Using the large scale quasar clustering to constrain flat quintessential universes

description: We search for the most suitable set of cosmological parameters that describes the observable universe. The search includes the possibility of quintessential flat universes, i.e., the analysis is restricted to the determination of the dimensionless matter density and the quintessential parameters, $Ω_{\rm M}$ and $w_{\rm Q}$, respectively. Our study is focused on comparing the position of features at large scales in the density fluctuation field at different redshifts by analysing the evolution of the quasar two-point correlation function. We trace the density field fluctuations at large scales using a large and homogeneous sample of quasars ($\sim$ 38000 objects with 0.3 $\lesssim$ z $\le$ 2.4 and a median $z=1.45$) drawn from the Sloan Digital Sky Survey Data Release Six. The analysis relies on the assumption that, in the linear regime, the length scale of a particular feature should remain fixed at different times of the universe for the proper cosmological model. Our study does not assume any particular comoving length scale at which a feature should be found, but intends to perform a comparison for a wide range of scales instead. This is done by quantifying the amount of overlap among the quasar correlation functions at different times using a cross-correlation technique. The most likely cosmological model is $Ω_{\rm M}=0.21\pm 0.02$ and $w_{\rm Q}=-0.93\pm0.04$, in agreement with previous studies. These constraints are the result of a good overall agreement of the correlation function at different redshifts over scales $\sim 100-300\mpc$. Under the assumption of a flat cosmological model, our results indicate that we are living in a low density universe with a quintessential parameter greater than the one corresponding to a cosmological constant.

Data collection methods for field-based language documentation
Creators: name: Lüpke, Friederike
Publisher: name: Language Documentation and Description
Year: 2014

description: Language documentation, understood as the creation of corpora of annotated and translated speech data in audio and video format, is a newly emerging field of empirical linguistics (Himmelmann 1998, 2006a, Woodbury 2003). Since it owes its existence partly to rapidly evolving digital technologies for the recording, processing, and archiving of these data, it is not surprising that the main methodological focus so far has been on the form a documentation should take. Thus, we find explicit recommendations on such things as suitable data formats, form and content of metadata descriptions, minimally required levels of annotation, and access to and portability of data, (Austin 2006, Bird and Simons 2003, Nathan and Austin 2004, Nathan 2006, Thieberger 2004, Wittenburg et al. 2002). This paper focuses on another central question for good practices in language documentation and description (henceforth LDD): what linguistic goals it can have and how methods of data collection are related to achieving these goals. By doing so, it joins a growing body of literature drawing attention to the various methodological challenges of LDD.

Dying to be counted: the commodification of endangered languages in documentary linguistics

Publisher: name: Language Documentation and Description
Year: 2014

description: The main way in which linguists have responded to the problem of language endangerment has been through a renewed commitment to the task of language documentation. But much of the critical discussion that has been generated by the issue of language endangerment has taken place outside mainstream linguistics, in the related but distinct field of linguistic anthropology. There the focus has been on analyzing the essentially moral discourse that frames language endangerment as a problem worthy of attention and action. But there are also areas within documentary linguistics which could benefit from a more critical approach. In particular, we argue that the discourse of documentary methods is characterised by an embrace of technology as an unquestioned goal, one that in some cases hinders rather than facilitates our thinking about the problems we are trying to solve. In this paper we try to understand, and hence begin to challenge, the social forces that lead documentary linguists to frame their work in the highly patterned ways that they do, even when these are in tension with their larger goals.

Rescuing Maori: the last 40 years

Year: 2014

description: As well as naming the concept, Fishman (1991:87-110) proposed a typology of the status of threatened languages, the Graded Intergenerational Disruption Scale, which assessed the likelihood of language maintenance or death. A decade later, Fishman 2001 daringly invited a number of scholars to comment on and update his scale and case descriptions; while many found the scale to need qualification, all agreed it was a useful selection of significant features and an approximation of the order in which they commonly occur. To illustrate the process of language rescue, I have chosen to describe and analyze the progress of the Māori language in Aotearoa (New Zealand) over the last forty years or so as it moved from a probable Stage 2 to a reasonable approximation of the highest pre-independence Stage 8. In essence, this will show us the possibilities and limitations of a grass roots community-based movement gradually achieving public and government support to regenerate a threatened indigenous language.

