description: We give sufficient conditions for homotopical localization functors to preserve algebras over coloured operads in monoidal model categories. Our approach encompasses a number of previous results about preservation of structures under localizations, such as loop spaces or infinite loop spaces, and provides new results of the same kind. For instance, under suitable assumptions, homotopical localizations preserve ring spectra (in the strict sense, not only up to homotopy), modules over ring spectra, and algebras over commutative ring spectra, as well as ring maps, module maps, and algebra maps. It is principally the treatment of module spectra and their maps that led us to the use of coloured operads (also called enriched multicategories) in this context.

description: In critical phenomena, singular behaviors arise not only for thermodynamic quantities but also for transport coefficients. We study this dynamic critical phenomenon in the AdS/CFT duality. We consider black holes with a single R-charge in various dimensions and compute the R-charge diffusion in the linear perturbations. In this case, the black holes belong to model B according to the classification of Hohenberg and Halperin.

description: CaCo2As2 is a unique itinerant system having strong magnetic frustration. Here we report the effect of electron doping on the physical properties resulting from Ni substitutions for Co. The A-type antiferromagnetic transition temperature TN = 52 K for x = 0 decreases to 22 K with only 3 percent Ni substitution and is completely suppressed for x > 0.11. For 0.11 < x < 0.52 strong ferromagnetic (FM) fluctuations develop as revealed by magnetic susceptibility chi(T) measurements. Heat-capacity Cp(T) measurements reveal the presence of FM quantum spin fluctuations for 0.11 < x < 0.52. Our density-functional theory (DFT) calculations confirm that FM fluctuations are enhanced by Ni substitutions for Co. The Sommerfeld electronic heat-capacity coefficient is enhanced for x = 0, 0.21, and 0.42 by about a factor of two compared to DFT calculations of the bare density of states at the Fermi energy. The crystals with x > 0.52 do not exhibit FM spin fluctuations or magnetic order, which was found from the DFT calculations to arise from a Stoner transition. Neutron-diffraction studies of crystals with x = 0.11 and 0.16 found no evidence of A-type ordering as observed in CaCo2As2 or of other common magnetic structures.

description: The so-called regularized Biot-Savart laws (RBSLs) provide an efficient and flexible method for modeling pre-eruptive magnetic configurations of coronal mass ejections (CMEs) whose characteristics are constrained by observational images and magnetic-field data. This method allows one to calculate the field of magnetic flux ropes (MFRs) with small circular cross-sections and an arbitrary axis shape. The field of the whole configuration is constructed as a superposition of (1) such a flux-rope field and (2) an ambient potential field derived, for example, from an observed magnetogram. The RBSL kernels are determined from the requirement that the MFR field for a straight cylinder must be exactly force-free. For a curved MFR, however, the magnetic forces are generally unbalanced over the whole path of the MFR. To minimize these forces, we apply a modified Gauss-Newton method to find optimal MFR parameters. This is done by iteratively adjusting the MFR axis path and axial current. We then try to relax the resulting optimized configuration in a subsequent line-tied zero-beta magnetohydrodynamic simulation toward a force-free equilibrium. By considering two models of the sigmoidal pre-eruption configuration for the 2009 February 13 CME, we demonstrate how this approach works and what it is capable of. We show, in particular, that the building blocks of the core magnetic structure described by these models match to morphological features typically observed in such type of configurations. Our method will be useful for both the modeling of particular eruptive events and theoretical studies of idealized pre-eruptive MFR configurations.

description: In this work, we show how to discover a semantic web service among a repository of web services. A new approach for web service discovery based on calculating the functions similarity. We define the Web service functions with Ontology Web Language (OWL). We wrote some rules for comparing two web services` parameters. Our algorithm compares the parameters of two web services` inputs/outputs by making a bipartite graph. We compute the similarity rate by using the Ford-Fulkerson algorithm. The higher the similarity, the less are the differences between their functions. At last, our algorithm chooses the service which has the highest similarity. As a consequence, our method is useful when we need to find a web service suitable to replace an existing one that has failed. Especially in autonomic systems, this situation is very common and important since we need to ensure the availability of the application which is based on the failed web service. We use Universal Description, Discovery and Integration (UDDI) compliant web service registry.

