Process dynamics in delay discounting decisions: An attractor dynamics approach [PDF]
Judgment and Decision Making, 2016 How do people make decisions between an immediate but small reward and a delayed but large one? The outcome of such decisions indicates that people discount rewards by their delay and hence these outcomes are well described by discounting functions ...

Timing of transients: quantifying reaching times and transient behavior in complex systems
New Journal of Physics, 2017 In dynamical systems, one may ask how long it takes for a trajectory to reach the attractor, i.e. how long it spends in the transient phase. Although for a single trajectory the mathematically precise answer may be infinity, it still makes sense to ...

Applied symbolic dynamics: attractors and filtrations
Discrete and Continuous Dynamical Systems, 1999 The paper is devoted to the structure of attractors without any preliminary information about the system. The investigation is based on the methods of symbolic dynamics and all necessary information is obtained by numerical methods. Using a covering of phase space by cells the dynamical system is associated with an oriented graph called symbolic image ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Frontiers in Neuroscience, 2017 Synaptic Plasticity, the foundation for learning and memory formation in the human brain, manifests in various forms. Here, we combine the standard spike timing correlation based Hebbian plasticity with a non-Hebbian synaptic decay mechanism for training

FEBS Open Bio, EarlyView.UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Landmark-Based Updating of the Head Direction System by Retrosplenial Cortex: A Computational Model
Frontiers in Cellular Neuroscience, 2018 Maintaining a sense of direction is fundamental to navigation, and is achieved in the brain by a network of head direction (HD) cells, which update their signal using stable environmental landmarks.

Asymptotic Dynamics in the Heisenberg Picture: Attractor Subspace and Choi-Effros Product
We study the asymptotic dynamics of open quantum systems in the Heisenberg picture. We find an explicit expression for the attractor subspace and the dynamics that takes place in it.

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Frontiers in Computational Neuroscience, 2015 Head direction cells fire to signal the direction in which an animal's head is pointing. They are able to track head direction using only internally-derived information (path integration).
