Eccentricity evolution of giant planet orbits due to circumstellar disk torques

description: The extrasolar planets discovered to date possess unexpected orbital elements. Most orbit their host stars with larger eccentricities and smaller semi-major axes than similarly sized planets in our own solar system do. It is generally agreed that the interaction between giant planets and circumstellar disks (Type II migration) drives these planets inward to small radii, but the effect of these same disks on orbital eccentricity, e, is controversial. Several recent analytic calculations suggest that disk-planet interactions can excite eccentricity, while numerical studies generally produce eccentricity damping. This paper addresses this controversy using a quasi-analytic approach, drawing on several preceding analytic studies. This work refines the current treatment of eccentricity evolution by removing several approximations from the calculation of disk torques. We encounter neither uniform damping nor uniform excitation of orbital eccentricity, but rather a function de/dt that varies in both sign and magnitude depending on eccentricity and other solar system properties. Most significantly, we find that for every combination of disk and planet properties investigated herein, corotation torques produce negative values of de/dt for some range in e within the interval [0.1, 0.5]. If corotation torques are saturated, this region of eccentricity damping disappears, and excitation occurs on a short timescale of less than 0.08 Myr. Thus, our study does not produce eccentricity excitation on a timescale of a few Myr -- we obtain either eccentricity excitation on a short time scale, or eccentricity damping on a longer time scale. Finally, we discuss the implications of this result for producing the observed range in extrasolar planet eccentricity.

description: N-body + hydrodynamical simulations of the formation and evolution of galaxy groups and clusters in a LambdaCDM cosmology are used in order to follow the building-up of the colour-magnitude relation in two clusters and in 12 groups. We have found that galaxies, starting from the more massive, move to the Red Sequence (RS) as they get aged over times and eventually set upon a ``dead sequence'' (DS) once they have stopped their bulk star formation activity. Fainter galaxies keep having significant star formation out to very recent epochs and lie broader around the RS. Environment plays a role as galaxies in groups and cluster outskirts hold star formation activity longer than the central cluster regions. However galaxies experiencing infall from the outskirts to the central parts keep star formation on until they settle on to the DS of the core galaxies. Merging contributes to mass assembly until z~1, after which major events only involve the brightest cluster galaxies. The emerging scenario is that the evolution of the colour-magnitude properties of galaxies within the hierarchical framework is mainly driven by star formation activity during dark matter halos assembly. Galaxies progressively quenching their star formation settle to a very sharp ``red and dead'' sequence, which turns out to be universal, its slope and scatter being almost independent of the redshift (since at least z~1.5) and environment. Differently from the DS, the operatively defined RS evolves more evidently with z, the epoch when it changes its slope being closely corresponding to that at which the passive galaxies population takes over the star forming one: this goes from z~1 in clusters down to 0.4 in normal groups.

description: We provide high-precision predictions for muon-pair and tau-pair productions in a photon-photon collision by considering a complete set of one-loop-level scattering amplitudes, i.e., electroweak (EW) corrections together with soft and hard QED radiation. Accordingly, we present a detailed numerical discussion with particular emphasis on the pure QED corrections as well as genuinely weak corrections. The effects of angular and initial beam polarisation distributions on production rates are also discussed. An improvement is observed by a factor of two with oppositely polarized photons. Our results indicate that the one-loop EW radiative corrections enhance the Born cross section and the total relative correction is typically about ten percent for both production channels. It appears that the full EW corrections to $γγ\to \ell^- \ell^+$ are required to match a percent level accuracy.

description: The properties of black-hole and neutron-star binaries are extracted from gravitational-wave signals using Bayesian inference. This involves evaluating a multi-dimensional posterior probability function with stochastic sampling. The marginal probability density distributions from which the samples are drawn are usually interpolated with kernel density estimators. Since most post-processing analysis within the field is based on these parameter estimation products, interpolation accuracy of the marginals is essential. In this work, we propose a new method combining histograms and Gaussian Processes as an alternative technique to fit arbitrary combinations of samples from the source parameters. This method comes with several advantages such as flexible interpolation of non-Gaussian correlations, Bayesian estimate of uncertainty, and efficient re-sampling with Hamiltonian Monte Carlo.

