Metastable states of hydrogen: their geometric phases and flux densities

description: We discuss the geometric phases and flux densities for the metastable states of hydrogen with principal quantum number n=2 being subjected to adiabatically varying external electric and magnetic fields. Convenient representations of the flux densities as complex integrals are derived. Both, parity conserving (PC) and parity violating (PV) flux densities and phases are identified. General expressions for the flux densities following from rotational invariance are derived. Specific cases of external fields are discussed. In a pure magnetic field the phases are given by the geometry of the path in magnetic field space. But for electric fields in presence of a constant magnetic field and for electric plus magnetic fields the geometric phases carry information on the atomic parameters, in particular, on the PV atomic interaction. We show that for our metastable states also the decay rates can be influenced by the geometric phases and we give a concrete example for this effect. Finally we emphasise that the general relations derived here for geometric phases and flux densities are also valid for other atomic systems having stable or metastable states, for instance, for He with n=2. Thus, a measurement of geometric phases may give important experimental information on the mass matrix and the electric and magnetic dipole matrices for such systems. This could be used as a check of corresponding theoretical calculations of wave functions and matrix elements.

description: (Abridged) Planetary nebulae (PNe) around Wolf-Rayet [WR] central stars ([WR]PNe) constitute a particular photoionized nebula class that represents about 10% of the PNe with classified central stars. We analyse deep high-resolution spectrophotometric data of 12 [WR]PNe. This sample represents the most extensive analysed so far, at such high spectral resolution. We aim to select the optimal physical conditions in the PNe to be used in ionic abundance calculations that will be presented in a forthcoming paper. We acquired spectra at LCO with the 6.5-m telescope and the MIKE spectrograph, covering a wavelength range from 3350 to 9400 A. The spectra were exposed deep enough to detect, with signal-to-noise ratio higher than three, the weak ORLs of OII, CII, and other species. We detect and identify about 2980 emission lines, which, to date, is the most complete set of spectrophotometric data published for this type of objects. From our deep data, numerous diagnostic line ratios for Te and Ne are determined from CELs, ORLs, and continuum measurements. Densities are closely described by the average of all determined values for objects with ne<10^4 cm-3, and by ne([Cl III]) for the densest objects. For Te, we adopt a three-zone ionization scheme, where the low ionization zone is characterized by Te([NII]), the medium ionization zone by Te([OIII]) and the highest ionization one by Te([ArIV]) when available. We compute Te from the HI Paschen discontinuity and from HeI lines. We do not find evidences of the presence of low-temperature, high-density clumps in our [WR]PNe from the analysis of faint O II and N II plasma diagnostics. The behaviour of Te([OIII])/Te([NII]) being very low for high ionization degrees can be reproduced by a set of combined matter-bounded and radiation-bounded models, however, for the lowest temperature ratios, too high metallicity seem required.

description: Depression, substance abuse, and domestic violence are often considered individual problems but, in fact, the societal costs of these issues are great. For the adults, it is reflected in lost productivity and in high health care costs. Either alone or in combination, these risk factors not only impair the ability to work, they also affect parenting processes, which can hinder children's development. These problems increase the odds that children will enter school without the cognitive, social, and emotional skills and competencies they need to succeed, thus setting the stage for increased placement in special education, grade retention, and ultimately, school drop-out. This synthesis summarizes recent research results and finds a need for more information on two-generation approaches.

description: We study through the time evolution of magnetization the low temperature (T) dynamics of the metastable coexisting phases created by traversing different paths in magnetic field (H) and T space in a shape memory alloy system, Ni$_{45}$Co$_{5}$Mn$_{38}$Sn$_{12}$. It is shown that these coexisting phases consisting of a fraction of kinetically arrested austenite phase and remaining fraction of low-T equilibrium martensitic phase undergo a slow relaxation to low magnetization (martensitic) state but with very different thermomagnetic history-dependent rates at the same T and H. We discovered that, when the nucleation of martensitic phase is initiated at much lower T through the de-arrest of the glass like arrested state contrasted with the respective first order transformation (through supercooling at much higher T), then the long time relaxation rate scales with the non-equilibrium phase fraction but has a very weak dependence on T. This is explained on the basis of the H-T path dependent size of the critical radii of the nuclei and the subsequent growth of the equilibrium phase through the motion of the interface.

