description: We calculate the shear viscosity and anomalous baryon number violation rate in quantum field theories at finite temperature having gravity duals with hyperbolic horizons. We find the explicit dependence of these quantities on the temperature. We show that the ratio of shear viscosity to entropy density is below $1/(4π)$ at all temperatures and it can be made arbitrarily small in the low temperature limit.

Slides presented at webinar:  Battery Storage Technologies and Their Potential Applications in the Power Systems
Electrical power infrastructures are changing dramatically around the globe due to smart grid initiatives, the establishment of renewables and the resulting distributed nature of creating electricity. As a result, the power network faces great challenges in generation, transmission and distribution to meet new and many times unpredictable demands of providing coherent electricity supply.  Electrical Energy Storage (EES) has been considered a game-changer with a number of technologies that have great potential in meeting these challenges.
However, the wide variety of options and complex performance matrices can make it difficult to appraise a specific EES technology for a particular application. This presentation intends to contribute information that will give a Smart Grid user a clearer picture of the state-of-the-art electrochemical technologies available, and where they would be suited for integration into a power generation and distribution system.

description: A quantum phase transition (QPT) in a heavy-fermion (HF) compound may destroy the Fermi liquid groundstate. However, the conditions for this breakdown have remained obscure. We report the first direct investigation of heavy quasiparticle formation and breakdown in the canonical system CeCu$_{6-x}$Au$_x$ by ultraviolet photoemission spectroscopy at elevated temperatures without the complications of lattice coherence. Surprisingly, the single-ion Kondo energy scale $T_K$ exhibits an abrupt step near the quantum critical Au concentration of $x_c=0.1$. We show theoretically that this step is expected from a highly non-linear renormalization of the local spin coupling at each Ce site, induced by spin fluctuations on neighboring sites. It provides a general high-temperature indicator for HF quasiparticle breakdown at a QPT.

Evaluation of slope stability under water and seismic load through the Minimum Lithostatic Deviation method
Creators: name: Paparo, Maria Ausilia <1983>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2014
Subjects: GEO/10 Geofisica della terra solida

description: The main objective of this thesis is to obtain a better understanding of the methods to assess the stability of a slope. 
We have illustrated the principal variants of the Limit Equilibrium (LE) method found in literature, focalizing our attention on the Minimum Lithostatic Deviation (MLD) method, developed by Prof. Tinti and his collaborators (e.g. Tinti and Manucci, 2006, 2008). 
We had two main goals: the first was to test the MLD method on some real cases. We have selected the case of the Vajont landslide with the objective to reconstruct the conditions that caused the destabilization of Mount Toc, and two sites in the Norwegian margin, where failures has not occurred recently, with the aim to evaluate the present stability state and to assess under which conditions they might be mobilized.
The second goal was to study the stability charts by Taylor and  by Michalowski, and to use the MLD method to investigate the correctness and adequacy of this engineering tool.

Publisher: name: IEEE
Year: 2017

Slides presented at Integrated Distribution Planning
The electric grid as it stands today was designed for an exclusively one-way
powerflow from bulk generation facilities, encompassing plants from base load
support to peaker plants, to end-users. In this model, instantaneous demand
changes were accommodated through small, temporary frequency adjustments,
quickly reversed through appropriate management of bulk generation output.
Distributed Energy Resources (DER) present a substantial challenge to the traditional
model. Not only can powerflows reverse during peak for several hours each day, the
output of these new sources can also change much more quickly, potentially leading
to much more dramatic demand swings for bulk generation than the current system
can accommodate.
This presentation will present a framework for analyzing new requirements for the
grid during the phases of the DER roll out and discuss how systems and capabilities
have to change to ensure safe and reliable power delivery as the grid undergoes its
most fundamental technical and business change since its creation.

Slides presented at webinar:  Assessment of DERMS Deployment Under Various Operating Conditions
Under the California Electric Program Investment Charge (EPIC-1) project for Distributed Control for Smart Grid, San Diego Gas & Electric conducted a demonstration of various DERMS use cases. The demonstration consisted of the modeling of two SDG&E substations and feeders with an open tie and various downline DERs and devices. The softward was written and delivered by Advanced Control Systems. The seminar will summarize the findings, benefits and recommendations related to a DERMS installation. The demonstration consisted of control of LTCs, Voltage regulators, capacitors, switches and DERs. The DERs were 2MW PV inverters with a 2MW energy storage unit, each operating with injection into the grid. Various use cases were demonstrated to study quiescent and stress operating states including failure modes, low and high DER injection modes, low and high load conditions, with the transition performance between each mode of operation. Three classical control technologies were compared and will be reported for each demonstration.
Exciton-plasmon states in nanoscale materials: breakdown of the Tamm-Dancoff approximation

