Cyclic, f-Cyclic, and Bicyclic Decompositions of the Complete Graph into the 4-Cycle with a Pendant Edge.

In this paper, we consider decompositions of the complete graph on v vertices into 4-cycles with a pendant edge. In part, we will consider decompositions which admit automorphisms consisting of: (1) a single cycle of length v, (2) f fixed points and a cycle of length v − f, or (3) two disjoint cycles. The purpose of this thesis is to give necessary and sufficient conditions for the existence of cyclic, f-cyclic, and bicyclic Q-decompositions of Kv

\u3ci\u3e Chenopodium berlandieri \u3c/i\u3e and the Cultural Origins of Agriculture in the Eastern Woodlands

The development of agriculture in the New World has been a topic of prominent historic interest, but one that has ignored some regions in favor of others. The woodlands of Eastern North America have felt this bias in the investigation of agricultural origins, but this has not prevented the development of theories to explain the emergence of a complex of indigenous agricultural plants in the region. Data collection and technological advances have in large part validated these theories, creating a model for domestication. By emphasizing farming over other cultural practices, however, these theories lack explanatory power with regards to the domestication of some plants indigenous to the region, such as Chenopodium berlandieri Moq. As one of the predominant plants of the Eastern Agricultural Complex, investigation of Chenopodium berlandieri supports alternative possibilities for plant use and adoption, in addition to or separate from agriculture. Based on ethnographic and archaeological evidence, it seems likely that alternative aspects of this plant were a driving force in both its initial use and its continued cultural value to the peoples of the Eastern Woodlands. Weedy plants, such as those utilized in Eastern North America, have a special relationship with human populations. That these same plants have a high proportion of active chemical compounds that are useful for medicine and food preservation suggests that a reevaluation of traditional perspectives of agricultural development is necessary. Any holistic understanding of plant use in the Eastern Woodlands should consider all possible cultural values in considering the nature of human-plant interaction

Developing a targeted English-language curriculum and materials for Latino caregivers of infants with special needs as part of a NICU pre-discharge education program

poster abstractAbstract: Latino infants with special healthcare needs are at high risk of mortality and have difficulty obtaining specialty care. Poor English-language skills of the caregivers add an additional layer of vulnerability. Existing health-related English-language programs address adult, but not pediatric health concerns. A clear need exists for short-term health-related English-language education programs to develop survival communication skills in low-literacy Limited English Proficiency (LEP) caregivers. To fill this need for intervention, the International Center for Intercultural Communication (ICIC) at IUPUI collaborated with Family Voices Indiana, a family advocacy group, and created a grant-funded series of classes to be taught in a one-on-one setting at Riley Hospital for Latino LEP parents of Neonatal Intensive Care Unit (NICU) babies. The goal of the study is to provide these parents with the English language competency to take an active part in the medical decision making and care of their children. An additional goal of the program is to improve families' ability to enroll in local English as Second Language programs in the community. The findings will be discussed in three parts: We will first feature the needs-analysis period followed by the development of a curriculum, instructional materials, and pre-post intervention assessments based on the identified needs. Second, we will feature the actual intervention and will involve cases from working with low-literacy/low-proficiency caregivers. Third, we will discuss the post-intervention stage and feature data analysis with the purpose of assessing the viability of the curriculum and materials that would lead to revisions. The project is designed to ensure eventual adaptability of the curriculum for ESL caregivers of various language backgrounds, stronger language or literacy skills, a variety of healthcare contexts, and the larger pediatric population

Duality Symmetric Strings, Dilatons and O(d,d) Effective Actions

We calculate the background field equations for the T-duality symmetric string building on previous work by including the effect of the Dilaton up to two-loops. Inclusion of the Dilaton allows us to obtain the full beta functionals of the duality symmetric sigma model. We are able to interpret the result in terms of a dimensionally reduced O(d,d) invariant target space effective action.Comment: 15 pages, latex; v2 reference added, typos fixe

Background Field Equations for the Duality Symmetric String

This paper describes the background field equations for strings in T-duality symmetric formalisms in which the dimension of target space is doubled and the sigma model supplemented with constraints. These are calculated by demanding the vanishing of the beta-functional of the sigma model couplings in the doubled target space. We demonstrate the equivalence with the background field equations of the standard string sigma model.Comment: 26 pages, latex, v2 typos correcte

Check-Cases for Verification of 6-Degree-of-Freedom Flight Vehicle Simulations

This NASA Engineering and Safety Center (NESC) assessment was established to develop a set of time histories for the flight behavior of increasingly complex example aerospacecraft that could be used to partially validate various simulation frameworks. The assessment was conducted by representatives from several NASA Centers and an open-source simulation project. This document contains details on models, implementation, and results

Scalability of Hydrodynamic Simulations

Many hydrodynamic processes can be studied in a way that is scalable over a vastly relevant physical parameter space. We systematically examine this scalability, which has so far only briefly discussed in astrophysical literature. We show how the scalability is limited by various constraints imposed by physical processes and initial conditions. Using supernova remnants in different environments and evolutionary phases as application examples, we demonstrate the use of the scaling as a powerful tool to explore the interdependence among relevant parameters, based on a minimum set of simulations. In particular, we devise a scaling scheme that can be used to adaptively generate numerous seed remnants and plant them into 3D hydrodynamic simulations of the supernova-dominated interstellar medium.Comment: 12 pages, 1 figure, submitted to MNRAS; comments are welcom
