A possible common halo of the Magellanic Clouds

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

description: Recent observational and theoretical studies on the three-dimensional (3D) space motions of the Large and the Small Magellanic Clouds (LMC and SMC, respectively) have strongly suggested that the latest proper motion measurements of the Magellanic Clouds (MCs) are consistent with their orbital evolution models in which the MCs have arrived in the Galaxy quite recently for the first time. The suggested orbital models appear to be seriously inconsistent with the tidal interaction models in which the Magellanic Stream (MS) can be formed as a result of the mutual tidal interaction between the MCs and the Galaxy for the last ~2 Gyr. Based on orbital models of the MCs, we propose that if the MCs have a common diffuse dark halo with the mass larger than ~ 2 * 10^{10} M_sun, the MCs can not only have the present 3D velocities consistent with the latest proper motion measurements but also interact strongly with each other and with the Galaxy for the last 2 Gyr.These results imply that if the observed proper motions of the MCs are true ones of the centers of mass for the MCs, the common halo of the MCs would need to be considered in constructing self-consistent MS formation models. We discuss whether the origin of the possible common halo can be closely associated either with the past binary formation or with the MCs having been in a small group.

description: Following a previous proposal, lepton number is considered as the result of a spontaneously broken non-Abelian gauge $SU(2)_N$ symmetry. New fermions are added to support this new symmetry, the spontaneous breaking of which allows these new fermions to be part of the dark sector, together with the vector gauge boson which communicates between them and the usual leptons. A byproduct is a potential significant contribution to the muon anomalous magnetic moment.

Energy storage systems are increasingly taking up their pivotal role in modern, low-carbon power systems. The further deployment of this technology, however, crucially depends on the electricity and ancillary service markets in which they can participate and the rules that govern them. In this panel, a set of leading experts will discuss how energy storage systems may secure and stack revenues from near real-time balancing markets to day-ahead electricity markets to years-ahead capacity renumeration mechanisms. The focus of the panel is on how innovative mathematical models -- integrating technical, regulatory and market constraints – may facilitate energy storage owners to secure higher operating profits, integrate more renewable energy into our energy systems and facilitate the further development of this key technology.

description: We consider the identifiability problem for the parameters of series-parallel LCR circuit networks. We prove that for networks with only two classes of components (inductor-capacitor (LC), inductor-resistor (LR), and capacitor-resistor (RC)), the parameters are identifiable if and only if the number of non-monic coefficients of the constitutive equations equals the number of parameters. The notion of the "type" of the constitutive equations plays a key role in the identifiability of LC, LR, and RC networks. We also investigate the general series-parallel LCR circuits (with all three classes of components), and classify the types of constitutive equations that can arise, showing that there are 22 different types. However, we produce an example that shows that the basic notion of type that works to classify identifiability of two class networks is not sufficient to classify the identifiability of general series-parallel LCR circuits.

description: We present the first report of optical absorption spectroscopy of H$^{36}\!$Cl, a radioactive isotopologue of hydrogen chloride. We used Fourier-transform infrared spectroscopy to determine the line center wavenumbers of the fundamental rovibrational band lines P(10)-R(10) and the first overtone band lines P(1)-R(7) with total uncertainty of less than 0.0018 cm$^{-1}$ (60 MHz) and 0.007 cm$^{-1}$ (0.2 GHz), respectively, at 68 % confidence level. We also performed a rotational analysis on the bands to determine the related molecular constants. We further compared the linewidths and relative intensities of the lines to those of the stable isotopologues H$^{35}\!$Cl and H$^{37}\!$Cl. The new spectroscopic information assists in developing optical instrumentation for the detection of H$^{36}\!$Cl.

