On Optimal Two Sample Homogeneity Tests for Finite Alphabets

Suppose we are given two independent strings of data from a known finite alphabet. We are interested in testing the null hypothesis that both the strings were drawn from the same distribution, assuming that the samples within each string are mutually indep ...

A Closer Look into G Protein Coupled Receptor Activation: X-Ray Crystallography and Long-Scale Molecular Dynamics Simulations

Ursula Röthlisberger, Stefano Vanni

G protein coupled receptors (GPCRs) are a large eukaryotic protein family of transmembrane receptors that react to a signal coming from the extracellular environment to generate an intracellular response through the activation of a signal transduction path ...

Assessing long-term land-use legacies in subalpine grasslands using a plant-trait based generic modelling framework

Aurélie Thébault

Background: In European mountains, where semi-natural grasslands have high cultural and nature conservation value, land-use legacies from past ploughing are associated with distinct floristic compositions and ecosystem properties. It remains unknown if the ...

Representing complex urban geometries in mesoscale modeling

Darren Robinson, Alain Clappier, Adil Rasheed

Real cities are comprised of a diverse, random arrangement of building positions, shapes, and sizes. Yet most of the urban parameterisations thus far developed share the assumption that a city is made up of either a regular array of parallelepipeds or infi ...

Temperature regime in a braided river system : an indicator for morphological heterogeneity and ecological potential

Anton Schleiss, Walter Gostner, Armin Julius Peter

Water temperature is one of the most important abiotic variables in streams and strongly influences the distribution and abundance of freshwater organisms. It might be assumed that in natural streams home to heterogenous habitats also a wide range of therm ...

Experimental characterization of the distribution of collagen fiber recruitment

Nikolaos Stergiopoulos, Sylvain Roy, Christophe Boss

The passive biomechanical behavior of blood vessels is generally modeled by a parallel arrangement of elastin and collagen, with collagen recruitment depending on vessel strain. We experimentally determined the collagen recruitment distribution using confo ...

Power Law and Exponential Decay of Intercontact Times between Mobile Devices

Jean-Yves Le Boudec, Milan Vojnovic

We examine the fundamental properties that determine the basic performance metrics for opportunistic communications. We first consider the distribution of intercontact times between mobile devices. Using a diverse set of measured mobility traces, we find a ...

Individual and Opportunity Factors Influencing Job Creation in New Firms

Marc Gruber

We build on multiple theoretical perspectives to investigate the unique and joint effects of individual- and opportunity-level factors affecting job creation in new firms. We tested hypotheses using survey data from individuals who transitioned from unempl ...

Novelty of Behaviour as a Basis for the Neuro-evolution of Operant Reward Learning

Andrea Soltoggio

An agent that deviates from a usual or previous course of action can be said to display novel or varying behaviour. Novelty of behaviour can be seen as the result of real or apparent randomness in decision making, which prevents an agent from repeating exa ...

Probing the differential adhesion hypothesis in the mammary gland using different bioengineered cell culture substrata

Léa Chanson

During tissue development, cells are able to form different layers and to self organize. At the moment, there are two principal hypotheses that try to explain cell sorting. The so called differential adhesion hypothesis (DAH) posits that cells organize acc ...
