Universal Three Dimensional Optical Logic

Modern integrated circuits are essentially two-dimensional (2D). Partial three-dimensional (3D) integration and 3D-transistor-level integrated circuits have long been anticipated as routes to improve the performance, cost and size of electronic computing systems. Even as electronics approach fundamental limits however, stubborn challenges in 3D circuits, and innovations in planar technology have delayed the dimensional transition. Optical computing offers potential for new computing approaches, substantially greater performance and would complement technologies in optical interconnects and data storage. Nevertheless, despite some progress, few proposed optical transistors possess essential features required for integration into real computing systems. Here we demonstrate a logic gate based on universal features of nonlinear wave propagation: spatiotemporal instability and collapse. It meets the scaling criteria and enables a 3D, reconfigurable, globally-hyperconnected architecture that may achieve an exponential speed up over conventional platforms. It provides an attractive building block for future optical computers, where its universality should facilitate flexible implementations.Comment: manuscript (5 pages, 3 figures) with supplementary information (6 pages, 5 figures

EnsleyEdits: Creating a Style Resource for Professional Writers

This capstone explores the creation of a resource that helps professional writers keep up with ever-changing style practices and understand the implications of different stylistic and mechanical choices. Examining the history of style guides, analyzing the content of existing style references through the lens of prescriptivism and descriptivism, and assessing the gaps of current online style resources demonstrate how a new online style resource hosted on Instagram, EnsleyEdits, can meet this need for professional writers. Research on current social media, accessibility, and design practices demonstrate how content on the EnsleyEdits account can succeed on Instagram, and the results of an IRB-approved usability study highlight insights from the resource’s target audience. Collectively, these research components reveal how the EnsleyEdits style resource can help writers produce effective, conscious, intentional writing

Professional Preparation Of Secondary Health Education Teachers In Mississippi

The purpose of this study was to examine the professional preparation of secondary health education teachers in Mississippi. All four-year institutions of higher learning were contacted to determine the requirements for an approved program in order to obtain a supplemental endorsement in health, to compare the similarities and differences, and to determine the extent to which the approved programs reflect the ten content areas of the Mississippi Comprehensive Health Framework. This study also examined the status of secondary school health education programs in Mississippi by utilizing selected data from the U.S. Department of Health and Human Services Centers for Disease Control and Prevention 2008 School Health Profiles Study and the 2006 School Health Policies and Programs Study (SHPPS). The findings of this study revealed that eight of Mississippi\u27s four-year institutions offer an approved program for a supplemental endorsement in health. For all eight of these institutions, 12 credit hours are required. Most of these institutions require a semester course in first aid or emergency health care as well as drug abuse, family living, and a methods-of-teaching health course. Only three institutions required or offered as an option a course in human sexuality or sex education. Only one institution required a course on the health benefits of physical activity and only one institution offered as an option a course in nutrition. Upon evaluation of the course content of the eight approved programs to the ten content areas of the Mississippi Comprehensive Health Framework, human growth and development was the content area least covered folloby nutrition. Although the total semester hours required by the approved programs for a health endorsement in Mississippi are well below the semester hours required for an endorsement in other academic areas, the CDC data for Mississippi reported that 87 to 94 percent of the lead health education teachers in Mississippi are certified. According to the CDC data, Mississippi does have specified time requirements for health instruction at the high school level and does provide schools with a curriculum and instructional tools recommended by the CDC

Take Precautions When Feeding Drought-Damaged Corn as Silage

When a corn plant is stunted, or not growing normally, nitrates can build up in the plant. Typically nitrogen that is taken up by the corn plant is converted to amino acids – the building blocks of protein – but in the stressed plant this conversion does not occur. And that’s why producers need to know how to handle and feed drought-damaged corn in silage form, according to Steve Ensley of Iowa State University’s Veterinary Diagnostic and Production Animal Medicine (VDPAM) department
