description: From observations made with the ESPaDOnS spectropolarimeter, recently installed on the 3.6-m Canada--France--Hawaii Telescope, we report the discovery of a strong magnetic field in the Of?p spectrum variable HD 191612 -- only the second known magnetic O star (following theta1 Ori C). The stability of the observed Zeeman signature over four nights of observation, together with the non-rotational shape of line profiles, argue that the rotation period of HD 191612 is significantly longer than the 9-d value previously proposed. We suggest that the recently identified 538-d spectral-variability period is the rotation period, in which case the observed line-of-sight magnetic field of -220+-38 G implies a large-scale field (assumed dipolar) with a polar strength of about -1.5 kG. If confirmed, this scenario suggests that HD 191612 is, essentially, an evolved version of the near-ZAMS magnetic O star theta1 Ori C, but with an even stronger field (about 15 kG at an age similar to that of theta1Ori C). We suggest that the rotation rate of HD 191612, which is exceptionally slow by accepted O-star standards, could be due to angular-momentum dissipation through a magnetically confined wind.

description: The transformation of societal systems cannot be determined solely by any technological or economic assumed rationality. Rather, there is a wide range of social, political, and institutional factors that interact in a systemic fashion and influence their development. In managing Covid-19 pandemic, several compelling narratives seem to have played a significant role in the decision-making processes regarding which risk mitigation and management measures to implement. Many countries were to a large extent unprepared to such situation, even though forecasts about a significant probability in a pandemic to occur existed; national governments of several countries often acted in an uncoordinated manner, which resulted in many inconsistencies in the disaster risk-reduction processes. Limited evidence has also paved way for strategic narratives meant to persuade the public of the chosen set of actions, even through the degree of uncertainty regarding the outcomes of these was large, further complicating the situation. The acknowledgment of the multiple factors at stake in handling the crisis has more often than not been omitted from public communication, where public officials' statements mostly framed the problem unilaterally, basing their narratives on warnings coming from the medical and public health scientific community.

description: Let $K$ be a rationally null-homologous knot in a three-manifold $Y$. We construct a version of knot Floer homology in this context, including a description of the Floer homology of a three-manifold obtained as Morse surgery on the knot $K$. As an application, we express the Heegaard Floer homology of rational surgeries on $Y$ along a null-homologous knot $K$ in terms of the filtered homotopy type of the knot invariant for $K$. This has applications to Dehn surgery problems for knots in $S^3$. In a different direction, we use the techniques developed here to calculate the Heegaard Floer homology of an arbitrary Seifert fibered three-manifold.

description: Economic change and market dynamics have fundamentally altered the structure and performance of agricultural markets in the United States, Canada, and Mexico within the last 25 years. Many factors have helped shape the current North American food and fiber system, including technological change, domestic farm policies, international trade agreements, and the economic forces of supply and demand. Ratification of NAFTA, for example, helped integrate the North American market, sparking a surge in trade and investment among the United States, Canada, and Mexico. In recent years, efforts to further integrate the continental market seem to have slowed. Broadening the scope of NAFTA to include institutional reforms that lead to a more unified system of commercial law, the establishment of common antitrust and regulatory procedures, harmonization of product standards, and increased coordination of domestic farm, market, and macroeconomic policies would deepen market integration and enhance market efficiency and growth within North America.
Moments of spectral functions: Monte Carlo evaluation and verification

description: The subject of the present study is the Monte Carlo path-integral evaluation of the moments of spectral functions. Such moments can be computed by formal differentiation of certain estimating functionals that are infinitely-differentiable against time whenever the potential function is arbitrarily smooth. Here, I demonstrate that the numerical differentiation of the estimating functionals can be more successfully implemented by means of pseudospectral methods (e.g., exact differentiation of a Chebyshev polynomial interpolant), which utilize information from the entire interval $(-β\hbar / 2, β\hbar/2)$. The algorithmic detail that leads to robust numerical approximations is the fact that the path integral action and not the actual estimating functional are interpolated. Although the resulting approximation to the estimating functional is non-linear, the derivatives can be computed from it in a fast and stable way by contour integration in the complex plane, with the help of the Cauchy integral formula (e.g., by Lyness' method). An interesting aspect of the present development is that Hamburger's conditions for a finite sequence of numbers to be a moment sequence provide the necessary and sufficient criteria for the computed data to be compatible with the existence of an inversion algorithm. Finally, the issue of appearance of the sign problem in the computation of moments, albeit in a milder form than for other quantities, is addressed.

description: A previously unreported regime of type III intermittency is observed in a vertically vibrated milliliter-sized liquid drop submerged in a more viscous and less dense immiscible fluid layer supported by a hydrophobic solid plate. As the vibration amplitude is gradually increased, subharmonic Faraday waves are excited at the upper surface of the drop. We find a narrow window of vibration amplitudes slightly above the Faraday threshold, where the drop exhibits an irregular sequence of large amplitude bursting events alternating with intervals of low amplitude activity. The triggering physical mechanism is linked to the competition between surface Faraday waves and the shape deformation mode of the drop.

