Library research support in Queensland : a survey

University libraries worldwide are reconceptualising\ud
the ways in which they support the research agenda\ud
in their respective institutions. This paper is based\ud
on a survey completed by member libraries of the\ud
Queensland University Libraries Office of Cooperation\ud
(QUL OC), the findings of which may be informative\ud
for other university libraries. After briefly examining\ud
major emerging trends in research support, the\ud
paper discusses the results of the survey specifically\ud
focussing on support for researchers and the research\ud
agenda in their institutions. All responding libraries offer\ud
a high level of research support, however, eResearch\ud
support, in general, and research data management\ud
support, in particular, have the highest variance among\ud
the libraries, and signal possible areas for growth. Areas\ud
for follow-up, benchmarking and development are\ud
suggested
And then came complex project management (revised)

The subject of management is renowned for its addiction to fads and fashions. Project Management is no exception. The issue of interest for this paper is the establishment of standards in the area, specifically the 'College of Complex Project Managers' and their 'competency standard for complex project managers'. Both the college and the standard have generated significant interest in the Project\ud
Management community. Whilst the need for development of the means to manage complex projects is acknowledged, a critical evaluation show significant flaws in the definition of complex in this case, the process by which the College and its standard have emerged, and the content of the standard. If Project Management is to continue to develop as a profession, it will need an evidence-based approach to the generation of knowledge and standards. The issues raised by the evaluation provide the case for a portfolio of research that extends the existing bodies of knowledge into large-scale complicated (or major) projects. We propose that it would be owned by the practitioner community, rather than focused on one organization. Research questions are proposed that would commence this stream of activity towards an intelligent synthesis of what is required to manage in both complicated and truly complex environments. This is a revised paper previously presented at the 21st IPMA World Congress on Project Management Cracow, Poland
The EBLM project : III. A Saturn-size low-mass star at the hydrogen-burning limit

This work was partially supported by a grant from the Simons Foundation (PI Queloz, grant number 327127).We report the discovery of an eclipsing binary system with mass-ratio q ∼ 0.07. After identifying a periodic photometric signal received by WASP, we obtained CORALIE spectroscopic radial velocities and follow-up light curves with the Euler and TRAPPIST telescopes. From a joint fit of these data we determine that EBLM J0555-57 consists of a sun-like primary star that is eclipsed by a low-mass companion, on a weakly eccentric 7.8-day orbit. Using a mass estimate for the primary star derived from stellar models, we determine a companion mass of 85 ± 4 MJup (0.081 M⊙) and a radius of 0.84+ 0.14 -0.04RJup (0.084 R⊙) that is comparable to that of Saturn. EBLM J0555-57Ab has a surface gravity log g2 =5.50+ 0.03 -0.13 and is one of the densest non-stellar-remnant objects currently known. These measurements are consistent with models of low-mass stars.PostprintPeer reviewe
A simple molecular complex mediates widespread BMP-induced repression during Drosophila development.

The spatial and temporal control of gene expression during the development of multicellular organisms is regulated to a large degree by cell-cell signaling. We have uncovered a simple mechanism through which Dpp, a TGFbeta/BMP superfamily member in Drosophila, represses many key developmental genes in different tissues. A short DNA sequence, a Dpp-dependent silencer element, is sufficient to confer repression of gene transcription upon Dpp receptor activation and nuclear translocation of Mad and Medea. Transcriptional repression does not require the cooperative action of cell type-specific transcription factors but relies solely on the capacity of the silencer element to interact with Mad and Medea and to subsequently recruit the zinc finger-containing repressor protein Schnurri. Our findings demonstrate how the Dpp pathway can repress key targets in a simple and tissue-unrestricted manner in vivo and hence provide a paradigm for the inherent capacity of a signaling system to repress transcription upon pathway activation
Measuring dynamic market selection by persistent scale inefficiencies - applied to EU business services

