description: The structural origin of Cu+ ions conductivity in Cu6PS5I single crystals is described in terms of structural phase transitions studied by X-ray diffraction, polarizing microscope and calorimetric measurements. Below the phase transition at Tc=(144-169) K Cu6PS5I belongs to monoclinic, ferroelastic phase, space group Cc. Above Tc crystal changes the symmetry to cubic superstructure, space group F-43c (a=19.528); finally at 274K disordering of the Cu+ ions increases the symmetry to F-43m, (a=9.794). The phase transition at 274K coincides well with a strong anomaly in electrical conductivity observed in the Arrhenius plot. Diffusion paths for Cu+ ions are evidenced by means of the atomic displacement factors and split model. Influence of the copper stechiometry on the Tc is also discussed.

description: We show that starburst galaxies convert efficiently cosmic-rays into pions, which in turn decay into high-energy neutrinos and photons. The cumulative background of GeV neutrinos is 10^{-7}GeV/cm^2/s/sr. Its extrapolation to higher neutrino energies depends on the energy spectrum of the injected cosmic-rays and is proportional to E^{-0.15+-0.1} up to E~0.3PeV and possibly higher neutrino energies. This flux, which constitutes a lower limit to the high energy extra-Galactic neutrino flux, is likely to be detectable by forthcoming km-scale neutrino telescopes.

description: The binary fraction of a stellar population can have pronounced effects on its properties, and in particular the number counts of different massive star types, and the relative subtype rates of the supernovae which end their lives. Here we use binary population synthesis models with a binary fraction that varies with initial mass to test the effects on resolved stellar populations and supernovae, and ask whether these can constrain the poorly-known binary fraction in different mass and metallicity regimes. We show that Wolf-Rayet star subtype ratios are valuable binary diagnostics, but require large samples to distinguish by models. Uncertainties in which stellar models would be spectroscopically classified as Wolf-Rayet stars are explored. The ratio of thermonuclear, stripped envelope and other core-collapse supernovae may prove a more accessible test and upcoming surveys will be sufficient to constrain both the high mass and low mass binary fraction in the z < 1 galaxy population.

The 3D Form Analysis of Regional Architecture Using Deep Learning: A Case Study of Wood Churches from the Carpathian Mountains

Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: subject: 120199 Architecture not elsewhere classified
subject: FOS: Civil engineering

description: Recent research into 3-D architectural and urban form analysis using deep learning (DL) methods has shown potential to extract and identify intrinsic features from large collections of building data and draw novel insights into how our built environment is configured and interrelated. In order to explore these new capabilities, this thesis offers a detailed case study of a critical engagement with building data and DL techniques for the purposes of architectural-historical form analysis. For a case study, it documents the creation of a custom dataset of 3-D meshes of 313 wooden churches located within and near the Carpathian Mountain regions of Ukraine using photographic data and 3-D reconstruction techniques. Though the subject of ongoing scholarly interest, the complex regional style variations of these churches has made it difficult to establish clear stylistic rules that govern both their differences and similarities. As a result, this lack of consensus has led to conflicting findings and ongoing contention amongst researchers. Given this challenge, this thesis attempts to demonstrate how recent statistic based rather than traditional heuristic approaches might provide an alternate way to obtain new insight into this issue. For example, by offering a way to search for and identify both complex and nuanced form relationships and patterns among hundreds of churches at once within a single diagram. This includes detecting where stylistic overlap occurs, identifying groups of hybrid-styled churches, uncovering endemic micro styles, and revealing broad form patterns that illustrate how architectural features gradually morph across hundreds of buildings. The thesis thus offers a path for DL-based form analysis techniques to be put in conversation with traditional architectural studies, helping identify strengths and weaknesses, as well as opportunities for hybrid and cross-methodological architectural-historical analyses. Indirectly, this thesis also demonstrates an alternate method of architectural documentation through a combination of 3D building reconstruction from sparse imagery and architectural style encoding using DL-methods. Considering the threat to Ukrainian culture given the current war with Russia, digitally preserving both the individual churches themselves through 3D reconstruction and the rules that define their styles through DL-methods, has the potential to document and protect this important and distinctive part of Ukrainian architectural folk heritage.

