description: The Anderson-Holstein model is studied in the framework of the semiclassical approximation. Analytic results for Kondo temperature renormalized by weak electron-phonon interaction and for phonon Green function are obtained, and they are interpreted from the viewpoint of dynamical mean field theory. Especially the isotope effect of the effective electron mass is discussed in the presence of strong electron correlation. The results are also compared with those by numerical renormalization group and other related works, and they are consistent with each other in their common domain of validity.

description: We investigate the magnetic symmetry of the topological antiferromagnetic material Mn$_3$Ge by using torque measurements. Below the Neel temperature, detailed angle-dependent torque measurements were performed on Mn$_3$Ge single crystals in directions parallel and perpendicular to the Kagome basal plane. The out-of plane torque data exhibit $\pm\sinθ$ and $\sin2θ$ behaviors, of which the former results from the spontaneous ferromagnetism within the basal plane and the latter from the in- and out-of-plane susceptibility anisotropy. The reversible component of the in-plane torque exhibits $\sin6φ$ behavior, revealing the six-fold symmetry of the in-plane magnetic free energy. Moreover, we find that the free energy minima are pinned to the direction of spontaneous ferromagnetism, which correspond to the maxima of the irreversible component of the in-plane torque. We provide an effective spin model to describe the in-plane magnetic anisotropy. Our results demonstrate that the ground state of Mn$_3$Ge is described by the coexistence of a strong six-fold antichiral order and a weak ferromagnetic order induced by second-order spin anisotropy.

description: Disaster monitoring is challenging due to the lake of infrastructures in monitoring areas. Based on the theory of Game-With-A-Purpose (GWAP), this paper contributes to a novel large-scale crowdsourcing disaster monitoring system. The system analyzes tagged satellite pictures from anonymous players, and then reports aggregated and evaluated monitoring results to its stakeholders. An algorithm based on directed graph centralities is presented to address the core issues of malicious user detection and disaster level calculation. Our method can be easily applied in other human computation systems. In the end, some issues with possible solutions are discussed for our future work.

description: The productive reuse of properties that are contaminated by hazardous substances has been increasingly emphasized by the U.S. Environmental Protection Agency and state and environmental agencies. As reuse on contaminated sites has grown, the documentation and analysis of the beneficial effects of such reuse also has expanded. This paper reviews the existing literature on the effects of reuse— summarizing the principal studies, measures of beneficial effects, and associated data— and discusses conceptual issues and difficulties that need to be addressed when estimating the beneficial effects of reuse. Studies included in the review represent a range of scales from the national to the local level and four different methodological approaches (routine data collection, case studies, survey-based methods, and analytical approaches). Directions for improving estimation of the beneficial effects include a wider variety of metrics for capturing the effects, an increased emphasis on the distribution of these effects, and a more rigorous economic accounting perspective.

description: Strong winds and ultraviolet (UV) radiation from O-type stars disrupt and ionize their molecular core birthplaces, sweeping up material into parsec-size shells. Owing to dissociation by starlight, the thinnest shells are expected to host low molecular abundances and therefore little star formation. Here, we expand previous maps taken with the IRAM 30m telescope and present square-degree 12CO and 13CO (J=2-1) maps of the wind-driven "Veil bubble'' that surrounds the Trapezium cluster and its natal Orion molecular core (OMC). Although widespread and extended CO emission is largely absent from the Veil, we show that several CO "globules'' exist and are embedded in the [CII]158um-bright shell that confines the bubble. This includes the first detection of quiescent CO at negative LSR velocities in Orion. Given the harsh UV irradiation conditions in this translucent material, the detection of CO globules is surprising. These globules are small (R=7,100 AU), not massive (M=0.3M_Sun), and are moderately dense: n_ H=4x10^4 cm^-3 (median values). They are confined by the external pressure of the shell, P_ext/k~10^7 cm^-3 K, and are likely magnetically supported. They are either transient objects formed by instabilities or have detached from pre-existing molecular structures, sculpted by the passing shock associated with the expanding shell and by UV radiation from the Trapezium. Some represent the first stages in the formation of small pillars, others of isolated small globules. Although their masses do not suggest they will form stars, one globule matches the position of a known YSO. The lack of extended CO in the "Veil shell'' demonstrates that feedback from massive stars expels, agitates, and reprocesses most of the disrupted molecular cloud gas, thereby limiting the star-formation rate in the region. The presence of globules is a result of this feedback.

