We report a detection of the baryon acoustic oscillation feature in the three-dimensional correlation function of the transmitted flux fraction in the Lya forest of high-redshift quasars. The study uses 48 640 quasars in the redshift range 2.1 = z = 3.5 from the Baryon Oscillation Spectroscopic Survey of the third generation of the Sloan Digital Sky Survey. At a mean redshift z = 2.3, we measure the monopole and quadrupole components of the correlation function for separations in the range (...) 20 h-1 Mpc < r < 200 h-1 Mpc. A peak in the correlation function is seen at a separation equal to times the distance expected for the BAO peak within a concordance.CDM cosmology. This first detection of the BAO peak at high redshift, when the universe was strongly matter dominated, results in constraints on the angular diameter distance DA and the expansion rate H at z = 2.3 that, combined with priors on H0 and the baryon density, require the existence of dark energy. Combined with constraints derived from cosmic microwave background observations, this result implies H = km s-1 Mpc-1, indicating that the time derivative of the cosmological scale parameter.a = H/ is significantly greater than that measured with BAO at z ∼ 0.5. This demonstrates that the expansion was decelerating in the range 0.7 < z < 2.3, as expected from the matter domination during this epoch. Combined with measurements of H0, one sees the pattern of deceleration followed by acceleration characteristic of a dark-energy dominated universe. © 2013 ESO. (shrink)

We present a high statistics measurement of the branching ratio for the decay τ-→π-μτ using data obtained with the Mark II detector at the SLAC e+e- storage ring SPEAR. We have used events from the center-of-mass energy region 3.52 to 6.7 GeV to determine that B=0.117±0.004±0.018. From electron-muon events in the same data sample, we have determined that B B=0.66±0.03±0.11. We present measurements of the mass and spin of the τ and the mass of the τ neutrino based, for the (...) first time, on a hadronic decay mode of the τ. © 1982. (shrink)

The active debate about the return of incidental or secondary findings in research has primarily focused on return to research participants, or in some cases, family members. Particular attention has been paid to return of genomic findings. Yet, research may generate other types of findings that warrant consideration for return, including findings related to the pathology of donated biospecimens. In the case of deceased biospecimen donors who are also organ and/or tissue transplant donors, pathology incidental findings may be relevant not (...) to family members, but to potential organ or tissue transplant recipients. This paper will describe the ethical implications of pathology incidental findings in the Genotype-Tissue Expression (GTEx) project, the process for developing a consensus approach as to if/when such findings should be returned, possible implications for other research projects collecting postmortem tissues and how the scenario encountered in GTEx fits into the larger return of results/incidental findings debate.

In his aesthetic reflections, Hegel identifies the Judaic Psalms, which he calls sacred poetry, as the core of the sublime. While it has often been suggested that Hegel showed little interest in the notion of sublimity, Ibarra B. contends that this interpretation is misleading and warrants further elucidation. Introducing a new perspective, he argues that a careful examination of Hegel's remarks on sacred poetry reveals a critique of the notion of agency as depicted in the Psalms. By revisiting Hegel's early (...) works predating 1800 and his dispute with Kant's concept of freedom, this studyoffers a practical account of Hegel's view on sublime art within the framework of his philosophy of love.

The paper illustrates how organic chemists dramatically altered their practices in the middle part of the twentieth century through the adoption of analytical instrumentation - such as ultraviolet and infrared absorption spectroscopy and nuclear magnetic resonance spectroscopy - through which the difficult process of structure determination for small molecules became routine. Changes in practice were manifested in two ways: in the use of these instruments in the development of 'rule-based' theories; and in an increased focus on synthesis, at the expense (...) of chemical analysis. These rule-based theories took the form of generalizations relating structure to chemical and physical properties, as measured by instrumentation. This 'Instrumental Revolution' in organic chemistry was two-fold: encompassing an embrace of new tools that provided unprecedented access to structures, and a new way of thinking about molecules and their reactivity in terms of shape and structure. These practices suggest the possibility of a change in the ontological status of chemical structures, brought about by the regular use of instruments. The career of Robert Burns Woodward (1917-1979) provides the central historical examples for the paper. Woodward was an organic chemist at Harvard from 1937 until the time of his death. In 1965, he won the Nobel Prize in Chemistry. (shrink)