description: Within the Tamm-Dancoff approximation ab initio approaches describe excitons as packets of electron-hole pairs propagating only forward in time. However, we show that in nanoscale materials excitons and plasmons hybridize, creating exciton--plasmon states where the electron-hole pairs oscillate back and forth in time. Then, as exemplified by the trans-azobenzene molecule and carbon nanotubes, the Tamm-Dancoff approximation yields errors as large as the accuracy claimed in ab initio calculations. Instead, we propose a general and efficient approach that avoids the Tamm--Dancoff approximation, and correctly describes excitons, plasmons and exciton-plasmon states.

Slides presented at Cybersecurity for the Smart Grid: Challenges and R&D Directions
Modern electric power grid is a complex cyber-physical critical infrastructure that forms the lifeline of our society, its reliable, secure, and resilient operation is of paramount importance to national security and economic well-being. In recent years, there has been growing concerns over the cybersecurity of the power grid, due to both from increasing trend of cyber-attacks and the sophistication of these attacks. For instance, cyber attacks on Ukrainian power grid in 2015 and 2016, and also increasing number attempts to infiltrate into grid infrastructures of many nations underscore the urgency and importance of this issue. This talk first focuses on the technical challenges associated with protecting the grid, and then discusses R and D directions, and best practices to achieve cybersecurity. In particular, a holistic cybersecurity framework - encompassing attack deterrence, prevention, detection, mitigation, resilience, and attribution (forensics) - is discussed. The concepts of end-to-end-security, defense-in-depth, attack-resiliency, and cybersecurity testbeds are also briefly discussed.

description: The 1/N expansion of the two-particle irreducible effective action offers a powerful approach to study quantum field dynamics far from equilibrium. We investigate the effective convergence of the 1/N expansion in the O(N) model by comparing results obtained numerically in 1+1 dimensions at leading, next-to-leading and next-to-next-to-leading order in 1/N as well as in the weak coupling limit. A comparison in classical statistical field theory, where exact numerical results are available, is made as well. We focus on early-time dynamics and quasi-particle properties far from equilibrium and observe rapid effective convergence already for moderate values of 1/N or the coupling.

Slides presented at webinar:  Augmenting Situational Intelligence and Reducing Operator Stress During Storm Damage Assessment and Outage Restoration
For utility distribution operations center (DOC) personnel, a new type of intelligence called situational intelligence (SI) is emerging. The industry definition continues to evolve, but in general terms, SI can be defined as getting the right information to the right person at the right time, to support situationally intelligent decisions and actions. Big data and analytics software cannot give intelligence to an individual DOC operator. Too much information without the supporting expertise and process knowledge could lead to less effective decisions in the height of a storm.

This webinar - presented by Jennifer Reeves of GE's Grid Solutions - explores the eco-system of human behaviors, traits and supporting technological advances in the software user experience (UX) that will help utility companies foster a heightened level of situational intelligence in their DOC, resulting in better quality decision making and action taking at the height of a crisis.

The force standard for calibration is the universal gravitation between four masses separated by known distances. It is realized by two test masses suspended as the part of torsion pendulum and two source masses on a rotation table. Two force generation mechanisms, optical force from radiation pressure and electrostatic force by capacitive actuation unit, are designed and will be calibrated by the gravitation force. We present our recent results of radiation pressure measurements, and describe the design of capacitive displacement sensing/actuating unit.

This presentation will review the concept of interoperability and the IEEE Std 2030-2011, Guide for Smart Grid Interoperability of Energy Technology and Information Technology Operation with the Electric Power System (EPS), and End-Use Applications and Loads. It provides an overview the smart grid interoperability reference model (SGIRM).
A smart grid standardization roadmap was developed in 2010 by the IEC that is similar to the framework and roadmap developed by NIST. Standards developing organizations (e.g., IEEE) -using an open and balanced consensus process- are establishing standards for the smart grid, building off of the conceptual reference models produced by NIST.
IEEE Std 2030-2011 supports EISA, the NIST framework coordination efforts, IEC interests, and additional smart grid applications. It focuses on a systems-level approach to understanding and guidance for interoperability components of communications, power systems, and information technology platforms.
This landmark standard needs to be reinforced for Working Groups and users of standards.

