Targeted free energy perturbation revisited: Accurate free energies from mapped reference potentials

description: We present an approach that extends the theory of targeted free energy perturbation (TFEP) to calculate free energy differences and free energy surfaces at an accurate quantum mechanical level of theory from a cheaper reference potential. The convergence is accelerated by a mapping function that increases the overlap between the target and the reference distributions. Building on recent work, we show that this map can be learned with a normalizing flow neural network, without requiring simulations with the expensive target potential but only a small number of single-point calculations, and, crucially, avoiding the systematic error that was found previously. We validate the method by numerically evaluating the free energy difference in a system with a double-well potential and by describing the free energy landscape of a simple chemical reaction in the gas phase.

Translating and writing processes of adult second language learners

description: While translation in L2 learning/teaching has been viewed negatively since the 1950s in North America, in the late 1980s a re-evaluation of translation has begun (Duff, 1989). The purpose of this research is to explore text-level translation from the learner’s perspective, as this kind of research, at present, remains quite scarce (Krings, 1987). This study focuses on text-level translation as a useful component of second language (L2) learning/teaching. Adult L2 learners’ translation processes and performance are examined and contrasted with the same group’s Li and L2 writing performance. Twenty-two Japanese ESL students studying at a Canadian college performed three tasks individually (translation from Li into L2, Li writing, L2 writing), thinking aloud. Their writing samples were evaluated, and think-aloud protocols were analyzed, supplemented by interviews and text analyses. The data were analyzed with attention given to four recent cognitive theories of language learning: Cummins’ theories (1986) of cross-linguistic interdependence of cognitive academic skills; Schmidt’s “conscious attention” (1990); Swain’s “i+1 output” hypothesis (1985); and McLaughlin’s “restructuring” (1 990b). Findings: 1) The correlations of the quality of translation, Li writing, and L2 writing of L2 learners (whose Li writing skills are still developing) were not significant. 2) The learners’ conscious attention to language use was high in the translation task, but unexpectedly low in the L2 writing. Their language use was more sophisticated in the translation than in the L2 writing. 3) Some students preferred translation tasks to L2 writing tasks, expressing their views which were consistent with the “i+1 output” hypothesis. 4) Contrary to general expectation about student translations, the students did not translate word for word; they often restructured Li/L2 correspondences, and examples of “restructuring” were not limited to the word level. General conclusions: Cross-linguistic interdependence among translation, Li writing, and L2 writing was not confirmed clearly. However, there was evidence that translation processes prompted conscious attention, “i+1 output”, and restructuring, which some consider to be necessary for second language learning. Thus translation in L2 learning deserves a closer look as it provides potential opportunities for learners to learn a second language.

description: Optically and magnetically active point defects in semiconductors are interesting platforms for the development of solid-state quantum technologies. Their optical properties are usually probed by measuring photoluminescence spectra, which provide information on excitation energies and on the interaction of electrons with lattice vibrations. We present a combined computational and experimental study of photoluminescence spectra of defects in diamond and SiC, aimed at assessing the validity of theoretical and numerical approximations used in first principles calculations, including the use of the Franck-Condon principle and the displaced harmonic oscillator approximation. We focus on prototypical examples of solid-state qubits, the divacancy centers in SiC and the nitrogen-vacancy in diamond, and we report computed photoluminescence spectra as a function of temperature that are in very good agreement with the measured ones. As expected we find that the use of hybrid functionals leads to more accurate results than semilocal functionals. Interestingly our calculations show that constrained density functional theory (CDFT) and time-dependent hybrid DFT perform equally well in describing the excited state potential energy surface of triplet states; our findings indicate that CDFT, a relatively cheap computational approach, is sufficiently accurate for the calculations of photoluminescence spectra of the defects studied here. Finally, we find that only by correcting for finite-size effects and extrapolating to the dilute limit, one can obtain a good agreement between theory and experiment. Our results provide a detailed validation protocol of first principles calculations of photoluminescence spectra, necessary both for the interpretation of experiments and for robust predictions of the electronic properties of point defects in semiconductors.

