Physical properties and evolutionary status of Cepheids in eclipsing binaries in the LMC
Creators: name: Pilecki, Bogumil
Publisher: name: Zenodo
Year: 2019

description: Cepheids are important distance indicators in the local Universe and key objects for testing the predictions of stellar evolution and stellar pulsation theories. A presence of Cepheids in eclipsing binary systems give us an opportunity to measure and study their physical parameters, including the mass. I will present the most important knowledge we obtained from the observations and analysis of 10 Cepheids in eclipsing binaries in the Large Magellanic Clouds, like firm relations between such measured parameters as period, mass and radius. The results based on evolution and pulsation models can be now compared with observations and challenged. The study resulted in finding various evidences for binary interactions during the evolution and a non-pulsating object inside the instability strip. Our measurements provide strong constraints for solving the famous Cepheid mass discrepancy problem. We have also measured the first dynamical mass and determined the evolutionary status of a type II Cepheid. A presence of complex ringed disk structures were also detected around the companions to type II Cepheids.

description: We report on our three-dimensional (3D) magnetohydrodynamic (MHD) simulations of cylindrical weakly twisted flux tubes emerging from 18 Mm below the photosphere. We perform a parametric study, by varying the initial magnetic field strength ($B_0$), radius ($R$), twist ($α)$ and length of the emerging part of the flux tube ($λ$) to investigate how these parameters affect the transfer of the magnetic field from the convection zone to the photosphere. We show that the efficiency of emergence at the photosphere (i.e. how strong the photospheric field will be in comparison to $B_0$) depends not only on the $B_0$ but also the morphology of the emerging field and the twist. We show that parameters such as $B_0$ and magnetic flux cannot alone determine whether a flux tube will emerge to the solar surface. For instance, high-$B_0$ (weak-$B_0$) fields may fail (succeed) to emerge at the photosphere, depending on their geometrical properties. We also show that the photospheric magnetic field strength can vary greatly for flux tubes with the same $B_0$ but different geometric properties. Moreover, in some cases we have found scaling laws, whereby the magnetic field strength scales with the local density as $B\propto ρ^κ$, where $κ\approx 1$ deeper in the convection zone and $κ<1$, close to the photosphere. The transition between the two values occurs approximately when the local pressure scale ($H_p$) becomes comparable to the diameter of the flux tube ($H_p\approx2R$). We derive forms to explain how and when these scaling laws appear and compare them with the numerical simulations.

description: In this paper we study the first-order efficiency and asymptotic normality of the maximum likelihood estimator obtained from dependent observations. Our conditions are somewhat weaker than usual, in that we do not require convergences in probability to be uniform or thirdorder derivatives to exist; moreover, the conditions will appear to be readily verifiable. This paper builds on Witting and Nalle's result concerning the asymptotic normality of the maximum likelihood estimator obtained from independent and identically distributed observations, and on a martingale theorem by McLeish.

description: Lack of knowledge about the background expansion history of the Universe from independent observations makes it problematic to obtain a precise and accurate estimation of the Hubble constant $H_0$ from gravitational wave standard sirens, even with electromagnetic counterpart redshifts. Simply fitting simultaneously for the matter density in a flat \lcdm\ model can reduce the precision on $H_0$ from 1\% to 5\%, while not knowing the actual background expansion model of the universe (e.g.\ form of dark energy) can introduce substantial bias in estimation of the Hubble constant. When the statistical precision is at the level of 1\% uncertainty on $H_0$, biases in non-\lcdm\ cosmologies that are consistent with current data could reach the 3$σ$ level. To avoid model-dependent biases, statistical techniques that are appropriately agnostic about model assumptions need to be employed.

