description: Much of the animal feed in the United Kingdom is consumed as compound feed. Government support policy has a direct effect on consumption of compound feed and use of various ingredients in the composition of compound feed. The objective of this study was to analyze this relationship, and to project to 1980 total compound feed consumption and use of various ingredients. Three alternative policies were analyzed: deficiency payments, variable import levies, and European Community membership. Results of the study indicated an increased use of compound feed by 1980. The increase would be greatest with deficiency payments and least with EC entry. Major shifts in the composition of compound feed are likely. Discontinuation of deficiency payments would result in a significant reduction in cereal use, and an increase in the use of grain substitutes and high protein feeds.

description: Dye doping is a promising way to increase the spectral purity of polymer light-emitting diodes (LEDs). Here we analyze the frequency and field dependence of the complex admittance of Al-Ba-PPV-PEDOT-ITO LEDs with and without dye. We compare the charge carrier mobilities of pristine and dye-doped double-carrier and hole-only (Au replacing Al-Ba) devices. Dye doping is shown to significantly influence the electron mobilities while the hole mobilities are left unchanged and thereby changing the carrier balance in a double carrier device towards that of a hole only device. The minimum in the LED capacitance as function of voltage appears to be an excellent probe for the electron trapping phenomenon underlying the reduction of the mobility.

description: We provide a comprehensive global analysis of Run II top measurements at the LHC in terms of dimension-6 operators. A distinctive feature of the top sector as compared to the Higgs-electroweak sector is the large number of four-quark operators. We discuss in detail how they can be tested and how quadratic terms lead to a stable limit on each individual Wilson coefficient. Predictions for all observables are computed at NLO in QCD. Our SFitter analysis framework features a detailed error treatment and shows that theoretical uncertainties are a limiting factor.

description: We examine the dephasing rate of a Josephson charge qubit system due to background charge fluctuations. We consider single qubit and two-charge traps. The transition probability was controlled to a state where two traps were occupied. The transition probability was affected by the Coulomb blockade effect that occurs between two charge traps. To obtain the dephasing rate, we computed the spectra of random frequency modulation signals. Our results show that the interaction between charge traps suppresses dephasing.

A comprehensive description of multiple observables in heavy-ion collisions at SPS
Creators: name: Renk, Thorsten
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Combining and expanding on work from previous publications, a model for the evolution of ultrarelativistic heavy-ion collisions at the CERN SPS for 158 AGeV beam energy is presented. Based on the assumption of thermalization and a parametrization of the space-time expansion of the produced matter, this model is able to describe a large set of observables including hadronic momentum spectra, correlations and abundancies, the emission of real photons, dilepton radiation and the suppression pattern of charmonia. Each of these obervables provides unique capabilities to study the reaction dynamics and taken together they form a strong and consistent picture of the evolving system. Based on the emission of hard photons, we argue that a strongly interacting, hot and dense system with temperatures above 250 MeV has to be created early in the reaction. Such a system is bound to be different from hadronic matter and likely to be a quark-gluon plasma, and we find that this assumption is in line with the subsequent evolution of the system that is reflected in other observables.

Thinking Strategically: Development of a Library Data Services Plan
Creators: name: McNeill-Harman, Katherine
Publisher: name: Zenodo
Year: 2004

description: Over the past several years, developments in technology and research have changed the ways in which libraries and their users interact with social science data. Moreover, the integrated and interdisciplinary nature of data requires collaboration among departments and organizations, as well as with providers of data related to GIS and scientific applications. These increasing and changing demands on the part of users present challenges for institutions in allocating their limited resources. In order to plan strategically to meet these needs, the MIT Libraries conducted a project to create a 3 year Data Services Plan. The plan contains goals for reference, instruction, collection development, personnel, facilities, computing, evaluation, and implementation. This presentation will describe the process of creating the Data Services Plan, including user studies, staff input, and research among peers in the social science data community. Additionally, it will discuss challenges faced, the development of priorities, and strategies for implementation.
Play Place : An agonistic intervention for Vancouver City Hall

description: The City of Vancouver’s new Department of Agonistics has its sights set on Helena Gutteridge Plaza. Combining the theories of Chantal Mouffe on agonistic public space with the writings of Johan Huizinga on the play-element of human culture, the Department of Agonistics provides a new model for diagnosing and treated failed public spaces. By embracing the playground as a model for agonistic social infrastructure, this project aims to return spaces such as Helena Gutteridge Plaza to the public as sites for spontaneity, expression, and togetherness so that the participatory nature of urban life can be realized and counter-hegemonic narratives may emerge.

