description: U(1) gauge fields are decomposed into a monopole and photon part across the phase transition from the confinement to the Coulomb phase. We analyze the leading Lyapunov exponents of such gauge field configurations on the lattice which are initialized by quantum Monte Carlo simulations. We observe that the monopole field carries the same Lyapunov exponent as the original U(1) field. Evidence is found that monopole fields stay chaotic in the continuum whereas the photon fields are regular. First results are presented for the full spectrum of Lyapunov exponents of the U(1) gauge system.

description: In two dimensional conformal field theory the generating functional for correlators of the stress-energy tensor is given by the non-local Polyakov action associated with the background geometry. We study this functional holographically by calculating the regularized on-shell action of asymptotically AdS gravity in three dimensions, associated with a specified (but arbitrary) boundary metric. This procedure is simplified by making use of the Chern-Simons formulation, and a corresponding first-order expansion of the bulk dreibein, rather than the metric expansion of Fefferman and Graham. The dependence of the resulting functional on local moduli of the boundary metric agrees precisely with the Polyakov action, in accord with the AdS/CFT correspondence. We also verify the consistency of this result with regard to the nontrivial transformation properties of bulk solutions under Brown-Henneaux diffeomorphisms.

description: We present results from our on-going MusE GAs FLOw and Wind (MEGAFLOW) survey, which consists of 22 quasar lines-of-sight, each observed with the integral field unit (IFU) MUSE and the UVES spectrograph at the ESO Very Large Telescopes (VLT). The goals of this survey are to study the properties of the circum-galactic medium around $z\sim1$ star-forming galaxies. The absorption-line selected survey consists of 79 strong \MgII\ absorbers (with rest-frame equivalent width (REW)$\gtrsim$0.3Å) and, currently, 86 associated galaxies within 100 projected~kpc of the quasar with stellar masses ($M_\star$) from $10^9$ to $10^{11}$ \msun. We find that the cool halo gas traced by \MgII\ is not isotropically distributed around these galaxies, as we show the strong bi-modal distribution in the azimuthal angle of the apparent location of the quasar with respect to the galaxy major-axis. This supports a scenario in which outflows are bi-conical in nature and co-exist with a coplanar gaseous structure extending at least up to 60 to 80 kpc. Assuming that absorbers near the minor axis probe outflows, the current MEGAFLOW sample allowed us to select 26 galaxy-quasar pairs suitable for studying winds. From this sample, using a simple geometrical model, we find that the outflow velocity only exceeds the escape velocity when $M_{\star}\lesssim 4\times10^9$~\msun, implying the cool material is likely to fall back except in the smallest halos. Finally, we find that the mass loading factor $η$, the ratio between the ejected mass rate and the star formation rate (SFR), appears to be roughly constant with respect to the galaxy mass.

description: One of the central interests of animal movement ecology is relating movement characteristics to behavioural characteristics. The traditional discrete-time statistical tool for inferring unobserved behaviours from movement data is the hidden Markov model (HMM). While the HMM is an important and powerful tool, sometimes it is not flexible enough to appropriately fit the data. Data for marine animals often exhibit conditional autocorrelation, self-dependence of the step length process which cannot be explained solely by the behavioural state, which violates one of the main assumptions of the HMM. Using a grey seal track as an example, along with multiple simulation scenarios, we motivate and develop the conditionally autoregressive hidden Markov model (CarHMM), which is a generalization of the HMM designed specifically to handle conditional autocorrelation. In addition to introducing and examining the new CarHMM, we provide guidelines for all stages of an analysis using either an HMM or CarHMM. These include guidelines for pre-processing location data to obtain deflection angles and step lengths, model selection, and model checking. In addition to these practical guidelines, we link estimated model parameters to biologically meaningful quantities such as activity budget and residency time. We also provide interpretations of traditional "foraging" and "transiting" behaviours in the context of the new CarHMM parameters.

