Universal Scaling in the Aging of the Strong Glass Former SiO2_2

We show that the aging dynamics of a strong glass former displays a strikingly simple scaling behavior, connecting the average dynamics with its fluctuations, namely the dynamical heterogeneities. We perform molecular dynamics simulations of SiO$_2$ with BKS interactions, quenching the system from high to low temperature, and study the evolution of the system as a function of the waiting time $t_{\rm w}$ measured from the instant of the quench. We find that both the aging behavior of the dynamic susceptibility $\chi_4$ and the aging behavior of the probability distribution $P(f_{{\rm s},{\mathbf r}})$ of the local incoherent intermediate scattering function $f_{{\rm s},{\mathbf r}}$ can be described by simple scaling forms in terms of the global incoherent intermediate scattering function $C$. The scaling forms are the same that have been found to describe the aging of several fragile glass formers and that, in the case of $P(f_{{\rm s},{\mathbf r}})$, have been also predicted theoretically. A thorough study of the length scales involved highlights the importance of intermediate length scales. We also analyze directly the scaling dependence on particle type and on wavevector $q$, and find that both the average and the fluctuations of the slow aging dynamics are controlled by a unique aging clock, which is not only independent of the wavevector $q$, but is the same for O and Si atoms.Comment: 13 pages, 21 figures (postscript

Thus he rode sorowyng : Travel Narratives and the Ethics of Sexual Behavior in Le Morte d\u27Arthur

Arthurian romance is normally characterized by a highly precise travel trajectory in which knights leave the Round Table in search of “aventure” and subsequently return. At the same time, the search for “aventure” involves what seems like much random meandering. In this essay, I theorize a logic to this knightly wandering. I argue that travel in Sir Thomas Malory’s Arthurian oeuvre is inextricably linked to sexual behavior. The code of sexual ethics engendered by travel narratives applies equally to males and females. Male and female sexual transgressors are condemned to equally constraining travel narratives, while virgins of both sexes enjoy a kind of free mobility. Chivalry dictates the need for a very particular kind of travel. In constructing a fixed link between sexual ethics and travel, Malory’s narratives code sexual behavior as an ethical determiner of chivalry

The Theatricality of Transformation: cross-dressing and gender/sexuality spectra on the Elizabethan stage

Feminist scholars of Shakespeare and contemporaries have become increasingly interested in the practice of cross-dressing on the early modern English stage in the past few decades. While much of this critical interest has revolved around relationships between the cross-dressed persona and real early modern patriarchy, this paper seeks to subvert some of the long-standing gendered binaries that dominate this field. This paper uses late 16th and early 17th century legal records to examine the nature of the discourse surrounding sexual misdemeanor in early modern England and returns to instances of staged cross-dressing to argue that the cross-dresser was an object of fascination for the early modern viewer for the same reasons the virgin and the young boy were equally spectacles. Arguing against the notion that staged cross-dressing was solely and primarily about gender, I instead suggest that the cross-dressed actor is a spectacular sight because he is arrested in a state of potentiality, always on the verge of a specifically performative and theatrical transformation

Plant functional traits mediate above- and belowground species interactions in ecological communities

Functional plant traits provide a means whereby species identity can influence above- and belowground community interactions. To examine the role of plant functional traits in shaping ecological communities, Chapter 1 examines how the evolution of functional differences between closely related groups of endemic and non-endemic species influence associated species interactions, and Chapter 2 examines how plant functional traits can influence associated community composition