Reactive scattering can occur for the first two systems even when the molecules are in their ground rovibrational states, but is slower than vibrational relaxation in homonuclear systems. Implications for sympathetic cooling of heteronuclear molecules are discussed.

description: Water shortages in important grain-producing regions of China may significantly affect China's agricultural production potential and international markets. Falling ground-water tables and disruption of surface-water deliveries to important industrial and agricultural regions have provoked concern that a more dramatic crisis is looming unless effective water conservation policies can be put into place rapidly. While China's water use is unsustainable in some areas, there is substantial capacity to adapt and avert a more serious crisis. Recent changes in water management policies may serve to bring about more effective water conservation. This report provides an overview of these changes and some analysis of their effectiveness. Wheat is the most likely crop to show a fall in productiondue to water shortages, but cotton, corn, and rice may also be affected.

description: Magnon emission and excitation by a relativistic domain wall at a constant velocity in antiferromagnet is theoretically studied. A pair emission due to a quadratic magnon coupling is shown to be dominant. The emission corresponds in the comoving frame to a vacuum polarization induced by a zero-energy instability of the Lorentz-boosted anomalous response function. The emission rate is sensitive to the magnon dispersion and wall profile, and is significantly enhanced for a thin wall with velocity close to the effective light velocity. The Ohmic damping constant due to magnon excitation at low velocity is calculated.

description: By using slave particle (slave boson and slave fermion) technique on the Bose-Hubbard model, we study the finite temperature properties of ultracold Bose gases in optical lattices. The phase diagrams at finite temperature are depicted by including different types of slave particles and the effect of the finite types of slave particles is estimated. The superfluid density is evaluated using the Landau second order phase transition theory. The atom density, excitation spectrum and dispersion curve are also computed at various temperatures, and how the Mott-insulator evolves as the temperature increases is demonstrated. For most quantities to be calculated, we find that there are no qualitatively differences in using the slave boson or the slave fermion approaches. However, when studying the stability of the mean field state, we find that in contrast to the slave fermion approach, the slave boson mean field state is not stable. Although the slave boson mean field theory gives a qualitatively correct phase boundary, it corresponds to a local maximum of Landau free energy and can not describe the second order phase transition because the coefficient $a_4$ of the fourth order term is always negative in the free energy expansion.

description: Social accounting matrices (SAMs) are the core underlying data for economy-wide simulation models such as computable general equilibrium models. This paper reports the development of a SAM for Uzbekistan for the year 2014. The last SAM developed for Uzbekistan is based on the year 2001 (Müller, 2006) and Uzbekistan is listed among the top ten countries by GDP and population by the Global Trade and Analysis Project for which a recent input-output is missing. The SAM documented in this technical paper is characterized by a detailed representation of the agricultural sector. Generally, data availability in Uzbekistan is a challenge and the development process had to rely on myriad data sources. The final SAM values are estimated using an information-theoretic, cross-entropy approach. Using a Bayesian perspective, the degree of uncertainty of cell entries’ prior values reflected the availability and quality of data sources. In total, this SAM consists of 88 accounts. There are 31 commodity accounts and 31 accounts describe economic activities of which 17 activities are part of the agricultural sector. The factor accounts comprise five types of labor, capital, and main natural resources: land and water. There are three household accounts, one government, and five tax accounts. The authors hope that this SAM will allow researchers to investigate research questions that are of high priority for Uzbekistan’s future economic development, particularly those related to the future role of agriculture and water.
Stochastic process emerged from lattice fermion systems by repeated measurements and large-time limit

