Probing eccentric higher order modes through effective chirp mass model

The three observational runs of advanced LIGO and Virgo detectors have detected ~90 compact binary coalescence events with most of them being quasi-circular compact binary merger events. Astrophysical models predict compact binary mergers with appreciable non-zero eccentricity if in dense stellar environments like globular clusters, AGN discs. Gravitational wave searches from eccentric systems are either limited to very low eccentricities or rely on model-agnostic time-frequency-based searches. Typically, gravitational waves from eccentric systems with moderate eccentricities carry non-negligible energy in the eccentric higher order modes. In this work, using the effective chirp mass model developed using EccentricTD waveform, we develop a phenomenological scaling relation for the eccentric higher order mode time-frequency track. Further, we incorporate this additional information from the higher order eccentric mode for non-spinning, stellar mass eccentric binaries to improve the constraint on eccentricity.Comment: 10 pages, 4 figure

From Test to Testimony: Resiliency After a TBI Diagnosis

Autoethnographic research is a relatively new means of gathering data on oneself to connect to research and theory while advocating for change within a policy, law, and/ or environment. In this autoethnography I will recount the experience of my traumatic brain injury (TBI) diagnosis following a car accident and present a few implications for the professionals and members of the society at large surrounding the issue of TBI such as the need for awareness and understanding as well as the importance of therapy and other forms of care within different cultures. When I was first diagnosed, many people did not know what TBI was, what it stood for, or what symptoms could result. Although research has progressed with this diagnosis, there is still a long road ahead. The first step to change is recognizing that there is a problem. After the problem is recognized, the solution can begin

Nutrition Education Resources in North Carolina–Based Head Start Preschool Programs: Administrator and Teacher Perceptions of Availability and Use

Objective: The purpose of this study was to provide new insight into common barriers to the availability and use of nutrition education (NE) resources in Head Start preschool programs based on administrator and teacher perceptions. Methods: In-depth, semistructured phone interviews (n = 63) were conducted with administrators (n = 31) and teachers (n = 32) from North Carolina–based Head Start programs. Interviews were audio-recorded and transcribed verbatim. Data were analyzed qualitatively using content analysis to identify common themes. Results: Five emergent themes were identified within the areas of NE resource availability and use and barriers to NE resource availability and use. Participants expressed desire for greater organization of existing NE material resources, increased community support, and professional development opportunities for teachers specific to NE. Funding and time constraints were reported as affecting NE resources. Conclusions and Implications: Creative strategies for addressing NE resource availability and use and barriers (e.g., NE integration with educational standards) in Head Start are needed

Comparison of Parent and Child Ratings of Fruit and Vegetable Liking to Assess Parent Accuracy as Proxy Reporters

This study examined the accuracy of parent-report child fruit/ vegetable (FV) liking. Child/parent dyads (n = 24) were recruited from six Head Start preschools in North Carolina. Liking for 10 FVs was assessed using a validated pictorial tool for children; a similar scale was used for parents. Negative relationships were observed between parent/child for one fruit (grapes) and one vegetable (broccoli). Positive relationships were observed among oranges, grapes, and overall fruit rankings. Parents tended to rank children’s liking of fruits higher than their children, while children ranked liking vegetables higher. Findings suggest parents may not be accurate respondents for preschool children’s FV liking

Eating Smart and Moving More for Head Start: A Pilot Study

Our study examined the relationship between improved personal health behaviors of Head Start teachers’ and the promotion of positive health behaviors in their classroom. Thirty-three Head Start teachers across 7 centers received six 30-minute nutrition education lessons. Dietary intake, physical activity, and self-efficacy for promoting positive health behaviors in the classroom were measured at baseline and post-intervention. Significant improvements were observed for dietary intake and physical activity. Self-efficacy for promoting health behaviors in the classroom did not significantly improve. Additional education is needed to improve health promotion practices. Lessons learned contributed to program refinement. Implications for Extension are discussed

Integrated Photonic Platforms for Quantum Technology: A Review

Quantum information processing has conceptually changed the way we process and transmit information. Quantum physics, which explains the strange behaviour of matter at the microscopic dimensions, has matured into a quantum technology that can harness this strange behaviour for technological applications with far-reaching consequences, which uses quantum bits (qubits) for information processing. Experiments suggest that photons are the most successful candidates for realising qubits, which indicates that integrated photonic platforms will play a crucial role in realising quantum technology. This paper surveys the various photonic platforms based on different materials for quantum information processing. The future of this technology depends on the successful materials that can be used to universally realise quantum devices, similar to silicon, which shaped the industry towards the end of the last century. Though a prediction is implausible at this point, we provide an overview of the current status of research on the platforms based on various materials.Comment: 48 pages, 3 figure

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