description: Future cosmological galaxy surveys such as the Large Synoptic Survey Telescope (LSST) will photometrically observe very large numbers of galaxies. Without spectroscopy, the redshifts required for the analysis of these data will need to be inferred using photometric redshift techniques that are scalable to large sample sizes. The high number density of sources will also mean that around half are blended. We present a Bayesian photometric redshift method for blended sources that uses Gaussian mixture models to learn the joint flux-redshift distribution from a set of unblended training galaxies, and Bayesian model comparison to infer the number of galaxies comprising a blended source. The use of Gaussian mixture models renders both of these applications computationally efficient and therefore suitable for upcoming galaxy surveys.

title: Managing Public Private Partnership (PPP) Infrastructure Projects in Jordan

description: Public Private Partnerships (PPPs) are increasingly being utilised internationally as new avenues for providing goods and services to the public with over 1,100 projects worth US$ 450 billion built around the globe between 1985 and 2008 (Siemiatycki, 2010). However, managing PPPs, particularly in the implementation phase, is both theoretically and practically complex with success largely determined by how well partnerships are managed (Grossman, 2010). Yet, PPP scholars (e.g. Bach & Whitehill, 2008; Jones & Noble, 2008) have noted that little is known about managing PPP arrangements and have called for further research to understand the ‘black box’ of PPPs (Weihe, 2008). The current research is significant in elucidating this ‘black box’ and in analysing management challenges that partnerships experience in the implementation phase. Inter-organisational relationships (IORs) and inter-organisational culture (IOC) have been identified as closely related to the PPP research and are utilised within this research to provide important insights into understanding the management of PPPs in the implementation phase. This research examines PPPs in the Jordanian context; one of the newer but most common users of PPPs in the Middle Eastern region, where PPPs are of economic strategic importance and entail significant investment risk (El-Khatib, 2008). Specifically, the current research explores ‘How effectively managed is the implementation of PPP infrastructure projects in Jordan?’ This question is explored through perceptions of PPP managers within two Jordanian case study organisations. The intention is to critically analyse how PPPs should be managed in order to contribute to the development of what might be regarded as universal theory of PPPs that can be tested, applied and generalised to other contexts. To achieve the objectives of this research, an exploratory, ontologically-oriented, qualitative research design was utilised. Data were collected from 21 in-depth, semi-structured interviews with selected informants at the senior managerial level representing different partnering organisations. Content thematic analysis was used to analyse interview data and documentary data.

description: Efficiency in the heat sector and the built environment can be achieved by building retrofits, the replacement of buildings, and the development of district heating as a means of structural energy efficiency. Hereby, excess heat and low-grade renewable heat sources can be integrated in the heat sector. The present report describes the future heat sector of Europe from end-use via infrastructure to heat sources. Future heat demands on national level have been modelled by sEEnergies project partners. In the present work, these demands are being distributed to future urban areas. Population forecasts have been combined with local empirical data to new 100m resolution population grids. They form the basis for the calculation of heat demands for the years 2030 and 2050 on the same geographical level. Potential areas, where district heating could be developed, have been zoned as prospective supply districts (PSDs) and basic statistics of heat demand have been calculated. Then, based on empirical district heating network data from existing district heating networks in Denmark, a new investment cost model for distribution and service pipes has been developed. Based on previous work in the Heat Roadmap Europe research project, the cost model has been improved with a better understanding of the concept of effective width. With the integration of country-specific construction cost data this results in an improved district heat distribution capital cost model for all Member States of the European Union plus the United Kingdom. The spatially explicit combination of district heat potentials and costs results in cost-supply curves for all countries as the basis for the assessment of the economic potential of future district heating. Finally, available excess heat sources from industry, waste incineration, wastewater treatment plants, and current powerplant locations are being allocated to prospective supply districts. Renewable heat potentials, including deep geothermal heat, solar thermal heat, and residual, local biomass, have also been assigned to these prospective heat supply areas. The results of the present work have been published as a web map.