description: The Persistence of Myth as Symbolic Form collects papers from an international conference organised by the Centre for Intercultural Studies at the University of Glasgow (16-18.9.2005). The volume, edited by Paul Bishop and Roger H. Stephenson, explores the potential of Ernst Cassirer’s concept of myth for contemporary issues in cultural theory and investigates the scope of influences essential to his thinking. Drawing from philosophical, historical, anthropological, literary, aesthetic, scientific and political perspectives, the authors home in on the central question: in what ways can knowledge productively address the irrefutable power of myth?

description: The recent star formation history in the Cygnus region is studied using 5 clusters (IC 4996, NGC 6910, Berkeley 87, Biurakan 2 and Berkeley 86). The optical data from the literature are combined with the 2MASS data to identify the pre-main sequence (pre-MS) stars as stars with near IR excess. We identified 93 pre-MS stars and 9 stars with H$_α$ emission spectra. The identified pre-MS stars are used to estimate the turn-on age of the clusters. The duration of star formation was estimated as the difference between the turn-on and the turn-off age. We find that, NGC 6910 and IC 4996 have been forming stars continuously for the last 6 -- 7 Myr, Berkeley 86 and Biurakan 2 for 5 Myr and Berkeley 87 for the last 2 Myr. This indicates that the Cygnus region has been actively forming stars for the last 7 Myr, depending on the location. 9 emission line stars were identified in 4 clusters, using slit-less spectra (Be 87 - 4 stars; Be 86 - 2 stars, NGC 6910 - 2 stars and IC 4996 - 1 star). The individual spectra were obtained and analysed to estimate stellar as well as disk properties. All the emission stars are in the MS, well below the turn-off, in the core hydrogen burning phase. These stars are likely to be Classical Be (CBe) stars. Thus CBe phenomenon can be found in very young MS stars which are just a few (2 -- 7) Myrs old. This is an indication that CBe phenomenon need not be an evolutionary effect.

This panel session will focus on providing a general overview of the IEEE 1250 document along with background and history.  Historically, IEEE 1250 was written as a guide for protecting sensitive equipment to momentary voltage disturbances.  Over the years it has evolved into a more all-encompassing document covering all areas of power quality in a more general fashion with the intent of pointing users to other related standards that cover each area in more depth.  Those areas of voltage quality include voltage regulation, voltage imbalance, harmonic distortion, voltage fluctuations (e.g. flicker and RVC), voltage sags, interruptions and transients.  IEEE 1250 also contains guidance on susceptibility of power system loads and voltage quality improvement for end users.

The spectral weight of the lowest energy state found to be enhanced in the bulk sensitive Ni 2p core-level PES. A configuration-interaction model including the bound state screening has shown significant agreement with the core-level spectra, and the off and on-resonance VB spectra. These results identify the lowest energy state in core-level and VB-PES as the Zhang-Rice doublet bound state, consistent with the spin-fermion model and recent ab initio calculation with dynamical mean-field theory (LDA + DMFT).

New Approaches to Risk Management for Power Systems

Publisher: name: IEEE
Year: 2022

Optimal utilization of all grid assets requires a fundamental shift in grid management rooted in an understanding of asset risk and system risk. Existing management practices were designed for a grid consisting of and fully reliant on conventional generation assets. Present operational and planning practices do not acknowledge or leverage the true capabilities and associated challenges of emerging assets. A novel risk-driven paradigm will allow emerging assets to be trusted and relied upon to provide the critical products and services necessary to maintain an efficient and reliable grid, thereby breaking the persistent reliance on conventional generation technologies. ARPA-E’s PERFORM program (Performance-based Energy Resource Feedback, Optimization, and Risk Management) seeks to develop innovative management systems that represent the relative delivery risk of each asset and balance the collective risk of all assets across the grid. A risk-driven paradigm allows operators to: (i) fully understand the true likelihood of maintaining a supply-demand balance and system reliability, (ii) optimally manage the system, and (iii) assess the true value of essential reliability services. This paradigm shift is critical for all power systems and is essential for grids with high levels of stochastic resources. Projects will propose methods to quantify and manage risk at the asset level and at the system level.