Year: 2018

Slides presented at webinar:  Load Modeling and Resilience for Electric Distribution Systems
The Webinar will describe two US DOE Grid projects at Argonne National Laboratory. The first project is on load modeling in distribution grid. There emerges the need of revisiting and improving load modeling techniques especially for distribution grid due to the fact that Most of existing load models assume loads are passive, deterministic and time-invariant, with few appropriate models to correctly represent a variety of DGs and new types of loads. With the modern instrumentation for measurements, the modernized load modeling becomes possible and substantial. The project focuses on developing both static and transient models for multiple levels of system, and designing associated model identification approaches.
The other project is on distribution system resilience and restoration. Recent severe power outages caused by extreme weather events have highlighted the importance and urgency of improving the resilience and restoration of the electric power grid. The objective of the project is to design a distribution restoration decision support tool to assist distribution utility operators in making optimal and effective decisions during system restoration.

description: In order to understand why the inter- and intra-granular current densities of polycrystalline superconducting oxypnictides differ by three orders of magnitude, we have conducted combined magneto-optical and microstructural examinations of representative randomly oriented polycrystalline Nd and Sm single-layer oxypnictides. Magneto optical images show that the highest Jc values are observed within single grains oriented with their c axes perpendicular to the observation plane, implying that the intragranular current is anisotropic. The much lower intergranular Jc is at least partially due to many extrinsic factors, because cracks and a ubiquitous wetting As-Fe phase are found at many grain boundaries. However, some grain boundaries are structurally clean under high resolution transmission electron microscopy examination. Because the whole-sample global Jc(5K) values of the two samples examined are 1000-4000 A/cm2, some 10-40 times that found in random, polycrystalline YBa2Cu3O7-x, it appears that the dominant obstruction to intergranular current flow of many present samples is extrinsic, though some intrinsic limitation of current flow across grain boundaries cannot yet be ruled out.

Slides presented at webinar:  Application of Microgrids and Distributed Generation
The purpose of this webinar is to familiarize participants with a vision for the future of microgrids and distributed generation. The webinar begins with a discussion of key industry/societal trends. The smarter grid highlights the intelligence that has already been implemented, and the new intelligence being added to the grid today. The Smart Grid technology roadmap provides examples of six Smart Grid solutions being deployed today. The importance of integration of technology components is emphasized, and its impact on grid resiliency. The 16 Smart Grid foundational industry standards are critical for effective integration of technology components and successful interoperability. Interoperability requires communications between technology components (i.e., utilizing communications protocols) and effective exchange of information between technology components. Emerging technologies in microgrids and distributed generation include voltage regulation equipment, grid edge controllers and smart inverters. One impact of high penetration of rooftop solar PV on the distribution system is three new applications of power electronics. Lessons learned in microgrids and distributed generation are discussed, which include impediments to be addressed and enablers for success. The IEEE Power & Energy Society (PES) input to the DOE for the Quadrennial Energy Review (QER) on the vision for microgrids and distribution generation is summarized, including technology, standards, policy and the business case.

Australia has currently the largest residential photovoltaic (PV) penetration in the world, with almost 1 in 5 houses with the technology. Battery storage systems are also becoming attractive as they allow storing excess PV generation during the day to use it later at night. However, PV-rich communities will pose significant technical and economic challenges on distribution networks - but also some opportunities. For this PV-rich future to thrive, more intelligent, flexible electricity networks, also known as Smart Grids, are likely to play an important role. But for Smart Grids to emerge, the traditional Distribution Network Service Provider (DNSP) needs to evolve into an engaged, flexible Distribution System Operator (DSO) in which network elements and participants (consumers, generators, and those that do both) are actively managed to fulfill technical, economic, and environmental objectives.

title: Four films: crossing the boundaries of modernism and postmodernism
Creators: name: Eyuboglu, Selim
Publisher: name: University of Kent
Year: 2021

