description: The penetration of magnetic flux fronts in the optimally-doped iron-based superconductor Ba(Fe$_{1-x}$Co$_{x}$)$_{2}$As$_2$ ($x = 0.07 \pm 0.005$) is studied by means of magneto-optical imaging and Bitter decoration. The higher-order analysis of roughening and growth of the magnetic flux front reveals anomalous scaling properties, indicative of non-Gaussian correlations of the disorder potential. While higher-order spatial correlation functions reveal multi-fractal behavior for the roughening, the usual Kardar-Parisi-Zhang growth exponent is found. Both exponents are found to be independent of temperature. The scaling behavior is manifestly different from that found for other modes of flux penetration, such as that mediated by avalanches, suggesting that multi-scaling is a powerful tool for the characterization of roughened interfaces. We propose a scenario for vortex penetration based on two-dimensional percolation and cluster aggregation for an inhomogeneously disordered superconductor.

description: In this study, the structural and basic astrophysical parameters of the poorly studied open cluster Berkeley 6 are calculated. Analyses of the cluster are carried out using the third photometric, spectroscopic, and astrometric data release of Gaia (Gaia DR3). The membership probabilities of stars located in the direction of the cluster region are calculated by considering their astrometric data. Thus, we identified 119 physical members for Berkeley 6. The colour excess, distance, and age of the cluster are determined simultaneously on the colour-magnitude diagram. We fitted solar metallicity PARSEC isochrones to the colour-magnitude diagram by considering the most probable member stars and obtained $E(G_{\rm BP}-G_{\rm RP})$ colour excess as 0.918$\pm$0.145 mag. The distance and age of the cluster are determined as $d=2625\pm337$ pc and $t=350\pm50$ Myr, respectively.

description: This work considers a computationally and statistically efficient parameter estimation method for a wide class of latent variable models---including Gaussian mixture models, hidden Markov models, and latent Dirichlet allocation---which exploits a certain tensor structure in their low-order observable moments (typically, of second- and third-order). Specifically, parameter estimation is reduced to the problem of extracting a certain (orthogonal) decomposition of a symmetric tensor derived from the moments; this decomposition can be viewed as a natural generalization of the singular value decomposition for matrices. Although tensor decompositions are generally intractable to compute, the decomposition of these specially structured tensors can be efficiently obtained by a variety of approaches, including power iterations and maximization approaches (similar to the case of matrices). A detailed analysis of a robust tensor power method is provided, establishing an analogue of Wedin's perturbation theorem for the singular vectors of matrices. This implies a robust and computationally tractable estimation approach for several popular latent variable models.

description: Evidence is given for the effectiveness of InAs surface passivation by the growth of an epitaxial InAlAs shell. The electron mobility is measured as a function of temperature for both core-shell and unpassivated nanowires, with the core-shell nanowires showing a monotonic increase in mobility as temperature is lowered, in contrast to a turnover in mobility seen for the unpassivated nanowires. We argue that this signifies a reduction in low temperature ionized impurity scattering for the passivated nanowires, implying a reduction in surface states.

Lecture notes on Statistical methods in business
Creators: name: Gürsoy, Kemal
Publisher: name: No Publisher Supplied
Year: 2020

description: These notes correspond to my one semester long lectures that I give at the Rutgers Business School, Newark and New Brunswick campuses, New Jersey. I focus on representing the statistical methods, used by the business world, at a level of the third-year undergraduate curriculum. This course has a prerequisite requirement, at the level of an introduction to statistics and probability theory course offered by an undergraduate university curriculum. Hence, we employ statistical methods in these lectures and use them to approach to practical business problems.There are multiple sections of this course, thus we use a common textbook to provide a reference frame for our lectures. My notes supplement and add explanations to the textbook information, to some degree. Thus, these notes are not a substitute of the textbook, but an enrichment of the students’ learning, as an additional source of knowledge, during my lectures.I believe that any student who is studying the textbook and attending lectures, will benefit having these lecture notes as exposure of my understanding on this subject.I enjoy giving my lectures since most of my students engage my lectures in the classroom and show interest in the subject outside of the classroom. That motivates me immensely to provide good lectures to my students, and I want to thank my students for this.