Using a compressible liquid drop model with an extended Skyrme energy-density functional, we obtain the most stringent constraints to date on the transition pressure $P_{\rm cc}=0.33^{+0.07}_{-0.07}$ MeV fm$^{-3}$ and chemical potential $μ_{\rm cc}=12.6^{+1.8}_{-1.9}$ MeV (which control the mass, moment of inertia and thickness of a neutron star crust), the proton fractions that bracket the pasta phases $y_{\rm p}=0.115^{+0.016}_{-0.017}$ and $y_{\rm cc}=0.041^{+0.007}_{-0.006}$, as well as the relative mass and moment of inertia $ΔM_{\rm p} / ΔM_{\rm c}\approx ΔI_{\rm p} / ΔI_{\rm c} = 0.54^{+0.05}_{-0.09}$ and thickness $ΔR_{\rm p} / ΔR_{\rm c}=0.129^{+0.019}_{-0.030}$ of the layers of non-spherical nuclei (nuclear pasta) in the crust.

description: Motion of test particles along rotating curved trajectories is considered. The problem is studied both in the laboratory and the rotating frames of reference. It is assumed that the system rotates with the constant angular velocity $ω= const$. The solutions are found and analyzed for the case when the form of the trajectory is given by an Archimedes spiral. It is found that particles can reach infinity while they move along these trajectories and the physical interpretation of their behaviour is given. The analogy of this idealized study with the motion of particles along the curved rotating magnetic field lines in the pulsar magnetosphere is pointed out. We discuss further physical development (the conserved total energy case, when $ω\ne const$) and astrophysical applications (the acceleration of particles in active galactic nuclei) of this theory.

description: Quantum optimal control is an important technology that enables fast state preparation and gate design. In the absence of an analytic solution, most quantum optimal control methods rely on an iterative scheme to update the solution estimate. At present, the convergence rate of existing solvers is at most superlinear. This paper develops a new general purpose solver for quantum optimal control based on the PRojection Operator Newton method for Trajectory Optimization, or PRONTO. Specifically, the proposed approach uses a projection operator to incorporate the Schrödinger equation directly into the cost function, which is then minimized using a quasi-Newton method. At each iteration, the descent direction is obtained by computing the analytic solution to a Linear-Quadratic trajectory optimization problem. The resulting method guarantees monotonic convergence at every iteration and quadratic convergence in proximity of the solution. To highlight the potential of PRONTO, we present an numerical example that employs it to solve the optimal state-to-state mapping problem for a qubit and compares its performance to a state-of-the-art quadratic optimal control method.