description: The post-fire debris flows of 9 January 2018 killed 23 people, destroyed over 130 homes, and caused severe damage to infrastructure in Montecito and Carpinteria, California. Highway 101 was closed for 13 days, significantly impacting transportation and commerce in the region. Collectively, debris flows from this event are comparable in magnitude to the largest documented post-fire debris flows in the state, inundating over 4 km2 of land, and costing the Santa Barbara region over half a billion dollars in debris removal and damages to homes and infrastructure. Here, we document the extent and magnitude of inundation areas, debris- flow volumes, and source areas. Additionally, we describe the atmospheric conditions that generated intense rainfall and use precipitation data to compare debris-flow source areas with spatially associated peak 15-minute rainfall depths. We use a compilation of debris-flow damages to summarize economic impacts associated with the event.
Data Curation and Digital Preservation: A View from the UK (Part 12)

Year: 2004

description: The Digital Curation Centre (DCC; www.dcc.ac.uk) has been established and funded by the UK government to provide leadership to the academic community on the related problems of scientific data curation and the long-term digital preservation of scholarly output. The funders awarded the bid to a consortium of four UK institutions, led by the University of Edinburgh, to provide a range of services for the initial three years of the centre's funding. The other partners are the University of Glasgow's Humanities Advanced Technology and Information Institute, the Council for the Central Laboratory of the Research Councils at Rutherford and Daresbury Appleton Laboratories, and the UK Office for Library and Information Networking at Bath. Each site will contribute a different expertise to the Centre, which is currently in the set-up phase of its operation. This paper will describe how a widely distributed partnership is being managed to achieve several 'proper tensions:' between the needs of the hard sciences, which represent one end of the continuum, and the needs of the soft disciplines of the social sciences and humanities along the other end; between the need for cutting edge research which will improve the state of knowledge about preservation and database curation, and the need for quick development of tools tuned to the immediate needs of the users; and among a vast array of international standards efforts and preservation tools developed under hugely disparate circumstances, all of which will be in competition for certification or publicity by the Centre, to be rubber-stamped (or not) as deserving adoption by communities of practice. Peter Burnhill, Director (Phase One) of the DCC during the set-up phase, will outline some of the drivers behind the decision to set-up the Centre, the strategy being adopted to engage such a diverse range of communities, and the approach being taken to make an organisation from four partner institutions, drawing upon experience gained in setting up the EDINA National Data Centre nine years ago. Robin Rice, Phase One Project Coordinator, will describe what the social sciences have both to offer and to learn from the other disciplines in the emerging fields of data curation and digital preservation, with a focus on the current state of the art and the challenges ahead.

description: Spin-dependent transport at heavy metal/magnetic insulator interfaces is at the origin of many phenomena at the forefront of spintronics research. A proper quantification of the different interfacial spin conductances is crucial for many applications. Here, we report the first measurement of the spin Hall magnetoresistance (SMR) of Pt on a purely ferromagnetic insulator (EuS). We perform SMR measurements in a wide range of temperatures and fit the results by using a microscopic model. From this fitting procedure we obtain the temperature dependence of the spin conductances ($G_s$, $G_r$ and $G_i$), disentangling the contribution of field-like torque ($G_i$), damping-like torque ($G_r$), and spin-flip scattering ($G_s$). An interfacial exchange field of the order of 1 meV acting upon the conduction electrons of Pt can be estimated from $G_i$, which is at least three times larger than $G_r$ below the Curie temperature. Our work provides an easy method to quantify this interfacial spin-splitting field, which play a key role in emerging fields such as superconducting spintronics and caloritronics, and topological quantum computation.

