description: Many quantum condensed matter systems are strongly correlated and strongly interacting fermionic systems, which cannot be treated perturbatively. However, physics which emerges in the low-energy corner does not depend on the complicated details of the system and is relatively simple. It is determined by the nodes in the fermionic spectrum, which are protected by topology in momentum space (in some cases, in combination with the vacuum symmetry). Close to the nodes the behavior of the system becomes universal; and the universality classes are determined by the toplogical invariants in momentum space. When one changes the parameters of the system, the transitions are expected to occur between the vacua with the same symmetry but which belong to different universality classes. Different types of quantum phase transitions governed by topology in momentum space are discussed in this Chapter. They involve Fermi surfaces, Fermi points, Fermi lines, and also the topological transitions between the fully gapped states. The consideration based on the momentum space topology of the Green's function is general and is applicable to the vacua of relativistic quantum fields. This is illustrated by the possible quantum phase transition governed by topology of nodes in the spectrum of elementary particles of Standard Model.

description: In this work, we study the topological properties and magnon Hall effect of a three-dimensional ferromagnet in the ABC stacking honeycomb lattice, motivated by the recent inelastic neutron scattering study of CrI$_3$. We show that the magnon band structure and Chern numbers of the magnon branches are significantly affected by the interlayer coupling $J_c$, which moreover has a qualitatively different effect in the ABC stacking compared to the AA stacking adopted by other authors. The nontrivial Chern number of the lowest magnon band is stabilized by the next-nearest-neighbour Dzyaloshinsky-Moriya interaction in each honeycomb layer, resulting in the hopping term similar to that in the electronic Haldane model for graphene. However, we also find several gapless Weyl points, separating the non-equivalent Chern insulating phases, tuned by the ratio of the interlayer coupling $J_c$ and the third-neighbour Heisenberg interaction $J_3$. We further show that the topological character of magnon bands results in non-zero thermal Hall conductivity, whose sign and magnitude depend on $J_c$ and the intra-layer couplings. Since the interlayer coupling strength $J_c$ can be easily tuned by applying pressure to the quasi-2D material such as CrI$_3$, this provides a potential route to tuning the magnon thermal Hall effect in an experiment.

description: Renormalization group techniques are widely used in modern physics to describe the low energy relevant aspects of systems involving a large number of degrees of freedom. Those techniques are thus expected to be a powerful tool to address open issues in data analysis when data sets are very larges. Signal detection and recognition for covariance matrix having a nearly continuous spectra is currently one of these opened issues. First investigations in this direction has been proposed in [Journal of Statistical Physics, 167, Issue 3-4, pp 462-475, (2017)] and [arXiv:2002.10574], from an analogy between coarse-graining and principal component analysis (PCA), regarding separation of sampling noise modes as a UV cut-off for small eigenvalues of the covariance matrix. The field theoretical framework proposed in this paper is a synthesis of these complementary point of views, aiming to be a general and operational framework, both for theoretical investigations and for experimental detection. Our investigations focus on signal detection, and exhibit experimental evidences in favor of a connection between symmetry breaking and the existence of an intrinsic detection threshold.

description: Axion helioscopes like the planned International Axion Observatory (IAXO) search for evidence of axions and axion-like particles (ALPs) from the Sun. A strong magnetic field is used to convert ALPs into photons via the generic ALP-photon coupling. To observe the resulting photons, X-ray detectors with low background and high efficiency are necessary. In addition, good energy resolution and low energy threshold would allow for investigating the ALP properties by studying the X-ray spectrum after its discovery. We propose to use low temperature metallic magnetic calorimeters (MMCs). Here we present the first detector system based on MMCs developed for IAXO and discuss the results of the characterization. The detector consists of a two-dimensional 64-pixel array covering an active area of 16 mm$^2$ with a fill factor of 93 %. We achieve an average energy resolution of 6.1 eV FWHM allowing for energy thresholds below 100 eV. This detector is the first step towards a larger 1 cm$^2$ array matching the IAXO X-ray optics. We determine the background rate for an unshielded detector system in the energy range between 1 keV and 10 keV to be $3.2(1) \times 10^{-4}$ keV$^{-1}$ cm$^{-2}$ s$^{-1}$ from events acquired over 30 days. In the future, active and passive shields will significantly reduce the background induced by cosmic muons and natural radioactivity. Our results demonstrate that MMCs are a promising technology for helioscopes to discover and study ALPs.

