description: A class of exact solutions of Hele-Shaw flows without surface tension in a rotating cell is reported. We show that the interplay between injection and rotation modifies drastically the scenario of formation of finite-time cusp singularities. For a subclass of solutions, we show that, for any given initial condition, there exists a critical rotation rate above which cusp formation is prevented. We also find an exact sufficient condition to avoid cusps simultaneously for all initial conditions. This condition admits a simple interpretation related to the linear stability problem.

description: Performing astronomical data analysis using only personal computers is becoming impractical for the very large data sets produced nowadays. As analysis is not a task that can be automatized to its full extent, the idea of moving processing where the data is located means also moving the whole scientific process towards the archives and data centers. Using Jupyter Notebooks as a remote service is a recent trend in data analysis that aims to deal with this problem, but harnessing the infrastructure to serve the astronomer without increasing the complexity of the service is a challenge. In this paper we present the architecture and features of JOVIAL, a Cloud service where astronomers can safely use Jupyter notebooks over a personal space designed for high-performance processing under the high-availability principle. We show that features existing only in specific packages can be adapted to run in the notebooks, and that algorithms can be adapted to run across the data center without necessarily redesigning them.

description: The discovery of 3:2 quasi-periodic oscillations (QPOs) in the ultraluminous X-ray source NGC 1313 X-1 suggests it harbors an intermediate-mass black hole (IMBH). We test this numerically by modelling the 3:2 QPOs and the associated X-ray spectrum based on the epicyclic resonance model and a disk-corona model with large-scale magnetic fields generated by the Cosmic Battery mechanism. The combined QPO-frequency and spectral fitting indicates that the BH mass ranges from 2524M_sun to 6811M_sun confirming its IMBH nature, and the BH spin is probably higher than ~0.3.

description: We model the thermal dust emission from dust grains heated by synchrotron radiation and by particle collisions, under conditions appropriate for four different shocked and unshocked gas components of the Cassiopeia A (Cas A) supernova remnant (SNR). By fitting the resulting spectral energy distributions (SEDs) to the observed SNR dust fluxes, we determine the required mass of dust in each component. We find the observed SED can be reproduced by $\sim 0.6 \, {\rm M_\odot}$ of silicate grains, the majority of which is in the unshocked ejecta and heated by the synchrotron radiation field. Warmer dust, located in the X-ray emitting reverse shock and blastwave regions, contribute to the shorter wavelength infrared emission but make only a small fraction of the total dust mass. Carbon grains can at most make up $\sim 25 \%$ of the total dust mass. Combined with estimates for the gas masses, we obtain dust-to-gas mass ratios for each component, which suggest that the condensation efficiency in the ejecta is high, and that dust in the shocked ejecta clumps is well protected from destruction by sputtering in the reverse shock.

description: It is generally accepted that relativistic jet outflows power the nonthermal emission from active galactic nuclei (AGN). The composition of these jets -- leptonic versus hadronic -- is still under debate. We investigate the microphysical details of the conversion process of the kinetic energy in collimated relativistic pair outflows into radiation through interactions with the ambient interstellar medium. Viewed from the coordinate system comoving with the pair outflow, the interstellar protons and electrons represent a proton-electron beam propagating with relativistic speed in the pair plasma. We demonstrate that the beam excites both electrostatic and low-frequency magnetohydrodynamic Alfven-type waves via a two-stream instability in the pair background plasma, and we calculate the time evolution of the distribution functions of the beam particles and the generated plasma wave turbulence power spectra. For standard AGN jet outflow and environment parameters we show that the initial beam distributions of interstellar protons and electrons quickly relax to plateau-distributions in parallel momentum, transferring thereby one-half of the initial energy density of the beam particles to electric field fluctuations of the generated electrostatic turbulence. On considerably longer time scales, the plateaued interstellar electrons and protons will isotropise by their self-generated transverse turbulence and thus be picked-up in the outflow pair plasma. These longer time scales are also characteristic for the development of transverse hydromagnetic turbulence from the plateaued electrons and protons. This hydromagnetic turbulence upstream and downstream is crucial for diffusive shock acceleration to operate at external or internal shocks associated with pair outflows.

