Abstract

Dans les débats d’aujourd’hui sur la recherche d’une croissance durable de l’économie, le développement et la diffusion des hautes technologies sont reconnus comme des éléments décisifs. Il s’agit de trouver les moyens et l’organisation pertinents pour mettre en œuvre les découvertes et les applications scientifiques les plus récentes et assurer le renouveau du tissu économique et social. La conception de produits et de services dans ces domaines, la création et l’essor d’entreprises petites et grandes, le soutien ou les commandes que peuvent leur apporter les différents pouvoirs publics, le rôle des universités et de la recherche, leur impact sur l’environnement, les changements de la société civile et de l’opinion à leur égard sont devenus des enjeux majeurs. Outre la croissance, il y va de la souveraineté, de l’indépendance nationale et de la capacité d’alliance et de coopération des nations. Ce livre est le premier ouvrage d’ensemble qui, loin de se limiter à un secteur, aborde leur histoire parallèle aux États-Unis et en France depuis 1945, deux pays aussi différents par leurs atouts et leur culture que liés par leur histoire et la géopolitique. Il aborde la question de l’hégémonie américaine vis-à-vis des Européens et celle des voies qui s’offrent à eux dans ce contexte, seuls ou ensemble. Il ne se contente pas, en effet, d’une approche nationale : il traite du niveau local et régional comme de la place de l’Europe et du rôle des organismes internationaux. Une première partie analyse les réussites mais aussi quelques échecs du pilotage par l’État de secteurs pionniers. Une deuxième partie concerne spécifiquement les ressources stratégiques et les enjeux militaires. Une troisième partie aborde l’écologie des entreprises de haute technologie et de leurs produits : accès aux technologies, financements, demande, marchés. Une quatrième partie étudie comment, pour faire face au double défi de la concurrence et de la coopération, ont été trouvées des articulations entre les logiques territoriales régionale, nationale et européenne qui sont devenues des bases d’une innovation soutenue dans les hautes technologies. Une table ronde entre acteurs du temps présent fait des comparaisons à l’échelle du monde, débat des forces et des faiblesses françaises en la matière, et s’interroge sur les politiques publiques possibles aux échelles nationale et européenne. Ce livre associe historiens, sociologues, géographes et politistes étrangers et français à des témoignages d’acteurs français importants des secteurs privé et public.

Abstract

Since its inception, the Deep Carbon Observatory (DCO) has coalesced a multidisciplinary and international group of researchers focused on understanding and quantifying Earth’s deep carbon budget. Carbon is the fourth most abundant element in the universe, and understanding carbon chemistry under a variety of environmental conditions impacts all aspects of planetary sciences, including planet formation, the form and function of planetary interiors, and the origin and diversity of life. DCO recognizes that is integrating and promoting the contributions of early career scientists are integral to the advancement of knowledge regarding the quantities, movements, origins, and forms of Earth’s deep carbon through field, experimental, analytical, and computational research. Early career scientists represent the future of deep carbon science and contribute substantially to ongoing research by implementing innovative ideas, challenging traditional working schemes, and bringing a globally interconnected perspective to the scientific community. This research topic highlights the contributions at the forefront of deep carbon research by DCO Early Career Scientist community. The manuscripts of this Frontiers e-volume bear evidence of the rapid advances in deep carbon science, and highlights the importance of approaching this field from a plethora of different angles integrating disciplines as diverse as mineralogy, geochemistry and microbiology. This integration is fundamental in understanding the movements and transformations of carbon across its deep cycle.

Abstract

This work concerns the characterization of high-temperature superconducting REBCO Roebel cables for use in accelerator magnets. The effects of bending, torsion and compressive stress on the cable are investigated. The second part concerns the effect of inter-strand resistance on the cable properties. A two-parameter model is proposed to describe inter-strand connections and predict the effect on AC loss and stability. Additionally, the AC loss and stability are experimentally investigated.