description: We give a derivation of general relativity and the gauge principle that is novel in presupposing neither spacetime nor the relativity principle. We consider a class of actions defined on superspace with two key properties. The first is 3-coordinate invariance. This is the only postulated symmetry, and it leads to the standard momentum constraint. The second property is that the Lagrangian is constructed from a `local' square root of an expression quadratic in the velocities, `local' because it is taken before integration over 3-space. It gives rise to quadratic constraints that do not correspond to any symmetry and are not, in general, propagated by the Euler-Lagrange equations. Therefore these actions are internally inconsistent. Only one action of this form is well behaved: the Baierlein-Sharp-Wheeler reparametrisation-invariant action for GR. From this viewpoint, spacetime symmetry is emergent. It appears as a `hidden' symmetry in the (underdetermined) solutions of the evolution equations, without being manifestly coded into the action itself. In addition, propagation of the constraints acts as a striking selection mechanism beyond pure gravity. If a scalar field is included in the configuration space, it must have the same characteristic speed as gravity. Thus Einstein causality emerges. Finally, self-consistency requires that any 3-vector field must satisfy Einstein causality, the equivalence principle and, in addition, the Gauss constraint. Therefore we recover the standard (massless) Maxwell equations.

description: A recent proposal of accelerator based fusion reactor considers a scheme where an ion beam from the accelerator hits the target plasma on the resonance of the fusion reaction so that the reactivity ($σv$) can be an order of magnitude larger than that of a thermonuclear reactor. One of the important inputs is the stopping power which is needed to assess the energy loss of the beam in the plasma. In this work, we shall use the analytic formulation of Brown, Preston and Singleton~\cite{Brown:2005ji} to calculate the temperature dependence of the stopping power due to the target $t, {}^3H_e$, and ${}^{11}B$ plasmas in the resonance regions of their respective fusion reactions, i.e., $ d + t \rightarrow n + α, d + {}^3H_e \rightarrow p + α$, and $p + {}^{11}B \rightarrow 3 α$. It is found that the calculated stopping power, especially when the quantum corrections are included, does not go down with temperature as fast at $T^{-3/2}$. Instead it decreases slower, more like $T^{-x}$ with $x \le 1$ in the range of T from $\sim$ 5 to 50 keV for $d$ on $t$ and ${}^3H_e$ plasmas around their resonance energies.

description: In this contribution we evaluate the impact of filtering techniques in enhancing the accuracy of forecasts of optical turbulence and atmospheric parameters critical for ground-based telescopes. These techniques make use of the data continuously provided by the telescope sensors and instruments to improve the performances of real-time forecasts which have an impact on the telescope operation. In previous works we have already shown how a mesoscale high-frequency forecast (Meso-NH and Astro-Meso-Nh models) can produce reliable predictions of different atmospheric parameters and the optical turbulence. The mesoscale forecast has an advantage on the global model in having a better implementation of the physical atmospheric processes, including turbulence, and produces an output with greater spatial resolution (up to 100m or beyond). Filtering techniques that make use of the real-time sensor data at the telescope may help in removing potential biases and trends which have an impact on short term mesoscale forecast and, as a consequence, may increase the accuracy of the final output. Given the complexity and cost of present and future top-class telescope installations, each improvement of forecasts of future observing conditions will definitely help in better allocating observing time, especially in queue-mode operation, and will definitely benefit the scientific community in medium-long term.

description: A systematic investigation of the microscopic conditions stabilizing itinerant ferromagnetism of correlated electrons in a single-band model is presented. Quantitative results are obtained by quantum Monte Carlo simulations for a model with Hubbard interaction U and direct Heisenberg exchange interaction F within the dynamical mean-field theory. Special emphasis is placed on the investigation of (i) the distribution of spectral weight in the density of states, (ii) the importance of genuine correlations, and (iii) the significance of the direct exchange, for the stability of itinerant ferromagnetism at finite temperatures. We find that already a moderately strong peak in the density of states near the band edge suffices to stabilize ferromagnetism at intermediate U-values in a broad range of electron densities n. Correlation effects prove to be essential: Slater--Hartree-Fock results for the transition temperature are both qualitatively and quantitatively incorrect. The nearest-neighbor Heisenberg exchange does not, in general, play a decisive role. Detailed results for the magnetic phase diagram as a function of U, F, n, temperature T, and the asymmetry of the density of states are presented and discussed.