The paper proposes a new way of analysing the efficiency of dynamic market selection, based on the persistence of scale economies. The persistence of scale-related inefficiencies is used as an indicator for the effectiveness of market selection.
We use a DEA method to construct the productivity frontier by sub-sector and size class, for business services in 13 EU countries. From this we derive scale economies and their development over time. Our results indicate malfunctioning competitive selection. Between 1999 and 2005 we observe a persistence of scale diseconomies, with scale efficiency falling rather than growing over time. In panel regressions we find the distance to the productivity frontier (within and between size classes) to be significantly explained by regulatory policies that hamper entry and exit dynamics and labour adjustment, and by a lack of import penetration and domestic start-ups. The results suggest that policy reform and more market openness may have positive productivity effects. This holds for business services itself, but also wider, because of business services’ large role in intermediary production inputs.
Numerical and analytical modeling of orthogonal cutting : The link between local variables and global contact characteristics

The response of the tool–chip interface is characterized in the orthogonal cutting process by numerical and analytical means and compared to experimental results. We study the link between local parameters (chip temperature, sliding friction coefficient, tool geometry) and overall friction characteristics depicting the global response of the tool–chip interface. Sticking and sliding contact regimes are described.

The overall friction characteristics of the tool are represented by two quantities: (i) the mean friction coefficient qualifies the global response of the tool rake face (tool edge excluded) and (ii) the apparent friction coefficient reflects the overall response of the entire tool face, the effect of the edge radius being included. When sticking contact is dominant the mean friction coefficient is shown to be essentially the ratio of the average shear flow stress along the sticking zone by the average normal stress along the contact zone. The dependence of overall friction characteristics is analyzed with respect to tool geometry and cutting conditions. The differences between mean friction and apparent friction are quantified. It is demonstrated that the evolutions of the apparent and of the mean friction coefficients are essentially controlled by thermal effects. Constitutive relationships are proposed which depict the overall friction characteristics as functions of the maximum chip temperature along the rake face. This approach offers a simple way for describing the effect of cutting conditions on the tool–chip interface response. Finally, the contact length and contact forces are analyzed. Throughout the paper, the consistency between numerical, analytical and experimental results is systematically checked
Minor histocompatibility antigens are expressed in syncytiotrophoblast and trophoblast debris: implications for maternal alloreactivity to the fetus

The fetal semi-allograft can induce expansion and tolerance of antigen-specific maternal T and B cells through paternally inherited major histocompatibility complex and minor histocompatibility antigens (mHAgs). The effects of these antigens have important consequences on the maternal immune system both during and long after pregnancy. Herein, we investigate the possibility that the placental syncytiotrophoblast and deported trophoblastic debris serve as sources of fetal mHAgs. We mapped the expression of four mHAgs (human mHAg 1, pumilio domain-containing protein KIAA0020, B-cell lymphoma 2–related protein A1, and ribosomal protein S4, Y linked) in the placenta. Each of these proteins was expressed in several placental cell types, including the syncytiotrophoblast. These antigens and two additional Y chromosome–encoded antigens [DEAD box polypeptide 3, Y linked (DDX3Y), and lysine demethylase5D] were also identified by RT-PCR in the placenta, purified trophoblast cells, and cord blood cells. Finally, we used a proteomic approach to investigate the presence of mHAgs in the syncytiotrophoblast and trophoblast debris shed from first-trimester placenta. By this method, four antigens (DDX3Y; ribosomal protein S4, Y linked; solute carrier 1A5; and signal sequence receptor 1) were found in the syncytiotrophoblast, and one antigen (DDX3Y) was found in shed trophoblast debris. The finding of mHAgs in the placenta and in trophoblast debris provides the first direct evidence that fetal antigens are present in debris shed from the human placenta. The data, thus, suggest a mechanism by which the maternal immune system is exposed to fetal alloantigens, possibly explaining the relationship between parity and graft-versus-host disease.Full Tex
The Role of Recent Admixture in Forming the Contemporary West Eurasian Genomic Landscape.