Jet energy loss due to multiple scattering in the nucleus
Creators: name: Braun, M. A.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Energy loss of a jet due to multiple collisions in the nuclear target is studied in the framework of the perturbative QCD with an infrared cutoff. An iterational procedure for its calculation is developed, which allows to reliably find up to 16 successive collisions in rescattering. The calculated shift of the scaling variable reaches values of the order 0.1 at medium $x$ and transverse momentum $p$ in the interval 5-10 GeV/c. The shift is found to be independent of the atomic number of the target and energy.

description: In regression analysis, we employ contour projection (CP) to develop a new dimension reduction theory. Accordingly, we introduce the notions of the central contour subspace and generalized contour subspace. We show that both of their structural dimensions are no larger than that of the central subspace Cook [Regression Graphics (1998b) Wiley]. Furthermore, we employ CP-sliced inverse regression, CP-sliced average variance estimation and CP-directional regression to estimate the generalized contour subspace, and we subsequently obtain their theoretical properties. Monte Carlo studies demonstrate that the three CP-based dimension reduction methods outperform their corresponding non-CP approaches when the predictors have heavy-tailed elliptical distributions. An empirical example is also presented to illustrate the usefulness of the CP method.

The remarkable warped and twisted gas disk in NGC 3718

description: We have mapped NGC 3718, a nearby bright galaxy in a loose group, and its companion NGC 3729 in the 21cm line of neutral hydrogen. NGC 3718 is a strikingly unusual galaxy with a strong straight dust lane across the center, peculiar diffuse spiral arms, and an extended disk of neutral hydrogen. Earlier work showed the gas disk to be strongly twisted, warping through edge-on where we see the straight dust lane; stars formed in this gas appear to make up the 'spiral arms'. Our improved maps show a twisted but bisymmetric disk of gas extending to 7arcmin or 35kpc, where the orbital period is roughly 1Gyr. It is surrounded by fragmentary spiral features, and a streamer of gas extending to a cloud lying 12arcmin or 60kpc to the north. We use INSPECTOR, a task in GIPSY, to fit a tilted-ring model interactively to slices through the HI data cube. The apparent major axis swings through 100 degrees from the innermost gas orbits at 30arcsec radius to the outer edge. When viewed in the reference frame of the galaxy's stellar disk, the innermost gas orbits are nearly polar, while the outer rings of gas are tilted at 30-40 degrees. The line of nodes, where the gas orbits pass through the plane of the stellar disk, twists by roughly 90 degrees about the pole. We do not see gas orbiting in the plane of the stellar disk. If we assume that the galaxy's dark halo shares the same midplane, then the observed twist can be explained by differential precession in a dynamical model in which the dark halo is fairly round. The run of tilt with radius is close to what is required for the warped gas disk to precess rigidly in the galaxy's gravitational field without changing its shape. This fact probably accounts for the longevity of the twisted structure.

Sound and unsound practices in documentary linguistics: towards an epistemology for audio
Creators: name: Nathan, David
Publisher: name: Language Documentation and Description
Year: 2014

description: I first noticed problems in linguistic approaches to audio when I began working with multimedia as a member of a team developing curriculum and teaching materials for Australian Indigenous languages during the mid 1990s. I drew the conclusion that linguists make field recordings to serve as evidence, not performance ... Even as evidence, audio was auxiliary, a kind of side-effect; the principal fieldwork products being field notes and the language knowledge absorbed by the researcher. Following the emergence of the field of documentary linguistics in the late 1990s, such audio issues have become harder to ignore. Documentary linguistics, as a response to language endangerment throughout the world, emphasises the collection (i.e. recording) and representation of a range of language events, where the resulting data can be drawn on by various disciplines (Himmelmann 1998, Austin 2010a). Naturally, audio would appear to be its principal medium. This chapter has shown that audio is a necessary, complex, and rich component of the documentation of spoken languages. The broadest aim of the chapter is to stimulate discussion about the goals and purposes of audio in our field.