description: Strukturveränderungen in der Weinwirtschaft Darstellung und Diskussion Der deutsche Weinmarkt ruft strukturelle Veränderungen herbei, mit welchen Unternehmen entlang der Wertschöpfungskette unterschiedlich umgehen. Um die Veränderungen seit dem Beginn des 21. Jahrhunderts zu veranschaulichen, werden in diesem Beitrag die Produktions- und Konsumdaten aus den Jahren 2000, 2010 und 2018 miteinander verglichen. Wohingegen die Gesamtgröße des Wein- und Sektmarktes in Deutschland sowie die in Deutschland gesamtproduzierte Menge Wein über die letzten zwei Jahrzehnte in etwa gleichblieben, zeigen sich Veränderungen im Hinblick auf Absatzkanäle, im Handel, in weiterverarbeitenden Unternehmen, bis hin zu den Produktionsstrukturen in der Primärproduktion. Ziel dieses Beitrags ist es, einerseits die Entwicklung der einzelnen Stufen der Wertschöpfungskette Wein in Deutschland aufzuzeigen und andererseits zu untersuchen, wie Unternehmen auf verschiedenen Ebenen der Wertschöpfungskette auf diese Entwicklung reagieren bzw. mit diesen umgehen. Dazu werden drei ausgewählte Studien kurz vorgestellt. Diese umfassen den selbstständigen Lebensmitteleinzelhandel, die Weinkommissionäre sowie die zukaufenden Weingüter. Basierend auf den Ergebnissen werden Implikationen für Politik und Verbände aufgezeigt und die Limitation der Studie mit Hinblick auf die Datenverfügbarkeit diskutiert. Summary Structural Changes in the German Wine Industry Description and Discussion The German wine market is calling for structural changes, which companies along the value chain are addressing in different ways. To illustrate the changes since the beginning of the 21st century, this paper compares production and consumption data from 2000, 2010 and 2018. Whereas the overall size of the wine and sparkling wine market in Germany as well as the total amount of wine produced in Germany remained more or less the same over the last two decades, changes can be seen with regard to sales channels, in trade, in processing companies, up on to production structures in primary production. The aim of this article is, on the one hand, to show the development of the individual stages of the wine value chain in Germany and, on the other hand, to examine how companies at different levels of the value chain react to or deal with these developments. To this end, three selected studies are presented briefly. These include independent food retailers, wine commission agents and grape-buying wine estates. Based on the results, implications for politics and professional industry bodys will be presented and the limitations of the study with regard to data availability will be discussed.

On the universality of compact polymers

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Fully packed loop models on the square and the honeycomb lattice constitute new classes of critical behaviour, distinct from those of the low-temperature O(n) model. A simple symmetry argument suggests that such compact phases are only possible when the underlying lattice is bipartite. Motivated by the hope of identifying further compact universality classes we therefore study the fully packed loop model on the square-octagon lattice. Surprisingly, this model is only critical for loop weights n < 1.88, and its scaling limit coincides with the dense phase of the O(n) model. For n=2 it is exactly equivalent to the selfdual 9-state Potts model. These analytical predictions are confirmed by numerical transfer matrix results. Our conclusions extend to a large class of bipartite decorated lattices.

description: In the presence of crossed electric and magnetic fields, a graphene ribbon has chiral states running along sample edges and along boundaries between $p$-doped and $n$-doped regions. We here consider the scattering of edge states into interface states, which takes place whereever the $pn$ interface crosses the sample boundary, as well as the reverse process. For a graphene ribbon with armchair boundaries, the evolution of edge states into interface states and {\em vice versa} is governed by the conservation of valley isospin. Although valley isospin is not conserved in simplified models of a ribbon with zigzag boundaries, we find that arguments based on isospin conservation can be applied to a more realistic modeling of the graphene ribbon, which takes account of the lifting of electron-hole degeneracy. The valley isospin of interface states is an important factor determining the conductance of a graphene $pn$ junction in a quantizing magnetic field.