description: Electron temperatures, densities, ionic and elemental abundances of helium, nitrogen, oxygen, argon, sulfur and neon were derived for a sample of bulge planetary nebulae, representative of its intermediate mass population. Using these results as constraints, a model for the chemical evolution of the galactic bulge was developed. The results indicate that the best fit is achieved using a double-infall model, where the first one is a fast collapse of primordial gas and the second is slower and enriched by material ejected by the bulge itself during the first episode.

description: Mobile energy resources (MERs) have been shown to boost DS resilience effectively in recent years. In this paper, we propose a novel idea, the separable mobile energy storage system (SMESS), as an attempt to further extend the flexibility of MER applications. "Separable" denotes that the carrier and the energy storage modules are treated as independent parts, which allows the carrier to carry multiple modules and scatter them independently throughout the DS. The constraints for scheduling SMESSs involving carriers and modules are derived based upon the interactive behavior among them and the DS. In addition, the fuel delivery issue of feeding mobile emergency generators (MEGs), which was usually bypassed in previous studies involving the scheduling of MEGs, is also considered and modeled. SMESSs, MEGs, and fuel tankers (FTs) are then jointly routed and scheduled, along with the dynamic DS reconfiguration, for DS service restoration by integrating them in a mixed-integer linear programming (MILP) model. Finally, the test is conducted on a modified IEEE 33-node test system, and results verify the effectiveness of the model in boosting DS resilience.

We first apply the asymptotic iteration method to recover the known exact solutions for the pure Coulomb case. For a screened-Coulomb potential and for a Coulomb plus linear potential with linear scalar confinement, the method is used to obtain accurate approximate solutions for both eigenvalues and wave functions.

Zero-shot Relation Classification from Side Information

description: We propose a zero-shot learning relation classification (ZSLRC) framework that improves on state-of-the-art by its ability to recognize novel relations that were not present in training data. The zero-shot learning approach mimics the way humans learn and recognize new concepts with no prior knowledge. To achieve this, ZSLRC uses advanced prototypical networks that are modified to utilize weighted side (auxiliary) information. ZSLRC's side information is built from keywords, hypernyms of name entities, and labels and their synonyms. ZSLRC also includes an automatic hypernym extraction framework that acquires hypernyms of various name entities directly from the web. ZSLRC improves on state-of-the-art few-shot learning relation classification methods that rely on labeled training data and is therefore applicable more widely even in real-world scenarios where some relations have no corresponding labeled examples for training. We present results using extensive experiments on two public datasets (NYT and FewRel) and show that ZSLRC significantly outperforms state-of-the-art methods on supervised learning, few-shot learning, and zero-shot learning tasks. Our experimental results also demonstrate the effectiveness and robustness of our proposed model.

Enclosures in Scotland : evidence from the old statistical account
Creators: name: Douglas, Catherine
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study is to assess the impact of enclosures on total factor productivity in the northeast of Scotland at the end of the eighteenth century. Rent, wage and price data for 49 parishes has been gathered from John Sinclair's twenty volume Statistical Account(1791-1798). Each of the parishes is characterised by the state of enclosure, land classification, market access, and whether or not lime, marl and turnip husbandry were in use. Economic analysis and statistical methods are used to assess the relationship between these variables, rent differentials and total factor productivity. The main findings of this study indicate that there were efficiency gains from enclosure and that those gains accrued to both landlords and to farm workers. These results have important distributional implications, and point to the different experience of rural workers in England and Scotland at this time.
Energy dependence of directed flow over a wide range of pseudorapidity in Au+Au collisions at RHIC

description: We report on measurements of directed flow as a function of pseudorapidity in Au+Au collisions at energies of $\sqrt{s_{_{NN}}} =$ 19.6, 62.4, 130 and 200 GeV as measured by the PHOBOS detector at the Relativistic Heavy Ion Collider (RHIC). These results are particularly valuable because of the extensive, continuous pseudorapidity coverage of the PHOBOS detector. There is no significant indication of structure near midrapidity and the data surprisingly exhibit extended longitudinal scaling similar to that seen for elliptic flow and charged particle pseudorapidity density.

