Subjects: subject: Atomic Physics (physics.atom-ph)

description: We explore the dependence of the double ionization of the He atom on the frequency of a strong laser field while keeping the ponderomotive energy constant. As we increase the frequency we find that the remarkable "finger-like" structure for high momenta recently found for $ω=0.055$ a.u. \cite{Staudte, Rudenko} persists for higher frequencies. At the same time, at $ω=0.187$ a.u. a new X-shape structure emerges for small momenta that prevails in the correlated momenta distribution. The role of this structure as a signature of the frequency dependence of non-sequential double ionization is discussed.

Lithoporella melobesioides (Foslie) Foslie, 1909: 59.
DESCRIPTION
Encrusting growth form, forming either single thallus or multiple overgrowth, primigenous filaments composed of large vertically elongated cells forming unistratose layers, thallus dimerous, cells of the VC measuring 12 to 18 µm in length and 22 to 38 µm in diameter, postigenous filaments arise from the primigenous filaments and mostly occur around the conceptacles. Cells of the postigenous filaments measure 16 to 32 µm in length and 8 to 20 µm in diameter. Conceptacles are uniporate, measuring 174 to 400 µm in diameter and 71 to 140 µm in height (Table 1).
REMARKS
According to Woelkerling (1988) the status of most of the species of Lithoporella is uncertain, though Lithoporella melobesioides has been described as fossils from the Palaeogene and Neogene sediments from different parts of the world. Our observations confirm the description provided byRasser & Piller (1999) for the late Eocene material of the Austrian Molasse zone. The earliest record of the taxon is from the late Jurassic (Aguirre et al. 2000). In India, Lithoporella melobesioides has been recorded earlier from the late Eocene (Sarma et al. 2014), Miocene to Holocene (Kundal et al. 2011, 2016) (Table 2).

Measuring Outer Disk Warps with Optical Spectroscopy

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Warps in the outer gaseous disks of galaxies are a ubiquitous phenomenon, but it is unclear what generates them. One theory is that warps are generated internally through spontaneous bending instabilities. Other theories suggest that they result from the interaction of the outer disk with accreting extragalactic material. In this case, we expect to find cases where the circular velocity of the warp gas is poorly correlated with the rotational velocity of the galaxy disk at the same radius. Optical spectroscopy presents itself as an interesting alternative to 21-cm observations for testing this prediction, because (i) separating the kinematics of the warp from those of the disk requires a spatial resolution that is higher than what is achieved at 21 cm at low HI column density; (ii) optical spectroscopy also provides important information on star formation rates, gas excitation, and chemical abundances, which provide clues to the origin of the gas in warps. We present here preliminary results of a study of the kinematics of gas in the outer-disk warps of seven edge-on galaxies, using multi-hour VLT/FORS2 spectroscopy.

The transition from synchronous generation based to converter dominated power grids has raised the awareness of need for comprehensive grid support. As a result, grid forming feature is emerging as a requirement to power converters in different applications, such as HVDC, FACTS, microgrids, grid interties, etc. A grid forming converter, in general, denotes a converter with the capability to control the terminal voltage frequency and amplitude to form the grid voltage, thus being able to provide steady-state and/or transient grid support, i.e. inertia enhancement, frequency response, voltage control and system strength. The grid forming feature is deemed as essential for the grid resiliency, stability and security. However, the implementation, performance requirements, system impact and testing/assessment methodology are not yet standardized and may differ between applications. This panel discusses research and development of GFCs including: - Progress in standardization of grid forming control - Advances in research and development  - Test method and guideline for grid forming converters - Potential impact of GFC on power system operation and protection

Predation, dispersal and weather in an orchard mite system
Creators: name: Johnson, Dan Lloyd
Publisher: name: University of British Columbia
Year: 2010