description: For most young children, early experiences—sensitive, responsive parents, stable child care situations, and generally supportive emotional experiences—provide the kind of nurturing and stimulation that enables them to develop age-appropriate emotional and cognitive competencies. But there is also a group of young children for whom emotional development does not proceed smoothly, placing the children at risk for poor cognitive, social, and behavioral outcomes. To date, there has been very little systematic attention paid to how to develop policies and practices to promote healthy emotional development in these children. This guide is for policymakers and community leaders who want to craft such policies and improve practices. It paints a portrait of the kinds of young children and families who are in need of preventive, early intervention, or treatment services; highlights why policymakers should invest in such services; describes emerging principles and strategies for what are often called early childhood mental health services; and offers concrete tips from early leaders in these efforts, as well as more general recommendations.
Schopenhauer on Fear

description: text as original form
description: In continual search for the various roots (and routes) of W. thought in regard to making sense of “fear,” the author pursues a preliminary investigation of the great German philosopher Arthur Schopenhauer (1788-1860). He concludes that Schophenhauer’s work is a critical philosophy: (a) underestimated in importance overall in the philosophical canon of W. thinking, (b) it is largely (mis-)interpreted on some important points, especially the stereotyping of its “pessimism” and (c) it is a philosophy ready (with some re-adaptations) for the Anthropocene era of dangerous collapse of ecological and social systems. The author suggests a much larger work of study and writing is still required to bring Schopenhauer’s work alive and in preparation for the 21st century and this technical paper barely touches on the surface of such an exploration.
title: The medical parent: identity formation and community building among parents of medically fragile children in Newfoundland and Labrador

description: This thesis is about the experiences of parents of medically-fragile children. Through a symbolic interactionist lens, I interviewed parents of medically-fragile children in Newfoundland and Labrador using open-ended, qualitative research methods to ascertain how they framed their lived experiences. My data revealed that these parents developed a “medical parent” identity through their interactions with others, and this identity was the lens through which they filtered and interacted with the world. These parents engaged with temporality, boundary work, normalization, and medical knowledge as part of their everyday parenting experiences. My data showed that these parents engage with 13 identifiable hazards as part of performing the medical parent identity, which overlaps and correlates with each other.

Abstract
Avalglucosidase alfa (NEXVIAZYME™; avalglucosidase alfa-ngpt) is a hydrolytic lysosomal glycogen-specific recombinant human α-glucosidase product being developed by Sanofi Genzyme (formerly Genzyme Corporation) for the treatment of Pompe disease. Pompe disease is an autosomal recessive lysosomal storage disease caused by a deficiency of the lysosomal enzyme acid α-glucosidase (GAA), which results in intralysosomal accumulation of glycogen in various tissues. In August 2021, avalglucosidase alfa received its first approval in the USA for the treatment of patients 1 year of age and older with late-onset Pompe disease (GAA deficiency). In July 2021, avalglucosidase alfa received a positive opinion in the EU for long-term enzyme replacement therapy for the treatment of patients with Pompe disease. The drug is under regulatory review in the UK and Japan, and clinical studies are underway in several countries worldwide. This article summarizes the milestones in the development of avalglucosidase alfa leading to this first approval for late-onset Pompe disease.