Abstract

This book provides a broad introduction to the physics and technology of the High Luminosity Large Hadron Collider (HL-LHC). This new configuration of the LHC is one of the major accelerator projects for the next 20 years and will give new life to the LHC after its first 15-year operation. Not only will it allow more precise measurements of the Higgs boson and of any new particles that might be discovered in the next LHC run, but also extend the mass limit reach for detecting new particles. The HL-LHC is based on the innovative accelerator magnet technologies capable of generating 11–13 Tesla fields, with effectiveness enhanced by use of the new Achromatic Telescopic Squeezing scheme, and other state-of-the-art accelerator technologies, such as superconducting compact RF crab cavities, advanced collimation concepts, and novel power technology based on high temperature superconducting links.The book consists of a series of chapters touching on all issues of technology and design, and each chapter can be read independently. The first few chapters give a summary of the whole project, of the physics motivation and of the accelerator challenges. The subsequent chapters cover the novel technologies, the new configurations of LHC and of its injectors as well as the expected operational implications. Altogether, the book brings the reader to the heart of technologies for the leading edge accelerator and gives insights into next generation hadron colliders.Contents:Foreword (S Myers)Preface (O Brüning and L Rossi)Introduction to the HL-LHC Project (L Rossi and O Brüning)The Physics Landscape of the High Luminosity LHC (M Mangano)The HL-LHC Machine (I Bejar, O Brüning, P Fessia, L Rossi, R Tomas and M Zerlauth)The HL-LHC Accelerator Physics Challenges (S Fartoukh and F Zimmermann)Interface with Experimental Detector in the High Luminosity Run (H Burkhardt)Superconducting Magnet Technology for the Upgrade (E Todesco, G Ambrosio, P Ferracin, J M Rifflet, G L Sabbi, M Segreti, T Nakamoto, R van Weelderen and Q Xu)Crab Cavity Development (R Calaga, E Jensen, G Burt and A Ratti)Powering the Hi-Luminosity Triplets (A Ballarino and J P Burnet)Cryogenics for HL-LHC (L Tavian, K Brodzinski, S Claudet, G Ferlin, U Wagner and R van Weelderen)The "Environmental" Challenges: Impact of Radiation on Machine Components (M Brugger, F Cerutti and L S Esposito)Radiation Protection Considerations (C Adorisio, S Roesler, C Urscheler and H Vincke)Machine Protection with a 700 MJ Beam (T Baer, R Schmidt, J Wenninger, D Wollmann and M Zerlauth)Cleaning Insertions and Collimation Challenges (S Redaelli, R B Appleby, A Bertarelli, R Bruce, J M Jowett, A Lechner and R Losito)Long-Range Beam–Beam Compensation Using Wires (F Zimmermann and H Schmickler)Impedance and Component Heating (E Métral, F Caspers, N Mounet, T Pieloni and B Salvant)Challenges and Plans for the Proton Injectors (R Garoby)New Injectors: The Linac4 Project and the New H– Source (J Lettry and M Vretenar)Challenges and Plans for the Ion Injectors (D Manglunki)Challenges and Plans for Injection and Beam Dump (M Barnes, B Goddard, V Mertens and J Uythoven)Beam Instrumentation and Diagnostics for the LHC Upgrade (E Bravin, B Dehning, R Jones and T Lefevre)Heavy-Ion Operation of HL-LHC (J M Jowett, M Schaumann and R Versteegen)Implications for Operations (G Arduini, M Lamont, T Pieloni and G Rumolo)Readership: Researchers and graduates in accelerator physics and engineering.

Abstract

The 16S ribosomal RNA gene commonly serves as a molecular marker for investigating microbial community composition and structure. Vast amounts of 16S rRNA amplicon data generated from environmental samples thanks to the recent advances in sequencing technologies allowed microbial ecologists to explore microbial community dynamics over temporal and spatial scales deeper than ever before. However, widely used methods for the analysis of bacterial communities generally ignore subtle nucleotide variations among high-throughput sequencing reads and often fail to resolve ecologically meaningful differences between closely related organisms in complex microbial datasets. Lack of proper partitioning of the sequencing data into relevant units often masks important ecological patterns. Our research topic contains articles that use oligotyping to demonstrate the importantance of high-resolution analyses of marker gene data, and providides further evidence why microbial ecologists should open the "black box" of OTUs identified through arbitrary sequence similarity thresholds.

