Generative models of the human connectome

Jean-Philippe Thiran, Alessandra Griffa, Patric Hagmann, Olaf Sporns

The human connectome represents a network map of the brain's wiring diagram and the pattern into which its connections are organized is thought to play an important role in cognitive function. The generative rules that shape the topology of the human conne ...

Nature and topology of the low-energy states in ZrTe5

Marco Grioni, Helmuth Berger, Luca Moreschini, Jens Christian Johannsen

Long known for its peculiar resistivity, showing a thus far unexplained anomalous peak as a function of temperature, ZrTe5 has recently received rising attention in a somewhat different context. While both theoretical and experimental results seem to point ...

Characterization of Cracks and their Effects on the Effective Transport Pathways in Ni-YSZ Anodes after Reoxidation Using X-Ray Nanotomography

Jian Wang, Jan Van Herle, Siyuan Wang, Arata Nakajo, Fabio Greco

Reduction-oxidation cycling of Ni-based electrodes for solid oxide fuel/electrolysis cells irreversibly alters their microstructure and can cause the fracture of the electrolyte. Non-destructive 3-D imaging enables tracking of microstructural changes that ...

Constrained Reachability and Trajectory Generation for Flat Systems

Timm Faulwasser

We consider the problem of trajectory generation for constrained differentially flat systems. Based on the topological properties of the set of admissible steady state values of a flat output we derive conditions which allow for an a priori verification of ...

Self-Assembly of a Giant Molecular Solomon Link from 30 Subcomponents

Rosario Scopelliti, Kay Severin, Yury Tsybin, Konstantin Nagornov, Konstantin Zhurov, Clément Schouwey

The synthesis of topologically complex structures, such as links and knots, is one of the current challenges in supramolecular chemistry. The so-called Solomon link consists of two doubly interlocked rings. Despite being a rather simple link from a topolog ...

What Future for the Urban Underground? Subsurface and Surface Potential in San Antonio, Texas

Michael Robert Doyle

The Deep City project at the École polytechnique fédérale de Lausanne has, for the past several years, been developing a method to identify and qualify the urban areas where underground development is high, particularly for human activities. The fourth dis ...

Local topological properties of brain connectivity in minimally-disabled multiple sclerosis patients

Dimitri Nestor Alice Van De Ville, Djalel Eddine Meskaldji, Jonas Richiardi

Understanding brain diseases can benefit from studying network organization of functional connectivity (FC) during resting state. Here we study the local topological properties of FC in minimally-disabled multiple sclerosis (MS) patients by comparison of t ...

Topological pumping in class-D superconducting wires

Marco Gibertini

We study adiabatic pumping at a normal metal/class-D superconductor hybrid interface when superconductivity is induced through the proximity effect in a spin-orbit coupled nanowire in the presence of a tilted Zeeman field. When the induced order parameter ...

Multi-Robot Topological Exploration Using Olfactory Cues

Ali Marjovi

This paper presents a distributed multi-robot system to search for odor sources inside unknown environments. The robots cooperatively explore the whole environment and generate its topological map. The exploration method is a decentralized frontier based a ...

Discrete Scale Axis Representations for 3D Geometry

Mark Pauly

This paper addresses the fundamental problem of computing stable medial representations of 3D shapes. We propose a spatially adaptive classification of geometric features that yields a robust algorithm for generating medial representations at different lev ...
