description: A Markov model shows the degree of brand loyalty to Apple, Compaq, IBM, and Wyse personal computers by large corporate customers of Businessland, a large reseller of personal computers in the late 1980s and early 1990s. Because Businessland temporarily lost its franchise to carry Compaq for half a year in the middle of our sample, the model captures the effect on Businessland's sales of rival brands when a name brand is eliminated and then reintroduced. Large corporate customers were brand-loyal and relatively price insensitive. Their loyalty did not diminish over time. They did not view IBM-compatible computers as perfect substitutes. Eliminating and then reintroducing a brand has different short- and long-run effects. It is difficult to explain which firms diversify, but, contrary to reports in the popular press, most firms used both Apple and IBM-compatible machines.

description: A recent thrust in turbulence closure modeling research is to incorporate machine learning (ML) elements, such as neural networks, for the purpose of enhancing the predictive capability to a broader class of flows. Such a turbulence closure framework entails solving a system of equations comprised of ML functionals coupled with traditional (physics-based - PB) elements. While combining closure elements from fundamentally different ideologies can lead to unprecedented progress, there are many critical challenges that must be overcome. This study examines three such challenges: (i) Physical compatibility (or lack thereof) between ML and PB constituents of the modeling system of equations; (ii) Internal (self) consistency of the ML training process; and (iii) Formulation of an optimal objective (or loss) function for training. These issues are critically important for generalization of the ML-enhanced methods to predictive computations of complex engineering flows. Training and implementation strategies in current practice that may lead to significant incompatibilities and inconsistencies are identified. Using the simple test case of turbulent channel flow, key deficiencies are highlighted and proposals for mitigating them are investigated. Compatibility constraints are evaluated and it is demonstrated that an iterative training procedure can help ensure certain degree of consistency. In summary, this work develops foundational tenets to guide development of ML-enhanced turbulence closure models.

description: This paper presents a new generalized maximum entropy (GME) approach to estimation of sample-selection models with small data sets, such as are found in many empirical agricultural economic analysis. For small samples, the GME approach produces more stable estimates and has smaller mean square error measures than other well-known estimators such as ordinary least squares, Heckman's two-step method, full-information maximum likelihood, and Ahn and Powell's method. The technique is used to analyze whether hired agricultural workers will work in piece-rate or time-rate jobs and to compare female-male wage differentials for both types of jobs.
Supporting teachers in their implementation of mathematics instruction for understanding : the intermediate mathematics teachers’ inquiry group
Creators: name: Martin, Janet
Publisher: name: University of British Columbia
Year: 2009

description: Current reform ideas in mathematics education recommend that instruction focus on teaching all students to learn and understand mathematics, and make connections within mathematics and applications of mathematics. Implementation of these ideas requires teachers to make use of teaching practice that, for most of them, is different from their previous experience in teaching mathematics. Past attempts to implement lasting change in education through the legislation of new curriculum have not proven successful. In addition, professional development opportunities that offer isolated, one-time workshops have also failed to support teachers working towards change in their teaching practice. The Intermediate Mathematics Teachers' Inquiry Group (IMTIG), was a professional development model, designed to support teachers as they worked with mathematics reform ideas to improve their teaching practice and hence, student learning. The format of this project incorporated recommendations from other teaching learning communities, adapted to fit our local context. The study involved the participation of seven intermediate mathematics teachers and two university participants, who all met regularly over a period of four months. Teacher learning took place in two contexts: during group meetings and in individual teachers' classrooms. The community of support and collaboration that developed within IMTIG was a major reason for IMTIG's success. Participants valued the regular meetings with colleagues to discuss new ideas, and share experiences and resources. Group discussions dealt with issues related to mathematics reform ideas, and assisted teachers as they worked to adapt and implement IMTIG teaching practice in their classrooms. Upon completion of the EVITIG project, all participants indicated their willingness to continue using teaching practice related to mathematics educational reform. The role of the two university participants within EVITIG was to introduce new ideas to the group, to provide access to resources, and to help the group maintain a focus on the goal of improving mathematics teaching to best teach for student understanding. The two university participants in IMTIG played different roles within the group. One role was to share relevant resources and present IMTIG teaching practice, and the second role was to introduce ideas from research and theory and to encourage teacher reflection.

