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.

Detection of Bipolar Flow toward an Unusual SiO Maser Source IRAS 19312+1950

description: We report a result of an interferometric observation toward an SiO maser source, IRAS 19312+1950, in the HCO+ J=1-0 line with the Berkeley-Illinois-Maryland-Association (BIMA) Millimeter Array. In the spatially integrated spectrum of HCO+, two kinematic components were seen: a strong line with a narrow width (~2 km/s, narrow component), and a weak symmetric line with a broad width (~60 km/s, broad component). The line profile of HCO+ are reminiscent of that of CO. In the integrated intensity map, we found a pronounced bipolar shape consisting of lower-velocity parts of the broad component. The higher-velocity part of the broad component originated in a relatively small region (< 3"). The spatial structure of the narrow component clearly correlated with near-infrared structure. The position-velocity diagrams indicated presence of a bipolar outflow with an expansion velocity of about 10 km/s. On the basis of the present results, we suggest that the nature of the bipolar flow seen in IRAS 19312+1950 is explained by hydrodynamical interaction between an AGB wind and ambient material with axial symmetric structure.

description: Benjamini, Lyons and Schramm [Random Walks and Discrete Potential Theory (1999) 56-84] considered properties of an infinite graph G, and the simple random walk on it, that are preserved by random perturbations. In this paper we solve several problems raised by those authors. The anchored expansion constant is a variant of the Cheeger constant; its positivity implies positive lower speed for the simple random walk, as shown by Virag [Geom. Funct. Anal. 10 (2000) 1588-1605]. We prove that if G has a positive anchored expansion constant, then so does every infinite cluster of independent percolation with parameter p sufficiently close to 1; a better estimate for the parameters p where this holds is in the Appendix. We also show that positivity of the anchored expansion constant is preserved under a random stretch if and only if the stretching law has an exponential tail. We then study a simple random walk in the infinite percolation cluster in Cayley graphs of certain amenable groups known as ``lamplighter groups.'' We prove that zero speed for a random walk on a lamplighter group implies zero speed for random walk on an infinite cluster, for any supercritical percolation parameter p. For p large enough, we also establish the converse.

description: The current theoretical status of the Lamb shift in He+ is discussed. Recent calculations of two-loop binding corrections to the Lamb shift significantly shift the theoretical value of the "classic" Lamb shift in He+, i.e. of the 2S_1/2-2P_1/2-interval. In this brief research note, we present a new (theoretical) value for this interval which reads 14041.474(42) Mhz. The theoretical uncertainty is reduced as well as the discrepancy between theory and experiment. Planned measurements should be of help in further elucidating the situation.

description: Nonnegative matrix factorization (NMF) is a widely used linear dimensionality reduction technique for nonnegative data. NMF requires that each data point is approximated by a convex combination of basis elements. Archetypal analysis (AA), also referred to as convex NMF, is a well-known NMF variant imposing that the basis elements are themselves convex combinations of the data points. AA has the advantage to be more interpretable than NMF because the basis elements are directly constructed from the data points. However, it usually suffers from a high data fitting error because the basis elements are constrained to be contained in the convex cone of the data points. In this letter, we introduce near-convex archetypal analysis (NCAA) which combines the advantages of both AA and NMF. As for AA, the basis vectors are required to be linear combinations of the data points and hence are easily interpretable. As for NMF, the additional flexibility in choosing the basis elements allows NCAA to have a low data fitting error. We show that NCAA compares favorably with a state-of-the-art minimum-volume NMF method on synthetic datasets and on a real-world hyperspectral image.

sin(2 phi) current-phase relation in SFS junctions with decoherence in the ferromagnet

description: We propose a theoretical description of the sin(2 phi) current-phase relation in SFS junctions at the 0-$π$ cross-over obtained in recent experiments by Sellier et al. [Phys. Rev. Lett. 92, 257005 (2004)] where it was suggested that a strong decoherence in the magnetic alloy can explain the magnitude of the residual supercurrent at the 0-pi cross-over. To describe the interplay between decoherence and elastic scattering in the ferromagnet we use an analogy with crossed Andreev reflection in the presence of disorder. The supercurrent as a function of the length R of the ferromagnet decays exponentially over a length xi, larger than the elastic scattering length $l_d$ in the absence of decoherence, and smaller than the coherence length $l_ϕ$ in the absence of elastic scattering on impurities. The best fit leads to $ξ\simeq ξ_h^{({\rm diff})}/3$, where $ξ_h^{({\rm diff})}$ is exchange length of the diffusive system without decoherence (also equal to $ξ$ in the absence of decoherence). The fit of experiments works well for the amplitude of both the sin(phi) and sin(2 phi) harmonics.