description: Using the data release 1 of the Hyper Suprime-Cam Subaru Strategic Program covering about 130 square degrees at high galactic latitudes, we have obtained L dwarf counts based on the selection criteria on colors, limiting magnitude and PSF morphology using $i$, $z$, and $y$ bands. 3665 L dwarfs brighter than $z=24$ have been detected by these criteria. The surface number counts obtained differentially in $z$ magnitude are compared with predictions of an exponential disk model to estimate the thin-disk scale height in the vicinity of the Sun. In the exponential disk model, we first fix the local luminosity function (LLF) to the mean LLF of Cruz et al. (2007) and derive the best fit scale height of 260 pc. However this fit appears to be poor. We then allow the LLF to vary along with the scale height. We use the LLF of Cruz et al. as a starting point. The best-fit model is found for the vertical scale height of 380 pc. However the $χ^2$ minimum is rather broad and the 90% confidence interval is between 320 and 520 pc. We investigate another model by varying the scale height and the density of the brightest magnitude bin, while other magnitude bins are fixed to the mean LLF of Cruz et al.. We find an equally good fit with the two free parameters and the best-fit scale height is again 380 pc, but the 90% confidence interval is between 340 and 420 pc.

description: A correlated material in the vicinity of an insulator-metal transition (IMT) exhibits rich phenomenology and variety of interesting phases. A common avenue to induce IMTs in Mott insulators is doping, which inevitably leads to disorder. While disorder is well known to create electronic inhomogeneity, recent theoretical studies have indicated that it may play an unexpected and much more profound role in controlling the properties of Mott systems. Theory predicts that disorder might play a role in driving a Mott insulator across an IMT, with the emergent metallic state hosting a power law suppression of the density of states (with exponent close to 1; V-shaped gap) centered at the Fermi energy. Such V-shaped gaps have been observed in Mott systems but their origins are as yet unknown. To investigate this, we use scanning tunneling microscopy and spectroscopy to study isovalent Ru substitutions in Sr$_3$(Ir$_{1-x}$Ru$_x$)$_2$O$_7$ which drives the system into an antiferromagnetic, metallic state. Our experiments reveal that many core features of the IMT such as power law density of states, pinning of the Fermi energy with increasing disorder, and persistence of antiferromagnetism can be understood as universal features of a disordered Mott system near an IMT and suggest that V-shaped gaps may be an inevitable consequence of disorder in doped Mott insulators.

description: Forecast of the atmospheric parameters and optical turbulence applied to the ground-based astronomy is very crucial mainly for the queue scheduling. So far, most efforts have been addressed by our group in developing algorithms for the optical turbulence (CN2) and annexed integrated astroclimatic parameters and quantifying the performances of the Astro-Meso-Nh package in reconstructing such parameters. Besides, intensive analyses on the Meso-Nh performances= in reconstructing atmospheric parameters relevant for the ground-based astronomy has been carried out. Our studies referred always to the night time regime. To extend the applications of our studies to the day time regime, we present, in this contribution, preliminary results obtained by comparing model outputs and measurements of classical atmospheric parameter relevant for the ground-based astronomy in night and day time. We chose as a test case, the Roque de los Muchachos Observatory (Canary Islands), that offers a very extended set of measurements provided by different sensors belonging to different telescopes on the same summit/Observatory. The convective regime close to the ground typical of the day time is pretty different from the stable regime characterising the night time. This study aims therefore to enlarge the domain of validity of the Astro-Meso-Nh code to new turbulence regimes and it permits to cover the total 24 hours of a day. Such an approach will permit not only an application to solar telescopes (e.g. EST) but also applications to a much extended set of scientific fields, not only in astronomical context such as satellite communications.

description: We study the magnetic response due to neutral solitons induced by disorder in polymer materials. We account for interchain interactions, which, if sufficiently strong, result in a bond-ordered phase, in which the neutral solitons are bound into pairs. We analytically calculate the corresponding pair size distribution. As the spins of the solitons have a distance dependent antiferromagnetic coupling, this allows us to calculate the magnetic susceptibility in the ordered phase. At low temperatures, the result deviates from the usual Curie behavior in a way that depends on the relative strength of the disorder and the interchain interactions. We compare our results to the observed magnetic susceptibility of trans-polyacetylene and we suggest new experiments extending towards lower temperatures.