description: Rural development policy since the 1960's has sought to arrest economic decline in rural areas and reduce the disparity between rural and urban incomes. And between 1968 and 1975, some progress was made. During this period, personal income in nonmetro counties grew 25 percent faster than in metro counties, reversing a trend during the fifties and sixties. Nonmetro income grew substantially faster than metro income in all regions except the South, but even there, nonmetro counties had a slight growth advantage

description: Fe$_{3-x}$GeTe$_2$ is a layered van der Waals magnetic material with a relatively high ordering temperature and large anisotropy. While most studies have concluded the interlayer ordering to be ferromagnetic, there have also been reports of interlayer antiferromagnetism in Fe$_{3-x}$GeTe$_2$. Here, we investigate the interlayer magnetic ordering by neutron diffraction experiments, scanning tunneling microscopy (STM) and spin-polarized STM measurements, density functional theory plus U calculations and STM simulations. We conclude that the layers of Fe$_{3-x}$GeTe$_2$ are coupled ferromagnetically and that in order to capture the magnetic and electronic properties of Fe$_{3-x}$GeTe$_2$ within density functional theory, Hubbard U corrections need to be taken into account.

description: We analyze the consumer welfare effects of increased food and energy prices and find that the own-price elasticities of both food and energy are relatively inelastic, which explain well the dynamics of the recent soaring food and energy prices. The estimated demand elasticities are then used to analyze the consumer welfare effects of price changes in food and energy. The results indicate that an increase of food and energy prices would incur a substantial consumer welfare loss, which is a heavy burden for low income households.

description: Many social and biological networks consist of communities - groups of nodes within which connections are dense, but between which connections are sparser. Recently, there has been considerable interest in designing algorithms for detecting community structures in real-world complex networks. In this paper, we propose an evolving network model which exhibits community structure. The network model is based on the inner-community preferential attachment and inter-community preferential attachment mechanisms. The degree distributions of this network model are analyzed based on a mean-field method. Theoretical results and numerical simulations indicate that this network model has community structure and scale-free properties.

description: We demonstrate and characterize the transfer of a levitating silica nanosphere between two optical tweezers, at low pressure. Both optical traps are mounted on the heads of optical fibers and placed on translation stages in vacuum chambers. Our setup allows to physically separate the particle loading environment from the experimental chamber, where the second tweezer can position the particle inside a high Finesse optical cavity. The separation prevents from spoiling the cavity mirrors and the chamber cleanliness during the particle loading phase. Our system provides a very reliable and simply reproducible protocol for preparing cavity optomechanics experiments with levitating nanoparticles, opening the way to systematic studies of quantum phenomena and easing the realization of sensing devices.

description: We discuss a Randall-Sundrum-type two D-braneworld model in which D-branes possess different values of the tensions from those of the charges, and derive an effective gravitational equation on the branes. As a consequence, the Einstein-Maxwell theory is realized together with the non-zero cosmological constant. Here an interesting point is that the effective gravitational constant is proportional to the cosmological constant. If the distance between two D-branes is appropriately tuned, the cosmological constant can have a consistent value with the current observations. From this result we see that, in our model, the presence of the cosmological constant is naturally explained by the presence of the effective gravitational coupling of the Maxwell field on the D-brane.

description: We consider binary liquid mixtures close to their critical points confined by two parallel, geometrically flat but chemically structured, substrates. Universal order parameters profiles are calculated within mean field theory for periodic patterns of stripes with alternating preferences for the two species of the mixture and with different relative positions of the two substrates. From the order parameters profiles the effective forces between the two plates are derived. The tuning of Casimir amplitudes is discussed.
Stable Pentaquarks from Strange Chiral Multiplets

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The assumption of strong diquark correlations in the QCD spectrum suggests flavor multiplets of hadrons that are degenerate in the chiral limit. Generally it would be unnatural for there to be degeneracy in the hadron spectrum that is not protected by a QCD symmetry. Here we show --for pentaquarks constructed from diquarks-- that these degeneracies can be naturally protected by the full chiral symmetry of QCD. The resulting chiral multiplet structure recovers the ideally-mixed pentaquark mass spectrum of the diquark model, and interestingly, requires that the axial couplings of the pentaquarks to states outside the degenerate multiplets vanish in the chiral limit. This result suggests that if these hadrons exist, they are stable in the chiral limit and therefore have widths that scale as the fourth power of the kaon mass over the chiral symmetry breaking scale. Natural-size widths are of order a few MeV.

