Relaxation to magnetohydrodynamics equilibria via collision brackets
Metriplectic dynamics is applied to compute equilibria of fluid dynamical
systems. The result is a relaxation method in which Hamiltonian dynamics
(symplectic structure) is combined with dissipative mechanisms (metric
structure) that relaxes the system to the desired equilibrium point. The
specific metric operator, which is considered in this work, is formally
analogous to the Landau collision operator. These ideas are illustrated by
means of case studies. The considered physical models are the Euler equations
in vorticity form, the Grad-Shafranov equation, and force-free MHD equilibria.Comment: Conference Proceeding (Theory of Fusions Plasmas, 2018), 9 pages, 8

Misja: epidemia. Strach przed mutacjÄ jako podstawa ĆwiatotwĂłrcza gier z trylogii StarCraft II
In the chapter Mission: Outbreak. A Fear of Mutation as the World-building Basis for the StarCraft II Trilogy, Krzysztof M. Maj recognizes the postmodern reinterpre-tation of the figure of the zombie in real-time-strategy-based world-building. Having considered a zombie-centric narrative as central to both the game mechanics (survival scenarios in zombie-infested gameworlds, fortification and last-stands design in tower defense games etc.) and to the retroactive nature of post-apocalypse (zombies as remi-niscence of a former human form), the author proceeds with a detailed analysis of the two major aspects of the StarCraft II storyline: the anthropocentric fear of muta-tion and xenonological need for evolution through assimilation. All things consid-ered, the chapter invites a critical reading of postcolonial and paradigmatic discourses that allows Terrans and the Protoss to reduce the Zergâs xenobiological ability to evolve through infesting other lifeforms and absorbing their genetic material to a mere parasitism and a travesty of the process of natural evolution. Interpreted as zombie-like xenomorphs, the Zerg seem to reveal an unexpected depth in their design which all the more contributes to a better understanding of how the myth of zombism may influence science fiction and fantastic world-building.OĆrodek Badawczy Facta Fict
Ksenologia i ksenotopografia Bernharda Waldenfelsa wobec podstawowych zaĆoĆŒeĆ ĆwiatotwĂłrczych literatury fantastycznej (Orson Scott Card, Neil Gaiman, George R. R. Martin)
XENOLOGY AND XENOTOPOGRAPHY OF BERNHARD WALDENFELS
The paper strives to adapt Bernhard Waldenfelsâ xenology and so called
âxenotopographyâ for the philosophico-literary studies in fantastic
world-building with a special concern of the âportal-questâ model of fantasy
and SF. Following Waldenfelâs remarks on the nature of post-
Husserlian diastasis of our world [Heimwelt] and otherworld
[Fremdwelt] and acknowledging the consequences of allocating oneâs
attitude towards the otherness in the symbolical borderland [âsphere of
intermondeâ] in between, it is examined whether such a model can occur
in the fantastic literature and what may be the consequence of xenotopographic
reconsideration of its basic ontological premises. Additionally,
the article offers an original xenotopograpfic model of worldbuilding
which addresses three carefully chosen case studies of fantastic
worlds from Orson Scott Cardâs Enderâs Game tetralogy, Neil Gaimanâs
Stardust and George R. R. Martinâs The Song of Ice and Fire. In the
end, it is suggested that hitherto presented xenotopography gravely
inspired a postmodern shift in the genres of fantasy and SF which results
in more ethically conscious representations of the otherness and
even more concise and alien comprehensive world-building
Groza systemowej niewiedzy. O dystopijnej rzeczywistoĆci "PrzeglÄ du KoĆca Ćwiata" Miry Grant
In the chapter Horror of the Systemic Unawareness. On A Dystopian Reality of Mira Grantâs âNewslfeshâ Krzysztof M. Maj invites a Foucauldian reading of the epony-mous fear of being unaware of the truth about the âfounding lieâ of dystopian socio-stasis. While doing so, he proceeds with an analysis of the basic components of dysto-pian narrative, pondering on the subtle relationships between the so-called young adult dystopias, postapocalyptic lore, and âpolitical technology of the bodyââwith the latter being an ultimate tool of authoritatian control observed in Newsflesh trilogy. Simultaneously, the chapter serves as a concise introduction to contemporary world-centered dystopian narratives, greatly inspired by a deconstructive approach to utopian and dystopian studies, with a particular emphasis on the subversion of metaphysical paradigms and binary oppositions, critique of logocentrism and panopticism, or dis-semination of power/knowledge. Finally, Maj argues that the state of unawareness may be both a curse and a blessing in a dystopian realityâa curse, as it strikes fear into the hearts of subdued citizens who learn thereby to be afraid of any rebellious activities, and a blessing, as it may inspire a strong individual to overcome their fear and challenge the reign of oppressive authorities.Krzysztof M.