description: In this theoretical study, the problem of self-focusing of an X-ray intense laser beam in the thermal quantum plasma is studied. Using a relativistic fluid model and taking into account the hydrodynamic pressure of degenerate electrons in the zero temperature limit, the nonlinear momentum equation of electrons is solved by means of a perturbative method and the nonlinear current density of the relativistic degenerate electrons is obtained. Saving only the third-order nonlinearity of the laser beam amplitude, a nonlinear equation describing the interaction of laser beam with the quantum plasma is derived. It is shown that considering the nonlinearity of system through solving nonlinear equation of degenerate electron leads to the originally different wave equation in comparison with outcomes of the approach in which the permittivity of longitudinal waves of quantum plasma is problematically extended to the relativistic case. The evolution of laser beam spot size with Gaussian profile is considered and the effect of quantum terms on the self-focusing quality is studied. It is shown that considering quantum effects leads to the decrease in the self-focusing property and the effect of Bohm tunneling potential is more dominant than the degenerate electrons pressure term.

Can gravity appear due to polarization of instantons in the SO(4) gauge theory?

description: Conventional non-Abelian SO(4) gauge theory is able to describe gravity provided the gauge field possesses a specific polarized vacuum state. In this vacuum the instantons and anti-instantons have a preferred direction of orientation. Their orientation plays the role of the order parameter for the polarized phase of the gauge field. The interaction of a weak and smooth gauge field with the polarized vacuum is described by an effective long-range action which is identical to the Hilbert action of general relativity. In the classical limit this action results in the Einstein equations of general relativity. Gravitational waves appear as the mode describing propagation of the gauge field which strongly interacts with the oriented instantons. The Newton gravitational constant describes the density of the considered phase of the gauge field. The radius of the instantons under consideration is comparable with the Planck radius.

subject: Electrical engineering not elsewhere classified

description: Electrical smart meters (also known as advanced meters, or “type 4 meters”) present the potential for improved public safety outcomes through the collection of real-time big data, which could be used to remotely identify defects or abnormal operating conditions within the meter. Meter internal temperature could be a useful measure for this as it is simple to obtain. High internal temperatures are associated with range of issues within the meters and can damage electrical components over time, reducing the operating life of the unit.
There is currently a lack of research relating to smart meter operational temperature behaviour, and this is linked to a current lack of publicly available operational meter data. This practice based, exploratory research project aimed to answer the following research problem: “To improve the safety of smart meters through early prediction of fault conditions, what are the temperature related behaviours within a smart meter while operating normally, in a range of environmental and usage conditions?”
To achieve this, operational temperature data was analysed from 2478 in-service, operational smart meters over a nine-month period (from August 2019 to May 2020) to determine the proportion of meters which exceeded manufacturer operating limits. Additionally, each data point was linked by location, time and date to the closest available Bureau of Meteorology Weather station to compare internal meter temperature with ambient air temperature.
The research was able to identify the proportion of meters within the population which exceeded operational temperature limits. The research was also able to determine the difference in mean meter and air temperature at different times of the day as well as in cases where operational temperature limits were exceeded.

description: The high-precision astrometry from the second data release of the Gaia mission has made it possible to greatly improve the census of members of nearby clusters and associations. I have applied the Gaia data to the Taurus star-forming region, refining the sample of known members and identifying candidates for undiscovered members. The resulting samples of members and candidates provide the best constraints to date on the distribution of ages and the initial mass function (IMF) in Taurus. Several studies over the last 30 years have proposed the existence of a population of older stars (>=10 Myr) that is associated with the Taurus clouds. The data from Gaia demonstrate that such a population does not exist. Meanwhile, previous IMF estimates for small fields surrounding the Taurus aggregates have exhibited a surplus of K7-M0 stars (0.7-0.8 Msun) relative to star-forming clusters like IC 348 and the Orion Nebula Cluster. However, that difference disappears when the new census of the entire region is considered, which should be complete for spectral types earlier than M6-M7 at A_J<1. Thus, there is little variation in the stellar IMF across the 3-4 orders of magnitude in stellar density that are present in nearby star-forming regions. Finally, I note that the proper motions of two previously known members, KPNO 15 and 2MASS J04355209+2255039, indicate that they may have been ejected from the same location within the L1536 cloud ~7200 years ago.

