Catalytic Asymmetric Functionalization of Inert Bonds and Synthesis of Bioactive Natural Products

The direct and enantioselective functionalization of inert bonds such as carbon-hydrogen and carbon-carbon is an emerging tool towards more sustainable and efficient synthetic methods. The individual activation pathways like concerted deprotonation metalat ...

Linear Manifold Approximation based on Differences of Tangents

Pascal Frossard, Sofia Karygianni

In this paper, we consider the problem of manifold approximation with affine subspaces. Our objective is to discover a set of low dimensional affine subspaces that represents manifold data accurately while preserving the manifold’s structure. For this purp ...

Some remarks on orbit sets of unimodular rows

Jean Fasel

Let A be a d-dimensional smooth algebra over a perfect field of characteristic not 2. Let Um(n+1)(A)/En+1 (A) be the set of unimodular rows of length n + 1 up to elementary transformations. If n >= (d + 2)/2, it carries a natural structure of group as disc ...

Group secret key agreement over state-dependent wireless broadcast channels

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani

We consider a group of m trusted nodes that aim to create a shared secret key K, using a state-dependent wireless broadcast channel that exists from one of the honest nodes to the rest of the nodes including a passive eavesdropper Eve. All of the trusted n ...

Elementary abelian subgroups in p-groups with a cyclic derived group

David Bornand

Let p be an arbitrary prime and let P be a finite p-group. The general objective of this paper is to obtain refined information on the homotopy type of the poset of all non-trivial elementary abelian subgroups of P, ordered by inclusion, and the poset of a ...

An Audio Visual Corpus for Emergent Leader Analysis

Daniel Gatica-Perez, Oya Aran, Dairazalia Sanchez Cortes

In this paper we discuss our experience designing and collecting a data corpus called ELEA (Emergent LEader Analysis), and describe the use of a light portable scenario to record small group meetings. The corpus was gathered with the aim of analyzing emerg ...

Secure key exchange in wireless networks

Christina Fragouli, László Czap

We investigate the problem of exchanging a se- cret key within a group of wireless devices. In particular, we are interested in information theoretically secure key exchange schemes that enable honest nodes of a multi-hop network to establish a secret grou ...

Paper Interface Design for Classroom Orchestration

Pierre Dillenbourg, Frédéric Kaplan, Sébastien Cuendet, Quentin Bonnard

Designing computer systems for educational purpose is a difficult task. While many of them have been developed in the past, their use in classrooms is still scarce. We make the hypothesis that this is because those systems take into account the needs of in ...

The group of unimodular automorphisms of a principal bundle and the Euler-Yang-Mills equations

Given a principal bundle G hooked right arrow P -> B (each being compact, connected and oriented) and a G-invariant metric h(P) on P which induces a volume form mu(P), we consider the group of all unimodular automorphisms SAut(P, mu(P)) := {phi is an eleme ...

Derandomization and Group Testing

Mahdi Cheraghchi Bashi Astaneh

The rapid development of derandomization theory, which is a fundamental area in theoretical computer science, has recently led to many surprising applications outside its initial intention. We will review some recent such developments related to combinator ...