description: While adaptive sensing has provided improved rates of convergence in sparse regression and classification, results in nonparametric regression have so far been restricted to quite specific classes of functions. In this paper, we describe an adaptive-sensing algorithm which is applicable to general nonparametric-regression problems. The algorithm is spatially adaptive, and achieves improved rates of convergence over spatially inhomogeneous functions. Over standard function classes, it likewise retains the spatial adaptivity properties of a uniform design.

description: We present a maximum probability approach to reconstructing spatial maps of the peculiar velocity field at redshifts $z\sim0.1$, where the velocities have been measured from distance indicators (DI) such as $D_n-σ$ relations or Tully-Fisher. With the large statistical uncertainties associated with DIs, our reconstruction method aims to recover the underlying true peculiar velocity field by reducing these errors with the use of two physically motivated filtering prior terms. The first constructs an estimate of the velocity field derived from the galaxy over-density {\deltag} and the second makes use of the matter linear density power spectrum {\pk}. Using $N$-body simulations we find, with an SDSS-like sample ($N_{gal}\simeq33$ per deg$^2$), an average correlation coefficient value of $r=0.55\pm{0.02}$ between our reconstructed velocity field and that of the true velocity field from the simulation. However, with a suitably high number density of galaxies from the next generation surveys (e.g. $N_{gal}\simeq140$ per deg$^2$) we can achieve an average $r=0.70\pm{0.02}$ out to moderate redshifts $z\sim0.1$. This will prove useful for future tests of gravity, as these relatively deep maps are complementary to weak lensing maps at the same redshift.

description: This paper proposes the design of Fractional Order (FO) Butterworth filter in complex w-plane (w=sq; q being any real number) considering the presence of under-damped, hyper-damped, ultra-damped poles. This is the first attempt to design such fractional Butterworth filters in complex w-plane instead of complex s-plane, as conventionally done for integer order filters. Firstly, the concept of fractional derivatives and w-plane stability of linear fractional order systems are discussed. Detailed mathematical formulation for the design of fractional Butterworth-like filter (FBWF) in w-plane is then presented. Simulation examples are given along with a practical example to design the FO Butterworth filter with given specifications in frequency domain to show the practicability of the proposed formulation.

description: We present a new infinite class of near-horizon geometries of degenerate horizons, satisfying Einstein's equations for all odd dimensions greater than five. The symmetry and topology of these solutions is compatible with those of black holes. The simplest examples give horizons of spatial topology S^3xS^2 or the non-trivial S^3-bundle over S^2. More generally, the horizons are Lens space bundles associated to certain principal torus-bundles over Fano Kaehler-Einstein manifolds. We also consider the classification problem for Einstein metrics on such Lens space bundles and derive a family which unifies all the known examples (Sasakian and non-Sasakian).

description: We present a new method to detect Fermi surface instabilities for interacting systems at finite temperature. We first apply it to a list of cases studied previously, recovering already known results in a very economic way, and obtaining most of the information on the phase diagram analytically. As an example, in the continuum limit we obtain the critical temperature as an implicit function of the magnetic field and the chemical potential $T_c(μ,h)$. By applying the method to a model proposed to describe reentrant behavior in $Sr_3Ru_2O_7$, we reproduce the phase diagram obtained experimentally and show the presence of a non-Fermi Liquid region at temperatures above the nematic phase.

description: We provide new constraints on the connection between galaxies in the local universe, identified by the Sloan Digital Sky Survey (SDSS), and dark matter halos and their constituent substructures in the $Λ$CDM model using WMAP7 cosmological parameters. Predictions for the abundance and clustering properties of dark matter halos, and the relationship between dark matter hosts and substructures, are based on a high-resolution cosmological simulation, the Bolshoi simulation. We associate galaxies with halos and subhalos using subhalo abundance matching, performing a comprehensive analysis which investigates the underlying assumptions of this technique including (a) which halo property is most closely associated with galaxy stellar masses and luminosities, (b) how much scatter is in this relationship, and (c) how much subhalos can be stripped before their galaxies are destroyed. The models are jointly constrained by new measurements of the projected two-point galaxy clustering and the observed conditional stellar mass function of galaxies in groups. The data put tight constraints on the satellite fraction of galaxies as a function of galaxy stellar mass, on the scatter between halo and galaxy properties, and on the underlying conditional stellar mass function. These data rule out several halo properties commonly used in abundance matching, largely because the satellite fractions in the models disagree with those data. We show that an abundance matching model that associates galaxies with the peak circular velocity of their halos is in good agreement with the data, when scatter of $0.20 \pm 0.03$ dex in stellar mass at a given peak velocity is included. This will yield important constraints for galaxy formation models, and also provides encouraging indications that the galaxy--halo connection can be modeled with sufficient fidelity for future precision studies of the dark Universe.