description: This position paper describes the experimental behavior design of the adaptable humanoid social robot Pepper in four different roles in class. In 2018 and 2019, we held English classes in seven Finnish elementary schools with a twofold mission. Our aim was both to showcase these four different social roles in an English class of 5th graders and to discuss future robot-assisted education and collaborative learning with the children. As a design strategy, we developed pedagogical robot applications and adopted the content to the curriculum of the 5 th grade and to cultural phenomena that Finnish children aged 10-12 were well familiar with. However, although one thoroughly designs for a meaningful experience of-and interaction with-a robot, other factors are at play that affect the perception of the robot and interaction with it. All things considered, we conclude that co-created robot applications, corresponding to the curriculum and contemporary youth culture that the children interact with co-present in class, offer an interesting and accessible opportunity for children to reflect on the use and design of socially assistive robots.

description: The problem of data exchange between multiple nodes with storage and communication capabilities models several current multi-user communication problems like Coded Caching, Data Shuffling, Coded Computing, etc. The goal in such problems is to design communication schemes which accomplish the desired data exchange between the nodes with the optimal (minimum) amount of communication load. In this work, we present a converse to such a general data exchange problem. The expression of the converse depends only on the number of bits to be moved between different subsets of nodes, and does not assume anything further specific about the parameters in the problem. Specific problem formulations, such as those in Coded Caching, Coded Data Shuffling, Coded Distributed Computing, can be seen as instances of this generic data exchange problem. Applying our generic converse, we are able to efficiently recover known important converses in these formulations. Further, for a generic coded caching problem with heterogeneous cache sizes at the clients with or without a central server, we obtain a new general converse, which subsumes some existing results. Finally we relate a `centralized' version of our bound to the known generalized independence number bound in index coding, and discuss our bound's tightness in this context.

Perfect quantum state transfer with randomly coupled quantum chains

Year: 2005
Subjects: subject: Quantum Physics (quant-ph)

description: We suggest a scheme that allows arbitrarily perfect state transfer even in the presence of random fluctuations in the couplings of a quantum chain. The scheme performs well for both spatially correlated and uncorrelated fluctuations if they are relatively weak (say 5%). Furthermore, we show that given a quite arbitrary pair of quantum chains, one can check whether it is capable of perfect transfer by only local operations at the ends of the chains, and the system in the middle being a "black box". We argue that unless some specific symmetries are present in the system, it will be capable of perfect transfer when used with dual-rail encoding. Therefore our scheme puts minimal demand not only on the control of the chains when using them, but also on the design when building them.

description: We unravel the polaronic properties of impurities immersed in a correlated trapped one-dimensional (1D) Bose-Bose mixture. This setup allows for the impurities to couple either attractively or repulsively to a specific host, thus offering a highly flexible platform for steering the emergent polaronic properties. Specifically, the polaronic residue peak and strength of induced interactions can be controlled by varying the coupling of the impurities to the individual bosonic components. In particular, it is possible to maintain the quasiparticle character for larger interaction strengths as compared to the case of impurities immersed in a single bosonic species. We explicate a hierarchy of the polaron binding energies in terms of the impurity-medium interactions, thereby elucidating the identification of the polaronic resonances in recent experimental radiofrequency schemes. For strong attractive impurity-medium couplings bipolaron formation is captured. Our findings pave the way for continuously changing the quasiparticle character, under the impact of trap effects, while exposing the role of correlations in triple mixture settings.

