Le Laboratoire Interdisciplinaire des Energies de Demain (LIED) a pour objectif fondateur de développer « l’écologie des énergies », en menant à la fois recherches scientifiques et techniques guidées par les problèmes à résoudre dans le cadre de la transition énergétique et de l’accroissement des besoins mondiaux en énergie.
Il répond à la nécessité d’une approche interdisciplinaire des problèmes posés, en fédérant les membres – universitaires ou venant d’entreprises – des secteurs Sciences (Biologie, Chimie, Informatique, Mathématiques, Physique, Sciences de l’Ingénieur, Sciences de la Terre) et Sciences Humaines et Sociales (Anthropologie, Economie, Géographie, Histoire, Philosophie, Ecologie, Sciences politiques, Sociologie).
Les membres de l’UMR LIED (17 du secteur sciences et 9 du secteur SHS) se composent de 8 PR, 11 MCU, 3 personnels CNRS (1CR, 1IR, 1assimilée) et de 4 consultants. Le LIED constitue également la pierre angulaire de l’Institut des Energies de Demain (IED), appelé à devenir l’un des quatre instituts transversaux de l’IDEX SCP. Celui-ci comprend l’UMR LIED, la fédération IED et le réseau international PIERI (Paris Interdisciplinary Energy Research Institute).
L’ensemble forme un « dispositif » en cinq modes d’appartenance dont le premier est l'UMR LIED proprement dite. Le deuxième mode d’appartenance à LIED rassemble des membres de la plupart des laboratoires du campus Paris Diderot, irriguant le LIED par ses racines pluridisciplinaires. Deux autres modes l’ouvrent à des laboratoires d'autres PRES et aux entreprises, dont bon nombre le soutiennent très concrètement, en particulier celles qui font partie du conseil scientifique du LIED : AREVA, Bouygues, EDF, Saint-Gobain. Son ouverture internationale est le réseau PIERI.
La figure, généralisable à plusieurs fédérations de recherche, correspond au cas de deux : celle de l'institut des énergies de demain (avec l’UMR LIED représentée par un cercle blanc noté 1) et d’une autre centrée sur le laboratoire X (représenté par un cercle blanc noté X). Les laboratoires du campus Paris Diderot mutualisés avec le LIED sont les cercles colorés notés 2. Ceux satellisés par le X sont des cercles notés ? à colorer selon leurs disciplines. Les laboratoires interagissant avec le LIED et X sont les cercles colorés notés 3 ou 4 selon leurs degrés d’interaction avec ces laboratoires (sphères 3 ou 4 respectivement). Le caractère international du PIERI est symbolisé par un rectangle d’où proviennent des interactions multiformes.

The LIED and its international network PIERI (Paris Interdisciplinary Energy Research Institute) have been launched in the context of increased worldwide demands in energy in the face of environmental concerns, i.e. sustainable resources and impact on the climate.
The LIED favours a global approach and aims at resolving questions at the national and international level by a unique multi-disciplinary approach encompassing basic science (Biology, Chemistry, Physics, Informatics, Mathematics, Earth sciences and Engineering) as well as social sciences (Anthropology, Economics, Geography, History, Philosophy, Political sciences), whether in the academic or industrial domain.
· Objectives : Develop basic and applied science in response to the challenges of the “energy transition” with a focus on the interaction between energy, environment and climate. In the domain of biology, the LIED aims at understanding the basic mechanisms underlying energetic processes in microorganisms and in plants. It fosters applied science for the development of production and transformation of biomass.
· Methods : Biochemistry, Genetics, Genomics, Molecular and cellular biology, Bioinformatics.
. Research orientations : balancing fundamental and applied research.
The work of the PIERI is organised around four axes :
♦ Fundamental science and low-carbon energy sources ;
♦ The science and technology of energy efficiency ;
♦ Forecasting, social and economic analysis, and public policy studies ;
♦ Interdisciplinary epistemology.
The titles of first two axes already illustrate the aspiration to combine fundamental and applied research. Two complementary research groups have been established, entitled : ‘Innovative energy sources and biomaterials’ and ‘Energy transport, instabilities and fluctuations’, composed mainly of researchers from sciences and technologies, but with input from social scientists. The third axis is subdivided into six themes, which all bring together the physical and the social sciences, namely :
The geography of energy sourcing ;
The multilevel governance of energy ;
Social representation and innovation : hydrogen and other energy pathways ;
Energy efficiency and modes of consumption ;
Forecasting models and interdisciplinary convergence ;
Smart grids.