description: Online Learning to Rank (OL2R) algorithms learn from implicit user feedback on the fly. The key of such algorithms is an unbiased estimation of gradients, which is often (trivially) achieved by uniformly sampling from the entire parameter space. This unfortunately introduces high-variance in gradient estimation, and leads to a worse regret of model estimation, especially when the dimension of parameter space is large. In this paper, we aim at reducing the variance of gradient estimation in OL2R algorithms. We project the selected updating direction into a space spanned by the feature vectors from examined documents under the current query (termed the "document space" for short), after interleaved test. Our key insight is that the result of interleaved test solely is governed by a user's relevance evaluation over the examined documents. Hence, the true gradient introduced by this test result should lie in the constructed document space, and components orthogonal to the document space in the proposed gradient can be safely removed for variance reduction. We prove that the projected gradient is an unbiased estimation of the true gradient, and show that this lower-variance gradient estimation results in significant regret reduction. Our proposed method is compatible with all existing OL2R algorithms which rank documents using a linear model. Extensive experimental comparisons with several state-of-the-art OL2R algorithms have confirmed the effectiveness of our proposed method in reducing the variance of gradient estimation and improving overall performance.

description: We investigate properties of the structural physical approximation (SPA) of the partial transposition map recently introduced by Horodecki and Ekert [quant-ph/0111064]. We focus on the case of two-qubit states and show that in this case the map has the structure of a generalized quantum measurement followed by preparation of a suitable output state. We also introduce SPA for map that transforms two copies of density matrix of a single qubit onto a square of that matrix. We prove that also this map is essentially a generalized quantum measurement.

description: The nonclassical effect of photon anti-bunching is observed in the mixed field of a narrow band two-photon source and a coherent field under certain condition. A variety of different features in photon statistics are found to be the consequence of a two-photon interference effect with dependence on the relative phase of the fields. Besides the anti-bunching effect, we find another one of the features to be also nonclassical. These features emphasize the importance of quantum entanglement.

description: In the present work, we discuss the Wheeler-DeWitt quantization scheme for an n-dimensional anisotropic cosmological model with a perfect fluid in presence of a massless scalar field. We identify the time parameter using the generalization of Schutz formalism and find the wavepacket of the universe following standard Wheeler-DeWitt methodology of quantum cosmology. We also calculate the expectation values of scale factors and volume element. We show that quantized model escapes the singularity and supports bouncing universe solutions.

 Type material of S. curticollis: Lectotype female (Muséum Nationale d’Histoire Naturelle, Paris, MNHN) (here designated): ‘‘Côte / d’Ivoire [Pic’s handwritting]’’ ‘‘TYPE’’ red label, round lectotype label, ‘‘Museum Paris / Coll. M. Pic’’, ‘‘ Simplocarina curticollis / Pic, 1922’’. Remounted in a new card, with genitalia dissected and glued on it. Paralectotypes: three females (MNHN), Côte d’Ivoire, Dimbroko, Pic collection, with paralectotype labels (one of them with the genitalia dissected and glued on the card).
 Four specimens of S. curticollis were found in the Pic collection. The first specimen of the series was labeled with Pic’s handwriting as from Côte d’Ivoire, without any further detail. The following three were labeled ‘‘ Dimbroko, Côte d’Ivoire’ ’. As in the original description (Pic, M. 1922. Nouveautés diverses. Mélanges Exotico­Entomologiques 36:1–32) no details on the number of specimens or their origin (other than Côte d’Ivoire) is given, we considered the first specimen as the lectotype and the other three as paralectotypes.
 The holotype male and nine paratypes of C. punctulatus from Parc national de la Garamba (Democratic Republic of Congo), deposited in the Musee Royal de L’Afrique Centrale (MRAC), were studied (see Delève 1968 for details on these specimens, and for a comprehensive description of the genus and species). Additional studied material of the same species included seven specimens from the NHM (Zimbabwe, former Mashonaland, Salisbury, G. A. K. Marshall leg.).
 Although the specimens of S. curticollis from Côte d’Ivoire were all females, they were morphologically identical to some of the type specimens of C. punctulatus and the additional material from Salisbury. Variability of other specimens referred to size (between 3.0 to 3.5 mm, head excluded) and color (from brown to almost black). The structure of the aedeagus was identical in all males studied, as well as all structural external characters.
We thank Nicole Berti (MNHN) and Mark de Meyer (MRAC) for the loan of specimens for study.

