description: The sightline toward the luminous blue hypergiant Cyg OB2-12 is widely used in studying interstellar dust on account of its large extinction ($A_V \simeq 10$ mag) and the fact that this extinction appears to be dominated by dust typical of the diffuse interstellar medium. We present a new analysis of archival ISO-SWS and Spitzer IRS observations of Cyg OB2-12 using a model of the emission from the star and its stellar wind to determine the total extinction $A_λ$ from 2.4--37 $μ$m. In addition to the prominent 9.7 and 18 $μ$m silicate features, we robustly detect absorption features associated with polycyclic aromatic hydrocarbons (PAHs), including the first identification of the 7.7 $μ$m feature in absorption. The 3.3 $μ$m aromatic feature is found to be much broader in absorption than is typically seen in emission. The 3.4 and 6.85 $μ$m aliphatic hydrocarbon features are observed with relative strengths consistent with observation of these features on sightlines toward the Galactic Center. We identify and characterize more than sixty spectral lines in this wavelength range, which may be useful in constraining models of the star and its stellar wind. Based on this analysis, we present an extinction curve $A_λ/A_{2.2 μm}$ that extrapolates smoothly to determinations of the mean Galactic extinction curve at shorter wavelengths and to dust opacities inferred from emission at longer wavelengths, providing a new constraint on models of interstellar dust in the mid-infrared.

Evidence of $σ$ particle in $J/ψ\to ωππ$
Creators: name: BES Collaboration
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Based on a sample of 7.8 million BESI $J/ψ$ events, the decay of $ J/ψ\to ωπ^+ π^-$ is studied. A low mass enhancement in the $π^+ π^-$ invariant mass spectrum recoiling against $ω$ particle is clearly seen which does not come from the phase space effect and the background. According to PWA analysis, this low mass enhancement is a broad $0^{++}$ resonance, the $σ$ particle. If a Breit-Winger function of constant width is used to fit the $σ$ signal, its mass and width are $384 \pm 66$ MeV and $458 \pm 100$ MeV respectively, which correspond to the pole position at (434 $\pm$ 78) - $i$ (202 $\pm$ 43) MeV.

description: The MUonE experiment is designed to extract the hadronic contribution to the electromagnetic coupling in the space-like region, $Δα_{\rm had}(t)$, from elastic $eμ$ scattering. The leading order hadronic vacuum polarization contribution to the muon $g-2$, $a_μ^{\mathrm{HVP, \,LO}}$, can then be obtained from a weighted integral over $Δα_{\rm had}(t)$. This, however, requires knowledge of $Δα_{\rm had}(t)$ in the whole domain of integration, which cannot be achieved by experiment. In this work, we propose to use Padé and D-Log Padé approximants as a systematic and model-independent method to fit and reliably extrapolate the future MUonE experimental data, extracting $a_μ^{\mathrm{HVP,\,LO}}$ with a conservative but competitive uncertainty, using no, or very limited, external information. The method relies on fundamental analytic properties of the two-point correlator underlying $a_μ^{\mathrm{HVP,\,LO}}$ and provides lower and upper bounds for the result for $a_μ^{\mathrm{HVP,\,LO}}$. We demonstrate the reliability of the method using toy data sets generated from a model for $Δα_{\rm had}(t)$ reflecting the expected statistics of the MUonE experiment.

description: We present evidence that AGN do not reside in ``special'' environments, but instead show large-scale clustering determined by the properties of their host galaxies. Our study is based on an angular cross-correlation analysis applied to X-ray selected AGN in the COSMOS and UDS fields, spanning redshifts from $z\sim4.5$ to $z\sim0.5$. Consistent with previous studies, we find that AGN at all epochs are on average hosted by galaxies in dark matter halos of $10^{12}-10^{13}$ M$_{\odot}$, intermediate between star-forming and passive galaxies. We find, however, that the same clustering signal can be produced by inactive (i.e. non-AGN) galaxies closely matched to the AGN in spectral class, stellar mass and redshift. We therefore argue that the inferred bias for AGN lies in between the star-forming and passive galaxy populations because AGN host galaxies are comprised of a mixture of the two populations. Although AGN hosted by higher mass galaxies are more clustered than lower mass galaxies, this stellar mass dependence disappears when passive host galaxies are removed. The strength of clustering is also largely independent of AGN X-ray luminosity. We conclude that the most important property that determines the clustering in a given AGN population is the fraction of passive host galaxies. We also infer that AGN luminosity is likely not driven by environmental triggering, and further hypothesise that AGN may be a stochastic phenomenon without a strong dependence on environment.