Essays in economics of education

Publisher: name: No Publisher Supplied
Year: 2021

description: In Chapter 2, I analyze the effect of supplementary private schooling – cram schools and tutoring – on educational attainment and wages using the Korean Youth Panel 2007. I use the number of cram schools near the residence of a child at age 14 and cram school business hour regulations as instruments to examine the effects of cram schools and tutoring. I find that cram schools and tutoring have a large positive impact on the probability of enrollment in and graduation from a four-year college in Seoul by age 27. Although statistically insignificant, I find a negative impact of cram school and a large positive impact of tutoring on wages. However, the effects are close to zero if the final educational attainment is controlled. In Chapter 3, I study the response to Covid-19 of parental spending on supplementary education. Covid-19 has caused unprecedented social and economic shocks including disruption in public education. In countries such as South Korea, where the supplementary for-profit private education market is vast, supplementary private education could potentially help to compensate for the disruption. Alternatively, negative income shocks and uncertainty about future income coupled with restrictions on supplementary education could reduce demand. If higher-income families are more able to afford an increase in supplementary education, or have incomes less affected by Covid-19, the educational disruption could increase educational inequality. I use the Household Trend Survey of South Korea to examine the recent evolution of spending on supplementary private education. By using linear probability and Ordinary Least Square models, I find that the Covid-19 has negative effects which do not differ statistically significantly by household income. The reductions in spending on supplementary education are also similar for households with younger and older children.In Chapter 4, I examine changes in firms' hiring in response to an anti-discrimination provision. In July 2007, legislation prohibiting discriminatory treatment of temporary and agency workers came into force in South Korea. I exploit the staged introduction of the anti-discrimination provision by firm size to examine its impact on firms’ employment decisions. Regression discontinuity results using the Workplace Panel data suggest that firms of different sizes reacted differently. The effect on temporary employment is a statistically significant decline of 24 workers for firms with about 300 workers, while it is large and positive for firms with about 100 workers, though statistically insignificant. The effect on agency employment is large and positive for both firm types, though statistically insignificant. On the whole, these results do not reflect the expected employment declines. The effect on atypical employment, not directly targeted by the legislation, is large and positive for the larger firms but a statistically significant reduction of 13 workers for the smaller firms. The effects on permanent employment are small and statistically insignificant.

We parametrize these effects by dimension-six effective operators, and we also consider related simplified UV completions: scalar leptoquark and $W'$ models. We derive new constraints on these scenarios by using recent ATLAS measurements of differential cross sections of single top production in association with a $W$ boson, and also show how these limits will evolve with future data. We also describe how the limits can be significantly improved by using ratios of differential distributions with different flavors of leptons.

description: The role of the crystal lattice for the electronic properties of cuprates and other high-temperature superconductors remains controversial despite decades of theoretical and experimental efforts. While the paradigm of strong electronic correlations suggests a purely electronic mechanism behind the insulator-to-metal transition, recently the mutual enhancement of the electron-electron and the electron-phonon interaction and its relevance to the formation of the ordered phases have also been emphasized. Here, we combine polarization-resolved ultrafast optical spectroscopy and state-of-the-art dynamical mean-field theory to show the importance of the crystal lattice in the breakdown of the correlated insulating state in an archetypal undoped cuprate. We identify signatures of electron-phonon coupling to specific fully-symmetric optical modes during the build-up of a three-dimensional metallic state that follows charge photodoping. Calculations for coherently displaced crystal structures along the relevant phonon coordinates indicate that the insulating state is remarkably unstable toward metallization despite the seemingly large charge-transfer energy scale. This hitherto unobserved insulator-to-metal transition mediated by fully-symmetric lattice modes can find extensive application in a plethora of correlated solids.
Elasticity of polymer vesicles by osmotic pressure: an intermediate theory between fluid membranes and solid shells

description: The entropy of a polymer confined in a curved surface and the elastic free energy of a membrane consisting of polymers are obtained by scaling analysis. It is found that the elastic free energy of the membrane has the form of the in-plane strain energy plus Helfrich's curvature energy [Z. Naturforsch. C \textbf{28}, 693 (1973)]. The elastic constants in the free energy are obtained by discussing two simplified models: one is the polymer membrane without in-plane strains and asymmetry between its two sides, which is the counterpart of quantum mechanics in curved surface [Jensen and Koppe, Ann. Phys. \textbf{63}, 586 (1971)]; another is the planar rubber membrane with homogeneous in-plane strains. The equations to describe equilibrium shape and in-plane strains of the polymer vesicles by osmotic pressure are derived by taking the first order variation of the total free energy containing the elastic free energy, the surface tension energy and the term induced by osmotic pressure. The critical pressure, above which spherical polymer vesicle will lose its stability, is obtained by taking the second order variation of the total free energy. It is found that the in-plane mode also plays important role in the critical pressure because it couples with the out-of-plane mode. Theoretical results reveal that polymer vesicles possess the mechanical properties intermediate between fluid membranes and solid shells.