Over the past few years, studies of DNA isolated from human fossils and archaeological remains have generated considerable novel insight into the history of our species. Several landmark papers have described the genomes of ancient humans across West Eurasia, demonstrating the presence of large-scale, dynamic population movements over the last 10,000 years, such that ancestry across present-day populations is likely to be a mixture of several ancient groups [1-7]. While these efforts are bringing the details of West Eurasian prehistory into increasing focus, studies aimed at understanding the processes behind the generation of the current West Eurasian genetic landscape have been limited by the number of populations sampled or have been either too regional or global in their outlook [8-11]. Here, using recently described haplotype-based techniques [11], we present the results of a systematic survey of recent admixture history across Western Eurasia and show that admixture is a universal property across almost all groups. Admixture in all regions except North Western Europe involved the influx of genetic material from outside of West Eurasia, which we date to specific time periods. Within Northern, Western, and Central Europe, admixture tended to occur between local groups during the period 300 to 1200 CE. Comparisons of the genetic profiles of West Eurasians before and after admixture show that population movements within the last 1,500 years are likely to have maintained differentiation among groups. Our analysis provides a timeline of the gene flow events that have generated the contemporary genetic landscape of West Eurasia
Measurement of the inclusive energy spectrum in the very forward direction in proton-proton collisions at sqrt(s) = 13 TeV

The differential cross section for inclusive particle production as a function of energy in proton-proton collisions at a center-of-mass energy of 13 TeV is measured in the very forward region of the CMS detector. The measurement is based on data collected with the CMS apparatus at the LHC, and corresponds to an integrated luminosity of 0.35 inverse microbarns. The energy is measured in the CASTOR calorimeter, which covers the pseudorapidity region -6.6 &lt; eta &lt; -5.2. The results are given as a function of the total energy deposited in CASTOR, as well as of its electromagnetic and hadronic components. The spectra are sensitive to the modeling of multiparton interactions in pp collisions, and provide new constraints for hadronic interaction models used in collider and in high energy cosmic ray physics
Relations between problem behaviors, perceived symptom severity and parenting in adolescents and emerging adults with ASD

Research in parents of youngsters with Autism Spectrum Disorder (ASD) increasingly documents associations between children's problem behaviors and symptom severity and more dysfunctional and less adaptive parenting behaviors. However, the mechanisms underlying these associations have not been examined thoroughly. This study examines the mediating role of parental need frustration in the relation between child maladjustment (i.e., problem behavior and autism severity) and parenting behavior (i.e., controlling and autonomy-supportive parenting). The sample included 95 parents of adolescents/emerging adults with ASD (M _age_ = 18.8 years, _SD_ = 2.3). Parents completed questionnaires assessing their parenting strategies and psychological need frustration as well as the internalizing and externalizing problem behaviors and autism severity of their child. Results indicate that the association between externalizing problems and controlling parenting was partially mediated by need frustration. This suggests that externalizing problems go together with lower feelings of parent-child closeness, lower parental competence, and a decreased sense of volitional functioning, feelings that, in turn, relate to more controlling strategies. Symptom severity has a direct negative association with autonomy support, suggesting that parents lower their autonomy support when their child has high levels of autism symptoms, without experiencing these symptoms as a threat to their own psychological needs
The superconformal index and an elliptic algebra of surface defects.

In this paper we continue the study of the superconformal index of four-dimensional   N  =2 theories of class   S  in the presence of surface defects. Our main result is the construction of an algebra of difference operators, whose elements are labeled by irreducible representations of A N −1. For the fully antisymmetric tensor representations these difference operators are the Hamiltonians of the elliptic Ruijsenaars-Schneider system. The structure constants of the algebra are elliptic generalizations of the Littlewood-Richardson coefficients. In the Macdonald limit, we identify the difference operators with local operators in the two-dimensional TQFT interpretation of the superconformal index. We also study the dimensional reduction to difference operators acting on the three-sphere partition function, where they characterize supersymmetric defects supported on a circle, and show that they are transformed to supersymmetric Wilson loops under mirror symmetry. Finally, we compare to the difference operators that create ’t Hooft loops in the four-dimensional   N  =2* theory on a four-sphere by embedding the three-dimensional theory as an S-duality domain wall
Implications of conformal invariance in momentum space.