IEEE PES has formed the Industry Technical Support Leadership Committee (ITSLC) to facilitate global collaboration between the IEEE and governments, regulatory, and other industry organizations, such as the U.S. DOE, and to provide fast response as required by changes that our industry is experiencing.
In 2016, IEEE signed a Memorandum of Understanding (MOU) with the U.S. Department of Energy (DOE) to address grid modernization challenges. The IEEE objective is to provide independent and unbiased viewpoints on important technical issues by leveraging IEEE membership, including Technical Committees and chapters. IEEE PES has formed the Industry Technical Support Leadership Committee (ITSLC) to facilitate global collaboration between the IEEE and governments, regulatory, and other industry organizations, such as the U.S. DOE, and to provide fast response as required by changes that our industry is experiencing. The ITSLC Force works closely with the IEEE Standards Association (SA), IEEE-USA, and other societies.

As part of the collaboration initiative, the U.S. DOE has asked IEEE to develop a whitepaper on the impact of IEEE 1547 standard on smart inverters and the applications in Power Systems. IEEE has formed a fast-track Working Group of industry experts to respond to this request in a timely fashion. This whitepaper is a revision of the whitepaper that was published in 2018 as a result of the work with a purpose not only to support the U.S. DOE initiatives in this important area, but also to provide important information and education to IEEE membership.
Radio Detection of Radio-Quiet Galaxies

description: We investigate the radio emission of ~185,000 quiescent (optically unclassifiable) galaxies selected from the Sloan Digital Sky Survey (SDSS). By median-stacking FIRST cutouts centered on the optically-selected sources, we are able to reach flux densities down to the 10s of microJy. The quiescent galaxy sample is composed of two subgroups inhabiting vastly different regimes: those targeted for the SDSS MAIN Galaxy Sample (~55%), and those targeted for the Luminous Red Galaxy (LRG) sample (~45%). To investigate the star-formation rates (SFRs) of these quiescent galaxies, we calibrate a radio-SFR conversion using a third sample of star-forming galaxies. Comparing this SFR-indicator with indicators in the optical and UV, we derive conflicting SFR estimates for the MAIN sample quiescent galaxies. These radio-derived SFRs intersect those calculated using the 4000-Angstrom break (D4000) around an SFR of 1 Msun/yr and agree to within a factor of 3 over the range of SFRs. However, we find that the radio-derived SFRs are too high relative to the SFRs estimated for similar populations of galaxies using analysis of UV emission, implying either contamination of the radio by Active Galactic Nuclei (AGN) or incomplete dust modeling. If AGN activity is dominant in these galaxies, then a relation between AGN radio luminosity and galaxy mass is required to explain the observed trends. For the LRGs, on the other hand, we find the radio luminosity to be independent of SFR as derived from D4000, indicating an AGN component dominates their radio emission. AGN-based radio emission often implies the existence of radio jets, providing evidence of a mechanism for low-level feedback in these quiescent LRGs. (Abridged)

description: We present low temperature tunneling density-of-states measurements in Al films in high parallel magnetic fields. The thickness range of the films, t=6-9 nm, was chosen so that the orbital and Zeeman contributions to their parallel critical fields were comparable. In this quasi-spin paramagnetically limited configuration, the field produces a significant suppression of the gap, and at high fields the gapless state is reached. By comparing measured and calculated tunneling spectra we are able to extract the value of the antisymmetric Fermi-liquid parameter G^0 and thereby deduce the quasiparticle density dependence of the effective parameter G^0_{eff} across the gapless state.