description: Based on statistical thermal approaches, the transverse momentum distribution of the well-identified produced particles, $π^+$, $π^-$, $K^+$, $K^-$, $p$, $\bar{p}$, is studied. From the partition function of grand-canonical ensemble, we propose a generic expression for the dependence of the full chemical potential $μ$ on rapidity $y$. Then, by fitting this expression with the experimental results of most central $p_{\perp}$ and $d^2 N/2 πp_{\bot} dp_{\bot} dy$, at $7.7$, $11.5$, $19.6$, $27$, $39$, $130$, $200~$GeV, we introduce a generic expression for the rapidity dependence of $μ$, at different energies and particle types, $μ=a+b y^2$. The resulting energy dependence reads $\sqrt{s_{\mathtt{NN}}}=c[(μ-a)/b]^{d/2}$. As a validation check, the proposed approach reproduces, excellently, the rapidity spectra measured at different energies.

description: In the paper, we study the $Υ(1S)$ leptonic decay width $Γ(Υ(1S)\to \ell^+\ell^-)$ by using the principle of maximum conformality (PMC) scale-setting approach. The PMC adopts the renormalization group equation to set the correct momentum flow of the process, whose value is independent to the choice of the renormalization scale and its prediction thus avoids the conventional renormalization scale ambiguities. Using the known next-to-next-to-next-to-leading order perturbative series together with the PMC single scale-setting approach, we do obtain a renormalization scale independent decay width, $Γ_{Υ(1S) \to e^+ e^-} = 1.262^{+0.195}_{-0.175}$ keV, where the error is squared average of those from $α_s(M_{Z})=0.1181\pm0.0011$, $m_b=4.93\pm0.03$ GeV and the choices of factorization scales within $\pm 10\%$ of their central values. To compare with the result under conventional scale-setting approach, this decay width agrees with the experimental value within errors, indicating the importance of a proper scale-setting approach.

description: This research project considers the urban environment as a valuable site to examine humanity’s relationship to nature, specifically botany, through a visual arts practice. Botany as it is used here is defined as all plant life. The project investigates a fascination with the evidence of humans’ endeavours to contain, control, and manipulate the flora in their urban habitats. The creative works and exegesis speculatively explore the potential of everyday urban encounters with botany to perceive nature as something intrinsic to both the city and ourselves, by considering flora as a tactile, vital cohabitant.Using botany as a metonym for the wider natural world, the creative works are informed by specific contemporary environmental issues, including habitat damage and encroachment, and the effects of waste associated with consumer culture. Urban botanical sites and domesticated plants have informed the drawings, sculpture, and installations that form the studio outcomes. In addition to living plants, two significant groups of materials were used in the creation of the sculptural works. The first are products associated with construction and landscaping, which signify the human intention to alter natural environments. The second are forms of consumer packaging commonly linked to environmental degradation. The creative and theoretical research asserts the vitality of these materials, revealing their potential liveliness in an ecosystem. By highlighting the entanglement of living and non-living entities that make up our urban habitats, the creative works challenge the concept of the ‘natural’ environment as being distant, wild and pure, and unsullied by the presence of humans

description: In this work, a new Monte-Carlo simulation of double parton scattering (DPS) at parton level is presented. The simulation is based on the QCD framework developed recently by M. Diehl, J. R. Gaunt and K. Schönwald. With this framework, the dynamics of the $1\to2$ perturbative splittings is consistently included inside the simulation, with the impact-parameter dependence taken into account. The simulation evolves simultaneously two hard systems from a common hard scale down to the hadronic scale. The evolution is performed using an angular-ordered parton shower which is combined with a set of double parton distributions that depend explicitly on the inter-parton distance. An illustrative study is performed in the context of same-sign WW production at the LHC, with the quark content of the proton being limited to three flavours. In several distributions we see differences compared to DPS models in Herwig, Pythia, and the DPS "pocket formula".

