Electrical detection of spin hyperpolarization in InP

Jean-Philippe Ansermet, Christian Caspers

The electrical detection of surface spin polarization in Indium Phosphide (InP) is demonstrated. Using a planar four-terminal architecture on top of semi-insulating Fe: InP (001) wafers, optical orientation is separated from electrical detection. Spin filt ...

Game-theoretic Models of Web Credibility

Karl Aberer

Research on Web credibility assessment can significantly benefit from new models that are better suited for evaluation and study of adversary strategies. Currently employed models lack several important aspects, such as the explicit modeling of Web content ...

Corporate investment and financing under asymmetric information

Erwan Morellec, Norman Schuerhoff

We develop a dynamic model of corporate investment and financing decisions in which corporate insiders have superior information about the firm's growth prospects. We show that firms with positive private information can credibly signal their type to outsi ...

The evolution of communication in robot societies

Sara Mitri

Communication is fundamental to life on earth. All social organisms, from bacteria to humans, use communicative signals to coordinate their behaviors with members of their own and other species. Despite its key role in social organization, many questions r ...

Weak signals as a flexible framing space for enhanced management and decision-making

Pierre Rossel

This paper revisits theories of weak signal analysis using the concepts of 'framing' and 'meta-framing' to provide an enriched methodological environment for management and decision-making in turbulent contexts. This attempt takes place within the effort t ...
