description: We study the evolution of linear perturbations in metric f(R) models of gravity and identify a potentially observable characteristic scale-dependent pattern in the behavior of cosmological structures. While at the background level viable f(R) models must closely mimic LCDM, the differences in their prediction for the growth of large scale structures can be sufficiently large to be seen with future weak lensing surveys. While working in the Jordan frame, we perform an analytical study of the growth of structures in the Einstein frame, demonstrating the equivalence of the dynamics in the two frames. We also provide a physical interpretation of the results in terms of the dynamics of an effective dark energy fluid with a non-zero shear. We find that the growth of structure in f(R) is enhanced, but that there are no small scale instabilities associated with the additional attractive "fifth force". We then briefly consider some recently proposed observational tests of modified gravity and their utility for detecting the f(R) pattern of structure growth.

description: In this work, we establish a few exact identities through commutation of intra-orbital and inter-orbital on-site pairings with a two-orbital model describing newly discovered FeAs-based superconductors. Applying the conclusion drawn from rigorous relation and physical interpretation, we give constraints on the possible symmetries of the superconducting pairing of the model. Hence the favorable pairings in newly discovered high-temperature oxypnictide superconductors are proposed.

description: Gravitational waveforms and fluxes from extreme mass--ratio inspirals can be computed using time--domain methods with accuracy that is fast approaching that of frequency--domain methods. We study in detail the computational efficiency of these methods for equatorial orbits of fast spinning Kerr black holes, and find the number of modes needed in either method --as functions of the orbital parameters-- in order to achieve a desired accuracy level. We then estimate the total computation time and argue that for high eccentricity orbits the time--domain approach is more efficient computationally. We suggest that in practice low--$m$ modes are computed using the frequency--domain approach, and high--$m$ modes are computed using the time--domain approach, where $m$ is the azimuthal mode number.

description: We analyse the static solutions of attractive Bose-Einstein condensates under transverse confinement, both with and without axial confinement. By full numerical solution of the Gross-Pitaevskii equation and variational methods we map out the condensate solutions, their energetic properties, and their critical points for instability. With no axial confinement a bright solitary wave solution will tend to decay by dispersion unless the interaction energy is close to the critical value for collapse. In contrast, with axial confinement the only decay mechanism is collapse. The stability of a bright solitary wave solution increases with higher radial confinement. Finally we consider the stability of dynamical states containing up to four solitons and find good agreement with recent experiments.

Virtual Summation Meters in Smart Grids
Learning objectives-
1.	To understand the concept of virtual energy meters.
2.	To understand the concept of virtual summation meters.
3.	To understand the significant role of summation meters in smart grids.  The summation meters perform summation of consumptions recorded by meters provided at outgoing feeders emanating from bus at substations in smart grids. The convention meters are physical meters. In the advent of Virtual Summation Meters, entire meter data can be visualized on computers. Thus, the utility engineer can monitor this data on his or her laptop or mobile phone from any place in the world. The virtual energy meters are basically IoT enabled meters. The summation of consumptions is performed using Python TensorFlow libraries.   Given the ongoing transition towards a more decentralised energy system, the potential of blockchain-enabled smart contracts for the energy sector is being increasingly recognised. Due to their self-executing and tamper-proof nature, they are a key technology for enabling the transition to a more efficient, transparent and transactive energy market. Their applications include coordination of smart electric vehicle charging, automated demand-side response, peer-to-peer energy trading and allocation of control duties amongst the network operators. Nevertheless, their use in the energy sector is still in its early stages as there are many challenges related to security and scalability. In this webinar, we reflect our findings from the systematic review of 178 peer-reviewed publications and 13 innovation projects. This webinar offers a broad perspective on the opportunities and challenges that stakeholders using this technology face, in current and emergent markets. We demonstrate a systematic model of the smart contracting process, by using our novel 6-layer architecture, and share our open-source sample energy contract code. We focus on two mainstream application areas identified as; energy and flexibility trading, and distributed control. The webinar concludes with a critical discussion of the challenges and a set of recommendations that researchers should consider when applying smart contracts in energy systems.