The modeling and computational requirements to represent in detail equipment and conditions to properly study stability in Microgrids (MGs) could be very onerous, requiring models and tools that restrict the types of studies that can be performed.  On the other hand, model approximations that reduce computational burden might not be sufficient to fully analyze the stability of these systems.  Therefore, this panel will focus on discussing the validity and applications of detailed and approximate component models and simulation tools for MG dynamic studies, in particular generator and grid modeling, converter models, unbalanced and balanced system conditions, dynamic and static loads, controls integrated with communication technologies, and protection systems.  Phasor vis-à-vis electromagnetic transient simulation tools for dynamic stability analyses will also be discussed, including the application of dynamic phasor and co-simulation approaches for these kinds of studies.  Finally, modeling scale-up issues as well as MG equivalent models will be examined.

description: In this paper we employ all-electron \textit{ab-initio} time-dependent density functional theory based method to calculate the long range dipole-dipole dispersion coefficient (van der Waals coefficient) $C_{6}$ of sodium atom clusters containing even number of atoms ranging from 2 to 20 atoms. The dispersion coefficients are obtained via Casimir-Polder relation. The calculations are carried out with two different exchange-correlation potentials: (i) the asymptotically correct statistical average of orbital potential (SAOP) and (ii) Vosko-Wilk-Nusair representation of exchange-correlation potential within local density approximation. A comparison with the other theoretical results has been performed. We also present the results for the static polarizabilities of sodium clusters and also compare them with other theoretical and experimental results. These comparisons reveal that the SAOP results for C_{6} and static polarizability are quite accurate and very close to the experimental results. We examine the relationship between volume of the cluster and van der Waals coefficient and find that to a very high degree of correlation C_{6} scales as square of the volume. We also present the results for van der Waals coefficient corresponding to cluster-Ar atom and cluster-N_{2} molecule interactions.

The extreme weather events in the form of deadly heat waves, devastating droughts, severe storms and ferocious wildfires  have impacted grids in various parts of the world and have, consequently, raised serious concerns in the areas of resource adequacy and grid resilience. The extensive reliance on deeper penetrations of renewable resources, such as wind and solar, in various regions is accompanied by the integration of energy storage resources and the retirement of controllable fossil-fired resources. In light of these developments, the panel aims to explore the utilization to date of the recently integrated energy storage resources in grids with associated electricity markets. The principal topics to be discussed include the nature and scope of regulatory initiatives to enable storage resource participation in electricity markets, the range of grid services provided by storage resources, the thrusts of the RTOs/ISOs/TSOs’ approaches to address regulatory requirements, the evolving role of resource aggregators and the impacts of storage participation on market outcomes. In addition, the panelists will discuss the challenges and opportunities faced by storage resource participants, aggregators, existing market players and the grid operators in the policy, regulation, market design and system and market operations areas.

Nonempirical Density Functionals Investigated for Jellium: Spin-Polarized Surfaces, Spherical Clusters, and Bulk Linear Response

description: Earlier tests show that the Tao-Perdew-Staroverov-Scuseria (TPSS) nonempirical meta-generalized gradient approximation (meta-GGA) for the exchange-correlation energy yields more accurate surface energies than the local spin density (LSD) approximation for spin-unpolarized jellium. In this study, work functions and surface energies of a jellium metal in the presence of ``internal'' and external magnetic fields are calculated with LSD, Perdew-Burke-Ernzerhof (PBE) GGA, and TPSS meta-GGA and its predecessor, the nearly nonempirical Perdew-Kurth-Zupan-Blaha (PKZB) meta-GGA, using self-consistent LSD orbitals and densities. The results show that: (i) For normal bulk densities, the surface correlation energy is the same in TPSS as in PBE, as it should be since TPSS strives to represent a self-correlation correction to PBE; (ii) Normal surface density profiles can be scaled uniformly to the low-density or strong-interaction limit, and TPSS provides an estimate for that limit that is consistent with (but probably more accurate than) other estimates; (iii) For both normal and low densities, TPSS provides the same description of surface magnetism as PBE, suggesting that these approximations may be generally equivalent for magnetism. The energies of jellium spheres with up to 106 electrons are calculated using density functionals and compared to those obtained with Diffusion Quantum Monte Carlo data, including our estimate for the fixed-node correction. Finally we calculate the linear response of bulk jellium using these density functionals, and find that not only LSD but also PBE GGA and TPSS meta-GGA yield a linear-response in good agreement with that of the Quantum Monte Carlo method, for wavevectors of the perturbing external potential up to twice the Fermi wavevector.

description: Over the last decade, there has been a respectable level of scientific interest regarding the concept of a warp drive. This is a hypothetical propulsion device that could theoretically circumvent the traditional limitations of special relativity which restricts spacecraft to sub-light velocities. Any breakthrough in this field would revolutionize space exploration and open the doorway to interstellar travel. This article discusses a novel approach to generating the warp bubble necessary for such propulsion; the mathematical details of this theory are discussed in an article published in the Journal of the British Interpanetary Society. The theory is based on some of the exciting predictions coming out of string theory and it is the aim of this article to introduce the warp drive idea from a non-mathematical perspective that should be accessible to a wide range of readers.

