description: The Transiting Exoplanet Survey Satellite (TESS) has proven to be a powerful resource for uncovering planets, and the M-dwarfs have been established as favorable planet hosts. It has also become apparent that stellar multiplicity has wide-ranging implications for exoplanet detection and characterization, and that speckle imaging is one of the most efficient tools for probing these multi-star systems. We therefore present high-resolution imaging observations of 63 M-dwarf TOIs using speckle imagers at the 3.5m WIYN telescope, the 4.3m Lowell Discovery Telescope (LDT), and the twin 8.1m Gemini North and South telescopes. However, only one companion was detected. This finding is in contrast to the established 46% binarity rate in exoplanet host stars and the established 27% stellar multiplicity rate for field M-dwarfs. These results indicate that M-dwarf TOIs have a much lower multiplicity rate than field M-dwarfs. Our observations also imply that planet signals detected from M-dwarf TOIs are more likely to be real than those from higher-mass stars. Finally, these data support the observation that exoplanet-hosting binary stars have, in general, wider separations than field binaries.

Two-dimensional conformal sigma models and exact string solutions

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We discuss two classes of exact (in $\a'$) string solutions described by conformal sigma models. They can be viewed as two possibilities of constructing a conformal model out of the non-conformal one based on the metric of a $D$-dimensional homogeneous $G/H$ space. The first possibility is to introduce two extra dimensions (one space-like and one time-like) and to impose the null Killing symmetry condition on the resulting $2+D$ dimensional metric. In the case when the ``transverse" model is $n=2$ supersymmetric and the $G/H$ space is Kähler-Einstein the resulting metric-dilaton background can be found explicitly. The second possibility - which is realised in the sigma models corresponding to $G/H$ conformal theories - is to deform the metric, introducing at the same time a non-trivial dilaton and antisymmetric tensor backgrounds. The expressions for the metric and dilaton in this case are derived using the operator approach in which one identifies the equations for marginal operators of conformal theory with the linearised (near a background) expressions for the `$\b$-functions'. Equivalent results are then reproduced in the direct field-theoretical approach based on computing first the effective action of the $G/H$ gauged WZW model and then solving for the $2d$ gauge field. Both the bosonic and the supersymmetric cases are discussed. ( To be published in the Proceedings of the 26 Workshop ``From Superstrings to Supergravity", Erice, 5-12 December,1992.)

description: Tuberculosis (TB) is a preventable and treatable disease that is a major cause of global morbidity and mortality. Ireland is a high-income country which had an incidence of 5.6 cases of TB per 100,000 of population in 2019. Despite a low and declining incidence, TB care in Ireland must be improved if disease elimination (defined as an incidence of less than one case per million of population) is to be achieved. Internationally, there is a growing consensus that if TB is to be eliminated, programmatic management of latent TB infection (LTBI) is necessary, particularly in countries with a low disease incidence. Programmatic management involves identifying people or groups with a high prevalence of LTBI or risk of TB reactivation and engaging them in preventive care to reduce their individual or collective risk of TB disease. Once care is accessed, it must be of high-quality if patients with and at risk of TB disease are to avoid TB-related morbidity, mortality, and onward disease transmission to others. However, quality cannot be assumed, it must be defined, measured, and continually improved. This research evaluated the quality of care provided by a TB service in Ireland according to a quality framework and measures and benchmarked it against outcomes reported in the literature using international standards of TB care. The literature was systematically reviewed to identify the gaps in LTBI epidemiological and cascade of care research in Ireland. The direct and indirect cost of TB disease was in Ireland was also estimated. The research identified 21 areas where quality of TB care and LTBI research in Ireland should be improved and 23 recommendations to do so were made. The research identified the need to perform local and national cascade of LTBI care evaluations and research studies assessing the prevalence of LTBI and risk of TB reactivation in people in specific at-risk groups. This is needed to expand and scale programmatic LTBI management through local TB services. Patients with TB had a prolonged time from symptom onset to presentation to health care services, resulting in a high dependency on acute care pathways. The total annual cost of TB disease nationally was estimated at €15,906,424 in 2019. This research demonstrates the potential value a quality management approach has for TB elimination efforts in Ireland. Consideration should be given to the development of a national TB quality management programme as part of a funded national TB elimination strategy and programme.

description: The main ideas of the NLO calculations in Parton Reggeization Approach are illustrated on the example of the simplest NLO subprocess, which contributes to DIS: $γ^\star+R\to q + \bar{q}$. The double counting with the LO contribution $γ^\star + Q \to q$ is resolved. The problem of matching of the NLO results for single-scale observables in the Parton Reggeization Approach on the corresponding NLO results in the Collinear Parton Model is considered. In the developed framework, the usual NLO PDFs in the $\overline{MS}$-scheme can be consistently used as the collinear input for the NLO calculation in the Parton Reggeization Approach.