title: Quality aspects of vocational higher education, with special reference to hospitality management
Creators: name: Palin, Maurice George
Publisher: name: The Open University
Year: 2005

description: Quality in vocational higher education was investigated, using hospitality management as the focus. The definitions, measurement and improvement of quality (including bench marking) were explored. An analysis of the literature on quality in higher education, using books, journal articles and publications from official bodies was made and reported in Chapters 2,3 and 4. Using the literature review, structured interviews and a focus group discussion, a questionnaire related to hospitality management education was devised. It was tested by a pilot study and subsequently modified. The final questionnaire had 90 items. It was administered in Spring 2000. The questionnaire was distributed to - 315 academics, 200 employers, 71 alumni and 171 students - stakeholders in hospitality management degree courses. Respondents were asked to evaluate, using a five point Likert scale: 1) the importance of the items for quality of the courses ("ideal scale"), and 2) the extent to which the items were being achieved ("actual scale"). The results were analysed by comparing the means for each item on each scale for the four stakeholder groups. Means on the ideal scale (aspirations) were higher, item for item, than those on the actual scale (achievements). Skills, including operational skills specific to hospitality management, were considered as important components of the courses by all stakeholder groups. Factor analysis suggested that facets of quality were: employment related, operational skills, vocational preparation, generic skills, course content, computer use, influences on courses, assessment, process, and learning experiences. Based on the results, there are proposals for improving hospitality management degree courses and suggestions for further research into the complex notion of quality in higher vocational education.

description: We demonstrate that "natural inflation", also known as "axion inflation", can be compatible with Planck 2018 measurements of the cosmic microwave background, while predicting an exponentially small tensor-to-scalar ratio, e.g., $r\sim 10^{-15}$. The strong suppression of $r$ arises from dynamics of the radial component of the complex scalar field, whose phase is the axion. Such tiny values of $r$ remain well below the threshold for detection by CMB-S4 or Simons Observatory B-mode searches. The model is testable with the running $α_s$ of the spectral index, which is within reach of next-generation CMB and large-scale structure experiments, motivating the running as a primary science goal for future experiments.

description: The analysis of a simultaneous XMM-Newton/BeppoSAX plus three previous BeppoSAX observations revealed that NGC 7213 is a rather peculiar Seyfert 1. No significant Compton reflection component was observed, while an iron line complex, best explained in terms of three narrow lines, is clearly apparent in the data. Due to the absence of the reflection component, the neutral iron line is likely not produced in a Compton-thick material, but current data do not allow to choose between a Compton-thin torus and the BLR. The two ionized iron lines from \ion{Fe}{xxv} and \ion{Fe}{xxvi} may be produced in a photoionized gas with a column density of a few 10$^{23}$ cm$^{-2}$, in analogy with the case of NGC 5506.

description: The pion form factors of the QCD energy-momentum tensor (EMT) are studied in the instanton liquid model (ILM) of the QCD vacuum. In this approach the breaking of conformal symmetry is encoded in the form of stronger-than-Poisson fluctuations in the number of instantons. For the trace of the EMT, it is shown that the gluonic trace anomaly term contributes half the pion mass, with the other half coming from the quark-mass-dependent sigma term. The $Q^2$ dependence of the form factors is governed by glueball and scalar meson exchanges. For the traceless EMT, the spin-0 and 2 form factors are computed at next-to-leading order in the instanton density using effective quark operators. Relations between the gluon and quark contributions to the EMT form factors are derived. The form factors are also expressed in terms of the pion light-front wave functions in the ILM. The results at the low resolution scale of the inverse instanton size are evolved to higher scales using the renormalization group equation. The ILM results compare well with those of recent lattice QCD calculations.