description: It is known that in quantum theory, measurements may suppress Hamiltonian dynamics of a system. A famous example is the `Quantum Zeno Effect'. This is the phenomena that if one repeats the measurements many times asking whether the system is in the same state as the one at the initial time until the fixed measurement time, then survival probability tends to 1 by taking the measurement interval to 0. This is the case for fixed measurement time. It is known that if one takes measurement time infinite at appropriate scaling, `Quantum Zeno Effect' does not occur and the effect of Hamiltonian dynamics emerges (Facchi and Ligabo 2017). In the present paper, we consider the long time repeated measurements and the dynamics of quantum many body systems in the scaling where the effect of measurements and dynamics are balanced. We show that the stochastic process, called symmetric simple exclusion process (SSEP), is obtained from the repeated and long time measurements of configuration of particles in finite lattice fermion systems. The emerging stochastic process is independent of potential and interaction of the underlying Hamiltonian of the system.

description: A dramatic increase in the total thermal conductivity (k) is observed in the Hidden Order (HO) state of single crystal URu2Si2. Through measurements of the thermal Hall conductivity, we explicitly show that the electronic contribution to k is extremely small, so that this large increase in k is dominated by phonon conduction. An itinerant BCS/mean-field model describes this behavior well: the increase in kappa is associated with the opening of a large energy gap at the Fermi Surface, thereby decreasing electron-phonon scattering. Our analysis implies that the Hidden Order parameter is strongly coupled to the lattice, suggestive of a broken symmetry involving charge degrees of freedom.

description: eHWC J2019+368 is one of the sources emitting $γ$-rays with energies higher than 100 TeV based on the recent measurement with the High Altitude Water Cherenkov Observatory (HAWC), and the origin is still in debate. The pulsar PSR J2021$+$3651 is spatially coincident with the TeV source. We investigate theoretically whether the multiband nonthermal emission of eHWC J2019+368 can originate from the pulsar wind nebula (PWN) G75.2$+$0.1 powered by PSR J2021$+$3651. In the model, the spin-down power of the pulsar is transferred to high-energy particles and magnetic field in the nebula. As the particles with an energy distribution of either a broken power-law or a power-law continually injected into the nebula, the multiband nonthermal emission is produced via synchrotron radiation and inverse Compton scattering. The spectral energy distribution of the nebula from the model with the reasonable parameters is generally consistent with the detected radio, X-ray and TeV $γ$-ray fluxes. Our study supports that the PWN has the ability to produce the TeV $γ$-rays of eHWC J2019+368, and the most energetic particles in the nebula have energies up to about $0.4$ PeV.

description: In this paper, we suppose a possible extension of Gibbs ensemble theory so that it can provide a reasonable description to phase transitions and spontaneous symmetry breaking. The extension is founded on three hypotheses, and can be regarded as a microscopic edition of the Landau phenomenological theory of phase transitions. Within its framework, the state of a system is determined by the evolution of order parameter with temperature according to such a principle that the entropy of the system will reach its minimum in this state. The evolution of order parameter can cause change in representation of the system Hamiltonian, different phases will realize different representations. Physically, it turns out that phase transition originates from the automatic interference among matter waves as temperature is cooled down. Typical quantum many-body systems are studied with this extended ensemble theory. In particular, the theory predicts that the specific heat Cp of liquid He II will vanish linearly as T tends to zero, which is anticipating experimental verifications.

description: Hintergrund: Der neuartige Coronavirus SARS-CoV-2 ist nun schon seit mehr als einem Jahr ständiger Begleiter unseres täglichen Lebens. Aufgrund der wirtschaftlichen und gesundheitlichen Schäden der Pandemie ist eine Analyse der Fallzahlen unumgänglich. Methode: Mit Hilfe von linearen Regressionsmodellen werden Zusammenhänge zwischen der 7-Tage-Inzidenz in Österreich und anderen Variablen quantifiziert. Um eine Reihung der erklärenden Variablen nach Wichtigkeit zu erhalten, werden der p-Wert eines t-Tests, das adjustierte Bestimmtheitsmaß R^2_adj und LASSO Pfade betrachtet. Die Berechnungen werden mit Hilfe des Statistikprogramm R durchgeführt. Ergebnisse: Wichtige erklärende Variablen bei der Beschreibung der 7-Tage-Inzidenz sind die Anzahl der durchgeführten Tests, die Außentemperatur, der Schweregrad der Lockdownmaßnahmen, Homeschooling und das Vorhandensein von Ferien, während Mobilitätsdaten von Apple weniger bedeutende erklärende Variablen darstellen. Insgesamt beträgt das Gütemaß des Fits R^2_adj = 0,9555. Schlussfolgerungen: Obwohl das lineare Regressionsmodell aufgrund komplexer Beziehungen zwischen den einzelnen Variablen an seine Grenzen stößt, fällt der Fit insgesamt sehr gut aus. Die Wahl erklärender Variablen ist dabei jedoch schwierig.
description: Background: The novel coronavirus SARS-CoV-2 has been a constant companion in our daily lives for more than a year now. Due to the economic and health damage of the pandemic, an analysis of the corona figures is inevitable. Method: Linear regression models are used to quantify the relationship between the 7 day incidence in Austria and other variables. To obtain a ranking of explanatory variables by importance, the p-value of a t-test, the adjusted coefficient of determination R^2_adj and LASSO paths are considered. The statistic software R is used for calculation. Results: For describing the 7 day incidence, important explanatory variables are the number of tests performed, outdoor temperature, the severity of lockdown measures, homeschooling, and the presence of holidays, while mobility data from Apple show lower importance. Overall, the goodness of fit is R^2_adj = 0.9555. Conclusions: Although the linear regression model reaches its limits due to complex relationships among certain variables, the overall fit turns out to be very good. However, the choice of explanatory variables is difficult.