We present a comprehensive analysis of the implications of conformal invariance for 3-point functions of the stress-energy tensor, conserved currents and scalar operators in general dimension and in momentum space. Our starting point is a novel and very effective decomposition of tensor correlators which reduces their computation to that of a number of scalar form factors. For example, the most general 3-point function of a conserved and traceless stress-energy tensor is determined by only five form factors. Dilatations and special conformal Ward identities then impose additional conditions on these form factors. The special conformal Ward identities become a set of first and second order differential equations, whose general solution is given in terms of integrals involving a product of three Bessel functions (‘triple-K integrals’). All in all, the correlators are completely determined up to a number of constants, in agreement with well-known position space results. In odd dimensions 3-point functions are finite without renormalisation while in even dimensions non-trivial renormalisation in required. In this paper we restrict ourselves to odd dimensions. A comprehensive analysis of renormalisation will be discussed elsewhere
Physics Without Physics

David Finkelstein was very fond of the new information-theoretic paradigm of physics advocated by John Archibald Wheeler and Richard Feynman. Only recently, however, the paradigm has concretely shown its full power, with the derivation of quantum theory (Chiribella et al., Phys. Rev. A 84:012311, 2011; D'Ariano et al., 2017) and of free quantum field theory (D'Ariano and Perinotti, Phys. Rev. A 90:062106, 2014; Bisio et al., Phys. Rev. A 88:032301, 2013; Bisio et al., Ann. Phys. 354:244, 2015; Bisio et al., Ann. Phys. 368:177, 2016) from informational principles. The paradigm has opened for the first time the possibility of avoiding physical primitives in the axioms of the physical theory, allowing a refoundation of the whole physics over logically solid grounds. In addition to such methodological value, the new information-theoretic derivation of quantum field theory is particularly interesting for establishing a theoretical framework for quantum gravity, with the idea of obtaining gravity itself as emergent from the quantum information processing, as also suggested by the role played by information in the holographic principle (Susskind, J. Math. Phys. 36:6377, 1995; Bousso, Rev. Mod. Phys. 74:825, 2002). In this paper I review how free quantum field theory is derived without using mechanical primitives, including space-time, special relativity, Hamiltonians, and quantization rules. The theory is simply provided by the simplest quantum algorithm encompassing a countable set of quantum systems whose network of interactions satisfies the three following simple principles: homogeneity, locality, and isotropy. The inherent discrete nature of the informational derivation leads to an extension of quantum field theory in terms of a quantum cellular automata and quantum walks. A simple heuristic argument sets the scale to the Planck one, and the observed regime is that of small wavevectors ..
Particle flow SMC-PHD filter for audio-visual\ud
multi-speaker tracking. Proc. 13th International Conference on Latent Variable Analysis and Signal Separation(LVA/ICA 2017), Grenoble, France, February 21-23, 2017.

Sequential Monte Carlo probability hypothesis density (SMC-\ud
PHD) filtering has been recently exploited for audio-visual (AV) based\ud
tracking of multiple speakers, where audio data are used to inform the\ud
particle distribution and propagation in the visual SMC-PHD filter. However, the performance of the AV-SMC-PHD filter can be affected by the\ud
mismatch between the proposal and the posterior distribution. In this paper, we present a new method to improve the particle distribution where\ud
audio information (i.e. DOA angles derived from microphone array measurements) is used to detect new born particles and visual information\ud
(i.e. histograms) is used to modify the particles with particle \ud
flow (PF).\ud
Using particle \ud
flow has the benefit of migrating particles smoothly from\ud
the prior to the posterior distribution. We compare the proposed algorithm with the baseline AV-SMC-PHD algorithm using experiments on\ud
the AV16.3 dataset with multi-speaker sequences
A New Approach to Commutative Watermarking-Encryption