Critical current density, scaling of the pinning force within the Kramer model and the irreversibility field data are presented.

We show that the singularity of the ZVW spacetime, which is represented by a segment rho=0, -sigma1. These singularities are always naked and have positive Komar masses for delta>0. Thus, they provide a non-trivial example of naked singularities with positive mass. We further show that the ZVW spacetime has a degenerate Killing horizon with a ring singularity at the equatorial plane for delta=2,3 and delta>=4. We also show that the delta=2 Tomimatsu-Sato spacetime has a degenerate horizon with two components, in contrast to the general belief that the Tomimatsu-Sato solutions with even delta do not have horizons.

We derive an effective single-band Hubbard model to describe the dynamics of the dark state polaritons under realistic assumptions. Within this model, we analyze the driven-dissipative transport of polaritons through the system by considering a coherent drive on one side and by including the spontaneous emission of the metastable Rydberg state. Using a variational approch to solve the many-body problem, we find strong antibunching of the outgoing photons despite the losses from the Rydberg state decay.

description: Photons traveling cosmological distances through the inhomogeneous Universe experience a great variation in their in-medium induced effective mass. Using the EAGLE suite of hydrodynamical simulations, we infer the free electron distribution and thereby the effective photon mass after reionization. We use this data to study the inter-conversion of kinetically mixed photons and dark photons, which may occur at a great number of resonance redshifts, and obtain the "optical depth" against conversion along random lines-of-sight. Using COBE/FIRAS, Planck, and SPT measurements, we constrain the dark photon parameter space from the depletion of CMB photons into dark photons that causes both spectral distortions and additional anisotropies in the CMB. Finally, we also consider the conversion of sub-eV dark radiation into ordinary photons. We make the line-of-sight distributions of both, free electrons and dark matter, publicly available.

subject: Intra-rural migration

description: Migration between rural locations is prevalent in developing countries and has been found to improve economic well-being in Sub-Saharan Africa. This article explores the pathways through which intra-rural migration affects well-being in rural Tanzania. Specifically, we investigate whether such migration enables migrants to access more land, higher quality land, or greater off-farm income generating opportunities that may, in turn, translate into improved well-being. Drawing on a longitudinal data set that tracks migrants to their destinations, we employ a difference-in-differences approach, validated with a multinomial treatment effects model, and find that migration confers a benefit in consumption to migrants. Results do not indicate that this advantage is derived from larger farms or, generally, from more productive farmland. However, across all destinations, migrants are more likely to draw from off-farm or nonfarm income sources, suggesting that even intra-rural migration represents a shift away from a reliance on farm production, and this is likely the dominant channel through which migrants benefit. We conclude that intra-rural migration merits greater attention in the discourse on rural development and structural transformation.
Convection with Misaligned Gravity and Rotation: Simulations and Rotating Mixing Length Theory

description: We present numerical simulations, using two complementary setups, of rotating Boussinesq thermal convection in a three-dimensional Cartesian geometry with misaligned gravity and rotation vectors. This model represents a small region at a non-polar latitude in the convection zone of a star or planet. We investigate the effects of rotation on the bulk properties of convection at different latitudes, focusing on determining the relation between the heat flux and temperature gradient. We show that our results may be interpreted using rotating mixing length theory (RMLT). The simplest version of RMLT (due to Stevenson) considers the single mode that transports the most heat. This works reasonably well in explaining our results, but there is a systematic departure from these predictions (up to approximately $30\%$ in the temperature gradient) at mid-latitudes. We develop a more detailed treatment of RMLT that includes the transport afforded by multiple modes, and we show that this accounts for most of the systematic differences. We also show that convectively-generated zonal flows and meridional circulations are produced in our simulations, and that their properties depend strongly on the dimensions of the box. These flows also affect the heat transport, contributing to departures from RMLT at some latitudes. However, we find the theoretical predictions of the multi-mode theory for the mid-layer temperature gradient, the root-mean-square (RMS) vertical velocity, the RMS temperature fluctuation, and the spatial spectrum of the heat transport at different latitudes, are all in reasonably good agreement with our numerical results when zonal flows are small.