description: We present a generic model for DNA at the base-pair level. We use a variant of the Gay-Berne potential to represent the stacking energy between neighboring base-pairs. The sugar-phosphate backbones are taken into account by semi-rigid harmonic springs with a non-zero spring length. The competition of these two interactions and the introduction of a simple geometrical constraint leads to a stacked right-handed B-DNA-like conformation. The mapping of the presented model to the Marko-Siggia and the Stack-of-Plates model enables us to optimize the free model parameters so as to reproduce the experimentally known observables such as persistence lengths, mean and mean squared base-pair step parameters. For the optimized model parameters we measured the critical force where the transition from B- to S-DNA occurs to be approximately $140{pN}$. We observe an overstretched S-DNA conformation with highly inclined bases that partially preserves the stacking of successive base-pairs.

description: We study the thermodynamics of the electroweak theory at a finite lepton number density. The phase diagram of the theory is calculated by relating the full 4-dimensional theory to a 3-dimensional effective theory which has been previously solved using nonperturbative methods. It is seen that the critical temperature increases and the value of the Higgs boson mass at which the first order phase transition line ends decreases with increasing leptonic chemical potential.

description: Available interventions for preventing and treating perinatal depression remain unsatisfactory. We examined the prophylactic and therapeutic effects, as well as adverse effects, of n-3 PUFA supplementation in reducing depressive symptoms during perinatal periods. We included randomized, placebo-controlled trials that reported the changes of depression severity after the perinatal participants received n-3 PUFA supplementation. After the comprehensive searches in October 2019, we selected the trials, extracted the data, and assessed the quality of included trials. We compared the standardized mean differences (SMD) of depression score changes between groups using a random-effect model. We included 11 trials in the meta-analysis and one more trial for qualitative analysis (N = 3,181). The pooled standardized mean of decreased depression scores revealed no statistically significant difference between the n-3 PUFA and the placebo groups (N = 920, SMDs = −0.05, 95% CI −0.20 to 0.10, I2 = 21%). The pooled SMDs showed no statistically significant efficacy of n-3 PUFA supplementation for prevention (N = 779, SMDs = −0.03, 95% CI −0.20 to 0.13, I2 = 24%) and treatment (N = 141, SMDs = −0.14, 95% CI −0.55 to 0.27, I2 = 31%) of perinatal depression. The efficacy of n-3 PUFA supplementation was not associated with the daily doses of DHA, EPA, or DHA plus EPA. No trial reported any serious adverse effect of n-3 PUFA supplements. Although n-3 PUFA supplementation may improve maternal and infant outcomes, our meta-analysis found insufficient evidence to determine its benefit for perinatal depression.

description: Streptococcus pyogenes (group A streptococcus [GAS]) is a serious human pathogen with the ability to colonize mucosal surfaces such as the nasophar-ynx and vaginal tract, often leading to infections such as pharyngitis and vulvovaginitis. We present genome-wide transcriptome sequencing (RNASeq) data showing the transcriptomic changes GAS undergoes during vaginal colonization. These data reveal that the regulon controlled by MtsR, a master metal regulator, is activated during vaginal colonization. This regulon includes two genes highly expressed during vaginal colonization, hupYZ. Here we show that HupY binds heme in vitro, affects intracellular concentrations of iron, and is essential for proper growth of GAS using hemoglobin or serum as the sole iron source. HupY is also important for murine vaginal colonization of both GAS and the related vaginal colonizer and pathogen Streptococcus agalactiae (group B streptococcus [GBS]). These data provide essential information on the link between metal regulation and mucosal colonization in both GAS and GBS. IMPORTANCE Colonization of the host requires the ability to adapt to an environment that is often low in essential nutrients such as iron. Here we present data showing that the transcriptome of the important human pathogen Streptococcus pyogenes shows extensive remodeling during in vivo growth, resulting in, among many other differentially expressed genes and pathways, a significant increase in genes involved in acquiring iron from host heme. Data show that HupY, previously characterized as an adhesin in both S. pyogenes and the related pathogen Streptococcus agalactiae, binds heme and affects intracellular iron concentrations. HupY, a protein with no known heme binding domains, represents a novel heme binding protein playing an important role in bacterial iron homeostasis as well as vaginal colonization.