description: Holczer, Mazeh, and collaborators (HM+16) used the Kepler four-year observations to derive a transit-timing catalog, identifying 260 Kepler objects of interest (KOI) with significant transit timing variations (TTV). For KOIs with high enough SNRs, HM+16 also derived the duration and depth of their transits. In the present work, we use the duration measurements of HM+16 to systematically study the duration changes of 561 KOIs and identify 15 KOIs with a significant long-term linear change of transit durations and another 16 KOIs with an intermediate significance. We show that the observed linear trend is probably caused by a precession of the orbital plane of the transiting planet, induced in most cases by another planet. The leading term of the precession rate depends on the mass and relative inclination of the perturber, and the period ratio between the two orbits, but not on the mass and period of the transiting planet itself. Interestingly, our findings indicate that, as a sample, the detected time derivatives of the durations get larger as a function of the planetary orbital period, probably because short-period planetary systems display small relative inclinations. The results might indicate that short-period planets reside in relatively flattened planetary systems, suggesting these systems experienced stronger dissipation either when formed or when migrated to short orbits. This should be used as a possible clue for the formation of such systems.

description: Let d1,...,dn be a strictly increasing sequence of integers. Boij and Söderberg [arXiv:math/0611081] have conjectured the existence of a graded module M of finite length over any polynomial ring K[x_1,..., x_n], whose minimal free resolution is pure of type (d1,...,dn), in the sense that its i-th syzygies are generated in degree di. In this paper we prove a stronger statement, in characteristic zero: Such modules not only exist, but can be taken to be GL(n)-equivariant. In fact, we give two different equivariant constructions, and we construct pure resolutions over exterior algebras and Z/2-graded algebras as well. The constructions use the combinatorics of Schur functors and Bott's Theorem on the direct images of equivariant vector bundles on Grassmann varieties.

Magnetic resonance studies of atomic hydrogen confined by solid molecular hydrogen between 6.4 and 8.2 k
Creators: name: Steel, Stephen Chris
Publisher: name: University of British Columbia
Year: 2010

description: Magnetic hyperfine resonance in zero magnetic field has been used to study atomic hydrogen gas confined by walls coated with solid molecular hydrogen at temperatures between 6.4 and 8.2 K. The temperature range of the experiments was limited by the nature of the atom source used to produce atoms. Measurements of the frequency shift at low atom densities (nH ≃ 8 x l0⁺¹⁶ m⁻³) have yielded a binding energy for H on H₂ of 34.04 ± 0.26 K, and a surface frequency shift of -1.16 ± 0.05 MHz. These results are in excellent agreement with those obtained by Crampton et al between 3.2 and 4.5 K. The pressure shift due to the vapour pressure of the solid H₂ was found to be -1.78 ± 0.01 x 10⁻²⁴ Hz m³. The low atom density transverse relaxation rate measurements are difficult to interpret. There seems to be a relaxation mechanism on the H₂ surface that gives a contribution beyond that associated with the dispersion of frequency shifts an atoms see from normal adsorption. The data does show that the sticking coefficent of H on H₂ is greater than 0.04. Measurements at higher atom densities (nH ≤ 9 x 10⁺¹⁸ m⁻³) gave values for the surface recombination cross length which increased from 0.5 A at 6.4 K to 1.1 A at 8.2 K. The bulk spin exchange cross section was found to agree quite well with the calculations of Berlinsky and Shizgal.

description: Algorithm selection is typically based on models of algorithm performance, learned during a separate offline training sequence, which can be prohibitively expensive. In recent work, we adopted an online approach, in which a performance model is iteratively updated and used to guide selection on a sequence of problem instances. The resulting exploration-exploitation trade-off was represented as a bandit problem with expert advice, using an existing solver for this game, but this required the setting of an arbitrary bound on algorithm runtimes, thus invalidating the optimal regret of the solver. In this paper, we propose a simpler framework for representing algorithm selection as a bandit problem, with partial information, and an unknown bound on losses. We adapt an existing solver to this game, proving a bound on its expected regret, which holds also for the resulting algorithm selection technique. We present preliminary experiments with a set of SAT solvers on a mixed SAT-UNSAT benchmark.

