Geografie del soggetto nel pensiero deleuziano
Get PDFThis article focuses on Deleuze’s critique of the notion of subject. The French author wants to replace the inveterate image of the individual -often thought of as a monolithic tabernacle or as a reified ὑποκείμενον-, with the more fluid representation of a subjectivity in motion, composed of events, effects, “zig-zag”, intensity and speed that proceeding at various stratigraphic levels, composes geographies of lines, heterogeneous in their variability. Deleuze, however, does not stop here. Indeed, the Deleuzian intent does not lie solely in the desire to weaken the idea of subjectivity. He asks for something more, stripping away from any residual form of anthropocentrism: the goal of Ethics is becoming-impersonal. In the first section the article focuses on a fundamental question: what space is assigned to subjectivity, in an impersonal ontology, where experience is configured as a pure flow? In the second part of the text, I take into account three types of concepts that further demonstrate the fluidity of the subject: the notion of the individual as composed of lines, the notion of limit and the notion of becoming, in particular of becoming-other. Ultimately, the aim of the article is to highlight how Deleuze’s thought is an indispensable starting point to build a fruitful, non-dogmatic and non-reifying philosophical investigation of the concept of subject, proposing however some critical notes

Eu-Doped Pyrochlore Crystal Nano-Powders as Fluorescent Solid for Fingerprint Visualization and for Anti-Counterfeiting Applications
No full textUndoped Y2Sn2O7 and Eu3+ doped Y2Sn2O7 samples with doping concentrations 7%, 8%, 9%, and 10% are successfully synthesized by the co-precipitation method. A complete structural, morphological, and spectroscopic characterization is carried out. XRD measurements reveal that samples crystallize in the pure single pyrochlore phase and Eu3+ ions occupy sites with D3d symmetry. After mechanical grinding, the average crystallite size is less than 100 nm for all compositions. Optical characterization shows emission from the 5D0 level towards the lower lying 7F0,1,2,3,4 levels. The CIE color coordinates of all the pyrochlore phosphors are very close to those of the ideal red light. For the visualization of latent fingerprints, different surfaces are tested, including difficult ones (wood and ceramic), with excellent results. All three levels of fingerprint ridge patterns are visualized: core (Level 1), bifurcation and termination (Level 2), and sweat pores (Level 3). Moreover, our nano-powders are used to prepare a stable fluorescent ink

Transplanted human adipose tissue-derived stem cells engraft and induce regeneration in mice olfactory neuroepithelium in response to dichlobenil subministration
Get PDFWe used immunodeficient mice, whose dorsomedial olfactory region was permanently damaged by dichlobenil inoculation, to test the neuroregenerative properties of transplanted human adipose tissue-derived stem cells after 30 and 60 days. Analysis of polymerase chain reaction bands revealed that stem cells preferentially engrafted in the lesioned olfactory epithelium compared with undamaged mucosa of untreated transplanted mice. Although basal cell proliferation in untransplanted lesioned mice did not give rise to neuronal cells in the olfactory mucosa, we observed clusters of differentiating olfactory cells in transplanted mice. After 30 days, and even more at 60 days, epithelial thickness was partially recovered to normal values, as also the immunohistochemical properties. Functional reactivity to odorant stimulation was also confirmed through electroolfactogram recording in the dorsomedial epithelium. Furthermore, we demonstrated that engrafted stem cells fused with mouse cells in the olfactory organ, even if heterokaryons detected were too rare to hypothesize they directly repopulated the lesioned epithelium. The data reported prove that the migrating transplanted stem cells were able to induce a neuroregenerative process in a specific lesioned sensory area, enforcing the perspective that they could become an available tool for stem cell therapy. © The Author 2014.

On quasi-tame Looijenga pairs
Get PDFWe prove a conjecture of Bousseau, van Garrel and the first-named author
relating, under suitable positivity conditions, the higher genus maximal
contact log Gromov-Witten invariants of Looijenga pairs to other curve counting
invariants of Gromov-Witten/Gopakumar-Vafa type. The proof consists of a
closed-form -hypergeometric resummation of the quantum tropical vertex
calculation of the log invariants in presence of infinite scattering. The
resulting identity of -series appears to be new and of independent
combinatorial interest.Comment: 15 pages. v2: minor changes, explanations added, 18 pages. Version
