In this paper, we use Daubechies scaling functions as test functions for the Galerkin method, and discuss Wavelet-Galerkin solutions for the Hamilton-Jacobi equations. It can be proved that the schemes are TVD schemes. Numerical tests indicate that the schemes are suitable for the Hamilton-Jacobi equations. Furthermore, they have high-order accuracy in smooth regions and good resolution of singularities.

Complement C1q was proved to be able to regulate the polarization of macrophages to the anti-inflammatory phenotype(M2 polarized),acting as an anti-inflammation molecule independent of the classical complement pathway.A high level of C1q expression has been detected in the tumor microenvironment(TME)of diverse tumors,including non-small cell lung cancer,in which C1q could be considered a predictor of poor prognosis.
