Frontiers in Bioengineering and Biotechnology, 2019 Defective interfering particles (DIPs) are a natural byproduct of influenza A virus (IAV) replication. DIPs interfere with the propagation and spread of infectious standard virus (STV), reduce virus yields by competing for viral and cellular resources ...

Complex dynamics in nanosystems
Physical Review E, 2013 Complex dynamics associated with multistability have been studied extensively in the past but mostly for low-dimensional nonlinear dynamical systems. A question of fundamental interest is whether multistability can arise in high-dimensional physical systems.

Using systems thinking, system dynamics and simulation for sustainability education: A study design [PDF]
, 2022 Education for Sustainable Development (ESD) is vital to the success of the United Nation¿s Sustainable Development Goals (SDGs). There is broad consensus that it requires active, participative and experiential learning methods, underpinned by systemic ...

Dynamics and Complexity of Computrons [PDF]
Entropy, 2020 We investigate chaoticity and complexity of a binary general network automata of finite size with external input which we call a computron. As a generalization of cellular automata, computrons can have non-uniform cell rules, non-regular cell connectivity and an external input. We show that any finite-state machine can be represented as a computron and

Complexity and Dynamical Depth [PDF]
Information, 2014 We argue that a critical difference distinguishing machines from organisms and computers from brains is not complexity in a structural sense, but a difference in dynamical organization that is not well accounted for by current complexity measures.

On the complexity of dynamic submodular maximization
Proceedings of the 54th Annual ACM SIGACT Symposium on Theory of Computing, 2022 We study dynamic algorithms for the problem of maximizing a monotone submodular function over a stream of $n$ insertions and deletions. We show that any algorithm that maintains a $(0.5+ε)$-approximate solution under a cardinality constraint, for any constant $ε>0$, must have an amortized query complexity that is $\mathit{polynomial}$ in $n ...

The dynamic complexity of formal languages [PDF]
ACM Transactions on Computational Logic, 2012 The article investigates the power of the dynamic complexity classes D yn FO, D yn QF, and D yn PROP over string languages. The latter two classes contain problems that can be maintained using quantifier-free first-order updates, with and without auxiliary functions ...
