Abstract:
The very nature of the last bacterial common ancestor (LBCA), in particular the characteristics of its cell wall, is a critical issue to understand the evolution of life on earth. Although knowledge of the relationships between bacterial phyla has made progress with the advent of phylogenomics, many questions remain, including on the appearance or disappearance of the outer membrane of diderm bacteria (also called Gram-negative bacteria). The phylogenetic transition between monoderm (Gram-positive bacteria) and diderm bacteria, and the associated peptidoglycan expansion or reduction, requires clarification. Herein, using a phylogenomic tree of cultivated and characterized bacteria as an evolutionary framework and a literature review of their cell-wall characteristics, we used Bayesian ancestral state reconstruction to infer the cell-wall architecture of the LBCA. With the same phylogenomic tree, we further revisited the evolution of the division and cell-wall synthesis (dcw) gene cluster using homology- and model-based methods. Finally, extensive similarity searches were carried out to determine the phylogenetic distribution of the genes involved with the biosynthesis of the outer membrane in diderm bacteria. Quite unexpectedly, our analyses suggest that all cultivated and characterized bacteria might have evolved from a common ancestor with a monoderm cell-wall architecture. If true, this would indicate that the appearance of the outer membrane was not a unique event and that selective forces have led to the repeated adoption of such an architecture. Due to the lack of phenotypic information, our methodology cannot be applied to all extant bacteria. Consequently, our conclusion might change once enough information is made available to allow the use of an even more diverse organism selection.

Abstract:
The article considers L.N. Tolstoy not only as a thinker who represents but also accomplishes Enlightenment. Through a comparison of his ideas with philosophy of Spinoza and Diderot, the author clarifies the aspects of the transition from Enlightenment to the unique Tolstoy’s religious and philosophical doctrine. A special attention is paid to the way of thinking, the relation to science and the specifics of the worldview of Tolstoy and Diderot. The contradiction between the way of thinking and the way of life of the three philosophers is revealed. The author also researches their philosophical interpretations of the nature of creative thought. Diderot describes the nature through the concept of paradoxism, Spinoza describes it with the concept of integrity, and Tolstoy uses the method of cohesion that he founds in literary works. If for the philosophers of European Enlightenment, the way of thinking is directly related to human nature, which is presented as a unity of natura naturans and natura naturata, then Tolstoy considers that the most important is a certain a priori sense of life, which is imbued with faith in God and with an instinct of self-giving that is love for the Supreme and other people. The method of cohesion leads Tolstoy away from the direct continuation of educational ideas, stressing the significance of appealing not only to reason but also to creative intuition. Tolstoy gradually moves away from rational perception of Life to its religious and existential foundations. Tolstoy’s worldview undergoes transition from the idea of a natural man to the idea of a human being who lives by commandments of Christ. Starting from the worldview of Enlightenment, Tolstoy comes to the creation of religious and philosophical doctrine, which is relevant to early 20th century.

Researchers from multiple disciplines have tried to understand the mechanism of stock market crashes. Precursory patterns before crashes agree with various empirical studies published by econophysicists, namely the prolific work of Didier Sornette. We intend to add more empirical evidence of synchronization of trading and demonstrate the prospect of predicting stock market crashes by analyzing clusters’ dynamics in the period of bubble build-up leading to a crash. We apply the Potential-based Hierarchical Agglomerative (PHA) Method, the Backbone Extraction Method, and the Dot Matrix Plot on S&P500 companies daily returns. Our innovative approach is proposed in this paper, empirical results and discussion presented in another publication.

Abstract:
Paper aims to explore the progress in eco-efficiency and the course of decoupling of environmental impact from economy growth in Lithuania during 1990–2008. For better interpretation of ongoing changes in eco-efficiency the concept of double decoupling was applied. Decoupling of resource consumption from economy growth is considered as primary decoupling, and decoupling of environmental pollution from resource consumption is considered as secondary decoupling. Energy intensity is treated as indicator of primary decoupling and pollution intensity as indicator of secondary decoupling. Over investigated period an essential primary decoupling took place and final energy intensity was reduced approximately 2.5 times in Lithuania and has converged to the level of EU-15 on average. Transition to the market economy, shift to the modern technologies, increased energy prices and structural changes of Lithuanian economy are considered as the main drivers for this achievement. Progress in secondary decoupling was not so pronounced and pollution intensity is still 2 times higher than in EU-15. Though energy and transport sectors are identified as the main “hot spots” to tackle relatively high pollution intensity, focus on tools and measures benefiting reduction of both energy and pollution intensity are discussed. Santrauka Straipsnyje analizuojama Lietuvos pažanga ekologinio veiksmingumo srityje ir poveikio aplinkai atsiejimas nuo ekonomikos 1990–2008 m. Įvykusiems ekologinio veiksmingumo pokyčiams įvertinti pritaikyta dvigubo atsiejimo koncepcija. Energijos intensyvumas traktuojamas kaip pirminio atsiejimo, t. y. ekonomikos augimo atsiejimo nuo energijos išteklių naudojimo, rodiklis, teršimo intensyvumas – kaip antrinio atsiejimo, t. y. aplinkos teršimo atsiejimo nuo energijos vartojimo, rodiklis. Per analizuojamą laikotarpį pavyko atsieti ekonomikos augimą nuo energijos vartojimo, galutinės energijos intensyvumą Lietuvoje sumažinti maždaug 2,5 karto ir beveik pasiekti ES-15 vidurkį. Perėjimas prie rinkos ekonomikos, modernių technologijų, išaugusios energijos kainos ir struktūriniai Lietuvos ekonomikos pokyčiai laikomi pagrindiniais šią ekonomikos ir aplinkos požiūriu svarbią pažangą lėmusiais veiksniais. Pažanga antrinio atsiejimo srityje buvo ne tokia didelė ir taršos intensyvumas, t. y. į aplinką patenkančių teršalų kiekis suvartotos energijos vienetui, Lietuvoje yra vis dar apie du kartus didesnis nei ES-15. Energetika ir transportas įvardijami kaip pagrindiniai sektoriai, kuriuose reikia skirti daugiau dėmesio atitinkamoms priemonėms, siekiant mažinti didelį taršos intensyvumą.

