Multiplicative chaos of the Brownian loop soup

Antoine Pierre François Jego, Titus Lupu

We construct a measure on the thick points of a Brownian loop soup in a bounded domain D

D

of the plane with given intensity theta>0

A Variable Stiffness Magnetic Catheter Made of a Conductive Phase-Change Polymer for Minimally Invasive Surgery

Dario Floreano, Yegor Piskarev, Jun Shintake

Variable stiffness (VS) is an important feature that significantly enhances the dexterity of magnetic catheters used in minimally invasive surgeries. Existing magnetic catheters with VS consist of sensors, heaters, and tubular structures filled with low me ...

Chirok: a post-refinement tool to analyse absolute structure

Philip Pattison

Chirok is software for a post-refinement test of the absolute structure. The software allows a user to calculate a distribution of the measure of chirality based on intensity quotients and linked to the Flack parameter. The distribution is fitted by a set ...

Intermodal measurements in few-mode fibers with phase- sensitive OTDR

Luc Thévenaz, Zhisheng Yang, Alejandro Dominguez Lopez

We experimentally verify the possibility of measuring the difference in effective refractive index between higher-order-modes using a phase-sensitive OTDR, indicating that it is possible to measure the average difference over long fiber spans. ...

Continuity Of Multimarginal Optimal Transport With Repulsive Cost

Maria Colombo, Federico Stra

We provide sharp conditions for the finiteness and the continuity of multimarginal optimal transport with repulsive cost, expressed in terms of a suitable concentration property of the measure. To achieve this result, we analyze the Kantorovich potentials ...

Are Photonic Nanojets Achromatic?

Toralf Scharf, Myun Sik Kim, Michail Symeonidis

In this work we study the evolution of the photonic nanojet (PNJ) phenomenon as the ratio of the sphere's diameter over the illumination wavelength changes, for microspheres with diameters from 2 mu m to 100 mu m. We measure the focal point position by usi ...

Quantifying Fano properties in self-assembled metamaterials

Olivier Martin

Fano resonances in metamaterials can be explained by the coupling between different modes sustained by the meta-atom. While the associated spectral features are usually quite easy to identify for top-down metamaterials, thanks to the deterministic arrangem ...

A Variable Stiffness Catheter Controlled with an External Magnetic Field

Dario Floreano, Alice Tonazzini

Remote magnetic navigation of catheters is a technique used to perform radiofrequency ablation of heart tissue in order to treat cardiac arrhythmias. The flexible magnetic catheters used in this context are in some cases not sufficiently dexterous to navig ...

Thin films for Healthcare Acquired Infections (HAIs) prevention

Sami Rtimi

This thesis addresses the preparation of antibacterial surfaces for hospital facilities taking biomedical thin polymer films, textiles and catheter as probes. Magnetron sputtering is used to apply the coatings leading to fast bacterial inactivation in the ...

Intra-Arterial Drug and Light Delivery for Photodynamic Therapy Using Visudyne (R): Implication for Atherosclerotic Plaque Treatment

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Manish Jain

Photodynamic therapy (PDT), which is based on the activation of photosensitizers with light, can be used to reduce plaque burden. We hypothesized that intra-arterial photosensitizer administration and photo-activation will lead to high and rapid accumulati ...