description: ESA's hard X-ray and soft gamma-ray observatory INTEGRAL is covering the 3 keV to 10 MeV energy band, with excellent sensitivity during long and uninterrupted observations of a large field of view (~100 square degrees), with ms time resolution and keV energy resolution. It links the energy band of pointed soft X-ray missions such as XMM-Newton with that of high-energy gamma-ray space missions such as Fermi and ground based TeV observatories. Key results obtained so far include the first sky map in the light of the 511 keV annihilation emission, the discovery of a new class of high mass X-ray binaries and detection of polarization in cosmic high energy radiation. For the foreseeable future, INTEGRAL will remain the only observatory allowing the study of nucleosynthesis in our Galaxy, including the long overdue next nearby supernova, through high-resolution gamma-ray line spectroscopy. Science results to date and expected for the coming mission years span a wide range of high-energy astrophysics, including studies of the distribution of positrons in the Galaxy; reflection of gamma-rays off clouds in the interstellar medium near the Galactic Centre; studies of black holes and neutron stars particularly in high- mass systems; gamma-ray polarization measurements for X-ray binaries and gamma-ray bursts, and sensitive detection capabilities for obscured active galaxies with more than 1000 expected to be found until 2014. This paper summarizes scientific highlights obtained since INTEGRAL's launch in 2002, and outlines prospects for the INTEGRAL mission.

Marriage--Economic aspects

description: Recent public policy initiatives have encouraged low-income parents to marry as a way to become economically stable. But, the data tell a more complex story. Marriage does not guarantee economic security. Not only do the majority of children in single-parent families have parents who were previously married, more than one in four children with married parents is low income. Even when married, some demographic groups are particularly likely to be low income, which is defined as earning less than twice the poverty level—the minimum necessary to meet families' most basic needs. Among Latinos, more than half of children with married parents are low income. In rural and suburban areas, the majority of low-income children have married parents. Despite high levels of employment, many married parents remain low income. Among children with low-income married parents, a full 95 percent have at least one parent who is employed, and 41 percent have two employed parents.

description: The number of America's children who live in low-income families is growing. In addition, where they live is changing. Children in low-income families are twice as likely to have faced moving in the previous year, compared to children in higher-income families. Two-thirds of children in low-income families live in the West or the South—a substantial increase in those regions from a decade ago. Immigration has fueled some of the change in the West—37 percent of children of recent immigrants lived there. While the vast majority of the children in low-income families move within regions, the majority who move inter-regionally settle in the South. Forty-five percent of children in low-income families who moved to different regions did so for the parents' jobs. Children in low-income families who moved within regions usually did so for housing-related reasons—the most commonly sited was "wanted better housing." In the South and West, children in low-income families are more concentrated in rural areas, but they are more likely to live in urban areas in the Midwest and Northeast. Poverty is growing in suburban areas, although they are substantially less likely to be home to the children of low-income families. This report looks at where children in low-income families live, where and why their families move, and the implications for public policy.

description: Trockenheit ist einer der Hauptfaktoren, die den Ertrag und die Kornqualität mindern können. Trockenstress besitzt einen wichtigen Einfluss auf die Kornkeimung, die Vermehrung, und auch auf die Veredlung der Körner zu Malz. Zwei Gesternmalz-Elitesorten mit unterschiedlichen Strategien zur Trockenstresstoleranz und davon abgeleitete Doppelt-Haploid-Population wurden auf Keimungsraten getestet. Die Körner, die sich an der Mutterpflanze unter Trockenstressbedingungen entwickelt hatten, zeigten eine signifikant schnellere Keimung. Die Zusammenhänge zwischen der Keimrate und den Mälzeigenschaften wurden identifiziert und die genomische Region, welche mit diesem quantifizierbaren Merkmals (QTL) verknüpft war, lokalisiert. Abscisinsäure (ABA) ist das wichtigste abiotische Stress- und Dormanz induzierende Pflanzenhormon, dessen Rolle mit Hilfe von ABA manipulierten transgenen Linien untersucht wurde. Nach terminalem Trockenstress konnte ein verstärkter ABA Abbau in reifen Körner nachgewiesen werde. Dies korrelierte auch mit einer schnelleren Keimung. Die Microarray-basierte Transkriptomanalyse erlaubte es, die für die Keimung essentiellen Transkripte im Embryo und in der Aleuronschicht zu identifizieren sowie Kandidatengene zu identifizieren die für die Mälzqualität von Bedeutung sind.
description: Drought is one of the major factors that limit yield and impairs grain quality, while cereal grain germination has a central role in crop propagation and malting. Two malting elite varieties with distinct drought tolerance mechanisms and their double haploid population were tested for germination rates. Grains that had developed on the mother plant under drought condition showed a significant increase in germination rate. Relations of germination rate with malting traits were identified and confirmed by quantitative trait locus (QTL) detection. Abscisic acid (ABA) is the key abiotic stress and dormancy inducing hormone, and its role was studied using ABA manipulated transgenic lines. After terminal drought stress increased ABA degradation is detected in mature grains, which also showed faster germination behaviour. Microarray based transcriptome analysis enabled to identify germination essential transcripts in the embryo and the aleurone layer as well as candidate genes important for malting quality traits.
The effects of misspecification type and nuisance variables on the behaviors of population fit indices used in structural equation modeling
Creators: name: Mahler, Claudia
Publisher: name: University of British Columbia
Year: 2011