description: Only seven radio-quiet isolated neutron stars (INSs) emitting thermal X rays are known, a sample that has yet to definitively address such fundamental issues as the equation of state of degenerate neutron matter. We describe a selection algorithm based on a cross-correlation of the ROSAT All-Sky Survey (RASS) and the Sloan Digital Sky Survey (SDSS) that identifies X-ray error circles devoid of plausible optical counterparts to the SDSS g~22 magnitudes limit. We quantitatively characterize these error circles as optically blank; they may host INSs or other similarly exotic X-ray sources such as radio-quiet BL Lacs, obscured AGN, etc. Our search is an order of magnitude more selective than previous searches for optically blank RASS error circles, and excludes the 99.9% of error circles that contain more common X-ray-emitting subclasses. We find 11 candidates, nine of which are new. While our search is designed to find the best INS candidates and not to produce a complete list of INSs in the RASS, it is reassuring that our number of candidates is consistent with predictions from INS population models. Further X-ray observations will obtain pinpoint positions and determine whether these sources are entirely optically blank at g~22, supporting the presence of likely isolated neutron stars and perhaps enabling detailed follow-up studies of neutron star physics.

description: Tomato, being a tropical species, is sensitive to temperatures below 10°C, thus limiting its growth to warmer regions and greenhouses. Understanding the cold response pathways in tomato will help improve its climate resiliency through breeding and biotechnology. Reportedly, plant genes undergo alternative splicing (AS) in response to various environmental stresses, however, the scope and dynamics of alternative splicing events in response to cold are unknown in tomato. To fill this knowledge gap, a fine-scale time-series cold (4°C) experiment was performed followed by RNA-sequencing of shoot and root tissues in tomato. Computational analysis revealed that various AS events occur within the first 20 minutes of temperature reduction and later on. Many AS genes were common between shoots and roots, however, the majority of the changes were organ-specific. Circadian rhythm and photosynthesis were the most significant among the various impacted biological processes, highlighting their importance in cold stress response. This study will help us gain insights into cold response pathways of tomato and other commercially important, closely related Solanaceae species.

Parental post-operative medication administration: investigating predictors of attitude
Creators: name: Pillai, Rebecca R.E.
Publisher: name: University of British Columbia
Year: 2009

description: The Theory of Planned Behaviour (TPB) was used as a theoretical framework to elucidate the roles of beliefs and attitudes in the parental management of paediatric post-surgical pain. In essence, the TPB states that beliefs predict attitude, attitude predicts intention and intention predicts behaviour. Over the past 25 years, researchers have used this model to examine the extent to which attitudes (mediated by intention) predict behaviour. The evidence indicates that parents with negative attitudes will tend to undermedicate their children. However, that is not enough. To improve the in-home management of children's post-operative pain, researchers and clinicians need to understand why some parents have negative attitudes towards pain medications. This thesis set out to determine if various factors, aside from beliefs, could reliably predict a parent's attitude toward administering pain medication to their child. Archival data from 236 parents who had a child undergoing day surgery at British Columbia's Children's Hospital were used. As anticipated by the TPB, it was found that the belief-based measure was a significant predictor of attitude. But contrary to expectations, variables relating to the parents' personal experiences with surgery were stronger predictors of attitude. These findings will aid in bridging the gap between the theory and practice of paediatric pain management.

description: Introduction
 Pharmacists play an important role in identifying prescribing errors, but their ability in correctly detecting errors is not well understood. We investigated the ability of pharmacists in detecting prescribing errors, and whether feedback improved their ability to do so. Methodology
 A quasi-experimental study was conducted in a proportionate random sample of 18 public specialist hospitals, district hospitals, and health clinics in Perak. The study population was pharmacists involved in dispensing medications at the paediatric outpatient setting. A pharmacist was appointed at each site to review prescriptions of patients aged 12 years and below. Data were collected during the first (baseline), third, and fifth (end of study) months of the study. Personalised feedback was provided to pharmacists following data collection at baseline and fifth month of the study. The primary endpoint was the difference in the percentage of prescriptions with errors missed by pharmacists between baseline and end of study. Results
 A total of 6,076 prescriptions were reviewed. At baseline, 17.1% prescriptions had errors, and pharmacists correctly detected 11.4%. At the end of the study, the percentage of prescriptions with error reduced to 10.4%, and pharmacists correctly detected 8.5%. Following provision of feedback, the ability of pharmacists to detect errors improved, as the percentage of prescriptions with errors missed was 5.7% at baseline and 1.9% at end of study (difference 3.8%, 95% CI: 2.5%, 5.1%). Discussion/Conclusion
 Pharmacists must not be assumed as a complete safety net to detect and prevent prescribing errors. Continuous monitoring is essential to ensure patient safety.