For generalizing this method the author advocates the usefulness of the classical Riemann-Hecke approach, his adelic complexes together with his generalization of Krichever's correspondence. He analyzes dimension 1 types of functions and discusses properties of the lattice of commensurable classes of subspaces in the adelic space associated to a divisor on an algebraic surface.

description: Graph-based data models allow for flexible data representation. In particular, semantic data based on RDF and OWL fuels use cases ranging from general knowledge graphs to domain specific knowledge in various technological or scientific domains. The flexibility of such approaches, however, makes programming with semantic data tedious and error-prone. In particular the logics-based data descriptions employed by OWL are problematic for existing error-detecting techniques, such as type systems. In this paper, we present DOTSpa, an advanced integration of semantic data into programming. We embed description logics, the logical foundations of OWL, into the type checking process of a statically typed programming language and provide typed data access through an embedding of the query language SPARQL. In addition, we demonstrate a concrete implementation of the approach, by extending the Scala programming language. We qualitatively compare programs using our approach to equivalent programs using a state-of-the-art library, in terms of how both frameworks aid users in the handling of typical failure scenarios.

description: In GO/MoSe2 semiconductor heterostructure, we have demonstrated a subtle control on the doping dynamics by modulating interlayer coupling through the combination of strain-reducing relative rotation of the constituting layers and variation of ligand type and concentration. By first-principles calculations incorporating spin-orbital coupling, we have investigated the impact of variable interlayer coupling in introducing non-collinear magnetic behaviour in the heterostructure. The outcome of varying carrier type and their respective concentrations are investigated by static as well as time dependent density functional calculations, which indicates presence of optical anisotropy and time-dependent optical phenomena like exciton quenching and band-gap renormalization. Performance of such heterostructures as channel material in devices with top and edge metal contacts is analyzed. Our self-consistent quantum transport calculations have evinced that the nature of interface-induced variation in doping is extrapolated for devices only in the case of top contacts. The edge contact, although exhibits a better transmission, are inefficient for sensing the ligand-induced doping modulation introduced via vertical inter-layer charge transfer.

description: X-ray observations have shown that the chemical abundance in the starburst galaxy M82 is quite rich in Si and S compared with oxygen. Such an abundance pattern cannot be explained with any combination of conventional Type I and II supernova yields. Also the energy to heavy element mass ratio of the observed hot plasma is much higher than the value resulted from normal supernovae. We calculate explosive nucleosynthesis in core-collapse hypernovae and show that the abundance pattern and the large ratio between the energy and the heavy element mass can be explained with the hypernova nucleosynthesis. Such hypernova explosions are expected to occur for stars more massive than >~ 20-25 Msun, and likely dominating the starburst, because the age after the starburst in M82 is estimated to be as short as ~ 10^6 - 10^7 yr. We also investigate pair-instability supernovae (~ 150-300 Msun) and conclude that the energy to heavy element mass ratio in these supernovae is too small to explain the observation.

description: Even in the face of deteriorating and highly volatile demand, firms often invest in, rather than discard, aging technologies. In order to study this phenomenon, we model the firm's profit stream as a Brownian motion with negative drift. At each point in time, the firm can continue operations, or it can stop and exit the project. In addition, there is a one-time option to make an investment which boosts the project's profit rate. Using stochastic analysis, we show that the optimal policy always exists and that it is characterized by three thresholds. There are investment and exit thresholds before investment, and there is a threshold for exit after investment. We also effect a comparative statics analysis of the thresholds with respect to the drift and the volatility of the Brownian motion. When the profit boost upon investment is sufficiently large, we find a novel result: the investment threshold decreases in volatility.

description: On March 10th, 2020 from 10am-3pm, UBC Library and the Health Libraries Association of British Columbia co-hosted a workshop on the Realist Review Process. The workshop presenters were Dr. Geoff Wong, UBC Peter Wall International Visiting Scholar, and Dr. Maura MacPhee and Katelyn Merrett, UBC School of Nursing. The presenters shared their research and this research methodology with librarians. Realist reviews are a knowledge synthesis methodology for researchers looking at complex policy questions. It addresses the question, ‘what works, for whom, in what circumstances, and how?’. An increasing number of researchers are receiving grants for realist reviews and this is a growing area of publication and has some interesting differences from other knowledge syntheses. Dr. Wong gives a background on this research methodology and Dr. MacPhee, Ms. Merrett and Dr. Wong share their realist research on teams and discuss opportunities for librarian partnerships with researchers on these reviews.

