description: Practical applications of graphene require a reliable high-throughput method of graphene identification and quality control, which can be used for large-scale substrates and wafers. We have proposed and experimentally tested a fast and fully automated approach for determining the number of atomic planes in graphene samples. The procedure allows for in situ identification of the borders of the regions with the same number of atomic planes. It is based on an original image processing algorithm, which utilizes micro-Raman calibration, light background subtraction, lighting non-uniformity correction, and the color and grayscale image processing for each pixel. The outcome of the developed procedure is a pseudo-color map, which marks the single-layer and few-layer graphene regions on the substrate of any size that can be captured by an optical microscope. Our approach works for various substrates, and can be applied to the mechanically exfoliated, chemically derived, deposited or epitaxial graphene on an industrial scale.

title: A Qualitative Investigation of the Life Stories of Sixteen Saudi Arabian People who Stutter (PWS)
Creators: name: Bukhari, Reham Shaker Yldash
Publisher: name: University of Reading
Year: 2023

description: Stuttering is a speech impediment that some people have to deal with in their everyday life. Recently, greater focus has been given to the influence of stuttering on the quality of life of individuals with stuttering. However, the lived experience of stuttering as understood by people who stutter (PWS) has not been subjected to much qualitative inquiry; this would enable stuttering’s effect on PWS’ lives—or lack of effect—and the impediment’s meaning to them to be understood. The focus of this study is to explore the lived experience among Saudi Arabian PWS, resolving shortcomings in the extant research through listening to the voices of PWS. The study is framed using the Social Relational Model of Disability (SRMD) as the lens for interpreting data. The method of data collection and analysis was the life story approach. 16 Saudi Arabian PWS between the ages of 18 and 57—eight women and eight men—participated in the life story interview process. The lived experiences of stuttering from the perspective of people who stutter involved stories related to stuttering in educational, professional and social contexts, with educator and parental assistance influencing the way they perceived their experience. The participants reconstructed their life stories by adopting different types of narrative, including narratives of difficulties, acceptance and multiple selves. PWS’ lived experience may be impeded due to their interaction with social obstacles, insufficient assistance and negative stereotyping in the education system, work, and domestic environments. Implications of this for how society might more positively embrace PWS are discussed.

Hierarchical reinforcement learning with multi-step actions
Creators: name: Schoknecht, Ralf
Publisher: name: Karlsruhe
Year: 2001

description: In recent years hierarchical concepts of temporal abstraction
have been integrated in the reinforcement learning framework to
improve scalability. However, existing approaches are limited to
domains for which a decomposition in subtasks is known a priori.
In this paper we propose the concept of multi-step actions on
different time scales in one single action set. It is suited for
learning optimal policies in unstructured domains where a
decomposition is not known in advance or does not exist at all.
At the same time this approach enables learning at multiple
levels of temporal abstraction. Thus, multi-step actions offer
the possibility to obtain faster learning algorithms for
unstructured domains.

description: A lot of online marketing campaigns aim to promote user interaction. The average treatment effect (ATE) of campaign strategies need to be monitored throughout the campaign. A/B testing is usually conducted for such needs, whereas the existence of user interaction can introduce interference to normal A/B testing. With the help of link prediction, we design a network A/B testing method LinkLouvain to minimize graph interference and it gives an accurate and sound estimate of the campaign's ATE. In this paper, we analyze the network A/B testing problem under a real-world online marketing campaign, describe our proposed LinkLouvain method, and evaluate it on real-world data. Our method achieves significant performance compared with others and is deployed in the online marketing campaign.

description: Markov chain Monte Carlo (MCMC) is a powerful methodology for the approximation of posterior distributions. However, the iterative nature of MCMC does not naturally facilitate its use with modern highly parallel computation on HPC and cloud environments. Another concern is the identification of the bias and Monte Carlo error of produced averages. The above have prompted the recent development of fully ('embarrassingly') parallel unbiased Monte Carlo methodology based on coupling of MCMC algorithms. A caveat is that formulation of effective coupling is typically not trivial and requires model-specific technical effort. We propose coupling of MCMC chains deriving from sequential Monte Carlo (SMC) by considering adaptive SMC methods in combination with recent advances in unbiased estimation for state-space models. Coupling is then achieved at the SMC level and is, in principle, not problem-specific. The resulting methodology enjoys desirable theoretical properties. A central motivation is to extend unbiased MCMC to more challenging targets compared to the ones typically considered in the relevant literature. We illustrate the effectiveness of the algorithm via application to two complex statistical models: (i) horseshoe regression; (ii) Gaussian graphical models.