Abstract

The huge volume of multi-modal neuroimaging data across different neuroscience communities has posed a daunting challenge to traditional methods of data sharing, data archiving, data processing and data analysis. Neuroinformatics plays a crucial role in creating advanced methodologies and tools for the handling of varied and heterogeneous datasets in order to better understand the structure and function of the brain. These tools and methodologies not only enhance data collection, analysis, integration, interpretation, modeling, and dissemination of data, but also promote data sharing and collaboration. This Neuroinformatics Research Topic aims to summarize the state-of-art of the current achievements and explores the directions for the future generation of neuroinformatics infrastructure. The publications present solutions for data archiving, data processing and workflow, data mining, and system integration methodologies. Some of the systems presented are large in scale, geographically distributed, and already have a well-established user community. Some discuss opportunities and methodologies that facilitate large-scale parallel data processing tasks under a heterogeneous computational environment. We wish to stimulate on-going discussions at the level of the neuroinformatics infrastructure including the common challenges, new technologies of maximum benefit, key features of next generation infrastructure, etc. We have asked leading research groups from different research areas of neuroscience/neuroimaging to provide their thoughts on the development of a state of the art and highly-efficient neuroinformatics infrastructure. Such discussions will inspire and help guide the development of a state of the art, highly-efficient neuroinformatics infrastructure.

Abstract

Aftereffects generally occur after a prolonged exposure (adaptation) to a first stimulus possessing one given property followed by presentation of a stimulus bearing a neutral value of that property. The aftereffect consists in a change in appearance of the neutral stimulus following the adapter, compared to the appearance of the neutral stimulus when it is perceived without any previous exposure to the adapter. The transient phenomena of perceptual aftereffects are believed to depend on the activation of neuron populations that respond selectively to a given property of the stimuli. Studying how adaptation occurs (which stimulus properties are sensitive to it, which timings are necessary, whether individual differences modulate its occurrence) has thus become an indirect way to probe the plasticity of sensory functions in the nervous system, recently extending to more cognitive and representational aspects of neural coding. In the last two decades, indeed, it has been demonstrated that aftereffects occur not only for low-level properties of stimuli (such as motion, color, or orientation) but also for high-level properties. Many studies have proven that high-level proprieties of the stimuli, e.g. gender, identity, ethnicity, or age of a face or a voice, are sensitive to this phenomenon. It has been shown, for example, that the prolonged exposure to a female or male face produces a gender misperception in the opposite direction when an androgynous face is shown after the adapter. Furthermore, recent studies have also shown that aftereffects are not strictly contingent upon the physical features that make up stimuli, but they seem to run across the high-level proprieties subjects are adapted to. These evidences are supported by cross-category adaptation studies, which underlie how aftereffects occur even across stimuli that do not share physical features (e.g. bodies and faces) but that instead, share common higher-level properties, such as gender. Given the growing body of research focused on adaptation and aftereffects in high-level perception at the boundaries with perceptual learning, attention and cognition, the purpose of this topic is to provide a picture of the state of the art relative to the specific phenomena of adaptation in high-level perceptual processing.

Abstract

The purpose of this Special Issue, “Egg Consumption and Human Health,” is two-fold: 1) to address the lack of effect of eggs in increasing heart disease risk (this discussion will be based on what is known from epidemiological analysis and clinical interventions) and 2) to focus on the role of eggs in protecting against chronic disease. Eggs are more than just a cholesterol-containing food. They possess numerous nutritional benefits. This Special Issue will discuss eggs as a source of high-quality protein for individuals across the life spectrum, as a substantial source of choline (a known neurotransmitter involved in cognitive function), and as a source of highly bioavailable lutein and zeaxanthin (two carotenoids well-recognized for their major role in protecting against age-related macular degeneration and cataracts, as well as for their antioxidant and anti-inflammatory properties). Finally, the potential of incorporating eggs for weight loss interventions, due to their low glycemic index and their satiety effects, will also be discussed.