Résumé BLANCHET Didier. - Croissance de la population et du produit par tête au cours de la transition démographique : un modèle malthusien peut-il rendre compte de leurs relations ? Cet article examine comment doit évoluer au cours du temps la liaison entre croissance démographique et économique dans un modèle de transition démographique où les deux croissances sont tirées simultanément par le progrès technique, c'est-à-dire un modèle dérivé du modèle malthusien standard, par comparaison aux modèles à progrès technique endogène, auxquels est généralement associé le nom d'E. Boserup. On montre qu'un tel modèle peut bien rendre compte de corrélations successivement positives et négatives entre les deux variables. Un examen des données de la Banque Mondiale indique que ce schéma est effectivement celui observé dans la réalité, avec l'apparition récente de corrélations fortement négatives entre les deux variables, alors que celles-ci ont longtemps été non-significatives et parfois positives. En revanche, le modèle à progrès technique endogène impliquerait que c'est plutôt au début du processus d'expansion démographique et économique que devraient apparaître ces corrélations négatives.

Abstract:
In the middle of the seventeenth century, scholarship on ancient Stoicism generally understood it to be a form of theism. By the middle of the eighteenth century, Stoicism was widely (though not universally) reckoned a variety of atheism, both by its critics and by those more favourably disposed to its claims. This article describes this transition, the catalyst for which was the controversy surrounding Spinoza's philosophy, and which was shaped above all by contemporary transformations in the historiography of philosophy. Particular attention is paid to the roles in this story played by Thomas Gataker, Ralph Cudworth, J. F. Buddeus, Jean Barbeyrac, and J. L. Mosheim, whose contributions collectively helped to shape the way in which Stoicism was presented in two of the leading reference works of the Enlightenment, J. J. Brucker's Critical History of Philosophy and the Encyclopédie of Diderot and d'Alembert.

Abstract:
L’enveloppe bactérienne est l’une des structures cellulaires les plus anciennes et les plus fondamentales. Toutefois, de nombreux aspects concernant sa diversité et son histoire évolutive sont encore inconnus. Dans cette thèse, j’ai profité du nombre croissant de génomes disponibles dans les bases de données publiques, afin de mener une analyse de phylogénomique et de génomique comparative à une large échelle évolutive. Les deux objectifs de ce travail doctoral étaient (i) d’identifier de nouvelles lignées didermes au sein des Firmicutes pour éclairer la transition monoderme/diderme, et (ii) d’élucider l’histoire évolutive de l’enveloppe cellulaire chez les bactéries et d’en déduire la nature chez le LBCA.En résumé, les résultats que j'ai obtenus au cours de cette thèse fournissent une avancée significative dans notre compréhension de la diversité et de l'évolution de l'enveloppe cellulaire, et sur l'une des transitions majeures de l'histoire des bactéries, celle entre les monodermes et les didermes
The bacterial envelope is one of the oldest and most fundamental cellular structures. Yet, many aspects of its diversity and evolutionary history are unknown. In this thesis I have taken advantage of the large available genomic data to investigate the issue through a large-scale phylogenomic and comparative genomic analyses at the level of Bacteria. The two goals of this doctoral work were (i) to identify putative new diderm lineages in the Firmicutes to illuminate the monoderm/diderm transition, and (ii) to elucidate the evolutionary history of the cell envelope in Bacteria and infer its nature in the LBCA. To sum up, the results I obtained during this thesis provide a timely and significant advancement to our understanding of the diversity and evolution of the cell envelope, and on one of the major transitions in the history of Bacteria, that between monoderms and diderms
