DynamO: A free O(N) general event-driven molecular-dynamics simulator

Molecular-dynamics algorithms for systems of particles interacting through discrete or "hard" potentials are fundamentally different to the methods for continuous or "soft" potential systems. Although many software packages have been developed for continuous potential systems, software for discrete potential systems based on event-driven algorithms are relatively scarce and specialized. We present DynamO, a general event-driven simulation package which displays the optimal O(N) asymptotic scaling of the computational cost with the number of particles N, rather than the O(N log(N)) scaling found in most standard algorithms. DynamO provides reference implementations of the best available event-driven algorithms. These techniques allow the rapid simulation of both complex and large (>10^6 particles) systems for long times. The performance of the program is benchmarked for elastic hard sphere systems, homogeneous cooling and sheared inelastic hard spheres, and equilibrium Lennard-Jones fluids.

En réponse à vulnérables paradoxes = In response to vulnerable paradoxes

"The event Vulnerable Paradoxes took place from May 27 to 30, 2020 as part of OFFTA. What was originally meant to be an in-person series of roundtables was moved online due to COVID-19. We invited thirteen artists, chosen by a selection committee, to speak about performance. We provided questions as a starting point: What qualities of performance are you searching for and why? How do form and content co-exist in your work and how does this relate to the ways in which you create and perform? How does the audience exist in your imagination and how does this compare to actual experiences with spectators? What can performance do that other art forms can’t? Is this connected to how and why you have chosen it? We tried to be clear that these questions were only a starting point. We wanted Vulnerable Paradoxes to be artist-driven and to allow the participants to speak of these matters in any way they chose. We wanted to generate a platform that would perhaps allow such matters to be spoken about in ways other than what we’re most used to." -- page 2

ZOM-FAM

"In their debut poetry collection, Kama La Mackerel mythologizes a queer/trans narrative of and for their home island, Mauritius. Composed of expansive lyric poems, ZOM-FAM (meaning “man-woman” or “transgender” in Mauritian Kreol) is a voyage into the coming of age of a gender-creative child growing up in the 80s and 90s on the plantation island, as they seek vocabularies for loving and honouring their queer/trans self amidst the legacy of colonial silences. Multiply voiced and imbued with complex storytelling, ZOM-FAM showcases a fluid narrative that summons ancestral voices, femme tongues, broken colonial languages, and a tender queer subjectivity, all of which grapple with the legacy of plantation servitude. Striking, vivid, tender, intimate, and political, ZOM-FAM is a beautifully wrought journey that articulates a contemporary decolonial poetics and offers a roadmap for colonized and displaced queer and trans voices to (re)imagine themselves into being." -- Publisher's website