description: Our experiments show that for two or more pieces of a wire, of different lengths in general, combined in parallel and connected to a dc source, the current ratio evolves towards unity as the combination is cooled to the superconducting transition temperature Tc, and remains pinned at that value below it. This re-distribution of the total current towards equipartition without external fine tuning is a surprise. It can be physically understood in terms of a mechanism that involves the flux-flow resistance associated with the transport current in a wire of type-II superconducting material. It is the fact that the flux-flow resistance increases with current that drives the current division towards equipartition.
description: Revised version of J.Phys. Condens.Matter; vol. 18(2006) L143-L147 14 pages including 3 figures; provided an explanation in terms of the physical mechanism of flux flow induced resistance that is proportional to the impressed current. We are adding a simple, physically robust derivation of our equipartition without taking resort to the minimum dissipation principle

description: Weak measurement in tandem with real-time feedback control is a new route toward engineering novel non-equilibrium quantum matter. Here we develop a theoretical toolbox for quantum feedback control of multicomponent Bose-Einstein condensates (BECs) using backaction-limited weak measurements in conjunction with spatially resolved feedback. Feedback in the form of a single-particle potential can introduce effective interactions that enter into the stochastic equation governing system dynamics. The effective interactions are tunable and can be made analogous to Feshbach resonances -- spin-independent and spin-dependent -- but without changing atomic scattering parameters. Feedback cooling prevents runaway heating due to measurement backaction and we present an analytical model to explain its effectiveness. We showcase our toolbox by studying a two-component BEC using a stochastic mean-field theory, where feedback induces a phase transition between easy-axis ferromagnet and spin-disordered paramagnet phases. We present the steady-state phase diagram as a function of intrinsic and effective spin-dependent interaction strengths. Our result demonstrates that closed-loop quantum control of Bose-Einstein condensates is a powerful new tool for quantum engineering in cold-atom systems.

The Impact of Institutional Power on Higher Degree Research Supervision: Implications for the Quality of Doctoral Outcomes

description: This paper examines the impact of power in the supervision process as experienced by the PhD students, the institutional influence upon this, and implications for the quality of the doctoral outcome. This research paper is based on findings of a larger, recently completed PhD with the aim to develop a participant-driven theory of the lived experience of being a PhD student. This was done by analyzing the reported experiences of 23 PhD students in various disciplines and stages of their PhD studying at Australian Universities over a period of 12 months. Participants were given the freedom to choose and prioritize the experiences to report on and how they reported on them. Core to the supervision findings was the issue of power and how institutional influences distort the power relationship between the supervisor and the supervisee. Adopting French and Raven’s (1959) Bases of Social Power, the institutional power sources that play on the PhD candidate are enacted through ‘actors’ in the institutional process including the supervisor are presented. The findings support the need for institutions to systematically review their practices to meet their duty of care to their PhD students to provide high quality HDR supervision and improve doctoral outcomes. This research addresses a gap in contemporary supervision literature by addressing the impact of institutional power and institutional practices on the academic supervisor and how these play out in the utilization of power on and over the PhD student and the doctoral outcome.
Policing beyond VAWIR policy : criminal harassment, pro-arrest and the practice of discretionary power
Creators: name: Pacey, Katrina E.
Publisher: name: University of British Columbia
Year: 2009

description: Relevant policy dictates that only particular interventions are to be employed when police are handling incidents involving violence against women in relationships. The objective of this study is to examine the way police officers describe their practice when investigating cases involving women victims who are criminally harassed by intimate or formerly intimate partners. This study inquires into the influence of this policy as well as the influence of other situational and organizational factors in the specific area of policing criminal harassment. In-depth interviews took place with 20 Vancouver police officers and qualitative analysis was employed. The data shows that the officers in this sample see themselves as highly discretionary in their practice and that their decision-making is influenced by the way in which they construct a number of situational and organizational factors. It was found that the vast majority of police in this sample constructed the victim, the crime of criminal harassment, and the criminal justice system in such a way so as to justify not following the protocols outlined in the Violence Against Women in Relationships Policy. Furthermore, it is argued that the attitudes which inform their discretionary practice can be seen as reflective of the attitudes embedded in police subculture as well as in dominant society. The implications of this research point to a need for further exposure and, perhaps, parameters around police practice so as to limit the negative effects of the patriarchal police subculture on women victims of violence.