description: The history, management and ecology of the European red mite, Panonvchus ulmi Koch, and two important phytoseiid predators, Typhiodromus caudiglans Schuster and Typhiodromus occidentalis Nesbitt were reviewed. The roles and interactions of dispersal, predation and weather in the orchard mite system were examined. Field experiments in an apple orchard with well-established phytoseiid and European red mite (ERM) populations showed that Typhiodromus rarely move among or between trees and the ground cover, either by air or via the trunk. They were incapable, within a single season, of repopulating trees from which phytoseiids had been removed by early-season carbaryl application, even though these trees supported high prey populations and were interspersed among unsprayed trees well-populated with Typhiodromus and the ERM. Large numbers of sticky traps captured very few aerially dispersing phytoseiids. In contrast, their ERM prey actively dispersed within trees and throughout the orchard. Mite densities were uncorrelated with leaf chlorophyll content; within-tree dispersal was not directly determined by leaf condition. Adult females were greatly over-represented in aerially-dispersing ERM emigrants in comparison with populations on the apple trees. No density threshold effect on ERM dispersal was discernible on a per-tree basis. Aerial dispersal was extensive and appeared to depend on the weather more mites disperse on warm and calm days than on cool or windy days. ERM dispersal via the tree trunk was minimal and the presence of weeds resulted in only a slight increase in ERM density on the trees. The phytoseiids affected the ERM by reducing population densities, by reducing the proportion of immatures, and by decreasing the degree of prey aggregation (as represented by frequency distribution of leaf counts). The consequences of low predator dispersal and high prey dispersal in a weather-dependent system are discussed. Results of computer simulation of the development, predation, and dispersal are presented. Dispersal (immigration and emigration) allow the phytoseiid populations in the single-tree model to persist and control the ERM. In simulations of the interaction of Typhlodromus with the ERM, the interaction of dispersal and temperature-related processes is strong and non-linear, and may operate through several processes.

Historically, distribution system analysis have been able to assume constant frequency, with limited need for dynamic analysis, e.g., voltage sags due to motor starting. This assumption loses validity as more grid-forming inverters, distributed storage and microgrids appear on distribution systems. The panel will present new requirements, tools and examples for dynamic analysis on the distribution system.

Coordinated Damping Control Design for Power System With Multiple Virtual Synchronous Generators Based on Prony Method

Year: 2021

This paper has investigated the impact of multiple virtual synchronous generators on power system low frequency oscillations.
With more renewables integrated into power grids, the systems are being transformed into low inertia power electronic dominated systems. In this situation, the virtual synchronous generator (VSG) control strategy was proposed to deal with insufficient inertia challenge caused by the reduction of synchronous generation. However, as the VSG control method emulates the dynamic behavior of traditional synchronous machines, the interaction between multiple VSG controllers and synchronous generators (SGs) may cause low-frequency oscillation similar to that caused by the interaction between multiple SGs. This paper reveals that the system low-frequency oscillatory modes are affected by multiple VSGs. Then Prony analysis is utilized to extract the system mode information which will be subsequently used for VSG controller design, and a decentralized sequential coordinated method is proposed to design the supplementary damping controller (SDC) for multiple VSGs. The system low-frequency oscillation is first analyzed based on a modified two-area system with a linearized state-space model, and a further case study based on a revised New England 10-machine 39-bus system is used to demonstrate the effectiveness of the proposed coordinated method for multiple VSGs.

description: We use functional Bethe Ansatz equations to calculate the cumulants of the total current in the partially asymmetric exclusion process. We recover known formulas for the first two cumulants (mean value of the current and diffusion constant) and obtain an explicit finite size formula for the third cumulant. The expression for the third cumulant takes a simple integral form in the limit where the asymmetry scales as the inverse of the square root of the size of the system, which corresponds to a natural separation between weak and strong asymmetry.

PELS Webinar Slides
Abstract: The concept of wireless power is originated from Heinrich Hertz and well known by the work of Nikola Tesla. Nowadays the inductive-based wireless power has already been used to charge biomedical implants, consumer electronics, and even electric vehicles.

Accurate modeling a wireless power transfer system is a challenge due to the nonlinear magnetic materials used in the system and the complex magnetic effects. In order to address the challenge, Ansys provides finite element analysis in Maxwell. In this webinar, the general topics such magnetic analysis of the coil structures and circuit analysis of the wireless power transfer system will be introduced. Furthermore, the advanced topics on power and efficiency analysis, coil design optimization, coil modeling with existing permanent magnets, and thermal analysis will be presented.

description: A theory of higher rank multiresolution analysis is given in the setting of abelian multiscalings. This theory enables the construction, from a higher rank MRA, of finite wavelet sets whose multidilations have translates forming an orthonormal basis in $L^2(\bR^d)$. While tensor products of uniscaled MRAs provide simple examples we construct many nonseparable higher rank wavelets. In particular we construct Latin square wavelets as rank 2 variants of Haar wavelets. Also we construct nonseparable scaling functions for rank 2 variants of Meyer wavelet scaling functions, and we construct the associated nonseparable wavelets with compactly supported Fourier transforms. On the other hand we show that compactly supported scaling functions for biscaled MRAs are necessarily separable.

