Although some nanostructures, such as nanoparticles, nanofibers, and mesoporous silica, have been tested as immobilization materials to improve the surface-area-to-volume ratio, limitations in terms of dispersion in solution, a substrate diffusion barrier, efficiency of enzyme immobilization, and ability to recycle still remain.
Power efficiency is investigated when the transmitter is subject to a peak-to-average power ratio (PAR) limitation or a peak power limitation.
They considered the cases with and without fairness considerations, with and without low signal-to-noise ratio (SNR) limitation on the BS-to-relay links, assuming fixed subcarrier allocations.
However, the cost of fast, high-resolution imaging is a loss of SNR, which can compromise BOLD contrast-to-noise ratio – a limitation that requires increased experiment durations to allow for averaging additional stimulus presentations.
In addition to inappropriate ventilator settings – high respiratory rate together with high inspiratory to expiratory ratio – airflow limitation caused by bronchial injury promotes air trapping [ 22, 23].
Batch cultures with balanced C/N ratios (17) accumulate proteins (up to 44% w/w) as the major cell component; a high C/N ratio (nitrogen limitation during the stationary phase) significantly increases the dry cell mass and yields a high lipid content (up to 52% w/w).
Patients with CRS demonstrated an incremental 1.04 ± 0.3 workdays lost per year along with significant increased adjusted odds ratios for activity limitation (odds ratio, 1.54), work limitation (1.50), and social limitation (1.49, all p <.005) but not cognitive limitation (1.05, p =.213).
This "rule" delineated the various income, debt-income ratios, fee limitations among other metrics that banks must verify for each borrower for the loan to be considered a "qualified mortgage".
EtCO2 has been efficiently used for decades in intubated anesthetized patients [7] to monitor PaCO2 and ventilation, although many limitations have been recognized, particularly for patients suffering from chronic respiratory diseases (increased VD/VT ratio [8], airflow limitation) or hemodynamic instability leading to ventilation-perfusion mismatches [7,9].
The curvature, sliding velocity, contact ratio, and the limitation of undercutting can be derived directly from the equation of line of action.