description: The exploitation of vehicles as mobile sensors acts as a catalyst for novel crowdsensing-based applications such as intelligent traffic control and distributed weather forecast. However, the massive increases in Machine-type Communication (MTC) highly stress the capacities of the network infrastructure. With the system-immanent limitation of resources in cellular networks and the resource competition between human cell users and MTC, more resource-efficient channel access methods are required in order to improve the coexistence of the different communicating entities. In this paper, we present a machine learning-enabled transmission scheme for client-side opportunistic data transmission. By considering the measured channel state as well as the predicted future channel behavior, delay-tolerant MTC is performed with respect to the anticipated resource-efficiency. The proposed mechanism is evaluated in comprehensive field evaluations in public Long Term Evolution (LTE) networks, where it is able to increase the mean data rate by 194% while simultaneously reducing the average power consumption by up to 54%.

description: The Milky Way, when viewed in the neutral hydrogen line emission, presents large structures called Galactic supershells (GSs). The origin of these structures is still a subject of debate. The most common scenario invoked is the combined action of strong winds from massive stars and their subsequent explosion as supernova. The aim of this work is to determine the origin of 490 GSs that belong to the Catalog of HI supershell candidates in the outer part of the Galaxy. To know the physical processes that took place to create these expanding structures, it is necessary to determine their kinetic energies. To obtain all the GS masses, we developed and used an automatic algorithm, which was tested on 95 GSs whose masses were also estimated by hand. The estimated kinetic energies of the GSs vary from $1\times10^{47}$ to $3.4\times10^{51}$ erg. Considering an efficiency of 20% for the conversion of mechanical stellar wind energy into the kinetic energy of the GSs, the estimated values of the GS energies could be reached by stellar OB associations. For the GSs located at high Galactic latitudes, the possible mechanism for their creation could be attributed to collision with high velocity clouds (HVC). We have also analysed the distribution of GSs in the Galaxy, showing that at low Galactic latitudes, $|b|<2^\circ$, most of the structures in the third Galactic quadrant seem to be projected onto the Perseus Arm. The detection of GSs at very high distances from the Galactic centre may be attributed to diffuse gas associated with the circumgalactic medium of M31 and to intra-group gas in the Local Group filament.

description: We explore applications of the maximum entropy method (MEM) to determine properties of unstable particles using the four-dimensional O(4) $ϕ^4$ theory as a laboratory. The spectral function of the correlation function of the unstable $σ$ particle is calculated with MEM, and shown to yield reliable results for both the mass of $σ$ and the energy of the two-pion state. Calculations are also made for the case in which $σ$ is stable. Distinctive differences in the volume dependence of the $σ$ mass and two-pion energy for the stable and unstable cases are analyzed in terms of perturbation theory.

Tunneling and Traversal of Ultra-cold Atoms through Vacuum Induced Potentials

Year: 2001

description: We examine the passage of ultra-cold two-level atoms through the potential produced by the vacuum of the cavity field. The peak of the transmitted wave packet generally occurs at the instant given by the expression for phase time even if that instant is earlier than the instant at which incident wave packet's peak enters the cavity and thus the phase time can be considered as the appropriate measure of the time required for the atom to traverse the cavity. We show that the phase tunneling time for ultra-cold atoms could be both super - and sub - classical time and we show how this behaviour can be understood in terms of the momentum dependence of the phase of transmission amplitude. The passage of the atom through the cavity is unique as it involves a coherent addition of the transition amplitudes corresponding to both barrier and well. New features such as the splitting of the wave packet arise from the entanglement between the center of mass motion and the electronic as well as field states in the cavity.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Impact of chiral hyperonic three-body forces on neutron stars