description: Compared to the use of conventional spot luminance meters, high dynamic range imaging (HDRI) offers significant advantages for luminance measurements in lighting research. Consequently, the reporting of absolute luminance data based on HDRI measurements has rapidly increased in technical lighting literature, with researchers using HDRI to address topics such as daylight distribution and discomfort glare. However, questions remain about the accuracy of luminance data derived from HDRI. This article reviewed published papers that reported potential sources of error in deriving absolute luminance values from high dynamic range imaging (HDRI) using a consumer grade digital camera, along with application papers that included an analysis of errors in HDRI-derived luminance values. Four sources of significant error emerged from the literature review: lens vignetting, lens flare, luminous overflow, and sensor spectral responsivity. The cause and magnitude for each source of error is discussed using the relevant findings from previous research and any available correction methods are presented. Based on the review, a set of recommendations was developed for minimizing the possible errors in HDRI luminance measurements as well as recommendations for future research using HDRI.

description: The article provides a theoretical and methodological analysis of the impact of globalization on the educa-tional system through the prism of sociological analysis and, at the same time, identifies the main causes and components of the globalization of education in the context of educational practices and discourses. In the modern modernized society, where a significant role is given to the processes of informatization, globalization, McDon-aldization, westernization, educational processes and their influence on the functioning of society are of extraor-dinary attention. The sociological dimension of education is to consider the latter in the context of social interaction as one of the subsystems of the social system, as well as as one of the most important social institutions, performing a number of vital functions.

description: There has been recent interest in a hybrid form of the celebrated conjectures of Hardy-Littlewood and of Chowla. We prove that for any $k,\ell\ge1$ and distinct integers $h_2,\ldots,h_k,a_1,\ldots,a_\ell$, we have $$\sum_{n\leq X}μ(n+h_1)\cdots μ(n+h_k)Λ(n+a_1)\cdotsΛ(n+a_{\ell})=o(X)$$ for all except $o(H)$ values of $h_1\leq H$, so long as $H\geq (\log X)^{\ell+ε}$. This improves on the range $H\ge (\log X)^{ψ(X)}$, $ψ(X)\to\infty$, obtained in previous work of the first author. Our results also generalize from the Möbius function $μ$ to arbitrary (non-pretentious) multiplicative functions.

description: A formalism for representing the fully relativistic propagator of the Rarita-Schwinger field in the nuclear medium is developed. Using a convenient basis for expanding the propagator, or the self energy, it is shown that they can be represented by 40 energy and momentum dependent quantities which can be combined into a 2x2 and a 6x6 matrix. In this way calculations reduce to matrix multiplication. Using the presented formalism the full relativistically covariant contribution of the pion-nucleon loop to the isobar self energy and propagator in isospin-symmetric spin-saturated nuclear medium is computed. Utilizing this propagator the photoabsorption cross-section on in-medium nucleons in the isobar region is calculated and the result compared with experimental data.

Smart reading instruction for ESL learners in the content area : SMARTboards and interactive learning
Creators: name: Wong, Melanie Mun Wai
Publisher: name: The University of British Columbia
Year: 2014

description: Turbill (2003) describes how some principals have "lamented that in spite of each classroom in their schools having at least one computer, teachers of the early years in particular, were reluctant, even resistant, to the integration of computers into their literacy curriculum" (p. 256). The growing resistance towards technology has motivated the writing of this paper. This graduating paper focuses on English as a Second Language (ESL) content reading vocabulary, technology and SMARTboards. As it was discovered in the literature, there is an overwhelming need for teachers, who teach ESL, to reevaluate the way they instruct their ESL students in reading. Research indicates that students need to be intentionally taught vocabulary (Kern, 1989 ; Laufer, 2003 ; Gunderson, 2009). "Both English and information technology are tools-to-allow individuals to participate fully in society" (Warshcauer, 2002, p. 456). One tool that can be used in the classroom is a SMARTboard. The literature surrounding Interactive Whiteboards has indicated that students have a positive perception of them (Beeland, 2002 ; Schut, 2007, ; Hall & Higgins, 2005). This paper explores the possibilities of using SMARTboards of teach content reading vocabulary in an academic core subject.

