description: We discuss several issues important for experimentally observing Efimov physics in ultracold quantum gases. By numerically solving the three-boson Schrödinger equation over a broad range of scattering lengths and energies, and by including model potentials with multiple bound states, we address the complications of relating experimental observations to available analytic expressions. These more realistic potentials introduce features that can mask the predicted Efimov physics at small scattering lengths. They also allow us to verify that positive and negative scattering lengths are universally connected only across a pole, not across a zero. Additionally, we show that the spacing between Efimov features for the relatively small scattering lengths accessible experimentally fail to precisely follow the geometric progression expected for Efimov physics. Finally, we emphasize the importance of the short-range three-body physics in determining the position of Efimov features and show that theoretically reproducing two-body physics is not generally sufficient to predict three-body properties quantitatively.

description: Gravitational self-interactions are assumed to be determined by the covariant derivative acting on the Riemann-Christoffel field strength. Once imposed on a metric theory, this Yang-Mills gauge constraint extends the equality of gravitational mass and inertial mass to compact bodies with non-negligible gravitational binding energy. Applied to generalized Brans-Dicke theories, it singles out one tensor theory and one scalar theory for gravity but also suggests a way to implement a minimal violation of the strong equivalence principle.

Publisher: name: Zenodo
Year: 2023

description: the purpose of the article is to review the main methodological approaches and methods in modern music pedagogy (on the example of some foreign countries). The tasks of the article are appropriate and consist of the analysis of scientific literature on the research topic, as well as summarizing the approaches and practices of piano teaching in foreign countries in the conditions of departure from the traditional education system. The methodology of the article is based on a systematic approach and includes a group of general scientific methods (analysis, synthesis, deduction, induction), as well as a group of special methods: structural analysis of scientific literature on the research topic; elements of comparative analysis as well as descriptive analysis. It also concludes that the dominant methods of teaching piano in modern foreign countries (apart from the traditional method) are the integrated interdisciplinary approach and the cultural analysis of music.

description: We determine the polarized gluon distribution Δg(x) by a global analysis using current DIS and π^0 asymmetry data. The π^0 data from RHIC-Spin experiments provide a strong constraint on Δg(x), so that its uncertainty is reduced. However, a sign problem appears in the analysis using π^0 data, which means that positive and negative distributions are allowed for Δg(x). These two types of solutions are discussed.

Non-Perturbative Treatment of Charge and Spin Fluctuations in the Two-Dimensional Extended Hubbard Model: Extended Two-Particle Self-Consistent Approach

description: We study the spin and charge fluctuations of the extended Hubbard model (EHM) with on-site interaction U and first neighbor interaction V on the two-dimensional square lattice in the weak to intermediate coupling regime. We propose an extension of the two-particle self-consistent (ETPSC) approximation that includes the effect of functional derivatives of the pair correlation functions on irreducible spin and charge vertices. These functional derivatives were ignored in our previous work. We evaluate them assuming particle-hole symmetry. The resulting theory satisfies conservations laws and the Mermin-Wagner theorem. Our current results are in much better agreement with benchmark Quantum Monte-Carlo (QMC) results. As a function of U and V, we can determine the crossover temperatures towards renormalized classical regimes where either spin or charge fluctuations dominate. The dominant wave vector is self-determined by the approach.

description: Electrochemistry experiments have established that the capacitance of electrode-electrolyte interfaces is much larger for good metals such as gold and platinum than for carbon-based materials. Despite the development of elaborate electrode interaction potentials, to date molecular dynamics simulations were not able to capture this effect. Here we show that changing the width of the Gaussian charge distribution used to represent the atomic charges in gold is an effective way to tune its metallicity. Larger Gaussian widths lead to a capacitance of aqueous solutions (pure water and 1 molar NaCl) in good agreement with recent ab initio molecular dynamics results. For pure water, the increase in the capacitance is not accompanied with structural changes, while in the presence of salt the Na$^+$ cations tend to adsorb significantly on the surface. For a strongly metallic gold electrode, these ions can even form inner sphere complexes on hollow sites of the surface.