description: We study the effect of the nucleon-nucleon-lambda (NN$Λ$) three-body force on neutron stars. In particular, we consider the NN$Λ$ force recently derived by the Jülich--Bonn--Munich group within the framework of chiral effective field theory at next-to-next-to-leading order. This force, together with realistic nucleon-nucleon, nucleon-nucleon-nucleon and nucleon-hyperon interactions, is used to calculate the equation of state and the structure of neutron stars within the many-body non-relativistic Brueckner-Hartree-Fock approach. Our results show that the inclusion of the NN$Λ$ force leads to an equation of state stiff enough such that the resulting neutron star maximum mass is compatible with the largest currently measured ($\sim 2\ M_\odot$) neutron star masses. Using a perturbative many-body approach we calculate also the separation energy of the $Λ$ in some hypernuclei finding that the agreement with the experimental data improves for the heavier ones when the effect of the NN$Λ$ force is taken into account.

description: In chameleon $f(R)$-gravity, the fifth force will lead to `upturns' in galaxy rotation curves near the screening radius. The location of the upturn depends on the cosmic background value of the scalar field $f_{R0}$, as well as the mass, size and environment of the galaxy. We search for this signature of modified gravity in the SPARC sample of measured rotation curves, using an MCMC technique to derive constraints on $f_{R0}$. Assuming NFW dark matter haloes and with $f_{R0}$ freely varying for each galaxy, most galaxies prefer $f(R)$ gravity to $Λ$CDM, but there is a large spread of inferred $f_{R0}$ values, inconsistent with a single global value. Requiring instead a consistent $f_{R0}$ value for the whole sample, models with $\log_{10}|f_{R0}| > -6.1$ are excluded. On the other hand, models in the range $-7.5

description: We study the thermodynamics of an exact hairy black hole solution in Anti-deSitter (AdS) spacetime. We use the counterterm method supplemented with boundary terms for the scalar field to obtain the thermodynamic quantities and stress tensor of the dual field theory. We then extend our analysis by considering a dynamical cosmological constant and verify the isoperimetric inequality. Unlike the thermodynamics of Reissner-Nördstrom (RN) black hole in this `extended' framework, the presence of the scalar field and its self-interaction make also the criticality possible in the grand canonical ensemble. In the canonical ensemble, we prove that, in fact, there exist two critical points. Finally we comment on a different possible interpretation that is more natural in the context of string theory.

Modified Grover's algorithm for an expectation value quantum computer

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The translation of Grover's search algorithm from its standard version, designed for implementation on a single quantum system amenable to projective measurements, into one suitable for an ensemble of quantum computers, whose outputs are expectation values of observables, is described in detail. A filtering scheme, which effectively determines expectation values on a limited portion of the quantum state, is presented and used to locate a single item for searches involving more than one marked item. A truncated version of Grover's algorithm, requiring fewer steps than the translated standard version but locating marked items just as successfully, is proposed. For quantum computational devices which only return expectation values, the truncated version is superior to its standard counterpart. This indicates that it is possible to modify quantum algorithms so as to reduce the required temporal resources by using the ensemble's spatial resources.

description: The effects of chemical disorder on the transport properties of the spin-filter material CrVTiAl are investigated experimentally and theoretically. Synchrotron X-ray diffraction experiments on bulk CrVTiAl and the associated Rietveld analysis indicate that the crystal structure consists primarily of a mixture of a partially ordered B2 phase, a fully disordered A2 phase and a small component of an ordered L2\textsubscript{1} or Y phase. High temperature resistivity measurements confirm the existence of a band gap. First-principles, all-electron, self-consistent electronic structure computations show that the chemically disordered A2 and B2 phases are metallic, while the spin-filter properties of the ideal Y-type phase are preserved in the presence of L2\textsubscript{1} disorder. The Hall coefficient is found to decrease with increasing temperature, similar to the measured increase in the conductivity, indicating the presence of thermally activated semiconductor-like carriers.

description: In this paper we derived the precise formula in a sine function form of the norm of the amplitude in the desired state, and by means of he precise formula we presented the necessary and sufficient phase condition for any quantum algorithm with arbitrary phase rotations.
