Novel Readout Circuit for Memristive Biosensors in Cancer Detection

Giovanni De Micheli, Sandro Carrara, Francesca Puppo, Ali Zaher

We present a novel circuit for the automated and quick characterization of an array of experimental memristive nanowires that are functionalized as biosensors. Successfully functionalized nanowires will express the concentration of target molecules by hyst ...

Evidence for TiON sputtered surfaces showing accelerated antibacterial activity under simulated solar irradiation

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi

New evidence is reported for TiON sputtered polyester surfaces activated by sunlight irradiation leading to the accelerated bacterial inactivation in the minute range. The absorption in Kubelka-Munk units of the TiON film was observed to be directly propor ...

Improved overlap speech diarization of meeting recordings using long-term conversational features

Hervé Bourlard, Sree Harsha Yella

Overlapping speech is a source of significant errors in speaker diarization of spontaneous meeting recordings. Recent works on speaker diarization have attempted to solve the problem of overlap detection using classifiers trained on acoustic and spatial fe ...

Randomized Extended Kaczmarz For Solving Least Squares

Nikolaos Freris

We present a randomized iterative algorithm that exponentially converges in the mean square to the minimum l(2)-norm least squares solution of a given linear system of equations. The expected number of arithmetic operations required to obtain an estimate o ...

Hydrophobic Meshes for Oil Spill Recovery Devices

Francesco Stellacci

Widespread use of petrochemicals often leads to accidental releases in aquatic environments, occasionally with disastrous results. We have developed a hydrophobic and oleophilic mesh that separates oil from water continuously in situ via capillary action, ...

Spatially resolved photocurrents in graphene nanoribbon devices

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Kannan Balasubramanian, Adarsh Singh Sagar, Thomas Dufaux

We present here a scanning photocurrent microscopy study of individual graphene nanoribbons, revealing pronounced photocurrent responses close to the nanoribbon/metal contacts. The magnitude of the corresponding photocurrent signal was found to be directly ...

Evaluation of Proportional and Discrete Shared Control Paradigms for Low Resolution User Inputs

José del Rocio Millán Ruiz, Robert Leeb, Tom Edward Carlson, Guillaume Monnard

For people with severe physical disabilities, low resolution input devices, such as buttons, sip and puff switches and brain–computer interfaces provide an opportunity to interact with the world. However, it can be difficult to control assistive technology ...

Reprint of: Weak epsilon-nets have basis of size O(1/epsilonlog(1/epsilon)) in any dimension

Given a set P of n points in R-d and epsilon > 0, we consider the problem of constructing weak E-nets for P. We show the following: pick a random sample Q of size O(1/epsilon log(1/epsilon)) from P. Then, with constant probability, a weak epsilon-net of P ...

The Effects of Fluid Elasticity on Grid Turbulence

Richard Vonlanthen

Experiments on grid turbulence are reported for pure water and dilute Polyox WSR 301 solutions. A novel passive grid, which consists of a square mesh grid with tethered spheres, has been developed to enhance the turbulence properties. In pure water the new ...

MEMS for space

Nico de Rooij, Danick Briand, Herbert Shea, Sebastian Gautsch, Wilfried Noell

Future space exploration will emphasize on cost effectiveness and highly focused mission objectives. Missions costs are directly proportional to its total weight, thus, the trend will be to replace bulky and heavy components of space carriers, communicatio ...
