description: Measures of associations have been widely used for describing the statistical relationships between two sets of variables. Traditional association measures tend to focus on specialized settings (specific types of variables or association patterns). Based on an in-depth summary of existing measures, we propose a general framework for association measures unifying existing methods and novel extensions based on kernels, including practical solutions to computational challenges. The proposed framework provides improved feature selection and extensions to a variety of current classifiers. Specifically, we introduce association screening and variable selection via maximizing kernel-based association measures. We also develop a backward dropping procedure for feature selection when there are a large number of candidate variables. We evaluate our framework using a wide variety of both simulated and real data. In particular, we conduct independence tests and feature selection using kernel association measures on diversified association patterns of different dimensions and variable types. The results show the superiority of our methods to existing ones. We also apply our framework to four real-word problems, three from statistical genetics and one of gender prediction from handwriting. We demonstrate through these applications both the de novo construction of new kernels and the adaptation of existing kernels tailored to the data at hand, and how kernel-based measures of associations can be naturally applied to different data structures including functional input and output spaces. This shows that our framework can be applied to a wide range of real world problems and work well in practice.

description:
An innovative glass substrate surface technology including integrated micro-electro-mechanical systems (MEMS) is presented as an advanced light modulation, heat control, and energy management system. This smart technology is based on millions of metallic micromirrors per square meter fabricated on the glass surface, which are arranged in arrays and electrostatically actuated. The smart window application exploits an elaborate MEMS glass technology for active daylight steering and energy management in buildings, enabling energy saving, CO2 emission reduction, a positive health impact, and improved well-being. When light interacts with a glass substrate that has regular, repetitive patterning at the microscopic scale on its surface, these microstructures can cause the diffraction of the transmitted light, resulting in the potential deterioration of the view quality through the smart glass. A reduction in optical artifacts for improved clear view is presented by using irregular geometric micromirror apertures. Several non-periodic, irregular micromirror aperture designs are compared with corresponding periodic regular designs. For each considered aperture geometry, the irregular array reveals a reduction in optical artifacts and, therefore, by far a clearer view than the corresponding regular array. A systematic and comprehensive study was conducted through design, simulation, technological fabrication, experimental characterization, and analysis.

description: We report on a fully self-consistent Hartree-Fock calculation of interaction effects on the Moiré flat bands of twisted bilayer graphene, assuming that valley U(1) symmetry is respected. We use realistic band structures and interactions and focus on the charge neutrality point, where experiments have variously reported either insulating or semimetallic behavior. Restricting the search to orders for which the valley U(1) symmetry remains unbroken, we find three types of self-consistent solutions with competitive ground state energy (i) insulators that break $C_2 {\mathcal T}$ symmetry, including valley Chern insulators (ii) spin or valley polarized insulators and (iii) rotation $C_3$ symmetry breaking semimetals whose gaplessness is protected by the topology of the Moiré flat bands. We find that the relative stability of these states can be tuned by weak strains that break $C_3$ rotation. The nematic semimetal and also, somewhat unexpectedly, the $C_2 {\mathcal T}$ breaking insulators, are stabilized by weak strain. These ground states may be related to the semi-metallic and insulating behaviors seen at charge neutrality, and the sample variability of their observation. We also compare with the results of STM measurements near charge neutrality.

Geometric Interpretation of Chaos in Two-Dimensional Hamiltonian Systems

Subjects: subject: Astrophysics (astro-ph)
subject: Chaotic Dynamics (nlin.CD)

description: Time-independent Hamiltonian flows are viewed as geodesic flows in a curved manifold, so that the onset of chaos hinges on properties of the curvature two-form entering into the Jacobi equation. Attention focuses on ensembles of orbit segments evolved in 2-D potentials, examining how various orbital properties correlate with the mean value and dispersion, and k, of the trace K of the curvature. Unlike most analyses, which have attributed chaos to negative curvature, this work exploits the fact that geodesics can be chaotic even if K is everywhere positive, chaos arising as a parameteric instability triggered by regular variations in K along the orbit. For ensembles of fixed energy, with both regular and chaotic segments, simple patterns connect the values of and k for different segments, both with each other and with the short time Lyapunov exponent X. Often, but not always, there is a near one-to- one correlation between and k, a plot of these quantities approximating a simple curve. X varies smoothly along this curve, chaotic segments located furthest from the regular regions tending systematically to have the largest X's. For regular orbits, and k also vary smoothly with ``distance'' from the chaotic phase space regions, as probed, e.g., by the location of the initial condition on a surface of section. Many of these observed properties can be understood qualitatively in terms of a one-dimensional Mathieu equation.

