The Alternative Cultural Life of Lisbon: two case-studies

Letícia Cabeçadas Do Carmo

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 ...

Nonlinear plasmonics of metallic heptamers

Olivier Martin, Krishnan Thyagarajan, Simon Rivier

Second-harmonic generation (SHG) from centrosymmetric nanostructures originating from the breaking of inversion symmetry at their surfaces is a well-known phenomenon and is extensively used as a surface probe in nonlinear optical microscopy. In recent year ...

Like a Bolt from the Blue: Phthalocyanines in Biomedical Optics

Hubert van den Bergh

The purpose of this review is to compile preclinical and clinical results on phthalocyanines (Pcs) as photosensitizers (PS) for Photodynamic Therapy (PDT) and contrast agents for fluorescence imaging. Indeed, Pcs are excellent candidates in these fields du ...

Motion of Spin Polariton Bullets in Semiconductor Microcavities

Timothy Chi Hin Liew

The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...

On the Brauer group of diagonal quartic surfaces

Evis Ieronymou

We obtain an easy sufficient condition for the Brauer group of a diagonal quartic surface D over Q to be algebraic. We also give an upper bound for the order of the quotient of the Brauer group of D by the image of the Brauer group of Q. The proof is based ...

Status of the EU 170 GHz/2 MW/CW Coaxial Cavity Gyrotron for ITER: The Dummy Gun Experiment

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Ioannis Pagonakis

A mock-up gun has been manufactured as exact replica of the refurbishment first prototype EU 170 GHz/2MW/CW coaxial cavity gyrotron, but without emitter ring in order to validate the voltage standoff stability. The experimental results of the mock-up gun t ...

Digital holography for second harmonic microscopy: application to 3D-tracking of nanoparticles

Christian Depeursinge, Etienne Shaffer

Retrieval of the amplitude and phase of electromagnetic waves made digital holographic microscopy (DHM) capable of revealing morphological details at ultrahigh resolution in the order of a few nanometers only and precisely measuring the refractive index ac ...

Higher order coherence of exciton-polariton condensates

Paolo Schwendimann, Antonio Quattropani

The second- and third-order coherence functions g((n))(0) (n= 2 and 3) of an exciton-polariton condensate are measured and compared to the theory. Contrary to an ideal photon laser, deviation from unity in the second- and third-order coherence functions is ...

Performance evaluation of two state of the art DVC codecs

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

The performance of existing DVC codecs is still lacking relative to that of H.264 and work is being carried out in order to close this gap. The authors of this paper have been and still are involved in the development of two DVC codecs respectively, the pe ...

Order-adaptive frequency trackers for direct-to-Earth Mars communications

Ali H. Sayed

During the entry, descent and landing phase (EDL) of the missions to Mars, the spacecraft's high dynamics imprints severe Doppler swings on the signals transmitted via the direct-to-Earth (DTE) channel. In order to recover the data that record the mission ...