Legitimation of distance education: a social history of the Open Learning Institute of British Columbia 1978-1988
Creators: name: Moran, Louise
Publisher: name: University of British Columbia
Year: 2008

description: As Canadian higher education expanded from the 1950s, new institutions sought institutional legitimacy, meaning credibility and prestige in relation to educational peers and the state. Three dimensions to institutional legitimacy were identified: hierarchies of institutions, curricula and pedagogies; horizontal status within institutional sectors and fields of knowledge; and external legitimacy in relation to the state. New distance education institutions have found institutional legitimacy unusually problematic because of widespread skepticism about an educational form in which teacher and learner are separated in time and/or space. Distance educators typically balance industrial organizational forms using modern communications technologies, with attention to individual learners and accessibility. The study examined how a new, publicly-funded, distance education institution acquires legitimacy. The British Columbia government established the Open Learning Institute in 1978, over extensive opposition, with an unusual mandate to teach programs from degree level to adult basic education at a distance. OLI never fitted easily into either university or college sector. Ambiguity persisted over its roles as credential-provider and service agency, but OLI quickly proved its popularity with students. Its leaders adopted existing norms and standards, especially those of the universities, while insisting on college characteristics of openness and accessibility. Government Restraint policies in the 1980s materially affected OLI’s curriculum and pedagogies, and contributed to continuing debates over OLI’s role as provincial coordinator of distance education.

The Citation Impact of Digital Preprint Archives for Solar Physics Papers

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Papers that are posted to a digital preprint archive are typically cited twice as often as papers that are not posted. This has been demonstrated for papers published in a wide variety of journals, and in many different subfields of astronomy. Most astronomers now use the arXiv.org server (astro-ph) to distribute preprints, but the solar physics community has an independent archive hosted at Montana State University. For several samples of solar physics papers published in 2003, I quantify the boost in citation rates for preprints posted to each of these servers. I show that papers on the MSU archive typically have citation rates 1.7 times higher than the average of similar papers that are not posted as preprints, while those posted to astro-ph get 2.6 times the average. A comparable boost is found for papers published in conference proceedings, suggesting that the higher citation rates are not the result of self-selection of above-average papers.

description: We autonomously direct a small quadcopter package delivery Uncrewed Aerial Vehicle (UAV) or "drone" to take off, fly a specified route, and land for a total of 209 flights while varying a set of operational parameters. The vehicle was equipped with onboard sensors, including GPS, IMU, voltage and current sensors, and an ultrasonic anemometer, to collect high-resolution data on the inertial states, wind speed, and power consumption. Operational parameters, such as commanded ground speed, payload, and cruise altitude, are varied for each flight. This large data set has a total flight time of 10 hours and 45 minutes and was collected from April to October of 2019 covering a total distance of approximately 65 kilometers. The data collected were validated by comparing flights with similar operational parameters. We believe these data will be of great interest to the research and industrial communities, who can use the data to improve UAV designs, safety, and energy efficiency, as well as advance the physical understanding of in-flight operations for package delivery drones.

description: Recent direct $H(z)$ data indicate that the parameter $H(z)$ may wiggle with respect to $z$. On the other hand the luminosity distance data of supernovae flatten the wiggles of $H(z)$ because of integration effect. It is expected that the fitting results can be very different in a model permitting a wiggling $H(z)$ because the data of supernovae is highly degenerated to such a model. As an example the natural phantom dark energy is investigated in this paper. The dynamical property of this model is studied. The model is fitted by the direct $H(z)$ data set and the SNLS data set, respectively. And the results are quite different, as expected. The quantum stability of this model is also shortly discussed. We find it is a viable model if we treat it as an effective theory truncated by an upperbound.

