Task Elimination may Actually Increase Throughput Time

D. M. M. Schunselaar, H. M. W. Verbeek

The well-known Task Elimination redesign principle suggests to remove unnecessary tasks from a process to improve on time and cost. Although there seems to be a general consensus t…

Counting cliques and cycles in scale-free inhomogeneous random graphs

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

Scale-free networks contain many small cliques and cycles. We model such networks as inhomogeneous random graphs with regularly varying infinite-variance weights. For these models,…

A bouncing oil droplet in a stratified liquid and its sudden death

Yanshen Li, Christian Diddens, Andrea Prosperetti +3

Droplets can self-propel when immersed in another liquid in which a concentration gradient is present. Here we report the experimental and numerical study of a self-propelling oil…

On the competition between dislocation transmission and crack nucleation at phase boundaries

F. Bormann, R. H. J. Peerlings, M. G. D. Geers

The interaction of dislocations with phase boundaries is a complex phenomenon, that is far from being fully understood. A 2D Peierls-Nabarro finite element (PN-FE) model for studyi…

Self-stresses control stiffness and stability in overconstrained disordered networks

Anwesha Bose, Mathijs F. J. Vermeulen, Cornelis Storm +1

We investigate the interplay between pre-stress and mechanical properties in random elastic networks. To do this in a controlled fashion, we introduce an algorithm for creating ran…

Convex Polygons in Cartesian Products

Jean-Lou De Carufel, Adrian Dumitrescu, Wouter Meulemans +4

We study several problems concerning convex polygons whose vertices lie in a Cartesian product of two sets of real numbers (for short, \emph{grid}). First, we prove that every…

Enhancing Discrete Choice Models with Representation Learning

Brian Sifringer, Virginie Lurkin, Alexandre Alahi

In discrete choice modeling (DCM), model misspecifications may lead to limited predictability and biased parameter estimates. In this paper, we propose a new approach for estimatin…

Quantum Equivalence of the DLP and CDHP for Group Actions

Steven Galbraith, Lorenz Panny, Benjamin Smith +1

In this short note we give a polynomial-time quantum reduction from the vectorization problem (DLP) to the parallelization problem (CDHP) for group actions. Combined with the trivi…

Matroids over one-dimensional groups

Guus P. Bollen, Dustin Cartwright, Jan Draisma

We develop the theory of matroids over one-dimensional algebraic groups, with special emphasis on positive characteristic. In particular, we compute the Lindström valuations and Fr…

The dimension of an amoeba

Jan Draisma, Johannes Rau, Chi Ho Yuen

Answering a question by Nisse and Sottile, we derive a formula for the dimension of the amoeba of an irreducible algebraic variety.

Multivalent "Attacker & Guard" Strategy for Targeting Surfaces with Low Receptor Density

Nicholas B. Tito

Multivalent particles, i.e. microscopic constructs having multiple ligands, can be used to target surfaces selectively depending on their receptor density. Typically, there is a sh…

The effect of the liquid layer thickness on the dissolution of immersed surface droplets

Qingguang Xie, Jens Harting

Droplets on a liquid-immersed solid surface are key elements in many applications, such as high-throughput chemical analysis and droplet-templated porous materials. Such surface dr…

How antagonistic salts cause nematic ordering and behave like diblock copolymers

David Jung, Nicolas Rivas, Jens Harting

We present simulation results and an explanatory theory on how antagonistic salts affect the spinodal decomposition of binary fluid mixtures. We find that spinodal decomposition is…