description: A general framework for solving nonlinear least squares problems without the employment of derivatives is proposed in the present paper together with a new general global convergence theory. With the aim to cope with the case in which the number of variables is big (for the standards of derivative-free optimization), two dimension-reduction procedures are introduced. One of them is based on iterative subspace minimization and the other one is based on spline interpolation with variable nodes. Each iteration based on those procedures is followed by an acceleration step inspired in the Sequential Secant Method. The practical motivation for this work is the estimation of parameters in Hydraulic models applied to dam breaking problems. Numerical examples of the application of the new method to those problems are given.

Householder orthogonalization with a non-standard inner product

description: Householder orthogonalization plays an important role in numerical linear algebra. It attains perfect orthogonality regardless of the conditioning of the input. However, in the context of a non-standard inner product, it becomes difficult to apply Householder orthogonalization due to the lack of an initial orthonormal basis. We propose strategies to overcome this obstacle and discuss algorithms and variants of Householder orthogonalization with a non-standard inner product. Theoretical analysis and numerical experiments demonstrate that our approach is numerically stable under mild assumptions.

Herleitung verbesserter hierarchischer Plattenmodelle und deren Integralgleichungsformulierung [online]
Creators: name: Westphal, Tancredo

description: Abstract

The objective of this dissertation is the derivation of a
hierarchical formulation for the differential and integral
equations of a twelfth-order plate bending model for homogeneous
transversely isotropic materials, named after Poniatovskii and
Reissner. The hierachical characteristic means that the direct
reduction from the twelfth-order equation system automatically
leads to corresponding systems of lower-order. By the first
simplification we obtain the sixth-order equation system of
Reissner (and Mindlin) and, by taking the limit of the thickness
to zero or the shear stiffness to infinity, the fourth-order
Kirchhoff bending equation. The simplification from the
twelfth-order to the sixth-order system is performed by the
selection of particular values for the two coupling variables.
The differential equations of the twelfth-order model are
obtained by application of the Hellinger-Reissner mixed
variational principle. For the dimensional reduction we propose
as starting point an expansion of the displacements along the
plate thickness in the form of Legendre polynomials. In the
sequel we determine the corresponding stress field in order to
evaluate the expression for the complementary energy density to
be used in the variational principle.
The weighted residual method leads to the corresponding system
of hierarchical integral equations allowing for the simultaneous
BEM formulation of both, the sixth-order and the twelfth-order
plate models. It is shown that the system of differential
equations gives a better approximation of the three-dimensional
elasticity equations than displacement-based models. The
hierarchical reduction of the twelfth-order integral equations
yields the known sixth-order equations of van der Weeen, now for
transversely isotropic materials.

description: Synoptic spectroscopic observations of the U Sco 2010 outburst from maximum light to quiescence as well as a contemporaneous X-ray observation are presented and analyzed. The X-ray spectrum 52 days after outburst indicates a hot source (kTbb ~ 70 eV). . Narrow line components from the irradiated companion atmosphere were observed in hydrogen and helium optical recombination lines. The formation of a nebular spectrum is seen for the first time in this class of recurrent novae, allowing a detailed study of the ejecta using photoionization models. Unusual [OIII] auroral-to-nebular line ratios were found and possible scenarios of their origin are discussed. The modeling of the emission line spectrum suggests a highly heterogeneous ejecta with mass around or above 3 x 10-6 Msun

description: We propose here a high-frequency spin-Hall nano-oscillator based on a simple magnetic texture, such as a domain wall, located in an antiferromagnet with easy-axis anisotropy type. We show that the spin current, polarized along the anisotropy axis, excites a conical precession of the Néel vector in such a domain wall, which allows obtaining a robust ac output signal, -- contrary to the planar precession in an uniform uniaxial antiferromagnet, where ac output is hard to achieve. The frequency of the auto-oscillations is easily tunable by the applied current up to the THz range, and the threshold current vanishes for pure uniaxial antiferromagnet. By micro-magnetic simulations, we demonstrate that the pinning of the domain wall is crucial for the oscillator design, which can be achieved in nano-constriction layout of the free layer.

description: During 2010 the LHC delivered pp collisions with a centre-of-mass energy of 7 TeV. In this paper, the results of comprehensive studies of missing transverse energy as measured by the CMS detector are presented. The results cover the measurements of the scale and resolution for missing transverse energy, and the effects of multiple pp interactions within the same bunch crossings on the scale and resolution. Anomalous measurements of missing transverse energy are studied, and algorithms for their identification are described. The performances of several reconstruction algorithms for calculating missing transverse energy are compared. An algorithm, called missing-transverse-energy significance, which estimates the compatibility of the reconstructed missing transverse energy with zero, is described, and its performance is demonstrated.

