A Fully Dynamic Universal Accumulator

A dynamic universal accumulator is an accumulator that allows one to efficiently compute both membership and nonmembership witnesses in a dynamic way. It was first defined and instantiated by Li et al., based on the Strong RSA problem, building on the dyna ...

Aqueous Fabrication of pH-Gated, Polymer-Brush-Modified Alumina Hybrid Membranes

Harm-Anton Klok, Caroline Sugnaux

In this Article, we studied the surface immobilization of five organic-acid-modified atom-transfer radical polymerization (ATRP) initiators based on salicylic acid, catechol, phthalic acid, and m- and p-benzoic add on alumina, and we also investigated the ...

Field-effect-based chemical sensing using nanowire-nanoparticle hybrids: The ion-sensitive metal-semiconductor field-effect transistor

Klaus Kern, Kannan Balasubramanian, Vivek Pachauri

A new class of nanoscale devices called ion-sensitive metal-semiconductor field-effect transistors (nano-IS-MESFET) for sensing applications is reported. Nanoparticle-nanowire hybrids with active metal-semiconductor regions are operated as ion-sensitive fi ...

A Sub 100μW UWB Sensor-Node Powered by a Piezoelectric Vibration Harvester

Nico de Rooij, Danick Briand, Pierre-André Farine, Cyril Botteron, Pattanaphong Janphuang, Christian Robert, Gabriele Tasselli

Piezoelectric harvesters are considered an alternative power source for applications that can support low to medium data rate transmissions in wireless sensor networks where ambient vibrations can provide microwatts to milliwatts of power. In this paper, w ...

On the limiting behavior of distributed optimization strategies

Ali H. Sayed

Motivated by recent developments in the context of adaptation over networks, this work establishes useful results about the limiting global behavior of diffusion and consensus strategies for the solution of distributed optimization problems. It is known th ...

Electrochemical Push–Pull Scanner with Mass Spectrometry Detection

Hubert Girault, Andreas Stephan Lesch, Liang Qiao, Fernando Cortes Salazar, Dmitry Momotenko, Gunther Wittstock

This manuscript presents a push-pull electrochem. scanner able to image reactivity of initially dry surfaces by scanning electrochem. microscopy (SECM) and to probe mols. present or generated at the surface by mass spectrometry (MS). The proof-of-concept i ...

The impossibility of boosting distributed service resilience

Rachid Guerraoui

We study f -resilient services, which are guaranteed to operate as long as no more than f of the associated processes fail. We prove three theorems asserting the impossibility of boosting the resilience of such services. Our ﬁrst theorem allows any connect ...

Oscillator-based assistance of cyclical movements: model-based and model-free approaches

Auke Ijspeert, Jesse van den Kieboom, Renaud Ronsse

In this article, we propose a new method for providing assistance during cyclical movements. This method is trajectory-free, in the sense that it provides user assistance irrespective of the performed movement, and requires no other sensing than the assist ...

Head Motion Detection Using FID Navigators

Rolf Gruetter, Tobias Kober, José Pedro Rebelo Ferreira Marques

This work explores a concept for motion detection in brain MR examinations using high channel-count RF coil arrays. It applies ultrashort (< 100 mu sec) free induction decay signals, making use of the knowledge that motion induces variations in these signa ...