description: As hashing becomes an increasingly appealing technique for large-scale image retrieval, multi-label hashing is also attracting more attention for the ability to exploit multi-level semantic contents. In this paper, we propose a novel deep hashing method for scalable multi-label image search. Unlike existing approaches with conventional objectives such as contrast and triplet losses, we employ a rank list, rather than pairs or triplets, to provide sufficient global supervision information for all the samples. Specifically, a new rank-consistency objective is applied to align the similarity orders from two spaces, the original space and the hamming space. A powerful loss function is designed to penalize the samples whose semantic similarity and hamming distance are mismatched in two spaces. Besides, a multi-label softmax cross-entropy loss is presented to enhance the discriminative power with a concise formulation of the derivative function. In order to manipulate the neighborhood structure of the samples with different labels, we design a multi-label clustering loss to cluster the hashing vectors of the samples with the same labels by reducing the distances between the samples and their multiple corresponding class centers. The state-of-the-art experimental results achieved on three public multi-label datasets, MIRFLICKR-25K, IAPRTC12 and NUS-WIDE, demonstrate the effectiveness of the proposed method.
Resonant switching using spin valves

description: Using micromagnetics we demonstrate that the r.f. field produced by a spin valve can be used to reverse the magnetization in a magnetic nanoparticle. The r.f. field is generated using a current that specifically excites a uniform spin wave in the spin valve. This current is swept such that the chirped-frequency generated by the valve matches the angular dependent resonant frequency of the anisotropy-dominated magnetic nanoparticle, as a result of which the magnetization reversal occurs. The switching is fast, requires currents similar to those used in recent experiments with spin valves, and is stable with respect to small perturbations. This phenomenon can potentially be employed in magnetic information storage devices or recently discussed magnetic computing schemes.

description: Large area van der Waals (vdW) thin films are assembled materials consisting of a network of randomly stacked nanosheets. The multi-scale structure and the two-dimensional nature of the building block mean that interfaces naturally play a crucial role in the charge transport of such thin films. While single or few stacked nanosheets (i.e. vdW heterostructures) have been the subject of intensive works, little is known about how charges travel through multilayered, more disordered networks. Here we report a comprehensive study of a prototypical system given by networks of randomly stacked reduced graphene oxide 2D nanosheets, whose chemical and geometrical properties can be controlled independently, permitting to explore percolated networks ranging from a single nanosheet to some billions with room temperature resistivity spanning from 10-5 to 10-1 ohm m. We systematically observe a clear transition between two different regimes at a critical temperature T*: Efros-Shklovskii variable range hopping (ESVRH) below T* and power law (PL) behavior above. Firstly, we demonstrate that the two regimes are strongly correlated with each other, both depending on the charge localization length xi, calculated by ES-VRH model, which corresponds to the characteristic size of overlapping sp2 domains belonging to different nanosheets. Thus, we propose a microscopic model describing the charge transport as a geometrical phase transition, given by the metal-insulator transition associated with the percolation of quasi-1D nanofillers with length xi, showing that the charge transport behavior of the networks is valid for all geometries and defects of the nanosheets, ultimately suggesting a generalized description on vdW and disordered thin films.

Using gauged linear sigma model renormalization group flows and toric geometry techniques, we see a cascade-like phase structure containing decays to lower order conifold-like singularities, including in particular the supersymmetric conifold and the $Y^{pq}$ spaces. This structure is consistent with the Type II GSO projection obtained previously for these singularities. Transitions between the various phases of these geometries include flips and flops.

Taking Judging and Judges Seriously: Facts, Framework and Function in Australian Constitutional Law

description: The key actors in the legal profession — judges, legal practitioners and the academy — each have roles to play in influencing and shaping the development of Australian constitutional law. This article addresses the importance of those key actors taking their own roles, and the roles of each other, seriously. It does so by examining three core themes — or threads — running through the fabric of Australian constitutional law: facts, framework and the judicial function. That examination reveals the importance of judges taking the role of judging as seriously as they do in shaping Australian constitutional law, but also the importance of practitioners and the academy understanding the judicial role, as well as their own roles, in helping to shape Australian constitutional law. In the end, judges, legal practitioners and academics travel the same road. Each brings unique contributions to the unceasing development and shaping of the mosaic which is Australian constitutional law.

