CALCULATIONS of the direction of magnetization associated with seamounts usually employ a method first described by Vacquier 1 . The seamount bathymetry is approximated by rectangular blocks and the direction of
Given the regression model: Y = b + bX, Find the estimator for b under the least-squares method. Consider the following sample data: a. Calculate the sample covariance. b. Interpret the sample covariance. A. The covariance indicates that x and y have a positive linear ...
This problem can be analyzed using the replica method from statistical physics of disordered systems33, treating the training set as a quenched disorder. Our calculation is outlined in the Methods and further detailed in the Supplementary Information. Here we present our main results. ...
They were selected by a quota sampling method to ensure the representativeness of the variety of farms in each region. The structural variables considered in sampling were farm orientation, use of grazing resources on farms, farm's geographical location in the region and farmer's age. Farmers' ...
Spatiotemporally Patterned Everyday Activities and Mental Health 1785 Method Data Collection and the Sample The data used in this study are derived from a household survey conducted in Shanghai in 2018. A multistage stratified sampling method was adopted to recruit respondents from different districts ...
On the other hand, if we use the method used in this study to back-calculate the fork length from multiple vertebral increments in a single individual, we can confidently use only a part of increments determined, and there is no need to take into account the growth of the marginal area....
This method allows us to ask whether bio- geographic isolation (distance within phylobetadiversity NMDS space) predicts metrics such as species richness. That is, do biogeographically close assemblages (points near each other in phylobetadiversity NMDS space) have similar diversity levels, and do ...
Learn the method of plotting a graph from any given function. Understand the plotting of the graph by joining the points obtained from the given function. Related to this QuestionSketch the vector field F. F(x, y, z) = ...
From the list of 112 post-mining sites with available information about age, size, vegetation and reclamation method (Woźniak 2010), we excluded 31 sites differing in size, land-use patterns in the neighbourhood, thermal activity or were artificially shaped. As these factors could significantly ...
The Taylor expansion is a mathematical method that accurately approximates a function by summation of linear and nonlinear terms. Its linear terms are the first-degree polynomial terms and nonlinear terms are higher-degree polynomial terms. In the nCREANN method,\({f}^{{Lin}}\)is a part of...