description: We examine four high resolution reflection grating spectrometers (RGS) spectra of the February 2009 outburst of the luminous recurrent nova LMC 2009a. They were very complex and rich in intricate absorption and emission features. The continuum was consistent with a dominant component originating in the atmosphere of a shell burning white dwarf (WD) with peak effective temperature between 810,000 K and a million K, and mass in the 1.2-1.4 M$_\odot$ range. A moderate blue shift of the absorption features of a few hundred km s$^{-1}$ can be explained with a residual nova wind depleting the WD surface at a rate of about 10$^{-8}$ M$_\odot$ yr$^{-1}$. The emission spectrum seems to be due to both photoionization and shock ionization in the ejecta. The supersoft X-ray flux was irregularly variable on time scales of hours, with decreasing amplitude of the variability. We find that both the period and the amplitude of another, already known 33.3 s modulation, varied within timescales of hours. We compared N LMC 2009a with other Magellanic Clouds novae, including 4 serendipitously discovered as supersoft X-ray sources (SSS) among 13 observed within 16 years after the eruption. The new detected targets were much less luminous than expected: we suggest that they were partially obscured by the accretion disk. Lack of SSS detections in the Magellanic Clouds novae more than 5.5 years after the eruption constrains the average duration of the nuclear burning phase.

description: We study the density structures of planetary nebulae implied by four diagnostics that sample different regions within the nebulae: [S II] $\lambda6716/\lambda6731$, [O II] $\lambda3726/\lambda3729$, [Cl III] $\lambda5518/\lambda5538$, and [Ar IV] $\lambda4711/\lambda4740$. We use a sample of 46 objects with deep spectra that allow the calculation of the electron density from these four diagnostics, and explore the impact that different atomic data have on the results. We compare the observational results with those obtained from photoionization models characterized by three different density structures. We conclude that the atomic data used in the calculations of electron density fully determine the density structures that are derived for the objects. We illustrate this by selecting three combinations of atomic data that lead to observational results that are compatible with each of the three different density structures explored with the models.

Towards Understanding the Origin and Evolution of Ultra-Diffuse Galaxies
Creators: name: van der Burg, Remco
Publisher: name: Zenodo
Year: 2019

description: Recent observations of Ultra-Diffuse Galaxies (UDGs, which have the luminosities of dwarfs but sizes of giant galaxies) have picked up a lot of attention by the community. They are routinely found in clusters, while one would naively expect them to be easily disrupted by tidal interactions in such over-dense environments. Indeed, current theoretical models can produce UDGs as efficiently in the field. However, observational constraints on whether the formation of UDGs is -somehow- affected by cluster and group environments are currently lacking. I will summarise recent developments that address this question, results which are based on the synergy between the GAMA@AAO and KiDS@ESO surveys. Surprisingly, these show that clusters indeed host a surprisingly high relative number of UDGs compared to lower-density environments. I will discuss implications and future prospects (especially regarding measurements of their total masses) to learn more about the properties and formation histories of these elusive galaxies.
Land, community, corporation : intercultural correlation between ideas of land in Dene and Inuit tradition and in Canadian law
Creators: name: Piddocke, Stuart
Publisher: name: University of British Columbia
Year: 2010

