Societal self-regulation induces complex infection dynamics and chaos

Authors Wagner J, Bauer S, Contreras S, Fleddermann L, Parlitz U, Priesemann V Journal Physical Review Research Citation Phys. Rev. Research 7, 013308. Abstract Classically, endemic infectious diseases are expected to display relatively stable, predictable infection dynamics. Accordingly, basic disease models such as the susceptible-infected-recovered-susceptible model display stable endemic states

PHluorin-conjugated secondary nanobodies as a tool for measuring synaptic vesicle exo- and endocytosis

Authors Georgiev SV, Rizzoli SO Journal Scientific Reports Citation Sci Rep 15, 10093 (2025). Abstract Neuronal communication relies on synaptic vesicle recycling, which has long been investigated by live imaging approaches. Synapto-pHluorins, genetically encoded reporters that incorporate a pH-sensitive variant of GFP within the lumen of the synaptic vesicle, have

On the Uniqueness of Kantorovich Potentials

Authors Staudt T, Hundrieser S, Munk A Journal arXiv Citation arXiv:2201.08316. Abstract Kantorovich potentials denote the dual solutions of the renowned optimal transportation problem. Uniqueness of these solutions is relevant from both a theoretical and an algorithmic point of view, and has recently emerged as a necessary condition for asymptotic
