Given the limitation of standard molecular dynamics (MD), enhanced sampling was employed to overcome the energy barrier.
For those cases where allosteric regulation is known to occur, but one of the ends is unknown, long simulations (alone 106, 107 or with enhanced conformational sampling) are required.
Results from mtDNA genomes show promise as an additional independently evolving genome for developing phylogenetic hypotheses for nematodes, although substantially increased taxon sampling is needed for enhanced comparative value with nuclear rDNA.
However, such enhanced sampling frames are generally restricted to countries operating national registers (mainly in the Nordic region); in other countries, an alternative approach is needed to make comparisons between respondents and nonrespondents.
Atomistic molecular dynamics simulations complemented by enhanced sampling approaches are increasingly used to probe the effect of mutations on the conformational dynamics and on the underlying conformational free energy landscape of proteins.
Explicit solvent molecular dynamics simulations (in total almost 800 ns including locally enhanced sampling runs) were applied with different ion conditions and with two force fields (AMBER and CHARMM) to characterize typical geometries adopted by the flanking bases in the RNA kissing-loop complexes.
It should be pointed out in any comparison of PD and MTD that MTD is "only" an enhanced sampling approach, whereas PD is a combined multi-scale enhanced sampling method.
The ratio of slopes of the segments which approximate the experimental data points for structured and standard sensors within the range of enhanced sensitivity for this sample is equal to 4.4.
By deliberately creating shell porosity through KOH chemical activation, at an optimized KOH/HCS mass ratio of 1/4, the catalytic performance for the oxidative carbonylation of methanol to dimethyl carbonate (DMC) of the activated sample is enhanced remarkably with TOF up to 8.6 h−1 at methanol conversion of 17.1%.
Although our geographically- and taxonomically-enhanced sampling scheme was far from exhaustive, and heavily weighted toward Moorean and Tahitian taxa (Table 1), the incorporation of museum and captive (zoo) samples allowed us to genotype numerous extinct and extirpated taxa that span the family's range; the Solomon Islands being the only major archipelago that lacked a representative.