Foraging niche structure and coexistence in a highly diverse community of Amazonian antbirds (Thamnophilidae: Aves)
Creators: name: David, Santiago
Publisher: name: University of British Columbia
Year: 2016

description: The high species richness of antbirds (Thamnophilidae) in Amazonian lowlands, where as many as 40 species may coexist at local scales, represents a major challenge for ecologists to explain patterns of coexistence and niche evolution. I studied the foraging ecology of a local community of antbirds in a 2-Km² area of lowland forest in SE Peru to examine how co-occurring antbird species differ in their use of foraging resources, and whether these differences result in niche partitioning at the community level. I also examined whether resource use similarity was related to phylogenetic similarity in this local assemblage. Forty-four species of antbirds were detected in the study plot in a four-year period, with 30 species categorized as the local assemblage of common resident breeders. Multivariate analysis of foraging parameters showed that segregation at two height layers in two types of forest was more important than foraging substrates and maneuvers in explaining the differences observed in foraging behavior. However, a null model analysis revealed that at the community level, antbirds exhibited high foraging niche overlap, with average observed overlap significantly larger than expected by chance, indicating that antbirds prefer, rather than avoid, resources used by other species. No general relationship exists between phylogenetic similarity and niche overlap. Closely related species consistently exhibit high values of niche overlap, but some distantly related species also exhibit high niche similarity. Taken together, these results suggest that foraging niche similarity is the predominant pattern among co-occurring antbirds, and that positive interactions might explain the stable coexistence of species that use similar resources and habitats at a local scale.

description: Image quality assessment (IQA) is very important for both end-users and service providers since a high-quality image can significantly improve the user's quality of experience (QoE) and also benefit lots of computer vision algorithms. Most existing blind image quality assessment (BIQA) models were developed for synthetically distorted images, however, they perform poorly on in-the-wild images, which are widely existed in various practical applications. In this paper, we propose a novel BIQA model for in-the-wild images by addressing two critical problems in this field: how to learn better quality-aware feature representation, and how to solve the problem of insufficient training samples in terms of their content and distortion diversity. Considering that perceptual visual quality is affected by both low-level visual features (e.g. distortions) and high-level semantic information (e.g. content), we first propose a staircase structure to hierarchically integrate the features from intermediate layers into the final feature representation, which enables the model to make full use of visual information from low-level to high-level. Then an iterative mixed database training (IMDT) strategy is proposed to train the BIQA model on multiple databases simultaneously, so the model can benefit from the increase in both training samples and image content and distortion diversity and can learn a more general feature representation. Experimental results show that the proposed model outperforms other state-of-the-art BIQA models on six in-the-wild IQA databases by a large margin. Moreover, the proposed model shows an excellent performance in the cross-database evaluation experiments, which further demonstrates that the learned feature representation is robust to images with diverse distortions and content. The code is available at https://github.com/sunwei925/StairIQA.

title: Structural sequence and petrogenesis of the polyphase deformed Precambrian terrane of the Vila Nova region, State of Rio Grande do Sul, Southern Brazil
Creators: name: Filho, Breno Correa da Silva
Publisher: name: University of Glasgow
Year: 1984
Subjects: subject: Earth sciences, Brazil, structural geology.