description: Our analysis of financial data, in terms of super-exponential growth, suggests that the seed of the 2002/03 crisis of the Dutch supermarket giant AHOLD was planted in 1996. It became quite visible in 1999 when the post-bubble destabilization regime was well-developed and acted as the precursor of an inevitable collapse fueled by raising expectations of investors to maintain strong herding pressures. We have adapted Weidlich's theory of opinion formation to describe the formation of buy or sell decisions among investors, based on a competition between the mechanisms of herding and of personal opinion opposing the herd. Among four typical patterns of stock price evolution, we have identified a ``critical zone'' in the model characterized by a strong sensitivity of the price trajectory on the herding and personal inclination parameters. The critical zone describes the maturation of a systemic instability forewarning of an inevitable crash. Classification and recognition of the spontaneous emergence of patterns of stock market evolution based on Weidlich's theory of complex systems, and in particular our discovery of the post-bubble destabilization regime which acts as a precursor to a subsequent crash or antibubble, not only presents the possibility of developing early warning signals but also suggests to top management ways of dealing with the coming crisis.

description: We study a fragment of a large quiescent filament observed on May 29, 2017 by the Interferometric BIdimensional Spectropolarimeter (IBIS) mounted at the Dunn Solar Telescope. We focus on its quiescent stage prior to its eruption. We analyse the spectral observations obtained in the H$α$ line to derive the thermodynamic properties of the plasma of the observed fragment of the filament. We used a 2D filament model employing radiative transfer computations under conditions that depart from the local thermodynamic equilibrium. We employed a forward modelling technique in which we used the 2D model to producesynthetic H_alpha line profiles that we compared with the observations. We then found the set of model input parameters, which produces synthetic spectra with the best agreement with observations. Our analysis shows that one part of the observed fragment of the filament is cooler, denser, and more dynamic than its other part that is hotter, less dense, and more quiescent. The derived temperatures in the first part range from 6,000 K to 10,000$ K and in the latter part from 11,000 K to 14,000 K. The gas pressure is 0.2-0.4 dyn/cm}^{2} in the first part and around 0.15 dyn/cm}^{2} in the latter part. The more dynamic nature of the first part is characterised by the line-of-sight velocities with absolute values of 6-7 km/s and microturbulent velocities of 8-9 km/s. On the other hand, the latter part exhibits line-of-sight velocities with absolute values 0-2.5 km/s and microturbulent velocities of 4-6 km/s.

description: Cavitating flow over a circular cylinder is investigated over a range of cavitation numbers for both laminar and turbulent regimes. We observe non-cavitating, cyclic and transitional cavitation regimes with reduction in freestream $σ$. The cavitation inside the Karman vortices in the cyclic regime, is significantly altered by the onset of "condensation front" propagation in the transitional regime. At the transition, an order of magnitude jump in shedding Strouhal number is observed as the dominant frequency shifts from periodic vortex shedding in the cyclic regime, to irregular-regular vortex shedding in the transitional regime. In addition, a peak in pressure fluctuations, and a maximum in St versus $σ$ based on cavity length are observed at the transition. Shedding characteristics in each regime are discussed using dynamic mode decomposition. It is demonstrated that the condensation fronts observed in the transitional regime are supersonic (referred as "condensation shocks"). In the presence of NCG, multiple condensation shocks in a given cycle are required for complete cavity condensation and detachment, as compared to a single condensation shock when only vapor is present. This is explained by the reduction in pressure ratio across the shock in the presence of NCG effectively reducing its strength. In addition, at $σ=0.85$ (near transition from the cyclic to the transitional regime), presence of NCG suppresses the low frequency irregular-regular vortex shedding. Vorticity transport at $Re=3900$, in the transitional regime, indicates that the region of attached cavity is nearly two-dimensional with very low vorticity, affecting Karman shedding in the near wake. In addition, the boundary-layer separation point is found to be strongly dependent on the amounts of vapor and gas in the freestream for both laminar and turbulent regimes.

