description: Objective evaluation (OE) is essential to artificial music, but it's often very hard to determine the quality of OEs. Hitherto, subjective evaluation (SE) remains reliable and prevailing but suffers inevitable disadvantages that OEs may overcome. Therefore, a meta-evaluation system is necessary for designers to test the effectiveness of OEs. In this paper, we present Armor, a complex and cross-domain benchmark dataset that serves for this purpose. Since OEs should correlate with human judgment, we provide music as test cases for OEs and human judgment scores as touchstones. We also provide two meta-evaluation scenarios and their corresponding testing methods to assess the effectiveness of OEs. To the best of our knowledge, Armor is the first comprehensive and rigorous framework that future works could follow, take example by, and improve upon for the task of evaluating computer-generated music and the field of computational music as a whole. By analyzing different OE methods on our dataset, we observe that there is still a huge gap between SE and OE, meaning that hard-coded algorithms are far from catching human's judgment to the music.

description: Elucidating photochemical reactions is vital to understand various biochemical phenomena and develop functional materials such as artificial photosynthesis and organic solar cells, albeit its notorious difficulty by both experiments and theories. The best theoretical way so far to analyze photochemical reactions at the level of ab initio electronic structure is the state-averaged multi-configurational self-consistent field (SA-MCSCF) method. However, the exponential computational cost of classical computers with the increasing number of molecular orbitals hinders applications of SA-MCSCF for large systems we are interested in. Utilizing quantum computers was recently proposed as a promising approach to overcome such computational cost, dubbed as state-averaged orbital-optimized variational quantum eigensolver (SA-OO-VQE). Here we extend a theory of SA-OO-VQE so that analytical gradients of energy can be evaluated by standard techniques that are feasible with near-term quantum computers. The analytical gradients, known only for the state-specific OO-VQE in previous studies, allow us to determine various characteristics of photochemical reactions such as the conical intersection (CI) points. We perform a proof-of-principle calculation of our methods by applying it to the photochemical cis-trans isomerization of 1,3,3,3-tetrafluoropropene. Numerical simulations of quantum circuits and measurements can correctly capture the photochemical reaction pathway of this model system, including the CI points. Our results illustrate the possibility of leveraging quantum computers for studying photochemical reactions.

Proxy Application Driven Codesign for Power Systems Analytics on Extreme-Scale Architectures
Creators: S. Peles
Publisher: name: IEEE
Year: 2022

Modern scientific applications are complicated and require coordination of several components. Proxy application driven software-hardware codesign plays a vital role in driving innovation among the developments of applications, software infrastructure and hardware architecture. Proxy applications are self-contained and simplified codes that are intended to model the performance-critical computations within applications. Power systems are susceptible to congestion, renewable curtailment, and loss of load. Numerical simulations and machine learning models to study the impact of potentially adverse events on the power grid under variable and uncertain generation are actively researched. Modeling dynamical systems such as the power grid on HPC systems often exhibit irregular computation and memory accesses, reasons behind performance bottlenecks at scale. Such use cases are rarely explored for performance characterization. In this panel, we discuss the prospect of proxy applications in analyzing the performance of power systems analytics on extreme-scale hardware architectures: spanning GPUs to massively parallel system-on-chip architectures.

description: This study aimed to provide a framework to evaluate team attacking performances in rugby league using 59,233 plays from 180 Super League matches via expected possession value (EPV) models. The EPV-308 split the pitch into 308 5m x 5m zones, the EPV-77 split the pitch into 77 10m x 10m zones and the EPV-19 split the pitch in 19 zones of variable size dependent on the total zone value generated during a match. Attacking possessions were considered as Markov Chains, allowing the value of each zone visited to be estimated based on the outcome of the possession. The Kullback-Leibler Divergence was used to evaluate the reproducibility of the value generated from each zone (the reward distribution) by teams between matches. The EPV-308 had the greatest variability and lowest reproducibility, compared to EPV-77 and EPV-19. When six previous matches were considered, the team's subsequent match attacking performances had a similar reward distribution for EPV-19, EPV-77 and EPV-308 on 95 +/- 4%, 51 +/- 12% and 0 +/- 0% of occasions. This study supports the use of EPV-19 to evaluate team attacking performance in rugby league and provides a simple framework through which attacking performances can be compared between teams.

