From Becoming-Woman to Becoming-Imperceptible: Self-Styled Death and Virtual Female Corpse in Digital Portraits of Cancer

Contemporary textual and visual representations of cancer engage self-reflectively with death and dying, yet they often rely on normative notion of death as the end of an individual life. This article focuses on stylised cancer portraits of the young German Nana Stäcker which she took in collaboration with her mother and professional photographers during her chemotherapy and until her death. Intervening in the field of Queer Death Studies this article explores if and how these images allow us to rethink normative Western notions of death. Drawing on Rosi Braidotti’s posthuman theory of death and of female subjectivity, I argue that the photo shoots recast Nana’s illness and dying as a gendered and creative process of subject formation beyond individual death. Through creating aestheticised and eroticised camp images, Nana playfully performs und subverts a range of iconic Western femininities and styles both life and death as a constant becoming. Portraits of Nana as virtual female corpse further highlight this continuity of life and death by reinserting death into life. While these images resist a necropolitical engagement with cancer and dying, they suggest an impersonal and affirmative understanding of death that opens up bioethical questions about contemporary cultures of longevity and health.&nbsp

Free-energy landscape of the villin headpiece in an all-atom force field

SummaryWe investigate the landscape of the internal free-energy of the 36 amino acid villin headpiece with a modified basin hopping method in the all-atom force field PFF01, which was previously used to predictively fold several helical proteins with atomic resolution. We identify near native conformations of the protein as the global optimum of the force field. More than half of the twenty best simulations started from random initial conditions converge to the folding funnel of the native conformation, but several competing low-energy metastable conformations were observed. From 76,000 independently generated conformations we derived a decoy tree which illustrates the topological structure of the entire low-energy part of the free-energy landscape and characterizes the ensemble of metastable conformations. These emerge as similar in secondary content, but differ in tertiary arrangement

Spaces of Community in Champaign-Urbana

Our research question was to focus on how the Champaign Public Library (pictured below), the Virginia Theater (right), and Meadowbrook Park (far right) have contributed to the culture of Champaign Urbana as a whole. Being a community that represents different cultures from many diverse backgrounds, we wanted to focus on the contribution to this diversity of different spaces, which we feel best represent Champaign Urbana

Thermochemistry and photochemistry of spiroketals derived from indan-2-one: stepwise processes versus coarctate fragmentations

Coarctate reactions are defined as reactions that include atoms at which two bonds are made and two bonds are broken simultaneously. In the pursuit of the discovery of new coarctate reactions we investigate the fragmentation reactions of cyclic ketals. Three ketals with different ring sizes derived from indan-2-one were decomposed by photolysis and pyrolysis. Particularly clean is the photolysis of the indan-2-one ketal 1, which gives o-quinodimethane, carbon dioxide and ethylene. The mechanism formally corresponds to a photochemically allowed coarctate fragmentation. Pyrolysis of the five-ring ketal yields a number of products. This is in agreement with the fact that coarctate fragmentation observed upon irradiation would be thermochemically forbidden, although this exclusion principle does not hold for chelotropic reactions. In contrast, fragmentation of the seven-ring ketal 3 is thermochemically allowed and photochemically forbidden. Upon pyrolysis of 3 several products were isolated that could be explained by a coarctate fragmentation. However, the reaction is less clean and stepwise mechanisms may compete
