The multilayer dynamic network model has been proposed as an effective method to understand the brain function. In particular, derived from the definition of clustering coefficient in static networks, the temporal clustering coefficient provides a direct measure of the topological stability of dynamic brain networks and shows potential in predicting altered brain functions. However, test–retest reliability...
Protozoan mitochondrial tRNAs (mt-tRNAs) are repaired by a process known as 5′-editing. Mt-tRNA sequencing revealed organism-specific patterns of editing G–U base pairs, wherein some species remove G–U base pairs during 5′-editing, while others retain G–U pairs in the edited tRNA. We tested whether 3′–5′ polymerases that catalyze the repair step of 5′-editing exhibit organism-specific preferences...
Ratios of n-heptane (hep) to toluene (tol) affect the solubility of the asphaltenes in heavy oil extraction processes. Consequently phase changes and time after mixing n-heptane and heavy oil in toluene are important for understanding produced emulsions. The kinetics of phase change when n-heptane is added to toluene-diluted heavy oils, and the thermodynamic properties of partially deasphalted heavy...
Emulsified water droplets (WD), dispersed solids (DS), and precipitated asphaltenes (PA) form aggregates when bitumen emulsions are treated with aliphatic solvents. The WD/DS/PA aggregates in solvent-diluted bitumen exhibit zone settling and the settling rate is strongly influenced by aggregate structure. In this work, procedures were developed for determining structural parameters of the aggregates...
When bitumen emulsions are diluted with aliphatic solvents at solvent-to-bitumen ratios above a certain value, water droplets, solids, and precipitated asphaltenes tend to form clusters that are much larger than the individual components. This work demonstrates that bitumen emulsions diluted with aliphatic solvent exhibit settling behavior distinctly different from that of bitumen emulsions diluted...
