Hybrid vehicle assessment. Phase 1: Petroleum savings analysis

The results of a comprehensive analysis of near term electric hybrid vehicles are presented, with emphasis on their potential to save significant amounts of petroleum on a national scale in the 1990s. Performance requirements and expected annual usage patterns of these vehicles are first modeled. The projected U.S. fleet composition is estimated, and conceptual hybrid vehicle designs are conceived and analyzed for petroleum use when driven in the expected annual patterns. These petroleum consumption estimates are then compared to similar estimates for projected 1990 conventional vehicles having the same performance and driven in the same patterns. Results are presented in the form of three utility functions and comparisons of sevral conceptual designs are made. The Hybrid Vehicle (HV) design and assessment techniques are discussed and a general method is explained for selecting the optimum energy management strategy for any vehicle mission battery combination. Conclusions and recommendations are presented, and development recommendations are identified

On Optimal Synchronization of Diffusively Coupled Heterogeneous Van der Pol Oscillators

This paper proposes a novel method to achieve and preserve synchronization for a set of connected heterogeneous Van der Pol oscillators. Unlike the state-of-the-art synchronization methods, in which a large coupling gain is applied to couple any pair of connected oscillators, the proposed method first casts the whole synchronization process into two phases. The first one considers the period from the beginning to the first instant of synchronization, while the second phase covers the following time in which synchronization must be preserved. It is shown that a large coupling gain is adopted for the first phase, while the averaged coupling gain to preserve the synchronization in the second phase can be reduced significantly by using an offline optimized coupling law. Efficiency and performance of this method are confirmed by a set of numerical tests with different graphs and system dynamics.Comment: To be published in IFAC World Congress, 202

Lawrence Memorial Hospital and Business Health: A Multi-Tiered Elective Employee Health Opportunity for Lifestyle Intervention

Employer healthcare expenditures are at an all-time high. With these costs greatly impacting the success and growth of small and large businesses, many employers have recognized the potential and positive impact that worksite wellness programs can have on reducing healthcare related costs for their employees. The theory stands that if employees are given the platform, resources, and support from their employer to improve their personal health, it will in turn reduce their risk for developing and maintaining expensive chronic diseases. This project will assess Lawrence Memorial Hospital’s Wellness Program (LMH’s LifeStyle Management Program), propose digital tools that will coincide with their mission, improve doctor-patient communication barriers, and promote positive health changes for all participants. With the thorough research and analysis conducted throughout this project, the objective is to provide LMH with LifeStyle Management Program recommendations and an information technology blueprint that can positively impact the future growth and success of their health initiative.Department of Allied Healt

Exit polling: field research and pedagogical benefits of community engagement

This article explores how bringing students into the research process provides pedagogical benefits for undergraduate students, while also offering faculty original data collection opportunities to further their research agendas. The data described in the article come from an Election Day exit poll fielded by sixty-one students in twelve diverse precincts in Oklahoma City and capture over 1200 voters. Response papers from students demonstrate the educational benefits of involving students in research, which cannot be easily replicated in a traditional classroom environment. Bivariate regression analysis of several 2016 state questions demonstrates the quality and utility of the data collected by students: the analysis shows that voters’ support for reclassifying certain non-violent felonies as misdemeanors is negatively associated with anti-Black racial attitudes; that preferences for lower levels of regulation did not drive support for the so-called alcohol modernization initiative; and that the repeal of the ban on spending public money on religion was not particularly popular—even among the most religiously observant voters in the sample. In total, this article shows that when faculty merge their research agendas with their teaching priorities, they can accrue significant gains in both areas

Expression of prolactin in feline mammary adenomas and adenocarcinomas

Mammary tumors are the third most common tumor in cats after cutaneous neoplasia and lymphosarcoma. More than 80% of feline mammary tumors are adenocarcinomas, which are similar to human mammary adenocarcinomas in their biologic behavior and histologic characteristics. Despite treatment with radical mastectomy, feline mammary adenocarcinoma is associated with a high incidence of metastasis to regional lymph nodes, spleen, liver and lungs. Prolactin (PRL), a protein hormone synthesized by the anterior pituitary gland, stimulates mammary epithelial cell proliferation and differentiation. In many mammalian species, PRL is also produced within the mammary gland. In humans and rodents, PRL is an important mitogen for mammary neoplasia. However, the role of PRL has not been investigated in feline mammary adenomas and adenocarcinomas. The purpose of this study was to determine if feline mammary tumors expressed PRL. Formalin-fixed paraffin-embedded sections of archived mammary tissues (n=6) previously submitted to the Oregon State University Veterinary Diagnostic Laboratory were cut with a width of 6 microns and studied by a modified indirect immunohistochemistry protocol with a polyclonal PRL antibody. Feline anterior pituitary tissue was used to verify the validity of the procedure as PRL expression by lactotrophs in the tissue had positive and specific staining. Prolactin expression was positive and specific in glandular epithelial cells of the mammary gland of some cats (2 of 4) with adenocarcinoma. In conclusion, these results suggest a contribution of PRL in the development of feline mammary neoplasms. Further exploration into the relationship between PRL and feline mammary adenocarcinomas is needed

Bounding an Optimal Search Path with a Game of Cop and Robber on Graphs

Abstract. In search theory, the goal of the Optimal Search Path (OSP) problem is to find a finite length path maximizing the probability that a searcher detects a lost wanderer on a graph. We propose to bound the probability of finding the wanderer in the remaining search time by relaxing the problem into a stochastic game of cop and robber from graph theory. We discuss the validity of this bound and demonstrate its effectiveness on a constraint programming model of the problem. Ex-perimental results show how our novel bound compares favorably to the DMEAN bound from the literature, a state-of-the-art bound based on a relaxation of the OSP into a longest path problem