description: We discuss a deterministic model of detector coupled to a two-level system (a qubit). The detector is a quasi-classical object whose dynamics is described by the kicked rotator Hamiltonian. We show that in the regime of quantum chaos the detector acts as a chaotic bath and induces decoherence of the qubit. We discuss the dephasing and relaxation rates and demonstrate that several features of Ohmic baths can be reproduced by our fully deterministic model. Moreover, we show that, for strong enough qubit-detector coupling, the dephasing rate is given by the rate of exponential instability of the detector's dynamics, that is, by the Lyapunov exponent of classical motion. Finally, we discuss the measurement in the regimes of strong and weak qubit-detector coupling. For the case of strong coupling the detector performs a measurement of the up/down state of the qubit. In the case of weak coupling, due to chaos, the dynamical evolution of the detector is strongly sensitive to the state of the qubit. However, in this case it is unclear how to extract a signal from any measurement with a coarse-graining in the phase space on a size much larger than the Planck cell.

How we fail children with developmental language disorder (McGregor, 2020)
Creators: name: McGregor, Karla K.
Publisher: name: ASHA journals
Year: 2020
Subjects: Language

description: Purpose: For over two decades, we have known that children with developmental language disorder (DLD) are underserved. We have also known that DLD does not attract the research attention that it merits given its prevalence and impact. The purposes of this clinical focus article are to present evidence that these failures continue, explore the reasons behind these failures, and propose solutions. Method: I reviewed the literature and applied bibliometric analysis procedures from Bishop (2010) to quantify research efforts aimed at DLD compared to other neurodevelopmental disorders.Results: The percentage of children who are deemed eligible for clinical services because of DLD continues to fall well short of estimates based on the prevalence of DLD in community samples. The amount of research conducted on DLD relative to other neurodevelopmental disorders remains low. Contributing factors include a lack of awareness of DLD, the hidden nature of DLD, entrenched policies, and the dissonance created when speech-language pathologists must diagnose DLD in school settings.Conclusions: Expanded approaches to supporting children with DLD are required. These might include engagement in advocacy and awareness campaigns; clearer communication with the families we serve and enhanced collaborations with classroom teachers; the implementation of school-based language screenings; participation in policymaking; and the development of service delivery models that operate alongside those that exist in our schools and complement their function.

Phase-dependent interference mechanisms in a three-level Lambda system driven by a quantized laser field
Creators: name: Evers, Joerg
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The dynamics of an atomic few-level system can depend on the phase of driving fields coupled to the atom if certain conditions are satisfied. This is of particular interest to control interference effects, which can alter the system properties considerably. In this article, we discuss the mechanisms of such phase control and interference effects in an atomic three-level system in $Λ$ configuration, where the upper state spontaneously decays into the two lower states. The lower states are coupled by a driving field, which we treat as quantized. This allows for an interpretation on the single photon level for both the vacuum and the driving field. By analyzing the system behavior for a driving field initially in non-classical states with only few Fock number states populated, we find that even though the driving field is coupled to the lower states only, it induces a multiplet of upper states. Then interference occurs independently in three-level subsystems in $V$ configuration, each formed by two adjacent upper states and a single dressed lower state.

