The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

In recent years, images of climate catastrophe have become commonplace. However, Black visions of the confluence of the Anthropocene and the apocalypse have been largely ignored. As we argue in this article, Black social thought offers crucial resources for drawing out the implicit exclusions of dominant representations of climate breakdown and developing an alternative account of the planet’s future. By reading a range of critical race theorists, from Frederick Douglass and W. E. B. Du Bois to Octavia Butler and Ta-Nehisi (...) Coates, we propose a rethinking of the climate apocalypse. The African American theoretical and cultural tradition elaborates an image of the end of the world that emphasises the non-revelatory nature of climate catastrophe, warns against associating collapse with rebirth, and articulates a mode of maroon survivalism in which the apocalypse is an event to be endured and escaped rather than fatalistically expected or infinitely delayed.

This volume should prove of value to the instructor who desires to stimulate ethical discussion among undergraduates. Its concern is the perennial debate between deontologists and teleologists over what is right and what is wrong in particular cases. A straightforward introduction by the editor defines the problem and summarizes the positions taken in the readings. The selections are intelligent and well-arranged. From the extremes of Kant and Sidgwick, the reader proceeds to twentieth century efforts at compromise. There is a section (...) from Ross on prima facie obligations. Rule-utilitarianism is advocated by J. Harrison and attacked by J. J. C. Smart. A provocative piece by C. Strange offers a possible answer to Smart. The final selection is R. Brandt's "Toward a Credible Form of Utilitarianism" with its attempted reduction of rule-to act-utilitarianism. A good, short bibliographic essay completes this volume.--E. S. P. (shrink)