The validity and applicability of two modified cloze procedures (beginning of the page procedure and "instant" beginning of the page procedure) measured against the Stanford Diagnostic Reading Test and equated with the cloze procedure and Fry Readability Graph
Creators: name: Parkinson, Dianne
Publisher: name: University of British Columbia
Year: 2010

description: This correlational study examined the Beginning of the Page Procedure (B.O.P.P) and the "instant" Beginning of the Page Procedure as measures for assessing readability: One hundred ninety-six grade nine students (106 male and 90 female) took part in the study and their scores on the cloze procedure, the B.O.P.P. and the "instant" B.O.P.P. were correlated with the Stanford Diagnostic Reading Test Form A - Blue Level (hereafter referred to as the Stanford Diagnostic ). The Stanford Diagnostic was used as the anchor test and the students were randomly assigned to each of the three groups; Analyses included the calculation of means associated with the Stanford Diagnostic scores for each subgroup, and analysis of the variance between sexes within each subgroup. An equivalency table is provided which estimates the Stanford Diagnostic scores for a given cloze procedure, B.O.P.P. or "instant" B.O.P.P. score; Using the Stanford Diagnostic grade score equivalent to 40 percent on the cloze procedure, the readability level of the passage was determined. This was then compared to the readability level estimated by the Fry Graph. Respective correlations of .53 and .67 were found between the B.O.P.P. and "instant" B.O.P.P. with the Stanford Diagnostic suggesting both are good indicators of the students' ability to handle the given passage. Similarly the Fry Graph and the Stanford Diagnostic, grade score equal to 40 percent on the cloze procedure, found the passages to be at virtually the same level of difficulty. All results however, were limited to the passage studied and should not be generalized to other materials. When a significance level of .05 was used no significant difference was found between the male and female performance levels on any of the tests administered.
Multi-Lepton Production at High Transverse Momenta in ep Collisions at HERA

description: Processes leading to a final state with at least two high transverse momentum leptons (electrons or muons) are studied using the full ep data sample collected by the H1 experiment at HERA. The data correspond to an integrated luminosity of 463 pb-1. Di-lepton and tri-lepton event classes are investigated. Cross sections of the production of e+e- and mu+mu- pairs are derived in a restricted phase space dominated by photon-photon collisions. In general, good agreement is found with Standard Model predictions. Events are observed with a total scalar sum of lepton transverse momenta above 100 GeV where the Standard Model expectation is low. In this region, combining di-lepton and tri-lepton classes, five events are observed in e+p collisions, compared to a Standard Model expectation of 0.96+-0.12, while no such event is observed in e-p data for 0.64+-0.09 expected.

description: This study presents methods called TSGPR- and SAC-SketchyCoreSVD to improve the protocol of subsampling data fibers for building random sketches and low rank SVD of a data matrix by formulating them as a sequential decision making problem. An agent progressively decides which data fibers to subsample next to maximize the accuracy of low rank SVD under the limited computational resources. Using the information coming from the partially observed data matrix constructed by subsampled fibers so far, methods learn the optimal policy. Thompson sampling and Gaussian process regression are used for TSGPR-SketchyCoreSVD, and Soft Actor-Critic is applied to SAC-SketchyCoreSVD. Experiments show TSGPR-SketchyCoreSVD actively learns the subsampling policy and produces higher accuracy than the original SketchyCoreSVD. SAC-SketchyCoreSVD is still developing, but its intermediate result also shows promising results. This study can be easily expanded to higher order data tensors.

description: We report on the discovery of three new dwarf galaxies in the Local Group. These galaxies are found in new CFHT/MegaPrime g,i imaging of the south-western quadrant of M31, extending our extant survey area to include the majority of the southern hemisphere of M31's halo out to 150 kpc. All these galaxies have stellar populations which appear typical of dwarf spheroidal (dSph) systems. The first of these galaxies, Andromeda XVIII, is the most distant Local Group dwarf discovered in recent years, at ~1.4 Mpc from the Milky Way (~ 600 kpc from M31). The second galaxy, Andromeda XIX, a satellite of M31, is the most extended dwarf galaxy known in the Local Group, with a half-light radius of r_h ~ 1.7 kpc. This is approximately an order of magnitude larger than the typical half-light radius of many Milky Way dSphs, and reinforces the difference in scale sizes seen between the Milky Way and M31 dSphs (such that the M31 dwarfs are generally more extended than their Milky Way counterparts). The third galaxy, Andromeda XX, is one of the faintest galaxies so far discovered in the vicinity of M31, with an absolute magnitude of order M_V ~ -6.3. Andromeda XVIII, XIX and XX highlight different aspects of, and raise important questions regarding, the formation and evolution of galaxies at the extreme faint-end of the luminosity function. These findings indicate that we have not yet sampled the full parameter space occupied by dwarf galaxies, although this is an essential pre-requisite for successfully and consistently linking these systems to the predicted cosmological dark matter sub-structure.