description: Computer-mediated communication is driving fundamental changes in the nature of written language. We investigate these changes by statistical analysis of a dataset comprising 107 million Twitter messages (authored by 2.7 million unique user accounts). Using a latent vector autoregressive model to aggregate across thousands of words, we identify high-level patterns in diffusion of linguistic change over the United States. Our model is robust to unpredictable changes in Twitter's sampling rate, and provides a probabilistic characterization of the relationship of macro-scale linguistic influence to a set of demographic and geographic predictors. The results of this analysis offer support for prior arguments that focus on geographical proximity and population size. However, demographic similarity -- especially with regard to race -- plays an even more central role, as cities with similar racial demographics are far more likely to share linguistic influence. Rather than moving towards a single unified "netspeak" dialect, language evolution in computer-mediated communication reproduces existing fault lines in spoken American English.

description: The U.S. Atlantic Pelagic Longline fleet operates throughout the northwestern Atlantic Ocean, including along the U.S. coast from the Gulf of Mexico to New England, the waters of the Caribbean, and in international waters of the North Atlantic Ocean. The Atlantic longline fleet is defined as a Category I fishery under the Marine Mammal Protection Act, and it is also the subject of management under the Endangered Species Act due to interactions with leatherback (Dermochelys coriacea) and loggerhead (Caretta caretta) turtles. Total bycatch of marine mammals and turtles in the longline fishery was estimated for 2012 using data from the pelagic longline fishery observer program and a mandatory fishery logbook reporting program. We applied a delta-lognormal approach to estimate region specific and total annual interactions with protected species in the fishery. During 2012 , there were an estimated 596.2 (424.7-837.0 [95% CI]) interactions with leatherback turtles and 680.7 (518.0-894.5 [95% CI]) interactions with loggerhead turtles. The primary marine mammals interacting with this fishery were pilot whales (Globicephala sp.) with an estimated 242.6 (145.8-404.0 [95% CI]) interactions with unspecified pilot whales and an additional 10.0 ( 2.0-51.0 [95% CI]) interactions with genetically identified short-finned pilot whales. Potential sources of bias and uncertainty in these bycatch estimates are discussed.

description: Excerpts from the report: Railcars and trailers equipped for the transport of fresh produce in modified atmospheres have been available to lettuce shippers on the west coast since about 1964. Some of these modified-atmosphere systems have been tested previously by the U.S. Department of Agriculture. One such system introduces nitrogen into the load compartment during transit to refrigerate the load and also to maintain a low oxygen (O2) level. Another system previously tested introduces nitrogen (N2) into the load compartment, during transit only, to maintain a low O2 level; the load in this system is refrigerated by conventional mechanical equipment. A third system for maintaining modified atmospheres in transit was tested in 1967 and 1968 by the USDA for lettuce shipments. In this system the O2 concentration is lowered by purging the load compartment with nitrogen after the car or trailer is loaded. No additional nitrogen is introduced during transit. After the initial purge, carbon monoxide (CO) is also introduced into the car or trailer and lime is placed in the vehicles to absorb the carbon dioxide (CO2) produced by the lettuce during respiration. The vehicles are tightly sealed to reduce air leakage through doors, drains, and other openings. This report presents the results of tests conducted to determine the effectiveness of this particular system in maintaining the market quality of lettuce and to further evaluate the merits of modified atmospheres for lettuce during transcontinental shipment.

description: We have perturbed Wess-Zumino-Witten (WZW) models and also N=(2,2) supersymmetric sigma models on Lie groups by adding a term containing complex structure to their actions. Then, using non-coordinate basis, we have shown that for N=(2,2) supersymmetric sigma models on Lie groups the conditions (from the algebraic point of view) for the preservation of the N=(2,2) supersymmetry impose that the complex structure must be invariant; so only the Abelian Lie algebras admit these deformations preserving the N=(2,2) supersymmetry. Also, we have shown that the perturbed WZW model with this term, using Hermitian (not necessarily invariant) condition, is an integrable model.