description: Two- and three-body correlations of incompressible quantum liquids are studied numerically. Pairing of composite fermions (CFs) in the 1/3-filled second CF Landau level is found at nu_e=4/11. It is explained by reduced short-range repulsion due to ring-like single-particle charge distribution. Although Moore-Read state of CFs is unstable in the 1/2-filled second CF level, condensation of its quasiholes is a possible origin of incompressibility at nu_e=4/11. Electron pairing occurs at nu_e=7/3 and 13/3, but with different pair-pair correlations. Signatures of triplets are found at higher fillings.

description: This paper examines the use of a hierarchical coevolutionary genetic algorithm under different partnering strategies. Cascading clusters of sub-populations are built from the bottom up, with higher-level sub-populations optimising larger parts of the problem. Hence higher-level sub-populations potentially search a larger search space with a lower resolution whilst lower-level sub-populations search a smaller search space with a higher resolution. The effects of different partner selection schemes amongst the sub-populations on solution quality are examined for two constrained optimisation problems. We examine a number of recombination partnering strategies in the construction of higher-level individuals and a number of related schemes for evaluating sub-solutions. It is shown that partnering strategies that exploit problem-specific knowledge are superior and can counter inappropriate (sub)fitness measurements.

description: Imaging dynamical processes at interfaces and on the nanoscale is of great importance throughout science and technology. While light-optical imaging techniques often cannot provide the necessary spatial resolution, electron-optical techniques damage the specimen and cause dose-induced artefacts. Here, Optical Near-field Electron Microscopy (ONEM) is proposed, an imaging technique that combines non-invasive probing with light, with a high spatial resolution read-out via electron optics. Close to the specimen, the optical near-fields are converted into a spatially varying electron flux using a planar photocathode. The electron flux is imaged using low energy electron microscopy, enabling label-free nanometric resolution without the need to scan a probe across the sample. The specimen is never exposed to damaging electrons.

Our main focus is the variation of the Mahler measure when the base group is changed. In particular, we study how to obtain the Mahler measure over an infinite group as limit of Mahler measures over finite groups, for example, in the classical case of the free abelian group or the infinite dihedral group, and others.

description: Critical temperature, $T_c$, and the transition width, $Δ$$T_c$, are two primary parameters of the superconducting transition. The latter parameter reflects the superconducting state disturbance originating from the thermodynamic fluctuations, atomic disorder, applied magnetic field, the presence of secondary crystalline phases, applied pressure, etc. Recently, Hirsch and Marsiglio (2020 arXiv:2012.12796) performed an analysis of the transition width in several near-room-temperature superconductors (NRTS) and reported that the reduced transition width, $Δ$$T_c$$/$$T_c$, in these materials does not follow a conventional trend of transition width broadening on applied magnetic field observed in low- and high-$T_c$ superconductors. Here we present thorough mathematical analysis of the magnetoresistive data, $\it{R(T,B)}$, for the high-entropy alloy $(ScZrNb)_{0.65}$$[RhPd]_{0.35}$ and hydrogen-rich superconductors of Im-3m-$H_{3}S$, C2/m-$LaH_{10}$ and P63/mmc-$CeH_9$. We found that the reduced transition width, $Δ$$T_c$$/$$T_c$, in these materials does follow a conventional broadening trend on applied magnetic field.

description: Storytelling is a powerful way to transfer meanings, and websites constitute a multidimensional and interactive storytelling environment. With the rise of the Web into an essential part of our everyday lives, the existence of a web presence has become vital. It is therefore important for users who lack coding skills to be able to deliver successful websites. Web building platforms that have emerged in the past few years offer this possibility. This dissertation illustrates a method that non-developers can adopt in order to create a quality non-linear storytelling environment delivered through the Web by using these platforms, in combination with the foundations that web development and web design theories provide
A multiple intelligence view of learning at the high school level
Creators: name: Weber, Ellen
Publisher: name: University of British Columbia
Year: 2009