description: Evidence is presented concerning the nature and development of the structural pattern existing in the region of Vila Nova, State of Rio Grande do Sul, Southern Brazil. A supracrustal rock assemblage made up predominantly of quartzofeldspathic gneisses, ranging in composition from dioritic to granodioritic; migmatites, and associated layers and lenses of amphibolite, have undergone an extensive polyphase deformational and metamorphic history, within which multiple igneous injections played a prominent role. This mixed rock assemblage which is here designated "Vila Nova Complex" forms part of the Precambrian rocks of the Sulriograndence Shield. Despite the high degree of structural complexity it has been possible to establish a deformational sequence mainly on the basis of refolding and cross-cutting relationships seen in the field. Correlation between different areas of outcrop has been carried out on the basis of eleven phases of deformation that have been recognized, and their relationships with various intrusive masses. A gneissose foliation, formed during the first deformational phase (D1), and folds of varying style and size and related igneous intrusions, developed during the third deformational phase (D3), are key elements in the elucidation of the geological development of the rock complex. The dominant foliation (S1) which generally parallels the original layering (S0) is commonly associated with and axial-planar to isoclinal, intrafolial, rootless folds (F1). The main phases of igneous activity took place during both late and with the emplacement of structurally-controlled tonalitic to trondhjemitic and granodioritic masses, respectively. The complex fold patterns displayed by various neosomes are the result of polyphase deformation rather than ptygmatic activity. On the basis of different structural features representing a long-lasting progressive deformation three markedly distinct general compressive stress-systems have been distinguished in the course of the orogeny which caused the formation of the Vila Nova Complex. This orogeny appears to have occurred along convergent plate boundaries involving a continent-continent collision model.

description: Highly energetic magnetic fluctuations, discovered in high-temperature superconductors (HTSC) by inelastic neutron scattering (INS), are now widely believed to be vital for the superconductivity. In two competing scenarios, they either originate from local atomic spins, or are a property of cooperative spin-density-wave (SDW) behavior of conduction electrons. Both assume clear partition into localized electrons, giving rise to local spins, and itinerant ones, occupying well-defined, rigid conduction bands. Here, by performing an INS study of spin dynamics in iron telluride, a parent material of one of the iron-based HTSC families, we have discovered that this very assumption fails, and that conduction and localized electrons are fundamentally entangled. We find that the real-space structure of magnetic correlations can be explained by a simple local-spin plaquette model. However, the effective spin implicated in such a model, appears to increase with the increasing temperature. Thus, we observe a remarkable redistribution of magnetism between the two groups of electrons, which occurs in the temperature range relevant for the superconductivity. The analysis of magnetic spectral weight shows that the effective spin per Fe at T \approx 10 K, in the antiferromagnetic phase, corresponds to S \approx 1, consistent with the recent analyses that emphasize importance of Hund's intra-atomic exchange. However, it grows to S \approx 3/2 in the disordered phase, a result that profoundly challenges the picture of rigid bands, broadly accepted for HTSC.

description: The problem of covering a region of the plane with a fixed number of minimum-radius identical balls is studied in the present work. An explicit construction of bi-Lipschitz mappings is provided to model small perturbations of the union of balls. This allows us to obtain analytical expressions for first- and second-order derivatives using nonsmooth shape optimization techniques under appropriate regularity assumptions. Singular cases are also studied using asymptotic analysis. For the case of regions given by the union of disjoint convex polygons, algorithms based on Voronoi diagrams that do not rely on approximations are given to compute the derivatives. Extensive numerical experiments illustrate the capabilities and limitations of the introduced approach.

Evaluation of seismic performance of a pre-cast concrete block arch system through testing and numerical modeling

description: Lock-Block Ltd. from Vancouver, Canada, has developed an arch structural system made from modular pre-cast concrete blocks. The intention of the arch is to provide an easy to construct, cost effective and long lasting structure. This could be achieved with a modular, steel-free system. This study aims to assess the seismic performance of these arches characterizing their seismic behavior using a combination of experimental testing and numerical modeling. Several small scale unreinforced and reinforced arch models were subjected to quasi-static and dynamic testing. For the dynamic testing, a suite of earthquake records was selected of varying magnitudes, types and locations, and applied on a shake-table. From the results of the shake-table testing on the unreinforced models it was found that the arches tend to collapse by the four-hinge mechanism which is typical for these types of structures. For the reinforced arch testing, a steel band was instrumented to provide information on the loads. The reinforced arch performed well when subjected to the same suite of earthquakes. A numerical distinct element model was developed using 3DEC software and calibrated to the quasi-static test. The response of the numerical model matched the experiments with the arch exhibiting the same four-hinge failure mechanism. From numerical analysis, sensitivity studies were performed on various parameters of the arch. This included geometry, material properties and boundary/interface conditions. It was found that in this configuration, the arches are vulnerable to seismic excitation and at risk of collapse when unreinforced and unconfined. There are several solutions to reduce that risk based on the results of this work: 1) addition of external or internal reinforcement to prevent hinge opening 2) restraint of the bottom courses of blocks and 3) modification of the geometry at the base to improve stability.