Language documentation and language typology
Creators: name: Bond, Oliver
Publisher: name: Language Documentation and Description
Year: 2014

description: Typology is a sub-discipline of linguistics originally conceived around the notion that there is a fundamental basic unity underlying the diversity of the world’s languages. Typologists believe that there are certain core properties that languages have in common which can be formulated as generalisations about language in the form of language universals or probabilistic statements about the distribution of language characteristics. At its onset, typology was largely concerned with what is possible in language, that is, discovering what the universals of language might be. However, contemporary typology has a more sophisticated agenda: not simply asking ‘what is possible?’, but examining ‘what is where why?’, with reference to historical and other factors affecting the distribution of language properties (Bickel 2007). In this chapter we are going to explore some core concepts in typology and examine how they relate to language documentation and description. At the end of the chapter you will have a sense of what typology is, some of the principles that underlie it, and understand the symbiotic relationship between the two research fields.

Language documentation and linguistic theory
Creators: name: Sells, Peter
Publisher: name: Language Documentation and Description
Year: 2014

description: This chapter is about the relationship between language documentation and linguistic theory. In this chapter I focus on that part of language documentation which is directed towards grammatical description of a language (‘compiling a grammar’) ... grammatical description presupposes some theory – even basic description involves organisation of the data into categories and parts, and underlyingly this must suppose some linguistic theory. Linguistic theory can help provide a context within which to present a grammatical description ... linguistic theory can and surely must be informed by more and better data (this is Chomsky’s point): this requires that the properties of the data that are fed into theory development are theoretically accurate ... a theoretical outlook can be useful, in the field and ‘at home’ – in terms of presentation of data to linguists, it is important to know what is theoretically interesting or relevant, what might be unusual, etc. Sensitivity to linguistic theory might invite language documenters to look for various phenomena in the language they are studying, without presupposing their necessary existence. So a theoretical outlook can be useful, in the field (in guiding work on the language) and also ‘at home’ (on return to the home institution).

description: Aims. I look for and characterise very wide binaries and multiple systems with projected physical separations larger than s = 0.1 pc, which is generally believed to be a sharp upper limit to the distribution of wide binay semimajor axes. Methods. I investigated in detail 30 Washington Double Stars with angular separations rho > 1000 arcsec. I discarded 23 of them as probably unbound systems based on discordant astrometry, photometry, spectral types, and radial velocities. The remaining seven systems were subject to a comprehensive data compilation and derivation (multi-wavelength photometry, heliocentric distance, multiplicity, age, mass, metallicity, membership in young kinematic group). Results. Of the seven very wide systems, six have projected physical separations larger than the hypothetical cutoff at s = 0.1 pc; four of them have separations s > 0.2 pc. Although there are two systems in young kinematic groups (namely HD 136654 and BD+32 2572 in the Hyades Supercluster, and AU Mic and AT Mic AB in the beta Pictoris moving group), there is not a clear prevalence of young systems (tau < 1 Ga) among these very wide binaries. Finally, I compare the binding energies of the seven systems with those of other weakly bound systems in the field.

Language documentation and archiving: from disk space to MySpace
Creators: name: Nathan, David
Publisher: name: Language Documentation and Description
Year: 2014

description: The Endangered Languages Archive at SOAS is responding to the needs of digital archiving in language documentation and description by exploiting social networking technologies to redefine the archive as a forum or a platform for data providers and users to negotiate about, and to exchange, data. Romaine (2006) has noted that intergenerational transmission may soon be supplanted by institutional learning for many endangered languages. In the longer term, however, documentary corpora and the archives that hold them will become the key vectors of transmission for many endangered and extinct languages. Therefore, the theory and practice of documentation, and the methodologies and capabilities of language archives, will play a crucial role in the future states of many human languages. At ELAR, we believe that we exist in a time when digital preservation practices have rapidly matured and can now be subsumed to an understanding that we must function as the hosts of an important component of human heritage. Management of non-preservation functions will be largely handed over to depositors and users. Tomorrow’s digital language archiving is not about technology but about relationships and commitments.