Kids Can Screw Up Their Parents, Too: An Analysis of the Reciprocal Influences Between Maternal Depressive Symptoms and Child Problem Behaviors From Child Age 2 to 15

description: In spite of theoretical models representing a bidirectional pattern of influence between children and mothers (Sameroff & MacKenzie, 2003), few comprehensive longitudinal studies have examined how maternal psychological functioning and child behavior relate to each other over time. This study explored the transactional relationship between child problem behavior (i.e., internalizing and externalizing) and maternal depressive symptoms from toddlerhood to adolescence. The transactional dynamic was conceptualized in two ways—(a) parallel growth and (b) bidirectional effects—in terms of timing, direction, and the magnitude of effects, as well as how effects were moderated by gender and level of maternal depressive symptoms. Data were drawn from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,179). Using advanced statistical techniques in the structural equation modeling framework, such as multivariate latent growth curve models, latent class analyses, and fully autoregressive cross-lagged models, these findings demonstrate that in contrast to the traditional unidirectional maternal effects framework, the transactional dynamic more accurately represents the relationship between maternal and child functioning.
      Specifically, results indicated that the relationship between child internalizing behavior and maternal depressive symptoms was more strongly characterized as a parallel growth dynamic, whereas child externalizing behavior and maternal depressive symptoms more consistently exerted mutual influence. Bidirectional effects were not restricted to periods of heightened psychosocial stress, such as toddlerhood, adolescence, or transitions in school. Gender and level of maternal depressive symptoms moderated this bidirectional association. Maternal depressive symptoms had the largest effect on child internalizing behavior in middle childhood. Children’s externalizing behaviors in toddlerhood and early childhood had a strong effect on maternal depressive symptoms; the magnitude of this effect was greater than any other pathway from children to mothers or mothers to children. Findings suggest that children’s externalizing and internalizing behavior may serve as a potential risk factor for future increases in maternal depressive symptoms.

description: In this paper we classify all 4+1 cosmological models where the spatial hypersurfaces are connected and simply connected homogeneous Riemannian manifolds. These models come in two categories, multiply transitive and simply transitive models. There are in all five different multiply transitive models which cannot be considered as a special case of a simply transitive model. The classification of simply transitive models, relies heavily upon the classification of the four dimensional (real) Lie algebras. For the orthogonal case, we derive all the equations of motion and give some examples of exact solutions. Also the problem of how these models can be compactified in context with the Kaluza-Klein mechanism, is addressed.

Expressions of fluxes of energy and angular momentum carried by gravitational waves across these horizons are obtained. Fluxes are local, the energy flux is positive and change in the horizon area is related to these fluxes. The flux formulae also give rise to balance laws analogous to the ones obtained by Bondi and Sachs at null infinity and provide generalizations of the first and second laws of black hole mechanics.

description: Kinetic inductance detectors (KIDs) are superconducting thin-film microresonators that are sensitive photon detectors.
      These detectors are a candidate for the next generation of experiments designed to measure the polarization of the cosmic microwave background (CMB).
      I discuss the basic theory needed to understand the response of a KID to light, focusing on the dynamics of the quasiparticle system.
      I derive an equation that describes the dynamics of the quasiparticle number, solve it in a simplified form not previously published, and show that it can describe the dynamic response of a detector.
      Magnetic flux vortices in a superconducting thin film can be a significant source of dissipation, and I demonstrate some techniques to prevent their formation.
      Based on the presented theory, I derive a corrected version of a widely-used equation for the quasiparticle recombination noise in a KID.
      I show that a KID consisting of a lumped-element resonator can be sensitive enough to be limited by photon noise, which is the fundamental limit for photometry, at a level of optical loading below levels in ground-based CMB experiments.
      Finally, I describe an ongoing project to develop multichroic KID pixels that are each sensitive to two linear polarization states in two spectral bands, intended for the next generation of CMB experiments.
      I show that a prototype 23-pixel array can detect millimeter-wave light, and present characterization measurements of the detectors.