Mobility of lead in the roadside soils of the 176th Street and Transcanada Highway Interchange, Surrey, BC
Creators: name: Lee, Norman
Publisher: name: University of British Columbia
Year: 2009

description: Tetra ethyl lead was used as a fuel additive to improve the octane rating of automotive gasoline until the early 1990s. Consequently soil lead concentrations in excess of the provincially determined standard are present at a number of highway construction sites. Presently, the Ministry of Transportation is obligated to mitigate risks by excavating and disposing of the contaminated soil present at each highway project at considerable cost. This is done without consideration of a significant risk-determining factor, the mobility of the contaminant. The contaminated soils of the 176th Street TransCanada Highway Interchange, Surrey BC were studied to determine whether it would be acceptable to leave lead-contaminated roadside soils in place. Significant lead accumulations of up to 1430 mg/kg were found in the roadside soils of the 176th Street TransCanada Highway Interchange Site. The distribution of lead contamination followed the characteristic distribution given in the literature. Soil lead concentrations decreased rapidly to background levels at 10 m away from the roadside and at the 60 cm depth. Leachant concentrations of all 24 samples (5 depths from 6 borehole sets) subjected to the batch desorption test (24 hours, pH 3.5) were below the 5 ppm method detection limit. Estimated adsorption capacities of 24 samples (from 6 borehole sets) subjected to the batch adsorption test ranged from 4000-17000 mg/kg. Estimated capacities were 4 to 17 times the highest accumulated soil lead concentration found on the site. Annual source indicators have dropped drastically with the phase out of leaded gasoline, therefore it is unlikely that adsorption capacity will be reached in the near future. The results suggest leaving the lead-contaminated soil in place may be acceptable. A multiple regression analysis with commonly measured soil properties (soil pH, total soil lead, silt and clay fraction, soil carbon) showed estimated adsorption capacity was strongly correlated with soil carbon content. Therefore, organic matter is recommended as a remedial measure in the event of a lead spill.

description: Poincare gauge theories that, in the absence of spinning matter, reduce to the one-parameter teleparallel theory are investigated with respect to their mathematical consistency and experimental viability. It is argued that the theories can be consistently coupled to the known standard model particles. Moreover, we establish the result that in the classical limit, such theories share a large class of solutions with general relativity, containing, among others, the four classical black hole solutions (Schwarzschild, Reisner-Nordstrom, Kerr and Kerr-Newman), as well as the complete class of Friedman-Robertson-Walker cosmological solutions, thereby extending older viability results that were restricted to the correct Newtonian limit and to the existence of the Schwarzschild solution.

However, numerical integrations show that it was previously a Centaur before reaching its current Jupiter Trojan-like orbit in 2018 July, and is expected to return to being a Centaur in 2028 February, before eventually becoming a Jupiter-family comet in 2063 February. The case of P/2019 LD2 highlights the need for mechanisms to quickly and reliably dynamically classify small solar system bodies discovered in current and upcoming wide-field surveys.

description: Focus of this study is to explore some aspects of mathematical foundations for using complex manifolds as a model for space-time. More specifically, certain equations of motions have been derived as a Projective geodesic on a real manifold embedded within a complex one. To that goal, first the geodesic on complex manifold has been computed using local complex and conjugate coordinates, and then its projection on the real sub-manifold has been studied. The projective geodesic, thus obtained, is shown to have additional terms beyond the usual Christoffel symbols, and hence expands the geodesic to capture effects beyond the mere gravitational ones.

description: Direct imaging of Earth-like planets from space requires dedicated observatories, combining large segmented apertures with instruments and techniques such as coronagraphs, wavefront sensors, and wavefront control in order to reach the high contrast of 10^10 that is required. The complexity of these systems would be increased by the segmentation of the primary mirror, which allows for the larger diameters necessary to image Earth-like planets but also introduces specific patterns in the image due to the pupil shape and segmentation and making high-contrast imaging more challenging. Among these defects, the phasing errors of the primary mirror are a strong limitation to the performance. In this paper, we focus on the wavefront sensing of segment phasing errors for a high-contrast system, using the COronagraphic Focal plane wave-Front Estimation for Exoplanet detection (COFFEE) technique. We implemented and tested COFFEE on the High-contrast imaging for Complex Aperture Telescopes (HiCAT) testbed, in a configuration without any coronagraph and with a classical Lyot coronagraph, to reconstruct errors applied on a 37 segment mirror. We analysed the quality and limitations of the reconstructions. We demonstrate that COFFEE is able to estimate correctly the phasing errors of a segmented telescope for piston, tip, and tilt aberrations of typically 100nm RMS. We also identified the limitations of COFFEE for the reconstruction of low-order wavefront modes, which are highly filtered by the coronagraph. This is illustrated using two focal plane mask sizes on HiCAT. We discuss possible solutions, both in the hardware system and in the COFFEE optimizer, to mitigate these issues.