description: The present enquiry is a study of specific social possibilities in a culture-contact situation, namely the encounter of the Dene and Inuit of the Northwest Territories with Canadian society; and shows how by analyzing the basic content of two traditions in contact with one another, the possibilities for mutual adjustment of one tradition to the other, or the lack of such possibilities, may be logically derived from that content. The study also uses the perspective of cultural ecology to devise and demonstrate a way in which any system of land-tenure may be compared with any other, without the concepts of one system being imposed upon the other. The particular problem of the enquiry is to compare the traditional ideas of land and land-tenure among Dene and Inuit with the ideas of land and land-tenure in Canadian law; and to discover a way whereby the Dene and Inuit may use the concepts of the dominant Canadian system to preserve their own traditional ways of holding land. The analysis begins by outlining the cultural ecosystem of each people, their basic modes of subsistence, the resources used, the kinds of technical operations applied to those resources, the work organization, and relevant parts of social organization and world-view. Then, in order, the idea of land which the people appear to be following, the kinds of land-rights and principles of land-holding recognized by the" people, and the kinds of "persons" who may hold land-rights, are described. The systems are then compared in order to discover the possibilities for "reconciliation". The enquiry concludes that the basic premises and characters of the Dene and Inuit systems of land-tenure are fundamentally irreconcilable with those of Canadian real property law, but that the Dene and Inuit systems can be encapsulated within the dominant Canadian system by means of the Community Land-Holding Corporation (CLHC). The CLHC as proposed in this enquiry would allow the members of a community to hold land among themselves according to their own rules, while the corporation holds the land of the whole community against outsiders according to the principles of Canadian law.

description: Within the idealized scheme of a 1-dimensional Frenkel-Kontorova-like model, a special "quantized" sliding state was found for a solid lubricant confined between two periodic layers [PRL 97, 056101 (2006)]. This state, characterized by a nontrivial geometrically fixed ratio of the mean lubricant drift velocity and the externally imposed translational velocity v_ext, was understood as due to the kinks (or solitons), formed by the lubricant due to incommensuracy with one of the substrates, pinning to the other sliding substrate. A quantized sliding state of the same nature is demonstrated here for a substantially less idealized 2-dimensional model, where atoms are allowed to move perpendicularly to the sliding direction and interact via Lennard-Jones potentials. Clear evidence for quantized sliding at finite temperature is provided, even with a confined solid lubricant composed of multiple (up to 6) lubricant layers. Characteristic backward lubricant motion produced by the presence of "anti-kinks" is also shown in this more realistic context.

REMARK
The male of E. laevis was not known, and the examined specimen fits weil to the described as E. knuppenburgensis Altherr in Altherr & Delamarre Deboutteville, 1972. Altherr mentioned ten supplements, which is not considered distinctly different From nine observed herein. Therefore, the two species are synonymized. Their possible identity was already suggested by Altherr.

description: About a century ago, Born proposed a possible matter of state, ferroelectric fluid, might exist if the dipole moment is strong enough. The experimental realisation of such states needs magnifying molecular polar nature to macroscopic scales in liquids. Here, we report on the discovery of a novel chiral liquid matter state, dubbed chiral ferronematic, stabilized by the local ferroelectric ordering coupled to the chiral helicity. It carries the polar vector rotating helically, corresponding to a helieletric structure, analogous to the magnetic counterpart of helimagnet. The state can be retained down to room-temperature and demonstrates gigantic dielectric and nonlinear optical responses. The novel matter state opens a new chapter for exploring the material space of the diverse ferroelectric liquids.

description: Differentiation has widespread applications, particularly in image processing for edge detection. Significant advances have been made in using nanophotonic structures and metamaterials to perform such operations. In particular, a recent work demonstrated a topological differentiator in which the transfer function exhibits a topological charge, making the differentiation operation robust to variation of operating conditions. The demonstrated topological differentiator, however, operates in the reflection mode at off-normal incidence and is difficult to integrate into compact imaging systems. In this work, we design a topological differentiator that operates isotropically in transmission mode at normal incidence. The device exhibits an optical transfer function with a symmetry-protected, topological charge of $\pm 2$ and performs second-order differentiation. Our work points to the potential of harnessing topological concepts for optical computing applications.