description: Introduction
 Stethee™, a new wireless digital stethoscope, has not been evaluated alongside the conventional stethoscope. We therefore compared Stethee™ to Littmann® for the auscultation of heart sounds. Methodology
 In this randomised, open-label, two-period crossover, non-inferiority trial, non-specialist doctors with no more than 6 years of working experience post-house officer training, were randomly assigned (1:1) to Stethee™ first group or Littmann® first group to auscultate a set of 10 simulated heart sounds. Randomisation was stratified by type of centre. Doctors were also asked about their preference for stethoscopes in terms of audio clarity, ease of use, and diagnostic accuracy. The primary non-inferiority endpoint was the percentage of correctly identified heart sounds, with a non-inferiority margin of 10%. Differences were estimated using a generalised linear mixed effects model, adjusted for sequence and period effects. Secondary endpoints included the percentage of correctly identified cardiac diagnoses, and user preference. Results
 A total of 207 doctors were assessed for eligibility, of whom 105 were randomised and analysed. The percentage of correctly identified heart sounds was 31.1% for Stethee™ and 33.4% for Littmann® (difference 2.2%, 90% CI -0.7, 5.0). The proportion of correctly identified cardiac diagnoses was 24.8% for Stethee™ and 28.2% for Littmann® (difference 3.2%, 90% CI 0.7, 5.7). Most doctors rated Stethee™ as having better audio quality than Littmann® (83.8%), and would provide a more accurate diagnosis (84.8%), but felt that Stethee™ was less user-friendly than Littmann® (61.0%). Discussion/Conclusion
 Stethee™ is non-inferior to Littmann® in the identification of simulated heart sounds and cardiac diagnoses.

description: We revisit the astrophysical constraints on a generic light CP-even scalar particle $S$, mixing with the Standard Model (SM) Higgs boson, from observed luminosities of the Sun, red giants, white dwarfs and horizontal-branch stars. The production of $S$ in the stellar core is dominated by the electron-nuclei bremsstrahlung process $e + N \to e + N + S$. With the $S$ decay and reabsorption processes taken into consideration, we find that the stellar luminosity limits exclude a broad range of parameter space in the $S$ mass-mixing plane, with the scalar mass up to 350 keV and the mixing angle ranging from $7.0\times10^{-18}$ to $3.4\times10^{-3}$. We also apply the stellar limits to a real-singlet scalar extension of the SM, where we can relate the mixing angle to the parameters in the scalar potential. In both the generic scalar case and the real-singlet extension, we show that the stellar limits preclude the scalar interpretation of the recently observed XENON1T excess in terms of the $S$ particles emitted from the Sun.

description: This report describes an integrated agro-ecological modeling system that was developed to assess the potential economic and soil erosion impacts of different agricultural policies for the Canadian prairie provinces of Alberta, Saskatchewan, and Manitoba. The system was constructed by linking erosion metamodels (response functions), based on multiple simulations of the USDA Erosion Productivity Impact Calculator (EPIIC), with a modified version of Agriculture Canada's Canadian Regional Agriculture Model (CRAM) denoted as RS-CRAM (resource sensitive CRAM). A summary of both the environmental and agricultural decision (RS-CRAM) components are presented, including a description of the modifications and enhancements that were made to CRAM. Results of policy analyses are discussed for the following scenarios: (1) Gross Revenue Insurance Program (GRIIP), (2) sensitivity of GRIP results to different risk levels, (3) tillage practice sensitivity, and (4) industrial crops sensitivity. Future recommendations are also presented, emphasizing how the current system can be improved and the potential to include additional regions, environmental indicators, and other environmental models within the system.
Triangular Lattice Model of 2D Defect Melting

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We set up a harmonic lattice model for 2D defect melting which, in contrast to earlier simple-cubic models, lives on a triangular lattice. Integer-valued plastic defect gauge fields allow for the thermal generation of dislocations and disclinations. The model produces universal formulas for the melting temperature expressed in terms of the elastic constants, which are different from those derived for square lattices. They determine a Lindemann-like parameter for two-dimensional melting. In contrast to the square crystal which underwent a first-order melting transition, the triangular model melts in two steps. Our results are applied to the melting of Lennard-Jones and electron lattices.