description: We summarize the basics of the loop representation of quantum gravity and describe the main aspects of the formalism, including its latest developments, in a reorganized and consistent form. Recoupling theory, in its graphical Temperley-Lieb-Kauffman formulation, provides a powerful calculation tool in this context. We describe its application to the loop representation in detail. Using recoupling theory, we derive general expressions for the spectrum of the quantum area and the quantum volume operators. We compute several volume eigenvalues explicitly. We introduce a scalar product with respect to which area and volume are symmetric operators, and (the trivalent expansions of) the spin network states are orthogonal.

description: The main objective of this Article is to map and categorize the CJEU's case law relating to EMU. Although in purely quantitative terms, this is not a huge task, there are already enough relevant court rulings, up to 31 December 2020, to enable the establishment of a taxonomy distinguishing between four different categories of EMU-related case law. The first and foremost category will comprise cases dealing with the fundamentals of EMU, including clarifying the distinction between monetary policy and economic and other policies. This category includes a number of well-known cases of great political importance, such as Pringle ECLI:EU:C:2012:756, Gauweiler ECLI:EU:C:2015:400, Weiss ECLI:EU:C:2018:1000, Kotnik ECLI:EU:C:2016:570 and Florescu ECLI:EU:C:2017:448. A second category relates to the nature of the EU as a system of multilevel governance and the need to determine whether the competence to act is at national or Union level or a mix of the two. Cases in point include UK v ECB (security clearing) ECLI:EU:T:2015:133, Berlusconi ECLI:EU:C:2018:1023 and Rimšēvičs ECLI:EU:C:2019:139. A third group of cases relates to issues of responsibility and liability, including questions of the liability of "abnormal" EU bodies or settings such as the Troika or the Euro Group. Fourth, especially the Banking Union has triggered cases relating to prudential supervision and other more technical issues. This analysis will be completed by some concluding remarks, including the question of the intensity of judicial control (standard of review), viewing the EMU case law in a broader context.

description: Native plants that naturally establish and thrive in sand (particularly on active dunes) are adapted to dry, nutrient deficient habitats and have evolved a tolerance to burial and exposure. In 1995, Wild Rose Consulting, Inc. and Syncrude Canada initiated a preliminary study to evaluate psammophilous plants (native to the local boreal ecoregion) for establishment and growth on oil sand tailings near Fort McMurray. Alberta. Seeds and roots of Astragalus aboriginum, Carex siccata, Deschampsia mackenzieana, Elymus mollis, Hierochloe odorata, Hudsonia tomentosa, Salix brachycarpa, and Stellaria arenicola were collected from three active dune sites in northern Alberta and Saskatchewan (Grande Prairie, Lesser Slave Lake, and Lake Athabasca). A preliminary survey of mycorrhizal symbionts was undertaken. Germination was tested after seeds were dried and cleaned. Species with adequate germination were tested for growth in tailing sands under controlled conditions. Astragalus aboriginum, Deschampsia mackenzieana, Salix brachycarpa, and Stellaria arenicola grew well in tailing sands in the greenhouse and were placed in field plots in 1996 (transplanted and seeded). Average survival of transplants in field plots was 80% or greater after two months in the first year. Deschampsia mackenzieana and Astragalus aboriginum seedlings were also emerging. Plants were divided into three groups based on their mycorrhizal symbionts: Elymus mollis, Deschampsia mackenzieana, and Hierochloe odorata formed vesicular-arbuscular mychorrizas, Hudsonia tomentosa and Salix brachycarpa were ectomycorrhizal, and Stellaria arenicola and Carex siccata lacked recognizable mycorrhizae.

description: Water trading in the Murray–Darling Basin of Australia has developed to the point where it is a common adaptation tool used by irrigators, making it an apt case study to elicit the marginal value of irrigation water and irrigators’ risk preferences in two key industries with differing levels of water dependence. Our data come from large-scale and representative surveys of irrigated broadacre and horticultural farms in the Murray–Darling Basin over a 6-year period. The marginal contribution of irrigation water to profit is estimated at $547 and $61/ML on average in horticulture and broadacre, respectively. Horticultural irrigators are found to be averse to the risk of large losses (downside risk) while broadacre irrigators are averse to the variability (variance) of profit.