Slave-boson approach to the metallic stripe phases with large unit cells

description: Using a rotationally invariant version of the slave-boson approach in spin space we analyze the stability of stripe phases with large unit cells in the two-dimensional Hubbard model. This approach allows one to treat strong electron correlations in the stripe phases relevant in the low doping regime, and gives results representative of the thermodynamic limit. Thereby we resolve the longstanding controversy concerning the role played by the kinetic energy in stripe phases. While the transverse hopping across the domain walls yields the largest kinetic energy gain in the case of the insulating stripes with one hole per site, the holes propagating along the domain walls stabilize the metallic vertical stripes with one hole per two sites, as observed in the cuprates. We also show that a finite next-nearest neighbor hopping $t'$ can tip the energy balance between the filled diagonal and half-filled vertical stripes, which might explain a change in the spatial orientation of stripes observed in the high $T_c$ cuprates at the doping $x\simeq 1/16$.

description: We have used the high sensitivity and resolution of the IRAM interferometer to produce sub-arcsecond 12CO 2-1 images of 9 protoplanetary disks surrounding T Tauri stars in the Taurus-Auriga cloud (7 singles and 2 binaries). The images demonstrate the disks are in Keplerian rotation around their central stars. Using the least square fit method described in Guilloteau and Dutrey (1998), we derive the disk properties, in particular its inclination angle and rotation velocity, hence the dynamical mass. Since the disk mass is usually small, this is a direct measurement of the stellar mass. Typically, we reach an internal precision of 10% in the determinations of stellar mass. The over-all accuracy is limited by the uncertainty in the distance to a specific star. In a distance independent way, we compare the derived masses with theoretical tracks of pre-main-sequence evolution. Combined with the mean distance to the Taurus region (140 pc), for stars with mass close to 1 Msun, our results tend to favor the tracks with cooler photospheres (higher masses for a given spectral type). We find that in UZ Tau E the disk and the spectroscopic binary orbit appear to have different inclinations.

description: We study the random walk representation of the two-point function in statistical mechanics models near the critical point. Using standard scaling arguments we show that the critical exponent $ν$ describing the vanishing of the physical mass at the critical point is equal to $ν_θ/ d_w$. $d_w$ is the Hausdorff dimension of the walk. $ν_θ$ is the exponent describing the vanishing of the energy per unit length of the walk at the critical point. For the case of O(N) models, we show that $ν_θ=φ$, where $φ$ is the crossover exponent known in the context of field theory. This implies that the Hausdorff dimension of the walk is $φ/ν$ for O(N) models.

description: A prediction of the steady-state reconnection electric field in asymmetric reconnection is obtained by maximizing the reconnection rate as a function of the opening angle made by the upstream magnetic field on the weak magnetic field (magnetosheath) side. The prediction is within a factor of two of the widely examined asymmetric reconnection model [Cassak and Shay, Phys. Plasmas 14, 102114, 2007] in the collisionless limit, and they scale the same over a wide parameter regime. The previous model had the effective aspect ratio of the diffusion region as a free parameter, which simulations and observations suggest is on the order of 0.1, but the present model has no free parameters. In conjunction with the symmetric case [Liu et al., Phys. Rev. Lett. 118, 085101, 2017], this work further suggests that this nearly universal number 0.1, essentially the normalized fast reconnection rate, is a geometrical factor arising from maximizing the reconnection rate within magnetohydrodynamic (MHD)-scale constraints.

description: A Neural-Networks-based approach is proposed to construct a new type of exchange-correlation functional for density functional theory. It is applied to improve B3LYP functional by taking into account of high-order contributions to the exchange-correlation functional. The improved B3LYP functional is based on a neural network whose structure and synaptic weights are determined from 116 known experimental atomization energies, ionization potentials, proton affinities or total atomic energies which were used by Becke in his pioneer work on the hybrid functionals [J. Chem. Phys. ${\bf 98}$, 5648 (1993)]. It leads to better agreement between the first-principles calculation results and these 116 experimental data. The new B3LYP functional is further tested by applying it to calculate the ionization potentials of 24 molecules of the G2 test set. The 6-311+G(3{\it df},2{\it p}) basis set is employed in the calculation, and the resulting root-mean-square error is reduced to 2.2 kcal$\cdot$mol$^{-1}$ in comparison to 3.6 kcal$\cdot$mol$^{-1}$ of conventional B3LYP/6-311+G(3{\it df},2{\it p}) calculation.