Desc: INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is the most common motor neurone disease. It occurs in two forms: (1) familial cases, for which several genes have been identified and (2) sporadic cases, for which various hypotheses have been formulated. Notably, the β-N-methylamino-L-alanine (L-BMAA) toxin has been postulated to be involved in the occurrence of sporadic ALS. The objective of the French BMAALS programme is to study the putative link between L-BMAA and ALS. METHODS AND ANALYSIS: The programme covers the period from 1 January 2003 to 31 December 2011. Using multiple sources of ascertainment, all the incident ALS cases diagnosed during this period in the area under study (10 counties spread over three French regions) were collected. First, the standardised incidence ratio will be calculated for each municipality under concern. Then, by applying spatial clustering techniques, overincidence and underincidence zones of ALS will be sought. A case-control study, in the subpopulation living in the identified areas, will gather information about patients' occupations, leisure activities and lifestyle habits in order to assess potential risk factors to which they are or have been exposed. Specimens of drinking water, food and biological material (brain tissue) will be examined to assess the presence of L-BMAA in the environment and tissues of ALS cases and controls. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the French ethical committee of the CPP SOOM IV (Comité de Protection des Personnes Sud-Ouest & Outre-Mer IV). The results will be published in peer-reviewed journals and presented at national and international conferences.

Desc: Cet ouvrage représente une étape importante de montée en puissance d’un champ interdisciplinaire émergent : l’écologie territoriale. Si des travaux déjà anciens ont traité de questions scientifiques très proches de ce dont il est question en écologie territoriale, il n’y avait pas encore eu d’effort collectif visant à faire émerger une communauté scientifique destinée à se structurer et à essaimer.

Desc: Under suitable conditions, an immersed granular bed can be destabilized by local thermal forcing and the induced buoyant force. The destabilization is evident from the triggering and establishment of a dense fluid-like granular plume. Varying the initial granular layer average height h, time series of the free layer surface are extracted, allowing us to dynamically compute the underlying volume of the granular layer. The initial interface deformation, the lowering of the average granular interface (i.e. decrease of the granular layer volume) and the emission of a plume are observed and analyzed. We show that the phenomenon is mainly driven by heat transfer, for large h and also involves variable height thermal boundary condition & Darcy's flow triggering, for small h. Simple modeling with no adjustable parameter not only allows us to capture the observed scaling power laws but is also in quantitative agreement with the obtained experimental data.

Desc: BACKGROUND: Confronted with a rise in vaccine hesitancy, public health officials increasingly try to involve the public in the policy decision-making process to foster consensus and public acceptability. In public debates and citizen consultations tensions can arise between the principles of science and of democracy. To illustrate this, we analyzed the 2016 citizen consultation on vaccination organized in France. This consultation led to the decision to extend mandatory vaccination. METHODS: The analysis combines qualitative and quantitative methods. We analyze the organization of the consultation and its reception using the documents provided by its organizing committee, articles of newsmedia and the contents of 299 vaccine-critical websites. Using methods from computational linguistics, we investigate the 10435 public comments posted to the consultation's official website. RESULTS: The combination of a narrow framing of debates (how to restore trust in vaccination and raise vaccination coverages) and a specific organization (latitude was given to the orientation committee with a strong presence of medical experts) was successful in avoiding legitimizing vaccine critical arguments. But these choices have been at the expense of a real reflection on the acceptability of mandatory vaccination and it did not quell vaccine-critical mobilizations. CONCLUSIONS: Public health officials must be aware that when trying to increase democratic participation into their decision-making process, how they balance inputs from the various actors and how they frame the discussion determine whether this initiative will provide meaningful information and democratic legitimacy.