Type II superconductivity and magnetic flux transport in neutrons stars

description: The transition to a type II proton superconductor which is believed to occur in a cooling neutron star is accompanied by changes in the equation of hydrostatic equilibrium and by the formation of proton vortices with quantized magnetic flux. Analysis of the electron Boltzmann equation for this system and of the proton supercurrent distribution formed at the transition leads to the derivation of a simple expression for the transport velocity of magnetic flux in the liquid interior of a neutron star. This shows that flux moves easily as a consequence of the interaction between neutron and proton superfluid vortices during intervals of spin-down or spin-up in binary systems. The differences between the present analysis and those of previous workers are reviewed and an error in the paper of Jones (1991) is corrected.

Excitations and number fluctuations in an elongated dipolar Bose-Einstein condensate

description: We study the properties of a magnetic dipolar Bose-Einstein condensate (BEC) in an elongated (cigar shaped) confining potential in the beyond quasi-one-dimensional (quasi-1D) regime. In this system the dipole-dipole interactions (DDIs) develop a momentum-dependence related to the transverse confinement and the polarization direction of the dipoles. This leads to density fluctuations being enhanced or suppressed at a length scale related to the transverse confinement length, with local atom number measurements being a practical method to observe these effects in experiments. We use meanfield theory to describe the ground state, excitations and the local number fluctuations. Quantitative predictions are presented based on full numerical solutions and a simplified variational approach that we develop. In addition to the well-known roton excitation, occurring when the dipoles are polarized along a tightly confined direction, we find an "anti-roton" effect for the case of dipoles polarized along the long axis: a nearly non-interacting ground state that experiences strongly repulsive interactions with excitations of sufficiently short wavelength.

Cryogenic small-signal conversion with relaxation oscillations in Josephson junctions

description: Broadband detection of small electronic signals from cryogenic devices, with the option of simple implementation for multiplexing, is often a highly desired, although non-trivial task. We investigate and demonstrate a small-signal analog-to-frequency conversion system based on relaxation oscillations in a single Josephson junction. Operation and stability conditions are derived, with special emphasis on noise analysis, showing the dominant noise sources to originate from fluctuation processes in the junction. At optimum conditions the circuit is found to deliver excellent noise performance over a broad dynamic range. Our simple models apply within the regime of classical Josephson junction and circuit dynamics, which we confirm by experimental results. A discussion on possible applications includes a measurement of the response to a cryogenic radiation detector.

description: this project presents a simulation study of the influence of various factors on the energy consumption of an electric vehicle (EV). Because of the limited amount of energy contained in the battery, EVs are very sensitive to parameters that can influence their energy consumption and can then induce huge variations in their actual range. Among all these factors, driving conditions, the impact of auxiliaries, driver aggressiveness, and braking energy recovery strategy should be considered as the main factors influencing EV energy consumption. In this project we will model and simulate the electric vehicle's drive train and the factors affecting its range, then we will present some methods for optimizing and improving the range and performance of the electric car.

description: We observed SDSS J0836+0054, the most distant radio-loud quasar known at present (z=5.774) with the European Very Long Baseline Interferometry (VLBI) Network at the 5 GHz frequency on 2003 November 4. The source is compact at the milli-arcsecond (mas) angular scale with a flux density of 0.34 mJy. The observations with the Very Large Array (VLA) made on the consecutive day support a conclusion that the radio emission from SDSS J0836+0054 is essentially confined within the central 40 pc. Based on our phase-referenced VLBI observation, we obtained the astrometric position of the source accurate to ~2 mas.

description: Geyer and Jarden proved several results for torsion points of elliptic curves defined over the fixed field by finitely many elements in the absolute Galois group of a finitely generated field over the prime field in its algebraic closure. As an analogue of these results, this paper studies torsion points of Drinfeld modules defined over the fixed field by finitely many elements in the absolute Galois group of a finitely generated function field in its algebraic closure. We prove some results which are similar to those of Geyer and Jarden.