Ce travail pose la question des critères de la „progression biologique“ , d'après les documents fossiles, dans le monde des organismes, c'est-à-dire de ce perfectionnement qui ne s'arrête pas à l'intérieur du cadre d'un phylum donné, comme le „perfectionnement de l'adaptation“, mais qui conduit, au-de-là de phylums de rang différent, à des types supérieurs, par exemple, des Poissons pas les Amphibies et les Reptiles jusqu'aux Mammifères ou aux Oiseaux. Deux groupes de critères y sont recensés en détail, leur contenu est (...) exposé, et on les examine pour voir s'ils caractérisent sans ambiguïté la „progression biologique“. Le premier groupe comprend les critères de „différenciation croissante“ et „d'intégration harmonique”. Ils sont fondés sur la différenciation morphophysiologique ou plus exactement sur la „totalité” des organismes, c'est-à-dire leur multiplicité dans l'unité. Le second groupe de critères, à savoir „indépendance croissante du milieu” et „autonomie individuelle croissante”, part des relations de l'organisme au milieu et aux autres formes vivantes et souligne la „subsistence” des individus, c'est-à-dire leur plus ou moins grande indépendence ou leur stabilité interne. Comme „totalité” et „subsistence” sont les éléments décisifs d'une définition biologique de l'individu, on peut dire que la „progression biologique“ d'un organisme est d'autant plus élevée que sa totalité et subsistence et par là son être individuel sont plus accusés.Tous les critères mentionnés ne sont pas uniformes. Les motifs de leur imprécision sont divers. Tout d'abord, il n'y a pas encore de définition unique et complète de l'individu biologique, de sorte qu'on ne peut circonscrire d'une manière univoque ce qui confère à un organisme une individualité plus forte ou moins forte. Ensuite les lignées au-delà desquelles s'accomplissent des perfectionnements, et dont l'une reste intérieur au phylum , tandis que l'autre le transcende , sont entrelacées si intimement et d'une façon si particulière qu'elles ne se laissent pas séparer franchement et décrire rigoureusement selon leurs signes distinctifs. Tout représentant d'un phylum, peu importe son palier, est en effet nécessairement inséré dans un milieu et en quelque façon spécialisé. Il n'existe pas des types à caractères phylétiques purs, qui ne montrent dans aucune direction un „perfectionnement de l'adaptation”, mais seulement des marques caractéristiques de la „progression biologique”. Enfin nous ne connaissons pas les restes fossiles que le développement ou la formation des grands phylums du règne animal, à savoir du rameau des Vertébrés et des divers groupes des Invertébrés, mais non pas le plus intéressant et le plus important, leur „progression biologique” jusqu'au degré d'organisation qu'ils présentent déjà à l'époque du Silurien ou plutôt du Cambrien. C'est cela seulement qui permettrait une vue plus profonde sur la nature de la „progression biologique”.Die Arbeit stellt die Frage nach den Kriterien des fossil belegten Biologischen Aufstiegs” der Organismenwelt, d.h. derjenigen Vervollkommnung, die sich nicht innerhalb des Rahmens eines gegebenen Bauplans hält, wie die „Anpassungsvervollkommnung”, sondern über verschiedenrangige Baupläne hinweg zu höheren Typen führt, z.B. von den Fischen über die Amphibien und Reptilien zu den Säugern bzw. Vögeln. Ausführlich werden zwei Gruppen von Kriterien besprochen, ihr Inhalt dargelegt und ihre Eindeutigkeit zur Charakterisierung des „Biologischen Aufstiegs” untersucht. Die erste Gruppe umfasst die Kriterien der „zunehmenden Differenzierung” und „harmonischeren Integration”. Diese legen die morphologisch-physiologische Differenzierung oder genauer die „Ganzheit” der Organismen zugrunde, d.h. ihre Vielheit in der Einheit. Die zweite Kriteriengruppe, nämlich „zunehmende Umweltunabhängigkeit” und „zunehmende individuelle Autonomie”, geht von den Beziehungen des Organismus zur Umwelt und zu andern Lebensformen aus und betont die „Subsistenz” der Individuen, d.h. ihr grösseres oder geringeres Losgelöstsein oder ihre Selbständigkeit. Da nun „Ganzheit” und „Subsistenz” die entscheidenden Elemente einer biologischen Definition des Individuums sind, lässt sich sagen, dass der „Biologische Aufstieg” eines Organismus um so höher ist, je stärker seine Ganzheit und Subsistenz und damit sein Individuumsein ist.Eindeutigkeit kommt allen genannten Kriterien nicht zu. Die Gründe für ihre Unschärfe sind verschiedener Art. Zunächst gibt es noch keine eindeutige und vollständige Definition des biologischen Individuums, so dass sich nicht eindeutig umreissen lässt, was einem Organismus eine stärkere oder weniger starke Individualität verleiht. Dann sind die Linien, über die sich Vervollkommnungen vollziehen und von denen die eine innerhalb des Bauplans bleibt , die andere aber über ihn hinausführt so innig und in so eigenartiger Weise miteinander verflochten, dass sie sich nicht sauber scheiden und in ihren charakteristischen Merkmalen genau beschreiben lassen. Jeder Vertreter eines Bauplans, ganz gleich von welcher Ranghöhe, ist nämlich notwendig in eine Umwelt eingepasst und irgendwie spezialisiert. Es gibt keine Typen mit reinen Bauplanmerkmalen, die nach keiner Richtung hin eine „Anpassungsvervollkommnung”, sondern nur Merkmale des „Biologischen Aufstiegs” aufweisen. Schliesslich kennen wir fossil nur die Entfaltung oder Ausgestaltung der Grossbaupläne des Tierreichs, nämlich des Wirbeltierstammes und der verschiedenen Gruppen der Wirbellosen, nicht aber das Interessanteste und Wichtigste, nämlich ihren „Biologischen Aufstieg” zu der organisatorischen Höhe, mit der sie sich im Silur bzw. im Kabrium bereits vorstellen. Das erst würde einen tieferen Einblick in das Wesen des „Biologischen Aufstiegs” vermitteln.This article deals with the question of the criteria for the “biological ascent” of the organic world, resting on fossil evidence. That is, of that improvement which is not only restricted to the framework of a given “general structure” as is the “improvement of adaptation”, but which also leads beyond general structures of differentiated levels to a higher type,e.g. from the fishes through the amphibians and reptiles to the mammals or birds. Two groups of criteria are discussed at length, their content exposed and their univocity for the characterisation of this “biological ascent” is examined. The first group includes the criteria of “increasing differentiation” and “more harmonious integration”. The basis for these is the morphological-physiological differentiation, or more exactly, the “totality” of the organisms,i.e., their variety-in-unity. The second group of criteria, “increasing independence of environment” and “increasing individual autonomy”, is derived from the relationships of the organism to its environment and to other living forms, and stresses the “subsistence” of individuals,i.e., their greater or lesser degree of independence or self-sufficiency. Now since “totality” and “subsistence” are the decisive elements in a biological definition of the individual, it may be said that the “biological ascent” of an organism is higher, the more perfect its totality and subsistence and therefore its individuality is.The criteria mentioned are not univocal. The reasons for this lack of clarity are varied. First of all, there is no univocal and complete definition of the biological individual, so that it cannot be exactly stated just what gives an organism a more or less perfect individuality. Then the lines, along which improvements are made, and according to which the one remains within the general structure and the other goes beyond the general structure , are so intimately and singularly bound together, that they cannot be cleanly distinguished, and their characteristic notes exactly described. For each representative of a general structure, regardless of its level, is necessarily fitted into an environment and somehow or other specialised. There are no types with only notes of the general structure which show in no direction an “improvment of adaption”, but only the signs of “biological ascent”. Finally, we only have fossil evidence for the development or deployment of the “great general structures” of the animal world, namely that of the vertebrates and of the different groups of invertebrates, not for the most interesting and most important, that is, their “biological ascent” to the level of organisation with which they are found in the Silurian or Cambrian periods. Only that would give us a deeper insight into the essence of “biological ascent”. (shrink)

