Dirac Lepton Angle Matrix v.s. Majorana Lepton Angle Matrix and Their Renormalization Group Running Behaviours

description: Enlightened by the idea of the 3 times 3 CKM angle matrix proposed recently by Harrison et al., we introduce the Dirac angle matrix Phi and the Majorana angle matrix Psi in the lepton sector for Dirac and Majorana neutrinos respectively. We show that in presence of the CP violation, the angle matrix Phi or Psi is entirely equivalent to the complex MNS matrix V itself, but has the advantage of being real, phase rephasing invariant, directly associated to the leptonic unitarity triangles (UTs) and do not depend on any particular parametrization of V. In this paper, we further analyzed how the angle matrices evolve with the energy scale. The one-loop Renormalization Group Equations (RGEs) of Phi, Psi and some other rephasing invariant parameters are derived and the numerical analysis is performed to compare between the case of Dirac and Majorana neutrinos. Different neutrino mass spectra are taken into account in our calculation. We find that apparently different from the case of Dirac neutrinos, for Majorana neutrinos the RG-evolutions of Phi, Psi and the Jarlskog strongly depend on the Majorana-type CP-violating parameters and are quite sensitive to the sign of Delta m^{2}_{31}. They may receive significant radiative corrections in the MSSM if three neutrino masses are nearly degenerate.

description: Early childhood is a time of great opportunity. State policymakers recognize this and some are trying to use resources strategically to promote healthy development and school readiness in young children. This report, based on findings from NCCP's Improving the Odds for Young Children project, highlights key findings from NCCP's database of state policy choices that provides a unique picture of early childhood policies across the states. The report summarizes emerging patterns and can be used to stimulate a dialogue, both within the states and nationally, about how to make more strategic, coherent investments in young children.
Kaliumfreisetzung im Serum während nicht-ischämischer Unterarmbelastung bei Patienten mit distalen neurogenen Paresen
Creators: name: Göbel, Susanne Andrea

Subjects: subject: 610

description: Diese Arbeit geht der Frage nach ob bei neurogenen Paresen ein erhöhter spezifischer Kaliumanstieg zu messen ist, wie es bei myogenen Paresen der Fall ist. Ebenso soll die Kaliumfreisetzung bei unterschiedlichen Kraftgraden untersucht werden. Die Maximalkraft der Patienten war signifikant niedriger als in der Kontrollgruppe. Im Verlauf eines Durchgangs stellte sich ein Gleichgewicht des Kaliums ein, das innerhalb der drei Minuten konstant blieb. Dies fand sich in beiden Gruppen gleichermaßen. Der absolute Kaliumanstieg war in der Kontrollgruppe signifikant höher. Im Gegensatz zu vorherigen Studien bei myogenen Paresen konnte kein erhöhter spez. Kaliumanstieg bei neurogenen Paresen nachgewiesen werden. Während sich bei der Kontrollgruppe ein signifikanter Abfall des spez. Kaliumanstiegs zwischen den einzelnen Durchläufen mit verschiedenen Kraftgraden zeigte, konnte man bei den Patienten einen Anstieg beobachten. Die Unterschiede beim spez. Kaliumanstieg zwischen Gesunden und neurogenen Paresen könnten durch das unterschiedliche Rekrutierungsverhalten oder die Entladungsfrequenz einzelner motorischer Einheiten verursacht sein.
description: This study examined the question of whether you can find an increased specific potassium in neurogenic pareses, as you did in myopathic. Furthermore it was tested how the potassium release changes during different levels of exercise. The maximal contraction force of the patients was significantly below the ones of the healthy test persons. During the three minutes of a test run a stable equilibrium is set up. This result could be shown in both test groups. The absolute increase of the potassium concentration was significantly higher within the healthy test group compared to the patients. If you compare the three test runs within one test group, you can see a significant decrease of the specific potassium in the healthy test persons. In contrast to that the patient group shows an increase from the weaker to the stronger levels of exercise. The differences of the specific potassium in the both test groups could be based on the different recruitment behaviours or frequencies of discharge in single motor units of both test groups.

