A Large-Scale Characterization of How Readers Browse Wikipedia

Tiziano Piccardi, Robert West, Akhil Arora

Despite the importance and pervasiveness of Wikipedia as one of the largest platforms for open knowledge, surprisingly little is known about how people navigate its content when seeking information. To bridge this gap, we present the first systematic large ...

Wikipedia Reader Navigation: When Synthetic Data Is Enough

Tiziano Piccardi, Robert West, Akhil Arora, Alberto Garcia Duran

Every day millions of people read Wikipedia. When navigating the vast space of available topics using hyperlinks, readers describe trajectories on the article network. Understanding these navigation patterns is crucial to better serve readers' needs and ad ...

Optimization and Real-Time Aspects of Aircraft Model-Based Navigation

Gabriel François Laupré

The Vehicle Dynamic Model (VDM) based navigation of fixed-wing drones determines the airborne trajectory in conjunction with Inertial Measurement Unit (IMU) sensors. Without Global Navigation Satellite Systems (GNSS) signals, this method estimates navigati ...

More than a border effect. Ordinary politicization and struggles of belonging in a Swiss border municipality

Garance Clément, Alexis Gumy

Can living near a national border have an effect on the politicization of individuals? To answer this question, this article challenges the results put forward by some European Border Studies scholars granting the border a major role in the construction of ...

Species conservation in the face of global environmental changes: surface-based modelling of geo-environmental data to identify vulnerable populations

Estelle Rochat

Human activities are resulting in many land-use changes, particularly due to urbanisation and intensification of agricultural practices. Because of these changes, in addition to climate change, many species are facing habitat degradation. In order to avoid ...

Trait-specific dispersal of bacteria in heterogeneous porous environments: from pore to porous medium scale

Tom Ian Battin, David Scheidweiler, Hannes Markus Peter, Filippo Miele

The dispersal of organisms controls the structure and dynamics of populations and communities, and can regulate ecosystem functioning. Predicting dispersal patterns across scales is important to understand microbial life in heterogeneous porous environment ...

Evolving biodiversity patterns in changing river networks

Andrea Rinaldo, Enrico Bertuzzo

Biodiversity patterns are governed by landscape structure and dispersal strategies of residing organisms. Landscape, however, changes, and dispersal strategies evolve with it. It is unclear how these biological and geomorphological changes interplay to aff ...

Assessment of VDM-based autonomous navigation of a UAV under operational conditions

Jan Skaloud, Mehran Khaghani

This paper presents extensions and practical realization of a previously proposed novel approach to navigation and sensor integration for small unmanned aerial vehicles (UAV). The proposed approach employs vehicle dynamic model (VDM) as process model withi ...

Autonomous Vehicle Dynamic Model-Based Navigation for Small UAVs

Jan Skaloud, Mehran Khaghani

This paper presents a novel approach to autonomous navigation for small UAVs, with no extra sensor added to the conventional INS/GNSS setup. The proposed method significantly increases the accuracy and reliability of autonomous navigation, especially for s ...

Metapopulation persistence and species spread in river networks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

River networks define ecological corridors characterised by unidirectional streamflow, which may impose downstream drift to aquatic organisms or affect their movement. Animals and plants manage to persist in riverine ecosystems, though, which in fact harbo ...

Measuring the relative effect of factors affecting species distribution model predictions

Anthony Christopher Davison, Emeric Rolland Georges Thibaud

Species distribution models are increasingly used to address conservation questions, so their predictive capacity requires careful evaluation. Previous studies have shown how individual factors used in model construction can affect prediction. Although som ...

Emerging predictable features of replicated biological invasion fronts

Andrea Rinaldo, Francesco Carrara, Andrea Giometto, Florian Altermatt

Biological dispersal shapes species' distribution and affects their coexistence. The spread of organisms governs the dynamics of invasive species, the spread of pathogens, and the shifts in species ranges due to climate or environmental change. Despite its ...

Theoretical and Experimental Studies of Dendritic Metacommunities

Francesco Carrara

The present thesis deals with the understanding of the origins and the mechanisms of maintenance of biodiversity in natural landscapes, in particular by identifying key processes that define large-scale patterns of abundance and diversity. Biological commu ...

Capillary Self-Alignment of Mesoscopic Foil Components for Sensor-Systems-in-Foil

Massimo Mastrangeli

This paper reports on the effective use of capillary self-alignment for low-cost and time-efficient assembly of heterogeneous foil components into a smart electronic identification label. Particularly, we demonstrate the accurate (better than 50 μm) alignm ...

Evolution of dispersal in explicitly spatial metacommunities

Andrea Rinaldo

We apply an evolutionary game theoretic approach to the evolution of dispersal in explicitly spatial metacommunities, using a flexible parametric class of dispersal kernels, namely 2Dt kernels, and study the resulting evolutionary dynamics and outcomes. We ...

Have we underestimated the importance of humans in the biogeography of free-living terrestrial microorganisms?

The role of humans in the global dispersal of free-living terrestrial microorganisms has received surprisingly little attention in the literature, compared with the frequent discussions of human dispersal for aquatic microbes. Here I argue that this area n ...

On neutral metacommunity patterns of river basins at different scales of aggregation

Andrea Rinaldo, Enrico Bertuzzo

Neutral metacommunity models for spatial biodiversity patterns are implemented on river networks acting as ecological corridors at different resolution. Coarse-graining elevation fields (under the constraint of preserving the basin mean elevation) produce ...

On the geographic range of freshwater ﬁsh in river basins

Andrea Rinaldo, Enrico Bertuzzo

We study the observed geographic distribution of freshwater fish species in the Mississippi-Missouri river system, focusing on the size and spatial distribution of geographic ranges. We use a particular metric of geographic distribution known as environmen ...

POLLEN CLUMPING AND WIND DISPERSAL IN AN INVASIVE ANGIOSPERM

Marc Parlange, Michael David Martin, Charles Vivant Ignacio Meneveau

Pollen dispersal is a fundamental aspect of plant reproductive biology that maintains connectivity between spatially separated populations. Pollen clumping, a characteristic feature of insect-pollinated plants, is generally assumed to be a detriment to win ...