description: This work is based on studying films from the perspective of modernism, late-modernism, postmodernism and film theory. The introduction on the major issues and debates on late-modernism and postmodernism will be followed by the textual analysis of four films: Luchino Visconti's Death in Venice, Michaelangelo Antonioni's L'avventure, Alfred Hitchcock's Blackmail and David Lynch's Blue Velvet. I argue that Death in Venice is a wholly intended modernist film that inscribes itself into the tradition of modernism by rewriting other modernist texts, notably the literary work of Thomas Mann and the modernist theories of Theodor Adorno. In this respect, the film is a late-modern, as it embodies the discourses of modernism. L'avventura both presents a modernist narration and departure from European cinematic tradition. Its shifting between post-neorealism, an ironic authorship and an organization of desire that propels the narrative suggest a postmodern departure from late-modern cinema. Blackmail parodies modernism from within. By quoting the styles of modernist movements the film establishes an ironic distance from modernism itself; at the same time, it ironically assimilates an institutionalized narrative that suggests the impossibility of a fully modernist narration. Finally, I argue that as a postmodern film Blue Velvet surrounds its story material with meta-textual references that subverts the unity between the story and its narration. However, the author's intention to 'master' his narrating by a network of extra-diegetic references inscribes a modernist strategy into a postmodern film.

description: The recently launched satellite, Fermi Gamma-ray Space Telescope, is expected to find out if cosmic-ray (CR) protons are generated from supernova remnants (SNRs), especially RX J1713.7-3946, by observing the GeV-to-TeV gamma-rays. The GeV emission is thought to be bright if the TeV emission is hadronic, i.e., of proton origin, while dim if leptonic. We reexamine the above view using a simple theoretical model of nonlinear acceleration of particles to calculate the gamma-ray spectrum of Galactic young SNRs. If the nonlinear effects of CR acceleration are considered, it may be impossible to distinguish the evidence of proton acceleration from leptonic in the gamma-ray spectrum of Galactic young SNRs like RX J1713.7-3946. On the other hand, future km^3-class neutrino observations will likely find a clear evidence of the proton acceleration there.

description: The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field. For this reason, the ability of a particle to approach a spacecraft in LEO depends on its energy and the position of the spacecraft within the Earth' magnetosphere. Moreover, there are some areas (radiation belts) where the particles are trapped for a long time, and therefore the flux of energetic particles is particularly high. Occasionally, SEP contribute to the energetic particle flux too. DOSTEL is one of the instruments aboard the \ac{ISS} that monitors the radiation field within the European module Columbus. Because being installed inside the \ac{ISS}, particles produced by the interaction between the "primary" radiation and the ISS materials are also measured. To describe the observations in such a complex radiation field, we follow the method by Caballero-Lopez and Moraal (2012) in order to compute the so-called yield function using precise measurements of the proton and Helium energy spectra obtained by AMS and the systematic variation of the DOSTEL measurements within the Earth's magnetosphere

Slides presented at webinar:  Financial Transmission and Storage Rights
The intermittency of wind and solar power make it difficult to balance the supply of and demand for electric power. Energy storage and flexible load aggregations can solve this problem by storing power in times of surplus and releasing power during deficits. Presently, high costs and technical complexity hinder the use of storage and load flexibility in power systems.

In this webinar, we present the financial storage right, a new market mechanism that enables storage to participate in electricity markets in the same manner as transmission lines, and further enables risk-averse market participants to hedge against price volatility due to congestion.

description: In this paper, as a first step toward frame-like gauge invariant formulation for massive mixed symmetry bosonic fields, we consider mixed tensors, corresponding to Young tableau with two rows with k >= 2 boxes in the first row and only one box in the second one. We construct complete Lagrangian and gauge transformations describing massive particles in (anti) de Sitter space-time with arbitrary dimension d >= 4 and investigate all possible massless and partially massless limits.

On the stability of planetary orbits in binary star systems I. The S-type orbits

description: Many exoplanets are discovered in binary star systems in internal or in circumbinary orbits. Whether the planet can be habitable or not depends on the possibility to maintain liquid water on its surface, and therefore on the luminosity of its host stars and on the dynamical properties of the planetary orbit. The trajectory of a planet in a double star system can be determined, approximating stars and planets with point masses, by solving numerically the equations of motion of the classical three-body system. In this study, we analyze a large data set of planetary orbits, made up with high precision long integration at varying: the mass of the planet, its distance from the primary star, the mass ratio for the two stars in the binary system, and the eccentricity of the star motion. To simulate the gravitational dynamics, we use a 15th order integration scheme (IAS15, available within the REBOUND framework), that provides an optimal solution for long-term integration. In our data analysis, we evaluate if an orbit is stable or not and also provide the statistics of different types of instability: collisions with the primary or secondary star and planets ejected away from the binary star system. Concerning the stability, we find a significant number of orbits that are only marginally stable, according to the classification introduced by Musielak et al. 2005. For planets of negligible mass, we estimate the critical semi-major axis $a_c$ as a function of the mass ratio and the eccentricity of the binary, in agreement with the results of Holman and Wiegert 1999. However, we find that for very massive planets (Super-Jupiters) the critical semi-major axis decrease in some cases by a few percent, compared to cases in which the mass of the planet is negligible.