description: For the last 2 years, Florida State University Libraries' Technology and Digital Scholarship department has been exploring ways to incorporate 3D model data into DigiNole, FSU's digital repository built on the open source Islandora 7 platform. In August 2023 we finally reached a major milestone with a publicly viewable demo open for review and testing by internal stakeholders. This represents the culmination of much collaborative work between 3D modeling subject experts and developers, and a lot of hard lessons learned along the way that we are ready to share with others trodding a similar path. Join us for a summary of our journey into the unfamiliar realm of 3D modeling, and learn how you can extend your IR to handle 3D model data as well! This session covers the specific requirements for supporting 3D model data as scholarly research outputs stored in an institutional repository, and is aimed at an audience familiar with standard scholarly content in an institutional repository but with little to no prior knowledge of 3D modeling. Topics covered will include the production and use of scholarly 3D model data by students and faculty, unique metadata elements for 3D model data, how to create a 3D model test suite, tips for integrating a 3D model viewer like the Online 3D Viewer (https://3dviewer.net/) into your repository, an overview of the most popular 3D model file formats, and a discussion about the complexities of building a system that creates a consistent user experience for ingesting and displaying 3D models with surprisingly inconsistent data structures.

description: Building on previous analyses that revealed a significant level of absenteeism in the early school years, especially among low-income children, and confirmed its detrimental effects on school success, this second report in this series explores how maternal and family risks impact early school absenteeism. Using data from a nationally representative sample of kindergartners from across various incomes and race/ethnicity groups – the Early Childhood Longitudinal Study (Kindergarten Cohort)7, NCCP examines the prevalence of risk factors known to threaten young children’s healthy development and early school success. These include: poverty, teenage and/or single parenting, low levels of maternal education, receipt of welfare, unemployment, poor maternal health, food insecurity, and large family size – that is, four or more children at home. It also assesses the cumulative impact of early exposure to multiple risk factors, building on a large body of research showing that the more demographic and psycho-social risks children encounter, the more likely they are to experience poor developmental and school outcomes.

We show that the von Neumann and Renyi entanglement entropies grow asymptotically as N^(1-1/d) ln N, with a prefactor that is analytically computed using the Widom conjecture both for periodic and open boundary conditions. The logarithmic correction to the power-law behavior is related to the area-law violation in lattice free fermions. These asymptotic large-N behaviors are checked against exact numerical calculations for N-particle systems.

description: We present a systematic study of the dijet suppression at RHIC using the VNI/BMS parton cascade. We examine the modification of the dijet asymmetry A_j and the within-cone transverse energy distribution (jet-shape) along with partonic fragmentation distributions z and j_t in terms of: qhat; the path length of leading and sub-leading jets; cuts on the jet energy distributions; jet cone angle and the jet-medium interaction mechanism. We find that A_j is most sensitive to qhat and relatively insensitive to the nature of the jet-medium interaction mechanism. The jet profile is dominated by qhat and the nature of the interaction mechanism. The partonic fragmentation distributions clearly show the jet modification and differentiate between elastic and radiative+elastic modes.

description: As part of our initiative, "Promoting Tolerance and Respect for Diversity in Early Childhood: Toward A Research and Practice Agenda," the National Center for Children in Poverty (NCCP) attempted to map the nature of U.S. approaches to diversity, tolerance, and respect for diversity (DTRD) education in programs directed to children from birth to ten years of age, in order to identify: current DTRD curricula used in early childhood education and other initiatives; common components across initiatives; evaluation designs and methodologies; and barriers and opportunities related to implementation, as well as potential levers for taking DTRD education to scale. Approximately 40 organizations implementing DTRD programs with children from birth to 10 years of age, and/or their parents, teachers or caregivers were identified through internet searches, recommendations, or the literature. The foregoing pages present a summary of the main points discussed with representatives from ten organizations, followed by descriptive profiles of all the organizations identified.

description: We study ~330 massive (M* > 10^9.5 MSun), newborn spheroidal galaxies (SGs) around the epoch of peak star formation (1 10^10.5 MSun, and an age trend becomes evident in this mass regime: SGs with M* > 10^11.5 MSun are ~2 Gyrs older than their counterparts with M* < 10^10.5 MSun. Nevertheless, a smooth downsizing trend with galaxy mass is not observed, and the large scatter in starburst ages indicate that SGs are not a particularly coeval population. Around half of the blue SGs appear not to drive their star formation via major mergers, and those that have experienced a recent major merger, show only modest enhancements (~40%) in their specific star formation rates. Our empirical study indicates that processes other than major mergers (e.g. violent disk instability driven by cold streams and/or minor mergers) likely play a dominant role in building SGs, and creating a significant fraction of the old stellar populations that dominate today's Universe.

description: Besides parametric uncertainties and disturbances, the unmodeled dynamics and time delay at the input are often present in practical systems, which cannot be ignored in some cases. This paper aims to solve output feedback tracking control problem for a class of nonlinear uncertain systems subject to unmodeled high-frequency gains and time delay at the input. By the additive decomposition, the uncertain system is transformed to an uncertainty-free system, where the uncertainties, disturbance and effect of unmodeled dynamics plus time delay are lumped into a new disturbance at the output. Sequently, additive decomposition is used to decompose the transformed system, which simplifies the tracking controller design. To demonstrate the effectiveness, the proposed control scheme is applied to three benchmark examples.