Effective attraction induced by repulsive interaction in a spin-transfer system

Publisher: name: arXiv
Year: 2007
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: In magnetic systems with dominating easy-plane anisotropy the magnetization can be described by an effective one dimensional equation for the in-plane angle. Re-deriving this equation in the presence of spin-transfer torques, we obtain a description that allows for a more intuitive understanding of spintronic devices' operation and can serve as a tool for finding new dynamic regimes. A surprising prediction is obtained for a planar ``spin-flip transistor'': an unstable equilibrium point can be stabilized by a current induced torque that further repels the system from that point. Stabilization by repulsion happens due to the presence of dissipative environment and requires a Gilbert damping constant that is large enough to ensure overdamped dynamics at zero current.

The use of forecasts is central to modern power system operation. As the penetration of renewables and complexity of load grow, managing forecast uncertainty has become critical to maintain economic and reliable power system operation. Probabilistic forecasts empower operators with quantitative information about uncertainty but must be integrated with other processes, policies, and regulation. This session will present and discuss recent experience developing new operational practices involving probabilistic forecasting from around the world.

description: A method of constructing of Darboux coordinates on a space that is a symplectic reduction with respect to a diagonal action of $GL(m})$ on a Cartesian product of $N$ orbits of coadjoint representation of $GL(m)$ is presented. The method gives an explicit symplectic birational isomorphism between the reduced space on the one hand and a Cartesian product of $N-3$ coadjoint orbits of dimension $m(m-1)$ on an orbit of dimension $(m-1)(m-2)$ on the other hand. In a generic case of the diagonalizable matrices it gives just the isomorphism that is birational and symplectic between some open, in a Zariski topology, domain of the reduced space and the Cartesian product of the orbits in question. The method is based on a Gauss decomposition of a matrix on a product of upper-triangular, lower-triangular and diagonal matrices. It works uniformly for the orbits formed by diagonalizable or not-diagonalizable matrices. It is elaborated for the orbits of maximal dimension that is $m(m-1)$.

Focusing on black holes with event horizon of toroidal topology, we study a simple model to understand explicitly how this thermal equilibrium is reached under Hawking evaporation. It is shown that it is possible for a large toroidal black hole to evolve into a small (but stable) one.

description: A characteristic feature of thermalized non-equilibrated matter is that, in spite of energy relaxation--equilibration, a phase memory of the way the many-body system was excited remains. As an example, we analyze data on a strong forward peaking of thermal proton yield in the Bi($γ$,p) photonuclear reaction. New analysis shows that the phase relaxation in highly-excited heavy nuclei can be 8 orders of magnitude or even much longer than the energy relaxation. We argue that thermalized non-equilibrated matter resembles a high temperature superconducting state in quantum many-body systems. We briefly present results on the time-dependent correlation function of the many-particle density fluctuations for such a superconducting state. It should be of interest to experimentally search for manifestations of thermalized non-equilibrated matter in many-body mesoscopic systems and nanostructures.

Tenets of energy justice include procedural justice, recognition justice and distributive justice.  The last justice tenet asks whether the benefits and costs of the energy system are equitably distributed. New thinking, objectives, and approaches are needed to evaluate how the electric grid can be structured to provide more or less equitable distribution of benefits.  The challenge has many parts: identifying measurable benefits and costs, recognizing which communities are underserved, evaluating their relationship to the energy system (spanning affordability, vulnerability, and reliability), and linking operation and investment decisions to futures where these conditions are changed. This panel will bring together decision makers from government and national labs to discuss the opportunities to enhance the energy justice and equity as we transition towards cleaner and sustainable energy resources.  The panel will include ongoing work in the Department of Energy to develop more technical robustness to analyzing equitable grids within grid planning and multi-objective modeling.

