A toy model for brain criticality: self-organized excitation/inhibition ratio and the role of network clustering
Lorenz Baumgarten, Stefan Bornholdt
The critical brain hypothesis receives increasing support from recent experimental results. It postulates that the brain is at a critical point between an ordered and a chaotic reg…
Universal computation using localized limit-cycle attractors in neural networks
Lorenz Baumgarten, Stefan Bornholdt
Neural networks are dynamical systems that compute with their dynamics. One example is the Hopfield model, forming an associative memory which stores patterns as global attractors…
Self-organized criticality in neural networks from activity-based rewiring
Stefan Landmann, Lorenz Baumgarten, Stefan Bornholdt
Neural systems process information in a dynamical regime between silence and chaotic dynamics. This has lead to the criticality hypothesis which suggests that neural systems reach…
Epidemics with asymptomatic transmission: Sub-critical phase from recursive contact tracing
Lorenz Baumgarten, Stefan Bornholdt
The challenges presented by the COVID-19 epidemic have created a renewed interest in the development of new methods to combat infectious diseases. A prominent property of the SARS-…
Shallow shell theory of the buckling energy barrier: from the Pogorelov state to softening and imperfection sensitivity close to the buckling pressure
Lorenz Baumgarten, Jan Kierfeld
We study the axisymmetric response of a complete spherical shell under homogeneous compressive pressure to an additional point force. For a pressure below the classical cri…
Buckling of thermally fluctuating spherical shells: Parameter renormalization and thermally activated barrier crossing
Lorenz Baumgarten, Jan Kierfeld
We study the influence of thermal fluctuations on the buckling behavior of thin elastic capsules with spherical rest shape. Thermal fluctuations affect the buckling instability by…