description: La economía circular es un modelo que busca optimizar el uso de recursos naturales y gestionar residuos de manera eficiente, mediante la reducción, reutilización y reciclaje. En revisión se realiza una descripción general que sintetiza las líneas de acción priorizadas, vehículos y mecanismos que integra el documento de la Estrategia Nacional de Economía Circular en Colombia. Dentro de las líneas de acción se hace énfasis en el flujo de materiales como productos de consumo, envases, biomasa, agua, energía y construcción. Para ello se promueven vehículos que facilitan la transformación los sistemas productivos y promueven sinergias a través de mecanismos como la responsabilidad extendida del productor, nuevos modelos de negocio y parques industriales ecoeficientes. La gobernanza de este tipo de estrategias implica una estructura colaborativa con participación de diversos actores para implementar políticas adecuadas. Desde la implementación del documento de la estrategia nacional de economía circular en 2018, se han observado progresos significativos, como el aumento en la tasa de aprovechamiento de residuos sólidos, que pasó del 51.4% al 53.36%, y la creación de aproximadamente 115000 empleos verdes en el país. Estas iniciativas son fundamentales para consolidar un modelo económico más sostenible y responsable. Sin embargo, la continuidad y el fortalecimiento de estas acciones son esenciales para garantizar los beneficios a largo plazo de la economía circular en Colombia.

Quantum soliton scattering manifolds

Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider the quantum multisoliton scattering problem. For BPS theories one truncates the full field theory to the moduli space, a finite dimensional manifold of energy minimising field configurations, and studies the quantum mechanical problem on this. Non-BPS theories -- the generic case -- have no such obvious truncation. We define a quantum soliton scattering manifold as a configuration space which satisfies asymptotic completeness and respects the underlying classical dynamics of slow moving solitons. Having done this, we present a new method to construct such manifolds. In the BPS case the dimension of the $n$-soliton moduli space $\mathcal{M}_n$ is $n$ multiplied by the dimension of $\mathcal{M}_1$. We show that this scaling is not necessarily valid for scattering manifolds in non-BPS theories, and argue that it is false for the Skyrme and baby-Skyrme models. In these models, we show that a relative phase difference can generate a relative size difference during a soliton collision. Asymptotically, these are zero and non-zero modes respectively and this new mechanism softens the dichotomy between such modes. Using this discovery, we then show that all previous truncations of the 2-Skyrmion configuration space are unsuitable for the quantum scattering problem as they have the wrong dimension. This gives credence to recent numerical work which suggests that the low-energy configuration space is 14-dimensional (rather than 12-dimensional, as previously thought). We suggest some ways to construct a suitable manifold for the 2-Skyrmion problem, and discuss applications of our new definition and construction for general soliton theories.

Neutron Star Kicks from Asymmetric Collapse

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Many neutron stars are observed to be moving with spatial velocities, in excess of 500km/s. A number of mechanisms have been proposed to give neutron stars these high velocities. One of the leading classes of models proposed invokes asymmetries in the core of a massive star just prior to collapse. These asymmetries grow during the collapse, causing the resultant supernova to also be asymmetric. As the ejecta is launched, it pushes off (or ``kicks'') the newly formed neutron star. This paper presents the first 3-dimensional supernova simulations of this process. The ejecta is not the only matter that kicks the newly-formed neutron star. Neutrinos also carry away momentum and the asymmetric collapse leads also to asymmetries in the neutrinos. However, the neutrino asymmetries tend to damp out the neutron star motions and even the most extreme asymmetric collapses presented here do not produce final neutron star velocities above 200km/s.

description: By parametrizing the action integral for the standard Schrodinger equation we present a derivation of the recently proposed method for quantizing a parametrized theory. The reformulation suggests a natural extension from conventional to nonlinear quantum mechanics. This generalization enables a unitary description of the quantum evolution for a broad class of constrained Hamiltonian systems with a nonlinear kinematic structure. In particular, the new theory is applicable to the quantization of cosmological models where a chosen gravitational degree of freedom acts as geometric time. This is demonstrated explicitly using three cosmological models: the Friedmann universe with a massless scalar field and Bianchi type I and IX models. Based on these investigations, the prospect of further developing the proposed quantization scheme in the context of quantum gravity is discussed.

