On connectivity in random graph models with limited dependencies
(2024)Random Structures & AlgorithmsWe consider random graph models in which the events describing the inclusion of potential edges have to be independent of each other if the corresponding edges are non-adjacent and ask: what is the minimum probability rho(n), such that for any distribution G (in this model) on graphs with n vertices in which each potential edge has a marginal probability of being present at least rho(n), a graph drawn from G is connected with non-zero ...Journal Article -

Message-passing on hypergraphs: detectability, phase transitions and higher-order information
(2024)JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENTHypergraphs are widely adopted tools to examine systems with higher-order interactions. Despite recent advancements in methods for community detection in these systems, we still lack a theoretical analysis of their detectability limits. Here, we derive closed-form bounds for community detection in hypergraphs. Using a message-passing formulation, we demonstrate that detectability depends on the hypergraphs' structural properties, such as ...Journal Article -

Molecular mechanism of α-synuclein aggregation on lipid membranes revealed
(2024)Chemical ScienceThe central hallmark of Parkinson's disease pathology is the aggregation of the alpha-synuclein protein, which, in its healthy form, is associated with lipid membranes. Purified monomeric alpha-synuclein is relatively stable in vitro, but its aggregation can be triggered by the presence of lipid vesicles. Despite this central importance of lipids in the context of alpha-synuclein aggregation, their detailed mechanistic role in this process ...Journal Article -

Radiative asymptotic symmetries of 3D Einstein-Maxwell theory
(2024)SciPost PhysicsWe study the null asymptotic structure of Einstein–Maxwell theory in three-dimensional (3D) spacetimes. Although devoid of bulk gravitational degrees of freedom, the system admits a massless photon and can therefore accommodate electromagnetic radiation. We derive fall-off conditions for the Maxwell field that contain both Coulombic and radiative modes with non-vanishing news. The latter produces non-integrability and fluxes in the ...Journal Article -

Deep CO<sub>2</sub> release and the carbon budget of the central Apennines modulated by geodynamics
(2024)Nature GeoscienceRecent studies increasingly recognize the importance of critical-zone weathering during mountain building for long-term CO2 drawdown and release. However, the focus on near-surface weathering reactions commonly does not account for CO2 emissions from the crust, which could outstrip CO2 drawdown where carbonates melt and decarbonize during subduction and metamorphism. We analyse water chemistry from streams in Italy's central Apennines ...Journal Article -
