Drivers’ decision-making when attempting to cross an intersection results from choice between affordances

open access: yesFrontiers in Human Neuroscience, 2015
In theory, a safe approach to an intersection implies that the driver can simultaneously manage two scenarios: they either cross or they must give way to an oncoming vehicle.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS 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 ...

Granger causality and stopping times*

open access: yes, 2016
© 2016, Springer Science+Business Media New York. We consider causality relationships between σ-fields (filtrations) associated by stopping times, which can be applied to the stopped processes.

Subgeometric Ergodicity under Random-Time State-Dependent Drift Conditions

open access: yesJournal of Probability and Statistics, 2014
Motivated by possible applications of Lyapunov techniques in the stability of stochastic networks, subgeometric ergodicity of Markov chains is investigated.

Inhibitory control processes and the strategies that support them during hand and eye movements

open access: yesFrontiers in Psychology, 2016
Background and Aims: Adaptive behavior depends on the ability to voluntarily suppress context-inappropriate behaviors, a process referred to as response inhibition. Stop Signal tests (SSTs) are the most frequently studied paradigm used to assess response

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

On an Effective Solution of the Optimal Stopping Problem for Random Walks [PDF]

open access: yes
We find a solution of the optimal stopping problem for the case when a reward function is an integer function of a random walk on an infinite time interval. It is shown that an optimal stopping time is a first crossing time through a level defined as the

Faster comparison of stopping times by nested conditional Monte Carlo

open access: yes, 2016
We show that deliberately introducing a nested simulation stage can lead to significant variance reductions when comparing two stopping times by Monte Carlo.

Stopping Times of Boundaries: Relaxation and Continuity [PDF]

open access: yes, 2023
We study the properties of the free boundaries and the corresponding hitting times in the context of optimal stopping in discrete time. We first prove the continuity of the map from the boundaries to the expected value of the corresponding stopping ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