description: Any realistic quantum system is inevitably subject to an external environment. This environment makes the open-system dynamics significant for many quantum tech-nologies, such as entangled-state engineering, quantum simulation, and quantum sensing. The information flow of a system to its environment usually induces a Markovian process, while the backflow of information from the environment exhibits non-Markovianity. The practical environment, usually consisting of a large number of degrees of freedom, is hard to control, despite some attempts on controllable transitions from Markovian to non-Markovian dynamics. Here, we experimentally demonstrate the engineering of multiple dissipative channels by controlling the adjacent nuclear spins of a nitrogen-vacancy centre in diamond. With a controllable non-Markovian dynamics of the open system, we observe that the quantum Fisher information flows to and from the environment using different noisy channels. Our work contributes to the developments of both noisy quantum metrology and quantum open systems from the view points of metrologically useful entanglement.

description: We study the prospects of searching for black hole (BH) binary systems with a stellar-mass BH and a non-compact visible companion, by utilizing the spectroscopic data of Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). We simulate the Galactic BH binary population and determine its optical visibility by considering the stellar synthetic population model and the distributions of binary orbital parameters. By convolving the visibility of BH binaries with the LAMOST detection sensitivity, we predict that $\gtrsim$ 400 candidate BH binaries can be found by the low-resolution, non-time-domain survey, and $\sim$ 50-350 candidates by the LAMOST ongoing medium-resolution, time-domain spectroscopic survey. Most of the candidates are short-period (0.2-2 days) binaries with M-, K-, G-, or F-type companions, in which $\sim$ 47% have a mass function (the lower limit of the BH mass) larger than 3 $M_{\odot}$. By complementing the LAMOST spectroscopic data with other photometric/spectroscopic surveys or follow-up observations, these candidates could be confirmed. Therefore, by exploring the LAMOST data, we can enlarge the sample of dynamically confirmed BH binaries significantly, which can improve our understanding of the mass distribution of BHs and the stellar evolution model.

description: This study uses the propensity score matching approach to empirically analyze farmers’ preference for adaptation to climate change in rice production and the impact of adaptation response on their livelihood, more specifically on household income. Observational data were obtained from interviews with 80 Soc Trang rice farmers in the Mekong Delta, Vietnam. The findings indicate that 74% of farmers typically decided to adapt their rice farming to climate change with respect to salinity intrusion while 26% of farmers did not. The choice of adaptation response is significantly influenced by education, social norm, location at district level and micro-level (e.g. access to water sources). Furthermore, the study demonstrates that adaptation response to climate change at the farm level has a positive impact on household income. Specifically, farmers who have adapted their rice farming to salinity intrusion have a higher annual income (about 34 million Vietnamese Dong) than those who have not adapted.

description: Hydrodynamic equations for an isotropic solution of active polar filaments are derived from a microscopic mean-field model of the forces exchanged between motors and filaments. We find that a spatial dependence of the motor stepping rate along the filament is essential to drive bundle formation. A number of differences arise as compared to hydrodynamics derived (earlier) from a mesoscopic model where relative filament velocities were obtained on the basis of symmetry considerations. Due to the anisotropy of filament diffusion, motors are capable of generating net filament motion relative to the solvent. The effect of this new term on the stability of the homogeneous state is investigated.

Sensitivity of Numerical Predictions to the Permeability Coefficient in Simulations of Melting and Solidification Using the Enthalpy-Porosity Method

description: The high degree of uncertainty and conflicting literature data on the value of the permeability coefficient (also known as the mushy zone constant), which aims to dampen fluid velocities in the mushy zone and suppress them in solid regions, is a critical drawback when using the fixed-grid enthalpy-porosity technique for modelling non-isothermal phase-change processes. In the present study, the sensitivity of numerical predictions to the value of this coefficient was scrutinised. Using finite-volume based numerical simulations of isothermal and non-isothermal melting and solidification problems, the causes of increased sensitivity were identified. It was found that depending on the mushy-zone thickness and the velocity field, the solid-liquid interface morphology and the rate of phase-change are sensitive to the permeability coefficient. It is demonstrated that numerical predictions of an isothermal phase-change problem are independent of the permeability coefficient for sufficiently fine meshes. It is also shown that sensitivity to the choice of permeability coefficient can be assessed by means of an appropriately defined Péclet number.