We propose a new approach to commutative watermarking-encryption (CWE). A permutation cipher is used to encrypt the multimedia data, which leaves the global statistics of the multimedia data intact. Therefore, any non-localized watermarking scheme that depends only on global statistics of the multimedia data can be combined with the permutation cipher to form a CWE scheme. We demonstrate this approach by giving a concrete implementation, which manipulates the global histogram to achieve watermark embedding/detection
Preliminary results for RR Lyrae stars and classical Cepheids from VISTA Magellanic Cloud (VMC) survey

The Vista Magellanic Cloud (VMC, PI M.R. Cioni) survey is collecting K S -band time series photometry of the system formed by the two Magellanic Clouds (MC) and the "bridge" that connects them. These data are used to build K S -band light curves of the MC RR Lyrae stars and Classical Cepheids and determine absolute distances and the 3D geometry of the whole system using the K-band period luminosity ( PLKs), the period-luminosity-color ( PLC) and the Wesenhiet relations applicable to these types of variables. As an example of the survey potential we present results from the VMC observations of two fields centered respectively on the South Ecliptic Pole and the 30 Doradus star forming region of the Large Magellanic Cloud. The VMC Ks -band light curves of the RR Lyrae stars in these two regions have very good photometric quality with typical errors for the individual data points in the range of ~0.02 to 0.05 mag. The Cepheids have excellent light curves (typical errors of ~0.01 mag). The average K S magnitudes derived for both types of variables were used to derive PLK S relations that are in general good agreement within the errors with the literature data, and show a smaller scatter than previous studies
Flat modules over valuation rings

Let $R$ be a valuation ring and let $Q$ be its total quotient ring. It is
proved that any singly projective (respectively flat) module is finitely
projective if and only if $Q$ is maximal (respectively artinian). It is shown
that each singly projective module is a content module if and only if any
non-unit of $R$ is a zero-divisor and that each singly projective module is
locally projective if and only if $R$ is self injective. Moreover, $R$ is
maximal if and only if each singly projective module is separable, if and only
if any flat content module is locally projective. Necessary and sufficient
conditions are given for a valuation ring with non-zero zero-divisors to be
strongly coherent or $\pi$-coherent. A complete characterization of
semihereditary commutative rings which are $\pi$-coherent is given. When $R$ is
a commutative ring with a self FP-injective quotient ring $Q$, it is proved
that each flat $R$-module is finitely projective if and only if $Q$ is perfect
Observation of the decay B0s→D¯0φ

First observation of the decay B0s→D¯¯¯0ϕ is reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. The significance of the signal is 6.5 standard deviations. The branching fraction is measured relative to that of the decay B0s→D¯¯¯0K¯¯¯⁎0 to be B(B0s→D¯¯¯0ϕ)B(B0s→D¯¯¯0K¯¯¯⁎0)=0.069±0.013 (stat)±0.007 (syst). The first measurement of the ratio of branching fractions for the decays B0s→D¯¯¯0K¯¯¯⁎0 and B0→D¯¯¯0K⁎0 is found to be B(B0s→D¯¯¯0K¯¯¯⁎0)B(B0→D¯¯¯0K⁎0)=7.8±0.7 (stat)±0.3 (syst)±0.6 (fs/fd), where the last uncertainty is due to the ratio of the B0s and B0 fragmentation fractions
The geometry of Minkowski spaces -- a survey. Part I

We survey elementary results in Minkowski spaces (i.e. finite dimensional
Banach spaces) that deserve to be collected together, and give simple proofs
for some of them. We place special emphasis on planar results. Many of these
results have often been rediscovered as lemmas to other results. In Part I we
cover the following topics: The triangle inequality and consequences such as
the monotonicity lemma, geometric characterizations of strict convexity,
normality (Birkhoff orthogonality), conjugate diameters and Radon curves,
equilateral triangles and the affine regular hexagon construction, equilateral
sets, circles: intersection, circumscribed, characterizations, circumference
and area, inscribed equilateral polygons.Comment: 56 pages, 28 figure
