Online Learning of Aggregate Knowledge about Non-linear Preferences Applied to Negotiating Prices and Bundles
Koye Somefun, Tomas Klos, Han La Poutré
In this paper, we consider a form of multi-issue negotiation where a shop negotiates both the contents and the price of bundles of goods with his customers. We present some key ins…
Negotiating over Bundles and Prices Using Aggregate Knowledge
Koye Somefun, Tomas Klos, Han La Poutré
Combining two or more items and selling them as one good, a practice called bundling, can be a very effective strategy for reducing the costs of producing, marketing, and selling g…
Oscillations in DC driven "barrier" discharges: numerical solutions, stability analysis and phase diagram
Danijela D. Sijacic, Ute Ebert, Ismail Rafatov
A short gas discharge layer sandwiched with a semiconductor layer between planar electrodes shows a variety of spatio-temporal patterns. The paper focusses on the spatially homogen…
Ageing effects around the glass and melting transitions in poly(dimethylsiloxane) visualized by resistance measurements
H. B. Brom, I. G. Romijn, J. G. Magis +2
The process of ageing in rubbers requires monitoring over long periods (days to years). To do so in non-conducting rubbers, small amounts of carbon-black particles were dispersed i…
Resonant scattering properties close to a p-wave Feshbach resonance
Frédéric Chevy, E. G. M. Van Kempen, T. Bourdel +6
We present a semi-analytical treatment of both the elastic and inelastic collisional properties near a p-wave Feshbach resonance. Our model is based on a simple three channel syste…
Self-contact for rods on cylinders
G. H. M. van der Heijden, M. A. Peletier, R. Planqué
We study self-contact phenomena in elastic rods that are constrained to lie on a cylinder. By choosing a particular set of variables to describe the rod centerline the variational…
Deviations of a random walk in a random scenery with stretched exponential tails
Remco van der Hofstad, Nina Gantert, Wolfgang König
Let (Z_n)_{n\in\N_0} be a d-dimensional random walk in random scenery, i.e., Z_n=\sum_{k=0}^{n-1}Y_{S_k} with (S_k)_{k\in\N_0} a random walk in Z^d and (Y_z)_{z\in Z^d} an i.i.d. s…
Parity Breaking in Nematic Tactoids
P. Prinsen, P. van der Schoot
We theoretically investigate under what conditions the director field in a spindle-shaped nematic droplet or tactoid obtains a twisted, parity-broken structure. By minimizing the s…
All-optical switching due to state-filling in quantum dots
R. Prasanth, J. E. M. Haverkort, A. Deepthy +8
We report all-optical switching due to state-filling in quantum dots (QDs) within a Mach-Zehnder Interferometric (MZI) switch. The MZI was fabricated using InGaAsP/InP waveguides c…
Critical Level Statistics of the Fibonacci Model
Michihiro Naka, Kazusumi Ino, Mahito Kohmoto
We numerically analyze spectral properties of the Fibonacci model which is a one-dimensional quasiperiodic system. We find that the energy levels of this model have the distributio…
Phase behavior and interfacial properties of nonadditive mixtures of Onsager rods
K. Shundyak, R. van Roij, P. van der Schoot
Within a second virial theory, we study bulk phase diagrams as well as the free planar isotropic-nematic interface of binary mixtures of nonadditive thin and thick hard rods. For s…
Feshbach Spectroscopy of a Shape Resonance
Thomas Volz, Stephan Dürr, Niels Syassen +3
We present a new spectroscopy technique for studying cold-collision properties. The technique is based on the association and dissociation of ultracold molecules using a magnetical…
Retarded Many-Sphere Hydrodynamic Interactions in a Viscous Fluid
P. P. J. M. Schram, A. S. Usenko, I. P. Yakimenko
An alternative method is suggested for the description of the velocity and pressure fields in an unbounded incompressible viscous fluid induced by an arbitrary number of spheres mo…
P-wave Feshbach resonances of ultra-cold Li
J. Zhang, E. G. M. Van Kempen, T. Bourdel +7
We report the observation of three p-wave Feshbach resonances of Li atoms in the lowest hyperfine state . The positions of the resonances are in good agreement with theo…
Distances in random graphs with finite variance degrees
Remco van der Hofstad, Gerard Hooghiemstra, Piet Van Mieghem
In this paper we study a random graph with nodes, where node has degree and are i.i.d. with $\prob(D_j\leq x)=F(x)$. We assume that $1-F(x)\leq c x^…
Theory of space-charge waves on gradient-profile relativistic electron beam: an analysis in propagating eigenmodes
Gianluca Geloni, Evgeni Saldin, Evgeni Schneidmiller +1
We developed an exact analytical treatment for space-charge waves within a relativistic electron beam in terms of (self-reproducing) propagating eigenmodes. This result is of obvio…
Exact asymptotics for fluid queues fed by multiple heavy-tailed on-off flows
Bert Zwart, Sem Borst, Michel Mandjes
We consider a fluid queue fed by multiple On-Off flows with heavy-tailed (regularly varying) On periods. Under fairly mild assumptions, we prove that the workload distribution is a…
Homotopy types of box complexes
Peter Csorba
In [MZ04] Matousek and Ziegler compared various topological lower bounds for the chromatic number. They proved that Lovasz's original bound [L78] can be restated as $\chr G \geq \i…
Charge manipulation and imaging of the Mn acceptor state in GaAs by Cross-sectional Scanning Tunneling Microscopy
A. M. Yakunin, A. Yu. Silov, P. M. Koenraad +3
An individual Mn acceptor in GaAs is mapped by Cross-sectional Scanning Tunneling Microscopy (X-STM) at room temperature and a strongly anisotropic shape of the acceptor state is o…

E. G. M. v. Kempen, B. Marcelis, S. J. J. M. F. Kokkelmans
We perform an analysis of recent experimental measurements and improve the lithium interaction potentials. For Li a consistent description can be given. We discuss theoretical…
Infinite canonical super-Brownian motion and scaling limits
Remco van der Hofstad
We construct a measure valued Markov process which we call infinite canonical super-Brownian motion, and which corresponds to the canonical measure of super-Brownian motion conditi…