description: The Hamiltonian of a system of three quantum mechanical particles moving on the three-dimensional lattice $\Z^3$ and interacting via zero-range attractive potentials is considered. For the two-particle energy operator $h(k),$ with $k\in \T^3=(-π,π]^3$ the two-particle quasi-momentum, the existence of a unique positive eigenvalue below the bottom of the continuous spectrum of $h(k)$ for $k\neq0$ is proven, provided that $h(0)$ has a zero energy resonance. The location of the essential and discrete spectra of the three-particle discrete Schrödinger operator $H(K), K\in \T^3$ being the three-particle quasi-momentum, is studied. The existence of infinitely many eigenvalues of H(0) is proven. It is found that for the number $N(0,z)$ of eigenvalues of H(0) lying below $z<0$ the following limit exists $$ \lim_{z\to 0-} \frac {N(0,z)}{\mid \log\mid z\mid\mid}=\cU_0 $$ with $\cU_0>0$. Moreover, for all sufficiently small nonzero values of the three-particle quasi-momentum $K$ the finiteness of the number $ N(K,τ_{ess}(K))$ of eigenvalues of $H(K)$ below the essential spectrum is established and the asymptotics for the number $N(K,0)$ of eigenvalues lying below zero is given.

description: The field of the globular cluster M10 (NGC 6254) was monitored between 1998 and 2015 in a search for variable stars. V -light curves were derived for 40 variables or likely variables, most of which are new detections. Proper motions obtained within the CASE project indicate that 18 newly detected variables and 14 previously known ones are members or likely members of the cluster, including one RRc-type, three type II Cepheids, and 14 SX Phe-type pulsators, one contact binary, and six semi-regular red giants. As a byproduct of the search we discovered a candidate binary comprised of main sequence stars with the record-short orbital period of 0.042 d. We also confirmed the photometric variability of the red straggler M10-VLA1 hinted at by Shishkovsky et al. (2018), who discovered this object spectroscopically. In Appendix 1 we show that CASE proper motion measurements are in a good agreement with those retrieved from the Gaia archive, while Appendix 2 presents evidence for low frequency γ Doradus-type oscillations in SX Phe stars belonging to M10.
title: An Investigation into the Implementation of National Curriculum Design and Technology in a State Secondary School
Creators: name: Harrison, Michael Ernest
Publisher: name: The Open University
Year: 1994

description: The thesis deals with the process of curriculum change initiated by the British government's decision to include a national curriculum requirement in its Education Reform Act of 1988. The particular focus is on the development of the subject of Design and Technology, which was the only new subject in the national curriculum, and which, in the secondary phase, was required to be taught cooperatively by teachers of several existing subjects. The thesis demonstrates the need to combine two approaches to curriculum change in order to understand the process. The first is that typified by the work of Goodson, who maintains that subjects develop through the activities of disparate interest groups. The second is that typified by the work of Fullan, who maintains that change will only be successful if those involved are enabled to construct their own meaning for the change. Combining these two approaches at school level (which is a development of the approach of Goodson, who deals mostly at national level), demonstrates the complexity of the change process, and the need for a change strategy that handles this complexity.

 In summary, the thesis is that the existence of many interest groups in the new area of design and technology in the national curriculum makes the processes of specifying the subject at national level, and implementing it at school level, difficult and controversial. For the processes of curriculum change to take place effectively, a strategy for change is required that recognizes the conditions within which teachers work, and the structures of organization and meaning that support their work. In the case of subject teachers in secondary schools, this means recognizing the influence of subject and departmental interest groups, as well as the influence of school organizational structures. Failure to apply such a strategy inhibits the change process and may result in outcomes that are less satisfactory then is desired.
Stellar Kinematics of Boxy Bulges: Large-Scale Bars and Inner Disks

description: Major-axis long-slit stellar kinematics was obtained for 30 edge-on spiral galaxies, 24 with a boxy/peanut-shaped (B/PS) bulge. B/PS bulges are present in >45% of highly inclined systems and much work suggests that they are the edge-on projection of thick bars. Profiles of the mean stellar velocity V, the velocity dispersion sigma, and the asymmetric (h3) and symmetric (h4) deviations from a Gaussian are presented. Comparing those with N-body bar diagnostics, we find bar signatures in 80% of our sample. B/PS bulge galaxies typically show a double-hump rotation curve with an intermediate dip or plateau. They often show a flat central velocity dispersion profile accompanied by a secondary peak or plateau and >=40% have a local central sigma minimum. The h3 profiles display up to 3 slope reversals and h3 is normally correlated with V over the presumed bar length, contrary to expectations from axisymmetric disks. Those characteristic bar signatures strengthen the case for a close link between B/PS bulges and bars. h3 is anti-correlated with V in the very center of most galaxies, indicating that they additionally harbor cold and dense decoupled nearly axisymmetric central stellar disks. These coincide with previously identified star-forming ionized-gas disks in the gas-rich systems, and we argue that they formed out of gas inflow driven by the bar. As suggested by N-body models, h3 appears to be a reliable tracer of asymmetries in disks, allowing to discriminate between axisymmetric and barred disks seen in projection. B/PS bulges (and thus a large fraction of all bulges) appear to be made-up mostly of disk material which has acquired a large vertical extent through bar-driven vertical instabilities. Their formation is thus probably dominated by secular evolution processes rather than merging. [Abridged]

