‘‘What an Eccentric Performance" : Storytelling in Online Let's Plays
2019
In this article, I examine the phenomenon called Let’s Play (LP) and conduct a narrative analysis on two LPs made of Sierra Entertainment’s Phantasmagoria games. The LPs tell viewers a story different from the one told in the games, that is, they tell the story of the player rather than that of the game. In that story, the experience of playing a video game is revealed to the audience. This story would be hidden without the player-narrators know as LPs around the world. I conduct my analysis by describing seven different narrative elements that form the narration of a LP and explain how these elements together form this story of the player. peerReviewed
What Drives Negative Electronic Word-of-Mouth Online?
2018
The online environment has highlighted the role of negative experiences and emotions by enabling fast and widespread publicity. Recent research has introduced both word-of-mouth and engagement as central concepts relating to negative communication online. In the field of public relations, the previous literature has mostly addressed negative engagement through individual topics such as reputation and crisis communication, but there has been little attention to the different forms it takes. By utilizing recent literature on word-of-mouth (WOM), negative word-of-mouth (nWOM), and electronic word-of-mouth (eWOM) communication, we propose negative electronic word-of-mouth (neWOM) as a rising ph…
Noise effect in a FitzHugh-Nagumo circuit driven by a bichromatic signal
2013
We analyze the response of a nonlinear circuit exactly ruled by the FitzHugh-Nagumo equations. This circuit is submitted to a bichromatic signal including a high frequency and a low frequency. In absence of noise, we show that for an appropriate amplitude of the high frequency driving, the response of the circuit estimated at the low frequency can be optimized via the phenomenon of vibrational resonance. Next, we show that under certain conditions, noise can contribute to the effect of vibrational resonance. Colored noise is also considered. Our experimental results are confirmed by a numerical analysis.

Increasing the Astrophysical Reach of the Advanced Virgo Detector via the Application of Squeezed Vacuum States of Light
2019
Current interferometric gravitational-wave detectors are limited by quantum noise over a wide range of their measurement bandwidth. One method to overcome the quantum limit is the injection of squeezed vacuum states of light into the interferometer's dark port. Here, we report on the successful application of this quantum technology to improve the shot noise limited sensitivity of the Advanced Virgo gravitational-wave detector. A sensitivity enhancement of up to 3.2±0.1 dB beyond the shot noise limit is achieved. This nonclassical improvement corresponds to a 5%-8% increase of the binary neutron star horizon. The squeezing injection was fully automated and over the first 5 months of the thi…
Individual differences in the new literacies of online research and comprehension

The many faces of online community : Images and imaginings of togetherness on Imgur
2018
This article discusses the meaning and function of “community” as a discourse on the image-sharing website Imgur. The analysis shows that the community term has many meanings and serves as a shorthand for a wide variety of social practices, and these meanings are shaped by the experiences of social action leading to the use of the term. Based on ethnographic data, nexus analysis provides an understanding of how the interactions related to community on the site come to take place the way they do. In conceiving of these interactions as mediated discourse, the article provides a fresh approach to the long-established academic discussion on the definition of community, suggesting a new concepti…
Noise effect in a sine-Gordon Lattice
2013
International audience; This paper is devoted to the influence of internal noise in a sine-Gordon chain exhibiting the well known nonlinear supratransmission phenomenon. It is shown that spatiotemporal noise can trigger breather modes with a given probability in a range of parameters where they do not occur without noise. A frequency analysis is carried out to quantify the degree of coherence of the emitted breather. It is shown that there exists an appropriate amount of noise which ensures the existence of breather modes with the best coherence.
Inference of proto-neutron star properties from gravitational-wave data in core-collapse supernovae
2021
The eventual detection of gravitational waves from core-collapse supernovae (CCSN) will help improve our current understanding of the explosion mechanism of massive stars. The stochastic nature of the late post-bounce gravitational wave signal due to the non-linear dynamics of the matter involved and the large number of degrees of freedom of the phenomenon make the source parameter inference problem very challenging. In this paper we take a step towards that goal and present a parameter estimation approach which is based on the gravitational waves associated with oscillations of proto-neutron stars (PNS). Numerical simulations of CCSN have shown that buoyancy-driven g-modes are responsible …
Ghost stochastic resonance in FitzHugh–Nagumo circuit
2014
International audience; The response of a neural circuit submitted to a bi-chromatic stimulus and corrupted by noise is investigated. In the presence of noise, when the spike firing of the circuit is analysed, a frequency not present at the circuit input appears. For a given range of noise intensities, it is shown that this ghost frequency is almost exclusively present in the interspike interval distribution. This phenomenon is for the first time shown experimentally in a FitzHugh-Nagumo circuit.
