Geneva, from car-euphoria to opening of the borders

Over the last two decades, urban planning has been reapplied in several European countries: common tendencies that underline the reform of planning procedures are the generalization of sustainable development and the reorganization of local government. Bri ...

Active Learning of Multi-Index Function Models

Volkan Cevher, Hemant Tyagi

We consider the problem of actively learning \textit{multi-index} functions of the form

f(x) = g(Ax)= \sum_{i=1}^k g_i(a_i^Tx)

from point evaluations of

f

. We assume that the function

f

is defined on an

\ell_2

-ball in

\Real^d

,

g

is twice contin ...

Minimal State Representation for Open Fluid-Fluid Reaction Systems

Dominique Bonvin, Philippe Müllhaupt, Michael Amrhein, Nirav Pravinbhai Bhatt

Reaction systems are typically represented by first-principles models that describe the evolution of the states (typically concentrations, volume and temperature) by means of conservation equations of differential nature and constitutive equations of algeb ...

Hessian-Based Norm Regularization for Image Restoration With Biomedical Applications

Michaël Unser, Aurélien Bourquard, Stamatios Lefkimmiatis

We present nonquadratic Hessian-based regularization methods that can be effectively used for image restoration problems in a variational framework. Motivated by the great success of the total-variation (TV) functional, we extend it to also include second- ...

Unaligned Rebound Attack: Application on Keccak

Alexandre Raphaël Duc

We analyze the internal permutations of Keccak, one of the NIST SHA-3 competition finalists, in regard to differential properties. By carefully studying the elements composing those permutations, we are able to derive most of the best known differential pa ...

Non-genetic inheritance and the patterns of antagonistic coevolution

Marcel Salathé

Antagonistic species interactions can lead to coevolutionary genotype or phenotype frequency oscillations, with important implications for ecological and evolutionary processes. However, direct empirical evidence of such oscillations is rare. The rarity of ...

Knowledge Recombination across Technological Boundaries: Scientists versus Engineers

Marc Gruber

Building on the seminal work of Allen (1977), we contribute to the emerging micro-level theory of knowledge recombination by examining how individual-level characteristics of inventors affect the breadth of their technological recombinations. Our data set ...

Application of Legendrian Foliations in Differential Flatness Problems

Philippe Müllhaupt, Basile Graf

Instances of control systems are presented for which dynamical feedback linearizability can be assessed from differential forms of highest relative degree after some “contact” transformation has been applied. This bypasses the need to find a polynomial dif ...

Direct Visualization of the Axial Phase Evolution of Light Fields Emerging from Microstructures

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We investigate the axial phase evolution of light emerging from microstructures. The high-resolution interference microscope (HRIM) allows to record three-dimensional (3D) phase distributions in differential and propagation modes along the longitudinal dir ...

Spatial effects on species persistence and implications for biodiversity

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

Natural ecosystems are characterized by striking diversity of form and functions and yet exhibit deep symmetries emerging across scales of space, time, and organizational complexity. Species-area relationships and species-abundance distributions are exampl ...