description: This study drew upon a constructivist and Howard Gardner’s multiple intelligence view of learning, to develop an interactive curriculum development model involving high school students and teachers. Eight grade ten students contributed in a central way to the study, a factor precipitated by my intention to emphasize students’ perspectives concerning their individual abilities and interests, and the way in which the high school curriculum did or did not accommodate these. Four grade ten teachers also participated in the task of identifying the degree to which students’ individual differences can be accommodated in an integrated high school curriculum. The study, conducted over a ten-month period during one school-year, addressed three questions. 1) What is the nature of the curriculum development process when high school students and teachers in their classroom practices, apply ideas congruent with Multiple Intelligence Theory, in order to address individual student differences, within the traditional constraints of a high school? How can these processes be incorporated into a model? 2) What was the role of the students in the development of the Multiple Intelligence Theory Application Model? and, 3) What was the role of the teachers in the development of the Multiple Intelligence Theory Application Model? My response to these questions involved the monitoring of students’ perspectives concerning their interests and abilities as reflected by both their current curriculum and the integrated curricular unit prepared by the teachers. The students’ and teachers’ perspectives are discussed and examined by means of in-depth interviews, interactive group discussions, and field notes and documentation of the collaborative processes involved in developing the integrated curriculum unit. The analysis of the findings suggests that change within the curriculum content, consistent with a constructivist and MI view of learning, would enable students to develop further their individual differences. Such change is endorsed particularly by the high school student participants. The study also examines the usefulness of the MITA Model as a means of initiating that change, within an integrated studies context. Finally, I suggest a number of related issues for further research.

description: For a general class of linear collisional kinetic models in the torus, including in particular the linearized Boltzmann equation for hard spheres, the linearized Landau equation with hard and moderately soft potentials and the semi-classical linearized fermionic and bosonic relaxation models, we prove explicit coercivity estimates on the associated integro-differential operator for some modified Sobolev norms. We deduce existence of classical solutions near equilibrium for the full non-linear models associated, with explicit regularity bounds, and we obtain explicit estimates on the rate of exponential convergence towards equilibrium in this perturbative setting. The proof are based on a linear energy method which combines the coercivity property of the collision operator in the velocity space with transport effects, in order to deduce coercivity estimates in the whole phase space.

description: We predict the redshift of the first observable (i.e., in our past light cone) Gamma Ray Burst (GRB) and calculate the GRB-rate redshift distribution of the Population III stars at very early times (z=20-60). Using the last 2 years of data from Swift we place an upper limit on the efficiency (η_{GRB}) of GRB production per solar mass from the first generation of stars. We find that the first observable GRB is most likely to have formed at redshift 60. The observed rate of extremely high redshift GRBs (XRGs) is a subset of a group of 15 long GRBs per year, with no associated redshift and no optical afterglow counterparts, detected by Swift. Taking this maximal rate we get that η_{GRB}<1.1~10^{-4} GRBs per solar mass in stars. A more realistic evaluation, e.g., taking a subgroup of 5% of the total sample of Swift gives an upper limit of η_{GRB}<3.2~10^{-5} GRBs per solar mass.

Post-Newtonian $γ$-like parameters and the gravitational slip in scalar-tensor and $f(R)$ theories

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We review the fundamentals and highlight the differences between some commonly used definitions for the PPN gamma parameter ($γ$) and the gravitational slip ($η$). Here we stress the usefulness of a gamma-like parameter used by Berry and Gair ($γ_{\scriptscriptstyle Σ}$) that parametrizes the bending of light and the Shapiro time delay in situations in which the standard $γ$ cannot be promptly used. First we apply our considerations to two well known cases, but for which some conflicting results can be found: massive Brans-Dicke gravity and $f(R)$ gravity (both the metric and the Palatini versions). Although the slip parameter is always well defined, it has in general no direct relation to either light deflection or the Shapiro time delay, hence care should be taken on imposing the PPN $γ$ bounds on the slip. We stress that, for any system with a well posed Newtonian limit, Palatini $f(R)$ theories always have $γ= 1$; while metric $f(R)$ theories can only have two values: either 1 or 1/2. The extension towards Horndeski gravity shows no qualitative surprises, and $γ_{\scriptscriptstyle Σ}$ is a constant in this context (only assuming that the Horndeski potentials can be approximated by analytical functions). This implies that a precise study on the bending of light for different impact parameters can in principle be used to rule out the complete Horndeski action as an action for gravity. Also, we comment on the consequences for $γ$ inferences at external galaxies.