description: Emergent behavior at complex oxide interfaces has driven much of the research in the oxide thin film community for the past twenty years. Interfaces have been engineered for potential applications in spintronics, topological quantum computing, and high-speed electronics in cases where the bulk materials would not exhibit the desired properties. Advances in thin film growth have made the synthesis of these interfaces possible, while surface characterization tools such as X-ray photoelectron spectroscopy have been critical to understanding surface and interfacial phenomena in these materials. In this review we discuss the leading research in the oxide field over the past 5-10 years with a focus on connecting the key results to the X-ray photoelectron spectroscopy studies that enabled them. We describe how in situ integration of synthesis and spectroscopy can be used to improve the film growth process and to perform immediate experiments on specifically tailored interfacial heterostructures. These studies can include determination of interfacial intermixing, valence band alignment, and interfacial charge transfer. We also show how advances in synchrotron-based spectroscopy techniques have answered questions that cannot be addressed in a lab-based system. By further tying together synthesis and spectroscopy through in situ techniques, we conclude by discussing future opportunities in the field through the careful design of thin film heterostructures that are optimized for X-ray studies.

description: The thermal Sunyaev-Zel'dovich (tSZ) and the kinematic Sunyaev-Zel'dovich (kSZ) effects trace the distribution of electron pressure and momentum in the hot Universe. These observables depend on rich multi-scale physics, thus, simulated maps should ideally be based on calculations that capture baryonic feedback effects such as cooling, star formation, and other complex processes. In this paper, we train deep convolutional neural networks with a U-Net architecture to map from the three-dimensional distribution of dark matter to electron density, momentum and pressure at ~ 100 kpc resolution. These networks are trained on a combination of the TNG300 volume and a set of cluster zoom-in simulations from the IllustrisTNG project. The neural nets are able to reproduce the power spectrum, one-point probability distribution function, bispectrum, and cross-correlation coefficients of the simulations more accurately than the state-of-the-art semi-analytical models. Our approach offers a route to capture the richness of a full cosmological hydrodynamical simulation of galaxy formation with the speed of an analytical calculation.

description: We introduce and discuss a simple Hamiltonian dynamical system, interpretable as a 3-body problem in the complex plane and providing the prototype of a mechanism explaining the transition from regular to irregular motions as travel on Riemann surfaces. The interest of this phenomenology -- illustrating the onset in a deterministic context of irregular motions -- is underlined by its generality, suggesting its eventual relevance to understand natural phenomena and experimental investigations. Here only some of our main findings are reported, without detailing their proofs: a more complete presentation will be published elsewhere.

Structure of Passive Circumstellar Disks: Beyond the Two-Temperature Approximation

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Structure and spectral energy distributions (SEDs) of externally irradiated circumstellar disks are often computed on the basis of the two-temperature model of Chiang & Goldreich. We refine these calculations by using a more realistic temperature profile which is continuous at all optical depths and thus goes beyond the two-temperature model. It is based on the approximate solution of the radiation transfer in the disk obtained from the frequency-integrated moment equations in the Eddington approximation. We come up with a simple procedure (``constant g_z approximation'') for treating the vertical structure of the disk in regions where its optical depth to stellar radiation is high. This allows us to obtain expressions for the vertical profiles of density and pressure at every point in the disk and to determine the shape of its surface. Armed with these analytical results we calculate the full radial structure of the disk and demonstrate that it favorably agrees with the results of direct numerical calculations. We also describe a simple and efficient way of the SED calculation based on our adopted temperature profile. Resulting spectra provide very good match (especially at short wavelengths) to the results of more detailed (but also more time-consuming) SED calculations solving the full frequency- and angle-dependent radiation transfer within the disk.

description: We apply a simple linearization, well known in solid state physics, to approximate the evolution at early times of cosmological N-body simulations of gravity. In the limit that the initial perturbations, applied to an infinite perfect lattice, are at wavelengths much greater than the lattice spacing $l$ the evolution is exactly that of a pressureless self-gravitating fluid treated in the analagous (Lagrangian) linearization, with the Zeldovich approximation as a sub-class of asymptotic solutions. Our less restricted approximation allows one to trace the evolution of the discrete distribution until the time when particles approach one another (i.e. ``shell crossing''). We calculate modifications of the fluid evolution, explicitly dependent on $l$ i.e. discreteness effects in the N body simulations. We note that these effects become increasingly important as the initial red-shift is increased at fixed $l$. The possible advantages of using a body centred cubic, rather than simple cubic, lattice are pointed out.

