Study of impurity ion transport using charge exchange spectroscopy on TCV

Filippo Bagnato

The study of impurity transport in fusion plasmas has gained interest over the years due to its implication with tokamak performances. In TCV (Tokamak à Configuration Variable), as in many other facilities, impurity ions can be studied through the CXRS (Ch ...

Analysis-aware defeaturing of complex geometries

Pablo Antolin Sanchez, Ondine Gabrielle Chanon

Local modifications of a computational domain are often performed in order to simplify the meshing process and to reduce computational costs and memory requirements. However, removing geometrical features of a domain often introduces a non-negligible error ...

A Performative Threshold Between Teaching Research and Practice. Atlas Poliphilo as Scaffold

Dieter Dietz, Julien Lafontaine Carboni, Aurélie Dupuis, Darío Negueruela Del Castillo

Hunches allow us to navigate in a trans-scalar world. Without them, teachers, researchers and practitioners would be left aimless. Hunches relate to the embodied and synthetic nature of the knowledge we produce, but also to its unfolding. Instead of denyin ...

Anhydrous Conditions Enable the Catalyst-Free Carboxylation of Aromatic Alkynes with CO2 under Mild Conditions

Paul Joseph Dyson, Marinella Mazzanti, Felix Daniel Bobbink, Davide Toniolo

The direct carboxylation of aromatic alkynes with CO2, a cheap and widely available C1 source, is the most attractive method for the synthesis of carboxylic acids. Here we show that direct carboxylation of terminal alkynes can be simply performed in near-q ...

Virtual Vehicle-Based Cooperative Maneuver Planning for Connected Automated Vehicles at Single-Lane Roundabouts

Denis Gillet, Ezequiel González Debada

This paper presents a distributed maneuver planner for connected automated vehicles (CAVs) built upon the idea of CAVs being able to explicitly share their intentions by creating virtual vehicles (Us) on the targeted traffic stream. Specifically, this work ...

Entrainment of Voluntary Movement to Undetected Auditory Regularities

Olaf Blanke, Leila Cammoun, Aaron Schurger, Nathan Quentin Faivre

In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked ...

Efficient Electrochemical Production of Peroxodicarbonate Applying DIACHEM (R) Diamond Electrodes

Christos Comninellis

The electrochemical synthesis of peroxodicarbonate was performed on boron-doped DIACHEM((R)) diamond anodes (BDD). The influence of various parameters was studied and promising conditions were determined in an undivided cell design by CONDIAS GmbH. The bes ...

Exploiting sequence information for text-dependent Speaker Verification

Petr Motlicek, Subhadeep Dey

Model-based approaches to Speaker Verification (SV), such as Joint Factor Analysis (JFA), i-vector and relevance Maximum-a-Posteriori (MAP), have shown to provide state-of-the-art performance for text-dependent systems with fixed phrases. The performance o ...

Back to the Source: an Online Approach for Sensor Placement and Source Localization

Patrick Thiran, Laura Elisa Celis, Brunella Marta Spinelli

Source localization, the act of finding the originator of a disease or rumor in a network, has become an important problem in sociology and epidemiology. The localization is done using the infection state and time of infection of a few designated sensor no ...

Cyber-attack on Packet-Based Time Synchronization Protocols: the Undetectable Delay Box

Jean-Yves Le Boudec, Aswin Suresh, Sergio Barreto Andrade

We present a cyber-attack on packet-based time synchronization protocols (PBTSP) with high-accuracy requirements. The cyber-attack is undetectable from the PBTSP's perspective and exploits a vulnerability that is in the nature of all PBTSPs. It can be succ ...

Timing jitter studies of the SwissFEL Test Injector drive laser

Christoph Peter Hauri, Thomas Schietinger

To produce short X-ray pulses for SwissFEL(1), it is necessary to compress the electron bunches by a factor of 300, down to sub-fs for the attosecond operational modes. To achieve stable EEL output accurate timing of the initial electron injection at the m ...

Synthesis of borasiloxane-based macrocycles by multicomponent condensation reactions in solution or in a ball mill

Rosario Scopelliti, Kay Severin, Albert Ruggi, Mirela Pascu

Large macrocycles containing imine and borasiloxane links are obtained in polycondensation reactions of 4-formylbenzeneboronic acid, t-Bu2Si(OH)2, and diamines. The multicomponent reactions can be performed in solution or – advantageously – by mechanochemi ...

ConDense: Managing Data in Community-driven Mobile Geosensor Networks

Karl Aberer, Dipanjan Chakraborty, Saket Sathe, Sebastian Cartier

Effectively managing the data generated by community-driven mobile geo-sensor networks is a new and challenging problem. One important step for managing and querying sensor network data is to create abstractions of the data in the form of models. These mod ...

Flux- and gradient-driven global gyrokinetic simulation of tokamak turbulence

Olivier Sauter, Laurent Villard, Stephan Brunner, Ben McMillan, Xavier Lapillonne

The Eulerian gyrokinetic turbulence code GENE has recently been extended to a full torus code. Moreover, it now provides Krook-type sources for gradient-driven simulations where the profiles are maintained on average as well as localized heat sources for a ...
