Mutant-based model of two independent pathways for carotenoid-mediated chloroplast biogenesis in Arabidopsis embryos [PDF]

open access: yes, 2019
Chloroplasts are essential for autonomous plant growth, and their biogenesis is a complex process requiring both plastid and nuclear genome. One of the essential factors required for chloroplast biogenesis are carotenoids.

Physical Activity Modulates Corticospinal Excitability of the Lower Limb in Young and Old Adults [PDF]

open access: yes, 2017
Aging is associated with reduced neuromuscular function, which may be due in part to altered corticospinal excitability. Regular physical activity (PA) may ameliorate these age-related declines, but the influence of PA on corticospinal excitability is ...

Cerebellum to motor cortex paired associative stimulation induces bidirectional STDP-like plasticity in human motor cortex [PDF]

open access: yes, 2012
The cerebellum is crucially important for motor control and adaptation. Recent non-invasive brain stimulation studies have indicated the possibility to alter the excitability of the cerebellum and its projections to the contralateral motor cortex, with ...

Nudged-elastic band method with two climbing images: finding transition states in complex energy landscapes [PDF]

open access: yes, 2014
The nudged-elastic band (NEB) method is modified with concomitant two climbing images (C2-NEB) to find a transition state (TS) in complex energy landscapes, such as those with serpentine minimal energy path (MEP).
