description: Asymmetric dots as a function of their geometry have been investigated using three-dimensional (3D) object oriented micromagnetic framework (OOMMF) code. The effect of shape asymmetry of the disk on coercivity and remanence is studied. Angular dependence of the remanence and coercivity is also addressed. Asymmetric dots are found to reverse their magnetization by nucleation and propagation of a vortex, when the field is applied parallel to the direction of asymmetry. However, complex reversal modes appear when the angle at which the external field is applied is varied, leading to a non monotonic behavior of the coercivity and remanence.

Grids of ATLAS9 Model Atmospheres and MOOG Synthetic Spectra
Creators: name: Kirby, Evan N.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: A grid of ATLAS9 model atmospheres has been computed, spanning 3500 K <= T_eff <= 8000 K, 0.0 <= log g <= 5.0, -4.0 <= [M/H] <= 0.0, and -0.8 < [alpha/Fe] <= +1.2. These parameters are appropriate for stars in the red giant branch, subgiant branch, and the lower main sequence. The main difference from a previous, similar grid (Castelli & Kurucz 2003) is the range of [alpha/Fe] values. A grid of synthetic spectra, calculated from the model atmospheres, is also presented. The fluxes are computed every 0.02 Angstrom from 6300 Angstrom to 9100 Angstrom. The microturbulent velocity is given by a relation to the surface gravity. This relation is appropriate for red giants, but not for subgiants or dwarfs. Therefore, caution is urged for the synthetic spectra with log g > 3.5 or for any star that is not a red giant. Both the model atmosphere and synthetic spectrum grids are available online through VizieR. Applications of these grids include abundance analysis for large samples of stellar spectra and constructing composite spectra for stellar populations.

description: New Chandra X-ray data and extensive optical spectroscopy, obtained with AAOmega on the 3.9 m Anglo-Australian Telescope, are used to study the complex merger taking place in the galaxy cluster Abell 2744. Combining our spectra with data from the literature provides a catalog of 1237 redshifts for extragalactic objects lying within 15' of the cluster center. From these, we confirm 343 cluster members projected within 3 Mpc of the cluster center. Combining positions and velocities, we identify two major substructures, corresponding to the remnants of two major subclusters. The new data are consistent with a post core passage, major merger taking place along an axis that is tilted well out of the plane of the sky, together with an interloping minor merger. Supporting this interpretation, the new X-ray data reveal enriched, low entropy gas from the core of the approaching, major subcluster, lying ~2' north of the cluster center, and a shock front to the southeast of the previously known bright, compact core associated with the receding subcluster. The X-ray morphology of the compact core is consistent with a Bullet-like cluster viewed from within ~45 degrees of the merger axis. An X-ray peak ~3' northwest of the cluster center, with an associated cold front to the northeast and a trail of low entropy gas to the south, is interpreted as the remnant of an interloping minor merger taking place roughly in the plane of the sky. We infer approximate paths for the three merging components.

Integrative and theoretical reviews of achievement motivation for school psychologists: Introduction to the special issue
Creators: Daniels, Lia M.
Dueck, Bryce S.
Publisher: name: University of Alberta Library
Year: 2022

Although school psychologists have a wide range of expertise, generally speaking theories of motivation. The papers in this special issue were selected for their focus specifically on the integration of theories of achievement motivation to the practice of school psychology Among their various roles, school psychologists are tasked with evaluating students’ cognitive abilities, academic achievement, and emotional/behavioural functioning and then attending to current dysfunction or implementing preventative measures (Canadian Psychological Association, 2016). They also serve as consultants to teachers, parents, administrative staff, and other inclusive learning professionals (Canadian Psychological Association, 2016). They bring expertise in assessment, intervention, and child development to bear on the complex learning needs of the students and their school systems. Despite this high level of expertise, a theoretically grounded understanding of achievement motivation appears to be largely overlooked in both initial education programmes and ongoing professional development (Cleary, 2009). This oversight is unfortunate because the field of achievement motivation has many well-developed theories supported by a robust body of empirical research that could be relevant to the practice of school psychology. In fact, when it comes to predicting students’ performance, constructs related to achievement motivation are second only to intelligence (Kriegbaum et al., 2018). From this perspective, school psychologists may benefit from a clearer understanding of both the intra-individual components of achievement motivation and its contextual applications (Urdan & Schoenfelder, 2006). The five review articles in this special issue are designed to focus specifically on the integration of theories of achievement motivation to the practice of school psychology. Collectively, they meet the goal of providing school psychologists with an overview of five of the most common motivation frameworks tailored to school psychology in order to support student motivation at both the individual and contextual levels. The final commentary article explicates a whole-child framework to highlight the role motivation can hold alongside the recognizable school psychology constructs of cognition and affect.

