Abstract

The field of high-power laser-plasma interaction has grown in the last few decades, with applications ranging from laser-driven fusion and laser acceleration of charged particles to laser ablation of materials. This comprehensive text covers fundamental concepts including electromagnetics and electrostatic waves, parameter instabilities, laser driven fusion,charged particle acceleration and gamma rays. Two important techniques of laser proton interactions including target normal sheath acceleration (TNSA) and radiation pressure acceleration (RPA) are discussed in detail, along with their applications in the field of medicine. An analytical framework is developed for laser beat-wave and wakefield excitation of plasma waves and subsequent acceleration of electrons. The book covers parametric oscillator model and studies the coupling of laser light with collective modes.

Abstract

L’importance des interactions parent-enfant est un sujet qui suscite un intérêt croissant dans la littérature. Beaucoup d’auteurs s’y intéressent car nous savons désormais qu’elles sont susceptibles d’avoir un impact sur le développement du langage. Néanmoins, la littérature n’offre actuellement que très peu de données concernant les facteurs susceptibles d’influencer la qualité des interactions parent-enfant de manière positive ou négative. De plus, il n’existe pas encore d’outils d’évaluation valides de ces interactions qui permettent d’évaluer ces différents facteurs afin d’obtenir des conclusions solides. &#13;Dès lors, l’objectif de ce mémoire est de mieux comprendre ce qui peut influencer les mesures d’évaluation de la qualité des interactions parent-enfant. Nous nous sommes penchés sur trois questions : La première concerne l’influence de l’âge des enfants en lien avec les études de Barnett, Gustafsson, Deng, Mills-Koonce, & Cox (2012) et D’Odorico & Jacob (2006) qui s’intéressent au principe de bidirectionnalité de l’interaction et à l’influence des compétences langagières de l’enfant sur le comportement du parent. La seconde question s’intéresse à l’influence de la situation d’évaluation en lien avec les études de Sosa (2016) et Stich, Girolametto, Johnson, Cleave, & Chen (2015) qui étudient la complexité du langage parental en fonction du contexte d’interaction. Notre dernière question porte sur l’influence du type de cotation (échelle de Likert vs. mesures métriques) en lien avec l’étude de Down, Levickis, Hudson, Nicholls, & Wake (2014) qui observent une corrélation satisfaisante entre une note globale de réactivité verbale du parent et une mesure précise de la fréquence des réponses promptes et contingentes du parent. &#13;Pour cela, nous avons analysé soixante vidéos d’interaction entre un parent et son enfant (âgé de 12 à 36 mois). Ces dyades ont été filmées à deux reprises (T1 et T2) dans trois situations de jeu (jeu libre, jeu de performance et lecture de livre) à un an d’intervalle. &#13;Les résultats de cette étude suggèrent que l’âge de l’enfant, la situation d’évaluation ainsi que le type de cotation influencent la qualité des interactions parent-enfant. Premièrement, certains aspects des interactions varient en fonction de l’âge. En effet, les enfants ont tendance à produire plus d’intentions communicatives au T2. Le parent va par conséquent se montrer plus sensible et offrir davantage de stratégies de soutien au développement langagier au T2 qu’au T1. Ensuite, concernant le contexte, il s’avère que le jeu libre est le contexte le plus riche et également le plus représentatif des interactions parent-enfant quotidiennes. Ce contexte permet davantage à l’enfant d’être impliqué dans les interactions. Son implication va le pousser à interagir davantage avec son parent qui va pouvoir lui offrir un plus grand nombre de stratégies de soutien au développement langagier que dans un autre contexte. Enfin, nous ne pouvons pas actuellement confirmer que les mesures globales et métriques permettent d’obtenir des résultats semblables. Des études supplémentaires qui utilisent une mesure globale qui s’intéresse à plus d’aspects des interactions (sensibilité parentale, directivité…) sont nécessaires.

Abstract

This volume discusses different enzyme-catalyzed ligation methodologies for a variety of different chemical transformations. This book wants readers to view enzymes as a powerful tool in both academic and industrial research. Chapters in this book cover topics such as sortase A-mediated generation of site-specifically conjugated antibody-drug conjugates; omniligase-catalyzed inter- and intramolecular ligation; ligation catalyzed by microbial transglutaminase; peptide cyclization mediated by cyanobactin macrocyclases, butelase 1 and sortase A; using BioID as a tool for protein proximity labeling in living cells; and inducible, selective labeling of proteins via enzymatic oxidation of tyrosine. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Enzyme-Mediated Ligation Methods is a valuable resource for students and scientists from different disciplines who are interested in using enzymatic strategies to answer their research questions. .

Abstract

This volume is the first-ever complete treatise on polymyxins and presents the most comprehensive and up-to-date reviews of all major research and clinical topics from chemistry, microbiology, pharmacology, clinical use, to drug discovery. All chapters were written by internationally leading researchers and clinicians in the field. It is our wish that readers discover the importance of polymyxin structure in relation to the mechanisms of activity, resistance and toxicity. We emphasized that reliable analytic methods for polymyxins are critical when investigating their pharmacokinetics (PK) and pharmacodynamics (PD). The complicated dose definitions and different pharmacopoeial standards have already compromised the safe use of polymyxins in patients. Therefore, informed by the latest pharmacological information, scientifically-based dosing recommendations have been proposed for intravenous polymyxins. Considering the PK/PD limitations and potential development of resistance, polymyxin combinations are encouraged; however, the current literature has not shown definite microbiological benefits, possibly because most clinical studies to date overlooked key PK/PD principles. Nephrotoxicity is the major dose-limiting factor and it is imperative to elucidate the mechanisms and develop novel approaches to minimize polymyxin-associated toxicities. In addition, the anti-endotoxin effect of polymyxins supports their clinical use to treat Gram-negative sepsis. Fortunately, the discovery of new-generation polymyxins with wider therapeutic windows has benefited from the latest achievements in polymyxin research. This book provides extensive pharmacological information on polymyxins to infectious diseases clinicians, pharmacists, clinical microbiologists, antimicrobial pharmacologists, and pharmaceutical scientists, and is an essential read for those who aim to develop novel polymyxins and improve their clinical use as a last-line defense against Gram-negative ‘superbugs’.

Abstract

Saviez-vous que les arbres contribuent à la formation des nuages ? Que les loups peuvent modifier le cours des rivières ? Que le sort du sanglier dépend du ver de terre ? Dans la nature, tout est lié - comme les rouages d'une grande horloge. Aussi la moindre modification a-t-elle des répercussions insoupçonnées. Observateur scrupuleux et conteur passionné, Peter Wohlleben nous dévoile ces liens subtils qui unissent animaux et plantes, forêts et rivières, montagnes et climat...Il nous met aussi en garde contre une intervention humaine imprudente dans cette mécanique dont nous ne maîtrisons pas tous les ressorts : les meilleures intentions du monde peuvent produire des catastrophes. Dans ce dernier tome de sa trilogie au succès planétaire, vendue à plus d'un million d'exemplaires en France, le plus célèbre des forestiers signe un plaidoyer pour l'équilibre délicat du vivant, ce bien commun de l'humanité.Peter Wohlleben est forestier depuis une vingtaine d'années. Après le succès mondial de La Vie secrète des arbres (traduit en plus de trente langues) et de La Vie secrète des animaux, ce troisième volet est devenu un best-seller dès sa sortie en Allemagne.
