Orbital Stability of Multi-Planet Systems: Behavior at High Masses

In the coming years, high contrast imaging surveys are expected to reveal the characteristics of the population of wide-orbit, massive, exoplanets. To date, a handful of wide planetary mass companions are known, but only one such multi-planet system has been discovered: HR8799. For low mass planetary systems, multi-planet interactions play an important role in setting system architecture. In this paper, we explore the stability of these high mass, multi-planet systems. While empirical relationships exist that predict how system stability scales with planet spacing at low masses, we show that extrapolating to super-Jupiter masses can lead to up to an order of magnitude overestimate of stability for massive, tightly packed systems. We show that at both low and high planet masses, overlapping mean motion resonances trigger chaotic orbital evolution, which leads to system instability. We attribute some of the difference in behavior as a function of mass to the increasing importance of second order resonances at high planet-star mass ratios. We use our tailored high mass planet results to estimate the maximum number of planets that might reside in double component debris disk systems, whose gaps may indicate the presence of massive bodies.Comment: Accepted to Ap

Addressing gender-based violence in the Latin American and Caribbean Region : A critical review of interventions

The authors present an overview of gender-based violence (GBV) in Latin America, with special emphasis on good practice interventions to prevent GBV or offer services to its survivors or perpetrators. Intimate partner violence and sexual coercion are the most common forms of GBV, and these are the types of GBV that they analyze. GBV has serious consequences for women's health and well-being, ranging from fatal outcomes, such as homicide, suicide, and AIDS-related deaths, to nonfatal outcomes, such as physical injuries, chronic pain syndrome, gastrointestinal disorders, complications during pregnancy, miscarriage, and low birth-weight of children. GBV also poses significant costs for the economies of developing countries, including lower worker productivity and incomes, and lower rates of accumulation of human and social capital. The authors examine good practice approaches in justice, health, education, and multisectoral approaches. In each sector, they identify good practices for: (1) law and policies; (2) institutional reforms; (3) community-level interventions; and (4) individual behavior change strategies.Health Monitoring&Evaluation,Gender and Development,Gender and Social Development,Public Health Promotion,Children and Youth,Adolescent Health,Health Monitoring&Evaluation,Youth and Governance,Gender and Social Development,Children and Youth

Moduli of Tropical Plane Curves

We study the moduli space of metric graphs that arise from tropical plane curves. There are far fewer such graphs than tropicalizations of classical plane curves. For fixed genus $g$, our moduli space is a stacky fan whose cones are indexed by regular unimodular triangulations of Newton polygons with $g$ interior lattice points. It has dimension $2g+1$ unless $g \leq 3$ or $g = 7$. We compute these spaces explicitly for $g \leq 5$.Comment: 31 pages, 25 figure

Preventing and responding to gender-based violence in middle and low-income countries : a global review and analysis

Worldwide, patterns of violence against women differ markedly from violence against men. For example, women are more likely than men to be sexually assaulted or killed by someone they know. The United Nations has defined violence against women as"gender-based"violence, to acknowledge that such violence is rooted in gender inequality and is often tolerated and condoned by laws, institutions, and community norms. Violence against women is not only a profound violation of human rights, but also a costly impediment to a country's national development. While gender-based violence occurs in many forms throughout the life cycle, this review focuses on two of the most common types-physical intimate partner violence and sexual violence by any perpetrator. Unfortunately, the knowledge base about effective initiatives to prevent and respond to gender-based violence is relatively limited. Few approaches have been rigorously evaluated, even in high-income countries. And such evaluations involve numerous methodological challenges. Nonetheless, the authors review what is known about more and less effective-or at least promising-approaches to prevent and respond to gender-based violence. They present definitions, recent statistics, health consequences, costs, and risk factors of gender-based violence. The authors analyze good practice initiatives in the justice, health, and education sectors, as well as multisectoral approaches. For each of these sectors, they examine initiatives that have addressed laws and policies, institutional reforms, community mobilization, and individual behavior change strategies. Finally, the authors identify priorities for future research and action, including funding research on the health and socioeconomic costs of violence against women, encouraging science-based program evaluations, disseminating evaluation results across countries, promoting investment in effective prevention and treatment initiatives, and encouraging public-private partnerships.

Foundations in Wisconsin: A Directory [27th ed. 2008]

The 2008 release of Foundations in Wisconsin marks the 27th edition of the print directory and the 8th year of the online version (www.wifoundations.org). The directory is designed as a research tool for grantseekers interested in locating information on private, corporate, and community foundations registered in Wisconsin. Each entry in this new edition has been updated or reviewed to provide the most current information available. Most of the data was drawn from IRS 990-PF tax returns filed by the foundations. However, additional information was obtained from surveys, foundation Web sites, annual reports, and newsletters. Wisconsin foundations have shown continued growth in key areas. The number of active grantmaking foundations has risen to an all-time high of 1,275, with 70 new foundations identified since last year’s publication. While the total grants remained stable at $475 million, the total assets increased by 16.5$7.2 billion.https://epublications.marquette.edu/lib_fiw/1002/thumbnail.jp

First-principles prediction of the information processing capacity of a simple genetic circuit

Given the stochastic nature of gene expression, genetically identical cells exposed to the same environmental inputs will produce different outputs. This heterogeneity has been hypothesized to have consequences for how cells are able to survive in changing environments. Recent work has explored the use of information theory as a framework to understand the accuracy with which cells can ascertain the state of their surroundings. Yet the predictive power of these approaches is limited and has not been rigorously tested using precision measurements. To that end, we generate a minimal model for a simple genetic circuit in which all parameter values for the model come from independently published data sets. We then predict the information processing capacity of the genetic circuit for a suite of biophysical parameters such as protein copy number and protein-DNA affinity. We compare these parameter-free predictions with an experimental determination of protein expression distributions and the resulting information processing capacity of E. coli cells. We find that our minimal model captures the scaling of the cell-to-cell variability in the data and the inferred information processing capacity of our simple genetic circuit up to a systematic deviation