We present the design and a full characterisation of a CMOS pixel test structure able to withstand doses in excess of 1 MRad. Data collected with electron beams at various energies of interest in electron microscopy are compared to predictions of simulation and to 1.5 GeV electron data to disentagle the effect of multiple scattering. The point spread function measured with 300 keV electrons is (8.1 +/- 1.6) micron for 10 micron pixel and (10.9 +/- 2.3) micron for 20 micron pixels, respectively, which agrees well with the values of 8.4 micron and 10.5 micron predicted by our simulation.

The role of magnetic fields for planetary formation

Publisher: name: arXiv
Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The role of magnetic fields for the formation of planets is reviewed. Protoplanetary disc turbulence driven by the magnetorotational instability has a huge influence on the early stages of planet formation. Small dust grains are transported both vertically and radially in the disc by turbulent diffusion, counteracting sedimentation to the mid-plane and transporting crystalline material from the hot inner disc to the outer parts. The conclusion from recent efforts to measure the turbulent diffusion coefficient of magnetorotational turbulence is that turbulent diffusion of small particles is much stronger than naively thought. Larger particles -- pebbles, rocks and boulders -- get trapped in long-lived high pressure regions that arise spontaneously at large scales in the turbulent flow. These gas high pressures, in geostrophic balance with a sub-Keplerian/super-Keplerian zonal flow envelope, are excited by radial fluctuations in the Maxwell stress. The coherence time of the Maxwell stress is only a few orbits, where as the correlation time of the pressure bumps is comparable to the turbulent mixing time-scale, many tens or orbits on scales much greater than one scale height. The particle overdensities contract under the combined gravity of all the particles and condense into gravitationally bound clusters of rocks and boulders. These planetesimals have masses comparable to the dwarf planet Ceres. I conclude with thoughts on future priorities in the field of planet formation in turbulent discs.

Language documentation and language policy
Creators: name: Sallabank, Julia
Publisher: name: Language Documentation and Description
Year: 2014

description: Language policy is any decision that is made about language. Policies may be conscious or unconscious, explicit or implicit: for example, state education policy may not mention language at all, but may assume that the medium of education is the national language. Language policy can be planned or unplanned, but is no less a policy for being unthinking ... Language policy can be formulated and implemented at any level: for example, some language decisions might relate only to punctuation, whereas a broader national policy might focus on which language(s) are officially recognised for use in national or political life. Because language contact situations are often not equal, languages are in dominant and subordinate positions. As linguists we ... may have more effect on language policy at grass-roots level because that is the level that we are working at. As we have external contacts and knowledge of other contexts, we can form a bridge between communities. We may be called on to advise on language policy, or to mediate between local groups and government authorities. For all these reasons, it is essential for linguists to gain an awareness of issues involved in language policy-making, in order to be prepared.

description: The paper analyzes the phenomenon of turbulent thermal diffusion in the Earth atmosphere, its relation to the turbulent diffusion and its potential impact on aerosol distribution. This phenomenon was predicted theoretically more than 10 years ago and detected recently in the laboratory experiments. This effect causes a non-diffusive flux of aerosols in the direction of the heat flux and results in formation of long-living aerosol layers in the vicinity of temperature inversions. We demonstrated that the theory of turbulent thermal diffusion explains the GOMOS aerosol observations near the tropopause (i.e., the observed shape of aerosol vertical profiles with elevated concentrations located almost symmetrically with respect to temperature profile). In combination with the derived expression for the dependence of the turbulent thermal diffusion ratio on the turbulent diffusion, these measurements yield an independent method for determining the coefficient of turbulent diffusion at the tropopause. We evaluated the impact of turbulent thermal diffusion to the lower-troposphere vertical profiles of aerosol concentration by means of numerical dispersion modelling, and found a regular upward forcing of aerosols with coarse particles affected stronger than fine aerosols.