description: The F doped LaFeAsO, a recently discovered superconductor with the high Tc of 26 K, has been studied by the resistivity, magnetic susceptibility, and heat capacity measurements in the F doping range from 0 to 0.14 (x in LaFeAsO1-xFx). In the low temperature region, a T3lnT term in the heat capacity and a T2 term in the magnetic susceptibility, which are derived from the spin fluctuation, are observed. The nearly ferromagnetic nature evidenced by a large Wilson ratio (6.5 for x = 0, and 11.2 for x = 0.025) suggests that the superconductivity in the LaFeAsO system is mediated by ferromagnetic spin fluctuation.

Blockchain for E&U - is it hype or reality?  Blockchain is a new pattern in IT that dramatically changes the support of transactions between market participants that form an eco-system or business network. This particularly of importance for the energy & utility industry that is undergoing major transformation. This transformation leads to more frequent transactions and additional challenges linked to growth of distributed energy resources and number of market participants.
Fluxonic Cellular Automata

description: We formulate a new concept for computing with quantum cellular automata composed of arrays of nanostructured superconducting devices. The logic states are defined by the position of two trapped flux quanta (vortices) in a 2x2 blind-hole-matrix etched on a mesoscopic superconducting square. Such small computational unit-cells are well within reach of current fabrication technology. In an array of unit-cells, the vortex configuration of one cell influences the penetrating flux lines in the neighboring cell through the screening currents. Alternatively, in conjoined cells, the information transfer can be strengthened by the interactions between the supercurrents in adjacent cells. Here we present the functioning logic gates based on this fluxonic cellular automata (FCA), where the logic operations are verified through theoretical simulations performed in the framework of the time-dependent Ginzburg-Landau theory. The input signals are defined by current loops placed on top of the two diagonal blind holes of the input cell. For given current-polarization, external flux lines are attracted or repelled by the loops, forming the '0' or '1' configuration. The read-out technology may be chosen from a large variety of modern vortex imaging methods, transport and LDOS measurements.

Slides presented at webinar:  DER: Where to Start? With who, what, when, why? How to build a ROI based Roadmap
New grid edge technologies are proliferating, and utilities must figure out how to leverage them, or get sidelined in areas of growth. Utility customers are installing rooftop solar, smart appliances, EVs, etc, outside the traditional purview of the utility or regulators.

The mix of IT technologies and business models to optimally interact with these new customer sited resources is critical. What is needed is an expert system integrator who can assess the Utility as is condition, and roadmap deployment of internal and external technologies that optimally bring the utility to the to be scenario that allows them to most profitably leverage DER.

IBM is such a system integrator, and this webinar will explain how to tactically create and deliver such a roadmap.

description: We establish that QED3 can possess a critical number of flavours, N_f^c, associated with dynamical chiral symmetry breaking if, and only if, the fermion wave function renormalisation and photon vacuum polarisation are homogeneous functions at infrared momenta when the fermion mass function vanishes. The Ward identity entails that the fermion-photon vertex possesses the same property and ensures a simple relationship between the homogeneity degrees of each of these functions. Simple models for the photon vacuum polarisation and fermion-photon vertex are used to illustrate these observations. The existence and value of N_f^c are contingent upon the precise form of the vertex but any discussion of gauge dependence is moot. We introduce an order parameter for confinement. Chiral symmetry restoration and deconfinement are coincident owing to an abrupt change in the analytic properties of the fermion propagator when a nonzero scalar self-energy becomes insupportable.

description: As we enter the era of large-scale imaging surveys with the up-coming telescopes such as LSST and SKA, it is envisaged that the number of known strong gravitational lensing systems will increase dramatically. However, these events are still very rare and require the efficient processing of millions of images. In order to tackle this image processing problem, we present Machine Learning techniques and apply them to the Gravitational Lens Finding Challenge. The Convolutional Neural Networks (CNNs) presented have been re-implemented within a new modular, and extendable framework, LEXACTUM. We report an Area Under the Curve (AUC) of 0.9343 and 0.9870, and an execution time of 0.0061s and 0.0594s per image, for the Space and Ground datasets respectively, showing that the results obtained by CNNs are very competitive with conventional methods (such as visual inspection and arc finders) for detecting gravitational lenses.