description: In this paper we describe an adaptive and multi-scale algorithm for the parsimonious fit of the corneal surface data that allows to adapt the number of functions used in the reconstruction to the conditions of each cornea. The method implements also a dynamical selection of the parameters and the management of noise. It can be used for the real-time reconstruction of both altimetric data and corneal power maps from the data collected by keratoscopes, such as the Placido rings based topographers, decisive for an early detection of corneal diseases such as keratoconus. Numerical experiments show that the algorithm exhibits a steady exponential error decay, independently of the level of aberration of the cornea. The complexity of each anisotropic gaussian basis functions in the functional representation is the same, but their parameters vary to fit the current scale. This scale is determined only by the residual errors and not by the number of the iteration. Finally, the position and clustering of their centers, as well as the size of the shape parameters, provides an additional spatial information about the regions of higher irregularity. These results are compared with the standard approximation procedures based on the Zernike polynomials expansions.

description: Understanding the effect of manure particle fractionation on transport, retention, and
release of bacteria plays a critical role in manure management and environmental
policies that address soil and water bacterial pollution. Compared to soil particle
size, there is less understanding of the importance of solid manure particle size and
fractionation on bacterial fate and transport in soils. Four different cow manure particle
sizes (0.25, 0.5, 1, and 2 mm) were used to investigate Escherichia coli fate in a
saturated loamy sand soil. Leaching experiments were performed for up to 20 pore
volumes. Preferential transport of chloride mitigated as manure particle size increased.
The larger manure fractions (1 and 2 mm) showed greater heterogeneity in bacteria
transport and release; smaller manure fractions (0.25 and 0.5 mm) had a greater bacteria
retention with retarded release. Bacteria release was associated with transport and
re-entrainment of manure particles through soil columns. The results highlighted the
contribution of fine and transported particles as of primary importance for retention near
the surface and transporting bacteria in soil. Similar retention shapes (i.e., exponential)
for different fractions illustrated the similarity of manure source, where greater retention
was observed at 0−3 cm depth for the smallest (0.25 mm) and largest (2 mm) manure
fractions. The findings also highlighted the dependency of bacteria transport, retention,
and release on manure physical fractionation, which should be considered in managing
soil and manure practices in the field.
Deep sequencing of HIV-1 envelope determines coreceptor usage and predicts virologic responses to antiretroviral treatment with CCR5 antagonist medication
Creators: name: Swenson, Luke Christopher
Publisher: name: University of British Columbia
Year: 2014

description: Next-generation sequencing can be used to genotype an array of HIV variants within clinical specimens, in a process referred to as deep sequencing. When directed at the gene for HIV envelope, this approach can be used to generate a high-sensitivity overview of the viral tropism of the HIV quasispecies in an infected individual. Since HIV variants with tropism for the CXCR4 coreceptor are not susceptible to the CCR5 antagonist agent maraviroc, their detection is crucial in order to screen out patients unlikely to achieve viral load declines on maraviroc. There are several assays that test HIV tropism, but it has been unclear as to which are most useful in the clinical setting. The aim of this thesis is to compare next-generation sequencing using massively parallel pyrosequencing against several alternative tropism assays in a total of four large randomized clinical trials of maraviroc. The methodologies are refined and optimized in the early chapters and applied to clinical specimens from a total of 2864 HIV-infected individuals. The concordance of next-generation sequencing with phenotypic tropism assays reached 87%. Relative to both the original Trofile phenotypic assay and standard population-based sequencing, deep sequencing had higher sensitivity to detect minority non-R5 HIV. Where assays gave discordant results, deep sequencing tended to outperform the comparator assay and was able to better discriminate maraviroc responders from non-responders. Next-generation sequencing had excellent performance in populations of both treatment-experienced and treatment-naïve individuals. It was consistently able to determine coreceptor usage, and to predict which patients would respond to maraviroc. It could be performed using either HIV RNA from blood plasma or HIV DNA from peripheral blood mononuclear cells. Additionally, longitudinal deep sequencing was performed on samples taken prior to maraviroc administration and again at treatment failure. Phylogenetic analyses confirmed that the non-R5 variants present at time of maraviroc treatment failure were derived from variants detected by deep sequencing before treatment was initiated. In conclusion, next-generation sequencing was applied to thousands of samples from phase III clinical trials, and was a superior screening tool to those originally used during trial enrollment. This thesis demonstrates the clinical utility of next-generation sequencing.