Sparse image reconstruction for molecular imaging

description: The application that motivates this paper is molecular imaging at the atomic level. When discretized at sub-atomic distances, the volume is inherently sparse. Noiseless measurements from an imaging technology can be modeled by convolution of the image with the system point spread function (psf). Such is the case with magnetic resonance force microscopy (MRFM), an emerging technology where imaging of an individual tobacco mosaic virus was recently demonstrated with nanometer resolution. We also consider additive white Gaussian noise (AWGN) in the measurements. Many prior works of sparse estimators have focused on the case when H has low coherence; however, the system matrix H in our application is the convolution matrix for the system psf. A typical convolution matrix has high coherence. The paper therefore does not assume a low coherence H. A discrete-continuous form of the Laplacian and atom at zero (LAZE) p.d.f. used by Johnstone and Silverman is formulated, and two sparse estimators derived by maximizing the joint p.d.f. of the observation and image conditioned on the hyperparameters. A thresholding rule that generalizes the hard and soft thresholding rule appears in the course of the derivation. This so-called hybrid thresholding rule, when used in the iterative thresholding framework, gives rise to the hybrid estimator, a generalization of the lasso. Unbiased estimates of the hyperparameters for the lasso and hybrid estimator are obtained via Stein's unbiased risk estimate (SURE). A numerical study with a Gaussian psf and two sparse images shows that the hybrid estimator outperforms the lasso.

description: We study whether spin-independent scattering of weakly-interacting massive particles (WIMPs) with nuclei can account for the annual modulation signal reported by DAMA. We consider both elastic and inelastic scattering processes. We find that there is a region of WIMP parameter space which can simultaneously accommodate DAMA and the null results of CDMS, CRESST, and XENON. This region corresponds to an ordinary, elastically-scattering WIMP with a standard Maxwell-Boltzmann distribution, a mass 3 GeV < m_{DM} <8 GeV, and a spin-independent cross section with nucleons 3 \times 10^{-41} cm^2 < σ_p^{SI} < 5 \times 10^{-39} cm^2. This new region of parameter space depends crucially on the recently discovered effect of channeling on the energy threshold for WIMP detection in the DAMA experiment; without the inclusion of this effect, the DAMA allowed region is essentially closed by null experiments. Such low-mass WIMPs arise in many theories of Beyond the Standard Model physics, from minimal extensions of the MSSM to solutions of the baryon-dark matter coincidence problem. We find that inelastic scattering channels do not open up a significant parameter region consistent with all experimental results. Future experiments with low energy thresholds for detecting nuclear recoils, such as CDMSII-Si and those utilizing ultra-low energy germanium detectors, will be able to probe the DAMA region of parameter space.

description: The binding of a transcription factor (TF) to a DNA operator site can initiate or repress the expression of a gene. Computational prediction of sites recognized by a TF has traditionally relied upon knowledge of several cognate sites, rather than an ab initio approach. Here, we examine the possibility of using structure-based energy calculations that require no knowledge of bound sites but rather start with the structure of a protein-DNA complex. We study the PurR E. coli TF, and explore to which extent atomistic models of protein-DNA complexes can be used to distinguish between cognate and non-cognate DNA sites. Particular emphasis is placed on systematic evaluation of this approach by comparing its performance with bioinformatic methods, by testing it against random decoys and sites of homologous TFs. We also examine a set of experimental mutations in both DNA and the protein. Using our explicit estimates of energy, we show that the specificity for PurR is dominated by direct protein-DNA interactions, and weakly influenced by bending of DNA.

description: The low-energy scattering properties of two aligned identical bosonic and identical fermionic dipoles are analyzed. Generalized scattering lengths are determined as functions of the dipole moment and the scattering energy. Near resonance, where a new bound state is being pulled in, all non-vanishing generalized scattering lengths diverge, with the $a_{00}$ and $a_{11}$ scattering lengths being dominant for identical bosons and identical fermions, respectively, near both broad and narrow resonances. Implications for the energy spectrum and the eigenfunctions of trapped two-dipole systems and for pseudo-potential treatments are discussed.

