Laboratoire Interdisciplinaire des Energies de Demain
Présentation
Le laboratoire en quelques mots
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.

Thèmes de recherche
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.

[hal-02088493] Socioeconomic differences in childhood vaccination in developed countries: a systematic review of quantitative studies
Date: 2 avr 2019 - 23:40
Desc: Introduction: The reasons for vaccine hesitancy and its relation to individual socioeconomic status (SES) must be better understood. Areas covered: This review focused on developed countries with programs addressing major financial barriers to vaccination access. We systematically reviewed differences by SES in uptake of publicly funded childhood vaccines and in cognitive determinants (beliefs, attitudes) of parental decisions about vaccinating their children. Using the PRISMA statement to guide this review, we searched three electronic databases from January 2000 through April 2016. We retained 43 articles; 34 analyzed SES differences in childhood vaccine uptake, 7 examined differences in its cognitive determinants, and 2 both outcomes. Expert commentary: Results suggest that barriers to vaccination access persist among low-SES children in several settings. Vaccination programs could be improved to provide all mandatory and recommended vaccines 100% free of charge, in both public organizations and private practices, and to reimburse vaccine administration. Multicomponent interventions adapted to the context could also be effective in reducing these inequalities. For specific vaccines (notably for measles, mumps, and rubella), in UK and Germany, uptake was lowest among the most affluent. Interventions carefully tailored to respond to specific concerns of vaccine-hesitant parents, without reinforcing hesitancy, are needed.
[hal-03152339] Identification and characterization of PDC1, a novel protein involved in the epigenetic cell degeneration Crippled Growth in Podospora anserina
Date: 25 fév 2021 - 15:05
Desc: The model fungus Podospora anserina exhibits Crippled Growth (CG), a cell degeneration process linked to the spreading of a prion-like hereditary element. Previous work has shown that the PaMpk1 MAP kinase and the PaNox1 NADPH oxidase are key player in setting up CG. Here, we identified PDC1, a new gene that negatively regulates the PaMpk1 pathway, by identifying the gene mutated in the PDC2205 mutant. This mutant exhibits strong CG in conditions where the wild-type does not. PDC1 encodes a small protein conserved in other Pezizomycotina. The protein contains four evolutionary-conserved cysteines, a tryptophan and a histidine; all six amino-acid are essential for function. PDC1 is located in the cytosol and is present in lower amounts in stationary hyphae in accordance with its role as a repressor. Epistasis analyses place PDC1 between PaMpk1 and PaNox1.
[hal-03156600] Adapted or Adaptable: How to Manage Entropy Production?
Date: 2 Mar 2021 - 15:31
Desc: Adaptable or adapted? Whether it is a question of physical, biological, or even economic systems, this problem arises when all these systems are the location of matter and energy conversion. To this interdisciplinary question, we propose a theoretical framework based on the two principles of thermodynamics. Considering a finite time linear thermodynamic approach, we show that non-equilibrium systems operating in a quasi-static regime are quite eterministic as long as boundary conditions are correctly defined. The Novikov–Curzon–Ahlborn derivation applied to non-endoreversible systems then makes it possible to precisely determine the conditions for obtaining characteristic operating points. As a result, power maximization principle (MPP), entropy minimization principle (mEP), efficiency maximization, or waste minimization states are only specific modalities of system operation. We show that boundary conditions play a major role in defining operating points because they define the intensity of the feedback that ultimately characterizes the operation. Armed with these thermodynamic foundations, we show that the intrinsically most efficient systems are also the most constrained in terms of controlling the entropy and dissipation production. In particular, we show that the best figure of merit necessarily leads to a vanishing production of power. On the other hand, a class of systems emerges, which, although they do not offer extreme efficiency or power, have a wide range of use and therefore marked robustness. It therefore appears that the number of degrees of freedom of the system leads to an optimization of the allocation of entropy production
