Optically pumped Cs magnetometers enabling a high-sensitivity search for the neutron electric dipole moment
2020
An array of 16 laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 2016. It was deployed to measure the gradients of the experiment's magnetic field and to monitor their temporal evolution. The originality of the array lies in its compact design, in which a single near-infrared diode laser drives all magnetometers that are located in a high-vacuum chamber, with a selection of the sensors mounted on a high-voltage electrode. We describe details of the Cs sensors' construction and modes of operation, emphasizing the accuracy and sensitivity of the magnetic-field readout. We present two app…
First measurement of proton's charge form factor at very low $Q^2$ with initial state radiation
2017
We report on a new experimental method based on initial-state radiation (ISR) in e-p scattering, in which the radiative tail of the elastic e-p peak contains information on the proton charge form factor ($G_E^p$) at extremely small $Q^2$. The ISR technique was validated in a dedicated experiment using the spectrometers of the A1-Collaboration at the Mainz Microtron (MAMI). This provided first measurements of $G_E^p$ for $0.001\leq Q^2\leq 0.004 (GeV/c)^2$.
L'exposition photographique de rue. Le rapport à l'œuvre, entre relation et interaction
2009
In the very particular context (press crisis, digital revolution, photojournalism shifting towards art market), photographic exhibitions have been organized in the street, these last years. How does it build the relationship to the creation ? This article shows that this relationship comes into being gradually on the inter subjective relations ; from relationship (subject / object connection), the esthetic experience changes into interaction in the sense of the symbolic interactionism (complex process where intertwines perceptions, interpretations, mutual adaptations between the subjects themselves and between subjects and objects). The study, result of a direct observation, takes place in …
Using eye-movement modelling examples to improve critical reading of multiple webpages on a conflicting topic
2022
This project investigates the effects of an EMME intervention on undergraduates' sourcing when reading conflicting multiple texts on the Internet. Dependent variables: eye-movements on SERP, webs header, texts authors, and texts; use of source information in summaries; ideas from texts in summaries.
Chemokine axes and inflammatory status in Metabolic Syndrome. Effect of PCSK9 inhibitors in the systemic inflammation associated to Familial Hypercho…
2019
Metabolic syndrome (MS) is a metabolic disorder characterized by a cluster of cardiovascular risk factors and its prevalence remains increasing in Western world. It is associated to low-grade systemic inflammation, a key driver of premature atherosclerosis and the major cause of cardiovascular disease (CVD). Given that CXCL16/CXCR6, CX3CL1/CX3CR1 and CCL2/CCR2 axes have been implicated in the development of CVD, we investigated the role of these axes in leukocyte adhesion to the dysfunctional arterial endothelium in a MS model. We also performed a comprehensive analysis of different cellular and soluble immune players in patients with MS. When compared with the controls, MS patients present…
"I use it correctly!": The use of ICTs among Italian grandmothers in a generational perspective
2018
In this project, we investigated the role played by digital media and information and communication technologies (ICTs) in building intergenerational and intragenerational relations for grandparents. Specifically, we investigated the possible relationships between grandmothers, children, and grandchildren, with the aim of understanding the dynamics of intergenerational exchanges and how grandmothers experience the use of the Internet as a tool to facilitate communication with family members. The research shows that the reflections regarding the role of the Internet among elderly people are often linked to a generational identity and generational belonging and involve constant comparison wit…
Emulating the Effects of Radiation-Induced Soft-Errors for the Reliability Assessment of Neural Networks
2021
International audience; Convolutional Neural Networks (CNNs) are currently one of the most widely used predictive models in machine learning. Recent studies have demonstrated that hardware faults induced by radiation fields, including cosmic rays, may significantly impact the CNN inference leading to wrong predictions. Therefore, ensuring the reliability of CNNs is crucial, especially for safety-critical systems. In the literature, several works propose reliability assessments of CNNs mainly based on statistically injected faults. This work presents a software emulator capable of injecting real faults retrieved from radiation tests. Specifically, from the device characterisation of a DRAM m…
At the Interface of National and Transnational: The Development of Finnish Policies against Domestic Violence in Terms of Gender Equality
2017
Although gender inequalities are the main social mechanisms behind the (re)production of domestic violence, policy responses to domestic violence as a gender-related problem vary at both the national and transnational levels. This article examines the interaction between national and transnational policies against domestic violence, focusing on how domestic violence is constructed as a gender-related problem in Finland, a Nordic welfare state that is often cited as a role model in gender equality. Using the conception of policies as historically changing and culturally specific discourses, this article offers an overview of the ways in which the perspective on domestic violence of the trans…
Non-linear interactions of femtosecond laser pulses with graphene : photo-oxidation, imaging and photodynamics
2017
This thesis presents a study focused on interactions of femtosecond laser pulses with graphene, a one atom thick carbon membrane. Graphene, which exhibits exceptional electronic and optoelectronic properties, could provide considerable advantage over current silicon-based electronics. Graphene alone, being semi-metal, is not sufficient for electronic applications, but requires modification. For this, a set of methods for modifying and measuring the properties of graphene was developed. With the perspective of making graphene a suitable component for electronics, optoelectronics or photonics, ultrashort laser pulses were used for drawing patterns on graphene. The procedure modifies graphene …