Establishing the Value of DER to the Grid - This presentation focuses on a method is proposed to compute the Locational Marginal Value (LMV) of DER active (kW) and reactive (kVar) power contribution to the grid in terms of avoided cost as a Non-Wires Alternative.

Economic, Reliability and Resilience Considerations for TE Systems - This presentation discusses factors to consider for deployment of Transactive Energy Systems (TES) with a view to the values TE can create under varying grid conditions.

From Airbnb to Solar: Toward a Transaction cost model of a Retail Electricity Dist Platform - Here we propose a two-stage transaction cost model to represent the effects of transaction cost-reducing innovation on two aspects of such transactions: gains from trade in sharing, and the margin that divides renters from owners. We analyze the equilibrium comparative statics of the model to derive observable predictions, and find that the rental market option makes the opportunity cost of excess capacity salient.

Distribution System Operator Models for Utility Stakeholders - DSO Organizational Models for a Digital, Distributed Modern Grid - The result of having wholesale markets and creating a competitive landscape has had numerous benefits, including lower energy costs to end consumers and more reliable energy delivery. But, the other, equally important effect is the innovation that has occurred due to having a market in which to compete. The results have manifested as more efficient and cleaner power plants, new software applications, better control systems, and new optimization solutions.
An exploratory study of Egan’s four stages of educational development and their application to curriculum design in physical education
Creators: name: Schueler, Annemarie
Publisher: name: University of British Columbia
Year: 2010

description: This study explored the possibility of structuring physical education curriculum utilizing Kieran Egan's educational development theory. It began with the premise that too often eclectic or non-theoretical approaches to curriculum design have resulted in fragmentary, inconsistent, activity programs. Although recent approaches to program planning at both the elementary secondary level are characterized by a great deal of diversity, they seem to lack an educational developmental perspective. The study examines the role developmental theories have played in physical education curriculum design and in particular that of Piaget"s theory of cognitive development. Research is cited to indicate the limitations of Piaget's developmental theory, in terms of designing physical education.curricula. Egan's theory of educational development is articulated and a comparison is drawn between a psychological theory such as Piaget's and an educational theory such as Egan's. Egan's original and comprehensive educational theory outlines four developmental stages: mythic, romantic, philosophic, and ironic. The stages span the years from 4 to maturity. Educational aspects of development such as learning and motivation are dealt with through the characteristics of different stages which in turn lead directly to principles for organizing curriculum. With its educational orientation, the theory focuses upon four questions to which educators are interested in finding answers: What should our end-product be like? What should we teach? When should we teach? How should we teach? His theory is pervaded with the question of the appropriateness of structuring subject matter to each developmental stage and with making connections from stage to stage to provide optimal growth through the entire educational process. Utilizing the principles derived from each of the four stages, the study explores ways of structuring physical education curriculum. Application of the theory at each stage is discussed in terms of three broad activity areas: dance, gymnastics, and games. Egan's theory provides us with guidelines as to how best we might go about structuring activities and which particular activities might be most educationally suitable at each stage. In summary, the study suggests that Egan's theory of educational development can offer the physical education curriculum planner a more meaningful educational-oriented paradigm from which to plan programs from kindergarten to grade twelve. Utilizing the main principles of Egan's theory will help structure more coherent developmental programs in the three domains of: affective development, cognitive development, and psychomotor development. Egan's theory appears to open new doors for designing physical education curricula.

description: It is well known that the subvariety lattice of the variety of relation algebras has exactly three atoms. The (join-irreducible) covers of two of these atoms are known, but a complete classification of the (join-irreducible) covers of the remaining atom has not yet been found. These statements are also true of a related subvariety lattice, namely the subvariety lattice of the variety of semiassociative relation algebras. The present article shows that this atom has continuum many covers in this subvariety lattice (and in some related subvariety lattices) using a previously established term equivalence between a variety of tense algebras and a variety of semiassociative r-algebras.
