To prevent arbitrary judgments biasing the results, we believe the estimation of adjustment factors for immigration and emigration flows should be estimated simultaneously.
We believe our estimation reflects the characteristics of the early epidemic in the province of Shaanxi, since the initial infection was introduced by students returning to universities at the beginning of the autumn term and secondary infections were generated through close contact of small clusters within the same dormitories or classes.
However, we also believe that estimation methods should appropriately balance this with information from other epidemiological data sources, including prevalence data, case-based surveillance and program data.
We also believe that estimation of COX-2 expression may serve as a prognostic tool in clinical practice and future interventional research aimed at improving survival in patients with adenocarcinoma of oesophagus.
Since this study combined spatial stratified sampling (based on grassland type and community level, sampled belowground samples to a depth of 0 100 cm) with remote sensing data, it is believed that this estimation of the stock and spatial pattern of carbon in grasslands of northern China is more accurate.
However, we believe that estimations from Eq. (13) are practically useful for the evaluation of S-wave amplitude variations in inhomogeneous crust because the Rytov approximation has been successfully applied to the analysis of vector waves (e.g., electromagnetic wave propagation; Ishimaru 1997).
It is believed that the over-estimations of the GDL resistance were mainly caused by neglecting the anisotropic nature of the GDL and/or lumping the contact resistance indiscriminately into the GDL, thus overestimating the electrical resistance of the GDL in the in-plane direction.
We have also employed a number of analytic changes that we believe strengthen the estimation process and the certainty of our final estimates.
A contributing factor is, we believe, the imprecise estimation terminology in use.
Therefore, it is reasonable to believe that age estimation performance could be improved by first conducting age group classification and then estimating the age depending on the classified age group, which is a potential future research direction.