description: The dielectric properties of Bi$_2$Te$_3$, a layered compound crystallizing in a rhombohedral structure, are investigated by means of first-principles calculations at the random phase approximation level. A special attention is devoted to the anisotropy in the dielectric function and to the local field effects that strongly renormalize the optical properties in the UV-visible range when the electric field is polarized along the stacking axis. Furthermore, both the Born effective charges for each atom and the zone center phonon frequencies and eigenvectors needed to describe the dielectric response in the infrared range are computed. Our theoretical near-normal incidence reflectivity spectras in both the UV-visible and infrared range are in fairly good agreement with the experimental spectras, provided that the free carriers Drude contribution arising from defects is included in the infrared response. The anisotropic plasmon frequencies entering the Drude model are computed within the rigid band approximation, suggesting that a measurement of the reflectivity in the infrared range for both polarizations might allow to infer not only the type of doping but also the level of doping.

This optical system is similar to the Young double-slit experiment. The coherent wave fronts from a source on the lens plane can form diffraction pattern on the observer plane. This diffraction pattern has two modes from the close- and wide-pair images. From the observational point of view, we study the possibility of detecting this effect through the Square Kilometer Array (SKA) project in the resonance and high magnification channels of binary lensing. While the red giant sources do not seem satisfy the spatial coherency condition, during the caustic crossing, a small part of source traversing the caustic line can produce coherent pair images. Observations of wave optics effect in the longer wavelengths accompanied by optical observations of a microlensing event provide extra information from the parameter space of the planet. These observations can provide a new basis for study of exoplanets.

description: Excerpts from the report: Most growers in Florida use "mule trains" to harvest and pack celery in the field. This harvesting and packing system requires many workers. A prototype handling system based on a central packing and precooling plant was designed and evaluated. A system engineering study was made of the central packing and precooling plant, and tests of system components were completed. Components of the study included: (1) Mechanical cutting and harvesting in the field; (2) hauling celery in bulk from the field to the packinghouse and dumping into a large water tank at the packinghouse; (3) mechanical weigh-sizing celery stalks; (4) manual place-packing celery stalks into crates; (5) mechanical inplant handling with fork trucks; and (6) unit-load precooling.

description: For every Matrix Product State (MPS) one can always construct a so-called parent Hamiltonian. This is a local, frustration free, Hamiltonian which has the MPS as ground state and is gapped. Whenever that parent Hamiltonian has a degenerate ground state (the so-called non-injective case), we construct another 'uncle' Hamiltonian which is local and frustration free but gapless, and its spectrum is $\R^+$. The construction is obtained by linearly perturbing the matrices building up the state in a random direction, and then taking the limit where the perturbation goes to zero. For MPS where the parent Hamiltonian has a unique ground state (the so-called injective case) we also build such uncle Hamiltonian with the same properties in the thermodynamic limit.

Functional renormalisation group for few-nucleon systems: SU(4) symmetry and its breaking

description: We apply the functional renormalisation group to few-nucleon systems. Our starting point is a local effective action that includes three- and four-nucleon interactions, expressed in terms of nucleon and two-nucleon boson fields. The evolution of the coupling constants in this action is described by a renormalisation group flow. We derive these flow equations both in the limit of exact Wigner SU(4) symmetry and in the realistic case of broken symmetry. In the symmetric limit we find that the renormalisation flow equations decouple, and can be combined into two sets, one of which matches the known results for bosons, and the other result matches the one for fermions with spin degrees only. The equations show universal features in the unitary limit, which is obtained when the two-body scattering length tends to infinity. We calculate the spin-quartet neutron-deuteron scattering length and the deuteron-deuteron scattering lengths in the spin-singlet and quintet channels.

description: We give another definition of orbital free entropy introduced by Hiai, Miyamoto and us, which does not need the hyperfiniteness assumption for each given random multi-variable. The present definition is somehow related to one of its several recent `generalizations' due to Biane and Dabrowski, but completely agrees with the original definition and much closer to the original approach.