description: We use a single dipole approximation to analyze the behavior of anisotropy-dominated magnetic nanoparticles subjected to an external r.f. field. We identify the steady state oscillations and analyze their stability. We also analyze the case when the external r.f. field has a time-dependent frequency which insures the most effective switching of the magnetization.
Collective bargaining in British Columbia's community colleges

description: This study examines collective bargaining in 14 unionized community colleges in British Columbia. It provides a broad overview of bargaining in the colleges and insights into the tensions commonly associated with collective bargaining. The study combines qualitative data and quantitative data through the use of interviews, contractual analysis and two questionnaires. One survey examined the opinions of board members, senior administrators and faculty leaders on various aspects of collective bargaining. The latter included the competitive characteristics of distributive bargaining, governance, the scope of the collective agreements and a number of proposed modifications aimed at improving bargaining in the colleges. The study is significant as it fills a void in the research related to the above issues in British Columbia's colleges. The literature review encompassed a wide range of research. This included material related to the evolution of collective bargaining in higher education; factors that influence opinions of bargaining; constructive conflict, destructive conflict and dysfunctional competition; conflict resolution techniques associated with bargaining; and integrative bargaining. The study revealed a competitive collective bargaining climate in the colleges, characterized by such factors as a lack of trust and respect, inexperienced faculty negotiators, contractual constraints and a lack of bargaining priorities. The competitive climate was aggravated by a number of external factors (government policies); internal factors (the management style of a president); the composition of the faculty associations (combined vocational and academic faculty associations); and personal factors (age and political preferences). In terms of governance issues, the scope of the collective agreements and their political orientation, the board members and the senior administrators are essentially from the same population. The faculty leaders come from a different population. The respondents favour modifications that would enhance communications, training, and equal access to information, as well as the resolution of labour matters at the local level rather than at the provincial level. Distributive bargaining will likely remain the cornerstone of negotiations in British Columbia's colleges. Although it does not have to be as competitive as it is, the distributive model appears to be best suited to the resolution of Level I issues, e.g. salaries, benefits. Given the collegial traditions of higher education, the varying professional needs of the faculty, the issue of management rights and the intrinsic values of the parties involved, a more collaborative model of bargaining is necessary to accommodate Level II issues. The latter include faculty participation in college governance, peer evaluation, and the selection of other faculty. The study contributed to the research literature and produced a number of recommendations for practice.

description: Three dimensional field configuration has been simulated for a simple wire chamber consisting of one anode wire stretched along the axis of a grounded square cathode tube by solving numerically the boundary integral equation of the first kind. A closed form expression of potential due to charge distributed over flat rectangular surface has been invoked in the solver using Green's function formalism leading to a nearly exact computation of electrostatic field. The solver has been employed to study the effect of several geometrical attributes such as the aspect ratio ($λ= \frac{l}{d}$, defined as the ratio of the length $l$ of the tube to its width $d$) and the wire modeling on the field configuration. Detailed calculation has revealed that the field values deviate from the analytic estimates significantly when the $λ$ is reduced to 2 or below. The solver has demonstrated the effect of wire modeling on the accuracy of the estimated near-field values in the amplification region. The thin wire results can be reproduced by the polygon model incorporating a modest number of surfaces ($\geq 32$) in the calculation with an accuracy of more than 99%. The smoothness in the three dimensional field calculation in comparison to fluctuations produced by other methods has been observed.

description: Van der Waals heterostructures composed of multiple few layer crystals allow the engineering of novel materials with predefined properties. As an example, coupling graphene weakly to materials with large spin orbit coupling (SOC) allows to engineer a sizeable SOC in graphene via proximity effects. The strength of the proximity effect depends on the overlap of the atomic orbitals, therefore, changing the interlayer distance via hydrostatic pressure can be utilized to enhance the interlayer coupling between the layers. In this work, we report measurements on a graphene/WSe$_2$ heterostructure exposed to increasing hydrostatic pressure. A clear transition from weak localization to weak anti-localization is visible as the pressure increases, demonstrating the increase of induced SOC in graphene.
Aspects of modeling III-V semiconductor devices
Creators: name: Zhou, Haosheng
Publisher: name: University of British Columbia

