Ecohydrological and Metacommunity Studies of Proliferative Kidney Disease Spread in Freshwater Salmonid Fish

Luca Carraro

Proliferative kidney disease (PKD) is a high-mortality pathology affecting freshwater salmonid populations in Europe and North America. Its causative agent, the myxozoan Tetracapsuloides bryosalmonae, has a complex life-cycle exploiting freshwater bryozoan ...

Tunable insertion of multiple lines into a Kerr frequency comb using electro-optical modulators

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Yan Yan, Lin Zhang, Ahmad Fallahpour, Amirhossein Mohajerin Ariaei, Cong Liu

We experimentally insert a flexible number of electro-optical (EO) comb lines into a Kerr frequency comb via EO modulation and demonstrate the use of combined Kerr and EO combs as light sources in coherent communications. The number of EO lines inserted in ...

Patient-derived xenograft (PDX) models in basic and translational breast cancer research

Cathrin Brisken, Georgios Sflomos, Valentina Scabia

Patient-derived xenograft (PDX) models of a growing spectrum of cancers are rapidly supplanting long-established traditional cell lines as preferred models for conducting basic and translational preclinical research. In breast cancer, to complement the now ...

Imaging blood cells through scattering biological tissue using speckle scanning microscopy

Demetri Psaltis, Ye Pu, Ye Pu, Xin Yang

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller ...

Bandwidth and repetition rate programmable Nyquist sinc-shaped pulse train source based on intensity modulators and four-wave mixing

Camille Sophie Brès, Mohammad Amin Shoaie, Steevy Joyce Cordette

We propose and experimentally demonstrate an all-optical Nyquist sinc-shaped pulse train source based on intensity modulation and four-wave mixing. The proposed scheme allows for the tunability of the bandwidth and the full flexibility of the repetition ra ...

Monte Carlo simulation of the field back-scattered from rough surfaces

Christian Depeursinge, Yves Delacrétaz, Stéphane Chamot

A novel approach for the simulation of the field back-scattered from a rough surface is presented. It takes into account polarization and multiple scattering events on the surface, as well as diffraction effects. The validity and usefulness of this simulat ...

Hydrologic controls and anthropogenic drivers of the zebra mussel invasion of the Mississippi-Missouri river system

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

We propose a novel ecohydrological model for the invasion of inland waters by the zebra mussel Dreissena polymorpha and test it against field data gathered within the Mississippi-Missouri river system in North America. This biological invasion poses major ...

Inline holographic coherent anti-Stokes Raman microscopy

Demetri Psaltis, Ho Ling Li, Kun Shi

We demonstrate a simple approach for inline holographic coherent anti-Stokes Raman scattering (CARS) microscopy, in which a layer of uniform nonlinear medium is placed in front of a specimen to be imaged. The reference wave created by four-wave mixing in t ...

Imaging through turbid layers by scanning the phase conjugated second harmonic radiation from a nanoparticle

Demetri Psaltis, Ye Pu, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Grégoire Pierre Jean Laporte

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same r ...

Stochastic Optimization of Sailing Trajectories in an America's Cup Race

Frédéric Dumas

The main objective of the thesis is the study and the determination of an optimal navigation strategy, for a sailboat in an America's Cup race, by methods of stochastic optimization. Such methods are appropriate because the sailing team expects the wind to ...
