Model-Based and Model-Free Social Cognition

open access: yes, 2019
Do habits play a role in our social impressions? To investigate the contribution of habits to the formation of social attitudes, we examined the roles of model-free and model-based reinforcement learning in social interactions—computations linked in past

Towards Model-Free Tool Dynamic Identification and Calibration Using Multi-Layer Neural Network

open access: yesSensors, 2019
In robot control with physical interaction, like robot-assisted surgery and bilateral teleoperation, the availability of reliable interaction force information has proved to be capable of increasing the control precision and of dealing with the ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Model-free Model-fitting and Predictive Distributions [PDF]

open access: yes, 2010
The problem of prediction is revisited with a view towards going beyond the typical nonparametric setting and reaching a fully model-free environment for predictive inference, i.e., point predictors and predictive intervals.

Dopamine Enhances Model-Based over Model-Free Choice Behavior [PDF]

open access: yes, 2012
SummaryDecision making is often considered to arise out of contributions from a model-free habitual system and a model-based goal-directed system.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Rigid-Link Manipulators: Model-Free Control

open access: yes, 2018
The chapter analyzes model-free nonlinear control approaches for multi-DOF rigid-link robots, based on Lyapunov methods. There, one comes against problems of minimization of Lyapunov functions so as to ensure the asymptotic stability of the control loop.

Enhanced Speed Loop Control Strategy for Yokeless Axial FluxSwitching Permanent Magnet Motors [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization
This paper presents an Enhanced Model-Free Sliding Mode Control (EMFSMC) method tailored for the speed loop of a 12-slot/19-pole yokeless and segmented armature axial flux-switching permanent magnet (12S/19P YASA-AFFSSPM) motor, focusing on robustness ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