Tidal driving of inertial modes of Maclaurin spheroids

Year: 2020

description: We examine the inertial modes of vibration of a Maclaurin spheroid and determine how they are driven by an external tidal field, either Newtonian (gravitoelectric) or post-Newtonian (gravitomagnetic). The context and motivation for this work come from the realization that inertial modes of rotating neutron stars can be resonantly excited in binary inspirals, with a measurable effect on the phasing of the emitted gravitational waves. We aim to provide additional insights into this phenomenon. We calculate how the frequencies of the relevant inertial modes, and their overlap integrals with the tidal forces, vary as the star's rotation rate increases, spanning almost the full range between zero rotation and the mass-shedding limit. We prove that a single inertial mode couples to a Newtonian tidal field; overlap integrals with all other modes vanish. We prove also that four inertial modes couple to a post-Newtonian, gravitomagnetic tidal field; overlap integrals with all other modes vanish. Finally, we determine the rather extreme conditions under which the gravitoelectric driving of inertial modes dominates over the gravitomagnetic driving.

description: The Advanced Camera for Surveys on board the Hubble Space Telescope has been used to obtain deep high-resolution images of the giant early-type galaxy NGC 1316 which is an obvious merger remnant. These observations supersede previous, shallower observations which revealed the presence of a population of metal-rich globular clusters of intermediate age (~ 3 Gyr). We detect a total of 1496 cluster candidates, almost 4 times as many as from the previous WFPC2 images. We confirm the bimodality of the color distribution of clusters, even in V-I, with peak colors 0.93 and 1.06. The large number of detected clusters allows us to evaluate the globular cluster luminosity functions as a function of galactocentric radius. We find that the luminosity function of the inner 50% of the intermediate-age, metal-rich (`red') population of clusters differs markedly from that of the outer 50%. In particular, the luminosity function of the inner 50% of the red clusters shows a clear flattening consistent with a turnover that is about 1.0 mag fainter than the turnover of the blue clusters. This constitutes the first direct evidence that metal-rich cluster populations formed during major mergers of gas-rich galaxies can evolve dynamically (through disruption processes) into the red, metal-rich cluster populations that are ubiquitous in `normal' giant ellipticals.

description: Research in the social sciences and psychology has shown that the persuasiveness of an argument depends not only the language employed, but also on attributes of the source/communicator, the audience, and the appropriateness and strength of the argument's claims given the pragmatic and discourse context of the argument. Among these characteristics of persuasive arguments, prior work in NLP does not explicitly investigate the effect of the pragmatic and discourse context when determining argument quality. This paper presents a new dataset to initiate the study of this aspect of argumentation: it consists of a diverse collection of arguments covering 741 controversial topics and comprising over 47,000 claims. We further propose predictive models that incorporate the pragmatic and discourse context of argumentative claims and show that they outperform models that rely only on claim-specific linguistic features for predicting the perceived impact of individual claims within a particular line of argument.

Master equation theory applied to the redistribution of polarized radiation in the weak radiation field limit. VI. Application to the Second Solar Spectrum of the Na I D1 & D2 lines: convergence

description: This paper presents a numerical application of a self-consistent theory of partial redistribution in non-LTE conditions, developed in previous papers of the series. The code was described in a previous paper of this series. However, in that previous paper (number IV of the series), the numerical results were unrealistic. The present paper presents an approximation, which was able to restore the reliability of the outgoing polarization profiles. The convergence of the results is also proved. It is demonstrated that the step increment decreases like 1/N^a, with a > 1, so that the results series behaves like a Riemann series, which is absolutely convergent. However, agreement between the computed and observed linear polarization profiles remains qualitative only. The discrepancy is assigned to the plane parallel atmosphere model, which is insufficient to describe the chromosphere, where these lines are formed. As all the integrals are numerical in the code, it could probably be adapted to more realistic and higher dimensioned model atmospheres. However, it is time consuming for lines having an hyperfine structure as the Na I D lines are. The net linear polarization observed in Na I D1 with the polarimeter ZIMPOL mounted on the McMath-Pierce telescope at Kitt Peak is not confirmed by the present calculations and could be an artefact of instrumental polarization. The presence of instrumental polarization could be confirmed by the higher linear polarization degree observed by this instrument in Na I D2 line center, with respect to the present calculation result, where the magnetic field is not accounted for, when the Hanle effect acts as a depolarizing effect in the Second Solar Spectrum. The observed linear polarization excess is found of the same order of magnitude 0.1% in both line centers, which is also comparable to the instrumental polarization compensation level of this experiment.

