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.

description: We present the analysis of the 1/Q-suppressed non-perturbative (NP) contribution to the cumulative out-of-event-plane momentum distribution in e+e- annihilation in the near-to-planar three-jet region. It complements our previous study of the perturbative (PT) distributions resummed to single logarithmic accuracy. Due to inter-jet soft gluon radiation, the NP contributions (as well as the PT distributions) are sensitive to the geometry (the angles between jets) and the colour structure of the underlying hard process (topology of the three-prong parton antenna). The results and techniques presented here could be extended to other multi-jet processes and, in particular, to hadron-hadron collisions.

Subjects: Applied Computer Science

description: Mobile communication is rapidly emergent articulation of the communication surroundings. Users move to the various location and access various services to accomplish their requirements in mobile environment. These location navigation and service invocation are characterized as a Mobile User Behavior Pattern (MUBP).User behavior pattern analyses mobile user’s destination point and their service utilization. Region pattern inquires the details of users target location. Access pattern specifies the services utilized by mobile users. User behavior pattern provides better quality and good services to the mobile users in time. User behavior patterns are not only helpful for user, but also for service providers.Analysis of user behavior pattern gives benefit to the users by invoking the services without traffic congestion problem and to the service providers by contributing the immediate response to mobile users. This study analyzes the behavior of user pattern in detail related to existing work of 24 authors from the past few years.
Polynomial Solutions to Pell's Equation and Fundamental Units in Real Quadratic Fields

Subjects: subject: Number Theory (math.NT)

description: Finding polynomial solutions to Pell's equation is of interest as such solutions sometimes allow the fundamental units to be determined in an infinite class of real quadratic fields. In this paper, for each triple of positive integers $(c,h,f)$ satisfying \[c^{2}-f\,h^{2}=1, \] where $(c,h)$ are the smallest pair of integers satisfying this equation, several sets of polynomials $(c(t),h(t),f(t))$ which satisfy \[c(t)^{2}-f(t)\,h(t)^{2}=1 \text{ and } (c(0),h(0),f(0)) = (c,h,f) \] are derived. Moreover, it is shown that the pair $(c(t),h(t))$ constitute the fundamental polynomial solution to the Pell's equation above. The continued fraction expansion of $\sqrt{f(t)}$ is given in certain general cases (for example, when the continued fraction expansion of $\sqrt{f}$ has odd period length, or even period length or has period length $\equiv 2 \mod{4}$ and the middle quotient has a particular form etc). Some applications to determining the fundamental unit in real quadratic fields is also discussed.

description: It is shown that a certain sum rule for soft supersymmetry-breaking scalar masses, which has been recently found in a certain class of superstring models, is universal for gauge-Yukawa unified models. To explain this coincidence, we argue that the low-energy remnant of the target-space duality invariance in the effective supergravity of compactified superstrings can be identified with the (broken) scale invariance in gauge-Yukawa unified models, and that gauge-Yukawa unification which is indispensable for the sum rule to be satisfied follows from the matching of anomalies.

description: The error threshold transition in a stochastic (i.e. finite population) version of the quasispecies model of molecular evolution is studied using finite-size scaling. For the single-sharp-peak replication landscape, the deterministic model exhibits a first-order transition at $Q=Q_c=1/a$, where $% Q$ is the probability of exact replication of a molecule of length $L \to \infty$, and $a$ is the selective advantage of the master string. For sufficiently large population size, $N$, we show that in the critical region the characteristic time for the vanishing of the master strings from the population is described very well by the scaling assumption $τ= N^{1/2} f_a \left [ \left (Q - Q_c) N^{1/2} \right ] $, where $f_a$ is an $a$-dependent scaling function.