Structural studies of protein partnerships of the PNT domain of GABP[alpha]
Creators: name: MacIntosh, Scott Earl
Publisher: name: University of British Columbia
Year: 2009

description: Background: The Ets family of transcription factors is an established model system for studying the regulation of gene expression. In addition to the DNA-binding ETS domain, several Ets proteins contain a second region of conserved sequence, the Pointed (PNT) domain. Although the exact functions of this domain remain to be established, there is a mounting body of evidence that the PNT domain mediates interactions with partner transcription factors. However, a detailed structural study of PNT domain interactions has yet to be carried out. This information is essential for a complete understanding of the role of the PNT domain in the control of gene expression by the Ets transcription factors. Goals: Previous work in the McIntosh laboratory has focused on the PNT domain of GABPα. To continue studies on this domain, three main goals of this thesis work were formulated: i) Use of a yeast two-hybrid system to screen for protein, partners of the domain. ii) A detailed study of the domain to investigate the possibility of self-association. iii) A detailed study of the domain to investigate the possibility of a small molecule binding to the domain. Results and conclusions: A yeast two-hybrid screen was used in an attempt to identify proteins that interacted with the minimal PNT domain of GABPα. One potential interacting protein, PBP, was identified. However, attempts to demonstrate a direct interaction between the proteins in vitro were unsuccessful. The behaviour of a minimal GABPα PNT domain construct during purification suggested that this protein formed oligomers. However, no evidence of self-association of the protein was obtained using several different techniques. As a result, this is likely an artifact with no biological relevance. Resonances not assignable to any amino acid residues were present in the NMR spectra of the GABPα PNT domain, raising the possibility that a small molecule was binding to the domain. Using NMR and mass spectrometry, this molecule was tentatively identified as an N-acetyl hexosamine oligomer. However, NMR relaxation experiments and further purification of the protein failed to provide any evidence that this molecule was binding the PNT domain of GABPα with appreciable affinity.

description: There has been a significant increase in private sector participation (PSP) in the urban water supply and sanitation (WSS) sector in recent years. However, even with increased PSP, public authorities will still have to: ensure that the service providers do not use their market power to exploit customers; internalise public health and environmental externalities; provide mechanisms whereby water consumption is sustainable and is allocated efficiently between alternative uses; and, serve as a guarantor of a level of service provision which is consistent with a basic standard of living. While there is considerable literature addressing the first of these four issues, the latter three are less adequately addressed. Through a review of five case studies (Abidjan, Buenos Aires, Cordoba, Mexico City, and Manila), this paper provides an overview of the issues involved and some of the mechanisms available to the authorities responsible for the regulation of the sector.
The Economics of Fisheries Access Agreements: Perspectives on the EU-Senegal Case

description: Relations between coastal countries and fishing fleets from non-adjacent countries changed radically in the 1970s and early 1980s. This was primarily a consequence of the declaration of exclusive economic zones (EEZs) by many coastal states in the years leading up to the close of the negotiations of the United Nations Convention on the Law of the Sea (UNCLOS) in 1982. Most significantly, by recognizing the right of coastal states to determine how their waters were to be exploited, the UNCLOS provided a legal basis and economic motivation for the negotiation of access agreements between coastal states and distant water fishing fleets. This paper examines some of the economic issues which arise out of such agreements, particularly as they relate to relations between relatively poor coastal states and fishing fleets from richer non-adjacent countries. Using Senegal-EU agreements as a case study it examines the economics of the agreements from the perspective of the coastal country. Factors related to the characteristics of the distant water fleet (ie, relative discard rates, fleet infractions, changes in fleet efficiency, and the mobility of the fleet) and the characteristics of the coastal country (ie, public debt and discount rates, capital constraints, access to overseas markets, and national political considerations) are examined in order to cast light on the incentives for signing the agreements.