O artigo investiga a possibilidade de pensar a questão da justiça sociopolítica a partir da ideia de alteridade.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

This article introduces practical and theoretical investigations in fields of art and technology related to biotelematics, hybridization and transcultural experimentation based on research carried out over the last four years at the Nucleus of Art and New Organisms (NANO). We will approach this subject by considering three main points of view: field theory (Ascott 1980; Nóbrega 2009); the concept of coherence (Ho 1993; Ho & Popp 1989; Simondon 1980); and the state of connectedness (Ascott 2006). These will act as integrative (...) models for the understanding of an emerging hybrid organic structure presented as an aesthetic organism (Nóbrega 2009). The concept of field theory is applied as a working model for the systemic role of information within the immaterial, invisible, dynamical flow that intercommunicates natural (i.e. humans and other living systems) and artificial (i.e. machine) organisms in the process of invention, as well as in the fruition of artwork. In terms of the concept of coherence, we propose the idea of artworks as transducers of energy; more specifically, as resonators of coherent fields that interconnect the artist and audience in an integrated, dynamical whole. Furthermore, we approach the state of connectedness as a fundamental notion for the dynamics involved in the invention, exhibition and absorption of contemporary artworks. NANO Lab’s involvement with artistic research is not only understood as a physical space for experimentation, but also as an environment in which our practice reflects concepts applied in artistic work. In this sense, we can highlight two theoretical references (other than Roy Ascott’s work) which guide this methodology: Humberto Maturana (2001; Varela & Maturana 1992) and the idea of a conserved ‘autopoiesis’, a systematic medium (space) in which all recursive dynamics of reciprocal interactions occur to sustain the survival of life, processes and systems, and where technology can be conceived as a powerful instrument/medium to expand our knowledge about structural and sensitive coherences within living and non-living systems; and, Jorge de Albuquerque Vieira’s (2006; 2009) approach to art as a type of knowledge related to any process that guarantees the permanence or survival of a system based on three major characteristics for the survival of an open system – sensitivity (to operate information flows), memory (to transfer and retain information), and capability (to elaborate or prepare information according to its needs).