description: We resume the discussion about irradiation-driven mass transfer cycles in semi- detached compact binary systems. The analytical model that describes the onset of these cycles, which occur on a thermal timescale of the donor star, is reexamined. We take into account a contribution of the thermal relaxation which is not related to the irradiation of the donor star and which was neglected in previous studies. Cataclysmic variables (CVs) containing extended giant donors are more stable than previously thought. CVs close to the upper edge of the period gap can undergo cycles for low angular momentum loss rates, as they have been suggested by recent magnetic braking prescriptions, while they are stable for high braking rates. A model for the irradiation geometry that takes into account surface elements near the terminator of the donor star indicates that possibly also low-mass X-ray binaries (LMXBs) can undergo mass transfer cycles. Regarding the braking rate, which is necessary to drive cycles, basically the same restrictions apply for short period LMXBs as they do for short period CVs. We confirm that LMXBs containing giants can undergo cyles. In terms of an irradiation efficiency parameter αCVs are susceptible to the irradiation instability for α>= 0.1 while LMXBs are susceptible for α<= 0.1. The predictions of the analytical model are checked by the first long-term evolutionary computations of systems undergoing mass transfer cycles with full 1D stellar models. For unevolved main sequence (MS) and giant donors the analytic model provides reasonable values for the boundaries of the stable and unstable regions while CVs containing highly evolved MS donors are more stable at high braking rates than expected.Taking into account irradiation the minimum period of CVs is increased by up to 1-2 minutes, depending on α.

description: Distance measures provide the foundation for many popular algorithms in Machine Learning and Pattern Recognition. Different notions of distance can be used depending on the types of the data the algorithm is working on. For graph-shaped data, an important notion is the Graph Edit Distance (GED) that measures the degree of (dis)similarity between two graphs in terms of the operations needed to make them identical. As the complexity of computing GED is the same as NP-hard problems, it is reasonable to consider approximate solutions. In this paper we present a QUBO formulation of the GED problem. This allows us to implement two different approaches, namely quantum annealing and variational quantum algorithms that run on the two types of quantum hardware currently available: quantum annealer and gate-based quantum computer, respectively. Considering the current state of noisy intermediate-scale quantum computers, we base our study on proof-of-principle tests of their performance.

description: A theoretical model is developed and used to evaluate the effects of either a devaluation or revaluation upon production, consumption, trade and price of a particular commodity in both exporting and importing countries. This model is used to analyze the theoretical effects of a devaluation on the agricultural sector of an economy. One concludes that a devaluation will have only a small impact on agricultural trade. What effect there is will be primarily a price effect rather than a quantity effect. Therefore a country cannot necessarily look to its agricultural sector for the major contribution to improving the balance of payments position via a devaluation.
Grant-Free Massive Random Access With a Massive MIMO Receiver

description: We consider the problem of unsourced random access (U-RA), a grant-free uncoordinated form of random access, in a wireless channel with a massive MIMO base station equipped with a large number $M$ of antennas and a large number of wireless single-antenna devices (users). We consider a block fading channel model where the $M$-dimensional channel vector of each user remains constant over a coherence block containing $L$ signal dimensions in time-frequency. In the considered setting, the number of potential users $K_\text{tot}$ is much larger than $L$ but at each time slot only $K_a \ll K_\text{tot}$ of them are active. Previous results, based on compressed sensing, require that $K_a < L$, which is a bottleneck in massive deployment scenarios such as Internet-of-Things and U-RA. In the context of activity detection it is known that such a limitation can be overcome when the number of base station antennas $M$ is sufficiently large and a covariance based recovery algorithm is employed at the receiver. We show that, in the context of U-RA, the same concept allows to achieve high spectral efficiencies in the order of $\mathcal{O}(L \log L)$, although at an exponentially growing complexity. We show also that a concatenated coding scheme can be used to reduce the complexity to an acceptable level while still achieving total spectral efficiencies in the order of $\mathcal{O}(L/\log L)$.

