimulation of Labelled State-to-Function Transition Systems Coalgebraically

Diego Latella, Mieke Massink, Erik P De Vink

Labeled state-to-function transition systems, FuTS for short, are characterized by transitions which relate states to functions of states over general semirings, equipped with a ri…

Lubrication of soft viscoelastic solids

Anupam Pandey, Stefan Karpitschka, Kees Venner +1

Lubrication flows appear in many applications in engineering, biophysics, and in nature. Separation of surfaces and minimisation of friction and wear is achieved when the lubricati…

Dominant poles and tail asymptotics in the critical Gaussian many-sources regime

A. J. E. M. Janssen, Johan S. H. van Leeuwaarden

The dominant pole approximation (DPA) is a classical analytic method to obtain from a generating function asymptotic estimates for its underlying coefficients. We apply DPA to a di…

Clustering time series under the Fréchet distance

Anne Driemel, Amer Krivošija, Christian Sohler

The Fréchet distance is a popular distance measure for curves. We study the problem of clustering time series under the Fréchet distance. In particular, we give -a…

Drop deformation by laser-pulse impact

Hanneke Gelderblom, Henri Lhuissier, Alexander L. Klein +4

A free-falling absorbing liquid drop hit by a nanosecond laser-pulse experiences a strong recoil-pressure kick. As a consequence, the drop propels forward and deforms into a thin s…

Axisymmetric multiphase Lattice Boltzmann method for generic equations of state

Sten A. Reijers, Hanneke Gelderblom, Federico Toschi

We present an axisymmetric lattice Boltzmann model based on the Kupershtokh et al. multiphase model that is capable of solving liquid-gas density ratios up to . Appropriate s…

Continuous integration in a social-coding world: Empirical evidence from GitHub. **Updated version with corrections**

Bogdan Vasilescu, Stef van Schuylenburg, Jules Wulms +2

Continuous integration is a software engineering practice of frequently merging all developer working copies with a shared main branch, e.g., several times a day. With the advent o…

A convergent mass conservative numerical scheme based on mixed finite elements for two-phase flow in porous media

Florin Adrian Radu, Kundan Kumar, Jan Martin Nordbotten +1

In this work we present a mass conservative numerical scheme for two-phase flow in porous media. The model for flow consists on two fully coupled, non-linear equations: a degenerat…

Analysis of Vessel Connectivities in Retinal Images by Cortically Inspired Spectral Clustering

Marta Favali, Samaneh Abbasi-Sureshjani, Bart ter Haar Romeny +1

Retinal images provide early signs of diabetic retinopathy, glaucoma, and hypertension. These signs can be investigated based on microaneurysms or smaller vessels. The diagnostic b…

Persistence-driven durotaxis: Generic, directed motility in rigidity gradients

Elizaveta A. Novikova, Matthew Raab, Dennis E. Discher +1

Cells move differently on substrates with different elasticities. In particular, the persistence time of their motion is higher on stiffer substrates. We show that this behavior wi…

Robust heavy-traffic approximations for service systems facing overdispersed demand

Britt W. J. Mathijsen, A. J. E. M. Janssen, Johan S. H. van Leeuwaarden +1

Arrival processes to service systems often display fluctuations that are larger than anticipated under the Poisson assumption, a phenomenon that is referred to as overdispersion. M…