Illustrations: 13 B/w & 1 Colour Illustrations Description: The frontiers of Traditional Knowledge and Science have long attracted the minds of scientists, theologians, intellectuals and students, who have been arguing both their similarities and dissimilarities, apparent contradictions, and the possibility of an ultimate harmony between the two. In ancient and medieval India - as in much of the Non-Western world - there was only one word for tradition and science, namely, vidya. Vidya encompassed what in the modern historically-sensitive inquiries is (...) called 'knowledge-systems.' However, in the modern West, placing Science and Tradition side-by-side has become something of an anathema, for many in the post-Enlightenment era regard Tradition to be a leftover from the Dark Ages. Science, in contrast, with its systematic approach to studying and understanding of all there is, has been considered to be unassailable. But even this impenetrable divide may be showing signs of rupture in the twenty-first century : there is now growing evidence of a line of continuity and creative engagement in a 'third space' between Science and Traditional Knowledge. Individuals and learned organizations are making enormous contributions in this interactive exploration. The Sir John Templeton Foundation, based in Philadelphia, USA, is one such international organization. Professor B.V. Subbarayappa is one such eminent scholar who has relentlessly pursued, and in his quiet way stimulated, the fusion of disparate minds in this area. He is hailed as a pioneer in the History and Philosophy of Science movement in India. His contributions in this field are without match and have earned him a name among scientists, science historians, philosophers and intellectuals all over the world. His monumental work and his sheer humanity have inspired the Editors of this volume to find a way to honour him. Scholars of various persuasions from around the world have contributed exploratory, specialist and dialogic essays toward this conversation of Science and Tradition. A biographical sketch with a comprehensive Bibliography (first-ever) of Prof Subbarayappa is also featured in the Introductory essay. Professor--D.P. Chattopadhyaya and J.N. Mohanty have offered prefatory comments of their own. Given the extensive range of topics discussed, both specialists and lay readers will doubtless gain a deeper understanding of the relationship between Science and Tradition in a cross-cultural context, and hopefully be inspired to develop respect for knowledge across these two frontiers.

According to both deontologists and consequentialists, if there is a reason to promote the general happiness – or to promote any other state of affairs unrelated to one's own projects or self-interest – then the reason must apply to everyone. This view seems almost self-evident; to challenge it is to challenge the way we think of moral reasons. I contend, however, that the view depends on the unwarranted assumption that the only way to restrict the application scope of a reason (...) for action is by restricting it to those agents whose interests or projects are involved in the reason. In fact normative theories may coherently restrict application scopes in other ways. Thus we must take seriously the possibility that the reason to promote the general happiness, although genuine, does not apply to everyone. (shrink)

In his article ‘God and Probability’, 1 Hugh Mellor introduced the notion of the ‘bridge-hand fallacy’, allegedly committed by those who think they can appeal to probabilities in arguments for design. I should like to give this notion another airing, partly because of its recent criticism in two interesting books - R. G. Swinburne' The Existence of God and D. J. Bartholomew's God of Chance - and partly because it seems worth asking how it fares in relation to the most (...) recent examples of design argument, namely those which appeal to the so-called ‘anthropic principle’ in cosmology.

This volume brings the remarkable writings of Russian liberal thinker Boris Nikolaevich Chicherin (1828–1904) to English-language readers for the first time. The collection includes key essays in which Chicherin addresses the central political and social problems that confronted Russia from 1855 to the opening years of the twentieth century. Chicherin’s ideological alternatives to the Bolshevik plan for revolutionary transformation of Russia not only provide valuable historical insights, but also are highly relevant to current political discussion of liberalism in Russia and (...) in the West. In a comprehensive introduction to the book, G. M. Hamburg discusses the development of Chicherin’s thought and places it in historical context. Chicherin, Hamburg says, was a powerful and sophisticated but often misunderstood defender of civil and political rights. Like his fellow liberals in Russia, Chicherin was heavily influenced by German idealism and particularly by Hegel. He departed from many, however, in favoring a market economy and advocating that reform efforts be tailored to local conditions and traditions. In this collection Chicherin explores such contemporary issues as the abolition of serfdom, Russian education, and the need for a constitution. He also tackles broad philosophical problems—the nature of liberty and equality, styles of political discourse—and comments on such philosophers as Plato, Aristotle, More, Machiavelli, Montesquieu, Hegel, and Marx.

The history of Athenian relations with Sicily in the fifth century is beset with difficulties; and no part of it, perhaps, is more obscure than the story of what is commonly known as the First Sicilian Expedition, which set sail from Athens in the late summer of 427 under Laches, and was reinforced under Pythodorus, Sophocles and Eurymedon in the winter of 426.

A major distinction in the social organization of ant societies is the number of reproductive queens that reside in a single colony. The fire ant Solenopsis invicta exists in two distinct social forms, one with colonies headed by a single reproductive queen and the other containing several to hundreds of egg‐laying queens. This variation in social organization has been shown to be associated with genotypes at the gene Gp‐9. Specifically, single‐queen colonies have only the B allelic variant of this gene, (...) whereas multiple‐queen colonies always have the b variant as well. Subsequent studies revealed that Gp‐9 shares the highest sequence similarity with genes encoding pheromone‐binding proteins (PBPs). In other insects, PBPs serve as central molecular components in the process of chemical recognition of conspecifics. Fire ant workers regulate the number of egg‐laying queens in a colony by accepting queens that produce appropriate chemical signals and destroying those that do not. The likely role of GP‐9 in chemoreception suggests that the essential distinction in colony queen number between the single and multiple‐queen form originates from differences in workers' abilities to recognize queens. Other, closely related fire ant species seem to regulate colony social organization in a similar fashion. BioEssays 27:91–99, 2005. © 2004 Wiley Periodicals, Inc. (shrink)

Among moral attributes true virtue alone is sublime. … [I]t is only by means of this idea [of virtue] that any judgment as to moral worth or its opposite is possible. … Everything good that is not based on a morally good disposition … is nothing but pretence and glittering misery. 1.