description: We investigate the interplay between the electron-electron and the electron-phonon interaction in the Hubbard-Holstein model. We implement the flow-equation method to investigate within this model the effect of correlation on the electron-phonon effective coupling and, conversely, the effect of phonons in the effective electron-electron interaction. Using this technique we obtain analytical momentum-dependent expressions for the effective couplings and we study their behavior for different physical regimes. In agreement with other works on this subject, we find that the electron-electron attraction mediated by phonons in the presence of Hubbard repulsion is peaked at low transferred momenta. The role of the characteristic energies involved is also analyzed.

Dynamics of magnetic collective modes in the square and triangular lattice Mott insulators at finite temperature

description: We study the equilibrium dynamics of magnetic moments in the Mott insulating phase of the Hubbard model on the square and triangular lattice. We rewrite the Hubbard interaction in terms of an auxiliary vector field and use a recently developed Langevin scheme to study its dynamics. A thermal `noise', derivable approximately from the Keldysh formalism, allows us to study the effect of finite temperature. At strong coupling, $U \gg t$, where $U$ is the local repulsion and $t$ the nearest neighbour hopping, our results reproduce the well known dynamics of the nearest neighbour Heisenberg model with exchange $J \sim {\cal O}(t^2/U)$. These include crossover from weakly damped dispersive modes at temperature $T \ll J$ to strong damping at $T \sim {\cal O}(J)$, and diffusive dynamics at $T \gg J$. The crossover temperatures are naturally proportional to $J$. To highlight the progressive deviation from Heisenberg physics as $U/t$ reduces we compute an effective exchange scale $J_{eff}(U)$ from the low temperature spin wave velocity. We discover two features in the dynamical behaviour with decreasing $U/t$: (i)~the low temperature dispersion deviates from the Heisenberg result, as expected, due to longer range and multispin interactions, and (ii)~the crossovers between weak damping, strong damping, and diffusion take place at noticeably lower values of $T/J_{eff}$. We relate this to enhanced mode coupling, in particular to thermal amplitude fluctuations, at weaker $U/t$. A comparison of the square and triangular lattice reveals the additional effect of geometric frustration on damping.

Extrapolation of compactness on weighted spaces: Bilinear operators

description: In a previous paper, we obtained several "compact versions" of Rubio de Francia's weighted extrapolation theorem, which allowed us to extrapolate the compactness of linear operators from just one space to the full range of weighted Lebesgue spaces, where these operators are bounded. In this paper, we study the extrapolation of compactness for bilinear operators in terms of bilinear Muckenhoupt weights. As applications, we easily recover and improve earlier results on the weighted compactness of commutators of bilinear Calderón-Zygmund operators, bilinear fractional integrals and bilinear Fourier multipliers. More general versions of these results are recently due to Cao, Olivo and Yabuta (arXiv:2011.13191), whose approach depends on developing weighted versions of the Fréchet--Kolmogorov criterion of compactness, whereas we avoid this by relying on "softer" tools, which might have an independent interest in view of further extensions of the method.

description: This paper briefly describes the environmental component of an integrated modeling system that has been developed for simulating the movement of nutrients (nitrogen and phosphorus) from dairy waste disposal fields through the Upper North Bosque River Watershed (UNBRW) stream network in Erath and Hamilton Countries, Texas, as part of the "Livestock and the Environment: A National Pilot Project" (NPP). The environmental component consists of the Agricultural Policy/Environmental eXtender (APEX) model and the Soil Water Assessment Tool (SWAT). The APEX model is designed to simulate the edge-of-field nutrient runoff and leaching loadings from the application of solid and liquid manure on dairy waste disposal fields that are subsequently routed through the UNBRW stream system in SWAT to the watershed outlet near Hico, Texas. The basis for selecting APEX and SWAT, and the linkages between the two models, are emphasized within the context of the UNBRW modeling system configuration. A brief overview of the watershed characteristics and the in-stream water quality monitoring system installed on the UNBRW stream network is also presented. This monitoring system provides a key data set that has been used to calibrate the environmental modeling component for current conditions in the watershed.