A novel method for assessing microplastic effect in suspension through mixing test and reference materials.

description: The occurrence of microplastic in the environment is of global concern. However, the microplastic hazard assessment is hampered by a lack of adequate ecotoxicological methods because of conceptual and practical problems with particle exposure. In the environment, suspended solids (e.g., clay and cellulose) in the same size range as microplastic, are ubiquitous. Therefore, it must be established whether the addition of microplastic to these background levels of particulate material represents a hazard. We present a novel approach employing a serial dilution of microplastic and reference particles, in mixtures, which allows disentangling the effect of the microplastic from that of the other particulates. We demonstrate the applicability of the method using an immobilization test with Daphnia magna exposed to polyethylene terephthalate (test microplastic; median particle diameter ~5 μm) and kaolin clay (reference material; ~3 μm). In the range of the suspended solids test concentrations (0–10 000 mg L−1), with microplastic contributing 0–100% of total mass, the LC50 values for the plastic mixtures were significantly lower compared to the kaolin exposure. Hence, the exposure to polyethylene terephthalate was more harmful to the daphnids than to the reference material alone. The estimated threshold for the relative contribution of the test microplastic to suspended matter above which significantly higher mortality was observed was 2.4% at 32 mg of the solids L−1. This approach has a potential for standardization of ecotoxicological testing of particulates, including microplastic.

description: Fiber-fed etalons are widely employed in advanced interferometric instruments such as gravitational-wave detectors, ultrastable lasers and calibration reference for high-precision spectrographs. We demonstrate that variation in near-field distribution of the feeding fiber would deteriorate the spectrum precision of the fiber-fed Fabry-Perot etalon, especially when precision at the order of 3 * 10-10 or higher is required. The octagonal fiber reinforced with double scrambler could greatly improve the steadiness and uniformness of the near-field distribution. When building wavelength calibrators for sub-m s-1 precision radial-velocity instruments, the double scrambler should be considered meticulously.

A morphological and cytological study of Audouinella porphyrae and A. vaga (Rhodophyta)
Creators: name: Tam, Carol Elizabeth

Year: 2010

description: A comparative study was made between two similar red algal endophytes, Audouinella porphyrae (Drew) Garbary and Audouinella vaga (Drew) Garbary, Hansen et Scagel, (Acrochaetiaceae, Acrochaetiales) and their red algal hosts Porphyra spp. and Pterosiphonia bipinnata, respectively. Both endophytes have axial, stellate chloroplasts with a central pyrenoid and reside in their host's cell walls, producing erect portions outside the host that may bear monosporangia. The endophytes were cultured "free" from their hosts and morphological and cytological features of the free-living forms were compared with field material. Although the two endophytes differ significantly in cell dimensions and branching patterns, the free-living forms do not retain these differences. Cell dimensions, branching patterns and developmental patterns are identical in the two free-living forms. Asexual reproduction with regeneration by monospores was observed. Sexual reproduction was not observed in either endophytic or free-living forms of the endophytes. Free-living forms were used for re-infection and cross-infection experiments. Under all experimental conditions, the endophytes showed only epiphytic growth. The hosts seem to have some effect on both of the endophytes. Epiphytes, Audouinella porphyrae and A. vaga were not selective and grew on both hosts, Porphyra torta and Pterosiphonia bipinnata. Both epiphtyes growing on blades of Porphyra tended to branch and have more extensive prostrate portions (3-5 cells) whereas both epiphytes on Pterosiphoni a bipinnata tend not to branch and have only 1-2 cells in the prostrate portions. Ultrastructural studies of both endophytes showed typical florideophycean features. Ultrastructural features of field material of the two endophytes were similar and free-living, cultured endophytes were similar to field material. A large vacuole was observed in sections of the field material of both prostrate and erect portions whereas this was not observed in cultured material. Based on the results of this study it is proposed that the two endophytes are conspecific. Audouinella vaga is referred to synonymy in Audouinella porphyrae (Drew) Garbary, Hansen et Scagel.