description: We quantify the detectability of stellar Milky Way satellites in the Sloan Digital Sky Survey (SDSS) Data Release 5. We show that the effective search volumes for the recently discovered SDSS--satellites depend strongly on their luminosity, with their maximum distance, $D_{max}$, substantially smaller than the Milky Way halo's virial radius. Calculating the maximum accessible volume, $V_{max}$, for all faint detected satellites, allows the calculation of the luminosity function for Milky Way satellite galaxies, accounting quantitatively for their detectability. We find that the number density of satellite galaxies continues to rise towards low luminosities, but may flatten at $M_V \sim -5$; within the uncertainties, the luminosity function can be described by a single power law $dN/dM_{V}= 10 \times 10^{0.1 (M_V+5)}$, spanning luminosities from $M_V=-2$ all the way to the luminosity of the Large Magellanic Cloud. Comparing these results to several semi-analytic galaxy formation models, we find that their predictions differ significantly from the data: either the shape of the luminosity function, or the surface brightness distributions of the models, do not match.

Advancements on transactive energy systems (TES) are providing platforms for coordinated participation of distribute energy resources (DERs “ including flexible loads) for efficient grid operation using market-based mechanisms. Each DER has an intelligent agent that manages local goals and is capable of making its own decisions. However, the managements of vast numbers of such agents requires formal mechanisms and appropriate use of design methodologies. This panel intends to provide theoretical foundation, design criterion, and existing platforms for the integration of vast numbers of MAS in TES setting. Moreover, the panel will cover ongoing simulations effort with the vast numbers of transactive agents and their control and coordination approaches.

The corresponding parameter P_c(X) is increased by up to 2% with respect to the pure QCD estimate to P_c(X) = 0.372 +- 0.015 for m_c(m_c)= (1.286 +- 0.013) GeV, alphas(M_Z) = 0.1176 +- 0.0020 and |V_us| = 0.2255. For the branching ratio we find B(K+ -> pi+ nu nu-bar) = (8.5 +- 0.7)*10^{-11}, where the quoted uncertainty is dominated by the CKM elements.

VSC HVDC converter stations are very complex systems that are able to provide a highly dynamic response to system events. These converters make use of multiple dedicated control loops and protection systems to allow for this dynamic response. To protect the vendor's IP, only proprietary black (or grey) box software models are available, limiting the ability of the HVDC owner/consultant to obtain a full image of the behavior of the equipment and its interaction with other equipment. The inability to model the response under all eventualities when using offline EMT type software leads to uncertainty on the actual behavior of the HVDC equipment. In order to reduce risks, many system operators and prospective HVDC system owners revert to the use of dedicated replica (hardware) models of the converters connected to a (real-time) simulator to perform a broad range of in depth studies. This panel discusses the pros and cons of this approach, and will show best practices by different users.

Our current power grid infrastructure is being transformed into a cyberphysical energy system that heavily rely on communications/computer technologies for sensing, protection, control, and real-time operation. The strong coupling between cyber components and physical operations increase system vulnerabilities to potential cyber-related adverse events (e.g., cyber-attacks, `silent errors' due to manufacturing variability failures, hardware or software faults of monitoring devices due to code bugs, etc.).
Our current power grid infrastructure is being transformed into a cyberphysical energy system that heavily rely on communications/computer technologies for sensing, protection, control, and real-time operation. The strong coupling between cyber components and physical operations increase system vulnerabilities to potential cyber-related adverse events (e.g., cyber-attacks, `silent errors' due to manufacturing variability failures, hardware or software faults of monitoring devices due to code bugs, etc.). As a result, the reliable operation of the power system is highly dependent on the reliability of the associated cyber system. On the other hand, the malfunction of physical system components can also induce adverse effects on the cyber system availability and reliability. Consequently, monitoring, operation, risk analysis, reliability evaluation, and stability control of power systems should consider the interdependence between cyber and physical systems. In this proposed panel, current state-of-the-art methods of modeling, vulnerability analysis and mitigation for power system operation and control will be presented. We will bring together experts from academia, national labs, and utilities and have them presenting their perspectives and works on the topic™s emerging needs. The panel is aimed at engineers, scientists, researchers, educators, students, industrial utility experts, and other stakeholders who are engaged in PES community, research and education.