description: Für Landwirte steht inzwischen eine Vielzahl an Apps zur Unterstützung im Pflanzenschutz zur Verfügung. Jedoch ist nicht bekannt, welche Faktoren die Nutzungsentscheidung für Pflanzenschutz-Apps beeinflussen. Vor diesem Hintergrund ist es das Ziel dieses Beitrags zu überprüfen, ob ein Technologieakzeptanzmodell die Nutzungsentscheidung für Pflanzenschutz Smartphone-Apps erklären kann. Das Technologieakzeptanzmodell wird auf Basis einer Online-Umfrage mit 104 Landwirten mittels Partieller Kleinstquadrat Strukturgleichungsmodellierung und eines binären Logit-Modells geschätzt. Die Ergebnisse zeigen, dass alle Hypothesen des Technologieakzeptanzmodells bestätigt werden können. Weiterhin hat der Bildungsgrad des Landwirts einen positiven Effekt auf die Nutzungsentscheidung. Die Ergebnisse sind somit für Entwickler und Anbieter von Pflanzenschutz-Apps als auch für Forscher im Bereich der Präzisionslandwirtschaft interessant.

description: The recent discoveries of proximate quantum spin-liquid compounds and their potential application in quantum computing informs the search for new candidate materials for quantum spin-ice and spin-liquid physics. While the majority of such work has centered on members of the pyrochlore family due to their inherently frustrated linked tetrahedral structure, the rare-earth pyrogermanates also show promise for possible frustrated magnetic behavior. With the familiar stoichiometry $RE_2$Ge$_2$O$_7$, these compounds generally have tetragonal symmetry with a rare-earth sublattice built of a spiral of alternating edge and corner sharing rare-earth site triangles. Studies on Dy$_2$Ge$_2$O$_7$ and Ho$_2$Ge$_2$O$_7$ have shown tunable low temperature antiferromagnetic order, a high frustration index and spin-ice like dynamics. Here we use neutron diffraction to study magnetic order in Er$_2$Ge$_2$O$_7$ (space group $P4_{1}2_{1}2$ ) and find the lowest yet Neél temperature in the pyrogermanates of 1.15 K. Using neutron powder diffraction we find the magnetic structure to order with $k = (0,0,0)$ ordering vector, magnetic space group symmetry $P4_{1}^{'}2_{1}2^{'}$ and a refined Er moment of $m = 8.1 μ_B$ - near the expected value for the Er$^{3+}$ free ion. Provocatively, the magnetic structure exhibits similar 'local-Ising' behavior to that seen in the pyrocholres where the Er moment points up or down along the short Er-Er bond. Upon applying a magnetic field we find a first order metamagnetic transition at $\sim$ 0.35 T to a lower symmetry $P2_{1}^{'}2_{1}^{'}2$ structure. This magnetic transition involves an inversion of Er moments aligned antiparallel to the applied field describing a class I spin-flip type transition, indicating a strong local anisotropy at the Er site - reminiscent of that seen in the spin-ice pyrochlores.

description: This work reports on a unique tactile microprobe based
on a parallelogram kinematic made from monocrystalline silicon.
This kinematic, made out of an orthogonal cascade assembly of
three identical parallelograms, provides an isotropic behavior to
the microprobe. Each parallelogram deflects in only one direction
thanks to thin elastic silicon membrane hinges and their
displacements are recognized using piezoresistors integrated into
these hinges. Wide deflection ranges, isotropic behavior and low
mechanical stiffness of the new microprobe, as predicted by
simulations, could be verified in experiments. The fabrication, the
assembly and the contacting of the first microprobe prototype was
optimized to allow very compact integration into a Ø11 mm
housing. This make it suitable for metrology research laboratories
as well as industries equipped with conventional coordinate
measurement machines and even for a variety of other 3D
force/displacement measurements.

description: Various microprobes have been developed in the last decade to address the
needs of micrometrology. However, most microprobes are only employed in specialized
measuring machines located in a few research institutes and are not widespread in the
industry. This work aims to extend the capabilities of conventional coordinate
measuring machines (CMMs) towards measuring microgeometries through the low-cost
integration of a tactile microprobe. In order to demonstrate this, a gear measuring
instrument (GMI), which is a commercial CMM not specialized for measurements at the
microscale, has been equipped with a recently developed silicon-membrane-based
microprobe. In the first part of this work, the working principle of the microprobe, its
assembly and its integration into the GMI are described. Two different mounting setups
of the microprobe onto the GMI were evaluated and tested. Measurements on the GMI
were performed solely with the microprobe or by combining the microprobe and the
measurement system already present on the GMI. This combination makes it possible to
use the microprobe advantageously and to exchange it in a comfortable semi-automatic
way. To test these two mounting setups, a new involute scanning artifact (SAFT) with
superimposed waviness was measured.