Nation's power grid is constantly facing extreme weather-related outages including the most recent Texas (2021) blackout.   Power grids in coastal regions are more vulnerable to hurricane-related events. For example, hurricanes Harvey, Irma, and Maria left more than 7.5 million residents in various coastal communities in Texas, Florida, and Puerto Rico without electricity. Utilities in those areas are constantly adopting new technologies and strategies at different stage of planning and operations to lower the impact of extreme weather on power outage. Similarly, the R&D community is developing tools and methods useful for power distribution utilities for enhancing the service reliability during the extreme weather events. In this context, this panel proposes to bring together experts from utilities and R&D community to disseminate experience learned by the utilities in managing distribution grids during the past extreme weather events, and to share the state-of-the-art methods and tools valuable for the utilities in managing the power distribution networks during those extreme events.

description: An easy-to-implement form of the Metropolis Algorithm is described which, unlike most standard techniques, is well suited to sampling from multi-modal distributions on spaces with moderate numbers of dimensions (order ten) in environments typical of investigations into current constraints on Beyond-the-Standard-Model physics. The sampling technique makes use of pre-existing information (which can safely be of low or uncertain quality) relating to the distribution from which it is desired to sample. This information should come in the form of a ``bank'' or ``cache'' of space points of which at least some may be expected to be near regions of interest in the desired distribution. In practical circumstances such ``banks of clues'' are easy to assemble from earlier work, aborted runs, discarded burn-in samples from failed sampling attempts, or from prior scouting investigations. The technique equilibrates between disconnected parts of the distribution without user input. The algorithm is not lead astray by ``bad'' clues, but there is no free lunch: performance gains will only be seen where clues are helpful.

description: We report neutron scattering studies of the spin correlations of the geometrically frustrated pyrochlore Tb2Mo2O7 using single crystal samples. This material undergoes a spin-freezing transition below Tg~24 K, similar to Y2Mo2O7, and has little apparent chemical disorder. Diffuse elastic peaks are observed at low temperatures, indicating short-range ordering of the Tb moments in an arrangement where the Tb moments are slightly rotated from the preferred directions of the spin ice structure. In addition, a Q-independent signal is observed which likely originates from frozen, but completely uncorrelated, Tb moments. Inelastic measurements show the absence of sharp peaks due to crystal field excitations. These data show how the physics of the Tb sublattice responds to the glassy behavior of the Mo sublattice with the associated effects of lattice disorder.

description: The naive time reversal odd (``T-odd'') parton distribution $h_{1}^{\perp}$, the so-called Boer-Mulders function, for both up ($u$) and down ($d$) quarks is considered in the diquark spectator model. While the results of different articles in the literature suggest that the signs of the Boer-Mulders function in semi-inclusive DIS for both flavors $u$ and $d$ are the same and negative, a previous calculation in the diquark-spectator model found that $h_{1}^{\perp(u)}$ and $h_{1}^{\perp(d)}$ have different signs. The flavor dependence is of significance for the analysis of the azimuthal $\cos(2ϕ)$ asymmetries in unpolarized SIDIS and DY-processes, as well as for the overall physical understanding of the distribution of transversely polarized quarks in unpolarized nucleons. We find substantial differences with previous work. In particular we obtain half and first moments of Boer-Mulders function that are negative over the full range in Bjorken $x$ for both the $u$- and $d$- quarks. In conjunction with the Collins function we then predict the $\cos(2ϕ)$ azimuthal asymmetry for $π^{+}$ and $π^{-}$ in this framework. We also find that the Sivers $u$- and $d$- quark are negative and positive respectively. As a by-product of the formalism, we calculate the chiral-odd but ``T-even'' function $h_{1L}^{\perp}$, which allows us to present a prediction for the single spin asymmetry $A_{UL}^{\sin(2ϕ)}$ for a longitudinally polarized target in SIDIS.