Documenting sign languages
Creators: name: Schembri, Adam
Publisher: name: Language Documentation and Description
Year: 2014

description: This chapter is an introduction to documentary sign linguistics. I am going to focus mostly on the British Sign Language Corpus Project, based at the Deafness, Cognition and Language Research Centre, University College London — in particular, issues to do with data collection (e.g., the Observer’s Paradox) and the notion of having an open access archive. Unlike some other corpus projects (e.g., the Auslan Archive or the Sign Language of the Netherlands (NGT) Corpus) which received funding specifically for the creation of a corpus, the funding for the BSL Corpus Project comes from a grant by the Economic and Social Research Council (ESRC) as part of a research project to create a corpus while conducting linguistic research into BSL. The key research questions focus primarily on issues related to sociolinguistic variation and change in BSL. Obviously corpus data lends itself rather well to this kind of study, and I will explain below why we have such an interest in variation.

description: We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z=0.24). In addition to PMN J0948+0022 (z=0.585), the first source of this type to be detected in gamma rays, they may form an emerging new class of gamma-ray active galactic nuclei (AGN). These findings can have strong implications on our knowledge about relativistic jets and the unified model of AGN.

Quantifying evolvability in small biological networks

description: We introduce a quantitative measure of the capacity of a small biological network to evolve. We apply our measure to a stochastic description of the experimental setup of Guet et al. (Science 296:1466, 2002), treating chemical inducers as functional inputs to biochemical networks and the expression of a reporter gene as the functional output. We take an information-theoretic approach, allowing the system to set parameters that optimize signal processing ability, thus enumerating each network's highest-fidelity functions. We find that all networks studied are highly evolvable by our measure, meaning that change in function has little dependence on change in parameters. Moreover, we find that each network's functions are connected by paths in the parameter space along which information is not significantly lowered, meaning a network may continuously change its functionality without losing it along the way. This property further underscores the evolvability of the networks.

Twisted cocycles of Lie algebras and corresponding invariant functions
Creators: name: Hrivnak, Jiri
name: Novotny, Petr
Publisher: name: arXiv
Year: 2009
Subjects: subject: Mathematical Physics (math-ph)

description: We consider finite-dimensional complex Lie algebras. Using certain complex parameters we generalize the concept of cohomology cocycles of Lie algebras. A special case is generalization of 1-cocycles with respect to the adjoint representation - so called $(α,β,γ)$--derivations. Parametric sets of spaces of cocycles allow us to define complex functions which are invariant under Lie isomorphisms. Such complex functions thus represent useful invariants - we show how they classify three and four-dimensional Lie algebras as well as how they apply to some eight-dimensional one-parametric nilpotent continua of Lie algebras. These functions also provide necessary criteria for existence of 1-parametric continuous contraction.

Research methods in language documentation
Creators: name: Lüpke, Friederike
Publisher: name: Language Documentation and Description
Year: 2014

description: Language documentation, understood as the creation of corpora of annotated and translated speech data in audio and video format, is a recently developed field of empirical linguistics (Himmelmann 1998, 2006a; Woodbury 2003). Since it owes its existence partly to rapidly evolving digital technologies for the recording, processing, and archiving of these data, it is not surprising that the main methodological focus so far has been on the form a documentation should take. Thus, we find explicit recommendations on such things as suitable data formats, form and content of metadata descriptions, minimally required levels of annotation, and access to and portability of data (Austin 2006; Bird & Simons 2003; Nathan & Austin 2004; Nathan 2006; Thieberger 2004; Wittenburg et al. 2002). This paper focuses on another central question for good practices in language documentation and description (henceforth LDD): what linguistic goals it can have and how methods of data collection are related to achieving these goals. By doing so, it joins a growing body of literature drawing attention to the various methodological challenges of LDD.

