BACH, a Bayesian Optimization Protocol for Accurate Coarse‐Grained Parameterization of Organic Liquids

Advanced Functional Materials, EarlyView.
We present a fully automated Bayesian optimization (BO) protocol for the parameterization of nonbonded interactions in coarse‐grain CG force fields (BACH). Using experimental thermophysical data, we apply the protocol to a broad range of liquids, spanning linear, branched, and unsaturated hydrocarbons, esters, triglycerides, and water.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

Advanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

Stop-signal task difficulty and the right inferior frontal gyrus

Behavioural Brain Research, 2013
The stop-signal paradigm is increasingly being used as a probe of response inhibition in basic and clinical neuroimaging research. The critical feature of this task is that a cued response is countermanded by a secondary 'stop-signal' stimulus offset from the first by a 'stop-signal delay'.

Suppression of human cortico-motoneuronal excitability during the Stop-signal task

Clinical Neurophysiology, 2009
To investigate whether motor suppression is an active process, and to clarify its somatotopic organization, we investigated cortico-motoneuronal excitability using transcranial magnetic stimulation (TMS) during the Stop-signal task.Subjects were asked to press a button following a Go cue; a Stop-signal followed the Go cue by a certain time delay in 25%

Stop-signal delay reflects response selection duration in stop-signal task

Attention, Perception, & Psychophysics, 2023
The stop-signal task (SST) is widely used for studying the speed of the latent process of response inhibition. The SST patterns are typically explained by a horse-race model (HRM) with supposed Go and Stop processes. However, HRM does not agree with the sequential-stage model of response control. As a result, the exact relationship between the response

Causal Prefrontal Contributions to Stop-Signal Task Performance in Humans

Journal of Cognitive Neuroscience, 2021
Abstract The frontal lobes have long been implicated in inhibitory control, but a full understanding of the underlying mechanisms remains elusive. The stop-signal task has been widely used to probe instructed response inhibition in cognitive neuroscience.

Preparation facilitates response inhibition based on a stop‐signal task

PsyCh Journal, 2023
AbstractThis study demonstrated that the higher stop‐signal probability condition showed a longer go reaction time and shorter stop‐signal reaction time (SSRT) compared with the lower stop‐signal probability condition. In addition, preparation cost was correlated with SSRT. These results suggest that preparation facilitates response inhibition.

Sustained brain activation supporting stop‐signal task performance

European Journal of Neuroscience, 2014
AbstractStop‐signal paradigms operationalize a basic test of goal‐directed behaviour whereby an overarching stop goal that is performed intermittently must be maintained throughout ongoing performance of a reaction time go task (go goal). Previous studies of sustained brain activation during stop‐signal task performance in humans did not observe ...

Neural aftereffects of errors in a stop-signal task

Neuropsychologia, 2012
In order to maintain goal-directed behavior in a changing and distractive environment, one needs to continuously monitor one's own performance and adjust it in case of unfavorable outcomes. One aspect of behavioral adjustment commonly observed in reaction time tasks is an increase in response time in trials following an error, referred to as post-error