description: Environmental economics has an extensive literature on procedures for placing economic values on the environment. Most of these methodologies have been developed and refined in the context of developed countries, where high levels of disposable income allow for a high demand for environmental amenities and a willingness to pay for non-use values. This paper argues that the applicability of these methodologies may be limited in developing countries. A microeconomic model, designed to highlight the different roles of environmental goods and services in developed and developing counties, is presented. In developing countries the value of environmental amenities is relatively less important than the value of environmental resources in the production process. The use of the procedures to estimate the value of environmental services in production should be respected, promoted and refined, particularly in light of widespread market failure in developing countries.

description: The final chapter in the long-standing mystery of the gamma-ray bursts (GRBs) centres on the origin of the short-hard class, suspected on theoretical grounds to result from the coalescence of neutron star or black hole binary systems. Numerous searches for the afterglows of short-hard bursts have been made, galvanized by the revolution in our understanding of long-duration GRBs that followed the discovery in 1997 of their broadband (X-ray, optical, and radio) afterglow emission. Here we present the discovery of the X-ray afterglow of a short-hard burst whose accurate position allows us to unambiguously associate it with a star-forming galaxy at redshift z=0.160, and whose optical lightcurve definitively excludes a supernova association. Together with results from three other recent short-hard bursts, this suggests that short-hard bursts release much less energy than the long-duration GRBs. Models requiring young stellar populations, such as magnetars and collapsars, are ruled out, while coalescing degenerate binaries remain the most promising progenitor candidates.

description: In 1992, the Government of Mexico initiated a new national water law which decentralised water resources management and allowed the market transfer of water-use concessions between individual irrigators. These reforms were expected to improve water resources management through greater user participation in irrigation management, as well as to increase irrigators' incentives to improve water-use efficiency. At the time of its proposal the 1992 Federal Water Law was considered to the first step in the establishment of limited water markets. This paper addresses the opportunities and constraints to improved water resource use and allocation through the market incentives that result from transferable water-use permits. The paper reviews water allocation institutions in Mexico and provides case studies of water allocation and decision-making.

description: We present the drastic transformation of the X-ray properties of the active galactic nucleus 1ES 1927+654, following a changing-look event. After the optical/UV outburst the power-law component, produced in the X-ray corona, disappeared, and the spectrum of 1ES 1927+65 instead became dominated by a blackbody component ($kT\sim 80-120$ eV). This implies that the X-ray corona, ubiquitously found in AGN, was destroyed in the event. Our dense $\sim 450$ day long X-ray monitoring shows that the source is extremely variable in the X-ray band. On long time scales the source varies up to $\sim 4$ dex in $\sim 100$ days, while on short timescales up to $\sim2$ dex in $\sim 8$ hours. The luminosity of the source is found to first show a strong dip down to $\sim 10^{40}\rm\,erg\,s^{-1}$, and then a constant increase in luminosity to levels exceeding the pre-outburst level $\gtrsim $300 days after the optical event detection, rising up asymptotically to $\sim 2\times10^{44}\rm\,erg\,s^{-1}$. As the X-ray luminosity of the source increases, the X-ray corona is recreated, and a very steep power-law component ($Γ\simeq 3$) reappears, and dominates the emission for 0.3-2 keV luminosities $\gtrsim 10^{43.7}\rm\,erg\,s^{-1}$, $\sim 300$ days after the beginning of the event. We discuss possible origins of this event, and speculate that our observations could be explained by the interaction between the accretion flow and debris from a tidally disrupted star. Our results show that changing-look events can be associated with dramatic and rapid transformations of the innermost regions of accreting SMBHs.

description: We present conductance characteristics of point contact junctions realized between a normal Pt-Ir tip and YBa$_2$Cu$_3$O$_{7-x}$/La$_{0.7}$Ca$_{0.3}$MnO$_3$ (YBCO/LCMO) bilayers. The point contact characteristics show a zero bias conductance peak, as a consequence of the formation of Andreev bound states at the YBCO Fermi level. The temperature evolution of the spectra reveals a depressed zero bias peak and a reduced superconducting energy gap, both explainable in terms of spin polarization effects due to the LCMO layer.