description: With a resolution of 3 keV, the two lowest 0- states in 208Pb are identified by measurements of the reaction 207Pb(d, p) with the Muenchen Q3D magnetic spectrograph in a region where the average level spacing is 6 keV. Precise relative spectroscopic factors are determined. Matrix elements of the residual interaction among one-particle one-hole configurations in a two-level scheme are derived for the two lowest 0- states in 208Pb. The off-diagonal mixing strength is determined as 105 +-10(experimental) +-40(systematic) keV. Measurements of the reaction 208Pb(p,p') via isobaric analog resonances in 209Bi support the structure information obtained.

description: Using gravitational wave observations to search for deviations from general relativity in the strong-gravity regime has become an important research direction. Chern Simons (CS) gravity is one of the most frequently studied parity-violating models of strong gravity. It is known that the Kerr black-hole is not a solution for CS gravity. At the same time, the only rotating solution available in the literature for dynamical CS (dCS) gravity is the slow-rotating case most accurately known to quadratic order in spin. In this work, for the slow-rotating case (accurate to first order in spin), we derive the linear perturbation equations governing the metric and the dCS field accurate to linear order in spin and quadratic order in the CS coupling parameter ($α$) and obtain the quasi-normal mode (QNM) frequencies. After confirming the recent results of Wagle et al. (2021), we find an additional contribution to the eigenfrequency correction at the leading perturbative order of $α^2$. Unlike Wagle et al., we also find corrections to frequencies in the polar sector. We compute these extra corrections by evaluating the expectation values of the perturbative potential on unperturbed QNM wavefunctions along a contour deformed into the complex-$r$ plane. For $α=0.1 M^2$, we obtain the ratio of the imaginary parts of the dCS correction to the GR correction in the first QNM frequency (in the polar sector) to be $0.263$ implying significant change. For the $(2,2)-$mode, the dCS corrections make the imaginary part of the first QNM of the fundamental mode less negative, thereby decreasing the decay rate. Our results, along with future gravitational wave observations, can be used to test for dCS gravity and further constrain the CS coupling parameters. [abridged]

description: The aim of this research is twofold: Firstly, to model and solve a complex nurse scheduling problem with an integer programming formulation and evolutionary algorithms. Secondly, to detail a novel statistical method of comparing and hence building better scheduling algorithms by identifying successful algorithm modifications. The comparison method captures the results of algorithms in a single figure that can then be compared using traditional statistical techniques. Thus, the proposed method of comparing algorithms is an objective procedure designed to assist in the process of improving an algorithm. This is achieved even when some results are non-numeric or missing due to infeasibility. The final algorithm outperforms all previous evolutionary algorithms, which relied on human expertise for modification.