description: The reproductive and sexual health needs of adolescents differ from those of adults. During adolescence, the body undergoes significant developmental changes, most notably puberty, the bodily changes of sexual maturation, and the formation of sexual identity. Achieving reproductive and sexual health requires more than preventing unwanted pregnancy and sexually transmitted infections, it includes developing the ability to form and maintain meaningful relationships with others and with one's own body. Psychological, social, educational, environmental, and economic factors, among others, all play a role. In addition, adolescents are more likely to engage in risk-taking behaviors than either younger children or adults. These significant factors underline the importance of meeting the reproductive and sexual health needs of this age group. Reproductive and sexual health — combined with mental health disorders and emotional problems, violence and unintentional injury, substance use, and poor nutrition — form part of a complex web of potential challenges to adolescents' healthy emotional and physical development.
Sociality in cobweb spiders (Anelosimus spp.) : evolutionary consequences and the role of pre-existing traits
Creators: name: Samuk, Kieran Mikhail
Publisher: name: University of British Columbia
Year: 2011

description: Sociality – cooperative group living – is ubiquitous in the natural world, yet our understanding of its evolution is still in its infancy. In this thesis, I explore two poorly understood aspects of the evolutionary origin and consequences of sociality using social cobweb spiders (Anelosimus spp.) as a model system. First, I examine how pre-exisiting traits have contributed to the evolution of alloparental care – the care of non-descendant offspring – in social cobweb spiders. I begin by showing alloparental care is extensive in wild social cobweb spider nests. I then test the hypothesis that alloparental care occurs as a result of a lack of discrimination against foreign egg sacs. In support of this hypothesis, I show that subsocial species from clades sister to the social species freely care for foreign egg sacs. This suggests that a lack of offspring discrimination is ancestral to sociality in cobweb spiders and alloparental care likely emerged spontaneously along with group living. This may have facilitated the evolution of sociality by immediately providing the group-level benefits of alloparental care. Secondly, I examine how social life may have altered natural selection acting on social cobweb spiders. In social cobweb spider nests, the protection offered by a communal nest and the presence of alloparents may have relaxed natural selection on individual maternal care behaviour. Using a comparative approach, I test the hypothesis that sociality is associated with reduced maternal care behavioural phenotypes. I show that social species from independently derived social clades score significantly lower than their subsocial sister taxa on six different assays of maternal care, including the probability of repairing damaged egg sacs and of abandoning egg sacs in the face of simulated predation. Integrating a number of supporting facts, I interpret this result as suggestive of relaxed natural selection on maternal care behaviour as a consequence of sociality. Together, the two comparative studies I present reveal a key role for pre-existing traits in the origin of sociality and that the forces of evolution are likely altered in concert with the onset of social life.
The Fermion Mass Hierarchy in Models with Warped Extra Dimensions and a Bulk Higgs

description: The phenomenological implications of allowing the Higgs to propagate in both AdS${}_5$ and a class of asymptotically AdS spaces are considered. Without tuning, the vacuum expectation value (VEV) of the Higgs is peaked towards the IR tip of the space and hence such a scenario still offers a potential resolution to the gauge-hierarchy problem. When the exponent of the Higgs VEV is approximately two and one assumes order one Yukawa couplings, then the fermion Dirac mass term is found to range from $\sim 10^{-5}$ eV to $\sim 200$ GeV in approximate agreement with the observed fermion masses. However, this result is sensitive to the exponent of the Higgs VEV, which is a free parameter. This paper offers a number of phenomenological and theoretical motivations for considering an exponent of two to be the optimal value. In particular, the exponent is bounded from below by the Breitenlohner-Freedman bound and the requirement that the dual theory resolves the gauge hierarchy problem. While, in the model considered, if the exponent is too large, electroweak symmetry may not be broken. In addition, the holographic method is used to demonstrate, in generality, that the flatter the Higgs VEV, the smaller the contribution to the electroweak $T$ parameter. In addition, the constraints from a large class of gauge mediated and scalar mediated flavour changing neutral currents, will be at minimal values for flatter Higgs VEVs. Some initial steps are taken to investigate the physical scalar degrees of freedom that arise from a mixing between the $W_5/Z_5$ components and the Higgs components.

