Normalize the relation \( R \) that has the attributes: \( a, b, d, e, f, g, h, j, k, l, s, t, w, x \) up to BCNF based on the following functional dependencies:
\[
\begin{array}{ll}
\mathrm{b}, \mathrm{e} & \rightarrow \mathrm{a}, \mathrm{d}, \mathrm{g}, \mathrm{h} \\
\mathrm{a} & \rightarrow \mathrm{f}, \mathrm{g}, \mathrm{h} \\
\mathrm{b} & \rightarrow \mathrm{j}, \mathrm{l} \\
\mathrm{k} & \rightarrow \mathrm{e}, \mathrm{s}, \mathrm{t} \\
\mathrm{e} & \rightarrow \mathrm{w} \\
\mathrm{w} & \rightarrow \mathrm{x}
\end{array}
\]