description: The present study examined the performance of population fit indices used in structural equation modeling. Index performances were evaluated in multiple modeling situations that involved misspecification due to either omitted error covariances or to an incorrectly modeled latent structure. Additional nuisance parameters, including loading size, factor correlation size, model size, and model balance, were manipulated to determine which indices’ behaviors were influenced by changes in modeling situations over and above changes in the size and severity of misspecification. The study revealed that certain indices (CFI, NNFI) are more appropriate to use when models involve latent misspecification, while other indices (RMSEA, GFI, SRMR) are more appropriate in situations where models involve misspecification due to omitted error covariances. It was found that the performances of all indices were affected to some extent by additional nuisance parameters. In particular, higher loading sizes led to increased sensitivity to misspecification and model size affected index behavior differently depending on the source of the misspecification.

description: Comprehensive soil and nutrient management on the farm can reduce water pollution. Matching the amount and timing of nutrient applications to the needs of crops is the most cost-effective and efficient way to control nutrient contamination of surface and ground water. Soil conservation practices reduce surface-water pollution, but can increase nitrate leaching through the soil. Misdirected practices, such as excessive or mistimed manure applications, can increase nutrient contamination of surface and ground water. This report uses a field-scale computer simulation model, CREAMS (Chemicals, Runoff, and Erosion from Agricultural Management Systems), to assess pollutant losses from agricultural land to water. A central theme of the analysis is the tradeoff between nutrient loadings in surface water versus ground water.

description: In dieser Arbeit wir eine neue Methode zum Chemical Templating vorgestellt, mit der bulkartige magnetische Eigenschaften von tetragonal verzerrten Heusler-Strukturen in Dünnschichten erzielt werden können. Dies wird dadurch erreicht, dass die Heusler-Dünnfilme auf atomar geordneten CoAl, CoGa, CoGe, CoSn gewachsen werden, die als Grundlage für eine chemische Ordnung innerhalb der Heusler-Strukturen sogar bei Raumtemperatur dienen. Die Mn3Z-Familie von Heusler-Legierungen mit Z = Ge, Sn, Sb zeigt eine exzellente senkrechte Anisotropie-Eigenschaften. Die Richtung der stromgetriebenen Bewegung magnetischer Domänen in Racetracks aus Nanodrähten durch die Bulk-Spinpolarisation der Heusler bestimmt ist. Messung mit magnetischen Feldern in der Filmeebene gezeigt, dass chirale Spin-Bahn-Drehmomente eine Wichtige Rolle spielen. Es wird aufgezeigt, dass dies von einer bulkartigen Dzyaloshinskii-Moriya sowie von einem Spin-Hall-Effekt in dem Chemical-Templating-Schichten herrührt. Die Ergebnisse stellen den ersten Nachweis von Domänenwandbewegung in ultradünnen Heusler-Strukturen dar und dienen somit als ein wichtiger Schritt für die Anwendung von Heusler-Strukturen in der Spinelektronik.
description: In this thesis, is shown a novel chemical templating technique where bulk like magnetic properties in tetragonally distorted Heusler films can be achieved. This is done by growing the Heusler films on atomically ordered CoAl, CoGa, CoGe, CoSn, underlayers that template chemical ordering within the Heusler films, even at room temperature. The Mn3Z family of Heusler alloys is mainly investigated, Z=Ge, Sn, Sb, displaying excellent perpendicular magnetic anisotropy. The current driven domain wall motion direction in nanowire Racetracks from these films is determined by the bulk spin polarization of the Heusler. Moreover, a significant contribution from chiral spin orbit torques is revealed when studied applying in-plane magnetic fields. A bulk in origin Dzyaloshinskii-Moriya interaction and a spin Hall effect from the chemical templating layers are identified. These results are the first demonstration of domain wall motion in ultra-thin Heusler alloys and this work is an important step to enable Heusler spintronic applications.

