The Alternative Cultural Life of Lisbon: two case-studies

In a dramatic crisis context, Lisbon reveals itself as an attractive and dynamic city of alternative bustling creativity. Trying to understand this paradox, I analyse two successful “alternative cultural spaces”: Lx Factory and Pensão Amor. Urban strategie ...

Fast Detection Of Cells Using A Continuously Scalable Mexican-Hat-Like Template

Michaël Unser, Daniel Sage, Kunal Narayan Chaudhury

We propose a fast algorithm for the detection of cells in fluorescence images. The algorithm, which estimates the number of cells and their respective centers and radii, relies on the fast computation of intensity-based correlations between the cells and a ...

Fast Space-Variant Elliptical Filtering Using Box Splines

Michaël Unser, Kunal Narayan Chaudhury

The efficient realization of linear space-variant (non-convolution) filters is a challenging computational problem in image processing. In this paper, we demonstrate that it is possible to filter an image with a Gaussian-like elliptic window of varying siz ...

Small Molecule Based Approaches to Inhibit Macrophage Migration Inhibitory Factor (MIF) Activities and Elucidate its Role in Health and Disease

Hajer Ouertatani-Sakouhi

Macrophage migration inhibitory factor (MIF) is a major mediator in innate immunity and inflammation and a potential therapeutic target in multiple inflammatory, infectious and autoimmune diseases including cancer. Current therapeutic strategies for target ...

Barium titanate nanoparticles used as second harmonic radiation imaging probes for cell imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

Luminescent markers play a key role in imaging techniques for life science since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocry ...

Assessment of successful experiments and limitations of phytotechnologies: contaminant uptake, detoxification and sequestration, and consequences for food safety

Jean-Paul Schwitzguebel

The term "phytotechnologies" refers to the application of science and engineering to provide solutions involving plants, including phytoremediation options using plants and associated microbes to remediate environmental compartments contaminated by trace e ...

Harmonic holographic microscopy with circularly polarized excitation

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We have developed a luminescent marker using the second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocrystals. These nanoparticles are attractive due to their stable, non-saturating and coherent signal with a femtosecond-scale response time ...

Harmonic holography for three-dimensional cellular imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

Luminescent markers play a key role in imaging techniques for life sciences since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocr ...

Electron localization by a donor in the vicinity of a basal stacking fault in GaN

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Pierre Michel Corfdir, Jelena Ristic

We study the effects of the vicinity between a shallow donor nucleus and an I1-type basal stacking fault (BSF) in GaN. We propose a numerical calculation, in the “effective potential” formalism, of energies and envelope functions of electrons submitted to ...