description: Distributed Denial-of-Service (DDoS) is a menace for service provider and prominent issue in network security. Defeating or defending the DDoS is a prime challenge. DDoS make a service unavailable for a certain time. This phenomenon harms the service providers, and hence, loss of business revenue. Therefore, DDoS is a grand challenge to defeat. There are numerous mechanism to defend DDoS, however, this paper surveys the deployment of Bloom Filter in defending a DDoS attack. The Bloom Filter is a probabilistic data structure for membership query that returns either true or false. Bloom Filter uses tiny memory to store information of large data. Therefore, packet information is stored in Bloom Filter to defend and defeat DDoS. This paper presents a survey on DDoS defending technique using Bloom Filter.

description: Recently, Kavan Modi \emph{et al.} found that masking quantum information is impossible in bipartite scenario in [Phys. Rev. Lett. \textbf{120}, 230501 (2018)]. This adds another item of the no-go theorems. In this paper, we present some new schemes different from error correction codes, which show that quantum states can be masked when more participants are allowed in the masking process. Moreover, using a pair of mutually orthogonal Latin squares of dimension $d$, we show that all the $d$ level quantum states can be masked into tripartite quantum systems whose local dimensions are $d$ or $d+1$. This highlight some difference between the no-masking theorem and the classical no-cloning theorem or no-deleting theorem.

Abstract:

Neutrinos are the most elusive particles in the Standard Model, and many of their properties have not yet been fully understood. Among them, neutrino electromagnetic properties such as magnetic moment and millicharge have become objects of extensive research. Consequently, there is a pressing need for experiments capable of precisely probing them at a high precision level.In this presentation, I will discuss the status of the constraints on such properties coming from experiments designed to measure coherent elastic neutrino-nucleus scattering (CEvNS) and xenon-based dark matter detectors, which are sensitive to the elastic scattering of solar neutrinos off atomic electrons. I will present the latest constraints obtained by the combined analysis of the COHERENT data on CsI and LAr detectors with the recent results from the CEvNS observation at the Dresden-II power plant site with a germanium detector [1]. Then, I will discuss the results from the LUX-ZEPLIN dark matter detector [2], focusing on the impact of adopting different theoretical descriptions for the interaction of neutrinos with atomic electrons. Finally, I will show that the LUX-ZEPLIN data allows us to set the second best laboratory constraint (second only to the recent XENONnT result) namely μeff<1.1×10−11 μB at 90% C.L., which improves by almost a factor of three the Borexino Collaboration limit. Moreover, exploiting the so-called equivalent photon approximation, we obtain the most stringent limit on the neutrino millicharge, namely |qeff|<1.5×10−13 e0 at 90% C.L., which represents a great improvement with respect to the previous laboratory bounds.

A Sober Assessment of Cosmology at the New Millennium

description: Cosmology is the dot com of the sciences. Boom or bust. It is about nothing less than the origin and evolution of the Universe, the all of everything. It is the boldest of enterprises and not for the fainthearted. Cosmologists are the flyboys of astrophysics, and they often live up to all that image conjures up. It is hardly surprising then that words written about cosmology are rarely balanced. They verve to one extreme or the other. .... Once or twice, I have probably been guilty of irrational exuberance when it comes to cosmology.

description: It remains a huge challenge to design effective and efficient trackers under complex scenarios, including occlusions, illumination changes and pose variations. To cope with this problem, a promising solution is to integrate the temporal consistency across consecutive frames and multiple feature cues in a unified model. Motivated by this idea, we propose a novel correlation filter-based tracker in this work, in which the temporal relatedness is reconciled under a multi-task learning framework and the multiple feature cues are modeled using a multi-view learning approach. We demonstrate the resulting regression model can be efficiently learned by exploiting the structure of blockwise diagonal matrix. A fast blockwise diagonal matrix inversion algorithm is developed thereafter for efficient online tracking. Meanwhile, we incorporate an adaptive scale estimation mechanism to strengthen the stability of scale variation tracking. We implement our tracker using two types of features and test it on two benchmark datasets. Experimental results demonstrate the superiority of our proposed approach when compared with other state-of-the-art trackers. project homepage http://bmal.hust.edu.cn/project/KMF2JMTtracking.html

