135. Potts spins, protein conformations and implicit water modelArtem Badasyan, 2023, objavljeni povzetek znanstvenega prispevka na konferenci (vabljeno predavanje) Opis: I will summarize past and current achievements in the field of spin model applications to protein conformations. Using classical Statistical Mechanics scheme and 1D many-body Hamiltonian, exact partition function can be estimated, giving access to the free energy, order parameter and specific heat. I will introduce a simplified water model as an additive term at the level of Hamiltonian, and will show how the solvent degrees of freedom can be summed out. The suggested procedure results in the effective Hamiltonian with the temperature dependent hydrogen bonding energy. If the many-body range is reduced to the nearest neighbour, the approach reduces to the Zimm-Bragg model. Obtained expressions for the order parameter and the specific heat nicely fit to the corresponding experiments for protein folding, providing an alternative or complementary scheme for the processing of experimental data.

136. Dancing sympathy beyond human failure : Artistic Research as Cosmopolitical DefuturingPeter Purg, 2023, izvirni znanstveni članek Opis: abstract
The article explores the concepts, tools and methods that may be taken on board by artistic researchers when venturing into uncertain futures. The approaching hay-day of Artistic Research calls for a repositioning of this academic and cultural avantgarde that is assuming real power and must thus take clear opposition against dominant politics and corporate capitalism keeping the human and non-human kinds in perpetual crisis. Next to Science and Technology, Art has finally reached a status of an equivalued cornerstone, and within this level playing field a new research-based approach is needed where power relationships, decision-making mechanisms, dominant narratives or prevalent aesthetics are boldly investigated and critically questioned, (re)instituting the importance of artistic disruption and establishing art-thinking as the key to not only question but also design pathways to meaningful change. Deeply intertwined research methodologies ranging from social to natural sciences, from humanities via (critically reflected) technologies to the (technologically emancipated) arts, should be left to safely mingle and mutually inspire. Rather than colonizing it with yet another false supremacy, we should be learning from the Global South, where collective dancing, storytelling or performing still presents a norm of how to generate new knowledge or reach consensus. Artistic Research can contribute to crafting better worlds even once AI entities get accepted as fellow researchers (if not dancers), their agency reflected in an attitude of radical sympathy (re)instituting care, justice and solidarity by ways of sound research activism.