description: We present a Chandra X-ray observation of G12.82-0.02, a shell-like radio supernova remnant coincident with the TeV gamma-ray source HESS J1813-178. We resolve the X-ray emission from the co-located ASCA source into a point source surrounded by structured diffuse emission that fills the interior of the radio shell. The morphology of the diffuse emission strongly resembles that of a pulsar wind nebula. The spectrum of the compact source is well-characterized by a power-law with index Gamma approx 1.3, typical of young and energetic rotation-powered pulsars. For a distance of 4.5 kpc, consistent with the X-ray absorption and an association with the nearby star formation region W33, the 2-10 keV X-ray luminosities of the putative pulsar and nebula are L(PSR) = 3.2E33 ergs/s and L(PWN) = 1.4E34 ergs/s, respectively. Both the flux ratio of L(PWN)/L(PSR) = 4.3 and the total luminosity of this system predict a pulsar spin-down power of Edot > 1E37 ergs/s, placing it within the ten most energetic young pulsars in the Galaxy. A deep search for radio pulsations using the Parkes telescope sets an upper-limit of approx 0.07 mJy at 1.4 GHz for periods >~ 50 ms. We discuss the energetics of this source, and consider briefly the proximity of bright H2 regions to this and several other HESS sources, which may produce their TeV emission via inverse Compton scattering.

Investigations into dysglycaemia and ethnic health disparities using mass spectrometry based plasma proteomics and targeted assay analysis
Creators: name: Pearsey, Harriet M.

description: Background:Mass Spectrometry (MS) - proteomics is emerging in diabetes research. Ethnicity is an important factor in the development of dysglycaemia, with South Asians (SA) in particular at increased risk. The use of MS-proteomics to compare ethnic differences in dysglycaemia is under-researched and may aid in understanding disease aetiology.Aims:1. To investigate differences in the fasting proteomes of white European (WE) and SA adults with either normal glycaemic control or non-diabetic hyperglycaemia.2. To verify and validate the identified proteins to confirm differences.3. To quantify the role of the verified protein(s) in dysglycaemia in existing literature4. To examine associations of the protein(s) with energy expenditure (EE) and consumption of a plant-based diet.5. To investigate differences in the post-prandial proteomes of WE and SA adults in response to an acute physical activity intervention.Key findings:1. MS-proteomic analysis identified zinc-alpha-2-glycoprotein (ZAG) as being lower in SA versus WE and lower in individuals with NDH versus NGC.2. Targeted verification/validation analyses ZAGs confirmed differences between WE and SA individuals but not glycaemic control.3. The current literature demonstrates that circulating ZAG was lower in dysglycaemic individuals but this was attenuated after body mass index adjustment.4. ZAG was inversely associated with exercise-related EE and adopting a plant-based diet resulted in lower ZAG.5. Post-prandial proteome analysis identified 60 proteins that may explain mechanisms for disease-risk differences between ethnicities, in response to physical activity and ethnicity/physical activity interaction.Conclusions:Fasting proteomic differences were explored in WEs and SAs and differing level of dysglycaemia, highlighting ZAG as a protein of interest. Associations between ZAG and lifestyle factors relating to glycaemic control were then explored. The post-prandial proteome of WE and SA adults was also investigated to determine protein mechanisms for ethnic health disparities and responses to physical activity.

description: Pure t-motives were introduced by G. Anderson as higher dimensional generalizations of Drinfeld modules, and as the appropriate analogs of abelian varieties in the arithmetic of function fields. In order to construct moduli spaces for pure t-motives the second author has previously introduced the concept of abelian τ-sheaf. In this article we clarify the relation between pure t-motives and abelian τ-sheaves. We obtain an equivalence of the respective quasi-isogeny categories. Furthermore, we develop the elementary theory of both structures regarding morphisms, isogenies, Tate modules, and local shtukas. The later are the analogs of p-divisible groups.

description: We construct a new exactly solvable supersymmetric spin chain related to the BC_N extended root system, which includes as a particular case the BC_N version of the Polychronakos-Frahm spin chain. We also introduce a supersymmetric spin dynamical model of Calogero type which yields the new chain in the large coupling limit. This connection is exploited to derive two different closed-form expressions for the chain's partition function by means of Polychronakos's freezing trick. We establish a boson-fermion duality relation for the new chain's spectrum, which is in fact valid for a large class of (not necessarily integrable) spin chains of BC_N type. The exact expressions for the partition function are also used to study the chain's spectrum as a whole, showing that the level density is normally distributed even for a moderately large number of particles. We also determine a simple analytic approximation to the distribution of normalized spacings between consecutive levels which fits the numerical data with remarkable accuracy. Our results provide further evidence that spin chains of Haldane-Shastry type are exceptional integrable models, in the sense that their spacings distribution is not Poissonian, as posited by the Berry-Tabor conjecture for "generic'' quantum integrable systems.

