q-Moments remove the degeneracy associated with the inversion of the q-Fourier transform

It was recently proven [Hilhorst, JSTAT, P10023 (2010)] that the q-generalization of the Fourier transform is not invertible in the full space of probability density functions for q > 1. It has also been recently shown that this complication disappears if we dispose of the q-Fourier transform not only of the function itself, but also of all of its shifts [Jauregui and Tsallis, Phys. Lett. A 375, 2085 (2011)]. Here we show that another road exists for completely removing the degeneracy associated with the inversion of the q-Fourier transform of a given probability density function. Indeed, it is possible to determine this density if we dispose of some extra information related to its q-moments.Comment: 11 pages, 12 figure

Conceptual design and integration of a space station resistojet propulsion assembly

The resistojet propulsion module is designed as a simple, long life, low risk system offering operational flexibility to the space station program. It can dispose of a wide variety of typical space station waste fluids by using them as propellants for orbital maintenance. A high temperature mode offers relatively high specific impulse with long life while a low temperature mode can propulsively dispose of mixtures that contain oxygen or hydrocarbons without reducing thruster life or generating particulates in the plume. A low duty cycle and a plume that is confined to a small aft region minimizes the impacts on the users. Simple interfaces with other space station systems facilitate integration. It is concluded that there are no major obstacles and many advantages to developing, installing, and operating a resistojet propulsion module aboard the Initial Operational Capability (IOC) space station

A two-stage, two-organism process for biohydrogen from glucose

H2 can potentially be produced in a two-stage biological process: the fermentation of glucose by Escherichia coli HD701 and the photofermentation of the residual medium by Rhodobacter sphaeroides O.U. 001. In a typical batch fermentation, E. coli consumed glucose and produced H2, organic end-products and biomass. Organic end-products and residual glucose were removed during subsequent photofermentation by R. sphaeroides, with associated growth and neutralization of pH. However, photoproduction of H2 did not occur during photofermentation of the residual liquor per se due to the presence of fixed nitrogen compounds. Nevertheless, this two-stage approach could be applied to dispose of sugar-containing industrial wastes, H2 being used for on-site power generation

Report on a Right of Use for Collateral Takers and Custodians

The Report on a Right of Use for Collateral Takers and Custodians examines on what basis collateral takers can dispose of the assets of collateral providers, and custodians of those of their clients. The report describes the current legal practice in the USA, Denmark, The Netherlands, Germany, Italy and the UK. It critically examines legislative initiatives by UNIDROIT (Project on Harmonised Substantive Rules regarding Securities Held with an Intermediary) and in the European Union (Collateral Directive, Investment Services Directive). The report contains a Tax Appendix.collateral, right of use, repo, securities lending, derivatives

Tolkien’s Sub-Creation and Secondary Worlds: Implications for a Robust Moral Psychology

In his work, “On Fairy Stories,” J. R. R. Tolkien offers a detailed account of what he calls Sub-creation, along with the corresponding notions of Primary and Secondary Worlds. In this paper, I suggest that Tolkien’s concept of Sub-creation can be creatively appropriated in the realm of moral psychology and there applied to the fundamental relationship between self and other – or in Judeo-Christian terms, “I” and my neighbor. Through appeal to Tolkien’s thought and to the wider Christian theological tradition, and in constructive tension with the contemporary psychoanalytic attention to “intersubjectivity,” I attempt to elucidate the power and appropriate function of the human imagination to dispose us to good moral action, and so to bring us closer to ultimate happiness