Many of these technologies are continuously monitoring the system utilizing artificial intelligence to identify fires or identify defective equipment. Other technologies, such as distribution fault anticipation, enable true condition-based maintenance of electric circuits including continual monitoring to assess the health of circuits. This includes early detection of failing devices by recognizing low grade arcing conditions and other failure signatures.

description: In this work, we provide a metric to calculate the most significant software security weaknesses as defined by an aggregate metric of the frequency, exploitability, and impact of related vulnerabilities. The Common Weakness Enumeration (CWE) is a well-known and used list of software security weaknesses. The CWE community publishes such an aggregate metric to calculate the `Most Dangerous Software Errors'. However, we find that the published equation highly biases frequency and almost ignores exploitability and impact in generating top lists of varying sizes. This is due to the differences in the distributions of the component metric values. To mitigate this, we linearize the frequency distribution using a double log function. We then propose a variety of other improvements, provide top lists of the most significant CWEs for 2019, provide an analysis of the identified software security weaknesses, and compare them against previously published top lists.

description: This review article provides an overview of recent work in the modeling and analysis of recurrent events arising in engineering, reliability, public health, biomedicine and other areas. Recurrent event modeling possesses unique facets making it different and more difficult to handle than single event settings. For instance, the impact of an increasing number of event occurrences needs to be taken into account, the effects of covariates should be considered, potential association among the interevent times within a unit cannot be ignored, and the effects of performed interventions after each event occurrence need to be factored in. A recent general class of models for recurrent events which simultaneously accommodates these aspects is described. Statistical inference methods for this class of models are presented and illustrated through applications to real data sets. Some existing open research problems are described.

The energy revolution in Europe places new requirements on the transmission grid. If it comes to large scale wind power integration in the north of Europe, as well as bulk solar power production in south, long distance bulk power transmission becomes integral part of an entirely new power system where new controllable devices will operate to make transmission smarter and more efficient. In the last consequence, a new network layer based on HVDC technology may arise which is referred to as an overlay grid in Europe. This session is about activities carried out in Europe and focusing offshore HVDC grids, recent HVDC projects in Europe as well as on meshed HVDC grids in terms of visions, technology and operational issues.

High Voltage DC Circuit Breakers have seen rapid technology advances recently, in terms of improved performance and lowering costs. Multiple 500kV DC CB units have been installed in Zhangbei project and 3 different technologies have been tested at high voltage at an independent laboratory in Europe. There is significant ongoing research worldwide with some laboratory prototypes reporting very fast insertion of counter voltage, in the timeframe below 1ms. Other technologies, with proven track record of cost-effectiveness at medium DC voltage levels are now upscaled to High DC transmission voltages. The DC grid protection strategy is also evolving, in response to DC CB advances and operating experience. CIGRE is completing 2nd working group on DC CB topic, and as IEEE and IEC have begun work on DC CB standard development, it is important to facilitate two-way discussion between professional community  and key experts from manufacturers and research centers.
High Voltage DC Circuit Breakers have seen rapid technology advances recently, in terms of improved performance and lowering costs. Multiple 500kV DC CB units have been installed in Zhangbei project and 3 different technologies have been tested at high voltage at an independent laboratory in Europe. There is significant ongoing research worldwide with some laboratory prototypes reporting very fast insertion of counter voltage, in the timeframe below 1ms. Other technologies, with proven track record of cost-effectiveness at medium DC voltage levels are now upscaled to High DC transmission voltages.

description: Soil bulk density affects water storage, water and nutrient movement, and plant root activity in the soil profile. Its measurement is difficult in field conditions. Vibration-induced conductivity fluctuation was investigated to quantify soil bulk density with possible field applications in the future. The AC electrical conductivity of soil was measured using a pair of blade-like electrodes while exposing the soil to periodic vibration. The blades were positioned longitudinally and transversally to the direction of the induced vibration to enable the calculation of a normalized index. The normalized index was expected to provide data independent from the vibration strength and to reduce the effect of soil salinity and water content. The experiment was conducted on natural and salinized fine sand at two moisture conditions and four bulk densities. The blade-shaped electrodes improved electrode-soil contact compared to cylindrical electrodes, and thereby, reduced measurement noise. Simulations on a simplified resistor lattice indicate that the transversal effect increases as soil bulk density decreases. Measurement of dry sand showed a negative correlation between the normalized conductivity fluctuation and soil bulk density for both longitudinal and transversal settings. The decrease in the transversal signal was smaller than expected. The wet natural and salinized soils performed very similarly as hypothesized, but their normalized VICOF response was not significant to bulk density changes.

