Topology Optimization of an Electromagnet Manipulator for 3D Uniform Magnetic Field Generation

Yves Perriard, Adrien Jean-Michel Thabuis, Maribel Caceres Rivera, Xiaotao Ren

Magnetic manipulation is a method used for biomedical applications to remotely control micro-robots in a contactless manner. The electromagnet manipulator should control a magnetic field with 3 degrees of freedom inside a region of interest. In various cas ...

Metasurface-stabilized optical microcavities

Ileana-Cristina Benea-Chelmus

Cavities concentrate light and enhance its interaction with matter. Confining to microscopic volumes is necessary for many applications but space constraints in such cavities limit the design freedom. Here we demonstrate stable optical microcavities by cou ...

Belief Control Strategies for Interactions Over Weakly-Connected Graphs

Ali H. Sayed, Bicheng Ying

In diffusion social learning over weakly-connected graphs, it has been shown recently that influential agents shape the beliefs of non-influential agents. This paper analyzes this mechanism more closely and addresses two main questions. First, the article ...

IP Strategy and Use Of IP Protection Mechanisms Across Firm Size: An empirical investigation

Jana Thiel, Tilo Peters

In this paper we use data from the 2012 Innovation Strategy Survey (485 responses) to compare motives and choices with respect to IP strategy in firms with sizes ranging from micro to very large. Our results confirm significant differences across firm size ...

Simple ways to pace trains

Daniel Emery

As long as a train does not conflict with others trains, the energy consumption for traction can be minimized according to its times of departure, arrival, and passing through fixed points. However, when a conflict of itineraries is foreseen, pacing trains ...

Feedback Increases the Degrees of Freedom of Two Unicast Gaussian Networks

I-Hsiang Wang

In this paper we investigate the degrees of freedom of layered two unicast Gaussian networks with destination-to-source feedback. The feedback model allows the destinations to feedback their received signals to their respective sources perfectly. Based upo ...

Cavity Optomechanics with Whispering-Gallery Mode Optical Micro-Resonators

Tobias Kippenberg, Albert Schliesser

Parametric coupling of optical and mechanical degrees of freedom forms the basis of many ultra-sensitive measurements of both force and mechanical displacement. An optical cavity with a mechanically compliant boundary enhances the optomechanical interactio ...

Memories of the world of the mountains

Pascal Fua, Vincent Lepetit, Julien Pilet

This paper describes a particular book called Souvenirs du monde des montagnes, which draws its iconography from the history of a Swiss mountain family from 1910 to 1930. By simply dipping into the first few pages, the reader will be lost between real and ...

Scaling Laws for One and Two-Dimensional Random Wireless Networks in the Low Attenuation Regime

Olivier Lévêque, Ayfer Özgür Aydin

The capacity scaling of extended two-dimensional wireless networks is known in the high attenuation regime, i.e. when the power path loss exponent alpha is greater than 4. This has been accomplished by deriving information theoretic upper bounds for this r ...