The possibilities and limitations of constructivist practice in pre-service teacher education in mathematics: Foucault, action research and pedagogical desire

Poststructuralism

description: This study investigates the possibilities and limitations of "constructivist" methods of teaching in a mathematics "methods" course in pre-service teacher education. The research undertaken responds to the Discipline Review of Teacher Education in Mathematics and Science (1989, p.17) which states that teachers of mathematics must themselves "have learned mathematics by constructing their own knowledge through discovery, exploration and problem solving in relevant and supportive environments". In the initial cycles of the research I concentrated on the implementation of "constructivist" practice informed by Habermas' (Can and Kemmis, 1986) critical social theory. I found liberal humanistic assumptions of the individual and knowledge within action research and constructivism problematic in that they did not afford any way of making sense of many of the actions and practices of myself and students. I turned to Foucauldian genealogy for a post-structuralist theorisation of power-knowledge operating within the discourse of constructivist mathematics constituting subjectivities and effecting instances of marginalisation. In the third and final cycle of the research I moved hesitantly towards an understanding of myself and students as discursively constituted, variously positioned and positioning others within the discourse. Epistemologically I began to recognise and appreciate both knowledge as cognitive construct, and a knowing or knowledge as production of meaning. That is, as students constructed the authoritative mathematical and pedagogical knowledges, meanings were also produced which were at times discriminatory. Concluding chapters focus on the production of meaning within myself and students as pedagogical desire. With reference to my practice, I reflect on the importance of distinguishing between discourse as a linguistic function and discourse in the Foucauldian sense as the operation of power-knowledge within practice if teacher education is to move beyond its present conservative influence on students. That is, perhaps teacher education in mathematics needs to move beyond talking differently about mathematics, for example constructivist mathematics or mathematics from minority cultures, to an emphasis on being differently in mathematics through affording students the space to examine meanings produced through the operation of power-knowledge as unquestioned liberal-humanistic assumptions of the individual in constructivist pedagogy and collaborative action research.
State Policies And Pakistani Migrant Organisations In Toronto And Nyc

description: Abstract

This paper examines how different ‘contexts of reception’ in Toronto and NYC shape the size, programmatic domain (social, cultural, economic, political), and geographic scope of action (local vs. transnational) of non-profit organisations serving the Pakistani immigrant community. Existing literature tends to employ a one-sided focus on the role of state-policies in determining the prevalence of immigrant organisations. This literature is also divided into two epistemic camps, one focusing on organisations promoting settlement/incorporation and others on transnational organisations. This study addresses these limitations by examining how state-policies, socioeconomic incorporation, community characteristics and societal attitudes combine to shape the composition of an immigrant group’s collective organisational space – comprised of incorporation and transnationally-oriented organisations. Data come from a new original database of the universe of Pakistani non-profit organisations based in Toronto and New York and from qualitative data gathered in both cities. Contrary to our expectations and previous research, we find that state-sponsored multiculturalism is not associated with a larger or more transnational Pakistani organisational space in Toronto. Rather, the size, programmatic domain and geographic scope of Pakistani organisational spaces are determined by the intersection of state-policies and the immigrant community’s socioeconomic incorporation ­– where the more affluent New Yorker Pakistani community is associated with a larger and more transnational organisational space. Findings also reveal tensions between locally- and transnationally-oriented organisations in both cities, reflecting growing fragmentation between affluent cosmopolitan, immigrant elites and the impoverished segments of the Toronto and NYC Pakistani communities.
Instructional Coaching and State Early Care and Education Policies: Inclusion, Alignment, and Evidence-Based Practices

subject: Early Childhood Education

description: Study Purpose/Background and rationale: The study aims to fill a gap in the early care and education (ECE) research field by systematically analyzing ECE state-level policies to determine whether and how coaching (i.e., individualized professional development) is included, which specific coaching components (e.g., dosage, content, strategies) are provided, whether the coaching policies and programs are evidence or research-based, and the extent to which state-level agency policies are aligned with each other. To accomplish this goal, we rely on innovative policy analysis using existing data from several sources including states’ CCDF plans, state pre-K policy documents, and QRIS policies and guidelines. We specifically focus on ECE center-based policies when distinctions are made between home and center-based programs as more children are served in center-based programs and most preschool aged children in nonparental care are enrolled in some type of center-based care (Cui & Natzke, 2020). Further, in many states, pre-K is offered in a variety of settings including community based child care programs, making the study of policy alignment between the pre-K policies and center-based child care regulations particularly important. Such a policy analysis approach, to our knowledge, is not widely used within the ECE field, but recent research suggests that analyzing policy documents for alignment has the potential to illuminate where misalignment may occur in state-level policies and raises important questions about how state systems can further coordinate to create streamlined PD systems and QI processes, as well as clear policy documents for ECE providers (Buell et al., under review; Whitaker et al., 2022).
