XSECT: A computer code for generating fuselage cross sections - user's manual
A computer code, XSECT, has been developed to generate fuselage cross sections from a given area distribution and wing definition. The cross sections are generated to match the wing definition while conforming to the area requirement. An iterative procedure is used to generate each cross section. Fuselage area balancing may be included in this procedure if desired. The code is intended as an aid for engineers who must first design a wing under certain aerodynamic constraints and then design a fuselage for the wing such that the contraints remain satisfied. This report contains the information necessary for accessing and executing the code, which is written in FORTRAN to execute on the Cyber 170 series computers (NOS operating system) and produces graphical output for a Tektronix 4014 CRT. The LRC graphics software is used in combination with the interface between this software and the PLOT 10 software
Advanced communications payload for mobile applications
An advanced satellite payload is proposed for single hop linking of mobile terminals of all classes as well as Very Small Aperture Terminal's (VSAT's). It relies on an intensive use of communications on-board processing and beam hopping for efficient link design to maximize capacity and a large satellite antenna aperture and high satellite transmitter power to minimize the cost of the ground terminals. Intersatellite links are used to improve the link quality and for high capacity relay. Power budgets are presented for links between the satellite and mobile, VSAT, and hub terminals. Defeating the effects of shadowing and fading requires the use of differentially coherent demodulation, concatenated forward error correction coding, and interleaving, all on a single link basis
Electron Transfer-oxy Radical Mechanism for Anti-cancer Agents: 9-anilinoacridines
A possible mode of action involving electron transfer is advanced for the 9- anilinoacridines. The mechanism entails formation of toxic oxy radicals which destroy the neoplasm. Cyclic voltammetry was performed on iminium type ions derived by protonation of the acridines. Reductions were generally reversible with potentials of about - 0.60 V. Involvement of quinoidal metabolites is also a possibility. The relationship of electrochemical behavior to structure and physiological activity is addressed
Using Network Extracted Ontologies to Identify Novel Genes with Roles in Appressorium Development in the Rice Blast Fungus Magnaporthe oryzae
This is the final version of the article. Available from MDPI via the DOI in this record.Magnaporthe oryzae is the causal agent of rice blast disease, the most important infection of rice worldwide. Half the world’s population depends on rice for its primary caloric intake and, as such, rice blast poses a serious threat to food security. The stages of M. oryzae infection are well defined, with the formation of an appressorium, a cell type that allows penetration of the plant cuticle, particularly well studied. However, many of the key pathways and genes involved in this disease stage are yet to be identified. In this study, I have used network-extracted ontologies (NeXOs), hierarchical structures inferred from RNA-Seq data, to identify pathways involved in appressorium development, which in turn highlights novel genes with potential roles in this process. This study illustrates the use of NeXOs for pathway identification from large-scale genomics data and also identifies novel genes with potential roles in disease. The methods presented here will be useful to study disease processes in other pathogenic species and these data represent predictions of novel targets for intervention in M. oryzae.This work was generously supported by the Wellcome Trust Institutional Strategic Support Award (WT105618MA)
Time in Television Narrative: Exploring Temporality in 21st Century Programming
This collection analyzes twenty-first-century American television programs that rely upon temporal and narrative experimentation. These shows play with time, slowing it down to unfold the narrative through time retardation and compression. They disrupt the chronological flow of time itself, using flashbacks and insisting that viewers be able to situate themselves in both the present and the past narrative threads. Although temporal play has existed on the small screen prior to the new millennium, never before has narrative time been so freely adapted in mainstream television. The essayists offer explanations for not only the frequency of time play in contemporary programming, but the implications of its sometimes disorienting presence. Drawing upon the fields of cultural studies, television scholarship, and literary studies, as well as overarching theories concerning postmodernity and narratology, Time in Television Narrative offers some critical suggestions. The increasing number of of television programs concerned with time may stem from any and all of the following: recent scientific approaches to quantum physics and temporality; new conceptions of history and posthistory; or trends in late-capitalistic production and consumption, in the new culture of instantaneity, or in the recent trauma culture amplified after the September 11 attacks. In short, these televisual time experiments may very well be an aesthetic response to the climate from which they derive. These essays analyze both ends of this continuum and also attend to another crucial variable: the television viewer watching this new temporal play

Twilight Follows Tradition: Analyzing Biting Critiques of Vampire Narratives for their Portrayals of Gender & Sexuality
Vampires have dominated print literature since the 18th century, eventually becoming more visible as they crossed mediated boundaries and genre divides. Now flourishing in neo-gothic realms like science fiction and fantasy, in print genres like chick-lit and young adult, and in the visual realm (from Hollywood’s big screen to daytime television’s sudsy small screen), vampire narratives are finding increased popularity. Stephenie Meyer’s Twilight series has shined a new spotlight on the all-encompassing umbrella genre that is “vamp lit,” and with it has come renewed attention to the so-called anti-feminist messages present in such narratives, such as the perceived negative characterization of the female protagonists and the problematic representation of female sexuality. Concerning the latter, many scholars have issues with the supposed abstinence themes present within the books and some claim that the main character is not in control of her own sexual awakening. The widely publicized debate over whether Meyer’s books should be classified as friends or foes of feminism exists as a foundation for this chapter. This essay examines the Twilight series as part of the longstanding tradition of vampire narratives – many seeped with contradictory gender portrayals and diverse depictions of sexuality. This article analyzes Twilight historically, as a product of its time and as a product of its textual predecessors. In doing so, it draws upon literary critiques of canonical texts like Bram Stoker’s Dracula (1897) and of best-selling books like Anne Rice’s The Vampire Chronicles (1976-2003), both of which have been made into Hollywood films. It also analyzes Twilight in terms of its target audience by comparing it to a popular young adult vampire series that predated it, L.J. Smith’s The Vampire Diaries (1991-1992), as well as to the television cult-phenomenon, Buffy the Vampire Slayer (1997-2003), both of which have also appeared in different mediated format
When Predator Becomes Prey: The Gendered Jargon of Popular Culture
Throughout the first decade of the twenty-first century the vernacular of popular culture has been bombarded by sexualized terminology. Although these terms are often formed with humorous intent, their staying power and use as cultural descriptive categories is both intriguing and disturbing. Also troubling is the fact that the majority of these new terms, such as puma (a thirty-something female “dating” a younger male), cougar (a forty-plus female “dating” a younger male), and MILF (“mother I’d like to fuck”), are restricted to the female gender alone. This article analyzes the etymology of these terms, their use in popular culture (ranging from reality television shows utilizing them as their namesake or coming of age films utilizing them as their punch line), and their overall reception in mainstream culture
Engaging Apolitical Adolescents: Analyzing the Popularity and Educational Potential of Dystopian Literature Post-9/11
Although dystopian novels have been prevalent under the young adult banner for decades, their abundance and popularity post-9/11 is noteworthy. The 21st century has found academics and laypersons alike discussing the supposed political apathy of young adults and teenagers of the Millennial Generation. However, despite this common complaint—and contrary to ample research that indicates that this age group has traditionally been uninterested in global politics—the reading preferences of this generation indicate that this label of apolitical may not be as fitting as some believe. In fact, the popularity of young adult dystopian literature, which is ripe with these political themes, suggests that this group is actually quite interested in these topics, although they often turn to the safe confines of fiction to wrestle with them. This article explores the potential educational uses of these young adult dystopias and argues that reading these texts may be a small step in the direction of engaging students in social justice issues and, perhaps, sparking more overt political action