description: We study the indication of large different branching ratios between $B^{-}\to D^{(*)0} K^{-} {K}^{0}$ and $\bar{B}_{d}\to D^{(*)+} K^{-} {K}^{0}$ observed by Belle. Interestingly, the same situation is not found in the decays $B\to D^{(*)} K^{-} {K}^{*0}$. If there exist no intermediate resonances in the decays $B^{-}\to D^{(*)0} K^{-} {K}^{0}$, a puzzle will be arisen. We find that the color-suppressed processes $B^{-}\to D^{(*)0}a^{-}_{0}(1450)$ with $a^{-}_{0}(1450)\to K^{-} {K}^{0}$ could be one of the candidates to enhance the BRs of $B^{-}\to D^{(*)0} K^{-} {K}^{0}$. Our conjecture can be examined by the Dalitz plot technique and the analysis of angular dependence on $K^{-} {K}^{0}$ state at $B$ factories.

description: Supermassive stars have been proposed as the progenitors of the massive ($\sim 10^{9}\,\rm{M}_{\odot}$) quasars observed at $z\sim7$. Prospects for directly detecting supermassive stars with next-generation facilities depend critically on their intrinsic lifetimes, as well as their formation rates. We use the 1D stellar evolution code Kepler to explore the theoretical limiting case of zero-metallicity, non-rotating stars, formed monolithically with initial masses between $10\,\rm{kM}_{\odot}$ and $190\,\rm{kM}_{\odot}$. We find that stars born with masses between $\sim60\,\rm{kM}_{\odot}$ and $\sim150\,\rm{kM}_{\odot}$ collapse at the end of the main sequence, burning stably for $\sim1.5\,\rm{Myr}$. More massive stars collapse directly through the general relativistic instability after only a thermal timescale of $\sim3\,\rm{kyr}$--$4\,\rm{kyr}$. The expected difficulty in producing such massive, thermally-relaxed objects, together with recent results for currently preferred rapidly-accreting formation models, suggests that such ``truly direct'' or ``dark'' collapses may not be typical for supermassive objects in the early Universe. We close by discussing the evolution of supermassive stars in the broader context of massive primordial stellar evolution and the possibility of supermassive stellar explosions.

description: Although studies of the determinants of farmland prices are common in developed country settings, such analyses are extremely scarce in Sub-Saharan Africa. This paper offers a comprehensive examination of land values across Tanzania. Land prices rose significantly between 2008/09 and 2012/13, presenting a potential obstacle to land access for poor and aspiring farmers. A hedonic analysis reveals that indicators of agricultural potential, local population density, and access to markets/urban centers are all statistically significant determinants of land values in Tanzania. The paper concludes with a discussion of promising directions for future research on land values in SubSaharan Africa.

Noncritical M-theory and the Gross-Neveu model in 2+1 dimensions

description: We point out a non-trivial connection between the model proposed by Horava and Keeler as a candidate for noncritical M-theory and the Gross-Neveu model with fermionic fields obeying periodic boundary conditions in 2+1 dimensions. Specifically, the vacuum energy of the former is identified with the large-N free-energy of the latter up to an overall constant. This identification involves an appropriate analytic continuation of the subtraction point in noncritical M-theory, which is related to the volume of the Liouville dimension. We show how the world-sheet cosmological constant may be obtained from the Gross-Neveu model. At its critical point, which is given in terms of the golden mean, the values of the vacuum energy and of the cosmological constant are 4/5 and 2/5 of the corresponding values at infinite string coupling constant.