description: This thesis is concerned with novel modeling approaches to three GaAs-based devices, namely: the heterojunction bipolar transistor (HBT), the metal-semiconductor field-effect transistor (MESFET) and the modulation-doped field-effect transistor (MODFET). In GaAs-based HBTs, the transit time of carriers across the collector-base space-charge region plays an important role in determining the performance of these devices at high frequency. In this thesis, a novel phenomenological approach is developed to modeling transport phenomena in GaAs-based HBTs. The model takes the dynamics of intervalley electron transfer into account so that effects such as velocity overshoot can be studied. The results from this computationally-effective phenomenological model are in good agreement with those from the time-consuming Monte Carlo approach. This suggests that the phenomenological model could be a useful tool for HBT design. The model is extended to treat the practically-important case of operation at very high collector currents. It is revealed, perhaps for the first time, that the holes in a n-p-n device play a very significant role in the decline of the device’s speed performance at high current levels. A one-dimensional model for MESFETs is developed in which the characterizing system of ordinary differential equations is analyzed by the phase portrait method. The model yields two criteria for the formation of a stationary dipole domain in MESFETs. One of these criteria pertains to the product of the doping density and the gate length, and produces a length-dependent value which is different from the constant value appropriate to travelling domains and which has been widely-used in the past for stationary domain formation. The new criterion should prove useful in analysing the dynamic performance of MESFETs. A new method for obtaining the electron surface charge density in the potential well of MODFETs is presented. The surface charge density is needed in calculations of the I—V and C—V characteristics of the device. The new method uses the WKB method to solve Schrödinger’s equation for the bound states, and introduces a modified effective density of states function to solve Poisson’s equation for the potential profile. The method yields excellent agreement with the much more computationally—intensive full quantum approach to the solution.

description: In this work, we develop a combined convolutional neural networks (CNNs) and finite element method (FEM) to examine the effective thermal properties of composite phase change materials (CPCMs) consisting of paraffin and copper foam. In this approach, first the CPCM microstructures are modeled using FEM and next the image dataset with corresponding thermal properties is created. The image dataset is subsequently used to train and test the CNN performance, which is then compared with the performance of a popular network architecture for image classification tasks. The predicted thermal properties are employed to define the properties of the CPCM material of a battery pack. The heat generation and electrochemical response of a Li-ion cell during the charging/discharging is simulated by applying Newman battery model. Thermal management is achieved by the latent heat of paraffin, with copper foam for enhancing the thermal conductivity. The multiscale model is finally developed using FEM to investigate the effectiveness of the thermal management of the battery pack. In these models the thermal properties estimated by the FEM and the CNN are employed to define the CPCM materials properties of a battery pack. Our results confirm that the model developed on the basis of a CNN can evaluate the effectiveness of the battery packs thermal management system with an excellent accuracy in comparison with the original FEM models.
Taking Judging and Judges Seriously: Facts, Framework and Function in Australian Constitutional Law

description: The key actors in the legal profession — judges, legal practitioners and the academy — each have roles to play in influencing and shaping the development of Australian constitutional law. This article addresses the importance of those key actors taking their own roles, and the roles of each other, seriously. It does so by examining three core themes — or threads — running through the fabric of Australian constitutional law: facts, framework and the judicial function. That examination reveals the importance of judges taking the role of judging as seriously as they do in shaping Australian constitutional law, but also the importance of practitioners and the academy understanding the judicial role, as well as their own roles, in helping to shape Australian constitutional law. In the end, judges, legal practitioners and academics travel the same road. Each brings unique contributions to the unceasing development and shaping of the mosaic which is Australian constitutional law.

description: We present results of N-body simulations aimed at understanding the dynamics of young stars near the Galactic center. Specifically, we model the inspiral of a cluster core containing an intermediate mass black hole and $N \sim 50$ cluster stars in the gravitational potential of a supermassive black hole. We first study the elliptic three-body problem to isolate issues of tidal stripping and subsequent scattering, followed by full N-body simulations to treat the internal dynamics consistently. We find that our simulations reproduce several dynamical features of the observed population. These include the observed inner edge of the claimed clockwise disk, as well as the thickness of said disk. We find that high density clumps, such as that claimed for IRS13E, also result generically from our simulations. However, not all features of the observations are reproduced. In particular, the surface density profile of the simulated disk scales as $Σ\propto r^{-0.75}$, which is considerably shallower than that observed. Further, at no point is any significant counter-rotating population formed.