description: We report Hubble Space Telescope imaging, obtained 155 and 449 days after the 2006 outburst of the recurrent nova RS Ophiuchi, together with ground-based spectroscopic observations, obtained from the Observatorio Astronómico Nacional en San Pedro Mártir, Baja California, México and at the Observatorio Astrofísico Guillermo Haro, at Cananea, Sonora, México. The observations at the first epoch were used as inputs to model the geometry and kinematic structure of the evolving RS Oph nebular remnant. We find that the modeled remnant comprises two distinct co-aligned bipolar components; a low-velocity, high-density innermost (hour glass) region and a more extended, high-velocity (dumbbell) structure. This overall structure is in agreement with that deduced from radio observations and optical interferometry at earlier epochs. We find that the asymmetry observed in the west lobe is an instrumental effect caused by the profile of the HST filter and hence demonstrate that this lobe is approaching the observer. We then conclude that the system has an inclination to the line of sight of 39$^{+1}_{-10}$ degrees. This is in agreement with the inclination of the binary orbit and lends support to the proposal that this morphology is due to the interaction of the outburst ejecta with either an accretion disk around the central white dwarf and/or a pre-existing red giant wind that is significantly denser in the equatorial regions of the binary than at the poles. The second epoch HST observation was also modeled. However, as no spectra were taken at this epoch, it is more difficult to constrain any model. Nevertheless, we demonstrate that between the two HST epochs the outer dumbbell structure seems to have expanded linearly.

Communities, ethics and rights in language documentation
Creators: name: Austin, Peter K.
Publisher: name: Language Documentation and Description
Year: 2022

description: This chapter is about the general topic of communities, ethics and rights as they relate to language documentation, especially in the context of endangered languages. It is becoming increasingly clear that language documentation projects need more than ethical frameworks, IRBs, statements of ethics and copyright rules. We need a holistic humanistic reflexive practice in carrying out our research (Chambers & Nathan 2009, Dobrin & Berson 2010). We cannot maintain the divisions between ‘us’ as the researcher and ‘them’ as the subjects of research. Fieldwork and language documentation is the ultimate social act in a system of exchange. So, we have to make reciprocity central and not peripheral to what we do, negotiating the conduct of our projects, and outcomes, making the documentation usable and valuable, and giving back in ways that are meaningful and valuable to the communities. Ethical behaviour or even advocacy (supporting communities, writing letters, and advocating for them) is not enough. Ideally, researchers should share their knowledge and be prepared to help communities to support their languages if they wish to do so.

Current issues in language documentation
Creators: name: Austin, Peter K.
Publisher: name: Language Documentation and Description
Year: 2014

description: This chapter is an introduction to the field of linguistics that has come to be known as ‘language documentation’ or ‘documentary linguistics’, covering its main features and giving examples of what it involves. The difference between language documentation and descriptive linguistics is discussed, and an argument presented that the two are complementary activities that can cross-fertilise one another. We then look at some current challenges in the field of language documentation, including issues that are the subject of on-going research. For many researchers and communities, especially those speaking endangered languages, the focus of language research has shifted to a new attention to recording, analysing and preserving records of language in use in ways that can serve a wide range of constituencies, particularly the speaker communities themselves. The field has come about due to a change in the vision of what the goals, methods and outcomes of linguistic research can be, changes in the relations between researchers and those whose languages they study, and has benefited from various developments in technology. A number of challenging issues will need to be addressed as documentary linguistics as a field matures further in the future.

‘Producing’ Thangmi Ritual Texts: Practice, performance and collaboration
Creators: name: Shneiderman, Sara
Publisher: name: Language Documentation and Description
Year: 2014

description: This article considers the methodological, ethical and political issues surrounding what I will call the ‘production’ of Thangmi ritual texts. As an anthropologist, I am currently engaged with community members in the process of creating some of the first written versions of hitherto orally transmitted shamanic recitations in Thangmi, a Tibeto-Burman language spoken in eastern Himalayan parts of Nepal and India. Here I address some of the challenges that scholars may face when working with communities who are actively involved in the process of debating their own relationships with orality and textuality. What do we do when there is no clear consensus on the way forward, no single ‘community perspective’ that we can represent, nor a single form of ‘tradition’ that we can ‘document’? I want to be somewhat provocative and suggest that in such circumstances we have no choice but to fully acknowledge our own complicit roles in producing certain kinds of textual forms, which may or may not bear a direct relation to indigenous forms of practice or performance as we observe them. For this reason, I suggest that the concept of ‘documentation’ may not be adequate to describe the role of scholars in the process of generating...