A case study of teachers’ experiences participating in a Ministry of Education technology initiative
Creators: name: Dean, Virginia Clare
Publisher: name: University of British Columbia
Year: 2009

description: This case study was conducted in order to understand the challenges and experiences of teachers from the Westview School District (pseudonym) participating in the British Columbia Ministry of Education's Grades 6-9 Information and Communication Technology (ICT) Initiative. The four levels of teachers for this study included: 1. staff from the ministry responsible for either coordinating or managing the Initiative; 2. staff from the district responsible for implementing the Initiative in the district; 3. mentors who were the teachers responsible for supporting mentees as they implemented ICTs into their practice; 4. mentees who were the teachers implementing ICTs into their teaching practice. The research questions that framed this study are: 1. By participating in the Initiative did teachers make any changes to their practice, confidence levels and attitudes towards information and communication technology? 2. How effective was the mentorship model for implementing information and communication technology? 3. What factors are necessary to support the adoption of information and communication technology in teaching practice? Three methods of data collection were used including interviews, a personal journal and observation of mentors and mentees. Teachers were given a choice of being interviewed using either personal, email or mail interviews. From the analysis of the data, clusters of themes of experiences were identified including; teachers' motivations and feelings; difficulties with the mentoring relationship; technology issues; satisfaction and dissatisfaction with the Initiative. In conclusion, outside forces that are beyond the control of educators can seriously affect the outcome of educational initiatives. In order to counteract these forces, other means of support including funding must be made available. Time is required to make substantial changes to teachers' practice and students' learning. Therefore, technology implementation must be supported over a period of more than one and a half years before noticeable changes can be made. Mentoring is not a relationship that can be created for or imposed on people and it requires time to develop. The complexities of the combination of needs, personalities and skills make mentoring a difficult relationship to create through a one time initiative.

description: We propose a protocol to realize atomic nonadiabatic holonomic quantum computation (NHQC) with two computational atoms and an auxiliary atom. Dynamics of the system is analyzed in the regime of Rydberg blockade, and robust laser pulses are designed via reverse engineering, so that quantum gates can be easily realized with high fidelities. In addition, we also study the evolution suffering from dissipation with a master equation. The result indicates that decays of atoms can be heralded by measuring the state of the auxiliary atom, and nearly perfect unitary evolution can be obtained if the auxiliary atom remains in its Rydberg state. Therefore, the protocol may be helpful to realize NHQC in dissipative environment.

description: Electron spin resonance (ESR) experiments were performed with antiferromagnetic MnO confined within a porous vycor-type glass and within MCM-type channel matrices. A signal from confined MnO shows two components from crystallized and amorphous MnO and depends on the pore topology. Crystallized MnO within a porous glass shows a behavior having many similarities to the bulk. In contrast with the bulk the strong ESR signal due to disordered "surface" spins is observed below the magnetic transition. With the decrease of channel diameter the fraction of amorphous MnO increases while the amount of crystallized MnO decreases. The mutual influence of amorphous and crystalline MnO is observed in the matrices with a larger channel diameter. In the matrices with a smaller channel diameter the ESR signal mainly originates from amorphous MnO and its behavior is typical for the highly disordered magnetic system.

description: We present a calculation of radiative pion photoproduction in the framework of covariant chiral perturbation theory with explicit $Δ(1232)$ degrees of freedom. The analysis is performed employing the small scale expansion scheme adjusted for the $Δ$ region. Depending on the channel, we include contributions up to next-to-next-to-leading order. We fit the available experimental data for the reaction $ γp\toγpπ^0 $ and extract the value of the $Δ^+$ magnetic moment. Errors from the truncation of the small scale expansion are estimated using the Bayesian approach. We compare our results both with the previous studies within the $δ$-expansion scheme and with the $Δ$-less theory. We also give predictions for radiative charged-pion photoproduction.

description: We examine the sensitivity of neutrino emissions to stellar evolution models for a 15$M_\odot$ progenitor, paying particular attention to a phase prior to the collapse. We demonstrate that the number luminosities in both electron-type neutrinos ($ν_e$) and their anti-partners ($\barν_e$) differ by more than an order of magnitude by changing spatial resolutions and nuclear network sizes on stellar evolution models. We also develop a phenomenological model to capture the essential trend of the diversity, in which neutrino luminosities are expressed as a function of central density, temperature and electron fraction. In the analysis, we show that neutrino luminosity can be well characterized by these central quantities. This analysis also reveals that the most influential quantity to the time evolution of $ν_e$ luminosity is matter density, while it is temperature for $\barν_e$. These qualitative trends will be useful and applicable to constrain the physical state of progenitors at the final stages of stellar evolution from future neutrino observations, although more detailed systematic studies including various mass progenitors are required to assess the applicability.