description: We consider the problem of maximizing the algebraic connectivity of the communication graph in a network of mobile robots by moving them into appropriate positions. We define the Laplacian of the graph as dependent on the pairwise distance between the robots and we approximate the problem as a sequence of Semi-Definite Programs (SDP). We propose a distributed solution consisting of local SDP's which use information only from nearby neighboring robots. We show that the resulting distributed optimization framework leads to feasible subproblems and through its repeated execution, the algebraic connectivity increases monotonically. Moreover, we describe how to adjust the communication load of the robots based on locally computable measures. Numerical simulations show the performance of the algorithm with respect to the centralized solution.

description: While nearly 40 percent of America's children live in low-income families, they face very different demographic conditions depending on the state in which they live. State characteristics, including education levels, family structure, and immigration, contribute to differences in low-income rates among the states.

description: If pairs of new colored particles are produced at the Large Hadron Collider, determining their quantum numbers, and even discovering them, can be non-trivial. We suggest that valuable information can be obtained by measuring the resonant signals of their near-threshold QCD bound states. If the particles are charged, the resulting signatures include photons and leptons and are sufficiently rich for unambiguously determining their various quantum numbers, including the charge, color representation and spin, and obtaining a precise mass measurement. These signals provide well-motivated benchmark models for resonance searches in the dijet, photon+jet, diphoton and dilepton channels. While these measurements require that the lifetime of the new particles be not too short, the resulting limits, unlike those from direct searches for pair production above threshold, do not depend on the particles' decay modes. These limits may be competitive with more direct searches if the particles decay in an obscure way.

description: The goal of the KLOE-2 experiment operating at the upgraded DAΦNE e+e-collider is to collect an integrated luminosity of about 20 fb-1 during 3-4 years of running. Measurements using the KLOE-2 apparatus equipped with the inner tracker, new scintillation calorimeters and tagging detectors for gamma-gamma physics will allow to refine and extend the KLOE program on kaon physics and tests of fundamental symmetries as well as the quantum interferometry. Here the latest results from KLOE data analysis and perspectives at KLOE-2 are presented.