description: Theoretical predictions for the core helium burning phase of stellar evolution are highly sensitive to the uncertain treatment of mixing at convective boundaries. In the last few years, interest in constraining the uncertain structure of their deep interiors has been renewed by insights from asteroseismology. Recently, Spruit (2015) proposed a limit for the rate of growth of helium-burning convective cores based on the higher buoyancy of material ingested from outside the convective core. In this paper we test the implications of such a limit for stellar models with a range of initial mass and metallicity. We find that the constraint on mixing beyond the Schwarzschild boundary has a significant effect on the evolution late in core helium burning, when core breathing pulses occur and the ingestion rate of helium is fastest. Ordinarily, core breathing pulses prolong the core helium burning lifetime to such an extent that models are at odds with observations of globular cluster populations. Across a wide range of initial stellar masses ($0.83 \leq M/\text{M}_\odot \leq 5$), applying the Spruit constraint reduces the core helium burning lifetime because core breathing pulses are either avoided or their number and severity reduced. The constraint suggested by Spruit therefore helps to resolve significant discrepancies between observations and theoretical predictions. Specifically, we find improved agreement for $R_2$, the observed ratio of asymptotic giant branch to horizontal branch stars in globular clusters; the luminosity difference between these two groups; and in asteroseismology, the mixed-mode period spacing detected in red clump stars in the \textit{Kepler} field.

description: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals that are extremely persistent in the environment. They classified as emerging contaminants and have been linked to impacts on the developmental, liver, immune, and thyroid systems, and are possible carcinogens. PFAS’ resistance to biodegradation and conventional oxidation processes make them one of the hardest chemicals to remove from water. With the discovery of PFAS in public water supplies, existing technologies are not capable of removing these recalcitrant contaminants to levels expected for the health of the public. Even in cases when conventional technologies can remove PFAS compounds, removal is often the separation of the contaminants from water to another phase for further treatment. Electrochemical treatment has been shown to not just transfer PFAS to other phases, but to destroy these compounds. These electrochemical systems have emerged as a novel water treatment technology which has been performed at both bench-scale and pilot-scale. This study explored the degradation of six of the most commonly regulated PFAS compounds on a scale that could be used in industrial applications. Two designs of Magnéli phase Ti4O7 anodes, solid and microporous which differ in flow pattern, were tested. These reactors were evaluated for the ability to destroy individual PFAS compounds at two voltages, two amperages, and with the addition of sodium sulfate to the base conductivity of sodium chloride. Previous Aclarity research designated the settings that were tested. The reactors were not capable of removing shorter-chain compounds, such as PFOA, PFHpA, and PFHxS, likely due to the hydrophilic functional groups. While PFOS, PFNA, and PFDA were easily removed due to their hydrophobic functional groups. The reactors removed the most contaminants at higher voltages and amperages. Further investigation is required to remove short-chain compounds with this large-scale reactor and to make the system more energy efficient.

description: Understanding how genetic changes allow emerging virus strains to escape the protection afforded by vaccination is vital for the maintenance of effective vaccines. In the current work, we use structural and phylogenetic differences between pairs of virus strains to identify important antigenic sites on the surface of the influenza A(H1N1) virus through the prediction of haemagglutination inhibition (HI) assay, pairwise measures of the antigenic similarity of virus strains. We propose a sparse hierarchical Bayesian model that can deal with the pairwise structure and inherent experimental variability in the H1N1 data through the introduction of latent variables. The latent variables represent the underlying HI assay measurement of any given pair of virus strains and help account for the fact that for any HI assay measurement between the same pair of virus strains, the difference in the viral sequence remains the same. Through accurately representing the structure of the H1N1 data, the model is able to select virus sites which are antigenic, while its latent structure achieves the computational efficiency required to deal with large virus sequence data, as typically available for the influenza virus. In addition to the latent variable model, we also propose a new method, block integrated Widely Applicable Information Criterion (biWAIC), for selecting between competing models. We show how this allows us to effectively select the random effects when used with the proposed model and apply both methods to an A(H1N1) dataset.

description: The common assumption that partnerships increase the effectiveness of threatened species conservation has never been tested. This question is complex, as there are many types of partnership, reasons to partner, and various costs incurred, and potential benefits received. Here we investigate the collaborative process of partnerships and how they can lead to better outcomes for threatened species conservation. We assess the conditions where partnerships have supported the solving of environmental problems, the activities carried out and the goals achieved, including whether ecological, economic and social objectives have been met.

description: This paper discusses the practical use of the saddle variational formulation for the weakly-constrained 4D-VAR method in data assimilation. It is shown that the method, in its original form, may produce erratic results or diverge because of the inherent lack of monotonicity of the produced objective function values. Convergent, variationaly coherent variants of the algorithm are then proposed whose practical performance is compared to that of other formulations. This comparison is conducted on two data assimilation instances (Burgers equation and the Quasi-Geostrophic model), using two different assumptions on parallel computing environment. Because these variants essentially retain the parallelization advantages of the original proposal, they often --- but not always --- perform best, even for moderate numbers of computing processes.
Magnetic Extraction of Spin Energy from a Black Hole
Creators: name: Krolik, Julian H.

Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Numerous variations have been proposed on the original suggestion by Blandford and Znajek that magnetic fields could be used to extract rotational energy from black holes. A new categorization of these variations is proposed so that they may be considered in a systematic way. "Black hole spindown" is defined more precisely, distinguishing decrease in the spin parameter a/M from decreases in angular momentum a and rotational kinetic energy, M - M_i. Several key physical questions are raised: Can the "stretched horizon" of a black hole communicate with the outside world? Do accretion disks bring any net magnetic flux to the black holes at their centers? Is the magnetic field adjacent to a black hole force-free everywhere?

description: The high brightness temperatures, $T_\mathrm{b}\gtrsim 10^{13}$ K, detected in several active galactic nuclei by RadioAstron space VLBI observations challenge theoretical limits. Refractive scattering by the interstellar medium may affect such measurements. We quantify the scattering properties and the sub-mas scale source parameters for the quasar B0529+483. Using RadioAstron correlated flux density measurements at 1.7, 4.8, and 22 GHz on projected baselines up to 240,000 km we find two characteristic angular scales in the quasar core, about 100 $μ$as and 10 $μ$as. Some indications of scattering substructure are found. Very high brightness temperatures, $T_\mathrm{b}\geq 10^{13}$ K, are estimated at 4.8 GHz and 22 GHz even taking into account the refractive scattering. Our findings suggest a clear dominance of the particle energy density over the magnetic field energy density in the core of this quasar.

description: Das Leibniz-Institut für Medienforschung | Hans-Bredow-Institut (HBI), Hamburg, untersucht, wie im digitalen Raum Kommunikationsprozesse und politische Meinungsbildung in demokratisch verfassten Gesellschaften funktionieren. Die Erforschung gesellschaftlicher Kommunikation unter den Bedingungen der Digitalisierung muss soziale Medien und Anwendungen Künstlicher Intelligenz wie Chat Bots und automatische Sprachverarbeitungsmodelle in den Blick nehmen. Mit der strategischen Erweiterung will das HBI die informationstechnische Forschung weiter ausbauen und das gesamte sozio-technische Ökosystem betrachten, das die Kommunikation in der digitalen Gesellschaft prägt. Diese Forschung ist von großer Bedeutung für den gesellschaftlichen Zusammenhalt, der durch Desinformation und Hassrede in den sozialen Medien zunehmend gefährdet wird.

description: The LIGO detection of gravitational waves (GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes (AST3), located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source (GW~170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the $i$-band magnitude declining from $17.23\pm0.13$ magnitude to $17.72\pm0.09$ magnitude in $\sim 1.8$ hour. The brightness and time evolution of the optical transient associated with GW~170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about $\sim 10^{-2}$ solar mass of radioactive material at a speed of up to $30\%$ the speed of light.

Magnetic Monopoles, Bogomol'nyi Bound and SL(2,Z) Invariance in String Theory
Creators: name: Sen, Ashoke
Publisher: name: arXiv
Year: 1993
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We show that in heterotic string theory compactified on a six dimensional torus, the lower bound (Bogomol'nyi bound) on the dyon mass is invariant under the SL(2,Z) transformation that interchanges strong and weak coupling limits of the theory. Elementary string excitations are also shown to satisfy this lower bound. Finally, we identify specific monopole solutions that are related via the strong-weak coupling duality transformation to some of the elementary particles saturating the Bogomol'nyi bound, and these monopoles are shown to have the same mass and degeneracy of states as the corresponding elementary particles.

description: The pervasive access to media options seriously challenges users’ self-regulatory abilities. One example of deficient self-regulation in the context of media use is procrastination—impulsively ‘giving in’ to available media options despite goal conflicts with more important tasks. This study investigaes procrastinatory media use across 3 types of media (TV, computer, smartphone) from a dual-systems perspective, taking both person-level and situation-level predictors into account. Results from a 14-day long diary study (N = 347) suggest that procrastinatory media use is driven by automatic media selection, which is facilitated by strong media habits (person level) and low motivation for behavioral control (situation level). The results underline the value of a dual-systems perspective on media choices in our media-saturated environment.
Pair-wise decoherence in coupled spin qubit networks

description: Experiments involving phase coherent dynamics of networks of spins, such as echo experiments, will only work if decoherence can be suppressed. We show here, by analyzing the particular example of a crystalline network of Fe8 molecules, that most decoherence typically comes from pairwise interactions (particularly dipolar interactions) between the spins, which cause `correlated errors'. However at very low T these are strongly suppressed. These results have important implications for the design of quantum information processing systems using electronic spins.