description: Ein wichtiges Verdienst der bahnbrechenden Large-Scale-Untersuchungen TIMMS und PISA war die Entwicklung und Durchsetzung einer neuartigen Forschungsmethodik für Lernprozesse, in deren Mittelpunkt der Kompetenzbegriff (im Sinne von Weinert) und die Messung von Kompetenzen mit Hilfe der Item Response Theory rückte. Ein Nebeneffekt war allerdings dabei die Popularisierung des Begriffs „Kompetenz“, der inzwischen in der Alltagssprache zu einer vagen Bezeichnung für „etwas können“ verkommen ist. International wird die Fachgemeinde der Informatikdidaktik (DDI) vor allem von den US-Verbänden ACM und IEEE dominiert, bei denen der Kompetenzbegriff bei weitem noch nicht die Aufmerksamkeit und Bedeutung erlangt hat wie in Europa. Daher gibt es auf internationaler Ebene bisher nur sehr wenige solide Forschungsergebnisse zu empirisch fundierten Kompetenzen oder -modellen aus der Informatik, insbesondere zum Programmieren. Für unser neues DFG-Projekt AKoFOOP haben wir uns daher zusammen mit der Essener Paluno-Gruppe vorgenommen, einige ausgewählte Kompetenzen aus dem Bereich der objektorientierten Programmierung empirisch zu identifizieren, Instrumente zu deren Messung zu entwickeln und auf der Grundlage dieser Vorarbeiten das Feedback bei der automatischen Programmanalyse durch das JACK System zu verbessern. Die Ergebnisse sollen dann auch in unserem MOOC zur objektorientierten Programmierung (LOOP) genutzt werden. In diesem Vortrag will ich die Grundlagen der Beschreibung und Messung von Kompetenzen vorstellen und die Anwendung dieser Grundlagen im Rahmen unseres Projekts darstellen. Dabei kommt vor allem der Entwicklung von Kompetenzstruktur- und Kompetenzniveaumodellen eine besondere Bedeutung zu.

Exploiting Consumptive Behavior Based Data Mining of Mobile Environment
Creators: name: Patel, Jayeshkumar Madhubhai
Publisher: name: figshare
Year: 2019
Subjects: Applied Computer Science

description: Data mining is also called knowledge discovery in several database including mobile databases. In this paper, the consumptive behaviour based on data mining technology will be discussed and analyzed. Mobile search is becoming increasingly important for mobile users as mobile devices are more widely used. Mobile search is quite different from standard PC-based web search in a number of ways: (a) the user interfaces and I/O are limited by screen real estate; (b) key pads are tiny and inconvenient for use, (c) limited bandwidth and (d) costly connection fees. These limitationsresult in more navigational queries in the mobile search. Furthermore, user location, activities, preferences, and interaction history can also improve accuracy in determining relevance for mobile search. In the past, most personalized search algorithms are studied in the context of PC-based web search. Personalized mobile search should however play a bigger role at improving the user experiences. This paper focuses on the personalization strategies which explicitly and implicitly infer user search context at individual user level. We show that personalized mobile search perform well for ambiguous queries and localized searches. In this paper, a data mining method for generating mobile clients’ location-aware service rules are used and we use a data mining algorithm which involves mining for location-based services.
Bethe Approximation for a Semi-flexible Polymer Chain

description: We present a Bethe approximation to study lattice models of linear polymers. The approach is variational in nature and based on the cluster variation method (CVM). We focus on a model with $(i)$ a nearest neighbor attractive energy $ε_v$ between pair of non--bonded monomers, $(ii)$ a bending energy $ε_h$ for each pair of successive chain segments which are not collinear. We determine the phase diagram of the system as a function of the reduced temperature $t=\frac{T}{ε_v}$ and of the parameter $x=\frac{ε_h}{ε_v}$. We find two different qualitative behaviors, on varying $t$. For small values of $x$ the system undergoes a $θ$ collapse from an extended coil to a compact globule; subsequently, on decreasing further $t$, there is a first order transition to an anisotropic phase, characterized by global orientational order. For sufficiently large values of $x$, instead, there is directly a first order transition from the coil to the orientational ordered phase. Our results are in good agreement with previous Monte Carlo simulations and contradict in some aspects mean--field theory. In the limit of Hamiltonian walks, our approximation recovers results of the Flory-Huggins theory for polymer melting.