There are several plans for interconnected power grids using high-voltage direct current (HVdc) transmission networks. As we explore multiple scenarios of using HVdc to interconnect power grids, integrate renewables, share resources across asynchronous interconnections and in different time zones, among others, it would be valuable to understand the different value propositions considered for utilizing HVdc systems. It would also help to understand the recent advances in HVdc technologies (including advanced control systems, protection systems, among others) and different technical values identified from HVdc technologies. Finally, the session will also identify the gaps (like in breakers, voltage-source converters, among others) that will need to be addressed to enable further presence of HVdc technologies in the power grid.

description: We discuss the effect of slow phase relaxation and the spin off-diagonal $S$-matrix correlations on the cross section energy oscillations and the time evolution of the highly excited intermediate systems formed in complex collisions. Such deformed intermediate complexes with strongly overlapping resonances can be formed in heavy ion collisions, bimolecular chemical reactions and atomic cluster collisions. The effects of quasiperiodic energy dependence of the cross sections, coherent rotation of the hyperdeformed $\simeq (3:1)$ intermediate complex, Schrödinger cat states and quantum-classical transition are studied for $^{24}$Mg+$^{28}$Si heavy ion scattering.

The stellar content of the Hamburg/ESO survey. IV. Selection of candidate metal-poor stars

description: We present the quantitative methods used for selecting candidate metal-poor stars in the Hamburg/ESO objective-prism survey (HES). The selection is based on the strength of the Ca II K line, B-V colors (both measured directly from the digital HES spectra), as well as J-K colors from the 2 Micron All Sky Survey. The KP index for Ca II K can be measured from the HES spectra with an accuracy of 1.0 Angstrom, and a calibration of the HES B-V colors, using CCD photometry, yields a 1-sigma uncertainty of 0.07 mag for stars in the color range 0.3 < B-V < 1.4. These accuracies make it possible to reliably reject stars with [Fe/H] > -2.0 without sacrificing completeness at the lowest metallicities. A test of the selection using 1121 stars of the HK survey of Beers, Preston, and Shectman present on HES plates suggests that the completeness at [Fe/H] < -3.5 is close to 100% and that, at the same time, the contamination of the candidate sample with false positives is low: 50% of all stars with [Fe/H] > -2.5 and 97% of all stars with [Fe/H] > -2.0 are rejected. The selection was applied to 379 HES fields, covering a nominal area of 8853 square degrees of the southern high Galactic latitude sky. The candidate sample consists of 20,271 stars in the magnitude range 10 < B < 18. A comparison of the magnitude distribution with that of the HK survey shows that the magnitude limit of the HES sample is about 2 mag fainter. Taking the overlap of the sky areas covered by both surveys into account, it follows that the survey volume for metal-poor stars has been increased by the HES by about a factor of 10 with respect to the HK survey. We have already identified several very rare objects with the HES, including, e.g., the three most heavy-element deficient stars currently known.

On Compressed Sensing of Binary Signals for the Unsourced Random Access Channel

description: Motivated by applications in unsourced random access, this paper develops a novel scheme for the problem of compressed sensing of binary signals. In this problem, the goal is to design a sensing matrix $A$ and a recovery algorithm, such that the sparse binary vector $\mathbf{x}$ can be recovered reliably from the measurements $\mathbf{y}=A\mathbf{x}+σ\mathbf{z}$, where $\mathbf{z}$ is additive white Gaussian noise. We propose to design $A$ as a parity check matrix of a low-density parity-check code (LDPC), and to recover $\mathbf{x}$ from the measurements $\mathbf{y}$ using a Markov chain Monte Carlo algorithm, which runs relatively fast due to the sparse structure of $A$. The performance of our scheme is comparable to state-of-the-art schemes, which use dense sensing matrices, while enjoying the advantages of using a sparse sensing matrix.

description: We studied complex lasing pattern formations in a thin-slice solid-state laser with wide-aperture laser-diode end-pumping. Radial and rectangular vortex arrays were found to be formed in a controlled fashion with symmetric and asymmetric pump beam profiles, respectively. Most of these vortices exhibited single-frequency oscillations arising from a spontaneous process of transverse mode locking of nearly degenerate modes assisted by the laser nonlinearity. Single-frequency rectangular array beams consisting of a large number of vortices, e.g., closely packed 36 or 46 vortex pixels, were generated, originating from Ince-Gaussian modes excited by the asymmetric pumping.
