Towards Turkish American Literature

The author expands the definition of Turkish American literature beyond fiction written by Americans of Turkish descent to incorporate texts that literally ‘commute’ between two national spheres. This segment of Turkish American literature transcends established paradigms of immigrant life-writing, as it includes works by Turkish authors who do not qualify as American permanent residents and were not born in the United States by Turkish parents (such as Elif Shafak and Halide Edip), and on novels where the Turkish and Ottoman matter decisively prevails over the American (Güneli Gün’s «On the Road to Baghdad» and Alev Lytle Croutier’s «Seven Houses»). Yet, these texts were written in English, were purposefully located on the American market, and simultaneously engage the Turkish and the American cultural and literary traditions

The Reluctant Islamophobes: Multimedia Dissensus in the Hollywood Premodern

This paper contributes to the theorization of how Orientalism has evolved after 9/11 and in the first two decades of the twenty-first century. I specifically address the multimediality of films and propose that post-9/11 Orientalism has fragmented into more digestible, more complex micronarratives dispersed throughout the interplay of different media which constitute the film experience. I recur to Foucault’s concept of dispositif to illustrate how any of these media—such as music, screenplay, editing, acting, etc.—may “[enter] into resonance or contradiction with the others” (Foucault 195), ambiguating the film’s politics. When the film’s different media pursue diverging politics, I speak of multimedia dissensus. In order to test this hypothesis, I focus on two films which explicitly champion diversity and aim to reverse the logics of Islamophobia by presenting tributes to Muslim culture or denunciations of Eurocentric discriminatory practices: Alejandro Amenábar’s Agora (2009) and Ridley Scott’s Kingdom of Heaven (2005). A more detailed analysis of the films’ multimedial complexity, however, shows that they do participate in the Islamophobic discourses that have dominated Hollywood cinema after 9/11

The Effects of Dark Matter Decay and Annihilation on the High-Redshift 21 cm Background

The radiation background produced by the 21 cm spin-flip transition of neutral hydrogen at high redshifts can be a pristine probe of fundamental physics and cosmology. At z~30-300, the intergalactic medium (IGM) is visible in 21 cm absorption against the cosmic microwave background (CMB), with a strength that depends on the thermal (and ionization) history of the IGM. Here we examine the constraints this background can place on dark matter decay and annihilation, which could heat and ionize the IGM through the production of high-energy particles. Using a simple model for dark matter decay, we show that, if the decay energy is immediately injected into the IGM, the 21 cm background can detect energy injection rates >10^{-24} eV cm^{-3} sec^{-1}. If all the dark matter is subject to decay, this allows us to constrain dark matter lifetimes <10^{27} sec. Such energy injection rates are much smaller than those typically probed by the CMB power spectra. The expected brightness temperature fluctuations at z~50 are a fraction of a mK and can vary from the standard calculation by up to an order of magnitude, although the difference can be significantly smaller if some of the decay products free stream to lower redshifts. For self-annihilating dark matter, the fluctuation amplitude can differ by a factor <2 from the standard calculation at z~50. Note also that, in contrast to the CMB, the 21 cm probe is sensitive to both the ionization fraction and the IGM temperature, in principle allowing better constraints on the decay process and heating history. We also show that strong IGM heating and ionization can lead to an enhanced H_2 abundance, which may affect the earliest generations of stars and galaxies.Comment: submitted to Phys Rev D, 14 pages, 8 figure

Altitudinal training sets of pollen rain – vegetation cover and modelled climate as a tool for the interpretation of paleoecological records

To improve our ability to reconstruct past environments and climate from fossil pollen records, modern proxy calibration studies along climatic and ecological gradients are needed. Here we present the first training set of modern pollen rain, vegetation, climate and terrain parameters developed along a 1700m-high transect in the western Italian Alps. The accurate knowledge on the relationships between these factors is essential for robust and sound reconstructions of past ecosystems based on microscopic plant remains

The FAMU experiment at RIKEN-RAL to study the muon transfer rate from hydrogen to other gases

The aim of the FAMU (Fisica degli Atomi Muonici) experiment is to realize the first measurement of the hyperfine splitting (hfs) in the 1S state of muonic hydrogen _Ehf s 1S , by using the RIKEN-RAL intense pulsed muon beam and a high-energy mid-infrared tunable laser. This requires a detailed study of the muon transfer mechanism at different temperatures and hence at different epithermal states of the muonic system. The experimental setup involves a cryogenic pressurized gas target and a detection system based on silicon photomultipliers-fiber beam hodoscopes and high purity Germanium detectors and Cerium doped Lanthanium Bromide crystals, for X-rays detection at energies around 100 keV. Simulation, construction and detector performances of the FAMU apparatus at RAL are reported in this paper