Uncertainty Relations for Noise and Disturbance in Generalized Quantum Measurements
Creators: name: Ozawa, Masanao
Publisher: name: arXiv
Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Heisenberg's uncertainty relation for measurement noise and disturbance states that any position measurement with noise epsilon brings the momentum disturbance not less than hbar/2epsilon. This relation holds only for restricted class of measuring apparatuses. Here, Heisenberg's uncertainty relation is generalized to a relation that holds for all the possible quantum measurements, from which conditions are obtained for measuring apparatuses to satisfy Heisenberg's relation. In particular, every apparatus with the noise and the disturbance statistically independent from the measured object is proven to satisfy Heisenberg's relation. For this purpose, all the possible quantum measurements are characterized by naturally acceptable axioms. Then, a mathematical notion of the distance between probability operator valued measures and observables is introduced and the basic properties are explored. Based on this notion, the measurement noise and disturbance are naturally defined for any quantum measurements in a model independent formulation. Under this formulation, various uncertainty relations are also derived for apparatuses with independent noise, independent disturbance, unbiased noise, and unbiased disturbance as well as noiseless apparatuses and nondisturbing apparatuses. Two models of position measurements are discussed to show that Heisenberg's relation can be violated even by approximately repeatable position measurements.

title: An Architecture for Multilevel Learning and Robotic Control based on Concept Generation
Creators: name: Iravani, Pejman
Publisher: name: The Open University
Year: 2005

description: Robot and multi-robot systems are inherently complex systems, for which designing the programs to control their behaviours proves complicated. Moreover, control programs that have been successfully designed for a particular environment and task can become useless if either of these change. It is for this reason that this thesis investigates the use of machine learning within robot and multi-robot systems. It explores an architecture for machine learning, applied to autonomous mobile robots based on dividing the learning task into two individual but interleaved sub-tasks. The first sub-task consists of finding an appropriate representation on which to base behaviour learning. The thesis explores the viability of using multidimensional classification techniques to generalise the original sensor and motor representations into abstract hierarchies of 'concepts'. To construct concepts the research used standard classification techniques, and experimented with a novel method of multidimensional data classification based on 'Q-analysis'. Results suggest that this may be a powerful new approach to concept learning. The second sub-task consists of using the previously acquired concepts as the representation for behaviour learning. The thesis explores whether it is possible to learn robotic behaviours represented using concepts. Results show that is possible to learn low-level behaviours such as navigation and higher-level ones such as ball passing in robot football. The thesis concludes that the proposed architecture is viable for robotic behaviour learning and control, and that incorporating Q-analysis based classification results in a promising new approach to the control of robot and multi-robot systems.

description: We revisit the hard QCD contributions to the pion gravitational form factors (GFFs), in terms of the twist-2,3 pion distribution amplitudes (DA), including novel semi-hard contributions from the instantons. The pion DAs are evaluated in the QCD instanton vacuum, and then properly evolved to higher resolution. The results are compared to our recent results from the QCD instanton vacuum, as well as Bethe-Salpeter calculations and recent lattice data. The interpolated hard and soft contributions to the pion D-form-factor, are used to derive the (gravitational) pressure and shear within the pion, with a clear delineation of their range.

WOMEN′S WELFARE AND LIVELIHOODS OUTSIDE OF MARRIAGE: EVIDENCE FROM RURAL TANZANIA

description: This paper explores the welfare and livelihood strategies of women in rural Tanzania after they exit marriage. We draw from a three-wave individual-level longitudinal survey, using a correlated random effects approach within regression analysis to control for time-invariant individual effects. Attention is given to whether women exit marriage through widowhood or divorce, and whether they subsequently become household heads or join another household. Nearly 40% of widowed or divorced women are not the heads of their households, but instead reside with relatives. We find that women, and particularly widows, are more likely to be poor after marriage exit. Upon widowhood or divorce, women also work longer hours in off-farm employment, and those who become household heads are especially likely to experience a reduction in land access and a heightened reliance on non-farm income, including the receipt of transfers. This underscores the importance of both the non-farm economy and family networks for women′s livelihoods after marriage. Results illustrate that women′s experiences outside of marriage are diverse and cannot be broadly proxied with a household status of being female-headed.
