The report presents the main issues, experimental details and first results of the project “Attitudes and language use of international students during their stay in Orléans: the example of discourse markers in L2” (ESLO-L2), realized at the host laboratory “Laboratoire Ligérien de Linguistique” (LLL) between March and July 2023. The aim of the project was to apply the methodology of the corpus of oral French “Enquête SocioLinguistique à Orléans” (ESLO), conceived as a “city’s sound portrait” to the group of foreign exchange students at the University of Orléans. The research interest of the project was aimed at the questions of how the students’ perception of the city, its inhabitants and the French language changes during the first 5-6 months of their stay in Orléans and how the students’ language use in oral interaction develops during this period. The latter will be examined through the example of discourse marker use.

Insects are successful largely because they are highly efficient at optimizing nutrients for reproduction. To understand this efficiency, we have used the stable isotope tracer-tracee-based technique mass isotopomer distribution analysis (MIDA) to follow metabolic allocation in insects in vivo. Based largely on application of these techniques, we had three aims during the fellowship:  
a)    To adapt MIDA to study allocation of carbohydrates acquired during host feeding by the parasitoid Eupelmus vuiletti to fat production.
b)    To study sex pheromone storage in a moth (Bombyx mori).
c)    To write a significant, high impact review on insect physiology.
We successfully adapted MIDA to study fat acquisition in E. vuiletti. Essentially, females allowed to feed on a glucose drop, turned over their hemolymph trehalose substantially (ca. 30-40%). However, very little of this acquired sugar was converted to fat. Moreover, isotopic enrichment of fat was substantially less than that of the trehalose, indicating that other (non-labeled) sources of precursor are used for this fat synthesis. This supports the finding that parasitoids can synthesize fat, but only in very small amounts in comparison to their carbohydrate acquisition. These techniques were transferred to staff and students at IRBI.
Problems with supply of insects meant that we could not fully study sex pheromone storag in B. mori. However, we were able to demonstrate that females, when synthesizing pheromone, stored most pheromone on the gland cuticular surface, rather than intracellularly, thereby facilitating emission of pheromone.  
Finally, we wrote and submitted a proposal for a review on insect exocrine glands for the highly prestigious Annual Review of Entomology (2022 IF = 23.8). We were notified of the success of our proposal in December 2022. Thereafter , a considerable portion of the visit was dedicated to researching, synthesizing, and writing this review. The manuscript will be submitted in January 2024 and, hopefully, published in January 2025.
 

The accelerated digital development characterizing today's society multiplies and blurs educational contexts. In this regard, it becomes necessary to create learning spaces supported by ICT (Information and Communication Technology) that integrate formal and informal contexts, where each person decides what, how, and when to learn. From this perspective, the proposal is to create learning ecologies with learning resources based on a content curation process that retrieves, develops, and shares educational digital content according to the interests and informational needs of the professors. This study aims to analyze the learning resources that make up the learning ecologies available to professors at the University of Orléans. The presentation includes the theoretical foundations underpinning the research and its main results from the qualitative perspective of educational research.

This paper presents a security architecture for the Internet of Medical Things (IoMT), striving to protect sensitive data stored, processed, and transferred in such a system. It is based on a 5-layer architecture for IoMT systems and defines security mechanisms and techniques that can be employed on the different layers in order to protect medical data in its whole lifecycle adequately. Additionally, we also discuss the most common security requirements and attacks from literature which served as the basis for the security architecture. The former can be implemented on various heterogenous IoMT devices and environments.

The Earth’s radiation environment couples to the upper atmosphere through precipitation of energetic electrons in high-latitude regions. This precipitation is driven by electromagnetic waves in the plasma environment around the Earth, including waves generated by lightning discharges. We use data from the DEMETER mission, built and operated by LPC2E between 2004-2010, to better understand the propagation characteristics of these lightning-generated signals and their effects on the radiation environment. Further, we use lessons and heritage from the DEMETER mission to inform design decisions and data analysis techniques for the upcoming CANVAS mission, a collaboration between the University of Colorado Boulder and LPC2E. CANVAS is expected to launch in mid-2024.
