Non-backtracking random walk

Robert Fitzner, Remco van der Hofstad

We consider non-backtracking random walk (NBW) in the nearest-neighbor setting on the Zd-lattice and on tori. We evaluate the eigensystem of the m X m-dimensional transition matrix…

Heuristics Miners for Streaming Event Data

Andrea Burattin, Alessandro Sperduti, Wil M. P. van der Aalst

More and more business activities are performed using information systems. These systems produce such huge amounts of event data that existing systems are unable to store and proce…

Flow past superhydrophobic surfaces with cosine variation in local slip length

Evgeny S. Asmolov, Sebastian Schmieschek, Jens Harting +1

Anisotropic super-hydrophobic surfaces have the potential to greatly reduce drag and enhance mixing phenomena in microfluidic devices. Recent work has focused mostly on cases of su…

The clustering morphology of freely rising deformable bubbles

Yoshiyuki Tagawa, Ivo Roghair, Vivek N. Prakash +4

We investigate the clustering morphology of a swarm of freely rising deformable bubbles. A three-dimensional Voronoï analysis enables us to quantitatively distinguish between two t…

Optimality of the triangular lattice for a particle system with Wasserstein interaction

D. P. Bourne, M. A. Peletier, F. Theil

We prove strong crystallization results in two dimensions for an energy that arises in the theory of block copolymers. The energy is defined on sets of points and their weights, or…

Lagrangian single particle turbulent statistics through the Hilbert-Huang Transform

Yongxiang Huang, Luca Biferale, Enrico Calzavarini +2

The Hilbert-Huang transform is applied to analyze single particle Lagrangian velocity data from numerical simulations of hydrodynamic turbulence. The velocity trajectory is describ…

From individual behaviour to an evaluation of the collective evolution of crowds along footbridges

Luca Bruno, Alessandro Corbetta, Andrea Tosin

This paper proposes a crowd dynamic macroscopic model grounded on microscopic phenomenological observations which are upscaled by means of a formal mathematical procedure. The actu…

A Multi-Orientation Analysis Approach to Retinal Vessel Tracking

Erik Bekkers, Remco Duits, Tos Berendschot +1

This paper presents a method for retinal vasculature extraction based on biologically inspired multi-orientation analysis. We apply multi-orientation analysis via so-called inverti…

Short paths for first passage percolation on the complete graph

Maren Eckhoff, Jesse Goodman, Remco van der Hofstad +1

We study the complete graph equipped with a topology induced by independent and identically distributed edge weights. The focus of our analysis is on the weight W_n and the number…

Combining Insertion and Deletion in RNA-editing Preserves Regularity

E. P. de Vink, H. Zantema, D. Bošnački

Inspired by RNA-editing as occurs in transcriptional processes in the living cell, we introduce an abstract notion of string adjustment, called guided rewriting. This formalism all…

Adaptive nonparametric Bayesian inference using location-scale mixture priors

R. de Jonge, J. H. van Zanten

We study location-scale mixture priors for nonparametric statistical problems, including multivariate regression, density estimation and classification. We show that a rate-adaptiv…

Achievable Performance in Product-Form Networks

Jaron Sanders, Sem C. Borst, Johan S. H. van Leeuwaarden

We characterize the achievable range of performance measures in product-form networks where one or more system parameters can be freely set by a network operator. Given a product-f…

Controlled Nanoparticle Formation by Diffusion Limited Coalescence

R. Stepanyan, J. G. J. L. Lebouille, J. J. M. Slot +2

Polymeric nanoparticles (NPs) have a great application potential in science and technology. Their functionality strongly depends on their size. We present a theory for the size of…

Maximum Likelihood Duality for Determinantal Varieties

Jan Draisma, Jose Rodriguez

In a recent paper, Hauenstein, Sturmfels, and the second author discovered a conjectural bijection between critical points of the likelihood function on the complex variety of matr…

Queues and risk models with simultaneous arrivals

E. S. Badila, O. J. Boxma, J. A. C. Resing +1

We focus on a particular connection between queueing and risk models in a multi-dimensional setting. We first consider the joint workload process in a queueing model with parallel…

Logarithmic asymptotics for multidimensional extremes under non-linear scalings

Kamil Marcin Kosinski, Michel Mandjes

Let be a sequence of random vectors in , . This paper considers the logarithmic asymptotics of the extremes o…

A Rewriting View of Simple Typing

Aaron Stump, Garrin Kimmell, Hans Zantema +1

This paper shows how a recently developed view of typing as small-step abstract reduction, due to Kuan, MacQueen, and Findler, can be used to recast the development of simple type…

Growth and optical properties of axial hybrid III-V/Si nanowires

Moïra Hocevar, George Immink, Marcel Verheijen +4

Hybrid silicon nanowires with an integrated light-emitting segment can significantly advance nanoelectronics and nanophotonics. They would combine transport and optical characteris…

Fast spin-orbit qubit in an indium antimonide nanowire

J. W. G. van den Berg, S. Nadj-Perge, V. S. Pribiag +4

Due to the strong spin-orbit interaction in indium antimonide, orbital motion and spin are no longer separated. This enables fast manipulation of qubit states by means of microwave…

Ponderomotive manipulation of cold subwavelength plasmas

P. W. Smorenburg, L. P. J. Kamp, O. J. Luiten

Ponderomotive forces (PFs) induced in cold subwavelength plasmas by an externally applied electromagnetic wave are studied analytically. To this end, the plasma is modeled as a sph…