Outside the shell, the spacetime is assumed to be described by the Schwarzschild metric, while inside the shell it is taken to be the flat Minkowski space. Using zeta function regularization and heat kernel coefficients we isolate the divergent contributions of the Casimir energy inside and outside the shell, then using the renormalization procedure of the bag model the divergent parts are cancelled, finally obtaining a renormalized expression for the total Casimir energy.

description: Broadacre agriculture is a major emitter of greenhouse gases (GHG). To improve efficiency of climate change policies, we need to know the marginal abatement costs of agricultural GHG. This article combines calculations of on-farm GHG emissions with an input-based distance function approach to estimate the marginal abatement costs for a broadacre farming system in the Great Southern Region of Western Australia. The results show that, in the study region, the average marginal abatement cost for the 1998–2005 periods was $29.3 per tonne CO2-e. Farms with higher crop output shares were found to have higher marginal abatement costs. Overall, our results indicate that broadacre agriculture is among the lowest cost sources of GHG mitigation.

description: Although there have been serious efforts to decrease the rates of premature infant
births in the United States, such figures have stayed constant throughout the years
(Blackwell‐Sachs and Blackburn, 2003). As preventative measures have yielded few results,
it is crucial for scientists, policy makers and physicians alike to focus their efforts on
maximizing care once the premature infant has been born. Unfortunately, infants born
before 28 weeks have a much lower rate of survival then babies born at full term (Kelly,
2006). By optimizing standardized care, there would be added benefits to alleviate both
costly hospital stays, reduce familial stress and hopefully increase developmental outcomes
for the newborn on a physical, emotional and psychological level. As more than 320,000
newborns are relegated to the care of a physician every year (Kelly, 2006) this issue is both
vast and foreseeable, which entertains the notion that research can provide aid to possibly
reduce some of these issues.

description: Heusler compounds are promising materials for spintronics with adjustable electronic properties including 100% spin polarization at the Fermi energy. We investigate the electronic states of AlOx capped epitaxial thin films of the ferromagnetic half metal Co2MnSi ex-situ by soft X-ray angular resolved photoemission spectroscopy (SX-ARPES). Good agreement between the experimental SX- ARPES results and photoemission calculations including surface effects was obtained. In particular, we observed in line with our calculations a large photoemission intensity at the center of the Brillouin zone, which does not originate from bulk states, but from a surface resonance. This provides strong evidence for the validity of the previously proposed model based on this resonance, which was applied to explain the huge spin polarization of Co2MnSi observed by angular-integrating UV-photoemission spectroscopy.

description: Vehicle-to-Vehicle (V2V) communications are being proposed, tested and deployed to improve road safety and traffic efficiency. However, the automotive industry poses strict requirements for safety-critical applications, that call for reliable, low latency and high data rate communications. In this context, it is widely agreed that both Radio-Frequency (RF) technologies at mmWaves and Free-Space Optics (FSO) represent promising solutions, although their performances are severely degraded by transmitter-receiver misalignment due to the challenging high-mobility conditions. By combining RF and FSO technologies, this paper proposes a FSO-based V2V communication system where the pointing coordinates of laser sources are based on vehicle's information exchanged over a reliable low-rate RF link. Numerical simulations demonstrate that such compensation mechanism is mandatory to counteract the unavoidable misalignments induced by vehicle dynamics, and thus to enable FSO technology for V2V communications even in high mobility scenarios.

description: In the present study we consider planar piecewise linear vector fields with two zones separated by the straight line $x=0$. Our goal is to study the existence of simultaneous crossing and sliding limit cycles for such a class of vector fields. First, we provide a canonical form for these systems assuming that each linear system has center, a real one for $y<0$ and a virtual one for $y>0$, and such that the real center is a global center. Then, working with a first order piecewise linear perturbation we obtain piecewise linear differential systems with three crossing limit cycles. Second, we see that a sliding cycle can be detected after a second order piecewise linear perturbation. Finally, imposing the existence of a sliding limit cycle we prove that only one additional crossing limit cycle can appear. Furthermore, we also characterize the stability of the higher amplitude limit cycle and of the infinity. The main techniques used in our proofs are the Melnikov method, the Extended Chebyshev systems with positive accuracy, and the Bendixson transformation.