description: Active duty military personnel and National Guard and reservists experience multiple deployments as a result of the conflicts that comprise the War on Terror. A large body of research has accumulated on the behavioral health problems faced by military personnel as a result of these conflicts. After nearly a decade of war, a growing area of research shows the negative impact on children, youth and families of U.S. military personnel. Children of military families often experience multiple stressors before and during their parent's deployment and when they come home. Without appropriate mental health support systems, children of military personnel may be at a significant disadvantage compared with their peers in non-military families.

description: It has long been recognized that chronic absenteeism and school truancy in middle and high school are significant problems with highly visible negative consequences for youth, and ultimately, for their employability as adults. Little is known, however, about chronic school absenteeism among early elementary school students, as well as among children in preschool programs. This brief reveals a significant level of absenteeism in the early school years, especially among low-income children, and confirms its detrimental effects on school success by examining children from across various incomes and race/ethnicity groups in a nationally representative sample of children entering kindergarten—The Early Childhood Longitudinal Study (Kindergarten Cohort)—in 1998.

description: Little research examines the experiences of victims of sex trafficking after they have been rescued and only a handful of studies collected primary data from these victims. This qualitative study involved in-person interviews with immigrant sex trafficking victims. Findings reveal that female victims face challenges similar to transnational mothers; they experience separation and their role as mothers is largely focused on self-sacrifice. Findings also suggest that it is important for practitioners to understand that female immigrant sex trafficking victims who are mothers may have a strong commitment to their children that may assist them toward restoration and looking toward the future.

description: This Commentary brings together a body of literature and comparative critical research to pro-pose a description of the problem space of graphic communication. The lack of a canonical description of graphic communication’s function and operation requires the development of a model for the graphic system before descriptive experimental studies can be designed or ethically deployed.The author was a practising designer during the digital revolution in communication design and witnessed disruptive production technologies driving cultural changes. Changes that challenged a mass of graphics doctrines and defined the researcher’s original intent: effectively instructing design students as to why a specific combination of media and symbol was effective for a specified audience. As Scher (1994) would note graphic education ‘theoretics’ but not ‘theoretics as an end in itself.’The research presented is in the form of peer-reviewed publications over a 15-year period representing a single strand of original research into the epistemology and problematics of the graphic communication system in addressing users.

description: Young children's health is essential to their overall development, well-being, and school readiness. Untreated health problems and a lack of preventive care contribute to higher rates of serious illness, absenteeism in preschool, physical and emotional distress, and even long-term disability. At a historic moment when the passage of federal health care reform promises significant improvements in health care access for many Americans, it is important to take stock of how well states are currently meeting the health needs of young children in low-income families. This brief presents information from NCCP's Improving the Odds for Young Children project about state policy choices in the following areas that affect the health and well-being of children, ages birth to 5: access to health care and continuity of care; maternal health care; and preventive screening and assessment. Relevant components of health care reform legislation are considered in a set of recommendations for meeting the short and long-term health care needs of young, low-income children.

description: Sexual assault is a major social problem that requires well-informed, empirically grounded policy and practice responses. This study was conducted to determine the prevalence of sexual assault in Texas and to add to our understanding of the crime of sexual assault. A representative sample of 1,200 adult women and men aged 18 and older from diverse ethnic/racial, socioeconomic, and educational backgrounds was interviewed about their lifetime experiences of sexual assault victimization. Approximately 20 percent of women and five percent of men had been sexually assaulted during their lifetimes. Overall, the prevalence was 13 percent. The findings are consistent with research in general population in the US (Elliott, Mok and Briere, 2004) and internationally (World Health Organization, 2005) underscoring the cross-cultural occurrence of adult sexual assault. This information can assist social workers to target support services to victims and to develop innovative services and policy recommendations for sexual assault survivors.

In order to study how the \textquotedblleft constants\textquotedblright\ $G$ and $Λ$ may vary, we propose three scenarios where such constants are considered as time functions. The first model is a perfect fluid. We find that the behavior of $G$ and $Λ$ are related. If $G$ behaves as a growing time function then $Λ$ is a positive decreasing time function but if $G$ is decreasing then $Λ$ is negative. For this model we have found a new solution. The second model is a scalar field, where in a phenomenological way, we consider a modification of the Klein-Gordon equation in order to take into account the variation of $G$. Our third scenario is a scalar-tensor model. We find three solutions for this models where $G$ is growing, constant or decreasing and $Λ$ is a positive decreasing function or vanishes. We put special emphasis on calculating the curvature invariants in order to see if the solutions isotropize.

