Dear Editor,B-Raf,the main effector of Ras in the mitogen-activated protein kinase(MAPK)pathway,is among the most highly mutated kinases in human cancer[1].About 40%-60%of melanoma patients harbor B-Raf mutations,of which∼90%involve V600E and V600K.B-RafV600E is more frequent(60%-80%)than B-RafV600K(10%-30%).Substitution of a Val codon by Glu requires a single nucleotide change,whereas Val to Lys requires two[2].This is in line with melanoma patients harboring the V600K mutation,who usually suffer from higher sun exposure that may induce increased DNA damage[3].Since both mutations occur at the same position of the kinase domain and are mutated to charged residues,it was believed that the B-Raf V600E and V600K mutantswould share a similar behavior,and in clinical trials,patients with V600E and V600K mutations have been recruited into the same cohort.

We report two models of the lateral displacement of acoustic-wave scattering on a fluid-solid interface that reveal an acoustic analog of the Goos-Hainchen effect in optics. This acoustic analog is called the acoustic Goos-Hainchen effect. Using newly proposed models, we made numerical calculations for the system ofa water-Perspex interface. Specifically, in the post-critical-angle region, we observed a lateral displacement （and transition time） of the reflected P-wave with respect to the incident P-wave. The first arrival of the acoustic signal from the interface is found to be a reflected P-wave rather than the sliding-refraction P-wave usually described in traditional acoustic-logging sliding P-wave theory. For both proposed models, the effective propagation speed of the reflected P-wave along the interface depends on not only the physical properties of the interracial media but also the incident angle. These observations are intriguing and warrant further investigation.