description: When an iterative method is applied to solve the linear equation system in interior point methods (IPMs), the attention is usually placed on accelerating their convergence by designing appropriate preconditioners, but the linear solver is applied as a black box with a standard termination criterion which asks for a sufficient reduction of the residual in the linear system. Such an approach often leads to an unnecessary 'oversolving' of linear equations. In this paper, an IPM that relies on an inner termination criterion not based on the residual of the linear system is introduced and analyzed. Moreover, new indicators for the early termination of the inner iterations are derived from a deep understanding of IPM needs. The new technique has been adapted to the Conjugate Gradient (CG) and to the Minimum Residual method (MINRES) applied in the IPM context. The new criterion has been tested on a set of quadratic optimization problems including compressed sensing, image processing and instances with partial differential equation constraints, and it has been compared to standard residual tests with variable tolerance. Evidence gathered from these computational experiments shows that the new technique delivers significant improvements in terms of inner (linear) iterations and those translate into significant savings of the IPM solution time.

description: Stress annealing is utilized for enhancing the magnetic softness of Fe83–xCoxB10Si3C3P1 (x = 0–16) amorphous alloys with saturation polarization up to 1.75 T. All of the stress-annealed alloys exhibit improved soft-magnetic properties, including low coercivity of 1.8–2.2 A/m, low core loss of 0.09–0.11 W/kg at 1.0 T and 50 Hz, and high permeability of 27,000–33,200 at 5 A/m and 1 kHz. Stress annealing induces longitudinal magnetic anisotropy and facilitates the annihilation of free volume, leading to pinning-free domain wall motion, and thus the enhanced magnetic softness. The induced magnetic anisotropy relates to the constrained elastic elongation introduced by stress annealing. The stress-annealed Fe83–xCoxB10Si3C3P1 (x = 0–16) amorphous alloys exhibit excellent magnetic softness, sheding light on the designing and processing of amorphous soft magnetic alloys with high saturation polarization.

description: We present high accuracy relativistic coupled cluster calculations of the first and second ionisation potentials and the electron affinity of the heaviest element in the Periodic Table, Og. The results were extrapolated to the basis set limit and augmented with the higher order excitations (up to perturbative quadruples), the Breit contribution, and the QED self energy and vacuum polarisation corrections. We have performed an extensive investigation of the effect of the various computational parameters on the calculated properties, which allowed us to assign realistic uncertainties on our predictions. Similar study on the lighter homologue of Og, Rn, yields excellent agreement with experiment for the first ionisation potential and a reliable prediction for the second ionisation potential.

MIPSGAL 24 μm Observations of Galactic Planetary Nebulae

description: We have obtained 24 μm imaging, profiles and fluxes for 224 planetary nebulae (PNe) lying within the limits of the Spitzer MIPSGAL survey. It is noted that most of the PNe having extended 24 μm emission also possess circular morphologies, suggesting that the emission derives from cool grains located within the AGB mass-loss regimes. Certain of these halos are found to have a surface brightness fall-off which may be consistent with secularly invariant mass-loss within the PNe progenitors. By contrast, the 8.0 μm envelopes are detected out to smaller distances from the nuclei, and have a steeper rate of surface brightness fall-off; a phenomenon which may arise from changes in the excitation of polycyclic aromatic hydrocarbons (PAHs) within external photo-dissociation regimes (PDRs). Our 24μm fluxes are compared to those in previously published studies, and this appears to indicate that many of the prior fluxes have been underestimated; a disparity may imply that previous aperture sizes were too small. We have also combined our 24 μm fluxes with measures at shorter mid-infrared (MIR) wavelengths, taken with the Infrared Array Camera (IRAC). These are used to investigate the positioning of PNe within the IRAC-MIPSGAL colour planes. The [8.0]-[24] and [5.8]-[24] colours are found to be large, and extend over the respective ranges 3.4-8.7 mag, and 5.4-10.3 mag; indices which are only explainable where a broad range of mechanisms contribute to the fluxes, including PAH bands, cool dust continua, and a variety of ionic transitions. These and other components also affect the morphologies of the sources, and lead to wavelength dependent changes in the widths of the profiles.

description: We investigate the thermoelectric properties of electrons at the interface of oxide heterostructure and in the presence of a multiferroic oxide with spiral spin order. We find there is no (spin) Hall current generated by the temperature gradient. A Seebeck effect is however present. Due to the magnetoelectric coupling, the charge and thermal conductivities are electrically controllable via the spin spiral helicity. Moreover, the thermopower exhibits a sign change when tuning electro-statically the carrier density.