description: Most complex networks are not static, but evolve along time. Given a specific configuration of one such changing network, it becomes a particularly interesting issue to quantify the diversity of possible unfoldings of its topology. In this work, we suggest the concept of malleability of a network, which is defined as the exponential of the entropy of the probabilities of each possible unfolding with respect to a given configuration. We calculate the malleability with respect to specific measurements of the involved topologies. More specifically, we identify the possible topologies derivable from a given configuration and calculate some topological measurement of them (e.g. clustering coefficient, shortest path length, assortativity, etc.), leading to respective probabilities being associated to each possible measurement value. Though this approach implies some level of degeneracy in the mapping from topology to measurement space, it still paves the way to inferring the malleability of specific network types with respect to given topological measurements. We report that the malleability, in general, depends on each specific measurement, with the average shortest path length and degree assortativity typically leading to large malleability values. The maximum malleability was observed for the Wikipedia network and the minimum for the Watts-Strogatz model.

Pseudospin Anisotropy Classification of Quantum Hall Ferromagnets

description: Broken symmetry ground states with uniform electron density are common in quantum Hall systems when two Landau levels simultaneously approach the chemical potential at integer filling factor $ν$. The close analogy between these two-dimensional electron system states and conventional itinerant electron ferromagnets can be emphasized by using a pseudospin label to distinguish the two Landau levels. As in conventional ferromagnets, the evolution of the system's state as external field parameters are varied is expected to be sensitive to the dependence of ground state energy on pseudospin orientation. We discuss the predictions of Hartree-Fock theory for the dependence of the sign and magnitude of the pseudospin anisotropy energy on the nature of the crossing Landau levels. We build up a classification scheme for quantum Hall ferromagnets that applies for single layer and bilayer systems with two aligned Landau levels distinguished by any combination of real-spin, orbit-radius, or growth direction degree-of-freedom quantum numbers. The possibility of in-situ tuning between easy-axis and easy-plane quantum Hall ferromagnets is discussed for biased bilayer systems with total filling factors $ν=3$ or $ν=4$. Detailed predictions are made for the bias dependence of pseudospin reversal properties in $ν=3$ bilayer systems.

Assuming interference dominates noise power at the eavesdropper and at each legitimate user's receiver, the BS transmits information to the legitimate user with the $k$-th best (highest) signal-to-interference ratio. We derive a closed-form expression for the secrecy outage probability for an arbitrary $N$ and an asymptotic expression for a fixed $k$ and large $N$. Furthermore, we derive a closed form asymptotic expression for the ergodic secrecy capacity of the $k$-th best user and show that it scales like $O\left(\log(N)\right)$ for a fixed $k$ and large $N$.

description: This study aimed to apply aquathermolysis technology to remove thiophene sulfur in vacuum residue to obtain qualified petroleum coke products based on a well-designed Fe-Zr-Al catalyst. A coprecipitation method was first developed to synthesize Fe-Zr-Al composite metal oxide catalyst. The thiophene model oil was selected as the reaction system to investigate the process conditions. By adding surfactants into the reaction system to strengthen the mass transfer process of oil–water two-phase, the desulfurization rate of aquathermolysis was improved. It was shown in this study that under the conditions of oil–water ratio of 3:7, temperature of 280°C, pressure of 4 MPa and reaction duration of 60 h, the desulfurization rate could reach 44.39%. The further introduction of 2.4% Sorbitan oleate into the above reaction system could significantly enhance the desulfurization rate to 60.20%. Under the action of Fe2O3 lattice oxygen, thiophene was oxidized and C-S bond was broken, so as to achieve the purpose of desulfurization. The decomposition of water generated active oxygen to continuously replenish lattice oxygen of Fe2O3. The current founding can provide a new way for the effective desulfurization of vacuum residue to produce qualified petroleum coke products.