description: It is first shown that the observational light curve data of R Scuti, a star of the RV Tau type, is not multi-periodic, and that it cannot have been generated by a linear stochastic (AR) process. By default, the signal must be a manifestation of deterministic chaos. We use a novel nonlinear time-series analysis, the global flow reconstruction technique, to probe the properties of the irregular pulsation cycles. We show in particular that the chaotic dynamics of this star's complicated lightcurve is captured by a simple 4D polynomial map or flow (4 first order ODEs). Importantly also, the method allows us to quantify an irregular signal which has the potential benefit for extracting novel stellar constraints from an irregular light-curve. Finally, from the low dimensionality 4 of the flow we can infer a simple physical picture of the pulsations, and arguments are presented that the pulsations of R Sct are the result of the nonlinear interaction of two vibrational normal modes of the star.

The Excavation of Barrows V-IX at West Heath, Harting. 1980
Creators: name: Drewett, P
Publisher: name: Archaeology Data Service
Year: 2021

description: Sussex Archaeological Collections, 123, 35-60
description: The West Heath barrow group consisted of a nucleated cluster of nine mounds together with three outliers. Barrows I-IV were excavated during 1973-5. This report describes the excavation of Barrows V-IX undertaken prior to their destruction by sand quarrying in 1980. Barrows V, VIII and IX contained no burials and were simple turf mounds. Barrow VII consisted of two ditches encircling a disturbed burial pit. Barrow VI, although only a simple turf stack, covered a multiple burial pit containing collared urns and cremations. Considerable environmental data was recovered from a study of the soils, pollen and macroscopic plant remains. A series of Carbon 14 dates suggests a date range of c. 2100- 1450 B.C. for the development of the cemetery.
Demonstrating self-sustaining vegetation : Granby Tailings, Princeton, B.C.

description: The Granby Tailings, located immediately east of the Town of Princeton, are a highly visible reminder of the original Granby Copper and Consolidated Company that operated in the Princeton area between 1922 and 1956. This seventy eight hectare tailings pile lay barren, void of vegetative cover for almost forty years, creating aesthetic, wind erosion, and chronic dust problems for the local citizens. Low annual precipitation (35 cm), combined with the poor moisture and nutrient retention of the inert tailings, had frustrated the efforts of both man and nature to revegetate the tailings site. In 1992, the Greater Vancouver Regional District in partnership with the Town of Princeton established four demonstration plots on the Granby Tailings, to show how mine spoils can be successfully reclaimed using biosolids (treated sewage sludge). The tailings were enriched with biosolids, seeded, and monitored over the past five years. Extensive soil, water, and vegetation sampling in and around the plots, before and following the applications, confirmed that biosolids is a safe and effective soil amendment. The biosolids provided organic matter and essential plant nutrients that helped establish a healthy, mixed grass and legume cover, which in turn eliminated the dust and wind erosion problems, and reclaimed the area for recreation, cattle, and wildlife use. Based on the results from the initial demonstration plots, Princeton Town Council and the Economic Development Commission supported the GVRD's proposal in 1994 to landscape the entire Granby Tailings site using biosolids. A total of fifty six hectares of flat pond surfaces and twenty hectares of steep slide slopes were reclaimed over two years. The vigorous growth has provided increased opportunities for forage production, seasonal cattle grazing, and wildlife habitat. Even more exciting is the Town's plans to expand the local golf course onto the tailings site. The results of the monitoring program associated with the demonstration plots, as well as a brief overview of the full scale reclamation operation are presented.