SEM
Diapausing embryos were ovoid and measured ca 134 µm in diameter (̄x = 134.0 ± 4.0 μm). The outer surface was composed of numerous smooth ridges and wrinkles, creating an overall rough surface (Figure 2a,b).
TEM
The shell consisted of a thick apical layer and a thin basal layer. Average shell thickness was 2.30 ± 0.22 µm (SD). The outer layer, termed the alveolar layer by Munuswamy et al. (1996), had a wavy texture (Figure 2c,d). Electron density was highest at the topmost and bottom portions of the alveolar layer, otherwise it had a similar electron density throughout its thickness and contained many ̍empty̾ pockets that were interconnected through electron-dense bridges. The basal layer [s1 of Munuswamy et al. (1996)] had an amorphous appearance that consisted of an electron lucent zone and a more electron-opaque zone below it (Figure 2d). Thin fibres were present throughout both zones.
AFM
Topography of the outer shell showed rugosity and similar attributes to those in SEM, but with fewer details (Figure 2e). An example force–distance curve that displays how Young̾s modulus values were collected for a single spot on one egg is shown in Figure 2f. The Young̾s modulus ranged from 12.24 to 19.85 MPa with an average of 15.81 ± 2.49 MPa (SD) (Table 1). Hardness values ranged from 1.14 × 10−2 to 5.31 × 10−2 GPa with an average hardness of 1.853 × 10−2 ±1.23 × 10−2 GPa (Table 2).

A model of Islamic teacher education for social justice in Indonesia a critical pedagogy perspective
Creators: name: Raihani Raihani

Subjects: Uncategorized

description: © 2020, State Islamic University of Sunan Ampel. All rights reserved. This paper proposes a model for teacher preparation in the context of Islamic education using a critical pedagogy perspective. The constantly increasing social injustice combined with sectarian frictions has placed Indonesian society in a fragile situation and, it, therefore, needs a closer attention, and more so in the field of education. This paper argues that reforms in education should begin from the very vital component of education, i.e. teacher since teacher contributes significantly to the development of students in almost all aspects. Also, the traditional approach of instruction does not seem able to provide solutions for most of the social problems, even though Islamic teachings strongly endorse equality, justice, and respect for differences. This conceptual paper, therefore, develops a model for reforms in teacher education starting from philosophical foundation of teaching to critical pedagogy practices. In this paper, this critical pedagogy approach is argued to enable teachers to become change agents for promoting education for social justice.

Topography of the outer shell displayed comparable morphologies to those visualised with SEM, but with more texture observed under AFM (Figure 3c). Small bumps ranging in size from 0.3 to 1.1 µm were present on the surface. An example force–distance curve that displays how Young̾s modulus values were collected for a single spot on one egg is shown in Figure 3d. The average Young̾s modulus ranged from 17.40 to 22.51 MPa with a mean of 20.93 ± 1.57 MPa (SD) (Table 1). Hardness values ranged from 1.90 × 10−2 GPa to 2.43 × 10−2 GPa with a mean hardness of 2.20 × 10−2 GPa ± 1.67 × 10−3 GPa (SD) (Table 2).

description: Desingularized fiber products of semi-stable, non-isotrivial jacobian elliptic surfaces with vanishing third Betti number are classified. Such varieties may play a role in the study of supersingular threefolds, of the deformation theory of varieties with trivial canonical bundle, and of the arithmetic degenerations of rigid Calabi-Yau threefolds.

description: We construct a new holographic description of QCD using domain wall fermions. The construction consists of probe D7 branes in a D5 brane geometry describing quarks on a 4+1d defect in a 5+1d gauge theory. We then compactify one dimension of the D5 to introduce confinement in the gauge degrees of freedom. In addition we allow a spatial dependent mass term for the D7 brane quarks to isolate chiral fermions on 3+1d domain walls. The D7 world volume fields, when restricted to the domain wall position, provide an AdS/QCD description. We compute the spectrum and compare to data. We include higher dimension operators to systematically improve the description.

description: This document provides a survey over vocabularies for language resources and services and sketch necessary extensions and the expected contribution of the Prêt-à-LLOD project to their further development for phenomena currently not sufficiently covered. Future updates with respect to this will be documented within Task 5.4.