description: Context: In continuous deployment, software and services are rapidly deployed to end-users using an automated deployment pipeline. Defects in infrastructure as code (IaC) scripts can hinder the reliability of the automated deployment pipeline. We hypothesize that certain properties of IaC source code such as lines of code and hard-coded strings used as configuration values, show correlation with defective IaC scripts. Objective: The objective of this paper is to help practitioners in increasing the quality of infrastructure as code (IaC) scripts through an empirical study that identifies source code properties of defective IaC scripts. Methodology: We apply qualitative analysis on defect-related commits mined from open source software repositories to identify source code properties that correlate with defective IaC scripts. Next, we survey practitioners to assess the practitioner's agreement level with the identified properties. We also construct defect prediction models using the identified properties for 2,439 scripts collected from four datasets. Results: We identify 10 source code properties that correlate with defective IaC scripts. Of the identified 10 properties we observe lines of code and hard-coded string to show the strongest correlation with defective IaC scripts. Hard-coded string is the property of specifying configuration value as hard-coded string. According to our survey analysis, majority of the practitioners show agreement for two properties: include, the property of executing external modules or scripts, and hard-coded string. Using the identified properties, our constructed defect prediction models show a precision of 0.70~0.78, and a recall of 0.54~0.67.

description: De term ‘Smart City’ wordt steeds vaker genoemd als oplossing voor klimaat- en verstedelijkingsproblemen. Veel lokale overheden weten echter niet wat zij concreet kunnen doen om hun eigen Smart City-initiatief te ontwikkelen. In het onderzoek ‘Van Bouwstenen naar Smart City’ is onderzocht wat voor lokale overheden de bouwstenen zijn voor een succesvol proces tot de ontwikkeling van Smart City-initiatieven. Met behulp van een viertal Smart City-initiatieven in Nederland en gesprekken met betrokken partijen is gekomen tot vijftien ‘bouwstenen’ die lokale overheden concreet kunnen helpen bij de ontwikkeling van hun eigen Smart City-initiatief.

description: Monitoring is critical for providing robust, high performance Grid environment. Without monitoring mechanisms, it will be impossible to determine the status or health of environment. And so it will be difficult to use it effectively & efficiently.Monitoring data can be used for performance analysis, performance diagnosis, performance tuning, fault detection and scheduling.Due to the complexity and dynamics of grid, an improved monitoring system is needed which should have features like Grid Monitoring Architecture compliance, Scalability, Resource Performance Analysis and Forecasting, Directory service for events subscription & notification etc. In this paper, we have reviewed the grid monitoring system – ‘Autopilot’. ‘Autopilot’ is an infrastructure for real time adaptive control of parallel & distributive computing resources. The objective of ‘Autopilot’ is to create an environment which provides distributed applications with real time adaptive control so that they can automatically select & configure resource management features based on request patterns and observed system performance.This paper discusses the various performance parameters and criteria of the grid monitoring system – ‘Autopilot’ and provides some useful information as far as Grid Monitoring Architecture is concerned.

description: The analysis of the resonant spin-flavour (RSF) solutions to the solar neutrino problem in the framework of simplest analytic solutions to the solar magneto-hydrodynamics (MHD) equations is presented. We performed the global fit of the recent solar neutrino data, including event rates as well as day and night recoil electron spectra induced by solar neutrino interactions in SuperKamiokande. We compare quantitatively our simplest MHD-RSF fit with vacuum oscillation (VAC) and MSW--type (SMA, LMA and LOW) solutions to the solar neutrino problem using a common well-calibrated theoretical calculation and fit procedure and find MHD-RSF fit to be somewhat better than those obtained for the favored neutrino oscillation solutions. We made the predictions for future experiments to disentangle the MHD-RSF scenario from other scenarios.