description: Στην παρούσα εργασία μελετάται το έργο του αυτοκράτορα Ιουλιανού με τίτλο Κατά Γαλιλαίων Λόγος. Η μελέτη αποτελείται από μια εισαγωγή όπου αναφέρονται κάποια βασικά στοιχεία για το συγγραφέα, το έργο του και το ιστορικό πλαίσιο και από τρία κύρια μέρη περιεχόμενο των οποίων αποτελούν κάποιες ερμηνευτικές παρατηρήσεις για το ύφος, τη γλώσσα και τις πηγές του κειμένου αντίστοιχα. Στο πρώτο μέρος γίνεται λόγος αφενός για το λογοτεχνικό είδος, στο οποίο μπορεί να ενταχθεί το συγκεκριμένο κείμενο· αφετέρου παρατίθενται κάποιες παρατηρήσεις σχετικά με τα υφολογικά χαρακτηριστικά του λόγου. Tο δεύτερο μέρος πραγματεύεται τη γλώσσα του κειμένου. Ακόμη, επιχειρείται μια σύγκριση των γλωσσικών στοιχείων του έργου με άλλα κείμενα της εποχής. Το τελευταίο μέρος είναι αφιερωμένο στο σχολιασμό των πηγών ενός συγκεκριμένου αποσπάσματος του Κατά Γαλιλαίων και στην παρουσίαση κάποιων στοιχείων της νεοπλατωνικής φιλοσοφίας αλλά και κάποιων ιδιαίτερων φιλοσοφικών όρων που εντοπίζονται στο έργο. Η μελέτη του Κατά Γαλιλαίων λόγου έδειξε ότι, παρά την αποσπασματική μορφή του, προσφέρει σημαντικό υλικό για την ανασύνθεση πτυχών της ζωής και του τρόπου σκέψης του συγγραφέα του. Ακόμη, μέσω του συγκεκριμένου κειμένου παρέχεται η δυνατότητα να γίνουν κάποιες παρατηρήσεις σχετικά με τον τρόπο αφομοίωσης από τους λόγιους αυτής της περιόδου νέων γλωσσικών στοιχείων που προκύπτουν από την απλοποίηση της αρχαΐζουσας γλώσσας, με την επίδραση χριστιανικών κειμένων και του προφορικού λόγου.
description: Τhis dissertation examines the work of Emperor Julian “Against the Galileans”. The study consists of an introduction that provides details on the author, his work, and the historical background, as well as three main parts, which discuss the style, the language, and the sources of the work respectively. The first part analyses the literary genre of this particular work· moreover, the text’s stylistic features are also examined. The language of the work is analyzed in the second part. In addition, a linguistic comparison is being held among the Julianic treatise and other writings of the same historical period. The last part refers to the sources of a text’s passage· furthermore, it examines Neoplatonic aspects as well as some philosophical terms found in the work. The study the “Against the Galileans” oration shows that, despite its fragmentary form, the text offers significant material for the reconstruction of aspects in the life and thought of Julian. Moreover, this text makes it possible to offer some remarks on the absorption by learned authors of this age of new linguistic features, which come from the simplification of the archaizing language, under the influence of Christian texts and speaking language.

description: Using Chandra and HST archival data, we have studied the individual Spectral Energy Distribution (SED) of 11 quasars. All UV spectra show a spectral break around 1100A. 5 X-ray spectra show the presence of a ``soft excess'' and 7 spectra showed an intrinsic absorption. We found that for most quasars a simple extrapolation of the far-UV powerlaw into the X-ray domain generally lies below the X-ray data and that the big blue bump and the soft X-ray excess do not share a common physical origin. We explore the issue of whether the observed SED might be dust absorbed in the far and near-UV. We fit the UV break, assuming a powerlaw that is absorbed by cubic nanodiamond dust grains. We then explore the possibility of a universal SED (with a unique spectral index) by including further absorption from SMC-like extinction. Using this approach, satisfactory fits to the spectra can be obtained. The hydrogen column densities required by either nanodiamonds or amorphous dust models are all consistent, except for one object, with the columns deduced by our X-ray analysis, provided that the C depletion is ~0.6. Because dust absorption implies a flux recovery in the extreme UV (<700A), our modeling opens the possibility that the intrinsic quasar SED is much harder and more luminous in the extreme UV than inferred from the near-UV data, as required by photoionization models of the broad emission line region. We conclude that the intrinsic UV SED must undergo a sharp turn-over before the X-ray domain.

description: Most existing personalization systems promote items that match a user's previous choices or those that are popular among similar users. This results in recommendations that are highly similar to the ones users are already exposed to, resulting in their isolation inside familiar but insulated information silos. In this context, we develop a novel recommendation framework with a goal of improving information diversity using a modified random walk exploration of the user-item graph. We focus on the problem of political content recommendation, while addressing a general problem applicable to personalization tasks in other social and information networks. For recommending political content on social networks, we first propose a new model to estimate the ideological positions for both users and the content they share, which is able to recover ideological positions with high accuracy. Based on these estimated positions, we generate diversified personalized recommendations using our new random-walk based recommendation algorithm. With experimental evaluations on large datasets of Twitter discussions, we show that our method based on \emph{random walks with erasure} is able to generate more ideologically diverse recommendations. Our approach does not depend on the availability of labels regarding the bias of users or content producers. With experiments on open benchmark datasets from other social and information networks, we also demonstrate the effectiveness of our method in recommending diverse long-tail items.

