Complexity of central processing in simple and choice multilimb reaction-time tasks. [PDF]

open access: yesPLoS ONE, 2014
The default mode of the motor system is a coupling between limbs. However, in some movements, a decoupling is required and thus calls for selection and facilitation/inhibition processes.

The Effect of Limb Weight Gain on Premotor and Motor Components of Simple and Discriminative Reaction Time in Young and Elderly Men [PDF]

open access: yesرشد و یادگیری حرکتی ورزشی, 2015
The effect of weight and force is one of the most important factors to organize and perform reaction time (RT) tasks. The elderly are involved in this variable when they gain weight.

Accelerating Reaction Network Explorations with Automated Reaction Template Extraction and Application [PDF]

open access: yes, 2023
Autonomously exploring chemical reaction networks with first-principles methods can generate vast data. Especially autonomous explorations without tight constraints risk getting trapped in regions of reaction networks that are not of interest.

Audio–visual Reaction Time in Different Age Groups in Normal Individuals: A Cross-sectional Study

open access: yesJournal of the Scientific Society
Background: Reaction time (RT) is a simple yet sensitive measure of sensorimotor and cognitive processing. As life expectancy increases, understanding age-related changes in RT is essential to assess the functional implications of aging on everyday tasks

Global Stability of a Premixed Reaction Zone (Time-Dependent Liñan’s Problem) [PDF]

open access: yes, 1990
Global stability properties of a premixed, three-dimensional reaction zone are considered. In the nonadiabatic case (i.e., when there is a heat exchange between the reaction zone and the burned gases) there is a unique, spatially one-dimensional steady ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Classical reaction time and anticipation reaction time in a simple visual reaction time task [PDF]

open access: yes, 1973
The purpose of the study was to investigate performance on anticipation reaction time and classical reaction time as a function of practice. In the anticipation reaction time condition, the foreperiod was held constant, while in the classical reaction ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