Making Work Supports Work: A Picture of Low-wage Workers in America

description: Many full-time workers in the United States are unable to make ends meet. Government "work support" policies — benefit programs such as earned income tax credits, public health insurance, child care assistance, and SNAP/food stamps — can help some families close the gap between low earnings and the high cost of basic expenses. While federal government guidelines provide a framework for work support policies in the United States, there is wide variation in how these policies are implemented across states. This report analyzes the effectiveness of these policies. Findings from this report show that the current patchwork of state policies fails to ensure that workers are able to afford their families' basic living expenses, leaving a number of low-wage workers and their families without adequate support. A greater federal investment is needed to create a comprehensive work support system that is designed to encourage and reward employment as well as provide workers with enough resources to care for their families. Federal priorities should include addressing the high cost of basic needs with an increased investment in affordable child care, subsidized health insurance, and housing assistance as well as structuring the work support system to better support workers' advancement toward financial self-sufficiency.
Could a light Higgs boson illuminate the dark sector?

description: The impact a new neutral light particle of spin 0, 1/2, 1, or 3/2 could have on the tiny width of a light Higgs boson is systematically analyzed. To this end, we include all the relevant effective interactions, whether renormalizable or not, and review the possible signatures in the Higgs decay modes with missing energy. This includes the fully invisible Higgs boson decay, as well as modes with SM gauge boson or fermions in the final state. In many cases, simply preventing these modes from being dominant suffices to set tight model-independent constraints on the masses and couplings of the new light states.

description: This study explores the underlyingstructure of the perceptions of 1,342 men arrested for tryingto hire a prostituted woman on the street. The analysis identified eight structural dimensions that accounted for 47% of the explained variance. Three factors contained items reflectingpatriarchal views of women and perceived entitlement to power and control, which are issues that could lead men to exhibit violence. Findings suggest that lower levels of education, conservative attitudes toward sexuality, more frequent pornography use, and traumatic life experiences may be related to entitlement to power and control factors, which in turn could be used to justify violence against women
Rawlsian Justice: Reflections on a new Equilibrium

Subjects: subject: Ethics, intergenerational Justice, Intergenerational Rights and Duties, Rawls's Theory of Justice
subject: Education--Philosophy of

description: This thesis considers the notion of intergenerational justice. I consider intertemporal justice largely through the lens of John Rawls’s theory of justice. Nonetheless, Rawls incorrectly gives priority to the principle of reciprocity in his theory. I correct Rawls’s misunderstanding concerning reciprocity. I also discuss the often-overlooked importance of natural duties to Rawls’s theory. I add the condition of vulnerability to Rawls’s circumstances of justice. By making these changes I (a) give priority to impartiality in Rawls’s theory, (b) remove the difficulties created by Rawls’s present-time-of-entry interpretation, (c) remove the need for Rawls’s motivational assumption, and (d) remove the chance-timing of a person’s birth as an arbitrary contingency and basis for bias in the decision-making of those behind the veil of ignorance.
Constellations and multicontinued fractions: application to Eulerian triangulations

description: We consider the problem of enumerating planar constellations with two points at a prescribed distance. Our approach relies on a combinatorial correspondence between this family of constellations and the simpler family of rooted constellations, which we may formulate algebraically in terms of multicontinued fractions and generalized Hankel determinants. As an application, we provide a combinatorial derivation of the generating function of Eulerian triangulations with two points at a prescribed distance.

description: A recent and compelling study entitled Neurons to Neighborhoods, conducted by the Board on Children, Youth, and Families of the Institute of Medicine, calls attention to the importance of early emotional development in young children. Based on a careful review of neuroscience and developmental science, it highlights compelling evidence that a child's earliest experiences and relationships set the stage for how a child manages feelings and impulses, and relates to others. It also highlights emerging and perhaps surprising evidence that emotional development and academic learning are far more closely intertwined in the early years than has been previously understood. This policy paper focuses on what emerging research tells policymakers about why it is so important to intervene to help young children at risk for poor social, emotional, and behavioral development and what kinds of research-based interventions seem most effective.

Due to recent progress on the numerical side we are able to present results for the generalized form factors at pion masses as low as 260 MeV. We perform a fit to one-loop covariant baryon chiral perturbation theory with encouraging results.

description: Despite the national decline in child poverty and low-income rates in the United States since the early 1990s, the rates in California have surpassed those of the nation. This demographic profile of California's low-income families highlights the high number and rate of low-income children in California. It also features several facts that challenge stereotypes about these families. For example, a large and growing majority of poor children live in working families, and as many of California's poor children live in two-parent as in single-parent families. This report illustrates the rapidly changing demographic picture of California's poor and low-income families. Almost half of all California's children are immigrants, and the large majority of these immigrants are Hispanic. The high poverty rates among these children require urgent attention in order to promote the healthy growth and development of this large and expanding part of California's next generation.