Sivec & Zwick (1987) redescribed this species from the lectotype and indicated an unusually large range including China, Vietnam, Laos, Thailand and Myanmar. The subtle variations in aedeagal armature they note suggests this is a probable species complex which will require more material from throughout this range in order to gain resolution. Our sample shows little variation in aedeagal armature; the aedeagal tube is slender, sclerotized and bears minute spinules on the apical third. The sac has a prominent dorsobasal spiny cushion, a mid dorsal row of medium size spines and three irregular lateral rows of larger, cultriform spines imbedded proximal to a ventral grouping of fine spinules. Figs. 88‐90 show the first SEM images for the egg of this species.

description: Improved interoperability between public and private organizations is of key significance to make digital government newest triumphant. Digital Government interoperability, information sharing protocol and security are measured the key issue for achieving a refined stage of digital government. Flawless interoperability is essential to share the information between diverse and merely dispersed organisations in several network environments by using computer based tools. Digital government must ensure security for its information systems, including computers and networks for providing better service to the citizens. Governments around the world are increasingly revolving to information sharing and integration for solving problems in programs and policy areas. Evils of global worry such as syndrome discovery and manage, terror campaign, immigration and border control, prohibited drug trafficking, and more demand information sharing, harmonization and cooperation amid government agencies within a country and across national borders. A number of daunting challenges survive to the progress of an efficient information sharing protocol. A secure and trusted information-sharing protocol is required to enable users to interact and share information easily and perfectly across many diverse networks and databases globally.

description: Aims. We search for low-mass companions in the innermost region (<300 mas, i.e., 6 AU) of the beta Pic planetary system. Methods. We obtained interferometric closure phase measurements in the K-band with the VLTI/AMBER instrument used in its medium spectral resolution mode. Fringe stabilization was provided by the FINITO fringe tracker. Results. In a search region of between 2 and 60 mas in radius, our observations exclude at 3 sigma significance the presence of companions with K-band contrasts greater than 5e-3 for 90% of the possible positions in the search zone (i.e., 90% completeness). The median 1-sigma error bar in the contrast of potential companions within our search region is 1.2e-3. The best fit to our data set using a binary model is found for a faint companion located at about 14.4 mas from beta Pic, which has a contrast of 1.8e-3 \pm 1.1e-3 (a result consistent with the absence of companions). For angular separations larger than 60 mas, both time smearing and field-of-view limitations reduce the sensitivity. Conclusions. We can exclude the presence of brown dwarfs with masses higher than 29 Mjup (resp. 47 Mjup) at a 50% (resp. 90%) completeness level within the first few AUs around beta Pic. Interferometric closure phases offer a promising way to directly image low-mass companions in the close environment of nearby young stars.

description: The long-lived stau scenario is an interesting possibility at the LHC. We study squark mass measurements in this scenario; in particular, we show that left- and right-handed squark masses are both measurable. In SUSY events, multiple jets are expected, which become a source of combinatorial backgrounds. In order to reduce such backgrounds a hemisphere analysis is applied, and we discuss mass measurements of squarks in decay modes of left-handed squark into quark + (neutral / charged) Wino and also right-handed squark into quark + Bino.

description: We present the results of a search for unusually rapidly rotating giant stars in a large sample of K giants (~1300 stars) that had been spectroscopically monitored as potential targets for the Space Interferometry Mission's Astrometric Grid. The stars in this catalog are much fainter and typically more metal-poor than those of other catalogs of red giant star rotational velocities, but the spectra generally only have signal-to-noise (S/N) of ~20-60, making the measurement of the widths of individual lines difficult. To compensate for this, we have developed a cross-correlation method to derive rotational velocities in moderate S/N echelle spectra to efficiently probe this sample for rapid rotator candidates. We have discovered 28 new red giant rapid rotators as well as one extreme rapid rotator with a vsini of 86.4 km/s. Rapid rotators comprise 2.2% of our sample, which is consistent with other surveys of brighter, more metal-rich K giant stars. Although we find that the temperature distribution of rapid rotators is similar to that of the slow rotators, this may not be the case with the distributions of surface gravity and metallicity. The rapid rotators show a slight overabundance of low gravity stars and as a group are significantly more metal-poor than the slow rotators, which may indicate that the rotators are tidally-locked binaries.