description: Dwarf novae (DNe) and low mass X-ray binaries (LMXBs) show eruptions that are thought to be due to a thermal-viscous instability in their accretion disk. These eruptions provide constraints on angular momentum transport mechanisms. We explore the idea that angular momentum transport could be controlled by the dynamical evolution of the large scale magnetic field. We study the impact of different prescriptions for the magnetic field evolution on the dynamics of the disk. This is a first step in confronting the theory of magnetic field transport with observations. We develop a version of the disk instability model that evolves the density, the temperature and the large scale vertical magnetic flux together. We take into account the accretion driven by turbulence or by a magnetized outflow. To evolve the magnetic flux, we use a toy model with physically motivated prescriptions depending mainly on the local magnetization. We find that allowing magnetic flux to be advected inwards provides the best agreement with DNe lightcurves. This leads to a hybrid configuration with an inner magnetized disk, driven by angular momentum losses to an MHD outflow, sharply transiting to an outer weakly-magnetized turbulent disk, where the eruptions are triggered. The dynamical impact is equivalent to truncating a viscous disk so that it does not extend down to the compact object, with the truncation radius dependent on the magnetic flux and evolving as $\dot{M}^{-2/3}$. Models of DNe and LMXBs lightcurves typically require the outer, viscous disk to be truncated in order to match observations. There is no generic explanation for this truncation. We propose that it is a natural outcome of the presence of large-scale magnetic fields in both DNe and LMXBs, the magnetic flux accumulating towards the center to produce a magnetized disk with a fast accretion timescale.

description: Farmers' intentions about conversion to particularly animal-friendly stabling system (PAFS) are analyzed with a structural equation model. The Theory of Planned Behavior (ToPB, Ajzen 1985) is used as the theoretical basis of this study. Though ToPB is a well-defined theory, it is static rather than procedural and cannot model the individual decision-making as a process. Therefore, we first examine the general applicability of ToPB in an agricultural context and explain the variance in intentions of farmers to convert to PAFS. Second, we extend the ToPB to make it more procedural. For this purpose, research findings from the Diffusion Theory are included as part of the behavioral model. The empirical results indicate that the model has a good fit to the data. The effects of the additional variables "Goal" and "Communication" are highly significant. This illustrates the importance of forming personal goals in the behavior domain and that people act in a goal-directed, rational way. Moreover, it gives empirical evidence that communication through personal channels has a great impact on individual decision-making. Altogether, this study shows that the extended ToPB provides an appropriate approach to investigate individual decision-making processes in agriculture.

description: We conducted a global analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey - a prototype of the SPECULOOS transit search conducted with the TRAPPIST-South robotic telescope in Chile from 2011 to 2017 - to estimate the occurrence rate of close-in planets such as TRAPPIST-1b orbiting ultra-cool dwarfs. For this purpose, the photometric data of 40 nearby ultra-cool dwarfs were reanalysed in a self-consistent and fully automated manner starting from the raw images. The pipeline developed specifically for this task generates differential light curves, removes non-planetary photometric features and stellar variability, and searches for transits. It identifies the transits of TRAPPIST-1b and TRAPPIST-1c without any human intervention. To test the pipeline and the potential output of similar surveys, we injected planetary transits into the light curves on a star-by-star basis and tested whether the pipeline is able to detect them. The achieved photometric precision enables us to identify Earth-sized planets orbiting ultra-cool dwarfs as validated by the injection tests. Our planet-injection simulation further suggests a lower limit of 10 per cent on the occurrence rate of planets similar to TRAPPIST-1b with a radius between 1 and 1.3 $R_\oplus$ and the orbital period between 1.4 and 1.8 days.

description: We study the ground state properties of the Heisenberg spin-1/2 chain with ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor interactions using two approximate methods. One of them is the Jordan-Wigner mean-field theory and another approach based on the transformation of spin operators to bose-ones and on the variational treatment of bosonic Hamiltonian. Both approaches give close results for the ground state energy and the T=0 magnetization curve. It is shown that quantum fluctuations change the classical critical exponents in the vicinity of the transition point from the ferromagnetic to the singlet ground state. The magnetization process displays the different behavior in the regions near and far from the transition point. The relation of the obtained results to experimental magnetization curve in $Rb_{2}Cu_{2}Mo_{3}O_{12}$ is discussed.
