Case study – Delta restoration at a steep river mouth

Anton Schleiss, Giovanni De Cesare, Stéphanie Joëlle André, Stéphane Christian Olivier Terrier

The mouth of the Baye de Clarens torrent in Switzerland is currently constrained by lateral training walls, sequent sills and a bridge with a low hydraulic capacity. Due to a bed load trap upstream, few sediments reach the mouth. To improve flood protectio ...

Stem cells of stratified epithelia : a generic stem cell?

Daniel-Alexandre Littman

Squamous stratified epithelia tissues are self-renewing, which quality implies the existence of stem cells. In skin the presence of bona fide multipotent stem cells has been demonstrated by long-term, serial grafting assays. We isolated, cultivated and exp ...

Visual feature analysis for audio-visual speech recognition

Ivana Arsic de Heras Ciechomska

Humans perceive their surrounding environment in a multimodal manner by using multi-sensory inputs combined in a coordinated way. Various studies in psychology and cognitive science indicate the multimodal nature of human speech production and perception. ...

Analysis of Multimodal Sequences Using Geometric Video Representations

Pierre Vandergheynst, Gianluca Monaci, Oscar Divorra Escoda

This paper presents a novel method to correlate audio and visual data generated by the same physical phenomenon, based on sparse geometric representation of video sequences. The video signal is modeled as a sum of geometric primitives evolving through time ...

Glial cell line-derived neurotrophic factor released by synthetic guidance channels promotes facial nerve regeneration in the rat

Patrick Aebischer, Nicolas Bouche

Regeneration of the human facial nerve after lesion is often limited, leading to severe functional impairments, in particular when repair is delayed for several months, when cross-facial nerve grafts have to be performed, or in elderly patients. To improve ...

Pharmacokinetics and pharmacodynamics of tetra(m-hydroxyphenyl)chlorin in the hamster cheek pouch tumor model: comparison with clinical measurements

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

The pharmacokinetics (PK) of the photosensitizer tetra(m-hydroxyphenyl)chlorin (mTHPC) was measured by optical fiber-based light-induced fluorescence spectroscopy (LIFS) in the normal and tumoral cheek pouch mucosa of 29 Golden Syrian hamsters with chem. i ...

Stability of the fluorescence measurement of Foscan in the normal human oral cavity as an indicator of its content in early cancers of the esophagus and the bronchi

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

Photodynamic therapy (PDT) with Foscan (mTHPC) is used to cure early cancers of the esophagus or the tracheobronchial tree. However, fixed PDT parameters (drug dose, light dose, etc.) do not permit an accurate prediction of the tissue damage. Large interpa ...

Clinical pharmacokinetic studies of photofrin by fluorescence spectroscopy in the oral cavity, the esophagus, and the bronchi

Hubert van den Bergh, Georges Wagnières

Background. To optimize photodynamic therapy (PDT) and photodetection of cancer, two important variables that must be considered are the uptake of the dye and the dye contrast between normal and neoplastic tissue after injection. Methods. To study these va ...