description: Farmers in Afghanistan are able to produce quality grain, however, are unable to store the grain to maintain quality and seed viability. This greatly contributes to high rates of poverty and food insecurity. The Purdue Improved Crop Storage (PICS) bags are a means of low-cost hermetic storage that provides efficient, airtight grain storage for small size farmers that can reduce the loss of crops during storage and provide more food to people. The expected profitability of PICS bags compared to current storage used by farmers was determined before a specific distribution strategy for PICS bags in Afghanistan is implemented. Wheat samples from Balkh, Herat, and Nangarhar provinces were stored in either PICS bags or local woven polypropylene (PP) bags and sampled following 3 and 6 months of storage. The samples were examined for insect damage and percent germination following storage to determine the economic return from each type of storage system. The value of reduced storage loss with use of the PICS bags is greater than the cost of th refore, the economic return on PICS bags is higher than that of PP bags. This indicates the use of PICS bags is better than current storage practices. The PICS bag storage technology appears to be a viable option for grain storage in Afghanistan to prevent grain damage and to maintain seed quality and viability for wheat.

description: Corridors perform a substantial role to boost up agribusiness comprehensively for developing a linear agglomeration of people and pursuits pre-existing transport structure. This research explored the social and economic impact of China Pakistan Economic Corridor on agriculture productiveness. The analysis has been executed among the distinct districts of agricultural economic zones. The paper signifies accessibility and usage of infrastructure, to analyze nexus. Regardless of available facts & figures, the data restricted the variables that might be deemed the research support of higher investment in infrastructures, energy and dams whilst at the similar time stressing the need to take steps to maximize the utilization of existing resources. Indices for the development of Infrastructure have been designed by applying Principal Component Analysis. Random effects model is implemented to analyze how diverse categories of infrastructure affect agricultural productivity. CPEC projects have potential to cover the current energy crises in Pakistan and open up business horizons for the small scale farmers to raise productivity and exports.

description: The impact of final-state radiation (FSR) on the radiative return method for the extraction of the e+e- hadronic cross section is discussed in detail. Possible experimental tests of the model dependence of FSR are proposed for the pi+pi- hadronic final state. The importance of the (pi+pi-photon) final state contribution to the muon anomalous magnetic moment is investigated, and a method based on the radiative return is proposed to extract these contributions from data.

description: Self-dual string cosmological models provide an effective example of bouncing solutions where a phase of accelerated contraction smoothly evolves into an epoch of decelerated Friedmann--Robertson--Walker expansion dominated by the dilaton. While the transition to the expanding regime occurs at sub-Planckian curvature scales, the Universe emerging after the bounce is cold, with sharply growing gauge coupling. However, since massless gauge bosons (as well as other massless fields) are super-adiabatically amplified, the energy density of the maximally amplified modes re-entering the horizon after the bounce can efficiently heat the Universe. As a consequence the gauge coupling reaches a constant value, which can still be perturbative.

description: Model builders and policy analysts have relied on their subjective price-effect estimation on fish and other meat components in consumer diet with the result that their analyses do not exactly and reliably reflect the reality. This study provides empirical price-effect analysis of the demand for meat- and fish-consuming rural households in South-eastern Nigeria. Data collected from 590 rural household consumers of meat and fish were analyzed using the Linear Approximate Almost Ideal Demand System (LA/AIDS) and the Slusky decomposition. The results showed that meat and fish consumers exhibit some inconsistent behaviour in expenditure, and expend the highest proportion of their conditional income on chicken with mo relationship in commodities demand by price of fish. Fish and other meat components are necessities with only chicken as a luxury commodity in the region. Although, the unobservable own-price effect components of the total price-change show that there is likely no preference ordering that can rationalize observed meat and fish consumer demand behaviour in the region, the consumers are consistent in their choice among the different commodities. The compensated demand curve for the commodities, except for chicken is downward-sloping, while the unobservable own-price effect of fish and meat are higher than their income effect. Only the income-effect on meat and fish consumption in the region was higher than the substitution effect for chicken meat in relation to fish and other components of meat. Therefore, price-oriented policies interventions rather than income-oriented policies would be a more effective tool to combat animal protein-deficient nutrition in the basic diet of consumers in the region.