description: We analyze the subgap excitations and phase diagram of a quantum dot (QD) coupled to a semiconducting nanowire fully wrapped by a superconducting (S) shell. We take into account how a Little-Parks (LP) pairing fluxoid (a winding in the S phase around the shell) influences the proximity effect on the dot. We find that under axially symmetric QD-S coupling, shell fluxoids cause the induced pairing to vanish, producing instead a level renormalization that pushes subgap levels closer to zero energy and flattens fermionic parity crossings as the coupling strength increases. This fluxoid-induced stabilization mechanism has analoges in symmetric S-QD-S Josephson junctions at phase $π$, and can naturally lead to patterns of near-zero modes weakly dispersing with parameters in all but the zero-th lobe of the LP spectrum.

description: Previous LHC forecasts for the constrained minimal supersymmetric standard model (CMSSM), based on current astrophysical and laboratory measurements, have used priors that are flat in the parameter tan beta, while being constrained to postdict the central experimental value of MZ. We construct a different, new and more natural prior with a measure in mu and B (the more fundamental MSSM parameters from which tan beta and MZ are actually derived). We find that as a consequence this choice leads to a well defined fine-tuning measure in the parameter space. We investigate the effect of such on global CMSSM fits to indirect constraints, providing posterior probability distributions for Large Hadron Collider (LHC) sparticle production cross sections. The change in priors has a significant effect, strongly suppressing the pseudoscalar Higgs boson dark matter annihilation region, and diminishing the probable values of sparticle masses. We also show how to interpret fit information from a Markov Chain Monte Carlo in a frequentist fashion; namely by using the profile likelihood. Bayesian and frequentist interpretations of CMSSM fits are compared and contrasted.

In this paper we investigate classical rotating membranes representing analog of a specific class of string spiky solutions. Using the reduction to the Neumann-Rosochatius integrable system we find analog of the string single spike solutions. In contrast to the magnon-like solutions, this case is characterized with finite difference of energy and ``winding number'' and finite spins as well.

Energy transitions worldwide are pushing towards more sustainable societies demanding for more environmentally friendly power generation and urging to reduce technology based on nuclear and fossil sources to a minimum. Moreover, future energy systems are evolving to low-inertia networks where utilities are staring to face new challenges associated to the dramatic increase of inverter-connected devices. Consequently, utilities require higher degree of observability in the network and thus are becoming more dependent of advanced metering infrastructure, monitoring systems and high frequency synchronized wide-area devices in order to improve the decision making and situational awareness of the transmission system. As solution, utilities have adopted methods to handle, process and analyze the information acquired. Since the characteristics of the power systems are considerably different due to the diverse geographical locations, dimension of the systems and nature of the loads, the current handling processes are not necessarily the same nor the most advanced solutions. In this context, the IEEE Task Force Application of Big Data Analytic on Transmission System for Dynamic Security Assessment has recently completed a survey to 10 different utilities around the world and the aim of this panel is to present the most important findings and to provide a space of discussion about how the current practices in control rooms could be improved.

description: "Europe in Polish Public Discourse" by Grzegorz Żuk depicts linguistic patterns of "Europe" in Polish debates on history, society, as well as in contemporary Polish media. One may promptly identify that the book addresses the most interesting questions at the frontiers of Polish studies. These range from such areas as the evolution of Polish society and politics, economic transformation after 1989, Polish identity in the EU context, to ideas of modernization, Europeanization or globalization in contemporary Polish thought. The book is structured in four parts. Part 1 uncovers the notion of 'Europe' and its connotations in Polish discourse. Parts 2 and 3 compare historical Polish understandings of Europe and modern Polish interpretations of European integration in the context of Polish self-perception. Part 4 highlights the findings on how to reconstruct the picture of Europe in the consciousness of the Polish society. The book's source basis is framed by period of 1989-2004 years.