Female. Unknown. Larva. Unknown. Etymology. The species name refers to the presumed rarity of this species. Diagnosis. This small, dark brown species has relatively straight, inwardly slanted hemitergal processes, few sensilla basiconica on tergum 8 and none on tergum 9; however a few long setae are present in a mesal patch on tergum 9 between the tips of the hemitergal processes. The aedeagal sac is extraordinarily long, at least 2.5 times as long as the tube and the sac armature consists of an irregular, sparse row of large spines along most of the sac length. The tube bears two pairs of small, ventrolateral spiny knobs beyond midlength. The aedeagus of this species does not appear very similar to any of the known Asian species. The size and color pattern of this species are similar to N. teresa and Neoperla VN‐ A (both described below) but N. monacha differs from both in having uniformly dark hind femora.

description: Brown dwarfs are intermediate objects between planets and stars. The lower end of the brown-dwarf mass range overlaps with the one of massive planets and therefore the distinction between planets and brown-dwarf companions may require to trace the individual formation process. We present results on new potential brown-dwarf companions of Sun-like stars, which were discovered using CORALIE radial-velocity measurements. By combining the spectroscopic orbits and Hipparcos astrometric measurements, we have determined the orbit inclinations and therefore the companion masses for many of these systems. This has revealed a mass range between 25 and 45 Jupiter masses almost void of objects, suggesting a possible dividing line between massive planets and sub-stellar companions.

The effect of patient-, implant design-, bone graft-, implant placement timing-, and intrasurgical-related risk factors on implant survival, marginal bone loss, sinus membrane tears, major postoperative complications, and operating time were evaluated. Preoperative Cone Beam Computed Tomography (CBCT) images were evaluated using Kodak 3D Imaging v2.4 software and the distribution of interfering septa according to Class I (buccal-lingual direction), Class II (mesial- distal direction), Class III (horizontal orientation), and Class IV (combinations of Class I, II, or III) was assessed. Radiographic measurements of marginal bone loss (mm) were made using Image J v1.46 software. Results: Interfering septa were identified in 48.1% of sinuses. Of sinuses with septa, 71.1% of these contained a Class I septum. The overall implant survival rate was 100%. Patient-related risk factors were not found to be significantly associated with marginal bone loss, the occurrence of sinus membrane tears, or any major postoperative complications. Non-platform-shifted implants were found to be significantly associated with increased marginal bone loss (P<0.001). Sinus membrane tears were not found to be associated with either major postoperative complications or increased marginal bone loss. The presence of a septum on the pre-operative CBCT scan was found to be significantly associated with the occurrence of a sinus membrane tear (P<0.001). ii Conclusions: The identification of interfering septa on preoperative CBCT scans was associated with the occurrence of intrasurgical sinus membrane tears, however the occurrence of tears was not associated with major postoperative complications or implant marginal bone loss.

We show that the same gaugino condensate which is introduced to stabilize the dilaton breaks supersymmetry. We study the constraints on the scale of supersymmetry breaking which this mechanism leads to.

description: Hysteretic giant magnetoimpedance (GMI) of amorphous ribbons with a well-defined transversal domain structure is investigated by means of first-order reversal curves (FORC) analysis. The FORCs are not confined to the hysteretic area, exceeding the major curve amplitude. Irreversible switches of the transverse permeability, caused by domain wall structure transitions, may be the origin of the observed FORC distribution. An interlinked hysteron/anti-hysteron model is proposed to interpret it, which allows analyzing the influence of frequency and magnetostriction upon the hysteretic GMI effect.

description: We present spherically symmetric boson stars as black hole mimickers based on the power spectrum of a simple accretion disk model. The free parameters of the boson star are the mass of the boson and the fourth order self-interaction coefficient in the scalar field potential. We show that even if the mass of the boson is the only free parameter it is possible to find a configuration that mimics the power spectrum of the disk due to a black hole of the same mass. We also show that for each value of the self-interaction a single boson star configuration can mimic a black hole at very different astrophysical scales in terms of the mass of the object and the accretion rate. In order to show that it is possible to distinguish one of our mimickers from a black hole we also study the deflection of light.

On non-abelian T-dual geometries with Ramond fluxes

description: We show how to implement T-duality along non-abelian isometries in backgrounds with non-vanishing Ramond fields. When the dimension of the isometry group is odd (even) the duality swaps (preserves) the chirality of the theory. In certain cases a non-abelian duality can result in a massive type-IIA background. We provide two examples by dualising SU(2) isometry subgroups in $AdS_5\times S^5$ and $AdS_3\times S^3\times T^4$. The resultant dual geometries inherit the original AdS factors but have transverse spaces with reduced isometry and preserve only half of the original supersymmetry. The non-abelian dual of $AdS_5\times S^5$ has an M-theory lift which is related to the gravity duals of N=2 superconformal theories. We comment on a possible interpretation of this as a high spin limit.