Knot Floer Homology and Categorification

Publisher: name: Columbia University

Subjects: subject: Mathematics
subject: FOS: Mathematics

description: With the goal of better understanding the connections between knot homology theories arising from categorification and from Heegaard Floer homology, we present a self-contained construction of knot Floer homology in the language of HOMFLY-PT homology. Using the cube of resolutions for knot Floer homology defined by Ozsváth and Szabó, we first give a purely algebraic proof of invariance that does not depend on Heegaard diagrams, holomorphic disks, or grid diagrams. Then, taking Khovanov's HOMFLY-PT homology as our model, we define a category of twisted Soergel bimodules and construct a braid group action on the homotopy category of complexes of twisted Soergel bimodules. We prove that the category of twisted Soergel bimodules categorifies the Hecke algebra with an extra indeterminate and its inverse adjoined. The braid group action, which is defined via twisted Rouquier complexes, is simultaneously a natural extension of the knot Floer cube of resolutions and a mild modification of the action by Rouquier complexes used by Khovanov in defining HOMFLY-PT homology. Finally, we introduce an operation Qu to play the role that Hochschild homology plays in HOMFLY-PT homology.  We conjecture that applying Qu to the twisted Rouquier complex associated to a braid produces the knot Floer cube of resolutions chain complex associated to its braid closure. We prove a partial result in this direction.
Gravitational waveforms from inspiralling compact binaries to second-post-Newtonian order

description: The two independent ``plus" and ``cross" polarization waveforms associated with the gravitational waves emitted by inspiralling, non-spinning, compact binaries are presented, ready for use in the data analysis of signals received by future laser interferometer gravitational-wave detectors such as LIGO and VIRGO. The computation is based on a recently derived expression of the gravitational field at the second-post-Newtonian approximation of general relativity beyond the dominant (Newtonian) quadrupolar field. The use of these theoretical waveforms to make measurements of astrophysical parameters and to test the nature of relativistic gravity is discussed.

description: This qualitative research study focused on Asian fathers living in the United States. It raised issues about the social perceptions of minority immigrants and provided alternative interpretations of the acculturation of Korean fathers who have been neglected in diverse social and educational discourses. In particular, this study looked at recent Korean immigrants who settled in America after 2008. By doing so, this work demonstrated the distinct demographical and socioeconomic hallmarks (e.g., better educational opportunities, economic prosperity, and cultural openness) of immigration in the United States. This study is organized into two sections: a general survey which gathered information about current issues and marginalization and clarified the stereotypes facing Korean immigrants; and in-depth interviews and participative observations which collected stories and reflections from and about Korean immigrant fathers. I endeavored to (a) observe the Korean father, the family member who is most neglected by academic discourse on immigrant families; (b) identify the concerns of the modern, minority immigrant; and (c) collect the voices of people who undergo acculturation or transformative adaptation of a new culture. The overall significance of this study is that it presents new understanding of the life patterns of Korean fathers who reside in the United States. Research participants showed a tendency to emphasize the role of a social safety network board for racial community while being individualistic in personal matters. Moreover, the social position of fathers has changed internally and externally. Internal changes engendered through specific social conditions such as identity, parenting, religion, father awareness, and food rituals and memory were analyzed as the main factors for completing the overall transformation. Lastly, the personal experiences or traits that appeared in the process of memory and consciousness were essential for creating the defining qualities of fathers in perceptions of the Korean father figure. Through a descriptive analysis, I uncovered what the four participants, who had different immigration trajectories, shared as commonalities and differences. Transformation by factors other than culture seemed to be an important variable. The interviewees’ anecdotes confirmed the roles of memory and individual response to a complex series of cultural adaptations and provided important implications.

description: Kuranishi atlases were introduced by McDuff and Wehrheim as a means to build a virtual fundamental cycle on moduli spaces of J-holomorphic curves and resolve some of the challenges in this field. This thesis considers genus zero Gromov-Witten invariants on a general closed symplectic manifold. We complete the construction of these invariants using Kuranishi atlases. To do so, we show that Gromov-Witten moduli spaces admit a smooth enough Kuranishi atlas to define a virtual fundamental class in any virtual dimension. In the process, we prove a stronger gluing theorem. Once we have defined genus zero Gromov-Witten invariants, we show that they satisfy the Gromov-Witten axioms of Kontsevich and Manin, a series of main properties that these invariants are expected to satisfy. A key component of this is the introduction of the notion of a transverse subatlas, a useful tool for working with Kuranishi atlases.