Industry sponsored student projects : in search of conditions of responsiveness between technological education and industry to address the increase in the rate of technological change
Creators: name: Wilmink, Ernst Willem
Publisher: name: University of British Columbia

description: The increasing rate of technological change is forcing educational institutions to adapt in its ways and means of curriculum development to remain in a viable position to prepare job ready graduates. In order to accomplish this task, the literature points out that a closer association with business and industry is required for educational institutions to respond to the technological changes as they occur in rapid succession. This problem was addressed in the School of Engineering Technology at the British Columbia Institute of Technology by introducing cash awards for students producing exemplary industry sponsored student projects in their graduating term. These projects were based on requests from industry with the intent to solve realworld problems. Students in more than 30 specialized fields of technology carried out these applied research projects to produce a tangible product of value to industry. This innovation was examined over three years (1990-93) to study the results of a closer association with the continuous advancement of technology in industry. The conditions for the required response to the needs of industry as a result were found in an increase in industry sponsored student projects, direct involvement of faculty in technological change, and the opportunity of direct input from industry to curriculum change. As such, a functional relationship was established to allow for curriculum to respond to technological change on an ongoing basis.

description: We study the momentum and frequency dependence of the dynamical spin susceptibility in the superconducting state of bilayer cuprate superconductors. We show that there exists a resonance mode in the odd as well as the even channel of the spin susceptibility, with the even mode being located at higher energies than the odd mode. We demonstrate that this energy splitting between the two modes arises not only from a difference in the interaction, but also from a difference in the free-fermion susceptibilities of the even and odd channels. Moreover, we show that the even resonance mode disperses downwards at deviations from ${\bf Q}=(π,π)$. In addition, we demonstrate that there exists a second branch of the even resonance, similar to the recently observed second branch (the $Q^*$-mode) of the odd resonance. Finally, we identify the origin of the qualitatively different doping dependence of the even and odd resonance. Our results suggest further experimental test that may finally resolve the long-standing question regarding the origin of the resonance peak.

description: For a separable Hamiltonian, there are two fundamental, time-symmetric, second-order velocity-Verlet (VV) and position-Verlet (PV) symplectic integrators. Similarly, there are two VV and PV version of exact energy conserving algorithms for solving magnetic field trajectories. For a constant magnetic field, both algorithms can be further modified so that their trajectories are exactly on the gyro-circle. The magnetic PV integrator then becomes the well known Boris solver, while VV yields a second, previously unknown, Boris-type algorithm. Remarkably, the required on-orbit modification is a reparametrization of the time step, reminiscent of the Ge-Marsden theorem.

Ion dynamics and the magnetorotational instability in weakly-ionized discs

description: The magnetorotational instability (MRI) of a weakly ionized, differentially rotating, magnetized plasma disk is investigated in the multi-fluid framework. The disk is threaded by a uniform vertical magnetic field and charge is carried by electrons and ions only. The inclusion of ion dynamics causes significant modification to the conductivity tensor in a weakly ionized disk. The parallel, Pedersen and Hall component of conductivity tensor become time dependent quantities resulting in the AC and DC part of the conductivity. The conductivity may change sign leading to the significant modification of the parameter window in which MRI may operate. The effect of ambipolar and Hall diffusion on the linear growth of the MRI is examined in the presence of time dependent conductivity tensor. We find that the growth rate in ambipolar regime can become somewhat larger than the rotational frequency, especially when the departure from ideal MHD is significant. Further, the instability operates on large scale lengths. This has important implication for the angular momentum transport in the disk.