description: Disky bulges in spiral galaxies are commonly thought to form out of disk materials (mainly) via bar driven secular processes, they are structurally and dynamically distinct from `classical bulges' built in violent merger events. We use high-resolution GTC/MEGARA integral-field unit spectroscopic observations of the Sa galaxy NGC 7025, obtained during the MEGARA commissioning run, together with detailed 1D and 2D decompositions of this galaxy's SDSS $i$-band data to investigate the formation of its disky (bulge) component which makes up $\sim 30\%$ of the total galaxy light. With a Sérsic index $n \sim 1.80 \pm 0.24$, half-light radius $R_{\rm e} \sim 1.70 \pm 0.43$ kpc and stellar mass $M_{*} \sim (4.34 \pm 1.70) \times10^{10} M_{\odot}$, this bulge dominates the galaxy light distribution in the inner $R \sim 15"$ ($\sim 4.7$ kpc). Measuring the spins ($λ$) and ellipticities ($ε$) enclosed within nine different circular apertures with radii $R \le R_{\rm e}$, we show that the bulge, which exhibits a spin track of an outwardly rising $λ$ and $ε$, is a fast rotator for all the apertures considered. Our findings suggest that this inner disky component is a pseudo-bulge, consistent with the stellar and dust spiral patterns seen in the galaxy down to the innermost regions but in contrast to the classical bulge interpretation favored in the past. We propose that a secular process involving the tightly wound stellar spiral arms of NGC 7025 may drive gas and stars out of the disk into the inner regions of the galaxy, building up the massive pseudo-bulge.

description: Triterpenoid saponins are the main active ingredients extracted from Camellia oleifera Abel. In this study, crude saponins (Tc) was extracted from tea seed pomace and purified to obtain total saponins (T0). We used a COSMOSIL C18-OPN to separate T0 into three fractions—highly polar saponins (T1), moderately polar saponins (T2), and weakly polar saponins (T3). HPLC-ESI-MS analysis revealed that T2 were mainly composed of components with m/z ([M-H]–) of 1201.5617, 1187.5822, 1245.5862, and 1215.5779. Cell cycle analysis showed that both T0 and T2 inhibited proliferation and induced S phase arrest of MCF-7 cells. Further cell invasion assays demonstrated T0 and T2 also significantly reduced the invasive potential of MCF-7 cells. So T2 extracted from tea seed pomace (Camellia oleifera) may have effective antitumor activity.

description: It is proved, that suggested by Jin modified formalism in the external-field method in QCD sum rules exactly coincides with the formalism used before. Therefore, unlike the claims of ref.1, this formalism cannot improve the predictability and reliability of external-field sum rule calculations in comparison with those, done by the standard approach.

description: In this paper, we study the Casimir force for a class of Lorentzian nonlocal field theories. These theories include a continuum of massive excitations. In this regard, the effect of continuum massive modes on Casimir force is of interest. We focus on the simplest case of two absorbing parallel planes in 1+1 dimensions, and we show that unlike local field theories, the thickness of the absorbing "walls" changes the value of Casimir force.

description: Chemical investigation of endophytic fungus Phyllosticta capitalensis, isolated from the hypocotyls of the Chinese mangrove Bruguiera sexangula led to the isolation of eight known secondary metabolites, including four meroterpenes guignardone A (1), 12-hydroxylated guignardone A (2), guignardone J (3), guignardone M (4), and four polyketides xenofuranone B (5), 6,8-dihydroxy-5-methoxy-3-methyl-1H-isochromen-1-one (6), regiolone (7), 3,4-dihydroxybenzoic acid (8). Their structures were elucidated unambiguously based on the comprehensive spectroscopic analysis and comparison with literature data. This is the first report of these compounds being isolated from this fungal species. All compounds isolated were subjected to antimicrobial and cytotoxic activities evaluation.
