Renzo Piano: un architecte Ă l'Ă©coute de la Ville
L’idée selon laquelle le lieu est, pour l’architecte, la force vitale de l’édifice et que déchiffrer le lieu signifie en dégager
la puissance créative et l’insuffler au projet, est à la base de la méthode d’élaboration des projets que le génois Renzo
Piano a expérimentés et affinés dans les endroits les plus divers de la planète. Ainsi Central Saint Giles et The Shard
London Bridge matérialisent de manière explicite l’exceptionnelle subtilité qui guide l’architecte dans l’écoute de voix,
d’histoires, de couleurs, de parfums, d’émotions que Londres condense et exhale. Ce texte, tiré d’une conférence, offre
une lecture rapprochée de ces deux oeuvres si différentes, aussi insolites que splendides, les replaçant au sein de la
prodigalité créatrice d’un demi-siècle de projets de Piano, sénateur à vie de la République italienne.
Riassunto
L’idea per cui il luogo è, per l’architetto, la forza vitale dell’edificio e che decifrare il luogo significa sprigionare la
potenza creativa e infonderla al projetto è alla base del metodo progettuale che il genovese Renzo Piano ha sperimentato
e affinato nei luoghi piĂą diversi del pianetĂ . Il Central Saint Giles e il Shard London Bridge materializzano in termini
espliciti l’eccezionale sottigliezza dell’architetto alle tante voci, storie, colori, profumi, emozioni que Londra addensa
e traspira. Il testo, tratto da une conferenza, affronta la lettura ravvicinata di queste due opere tanto diverse, quanto
insolite e leggiadre, rapportandole alla prodigalitĂ creativa del mezzo secolo di progettazione di Piano, senatore a vita

Modeling the fake news challenge as a cross-level stance detection task
The 2017 Fake News Challenge Stage 1, a shared task for stance detection of news articles and claims pairs, has received a lot of attention in recent years [3]. The provided dataset is highly unbalanced, with a skewed distribution towards unrelated samples - that is, randomly generated pairs of news and claims belonging to different topics. This imbalance favored systems which performed particularly well in classifying those noisy samples, something which does not require a deep semantic understanding.
In this paper, we propose a simple architecture based on conditional encoding, carefully designed to model the internal structure of a news article and its relations with a claim. We demonstrate that our model, which only leverages information from word embeddings, can outperform a system based on a large number of hand-engineered features, which replicates one of the winning systems at the Fake News Challenge [6], in the stance detection of the related samples
PARISROC, a Photomultiplier Array Integrated Read Out Chip
PARISROC is a complete read out chip, in AMS SiGe 0.35 !m technology, for
photomultipliers array. It allows triggerless acquisition for next generation
neutrino experiments and it belongs to an R&D program funded by the French
national agency for research (ANR) called PMm2: ?Innovative electronics for
photodetectors array used in High Energy Physics and Astroparticles?
(ref.ANR-06-BLAN-0186). The ASIC (Application Specific Integrated Circuit)
integrates 16 independent and auto triggered channels with variable gain and
provides charge and time measurement by a Wilkinson ADC (Analog to Digital
Converter) and a 24-bit Counter. The charge measurement should be performed
from 1 up to 300 photo- electrons (p.e.) with a good linearity. The time
measurement allowed to a coarse time with a 24-bit counter at 10 MHz and a fine
time on a 100ns ramp to achieve a resolution of 1 ns. The ASIC sends out only
the relevant data through network cables to the central data storage. This
paper describes the front-end electronics ASIC called PARISROC.Comment: IEEE Nuclear Science Symposium an Medical Imaging Conference (2009

Geometric parametric instability in periodically modulated graded-index multimode fibers
International audienceWe present a theoretical and numerical study of light propagation in graded-index (GRIN) mul-timode fibers where the core diameter has been periodically modulated along the propagation direction. The additional degree of freedom represented by the modulation permits to modify the intrinsic spatiotemporal dynamics which appears in multimode fibers. More precisely, we show that modulating the core diameter at a periodicity close to the self-imaging distance allows to induce a Moiré-like pattern, which modifies the geometric parametric instability gain observed in homogeneous GRIN fibers
Will-they-won't-they: A very large dataset for stance detection on twitter
We present a new challenging stance detection dataset, called Will-They-Won’t-They (WT--WT), which contains 51,284 tweets in English, making it by far the largest available dataset of the type. All the annotations are carried out by experts; therefore, the dataset constitutes a high-quality and reliable benchmark for future research in stance detection. Our experiments with a wide range of recent state-of-the-art stance detection systems show that the dataset poses a strong challenge to existing models in this domain.Keynes Fund, Cambridg
Euclid: Superluminous supernovae in the Deep Survey
Context. In the last decade, astronomers have found a new type of supernova called superluminous supernovae (SLSNe) due to their high peak luminosity and long light-curves. These hydrogen-free explosions (SLSNe-I) can be seen to z ~ 4 and therefore, offer the possibility of probing the distant Universe.
Aims. We aim to investigate the possibility of detecting SLSNe-I using ESA’s Euclid satellite, scheduled for launch in 2020. In particular, we study the Euclid Deep Survey (EDS) which will provide a unique combination of area, depth and cadence over the mission.
Methods. We estimated the redshift distribution of Euclid SLSNe-I using the latest information on their rates and spectral energy distribution, as well as known Euclid instrument and survey parameters, including the cadence and depth of the EDS. To estimate the uncertainties, we calculated their distribution with two different set-ups, namely optimistic and pessimistic, adopting different star formation densities and rates. We also applied a standardization method to the peak magnitudes to create a simulated Hubble diagram to explore possible cosmological constraints.
Results. We show that Euclid should detect approximately 140 high-quality SLSNe-I to z ~ 3.5 over the first five years of the mission (with an additional 70 if we lower our photometric classification criteria). This sample could revolutionize the study of SLSNe-I at z > 1 and open up their use as probes of star-formation rates, galaxy populations, the interstellar and intergalactic medium. In addition, a sample of such SLSNe-I could improve constraints on a time-dependent dark energy equation-of-state, namely w(a), when combined with local SLSNe-I and the expected SN Ia sample from the Dark Energy Survey.
Conclusions. We show that Euclid will observe hundreds of SLSNe-I for free. These luminous transients will be in the Euclid data-stream and we should prepare now to identify them as they offer a new probe of the high-redshift Universe for both astrophysics and cosmology.Acknowledgements.