 We focus on three main aspects of linguistically analyzed data
 1. lexical-conceptual resources, i.e., repositories of terminology, lexical data, translation, and semantics,
 2. linguistically annotated data, concerning linguistic analysis of textual or transcribed data, and
 3. language resource terminology, i.e., linguistic data categories and metadata

 For these areas, we describe representative vocabularies from the Linguistic Linked Open Data community (RDF-based vocabularies) as well as other approaches (e.g., ISO TC37 standards), we identify a number of gaps, and we describe ongoing efforts to address these
 gaps within the Prêt-à-LLOD project.

description: We present a simplest inflationary scenario in the minimal left-right symmetric model with spontaneous D-parity breaking, which is a well motivated particle physics model for neutrino masses. This leads us to connect the observed anisotropies in the cosmic microwave background to the sub-eV neutrino masses. The baryon asymmetry via the leptogenesis route is also discussed briefly.

Semiparametric efficiency in GMM models with auxiliary data

description: We study semiparametric efficiency bounds and efficient estimation of parameters defined through general moment restrictions with missing data. Identification relies on auxiliary data containing information about the distribution of the missing variables conditional on proxy variables that are observed in both the primary and the auxiliary database, when such distribution is common to the two data sets. The auxiliary sample can be independent of the primary sample, or can be a subset of it. For both cases, we derive bounds when the probability of missing data given the proxy variables is unknown, or known, or belongs to a correctly specified parametric family. We find that the conditional probability is not ancillary when the two samples are independent. For all cases, we discuss efficient semiparametric estimators. An estimator based on a conditional expectation projection is shown to require milder regularity conditions than one based on inverse probability weighting.

description: We show that recent determinant evaluations involving Catalan numbers and generalisations thereof have most convenient explanations by combining the Lindström-Gessel-Viennot theorem on non-intersecting lattice paths with a simple determinant lemma from [Manuscripta Math. 69 (1990), 173-202]. This approach leads also naturally to extensions and generalisations.

Flux distribution in metabolic networks close to optimal biomass production

Publisher: name: arXiv

Subjects: subject: Molecular Networks (q-bio.MN)

description: We study a statistical model describing the steady state distribution of the fluxes in a metabolic network. The resulting model on continuous variables can be solved by the cavity method. In particular analytical tractability is possible solving the cavity equation over an ensemble of networks with the same degree distribution of the real metabolic network. The flux distribution that optimizes production of biomass has a fat tail with a power-law exponent independent on the structural properties of the underling network. These results are in complete agreement with the Flux-Balance-Analysis outcome of the same system and in qualitative agreement with the experimental results.

In particular, mock galaxy catalogs are a crucial resource to achieve these goals in the measurement of baryon acoustic oscillation (BAO) in the clustering of galaxies. Here we present a set of 1952 galaxy mock catalogs designed to mimic the Dark Energy Survey (DES) Year 3 BAO sample over its full photometric redshift range $0.6

description: We construct a solution of eleven dimensional supergravity corresponding to a stack of M2 branes localized at the center of a particular eight dimensional hyper-Kaehler manifold constructed by Gauntlett, Gibbons, Papadopoulos, and Townsend, generalizing the earlier construction of Cherkis and Hashimoto. In the decoupling limit, this solution is dual to a Chern-Simons/Yang-Mills/Matter theory in 2+1 dimensions with N=3 supersymmetry, which flows in the infra red to a superconformal Chern-Simons/Matter system preserving N=6,8 supersymmetry, constructed recently by Aharony, Bergman, Jafferis, and Maldacena.

description: We prove that the Cox ring of $\bar{M}_{0,6}$, the moduli space of stable, rational curves with 6 marked points, is finitely generated by sections corresponding to the boundary divisors and divisors which are pull-backs of the hyperelliptic locus in $\bar{M}_3$, the moduli space of stable, genus 3 curves, via morphisms that send a 6-pointed rational curve to a curve with 3 nodes by identifying 3 pairs of points. In particular, this gives a self-contained proof of Hassett and Tschinkel's result about the effective cone of $\bar{M}_{0,6}$ being generated by the above mentioned divisors.