description: This paper investigates the notion of scientific ‘excellence’ at the heart of public research policies by comparing it with the situation regarding the regional development of scientific activity in France. The case presented is based on bibliometric analysis of chemistry publications in French cities between 1985 and 2010, during which the policies of excellence were still not effective. It is asserted that the trend was towards an identical level of excellence across the country's different cities and that the dynamics of regional cities depends on them being ‘equipped’ with researchers, internationalized and specialized in emerging fields.

Universality and Scaling for the Structure Factor in Dynamic Order-Disorder Transitions

description: The universal form for the average scattering intensity from systems undergoing order-disorder transitions is found by numerical integration of the Langevin dynamics. The result is nearly identical for simulations involving two different forms of the local contribution to the free energy, supporting the idea that the Model A dynamical universality class includes a wide range of local free-energy forms. An absolute comparison with no adjustable parameters is made to the forms predicted by the theories of Ohta-Jasnow-Kawasaki and Mazenko. The numerical results are well described by the former theory, except in the cross-over region between scattering dominated by domain geometry and scattering determined by Porod's law.

description: Graph neural networks have been demonstrated as a powerful paradigm for effectively learning graph-structured data on the web and mining content from it.Current leading graph models require a large number of labeled samples for training, which unavoidably leads to overfitting in few-shot scenarios. Recent research has sought to alleviate this issue by simultaneously leveraging graph learning and meta-learning paradigms. However, these graph meta-learning models assume the availability of numerous meta-training tasks to learn transferable meta-knowledge. Such assumption may not be feasible in the real world due to the difficulty of constructing tasks and the substantial costs involved. Therefore, we propose a SiMple yet effectIve approach for graph few-shot Learning with fEwer tasks, named SMILE. We introduce a dual-level mixup strategy, encompassing both within-task and across-task mixup, to simultaneously enrich the available nodes and tasks in meta-learning. Moreover, we explicitly leverage the prior information provided by the node degrees in the graph to encode expressive node representations. Theoretically, we demonstrate that SMILE can enhance the model generalization ability. Empirically, SMILE consistently outperforms other competitive models by a large margin across all evaluated datasets with in-domain and cross-domain settings. Our anonymous code can be found here.

description: Using the linearized theory of general relativity, the gravitomagnetic analogue of the Barnett effect is derived. Further theoretical and experimental investigation is recommended, due to the expected macroscopic values of the gravitomagnetic field involved in this effect, and to the constraints which would appear on quantum theories of gravity, currently under development, in case of non detection of the predicted phenomena.

On the phonon-induced superconductivity of disordered alloys

description: A model of alloy is considered which includes both quenched disorder in the electron subsystem (``alloy'' subsystem) and electron-phonon interaction. For given approximate solution for the alloy part of the problem, which is assumed to be conserving in Baym's sense, we construct the generating functional and derive the Eliashberg-type equations which are valid to the lowest order in the adiabatic parameter.The renormalization of bare electron-phonon interaction vertices by disorder is taken into account consistently with the approximation for the alloy self-energy. For the case of exact configurational averaging the same set of equations is established within the usual T-matrix approach. We demonstrate that for any conserving approximation for the alloy part of the self-energy the Anderson's theorem holds in the case of isotropic singlet pairing provided disorder renormalizations of the electron-phonon interaction vertices are neglected. Taking account of the disorder renormalization of the electron-phonon interaction we analyze general equations qualitatively and present the expressions for $T_{c}$ for the case of weak and intermediate electron-phonon coupling. Disorder renormalizations of the logarithmic corrections to the effective coupling, which arise when the effective interaction kernel for the Cooper channel has the second energy scale, as well as the renormalization of the dilute paramagnetic impurity suppression are discussed.