description: Robert Spät's book, published in "Studien zur Ostmitteleuropaforschung", a series of works devoted to Eastern European studies, deals with the public discourse in the German Empire on the "Polish question" from the end of Caprivi's era (1894) until the fall of the Kaiserreich (1918). Starting with a broad introduction of the situation of the Polish minority in Eastern Prussia, and the Posen region in particular, the author chronologically presents the key developments in the first part of his book: the Września school strike [Wreschener Schulstreik] in 1901, the expropriation law and the language laws (both 1908). In the second part, he focuses on the conquest of the Congress Poland by the Kaiserreich during the First World War, the establishment of the Kingdom of Poland by the Central Powers in 1916, the Brest Treaty (1918) as well as on the impact that those issues had on internal discourse in Prussia. In his conclusions, the author briefly sketches how these developments influenced the German-Polish relations in the following years until the present.

As buildings become smarter, and as sensor systems, internet connectivity and data collection become more ubiquitous, there are substantial opportunities to improve the performance and efficiency of buildings. Moreover, the groups of buildings combined with distributed energy resources (DERs), such as electric vehicle (EV) and photovoltaic (PV) generation, can reliably and cost?effectively serve as grid assets by strategically deploying efficiency and demand flexibility. Thus, there is a growing need for connected communities solutions that best integrate and optimize all our energy resources on the grid to provide Americans with the most reliable and affordable electricity possible. In this panel session, pioneering thought leaders from government, national laboratory and industry will share their latest efforts and experiences on connected communities, and discuss the associated challenges and opportunities. We expect to learn more about how connected communities can improve grid resilience while offering environmental and community benefits.

description: We show how one can systematically construct vacuum solutions to Einstein field equations with $D-2$ commuting Killing vectors in $D>4$ dimensions. The construction uses Einstein-scalar field seed solutions in 4 dimensions and is performed both for the case when all the Killing directions are spacelike, as well as when one of the Killing vectors is timelike. The later case corresponds to generalizations of stationary axially symmetric solutions to higher dimensions. Some examples representing generalizations of known higher dimensional stationary solutions are discussed in terms of their rod structure and horizon locations and deformations.

description: The relation between nuclear ($\lesssim$ 50 pc) star formation and nuclear galactic activity is still elusive: theoretical models predict a link between the two, but it is unclear whether active galactic nuclei (AGNs) should appear at the same time, before or after nuclear star formation activity is ongoing. We present a study of this relation in a complete, volume-limited sample of nine of the most luminous ($\log L_{\rm 14-195 keV} > 10^{42.5}$ erg/s) local AGNs (the LLAMA sample), including a sample of 18 inactive control galaxies (6 star-forming; 12 passive) that are matched by Hubble type, stellar mass (9.5 $\lesssim$ log M_star/M_sun $\lesssim$ 10.5), inclination and distance. This allows us to calibrate our methods on the control sample and perform a differential analysis between the AGN and control samples. We perform stellar population synthesis on VLT/X-SHOOTER spectra in an aperture corresponding to a physical radius of $\approx$ 150 pc. We find young ($\lesssim$ 30 Myr) stellar populations in seven out of nine AGNs and in four out of six star-forming control galaxies. In the non-star-forming control population, in contrast, only two out of twelve galaxies show such a population. We further show that these young populations are not indicative of ongoing star-formation, providing evidence for models that see AGN activity as a consequence of nuclear star formation. Based on the similar nuclear star-formation histories of AGNs and star-forming control galaxies, we speculate that the latter may turn into the former for some fraction of their time. Under this assumption, and making use of the volume-completeness of our sample, we infer that the AGN phase lasts for about 5 % of the nuclear starburst phase.