description: We report on the morphological luminosity functions (LFs) and radial profiles derived for the galaxy population within the rich cluster Abell 868 (z=0.153) based purely on Hubble Space Telescope Imaging in F606W. We recover Schechter functions for early(E/S0)-, mid(Sabc)- and late(Sd/Irr)- type galaxies. The early-, mid- and late- types are all consistent with the recent field morphological LFs based on recent analysis of the Sloan Digital Sky Survey -- Early Data Release (SDSS-EDR; Nakamura et al 2003). From a detailed error analysis, including clustering of the background population, we note that improved statistics can only come from combining data from many clusters. We also examine the luminosity-density and number-density profiles as a function of morphology and draw the following conclusions: (1) The galaxies responsible for the steep faint-end slope are predominantly of late-type morphology, (2) The cluster core is dominated by elliptical galaxies, (3) The core is devoid of late-types systems, (4) The luminosity-density as a function of morphological type is skewed towards early-types when compared to the field, (5) Up to half of the elliptical galaxies may have formed from the spiral population through core disk-destruction process(es). We believe the most plausible explanation is the conventional one that late-types are destroyed during transit through the cluster core and that mid-types are converted into early-types through a similar process, which destroys the outer disk and results in a more tightly bound population of core ellipticals.[Abridged].

description: A study of morphology, kinematics and ionization structure of the IR merger NGC 5514, is presented. This study is based mainly on Integral 2D spectroscopy obtained on 4.2 m William Herschel Telescope (La Palma, Spain) and data from CASLEO (Argentina). Clear evidence of two extra-nuclear starbursts with young outflows and LINER activity are reported. One of these outflow generate a supergiant bubble, where the emission lines and kinematics maps show 4 extended ejections. These results suggest that the bubble is in the rupture phase.

Rho meson properties from combining QCD-based models

description: Aiming at the calculation of the properties of rho-mesons, non-perturbative QCD-based methods are discussed concerning their potentials as well as their short-comings. The latter are overcome by combining these techniques. The utilized methods are (i) the chiral constituent quark model deduced from the instanton vacuum model and large-N_c arguments, (ii) chiral perturbation theory unitarized by the inverse amplitude method and (iii) QCD sum rules. Advantages of the combination of these methods are especially the absence of un-physical quark-production thresholds and parameter-free results. Already in the chiral limit and in leading order in 1/N_c one obtains a reasonable result for the mass of the rho-meson, namely m_rho = 790 \pm 30 MeV. Using the KSFR relation the universality of the rho-meson coupling is recovered. The latter is found to be g = 6.0 \pm 0.3.

description: Most nonmarket valuation procedures have emphasized estimating values in a partial equilibrium context. However, changes in the nonmarket good sector are likely to affect individual's market good consumption choices. Therefore, when there is a change in the nonmarket good sector, based on the assumption of nonseparability between market and nonmarket goods, the changes in the competitive equilibrium state with respect to market goods are examined. Analysis of policy impacts indicates that competitive equilibria change depending upon the nature of substitution and complementary relationships between market and nonmarket goods, and the degree of those relationships.

description: Linux kernel stable versions serve the needs of users who value stability of the kernel over new features. The quality of such stable versions depends on the initiative of kernel developers and maintainers to propagate bug fixing patches to the stable versions. Thus, it is desirable to consider to what extent this process can be automated. A previous approach relies on words from commit messages and a small set of manually constructed code features. This approach, however, shows only moderate accuracy. In this paper, we investigate whether deep learning can provide a more accurate solution. We propose PatchNet, a hierarchical deep learning-based approach capable of automatically extracting features from commit messages and commit code and using them to identify stable patches. PatchNet contains a deep hierarchical structure that mirrors the hierarchical and sequential structure of commit code, making it distinctive from the existing deep learning models on source code. Experiments on 82,403 recent Linux patches confirm the superiority of PatchNet against various state-of-the-art baselines, including the one recently-adopted by Linux kernel maintainers.