Long-range forces between two excited mercury atoms and associative ionization

description: The long-range quadrupole-quadrupole ($\sim R^{-5}$) and leading dispersion ($\sim R^{-6}$) interactions between all pairs of excited Hg($6s6p$) $^3P_0$, $^3P_1$, $^3P_2$, and $^1P_1$ atoms are determined. The quadrupole moments are calculated using the {\it ab initio} relativistic configuration-interaction method coupled with many-body perturbation theory. The van der Waals coefficients are approximated using previously calculated static polarizabilities and expressions for the dispersion energy that are validated with similar systems. The long-range interactions are critical for associative ionization in thermal and cold collisions, and are found to be quite different for different pairs of interacting states. Based on this knowledge and the short-range parts of previously calculated potential curves, improved estimates of the chemi-ionization cross sections are obtained.

In this paper, we quantified the uncertainty of quasi-static time-series based curtailment evaluations for two different grid-support functions (autonomous Volt-Var and centralized photovoltaic curtailment for preventing reverse power conditions) through extensive sensitivity analyses and hardware testing.
By strategically curtailing active power and providing reactive power support, photovoltaic (PV) systems with advanced inverters can mitigate voltage and thermal violations in distribution networks. Quasi-static time-series (QSTS) simulations are increasingly being utilized to study the implementation of these inverter functions as alternatives to traditional circuit upgrades. However, QSTS analyses can yield significantly different results based on the availability and resolution of input data and other modeling considerations. In this paper, we quantified the uncertainty of QSTS-based curtailment evaluations for two different grid-support functions (autonomous Volt-Var and centralized PV curtailment for preventing reverse power conditions) through extensive sensitivity analyses and hardware testing. We found that Volt-Var curtailment evaluations were most sensitive to poor inverter convergence (-56.4%), PV time-series data (-18.4% to +16.5%), QSTS resolution (-15.7%), and inverter modeling uncertainty (+14.7%), while the centralized control case was most sensitive to load modeling (-26.5% to +21.4%) and PV time-series data (-6.0% to +12.4%). These findings provide valuable insights for improving the reliability and accuracy of QSTS analyses for evaluating curtailment and other PV impact studies.
The WIYN Open Cluster Study Photometric Binary Survey: Initial Findings for NGC 188

description: The WIYN open cluster study (WOCS) has been working to yield precise magnitudes in the Johnson-Kron-Cousins UBVRI system for all stars in the field of a selection of ``prototypical'' open clusters. Additionally, WOCS is using radial velocities to obtain orbit solutions for all cluster binary stars with periods of less than 1000 days. Recently, WOCS is being expanded to include the near-infrared JHK_s (deep ground-based plus 2MASS) and mid-infrared ([3.6], [4.5], [5.8], [8.0]) photometry from Spitzer/IRAC observations. This multi-wavelength data (0.3--8.0 microns) allows us photometrically to identify binaries, with mass ratios from 1.0--0.3, across a wide range of primary masses. The spectral energy distribution (SED) fitter by Robitaille et al. (2007) is used to fit the fluxes of 10--12 bands, converted from the observed magnitudes, to Kurucz stellar models. Using this photometric technique, we find that NGC 188 has a binary fraction of 36--49% and provide a star-by-star comparison to the WOCS radial velocity-based binary study.

DESCRIPTION
Thallus encrusting, monomerous; non-coaxial VC, cells of the VC measure 16 to 24 µm in length and 12 to 18 µm in diameter. Cells of PF irregularly arranged with variable shapes that measure 12 to 22 µm in length and 8 to 18 µm in diameter. Epithallial cells flattened to round, measuring 5 to 7 µm long and 8 to 14 µm in diameter. Cell fusions are present both in the PF and VC (Table 1). Uniporate conceptacles raised above the thallus surface, cell linings in the pore canals more or less parallel to the roof of the conceptacle.
REMARKS
The specimens resemble the material described from the middle Miocene of Gârbova de Sus Formation, Transylvanian Basin, Romania (Chelaru & Bucur 2016). Spongites fruticulosus Kützing stratigraphically ranges from the Oligocene to Recent (Chelaru & Bucur 2016 and references therein). This species is widespread in the Mediterranean Sea as a rhodolith-forming coralline alga (Basso & Rodondi 2006) (Table 2).

Hydromagnetic Instability in plane Couette Flow

description: We study the stability of a compressible magnetic plane Couette flow and show that compressibility profoundly alters the stability properties if the magnetic field has a component perpendicular to the direction of flow. The necessary condition of a newly found instability can be satisfied in a wide variety of flows in laboratory and astrophysical conditions. The instability can operate even in a very strong magnetic field which entirely suppresses other MHD instabilities. The growth time of this instability can be rather short and reach $\sim 10$ shear timescales.