description: This work presents a new approach to unsupervised abstractive summarization based on maximizing a combination of coverage and fluency for a given length constraint. It introduces a novel method that encourages the inclusion of key terms from the original document into the summary: key terms are masked out of the original document and must be filled in by a coverage model using the current generated summary. A novel unsupervised training procedure leverages this coverage model along with a fluency model to generate and score summaries. When tested on popular news summarization datasets, the method outperforms previous unsupervised methods by more than 2 R-1 points, and approaches results of competitive supervised methods. Our model attains higher levels of abstraction with copied passages roughly two times shorter than prior work, and learns to compress and merge sentences without supervision.

The climate continues to change, and the reported socioeconomic impacts demonstrate the vulnerability of populations to current weather and climate events. Crucial to tackling this crisis is to decarbonize the worlds energy system and shift the global energy demand from fossil fuels to a low carbon supply. This Super Session will address the challenges around net-zero GHG emissions goals, the pathways to decarbonizing the electric sector, and the present and future role of engineering in energy sustainability. Panelists from around the world and multiple sectors will converge to outline the critical actions needed to accelerate and smooth the clean energy transition.

description: Zero-field muon-spin relaxation measurements of the frustrated triangular quantum magnet AgNiO2 are consistent with a model of charge disproportionation that has been advanced to explain the structural and magnetic properties of this compound. Below an ordering temperature of T_N=19.9(2) K we observe six distinct muon precession frequencies, due to the magnetic order, which can be accounted for with a model describing the probable muon sites. The precession frequencies show an unusual temperature evolution which is suggestive of the separate evolution of two opposing magnetic sublattices.

description: We observed the X-ray binaries CirX-1, ScoX-1, GRS 1915+105, GX13+1, and CygX-1 with the Atacama Large Millimeter/submillimeter Array (ALMA). Unresolved continuum emission is found at the positions of all the sources at a frequency of 92 GHz, with flux densities ranging between 0.8 and 10 mJy/beam. In all cases the emission can be associated with jets that have been extensively observed at lower frequencies. We searched for line emission from H$α$ recombination, SiO,H2O, and CH3OH at the positions of all the sources and, for CirX-1 and CygX-1, also at regions where shocks associated with an interaction between the jet and the interstellar medium had previously been observed. The search did not yield any significant detection, resulting in 3$σ$ upper limits between 0.65 and 3.7 K km s$^{-1}$ for the existence of line emission in these regions. In contrast, we detected spatially unresolved SiO emission in the field of view of GX13+1, and we tentatively associate this emission with a SiO maser in a potential young stellar object or evolved star. We also found spatially extended line emission at two additional sites in the field of view of GX13+1 that we tentatively associate with emission from SO and CH3OH; we speculate that it may be associated with a star-forming region, but again we cannot rule out alternative origins such as emission from evolved stars.

description: Heating under periodic driving is a generic nonequilibrium phenomenon, and it is a challenging problem in nonequilibrium statistical physics to derive a quantitatively accurate heating rate. In this work, we provide a simple formula on the heating rate under fast and strong periodic driving in classical and quantum many-body systems. The key idea behind the formula is constructing a time-dependent dressed Hamiltonian by moving to a rotating frame, which is found by a truncation of the high-frequency expansion of the micromotion operator, and applying the linear-response theory. It is confirmed for specific classical and quantum models that the second-order truncation of the high-frequency expansion yields quantitatively accurate heating rates beyond the linear-response regime. Our result implies that the information on heating dynamics is encoded in the first few terms of the high-frequency expansion, although heating is often associated with an asymptotically divergent behavior of the high-frequency expansion.