description: Speech impairment is common in patients affected by head and neck cancer and impact on quality of life. Therefore, specific instruments are required for its evaluation. The aim of this study is to evaluate the psychometric properties of the Italian Speech Handicap Index. Data were obtained from 50 patients and 75 asymptomatic subjects. The study consisted of five phases: (1) item generation, (2) internal consistency and reliability analysis, (3) normative data generation, (4) validity analysis, performed by comparing the Italian Speech Handicap Index scores obtained in patients and asymptomatic subjects, and by correlating its scores with the results of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module, and (5) cut-off value. Internal consistency was good (Cronbach α = 0.9) and the test–retest reliability was strong. A significant difference in Italian Speech Handicap Index total score between patients and asymptomatic subjects was found. Moderate correlations between the two questionnaires were observed. A cut-off value of 14.5 demonstrated a sensitivity of 96% and a specificity of 100%. The Italian Speech Handicap Index is a reliable and valid clinical tool. Its application in everyday practice and outcome research is recommended.IMPLICATIONS FOR REHABILITATIONRehabilitation of speech in head and neck cancer patients is frequently needed, especially after surgical treatment.Speech impairment represents one of the most essential factors influencing the quality of life in head and neck cancer patients.The evaluation of the speech impairment should be performed using dedicated assessment tools.

description: Black hole feedback plays a central role in shaping the circumgalactic medium (CGM) of elliptical galaxies. We systematically study the impact of plasma physics on the evolution of ellipticals by performing three-dimensional non-ideal magneto-hydrodynamic simulations of the interactions of active galactic nucleus (AGN) jets with the CGM including magnetic fields, and cosmic rays (CRs) and their transport processes. We find that the physics of feedback operating on large galactic scales depends very sensitively on plasma physics operating on small scales. Specifically, we demonstrate that: (i) in the purely hydrodynamical case, the AGN jets initially maintain the atmospheres in global thermal balance. However, local thermal instability generically leads to the formation of massive cold disks in the vicinity of the central black hole in disagreement with observations; (ii) including weak magnetic fields prevents the formation of the disks because local B-field amplification in the precipitating cold gas leads to strong magnetic breaking, which quickly extracts angular momentum from the accreting clouds. The magnetic fields transform the cold clouds into narrow filaments that do not fall ballistically; (iii) when plasma composition in the AGN jets is dominated by CRs, and CR transport is neglected, the atmospheres exhibit cooling catastrophes due to inefficient heat transfer from the AGN to CGM despite Coulomb/hadronic CR losses being present; (iv) including CR streaming and heating restores agreement with the observations, i.e., cooling catastrophes are prevented and massive cold central disks do not form. The AGN power is reduced as its energy is utilized efficiently.

title: Chromite Deposits And Their Ultramafic Host Rocks In The Oman Ophiolite
Creators: name: Brown, Michael Anthony
Publisher: name: The Open University
Year: 1984

description: Chromite deposits in the Oman ophiolite are invariably associated with dunite bodies occurring dominantly within the upper part of the basal harzburgite unit of the ophiolite, the "Mantle Sequence". The host harzburgite and the dunite/chromitite suite show textural and geochemical evidence of origin by different genetic processes.

 Harzburgite has tectonite textures from polyphase deformation and is homogeneous on a gross scale in its mineralogy and chemistry. Harzburgite mineral compositions suggest an origin as a refractory residue from one or more partial melting episodes, low fo2 conditions, and show no systematic spatial variation. Large variations in accessory chromite are attributable to re-equilibration with variable bulk-rock alumina contents.

 Dunite-chromitite bodies are less deformed than the harzburgite and contain primary igneous textures. Chromitite spinel compositions are least affected by silicate-chromite re-equilibration and show systematic variation with depth throughout the Mantle Sequence compatible with crystallization from a rising hydrous magma diapir. Pulses of chromite precipitation may have been initiated on periodic release of magma from the diapir into the overlying chamber. Coupled with crystal settling and/or boundary layer crystallization this a possible mechanism for formation of massive chromite bodies and explains the congregation of large chromite deposits within a narrow depth zone at the top of the Mantle Sequence.

 The presence of alkali-rich minerals and volatile phases in interstices and/or primary inclusions in massive chromite deposits are significant. Clearly alkalies and volatiles are intimately associated with the processes of transport and concentration of chromium, possibly involving immiscible liquids, but little is known of the phase relations of such complex systems at present.

 Oman chromitites are not commercially very attractive for large scale investment but could be worked on a small scale and represent a further diversity in a world market dominated by two countries.
