Fractal Modeling of Polymer Plasma Laser Ablation, Plasma Plume Tsallis Entropy and Its q-Statistics Interpretation, Part I: Theory

Polymer plasma produced by laser ablation is investigated in a theoretical manner. In relation to the fact that the charge carrier circulation is assumed to take place on fractal curves, the so-called fractality type, electrical charge transport can be res ...

R&D offshoring and home industry productivity

Gaétan Jean A de Rassenfosse

Offshoring research and development (R&D) commonly invokes concerns regarding the loss of high value jobs and a hollowing out of technological capabilities, but it can also benefit domestic firms by enabling them to tap into the global technological fronti ...

Evaluation of the muscular activity duration in shoulders with rotator cuff tear using inertial sensors and electromyography

Kamiar Aminian, Alain Farron, Cyntia Duc

Shoulder disorders, including rotator cuff tears, affect the shoulder function and result in adapted muscle activation. Although these adaptations have been studied in controlled conditions, free-living activities have not been investigated. Based on the k ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIII. Time delays and 9-yr optical monitoring of the lensed quasar RX J1131-1231

Frédéric Courbin, Georges Meylan, Malte Tewes, Nicolas Cantale

We present the results from nine years of optically monitoring the gravitationally lensed z(QSO) = 0.658 quasar RX J1131-1231. The R-band light curves of the four individual images of the quasar were obtained using deconvolution photometry for a total of 7 ...

The RNA degradosome: life in the fast lane of adaptive molecular evolution

In Escherichia coli, the multi-enzyme RNA degradosome contributes to the global, posttranscriptional regulation of gene expression. The degradosome components are recognized through natively unstructured "microdomains" comprising as few as 15-40 amino acid ...

Full-field laser Doppler perfusion imaging and monitoring with an intelligent CMOS camera

Theo Lasser

A system for full-field laser Doppler blood flow imaging has been developed and tested on biomedical samples. The new imaging system allows 2D flow maps or monitoring flux signals to be obtained from a plurality of measured points simultaneously by using a ...

Multiple scattering in optical coherence tomography. I. Investigation and modeling

Theo Lasser, Boris Clément Karamata, Marcel Leutenegger, Stéphane Bourquin, Markus Laubscher

We present a new model of optical coherence tomography (OCT) taking into account multiple scattering. A theoretical analysis and experimental investigation reveals that in OCT, despite multiple scattering, the field backscattered from the sample is general ...

Capteurs et algorithmes pour la localisation autonome en mode pédestre

Quentin Ladetto

The challenge of knowing one's position in a precise and reliable way, at any time, with and without reception of satellite signals, represents an area fairly explored for the navigation of vehicles. To widen this service to the pedestrians requires a diff ...

Protection Interoperability for WDM Optical Networks

Jean-Yves Le Boudec, Olivier Crochat

The failure of a single optical link or node in a Wavelength Division Multiplexing (WDM) network may cause the simultaneous failure of several optical channels. In some cases, this simultaneity may make it impossible for the higher level (SONET or IP) to r ...