description: This paper, therefore, has three objectives. The first is to extend the framework of the studies cited above to evaluate the potential net economic· benefits of programs such as Canada's. The second is to show, with an empirical analysis of price and margin deficiency programs for the Canadian pork sector, the actual benefits resulting from such programs. The third is to compare the stabilizing effects of these two policy instruments.

description: The study found the impact of the ways of non-breed bull calves’ keeping on the increase of their live weight gains: under the unleashed keeping the weight of bull calves of 18 months old was 328.9 kg, that is 612 g of average daily gain or 19.4% of relative gain, while their analogues had 454.3 kg, 877 g, 20.9%, respectively. It is proved that the live weight at the age of 18 months is 372.6 kg under the leashed keeping, while it is 482.3 kg under the unleashed one. The average daily gains of live weight under the improved technology are higher by 31.6% (with 60% kept) and by 33.6% (with 50% kept) compared with the current one. The energy value of 1 kg of edible carcasses in bull calves of the Ukrainian black-speckled dairy breed at the age of 18 months kept for the production of beef under the unleashed keeping is by 20% higher than under the leashed one (P<0.001), while their fatty tissue is on the contrary, but the qualitative indicator of the amount of protein is higher, which is a desirable factor for the production of beef.

description: The long-time kinetics of the spherical model in an external magnetic field and below the equilibrium critical temperature is studied. The solution of the associated stochastic Langevin equation is reduced exactly to a single non-linear Volterra equation. For a sufficiently small external field, the kinetics of the magnetization-reversal transition from the metastable to the ground state is compared to the ageing behaviour of coarsening systems quenched into the low-temperature phase. For an oscillating magnetic field and below the critical temperature, we find evidence for the absence of the frequency-dependent dynamic phase transition, which was observed previously to occur in Ising-like systems.

description: The some models of holographic dark energy for Randall-Sandrum brane are considered. For first class of dark energy models we take energy density in form $\sim L^{2γ-4}$ where $L$ is size of events horizon in Universe and $γ$ is parameter (Tsallis holographic energy). Analysis of observational data allows to define upper limit on value of $δ=ρ_{0}/2λ$ ($ρ_{0}$ is current energy density in the Universe and $λ$ is brane tension). Then we investigate models for which dark energy density has form $ρ_{de}=C^{2}L^{-2}-C_{1}^{2}H^{2}$ where $H$ is Hubble parameter.

description: After Reza Khan came to the power in Iran and established an oppressive regime in 1925, a wave of political pressure against national activists and communists swept the country, their mass arrests began, and Ghani Ibrahimi was also one of the victims of this process. He was arrested among his fellow countrymen, severely tortured in prison, and eventually exiled to Nahavand for a long time until the end of his life. Gani Ibrahim's two sons and three daughters, who were born and raised in his family, were nourished by his national liberation and revolutionary spirit. The eldest son of the family, Firudin Ibrahimi, grew up as a nationalist Azerbaijani fighter and became one of the greatest members of the “21 Azer movement”, during his adolescence and studying at the Faculty of Law of Tehran University. He took part in the establishment and activity of the Democratic Party of Azerbaijan, the National Assembly and the National Government with all his being, sacrificed his life and rose to the peak of martyrdom, was awarded the title of National Hero of Azerbaijan. Anushiravan, the third child of the family, came to the battlefield like his father Gani and his elder brother Firudin, fought for the freedom and independence of his homeland for many years, and finally sacrificed his life like his father and brother.