description: We consider QCD tt~Z production at the LHC with Z->\barννand all-hadronic tt~ decays, i.e. pp -> p_T(miss)bb~+4 jets, as a tool to measure ttZ couplings. This channel has a significantly larger cross section than those where the Z boson decays leptonically. However, tt~, bb~+4 jet, tt~j and tt~jj production give rise to potentially large backgrounds. We show that these processes can be suppressed to an acceptable level with suitable cuts, and find that adding the p_T(miss)bb~+4 jet channel to the final states used in previous ttZ couplings analyses will improve the sensitivity by 10-60%. We also discuss how the measurement of the ttZ couplings may constrain Little Higgs models.

description: CO2 reichert in sich der Atmosphäre an. Daher ist die Summe an CO2-Emissionen entscheidend für die Einhaltung bestimmter Grenzen der Erderwärmung (Budgeteigenschaft von CO2). Daher sollten sich NDCs an einem verbleibenden globalen CO2-Budget orientieren.

Bei der Umsetzung stellen sich jedoch folgende Fragen, die zwar wissenschaftlich basiert, aber letztendlich politisch beantwortet werden müssen:

An welchem global verbleibenden CO2-Budget sollen sich Staaten bei ihren NDCs orientieren?

An welcher Aufteilung eines globalen CO2-Budgets sollen sich Staaten bei ihren NDCs orientieren?

Wie kann ein daraus resultierendes national verbleibendes CO2-Budget in einen sinnvollen Emissionspfad übersetzt werden?

Das Extended Smooth Pathway Model (ESPM) bietet einen Rahmen, in dem diese Fragen mit nachvollziehbaren Ergebnissen beantworten werden können.

Wenn die Vertragsstaaten bei ihren NDCs ein dahinterstehendes globales CO2-Budget und einen dahinterstehenden Verteilungsschlüssel transparent machen, kann dies einen Diskurs in Gang setzen, der zu konvergierenden globalen Orientierungsgrößen führt und damit zu in Summe Paris-kompatiblen NDCs beiträgt.

description: We study the Abelian sandpile model on Z^d. In dimensions at least 3 we prove existence of the infinite volume addition operator, almost surely with respect to the infinite volume limit mu of the uniform measures on recurrent configurations. We prove the existence of a Markov process with stationary measure mu, and study ergodic properties of this process. The main techniques we use are a connection between the statistics of waves and uniform two-component spanning trees and results on the uniform spanning tree measure on Z^d.
description: First version: LaTeX; 29 pages. Revised version: LaTeX; 29 pages. The main result of the paper has been extended to all dimensions at least 3, with a new and simplyfied proof of finiteness of the two-component spanning tree. Second revision: LaTeX; 32 pages
A first XMM-Newton look at the most X-ray-luminous galaxy cluster RX J1347.5-1145

description: We present the first results from an XMM-Newton observation of RX J1347.5-1145 (z=0.451), the most luminous X-ray cluster of galaxies currently known, with a luminosity L_X = 6.0 \pm 0.1 \times 10^{45} erg/s in the [2-10] keV energy band. The cluster has an overall temperature of kT=10.0 \pm 0.3 keV and is not isothermal: the temperature profile shows a decline in the outer regions and a drop in the centre, indicating the presence of a cooling core. The spectral analysis identifies a hot region at radii 50-200 kpc to south-east of the main X-ray peak, at a position consistent with the subclump seen in the X-ray image. Excluding the data of the south-east quadrant, the cluster appears relatively relaxed and we estimate a total mass within 1 Mpc of 1.0 \pm 0.2 \times 10^{15} M_sun.

description: Changes and trends in farm productivity have been of intense interest to many involved with agriculture. This study used data envelopment analysis (DEA) to estimate the output-oriented Malmquist total factor productivity (TFP) index from panel data for 1993-2006 for farms in Southern Minnesota. Bootstrap methods were used to estimate confidence intervals for the productivity, efficiency change and technical change indices. The model included three inputs (labor, land and immediate expenditures) and six outputs (corn, soybean, milk, hog, beef, and nonfarm income). Productivity growth was found to be positive during the period, with an average annual productivity growth of 6.6 percent. However, TFP growth has been slowing down in recent years and indeed negative in 2000/01, 2002/03 and 2005/06. In the second stage of the analysis, the significance of various factors that might affect farm performance was estimated. Farm size (as measured by the log of farm income) was correlated with higher productivity which may help explain the increase in farm size in Minnesota farms in recent years. Government subsidies were found to have a negative impact on farm performance supporting the argument that agricultural subsidies may create disincentives for farmers to improve their productivity and efficiency. A higher nonfarm income ratio was positively related with higher productivity growth. A higher proportion of hired labor has a negative effect implying family labor is more crucial than hired labor in improving productivity.