Exact Free Distance and Trapping Set Growth Rates for LDPC Convolutional Codes

description: Ensembles of (J,K)-regular low-density parity-check convolutional (LDPCC) codes are known to be asymptotically good, in the sense that the minimum free distance grows linearly with the constraint length. In this paper, we use a protograph-based analysis of terminated LDPCC codes to obtain an upper bound on the free distance growth rate of ensembles of periodically time-varying LDPCC codes. This bound is compared to a lower bound and evaluated numerically. It is found that, for a sufficiently large period, the bounds coincide. This approach is then extended to obtain bounds on the trapping set numbers, which define the size of the smallest, non-empty trapping sets, for these asymptotically good, periodically time-varying LDPCC code ensembles.

description: Neoperla erecta sp. n. (Figs. 23‐25) Material examined. Holotype ♂ from Vietnam, Lao Cai, Muong Hoa Ho River, 5‐12 May 1995, D. Currie, B. Hubley, J. Swann, ROM 956007 (ROM). Adult habitus. Biocellate. Head pale except for quadrate spot over ocelli and obscure chevron centered on anterior of frons (Fig. 23). Wing membrane, veins and legs pale. Male. Forewing length 9.5 mm. Process of tergum 7 small, rounded and margined with spines. Mesal field of tergum 8 bearing a sparse patch of sensilla basiconica; mesal field of tergum 9 bearing long setae and mixed sensilla basiconica (Fig. 24). Hemitergal lobes broad basolaterally and narrow at apex; hemitergal processes long, slender and curved near midlength. Aedeagal tube plump and weakly sclerotized; aedeagal sac longer than tube, erect, strongly directed ventrad, and originating in a preapical position (Fig. 25). Sac armed over most of surface with small triangular spines; spines larger on lateral humps at midlength and in patch near apex. Female. Unknown. Larva. Unknown. Etymology. The species name refers to the upright (but ventrally directed) orientation of the aedeagal sac. Diagnosis. The aedeagus of N. erecta is similar to that of N. melanocephala (Navás), a species from Myanmar redescribed by Zwick (1988). That species, however, is very dark and the aedeagal sac is covered rather completely by small spines of uniform size except for slightly larger ones in a partial basal ring. Among known Vietnamese species the aedeagus is generally similar to that of N. nebulosa but these species are fundamentally different in the pattern and shape of male tergal lobes in addition to conspicuous differences in aedeagal sac armature.

Vietnam: Gia Lai, An Khe District, Tram Lap, 2 km NW on trail from forestry building, 14 ° 27’ N, 108 ° 33’ E, 17 June 1996, D. Currie, J. Swann, ROM 961056, 1 ♂ (ROM). Remarks. This species was previously reported from Java, Sumatra, Malaysia and Thailand where considerable variation in egg collar morphology was noted (Zwick 1983). This Vietnamese specimen appears to have a more prominent dorsobasal spine patch on the aedeagal sac, and the subapical spines also appear more prominent than shown for Malaysian specimens (Zwick 1983). In addition the membranous lateral areas of much of the tube are covered with fine spinules in this specimen but these are not mentioned by Zwick (1983).

description: The problem of infrared divergence of the effective electromagnetic field produced by elementary particles is revisited using the non-equilibrium model of an electron interacting with low-temperature photons. It is argued that the infrared singularity of the effective field can be interpreted as a thermalization of the electron. It is shown that this thermalization is negligible in actual field measurements as it is completely dominated by the usual quantum spreading.

description: Vocabularies are used in a wide range of services. These include long-term digital archives as well as research project overview websites and training platforms. Vocabularies allow depositors and users to describe resources by indicating their most relevant aspects, usually summarised in single keywords. Analysing vocabularies is therefore a productive way of discovering which aspects of a research area are covered by a particular service, and how services relate to each other. This hands-on session presents a practical workflow for comparing vocabularies from different services and identifying possible overlaps. “Vocabularies” is used here in a broad sense, including both controlled vocabularies (ranging from controlled lists to thesauri) and folksonomies, i.e. collections of uncontrolled keywords used in a service. A Jupyter notebook is included, containing the Python code needed to perform the comparison. A set of vocabularies are already provided for comparison (such as the SSH Open Marketplace keywords and Getty AAT). In addition, an accompanying presentation illustrates some preliminary thoughts on vocabulary terminology, usage and interoperability (with a special focus on the users’ perspective) as well as the description of a comparison between vocabularies of the Austrian DH community recently performed at the Austrian Centre for Digital Humanities and Cultural Heritage.