Crosslinked networks of stiff filaments exhibit negative normal stress

description: Motivated by recent experiments showing that stiff biopolymer gels exhibit highly unusual negative normal elastic stresses, we develop a computational model for stiff polymer networks subject to large strains. In all cases, we find that such networks develop normal stresses that are both negative and of magnitude comparable to the corresponding shear stress. We find that these normal stresses coincide with other nonlinearities in our networks, and specifically with compressive bucking of the individual filaments. Our results suggest that negative normal stresses are a characteristic feature of stiff (bio)polymer gels that have been shown to exhibit strong nonlinear elastic properties.

Atmospheric and oceanic 40- to 50-day oscillations in the source region of the Somali Current
Creators: name: Mertz, Gordon James
Publisher: name: University of British Columbia
Year: 2010

description: Current and temperature data were acquired in the source region of the Somali Current, jointly by the Universities of Kiel and Miami, as part of the INDEX pilot studies. The data were acquired over a six-month period (January-July, 1976) which spans the springtime Monsoon reversal. The experiment and the data are described in Düing and Schott (1978). This thesis describes the results of the spectrum analysis of fluctuations found in data from the experiment's two southernmost sensor locations. It is found that, once the annual cycle is removed, most of the variance in these current and temperature records resides in subinertial fluctuations. The most prominent spectral feature is a 40- to 50-day peak. This 40- to 50-day period is coincident with that of the global-scale circulation cells found in the tropical atmosphere by Madden and Julian (1971 and 1972). The analysis of wind stress and wind stress curl data for the years 1976 and 1979 presented in this thesis indicate that the 40-to 50-day oscillation was present over the Western Indian Ocean during these years. It is suggested here that wind-forcing excites a long coastally trapped wave. To test this idea, a wind-forced quasi-geostrophic, three-layer model and a reduced-gravity model incorporating lateral mean current shear are applied to the Somali Current regime. Model results suggest that the wind forcing is strong enough to excite the observed current and temperature fluctuations.

description: Das Buch vereinigt Überlegungen des Autors zu den Verbindungen der polnischen Aufklärung mit der geistigen Kulturlandschaft der ersten Rzeczpospolita, des polnisch-litauischen Unionsstaates der Frühen Neuzeit. Ein weiteres Anliegen des Autors ist es, die europäischen Einflüsse auf die polnischen Aufklärer des späten 18. und frühen 19. Jahrhunderts nachzuzeichnen. Dabei periodisiert Cieński die polnische Aufklärung in zwei, zwar ineinander übergehende aber dennoch signifikant unterschiedliche Zeiträume – einerseits die Anfänge der Regierungszeit des letzten polnischen Königs Stanisław August Poniatowski, die von einem impulsiven Modernisierungscharakter in allen Lebensbereichen geprägt waren; andererseits das Ende der Rzeczpospolita und die zahlreichen politischen Umbrüche in den 1790er Jahren und – vor dem Hintergrund der napoleonischen Kriege – zu Beginn des 19. Jahrhunderts. Der Band fasst insgesamt achtzehn, über einen Zeitraum von gut zehn Jahren entstandene Beiträge des Autors zusammen, die teils eigenständig in verschiedenen Sammelwerken erschienen sind, teils aber nur in reiner Vortragsform zu diversen Tagungen vorlagen.

description: We analyze the phases of the Sakai-Sugimoto model at finite temperature and baryon chemical potential. Baryonic matter is represented either by 4-branes in the 8-branes or by strings stretched from the 8-branes to the horizon. We find the explicit configurations and use them to determine the phase diagram and equation of state of the model. The 4-brane configuration (nuclear matter) is always preferred to the string configuration (quark matter), and the latter is also unstable to density fluctuations. In the deconfined phase the phase diagram has three regions corresponding to the vacuum, quark-gluon plasma, and nuclear matter, with a first-order and a second-order phase transition separating the phases. We find that for a large baryon number density, and at low temperatures, the dominant phase has broken chiral symmetry. This is in qualitative agreement with studies of QCD at high density.