description: Sterylglycoside (SG) stellen eine wichtige Gruppe von sekundären Pflanzeninhaltsstoffen dar, die vor allem in der Regulation der Fluidität und Permeabilität von Membranen von Bedeutung sind. Hinsichtlich der Varietät und ihrer genauen Funktion besteht jedoch noch Aufklärungsbedarf. Im Rahmen der vorliegenden Arbeit wurde anhand synthetisierter Standards eine selektive LC-MS/MS-Methode (ESI, positiv) zur Bestimmung glycosilierter, steroidaler Strukturen, insbesondere von SGs, in pflanzlichen Proben entwickelt. Mit der neuartigen Methode konnten in ausgewählten Pflanzen glycosilierte Sterole qualitativ und quantitativ bestimmt werden. So wurden in der Aubergine erstmals die bedeutendsten SGs als intakte Strukturen quantifiziert und darüber hinaus neuartige Strukturen identifiziert. Darüber hinaus wurde in ausgewählten Extrakten das 7-Dehydrocholesterol-β-D-Glucosid und das Vitamin D3-β-D-Glucosid nachgewiesen, dessen Synthese durch gezielte UV-Bestrahlung initiiert wurde. Somit könnte die Aubergine als neuartige Quelle für pflanzliches Vitamin D dienen, welches bisher nur in wenigen Pflanzen nachweisbar war.
description: Steryl glycosides (SGs) are a small group of phytochemicals regulating the fluidity and permeability of membranes in plants. About variety and special functions further investigations are necessary. In present work a selective LC-MS/MS-method (ESI, positive) for the determination of glycosylated steroidal structures, especially steryl glycosides (SGs) in various plants was developed based on synthesized glycosylated sterols as surrogates. The developed method enabled separation and determination of glycosylated sterols in selected plants in a qualitative and quantitative manner. In consequence the most important SGs were determinated in eggplants as intact structures for the first time and new structures were identified. Furthermore in some special extracts 7-dehydrocholesterol-β-D-glucoside and vitamin D3-β-D-glucoside were found. The synthesis of these structures was induced by ultraviolet irradiation with various intensities. Consequently eggplants could be a unique source for plant based vitamin D that was determined in only a few inedible plants until now.

description: We derive a set of equations that describe the shape and behaviour of a single perturbed vortex line in a Bose-Einstein condensate. Through the use of a matched asymptotic expansion and a unique coordinate transform a relation for a vortex's velocity, anywhere along the line, is found in terms of the trapping, rotation, and distortion of the line at that location. This relation is then used to find a set of differential equations that give the line's specific shape and motion. This work corrects a previous similar derivation by Anatoly A. Svidzinsky and Alexander L. Fetter [Phys. Rev. A \textbf{62}, 063617 (2000)], and enables a comparison with recent numerical results.

description: This brief provides a blueprint for state and local policymakers, early learning administrators, teachers, families, community leaders, and researchers to use effective preschool curricula and teaching strategies to help low-income young children close the achievement gap in early literacy and math to be ready for kindergarten like their more affluent peers. It is part of a series of publications from the Pathways to Early School Success project of NCCP that addresses the question: "What will it take to ensure that young low-income children succeed in the early school years?" The brief and the more in-depth report—Effective Preschool Curricula and Teaching Strategies—are both based on a meeting that NCCP convened bringing together distinguished researchers, as well as a careful review of recently funded research. Other issue briefs in the Pathways project have focused on the importance of strategies to promote social and emotional competence in infants, toddlers and preschoolers: Helping the Most Vulnerable Infants, Toddlers, and Their Families, and Resources to Promote Social and Emotional Health and School Readiness in Young Children and Families—A Community Guide

description: Over the past decade, considerable public and private attention has been focused on strengthening strategies for early childhood development and family support. States are steadily increasing support for child development, child care, and family support programs targeting young children and families, and initiatives focused on cities are growing. Advocates have promoted broad community mobilization and public awareness about the importance of early childhood. For the most part, however, activity to promote healthy child development and provide support to families with young children has not been linked with efforts to promote family economic security in low-income communities. At the same time, initiatives to promote community building and address economic issues in low-income communities have typically not explicitly addressed the developmental and family support needs of young children and families. Recognizing this, the National Center for Children in Poverty (NCCP) decided to undertake an exploratory project to see what community-based organizations in low-income communities and neighborhoods are doing to promote the healthy development of low-income young children and families through child development and family support strategies. Our original aim was to include Comprehensive Community Initiatives as well as Empowerment Zones in our effort. However, at the time the project began, Comprehensive Community Initiatives did not generally address issues facing young children, and the Empowerment Zones generally focused only on child care.3 Therefore, NCCP chose to focus on community development corporations, or CDCs. CDCs are, in effect, the "bread and butter" of community building. Typically, CDCs work to promote community leadership and economic development. In viewing CDCs through a young child and family lens, the hope was that this study would identify approaches that could be nurtured and grown. Absent that, the hope was to learn what else might be done to capitalize on the strengths of CDCs in promoting improved outcomes to young children.
